The spinning cup (rotor) joint is one of the core components of the rotor spinning machine, which directly affects the quality of the yarn (such as evenness and hairiness) and the operation of the equipment. It mainly includes components such as the spinning cup body, high-speed bearings, sealing rings, positioning pins, etc.

Cleaning and lubrication

Wipe the surface of the spinning cup shaft with a dust-free cloth dipped in alcohol to remove oil stains and fiber residues; Apply a small amount of high-speed bearing grease (not too much to avoid absorbing fibers) to the inner ring of the new joint bearing to ensure even lubrication of the bearing.

Installation method

Align the new joint with the keyway of the spinning cup shaft, gently push it in until the bottom of the joint fits the shaft shoulder. During installation, it is necessary to keep it level to avoid tilting and uneven bearing force on the shaft. If encountering resistance, check if the keyway is aligned and do not forcefully press it.

Installation of sealing ring and peripheral components

When installing the sealing ring, ensure that it is fully aligned with the groove of the spinning cup seat, without distortion or gaps (to prevent vacuum leakage from affecting spinning quality). Then install the spinning cup cover and combing roller in sequence, and use a torque wrench to tighten the screws according to the equipment manual (such as the combing roller screw torque is usually 2-3N · m), to avoid over tightening and causing component deformation.

The model adaptation of Lida cup spinning accessories is the core link in improving yarn quality. Different models and production requirements correspond to different accessory parameters. Choosing the wrong model not only leads to equipment failures and increased breakage rates, but also directly affects yarn quality.

Clearly define one's own model and basic configuration

The core models of Lida cup spinning include R40, R60, R70, R90 and other series, with significant differences in accessory specifications for each series. Firstly, it is necessary to confirm the specific model of the equipment - usually the body nameplate will indicate the complete model (such as R60-1200, where "1200" represents the number of spindles and the core model is R60). In addition, it is necessary to record the production batch of the equipment (some accessories will be optimized and upgraded with the batch), as well as the key component parameters of the current configuration (such as rotor diameter, combing roller type), which are the basis for subsequent accessory selection.

Select targeted accessories based on production needs

The accessory model needs to match the yarn variety, yarn count, and production target.

Verify compatibility after installation

After selecting the accessories, the compatibility needs to be verified through the following steps:

Installation inspection: Ensure that the accessories are installed in place (such as the torque of the rotor meeting the manual requirements: usually 25-30N · m), without looseness or jamming.

Trial operation: Start up and run for 30 minutes, observe the vibration value of the equipment (≤ 0.5mm/s is normal) and the breakage rate (≤ 1 time/ingot · hour).

Yarn testing: Testing the dry CV value, fuzz index, strength and other indicators of the yarn. If the indicators are consistent or better than those obtained when using original accessories, it indicates successful adaptation.

The process of model adaptation for Lida cup spinning accessories: starting from confirming the model, locking in core parameters based on production needs.

The selection of Titan cup spinning accessories should focus on four core aspects: machine adaptation, raw material characteristics, process parameters, and quality requirements. The following will explain the key selection points from the perspective of key accessories.

1、 First, clarify the host model and core parameters

The mainstream models of Titan include TQF268, TQF-K80, TQF-K90, etc. The installation dimensions, speed limits, and power configurations of different models vary. Before selecting, check the host nameplate to confirm core parameters such as spinning cup speed range, combing roller diameter, bearing installation position, and number of spindles, in order to avoid size discrepancies or performance overload.

2、 Core accessory model selection

Spinning cup (rotary cup): Select the diameter model according to the yarn count and raw material. Choose T50 (50mm) for medium yarn and T42 (42mm) for fine yarn; Choose DN34/T34 high-speed spinning cup for synthetic or blended fibers, suitable for 100000-120000 r/min, with priority given to diamond ceramic material.

Comb roller: The model includes tooth profile, tooth density, and diameter, suitable for Titan's WS-OB/OK series. WS-OB174DC (high tooth density, strong combing); Polyester cotton blend with WS-OK61DC (sparse teeth, large angle, anti entanglement); Choose WS-OK40DC for chemical fiber, with shallow teeth and easy transfer. The roller body is preferably made of all aluminum hollow design, which can be returned repeatedly and runs stably.

Titan Cup Spinning Comb Roller

Rotary cup bearing: Core model 73-1-31G/T (suitable for Titan, Rifa, etc.), with a speed of ≤ 80000 r/min, choose the ordinary model, and 80000-120000 r/min, choose the 73-1-31T high-speed sealed model. The double groove double row ball bearing design is dust-proof and has a long service life. The commonly used comb roller bearings are 76-3-7k, matching the installation size of Titan.

Ring gear/transmission components: Titan 33 ring gear is compatible with mainstream models, with an inner diameter of approximately 59mm and made of nylon or alloy material.

3、 Combining raw materials and process refinement to match

Chemical fiber/blend: low tooth density combing roller+high-speed spinning cup+high-speed bearing, anti-static and easy to transfer.

Coarse count yarn: Large diameter spinning cup+coarse toothed combing roller, increases production and reduces breakage.

Fine yarn: small diameter spinning cup+fine toothed combing roller, ensuring strip dryness and reducing details.

4、 Verify compatibility and quality

Prioritize selecting Titan original or certified accessories, verify installation dimensions, interface specifications, and speed limits to avoid compatibility risks. Sample testing before bulk procurement, monitoring yarn dryness, breakage rate, accessory temperature rise, and verifying model compatibility.

In short, the selection of Titan rotor spinning accessories should be based on the model, raw materials, process, and quality, matching the model, taking into account the quality of the equipment yarn, and reducing operation and maintenance costs.

The replacement and loading/unloading of the spinning cup joint is a key step in the maintenance of the rotary spinning machine, which requires strict adherence to operating standards and attention to details such as cleaning, lubrication, and installation. Standardized operation can not only improve equipment operating efficiency, but also reduce production costs. Operators should receive regular training, familiarize themselves with equipment structure and maintenance requirements, and ensure accurate operation at every step.

Regular cleaning

Clean the fiber accumulation on the inner wall of the spinning cup every 800-1000 hours of operation (using a cleaning brush or compressed air) to avoid fiber entanglement and overheating of the bearing.

Lubrication and maintenance

Supplement bearing grease every 2000 hours, with an appropriate amount to cover 1/3 of the bearing balls each time. Excessive amount can cause fiber adsorption.

Life management

The service life of the spinning cup joint is usually 3000-5000 hours, and it should be replaced in a timely manner according to the type of yarn (such as coarse yarn, which wears out faster). If the wear on the inner wall of the spinning cup is found to be greater than 0.1mm, it should be replaced immediately to avoid affecting the quality of the yarn.

As one of the core equipment in modern spinning industry, the rotary spinning machine has become the "main force" of textile enterprises due to its advantages of short process and adaptability to various raw materials. The operation and yarn quality of a rotary spinning machine cannot be achieved without the synergistic effect of various key components. The performance of accessories directly affects production efficiency and yarn quality at every stage from feeding to winding. The following are common accessories and their core functions for rotary spinning machines:

1、 Feeding system: the "level" of evenly feeding cotton

The core task of the feeding system is to evenly transport the cotton strip (or synthetic fiber strip) to the combing process, and the key accessories include:

Cotton feeding roller: composed of metal roller and rubber coating layer, it controls the feeding speed and pressure of cotton strips by cooperating with the cotton feeding plate. The groove design on its surface can increase friction, prevent the cotton strip from slipping, and ensure consistency in feeding amount.

Cotton feeding board: forms a clamping area with the cotton feeding roller, guiding the cotton strips into the combing mechanism. The angle and gap of the board need to be adjusted. If it is too large, it may cause uneven feeding, while if it is too small, it may damage the fibers.

Providing cotton loops: Some models use loops instead of cotton feeding boards, which are better adapted to different thicknesses of cotton strips through elastic wrapping layers, reducing fiber damage.

The coordination of these accessories directly determines the fiber uniformity in the subsequent combing process and is the foundation of yarn quality.

2、 Sorting system: the "core battlefield" of fiber combing

The combing system is the soul of rotary spinning, responsible for breaking down cotton strips into individual fibers and removing impurities. Key accessories include:

Combing roller (combing roller): usually made of stainless steel or aluminum alloy, coated with metal wire cloth on the surface. Its high-speed rotation (thousands to tens of thousands of revolutions per minute) loosens and combs the cotton strips into single fibers. The tooth shape, density, and sharpness of the needle cloth directly affect the combing effect - high tooth density can easily damage the fibers, while low tooth density can result in insufficient combing.

Sorting needle cloth: divided into metal needle cloth and elastic needle cloth. Metal needle cloth has high combing efficiency and is suitable for high-speed models; Elastic needle cloth is more suitable for handling fragile fibers such as wool. Regular cleaning and replacement of needle cloth are key to maintaining the quality of combing.

Dust removal knife and cotton guide board: The dust removal knife is installed under the combing roller, and impurities and short fibers are separated by adjusting the angle; The cotton guide board guides the combed fibers to flow towards the rotor, avoiding fiber scattering or blockage.

The performance of combing system accessories directly affects the cleanliness and single fiber state of fibers, and is the key to reducing yarn fuzz and improving strength.

3、 Condensed twisting system: the 'magic' of yarn formation

The coagulation and twisting system recondenses the combed single fibers into yarn and twists them. The core components include:

Spinning cup: The iconic accessory of spinning cup, usually made of ceramic or metal material. Ceramic rotor is heat-resistant and suitable for high-speed spinning (up to 100000 revolutions per minute or more); The cost of metal cups is relatively low. A coagulation groove (U-shaped, V-shaped, or curved) is set inside the rotor, where fibers aggregate into strands. The shape of the groove affects the transfer efficiency and yarn strength of the fibers.

Anti twist head (false twist device): installed at the top of the yarn guide tube, it generates false twist through friction with the yarn, reducing the transmission of twist to the inside of the rotor. Commonly used ceramic or polyurethane materials require regular inspection for wear and tear.

Yarn guide tube: guides fibers from the combing roller into the rotor, and its positional accuracy directly affects the coagulation effect of fibers - deviation can cause uneven strands, which in turn affects the quality of the resulting yarn.

Sorting device: including a sorting pipe and a fan, which discharges impurities and short fibers separated during the sorting process outside the machine, keeps the inside of the rotor clean, and avoids impurities from mixing into the yarn.

The components of the cohesive twisting system determine the twist, strength, and evenness of the yarn, which is the core technology of rotary spinning.

Conclusion

The accessories of the rotary spinning machine are like the "organs" of the machine, and each component is interrelated and indispensable. Reasonable selection of accessories (such as ceramic rotor, metal needle cloth) and regular maintenance (cleaning needle cloth, replacing worn parts) are key to improving the production efficiency and yarn quality of rotor spinning. With the development of textile technology, new types of accessories continue to emerge, which will further promote the development of rotor spinning towards higher speed and higher quality.

As a modern spinning equipment in the spinning industry, the rotary spinning machine has become the main model in the fields of cotton spinning and chemical fiber spinning due to its advantages of short process, high speed, and strong adaptability. Its stable operation and yarn quality cannot be achieved without the synergistic effect of a series of precision accessories. The following are the commonly used core components and their functional values of rotor spinning machines:

1、 Feeding system: the "checkpoint" of raw material transportation

The feeding system is the key to evenly feeding cotton strips or fiber bundles into the combing process, and the core components include feeding rollers and feeding boards.

Feeding cotton roller: With grooves or patterns on the surface, the cotton strips are fed into the combing area in a quantitative and uniform manner by cooperating with the cotton feeding board. The speed and pressure directly affect the stability of the feeding amount. If the roller is worn or the groove is blocked, it can easily lead to uneven feeding and cause uneven yarn thickness.

Cotton feeding board: forms a grip area with the cotton feeding roller, and its curved surface angle needs to be adjusted with the gap between the roller - a gap that is too large can easily leak cotton, while a gap that is too small can cause severe fiber damage.

2、 Sorting System: Fiber Refining 'Processing Station'

The core component of the combing system is the combing roller (also known as the piercing roller), which is responsible for decomposing the fed fiber bundle into individual fibers and removing impurities.

Combing roller: The surface is densely covered with needle teeth or serrations, and the centrifugal force generated when rotating at high speed (up to 8000-15000 r/min) throws the fibers towards the rotor. The density, angle, and material of the needle teeth directly affect the quality of combing: the higher the density of the needle teeth, the more thorough the combing, but it is prone to clogging; Ceramic or hard alloy materials have strong needle teeth and are suitable for spinning high count yarns. During daily maintenance, it is necessary to regularly clean the cotton debris between the needle teeth to avoid fiber entanglement.

Each component of the rotary spinning machine serves a specific function, and its accuracy and condition directly affect the quality and production efficiency of the yarn. For example, wear on the rotor can lead to a decrease in yarn strength, clogging of the combing roller teeth can cause uneven combing, and wear on the grooves of the drum can result in poor barrel forming. Therefore, it is necessary to regularly check the wear and tear of accessories in daily production, replace vulnerable parts in a timely manner, and ensure the stable operation of equipment.

Airflow spinning (rotor spinning) anti twist head (false twist disc) is a core vulnerable component that directly determines twisting efficiency, yarn strength, fuzz, breakage, and dryness. The selection core revolves around four dimensions: material, aperture, curved structure (enclosing angle/arc), model adaptation, yarn count/raw material/process matching, and is comprehensively selected based on the type of machine and spinning requirements.

1、 Basic function of anti twist head

The core two functions of the anti twist head (false twist disc) are:

Twist blocking: creates a twist trap, preventing the spinning cup from twisting back and transmitting upwards, locking in the twist at the peeling point;

False twist: Additional false twist is generated by the friction and winding of the yarn, which enhances the dynamic strength of the yarn tail, reduces breakage, and optimizes hairiness and slimness.

The strength of the false twist effect is equal to the friction coefficient multiplied by the yarn wrap angle multiplied by the contact diameter, and all selection parameters are based on this formula.

2、 Selection dimension: Material selection (friction performance, yarn quality)

The three mainstream materials directly determine the friction coefficient, feather, and applicable working conditions, and the on-site comparison data is complete.
