Counting the commonly used accessories of rotary spinning machines

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.
