The process principle of needle roller is: in order to prevent encirclement and traffic jam, it is advisable to adopt the principle of "more looseness and less beating, combing instead of beating, more recovery, less cleaning, and more mixing". The specific analysis is as follows:

1. The criterion of fan speed is changed from 1300r/min to 1500r/min.

2. The principle of fiber surrounding distance: the spacing should be small, the dust rod should be installed reversely, the make-up air recovery should be increased, and the single debris area should be closed to ensure smooth fiber transmission; The spacing between the dust stick and the beater is increased by 1.5 times to reduce the excessive rubbing of the fiber and the bunching of the fiber; The spacing between the cotton feeding roller and the beater is adjusted to 12mm, and the spacing between the cotton stripper and the beater is adjusted to 1mm, which can solve the problem of fiber surrounding the comber.

3. The form criteria of the beater: choose the full-comb needle roller with gentle impact and detailed finishing effect to replace the porcupine beater.

4. The rule of beater speed: the roller speed of full carding needle is 500r/min~550r/min, and the speed of coiling beater is 750r/min~800r/min.

5. Rules for regular cleaning: regularly clean the pipeline, especially some pipe bends, and clean the burr and cotton wax every three days, which can effectively solve the appearance of fiber blockage.
