Abstract:In order to solve the problems of uneven cotton feeding and uneven cotton fleece of the comber，and provide reference for the running of comber and design of new comber，theoretical analysis is made on nipper shedding and feeding mode of the comber.The reasons why the nipper shedding is smaller or larger than the standard value due to the inaccurate adjustment of nipper shedding in forward cotton feeding and backward cotton feeding are analyzed.Eccentric gear of the tension shaft and the eccentric rotation angle θ of and tension shaft is adjusted under the gear transmission mode and connecting rod transmission mode to ensure the nipper shedding.It is pointed out that the shedding and closing time of the nipper and the feeding length of the cotton feeding roller are the key factors affecting the running quality of the comber.The number of teeth of the cotton ratchet determines the length of the amount of cotton to be fed per nipper.Due to the manufacturing error of the cotton ratchet，the appearance of the cotton fleece becomes worse.The nipper shedding K is calculated and adjusted in detail according to positional relationship of nipper ratchet and pawl as well as the actual situation in design and adjustment，and the adjusting device of back nipper shedding of noil gauge is designed and adjusted，to ensure the consistency of nipper shedding after adjustment，so that the feed roller can feed cotton accurately per nipper，fundamentally ensuring the quality of combed sliver.
Key Words:comber；nipper shedding；cotton feeding；roller；ratchet；pawl；eccentric rotation angle
