Abstract

The invention relates to a combing cylinder with a small cambered surface and low combining strength, the total number of teeth is 4000-10000, the cambered surface angle of the cylinder is 60-85 degrees, and the cylinder is equally divided into three or four subregions. Compared with the prior art, the combining surface is reduced by 50% on the basis that tooth density in all the subregions is not changed basically, and the number of the subregions is reduced. First, the cylinder combing surface is reduced, the total tooth number of the cylinder is effectively reduced, and the combining processing requirement for combed yarn and the low noil rate is met; second, the cylinder cambered surface is reduced, the weight of the cylinder is effectively reduced, energy consumption is reduced, and collision caused by mismatch of the cylinder and a nipper is avoided, which is beneficial for safety operation of equipment; in addition, the number of the subregions is small, which is beneficial for reducing cotton embedding of the cylinder, and the manufacturing difficulty and machining cost of the combing cylinder are reduced.

Description

technical field [0001] The invention relates to a textile part, especially a combed cylinder with small arc surface and low carding strength, which belongs to the field of textile technology Background technique [0002] The combing cylinder is the core component of the combing machine. Its main function is to comb the front end of the cotton bundle, remove neps, short fibers and impurities, and improve the straightening, parallelism and separation of fibers. Under certain other conditions, when the total number of combing cylinder teeth is large, the carding degree of the cylinder is large, neps are excluded, there are many short fibers, the combing noil rate is high, and the spinning cost is high, which will affect the economic benefits of spinning enterprises . When producing combed yarns with coarser yarn counts and lower quality requirements, under the condition of ensuring the combing quality requirements, in order to reduce costs, the combing noil rate is generally r...
