Problems solved by technology

[0004] The conical needle-type top comb fails to meet the requirements of the majority of users for removing short-lint and neps during use, and the accumulation of fluff (lint) on the carding needles is relatively serious, and the accumulation is more and more, making life difficult. Downtime is required to clean the lint from the top comb needles, reducing performance and thus reducing work efficiency

Embodiment Construction

[0023] A toothed self-cleaning top comb for cotton combing machines, which includes a straight plate 1, a toothed plate 2 and a curved plate 3, a row of toothed plates 2 are connected between the straight plate 1 and the curved plate 3, and the toothed plates 2 are selected from high-quality High-carbon structural steel, the surface of the gear piece is polished, the roughness is Ra0.4μm, and the heat treatment hardness is HV740±40. The cross section of gear piece 2 is wedge-shaped, where ∠α is 12°, ∠β is 18°, and ∠γ is 10°. The CEs are connected by circular arcs. The R value is 2.5mm. The CE cutting edge is clear and free of burrs. CD value is 0.2 0 -0.05 mm, the BC value of the working height of the tooth piece section is 5.5±0.015mm. This excellent tooth structure, in addition to having excellent carding performance, the short fibers, neps and impurities that are combed are not easy to accumulate and fall, and it can also prevent combing The short staples and neps that co...

Abstract

The invention relates to a teeth-like self-cleaning top comb for a cotton comber. Tooth sheets (2) are connected between a straight panel and a bent plate (3); the cross section of the tooth sheets (2) is of a wedge shape, wherein an alpha angle is 11 to 13 degrees; a beta angle is 17 to 19 degrees; and a gamma angle is 9 to 11 degrees; C and E are connected through an arc, the value of R is 2.3 to 3 mm, and edges of the C and the E are clearance angles and have no burr; the values of the C and D are 0.200 to 0.05 mm, the BC value of a working height of a tooth sheets section is 5.5+ / -0.015 mm, the value of AB is 3 mm, the value of BE is 0.6 to 0.8 mm, and the value of BF is 2.06 mm; and the alpha value of the lower end of the tooth sheets section thickness is 0.06 to 0.08 mm, and the beta value of the upper end of the tooth sheets section thickness is 0.20 to 0.25 mm. The top comb has the good carding effect, and self-cleans carded neps, flocks and impurities in the process of carding, so that the use performance of the top comb is improved and the working efficiency is improved.

Description

technical field [0001] The invention belongs to a key carding element on a cotton combing machine, in particular to a gear-type self-cleaning top comb used on a cotton combing machine. Background technique [0002] Both the cylinder and the top comb are the key carding components on the cotton combing machine. Their function is to remove the short staples, neps and impurities in the cotton clump, obtain high-quality combed slivers, and make the spun yarns have high strength. The appearance is lustrous and soft, and the woven fabric is evenly dyed and has no defects. It is a high-quality clothing fabric. The purpose of removing short fibers is to increase the strength of the yarn, and the purpose of removing neps and impurities is to improve the appearance quality of the yarn and avoid obvious defects on the cotton cloth caused by neps in the next printing and dyeing process. The straightness, parallelism and separation of the fibers are improved through the combing of the c...
