Embodiment

[0013] As shown in the figure, several sets of sawtooth groups 2 are installed on the carding area of ​​the base 1, and the sawtooth density from the front to the rear of the carding area is from thin to dense. In the frontmost part of the carding area of ​​the base 1, several needle strips 3 using comb needles are also installed, and the density of the needle strips 3 is thinner than that of each sawtooth group 2 sawtooth densities thereafter. Combing needles can adopt circular needles, flat needles, etc., and there are at least two or more rows of combing needles on the needle bar 3 installed in the present embodiment. The sawtooth group 2 is generally formed by assembling the tooth piece, the spacer piece and the end piece through the plate pin.

[0014] When the cylinder is actually working, it needs to be installed on the cylinder shaft with screws, and the contact connection distance between it and the cylinder shaft directly affects the carding distance. Generally, the...

Abstract

The invention provides a comb pin saw tooth cylinder of a cotton comber. The cylinder comprises a base; a combing area of the base is provided with a plurality of groups of saw tooth groups; the saw tooth density from the front part to the back part of the combing area is from thin to thick; and the forefront of the combing area of the base is also provided with a plurality of pin strips using comb pins, and the density of the comb pins of the pin strips is lower than that of the saw teeth of saw tooth groups arranged behind the pin strips. In the cylinder, the forefront of the combing area of the cylinder is provided with the comb pins, so that the puncturing, finishing and shredding effects are better when combing, and the fiber is not damaged; and the middle-back part of the combing area adopts a saw tooth cylinder structure, the effects of removing cotton neps, impurities and flock powder are better in combing, and the high-speed and high yield are supported. The cylinder has the advantages of integrating the advantages of the comb pin cylinder and the saw tooth cylinder, discarding demerits, greatly improving the carding quality and reducing the consumption of raw cotton, along with skillful and reasonable structure.

Description

Technical field: [0001] The invention relates to a cylinder for a cotton combing machine. Background technique: [0002] Cotton combing machine cylinder is the main carding part on the cotton combing machine, and the carding effect is closely related to the quality of cotton spinning yarn. When the cylinder is working, the main function of the front part of the carding area is to pierce the cotton layer, arrange the disordered cotton fibers, and loosen the fiber bundles. The middle and rear part of the carding area of ​​the cylinder is mainly used to card to remove neps, impurities and short fibers in the cotton layer. [0003] There are two types of cylinders. The most traditional one is the comb needle cylinder. The comb needles are planted into needle plates by means of welding and gluing. onto the base. This kind of needle cylinder has a strong puncture force, can penetrate the small roll cotton layer, and has a good finishing and opening effect, but the process of pl...
