Abstract

The invention provides a roller device of a carding machine. The roller device comprises an upper roller and a lower roller, wherein inward triangular grooves are carved at the upper end and the lower end of the upper roller, and the upper end and the lower end of the lower roller are set to be triangular convex ends adaptive to the grooves of the upper roller. The roller device has the beneficial effects that 1) unexpected flyings are avoided, so that the service lives of the parts are prolonged, neps are prevented from being guided into cotton silver, and flocks are reduced; and 2) the yarnlevelness CV of a product is improved by 1%, the product quality is improved, simultaneously, the production efficiency is improved, and the economical benefits are brought to enterprises.

Description

A kind of roll device of carding machine

Technical field

The present invention relates to a kind of carding machine, specifically, relate to a kind of roll device of carding machine, belong to the Weaving device technical field.

Background technology

Carding machine is a kind of important textile machinery, and its main application is comb and parallel cotton fibers prior to spinning, mainly comprises following four kinds of functions: 1) combing: make flock become filament; 2) removal of impurities: remove assorted defect, short flannel; 3) mixed: as to carry out mixing between filament; 4) slivering: process uniform sliver.

Wherein, roll device is to fine impurities residual in the web, fault, carries out grating and removes; The roll device of at present traditional carding machine is as shown in Figure 1, and the end face of its top and bottom rolls is a flat, and the end face of this shape has following weak point: be easy to generate unexpected flyings; Cause parts to break down easily; Need often maintenance, the cotton knot of generation is by in the continuous bar of substitution, and the generation of short flannel increases.

Summary of the invention

In order to overcome the weak point of prior art, the invention provides a kind of roll device of carding machine.

The roll device of carding machine of the present invention comprises topping roll and bottom roll, and the upper and lower side of said topping roll is all dug inside triangular groove, and the upper and lower side of said bottom roll is made as the triangle nose suitable with the groove of said topping roll.

Any surface finish of said topping roll and said bottom roll is hard, and wherein, the nose surface of the groove surfaces of said topping roll and said bottom roll all is made as the circular arc of 0.5cm-2cm.

The present invention has following beneficial effect:

1) avoids unexpected flyings to produce, increased the service life of parts, avoided cotton knot to be updated in the sliver, reduced the generation of short flannel.

2) the bar solid carbon dioxide that has improved product is put down CV1%, when improving the quality of products, has increased production efficiency, has brought economic benefit to enterprise.

Description of drawings

Fig. 1 is the side view of existing carding machine roll device.

Fig. 2 is the side view of carding machine roll device of the present invention.

Wherein, 1 is topping roll, and 2 is bottom roll.

The specific embodiment

As shown in Figure 2; The roll device of a kind of carding machine of the present invention; This device comprises topping roll 1 and bottom roll 2, and the upper and lower side of said topping roll 1 is all dug inside triangular groove, and the upper and lower side of said bottom roll 2 is made as the triangle nose suitable with the groove of said topping roll 1.Any surface finish of said topping roll 1 and said bottom roll 2 is hard, and wherein, the nose surface of the groove surfaces of said topping roll 1 and said bottom roll 2 all is made as the circular arc of 1cm.

The present invention is when work, and web passes from the centre of topping roll 1 and bottom roll 2, and any surface finish of topping roll 1 and bottom roll 2 is hard; Through to rolling, fine impurities residual in the web, fault etc. are carried out grating remove, improve the flat CV1% of bar solid carbon dioxide of product; Avoid unexpected flyings to produce, increased the service life of parts, reduced fault rate; Avoid cotton knot by in the substitution sliver, reduced the generation of short flannel, also improved production efficiency of products when having increased product quality.

Claims
