Abstract

The utility model relates to a roller for a spinning machine. The surface of the roller is processed out a helical tooth whose tooth shape is in a semicolumn shape. The utility model solves the problems of the yarn number and the insufficient yield affected by the nonuniform yarn strip and poor strength which is generated by that the surface of the existing roller is easy to stick with the fibrilia in the process of working. The utility model is widely used for the tape condenser, the sett frame, the drawing frame, and the fly frame of the flax textile industry.

Description

Roller for spinning machine

The utility model relates to the weaving loom accessory.

The roller that uses on the weaving loom has wooden at present, rubber, ox-hide, material systems such as vulcan fibre several, the surface of roller all is flat, the contact area of roller and roller is big in the course of the work, easily produce static, in the process of processing flax, can cause sticking flax fibre, linen fibre itself has a kind of colloid, extending through in the journey some colloid at the flax fibre bar takes off, be bonded on the surface of roller easily, this is the another reason that causes sticking flax fibre, the sticking flax fibre of surface of roller has caused quality for the linen textile industry, heavy losses on output and the economic benefit, addressing this problem becomes urgent need.

Task of the present utility model is: design a kind of in process the surface do not produce the roller of sticking flax fibre.

Task of the present utility model realizes as follows: process helical tooth at cylindrical surface of roller.

Above-mentioned said tooth be shaped as half round post.

The utility model produces slight in flax process owing to process the Luo Xuanchi that profile of tooth is half garden at surface of roller like this

Degree is held the ramie stripes fiber that comes out that stretches mutually tightly, avoids a large amount of linen fibers of surface of roller; Because surface of roller processes helical tooth, the surface is a concave-convex like this, contact-making surface is very little in drawing process, it is also little that friction produces static, and the gravitation of static is dispersed in the difficult sticking flax fibre of surface of roller, the colloid of itself taking off in the linen fibre drawing process simultaneously also is difficult for causing matter glue point at surface of roller, can avoid the sticking in a large number flax fibre of surface of roller; Because surface of roller does not glue flax fibre, can improve the number of the dried evening ratio of sliver, intensity and yarn, reduce tufted yarn in the yarn, save a large amount of flax raw materials.

Fig. 1 is the utility model front view;

Fig. 2 is the A-A cutaway view of Fig. 1;

A most preferred embodiment of the present utility model, as figure, go out half-cylindrical helical tooth in roller 1 Surface Machining, be lined with metallic framework 2 in the roller, sieve swing angle of helical tooth is chosen as 16 °, and the material of roller can be rubber, plastics or rubber and plastic, and adopting any all is to be made by the same material of two kinds of hardness, difference of hardness is 10 between the present embodiment roller 1 and 3 about 10.

Claims

1, a kind of textile machines roller is characterized in that: surface of roller processes semicolumn profile of tooth helical tooth.

2, roller as claimed in claim 1 is characterized in that, roller is made by the same material of two kinds of different hardness.
