Cloth guide roller with rack

Abstract

The invention belongs to the field of textile machinery, and in particular relates to a cloth guide roller with racks. The cloth guide roller comprises a roller, roller covers, a connecting plate and the racks, wherein the roller covers are arranged on two ends of the roller, the connecting plate is fixed in the roller, the racks are arranged on the outer surface of the roller, and the cloth guide roller is characterized in that a plurality of columns of racks are uniformly installed on the surface of the roller in the radial direction, the racks are parallel to the axis of the roller, each column of rack is provided with a plurality of arc teeth, the height of arc teeth in each column of rack is gradually reduced from one end to the other end of the rack, and the height of the arc teeth of each adjacent column of rack is gradually reduced in an opposite direction. The racks on the roller are different in heights and are alternately arranged, so that the holding force for a fabric can be increased, and the slippage rate is reduced; moreover, the fabric is prevented from jumping out of the roller in the high-speed operation process, and the phenomenon that the roller is blocked by the fabric can be avoided.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a cloth guide roller with racks. Background technique [0002] In the dyeing equipment, the fabric is a cloth loop connected head to tail. It is driven by the lifting of the cloth guide roller and the hydraulic pressure or air pressure of the nozzle, and the cycle movement is constantly performed. During the fabric dyeing process, the linear speed of the cloth guide roller is required. It has a good matching relationship with the linear speed of the nozzle water pressure or air pressure pulling the fabric, otherwise it is easy to cause relative sliding, resulting in damage to the surface quality of the fabric and uneven dyeing. At present, two types of cloth guide rollers with rubber strips and stainless steel cylindrical cloth guide rollers with convex ribs are mostly used in the market. The fabric guide roller with rubber strips has a large friction coefficient and plays a goo...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problem that the existing rubber cloth guide roller is easy to fluff and damage the cloth surface, and the stainless steel cloth guide roller with convex ribs is easy to slip, the present invention provides a rack cloth guide roller, in which the rack and the roller are both made of stainless steel , has a very good protective effect on the fabric surface, and the racks are arranged in a staggered manner on the roller. During the lifting process of the fabric guide roller, the fabric guide roller has a strong grip on the fabric, and it is not easy to produce relative sliding
