Anti-adhesion composite arc cloth guide roller

Abstract

The invention discloses an anti-adhesion composite arc cloth guide roller comprising a bearing shaft, a cylinder and end covers. The bearing shaft penetrates through the cylinder. The end covers are fixedly connected between the bearing shaft and the cylinder and located at the two ends of the cylinder. The cylinder is of a hollow structure. The outer surface of the cylinder is an arc cylinder with the high middle and the two low sides in the axis direction. A supporting mechanism is arranged at the position, between the end covers at the two ends, in the cylinder, and comprises a plurality of supporting rods. The supporting rods are fixedly connected between the outer wall of the bearing shaft and the inner wall of the cylinder. The anti-adhesion composite arc cloth guide roller is characterized in that the multiple rows of supporting rods are distributed in the axial direction of the bearing shaft, each row of supporting rods are annularly distributed between the outer wall of the bearing shaft and the inner wall of the cylinder in an array mode with the bearing axis as the center axis, the outer wall of the cylinder is provided with a polyether-ether-ketone coating, the lateral outline of the cylinder is a complete arc, and the radian of the arc ranges from 4 degrees to 6 degrees. The anti-adhesion composite arc cloth guide roller is high in strength and rigidity, good in cloth guide effect, and resistant to adhesion, corrosion, abrasion and high temperature.

Description

technical field [0001] The invention relates to the field of textile, printing and dyeing machinery and equipment, in particular to a fabric guide roller used for open-width transmission of fabrics. Background technique [0002] In the textile, printing and dyeing industry, the cloth guide roller is a commonly used component. The cloth guide roller is a cloth conveying mechanism that transfers the open-width cloth to the next process. Its length is equivalent to the width of the cloth and its cross section is circular. The two ends of the fabric guide roller are fixed on the machine, generally fixed by bearings, and the rotation drives or passively rotates the fabric so that it can be conveyed in a certain direction. The outer surface of the existing cloth guide roller is a horizontal straight line along the axial direction, and the cloth must pass through mechanisms such as edge suction devices to prevent wrinkles or unevenness of the cloth surface. In order to actively cor...

Problems solved by technology

However, this kind of fabric guide roller also has shortcomings. The roller is a hollow structure with low strength and rigidity, and is easy to deform, which affects the fabric guide effect.
