Calender for preparing aramid fiber calendered product with uniform thickness

Abstract

The invention discloses a uniform-thickness calender for preparing aramid fiber calendered products, and particularly relates to the technical field of calenders, the uniform-thickness calender comprises an equipment box, the inner wall of the equipment box is connected with a transmission lead screw, and the outer wall of the transmission lead screw is provided with a supporting mechanism; the supporting assembly comprises a first threaded lantern ring block arranged on the outer wall of the transmission lead screw, and one side of the first threaded lantern ring block is connected with a second threaded lantern ring block. A first threaded lantern ring block of the supporting mechanism drives a lantern ring supporting block to move, a transverse supporting plate drives two arc-shaped concave plates to move upwards, a sleeving shaft ring can drive a ball to extrude upwards and be attached to the lower position of the outer wall of a rolling wheel, the effect of supporting the rolling wheel is achieved, in this way, during pressing, the rolling wheel has better supporting performance, and the rolling effect is improved. And uniform supporting is achieved, so that rotation damage caused by excessive extrusion on the left side and the right side is avoided, and the aramid paper is more uniform in thickness and better in uniformity during calendering.

Description

technical field [0001] The present invention relates to the technical field of calendering machines, and more particularly, the present invention relates to a calendering machine for preparing aramid calendered products with uniform thickness. Background technique [0002] Aramid paper is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus and high temperature resistance, acid and alkali resistance, light weight, insulation, anti-aging, and long life cycle. It is widely used in composite materials. A calender is required for compaction during production. [0003] Patent application publication number CN206828858U discloses a calender extrusion device for composite fabrics, including a frame, a first beam, a second beam, an upper bearing seat, a lower bearing seat, an upper roller, a lower roller, a bearing, The first hydraulic rod and the second hydraulic rod, the upper roller is installed on the front of the upper bea...

AI Technical Summary

Problems solved by technology

[0004] Based on the above patents, during calendering, the shafts on both sides of the rollers will be pressed downwards. In order to ensure the rotation of the shafts, there will be a certain rotation gap with the support point, so that the long-term downward movement will make the rollers The force is large, so there is a lot of wear when moving down, which will cause the calendering roller to shake from side to side in the later stage, and the calendering uniformity is low
