Problems solved by technology

Although this kind of process has fast grinding speed and high efficiency, it has many defects: (1) There are many steps in the process, and the cost of grinding is high; (2) The rubber layer of the rolling surface is lost due to the need to reserve a turning allowance during turning The amount is large, and when the reference size of the coating roller is less than 260mm, it cannot continue to be used, which reduces the number of uses, and the turning of the defective layer is likely to cause defects such as rubber layer breakage and faults; (3) Coating after grinding is finally completed The surface roughness precision of the roller is not high, and the use effect is not ideal

Embodiment 1

[0022] Embodiment one adopts technology of the present invention to carry out grinding, and comparative effect

[0023] The first step is to roughly grind the defective roller on the grinding wheel grinder. The grinding amount is adjusted according to the thickness of the defective layer on the surface of the roller body. The rough grinding needs to grind the entire surface of the roller body flat, and defects such as scratches, depressions, and delamination are not allowed. .

[0024] In the second step, after the rough grinding of the surface of the roller is completed, enter the intermediate grinding process, fix the coating roller on the lathe, adjust the speed of the lathe to 200 rpm to rotate at a constant speed, choose GXK51-240-P-P240 for the abrasive belt, and The belt moves laterally on the surface of the rotating roller body to achieve grinding of the entire roller body. This process is repeated three times, and the surface roughness Ra of the roller body reaches 1....

Abstract

The invention discloses a coping process of a coating roller, and belongs to the technical field of rubber processing. The coping process comprises the process steps of rough grinding, medium grinding and fine grinding, wherein a wheel grinding machine is adopted to roughly grind to remove defects of scratches and indentations on the surface of the coating roller and eliminate delamination of the surface of the coating roller; a lathe and an abrasive belt are combined to perform the medium grinding and fine grinding; after the roughness of the surface of the coating roller reaches the range required in use, the coating roller is hermetically packed and warehoused. On the basis of the original process, the step of turning the defect layer by the lathe is removed, the process is simplified, the same technical effect can be realized, the requirement on the roughness of the surface of the coating roller is met, the waste of an adhesive layer is reduced, the use times of the roller body is prolonged, the maintenance cost is lowered, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber processing, in particular to a grinding process of an applicator roller. Background technique [0002] The main function of the coating roller is to apply the coating evenly on the strip. The quality of the coating roller is directly related to the surface coating quality of the strip. The precision and surface roughness of the coating roller are high. [0003] At present, with the change of the type and composition of the layer material, the improvement of the production process and the increase of production efficiency, the coating roller repaired by the traditional grinding process can no longer meet the needs of users. [0004] The applicant previously used a relatively traditional coating roller grinding process, which mainly includes turning the defective layer on a lathe, rough grinding on a grinder, intermediate grinding on an abrasive belt, and fine grinding on an abrasive belt. Among them...
