Description

Technical Field

[0001] The utility model relates to the technical field of wire mesh roller processing, in particular to an adjustable wire mesh adsorption and clamping mechanism. Background Technique

[0002] A wire mesh roller is a thin workpiece with a thickness of only dozens of microns, and patterns need to be engraved on its surface for subsequent processes. Due to its poor rigidity, it is extremely easy to deform, and it also needs to rotate during the processing, making it a challenging task to keep the processing surface in the same plane all the time. Restricted by the rigidity of the material itself, there are only workpieces with small diameters and short lengths on the market at present, so it is necessary to further expand the diversity of products.

[0003] At present, the clamping method of the wire mesh is to clamp the left and right end plates, with one side being active and the other side being driven. Since the transmission of power depends on the rigidity of the wire mesh itself, the poor performance causes a certain angular deviation between the left and right end plates, resulting in the wire mesh being twisted around the axis, and the degree of twist is related to the clamping forces on both sides. Only the method of sticking adhesive tapes on both sides can only reduce the twist and cannot completely eliminate it.

[0004] In view of the above defects, the designer actively conducts research and innovation to create an adjustable wire mesh adsorption and clamping mechanism, making it more valuable in industry. Content of the Utility Model
