Plate roller adjusting device and method

Abstract

The invention discloses a plate roller adjusting device and method. The plate roller adjusting device comprises a rack and a rolling wheel installed on the rack, wherein a center shaft of the roller wheel is provided with a first axial end and a second axial end; and the plate roller adjusting device further comprises an adjusting mechanism enabling a plate roller to achieve rapid alignment during secondary imprinting, wherein the adjusting mechanism is fixedly arranged at the first axial end, the adjusting mechanism comprises an edge pushing air cylinder, a rotary connector, a locking nut, an adjusting nut and a thrust bearing, the edge pushing air cylinder enables the plate roller to follow the adjusting surface of the adjusting nut during adjustment, and meanwhile the whole device can work normally in combination with the rotary connector, the thrust bearing, a bearing seat and the like. Through the mode, the plate roller adjusting device and method can achieve follow-up adjustment of the plate roller and achieve rapid alignment, the whole adjusting period can be completed within two minutes, the adjusting period is shortened, and meanwhile, loss is reduced, the production cost is reduced, the production quality and yield of a laser film are improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing production equipment, in particular to a version roller adjustment device and an adjustment method. Background technique [0002] In the production of the existing double-roller laser embossing machine, the first imprint and the second imprint are carried out by the front and rear two plate rollers. The pattern on the master plate needs to be aligned during the second embossing, and the alignment error should be less than 0.2mm. It is difficult to achieve alignment by pasting the plate. [0003] In this way, it is easy to have the problem of misalignment of the lines during the two times of lamination, resulting in relatively large alignment errors. When the alignment error exceeds the standard, the master plate must be removed and reloaded. The reloading process takes more than 2 hours, which increases the loss of materials. Contents of the invention [0004] The main technical problem to be...
