Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a disc-type peeling test device. Background Technology

[0002] The disc peel tester is suitable for testing the adhesion of ink layers in plastic films and cellophane decorative printed materials produced by gravure printing.

[0003] However, existing peeling test devices have the following problems due to structural limitations:

[0004] 1. The rotation drive part adopts a synchronous belt drive structure design. Long-term wear of the synchronous belt leads to a decrease in transmission efficiency and transmission accuracy cannot be guaranteed. In addition, it requires regular maintenance.

[0005] 2. The linear drive section adopts a cylinder-driven structure design. The accuracy of linear movement is affected by the stability of air pressure, which affects the stability of the clamping force between the discs and cannot meet the requirements of high-precision testing scenarios.
