Description

Technical Field

[0001] This utility model relates to the field of plywood production testing technology, specifically a plywood production compressive strength testing device. Background Technology

[0002] In the plywood production process, compressive strength is one of the important indicators for measuring its quality. Therefore, compressive strength testing devices play an important role in plywood production.

[0003] Currently, while existing plywood compressive strength testing devices can perform basic testing functions, they still have the following drawbacks:

[0004] 1. Inconvenient Adjustment: In existing technologies, such as the patent with authorization announcement number CN218239584U, the clamping device is adjusted by manually operating the first and second operating levers to accommodate plywood of different lengths and thicknesses. This manual adjustment method is inefficient and cumbersome, making it difficult to meet the needs of rapid testing.

[0005] 2. Low fixing efficiency: For example, the patent with authorization announcement number CN216771341U adjusts the height of the pressure plate by rotating the threaded rod to achieve clamping and fixing. This mechanical adjustment is not only time-consuming, but also prone to unstable clamping due to improper operation during frequent testing, affecting the accuracy of the test results.

[0006] 3. Insufficient automation: Existing devices generally lack automation functions and rely on manual operation to complete clamping and adjustment, which not only increases labor intensity but may also lead to low detection efficiency and make it difficult to meet the high-efficiency requirements of modern production.

[0007] Therefore, we propose a device for testing the compressive strength of plywood production. Utility Model Content
