Description

Technical Field

[0001] The utility model relates to the technical field of an edge pressure tester, in particular to an edge pressure tester. Background Art

[0002] Edge Crush Tester (ECT) is an instrument used to test the edge compression strength of materials such as cardboard and corrugated boxes. This test is very important for evaluating the ability of packaging materials to withstand pressure during transportation and storage.

[0003] The working principle of the edge compression tester is usually to clamp the sample between two parallel pressure plates and apply pressure perpendicular to the corrugated direction at a constant speed until the sample is compressed and damaged. The instrument will record the maximum force value at the time of failure, thereby calculating the edge compression strength.

[0004] When testing corrugated paper, the existing edge compression tester usually requires two guide blocks to clamp the corrugated paper between the two guide blocks to place the corrugated paper vertically, thereby realizing the edge compression strength test. However, due to the design of the guide blocks, the corrugated paper will be affected during the compression test. Therefore, during the test, when the pressing plates apply opposite forces to the corrugated paper so that the corrugated paper can be vertically set between the pressing plates without the force of the guide blocks, the staff needs to reach into the processing area between the pressing plates to remove the two guide blocks. If the operation is improper, the fingers may be pinched and safety problems may occur. Therefore, in order to overcome the above-mentioned shortcomings, an edge compression tester is proposed to solve the above-mentioned technical problems. Utility Model Content

Since the traction handle and the toggle piece are both set outside the working range of the extrusion seat and the movable seat, the staff does not need to put their hands into the working range of the movable seat and the extrusion seat when operating, thereby ensuring the safety during the test.
