Description

Technical Field

[0001] The utility model relates to the technical field of friction coefficient measurement, in particular to a double-sided friction coefficient measurement structure. Background Art

[0002] The friction coefficient (dynamic friction coefficient, static friction coefficient) is a key quality indicator of packaging adaptability. Cigarette packs in different sections of the automatic packaging line of the cigarette machine need to meet the friction requirements of "printed surface to printed surface" and "printed surface to back surface" at the same time. If the friction coefficient is too large, it will cause the cigarette machine to be blocked, stuck, and material damage; if the friction coefficient is too small, it will cause material deviation, packaging dislocation and other disadvantages.

[0003] At present, friction coefficient testers are commonly used for testing. Each test can only test "printed surface to printed surface" or "printed surface to back surface", which is inefficient. Therefore, a device (structure) for testing both sides at the same time can be designed to improve the testing efficiency and effectively guide production. After one test, dust may fall on the test surface, which will affect the test of friction coefficient and the accuracy of the test. Utility Model Content
