[0002] As a common packaging material, cartons play a very important role in the logistics and transportation industry. In order to ensure the quality and stability of cartons, a series of test standards need to be carried out after the cartons are produced to evaluate their durability and reliability.

[0003] Among them, the waterproof performance of the carton is one of the important indicators that need to be tested. In a humid environment, the carton is often corroded by moisture, which affects its use effect and protective performance. Therefore, waterproof testing is particularly important.

[0004] Currently, one of the methods for testing the water resistance of cartons is the weight test method, which is to weigh the weight of the cardboard before and after absorbing water. This method generally involves cutting the cardboard into discs and aligning them on the testing instrument. Since the size of the cardboard disc is the same as the instrument, calibration is required during each test, which wastes time. In addition, cutting the cardboard to match the instrument in advance also wastes time and reduces efficiency.

[0005] Therefore, in order to solve the above problems, we propose a cardboard waterproof testing device for carton production. Utility Model Content
