Description

Technical Field

[0001] The utility model relates to the technical field of drop testing, in particular to a drop testing device for a paper packaging product. Background Art

[0002] Common paper packaging products include cartons, paper boxes, paper bags, etc. Among them, cartons and paper boxes need to be subjected to drop tests after production to detect the anti-fall ability of the cartons or paper boxes, and then to check whether the quality of the cartons or paper boxes can meet the hardness requirements in applications such as transportation. In the prior art, a test stand is usually used to perform a drop test on a carton placed on a stand;

[0003] For example, the patent with publication number CN210322243U discloses a carton drop tester, specifically, the pressure valve is connected to the hand valves of two test components through the air pipe to supply air, and the two air pipe tees of each test component are connected to the hand valves through the branch air pipe, so that the carton is placed on the test movable plate above the two test components, and the air intake direction is controlled. When the gas enters the two cylinders from the upper air pipe tees, the piston ends of the two cylinders can drop, and the piston ends of the two cylinders pull the test movable plate to rotate toward the base, and the carton falls on the base to complete the test;

[0004] However, it is not possible to flexibly change the test conditions. When testing the quality of cartons, it is usually necessary to change the test parameters and perform extreme tests on the cartons to detect whether the cartons can meet the drop resistance quality during actual transportation applications. However, only using the lifting method cannot quickly detect the extreme drop of the cartons.

[0005] Based on the above description, there is an urgent need for a drop test device that can efficiently and flexibly detect the quality of paper packaging products. Utility Model Content
