Description

Technical Field

[0001] The present application relates to the technical field of paper cup detection, and in particular to a quality detection device for paper cups. Background Art

[0002] A paper cup is a paper container made by mechanically processing and gluing base paper (white cardboard) made from chemical wood pulp. It can be used to hold ice cream, jam and butter, as well as hot drinks and boiling water. It is one of the common daily necessities in life.

[0003] After searching, patent number CN221572055U discloses a paper cup compression resistance detection device, which includes a machine platform, a crossbeam mounted on the machine platform, a dynamometer suspended below the crossbeam, a weight hung on the hook of the dynamometer, a lifting platform located directly below the weight and used to place paper cups on the machine platform, and a force equalizing plate located between the weight and the lifting platform. The application uses the lifting platform to drive the paper cup upward to conflict with the dynamometer hook weight and force equalizing plate hung on the crossbeam until the paper cup changes, at which time the lifting platform can be stopped. At this time, the paper cup's compression resistance value can be obtained, and the force equalizing plate is used to improve the balance of the paper cup's compression resistance as much as possible, thereby improving the accuracy of the compression resistance value.

[0004] However, the device has certain deficiencies during use. For example, when testing the compression resistance of paper cups, the patent only obtains the compression resistance value of the paper cup by the conflict between the top of the paper cup and the force equalizing plate, but does not monitor the compression resistance value by the conflict between the bottom of the paper cup and the force equalizing plate, and does not test the stiffness of the cup body, resulting in insufficient test results.
