Description

Technical Field

[0001] The utility model relates to the technical field of compression resistance detection equipment, in particular to a device for detecting the compression resistance of a carton. Background Art

[0002] As an indispensable part of modern logistics, packaging boxes bear the important responsibility of packaging and protecting products. Corrugated cardboard and corrugated boxes account for the largest proportion of the packaging materials we use at present. The quality of their performance directly affects the protection ability of the packaged products. Unqualified cartons may cause damage and deformation of the packaged products. Therefore, the compressive strength of the cartons is very important, and the compression testing device is needed to test the compression performance of the cartons.

[0003] In order to improve the efficiency of the compression performance test of cartons, the prior art has made many improvements to the compression performance test device of cartons, such as the patent with the publication number CN220019185U, which discloses a compression performance test device for cartons, including a workbench, a support frame is arranged on all four sides of the bottom of the workbench, a U-shaped support plate is arranged on the top of the workbench, a pressing mechanism is arranged on the bottom outer wall of the U-shaped support plate, a turntable is arranged on the top of the workbench, an L-shaped fixed plate is arranged on the top of the turntable, a limit mechanism is arranged on the upper surface of the L-shaped fixed plate, and a rotating mechanism is arranged at the bottom of the workbench. By setting the rotating mechanism, the electric telescopic rod is started to drive the transmission plate to move back and forth horizontally, the rack of the transmission plate is meshed with the fixed teeth of the driven wheel, and the driven wheel is rotated back and forth, thereby driving the turntable to rotate, so as to realize the rotation of the compression test seat with the carton installed on one side of the L-shaped fixed plate to the bottom of the pressure plate, and the next carton can be placed on another compression test seat to prepare for the next compression strength test, so as to realize the continuous test.
