Packaging box strength testing device and testing method

Abstract

The invention relates to the technical field of packaging box detection, in particular to a packaging box strength testing device and method.The packaging box strength testing device comprises a base, a downward-pressing detection part and a corner detection part, the downward-pressing detection part is installed on the top of the base, and the corner detection part is arranged on the downward-pressing detection part; an existing detection device has the following problems that when the detection device fixes a packaging box, the packaging box is likely to incline, and therefore the detection precision of the packaging box is likely to be affected; the detection device can only detect the longitudinal compressive strength of the packaging box and cannot detect the transverse compressive strength of the corner of the packaging box, so that the packaging box cannot be comprehensively detected; the packaging box can be clamped and limited in all directions through the four guide clamping plates, and the packaging box can be prevented from inclining, so that the detection precision of the packaging box is ensured; the longitudinal compressive strength of the packaging box and the transverse compressive strength of the corners of the packaging box can be detected at the same time, and comprehensive detection of the packaging box is facilitated.

Description

technical field [0001] The invention relates to the technical field of packing box detection, in particular to a packing box strength testing device and a testing method. Background technique [0002] When materials are transported, loaded, unloaded, and stored, they are usually stored in packing boxes. Wooden boxes and corrugated boxes are generally used for packing boxes. After the packing boxes are manufactured, their compressive strength needs to be tested so that the packing boxes have sufficient physical properties. And mechanical properties, so as to ensure the later use performance of the packing box. [0003] When the strength of the packaging box is tested, it is easy to shift due to the uneven force on the packaging box, which will decompose the downward force exerted by the detection device on the packaging box, thereby affecting the detection result.

Problems solved by technology

[0003] When the strength of the packaging box is tested, it is easy to shift due to the uneven force on the packaging box, which will decompose the downward force exerted by the detection device on the packaging box, which will affect the testing results

[0004] Aiming at the problem that the packaging box is prone to offset during detection, the existing technology has proposed a solution. The Chinese utility model patent with the publication number CN213209696U discloses a wooden packaging box compressive strength detection device. The detection device performs lifting movement through the pressure plate , can make the pressure exerted by the pressure plate equal, and can carry out longitudinal limit and fixation on the detected wooden packaging box, can ensure the stability of the position of the wooden packaging box during the compressive strength test, and avoid displacement during the detection process of the wooden packaging box. Affect the accuracy of the test results of the compressive strength of wooden packaging boxes

[0005] However, the above-mentioned packaging case detection device has the following problems: 1. The detection device manually places the packaging case on the detection platform, so the initial position of the packaging box on the detection platform cannot be positioned, and then the packaging box is placed on the upper and lower sides of the packaging box. Horizontally fixed and vertically fixed respectively, so the force on the upper and lower sides of the packaging box is uneven, and it is easy to tilt. If the packaging box in the tilted state is squeezed, it will easily affect the detection accuracy of the packaging box.

[0006] 2. The detection device exerts pressure on the packaging box through the lifting movement of the pressure plate, so it can only detect the longitudinal compressive strength of the packaging box, and cannot detect the transverse compressive strength at the corner of the packaging box, so that the packaging box cannot be fully tested. There are limitations
