Device and method for testing compressive strength of packaging carton

Abstract

The invention provides a device and a method for testing compressive strength of a packaging carton. The lower part of a sliding drive is connected with a guide rail; a sliding plate matched with theguide rail is arranged on the guide rail; a plurality of hydraulic cylinders are arranged below the sliding plate; the lower parts of the hydraulic cylinders are connected with a pressing plate; telescopic plates are arranged at the two ends of the pressing plate; a plurality of pressure sensors are arranged on the outer side of the pressing plate; a motor is arranged at the bottom of a device body; the upper part of the motor is connected with a rotating disk; sliding rails are arranged on the two sides of the rotating disk; and a telescopic device, a positioning plate and a clamping block which are cooperatively used with the sliding plate are arranged on the sliding rail. The device and the method have the following beneficial effects: the rotating disk can aim at multi-angle detectionon the compressive strength of the packaging carton, the positioning plate ensures that the carton is not liable to move, the position of the pressing plate is adjusted through the sliding plate, thetelescopic plates at the two ends of the pressing plate are enlarged when the carton with large size is detected, the hydraulic cylinders provide lower pressure, the pressure sensors are arranged on the pressing plate, the pressing plate is monitored in real time to apply pressure, the carton is stressed uniformly, and the test device can accurately detect the compressive strength of the carton.

Description

technical field [0001] The invention belongs to the technical field of packaging carton equipment, and in particular relates to a packaging carton compressive strength testing device and a testing method thereof. Background technique [0002] With the continuous development of my country's packaging industry, packaging needs to be packaged in packaging boxes. The packaging box is folded from packaging cardboard. The packaging cardboard is first cut into the required size, and then printed, grooved, and nailed. The process is finally made into packaging cartons. After the production of packaging cartons is completed, performance testing must be carried out. Compressive strength is one of them. It is necessary to assess the maximum pressure value that the carton can withstand, the protection strength of the product designed for the carton packaging, and whether the carton can withstand the stacking weight. [0003] At present, the carton anti-pressure detection devices on the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the carton anti-pressure detection devices that appear on the market are all combined with motors, frequency converters, gears and sensors, controlled by microcomputers, and finally combined with printers to print data to complete the test. The structure of the existing anti-pressure detection devices Complexity, high cost, high operational technical requirements, and when detecting cartons, the force is often uneven, which affects the performance test results of packaging cartons. Therefore, it is urgent to involve a new detection device that can solve the above technical problems
