Pressure resistance testing device for zip-top cans

Abstract

The invention discloses a pressure resistance testing device for zip-top cans. The device comprises a pressure resistance instrument; a hydraulic cylinder is fixedly connected to the center of the upper end face of the pressure resistance instrument; a hydraulic rod is fixedly connected to the bottom of the hydraulic cylinder; the lower end of the hydraulic rod penetrates and extends out of the upper side of the inner surface of the pressure resistance instrument and is fixedly connected with a pressing plate; the pressing plate is arranged in the pressure resistance instrument and movably connected with the inner wall of the pressure resistance instrument; a fixing box fixedly connected with the bottom of the pressing plate is pressed downwards, the zip-top cans stretch into an area formed among the three sets of fixing arc plates in the pressing process of the fixing box; and when the zip-top cans stretch into a preset position, a digital control platform controls a motor to work so that a rotary disc can rotate; a first arc-shaped groove in the rotary disc rotates along with the rotary disc so as to extrude a T-shaped sliding rod; and due to limiting of a second arc-shaped groove, the T-shaped sliding rod moves inwards, namely, a fixing arc plate moves inwards, so that the zip-top cans are fixed, and the problem that the personal safety of operators is endangered due to the fact that the zip-top cans are prone to flying away after being pressed is solved.

Description

technical field [0001] The invention relates to the technical field of pressure-resistant instruments, in particular to a pressure-resistant testing device for pop cans. Background technique [0002] The pressure test of the container refers to applying pressure to the container to test the ability of the container to withstand deformation. In the process of mass production of cans, it is necessary to randomly select a specified number of cans for each batch of cans for inspection. The inspection method includes appearance Inspection, pressure test, etc., use the inspection results to measure whether the production of the batch of pop cans meets the quality standards. [0003] There are generally two types of pressure tests for cans. The first is to squeeze the cans in the up and down direction to test the ability of the cans to resist deformation under the pressure in the up and down direction. The air is injected or sucked out, so that the pressure difference between the ...

AI Technical Summary

Problems solved by technology

[0005] When the above-mentioned GBN200A withstand pressure tester is used to withstand the pressure test of the cans, there are at least the following problems that have not been improved: 1. During the downward movement of the pressure plate, the vibration of the machine itself or the influence of the external environment cause deviations in the placement of the cans, so When the pressure plate is pressed down, the uneven force may cause the can to shift, which will affect the inaccuracy of the measured value; 2. During the process of inserting the hand-held pop can into the GBN200A pressure tester, the wrong operation of the test may cause the pressure plate to press down. As a result, the hand inserted into the GBN200A pressure tester will be damaged, resulting in personal injury
