Aerosol can interval pressure withstand testing device

Abstract

The present invention relates to an aerosol can interval pressure withstand testing device which is characterized in that the device is formed by a testing box body, a pressing cylinder, a can opening pressing head, a can opening bracket, and a controller, the inner top surface of the testing box body is fixedly equipped with the pressing cylinder. The cylinder rod bottom end of the pressing cylinder is fixedly equipped with the can opening pressing head. The can opening bracket at the lower part of the can opening pressing head is horizontally and fixedly installed in the testing box body. An L-shaped liquid inlet opening is made in the can opening pressing head. The inner end of the liquid inlet is at the lower surface of the can opening pressing head, and the outer end of the liquid inlet is at the side wall of the can opening pressing head and is connected to external compressed air through a pipeline. The structural design of the aerosol can interval pressure withstand testing device is scientific and rational, the pressure increase and can opening pressing are realized by using the compressed air and a pressed air source, by using the specially designed aerosol can opening bracket and can opening pressing head, the stabilization and sealing of the can body in a pressurization process is realized, thus the aerosol can interval pressure withstand test with a high internal pressure is satisfied, the testing time is short, the efficiency is high, the operation is easy, and the device is safe and reliable.

Description

technical field [0001] The invention relates to the field of packaging detection devices, in particular to an aerosol can internal pressure resistance test device. Background technique [0002] The quality of aerosol cans is mainly manifested in pressure resistance, sealing, corrosion resistance and surface quality. The national standard GB / T25164-2010 for aerosol cans stipulates that aerosol cans for packaging containers have a caliber of 25.4mm and a burst pressure of 0MPa-6MPa. Therefore, the pressure that can be generated by the aerosol can internal pressure tester needs to reach 6MPa. The test pressure produced by the existing aerosol can internal pressure tester is usually less than 3 MPa, which cannot meet the current aerosol can internal pressure test. Moreover, most of the sealing heads of the tank mouth of existing testers are rubber sealing heads, which are prone to deformation and leakage when a large pressure is applied, which cannot meet the testing requireme...
