Sealing performance inspection unit for soft bag packaging system, and inspection method

Abstract

The invention discloses a sealing performance inspection unit for a soft bag packaging system, and an inspection method. The inspection unit comprises a detection groove, a vacuum pump, a top cover, a pressure sensor, a pressure gauge and an alarm system; the vacuum pump is arranged on one side of the detection groove, the top cover is arranged on the top of the detection groove, the pressure gauge is fixed on one side of the detection groove, the pressure gauge is connected with the pressure sensor, a mounting groove is formed in the inner wall of one side of the detection groove, the pressure sensor is mounted in the mounting groove, and a disassembly and assembly structure is arranged between the detection groove and the pressure sensor; an alarm system is additionally arranged in the sealing performance inspection unit for the soft bag packaging system, so that the alarm system can automatically start an alarm lamp after the sealing performance defect exists in the soft packaging bag during detection, an operator is reminded, and the operator does not need to repeatedly compare numerical values on the pressure gauge in the daily detection process, and judges whether the soft packaging bag has the sealing defect or not only by observing whether the alarm lamp is turned on or not.

Description

technical field [0001] The invention belongs to the technical field of soft bag packaging airtightness inspection, and in particular relates to an airtightness inspection unit and inspection method for a soft bag packaging system. Background technique [0002] The airtightness inspection unit of the soft bag packaging system is a mechanism for testing the airtightness of the soft bag packaging bag. It is mainly composed of a detection tank, a vacuum pump, a top cover and a pressure sensor. Then start the vacuum pump to evacuate the tank, and wait for a certain period of time to observe whether the index of the pressure sensor changes, so as to judge whether there is air leakage in the flexible packaging bag. [0003] The existing airtightness inspection unit of the soft bag packaging system is not highly automated when in use, and the operator needs to identify and compare the index of the pressure gauge every time to judge whether the airtightness of the soft bag is good, w...

AI Technical Summary

Problems solved by technology

[0003] When the existing airtightness inspection unit of the soft bag packaging system is in use, the degree of automation is not high, and the operator needs to identify and compare the index of the pressure gauge every time to judge whether the airtightness of the soft bag is good, which has disadvantages. The existing method of opening the top cover is relatively cumbersome, which is not conducive to the operator to perform airtightness inspection on a large number of flexible packaging bags. Therefore, the present invention proposes a airtightness inspection unit and inspection method for the flexible bag packaging system
