Description

Technical Field

[0002] In the quality inspection process of pre-prepared meals, the airtightness inspection of the packaging is an important part of ensuring food quality and safety. At present, the pressure detection method is often used in the quality inspection process of pre-prepared meal products. The principle of the pressure detection method is to place the pre-prepared meal package in a sealed test cavity, and form a negative pressure in the cavity by vacuuming. The internal pressure change is recorded by the sensor. If there is a leak in the packaging bag, the pressure change will be more obvious. A normal pressure change threshold is set, and the airtightness performance of the pre-prepared meal product packaging can be judged according to the pressure change.

[0003] The traditional intermediate device is usually composed of a bracket, an electric push rod, an air source device, a pressure sensor and two mold bases. During operation, the pre-prepared food product is placed in the mold base, the electric push rod is used to close the mold, and then the air source device is used to draw a vacuum and perform pressure testing. Since the packaging models of pre-prepared food products are various, in the process of testing multiple groups of pre-prepared food products, it is necessary to ensure that the lower mold base and the upper mold base are adapted to the product appearance. Therefore, the quality inspection process often requires the replacement of the adapted model mold base. The mold base is mainly fixed to the output end position of the bracket and the electric push rod by screws. The disassembly and assembly process is extremely inconvenient and the operating space is also small. Therefore, when the pre-prepared food products for quality inspection are various, the time for replacing the mold base is long, the quality inspection operation is inconvenient, and it cannot meet the use requirements.
