Description

TECHNICAL FIELD

[0001] The application relates to the technical field of CPP film detection, and in particular to a CPP film bearing capacity detection platform. BACKGROUND

[0002] At present, CPP film, namely cast polypropylene CPP film, is also called unstretched polypropylene CPP film, and can be divided into general-purpose CPP film, aluminized CPP film and cooking-grade CPP film according to different uses. When the CPP film is processed, the bearing capacity of the CPP film needs to be considered after the CPP film is made into a packaging bag. Therefore, the bearing capacity of the CPP film needs to be detected during the production of the CPP film.

[0003] A CPP film bearing capacity detection platform is disclosed in a Chinese patent document with the publication number CN221038372U, which comprises a bottom plate and a top plate. The upper ends of the two sides of the bottom plate are each provided with a support plate, and the upper ends of the support plates are each provided with a fixed plate. The rear end of the bottom plate is provided with a box body. The lower end of the front part of the top plate is provided with a pressure detector, and the front end of the pressure detector is provided with a control panel. The lower end of the pressure detector is provided with a pressing block.

[0004] According to the related technology in the above, when the CPP film is pressed to detect the bearing capacity of the CPP film, if the bottom end of the pressing block is in the shape of a rectangular body, the surface of the CPP film is easily subjected to shearing force during the bearing capacity detection of the CPP film, which causes the CPP film to be cut, affecting the detection precision. Moreover, when the bearing capacity is detected by the above-mentioned device, the technical personnel need to place the CPP film on the two pressing plates after flattening and tightening, and the pressing plates need to be pressed against the CPP film. The technical personnel need to manually flatten and tighten the CPP film before the pressing plates are pressed against the CPP film, which is relatively cumbersome. Utility model content
