Description

Technical Field

[0001] The utility model relates to the technical field of thickness detection equipment, in particular to a plastic film thickness detection device. Background Art

[0002] Film thickness detection device, also known as film thickness gauge or film thickness tester, is an instrument specially used to measure the thickness of films, sheets, plastic sheets, aluminum foil, copper foil and other materials. The film is placed on the test bench, the measuring head contacts the surface of the film, and then the thickness of the film is calculated by the distance between the upper and lower measuring heads, or the thickness of the film is detected by the displacement process of a single measuring head;

[0003] For example, the Chinese utility model patent disclosed by publication number CN219474574U: a BOPP film thickness detection device, which is provided with a ball nut, a connecting frame, a base plate, a reciprocating screw and a servo motor. The BOPP film is placed on a rubber magnetic sheet. During the detection process, the servo motor is turned on to drive the reciprocating screw to rotate, thereby driving the ball nut and the connecting frame to move left and right, thereby driving the rubber magnetic sheet and the BOPP film to move left and right, avoiding the need for staff to manually operate the BOPP film to move left and right, thereby improving the detection efficiency. However, after the detection probe of the detector contacts the film, due to the pulling of the film, the film may have uneven stress distribution or local deformation during the stretching process, which may cause the reading of the thickness detector to fluctuate or be unstable. At the same time, due to the pressure of the detection probe on the film, the film may be directly torn after local deformation, thereby affecting the detection efficiency. Utility Model Content
