Description

Technical Field

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

[0002] Whether the thickness of plastic film is uniform is the basis for testing the various properties of the film. Obviously, if the thickness of a batch of single-layer films is uneven, it will not only affect the tensile strength and barrier properties of various parts of the film, but also affect the subsequent processing of the film. Therefore, film thickness measurement is one of the basic testing items in the film manufacturing industry.

[0003] Announcement No. CN219810418U discloses a plastic film thickness detection device. The device is designed with an upper detection plate and a lower detection plate. The upper detection plate and the lower detection plate are installed between a first fixed plate and a second fixed plate. The opposite surfaces of the upper detection plate and the lower detection plate are respectively installed with a ray receiver and a ray transmitter. When the thickness of the plastic film needs to be detected, the plastic film passes through the upper detection plate and the lower detection plate from the middle. The upper detection plate and the lower detection plate detect whether the thickness of the plastic film is consistent through the ray receiver and the ray transmitter. Multiple groups of ray receivers and ray transmitters can speed up the inspection speed. There is no need to move the ray receiver and the ray transmitter to inspect the plastic film, so that the plastic film can be fully inspected, and it is also convenient to inspect plastic films of different sizes to prevent loopholes. However, the patent still has the following problems in actual use:
