Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic coating machines, in particular to a plastic coating machine with a film thickness detection mechanism. BACKGROUND

[0002] The plastic coating machine is a device specially used for plastic coating of photos and documents and other materials. Its working principle is to cover the surface of paper with plastic film through high temperature and pressure to protect the paper, which can effectively prevent the text on the paper from fading, getting wet and being damaged. The device is commonly used in schools, offices and other places where paper protection is needed.

[0003] When the traditional plastic coating machine is used, the thickness of the protective film directly affects the pressure adjustment of the pressure roller of the plastic coating machine. If the thickness of the protective film is too large, the contact between the pressure roller and the protective film will not be tight enough. Therefore, the thickness of the protective film needs to be determined when the plastic coating machine is used. Therefore, we propose a plastic coating machine with a film thickness detection mechanism to improve the above problems. SUMMARY

[0004] The purpose of the present application is to provide a plastic coating machine with a film thickness detection mechanism to solve the problem of tight contact between the pressure roller and the protective film mentioned in the background.

[0008] As a further technical scheme of the present application, the cross section of the lifting frame is smaller than the cross section of the fixed frame, and a guide structure is formed between the lifting frame and the fixed frame.

[0009] As a further technical scheme of the present application, the cross section of the measuring rod is smaller than the cross section of the over-molding box, and a guide structure is formed between the measuring rod and the over-molding box.

[0010] As a further technical scheme of the present application, the first telescopic cylinder is provided in two groups, and the two groups of the first telescopic cylinder are symmetrically distributed about the central axis of the lifting frame.

[0011] As a further technical scheme of the present application, mounting plates are fixed to the front and rear ends of one side of the over-molding box, second telescopic cylinders are mounted to one end of the mounting plates, limit blocks are mounted to one end of the second telescopic cylinders, lower guide blocks are mounted to the bottom end of one end of the limit blocks, grooves are provided at the top end of the limit blocks, threaded rods are mounted in the grooves, and upper guide blocks are threadedly connected to the outer side wall of the threaded rods.

[0012] As a further technical scheme of the present application, the limit blocks are provided in two groups, and the two groups of the limit blocks form a telescopic mechanism through the second telescopic cylinders.

[0014] By providing the first telescopic cylinder, the lifting frame, the first scale line, and the measuring rod, the protective film thickness can be measured by the measuring box, and the distance between the upper electric heating roller and the lower electric heating roller can be adjusted, so that the upper electric heating roller and the lower electric heating roller can adapt to the over-molding work of different protective films, the over-molding machine has adjustability, and the adaptability of the over-molding machine is greatly increased.
