[0031] The working process of the present utility model is as follows:

[0032] In use, first, the plastic film is input through the through-hole on one side of the heating box 21 and conveyed by the belt 26. And there is a hydraulic cylinder 22 arranged at the upper end of the heating box 21. The hydraulic oil inside the hydraulic cylinder 22 drives the hydraulic rod 23 to move up and down, so that the pressing plate 24 performs hot pressing operation on the plastic film, making the surface of the plastic film smoother and flatter, eliminating surface defects and flaws, and thus improving the practicality of the device to a certain extent. And there are heating rods 27 arranged at both ends inside the heating box 21 to heat the plastic film surface. At the same time, the temperature is effectively regulated by external equipment, so as to avoid the phenomenon that the plastic film turns into liquid or gas at high temperature, making the device have a wider range of use. Secondly, by fitting and connecting the plastic film with the tripod 33, the film is folded at the lower end of the tripod 33. And through the fixed connection between the tripod 33 and the positioning arm 34, as well as the connection between the tripod 33 and the positioning arm 34, the stability during operation is improved, avoiding the shaking of the tripod 33 during use from affecting the hemming effect of the film, and enhancing the practicality of the device.
