[0018] An auxiliary bracket 6 is provided at the front end of the frame 1 near the lower end, and a threaded rod 14 is provided on the auxiliary bracket 6. A limit plate 8 is provided at the front end of the threaded rod 14, and a roller 7 is provided at the left and right ends of the upper end of the limit plate 8. A guide rod 15 is correspondingly provided below the roller 7, and one end of the guide rod 15 passes through the auxiliary bracket 6. A second support frame 9 is provided at the front end of the threaded rod 14, and the second support frame 9 is installed on the auxiliary bracket 6. A long waist round hole 10 is opened on the second support frame 9. Two first guide rollers 11 are provided at the position of the second support frame 9, and the two first guide rollers 11 are arranged according to the upper and lower position relationship, and both ends of the two first guide rollers 11 are placed in the long waist round hole 10 and fixed by bolts.

[0019] An arc-shaped bracket 16 is disposed at the front end of the auxiliary bracket 6 , and a plurality of second guide rollers 12 are sequentially disposed on the arc-shaped bracket 16 .

[0020] The first support frame 2 is provided with a limit block 27 , and the limit block 27 is provided at the upper end of the swing rod 28 .

[0021] A rubber pad is disposed on the inner wall surface of the C-shaped buckle 30 .

[0022] During use, the metal plate is transported backwards by the second guide roller 12, and passes through the first guide roller 11 and the roller 7 on the limit plate 8 in sequence. The limit plate 8 can use the first flange 14 to adjust the distance between the two limit plates 8 according to the width of the metal plate to be filmed, so as to limit the metal plate and prevent it from running off. In the process of conveying the metal plate backwards, the winding roller 25 unwinds the film downwards, and the film will continue to unwind downwards through the tensioning roller 21. When the film approaches the pressure roller 5, the two sides of the film will be guided by the guide wheels 18 on the arc-shaped guide plate 19. Traction can make the film and the metal plate merge more accurately and stably and allow the film to be covered on the metal plate. In this process, if the tension of the film is loose when it is unrolled, the cylinder 22 can be used to pull the swing rod 28 downward to move the tension roller 21 upward, and further push the film forward, so as to adjust the tension of the film. On the contrary, if the tension of the film is too tight when it is unrolled, the cylinder 22 can be used to push the swing rod 28 upward to move the tension roller 21 downward, and further reduce the support of the tension roller on the film, so as to loosen the tension of the film.

[0023] The arc guide plate 19 can be moved left and right on the first fixing rod 20 according to the width of the film to adjust the width between the two arc guide plates 19, and the arc guide plate 19 can also adjust the angle of the arc guide plate according to the actual film needs, so that the arc guide plate 19 can better fit the film for guidance.

[0024] The beneficial effects of the utility model are as follows: the utility model has a reasonable structural design and is easy to use, and can adjust the unwinding tension of the film according to actual production needs, thereby avoiding bubbles or wrinkles caused by excessive looseness of the film when the film is attached to the metal plate; the setting of the film guide device can play a guiding role at the overlapping position of the film and the metal plate, so that the film can be attached to the metal plate more accurately, thereby improving the film sticking quality of the metal plate.

[0025] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
