[0027] A fixing plate 26 is installed at one end edge of the top side of the bottom plate 1, and a reeling roller 27 is rotatably installed inside the fixing plate 26;

[0028] A vertical plate 28 is installed at the other end of the top side of the bottom plate 1, and a winding motor 29 is installed on one side of the vertical plate 28. A winding shaft 30 is installed at the output end of the winding motor 29, and a winding roller 31 is movably installed on the outer side of the winding shaft 30. During lamination, the film is unwound from the top side of the unwinding roller 27, passes through the bottom side of the tension roller 6 and the top side of the lower guide roller 19 respectively, and finally starts to be wound from the bottom side of the winding roller 31; during operation, in the production process of the composite film, the performance of the film is improved by compounding films of different properties together and laminating them, so a laminating device is needed. The film is unwound from the top side of the unwinding roller 27, passes through the bottom side of the tension roller 6 and the top side of the lower guide roller 19, and then slides inside the slide 21 through the movable block 23, so that the electrode The sheet 24 is on the same horizontal line as the top side of the film, and then the position of the movable block 23 is fixed by tightening the bolts 25, and then the cylinder 14 is started, and its active end pushes the mounting frame 15 to move downward, and the upper guide roller 20 gradually approaches the top side of the film. At the same time, one end of the connecting shaft 16 slides in the slide groove 21, and the electrode plate 22 moves downward with the connecting shaft 16. When the electrode plate 22 contacts the electrode sheet 24 on the top side of the movable block 23 in the slide groove 21, an electrical signal is generated and transmitted to the control panel 32. The control panel 32 controls the cylinder 14 to stop extending, indicating that the distance between the lower guide roller 19 and the upper guide roller 20 is the thickness of the film, so that the distance between the lower guide roller 19 and the upper guide roller 20 can be accurately adjusted according to the thickness of the film, thereby improving the lamination quality of the product.

[0029] Then, the heating wire 18 is turned on to heat the film passing through, and the lower guide roller 19 and the upper guide roller 20 heat the bottom and top sides of the film, so that both the top and bottom sides of the film are evenly heated, thereby improving the lamination effect and overall quality of the film.

[0030] After being heated and pressed, the film finally begins to be wound around the bottom side of the winding roller 31. The winding motor 29 is started, driving the winding shaft 30 to rotate, and the winding roller 31 outside the winding shaft 30 rotates accordingly, completing the winding operation of the composite film.

[0031] Working principle: First, the tension adjustment operation is performed. The angle between the rotating shaft 3 and the sliding rod 8 is the same as the angle between the rotating shaft 3 and the tension roller 6. When the tension of the tension roller 6 needs to be adjusted, the position of the sliding block 10 in the arc groove 9 is adjusted as needed, and then it is fixed by the locking screw 11. The drive motor 4 is started to drive the rotating shaft 3 to rotate. The rotating shaft 3 drives the tension roller 6 to move through the connecting plate 5. At the same time, the other rotating shaft 3 connected to the tension roller 6 also rotates accordingly, causing the connecting block 7 to start rotating. The sliding rod 8 slides in the arc groove 9 and gradually approaches the pressure sensor 12. When the sliding rod 8 contacts the pressure sensor 12, the pressure sensor 12 is subjected to pressure and generates an electrical signal. The pressure sensor 12 transmits the generated electrical signal to the control panel 32. The control panel 32 controls the drive motor 4 to stop rotating, thereby realizing the adjustment of the tension of the tension roller 6, ensuring the tension stability of the film during the production process, and improving product quality.

[0032] After the tension adjustment is completed, the top side of the film unwinding roller 27 is unwound, passes through the bottom side of the tension roller 6 and the top side of the lower guide roller 19, and then slides inside the slide groove 21 through the movable block 23, so that the electrode sheet 24 and the top side of the film are at the same level. Then, the position of the movable block 23 is fixed by tightening the bolt 25. Then, the cylinder 14 is started, and its active end pushes the mounting frame 15 to move downward, and the upper guide roller 20 approaches the top side of the film. At the same time, one end of the connecting shaft 16 slides in the slide groove 21, and the electrode plate 22 moves downward with the connecting shaft 16. When the electrode plate 22 contacts the electrode sheet 24 on the top side of the movable block 23 in the slide groove 21, an electrical signal is generated and transmitted to the control panel 32. The control panel 32 controls the cylinder 14 to stop extending, indicating that the distance between the lower guide roller 19 and the upper guide roller 20 is the thickness of the film, so that the distance between the lower guide roller 19 and the upper guide roller 20 can be accurately adjusted according to the thickness of the film, thereby improving the lamination quality of the product.

[0033] Then, the heating wire 18 is turned on to heat the film passing through, and the lower guide roller 19 and the upper guide roller 20 heat the bottom and top sides of the film, so that both the top and bottom sides of the film are evenly heated, thereby improving the lamination effect and overall quality of the film.

[0034] After being heated and pressed, the film finally begins to be wound around the bottom side of the winding roller 31. The winding motor 29 is started, driving the winding shaft 30 to rotate, and the winding roller 31 outside the winding shaft 30 rotates accordingly, completing the winding operation of the composite film.
