[0021] like Figures 1 to 4 As shown, a heated laminating machine for fabric includes two vertically arranged support columns 1. The support columns 1 are square steel, and support feet are provided at the lower ends of the square steel. A first unwinding mechanism 2 and a second unwinding mechanism 3 are fixedly connected to the lower two sides of the support columns 1. The first unwinding mechanism 2 is used to unwind the film, while the second unwinding mechanism 3 is used to unwind the fabric. A winding mechanism 5 is fixedly connected to the middle of the support columns 1, and the winding mechanism 5 is located above the first unwinding mechanism 2. The fabric of the composite film is wound up by the winding mechanism 5.

[0022] A third guide roller 9 and a fourth guide roller 11 are rotatably connected to the support column 1. An electric heating roller 12 is rotatably connected to the upper end of the support column 1. A first motor 13 is fixedly connected to the upper part of the support column 1, and the output end of the first motor 13 is fixedly connected to the electric heating roller 12. That is, when the first motor 13 is working, it drives the electric heating roller 12 to rotate.

[0023] When the fabric and film are laminated without the need for adhesive spraying, the fabric and film are bonded together on the third guide roller 9 and pass together through the electrically heated roller 12 for lamination. Then they pass through the fourth guide roller 11 and are wound up on the winding mechanism 5.

[0024] A first guide roller 7 is rotatably connected to the support column 1. A second guide roller 8 is provided on one side of the support column 1. That is, the second guide roller 8 is rotatably mounted on a horizontal bar, and the end of the horizontal bar is welded to the support column 1. The second guide roller 8 is located between the first guide roller 7 and the third guide roller 9. A glue applicator 4 is provided below the second guide roller 8. The glue applicator 4 is used to apply glue to the fabric. A glue applicator roller 10 is rotatably mounted on the upper end of the glue applicator 4.

[0025] When the fabric and film are laminated and require the application of adhesive, the fabric passes through the second guide roller 8, then through the adhesive roller 10 to apply the adhesive to the fabric, then passes around the first guide roller 7, then through the third guide roller 9 to contact the film, and then passes together through the electric heating roller 12 for lamination, and then passes through the fourth guide roller 11, and is then wound up on the winding mechanism 5.

[0026] The upper end of the support column 1 is fixedly connected to the outer shell 6, and the electric heating roller 12 is located inside the outer shell 6. The outer shell 6 is set up to provide protection.

[0027] The first unwinding mechanism 2, the second unwinding mechanism 3, and the winding mechanism 5 have the same structure, all including a support plate 21 fixed to the side wall of the support column 1. The support plate 21 is fixedly connected to the support column 1 by welding.

[0028] A fixing plate 23 is fixedly connected to one of the support plates 21. The fixing plate 23 is fixedly connected to the support plate 21 by bolts and nuts. A movable shaft 22 is inserted through the fixing plate 23, that is, the movable shaft 22 can slide axially. Two protruding rings are fixedly connected to the movable shaft 22, and the two protruding rings are located on both sides of the fixing plate 23. The protruding rings are set to prevent the movable shaft 22 from slipping off the fixing rings 23. A spring 24 is set on the movable shaft 22, and the spring 24 causes the movable shaft 22 to slide to one side.

[0029] A second motor 25 is fixedly connected to another support plate 21. The motor shaft of the second motor 25 and the movable shaft 22 are coaxial. The movable shaft 22 slides towards the second motor 25 under the action of the spring 24. When installing or removing the take-up and unwinding rollers, one end of the take-up and unwinding rollers is pre-inserted into the motor shaft of the second motor 25. Then, the movable shaft 22 is pushed to compress the spring 24. When the take-up and unwinding rollers and the movable shaft 22 are coaxial, the movable shaft 22 can be released. Under the action of the spring 24, the movable shaft 22 extends into the interior of the take-up and unwinding rollers, thus realizing the installation of the take-up and unwinding rollers. Removal is the reverse operation of the above steps. During operation, the second motor 25 works to drive the take-up and unwinding rollers to rotate.

[0030] It should be noted that the above-mentioned heating method is used for lamination. If necessary, a cooling device, such as an air-cooling device, can be installed at the take-up point of the winding mechanism 5 to avoid excessive heat accumulation in the laminated fabric.
