The bottom outer surface of the first movable rod 11 is fixedly connected to a gate-shaped seat 12, and the outer surfaces of the front and rear opposite sides of the gate-shaped seat 12 are rotatably connected to flattening rollers 13. In this embodiment, the film material to be bonded is transported to the workbench 1. When one end of the film material is transported to the bottom of the support roller, the first electric push rod 6 is turned on, and the first electric push rod 6 drives the connecting plate 7 to move downward, so that the flattening roller 13 contacts the film material. The first motor 5 is turned on, and the first motor 5 drives the forward and reverse screw rods 3 to rotate. The rotation of the forward and reverse screw rods 3 drives the threaded plate 4 to move, so that the flattening roller 13 moves to both sides. The flattening roller 13 slides on the surface of the film material and flattens the film material to both sides to prevent it from wrinkling in the horizontal position, thereby improving its quality after bonding.

[0023] The top outer surface and the bottom outer surface of the workbench 1 are fixedly connected to support frames arranged in a mirror image. The workbench 1 is hollow at the support frame. The top outer surface of the upper support frame and the bottom outer surface of the lower support frame are fixedly installed with air coolers 22. The opposite outer surfaces of the two support frames are fixedly connected with cooling pipes 23. The output ends of the two air coolers 22 are respectively fixedly connected to the interiors of the two cooling pipes 23. Several through holes are provided on the opposite outer surfaces of the two cooling pipes 23. In this embodiment, after the heat bonding is completed, the composite film passes through the cooling pipe 23, and the cold air is transported by the air cooler 22 and blown to the composite film through the through holes to quickly cool the composite film.

[0024] A second motor 17 is fixedly installed on the outer surface of the front side panel, and the output end of the second motor 17 is fixedly connected to the rotating shaft 8. Two second movable rods 14 are movably inserted on the outer surface of the support plate 10, and the top outer surfaces of the two second movable rods 14 are fixedly connected to a U-shaped frame 15. The left and right opposite outer surfaces of the U-shaped frame 15 are rotatably connected to support rollers 16. In this embodiment, the second motor 17 is turned on, and the second motor 17 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the rotating block 9 to rotate, so that the support roller 16 rotates downward to avoid the film material being unable to be transported due to the influence of the support roller.

[0025] The top outer surface of the workbench 1 is fixedly connected to a gantry 18, and a threaded rod 19 is threaded through the top outer surface of the gantry 18. The top outer surface of the threaded rod 19 is fixedly connected to a turning handle. The threaded rod 19 is rotatably connected to the outer surface of the rotating plate with a connecting frame 20. The workbench 1 is hollow at the gantry 18. The inner surface of the workbench 1 at the gantry 18 and the outer surfaces opposite to the left and right sides of the connecting frame 20 are rotatably connected to hot pressing rollers 21. Electric heating tubes are installed inside the two hot pressing rollers 21. In this embodiment, as the film material is rolled up, the hot pressing rollers 21 are heated by the electric heating tubes, and the film material passes through the hot pressing rollers 21. By turning the turning handle, the turning handle drives the threaded rod 19 to rotate, and the threaded rod 19 drives the connecting frame 20, so that the upper hot pressing roller 21 moves downward, and the two hot pressing rollers 21 are thermally bonded to the film material.

[0026] The front outer surfaces of the two vertical plates 2 are fixedly connected to a mounting plate, the bottom outer surface of the mounting plate is fixedly installed with a second electric push rod 24, the output end of the second electric push rod 24 is fixedly connected to a rotating frame, and the left and right opposite outer surfaces of the rotating frame are rotatably connected to flattening rollers 25. In this embodiment, the second electric push rod 24 is turned on, and the second electric push rod 24 drives the flattening roller 25 to move downward, so that the flattening roller 25 presses the top of the membrane material. As the membrane material is rolled up, the membrane material is in a stretched state under the action of the flattening roller 25, thereby improving its quality after bonding.

[0027] Two sliding rods are fixedly connected to the opposite outer surfaces of the two vertical plates 2, and the two threaded plates 4 are movably mounted on the outer surfaces of the two sliding rods. In this embodiment, when the forward and reverse screw rods 3 rotate, the threaded plates 4 are driven to slide on the outer surfaces of the sliding rods, preventing the threaded plates 4 from rotating with the rotation of the forward and reverse screw rods 3.

[0028] The outer surface of the first movable rod 11 is sleeved with a first spring, and the two ends of the first spring are fixedly connected to the bottom outer surface of the support plate 10 and the top outer surface of the gate-shaped seat 12 respectively. The outer surface of the second movable rod 14 is sleeved with a second spring, and the two ends of the second spring are fixedly connected to the top outer surface of the support plate 10 and the bottom outer surface of the U-shaped frame 15 respectively. In this embodiment, by arranging the first spring and the second spring, when the flattening roller 25 moves left and right or the film material moves back and forth on the surface of the support roller 16, when the friction between the flattening roller 25 or the support roller 16 and the film material is large, the first spring or the second spring can be deformed to a certain extent to avoid damage to the film material.

[0029] The flattening roller 13 rotates toward the left and right sides, and the supporting roller 16 rotates toward the front and back sides. In this embodiment, the flattening roller 13 moves to tighten the left and right sides of the membrane material. When the supporting roller 16 rotates to contact the membrane material, the membrane material is easily transported under the supporting roller 16.

[0030] Working principle: When the present invention is in use, the film material to be bonded is conveyed to the workbench 1. When one end of the film material is conveyed to the bottom of the sheet-supporting roller, the first electric push rod 6 is turned on, and the first electric push rod 6 drives the connecting plate 7 to move downward, so that the flattening roller 13 contacts the film material. The first motor 5 is turned on, and the first motor 5 drives the forward and reverse screw rods 3 to rotate. The rotation of the forward and reverse screw rods 3 drives the threaded plate 4 to move, so that the flattening roller 13 moves to both sides. The flattening roller 13 slides on the surface of the film material and flattens the film material to both sides to prevent it from wrinkling in the horizontal position, thereby improving its quality after bonding. After flattening is completed, the first electric push rod 6 retracts one end distance to provide moving space for the rotation of the flattening roller 13, and the second motor 17 is turned on. The second motor 17 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the rotating block 9 The rotation causes the support roller 16 to rotate downward, turning on the second electric push rod 24, and the second electric push rod 24 drives the flattening roller 25 to move downward, so that the flattening roller 25 presses the top of the film material. As the film material is rolled up, the film material is in a stretched state under the action of the flattening roller 25, thereby improving its quality after bonding. As the film material is rolled up, the hot pressing roller 21 is heated by the electric heating tube, and the film material passes through the hot pressing rollers 21. The handle is turned, and the handle drives the threaded rod 19 to rotate. The threaded rod 19 drives the connecting frame 20, so that the upper hot pressing roller 21 moves downward, and the two hot pressing rollers 21 are thermally bonded to the film material. After the thermal bonding is completed, the composite film passes through the cooling tube 23, and the cold air is transported by the cold air blower 22 and blown to the composite film through the through hole, so that the composite film is quickly cooled.
