[0024] A film laminating machine for carton production includes: a workbench 1, a conveyor belt 2 is arranged at the middle position of the workbench 1, a film unwinding device and a film pressing device are arranged on both sides of the workbench 1, first vertical plates 3 are arranged on both sides of the conveyor belt 2, a film laminating tensioning device is arranged on the first vertical plates 3, the film laminating tensioning device includes a first motor 4 and a bi-directional lead screw 5, the output end of the first motor 4 is connected to the bi-directional lead screw 5, a limit block 6 is arranged at the middle position of the bi-directional lead screw 5, moving seats 7 are arranged on both sides of the limit block 6, a first sliding groove 8 and a second sliding groove 13 are arranged on the inner sides of the first vertical plates 3, a first tensioning assembly is slidably connected to the first sliding groove 8, a second tensioning assembly is slidably connected to the second sliding groove 13, the first tensioning assembly is rotatably connected to the moving seat 7, and the second tensioning assembly is rotatably connected to the moving seat 7.
[0025] Pull out the raw material film used for film laminating from the unwinding device, pass it through the first tensioning assembly and the second tensioning assembly, and then adjust the first tensioning assembly and the second tensioning assembly to make their tension adjusted to an appropriate level. The end corresponds to the film pressing device to press and laminate the cardboard raw material below it.
[0026] The moving seat 7 includes a moving seat main body 71. A first fixing block 72 is arranged on the upper part of the moving seat main body 71. Second fixing blocks 74 are arranged on both sides of the lower part of the moving seat main body 71. A first connecting seat 73 is fixedly connected to the first fixing block 72. A second connecting seat 75 is rotatably connected to the second fixing block 74. A first connecting rod 10 is rotatably connected to the first connecting seat 73. A second connecting rod 16 is rotatably connected to the second connecting seat 75.
[0027] When the moving seat main body 71 rotates along the bidirectional lead screw 5, it moves towards or close to the bidirectional lead screw 5. The first connecting rod 10 and the second connecting rod 16 are respectively used to control the distance between the first tensioning assembly and the second tensioning assembly and the bidirectional lead screw 5, so as to control the tension of the film laminating raw material.
[0028] The first tensioning assembly includes a first sliding seat 9. The first sliding seat 9 is slidably connected to the first sliding groove 8. The first sliding seat 9 is rotatably connected to the first connecting rod 10. A first extension plate 11 is arranged on the first sliding seat 9. A first tensioning roller 12 is arranged on the first extension plate 11.
[0029] When the moving seat main body 71 moves along the bidirectional lead screw 5, the first connecting rod 10 pushes the first sliding seat 9 to move along the first sliding groove 8, so that the first tensioning roller 12 moves away from or close to the center of the bidirectional lead screw 5.
[0030] The second tensioning assembly includes a second sliding seat 14. The second sliding seat 14 is slidably connected to the second sliding groove 13.

A second extension plate 17 is arranged on the second sliding seat 14. A second tensioning roller 18 is arranged on the second extension plate 17.
[0031] Since the position of the second fixing block 74 forms an angle with the second sliding groove 13, it is necessary to rotatably connect the second connecting seat 75 to the second fixing block 74 and rotatably connect the rotating part 15 to the second connecting rod 16. At this time, when the first motor 4 drives the bidirectional lead screw 5 to rotate, the second sliding seat 14 can smoothly move along the second sliding groove 13, so as to increase or shorten the distance between the tensioning rollers.

[0033] The film laminating material roll 21 unwinds raw materials from the unwinding roller 20, passes under the second tensioning roller 18 from below, then passes over the first tensioning roller 12 from above, and then passes under the second tensioning roller 18 again, and finally enters the film laminating area.
[0034] The film pressing device includes a bracket 22, a lifting push rod 23 is arranged on the bracket 22, a lifting plate 24 is arranged at the output end of the lifting push rod 23, the lifting plate 24 is slidably connected to the bracket 22, a second motor 25 is arranged on the lifting plate 24, and a film pressing roller 26 is arranged at the output end of the second motor 25, and the film pressing roller 26 is rotatably connected to the lifting plate 24.
[0035] The lifting push rod 23 drives the lifting plate 24 to slide up and down along the bracket 22. When the raw materials below pass, the lifting plate 24 descends, and the second motor 25 starts to make the film pressing roller 26 rotate. In this process, the film raw materials are attached to the cardboard and pressed tightly.
[0036] The working principle of a film laminating machine for carton production provided by the present utility model is as follows:
[0037] The raw material film for film lamination is pulled out from the unwinding device, passes through the first tensioning assembly and the second tensioning assembly, and then the first tensioning assembly and the second tensioning assembly are adjusted to make their tension degrees adjusted to appropriate levels. The end corresponds to the film pressing device, and the cardboard raw materials below are pressed tightly and laminated.
[0038] Compared with the related technology, a film laminating machine for carton production provided by the present utility model has the following beneficial effects:
[0039] After the raw material film is pulled out, the end is clamped, and the position of this end is adjusted and corresponding to the film laminating work on the cardboard surface. At this time, the first motor 4 is started, and the first tensioning assembly and the second tensioning assembly are adjusted to the tension degree of the raw material film, ensuring that the raw material film can be more tightly combined with the cardboard raw materials after being attached, and enhancing the stability after film lamination.
