The bottom of the dust collection pipes 9 is fixedly connected with a "7"-shaped dust baffle 10. The top of the workbench 1 is equipped with a film covering component on the side near the dust baffle 10.

[0026] Through the above technical solution, a workbench 1 is set as the basic support of the device, and a conveyor belt 2 on it is used to carry and transport cartons, realizing the orderly movement of cartons between various processing components. A dust removal component, a laminating component, and a roll changing component are arranged sequentially on the top of the workbench 1 to form a continuous laminating process. In the dust removal component, the mounting frame 3 provides a mounting base for each component. The telescopic rods 4 arranged opposite to each other on the top two sides of its inner wall are fitted with a first spring 5. The bottom of the telescopic rods 4 is connected to a first mounting seat 6, so that the dust removal brush 7 rotatably connected to the inner side of the first mounting seat 6 can closely fit the surface of cartons of different thicknesses under the elastic action of the telescopic rods 4 and the first spring 5.

The dust suction device 8 at the top of the mounting frame 3, through the dust suction pipe 9 that passes through the bottom of the mounting frame 3, and in conjunction with the "7"-shaped dust baffle 10 at the bottom of the dust suction pipe 9, can quickly suck up the cleaned dust and prevent the dust from scattering, ensuring the surface of the cartons is clean and providing a good foundation for subsequent laminating processing.

[0027] This utility model provides a technical solution in which the film coating assembly includes a support plate 11, a guide roller 12, a mounting plate 13, a film coating roller 16, a cutter 18, and an unwinding frame 23;

[0028] A support plate 11 is provided on the top of the workbench 1, near the dust baffle 10. The top of the support plate 11 is movably connected to the unwinding frame 23 via a roll changing assembly. A film-coated roll 24 is provided inside the unwinding frame 23. A guide roller 12 is provided on the inner side of the support plate 11 below the film-coated roll 24. A mounting plate 13 is provided on the inner side of the support plate 11 away from the dust baffle 10. A first electric telescopic rod 14 is provided on the bottom of the mounting plate 13, near the dust baffle 10. A film-coated roller 16 is provided at the bottom of the first electric telescopic rod 14.

A cutter 18 is fixedly connected to the bottom of the second electric telescopic rod 17. A roll changing assembly is provided on the top of the workbench 1, near the cutter 18.

[0029] Through the above technical solution, the support plate 11, which is set opposite to the dust baffle 10 on the top of the workbench 1, provides stable support for the laminating assembly. Its top is movably connected to the unwinding frame 23 through the roll changing assembly. The laminating roll 24 inside the unwinding frame 23 can smoothly release the laminating material. The guide roller 12 on the inner side of the support plate 11 below the laminating roll 24 can guide and straighten the released laminating material, ensuring that the laminating material remains stable during the conveying process and avoiding deviation. The mounting plate 13 on the inner side of the support plate 11 away from the dust baffle 10 provides a mounting carrier for the laminating roller 16 and the cutter 18. The first electric telescopic rod 14 on the bottom side of the mounting plate 13 near the dust baffle 10 can flexibly adjust the height of the bottom laminating roller 16, so that the laminating roller 16 can apply pressure accurately according to the thickness of the carton and tightly adhere the laminating material to the surface of the carton. The second electric telescopic rod 17 on the bottom side of the mounting plate 13 away from the dust baffle 10 drives the cutter 18 to move up and down, so that the laminating material can be cut in time after the carton is laminating, ensuring that the laminating size of each carton is accurate.

[0030] This utility model provides a technical solution in which the roll changing assembly includes a support frame 19, a rotary bearing 20, a connecting frame 21, and a limiting assembly;

[0031] A support frame 19 is provided on the top of the workbench 1, near the side of the cutter 18. A rotary bearing 20 is provided in the middle of the top of the support frame 19. The top of the rotary bearing 20 is rotatably connected to the connecting frame 21. The connecting frame 21 is set in the shape of "I". A second motor 22 is provided on the top of the connecting frame 21 above the rotary bearing 20. The inner walls on both sides of the connecting frame 21 are fixedly connected to the side of the unwinding frame 23 away from the coated roll 24. A second slot 2301 is provided on both sides of the bottom of the unwinding frame 23. A first slot 1101 is provided on the top of the support plate 11 corresponding to the second slot 2301. A limit component is provided in the second slot 2301.

[0032] The second slot 2301 is configured with an opening diameter smaller than the inner diameter, and the limiting component includes a limiting block 25, a limiting plate 26, and a second spring 27.

[0033] The top of the limiting block 25 is fixedly connected to the bottom of the limiting plate 26, the top of the limiting plate 26 is fixedly connected to the bottom of the second spring 27, the second spring 27 is fixedly connected to the top of the inner wall of the second slot 2301, the diameter of the limiting plate 26 is equal to the inner diameter of the second slot 2301, the diameter of the limiting block 25 is equal to the opening diameter of the second slot 2301, and a guide slope is provided at the front end of the limiting block 25 facing the rotation direction.

[0034] Through the above technical solution, the support frame 19, which is positioned opposite the cutter 18 on the top of the workbench 1, provides stable support for the roll changing assembly. The rotary bearing 20 in the middle of its top is rotatably connected to the I-shaped connecting frame 21. In conjunction with the second motor 22 on the top of the connecting frame 21, the connecting frame 21 can be driven to rotate. The inner walls on both sides of the connecting frame 21 are fixedly connected to the unwinding frame 23, thereby driving the unwinding frame 23 to rotate synchronously and realize the position switching of the coated roll 24. The second slots 2301 on both sides of the bottom of the unwinding frame 23 cooperate with the first slots 1101 on the top of the support plate 11. The limiting components in the second slots 2301, through the coordinated action of the limiting block 25, the limiting plate 26, and the second spring 27, when the unwinding frame 24 rotates, the unwinding frame 24 rotates. 3. When rotated to the designated position, the limiting block 25 is engaged in the first slot 1101 under the elastic force of the second spring 27, thus achieving stable positioning of the unwinding frame 23. Since the second slot 2301 is designed with an opening diameter smaller than the inner diameter, and the diameter of the limiting block 25 matches the opening diameter and the diameter of the limiting plate 26 matches the inner diameter, the limiting block 25 can be prevented from disengaging from the slot. At the same time, a guide slope is provided at the front end of the limiting block 25 facing the rotation direction. During the roll changing rotation, the guide slope will be subjected to the force of the top of the support plate 11, which will then be transmitted to the second spring 27, causing the limiting block 25 to retract into the second slot 2301 to release the limiting position. This effectively realizes the rapid replacement of the coated roll and ensures the continuity of the coating process.

[0035] The working principle of this utility model is as follows: First, the cardboard box to be laminated is placed on the conveyor belt 2 of the workbench 1. The conveyor belt 2 drives the cardboard box to pass through the dust removal component, the laminating component, and the roll changing component in sequence to complete the corresponding processing. In the dust removal component, the telescopic rod 4 and the first spring 5 on the mounting frame 3 automatically adjust the height according to the thickness of the cardboard box, so that the dust removal brush 7 is in contact with the surface of the cardboard box. The first motor 701 drives the dust removal brush 7 to rotate and sweep the dust on the surface of the cardboard box. At the same time, the dust suction device 8 on the top of the mounting frame 3 sucks in the dust through the dust suction pipe 9. The "7"-shaped dust baffle 10 prevents the dust from scattering and ensures that the surface of the cardboard box is clean.

[0036] Next, the dust-removed cartons are conveyed to the laminating assembly by conveyor belt 2. The unwinding rack 23 on the support plate 11 releases the laminating material from the laminating roll 24. The guide roller 12 guides and straightens the laminating material. The first electric telescopic rod 14 at the bottom of the mounting plate 13 adjusts the height of the laminating roller 16, so that the laminating roller 16 presses the laminating material tightly onto the surface of the carton to complete the lamination. Subsequently, the second electric telescopic rod 17 drives the cutter 18 to cut the laminating material. The laminating assembly is a mechanism on a laminating machine in the prior art, and its structure and control principle are existing in the prior art, so it will not be described here.

[0037] When the coating roll 24 is used up, the roll changing assembly starts to work. The second motor 22 on the support frame 19 drives the rotary bearing 20 to rotate the "I"-shaped connecting frame 21. The unwinding frames 23 on both sides of the connecting frame 21 rotate accordingly. When the guide slope at the front end of the limiting block 25 rotates, it is subjected to the force of the top of the support plate 11, which causes the limiting block 25 to compress the second spring 27 upward. The limiting block 25 retracts into the second slot 2301 and releases the limiting. When the new coating roll 24 rotates to the working position, the limiting block 25 is inserted into the first slot 1101 at the top of the support plate 11 under the elastic force of the second spring 27, thereby limiting and fixing the unwinding frame 23, completing the roll changing operation, and ensuring that the coating process continues.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
