[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 1-4As shown, a laminating device for packaging box production includes a frame 1, with a conveyor belt 2 mounted above the frame 1. Further details are provided: the conveyor belt 2 has multiple T-shaped partitions spaced along its outer periphery. The partitions allow for easy placement of workpieces to be laminated. Additionally, a groove is formed on the upper part of the long side of each partition. When the workpiece is conveyed by the conveyor belt 2 to a position near the cutting component 9, this groove facilitates the cutting action. The device is simple and convenient to operate, and highly functional. Furthermore, a limiting component 3 is provided on the outer side of the conveyor belt 2 to restrict the placement of the workpiece and prevent it from... A film-carrying roller 4 is positioned above the frame 1 to support the film material, facilitating subsequent film loading. Below the film-carrying roller 4, a guide assembly 5 and a film-pressing assembly 6 are sequentially arranged on the frame 1 along the packaging box's travel direction. These components work together to ensure the film material adheres tightly to the workpiece, guaranteeing its forming quality and improving the workflow. A corner pressing assembly is located on one side of the film-carrying roller 4. This assembly presses the corners of the coated workpiece to improve its forming quality and also presses the corners at the cut edges to reduce the possibility of curling, further improving the workflow and meeting usage requirements. Furthermore, the edge and corner pressing assembly includes a longitudinal adjustment component 7, which includes a support plate 71. A slide bar 72 is positioned above the support plate 71, and a bidirectional lead screw 73 is positioned between the two slide bars 72. A movable seat 74 is positioned on the outer side of the bidirectional lead screw 73. Regarding the above arrangement: the outer circumferential threads of the two sides of the bidirectional lead screw 73 are in opposite directions. When it rotates, it drives the two movable seats 74 to move closer or further apart. The connection between the bidirectional lead screw 73 and the movable seat 74 is the same as the connection between a ball screw and a lead screw nut in the prior art, and will not be elaborated further. Relying on the established longitudinal adjustment component 7, it can adjust longitudinally... The operation of the device can drive the pressing mechanism 8 to move and adjust, which provides convenient conditions for adapting to workpieces of different specifications and sizes to carry out film coating work, greatly improving the functionality of the device. A support frame 75 is set above the moving seat 74 to ensure the film coating effect on the corners during the workpiece conveying process. At the same time, it prevents the workpiece from curling up when cutting the film. The pressing mechanism 8 is set on both sides of the support frame 75, which always presses on the workpiece, greatly reducing the possibility of curling up and ensuring the forming quality of the workpiece. A cutting component 9 is set in the middle of the corner pressing component, which cuts the film between two adjacent workpieces, reducing resource waste and ensuring the work process.

[0021] In the above process: the established corner pressing component can, on the one hand, press the corners of the coated workpiece to improve its forming quality, and on the other hand, press the corners of the coated cutting position to reduce the possibility of edge curling, thus improving the work process and meeting the usage requirements. The established limiting component 3, guiding component 5, and pressing component 6 are used. The limiting component 3 limits the placement position of the workpiece to prevent it from shifting. The guiding component 5 and pressing component 6 work together to ensure that the film adheres tightly to the workpiece, thus guaranteeing its forming quality and improving the work process. This device is reasonably designed, simple in structure, easy to process, and can improve the stability of the workpiece during transportation. It also flattens and presses the coated corners to reduce the possibility of edge curling, ensuring the forming quality of the workpiece, improving the work process, and meeting the usage requirements.

[0022] To facilitate the guidance of the film material, the guiding assembly 5 includes a first mounting sleeve 51, within which a first lifting rod 52 is disposed. Below the first lifting rod 52 is a mounting base 53, within which a guide roller 54 is disposed. A first telescopic spring 55 is fitted around the outside of the first lifting rod 52, located above the mounting base 53. Specifically, the first lifting rod 52 can be vertically adjusted relative to the first mounting sleeve 51, and there is a certain degree of damping between them. During workpiece transport, due to the workpiece thickness, the height of the guide roller 54 is raised, and the film material on the film carrier roller 4 is pressed onto the workpiece via one side of the guide roller 54. Under the action of the first telescopic spring 55, the film material can be tightly adhered to the workpiece, providing convenient conditions for subsequent film material compaction. Further, the film pressing assembly 6 includes a second mounting sleeve 61, within which a second lifting rod 62 is disposed. Below the second lifting rod 52 is a... A mounting plate 63 is provided, and a second telescopic spring 64 is sleeved on the outer side of the second lifting rod 62 located above the mounting plate 63. A pressure roller 65 is provided between the two mounting plates 63, which can be adapted to the workpiece to be processed and is used in conjunction with the pressing mechanism 8. The former presses the large area of ​​film material, and the latter presses the corners to ensure the work process. Edge trimming blades 66 are provided on the outer sides of both ends of the pressure roller 65. The working principle of how the pressure roller 65 abuts against the workpiece is the same as that of the guide roller 54. The difference is that the mounting plate 63 is placed on both sides of the conveyor belt 2, the outer side of the pressure roller 65 is close to the size of the conveyor belt 2, and the gap in the longitudinal direction of the pressing mechanism 8 is the same. The setting of the cutting blade can be freely adjusted by people according to different usage needs, especially so that the edge trimming blade 66 is flush with the two end faces of the workpiece to cut off the excess film material and ensure the forming quality of the workpiece.

[0023] To ensure the device has good functionality, the pressing mechanism 8 includes a positioning sleeve 81 connected to the support frame 75. An adjusting rod 82, set at an obtuse angle, is installed inside the positioning sleeve 81. A pressure roller 83 is installed at the lower end of the adjusting rod 82. A limit sleeve 84 is installed on the outer side of the adjusting rod 82. A compression spring 85 is installed on the outer side of the adjusting rod 82 above the limit sleeve 84. Specifically, an anti-impact plate is also installed on the outer side of the adjusting rod 82 above the positioning sleeve 81 to ensure the practicality of the device. During use, the compression spring 85 has a certain pressing effect. Under normal conditions, due to the compression spring 85, the pressure roller 83 always adheres to the top of the coated workpiece and is not prone to displacement. Simultaneously, due to the workpiece specifications, i.e., its thickness, the pressure roller 83 may be lifted to a certain height, but it will always remain pressing on the workpiece. When the workpiece coating between the two pressure rollers 83 is cut, the pressure roller 83 also remains pressing on the workpiece, greatly reducing the possibility of warping and ensuring the forming quality of the workpiece.

[0024] To cut the film material on the coated workpiece and prevent waste, the cutting assembly 9 includes a positioning plate 91 located below the support plate 71. Drive wheels 92 are positioned on both sides of the positioning plate 91, and a timing belt 93 is positioned on the outer side of the drive wheels 92. Moving plates 94 are positioned at both ends of the timing belt 93. The moving plates 94 span within the positioning plate 91 and are slidably connected to it. The two ends of the timing belt 93 are connected to the lower part of the moving plates 94, facilitating subsequent driving of the timing belt 93. A cutting blade 95 is positioned below the moving plates 94. Specifically, a drive motor is installed on the side of the positioning plate 91 near one of the drive wheels 92, which provides driving power to the drive wheels 92. The two drive wheels 92 are driven by the synchronous belt 93, which in turn acts on the moving plate 94, causing it to move and adjust the film cutting knife 95 in the longitudinal direction, thereby cutting the film-coated workpiece. Furthermore, the cutting component 9 operates in a reciprocating manner. For example, after it completes the cutting from front to back, when the next workpiece arrives at the position, the cutting component 9 moves from back to front again, thereby completing the corresponding cutting processing and meeting the usage requirements.

[0025] To further improve the rationality of the device and equipment setup, especially to ensure the stability of the workpiece during transport and reduce the possibility of deviation, the limiting component 3 includes a Z-shaped upright plate 31. A limiting wheel 32 is provided on the upper inner side of the upright plate 31. The upright plate 31 can be positioned at the middle of the conveyor belt 2 to provide a positioning location for the upright plate 31. The limiting wheel 32 rotates along the direction of the workpiece's travel and its outer circumference is attached to the outer end face of the workpiece to limit the workpiece during transport, providing convenient conditions for its smooth transport, thereby ensuring the smooth progress of the coating work and ensuring the quality of the workpiece forming.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
