Description

Technical Field

[0001] This utility model relates to the field of packaging carton production technology, specifically a packaging carton laminating device. Background Technology

[0002] As an important component of modern logistics and commodity packaging, the surface lamination treatment of cardboard boxes plays a crucial role in improving their moisture resistance, abrasion resistance, and aesthetic appeal. With the continuous development of automated production technology, cardboard box lamination equipment is also constantly being upgraded and improved to meet the market's demand for efficient and high-quality packaging.

[0003] Significant progress has been made in the field of packaging carton laminating equipment. Traditional laminating methods mostly rely on manual or semi-automatic equipment, resulting in low production efficiency and inconsistent laminating quality. With the improvement of industrial automation, fully automated laminating equipment is gradually becoming more widespread. These devices integrate advanced mechanical, electrical, and control technologies to achieve rapid and accurate laminating of cartons.

[0004] Despite the achievements of existing technologies, some problems and shortcomings still exist:

[0005] Complex structure and high cost: Some fully automatic laminating equipment has a complex structure and high manufacturing cost, which increases the investment burden of enterprises.

[0006] Poor flexibility: Some equipment is inadequate when adapting to cartons of different sizes and shapes, requiring frequent adjustments to equipment parameters or replacement of parts.

[0007] Unstable lamination effect: Due to the low precision of the glue application and lamination process, the lamination effect is unstable, which affects the overall quality of the carton.

[0008] High operational difficulty: Some equipment is complex to operate and requires highly skilled operators for maintenance and management. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a packaging carton laminating device.

[0010] To achieve the above objectives, this utility model adopts the following technical solution: a packaging carton laminating device, comprising a base, a movable fixing structure, a first motor, and a second motor. The two movable fixing structures are symmetrically installed on the top of the base. Two first fixing plates are symmetrically fixedly connected to the top of the base, and a second fixing plate is fixedly connected between the two first fixing plates. The first motor is fixedly connected to the side wall of one of the first fixing plates away from the other. A lead screw is fixedly connected to the drive end of the first motor, and the lead screw is threadedly connected to a movable frame. The second motor is fixedly connected to the side wall of the movable frame. Two connecting rods are arranged inside the movable frame; one connecting rod is fixedly connected to the drive end of the second motor, and the other connecting rod is fixedly connected to the movable frame. The inner wall of the moving frame is rotatably connected. A rotating disk is fixedly connected to the end of each of the two connecting rods away from the first fixed plate. A first movable rod is fixedly connected to the side wall of one of the rotating disks away from the connecting rod, and a second movable rod is fixedly connected to the side wall of the other rotating disk away from the connecting rod. One end of the first movable rod and one end of the second movable rod are respectively fixedly connected to the two ends of the fixed rod. A film-coating roller and a glue-applying roller are arranged above the base. A first connecting plate is fixedly connected to the top of the film-coating roller. A first slot is formed through the side wall of the first connecting plate, and the first movable rod is movably engaged inside the first slot. A second connecting plate is fixedly connected to the top of the glue-applying roller. A second slot is formed through the side wall of the second connecting plate, and the second movable rod is movably engaged inside the second slot.

[0011] Preferably, the movable frame is in contact with the bottom of the second fixed plate.

[0012] Preferably, both the first connecting plate and the second connecting plate are slidably engaged inside the movable frame.

[0013] Preferably, the first movable rod is fixedly connected to the eccentric part of one of the rotating disks, and the second movable rod is fixedly connected to the eccentric part of the other rotating disk, with the first and second movable rods arranged symmetrically at the center.

[0014] Preferably, the two movable fixed structures are located on both sides of the movable frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. Highly efficient automated operation: Driven by a second motor, the device enables the rotating disc to drive the first and second movable rods in a circular motion. This design cleverly utilizes mechanical principles, allowing the coating roller and the glue-applying roller to move up and down independently without the need for an additional lifting mechanism, thus simplifying the structure and improving the degree of automation.

[0017] 2. Flexible Working Mode: Due to the symmetrical arrangement of the first and second movable rods and their opposite directions of movement, this design allows the gluing roller and laminating roller to alternately contact the cardboard. When the gluing roller is applying glue, the laminating roller is positioned above and waiting; conversely, when the laminating roller is laminating, the gluing roller is positioned above. This alternating working mode not only improves work efficiency but also ensures the quality of gluing and lamination.

[0018] 3. Convenient Cardboard Handling: When the laminating roller and glue roller are at the same height and there is a large gap between them and the base, the operator can easily pick up and place the cardboard on the base. This design takes ergonomic factors into account, making the entire operation process more convenient and safer.

[0019] 4. Precise Position Adjustment: Driven by the first motor, the movable frame can move linearly in the horizontal direction. This design allows the positions of the glue coating roller and the laminating roller to be precisely adjusted according to the actual size and position of the cardboard, thereby ensuring the accuracy and consistency of glue coating and lamination.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figure 1-2As shown, this utility model embodiment provides a packaging carton laminating device, including a base 1, a movable fixing structure 2, a first motor 5, and a second motor 8. The two movable fixing structures 2 are symmetrically installed on the top of the base 1. Two first fixing plates 3 are symmetrically fixedly connected to the top of the base 1, and a second fixing plate 4 is fixedly connected between the two first fixing plates 3. The first motor 5 is fixedly connected to the side wall of one of the first fixing plates 3 away from the other. A lead screw 6 is fixedly connected to the drive end of the first motor 5, and a movable frame 7 is threaded onto the lead screw 6. The second motor 8 is fixedly connected to the side wall of the movable frame 7. Two connecting rods 9 are provided inside the movable frame 7. One connecting rod 9 is fixedly connected to the drive end of the second motor 8, and the other connecting rod 9 is rotatably connected to the inner wall of the movable frame 7. A rotating disk 10 is fixedly connected to the end away from the first fixed plate 3. A first movable rod 11 is fixedly connected to the side wall of one rotating disk 10 away from the connecting rod 9, and a second movable rod 12 is fixedly connected to the side wall of the other rotating disk 10 away from the connecting rod 9. One end of the first movable rod 11 and one end of the second movable rod 12 are fixedly connected to the two ends of the fixed rod 19, respectively. A film-coating roller 15 and a glue-applying roller 16 are arranged above the base 1. A first connecting plate 13 is fixedly connected to the top of the film-coating roller 15. A first slot 17 is opened through the side wall of the first connecting plate 13. The first movable rod 11 is movably engaged inside the first slot 17. A second connecting plate 14 is fixedly connected to the top of the glue-applying roller 16. A second slot 18 is opened through the side wall of the second connecting plate 14. The second movable rod 12 is movably engaged inside the second slot 18.

[0025] The movable frame 7 contacts the bottom of the second fixed plate 4. This design ensures the stability of the movable frame 7 during horizontal movement. The second fixed plate 4, as a support structure, provides a solid platform for the movable frame 7 at its bottom, preventing swaying or displacement caused by movement, thereby ensuring the accuracy and stability of the coating roller 16 and the laminating roller 15 during operation.

[0026] The first connecting plate 13 and the second connecting plate 14 are both slidably engaged inside the movable frame 7. This sliding engagement design allows the first connecting plate 13 and the second connecting plate 14 to move smoothly up and down inside the movable frame 7 without shifting or jamming. This design not only improves the flexibility of the mechanical structure but also ensures that the laminating roller 15 and the gluing roller 16 can be accurately adjusted to the required height to meet the processing needs of different paperboards.

[0027] The first movable rod 11 is fixedly connected to the eccentric position of one of the rotating disks 10, and the second movable rod 12 is fixedly connected to the eccentric position of the other rotating disk 10, with the two arranged symmetrically at the center. This symmetrical design is key to enabling the alternating operation of the coating roller 15 and the glue-applying roller 16. By ensuring that the first movable rod 11 and the second movable rod 12 are at the same eccentric position on the rotating disk 10 but in opposite directions, it can be ensured that they can drive the corresponding first connecting plate 13, second connecting plate 14, coating roller 15, and glue-applying roller 16 to move in opposite directions during their circular motion. This design not only simplifies the mechanical structure but also improves the stability and reliability of the motion.

[0028] Two movable fixing structures 2 are located on both sides of the movable frame 7. Arranging the movable fixing structures 2 on both sides of the movable frame 7 ensures stable fixation of the cardboard during processing. This layout prevents the cardboard from shifting or deforming during gluing and lamination, thus improving processing accuracy and product quality. Simultaneously, fixing from both sides helps balance the stress on the cardboard, avoiding twisting or tilting problems caused by fixing from only one side.

[0029] Working Principle: When using the packaging carton laminating device, the second motor 8 drives the connecting rod 9 to rotate the rotating disk 10. Since the first movable rod 11 and the second movable rod 12 are fixedly connected to the eccentric points of the two rotating disks 10, the two rotating disks 10 can respectively drive the first movable rod 11 and the second movable rod 12 to rotate circumferentially. The first movable rod 11 is engaged in the first slot 17 on the first connecting plate 13, and the second movable rod 12 is engaged in the second slot 18 on the second connecting plate 14. The first connecting plate 13 and the second connecting plate 14 are limited by the movable frame 7. When the first movable rod 11 rotates circumferentially in the first slot 17 of the first connecting plate 13, and the second movable rod 12 rotates circumferentially in the second slot 18 of the second connecting plate 14, the first movable rod 11 can drive the first connecting plate 13 to move the laminating roller 15 up and down, and the second movable rod 12 can drive the second connecting plate 14... 14 drives the glue-applying roller 16 to move up and down. Since the first movable rod 11 and the second movable rod 12 are centrally symmetrically arranged, the first movable rod 11 and the second movable rod 12 move in opposite directions. When the laminating roller 15 and the glue-applying roller 16 are at the same height, there is a large gap between the glue-applying roller 15 and the base 1, which makes it easy for the operator to pick up and put the cardboard on the base 1. After the operator places the cardboard on the base 1, the two ends of the cardboard are clamped and fixed by the two movable fixing structures 2. Then, the second motor 8 drives the glue-applying roller 16 to move downward, so that the glue-applying roller 16 contacts the cardboard, so that the glue-applying roller 16 can apply glue to the cardboard. When the glue-applying roller 16 applies glue to the cardboard on the base 1, the laminating roller 15 is located above the cardboard. After the cardboard is submitted, the second motor 8 drives the laminating roller 15 to contact the cardboard. When the laminating roller 15 applies film to the cardboard, the glue-applying roller 16 is located above the cardboard. Then, the first motor 5 can drive the lead screw 6 to move the movable frame 7 horizontally and linearly, so that the position of the laminating roller 15 and the glue coating roller 16 on the movable frame 7 can be changed, so that the laminating roller 15 and the glue coating roller 16 can coat and laminate the entire paperboard.

[0030] 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.
