Description

Technical Field

[0001] This utility model relates to the field of packaging paper technology, specifically to a paper bag processing and laminating device. Background Technology

[0002] Packaging paper refers to paper used for packaging. It is characterized by high strength, low moisture content, low air permeability, non-corrosiveness, and a certain degree of water resistance. It is also aesthetically pleasing. Paper used for food packaging must also be hygienic, sterile, and free of contaminants and impurities. In order to improve the service life of packaging paper, it is usually laminated during the production and processing process.

[0003] According to announcement number CN217258396U, a packaging paper bag laminating device is disclosed, including a base, a laminating component on one side of the top of the base, a movable frame on the top of the base, a cleaning component and an adhesion component inside the movable frame, and an output component on the other side of the top of the base. The adhesion component includes a U-shaped frame slidably connected between the front and back sides of the inner wall of the movable frame. The packaging paper bag laminating device provided by this utility model uses a compression spring in the adhesion component to compress the U-shaped frame, causing the U-shaped frame to move downwards. This, in turn, drives the adhesion roller downwards. The downward movement of the adhesion roller ensures that it fully adsorbs dust onto the side of the packaging paper to be laminated, preventing air bubbles during subsequent lamination. Furthermore, the cleaning component cleans the packaging paper before dust adhesion, further improving the integrity and smoothness of subsequent lamination.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, it is found that while the aforementioned equipment can solve the problem of inconvenience in cleaning packaging paper, resulting in a large number of air bubbles during the lamination process, which seriously reduces the lamination effect, the existing processing methods usually require manual dust removal, which is time-consuming and labor-intensive, and seriously increases the labor intensity of workers. However, during use, a lot of dust will accumulate on the surface of the adhesive roller after long-term use, which will reduce its adsorption capacity. The adhesive roller needs to be replaced or cleaned. Since the adhesive roller lacks a convenient replacement structure, the operation of replacing or cleaning the adhesive roller is cumbersome for the staff, which not only increases the maintenance time, but also reduces the continuous working efficiency of the device.

[0022] Example 1 Reference Figure 1-4This is the first embodiment of the present invention, providing a paper bag processing laminating device, including a laminating device 1. The laminating device 1 includes a base 11, a laminating assembly 12, an output assembly 13, a movable frame 14, a U-shaped frame 15, a compression spring 16, and an adhesion roller 17. The laminating assembly 12 is fixedly connected to the top left side of the base 11, the output assembly 13 is fixedly installed on the top right side of the base 11, the movable frame 14 is fixedly connected to the top of the base 11, the U-shaped frame 15 is disposed on the top of the base 11, the compression spring 16 is disposed on the top of the U-shaped frame 15, one end of the compression spring 16 is fixedly connected to both sides of the top of the U-shaped frame 15, and the other end of the compression spring 16 is fixedly connected to both sides of the top of the inner wall of the movable frame 14. The adhesion roller 17 is disposed on the top of the base 11. Disassembly and replacement mechanism 2; the disassembly and replacement mechanism 2 includes disassembly and replacement grooves 21, which are opened on both sides of the bottom of the U-shaped frame 15. The inner wall of the disassembly and replacement groove 21 is movably connected to a bearing seat 22. The adhesion roller 17 is movably connected to the inner wall of the bearing seat 22. Replacement blocks 23 are movably connected to both sides of the bottom of the bearing seat 22. The replacement blocks 23 are arc-shaped. Adjustment components 24 are opened on both sides of the inner wall of the U-shaped frame 15. Limiting mechanism 3; the limiting mechanism 3 is opened on both sides of the inner wall of the movable frame 14. The adjusting component 24 includes adjusting groove 241, which is opened on both sides of the inner wall of the U-shaped frame 15. The left side of the inner wall of the adjusting groove 241 is movably connected to the bidirectional screw 242 via a bearing. The right side of the bidirectional screw 242 extends to the right side of the U-shaped frame 15. The replacement locking block 23 is threaded to both sides of the surface of the bidirectional screw 242. The right side of the bidirectional screw 242 is fixedly connected to the rotating component 243, which includes a rotating disk. 2431, the rotating disk 2431 is fixedly connected to the right side of the bidirectional screw 242. The surface of the rotating disk 2431 is provided with slots 2432, and the number of slots 2432 is set to four. The bottom front and rear sides of the U-shaped frame 15 are provided with limit grooves 4. The replacement block 23 is movably connected to the inner wall of the limit groove 4. The top sides of the U-shaped frame 15 are fixedly connected with telescopic rods 5. The top of the telescopic rods 5 is fixedly connected to the top sides of the inner wall of the movable frame 14. The compression spring 16 is sleeved on the surface of the telescopic rods 5.

[0023] Specifically, users can drive the bidirectional screw 242 by rotating the component 243 to make the replacement block 23 move closer or separate synchronously, which can conveniently complete the replacement or cleaning of the adhesion roller 17, greatly shorten maintenance time, improve the continuous working efficiency of the device, and at the same time, the cooperation between the replacement block 23 and the limiting groove 4 ensures connection stability and avoids component wear.

[0024] Furthermore, the telescopic rod 5 provides auxiliary support and guidance for the U-shaped frame 15, and works with the compression spring 16 to keep the U-shaped frame 15 and the adhesion roller 17 in a stable position. The limiting groove 4 restricts the movement range of the replacement block 23, ensuring that it moves within the specified trajectory. At this time, the replacement block 23 is in a tightened state under the action of the adjusting component 24, which firmly fixes the bearing seat 22 and the adhesion roller 17 in the disassembly and assembly groove 21, realizing the normal working positioning of the adhesion roller 17. The rotating disk 2431 and the slot 2432 work together to drive the bidirectional screw 242 to rotate, using the bidirectional screw 24... The threaded transmission characteristic of 2 causes the replacement blocks 23 on both sides to move outward synchronously along the limiting groove 4, releasing the fixing restriction on the bearing seat 22. At this time, the bearing seat 22 and the adhesive roller 17 can be removed from the disassembly groove 21 to complete the disassembly. The new adhesive roller 17 is placed in the disassembly groove 21 through the bearing seat 22. The rotating component 243 is operated in the opposite direction to drive the bidirectional screw 242 to rotate in the opposite direction, causing the replacement block 23 to move inward along the limiting groove 4 and fit against the bearing seat 22 until it is firmly fixed, completing the replacement and installation of the adhesive roller 17. Under the elastic force of the compression spring 16, the U-shaped frame drives the adhesive roller 17 to maintain stable contact with the paper bag. The telescopic rod 5 extends and retracts synchronously with the up and down movement of the U-shaped frame 15, further ensuring the stability of the movement of the U-shaped frame 15. At the same time, the limiting groove 4 continuously constrains the position of the replacement block 23 to prevent it from loosening during operation, ensuring that the overall structure returns to a stable working state.

[0025] Example 2 In the second embodiment of this utility model, the limiting mechanism 3 includes a T-shaped groove 31, which is formed on both sides of the inner wall of the movable frame 14. The inner wall of the T-shaped groove 31 is movably connected to a limiting plate 32. The inner side of the limiting plate 32 is fixedly connected to both sides of the U-shaped frame 15. Anti-jamming components 33 are movably embedded on both sides of the limiting plate 32. The anti-jamming components 33 include ball bearings 331, which are movably embedded on both sides of the limiting plate 32. Sliding grooves 332 are formed on both sides of the inner wall of the T-shaped groove 31. The surface of the ball bearings 331 is movably connected to the inner wall of the sliding groove 332.

[0026] Specifically, the T-slot 31 and the limiting plate 32 provide precise guidance for the movement of the U-shaped frame 15, preventing it from shifting or tilting during movement. This ensures that the adhesion roller 17 always maintains stable contact with the paper bag surface, guaranteeing the dust adsorption effect. At the same time, it reduces frictional resistance during movement, making the up-and-down movement of the U-shaped frame 15 smoother and preventing jamming.

[0027] Furthermore, when the compression spring 16 drives the U-shaped frame 15 to move up and down, the limiting plate 32 can only slide along the trajectory of the T-shaped groove 31, thereby strictly limiting the movement direction of the U-shaped frame 15 and preventing it from shifting laterally or tilting. The ball bearings 331 that are movably embedded on both sides of the limiting plate 32 roll in cooperation with the sliding groove 332 on the inner wall of the T-shaped groove 31, converting sliding friction into rolling friction, reducing the friction between the limiting plate 32 and the T-shaped groove 31, making the movement of the U-shaped frame 15 smoother. This ensures that the U-shaped frame 15 moves stably in the vertical direction and prevents jamming caused by friction or angular deviation, thereby ensuring the continuous and stable adsorption effect of the adhesion roller 17 on the surface of the paper bag.

[0028] Working principle: During operation, the laminating assembly 12 and output assembly 13 on the base 11 respectively perform the laminating and conveying functions of the paper bags. The compression spring 16 inside the movable frame 14 exerts downward pressure on the U-shaped frame 15, causing the adhesion roller 17 at the bottom of the U-shaped frame 15 to tightly adhere to the surface of the paper bag. The rolling of the adhesion roller 17 adsorbs dust from the laminating surface of the paper bag, preventing air bubbles from forming during subsequent laminating processes. During this process, the telescopic rod 5 at the top of the U-shaped frame 15 moves synchronously with the extension and retraction of the compression spring 16, providing auxiliary support for the U-shaped frame 15 and limiting its lateral displacement, ensuring uniform pressure from the adhesion roller 17. At the same time, the limiting mechanisms 3 on both sides of the inner wall of the movable frame 14 provide precise guidance for the up-and-down movement of the U-shaped frame 15 through the cooperation of the T-slot 31 and the limiting plate 32, preventing it from tilting. Meanwhile, the anti-jamming balls 331 on both sides of the limiting plate 32 contact the sliding groove 332, converting sliding friction into rolling friction, making the movement of the U-shaped frame 15 smoother and ensuring the stability of the adhesion roller 17 and the paper bag. When the adhesion roller 17 needs to be replaced or cleaned due to long-term use, the operator drives the bidirectional screw 242 to rotate via the rotating disk 2431 and the slot 2432. Since the replacement clip 23 is threaded onto the surface of the bidirectional screw 242 and constrained by the limiting groove 4, the rotation of the bidirectional screw 242 will cause the two arc-shaped replacement clips 23 on both sides to move outwards synchronously along the adjusting groove 241, releasing the fixation on the bearing seat 22. At this time, the bearing seat 22 and the adhesion roller 17 sleeved within it can move out of the U-shaped frame 1. 5. Remove from the bottom disassembly slot 21 to complete disassembly. When installing the new adhesive roller 17, rotate the rotating disk 2431 in the opposite direction to make the bidirectional screw 242 drive the replacement block 23 to move inward until the arc-shaped block is tightly attached to the outer wall of the bearing seat 22, and firmly fix it in the disassembly slot 21. This realizes the quick replacement of the adhesive roller 17, making the adhesive roller 17 easy to maintain, improving the continuity and quality of paper bag laminating, and solving the problem of cumbersome and inefficient replacement of the adhesive roller 17 in traditional devices.

[0029] In summary, by setting up the disassembly and replacement mechanism 2 and the limiting mechanism 3, the disassembly and replacement mechanism 2 enables the quick disassembly and replacement and stable fixation of the adhesion roller 17, facilitating the replacement or cleaning of the adhesion roller 17, significantly shortening maintenance time, and improving the continuous working efficiency of the device. Furthermore, the limiting mechanism 3 provides precise guidance for the movement of the U-shaped frame 15, ensuring that the adhesion roller 17 maintains stable contact with the paper bag surface at all times, guaranteeing the dust adsorption effect. This solves the problem that after long-term use, a large amount of dust accumulates on the surface of the adhesion roller, leading to a decrease in its adsorption capacity and requiring replacement or cleaning. Previously, due to the lack of a convenient replacement structure for the adhesion roller, the operation was cumbersome for staff when replacing or cleaning the adhesion roller, increasing maintenance time and reducing the continuous working efficiency of the device. This solution achieves the effect of easy replacement.
