Description

Technical Field

[0001] This utility model relates to the field of packaging box lamination technology, specifically a lamination machine for packaging printing. Background Technology

[0002] In the packaging and printing industry, lamination is undoubtedly a crucial step. This process involves covering the surface of printed materials with a thin film, which not only significantly improves the overall quality and visual effect of the printed materials, but also effectively enhances their durability and abrasion resistance. Laminated printed materials not only have more vibrant colors and a smoother feel, but also better resist the erosion of the external environment, such as moisture, oil, and ultraviolet rays, thereby greatly extending their service life.

[0003] When existing laminating machines process products, the tension difference between the two sides of the laminating paper easily causes curling, especially when the laminating machine is laminating on one side, the tension difference between the two sides of the laminating paper is even more difficult to control, and the laminating curling phenomenon is serious.

[0004] Therefore, this utility model provides a laminating machine for packaging printing to solve the above problems. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] This utility model provides a laminating machine for packaging printing, such as... Figure 1-5 As shown, the packaging printing laminating machine includes a frame 1. Conveyors 2 are installed at both ends of the frame 1. Support rods 3 are hinged to the lower ends of the two sets of conveyors 2 and connected to the frame 1. First mounting brackets 4 are installed on the lower left side and the upper right side of the frame 1. First drive motors 5 are fixedly installed on the two sets of first mounting brackets 4. Two sets of drive rollers 6 are rotatably installed inside the two sets of first mounting brackets 4. First synchronous pulleys 7 are installed at the front end of the two sets of drive rollers 6. First synchronous belts 8 are sleeved on the two sets of first synchronous pulleys 7. The output shafts of the two sets of first drive motors 5 are connected to the two sets of drive rollers 6 installed on the two sets of first mounting brackets 4. Multiple sets of first guide rollers 9 are installed on the two sets of first mounting brackets 4. A flattening assembly is installed at the left end of the frame 1, and a roller pressing assembly is installed inside the frame 1.

[0017] In actual operation, the paper to be laminated is first placed on the conveyor 2 at the left end of the frame 1. The first drive motor 5 is started. The first drive motor 5 drives the two sets of drive rollers 6 to rotate through the first synchronous wheel 7 and the first synchronous belt 8. The film roll is placed on the two sets of drive rollers 6, which causes the film roll to unfold. The conveyor 2 transports the paper to the right. During the paper transport process, the flattening component plays a role to ensure that the paper enters the subsequent lamination process in a flat state. The paper continues to move to the right and enters the roller pressing component area in the frame 1, where the film is evenly covered on the paper surface to prevent the film from shifting or wrinkling during the lamination process.

[0018] The flattening assembly includes a second mounting bracket 10, which is fixedly mounted on the left end of the frame 1. A slide rail 11 is fixedly mounted on the second mounting bracket 10. Two sets of guide rods 12 are provided on the slide rail 11. A slide frame 13 is slidably mounted on the slide rail 11 and the two sets of guide rods 12. A pressure roller 14 is provided at the lower end of the slide frame 13. A pressure plate 15 is provided at the lower end of the slide frame 13. The pressure plate 15 is located to the right of the pressure roller 14.

[0019] When the paper moves to the right under the action of the conveyor 2, it comes into contact with the pressure roller 14 and pressure plate 15 in the flattening assembly. With the cooperation of the carriage 13 and the slide rail 11, the pressure roller 14 and pressure plate 15 perform preliminary flattening treatment on the paper to remove any small wrinkles that may exist on the paper surface. As the paper continues to move.

[0020] The pressure roller 14 and pressure plate 15 are arranged vertically parallel to the conveyor 2 located at the left end of the frame 1, and both ends of the pressure plate 15 are inclined upwards.

[0021] This design allows the pressure rollers 14 and pressure plates 15 to apply force evenly when in contact with the paper, avoiding excessive local compression or indentation. The upward tilt of the left and right ends of the pressure plates 15 also guides the paper when it enters the flattening area, allowing the paper to enter the underside of the pressure plates 15 more smoothly, further improving the flattening effect and providing a better paper base for subsequent lamination processes.

[0022] The roll forming assembly includes a mounting base 16, which is fixedly installed inside the frame 1. Two sets of coating rollers 17 are rotatably mounted on the left end of the mounting base 16. A second guide roller 18 is provided on the upper end of the mounting base 16. A second drive motor 19 is fixedly installed on the lower end of the mounting base 16. A second synchronous pulley 20 is fixedly installed on the second drive motor 19 and on one set of coating rollers 17 mounted on the lower side of the mounting base 16. A second synchronous belt 21 is sleeved on the two sets of second synchronous pulleys 20.

[0023] During the lamination process, the second drive motor 19 starts and drives a set of lamination rollers 17 on the lower side of the mounting base 16 to rotate through the transmission action of two sets of second synchronous pulleys 20 and the second synchronous belt 21. The film and paper pass between the two sets of lamination rollers 17. Since the two sets of lamination rollers 17 are rotatably mounted on the left end of the mounting base 16, the other set of lamination rollers 17 will also rotate synchronously. Then, under the squeezing action of the lamination rollers 17, the film is evenly covered on the flattened paper surface, making the lamination effect smoother and more uniform.

[0024] Multiple sets of electric telescopic rods 22 are installed at the lower end of the mounting base 16. Each telescopic end of the electric telescopic rods 22 is fixedly equipped with a cutter 23. The mounting base 16 is provided with a cut that matches the upper end of the cutter 23.

[0025] When the laminated paper continues to move to the right to the set position, multiple sets of electric telescopic rods 22 are activated simultaneously. Their telescopic ends drive the cutter 23 to move upward. The cutter 23 cuts upward along the slits in the mounting base 16 that are adapted to the upper end of the cutter 23, accurately cutting the laminated paper according to the preset size. The cut paper is then conveyed to the next process or collection area by the conveyor 2 at the right end of the frame 1, completing the entire lamination process.

[0026] Two sets of sliders 24 are slidably mounted on each of the two sets of first mounting brackets 4. The two sets of sliders 24 on the two sets of first mounting brackets 4 are symmetrically arranged front and back. Limiting rods 25 are fixedly mounted on each of the two sets of sliders 24 on the two sets of first mounting brackets 4.

[0027] The two sets of limiting rods 25 serve to limit the film roll. After the film roll is installed on the two sets of drive rollers 6, the position of the limiting rods 25 can be adjusted by sliding the slider 24 to make them fit tightly against both ends of the film roll. During the film unfolding process, it can effectively prevent the film roll from shifting axially when rotating, ensuring the stability and uniformity of film unfolding, avoiding problems such as uneven coating and wrinkles caused by film shift, further improving the coating quality, and ensuring that the entire coating process can be carried out efficiently and stably.

[0028] Working Principle: When this packaging printing laminating machine is in operation, the equipment is first started and prepared. The paper to be laminated is placed on the conveyor 2 at the left end of the frame 1. The film roll is installed on the two sets of drive rollers 6 in the two sets of first mounting frames 4. The position of the limiting rod 25 is adjusted by the sliding slider 24 so that it fits against both ends of the film roll, thus limiting its position. Then, the first drive motor 5 is started. The first drive motor 5 drives the two sets of drive rollers 6 to rotate through the first synchronous wheel 7 and the first synchronous belt 8, causing the film roll to unfold. The film is guided by the first guide roller 9 and the second guide roller 18 and passes between the two sets of laminating rollers 17. At the same time, the conveyor 2 transports the paper to be laminated to the right. During the paper transport process, the flattening component plays a role. When the paper comes into contact with the pressure roller 14 and pressure plate 15 in the flattening component, the pressure roller 14 and pressure plate 15, with the cooperation of the slide 13 and slide rail 11, perform preliminary flattening treatment on the paper, removing any small wrinkles that may exist on the paper surface. As the paper continues to move to the right and enters the roller pressing assembly area within the frame 1, the second drive motor 19 starts. Through the transmission action of two sets of second synchronous pulleys 20 and the second synchronous belt 21, it drives a set of laminating rollers 17 on the lower side of the mounting base 16 to rotate. Since the two sets of laminating rollers 17 are mounted on the left end of the mounting base 16, the other set of laminating rollers 17 rotates synchronously. The film and paper pass between the two sets of laminating rollers 17. Under the squeezing action of the laminating rollers 17, the film is evenly covered on the flattened paper surface. When the laminated paper continues to move to the right to the set position, multiple sets of electric telescopic rods 22 start simultaneously. Their telescopic ends drive the cutter 23 to move upward. The cutter 23 cuts upward along the slits in the mounting base 16 that are adapted to the upper end of the cutter 23, cutting the laminated paper according to the preset size. The cut paper is then conveyed to the next process or collection area by the conveyor 2 at the right end of the frame 1, completing the entire laminating process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
