Technical Field
[0001] This utility model relates to the field of packaging box lamination technology, specifically a packaging box lamination device. Background Technology
[0002] Packaging boxes are boxes used to package products, ensuring their safety during transportation and enhancing their perceived quality. After medicines or food are packaged in packaging boxes, they often need to be laminated to seal the products inside. This lamination process requires the use of laminating equipment.
[0003] A Chinese patent with authorization announcement number CN 108189475 B discloses a lamination processing equipment and packaging box processing technology. It solves the problem that the waste material removed during the packaging box lamination process is difficult to recycle and reuse, resulting in waste of raw paper and lamination materials, increasing production costs and wasting resources. This is not economical or environmentally friendly. The key point of the technical solution is that after the raw paper is formed, cut, printed, and laminated in one go, the excess lamination waste is removed and the paper is molded and folded. This invention can make full use of and recycle raw materials during production, reduce waste of resources, and is more environmentally friendly and economical.
[0004] Existing laminating equipment often fails to adhere the film completely to the surface of packaging boxes during the laminating process, leading to frequent re-lamination and poor laminating results. Therefore, a new packaging box laminating equipment is proposed to address these issues. Utility Model Content

A conveying assembly is assembled inside a heat-sealing chamber. A drive shaft and multiple driven shafts are rotatably mounted on a support frame. A first motor is mounted on the outer wall of the support frame via a base. The output shaft of the first motor is fixedly connected to the drive shaft. Rollers are fixedly fitted on the drive shaft and driven shafts. A drive sprocket is fixedly fitted on the drive shaft, and a driven sprocket is fixedly fitted on the driven shaft. A chain is fitted on both the drive sprocket and driven sprocket. A packaging box wrapped with a film moves onto the rollers. As the packaging box moves on the rollers, it gradually enters the heat-sealing chamber. Hot air is discharged from the first, second, third, fourth, and fifth exhaust vents, ensuring that the film adheres firmly to the surface of the packaging box. This achieves complete film adhesion to the surface of the packaging box, avoiding the need for re-lamination and improving the lamination effect.
[0007] Preferably, a first guide platform is mounted on the base via a bracket, and a second guide platform is mounted on the base via a bracket. A first hydraulic cylinder is mounted on the second guide platform via a fixed bracket. A first hydraulic rod is mounted on the first hydraulic cylinder, and a pusher plate is mounted on the first hydraulic rod. A groove is formed on the second guide platform, and a guide roller is rotatably mounted on the inner wall of the groove. Packaging boxes are placed on the first and second guide platforms. An mounting frame is mounted on the base, and two sets of rotating rods are rotatably mounted on the mounting frame. Film rolls are placed on the rotating rods. A knife holder is mounted on the second guide platform, and a second [unclear - possibly a component or device] is fixedly mounted on the knife holder. The system includes a hydraulic cylinder with a second hydraulic rod mounted on it. A fixing plate is mounted on the bottom side of the second hydraulic rod, and a cutting blade is mounted on the bottom side of the fixing plate. Two sets of heat-sealing plates are symmetrically mounted on the fixing plate, and heating blocks are installed inside the heat-sealing plates. The heating blocks are connected to the control panel via internal circuitry. A film is placed on the packaging box, and then the cutting blade cuts the film. The two sets of heat-sealing plates heat-seal the film at both ends of the cutting blade. Afterward, the packaging box and the film on it move onto rollers for heat sealing. This structure allows for rapid loading of packaging boxes and efficient film covering of the packaging box surface, thus improving film covering efficiency.
[0008] The advantages of this utility model are:
[0009] 1. This utility model involves moving a packaging box wrapped with a thin film onto rollers. As the packaging box moves on the rollers, it gradually enters the heat-sealing chamber. Hot air is discharged from the first, second, third, fourth, and fifth exhaust vents, ensuring that the film adheres firmly to the surface of the packaging box. This achieves complete adhesion of the film to the surface of the packaging box, avoiding the need for re-lamination and improving the lamination effect.
[0010] 2. This utility model involves covering the packaging box with a film, then cutting the film with a cutting blade. Two sets of heat-sealing plates heat-seal the film at both ends of the cutting blade. After that, the packaging box and the film on it move onto rollers for heat sealing. This structure allows for rapid loading of the packaging box and efficient film coverage on the surface of the packaging box, which is beneficial to improving the film covering efficiency.

[0018] 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 scope of protection of the present utility model.
[0019] Please see Figure 1-3As shown, a packaging box laminating device includes a base 1, a heat sealing box 2 mounted on the base 1 via a bracket, a control panel 3 mounted on the outer wall of the heat sealing box 2, a fan 4 mounted on the top plate of the heat sealing box 2 via a base, an air guide pipe 5 mounted on the fan 4, the other end of the air guide pipe 5 connected to the top plate of the heat sealing box 2, a cavity 6 formed inside the side wall of the heat sealing box 2, a heating plate 7 with a mesh structure mounted on the inner wall of the cavity 6, and the heating plate 7 connected to the control panel 3 via an internal circuit, a first exhaust vent 8 formed on the inner wall of the bottom plate of the heat sealing box 2, a second exhaust vent 9 formed on the inner wall of the top plate of the heat sealing box 2, and a third exhaust duct 10 and a fourth exhaust duct 11 symmetrically mounted on the side wall of the heat sealing box 2. The heat sealing box 2 has a fifth air vent 12 on the inner wall of the top plate, bottom plate and side plate. A support frame 13 is installed on the base 1 via a foot bracket. A conveying assembly is installed on the support frame 13. The conveying assembly is assembled inside the heat sealing box 2. A drive shaft 14 and multiple driven shafts 15 are rotatably installed on the support frame 13. A first motor 16 is installed on the outer wall of the support frame 13 via a base. The output shaft of the first motor 16 is fixedly connected to the drive shaft 14. Rollers 17 are fixedly sleeved on the drive shaft 14 and the driven shafts 15. A drive sprocket 18 is fixedly sleeved on the drive shaft 14. A driven sprocket 19 is fixedly sleeved on the driven shaft 15. A chain 20 is sleeved on both the drive sprocket 18 and the driven sprocket 19.During operation, existing laminating equipment struggles to completely adhere the film to the surface of the packaging box 35, often requiring re-lamination and resulting in poor lamination quality. The packaging box 35, wrapped in film, moves onto roller 17. The first motor 16 then rotates the drive shaft 14, which in turn drives the drive sprocket 18. The drive sprocket 18 then drives the chain 20, which in turn drives all the driven sprockets 19. In other words, one drive shaft 14 and multiple driven sprockets 19... The rotating shaft 15 drives all the rollers 17 to rotate, and the rollers 17 transport the packaging box 35. As the packaging box 35 moves on the rollers 17, it gradually enters the heat sealing chamber 2. The fan 4 operates to introduce cold air into the cavity 6. The heating plate 7 in the cavity 6 heats the cold air into hot air. Then, the hot air is discharged from the first exhaust hole 8, the second exhaust hole 9, the third exhaust pipe 10, the fourth exhaust pipe 11, and the fifth exhaust hole 12. The packaging box 35 begins to enter the heat sealing chamber 2. The first exhaust hole 8 discharges air from bottom to top onto the packaging box 35. The film on the packaging box 35 is heated and blown onto it, causing the bottom film and the film on the lower side of the packaging box 35 to adhere to the packaging box 35. Then, the packaging box 35 moves to the second air vent 9, where the second air vent 9 blows heat onto the film on the packaging box 35 from top to bottom, causing the top film and the film on the upper side of the packaging box 35 to adhere to the packaging box 35. Then, the packaging box 35 moves to the third air duct 10, where the third air duct 10 blows heat onto the film on the packaging box 35 from front to back, causing the film on the front side of the packaging box 35 to adhere to the packaging box 35. The packaging box 35 is then moved to the fourth air duct 11, where it blows heat onto the film on the box 35 from back to front, ensuring the film on the rear side of the box 35 adheres to it. Finally, the packaging box 35 moves to the fifth air vent 12, where it blows heat onto the film again, ensuring a firm bond between the film and the surface of the box 35. This achieves complete film adhesion to the surface of the box 35, avoiding the need for re-lamination and improving the lamination effect.
[0020] Please see Figure 4-5As shown, a first guide platform 21 is mounted on the base 1 via a bracket, and a second guide platform 22 is mounted on the base 1 via a bracket. A first hydraulic cylinder 23 is mounted on the second guide platform 22 via a fixed bracket. A first hydraulic rod 24 is mounted on the first hydraulic cylinder 23, and a pusher plate 25 is mounted on the first hydraulic rod 24. A groove is formed on the second guide platform 22, and a guide roller 26 is rotatably mounted on the inner wall of the groove. A packaging box 35 is placed on the first guide platform 21 and the second guide platform 22. An mounting frame 27 is mounted on the base 1, and two sets of rotating rods 28 are rotatably mounted on the mounting frame 27. A film roll 29 is placed on rod 28. A knife holder 30 is installed on the second guide table 22. A second hydraulic cylinder 31 is fixedly installed on the knife holder 30. A second hydraulic rod is installed on the second hydraulic cylinder 31. A fixing plate 32 is installed on the bottom side of the second hydraulic rod. A cutting blade 33 is installed on the bottom side of the fixing plate 32. Two sets of heat sealing plates 34 are symmetrically installed on the fixing plate 32. A heating block is installed inside the heat sealing plate 34. The heating block is connected to the control panel 3 through an internal circuit. During operation, the existing laminating equipment has difficulty in quickly feeding and laminating the packaging box 35. This results in low lamination efficiency. The packaging box 35 is placed on the first guide table 21 and then pushed onto the second guide table 22. The first hydraulic cylinder 23 operates, and the first hydraulic rod 24 moves the pusher plate 25, which pushes the packaging box 35 forward one position. The packaging box 35 is continuously fed from the first guide table 21 to the second guide table 22. The pusher plate 25 then continuously pushes the packaging box 35 forward. When the packaging box 35 reaches the film roll 29, it pulls the film off the film roll 29, and the film covers the packaging box 35. 5. Afterwards, the packaging box 35 moves below the cutting blade 33, the second hydraulic cylinder 31 operates, and the second hydraulic rod drives the fixing plate 32 to move vertically downwards. The fixing plate 32 drives the cutting blade 33 and the two sets of heat sealing plates 34 to move vertically downwards. The cutting blade 33 cuts the film, and the two sets of heat sealing plates 34 heat seal the film at both ends of the cutting blade 33. Then, the packaging box 35 and the film on it move onto the roller 17, and then heat seal the film. This structure can quickly feed the packaging box 35 and efficiently cover the surface of the packaging box 35 with film, which is beneficial to improving the film covering efficiency.
[0021] Working principle: Existing laminating equipment struggles to quickly feed and laminate packaging boxes 35, resulting in low laminating efficiency. By placing the packaging box 35 onto the first guide table 21 and then pushing it onto the second guide table 22, the first hydraulic cylinder 23 operates, and the first hydraulic rod 24 moves the pusher plate 25. The pusher plate 25 pushes the packaging box 35 forward one position. The packaging box 35 is continuously fed from the first guide table 21 to the second guide table 22, and then the pusher plate 25 continues to push the packaging box 35 forward. When the packaging box 35 reaches the film roll 29, the packaging box 35... The film is pulled out from the film roll 29 and covers the packaging box 35. Then the packaging box 35 moves under the cutting blade 33. The second hydraulic cylinder 31 operates, and the second hydraulic rod drives the fixing plate 32 to move vertically downward. The fixing plate 32 drives the cutting blade 33 and the two sets of heat sealing plates 34 to move vertically downward. The cutting blade 33 cuts the film, and the two sets of heat sealing plates 34 heat seal the film at both ends of the cutting blade 33. Then the packaging box 35 and the film on it move to the roller 17 and then heat seal the film. This structure can quickly feed the packaging box 35 and efficiently cover the surface of the packaging box 35 with film, which is beneficial to improving the film covering efficiency.Existing laminating equipment often struggles to adhere the film completely to the surface of the packaging box 35 during the laminating process, leading to frequent re-lamination and poor laminating results. The packaging box 35, wrapped in film, moves onto rollers 17. The first motor 16 then rotates the drive shaft 14, which in turn rotates the drive sprocket 18. The drive sprocket 18 then rotates the chain 20, which in turn rotates all the driven sprockets 19. This system consists of one drive shaft 14 and multiple driven shafts 19. 5 drives all rollers 17 to rotate, and rollers 17 transport the packaging box 35. As the packaging box 35 moves on rollers 17, it gradually enters the heat sealing chamber 2. The fan 4 operates, introducing cold air into the cavity 6. The heating plate 7 in the cavity 6 heats the cold air into hot air. Then, the hot air is discharged from the first exhaust hole 8, the second exhaust hole 9, the third exhaust pipe 10, the fourth exhaust pipe 11, and the fifth exhaust hole 12. The packaging box 35 begins to enter the heat sealing chamber 2. The first exhaust hole 8 blows air from bottom to top onto the packaging box 35. The film is heated and blown to adhere the bottom and lower side films of the packaging box 35 to the packaging box 35. Then, the packaging box 35 moves to the second air vent 9, where the second air vent 9 blows heat onto the film of the packaging box 35 from top to bottom, adhering the top and upper side films of the packaging box 35 to the packaging box 35. Next, the packaging box 35 moves to the third air duct 10, where the third air duct 10 blows heat onto the film of the packaging box 35 from front to back, adhering the front side film of the packaging box 35 to the packaging box. On the packaging box 35, the box is then moved to the fourth air duct 11. The fourth air duct 11 heats the film on the packaging box 35 from back to front, causing the film on the rear side of the packaging box 35 to adhere to the packaging box 35. Finally, the packaging box 35 moves to the fifth air vent 12, where the fifth air vent 12 heats the film on the packaging box 35 again, ensuring the film adheres firmly to the surface of the packaging box 35. This achieves complete adhesion of the film to the surface of the packaging box 35, avoiding the need for re-lamination and improving the lamination effect.
