Description

Technical Field

[0001] This utility model relates to the technical field of packaging box laminating machines, specifically a packaging box laminating machine. Background Technology

[0002] Packaging box laminating machines are an indispensable piece of equipment in the modern packaging industry. They are widely used for laminating the surfaces of various packaging boxes. Through lamination, not only can the aesthetics of the product be enhanced, but also its durability and water resistance can be improved.

[0003] Currently, existing technologies typically involve manually inserting the packaging box into the heat-shrinkable plastic film, then sealing the heat-shrinkable film with a sealing machine, and finally heating the heat-shrinkable film with a heat-shrinkable machine so that it shrinks and adheres tightly to the surface of the packaging box. However, the operation of manually inserting the packaging box into the heat-shrinkable film using a combination of manual labor and a sealing machine is too inefficient, resulting in low packaging box lamination efficiency. Therefore, it is necessary to propose a packaging box lamination machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the low wrapping efficiency of heat shrink film in existing packaging box laminating machines, this utility model proposes a packaging box laminating machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a packaging box laminating machine, including a base, a conveying device is provided on the top of the base, a gap is provided in the middle of the conveying device, an feeding roller is provided near the top of the gap, a discharging roller is provided near the bottom of the gap, and a laminating mechanism is provided on the top of the conveying device near the feeding roller.

[0006] The coating mechanism includes a fixed sleeve, which is fixedly connected to the top of the conveying device. A limit guide roller is rotatably connected to the inner wall of the fixed sleeve near the feeding roller. A guide roller is rotatably connected to the inner wall of the fixed sleeve near the top of the conveying device. A hydraulic cylinder is fixedly connected to the top of the fixed sleeve. The telescopic shaft of the hydraulic cylinder passes through the inner cavity of the fixed sleeve and is fixedly connected to a pressure plate. A heat-sealing blade is fixedly connected to the bottom of the pressure plate. A stop bar is rotatably connected to one side of the fixed sleeve. A second motor is fixedly connected to the top of the fixed sleeve, and the second motor drives the stop bar to rotate.

[0007] Preferably, a bracket is fixedly connected to the side wall of the conveying device, the feeding roller is rotatably connected to the top of the bracket, and the unloading roller is rotatably connected to the bottom of the bracket.

[0008] Preferably, a crossbar is fixedly connected to the opposite side of the bracket, and a tension sensor is rotatably connected to the outer wall of the crossbar.

[0009] Preferably, a first motor is fixedly connected to the top of the base, and the first motor drives the feeding roller to rotate.

[0010] Preferably, a positioning rod is slidably connected to the top of the fixing sleeve, and one end of the positioning rod is fixedly connected to the top of the pressure plate.

[0011] Preferably, a fixing rod is fixedly connected to the top of the fixing sleeve, and one end of the stop rod is rotatably connected to one end of the fixing rod.

[0012] Preferably, one end of the stop bar passes through the side wall of the fixed rod and is fixedly connected to a first gear, a second gear meshes with one side of the first gear, and the second gear is fixedly connected to the output end of the second motor.

[0013] The advantages of this utility model are:

[0014] This invention achieves automatic wrapping of packaging boxes by passing the heat shrink film sequentially through the feeding roller, limiting guide roller, guiding guide roller, interval, and unloading roller. After the packaging box passes the interval of the conveying device, the entire packaging box is perfectly encased in the heat shrink film. Then, a stop bar blocks the heat shrink film-wrapped packaging box, and a hydraulic cylinder drives a pressure plate to press down. The pressure plate drives a heat-sealing blade to cut and heat-seal, forming a sealed packaging bag that covers the outside of the packaging box. A second motor drives the stop bar to remove the limiting effect on the packaging box, allowing the heat shrink film-wrapped packaging box to continue moving forward on the conveying device. After being pulled a certain length by the unloading roller, the heat shrink film wraps the next packaging box, thus achieving the effect of automatic wrapping of packaging boxes with heat shrink film. This solves the problem of low wrapping efficiency of heat shrink film in existing packaging box laminating machines. Attached Figure Description

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.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a packaging box laminating machine. (Refer to...) Figures 1-5 A packaging box laminating machine includes a base 1, a conveying device 2 at the top of the base 1, a gap 21 in the middle of the conveying device 2, an feeding roller 23 near the top of the gap 21, a feeding roller 24 near the bottom of the gap 21, and a laminating mechanism 3 on the top side of the conveying device 2 near the feeding roller 23. By sequentially passing the heat shrink film through the feeding roller 23, the laminating mechanism 3, the gap 21, and the feeding roller 24, the entire packaging box is completely encased in the heat shrink film after passing the gap 21 on the conveying device 2. The laminating mechanism 3 heat-seals and cuts the heat shrink film on the outside of the packaging box, thus achieving the effect of wrapping the packaging box with the heat shrink film. In practical implementation, the packaging box wrapped with the heat shrink film is guided into the heat shrink machine to achieve the laminating effect. After the shrink film is pulled a certain length by the feeding roller 24, it is used to wrap the next packaging box, thereby improving the efficiency of packaging box laminating.

[0025] The coating mechanism 3 includes a fixed sleeve 31, which is fixedly connected to the top of the conveying device 2. A limit guide roller 32 is rotatably connected to the inner wall of the fixed sleeve 31 near the feeding roller 23. A guide roller 33 is rotatably connected to the inner wall of the fixed sleeve 31 near the top of the conveying device 2. A hydraulic cylinder 34 is fixedly connected to the top of the fixed sleeve 31. The telescopic shaft of the hydraulic cylinder 34 passes through the inner cavity of the fixed sleeve 31 and is fixedly connected to a pressure plate 35. A heat sealing blade 37 is fixedly connected to the bottom of the pressure plate 35. A stop bar 39 is rotatably connected to one side of the fixed sleeve 31. A second motor 312 is fixedly connected to the top of the fixed sleeve 31. The second motor 312 drives the stop bar 39 to rotate. The heat shrink film passes through the feeding roller 23, the limiting guide roller 32, the guiding guide roller 33, the interval 21 and the unloading roller 24 in sequence. After passing the interval 21 on the conveying device 2, the packaging box is wrapped in the heat shrink film. The stop bar 39 first blocks the packaging box so that it cannot move. Then the hydraulic cylinder 34 drives the pressure plate 35 to press down. The pressure plate 35 drives the heat sealing blade 37 to cut and heat seal the three sides of the heat shrink film, so that the cut heat shrink film is sealed and wrapped around the outside of the packaging box, thereby achieving the purpose of improving the wrapping efficiency of the packaging box.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A support 22 is fixedly connected to the side wall of the conveying device 2. The feeding roller 23 is rotatably connected to the top of the support 22, and the unloading roller 24 is rotatably connected to the bottom of the support 22. A crossbar 26 is fixedly connected to the opposite side of the support 22. A tension sensor 27 is rotatably connected to the outer wall of the crossbar 26. A first motor 25 is fixedly connected to the top of the base 1. The first motor 25 drives the unloading roller 24 to rotate. After one packaging box is wrapped, the first motor 25 drives the unloading roller 24 to rotate and pull the heat shrink film to convey a distance, which facilitates the wrapping of the next packaging box. The tension sensor 27 is used to sense and adjust the conveying tension of the heat shrink film in real time to facilitate the transmission of the heat shrink film.

[0027] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5A positioning rod 36 is slidably connected to the top of the fixed sleeve 31. One end of the positioning rod 36 is fixedly connected to the top of the pressure plate 35. A fixed rod 38 is fixedly connected to the top of the fixed sleeve 31. One end of the stop rod 39 is rotatably connected to one end of the fixed rod 38. One end of the stop rod 39 passes through the side wall of the fixed rod 38 and is fixedly connected to a first gear 310. A second gear 311 is meshed on one side of the first gear 310. The second gear 311 is fixedly connected to the output end of the second motor 312. The pressure plate 35 is driven to move up and down through the hydraulic cylinder 34. The movement of the pressure plate 35 causes the positioning rod 36 to slide on the fixed sleeve 31, thereby allowing the pressure plate 35 to move up and down stably. The second motor 312 drives the second gear 311 to rotate. The second gear 311, in conjunction with the first gear 310, drives the stop rod 39 to rotate at one end of the fixed rod 38, causing the stop rod 39 to rotate and remove the restriction on the packaging box.

[0028] Working principle: In use, the heat shrink film is first passed sequentially through the feeding roller 23, the limiting guide roller 32, the guiding guide roller 33, the interval 21, and the unloading roller 24, guiding the packaging box to the conveying device 2 at the top of the base 1. After the packaging box passes the interval 21, the film covering mechanism 3 performs the heat shrink film wrapping operation on the packaging box. The heat shrink film is wrapped around the outside of the packaging box. The hydraulic cylinder 34 on the fixed sleeve 31 drives the pressure plate 35 to press down. The pressure plate 35 drives the positioning rod 36 to slide up and down to make the pressure plate 35 press down stably. The pressure plate 35 drives the heat sealing blade 37 to perform three-sided cutting and heat sealing. The cut heat shrink film is completely sealed and wrapped around the outside of the packaging box. At this time, The second motor 312 drives the second gear 311 to rotate. The second gear 311 drives the stop bar 39 to rotate at one end of the fixed rod 38 through the first gear 310. The stop bar 39 removes the limit on the packaging box. In specific implementation, the packaging box is introduced into the heat shrink machine for heat shrink processing so that the heat shrink film can be attached to the outside of the packaging box. After one packaging box is covered, the first motor 25 drives the feed roller 24 on the bracket 22 to rotate and pull the heat shrink film to convey a distance, preparing for the next packaging box to be covered. The tension sensor 27 on the crossbar 26 senses and adjusts the conveying tension of the heat shrink film in real time to facilitate the conveying of the heat shrink film.
