Description

Technical Field

[0001] This utility model belongs to the technical field of laminating equipment, and in particular relates to a laminating equipment for food packaging paper production. Background Technology

[0002] Laminating equipment for food packaging paper production is a specialized machine used to laminate a thin film onto the surface of food packaging paper. Its core function is to use a specific process to tightly bond plastic film or other functional films to the base paper of the food packaging, forming a composite packaging material that combines the stiffness of paper with the barrier properties of film. This equipment must strictly adhere to food contact material safety standards to ensure that no harmful substances migrate during the laminating process, ultimately improving the durability, sealing, and freshness preservation capabilities of the food packaging paper, and meeting the safety and functional requirements of food packaging.

[0003] However, existing packaging paper laminating methods are not convenient for disassembling the take-up rollers during use, making the replacement of the take-up rollers very cumbersome. This not only consumes a lot of manual operation time, but also easily causes short-term equipment shutdowns due to improper disassembly and assembly, ultimately reducing the overall working efficiency of packaging paper laminating. Utility Model Content

[0004] The purpose of this utility model is to provide a laminating equipment for food packaging paper production. By setting up a disassembly part, it solves the problem that it is inconvenient to disassemble the take-up roller, making the replacement of the take-up roller very cumbersome. This not only consumes a lot of manual operation time, but also easily causes short-term equipment shutdown due to improper disassembly and assembly, ultimately reducing the overall working efficiency of packaging paper laminating.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a laminating device for food packaging paper production, comprising a workbench and further comprising: a disassembly section disposed on the top of the workbench; a laminating section disposed on the top of the workbench; the disassembly section comprising a disassembly assembly disposed on the top of the workbench; and a drive assembly disposed on the disassembly assembly; the disassembly assembly comprising a support plate fixedly connected to the top of the workbench, a rotating shaft rotatably connected to the support plate, a limit sleeve fixedly connected to the outer wall of the rotating shaft, a take-up roller slidably connected to the outer wall of the limit sleeve, packaging paper wound around the outer wall of the take-up roller, a hydraulic push rod fixedly connected to the top of the workbench, a support block fixedly connected to the output end of the hydraulic push rod, and the outer wall of the rotating shaft contacting the support block.

[0006] Furthermore, the coating section includes a coating assembly mounted on top of the worktable; and a configuration assembly mounted on top of the worktable.

[0007] Furthermore, the drive assembly includes a motor sleeve fixedly connected to a support plate, a motor fixedly connected to the motor sleeve, and the output shaft of the motor fixedly connected to a rotating shaft via a coupling. The motor is located on the left side of the support plate.

[0008] Furthermore, the laminating assembly includes two support plates fixedly connected to the top of the workbench, with a film roll rotatably connected to each of the two support plates. Two legs are fixedly connected to the top of the workbench, and a glue storage tank is fixedly connected to one side of the two legs that are close to each other. A discharging device is provided on the glue storage tank, and the film roll contacts the packaging paper. The discharging device includes several feeding pipes fixedly connected to the bottom of the glue storage tank. Each of the feeding pipes is equipped with a solenoid valve, and a uniform glue outlet is fixedly connected to the bottom of the feeding pipes. The uniform glue outlet is located at the top of the packaging paper.

[0009] Furthermore, the configuration component includes two rectangular blocks fixedly connected to the top of the workbench. Each of the two rectangular blocks has a slide rod fixedly connected to its top. A top plate is fixedly connected to the top of each of the two slide rods. A sliding frame is slidably connected to the outer wall of each of the two slide rods. A hot press roller is rotatably connected to the sliding frame. A rotating component is provided on the top plate. The packaging paper and film roll are in contact with the hot press roller. The rotating component includes a screw threadedly connected to the top plate. A manual turntable is fixedly connected to the top of the screw. The bottom end of the screw is rotatably connected to the sliding frame.

[0010] This utility model has the following beneficial effects: 1. By setting up a disassembly section, when the winding roller is full of coated packaging paper and needs to be replaced, the hydraulic push rod is activated to drive the support block to move down, so that one end of the rotating shaft is suspended to leave operating space. The limiting sleeve on the outer wall of the rotating shaft will limit the rotational deviation of the winding roller and ensure the stability of the disassembly position. The staff can pull it down and out to complete the removal of the old roller and the installation of the new roller. This setting can simplify the replacement process, reduce downtime, and improve the efficiency of the coating operation. 2. By setting up a laminating section, during use, first extend one end of the packaging paper through the glue storage box to the film roll, and then cover the outer surface of the packaging paper with the film roll. After both are passed through the hot press roller, they are wound onto the take-up roller. Since the initial section of the packaging paper is not coated with glue, it can be cut off and discarded later. Then, the solenoid valve controls the glue feeding according to the program, and the motor starts synchronously. The motor drives the take-up roller to rotate through the shaft, so that the packaging paper passes through the glue outlet at a uniform speed and is evenly coated with glue. The glued packaging paper and the film roll are then hot-pressed and bonded by the preheated hot press roller, and finally wound onto the take-up roller. If it is necessary to adjust the tension, turn the manual turntable to drive the screw to rotate. The screw drives the slide frame and the hot press roller to move up and down with the slide rod as a guide, so as to adapt to materials of different thicknesses, ensure stable laminating tension, and avoid problems.

[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] Please see Figure 1-6As shown, this utility model is a laminating equipment for food packaging paper production, including a workbench 1, and further including: a disassembly part 2, which is disposed on the top of the workbench 1; and a laminating part 3, which is disposed on the top of the workbench 1.

[0017] The disassembly unit 2 includes a disassembly assembly 21, which is mounted on the top of the workbench 1; and a drive assembly 22, which is mounted on the disassembly assembly 21. The disassembly assembly 21 includes a support plate 211 fixedly connected to the top of the workbench 1, a rotating shaft 212 rotatably connected to the support plate 211, a limit sleeve 213 fixedly connected to the outer wall of the rotating shaft 212, a winding roller 214 slidably connected to the outer wall of the limit sleeve 213, and packaging paper 215 wound around the outer wall of the winding roller 214. A hydraulic push rod 216 is fixedly connected to the top of the workbench 1, and a support block 217 is fixedly connected to the output end of the hydraulic push rod 216. The outer wall of the rotating shaft 212 contacts the support block 217. The drive assembly 22 includes a motor sleeve 221 fixedly connected to the support plate 211, a motor 222 fixedly connected to the motor sleeve 221, and the motor 222 outputs... The output shaft is fixedly connected to the rotating shaft 212 via a coupling. The motor 222 is located on the left side of the support plate 211. By setting up the disassembly part 2, when the winding roller 214 is fully wound with the coated packaging paper 215 and needs to be replaced, the hydraulic push rod 216 can be activated first. The hydraulic push rod 216 will drive the support block 217 to move downward, so that one end of the rotating shaft 212 loses support and is suspended in the air, leaving operating space for the disassembly of the winding roller 214. At the same time, the limiting sleeve 213 on the outer wall of the rotating shaft 212 will limit the winding roller 214 to prevent it from rotating off the outer wall of the rotating shaft 212, ensuring that the position is stable during disassembly. Then, the staff only needs to pull out the winding roller 214 to quickly complete the removal of the old roller and the installation of the new roller. Through this setting, the replacement process of the winding roller can be greatly simplified, the equipment downtime can be reduced, and the overall efficiency of the packaging paper coating operation can be improved.

[0018] The coating section 3 includes a coating assembly 31, which is mounted on the top of the workbench 1;Configuration component 32 is installed on the top of workbench 1. Laminating component 31 includes two support plates 311 fixedly connected to the top of workbench 1. A film roll 312 is rotatably connected to the two support plates 311. Two legs 313 are fixedly connected to the top of workbench 1. A glue storage tank 314 is fixedly connected to the side of the two legs 313 that are close to each other. A discharge device is provided on the glue storage tank 314. The film roll 312 is in contact with the packaging paper 215. Configuration component 32 includes two rectangular blocks 321 fixedly connected to the top of workbench 1. A slide rod 322 is fixedly connected to the top of each of the two rectangular blocks 321. A top plate 323 is fixedly connected to the top of each slide rod 322. A sliding frame 324 is slidably connected to the outer wall of each slide rod 322. A hot press roller 325 is rotatably connected to the top plate 323. A rotating component is provided on the top plate 323. Both the packaging paper 215 and the film roll 312 are in contact with the hot press roller 325. The discharge component includes several feeding pipes 315 fixedly connected to the bottom of the glue storage tank 314. Each feeding pipe 315 is equipped with a solenoid valve 316. A uniform glue outlet 317 is fixedly connected to the bottom of the feeding pipes 315. The uniform glue outlet 317 is located on the top of the packaging paper 215. The rotating component includes a screw 326 threadedly connected to the top plate 323. A manual turntable 327 is fixedly connected to the top of the screw 326. The bottom end of the screw 326 is rotatably connected to the sliding frame 324. By providing the film covering part 3, in use, one end of the packaging paper 215 can pass through the glue storage tank 314 and extend to the film roll 312. In two steps, the film roll 312 is then placed over the outer surface of the packaging paper 215. After lamination, both are passed through the hot press roller 325 and finally wound onto the take-up roller 214. Since this section of packaging paper is initially uncoated, the film and paper are only initially bonded and not truly adhered. When this section is used later, it can be directly cut off and discarded. Next, multiple solenoid valves 316 on the glue tank 314 will precisely control the glue dispensing according to a preset program. At this time, the motor 222 can also be started simultaneously. The motor 222 will drive the take-up roller 214 to rotate through the rotating shaft 212, winding the packaging paper 215. During this process, the packaging paper 215 will pass through the uniform glue outlet 317 at a uniform speed, so that the glue is evenly applied to its outer surface. As the take-up roller 214 continues to wind, the packaging paper covered with glue is completely wrapped around the paper. Paper 215, along with film roll 312, passes through the preheated hot press roller 325. The hot press fully cures the adhesive, bonding the packaging paper 215 and film roll 312 together. Finally, they are wound together around the outer wall of the take-up roller 214. Simultaneously, if the tension of the hot press roller 325 on the wound material needs adjustment, the manual turntable 327 at the end of the screw 326 can be rotated. The manual turntable 327 will drive the screw 326 to rotate. At this time, the screw 326, guided by two slide rods 322, will drive the slide frame 324 and the rotating hot press roller 325 on the slide frame to move up and down, thereby adjusting the tension of the hot press roller on the take-up roller 214. This setting allows for flexible adaptation to packaging paper and film materials of different thicknesses, ensuring stable material tension during the lamination process and avoiding problems such as wrinkles and misalignment.

[0019] Solenoid valve 316: This is a valve used to control the glue application and feeding action during the packaging paper lamination process. It opens or closes the valve through electromagnetic force, thereby precisely controlling the supply and stop of glue, ensuring the accuracy and stability of glue application and feeding. For example, Graco's iQ series glue application valves include models such as iQ-T pin-sealed type, iQ-S back suction type, and iQ-B ball seat type.

[0020] It should be noted that the control of the hydraulic push rod 216, motor 222, solenoid valve 316 and hot press roller 325 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0021] One specific application of this embodiment is as follows: In use, one end of the packaging paper 215 can be passed through the glue storage tank 314 and extended to the film roll 312. Then, the film roll 312 is placed over the outer surface of the packaging paper 215. After lamination, both are passed through the hot press roller 325 and finally wound onto the take-up roller 214. Since this section of packaging paper is not initially coated with glue, the film and paper are only initially bonded and not truly adhered. When this section is used later, it can be directly cut off and discarded. Then, the multiple solenoid valves 316 on the glue storage tank 314 will precisely control the glue dispensing according to a preset program. At this time, the electric valves can also be activated simultaneously. Machine 222, motor 222 drives take-up roller 214 to rotate via shaft 212, taking up packaging paper 215. During this process, packaging paper 215 passes through glue outlet 317 at a uniform speed, so that glue is evenly applied to its outer surface. As take-up roller 214 continues to take up the paper, the glue-coated packaging paper 215 and film roll 312 pass through preheated hot press roller 325 together. The hot press action fully cures the glue, bonding packaging paper 215 and film roll 312 together, and finally they are wrapped together on the outer wall of take-up roller 214. At the same time, if it is necessary to adjust the hot press roller 325 for the material being taken up, the machine can also adjust the material. The tension of the screw 326 can be adjusted by rotating the manual turntable 327 at the end of the screw 326. The manual turntable 327 will drive the screw 326 to rotate. At this time, the screw 326 will drive the slide frame 324 and the hot pressure roller 325 rotating on the slide frame to move up and down, guided by the two slide rods 322. This adjusts the tension of the hot pressure roller on the take-up roller 214. This setting can flexibly adapt to packaging paper and film materials of different thicknesses, ensuring stable material tension during the lamination process and avoiding problems such as wrinkles and deviations. When the take-up roller 214 is fully wound with the laminated packaging paper 215 and needs to be replaced, the hydraulic push rod 216 can be activated first. Push rod 216 will drive support block 217 to move downward, causing one end of shaft 212 to lose support and be suspended in the air, leaving operating space for disassembly of take-up roller 214. At the same time, the limiting sleeve 213 on the outer wall of shaft 212 will limit take-up roller 214 to prevent it from rotating off the outer wall of shaft 212, ensuring stable position during disassembly. Then, the operator only needs to pull out take-up roller 214 to quickly complete the removal of old roller and installation of new roller. This setting can greatly simplify the take-up roller replacement process, reduce equipment downtime, and improve the overall efficiency of packaging paper lamination operation.
