[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners:

[0023] As Figures 1-5 shown, the present utility model provides a packaging box film laminating machine, including a device support 4. In the middle of the inner side of the device support 4, there is a material conveying mechanism 5. The material conveying mechanism 5 is responsible for smoothly and accurately conveying the packaging box to be film laminated from the starting position to subsequent various processing devices. At the top of the material conveying mechanism 5, there is a film laminating and pasting device 1. The film laminating and pasting device 1 accurately laminates the plastic film on the surface of the packaging box, making the film closely combined with the packaging box to complete the preliminary operation of film lamination. Behind the film laminating and pasting device 1, there is a trimming and cleaning device 2. The trimming and cleaning device 2 performs trimming on the film laminated packaging box, removes the excess film edges, and at the same time cleans the waste generated during the trimming process, ensuring that the edges of the packaging box are neat and beautiful, and avoiding environmental pollution caused by the waste. Behind the trimming and cleaning device 2, there is a heating and fixing device 3. The heating and fixing device 3 performs pressurizing and heating on the surface of the trimmed packaging box, further firmly fixing the film on the packaging box and improving the stability and quality of the film lamination.

[0024] Among them, the film laminating and pasting device 1 and the material conveying mechanism 5 are both prior arts and will not be elaborated here.

[0025] As Figure 1As shown in the figure, the present utility model provides a technical solution for a packaging box film laminating machine: Preferably, the heating and fixing device 3 includes a bottom support frame 34. The bottom support frame 34 serves as the basic support structure of the entire heating and fixing device 3. The bottom end of the bottom support frame 34 is fixedly connected to the inside of the device support 4. The top end of the bottom support frame 34 is fixedly connected with a downward pressure support plate 31. The downward pressure support plate 31 has the functions of carrying the downward pressure air cylinder 32 and transmitting pressure. The middle part of the bottom end of the downward pressure support plate 31 is fixedly connected with a downward pressure air cylinder 32, which is a key component for providing driving force in the vertical direction. Four guiding grooves 33 are opened at the top end of the bottom support frame 34. The cooperation between the guiding grooves 33 and the pressure heating component 35 completes the downward film laminating operation. The pressure heating component 35 is arranged in the middle of the inner side of the bottom support frame 34.

[0026] As Figure 1 As shown in the figure, the present utility model provides a technical solution for a packaging box film laminating machine: Preferably, the pressure heating component 35 includes a pressure screw column 353. The top end of the pressure screw column 353 is fixedly connected to the bottom end of the downward pressure air cylinder 32. The bottom end of the pressure screw column 353 is fixedly connected with a downward pressure plate 356. At the four outer corners of the bottom end of the downward pressure plate 356, pressure springs 357 are fixedly connected. The bottom ends of the four pressure springs 357 are jointly fixedly connected with a heating pressure plate 358. A guiding column 354 is arranged inside the pressure spring 357. The bottom end of the guiding column 354 is fixedly connected to the top end of the heating pressure plate 358. The top end of the guiding column 354 penetrates through the downward pressure plate 356 and is slidably connected to the inside of the guiding groove 33. An adjusting plate 355 is sleeved on the outer surfaces of the four guiding columns 354. The middle part of the top end of the adjusting plate 355 is rotatably connected with a pressure adjusting cylinder 351. The inside of the pressure adjusting cylinder 351 is threadedly connected to the outer surface of the pressure screw column 353. The top end of the pressure adjusting cylinder 351 extends to the outside of the top end of the bottom support frame 34. A plurality of adjusting handles 352 are fixedly connected to the upper side of the outer surface of the pressure adjusting cylinder 351.

[0027] When the downward pressure air cylinder 32 is started, its downward thrust is transmitted to the downward pressure plate 356 through the pressure screw column 353 fixedly connected to the top end. After the downward pressure plate 356 is stressed, the pressure is evenly dispersed to the pressure springs 357 fixedly connected to the four corners, thereby driving the heating pressure plate 358 to press downward. When the heating pressure plate 358 contacts the surface of the packaging box, the downward pressure plate 356 continues to press downward, so that the pressure springs 357 are compressed to fix the pressure on the packaging box and the film. By rotating the pressure adjusting cylinder 351, the pressure adjusting cylinder 351 can drive the adjusting plate 355 to move up and down on the guiding column 354. When the adjusting plate 355 moves, the distance between the downward pressure plate 356 and the heating pressure plate 358 changes under the support of the pressure springs 357, so that the contact time between the heating pressure plate 358 and the package is lengthened for adjustment.

[0028] As Figure 1As shown in the figure, the present utility model provides a technical solution for a packaging box film laminating machine: Preferably, the edge trimming and cleaning device 2 includes an edge trimming assembly 21. The edge trimming assembly 21 is the core execution part for edge trimming. Both the left and right sides of the bottom end of the edge trimming assembly 21 are fixedly connected to the inside of the device bracket 4. Support rods 22 are arranged on the front and rear sides of the edge trimming assembly 21. The left and right ends of the support rods 22 are fixedly connected to the inside of the device bracket 4, which plays a role in connecting and supporting the positioning and guiding assembly 23. Two positioning and guiding assemblies 23 are fixedly connected to the support rods 22. One end of the two positioning and guiding assemblies 23 away from the support rods 22 extends into the edge trimming assembly 21, realizing the positioning, guiding of the packaging box and the auxiliary stability function during the edge trimming process.

[0029] As Figure 1 shown in the figure, the present utility model provides a technical solution for a packaging box film laminating machine: Preferably, the positioning and guiding assembly 23 includes a side pressure rod 231. The middle part of the side pressure rod 231 is bent. The upper side of the outer surface of the side pressure rod 231 in the vertical direction is slidably connected to the inside of the support rod 22. One end of the side pressure rod 231 in the inclined direction is rotatably connected to a pressure wheel 235. The lower side of the pressure wheel 235 closely adheres to the top end of the material conveying mechanism 5. A connecting column 234 is fixedly connected to the lower side of the outer surface of the side pressure rod 231 in the vertical direction. A downward pressure spring 233 is arranged on the outer surface of the side pressure rod 231. The bottom end of the downward pressure spring 233 is fixedly connected to the outside of the connecting column 234. The top end of the downward pressure spring 233 is fixedly connected to a support column 232. The support column 232 is sleeved on the outer surface of the side pressure rod 231. The top end of the support column 232 is fixedly connected to the bottom end of the support rod 22.

[0030] When the packaging box moves to the lower part of this positioning and guiding assembly 23 along with the material conveying mechanism 5, the thickness of the packaging box will cause a corresponding displacement of the side pressure rod 231 in the vertical direction. If the packaging box is thicker, it will push up the connecting column 234 upward. The connecting column 234 drives the side pressure rod 231 to slide upward inside the support rod 22. At this time, the downward pressure spring 233 is further compressed, and its elastic potential energy increases, which can provide a greater downward pressure to meet the positioning requirements of a thicker packaging box. If the packaging box is thinner, under the action of the elastic restoring force of the downward pressure spring 233, the connecting column 234 drives the side pressure rod 231 to move downward a certain distance, so that the pressure wheel 235 can still closely adhere to the surface of the packaging box, ensuring the effective positioning of packaging boxes with different thicknesses.

[0031] As Figure 1As shown in the figure, the utility model provides a technical solution for a packaging box film laminating machine: Preferably, the edge cutting assembly 21 includes a support block 211. Inside the support block 211, a motor mounting plate 217 is fixedly connected. At the lower side of the rear end of the motor mounting plate 217, two left - and - right parallel moving wheels 212 are rotatably connected. The outer surfaces of the two support blocks 211 are jointly rotatably connected with a conveyor belt. At the lower - side outer surface of the conveyor belt, a laser cutting head 213 is fixedly connected. At the outer surface of the laser cutting head 213, a dust suction head 214 is fixedly connected. At the middle of the rear end of the motor mounting plate 217, a dust suction connecting head 216 is rotatably connected. Between the dust suction connecting head 216 and the dust suction head 214, a dust suction pipe 215 is fixedly connected. At the front end of one of the moving wheels 212, a forward - reverse motor is provided.

[0032] Taking the forward - reverse motor as the power source, after starting, it drives one of the moving wheels 212 connected to it to rotate. The rotating moving wheel 212 drives the conveyor belt to move through friction, so that the other moving wheel 212 also rotates synchronously, realizing the circular operation of the conveyor belt. The laser cutting head 213 moves in a circular motion along with the conveyor belt. When the packaging box is conveyed to the edge - cutting position under the action of the positioning and guiding assembly 23, the laser cutting head 213 just moves above the edge of the packaging box to cut the redundant film on the edge of the packaging box. During the cutting process, the waste generated is sucked by the suction force generated by the dust suction head 214, conveyed to the dust suction connecting head 216 through the dust suction pipe 215, and then collected into a designated waste collection device.

[0033] Among them, laser cutting technology uses a laser beam with a high energy density to focus on the surface of the material, causing the material to quickly melt, vaporize or reach the ignition point, thereby realizing cutting. The dust suction connecting head 216 is connected to a dust suction device that generates negative pressure, and both are existing technologies and will not be explained here.

[0034] Next, the working principle of this packaging box film laminating machine will be specifically described.

[0035] As Figures 1-5As shown in the figure, place the packaging box to be laminated at the starting position of the material transfer mechanism 5, ensure that the laminating material is installed in the laminating and pasting device 1, turn on the device power supply, the material transfer mechanism 5 conveys the packaging box to the lower part of the laminating and pasting device 1, and the laminating and pasting device 1 pastes the plastic film on the surface of the packaging box to complete the preliminary operation of lamination. The laminated packaging box is then continuously conveyed by the material transfer mechanism 5 to the edge trimming and cleaning device 2. The positioning and guiding component 23 first flattens and positions the packaging box, adapts to the thickness of the packaging box and automatically clamps it tightly. Then, the edge trimming component 21 is activated. The forward and reverse motor drives the moving wheel 212 to make the conveyor belt run, and the laser cutting head 213 cuts the excess film at the edge of the packaging box. The dust suction head 214 synchronously sucks away the waste materials. The edge-trimmed packaging box enters the heating and fixing device 3 area. The downward pressing air rod 32 pushes the pressure screw column 353, and drives the heating pressure plate 358 to press down through the downward pressing pressure plate 356 and the pressure spring 357 to heat and press the packaging box, so that the lamination is firmly fixed. The pressure can be adjusted by rotating the pressure adjusting cylinder 351 as needed. Finally, it is output from the end of the material transfer mechanism 5 and can be used for subsequent packaging or storage.

[0036] The above text generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
