[0032] 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.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a plastic packaging box laminating device, including a supporting base plate 1. The supporting base plate 1 serves as the fundamental load-bearing component of the entire device, possessing good rigidity and stability, capable of withstanding various forces generated during device operation, ensuring the overall structural stability of the device. A supporting base 2 is fixedly connected to the top of the supporting base plate 1, ensuring that it does not deform or shake when supporting the components above. A supporting base 9 is fixedly connected to the inner top side of the supporting base 2, and a supporting base 10 is fixedly connected to the top of the supporting base 2. The supporting base 9 and the supporting base 10 together constitute the main frame of the heating and cooling mechanism. The interiors of the supporting base 9 and the supporting base 10... A heating and cooling mechanism is fixedly connected. The heating and cooling mechanism includes two support bases 10. The two support bases 10 are fixedly connected to the inside of the support base 9. A cooling fan 11 is fixedly connected to the side of the support base 10 away from the support base 10. When the cooling fan 11 is activated, it accelerates the air flow through forced convection to quickly dissipate the heat around the heating and bonding column 12, preventing the temperature from being too high and affecting the normal operation and service life of the equipment. The heating and bonding column 12 is rotatably connected inside the cooling fan 11. When the cooling fan 11 is activated, it accelerates the air flow through forced convection to quickly dissipate the heat around the heating and bonding column 12, preventing the temperature from being too high and affecting the normal operation and service life of the equipment.

[0034] A cooling plate 13 is fixedly connected to the top inner side of the support base 2 10. When the heated and bonded plastic box 3 passes under the cooling plate 13, the cooling plate 13 quickly absorbs the heat from the surfaces of the plastic box 3 and the roll film 7, causing the hot melt adhesive to solidify rapidly and enhancing the bonding strength between the film and the plastic box 3. Multiple heat dissipation holes 15 are evenly distributed on the top inner side of the support base 2 10, which can promptly dissipate the heat generated inside the heating and cooling mechanism to the external environment, further improving heat dissipation efficiency. Support connecting plates 14 are fixedly connected to the inside of both sides of the support base 2 10. A rolling assembly is fixedly connected inside the support base 2 10. The rolling assembly includes an electric telescopic column 16. By controlling the extension length of the electric telescopic column 16, the distance and pressure between the rolling column 19 and the plastic box 3 are adjusted. The electric telescopic column 16 is externally fixedly connected to the support base. Inside the top side of the second support base 10, the drive end of the electric telescopic column 16 is fixedly connected to the support connecting seat 18. Two follower telescopic columns 17 are fixedly connected to the top of the inner side of the second support base 10. The bottom of the follower telescopic columns 17 is fixedly connected to the top of the support connecting seat 18. The follower telescopic columns 17 play an auxiliary support and guiding role when the electric telescopic column 16 is working, ensuring that the support connecting seat 18 and the rolling column 19 remain stable during the up and down movement. The rolling column 19 is rotatably connected inside the support connecting seat 18. When working, the rolling column 19 moves downward under the drive of the electric telescopic column 16 to roll the film on the surface of the plastic box 3. By rotating itself, it compacts the film, making the film adhere more firmly to the plastic box 3, and further eliminating any air bubbles and unevenness. A collection mechanism is fixedly connected to the top of the support base plate 1.

[0035] Reference Figure 1 , Figure 4 and Figure 5The collection mechanism includes a collection box 22 for collecting finished plastic packaging boxes that have undergone lamination and cutting. A double-layer rubber pad 23 is fixedly connected inside the collection box 22. The double-layer rubber pad 23 has good cushioning performance and can effectively protect the collected plastic packaging boxes from damage during transportation and storage. Two sensor detectors 24 are fixedly connected to both sides inside the collection box 22. The sensor detectors 24 use infrared and photoelectric sensing technology to detect the quantity of finished products in the collection box 22 in real time, as well as to detect uneven lamination. An inclined plate 2 is slidably connected to the collection box 22. 5. Two support plates 4 are fixedly connected to the top of the support base 2. A cutting assembly is fixedly connected inside the support plate 4. The cutting assembly includes two drive slide rails 20. The drive slide rails 20 provide sliding support and guidance for the slice 21, enabling it to make precise linear movement inside the support plate 4. The two drive slide rails 20 are fixedly connected to the inside of the support plate 4. The slice 21 is fixedly connected to the side of the two drive slide rails 20 away from the support plate 4. The slice 21 cuts off the excess part of the roll film 7 covering the plastic box 3, so that the plastic packaging box after film covering has neat edges.

[0036] The cutting angle and depth of the slice 21 are adjusted according to actual needs to adapt to the cutting requirements of roll film 7 of different thicknesses and materials. A conveyor belt 26 is fixedly connected inside the support base 2. An inclined plate 25 is fixedly connected to the bottom right side of the support base plate 1. The design of the inclined plate 25 allows the plastic packaging box that has been laminated and cut to slide smoothly into the collection box 22 under its own weight. A plastic box 3 is slidably connected to the top of the conveyor belt 26. The bottom of the two heating and bonding columns 12 is slidably connected to the top of the plastic box 3, which transports the plastic box 3 to each working position at a predetermined speed and direction, ensuring the continuity and stability of the entire lamination process. The bottom of the rolling column 19 is slidably connected to... At the top of the plastic box 3, a rotating column 5 is rotatably connected inside the support plate 4, and a U-shaped support seat 6 is fixedly connected to the top of the support plate 4. A rotating roller 8 is slidably connected inside the U-shaped support seat 6, and a roll film 7 is rotatably connected to the outside of the rotating roller 8. The bottom of the roll film 7 is slidably connected to the top of the plastic box 3. The rotating column 5, the U-shaped support seat 6, and the rotating roller 8 together constitute the unwinding support structure of the roll film 7. Under its own weight and the traction of the conveyor belt 26, the roll film 7 gradually unfolds by the rotation of the rotating roller 8 and covers the top of the plastic box 3. The bottom of the slice 21 is slidably connected to the top of the roll film 7, which can ensure that the roll film 7 unfolds and is conveyed smoothly, and at the same time facilitates the operator to replace the roll film 7.

[0037] Working principle: First, the coated plastic box 3 is placed inside the support base 1 9. The support base 2 10 drives the cooling fan 11 to move up and down, thereby driving the heating and bonding column 12 to heat the surface of the plastic box 3, so that the coating is quickly bonded. After bonding, it enters the support base 2 10, where the support connecting plates 14 on both sides are activated and the cooling plate 13 on the top absorbs heat. At the same time, while the support connecting plates 14 are activating to dissipate heat, the heat dissipation holes 15 can dissipate internal heat. After cooling, the electric telescopic column 16 is activated, and the follow-up telescopic column 17 moves accordingly, driving the rolling column 19 to rotate inside the support connecting seat 18, rolling the surface of the plastic box 3 again, reducing the presence of air bubbles and unevenness during cooling, improving the quality of coating bonding, increasing production efficiency, and ensuring that the surface of the plastic box 3 reaches the best flatness and aesthetics after cooling.

[0038] Secondly, the plastic box 3 is placed on the conveyor belt 26, which transports it to various working positions at a predetermined speed and direction. At the same time, the roll film 7 is gradually unrolled by the rotation of the rotating roller 8, covering the top of the plastic box 3. The unwinding support structure of the roll film 7 is composed of the rotating column 5, the U-shaped support seat 6, and the rotating roller 8, ensuring that the roll film 7 can be laid stably on the surface of the plastic box 3. The film is cut by the slice 21 driven by two drive slide rails 20. After cooling, the plastic box 3 enters the collection box 22 for inspection through the inclined plate 25. The double-layer rubber pad 23 protects the plastic box 3 at the bottom. After entering the collection box 22, it is inspected by two support plates 4, and unqualified plastic boxes 3 are detected, which improves the product qualification rate and enhances the product quality stability and consistency.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
