[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] like Figure 1-5 As shown, a laminating and hot pressing device for a color box comprises a frame 1, a conveyor belt, a gluing mechanism, a guide wheel group and a hot pressing mechanism. A channel 101 is provided in the middle of the frame 1, the conveyor belt is mounted in the channel 101, and both ends of the conveyor belt protrude outside the channel 101. Two mounting plates 2 are provided on both sides of the upper end of the frame 1, and the gluing mechanism is mounted between the two mounting plates 2. The guide wheel group comprises a first guide wheel 8, a second guide wheel 9 and a third guide wheel 10. The first guide wheel 8 and the second guide wheel 9 are both rotatably connected between the two mounting plates 2. The first guide wheel 8 is horizontally located on the left side of the gluing mechanism, the second guide wheel 9 is located at the lower left of the first guide wheel 8, and the third guide wheel 10 is rotatably connected to the frame 1 at the right end of the channel 101. A notch 102 is provided at the upper end of the frame 1, and the hot pressing mechanism is mounted on the upper end of the frame 1. The lower end of the hot pressing mechanism can pass through the notch 1 02 and abut against the conveyor belt; the plastic film 16 required for lamination and hot pressing enters the device after unwinding, and is coated with adhesive by the gluing mechanism, and then is received, straightened and transported by the first guide wheel 8, the second guide wheel 9 and the third guide wheel 10 before entering the channel 101, and the color box cardboard 17 that needs lamination and hot pressing enters the conveyor belt of the device through the external conveying mechanism, and the plastic film 16 and the color box cardboard 17 are heated and pressed at the hot pressing mechanism, and the finished product is cut after it is obtained; in the guide wheel group adopted by the present device, the first guide wheel 8 and the second guide wheel 9 can not only play the function of receiving, straightening and transporting, but also contact the surface of the plastic film 16 coated with adhesive, which can smooth the adhesive on the plastic film 16, make the distribution of the adhesive more uniform, further improve the flatness after lamination, and make the lamination effect better.

[0022] In the above embodiment, the gluing mechanism includes a glue box 3 and a glue roller 4. The glue box 3 is fixedly connected between the two mounting plates 2, and the glue roller 4 is rotatably connected between the two mounting plates 2. The lower end of the glue roller 4 is located in the glue box 3, and the upper end of the glue roller 4 is flush with the upper end of the first guide wheel 8; the adhesive is stored in the glue box 3, and the lower end of the glue roller 4 is immersed in the adhesive. Driven by the plastic film 16, the glue roller 4 rotates and brings out the adhesive, so that the adhesive is evenly adhered to the lower surface of the plastic film 16. The side of the mounting plate 2 is provided with a first motor 7, and the output end of the first motor 7 is connected to the glue coating roller 4; the first motor 7 is used to actively control the glue coating roller 4, so as to realize the control of the glue coating amount, and avoid the situation where the glue coating roller 4 and the plastic film 16 slip and cannot be coated normally when there is no power; the first motor 7 can be set in forward and reverse directions. The forward setting is clockwise rotation. At this time, the plastic film 16 and the glue coating roller 4 are in an opposite state, and a large amount of adhesive brought by the glue coating roller 4 adheres to the lower surface of the plastic film 16. When the reverse setting is set, the glue coating roller 4 rotates counterclockwise, and the plastic film 16 and the glue coating roller 4 are in the same direction. The adhesive is squeezed at the junction of the glue coating roller 4 and the plastic film 16, controlling the amount of adhesive passing through the place; the difference between the forward setting and the reverse setting lies in the amount and uniformity of the adhesive coating. The reverse setting will have an additional action of smoothing the adhesive than the forward setting, and the coating amount is about half of that in the reverse setting. The direction can be adjusted according to the laminating process. A glue supply pipe 5 leading to the glue box 3 is provided on the side of the mounting plate 2. This ensures sufficient adhesive in the glue box 3 without interfering with the plastic film 16, and keeps the glue roller 4 immersed in the adhesive. An electronic liquid level sensor 6 is installed in the glue box 3 to monitor the adhesive level. Through the control of an external frequency converter, the glue supply pipe 5 is controlled in real time to maintain the temperature of the adhesive liquid level, thereby ensuring a stable adhesive coating amount and coating effect.

[0023] In the above embodiment, the hot pressing mechanism includes a heating roller 14, a frame 11 and a screw rod 12. The frame 11 is in an inverted U shape. The heating roller 14 is rotatably connected to the frame 11. The lower end of the screw rod 12 is rotatably connected to the frame 11. The frame 11 is slidably connected to the notch 102. A platform 15 is provided at the upper end of the notch 102 of the frame 1. A threaded hole 1501 is provided in the middle of the platform 15. The screw rod 12 is transmission-connected to the threaded hole 1501. The heating roller 14 can abut the conveyor belt; the height of the frame 11 can be adjusted by rotating the screw rod 12, thereby adjusting the distance or abutment pressure between the heating roller 14 and the conveyor belt, and then adjusting the pressing force between the plastic film 16 and the color box paperboard 17, and finally achieving the adjustment of the hot pressing effect; the heating roller 14 is a universal electromagnetic induction steel roller, which can be heated to a specified temperature after being powered on, and can heat and press the plastic film 16 to the surface of the color box paperboard 17 to realize the lamination hot pressing process. The upper end of the screw rod 12 is provided with a regular hexahedron structure 13, which facilitates insertion of a wrench for adjustment. A guide groove 103 is provided on the side of the notch 102, and a guide rail 1101 is provided on the side of the frame 11. The guide rail 1101 is slidably connected to the guide groove 103. The guide groove 103 provides guidance and auxiliary force for the frame 11 with the guide rail 1101, ensuring that the heating roller 14, which is rotatably connected to the frame 11, rises and falls in the vertical direction. This ensures that the heating roller 14 and the conveyor belt are always parallel and stably clamp the plastic film 16 and the color box paperboard 17, allowing for smooth lamination and hot pressing.

[0024] Description of the working method of this utility model:

[0025] Before laminating and hot pressing, the heating roller 14 is powered on and heated to about 100°C. Adhesive is added to the glue box 3 until its liquid level is halfway below the glue roller 4. An external controller is set to monitor the liquid level through the electronic liquid level sensor 6. The adhesive is injected into the glue box 3 from the glue filling pipe 5 through the gear pump to keep the adhesive level in the middle of the glue roller 4. The color box cardboard 17 required for laminating and hot pressing is placed on the conveyor belt after correction by manual or mechanical means, and the plastic film 16 is unwound by the external unwinding mechanism and enters the glue roller 4 of this device horizontally or slightly upwards. At the end, adhesive is applied on the glue roller 4, and then it is received, straightened and transported by the first guide wheel 8 and the second guide wheel 9, while the adhesive is smoothed to make it more uniform. Finally, it turns at the third guide wheel 10 and enters the channel 101; the plastic film 16 and the color box cardboard 17 get closer and closer in the channel 101 until they are bonded together at the hot pressing mechanism. The hot pressing of the heating roller 14 tightly presses the plastic film 16 onto the color box cardboard 17, completing the laminating and hot pressing operation; the color box after lamination is trimmed by the cutting mechanism to obtain the finished product. During the entire process, since the plastic film 16 is continuously coated, the corresponding color box cardboard 17 is also continuously discharged on the conveyor belt, ensuring that the plastic film 16 is continuously hot-pressed onto the color box cardboard 17; after a period of laminating and hot pressing, the conveyor belt needs to be cleaned to remove the overflowed adhesive to ensure that the laminating and hot pressing operation can proceed smoothly.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
