[0035] Example 2

[0036] As Figures 1-5As shown, the present invention proposes a packaging box outer surface printing and laminating device. Compared with embodiment 1, as another implementation of the present invention, the laminating assembly includes a guide roller (15), a laminating roller (16), a film to be printed (17), a roller frame (18), a heating roller (19), and a lifting cylinder (20). The guide roller (15) is provided on the side of the ion roller (14) away from the adsorption tank (10). The laminating roller (16) is installed directly above the guide roller (15). The film to be printed (17) is provided on the laminating roller (16). The roller frame (18) is provided at the end of the laminating roller (16) away from the ion roller (14). A heating roller (19) is rotatably connected to the bottom of the roller frame (18), and a lifting cylinder (20) is set directly above the roller frame (18). The lifting cylinder (20) is welded to the top of the machine body (1), and the output end of the lifting cylinder (20) is fixed on the roller frame (18). During operation, by setting the heating roller (19), the heating roller (19) is in close contact with the surface of the packaging box (5) to be coated, which can heat the film (17) to be printed and the packaging box (5) to be coated, accelerate the bonding rate, and also pressurize the film (17) to be printed and the packaging box (5) to be coated, thereby increasing the bonding area of ​​the film (17) to be printed and the packaging box (5) to be coated.

[0037] Furthermore, the film to be printed (17) is guided by the guide roller (15) and then closely adhered to the packaging box (5) to be coated. During operation, by setting the guide roller (15), it is beneficial to guide the film to be printed (17) to the packaging box (5) when it is rolled out from the coating roller (16). After the guide roller (15) guides the film to be printed (17), the film to be printed (17) can be completely and tightly adhered to the packaging box (5) to be coated, thereby realizing the control operation of the complete adhesion between the packaging box (5) to be coated and the film to be printed (17).

[0038] During operation, the packaging box (5) to be coated is first placed on the feeding roller (3), and the starting end of the packaging box (5) to be coated is placed on the receiving roller (4). Then the receiving roller (4) starts to wind up the packaging box (5) to be coated. The conveyor roller (6) drives the conveyor belt (7) to rotate, so that the packaging box (5) to be coated moves along the conveyor belt (7). The packaging box (5) to be coated is first limited by the limiting flattening roller (8). The limiting flattening roller (8) limits the packaging box (5) to the middle position of the conveyor belt (7). Then the preheating roller (9) preheats the packaging box (5) to be coated. Heating the packaging box (5) to be coated facilitates the adhesion of the subsequent printed film (17).

[0039] Next, the adsorption hydraulic press (13) starts working. The adsorption hydraulic press (13) drives the adsorption fixing plate (11) to move downward. The adsorption fixing plate (11) then drives the adsorption groove (10) on the lower surface wall to move downward to the upper surface of the packaging box (5) to be coated. At this time, the adsorption motor (22) starts working and draws the air inside the adsorption groove (10) into the collection box (23) through the adsorption telescopic tube (12) and the adsorption fixing tube (21). The dust particles and other particles drawn out are collected in the collection box (23). The dust particles and other particles on the surface of the packaging box (5) to be coated are sucked out to avoid uneven coating surface caused by dust particles and other particles during subsequent coating. After adsorption is completed, the packaging box (5) to be coated is moved to the bottom of the ion roller (14). The ion roller (14) removes static electricity from the surface of the packaging box (5) to be coated to prevent wrinkles caused by static electricity on the surface of the packaging box (5) to be coated, effectively avoiding uneven coating caused by wrinkles.

[0040] Finally, the laminating roller (16) drives the film to be printed (17) to rotate downwards. After being turned by the guide roller (15), the film to be printed (17) adheres to the surface of the packaging box (5) to be laminated. The film to be printed (17) and the packaging box (5) to be laminated move backwards together with the conveyor belt (7) to directly below the heating roller (19). The lifting cylinder (20) then starts working, driving the roller frame (18) to move downwards. The roller frame (18) then drives the heating roller (19) to move downwards to the surface of the packaging box (5) to be laminated. The heating roller (19) is in close contact with the surface of the packaging box (5) to be laminated, thus laminating the film to be printed (17) and the packaging box (5) to be laminated. The box (5) is heated to accelerate the bonding rate and to pressurize the film to be printed (17) and the packaging box to be laminated (5), thereby increasing the bonding area between the film to be printed (17) and the packaging box to be laminated (5). Then the electric push rod (26) starts to work and drives the scraper (25) to move downward to the surface of the packaging box to be laminated (5) through the scraper frame (24). The scraper (25) scrapes and presses the surface of the packaging box to be laminated (5), so that the film to be printed (17) and the packaging box to be laminated (5) are completely bonded, which greatly improves the efficiency of printing and laminating. The packaging box to be laminated (5) after printing and laminating is collected inside the receiving roller (4).

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
