[0002] In the packaging industry, cartons are common logistics transportation and commodity packaging containers, and their surface protection and aesthetics are extremely important. At present, carton surface lamination is a common method to improve the waterproofness, wear resistance and aesthetics of cartons. Existing carton surface lamination devices mostly use hot pressing lamination technology, which melts the laminating material by heating and then adheres to the surface of the carton. However, in the process of laminating packaging cartons, it is usually necessary to cooperate with a cutting device to cut off the excess film, and the existing cutting device usually lacks a fixing structure for the film, which makes the film easy to loosen during the cutting process and then entangled together, greatly affecting the subsequent lamination effect.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a packaging carton surface coating device. Figure 1, including a processing table 1, a laminating table 3 is installed at the front end of the processing table 1, a limit baffle 10 is connected to the laminating table 3 by screws, the limit baffle 10 can limit the bottom of the packaging carton, a working frame 2 is fixed on the top of the processing table 1, a winding roller 4 is installed on the working frame 2, a film 12 is arranged on the winding roller 4, a rotating shaft 11 supporting the winding roller 4 is installed inside the working frame 2, a servo motor is installed on the outer wall of one side of the working frame 2, the output end of the servo motor passes through the inner wall of the working frame 2 and is connected to the rotating shaft 11, so that the winding roller 4 can be driven to rotate to unwind the film 12.

[0020] like Figure 2 As shown, a guide roller 7 is rotatably installed at the bottom center of the working frame 2, and one end of the film 12 is wound around the bottom of the guide roller 7, and the top of the film 12 can be limited by the guide roller 7, and a cylinder 5 is installed on the top of the end of the working frame 2 away from the winding roller 4, and the output end of the cylinder 5 is connected to the top plate 6, and a pressing plate 16 is fixed at the bottom of the top plate 6. The cylinder 5 can drive the top plate 6 to move downward to position the film 12;

[0021] Balance sliders 8 are symmetrically fixed on both sides of the top plate 6, and the inner wall of the working frame 2 close to one end of the top plate 6 is connected to the slide rail 9 by screws. As the top plate 6 moves, the balance slider 8 will slide and position outside the slide rail 9 to improve the overall stability.

[0022] Combination Figure 3 As shown, a support plate 14 is fixed to one end of the inner wall of the processing table 1 near the top plate 6, a cutting groove 15 is opened on one side of the inner wall of the support plate 14, a through groove slightly longer than the cutting groove 15 is opened on the inner wall of the pressing plate 16, and a cutting frame 13 is fixedly installed on one side of the inner wall of the processing table 1 near the cutting groove 15;

[0023] A motor is installed in the cutting frame 13, and a screw rod 17 is installed inside the cutting frame 13.

The outer wall of the slider 18 is connected to a connecting piece 19 by screws, and a cutting knife 20 is fixed outside the connecting piece 19. The top end of the cutting knife 20 extends to the outside of the cutting groove 15, so that the cutting knife 20 can be driven to move linearly to cut the film 12.

[0024] The implementation principle of a packaging carton surface coating device in the embodiment of the present application is as follows: when in use, the film 12 is unwound by driving the winding roller 4 to rotate, and one end of the film 12 is passed along the bottom of the guide roller 7. At this time, the guide roller 7 can limit the top of the film 12 and play a smoothing role. Then the packaging carton can be placed on the coating table 3, and the film 12 is pulled to cover the outside of the packaging carton for coating. At this time, the cylinder 5 is started, and the cylinder 5 drives the top plate 6 to move downward, and the balancing slider 8 synchronously cooperates with the sliding positioning outside the slide rail 9, and then the pressing plate 16 pushes the film 12 to be positioned close to the upper part of the support plate 14, and then the screw rod 17 in the cutting frame 13 is started to work, and the slider 18 moves on its outer wall through the connecting member 19 to push the cutting knife 20 to one side in the cutting groove 15 and the through groove inside the pressing plate 16, thereby realizing the shearing of the film 12, which is convenient for the subsequent coating work.
