[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a glue application device for printing and packaging as shown in Figure 1 - Figure 5 which includes a glue application table 1 and a cardboard 4. A glue application roller 2 and a pressing roller 3 are arranged at the upper end of the glue application table 1. The cardboard 4 passes through the glue application roller 2 and the pressing roller 3. The glue application roller 2 applies glue to the cardboard 4, and then the pressing roller 3 presses multiple layers of cardboard 4 to improve the adhesion. Among them, both the glue application roller 2 and the pressing roller 3 are driven by servo motors, which is prior art and will not be described in detail here.

[0026] Two rectangular grooves 5 are opened at the upper end of the glue application table 1 for recovering excess glue. The glue of the cardboard 4 is generally composed of water and starch, which is prior art and will not be described in detail here.

[0027] A mesh plate 6 for supporting the cardboard 4 is fixedly arranged on the inner wall of the rectangular groove 5. An open slot 7 is penetrated on one side of the mesh plate 6. A sliding plate 8 is slidably arranged inside the open slot 7. The sliding plate 8 is arranged in an I shape. A side scraping plate 9 for cleaning the side of the cardboard 4 is movably arranged at one end of the sliding plate 8. An upper scraping plate 10 for cleaning the upper end of the cardboard 4 is fixedly arranged at the upper end of the side scraping plate 9. Through the arrangement of the side scraping plate 9 and the upper scraping plate 10, the excess glue between the cardboards 4 is scraped off as the cardboard 4 is conveyed during glue application, preventing too much glue from affecting the quality of the cardboard 4. It can also seal the side of the cardboard 4 with glue to improve the firmness at the edge of the cardboard 4 and improve the quality of the cardboard 4;

[0028] The upper squeegee 10 is inclined. There is a diversion groove 11 on one side of the side squeegee 9. A plurality of storage grooves 12 are provided at the corners of the side squeegee 9 corresponding to the cardboard 4. The storage grooves 12 are triangular in shape, facilitating the storage of glue. Through the setting of the diversion groove 11, it is convenient for the scraped glue to be discharged. And through the setting of the storage grooves 12, the glue can be stored in the storage grooves 12. Thus, when there is no glue running out of the outside of the cardboard 4, the stored glue can be used to seal the edge of the cardboard 4.

[0029] A guide rod 14 is fixedly provided at the upper end of the gluing table 1. The end of the guide rod 14 is fixedly connected to the inner wall of the opening groove 7. A compression spring 15 is sleeved outside the guide rod 14. The end of the compression spring 15 is fixedly connected to the gluing table 1 and one end of the sliding plate 8. A circular hole for the guide rod 14 to pass through is formed through one side of the sliding plate 8.

[0030] One end of the sliding plate 8 is fixedly provided with a telescopic plate 13. The end of the telescopic plate 13 is fixedly connected to the side squeegee 9 through a spring, so that the upper squeegee 10 is always in contact with the upper end of the cardboard 4 through the spring.

[0031] Through the setting of the compression spring 15 and the telescopic plate 13, the side squeegee 9 and the upper squeegee 10 can move, facilitating the adaptation to cardboard 4 of various widths and thicknesses.

[0032] A plurality of mesh holes are formed through one side of the mesh plate 6, facilitating the glue to pass through and enter the rectangular groove 5.

[0033] Working principle: The operator turns on the servo motor, so that the pressing roller 3 and the gluing roller 2 press and glue the cardboard 4. Then the cardboard 4 is placed below the upper squeegee 10, making the upper squeegee 10 closely adhere to the cardboard 4. When the pressing roller 3 presses the cardboard 4, the side squeegee 9 and the upper squeegee 10 scrape off the excess glue on the cardboard 4, so that the excess glue is scraped off and enters the interior of the rectangular groove 5 through the mesh holes on the mesh plate 6;

[0034] When the size of the cardboard 4 changes, the sliding plate 8 is moved, so that the sliding plate 8 drives the telescopic plate 13 to move. The telescopic plate 13 drives the side squeegee 9 to move. The side squeegee 9 then drives the upper squeegee 10 to move, so that the side squeegee 9 fits against the side of the cardboard 4. Through the setting of the spring, the side squeegee 9 can move up and down, so that the side squeegee 9 drives the upper squeegee 10 to move up and down. According to the thickness of the cardboard 4, the height of the upper squeegee 10 is adjusted for the thickness of the cardboard 4. Then, through the pulling force of the spring, the spring drives the side squeegee 9 to move. The side squeegee 9 drives the upper squeegee 10 to move, so that the upper squeegee 10 closely adheres to the cardboard 4;

[0035] Through the arrangement of the extrusion spring 15, the extrusion spring 15 is further enabled to extrude the sliding plate 8, so that the sliding plate 8 moves towards the cardboard 4. Until the sliding plate 8 drives the side scraping plate 9 to move, making one end of the side scraping plate 9 closely adhere to the cardboard 4.
