[0029] As shown in Figure 4 and Figure 5As shown, it also includes a crossbar 17, threaded rods 1701 and scrapers 1702, the top of the glue storage tank 8 is fixedly connected with the crossbar 17, the crossbar 17 is symmetrically and rotatably connected with the threaded rods 1701, the two threaded rods 1701 are rotatably connected with the scrapers 1702 through the connecting seats, so that the scrapers 1702 can stably ascend and descend when the threaded rods 1701 rotate, and the protrusions on the two sides of the scrapers 1702 are respectively clamped into the grooves on the two sides of the glue storage tank 8.

[0030] As shown in Figure 1 and Figure 8 As shown, it also includes a discharging table 19 and a fan 20, the front side of the glue storage tank 8 is connected with the discharging table 19, and a plurality of transverse grooves are uniformly formed in the discharging table 19 to prevent the completed packaging box paperboard from being adhered to the workbench, and the fan 20 is symmetrically installed on the left and right sides of the discharging table 19 and is electrically connected with the controller 7.

[0031] When using the device, first of all, the device needs to be placed on a flat ground to ensure that it will not tilt or move due to uneven ground. When starting the glue operation on the packaging box paperboard, the user can first start the heating assembly 18 through the controller 7, and the heating pipe will heat the glue inside the glue storage tank 8 to prevent the glue from drying and hardening during the operation of the device, thereby affecting the gluing effect. Then start the drive motor 9 through the controller 7, the output shaft of the drive motor 9 drives the glue roller 10 to rotate in the clockwise direction, so that the surface of the glue roller 10 is covered with glue, at the same time, the glue roller 10 also drives the first gear 13 to rotate in the clockwise direction when rotating, thereby driving the second gear 14 meshing with the first gear 13 to rotate counterclockwise, thereby driving the first roller 11 to rotate. The two third gears 15 meshing with the second gear 14 also rotate clockwise, thereby driving the two second rollers 12 to rotate clockwise. Because the glue adhering to the outer lateral wall of the glue roller 10 has a certain thickness, and the thickness of the glue fills the gap between the glue roller 10 and the first roller 11, so that the glue adhering to the outer lateral wall of the glue roller 10 can be uniformly transferred to the outer lateral wall of the first roller 11, and then adhered to the outer wall of the two second rollers 12, thereby achieving the effect of uniformly adhering the glue to the first roller 11 and the second roller 12, which helps to improve the bonding quality of the packaging box paperboard and also improves the overall production efficiency. When the third gear 15 at the rear side rotates clockwise, the rotating rod 602 connected with the third gear 15 through the belt 16 also rotates in the clockwise direction, which enables the paper rubbing wheel 601 to continuously rotate clockwise.

[0032] When the packaging box paperboard needs to be glued, the packaging box paperboard to be glued is placed on the feeding table 2. In this process, the packaging box paperboard will be pressed against the baffle 4 on both sides, causing the second spring 5 to be compressed, and through the reaction force of the second spring 5, the baffle 4 will preliminarily clamp the packaging box paperboard, thereby preventing the paperboard from moving randomly. This clamping method can adapt to packaging box paperboards of different widths, thereby realizing the basic clamping function. Push the stop piece 101 forward, and the stop piece 101 drives the packaging box paperboard to move forward together until it reaches the page separating block 301. Due to the blocking effect of the stop piece 101, when the paperboard reaches the pressing plate 3, even if the pressing plate 3 is inclined, the paperboard will not fall off. As the number of packaging box paperboards on the feeding table 2 changes, the first spring 303 will be correspondingly pressed downward, but will always maintain a height that meets the requirements. Under the condition that the third gear 15 drives the rotating rod 602 to rotate, the paper rubbing wheel 601 starts to rotate. When the paper rubbing wheel 601 rotates to the side with a longer diameter and contacts the packaging box paperboard, the paper rubbing wheel 601 will rely on friction to push the packaging box paperboard forward. However, due to the friction between the paperboards, the second paperboard may also move. At this time, the other paperboards rubbed up will be blocked by the page separating block 301, and only the uppermost paper will continue to be conveyed forward. In this process, the auxiliary wheel 302 can make the movement of the paper more smooth. This way can effectively avoid the situation that multiple paperboards are conveyed at the same time while ensuring the normal conveying of the paper, is simple and convenient to operate, saves manpower, and improves the efficiency of the paper conveying link in the entire gluing process. Then, the paper rubbing wheel 601 pushes the packaging box paperboard forward between the second roller 12 and the first roller 11. Because the two rollers are in a rotating state at the same time, the packaging box paperboard will continue to move forward after being stained with glue, until it reaches the discharging table 19. At this time, the controller 7 opens the air blowers 20 on both sides of the discharging table 19, and the air blowers 20 will dry the packaging box paperboard after gluing. After the drying program is completed, the operator can take away the packaging box paperboard after gluing.

[0033] During the gluing process of the packaging box paperboard, sometimes the amount of glue needs to be adjusted. At this time, the threaded rod 1701 on both sides of the horizontal rod 17 can be rotated upward to drive the scraper 1702 to rotate upward together. If more glue is needed, the scraper 1702 is rotated upward; if less glue is needed, the scraper 1702 is rotated downward. In this way, the distance between the scraper 1702 and the glue applying component can be changed, thereby effectively controlling the amount of glue and achieving the effect of adjustable glue amount.

[0034] After the packaging box paperboard conveying is completed, the first spring 303 is no longer pressed to drive the pressing plate 3 to reset, and the four second springs 5 are no longer pressed to drive the baffle 4 to reset. After the device is used, the controller 7 can be used to sequentially turn off the heating assembly 18, the driving motor 9, and the air blower 20.

[0035] The above has introduced the present application in detail, the principle and implementation mode of the present application are described in this paper by applying specific examples, the above example is only used to help understand the method of the present application and its core idea; At the same time, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed, and the above is not understood as the limitation of the present application.
