Clamping mechanisms are arranged inside both of the two sliding grooves. A support frame 5 is arranged on one side of the sliding groove. A moving groove is formed at the top of the support frame 5. A moving block 6 is arranged inside the moving groove. A glue coating mechanism is arranged at the bottom of the moving block 6. Two leveling mechanisms are arranged inside the sliding groove. Both of the two leveling mechanisms include a first electric telescopic rod 7 arranged inside the sliding groove. A first slider 8 is arranged at the bottom of one of the first electric telescopic rods 7. The first slider 8 is slidably connected to the sliding groove. Scraping plates 9 are arranged at the tops of both of the first electric telescopic rods 7. A cavity is formed inside one of the scraping plates 9. A first sponge is arranged inside the cavity. The top of the scraping plate 9 is connected with a cover plate 10 through a hinge. The device is moved to the required position through the universal wheels 4 at the bottom of the working plate 1. The cardboard to be coated with glue is placed on the conveyor belt 2. The first electric telescopic rod 7 adjusts the height of the scraping plate 9, making it convenient to level the cardboard. When the cardboard is placed on the conveyor belt 2, the scraping plate 9 scrapes the surface of the cardboard, facilitating uniform glue coating on the surface of the cardboard and preventing wrinkles on the surface of the cardboard, which may lead to uneven glue coating. Then, another scraping plate 9 scrapes the glued cardboard, which can not only trim the thickness of the glue but also facilitate scraping off the excess glue. The excess glue is absorbed by the first sponge inside the scraping plate 9. And by opening the cover plate 10 at the top of the scraping plate 9, it is convenient to take out the first sponge for cleaning and replacement.

[0020] Referring to Figure 1 and Figure 3 As shown, the clamping mechanism includes two second electric telescopic rods 11 arranged inside the sliding groove. Second sliders 12 are arranged at one ends of both of the second electric telescopic rods 11. The second sliders 12 are slidably connected to the sliding groove. A third electric telescopic rod 13 is arranged at the top of the second slider 12. A clamping plate 14 is arranged at one end of the third electric telescopic rod 13. A second sponge 15 is clamped inside the clamping plate 14. The third electric telescopic rod 13 drives the clamping plate 14 to rise, facilitating clamping of the cardboard. The second electric telescopic rod 11 drives the second slider 12 to slide inside the sliding groove, enabling the clamping plate 14 to slide along with the cardboard on the conveyor belt 2, preventing deviation during glue coating of the cardboard. When the cardboard is limited by the clamping plate 14, the excess glue during glue coating of the cardboard is absorbed by the second sponge 15 clamped inside the clamping plate 14, preventing waste of excess glue.

[0021] Referring to Figure 2 and Figure 4As shown, the gluing mechanism includes a cylinder 16 arranged at the bottom of the moving block 6. One end of the cylinder 16 extends to the outside of the support frame 5. A gluing base 17 is arranged at one end of the cylinder 16. Two paint buckets 18 are arranged on the top of the gluing base 17. Two material guiding holes 19 are formed inside the gluing base 17. The material guiding holes 19 are connected to the paint buckets 18. Card slots are formed on both sides inside the gluing base 17. A gluing plate 20 is snap-connected to the bottom of the gluing base 17. Fixed holes are formed on both sides of the gluing plate 20. Springs 21 are arranged inside the two fixed holes. A positioning block 22 is arranged at one end of the spring 21. The positioning block 22 is snap-connected to the card slot. A material feeding hole 23 is formed inside the gluing plate 20. The material feeding hole 23 is communicated with the material guiding hole 19. A sponge plate is arranged at the bottom of the material feeding hole 23. A gluing brush 24 is arranged at the bottom of the sponge plate. It is conveyed below the gluing base 17. At the same time, the cylinder 16 is used to drive the gluing base 17 to descend, so that the gluing brush 24 of the gluing plate 20 glues the corrugated cardboard. At the same time, the sponge plate effectively prevents excessive paint. After gluing is completed, the corrugated cardboard is moved out of the gluing position. The arrangement of the card slot and the positioning block 22 makes the gluing plate 20 easy to disassemble, facilitating the subsequent cleaning of the gluing brush 24.

[0022] Working principle of the utility model: First, move the device to the required position through the universal wheels 4 at the bottom of the working plate 1, place the cardboard to be glued on the conveyor belt 2, and adjust the height of the squeegee 9 by the electric telescopic rod 1. This makes it convenient to level the cardboard. When the cardboard is placed on the conveyor belt 2, the squeegee 9 scrapes the surface of the cardboard, facilitating uniform gluing on the cardboard surface and preventing uneven gluing caused by wrinkles on the cardboard surface. Then, another squeegee 9 scrapes the glued cardboard, which can not only trim the thickness of the glue but also facilitate scraping off the excess glue. The excess glue is absorbed by the first sponge inside the squeegee 9, and by opening the cover plate 10 on the top of the squeegee 9, it is convenient to take out the first sponge for cleaning and replacement. The electric telescopic rod 3 drives the clamping plate 14 to rise, facilitating the clamping of the cardboard. The electric telescopic rod 2 drives the second slider 12 to slide in the chute, enabling the clamping plate 14 to slide with the cardboard on the conveyor belt 2, preventing deviation during gluing of the cardboard. When limiting the cardboard by the clamping plate 14, the excess glue on the cardboard during gluing is absorbed by the second sponge 15 clamped inside the clamping plate 14, preventing waste of excess glue. It is then conveyed until it is below the gluing base 17. Meanwhile, the cylinder 16 is used to drive the gluing base 17 to descend, so that the gluing brush 24 of the gluing plate 20 glues the corrugated cardboard. At the same time, the sponge plate effectively prevents excessive coating. After gluing is completed, the corrugated cardboard moves out of the gluing position. In addition, the clamping plate 14 can limit corrugated cardboard of different widths, facilitating gluing of corrugated cardboard of different widths, thereby improving the multi-applicability of the device. The setting of the card slot and the positioning block 22 makes it convenient to disassemble the gluing plate 20, facilitating subsequent cleaning of the gluing brush 24.

[0023] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
