[0039] Specifically, the staff opens the box cover and pours the colloid into the inner side of the glue box 5 in advance, and then closes the box cover. The colloid will flow through the opening of the glue box 5 to the inner side of the glue brush 6, so that the colloid on the glue brush 6 can flow to the first roller 3. The controller controls the drive motor 2 to operate, so that the output end of the drive motor 2 rotates to drive the first roller 3 to roll, so that the surface of the first roller 3 is contaminated with the colloid due to contact with the glue brush 6.

[0040] In this embodiment, the limiting mechanism includes two round shells 9 symmetrically fixedly installed on both sides of the feeding shell 8, a spring 10 is connected to the inner wall of each round shell 9, the end of the spring 10 is connected to a limiting plate 11, and a movable rod 12 is fixedly installed on the limiting plate 11. The adjustment mechanism includes two support frames 13 symmetrically fixedly installed on both sides of the feeding shell 8, a long plate 14 is fixedly installed between the two support frames 13, and four slide grooves 15 are symmetrically opened at the top and bottom ends of the long plate 14. The adjustment mechanism also includes two serrated plates 16 fixedly installed on the long plate 14, and the adjustment mechanism also includes a slider 18 movably installed on the inner side of the slide groove 15, and every two sliders 18 A movable frame 19 is fixedly installed on the above-mentioned movable rods 12, a connecting frame 17 is fixedly installed on the end of each movable rod 12, and each end of the connecting frame 17 is fixedly connected to the movable frame 19 at the corresponding position. The adjusting mechanism also includes an inner rod 20 fixedly installed on the inner side of the movable frame 19, and a block 21 adapted to the serrated plate 16 is movably installed on the inner rod 20, and two torsion springs 22 are connected to the block 21, and the block 21 is connected to the movable frame 19 through two torsion springs 22.

[0041] Specifically, the staff moves the connecting frame 17 so that the connecting frame 17 drives the slider 18 to move along the inner side of the slide groove 15 through the moving frame 19 under the action of external force. At the same time, the connecting frame 17 can drive the limit plate 11 to move under the support of the elastic force of the spring 10. The moving frame 19 drives the block 21 to move along the serrated plate 16 through the inner rod 20 under the support of the elastic force of the torsion spring 22. The block 21 rotates around the inner rod 20 as the center under the abutment of the serrated plate 16 and the support of the elastic force of the torsion spring 22. The position of the limit plate 11 is adjusted according to the corrugated cardboard coated with glue and the ruler 25, so that the block 21 is clamped at the appropriate position of the serrated plate 16, and the block 21 is fixed by the abutment bolt 24, so that the limit plate 11 is fixed, so that the size of the corrugated cardboard feeding position can be adjusted easily, thereby improving practicality.

[0046] Working principle: the staff opens the box cover, pours the colloid into the inner side of the glue box 5 in advance, and then closes the box cover. The colloid will flow to the inner side of the glue brush 6 through the opening of the glue box 5, so that the colloid on the glue brush 6 can flow to the first roller 3. The controller controls the driving motor 2 to operate, so that the output end of the driving motor 2 rotates to drive the first roller 3 to roll, so that the surface of the first roller 3 is contaminated with colloid due to contact with the glue brush 6. The connecting frame 17 is moved, so that the connecting frame 17 drives the slider 18 to move along the inner side of the slide groove 15 through the moving frame 19. At the same time, the connecting frame 17 can drive the limit plate 11 to move under the support of the elastic force of the spring 10. The moving frame 19 is elastically supported by the inner rod 20 under the torsion spring 22. The clamping block 21 is driven to move along the serrated plate 16 under the support of force, and the position of the limiting plate 11 is adjusted according to the corrugated cardboard to be glued, so that the clamping block 21 is clamped at the appropriate position of the serrated plate 16, and the clamping block 21 is fixed by the abutment bolt 24 to fix the limiting plate 11. The staff places the stacked corrugated cardboard between the two limiting plates 11 on the top of the conveying frame 7, and controls the conveying frame 7 to operate, so that the conveying frame 7 can drive the corrugated cardboard stacked at the bottom to move between the first roller 3 and the second roller 4, so that the first roller 3 can apply the colloid on the corrugated cardboard, and the first roller 3 cooperates with the second roller 4 to move the applied colloid to the workbench 1, thereby completing the gluing work.
