However, the disassembly and assembly of the existing glue coating roller is too cumbersome and not simple enough, resulting in time-consuming and labor-intensive disassembly and assembly of the glue coating roller, which affects the work efficiency of replacing the glue coating roller. Therefore, it is necessary to design a glue coating device for printing and packaging production. Summary of the invention

At the mouth, the inner side wall of the movable frame 4 is fixedly connected with a mounting seat 14 and a second motor 8, the output shaft end of the second motor 8 is fixedly connected with the glue roller 9, the front end face of the mounting seat 14 is provided with a U-shaped mounting groove 17, the inside of the U-shaped mounting groove 17 is provided with a fixed shaft 12, the circumferential surface of the fixed shaft 12 is rotatably connected with a glue coating roller 11, the glue coating roller 11 is located at the lower end of the glue roller 9, the upper end face of the mounting seat 14 is provided with a sliding hole 18, the inside of the sliding hole 18 is slidably connected with a baffle 20, the baffle 20 is located at the front end of the fixed shaft 12, and is used to block the fixed shaft 12. When in use, the operation of the first motor 2 can drive the front end transmission roller 13 to rotate. At this time, with the cooperation of the rear end transmission roller 13, the conveyor belt 3 is rotated. With the rotation of the conveyor belt 3, the printed packaging products on the conveyor belt 3 can be transported backward. At the same time, the operation of the second motor 8 can drive the glue roller 9 to rotate. The glue roller 9 can dip the glue inside the glue box 7 and apply it on the circumferential surface of the glue roller 11. Until the printed packaging product moves to the lower end of the glue roller 11, the glue roller 11 can apply glue to the upper end of the printed packaging product.

[0024] During operation, by pulling the baffle plate 20 to move along the sliding hole 18, the baffle plate 20 gradually moves in the direction away from the fixed shaft 12 until the baffle plate 20 is completely disengaged from the fixed shaft 12. The glue coating roller 11 can be directly removed from the mounting seat 14 and replaced. When replacing the glue coating roller 11, it is only necessary to insert the fixed shaft 12 into the U-shaped mounting groove 17, and then use the baffle plate 20 to block the front end of the fixed shaft 12. In this way, the installation of the glue coating roller 11 is completed. This method of disassembling and assembling the glue coating roller 11 is not only simple, fast, time-saving and labor-saving, but also more efficient.

[0025] Furthermore, a sliding groove 19 is provided on the front end surface of the mounting seat 14, and a sliding block 21 is slidably connected inside the sliding groove 19. The sliding block 21 is fixedly connected to the baffle 20. The front end of the mounting seat 14 is fixedly connected to a sliding rod 24 through a fixed plate. The sliding rod 24 passes through the sliding block 21, and the sliding block 21 is slidably connected to the sliding rod 24. A spring 22 is provided between the sliding block 21 and the fixed plate, one end of the spring 22 is fixedly connected to the fixed plate, and the other end of the spring 22 is fixedly connected to the sliding block 21. During operation, when the baffle 20 is controlled to move along the sliding hole 18 in the direction away from the fixed shaft 12, the sliding block 21 will be driven to move along the sliding groove 19 and the sliding rod 24, and the spring 22 will be compressed until the baffle 20 is completely separated from the fixed shaft 12, and the fixed shaft 12 and the glue coating roller 11 can be removed from the mounting seat 14. When installing a new fixed shaft 12 and the glue coating roller 11, the fixed shaft 12 is installed into the U-shaped mounting groove 17. At this time, the baffle 20 is released. Under the action of the spring 22, the baffle 20 can be moved in the direction close to the fixed shaft 12, so that the baffle 20 is tightly blocked at the front end of the fixed shaft 12. At this time, under the action of the spring 22, the baffle 20 can be more stably located at the front end of the fixed shaft 12, and it is not easy to move at will, which affects the stability of the installation of the fixed shaft 12.

[0026] Furthermore, the lifting assembly includes a threaded rod 6, a movable support plate 5 and a bearing plate 10. The left and right ends of the fixed frame 1 are fixedly connected with the bearing plate 10. The inner part of the bearing plate 10 is rotatably connected with the threaded rod 6. The circumferential surface of the threaded rod 6 is threadedly connected with the movable support plate 5. The movable support plate 5 is fixedly installed at the lower end of the movable frame 4. During operation, the threaded rod 6 rotates, so that the movable support plate 5 can drive the movable frame 4 to perform lifting operations, and then drive the glue box 7, the glue roller 9 and the glue coating roller 11 to perform lifting operations. At this time, the distance between the glue coating roller 11 and the conveyor belt 3 gradually changes, so that the glue coating roller 11 can be used to glue the printed packaging products of different thicknesses on the conveyor belt 3.

[0027] Furthermore, the lower end of the threaded rod 6 is fixedly connected with a driven wheel 15, the lower end of the fixed frame 1 is fixedly connected with a support frame 27, the internal rotation of the support frame 27 is connected with two driving wheels 25 which are symmetrically distributed on the left and right sides, the two driving wheels 25 are connected by a second belt 23, the lower end of the support frame 27 is fixedly connected with a third motor 26, the output shaft end of the third motor 26 is fixedly connected with the driving wheel 25 at the left end, and the two driving wheels 25 are respectively connected with the driven wheels 15 at the left and right ends through the first belt 16. When working, the third motor 26 can drive the driving wheel 25 at the left end to rotate, and at this time, with the cooperation of the second belt 23, the driving wheel 25 at the right end is driven to rotate. Since the two driving wheels 25 rotate at the same time, with the cooperation of the first belt 16, the driven wheels 15 can be rotated at the same time, and then each threaded rod 6 can be rotated at the same time.

[0028] Furthermore, the thread shape of the circumferential surface of the threaded rod 6 is triangular. During operation, the triangular thread has self-locking property, and when the threaded rod 6 does not rotate, the movable support plate 5 can be stably located on the circumferential surface of the threaded rod 6 without moving arbitrarily.

[0029] Further, a stopper is fixedly connected to the upper end of the threaded rod 6, and the diameter of the stopper is larger than the diameter of the threaded rod 6. During operation, the existence of the stopper blocks the movable support plate 5, so that the movable support plate 5 will not be separated from the threaded rod 6.
