These packages are usually packaged in cardboard boxes, so the demand for cardboard boxes is also increasing. In the production process of cardboard boxes, cardboard needs to be glued together, so a cardboard gluing device is needed.

[0003] Most existing cardboard bonding devices require manual operation to rotate the bottom cardboard for bonding, which is labor-intensive, inefficient, and cannot guarantee the quality of the cardboard boxes, thus hindering the use of the device and the production of cardboard boxes. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as the fact that most machines require manual operation, resulting in high labor intensity, low efficiency, and inconsistent quality of cardboard boxes, which is detrimental to the use of the device and the production of cardboard boxes. Therefore, this utility model proposes a cardboard bonding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A cardboard bonding device, comprising:

[0020] A fixed base plate 1 is rotatably connected to the top of the fixed base plate 1, and a fixed plate 2 is fixedly connected to the top of the connecting shaft 13. A placement groove 3 is opened at the top of the fixed plate 2. A fixed shaft 4 is rotatably connected to the top of the fixed base plate 1. A driver is installed on the fixed shaft 4. A threaded rod 5 is fixedly connected to the top of the fixed shaft 4. A threaded block 6 is threadedly connected to the threaded rod 5. Connecting plates 7 are provided on both the front and rear sides of the fixed shaft 4, and the connecting plates 7 are fixedly connected to the fixed base plate 1. The threaded block 6 is slidably connected to the connecting plate 7. A feeding structure is fixedly installed at the end of the threaded block 6 near the fixed base plate 1. A cardboard is placed inside the feeding structure.

[0021] The driver drives the fixed shaft 4 to rotate. When the fixed shaft 4 rotates, it will drive the threaded rod 5 to rotate as well, while the threaded block 6 cannot rotate. Therefore, under the action of the thread, the rotation of the threaded rod 5 will cause the threaded block 6 to move, which will drive the feeding structure to move as well, and perform the bonding of the cardboard.

[0022] The feeding structure includes a connecting block 8 fixedly connected to the side wall of the threaded block 6. A mounting plate 9 is fixedly connected to the end of the connecting block 8 away from the threaded block 6. A feeding box 10 is fixedly installed on the mounting plate 9. A feeder is fixedly installed inside the feeding box 10. The feeder is existing equipment and will not be described in detail in this text. A feeding port is opened on the lower inner wall of the feeding box 10. The position of the feeding port corresponds to the fixed plate 2. When the threaded block 6 moves, the connecting block 8 and the mounting plate 9 move with it, driving the feeding box 10 to move together. When the feeding box 10 moves down to the placement groove 3, the cardboard falls from the feeding port for cardboard bonding. A fixed cover plate 11 is rotatably connected to the top of the feeding box 10 through a rotating shaft. Opening the fixed cover plate 11 allows feeding into the feeding box 10.

[0023] The fixed shaft 4 and the connecting shaft 13 are connected to each other via a belt drive structure 12. An adjusting ring 14 is fixedly connected to the top of the belt drive structure 12, and the adjusting ring 14 is sleeved on the outside of the connecting shaft 13. An adjusting groove is formed at the top of the adjusting ring 14, and a connecting ratchet 15 is fixedly connected to the inner wall of the adjusting groove. A connecting ratchet 16 is rotatably connected to the side wall of the connecting shaft 13 via a one-way bearing, and the connecting ratchet 16 matches the connecting ratchet 15. Therefore, the connecting ratchet 16 can only rotate in one direction. Figure 3 For reference, when the connecting ratchet 15 rotates clockwise, the connecting ratchet 16 will engage with the connecting ratchet 15. At this time, the rotation of the connecting ratchet 15 will drive the connecting ratchet 16 to move, thereby driving the connecting shaft 13 to rotate. However, rotating counterclockwise will not cause the connecting ratchet 16 to move.

[0024] Under the action of the belt drive structure 12, the rotation of the fixed shaft 4 will drive the connecting shaft 13 to rotate, thereby causing the fixed plate 2 to rotate as well. The fixed plate 2 will eventually rotate to a position 1 / 4 turn away from its original position, so as to facilitate the bonding of the cardboard.

[0025] A sliding block is fixedly connected to the side wall of the threaded block 6, and a sliding groove matching the sliding block is opened on the side wall of the connecting plate 7 to facilitate the movement of the threaded block 6; a limit block is fixedly installed at the top of the threaded rod 5, and the driver is a bidirectional motor that can rotate forward and reverse.

[0026] In this invention, when using the device, the bottom cardboard is first placed into the placement groove 3, glue is applied, and then the driver is started. The output end of the driver drives the fixed shaft 4 to rotate, thereby causing the threaded rod 5 to rotate. Since the threaded block 6 cannot rotate, the rotation of the threaded rod 5 under the action of the thread will cause the threaded block 6 to move downward, driving the connecting block 8 and the mounting plate 9 to move, and driving the feeding box 10 to move together. When the feeding box 10 moves downward to the placement groove 3, the cardboard falls from the feeding port for bonding. At the same time, the driver rotates in the opposite direction, causing the feeding box 10 and other structures to move upward, allowing the cardboard to completely separate from the feeding box 10. During the upward movement of the feeding box 10, the rotation of the connecting ratchet 15 will drive the connecting ratchet 16 to move, thereby driving the connecting shaft 13 to rotate. Therefore, under the action of the belt drive structure 12, the rotation of the fixed shaft 4 will drive the connecting shaft 13 to rotate, thereby causing the fixed plate 2 to rotate as well. The fixed plate 2 will eventually rotate to a position 1 / 4 turn away from its original position to facilitate the bonding of the cardboard.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
