[0002] A carton stapler is a special device that can form cardboard into a box body and staple the formed box body to final shape. The cardboard conveying mechanism is an important component of the carton stapler. The traditional cardboard conveying mechanism includes two placement racks. The cardboard is placed on the two placement racks for transportation and is formed and stapled during the transportation process. At present, the placement racks on the market are generally fixed. However, in actual use, the specifications of the cartons will change. In order to improve the quality of carton forming, the two placement racks need to be adjusted, and the two placement racks must be kept flush during the adjustment process. If traditional guide posts, guide rails and other structures are used, the guide posts and guide rails will inevitably pass through the placement racks, which will collide with the bent part of the cardboard. This traditional guide structure is not suitable for the placement rack guide of the carton stapler. Utility Model Content

[0022] As shown in the figure, the utility model discloses a cardboard conveying mechanism of a box nailing machine, including a first placement rack 1 arranged on a frame, a second placement rack 5 is arranged on one side corresponding to the first placement rack 1, the spacing between the first and second placement racks can be adjusted, and a push plate assembly is provided on the corresponding placement rack, and also includes a first support rod 7 and a second support rod 11, one end of the first support rod 7 is fixed on the first placement rack 1, and one end of the second support rod 11 is fixed on the second placement rack 5, and the first and second support rods both pass through the locking assembly. When the locking assembly is locked, the first and second support rods cannot move relative to the locking assembly. When the locking assembly is released, the first and second support rods can move relative to the locking assembly.

[0023] Furthermore, the locking assembly includes a locking seat 10, on which a locking block 13 is provided. The locking block 13 is connected to the movable driving assembly. The movable driving assembly can drive the locking block 13 to move, thereby locking the support rod passing through the locking seat. The locking block can be tightly pressed against the side wall of the support rod, and the support rod can be locked by friction.

[0024] Furthermore, the movable drive assembly includes a first cylinder 12, the cylinder body of the first cylinder 12 being disposed on the locking seat 10, and the piston rod of the first cylinder 12 being connected to the locking block 13. Of course, in addition to using a cylinder, a common drive structure such as a hydraulic cylinder, a linear motor, a synchronous belt drive group, a cam drive group, etc. can also be used to drive the locking block 13 to move. The movement of the locking block is not limited to linear movement, and can also swing, rotate, etc., as long as the locking block 13 can be moved to cooperate with the support rod to lock.

[0025] Furthermore, a paperboard support 3 is provided on the locking seat 10. The paperboard in the suspended portion can be supported to further improve the stability of the paperboard conveying.

[0026] Furthermore, the first support rod 7 and the second support rod 11 are both provided with an anti-slip member 9, which can abut against the locking assembly to prevent the first and second support rods from separating from the locking assembly, thereby ensuring the stability of the locking assembly during use.

[0027] Furthermore, the first support rod 7 and the second support rod 11 are in the shape of polygonal columns, so that the locking block 13 can be pressed against the side walls of the support rods in a surface-fitting manner, effectively increasing the friction during locking and ensuring the firmness of the locking.

[0028] Furthermore, it includes an intermediate support rod 8, which passes through one locking assembly with the first support rod 7, and passes through another locking assembly with the second support rod 11. The locking assembly can also lock the position of the intermediate support rod 8. By adopting the above structure, the maximum distance between the first and second placement racks can be further increased due to the addition of the intermediate support rod, and when all support rods are in the retracted state, the minimum distance between the first and second placement racks can also be made smaller, which can accommodate the molding of more cartons of different specifications.

[0029] Furthermore, multiple sets of intermediate support rods 8 are included. The first support rod 7 and one of the intermediate support rods 8 pass through a corresponding locking assembly, the second support rod 11 and another of the intermediate support rods 8 pass through a corresponding locking assembly, and adjacent intermediate support rods 8 pass through a corresponding locking assembly. The locking assembly can also lock the position of the intermediate support rods. With this structure, the number of intermediate support rods 8 is further increased, making the maximum spacing between the first and second placement racks larger and the minimum spacing smaller.

[0030] Furthermore, the push plate assembly includes a first conveyor belt 2 mounted on a first rack 1 and a second conveyor belt 4 mounted on a second rack 5. Both the first and second conveyor belts are equipped with push plates. A drive motor 6, via its output shaft, rotates the corresponding conveyor pulleys, thereby driving both conveyor belts. This structure allows the first and second racks to adjust their spacing based on the carton specifications, while simultaneously adjusting the positions of the first and second conveyor belts, ensuring more stable and reliable movement of the cartons.

[0031] Taking the arrangement of multiple intermediate support rods 8 as an example, the working principle of the present invention is as follows: when it is necessary to adjust the spacing between the first and second racks 1 and 5, the first cylinder 12 on one of the locking seats 10 is controlled to drive the locking block 13 to separate from the first support rod 7 and the intermediate support rod 8. At this time, when the second rack 5 is driven to move, the first support rod 7 and the intermediate support rod 8 can move relative to the locking seat. When the adjustment is in place, the first cylinder 12 is controlled to drive the locking block 13 to move and press against the first support rod 7 and the intermediate support rod 8 to lock them. If only one set of locking components is loosened and the spacing between the first and second racks cannot be adjusted in place, then another or other two locking components are loosened, so that the second support rod 11 and the other intermediate support rods can slide relative to the locking components, thereby increasing the moving space of the second rack 5 and allowing the second rack 5 to move to a suitable position, thus completing the spacing adjustment between the first and second racks.

[0032] The structure of the present invention is provided with a support rod and a locking assembly, and the locking assembly and the support rod are both located between the first and second placement racks. When the spacing between the first and second placement racks needs to be adjusted, it is only necessary to loosen the locking assembly. At this time, the support rod can move relative to the locking assembly, thereby guiding and supporting the movement of the placement racks, so that the two placement racks can still remain flush after the spacing is adjusted, thereby ensuring the molding quality of the carton.
