Description

Technical Field

[0002] In the packaging and printing industry, the application of the box gluing machine is the last step in the packaging box processing. It folds the printed and die-cut cardboard into shape and glues the edges. The machine replaces the manual box gluing method, reducing labor costs and improving efficiency.

[0003] Currently, most box gluing machines are equipped with a paper feeding mechanism and a twisting guide rail. The twisting guide rail is a long strip that is gradually twisted 180°. The paper feeding mechanism drives the paper box to move along the twisting guide rail, thereby gradually bending and folding the paper box.

[0004] With respect to the above-mentioned related technologies, the inventors believe that if the pre-pressing indentation is not clear during the folding process of the paper box, it may cause inaccurate folding of the paper box, resulting in a defect of low product yield. Summary of the Invention

[0005] In order to improve the yield of products, the present application provides a folding mechanism for a folder gluing machine.

[0006] The folding mechanism of a folder-gluing machine provided in this application adopts the following technical solution:

[0007] A folding mechanism of a box gluing machine includes a frame, on which a conveyor belt for transporting paper boxes is installed, a pressure plate is arranged in the horizontal direction inside the frame, a support seat is fixedly provided between the pressure plate and the ground, and a surface of the pressure plate facing away from the support seat is provided with an avoidance groove for the conveyor belt to pass through, folding platforms are provided on both sides of the pressure plate, and storage grooves are provided on the opposite side walls of the two folding platforms, a folding plate is provided in the storage groove, one end of the folding plate passes through the storage groove and extends to the outside of the folding platform, a roller is rotatably connected inside the folding plate, both ends of the roller are fixedly connected to the folding platform, a driving component for driving the folding plate to rotate is provided on the upper surface of the folding platform, and a pressing component for pressing the paper box is provided on the side of the pressure plate facing away from the support seat.

[0008] By adopting this technical solution, the pressing assembly presses the indentation of the carton against the pressure plate, while the driving assembly rotates the hemming plate, which lifts the edge of the carton during rotation to pre-fold it. Through this structure, the pressing assembly and hemming plate cooperate to pre-fold the indentation of the carton again, making it clearer, thereby improving the accuracy of the hemming and increasing the yield rate of the product.

[0010] By adopting the above technical solution, the drive motor starts to rotate the drive rod through the first and second gears, which in turn rotates the pressing block. The pressing block presses the hemming plate through the trigger rod, causing the hemming plate to rotate around the rotating roller. The hemming plate thus lifts the edge of the paper box to pre-fold. After the pre-fold, the output shaft of the drive motor changes its direction of rotation, and the torsion spring releases its elastic force, causing the hemming plate to rotate and reset, thereby waiting for the next pre-fold.

When the hemming plate lifts and pre-folds the carton, the pressure block moves closer to the plate until it presses the indented area of ​​the carton against the plate. When the hemming plate rotates and resets, the pressure block moves away from the plate. This structure achieves the effect of the reciprocating motion of the pressure block pressing the carton tightly.

[0014] By adopting the above technical solution, the driving rod rotates to rotate the transmission rod, and the transmission rod rotates the threaded sleeve through the first bevel gear and the second bevel gear, thereby achieving the effect of the transmission assembly driving the threaded sleeve to rotate.

[0015] Optionally, a sliding groove is provided on the end face of the drive rod facing the threaded sleeve, the transmission rod is arranged in the sliding groove, the side wall of the transmission rod is fixed with a first guide block, and the inner wall of the drive rod at the sliding groove is provided with a first guide groove that is slidably adapted to the first guide block.

[0016] By adopting the above technical solution, the driving rod rotates the transmission rod through the first guide block, thereby driving the motor to drive the threaded sleeve to rotate; when adjusting the distance between the folding table and the movable seat, the transmission rod slides along the slide groove to make the first guide block slide along the first guide groove, thereby the total length of the transmission rod and the linkage rod can be adjusted.

[0019] Optionally, a bidirectional screw is provided between the two movable seats, the movable seat and the bidirectional screw are threadedly connected, and the two movable seats are respectively arranged on the two sections of the thread of the bidirectional screw, and a hanging plate is provided on the opposite side of the two movable seats, and the hanging plate and the bidirectional screw are rotatably connected, a first limit rod is fixed between the two hanging plates, the first limit rod passes through the movable seat, and a connecting frame is fixed between the hanging plate and the frame, the side walls of the two hanging plates facing away from each other are rotatably connected with an adjusting screw, the circumferential side walls of the adjusting screw are threadedly connected with an adjusting sleeve, the adjusting sleeve is fixedly connected to the support plate, and the side walls of the two hanging plates facing away from each other are fixed with a second limit rod, and the second limit rod passes through the adjusting sleeve.

[0020] By adopting the above technical solution, the operator rotates the bidirectional screw to move the two movable seats toward or away from each other, thereby adjusting the position of the pressure block through the movable seats; the operator rotates the adjustment screw to move the adjustment sleeve closer to or away from the hanging plate, thereby adjusting the position of the hemming plate through the adjustment sleeve.

[0022] By adopting the above technical solution, the linkage assembly rotates the linkage roller, which in turn rotates the shaft via the third and fourth bevel gears, which in turn rotates the edge-pressing block. When the edge-pressing block moves away from the pressure plate, the shaft moves the edge-pressing block closer to the pre-folded edge of the carton, allowing the edge-pressing block to press the pre-folded edge again. When the edge-pressing block approaches the pressure plate, the shaft moves the edge-pressing block away and rotates back to its original position, allowing the edge-pressing block to wait for the next press on the pre-folded edge.
