Description

Technical Field

[0001] This utility model relates to the field of box gluing machine technology, and in particular to an adjustable box gluing machine for printing and packaging. Background Technology

[0002] In the packaging and printing industry, the application of box gluing machines is the final step in packaging box processing. It involves folding and gluing printed and die-cut cardboard into shape. Machine gluing replaces manual gluing, reducing labor costs and improving efficiency.

[0003] The guide rails are key components in a carton gluing machine used to control the conveying of cartons. There are two guide rails, one on each side, positioned above the conveyor belt. Their function is to ensure the cartons maintain the correct position and orientation during transport, preventing offset or misalignment, thus guaranteeing the quality and efficiency of gluing. In existing technology, when gluing cartons of various sizes, the spacing of the guide rails needs to be adjusted according to the dimensions of the flattened cartons. However, the current adjustment method is manual. Since the guide rails are relatively long, manual adjustment requires step-by-step adjustment of both ends of the two guide rails. Furthermore, the different spacing between the two ends causes the guide rails to form a flared shape, which can cause cartons to fall during transport. To avoid these problems, multiple adjustments are required, wasting considerable time and reducing operational convenience. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable gluing machine for printing and packaging.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable box gluing machine for printing and packaging, comprising two conveying sections, a frame, and two pull gauges. The two pull gauges are mounted on the top of the frame, and two gears are provided above both ends of the two pull gauges. The surfaces of the four gears are meshed with racks, and two adjacent racks are positioned above and below the gears. One end of each of the four racks is mounted on both ends of the two pull gauges, and a stepper motor is installed between the four gears through a transmission mechanism.

[0006] Preferably, the transmission mechanism includes two bevel gears and a transmission shaft. The four gears are respectively fixedly sleeved on both ends of the transmission shaft, and the two bevel gears are respectively fixedly sleeved on the surface of the transmission shaft and the movable end of the stepper motor, and the two bevel gears mesh.

[0007] Preferably, both ends of the two pull gauges are equipped with connecting rods, and one end of each of the four racks is respectively mounted on the surface of the four connecting rods.

[0008] Preferably, a fixing block is provided above the top of each of the two adjacent connecting rods, and a connecting plate is installed between the two fixing blocks. The stepper motor is installed on the top of the connecting plate, and the movable end of the stepper motor is installed through the surface of the connecting plate. An elongated hole is opened on the surface of the fixing block, and a fixing rod is installed inside the elongated hole. The top of each of the two adjacent connecting rods is sleeved on the surface of the fixing rod. Support rods are installed at both ends of the fixing block, and one end of each of the two support rods is installed on the surface of the frame.

[0009] Preferably, each of the four connecting rods has a support block mounted on its side, and the top of the support block contacts the bottom of the rack.

[0010] Preferably, one end of one of the support blocks is equipped with an installation block, the side of the installation block has an installation groove, a screw is installed inside the installation groove, a connecting block is movably sleeved on the surface of the screw, one end of the connecting block extends above the rack, a limiting tooth block is installed on one end of the connecting block, the limiting tooth block is inserted into the tooth groove of the rack, a compression spring is sleeved on the surface of the screw, the two ends of the compression spring are respectively installed on the surface of the connecting block and the installation groove, a threaded tube is threaded on the surface of the screw, and the bottom of the threaded tube contacts the top of the connecting block.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] like Figure 1-6 The adjustable gluing machine for printing and packaging shown includes two conveying sections 1, a frame 2, and two pull gauges 3. The pull gauges 3 are usually located at the end of the feeding conveyor in the gluing machine, while the feeding conveyor is installed on the top of the frame 2. At the same time, the feeding conveyor and the two conveying sections 1 are at the same height, which facilitates the transfer of paper boxes between the two pull gauges 3. The two pull gauges 3 are installed above the frame 2, and the two conveying sections 1 are both installed on the top of the frame 2. The bottoms of the two pull gauges 3 are respectively installed on the top of the conveying section 1. The conveying section 1 consists of a support, a motor, a belt conveyor pulley, and a conveyor belt, and is used to drive the flattened paper boxes to be transported between the two pull gauges 3.

[0024] Two gears 5 are provided above each end of the two pull gauges 3. The surfaces of the four gears 5 are meshed with racks 13. The racks 13 of each pair are positioned above and below the gears 5. One end of each rack 13 is installed at the end of the two pull gauges 3. A stepper motor 8 is installed between the four gears 5 through a transmission mechanism. The transmission mechanism includes two bevel gears 7 and a transmission shaft 10. The four gears 5 are fixedly sleeved on both ends of the transmission shaft 10. The two bevel gears 7 are fixedly sleeved on the surface of the transmission shaft 10 and the movable end of the stepper motor 8, respectively. The two bevel gears 7 mesh, and the stepper motor 8 drives the transmission shaft 10 to rotate through the two bevel gears 7. The transmission shaft 10 drives the four gears 5 to rotate synchronously. The four gears 5 drive the four racks 13 to move horizontally. By controlling the distance between adjacent racks 13, it is convenient to control the synchronous movement of the ends of the two pull gauges 3. It is also convenient to adjust the distance between the two pull gauges 3 according to the size of the cardboard box after it is laid flat, saving a lot of time and improving the convenience of operation.

[0025] Both ends of the two pull gauges 3 are equipped with connecting rods 4. One end of each of the four racks 13 is mounted on the surface of the four connecting rods 4. A fixing block 12 is provided above the top of each of the two adjacent connecting rods 4. A connecting plate 6 is installed between the two fixing blocks 12. A stepper motor 8 is mounted on the top of the connecting plate 6. The movable end of the stepper motor 8 is mounted through the surface of the connecting plate 6. The surface of the fixing block 12 has an elongated hole 9. A fixing rod 23 is installed inside the elongated hole 9. The top of each of the two adjacent connecting rods 4 is fitted onto the surface of the fixing rod 23. Support rods 14 are installed at both ends of the fixing block 12. One end of each of the two support rods 14 is mounted on the surface of the frame 2. The fixing blocks 12 are used to support the stepper motor 8, improving the stability of the stepper motor 8. As the racks 13 drive the connecting rods 4 to move, the top of the connecting rods 4 slides on the surface of the fixing rods 23, improving the stability of the pull gauge 3 during horizontal movement. The two support rods 14 provide stable support for the fixing blocks 12.

[0026] Support blocks 18 are installed on the sides of the four connecting rods 4. The top of the support block 18 contacts the bottom of the rack 13. When one of the connecting rods 4 drives the rack 13 to move, the other end of the rack 13 moves to the top of the support block 18 on the other connecting rod 4, which improves the stability of the rack 13 during horizontal movement.

[0027] One end of one of the support blocks 18 is fitted with a mounting block 15. A mounting groove is formed on the side of the mounting block 15, and a screw 20 is installed inside the mounting groove. A connecting block 11 is movably fitted onto the surface of the screw 20. One end of the connecting block 11 extends above the rack 13, and a limiting tooth block 21 is installed at one end of the connecting block 11. The limiting tooth block 21 is inserted into the tooth groove of the rack 13. A compression spring 22 is fitted onto the surface of the screw 20, with its two ends respectively mounted on the surfaces of the connecting block 11 and the mounting groove. A threaded tube 17 is threaded onto the surface of the screw 20, with the bottom of the threaded tube 17 contacting the top of the connecting block 11. After adjusting the spacing between the two pull gauges 3, the threaded tube 17 needs to be rotated. The threaded tube 17 rotates on the surface of the screw 20. This allows the solenoid 17 to push the connecting block 11 to move on the surface of the screw 20. At the same time, the connecting block 11 presses down on the compression spring 22. After the compression spring 22 is subjected to force, its length contracts. This allows the connecting block 11 to drive the limiting tooth block 21 to move into the tooth groove of the rack 13. At this time, the position of a single rack 13 is limited, which is used to limit the four gears 5 and improve the stability between the two pull gauges 3. Before adjusting the distance between the two pull gauges 3, the solenoid 17 needs to be rotated in the opposite direction. After the solenoid 17 moves away from the connecting block 11, the compression spring 22 pushes the connecting block 11 upward through its own elastic potential energy. This makes it easier for the connecting block 11 to drive the limiting tooth block 21 to move out of the tooth groove of the rack 13, which facilitates the movement of the four gears 5 and the four racks 13.

[0028] Multiple dovetail groove blocks 16 are installed on the side of the conveying unit 1. Dovetail blocks 19 are matched in the dovetail grooves of the dovetail groove blocks 16. The top of the dovetail block 19 is installed on the bottom of the pull gauge 3. The dovetail groove blocks 16 are installed on the side of the support member. When the pull gauge 3 moves, the dovetail blocks 19 can slide in the dovetail grooves, which plays a guiding role in the movement of the pull gauge, prevents the pull gauge 3 from shifting its position when moving, and improves the stability of the pull gauge 3 when moving.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
