Description

Technical Field

[0001] This utility model relates to the technical field of press-fit gluing machines, specifically a press-fit gluing machine for carton production. Background Technology

[0002] The pressing and gluing machine is a type of equipment used for gluing and forming cartons. It is mainly suitable for small and medium batches of cartons with multiple varieties. Its core components include a paper feeding and correction section and a crease shaping and gluing section. The paper feeding and correction section is used to ensure that the cardboard is accurately positioned when entering the next process, while the crease shaping and gluing section is responsible for completing the creasing, gluing and gluing work of the cartons.

[0003] Common press-fit gluing machines typically have an adhesive coating section at the top. After manual folding and alignment at the ends, the machine is inserted between two conveyor belts at the bottom for compression to ensure adhesion stability. During this process, excessive compression can damage the carton, especially the corrugated parts inside the corrugated carton. Excessive compression can cause the corrugated parts to lose their original cushioning structure, and excessive compression can also affect the normal transport of the conveyor belt. Insufficient compression will cause the glued parts to loosen, failing to achieve the desired pressing effect. Therefore, it is necessary to design a press-fit gluing machine with an adjustable structure. Utility Model Content

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a bottom support 1 for a gluing machine, an upper conveyor belt 2 and a bottom conveyor belt 3 installed inside the bottom support 1, a drive roller 31 and an adjusting roller 32 respectively installed at both ends of the bottom conveyor belt 3, a drive motor that drives the drive roller 31 to rotate is installed on the outside of the bottom support 1, a folding table 11 is fixed at the end of the bottom support 1, a center plate 4 is fixed inside the bottom support 1 and located in the middle of the bottom conveyor belt 3, a lifting groove 6 is opened at the center of the upper end of the center plate 4, a lifting plate 5 is installed in the lifting groove 6, and a drive component for driving the lifting plate 5 to rise and fall is provided at the bottom of the lifting groove 6.

[0019] The drive assembly includes an angled groove 51 and a trapezoidal plate 62. The angled groove 51 is located at the bottom of the lifting plate 5 and is symmetrically distributed. The trapezoidal plate 62 is slidably connected to the bottom of the lifting groove 6 and aligned with the angled groove 51. Limiting rods 61 are fixed at the four corners of the bottom of the lifting plate 5. The limiting rods 61 are slidably connected to the bottom of the lifting groove 6. A pull-down spring is fixed between the bottom of the lifting groove 6 and the lifting plate 5. The pull-down spring is located outside the limiting rods 61. A pair of guide rails 64 are fixed at the bottom of the lifting groove 6. The trapezoidal plate 62 is slidably connected to the guide rails 64. A servo motor 65 is fixed on the side of the center plate 4 near the drive roller 31. The output end of the servo motor 65 is fixed on the bidirectional lead screw 63.

[0020] A telescopic frame 73 is installed on the side of the center plate 4 near the adjusting roller 32. The telescopic frame 73 has a U-shaped structure. The adjusting roller 32 is rotatably connected inside the telescopic frame 73. An adjusting groove 7 is opened in the center plate 4. The telescopic frame 73 passes through the adjusting groove 7. A threaded rod 71 is rotatably connected in the adjusting groove 7. The threaded rod 71 passes through the telescopic frame 73 and is threadedly connected to the telescopic frame 73. The end of the threaded rod 71 is fixedly connected to the bidirectional lead screw 63. A pair of guide rods 72 are fixed in the adjusting groove 7.

[0021] Working Principle: First, connect the entire device to an external power source. Place the folded carton between the upper conveyor belt 2 and the bottom conveyor belt 3. The carton is conveyed through the gap between the upper and bottom conveyor belts 2 and 3. During this process, the two conveyor belts compress the carton, ensuring the bonded areas do not loosen, thus achieving the purpose of pressing. The smaller the distance between the upper and bottom conveyor belts 2 and 3 on their closest sides, the greater the compression force on the carton. Therefore, when the lifting plate 5 moves up and down, the pressure can be adjusted. This process utilizes a servo motor. The drive at the output end of 65 can rotate the threaded rod 71, causing the trapezoidal plate 62 to slide synchronously in opposite directions. When sliding to the side away from each other, the trapezoidal plate 62 can lift the lifting plate 5, and conversely, the pull-down spring can pull the lifting plate 5 downward, easily achieving the purpose of lifting and adjusting. During the adjustment process, the rotation of the bidirectional screw 63 will drive the threaded rod 71 to rotate synchronously, thereby driving the telescopic frame 73 to telescopically move, changing the distance between the drive roller 31 and the adjusting roller 32, thus ensuring the stable conveying tension of the bottom conveyor belt 3.
