Description

Technical Field

[0001] This utility model relates to the field of molding device technology, specifically to a molding mechanism for biodegradable corrugated cardboard. Background Technology

[0002] Biodegradable corrugated cardboard is an environmentally friendly material, mainly made of biodegradable paper materials. Compared with traditional corrugated cardboard, it uses biodegradable pulp and environmentally friendly glue, and can degrade naturally in a short time after use, reducing the burden on the environment.

[0003] During the production of corrugated cardboard, a molding mechanism is used to crease the cardboard. Currently, traditional molding mechanisms are difficult to adjust the crease spacing flexibly. When dealing with corrugated cardboard of different specifications, workers need to replace the corresponding parts to carry out production and processing. This method is cumbersome, increases downtime, and reduces production efficiency. Utility Model Content

When dealing with corrugated cardboard of different specifications, workers need to replace the corresponding parts to carry out production and processing. This method is cumbersome to operate, increases downtime, and reduces production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0020] Reference Figure 1 As shown, a molding mechanism for biodegradable corrugated cardboard includes a workbench 1, a mounting base 2 fixedly connected to the top of the workbench 1, a conveyor belt 3 fixedly mounted on the top of the mounting base 2, a limiting component 4 below the mounting base 2, a bracket 5 fixedly connected to the top of the workbench 1, a pair of first cylinders 6 fixedly mounted on the top of the bracket 5, the output end of the first cylinder 6 passing through the top of the bracket 5 and fixedly connected to a lifting frame 7, an adjusting component 8 inside the lifting frame 7, a pair of sliding grooves 71 at the bottom of the lifting frame 7, telescopic sleeve rods 9 slidably mounted inside both sliding grooves 71, pressure rollers 10 fixedly mounted on the lower end of the telescopic sleeve rods 9, and a sleeve on the lower surface of the telescopic sleeve rods 9. The damping spring 91 has its lower end fixedly connected to the top of the pressure roller 10, and its other end fixedly connected to the upper part of the telescopic sleeve rod 9. In use, the biodegradable corrugated cardboard is placed on the conveyor belt 3. By adjusting the cooperation between the rotating plate 81 and the connecting rod 82 in the adjusting assembly 8, the transmission block 83 drives the telescopic sleeve rod 9 to move. The distance between the two pressure rollers 10 is adjusted according to the creasing requirements of the cardboard. The guide plate 43 in the limiting assembly 4 drives the limiting baffle 44 to limit the cardboard. The lifting frame 7 drives the pressure rollers 10 to descend and creasing the cardboard. No parts need to be replaced for different specifications of corrugated cardboard, making it more flexible and improving production efficiency.

[0021] Furthermore, such as Figure 2 and Figure 3As shown, the adjusting assembly 8 includes a rotating plate 81, a pair of transmission blocks 83, and a second cylinder 85. The rotating plate 81 is rotatably mounted on the bottom inner wall of the lifting frame 7. Connecting rods 82 are rotatably mounted at both the front and rear ends of the top of the rotating plate 81. The two transmission blocks 83 are slidably mounted on the left and right sides inside the lifting frame 7, respectively. The bottoms of the two transmission blocks 83 are fixedly connected to the tops of the two telescopic sleeve rods 9, respectively. Hinges 84 are fixedly connected to the sides of the two transmission blocks 83 that are close to each other. The other ends of the two connecting rods 82 are hinged to the interior of the two hinges 84, respectively. The second cylinder 85 is fixedly mounted on the right end of the lifting frame 7. The output end of the second cylinder 85 passes through the right side wall of the lifting frame 7 and is fixedly connected to the right end of the right transmission block 83. The second cylinder 85 drives the right transmission block 83 to move. The right transmission block 83 drives the rotating plate 81 to rotate through the right connecting rod 82. The rotating plate 81 drives the left transmission block 83 to move through the left connecting rod 82. The two transmission blocks 83 respectively drive the two telescopic sleeve rods 9 to move closer or further apart along the slide groove 71. The telescopic sleeve rods 9 drive the pressure rollers 10 to move. The spacing of the pressure rollers 10 can be adjusted according to the creasing requirements of the corrugated cardboard. No parts need to be replaced, which reduces downtime and improves work efficiency.

[0022] The limiting component 4 includes a fixed frame 41, inside which a bidirectional screw 42 is rotatably mounted. L-shaped guide plates 43 are threaded onto both sides of the surface of the bidirectional screw 42. Limiting baffles 44 are fixedly connected to the ends of the two guide plates 43 that are close to each other. A drive motor 45 is fixedly mounted on the right end of the fixed frame 41. The output end of the drive motor 45 passes through the right side wall of the fixed frame 41 and is fixedly connected to the right end of the bidirectional screw 42. The drive motor 45 drives the bidirectional screw 42 to rotate, which in turn drives the guide plates 43 to move along the fixed frame 41. The guide plates 43 then drive the limiting baffles 44 to limit the corrugated cardboard on the conveyor belt 3, preventing the cardboard from shifting position during the creasing process, ensuring good product quality. The structure is simple, the operation is convenient, and the practicality of the device is improved.

[0023] The working principle of this utility model is as follows: Before use, the second cylinder 85 is started. Through the cooperation of the rotating plate 81 and the connecting rod 82, the transmission block 83 drives the telescopic sleeve rod 9 and the pressure roller 10 to move. The distance between the two pressure rollers 10 is adjusted according to the creasing requirements of the corrugated cardboard. The drive motor 45 is started, and the guide plate 43 is moved through the bidirectional screw 42. The guide plate 43 drives the limiting baffle 44 to limit the corrugated cardboard of different sizes to ensure accurate creasing. The biodegradable corrugated cardboard is placed on the conveyor belt 3. The first cylinder 6 is started, and the pressure roller 10 is lowered through the lifting frame 7. The pressure roller 10 is used to creasing the corrugated cardboard, and the damping spring 91 prevents excessive pressure, thus improving the practicality of the device.
