Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper cutting, in particular to a cutting device for kraft paper processing. Background Technique

[0002] Kraft paper usually maintains its natural yellowish-brown color and has high strength. It is widely applicable to various packaging supplies, such as paper bags, kraft paper for handbags, color boxes, gift boxes made of kraft paper, printed kraft paper. The printing of kraft paper can adopt flexographic printing, gravure printing, offset printing, and screen printing processes. Kraft paper is one of many types of paper, and during the production process, it needs to be wound and cut, and a cutting device is mostly used for cutting. After the existing kraft paper cutting equipment finishes cutting the kraft paper, workers need to stand in front of the cutting equipment to pick it up. However, the moving kraft paper may scratch the hands of the workers. Moreover, after the traditional kraft paper is conveyed over a long distance, the cut kraft paper may be mixed with waste materials, resulting in the need for workers to sort it out later.

[0003] After retrieval, in the prior art, the publication number: CN216853921U discloses a kraft paper cutting device for clothing pattern design, belonging to the technical field of kraft paper processing, which solves the problems that the existing kraft paper cutting device is not convenient for conveying and limiting, and the cutting width cannot be adjusted. Its technical key points are: including a bottom plate, on which a conveying roller and a receiving roller for conveying kraft paper are respectively arranged. A guiding and conveying mechanism is arranged inside the first support frame, and a cutting mechanism is arranged inside the second support frame. The motor operates to wind the cut kraft paper, and drives the first driving roller and the second driving roller to rotate towards each other to convey the kraft paper. The first cutting adjustment group and the second cutting adjustment group realize the adjustment of the positions of the cutting knife and the cutting seam. The elastic conveying group can conduct guiding and conveying according to kraft paper of different thicknesses, and the lifting adjustment group can perform lifting adjustment for cutting according to kraft paper of different thicknesses, having the advantages of being convenient for conveying and limiting and adjustable cutting width.

[0004] When the above patent is used, workers need to stand in front of the equipment to pick up the materials, which may cause the hands of the workers to be scratched by the moving kraft paper. Therefore, we need to propose a cutting device for kraft paper processing. Content of the Utility Model

A guide wheel 17 and a cutting knife 19 are arranged on the upper surface of the operating table 1. A rotating column 9 is rotatably arranged on the upper surface of the operating table 1. A collecting box 11 is fixedly connected to the outer arc surface of the rotating column 9, and the collecting box 11 is located below the vacuum suction cup 12. A contact column 13 is symmetrically arranged on the outer arc surface of the rotating column 9 and the collecting box 11;

[0026] A moving component for driving the vacuum suction cup 12 to move up and down is arranged on the upper surface of the operating table 1;

[0027] A rotating component for driving the collecting box 11 to rotate is arranged on the side of the vacuum suction cup 12; after the vacuum suction cup 12 moves down to adsorb the kraft paper on the upper surface of the operating table 1, the moving component drives the vacuum suction cup 12 to rise. At this time, the rotating column 9 drives the collecting box 11 to rotate to the lower part of the vacuum suction cup 12 under the action of the spring 10. The vacuum suction cup 12 then puts the kraft paper into the collecting box 11. Then, when the moving component drives the vacuum suction cup 12 to move down to adsorb another group of kraft paper, the guide plate 8 moves downwards following the vacuum suction cup 12. The guide plate 8 drives the rotating column 9 to rotate by squeezing the contact column 13, thereby driving the collecting box 11 away from the vacuum suction cup 12, facilitating the staff to take out the kraft paper inside the collecting box 11, thus avoiding the staff from being scratched by the moving kraft paper and avoiding the mixing of the kraft paper with waste materials after long-distance transportation.

[0028] Preferably, the moving component includes a mounting frame 2, a servo motor 5, a connecting rod 6, a moving block 15 and a lead screw 16. The mounting frame 2 is fixedly installed on the upper surface of the operating table 1. The servo motor 5 is bolted to the top of the mounting frame 2. The lead screw 16 is rotatably arranged inside the mounting frame 2, and the lead screw 16 is key-connected to the output end of the servo motor 5. The moving block 15 is threadedly sleeved on the outer arc surface of the lead screw 16. The servo motor 5 is supported by the mounting frame 2. Starting the servo motor 5 drives the lead screw 16 to rotate. Through the cooperation of the moving block 15 and the lead screw 16, the technical effect of driving the moving block 15 to move up and down along the lead screw 16 is achieved, and the problem of driving the vacuum suction cup 12 to move up and down to adsorb the kraft paper is solved.

[0029] It should be noted that the lead screw 16 is arranged as a convex block, and the lead screw 16 is slidably arranged inside the mounting frame 2. The connecting rod 6 is fixedly installed at one end of the moving block 15 close to the vacuum chuck 12, and a connecting plate 14 is fixedly arranged on the side surface of the connecting rod 6. The vacuum chuck 12 is arranged on the lower surface of the connecting plate 14. When the moving block 15 moves up and down, it drives the connecting rod 6 to move up and down. The connecting rod 6 drives the vacuum chuck 12 to move up and down through the connecting plate 14 to adsorb the cut kraft paper on the upper surface of the operating table 1. And through the cooperation of the convex moving block 15 and the mounting frame 2, the technical effect of the moving block 15 sliding up and down along the inside of the mounting frame 2 is achieved, and the technical problem that the rotation of the lead screw 16 drives the moving block 15 to rotate is solved.

[0030] Furthermore, the rotating assembly includes an extension plate 7 and a guide plate 8. The extension plate 7 is fixedly arranged on the side of the connecting plate 14 away from the mounting frame 2, and the guide plate 8 is fixedly installed on the side of the extension plate 7 away from the mounting frame 2. And the guide plate 8 is arranged as a special-shaped plate. When the connecting plate 14 moves, it drives the guide plate 8 to move up and down through the extension plate 7. And a groove corresponding to the rotating column 9 is opened on the side surface of the extension plate 7, so as to avoid rubbing between the extension plate 7 and the rotating column 9 when the extension plate 7 moves up and down. The guide plate 8 is arranged as the special-shaped plate shown in the figure, so that through the cooperation of the guide plate 8 and the contact column 13, the technical effect that the guide plate 8 drives the rotating column 9 to rotate when moving up and down by squeezing the contact column 13 is achieved, and the technical problem that the vacuum chuck 12 rubs against the collection box 11 when moving down is solved.

[0031] Even further, a spring 10 is fixedly sleeved on the outer arc surface of the rotating column 9, and the bottom end of the spring 10 is fixedly connected to the upper surface of the operating table 1. The spring 10 is arranged as a spring with a small top end and a large bottom end. The top end of the spring 10 is fixedly connected to the rotating column 9, and the bottom end of the spring 10 is fixedly connected to the operating table 1. And when the collection box 11 is located below the vacuum chuck 12, the spring 10 is in a normal state. When the rotating column 9 drives the collection box 11 to move away from the vacuum chuck 12, the spring 10 will rotate following the rotating column 9. And when the guide plate 8 rises away from the contact column 13, through the cooperation of the rotating column 9 and the spring 10, the technical effect of driving the rotating column 9 to rotate back to its original position by the spring 10 is achieved, and the technical problem that the collection box 11 cannot return below the vacuum chuck 12 is solved.

A hydraulic push rod 4 is arranged inside the support frame 3, and a cutting knife 19 is fixedly connected to the working end of the hydraulic push rod 4. Two groups of limiting plates 18 are symmetrically arranged on the upper surface of the operating table 1 and inside the support frame 3. By arranging the limiting plates 18 to limit the kraft paper, through the cooperation of the hydraulic push rod 4 and the cutting knife 19, the technical effect of the hydraulic push rod 4 driving the cutting knife 19 to move up and down to cut the kraft paper is achieved, and the arrangement of the two groups of limiting plates 18 solves the technical problem that the kraft paper cannot move below the cutting knife 19.

[0033] In addition, the guide wheel 17 is rotatably arranged on the upper surface of the operating table 1, and the guide wheel 17 is located between the mounting frame 2 and the support frame 3. By arranging the guide wheel 17, the technical effect of driving the cut kraft paper to move below the vacuum suction cup 12 is achieved, and the technical problem that the staff needs to manually move the kraft paper is solved.
