Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to an anti-adhesion structure of a knife edge of a paper cutter. Background Art

[0002] A paper trimmer is a mechanical tool used to cut thin materials such as paper, plastic sheets, and cloth. It is widely used in printing, packaging, office, and creative handicraft industries. When using a paper trimmer to cut paper, paper scraps, glue, ink, and other substances may adhere to the blade. These sticky substances will affect the quality and efficiency of cutting. The anti-adhesive design of the paper trimmer blade is to ensure that the paper trimmer can operate efficiently, accurately, and safely. Therefore, a paper trimmer blade anti-adhesive structure is required.

[0003] The anti-sticking structure of the blade of the paper cutter currently used usually prevents the blade from sticking during cutting by setting a fixed frame, an electric telescopic rod, a scraper, a brush plate, a hydraulic cylinder, a push block, and a scraper, thereby avoiding sticky substances from sticking to the cutting blade. However, this method is inconvenient to disassemble the cutting blade when in use. When the blade becomes blunt or needs to be replaced, the inconvenient disassembly design will increase the difficulty of maintenance and extend the maintenance time. Since it is difficult to quickly replace the blade, the paper cutter will need to be shut down for a longer time when maintaining or replacing the blade, affecting production efficiency.

End, the other ends of the multiple movable plates 1 9 are rotatably connected to one end of the movable plate 2 10, the other ends of the multiple movable plates 2 10 are rotatably connected to the inside of the positioning block 8, the upper parts of the multiple movable plates 1 9 are fixedly connected to the handles 11, and the multiple insertion rods 12 are slidably connected to the inside of the mounting block 7, the upper sides of the mounting seat 4 are fixedly connected to the guide rods 14, the two guide rods 14 are slidably connected to the inner sides of the fixed frame 2, the interior of the mounting seat 4 is provided with through grooves all around, the multiple handles 11 are slidably connected to the inside of the through grooves, the two mounting blocks 7 are slidably connected to the inside of the mounting seat 4 and the mounting plate 5, and the multiple insertion rods 12 are slidably connected to the inside of the mounting seat 4.

[0024] During the operation of the paper cutter, the cylinder 3 is started, and its output end drives the mounting seat 4 to move precisely. As the mounting seat 4 moves, the guide rod 14 slides smoothly inside the fixed frame 2. At the same time, the mounting seat 4 drives the mounting plate 5 and the cutting knife 6 to move downward synchronously for efficient cutting. The cutting knife 6 moves up and down repeatedly above the workbench 1 to ensure the continuity and accuracy of the cutting operation. When disassembling the cutting knife 6, the staff only needs to easily move multiple operating handles 11. As the handle 11 rotates, the movable plate 1 9 and the movable plate 2 10 rotate accordingly, thereby prompting the insertion rod 12 to move outward. This series of actions causes the insertion rod 12 to withdraw from the inside of the mounting block 7, thereby releasing the fixed constraint on it. At this time, the mounting block 7 can be easily removed from the mounting seat 4, which provides convenience for the disassembly of the cutting knife 6.

[0025] Reference Figure 1-Figure 3 The rear part of the fixed frame 2 is fixedly connected to a fixed frame 15, one side of the fixed frame 15 is fixedly connected to a hydraulic cylinder 16, the output end of the hydraulic cylinder 16 is fixedly connected to a push plate 17, the front part of the push plate 17 is fixedly connected to a cleaning brush 20, both sides of the inside of the fixed frame 15 are fixedly connected to slide bars 18, the push plate 17 is slidably connected to the outside of the slide bar 18, the outside of the slide bar 18 is provided with a compression spring 19, one end of the two compression springs 19 is fixedly connected to the fixed frame 15, the other end of the two compression springs 19 is fixedly connected to the push plate 17, the cleaning brush 20 is slidably connected to the outside of the cutting knife 6, and the cutting knife 6 is slidably connected to the upper part of the workbench 1.

[0026] When the cutting knife 6 completes the cutting task, the hydraulic cylinder 16 is started, and the output end of the hydraulic cylinder 16 pushes the push plate 17 to move. The push plate 17 slides flexibly on the outside of the slide rod 18 and stretches or squeezes the compression spring 19 during the movement. As the push plate 17 moves, the cleaning brush 20 moves accordingly, so that it accurately reaches the outside of the cutting knife 6. During this process, an anti-sticking agent is specially added to the wool material of the cleaning brush 20, so that the cleaning brush 20 can evenly apply the anti-sticking agent to the surface of the cutting knife 6 while moving back and forth.

[0027] Working principle: During use, the air cylinder 3 is started, and the output end of the cylinder 3 pushes the mounting seat 4 to move. When the mounting seat 4 moves, it drives the guide rod 14 to slide inside the fixing frame 2. When the mounting seat 4 moves, it drives the mounting plate 5 and the cutting knife 6 to move downward synchronously. The cutting knife 6 moves up and down repeatedly on the upper part of the workbench 1 to cut. After the cutting knife 6 is used, the hydraulic cylinder 16 is started, and the output end of the hydraulic cylinder 16 pushes the push plate 17 to move. When the push plate 17 moves, it slides on the outside of the slide rod 18. When the push plate 17 slides, it stretches or squeezes the compression spring 19. When the push plate 17 moves, it drives the cleaning brush 20 to move, so that the cleaning brush 20 moves to the outside of the cutting knife 6. At the same time, anti-sticking agent is added to the wool of the cleaning brush 20, and the cleaning brush 20 moves back and forth to apply the anti-sticking agent to the outside of the cutting knife 6. , it is possible to evenly apply anti-sticking agent on the surface of the cutting knife 6, which can maintain the sharpness and cleanliness of the cutting knife 6, making the cutting process smoother and improving work efficiency. When the cutting knife 6 needs to be disassembled, the staff can pry open multiple handles 11. When the handles 11 rotate, the movable plate 1 9 and the movable plate 2 10 are driven to rotate. Under the action of the movable plate 1 9 and the movable plate 2 10, the insertion rod 12 is driven to move, so that the multiple insertion rods 12 move to both sides and move out from the inside of the mounting block 7 to release the fixation of the mounting block 7. Next, the mounting block 7 can be taken out from the inside of the mounting seat 4, and the cutting knife 6 can be disassembled, which makes it convenient to disassemble the cutting knife 6, making the replacement and maintenance of the cutting knife 6 simpler and faster, reducing downtime, and providing higher flexibility.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
