[0002] Slitting blades, also known as cutting blades, are tools used to cut and separate materials. They are usually made of high-hardness and wear-resistant materials, such as high-speed steel, tungsten carbide, and ceramics. Slitting blades are widely used in many industries and fields, including paper processing, plastic processing, rubber processing, and metal processing. Their main function is to cut materials to divide large pieces of material into the required size and shape for further processing or use.

[0003] Currently, the combination cutting blades on the market have a relatively simple way of cutting objects. It is difficult to adjust the spacing between adjacent blades at equal intervals for cutting objects, resulting in low cutting efficiency. Furthermore, the blades are prone to chipping and breaking during the cutting process. The installation and removal of blades on the market are also quite troublesome, leading to high maintenance costs.

[0004] In response to the technical problems of adjusting the spacing between adjacent blades at equal intervals and the inconvenience of installing and disassembling blades, this application proposes a combined slitting blade. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3This utility model provides an embodiment of a combined slitting blade, comprising a base plate 1 serving as a support, with fixed plates 7 fixedly connected to the left and right sides of the bottom end of the base plate 1. Four sliding plates 8 are provided at the top of the fixed plates 7, with the bottom end of the foremost sliding plate 8 fixedly connected to the top of the fixed plate 7, and the bottom ends of the remaining sliding plates 8 slidably connected to the bottom of the fixed plate 7. A first fixed rod 10 is fixedly connected to the inner wall of the sliding plate 8, with a first upper connecting rod 11 slidably connected to the upper side of the first fixed rod 10, and a first lower connecting rod 12 slidably connected to the lower side of the first fixed rod 10. The first upper connecting rod 11 and the first lower connecting rod 12 are alternately connected. Four sliders 9 are provided at the top of each of the four sliding plates 8, with the bottom ends of the four rightmost sliders 9 fixedly connected to the top of the sliding plate 8, and the bottom ends of the remaining sliders 9 slidably connected to the top of the sliding plate 8. (Referring to...) Figure 4 A second fixed rod 14 is fixedly connected to the inner wall of slider 9. A second upper connecting rod 15 is slidably connected to the upper side of the second fixed rod 14. A second lower connecting rod 16 is slidably connected to the lower side of the second fixed rod 14. The second upper connecting rod 15 and the second lower connecting rod 16 are alternately connected. A first motor 2 is fixedly connected to the rear side of the top of the base plate 1. A first lead screw 5 is fixedly connected to the drive end of the first motor 2. The front end of the first lead screw 5 is slidably connected to the bottom end of the base plate 1. A push block 6 is threadedly connected to the outer wall of the first lead screw 5. The right end of the push block 6 is fixedly connected to the left end of the last side slide plate 8. A second motor 3 is fixedly connected to the front side of the bottom end of the base plate 1. A second lead screw 4 is fixedly connected to the drive end of the second motor 3. The right end of the second lead screw 4 is slidably connected to the bottom end of the base plate 1. A connecting plate 13 is threadedly connected to the outer wall of the second lead screw 4. The right end of the connecting plate 13 is fixedly connected to the left end of the leftmost slider 9.

[0030] Specifically, the first motor 2 is started, driving the first lead screw 5 to rotate, causing the push block 6 to slide. The push block 6 drives the foremost slide plate 8 to slide on the fixed plate 7. The slide plate 8 drives the first upper connecting rod 11 and the first lower connecting rod 12 to rotate on the first fixed rod 10. Since the first upper connecting rod 11 and the first lower connecting rod 12 are interleaved, the slide plates 8 move at equal intervals. The second motor 3 is started, driving the second lead screw 4 to rotate, causing the connecting plate 13 to slide. The connecting plate 13 drives the four leftmost sliders 9 to move. The sliders 9 drive the second upper connecting rod 15 and the second lower connecting rod 16 to rotate on the second fixed rod 14. Since the second upper connecting rod 15 and the second lower connecting rod 16 are interleaved, the sliders 9 move at equal distances. The above operations enable the cutter holder 18 to achieve equal distance adjustment in two directions on the horizontal plane, meeting the needs of cutting more objects, improving cutting quality, and improving cutting efficiency. The base plate 1 is used to support and protect the device, and the top of the base plate 1 can also hold the objects to be cut.

[0031] Reference Figures 5-7A rectangular shell 19 serves as a fixing element, with its bottom end fixedly connected to the top of the slider 9. A support rod 21 is fixedly connected to the bottom of the inner wall of the rectangular shell 19, and a first conical limiting body 20 is fixedly connected to the top of the support rod 21. A second conical limiting body 22 is slidably connected to the lower outer wall of the support rod 21. A limiting shell 17 is inserted into the inner wall of the rectangular shell 19, wherein reference... Figure 8 A rectangular plate 26 is slidably connected to the inner wall of the left end of the limiting shell 17. A connecting rod 24 is fixedly connected to the right end of the rectangular plate 26. The outer wall of the connecting rod 24 is slidably connected to the inner wall of the limiting shell 17. The left end of the limiting block 23 is fixedly connected to the right end of the connecting rod 24. The outer wall of the limiting block 23 is slidably connected to the inner wall of the left end of the limiting shell 17. A spring 25 is fixedly connected to the outer wall of the connecting rod 24 at the left end of the inner wall of the limiting shell 17. The right end of the spring 25 is fixedly connected to the left end of the limiting block 23. A blade holder 18 is fixedly connected to the top of the limiting shell 17 for cutting objects.

[0032] Specifically, when installing the tool holder 18, the limiting shell 17 is inserted into the inner wall of the rectangular shell 19. When the limiting block 23 touches the first conical limiting body 20, it gradually moves the second lower connecting rod 16 along with the connecting rod 24 and compresses the spring 25, eventually locking between the first conical limiting body 20 and the support rod 21. When replacing the tool holder 18, the limiting shell 17 is pressed down, and the limiting block 23 retracts when it touches the second conical limiting body 22. Then, the second conical limiting body 22 is lifted and the second conical limiting body 22 is... Sliding on the support rod 21, after the second conical limiting body 22 comes into close contact with the first conical limiting body 20, the limiting block 23 can retract, thereby removing the limiting shell 17 from the rectangular shell 19. Through the cooperation between the limiting block 23 and the two cones, it is convenient to install and disassemble the cutting blade, reduce the debugging time of the workers, improve the flexibility of production, and improve the practicality of the device. The limiting block 23 cuts half of the side, which is convenient to move on the first conical limiting body 20 and the second conical limiting body 22.

[0033] Working principle: Starting the first motor 2 rotates the first lead screw 5, causing the push block 6 to slide. The push block 6 drives the foremost slide plate 8 to slide on the fixed plate 7. The slide plate 8 drives the first upper connecting rod 11 and the first lower connecting rod 12 to rotate on the first fixed rod 10. Because the first upper connecting rod 11 and the first lower connecting rod 12 are interleaved, the slide plates 8 move at equal intervals. Starting the second motor 3 rotates the second lead screw 4, causing the connecting plate 13 to slide. The connecting plate 13 drives the four leftmost sliders 9 to move. The sliders 9 drive the second upper connecting rod 15 and the second lower connecting rod 16 to rotate on the second fixed rod 14. Because the second upper connecting rod 15 and the second lower connecting rod 16 are interleaved, the sliders 9 move at equal distances. This operation allows the cutter holder 18 to achieve equal-distance spacing adjustment in two directions on the horizontal plane, meeting the needs of cutting more objects, improving cutting quality, and enhancing cutting efficiency. In terms of work efficiency, when installing the cutter holder 18, the limiting shell 17 is inserted into the inner wall of the rectangular shell 19. When the limiting block 23 touches the first conical limiting body 20, it gradually moves the second lower connecting rod 16 along with the connecting rod 24 and compresses the spring 25, eventually locking between the first conical limiting body 20 and the support rod 21. When changing the cutter holder 18, the limiting shell 17 is pressed down. When the limiting block 23 touches the second conical limiting body 22, it retracts. Then, the second conical limiting body 22 is lifted and slids on the support rod 21. After the second conical limiting body 22 is in close contact with the first conical limiting body 20, the limiting block 23 can retract, thereby removing the limiting shell 17 from the rectangular shell 19. Through the cooperation between the limiting block 23 and the two cones, it is convenient to install and disassemble the slitting blade, reducing the debugging time of the workers, improving the flexibility of production, and improving the practicality of the device.
