[0002] During the shredding process, the blade is one of the key components of the shredder, responsible for cutting and crushing the material. Since the blade is in direct contact with the material during the shredding process, the blade is easily worn, blunted or damaged, and requires regular maintenance and replacement.

[0003] Currently, most shredder blades on the market are fixed to the cutter shaft by screws, and the disassembly and replacement process is relatively cumbersome. The blade fixing screws are often located in difficult-to-reach positions, and special tools are required for disassembly, which takes operators a long time to complete. This not only increases the difficulty of maintenance and replacement and prolongs equipment downtime, but also makes the blade difficult to disassemble. Operators may resort to unsafe methods to forcibly disassemble it, such as using a hammer or a crowbar to pry, etc. These behaviors increase the risk of work-related injuries. Therefore, a quick-detachable shredder blade is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] See also Figure 1-3 The utility model provides a technical solution: a quick-detachable shredder blade, comprising a knife roller 1, an upper blade 2 and a lower blade 3. The upper blade 2 and the lower blade 3 are movably mounted on the outer surface of the lower blade 3. A through slot 4 is provided at the middle end of the inner part of the knife roller 1. A linkage column 5 is movably inserted inside the through slot 4. A limiting slot 7 is provided inside the upper blade 2 and the lower blade 3. A movable slot 6 is annularly distributed inside the knife roller 1. A positioning column 8 is movably inserted inside the movable slot 6 and the limiting slot 7. One end of the positioning column 8 is movably connected to the linkage column 5, and one end of the linkage column 5 is a circular structure.

[0018] The outer surface of the knife roller 1 is symmetrically provided with a mounting seat 11, and slots 12 are opened at the left and right ends of the mounting seat 11. A fixed magnet 13 is installed at the middle end of the mounting seat 11. The mounting seat 11 can be an installation guide. The mounting seat 11 is movably connected with the movable magnet 14 through the internal slot 12, and can position and install the upper blade 2 and the lower blade 3 so that the inner walls of the upper blade 2 and the lower blade 3 are in contact with the outer wall of the knife roller 1. At the same time, the position of the limiting groove 7 of the upper blade 2 and the lower blade 3 corresponds to the position of the movable groove 6 of the knife roller 1, thereby increasing the convenience of installation.

[0019] One end of the upper blade 2 and the lower blade 3 is respectively provided with a movable magnet 14, one end of the movable magnet 14 is movably plugged into the slot 12 and is magnetically connected to the fixed magnet 13. The upper blade 2 and the lower blade 3 are magnetically connected to the fixed magnet 13 through the movable magnet 14 plugged into the knife slot 12, so that the upper blade 2 and the lower blade 3 are magnetically adsorbed and fixed to the knife roller 1 during the installation process, avoiding the situation where the two ends will fall off if they are not supported and fixed during the installation process, thereby reducing the difficulty of installation.

[0020] A fixed plate 9 is slidably connected to the inside of the movable groove 6. The fixed plate 9 is arranged on the outer surface of one end of the positioning column 8. A spring 10 is arranged between the fixed plate 9 and the movable groove 6. The positioning column 8 cooperates with the fixed plate 9 and the spring 10 to facilitate resetting. The linkage fixation can be performed without tools, thereby further increasing the installation efficiency.

[0021] A fixing groove 15 is provided at the front end of the knife roller 1. The center point of the fixing groove 15 and the center point of the linkage column 5 are located on the same horizontal line. The fixing groove 15 corresponds to the other end of the linkage column 5, which is convenient for positioning and installation.

[0022] A fixing plate 16 is provided at one end of the linkage column 5, and the fixing plate 16 and the fixing groove 15 are threadedly connected with a fixing bolt 17. The fixing plate 16 and the fixing groove 15 are connected by the fixing bolt 17 to fix the position of the linkage column 5, thereby ensuring that one end of the positioning column 8 will not extend into the through groove 4, thereby improving the stability of the structure.

[0023] Working principle: the upper blade 2 and the lower blade 3 correspond to the positions of the knife roller 1 respectively, and the movable magnets 14 of the upper blade 2 and the lower blade 3 are connected to the slot 12 of the mounting seat 11 in a horizontal plug-in manner, and are magnetically connected and fixed with the fixed magnet 13 inside the slot 12. Then, one end of the linkage column 5 is inserted into the through slot 4 of the knife roller 1. During the pushing process of one end of the linkage column 5, the positioning column 8 will follow the circular part of the front end of the linkage column 5 and slide to the surface of the linkage column 5. At the same time, the positioning column 8 is inserted into the limiting groove 7 of the upper blade 2 and the lower blade 3, which can limit and fix the upper blade 2 and the lower blade 3, increase the lateral force area of ​​the blade, and finally the fixed plate 16 at one end of the linkage column 5 fits into the fixing groove 15 and is fixed with the fixing bolt 17. When disassembly is required, just pull out the linkage column 5, and the positioning column 8 will be reset under the action of the spring 10.
