[0002] In the process of using a pulverizer, there are situations where it is necessary to pulverize materials of different materials. However, given the differences in the properties of different materials, it is difficult to meet the demand for efficient pulverization using the same type of blade with a fixed angle.
[0003] The main reason is that pulverizers have a wide range of applications and deal with materials with different characteristics, such as hardness, toughness, and fiber content. When using traditional pulverizer blades, the pulverizing and cutting angles are fixed. For materials with high hardness, such as wood, fixed-angle blades may not be able to cut effectively, resulting in low cutting efficiency and even causing excessive wear or damage to the blades. For materials with high toughness, such as plastics, fixed angles may not be able to cut them well, and the material may easily become entangled in the blades, affecting the pulverizing effect and the normal operation of the equipment. Therefore, it is difficult to meet the demand for high-efficiency pulverization using the same type of fixed-angle blades. Utility Model Content

[0024] 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.
[0025] Please see Figure 1-4An adjustable-angle pulverizer blade includes a blade holder 1, a main shaft 2, a blade body 3, and a positioning plate 4. The blade holder 1 is penetrated by the main shaft 2, one end of which is connected to a motor that drives the main shaft 2. The other end of the main shaft 2 is movably mounted on the pulverizer body. The blade body 3 is located on the outer side of the blade holder 1, with an angle difference between adjacent blade bodies 3. The blade body 3 always surrounds the outer side of the blade holder 1. When there is an angle difference between adjacent blade bodies 3, as the blade holder 1 rotates continuously, the material is continuously pulverized by the blade body 3 with the angle deviation, so that the material is subjected to multi-angle cutting forces during the pulverization process, further optimizing the pulverization effect. The positioning plate 4 is located on the outer side of the blade body 3, and the positioning plate 4 is equipped with... Two positioning rods 41 are threaded onto the blade body 3, helping to fix the positioning plate 4 onto the blade body 3. The positioning plate 4 protects the top of the blade body 3 and the top of the screw 32, preventing the blade body 3 from being subjected to external impact or wear during high-speed rotation, and enhancing the stability of the overall structure. The blade body 3 has four blades arranged in an array on the outside of the blade holder 1, ensuring uniform force on the material during crushing and improving crushing efficiency. A rotating plate 31 is fixedly connected to the side of the blade body 3 closest to the blade holder 1. The rotating plate 31 is inserted into the plate groove 22 on the outside of the blade holder 1. In the side slot 22, the rotating plate 31 is penetrated by the shaft and rotates around the shaft within the slot 22. The blade body 3 is penetrated by the screw 32, which is threadedly connected to the outer sleeve 33. The bottom of the positioning slot 21 has three threaded grooves at different angles. All the threaded grooves in the positioning slot 21 are threadedly connected to the screw 32. When the screw 32 is inserted into the three threaded grooves at different angles, the direction of the blade body 3 fixedly connected to the screw 32 can be adjusted. The screw 32 selects the appropriate angle of the threaded groove according to the rotation direction to cooperate, so that the blade body 3 and the tool holder 1 form three angles of cooperation, thereby adjusting the cutting angle of the blade body 3. The tool holder 1 will rotate with the spindle 2, driving the blade body 3 to rotate. The rotating body 3 drives the main shaft 2 to rotate via a motor, which in turn drives the cutter holder 1 and the blade body 3 to perform a crushing operation. The cutter head at the front end of the blade body 3 crushes the material. When the angle of the blade body 3 needs to be adjusted, the rotating sleeve 33 is used. Since the screw 32 and the sleeve 33 are threadedly connected, the screw 32 will move linearly relative to the sleeve 33 during the rotation of the sleeve 33. The top of the sleeve 33 is located inside the blade body 3, and the bottom of the sleeve 33 extends out of the bottom of the blade body 3. Movable ends 34 are fixedly connected to both sides of the sleeve 33, and the movable ends 34 are movably inserted into the blade body 3. The movable ends 34 are located in the upper middle position on the sleeve 33. When the movable ends 34 are inserted into the blade body 3...The top of the sleeve 33 can be fully inserted into the interior of the blade body 3. The screw 32 is inserted into the positioning groove 21 on the outside of the tool holder 1. The bottom of the positioning groove 21 has threaded grooves at different angles. The screw 32 moves within the positioning groove 21 and engages with the threaded grooves at appropriate angles. As the screw 32 rotates and descends, it is installed into the threaded groove inside the positioning groove 21, causing the blade body 3 to rotate around the axis of the rotating plate 31, thereby adjusting the cutting angle of the blade body 3.
[0026] Working Principle: This utility model discloses a shredder blade with adjustable cutting angle. During use, the motor starts and transmits power to the main shaft 2 via a transmission device, causing the main shaft 2 to rotate. The blade holder 1 rotates with the main shaft 2, serving as the mounting base for the blade body 3. The rotation of the blade holder 1 further drives the blade body 3 to rotate. During rotation, the cutting head at the front end of the blade body 3 shreds the material. Since there is an angle difference between adjacent blade bodies 3, the material is subjected to cutting forces from multiple angles during shredding. When the angle of the blade body 3 needs to be adjusted, the operator rotates the sleeve 33. Because the screw 32 and the sleeve 33 are threadedly connected, the screw 32 moves linearly relative to the sleeve 33 during rotation. Simultaneously, the bottom of the positioning groove 21 has threaded grooves at different angles, allowing the screw 32 to move within the positioning groove 21 and engage with the appropriate threaded groove. As the screw 32 rotates and descends, it enters the threaded groove inside the positioning slot 21, causing the blade body 3 to rotate around the shaft of the rotating plate 31. This allows for adjustment of the cutting angle of the blade body 3. During the adjustment process, the shaft passes through the rotating plate 31, and both ends of the shaft are supported in the plate groove 22 of the tool holder 1, ensuring that the blade body 3 remains stable during rotation and angle adjustment.
