[0028] Furthermore, a grinding groove 20 is inserted inside the device housing 1, and support rods 26 are fixedly installed on both sides of the grinding groove 20. The support rods 26 are slidably connected to the device housing 1, and a reciprocating structure connected to the turntable 16 is provided on the outside of the device housing 1.

[0031] Working principle: Put the raw material into the inside of the device shell 1 from the feed port 2. When the raw material passes through the cutting blade 4, the cutting blade 4 cuts the raw material to facilitate the processing of long strips of raw material. During this process, the motor 18 is connected to the external power supply, and the motor 18 drives the turntable 16 to rotate, thereby driving the protrusion 17 to rotate around the center of the turntable 16. Since the protrusion 17 and the support plate 13 are slidably connected, the protrusion 17 can drive the support plate 13 to move up and down when rotating, and the support plate 13 drives the slider 14 to slide inside the slide groove 15.

[0032] At the same time, the support plate 13 drives the support frame 10 to move synchronously. With the cooperation of the column 11 and the No. 1 spring 12, the support plate 13 can drive the cross plate 9 to move up and down. Since the two groups of support blocks 5 are rotatably connected to the rotating shaft 6, the cross plate 9 can drive the rod 7 to move through the mounting seat 8 when lifting and lowering, thereby driving the support block 5 to move away from one end of the cutting blade 4. The cross plate 9 moves upward, pushing the two groups of support blocks 5 away from the cutting blade 4. The end of the two groups of support blocks 5 away from the cutting blade 4 is moved away from each other, and the cross plate 9 moves downward, and the two groups of support blocks 5 away from the cutting blade 4 are close to each other. When the support block 5 rotates around the rotating shaft 6, it can drive the cutting blade 4 to rotate, and the two adjacent groups of cutting blades 4 can shear the raw materials.

[0033] At the same time, the support frame 10 can drive the rolling piece 19 to move synchronously when moving. The rolling piece 19 moves inside the grinding groove 20. Since the gear 24 and the rack 25 are engaged, the rolling piece 19 can rotate when lifting and lowering. With the cooperation of the protrusion 21, the rolling piece 19 can roll the raw materials inside the grinding groove 20. The rolled raw materials fall to the bottom of the device housing 1 through the filter screen 22 and are discharged through the discharge port 3.

[0034] The outer surface of the rolling piece 19 is designed in a wave shape. When the rolling piece 19 is at the bottom of the grinding groove 20, it can drive the raw materials that are not fully ground at the bottom of the grinding groove 20 to move upward, and can also drive the raw materials inside the grinding groove 20 to circulate, so as to fully grind the raw materials.

[0035] Furthermore, when the turntable 16 rotates, it drives the fixed block 28 to move synchronously. The fixed block 28 contacts the push block 29 and drives the push block 29 to move downward. Under the action of the connecting plate 30 and the support rod 26, the grinding groove 20 can move away from the fixed block 28. When the fixed block 28 is not in contact with the push block 29, under the elastic force of the No. 2 spring 27, the grinding groove 20 can move toward the fixed block 28, so that the raw materials can be kneaded when they are crushed, thereby improving the effect of raw material grinding.
