[0017] Such as Figure 1-2As shown in the figure, a screw extrusion granulation device includes a housing 2, a motor 1, a screw blade 3, an extrusion plate 5, a plurality of fixing plates 6 and a plurality of blades 10. The housing 2 is a cylindrical housing 2 with one end open. The extrusion plate 5 is plugged and arranged at the opening position of the housing 2, and a plurality of extrusion holes 18 are arranged in a circular matrix on the extrusion plate 5. The motor 1 is arranged at the center position of the other end of the housing 2, and the output end of the motor 1 is connected with a rotating shaft 4. The rotating shaft 4 penetrates through the center position of the housing 2 and penetrates out of the extrusion plate 5. The rotating shaft 4 is rotatably connected with the housing 2 and the extrusion plate 5 through bearings 15. The screw blade 3 is arranged on the rotating shaft 4. On one side of the top of the side surface of the housing 2 close to the motor 1, there is a feed inlet 16. On one end of the rotating shaft 4 that penetrates out of the extrusion plate 5, there is an installation seat 11. A plurality of blades 10 are evenly arranged on the side surface of the installation seat 11, and the blades 10 are close to the side wall of the extrusion plate 5. A plurality of fixing plates 6 are evenly arranged on the side surface of the open end of the housing 2. The fixing plates 6 and the extrusion holes 18 are designed to be staggered in the radial direction of the housing 2. Through holes 13 are arranged in the radial direction of the end face of the housing 2 on the fixing plates 6. A blocking rod 9 is movably arranged in each through hole 13. A clamping plate 7 is arranged at the outer end of the blocking rod 9. A spring 8 is arranged between the clamping plate 7 and the fixing plate 6. The other end of the blocking rod 9 extends to a position close to the installation seat 11. The blocking rod 9 is arranged close to the outer surface of the blade 10. A plurality of vibration blocks 17 are evenly arranged on the side surface of the installation seat 11. The side of the vibration block 17 corresponding to contacting the blocking rod 9 is arranged as an inclined surface. A limiting plate 19 is arranged at the position of the end face of the housing 2 corresponding to the blocking rod 9. A limiting hole 20 for limiting the blocking rod 9 is arranged on the limiting plate 19. A sealing gasket 12 is arranged at the positions of the rotating shaft 4, the extrusion plate 5 and the housing 2. The fixing plate 6 and the housing 2 are connected by screws 14.

[0018] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] According to the attached drawings of the specification Figure 1-2It can be seen that when the utility model works, feeding is carried out through the feeding port 16 on the housing 2. The motor 1 works to drive the rotating shaft 4 and the spiral blade 3 to rotate. In cooperation with the extrusion holes 18 on the extrusion plate 5, extrusion operation is carried out. The rotation of the rotating shaft 4 drives the mounting seat 11 and the blade 10 to rotate, cutting the extruded material to form particles. After the blade 10 cuts, particles may adhere to the outer cutting surface. Since a plurality of fixing plates 6 are evenly arranged on the side surface of the open end of the housing 2, the fixing plate 6 and the extrusion holes 18 are designed to be offset in the radial direction of the housing 2. Through holes 13 are formed in the fixing plate 6 along the radial direction of the end surface of the housing 2. A blocking rod 9 is movably arranged in each through hole 13. The blocking rod 9 extends to a position close to the mounting seat 11 and is arranged close to the outer surface of the blade 10. Therefore, the rotation of the blade 10 can drive the adhered particles to rotate, which are blocked and intercepted by the blocking rod 9, cleaning the blade 10. Also, since a clamping plate 7 is arranged at the outer end of the blocking rod 9, a spring 8 is arranged between the clamping plate 7 and the fixing plate 6. A plurality of vibration blocks 17 are evenly arranged on the side surface of the mounting seat 11. The side of the vibration block 17 corresponding to contacting the blocking rod 9 is set as an inclined surface. As Figure 2 shown, the mounting seat 11, the blade 10 and the vibration block 17 rotate counterclockwise. The blocking rod 9 is pushed up by the inclined surface side of the vibration block 17, that is, the blocking rod 9 moves along its axial direction, and the spring 8 is stretched. When the blocking rod 9 suddenly breaks away from the vibration block 17, the spring 8 instantaneously resets. The function of the spring 8 causes the blocking rod 9 to vibrate, so that the particles blocked by it are shaken off, avoiding particle adhesion. Compared with the prior art, the adhered particles on the blade 10 are blocked by the blocking rod 9, and the blocking rod 9 is axially pushed by the vibration block 17, and the spring 8 is cooperated to make the blocking rod 9 vibrate, completely shaking off the particles that may adhere to the blocking rod 9, reducing the generation of particle adhesion and improving the production quality.

[0020] Wherein, a limiting plate 19 is arranged at the position of the end surface of the housing 2 corresponding to the blocking rod 9. A limiting hole 20 for limiting the blocking rod 9 is arranged on the limiting plate 19. The blocking rod 9 penetrates through the through hole 13 of the fixing plate 6 and the limiting hole 20 of the limiting plate 19 at the same time, ensuring that the blocking rod vibrates in the axial direction, avoiding non-axial deviation and wear, and thus improving the service life.

[0021] Wherein, a sealing gasket 12 is arranged at the positions of the rotating shaft 4, the extrusion plate 5 and the housing 2 to protect the bearing 15.

[0022] Wherein, the fixing plate 6 is connected to the housing 2 by screws 14, which can be disassembled, facilitating repair and maintenance.

[0023] In addition, the connection between the mounting seat 11 and the rotating shaft 4 can also be fixed by the screw 14 method, which can be disassembled, facilitating repair and maintenance.

[0024] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
