After the heating wire 7 is started, it will release heat and heat the feed port 104, so that the additive material will be heated when entering the feed port 104, thereby enhancing the fluidity of the additive material and improving the convenience of the granulator body 103 for processing the additive material.

[0033] Working principle: After pouring the additive raw material into the feed port 104, the device is started. The additive will enter the inside of the granulator body 103 through the feed port 104. Then the additive raw material will be heated, stirred, and extruded into granular materials by the granulator body 103. The granular materials will continue to enter the inside of the tank body 102 through the pipeline. After the device is started, the motor 105 will be driven to start. After the motor 105 is started, the shaft 112 will rotate. When the shaft 112 rotates, it will drive the fan-shaped blade 113 to rotate together. When the fan-shaped blade 113 rotates, the particles entering the tank body 102 will be squeezed and flow, and these particles will enter the inside of the sieve plate 106. At the same time, the shaft 112 rotates When the first connecting rod 107 rotates, it will drive the first connecting rod 107 to rotate together, and when the first connecting rod 107 rotates, it will also drive the fixed plate 108 to rotate together. When the fixed plate 108 rotates, it will come into contact with the particles and stir the particles, so that the particles are stirred inside the screen plate 106 and frequently collide with the screen plate 106. At this time, the particles that are not full enough will flow out from the circular holes 111. These particles will flow out from the first discharge pipe 109 and be collected, and the materials with full particles will continue to flow along the screen plate 106 to the baffle 115 under the extrusion of subsequent materials. Subsequently, the larger particles will flow out from the gap between the screen plate 106 and the baffle 115 and reach the second discharge pipe 110. Finally, the staff can The larger particles are collected at the second discharge pipe 110; when the fixed plate 108 rotates, the second magnet 25 is driven to rotate together, and the distance between the second magnet 25 and the first magnet 23 is changed when the second magnet 25 rotates. When the second magnet 25 and the first magnet 23 are close to each other, the first magnet 23 is attracted by the second magnet 25, and the first magnet 23 transmits the magnetic force to the top plate 22 so that the top plate 22 moves and approaches the screening plate 106, and the top plate 22 transmits the magnetic force to the first spring 2 so that the first spring 2 is in a stretched state. When the top plate 22 moves, the first bristles 24 are driven to approach the screening plate 106 together, and when the first bristles 24 move, they enter the inside of the circular hole 111 and press the circular hole 111 1 is dredged to reduce the particles remaining in the circular hole 111, so as to ensure the particle screening function of the screening plate 106; when the top plate 22 moves, it will drive the slide bar 3 to move together, and when the slide bar 3 moves, it will also drive the rubber pad 32 to move together. When the rubber pad 32 moves, it will contact the surface of the screening plate 106 before the slide bar 3. Because the rubber pad 32 is a flexible material, when the rubber pad 32 contacts the screening plate 106, it will absorb the impact generated when the slide bar 3 and the screening plate 106 contact, thereby reducing the impact on the screening plate 106. After the slide bar 3 and the screening plate 106 contact, they will slide along the top plate 22 under the action of pressure, and when the slide bar 3 slides, the second spring 33 will be in a stretched state;When the particles enter the tank 102 from the granulator body 103 through the pipeline, the particles will reach the surface of the buffer plate 4. At this time, the speed of the particles will decrease after contacting the buffer plate 4. Then the particles will flow along the surface of the buffer plate 4 and flow out from the edge of the buffer plate 4. Then the particles will reach the surface of the roller 44 and flow along both sides of the roller 44, so that the particles are diverted by the roller 44, increasing the contact area between the particles and the fan-shaped blade 113; when the particles flow along the surface of the roller 44, the particles will come into contact with the second brush 5. When the second brush 5 comes into contact with the particles, it will clean the surface of the particles, reduce impurities on the surface of the particles, and improve the smoothness of the surface of the particles. ; Smaller particles will enter the interior of the collection box 6 through the first discharge pipe 109 and then flow along the surface of the partition 62, while larger particles will enter the interior of the collection box 6 through the second discharge pipe 110. Because the partition 62 is inclined, the particles can slide along the partition 62 more quickly, reducing the accumulation of particles at the first discharge pipe 109; After the device is started, the heating wire 7 will also be started. After the heating wire 7 is started, it will release heat and heat the feed port 104, so that the additive material will be heated when entering the feed port 104, enhancing the fluidity of the additive material and improving the convenience of the granulator body 103 for processing the additive material. ;
