[0020] It is worth noting that in this solution, talcum powder masterbatch is used as a raw material for preparing rubber products, so rubber is used as the core to adhere talcum powder. Similarly, it can be replaced by other sticky materials.

[0021] An emission port 6 which is compatible with the extrusion hole 4 is provided on the emission conveyor disc 5. A rotating driving member for driving the emission conveyor disc 5 to rotate is provided on the granulation device body 1. The rotating driving member includes a rotating driving motor 19 arranged on the granulation device body 1. A rotating gear ring 20 is fixedly connected to the output end of the rotating driving motor 19. The emission conveyor disc 5 is fixedly connected to a vertical driving sleeve 21 which is sleeved on the conveying pipe 3. An inner gear ring 14 which is meshed with the rotating gear ring 20 is provided on the top of the vertical driving sleeve 21.

[0022] The powder mixing unit includes a powder delivery pump 7, which is a type of pump body dedicated to delivering powder materials. It is a prior art and will not be described in detail here. A plurality of powder air outlets 8 are arranged around the granulating device body 1. The inner wall of the granulating device body 1 is connected to a centralized reflux disk 9 through a connector, and a centralized reflux pipeline 10 is opened at the center of the centralized reflux disk 9. The talcum powder is circulated and transported through the powder conveying pump 7. Under the action of the reflux concentration pipeline 10 arranged at the bottom of the concentrated reflux plate 9 and the powder outlets 8 arranged around the granulator body 1, the talcum powder is ensured to move along the path in the granulator body 1 under the action of the wind vortex to achieve circulation. While the talcum powder is consumed, talcum powder can be added through the pipeline to ensure that the powder amount meets the adhesion requirement of the ball core.

[0023] The outer wall of the centralized reflux plate 9 is provided with an internal material blocking ring 11 for distinguishing masterbatches of different particle sizes, and a large material concentrating component is provided on the granulating device body 1; Further, the large material concentration component includes a concentration annular cavity 27 provided on the side wall of the granulation device body 1, a feed ring opening is provided on the inner wall of the concentration annular cavity 27, an adjustable blocking member is provided on the inner wall of the feed ring opening, the adjustable blocking member includes a mounting groove provided on the side wall of the feed ring opening, an adjustable blocking ring 28 is inserted into the inner wall of the mounting groove, and the adjustable blocking ring 28 is fastened to the inner wall of the feed ring opening by a bolt fastener 29; The advantage of adopting the above structure is that the height of the adjustable blocking ring 28 can be adjusted by the bolt fastener 29, so that the weight of the screened rubber particles can be changed when necessary to meet the control of the particle size of the talcum powder masterbatch within a certain range.

[0024] The pelletizing shaping unit rotates a rotating shaping disk 12 at the bottom of the granulation device body 1, and an inner wall of the rotating shaping disk 12 is provided with an inner concave rolling molding groove 13. Furthermore, a pellet discharge pipe 22 is provided at the bottom of the inner concave rolling molding groove 13. The reflux concentration pipeline 10 extends downward through the pellet discharge pipe 22 and is connected to the input end of the powder delivery pump 7. The output end of the powder delivery pump 7 is connected to the powder outlet 8 through multiple delivery air pipes 23.

[0025] The granulating device body 1 is provided with a high-speed rotating member for driving the rotating shaping disk 12 to rotate, and the high-speed rotating member includes a rotating motor 24 arranged on the side wall of the granulating device body 1, and a rotating gear 25 is fixedly connected to the output end of the rotating motor 24, and a concave tooth groove 26 is provided on the side wall of the rotating shaping disk 12, and the rotating gear 25 is meshed and connected with the concave tooth groove 26; Among them, the rotating shaping disk 12 will rotate under the action of the rotating motor 24, and the rotation will cause the particles with talcum powder adhered to them in the concave rotational molding groove 13 to roll continuously, so that the talcum powder and rubber on the surface are fully shaped to form talcum powder particles of uniform size, completing the talcum powder granulation process.

[0026] In the process of granulation, the talcum powder is circulated and transported by the powder conveying pump 7. Under the action of the reflux concentration pipeline 10 arranged at the bottom of the concentrated reflux disk 9 and the powder outlet 8 arranged around the granulation device body 1, the movement path of the talcum powder in the granulation device body 1 under the action of the wind vortex is ensured. At this time, the extrusion device is controlled to convey the rubber material in the hot melt state to the extrusion head 2, and the rubber material is extruded into particles from the extrusion hole 4. At this time, the high-speed rotating launch conveyor disk 5 will rotate at a high speed to cut the rubber material extruded into the launch port 6 to form particles of a predetermined size. The rotating launch conveyor disk 5 will apply a certain centrifugal force to the particles, and when the launch port 6 on the high-speed rotating launch conveyor disk 5 rotates to the high-pressure air injection port 16, the high-pressure airflow in the high-pressure air outlet cavity 15 will act on the rubber particles located in the launch port 6 to cause them to be ejected outward at a high speed. The particles in the ejection process have a certain horizontal speed. At this time, when they pass through the vortex channel formed by the talcum powder, the talcum powder will adhere to the surface of the particles, and they will move forward with the adhered talcum powder, and finally fall under the action of resistance and gravity. The talcum powder particles that meet the size requirements will fall to the outside of the internal blocking ring 11, and finally fall onto the rotating shaping disk 12. The rotating shaping disk 12 under the action of the rotating motor 24 will rotate, and the rotation will cause the particles adhered with talcum powder in the concave rotational molding groove 13 to roll continuously, so that the talcum powder on the surface is fully shaped with the rubber to form talcum powder particles of the same size, completing the granulation process of the talcum powder; Under the action of centrifugal force, smaller rubber particles will fall into the central reflux disk 9 and circulate with the talcum powder. Larger rubber particles will directly enter the central annular cavity 27 for collection under the action of centrifugal force, thereby ensuring that the manufactured talcum powder masterbatch is of uniform size.
