10. A granulation device for plastic masterbatch processing and a process thereof according to any one of claims 1-9, characterized in that: the granulation process comprises the following steps;

S1: When granulating plastics, the screw extrusion melting machine (8) works to melt the raw materials and transports them to the extrusion box (12). At this time, the extrusion cylinder (21) works to drive the extrusion boss ( 22) In the extrusion box (12), the sliding rod (32) moves downward on the installation frame 1, and the raw material in the molten state is squeezed downward and a number of discharge holes on the bottom of the extrusion box (12) (13) The raw material strip is formed on the top and discharged downward;

S2: When the raw material is extruded, some discharge holes (13) on the extrusion box (12) may cause residues to block the discharge holes (13). At this time, the extrusion cylinder (21) works Move the extrusion cylinder (21) down to the lowest point in the extrusion box (12), and the rotating motor (37) works to drive the rotating cam (36) so that the rotating cam (36) contacts the rotating wheel (34), so that The rotating wheel (34) moves downwards on the mounting plate (31) through the sliding rod (32), and the downward movement of the sliding rod (32) drives the dredging plate (30) to move downwards, and some dredging plates under the dredging plate (30) are moved downwards. The bar (38) moves downward from several scraping holes (39) to the discharge hole (13), dredging the remaining raw materials in the discharge hole (13), preventing the discharge hole (13) from being blocked and affecting the subsequent use;

S3: When the raw material strip is extruded downward, the two cutting horizontal sliding tables (42) work at the same time to drive the position of the cutting blade (41) to move left and right at the bottom of the extrusion box (12), cutting the raw material strip so that the raw material The strips form plastic particles and fall on the dust removal screen (53) on the receiving seat (51). When the cutting blade (41) moves left and right, the bottom of the extrusion box (12) can also be positioned at the discharge hole (13). Scrape off the remaining material on the surface to prevent the residual material from being extruded into raw material strips, which will affect the molding effect;

S4: After the plastic granules are cut off and dropped onto the ash removal screen (53), the rotating motor (62) works to drive the turning vane wheel (61) to rotate on the sliding plate (63), and the turning vane wheel (61) rotates on the dedusting screen (53). Rotating on the ash screen (53) can drive the falling particles to flip, and when the different positions on the ash removal screen (53) are turned over, the sliding motor (65) works to drive the sliding screw (66) in the sliding frame. (67) is rotated, thereby driving the sliding plate (63) to move, and the moving horizontal slide table (68) moves to drive the position of the sliding frame (67) to move, and the position of the sliding plate (63) and the sliding frame (67) Move to drive the position of the turning vane wheel (61) to move, and the turning vane wheel (61) rotates to stir the particles that have just been granulated and piled up together, preventing the granulation from sticking together and affecting subsequent use;

S5: When the particles are turned over, the heating pipe (72) generates heat and generates high temperature, which makes the plastic particles dry faster after granulation and will not stick together. When the turning blade wheel (61) is turning over It is also possible to vibrate the dust on the plastic granules, and the dust will fall into several dust collection fans (7) through the filtration of the dust removal screen (53), and the filtered dust will be adsorbed by the work of several dust collection fans (7). After the dust is absorbed, there will be no dust attached to the particles, and the small pieces of waste generated by granulation will affect the use of subsequent particles;

S6: After the particles are collected and dried, the two telescopic oil cylinders (54) shrink at the same time to drive the receiving seat (51) to rotate on the rotating seat (52), so that the receiving seat (51) is close to the collection box ( One end of 9) is inclined downwards, and the particles are inclined and dropped into the collection box (9) to complete the collection of particles;

S7: After the discharge is completed, the receiving seat (51) and the ash removal screen (53) can be cleaned through the operation of several cleaning fans (71).
