Wherein, the first positioning element 531 and the second positioning element 532 are both provided with a second positioning slot 531. The two ends of the cutter 42 perform the transverse movement in the second positioning groove 531, and in the process of the transverse movement of the second positioning groove 531, the vertical direction and the horizontal direction are both limited by the second positioning groove 531, so that the situation that the cutter 42 swings left and right or up and down due to the influence of self gravity when the cutter 42 moves out for a certain distance in the process of driving the cutter 42 by the second driving device 41 is avoided. If the cutting knife 42 is shifted left and right or up and down after moving, so that the overlapping accuracy of the material cutting opening 421 and the top block 521 in the vertical direction is poor, and the material cutting opening 421 is easily damaged by friction when the top block 521 descends and ejects the material particles in the material cutting opening 421.

In summary, the soft elastic resin material to be extruded is first installed in the storage tank 233 of the extruding device 2, and then the piston plate 22 enters the storage tank 233 from the first opening 231 and moves up and down in the vertical direction in the storage tank 233 by the first driving device 21. The piston sealing plate 222 is supported against the inner wall of the storage tank 233. At this time, the soft elastic resin material in the storage tank 233 is extruded from the discharge port 241 by the piston plate 22. The initial state of the cutter 42 is that the top of the cutter 42 is attached to the discharge port cover plate 24, and the bottom of the cutter 42 is attached to the cutter supporting block 43. At this time, the top of the material cutting opening 421 on the cutter 42 is overlapped and communicated with the material outlet 241 on the material outlet cover plate 24, and the bottom of the material cutting opening 421 on the cutter 42 is in a sealed state under the joint of the cutter supporting block 43. Next, when the material is extruded from the discharging port 241 of the discharging port cover plate 24 in the extruding device of the previous step, the material is extruded into the cutting port 421 through the discharging port 241 and fills the cutting port 421. After the extrusion is completed, the second driving device 41 will drive the cutter 42 to move in the horizontal direction. When the cutter 5 moves forward, the raw material can be cut off by the dislocation and the pulling force generated by the upper discharge port 241 and the lower discharge port 421, and the material cutting is completed. In the previous process, after the material is pushed into the material cutting opening 521, the cutter 42 cuts the soft elastic material, and the soft elastic material is filled in the material cutting opening 421, and then the second driving device 41 drives the cutter 42 to move to the lower side of the top plate 52, and at this time, the top block 521 on the top plate 52 and the material cutting block 521 on the cutter 42 are vertically overlapped. The third driving device 51 drives the top plate 52 to descend, the top block 521 descends to penetrate through the material cutting opening 421, and the material particles in the material cutting opening 421 are ejected out. Wherein, the cooling constant temperature storage device 3 is used for keeping the raw materials in the storage barrel 23 in a constant temperature and low temperature state, and prolonging the storage time of the raw materials. The granulator of this embodiment simple structure, convenient operation, degree of automation is high, and production efficiency is high, can produce the material grain of the unanimous size of material grain automatically.
