[0028] Working principle: The material is first transported by the feeding mechanism 1. The frame 101 of the feeding mechanism 1 rotates the rotating roller 103 under the drive of the first reduction motor 105, thereby driving the climbing conveyor belt 104 to transport the material. The material plate 106 prevents the material from sliding. When the material reaches the top of the automatic flip-cover heating tank 2, the second servo motor 211 drives the active pulley 212, which drives the driven pulley 215 and the eccentric wheel 213 to rotate through the belt transmission. The eccentric wheel 213 drives the second rotating shaft 210 to rotate, and the second rotating shaft 210 drives the flip cover 209 to rotate along the hinge, thereby realizing the automatic opening and closing of the flip cover 209.

During the heating process, the first servo motor 205 drives the cage-shaped cleaning rack 204 to rotate, and the material is constantly turned over in the heating tank to achieve a uniform heating effect. At the same time, the cage-shaped cleaning rack 204 fits the inner surface of the heating tank 202, and can also prevent the material from adhering to the inner wall of the heating tank 202. The material flows into the screw conveyor 303 through the discharge pipe 311 and the first feeding port 312, and the material is fed into the extrusion barrel 302 through the first discharge port 304 and the second feeding port 305. The second reduction motor 308 drives the feeding rotating shaft 3 06, the feeding paddle 307 pushes the material evenly to the second discharge port 309 of the extrusion barrel 302, and the strip material is extruded through the mesh plate 310, and the extruded strip material falls into the cold water tank 4 arranged below through the second discharge port 309 for cooling, and the cooled strip material is transmitted to the automatic pelletizing device 5 for cutting, and the third servo motor 516 drives the fourth rotating shaft 502 to drive the first transmission roller 503 to rotate, and the first transmission roller 503 drives the third gear 506 to rotate, and the third gear 506 is meshed with the fourth gear 510, driving the fourth gear 510 to rotate, and the fourth gear 510 is meshed with the fifth gear 511, driving the fifth gear 511 to rotate, and the fifth gear 511 is meshed with another third gear 506, and the third gear 506 is meshed with the fourth gear 510. The fifth rotating shaft 504 is driven to rotate, and the fifth rotating shaft 504 drives the second transmission roller 505 to rotate. The cooled strip material passes between the second transmission roller 505 and the first transmission roller 503. The fourth servo motor 526 drives the fourth pulley 527 to rotate, and drives the third pulley 525 to rotate through the belt, thereby driving the transmission shaft 524 to rotate. The transmission shaft 524 drives the two second bevel gears 523 to rotate. The second bevel gears 523 are meshed with the first bevel gear 522. The two first bevel gears 522 rotate at the same time. The first bevel gear 522 drives the screw rod 521 to rotate. Since the two longitudinal tool fixing blocks 519 are respectively connected to the left and right threads of the screw rod 521, the two longitudinal tool fixing blocks 519 move in opposite directions along the slide rail 517 at the same time.A pelletizing cutter 520 is installed between the two horizontal cutter fixing blocks 519. The two pelletizing cutters 520 move in opposite directions at the same time to pelletize the cooled strip material. The third connecting rod 512 is driven to rotate by the cylinder 513. The third connecting rod 512 rotates along the rotating axis of the inner wall of the box body 501, driving the fifth rotating shaft 504 to slide upward along the sliding groove 515. At this time, the angle between the first connecting rod 507 and the second connecting rod 508 will decrease, ensuring that the first transmission roller 503 will transmit the gear to the second transmission roller 505. At the same time, the distance between the first transmission roller 503 and the second transmission roller 505 can also be controlled.
