A control panel 101 is installed on the side of the feeding box 1 close to the human body. A feeding port 102 and a discharging port 104 are respectively provided on the two side walls of the feeding box 1. A partition 103 is fixed inside the feeding box 1. A through hole 1031 is provided on the partition 103. The through hole 1031 is on the same axis as the feeding port 102. There is a The jet pipe 201 is annular, and a plurality of overlapping arc plates 3 are arranged in the jet pipe 201. The top and bottom outer walls of the jet pipe 201 are fixed with mounting plates 2. The two mounting plates 2 are fixedly connected to the inner wall of the loading box 1. The overlapping surfaces of the plurality of overlapping arc plates 3 are flush with the bottom of the feed port 102. A connecting plate 302 is welded between the plurality of overlapping arc plates 3. The lower surfaces of the plurality of overlapping arc plates 3 and the connecting plate 302 are welded with a supporting plate 301. The thickness of 301 is smaller than the spacing between the jet pipes 201, and the bottom ends of the multiple support plates 301 are fixedly connected to the upper surface of the mounting plate 2 below, the discharge port 104 is connected to the feed port of the cutting box 7, and a cutting knife 5 is provided on the side of the partition 103 away from the feed port 102, and the cutting knife 5 contacts and is slidably connected to the end surface of the partition 103, and a hydraulic cylinder 501 is installed on the lower surface of the loading box 1 by bolts, and the telescopic end of the hydraulic cylinder 501 passes through the box wall and is fixedly connected to the bottom end of the cutting knife 5, and a conveyor belt 6 is provided on one side of the cutting knife 5, and baffles 601 are symmetrically provided on the upper surface of the conveyor belt 6, and one end of the conveyor belt 6 and the two baffles 601 pass through the discharge port 104 and are located in the cutting box 7, and the two baffles 601 are fixedly connected to the inner wall of the loading box 1 by connecting rods, and the end surfaces of the two baffles 601 are rotatably installed with a plurality of rollers 602, and the spacing between the two baffles 601 is greater than the diameter of the plastic strip;

After the continuously extruded and moving plastic strips enter the loading box 1, they are overlapped by the overlapping arc plates 3. At this time, the air pump 4 works to send external air into the air supply pipe 401 through the exhaust pipe 402, and sprays the passing plastic strips from the nozzle on the jet pipe 201 to cool the plastic strips. As the plastic strips are continuously pushed forward, they pass through the through hole 1031 of the partition 103 and penetrate into the top of the conveyor belt 6. At this time, the hydraulic cylinder 501 works, and its telescopic end pushes the cutting knife 5 to move upward along the partition 103 to cut the plastic strips. The cut plastic strips fall onto the conveyor belt 6, and enter the cutting box 7 from the discharge port 104 under the movement of the conveyor belt 6 for cutting and granulation operations.
