Two side ears 11 are symmetrically and fixedly connected to the inner wall of one side of the storage box 2. A sliding rod 12 is slidably installed between the inner parts of the side ears 11, and both ends of the sliding rod 12 are slidably installed inside the two sides of the storage box 2. A plurality of teeth 13 are installed at equal intervals on the top side of the sliding rod 12, and the teeth 13 mesh with the semi-gear 9. A connecting plate 14 is installed on the outer wall of one side of the sliding rod 12, and a stirring component is installed below the connecting plate 14;

[0024] The stirring assembly includes two rotating shafts 15 which are respectively rotatably installed inside both ends of the connecting plate 14. Driving wheels 16 and driven wheels 17 are respectively installed on the outer walls of the rotating shafts 15. The driving wheels 16 and the driven wheels 17 are cooperatively connected by a belt 18. A stirring motor 19 is installed on the top side of the connecting plate 14. One end of the rotating shaft 15 is cooperatively connected with the output end of the stirring motor 19. Three stirring blades 20 are equidistantly installed on the outer wall of the rotating shaft 15;

[0025] One side of the support plate 21 is installed with a control panel 37 which is used for operating and controlling the electrical components inside the device; during operation, in practical applications, the plastic particles in the storage box 2 will concentrate in a specific area and cannot fully contact the outside air, thus reducing the cooling efficiency of the plastic particles. The preliminarily cooled nylon plastic particles fall into the storage box 2. At this time, the driving motor 4 is started to drive the turntable 5 and the convex rod 6 to rotate. At the same time, the convex rod 6 slides in the chute 10, causing the connecting rod 8 to swing around the support rod 7. The semi-gear 9 at the bottom end of the connecting rod 8 also swings accordingly. Since the semi-gear 9 meshes with the teeth 13, the slide rod 12 can be pushed to slide left and right in the storage box 2, and the stirring assembly also moves left and right, expanding the stirring range and improving the material scattering effect and cooling efficiency of the plastic particles;

[0026] The stirring motor 19 is started to drive one of the rotating shafts 15 to rotate. The driving wheel 16 on this rotating shaft 15 drives the driven wheel 17 to rotate through the belt 18, so that the other rotating shaft 15 also rotates. The stirring blades 20 on the outer walls of the two rotating shafts 15 disperse and stir the nylon plastic particles, ensuring the uniformity of the particles and enabling the particles to fully contact the air, further improving the cooling efficiency.

[0027] Please refer to Figure 1 、 2 As shown in FIGS. 4 and 5, two support plates 21 are symmetrically and fixedly connected to one end of the top side of the main board 1. The top sides of the support plates 21 are jointly fixedly connected with an extrusion cylinder 22. One side of the extrusion cylinder 22 is installed with a motor 23. The output end of the motor 23 is installed with a rotating shaft 24. One end of the rotating shaft 24 penetrates through the inside of the extrusion cylinder 22. A spiral blade 25 is assembled on the outer wall of the rotating shaft 24;

[0028] Inside one end of the extrusion cylinder 22, an extrusion chamber 26 is fixedly connected. Inside the extrusion chamber 26, eight extrusion holes 27 are equidistantly arranged. One end of the rotating shaft 24 movably penetrates through the extrusion chamber 26 and four blades 28 are equidistantly installed. The outside of the extrusion cylinder 22 is connected with a connecting pipe 29. One end of the connecting pipe 29 is connected to the top end of the extrusion chamber 26 as a water inlet, and the other end of the connecting pipe 29 is connected to the bottom end of the extrusion chamber 26 as a water outlet. A cooling pump 30 is installed on the outer wall of the connecting pipe 29;

[0029] On the top side of one end of the extrusion cylinder 22, a feed hopper 31 is connected. Inside the feed hopper 31, two connecting shafts 32 are symmetrically and rotatably installed. Crushing rollers 33 are assembled on the outer walls of the connecting shafts 32. One end of each connecting shaft 32 is respectively equipped with a driving gear 34 and a driven gear 35, and the driving gear 34 and the driven gear 35 are meshed with each other. A crushing motor 36 is installed on one side of the feed hopper 31. One end of the connecting shaft 32 is in fit connection with the output end of the crushing motor 36; During operation, in the process of plastic modification and granulation, nylon is melted at high temperature and discharged from the discharge end of the extrusion barrel. If it is not cooled and scattered in time, the high-temperature nylon particles are prone to adhesion, seriously affecting the product quality. Therefore, a cooling and scattering device is needed. During granulation, the nylon plastic raw material is poured into the feed hopper 31, and the crushing motor 36 is started to drive the connecting shaft 32 to rotate. Since the driving gear 34 and the driven gear 35 are meshed with each other, the two connecting shafts 32 rotate inward simultaneously, driving the crushing rollers 33 to rotate accordingly, crushing the large nylon plastic raw material poured into the feed hopper 31 into smaller particles, which is convenient for subsequent extrusion granulation;

[0030] Before operation, the cooling pump 30 is started to make the cooling water circulate in the connecting pipe 29 and the extrusion chamber 26. The circulating cooling water preliminarily cools the plastic particles in the extrusion chamber 26 to prevent the particles from overheating and deforming or adhering. One end of the connecting pipe 29 is provided with a water inlet. During the operation process, the spiral blade 25 is a heating type spiral blade 25 of model TH-100. The crushed nylon plastic particles enter the extrusion cylinder 22. The motor one 23 is started to drive the rotating shaft 24 to rotate, and the spiral blade 25 rotates accordingly. The spiral blade 25 melts the raw material and pushes the melted nylon plastic forward in the extrusion cylinder 22. When it is pushed to the position of the extrusion chamber 26, under the action of pressure, the particles are extruded through the extrusion holes 27 to form strips. At the same time, the four blades 28 at one end of the rotating shaft 24 cut the extruded strip-shaped plastic into granular form.

[0031] Working principle: During granulation, pour the nylon plastic raw material into the feed hopper 31, start the crushing motor 36, drive the connecting shaft 32 to rotate. Since the driving gear 34 and the driven gear 35 mesh with each other, the two connecting shafts 32 rotate inward simultaneously, driving the crushing rollers 33 to rotate accordingly, crushing the large nylon plastic raw material poured into the feed hopper 31 into smaller particles, which is convenient for subsequent extrusion granulation.

[0032] Before operation, start the cooling pump 30 to make the cooling water circulate in the connecting pipe 29 and the extrusion cavity 26. The circulating cooling water preliminarily cools the plastic particles in the extrusion cavity 26 to prevent the particles from overheating and deforming or sticking. One end of the connecting pipe 29 is provided with a water inlet. During the operation process, the spiral blade 25 is a heating type spiral blade 25 with a model of TH - 100. The crushed nylon plastic particles enter the extrusion barrel 22. Start the first motor 23 to drive the rotating shaft 24 to rotate, and the spiral blade 25 rotates accordingly. The spiral blade 25 melts the raw material and pushes the melted nylon plastic forward in the extrusion barrel 22. When it is pushed to the position of the extrusion cavity 26, under the action of pressure, the particles are extruded through the extrusion holes 27 to form strips. At the same time, the four blades 28 at one end of the rotating shaft 24 cut the extruded strip-shaped plastic into granular form.

[0033] The preliminarily cooled nylon plastic particles fall into the storage box 2. At this time, start the driving motor 4 to drive the turntable 5 and the convex rod 6 to rotate. At the same time, the convex rod 6 slides in the chute 10, causing the connecting rod 8 to swing around the support rod 7. The semi-gear 9 at the bottom of the connecting rod 8 swings accordingly. Since the semi-gear 9 meshes with the teeth 13, it can push the slide rod 12 to slide left and right in the storage box 2, and the stirring assembly also moves left and right, expanding the stirring range and improving the material scattering effect and cooling efficiency of the plastic particles.

[0034] Start the stirring motor 19 to drive one of the rotating shafts 15 to rotate. The driving wheel 16 on this rotating shaft 15 drives the driven wheel 17 to rotate through the belt 18, so that the other rotating shaft 15 also rotates. The stirring blades 20 on the outer walls of the two rotating shafts 15 disperse and stir the nylon plastic particles, ensuring the uniformity of the particles and enabling the particles to fully contact with the air, further improving the cooling efficiency.
