[0023] like Figure 3-4 As shown, this example allows for the easy manufacture of plastic pellets of different lengths.

[0024] The plastic granulator includes a turntable 101, a rotating frame 201, baffles 203, and blades 207. The turntable 101 is rotatably connected inside the rotating frame 201. A ring of forming openings 102 is provided on the turntable 101. Three baffles 203 contact the turntable 101. The blades 207 are welded to the rotating frame 201 and contact the turntable 101. Cooling pipes are provided inside the rotating frame 201. The turntable 101 is keyed to the output shaft of a first rotary motor, thus the first rotary motor can drive the turntable 101 to rotate within the rotating frame 201. The turntable 101 contains plastic raw material. When rotating, the plastic raw material is thrown into the molding hole 102. Then, the cooling pipe of the rotating frame 201 cools the plastic raw material at the molding hole 102 into a plastic column. Then, when the rotating plate 101 rotates, it can throw the plastic column out of the molding hole 102. Then, the blade 207 cuts the plastic column protruding from the rotating plate 101 into plastic particles. The longer the plastic column protrudes from the rotating plate 101, the longer the plastic particles are produced. Then, the baffle 203 can block the molding hole 102, causing the plastic column to protrude from the rotating plate 101 later, making the produced plastic particles shorter, thereby achieving the effect of facilitating the production of plastic particles of different lengths.

[0025] like Figure 5-6 As shown, this example allows for the easy lifting of the three baffles 203 one by one.

[0026] Since the plastic granulator also includes a support 202, rotating rods 204, and a rotating ring 205, the support 202 is welded to the top of the rotating frame 201. The three rotating rods 204 are rotatably connected to the support 202. The three baffles 203 are welded to the bottom of the three rotating rods 204 respectively. A push plate is welded to the bottom of each of the three rotating rods 204. The rotating ring 205 is rotatably connected to the support 202. The rotating ring 205 has an inclined surface. The left and right sides of the rotating ring 205 have different radii. As a result, the rotating ring 205 rotates around the support 202. The inclined surface of the rotating ring 205 pushes the push plate of the first rotating rod 204 upward. The push plate then drives the first baffle 203 and the first rotating rod 204 to push upward together. The rotating ring 205 continues to rotate, pushing the three baffles 203 upward in sequence, thus achieving the effect of easily lifting the three baffles 203 upward in sequence.

[0027] like Figure 3-6 As shown, this example allows for the easy placement of the three baffles 203 against the turntable 101.

[0028] Since the plastic granulator also includes tension springs 206, the three tension springs 206 are respectively welded and connected between the push plate and the bracket 202 of the corresponding rotating rod 204. Thus, the three tension springs 206 pull the three push plates toward the bracket 202, and the three push plates respectively drive the three baffles 203 and the three rotating rods 204 to press against the turntable 101, thereby achieving the effect of making it easy to press the three baffles 203 against the turntable 101.

[0029] like Figure 3-4 As shown, this example can facilitate the mixing of the added plastic stock solution.

[0030] Since the plastic granulator also includes a feed pipe 103, a circular sleeve 105, a rotating shaft 106, and stirring blades 107, the feed pipe 103 is screwed to the top of the turntable 101, the circular sleeve 105 is slidably connected inside the feed pipe 103, the rotating shaft 106 is rotatably connected inside the circular sleeve 105, and the three stirring blades 107 are welded to the rotating shaft 106. The rotating shaft 106 is keyed to the output shaft of the second rotary motor, so that the second rotary motor can drive the rotating shaft 106 to rotate in the circular sleeve 105, and the rotating shaft 106 drives the three stirring blades 107 to rotate together, so that the plastic raw liquid is poured in from the feed pipe 103, and the stirring blades 107 are rotated to stir the plastic raw liquid, thereby achieving the effect of making the added plastic raw liquid evenly stirred.

[0031] like Figure 3-4 As shown, this example allows for easy closure of the feed pipe 103.

[0032] Since the plastic granulator also includes a handle 104, which is rotatably connected above the feed pipe 103, the handle 104 is provided with a thread, and the sleeve 105 is threadedly connected inside the handle 104. The feed pipe 103 is provided with a perforated plate, and the rotating shaft 106 can be inserted into the perforated plate. By rotating the handle 104, the sleeve 105 can be driven to slide downward along the feed pipe 103. The sleeve 105 then drives the rotating shaft 106 to slide downward together. The rotating shaft 106 slides downward and inserts into the perforated plate of the feed pipe 103, thus preventing the plastic raw liquid from flowing out of the perforated plate of the feed pipe 103, thereby achieving the effect of easily sealing the feed pipe 103.

[0033] like Figure 3-8 As shown, this example can facilitate the cooling of plastic granules collected by funnel 302.

[0034] Since the plastic granulator also includes a support plate 301, a funnel 302, and a cooling box 303, a crossbeam is welded to the bottom of the rotating frame 201, the support plate 301 is welded to the bottom of the crossbeam of the rotating frame 201, the funnel 302 is screwed to the support plate 301, the funnel 302 is located below the blade 107, a cooling pipe is welded to the bottom of the funnel 302, and the cooling box 303 is welded to the bottom of the cooling pipe. The cooling pipe and the cooling box 303 are filled with coolant. As a result, the plastic granules processed by the blade 107 can fall into the funnel 302, and the funnel 302 sends the collected plastic granules into the cooling box 303 through the cooling pipe. The coolant in the cooling pipe and the cooling box 303 can cool down the plastic granules, thereby achieving the effect of facilitating the cooling of the plastic granules collected by the funnel 302.

[0035] like Figure 7-8 As shown, this example allows for easy discharge of the processed plastic granules from the outlet 306.

[0036] Since the plastic granulator also includes a conveying pipe 304, a spiral blade 305, and a discharge port 306, the conveying pipe 304 is screwed to the side of the cooling box 303, the spiral blade 305 is rotatably connected inside the conveying pipe 304, the discharge port 306 is welded to the bottom of the conveying pipe 304, and one end of the spiral blade 305 is keyed to the output shaft of the third rotary motor. Thus, the third rotary motor can drive the spiral blade 305 to rotate, and the spiral blade 305 can discharge the plastic granules in the cooling box 303 upward along the conveying pipe 304. The upward-moving plastic granules can slide down from the discharge port 306, thereby achieving the effect of discharging the processed plastic granules from the discharge port 306.

[0037] like Figure 7-10 As shown, this example can facilitate the sorting of defective products into waste bin 401.

[0038] Since the plastic granulator also includes support columns 307, waste pipe 308, and waste bin 401, the waste pipe 308 is welded to the bottom of the conveying pipe 304, two support columns 307 are welded to the bottom of the waste pipe 308, and the waste bin 401 is welded to the bottom of the cooling box 303. The waste bin 401 has an opening, and the opening of the waste bin 401 is screwed to the waste pipe 308. The conveying pipe 304 has a screen hole at the bottom. When the plastic granules are discharged upward along the conveying pipe 304, the defective products that are too small can fall into the waste pipe 308 through the screen hole of the conveying pipe 304. Then, the defective products slide from the waste pipe 308 into the opening of the waste bin 401, thereby achieving the effect of easily screening out the defective products.

[0039] like Figure 9-10 As shown, this example can facilitate the collection of defective products into the circular trough 407 for reuse.

[0040] Since the plastic granulator also includes baffles 406 and a circular trough 407, the circular trough 407 is slidably connected to the bottom of the waste bin 401, and the two baffles 406 are welded to the circular trough 407, the defective products can fall into the circular trough 407 from the opening of the waste bin 401, and the circular trough 407 can be pulled out of the waste bin 401. The defective products collected in the circular trough 407 can be processed into plastic raw material, thereby achieving the effect of facilitating the collection of defective products into the circular trough 407 for reuse.

[0041] like Figure 9-10 As shown, this example allows for the convenient removal of the circular groove 407 only after the waste bin 401 is sealed.

[0042] Since the plastic granulator also includes a rotating plate 402, a gear 403, a round shaft 404, and a T-shaped rod 405, a semi-circular plate is provided inside the waste bin 401. The rotating plate 402 is rotatably connected to the semi-circular plate, the round shaft 404 is welded to the rotating plate 402, and the round shaft 404 is rotatably connected to the waste bin 401. The rotating plate 402 is welded to the rotating plate 402, and the T-shaped rod 405 is slidably connected to the semi-circular plate. A rack is provided on the T-shaped rod 405, and the rack of the T-shaped rod 405 meshes with the gear 403 for transmission. Two through slots are provided on the T-shaped rod 405, and the two through slots of the T-shaped rod 405 are respectively inserted into the corresponding stop pins 406, thereby T... The T-shaped rod 405 restricts the movement of the two stoppers 406, thereby preventing the circular groove 407 from sliding. The rotating shaft 404 can drive the rotating plate 402 to rotate, sealing the waste box 401. The rotation of the rotating plate 402 drives the gear 403 to rotate together. The gear 403 drives the rack of the T-shaped rod 405 to move the T-shaped rod 405 downward. The two insert rods 406 separate from the through grooves on the corresponding T-shaped rods 405, allowing the insert rods 406 to move freely. The circular groove 407 can slide out of the waste box 401, thus achieving the effect of making it easy to remove the circular groove 407 only after the waste box 401 is sealed.
