[0019] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.
[0020] See also Figure 6-8 ,
[0021] A plastic granule processing device comprises a water cooling box 401, a return pipe 302 is welded on the water cooling box 401, two ports of the return pipe 302 are respectively connected to the left and right ends of the water cooling box 401, a fixed pipe 501 is welded on the return pipe 302, a collecting cover 502 is welded on the fixed pipe 501, an opening 503 is opened on the collecting cover 502, a net bag 504 is fixedly connected at the position of each opening 503, a sliding plug 506 is slidably connected in the fixed pipe 501, a filter screen 505 is fixedly connected to the sliding plug 506, and the filter screen 505 is conical 505, a water cooling mechanism is installed in the water cooling box 401, and a granulating mechanism is connected above the water cooling box 401.
[0022] When using the plastic particle processing device, the staff first adds cold water to the water cooling box 401, and then uses the water cooling mechanism to circulate the cold water in the water cooling box 401 through the reflux pipe 302. At this time, the plastic particles produced by the granulation mechanism fall into the water cooling box 401. The circulating cold water can be used to cool the plastic particles, thereby realizing the function of water cooling the plastic particles. When the plastic particles fall into the cold water, they are dispersed by the action of the water flow, thereby preventing the newly prepared plastic particles from piling up and sticking together.
[0023] The plastic particles can flow into the fixed pipe 501 along with the water flow, and the collecting cover 502 facilitates the plastic particles to enter the fixed pipe 501. Since the sliding plug 506 is slidably connected in the fixed pipe 501, the plastic particles can be blocked by the filter screen 505, and the cold water circulates normally through the filter screen 505. At this time, the sliding plug 506 is controlled to slide outward in the fixed pipe 501, thereby driving the plastic particles to move outward, and with the cooperation of the water flow, the plastic particles can enter the multiple net bags 504 through the multiple openings 503, thereby realizing the function of automatically collecting the plastic particles, and the collision of the plastic particles by the movement of the sliding plug 506 can break up the sticky plastic particles, thereby further improving the overall quality of the plastic particles.
[0024] Since the filter screen 505 is conical, the plastic particles are accumulated near the slide plug 506, thereby preventing the filter screen 505 from being blocked and affecting the water flow rate.
[0025] See also Figure 5 ,
[0026] The water cooling mechanism includes a first motor 301 , which is fixedly connected to the return pipe 302 . A propeller 303 is fixedly connected to the output shaft of the first motor 301 , and the propeller 303 is located at one of the ports of the return pipe 302 .
[0027] By controlling the first motor 301 to drive the propeller 303 to rotate, the propeller 303 rotates so that the water flows in a single direction, thereby realizing the circulation cooling function of the plastic particles.
[0028] See also Figure 7-8 ,
[0029] A guide plate 402 is welded at the bottom of the water cooling box 401. The guide plate 402 serves to guide the plastic particles. When the plastic particles fall into the water cooling box 401, the water flow pushes the plastic particles to move. The plastic particles can move along the inclined surface of the guide plate 402 to the collection cover 502 to prevent the plastic particles from running off.
[0030] See also Figure 1-5 ,
[0031] The granulation mechanism includes a granulation cylinder 101, which is fixedly connected to the upper end of the water cooling box 401 by bolts. A conveying screw 103 is rotatably connected to the granulation cylinder 101 through a bearing. The lower end of the granulation cylinder 101 is fixedly connected to a die head 104 by bolts. The die head 104 is provided with a plurality of circular holes. The lower end of the conveying screw 103 is fixedly connected to a cutter 105 by bolts. The cutter 105 is attached to the bottom of the die head 104.
[0032] The die head 104 extends into the cold water in the water cooling box 401, and the recycled plastic is added into the granulation barrel 101. The plastic in the granulation barrel 101 is heated by an external heating device, and the conveying screw 103 is controlled to rotate to convey the molten plastic downward, and finally extruded through a plurality of circular holes on the die head 104. The conveying screw 103 rotates while driving the cutter 105 to rotate, and the extruded strip plastic is cut into granules. The plastic granules are washed away by the flow of cold water, thereby achieving a rapid cooling effect and avoiding the phenomenon of the die head 104 being blocked by the plastic adhering to the plastic.
[0033] See also Figure 5 ,
[0034] A feed box 201 is welded on the granulation cylinder 101 , and the feed box 201 is communicated with the inside of the granulation cylinder 101 . A moving plate 204 is arranged inside the feed box 201 , and a plurality of levers are fixedly connected to the moving plate 204 by bolts.
[0035] The recycled plastic is crushed. Since the crushed plastic is fluffy, excess air will be generated inside the granulation barrel 101 during feeding, resulting in low production efficiency. During the feeding process, the device controls the moving plate 204 to slide back and forth in the feed box 201, so that multiple levers move the crushed plastic, thereby making the accumulated plastic more compact and reducing the presence of cavities, thereby further improving processing efficiency.
[0036] See also Figure 4 ,
[0037] The upper end of the granulation cylinder 101 is fixedly connected to the second motor 102 by bolts, the output shaft of the second motor 102 is fixedly connected to the crankshaft 202 by a coupling, the conveying screw 103 is fixedly connected to the crankshaft 202, the moving plate 204 is fixedly connected to the slot rod 203 by bolts, and the crankshaft 202 is slidably connected in the slide groove of the slot rod 203.
[0038] The crankshaft 202 is driven to rotate by the second motor 102, so that the crankshaft 202 drives the conveying screw 103 to rotate, thereby realizing the granulation function. At the same time, the rotation of the crankshaft 202 drives the groove rod 203 to produce reciprocating movement, and then drives the movable plate 204 to produce reciprocating movement, thereby realizing the function of moving the broken plastic. Through the above structure, the power of the rotation of the conveying screw 103 can be used to realize the function of controlling the movable plate 204, making the overall process more coherent and further simplifying the operation.
[0039] See also Figure 1 ,
[0040] One end of the filter screen 505 is fixedly connected to the slot rod 203 by bolts. When the slot rod 203 moves back and forth, it can synchronously drive the filter screen 505 and the sliding plug 506 to slide back and forth in the fixed tube 501, thereby realizing the functions of breaking up and automatically collecting the plastic particles. This linkage further simplifies the operation and improves the processing efficiency.
[0041] See also Figure 8 ,
[0042] The sliding plug 506 is made of rubber and has good wear resistance, which further improves the service life of the sliding plug 506.

[0044] Step 1: The recycled plastic is crushed, and the movable plate 204 is controlled to slide back and forth in the feed box 201, so that the multiple levers move the crushed plastic;
[0045] Step 2: The die head 104 extends into the cold water in the water cooling box 401 and adds the recycled plastic into the granulation cylinder 101;
[0046] Step 3: Use an external heating device to heat the plastic in the granulation cylinder 101, and control the conveying screw 103 to rotate to convey the molten plastic downward, and cut the extruded strip plastic into granules;
[0047] Step 4: Control the first motor 301 to drive the propeller 303 to rotate. When the propeller 303 rotates, the water flows in a single direction to circulate and cool the plastic particles.
[0048] Step 5: The sliding plug 506 is controlled to slide outward in the fixed tube 501 , thereby driving the plastic particles to move outward, and the plastic particles enter the multiple net bags 504 through the multiple openings 503 .
[0049] The plastic particles are processed by a plastic particle processing device, and the raw materials of the plastic particles include the following raw materials in weight fractions: 90 parts of recycled waste plastics, 2 parts of colorants and 3 parts of plasticizers.
