[0020] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 3-8 ;

[0022] A plastic particle production device includes a processing cylinder 101, the upper end of the processing cylinder 101 is fixedly connected to a compression cylinder 301 by bolts, a push plate 303 is slidably connected inside the compression cylinder 301, a spring 302 is installed between the push plate 303 and the inner wall of the compression cylinder 301, a crossbeam is fixedly connected inside the processing cylinder 101 by bolts, a storage box 403 is rotatably connected to the crossbeam by an axis, a pressure plate 401 is slidably connected inside the storage box 403, a limiting plate 304 is welded to the compression cylinder 301, and the pressure plate 401 is slidably connected to the lower end of the limiting plate 304.

[0023] When using the production device, the staff first adds the cleaned recycled waste plastics into the storage box 403, and then controls the pressing plate 401 to slide into the compression cylinder 301, so that the pressing plate 401 and the push plate 303 cooperate to compress the waste plastics, and the compressed waste plastics enter the compression cylinder 301, and the push plate 303 slides into the compression cylinder 301. At the same time, the spring 302 is compressed by force, and with the cooperation of the compression cylinder 301, the waste plastics can be pressed into cylindrical plastic blocks. When the pressing plate 401 is separated from the compression cylinder 301, the push plate 303 can automatically pop out under the elastic action of the spring 302, and then the pressed cylindrical plastic blocks can be automatically unloaded.

[0024] During the process of pressing the waste plastics, the pressing plate 401 is separated from the side wall of the storage box 403, so that the storage box 403 rotates downward under the action of its own weight, so that the storage box 403 is in an inclined state. When the cylindrical plastic blocks are automatically unloaded, the pressing plate 401 does not return to the state of contact with the storage box 403. At this time, the cylindrical plastic blocks can automatically slide along the inner wall of the storage box 403 into the processing cylinder 101, waiting for further processing. When the pressing plate 401 is completely reset and contacts the side wall of the storage box 403, the storage box 403 can automatically rotate upward to a horizontal state, thereby facilitating the reception of the waste plastics.

[0025] Through the above operation, waste plastics can be pressed into cylindrical plastic blocks, which are convenient for subsequent crushing and processing, reduce the occupied space, shorten the crushing time, and further improve the efficiency of plastic particle production.

[0026] See also Figure 5 ;

[0027] The pressing plate 401 is fixed with a plurality of claws 402 by bolts. The plurality of claws 402 can increase the friction between the plastic and the pressing plate 401, so that the pressing plate 401 can avoid moving outward when squeezing the waste plastic, thereby facilitating compaction of the waste plastic.

[0028] See also Figure 7-8 ;

[0029] A grinding cone 104 is rotatably connected to the processing cylinder 101 via a bearing, a plurality of crushing teeth are fixedly connected to the surface of the grinding cone 104, a plurality of matching teeth are fixedly connected to the inner wall of the processing cylinder 101, and an angle gradually decreases from top to bottom between the surface of the grinding cone 104 and the inner wall of the processing cylinder 101.

[0030] When the cylindrical plastic block falls between the grinding cone 104 and the inner wall of the processing tube 101, the grinding cone 104 is controlled to rotate so that the multiple crushing teeth cooperate with the multiple matching teeth, thereby crushing the cylindrical plastic block. In addition, since the angle between the surface of the grinding cone 104 and the inner wall of the processing tube 101 gradually decreases from top to bottom, the volume of the crushed plastic gradually decreases as the plastic falls downward, thereby facilitating subsequent heating and melting treatment.

[0031] See also Figure 7-8 ;

[0032] A crankshaft 102 is rotatably connected to the crossbeam in the treatment cylinder 101 via a bearing, a push-pull rod 103 is rotatably connected to the crankshaft 102 via a bearing, and the push-pull rod 103 is rotatably connected to the pressure plate 401 .

[0033] By controlling the crankshaft 102 to rotate, the push-pull rod 103 pushes the pressing plate 401 forward and then pulls the pushing plate backward, so that the pressing plate 401 can realize the function of continuously pressing the waste plastics. While the crankshaft 102 rotates to realize the continuous pressing of the pressing plate 401 on the waste plastics, it can also drive the grinding cone 104 to crush the broken materials, making the overall process more consistent.

[0034] See also Figure 8 ;

[0035] The lower end of the processing cylinder 101 is cylindrical in shape, and an extrusion screw 201 is rotatably connected to the bottom of the processing cylinder 101 . Two discharge ports 202 are opened at the lower end of the processing cylinder 101 .

[0036] The crushed plastic falls to the bottom of the processing cylinder 101 through the gap between the grinding cone 104 and the processing cylinder 101. The bottom of the processing cylinder 101 is heated by an external heating device, so that the crushed plastic can be heated and melted. At the same time, the molten plastic can be transferred downward by controlling the rotation of the extrusion screw 201, and finally extruded through two discharge ports 202. The extruded strip plastic is cooled and cut to form plastic particles.

[0037] See also Figure 3 ;

[0038] The extrusion screw 201 is fixedly connected to the grinding cone 104. When the grinding cone 104 crushes the plastic, the molten plastic can be transmitted downward, thereby further improving production efficiency. There is no need to control the extrusion screw 201 separately, thereby avoiding the phenomenon of plastic accumulation.

[0039] See also Figure 3 ;

[0040] Guide plates are provided at both ends of the storage box 403 to guide the waste plastics so that the plastics can automatically slide to the center of the storage box 403, thereby facilitating the cooperation with the pressing plate 401 to press the waste plastics.

[0041] See also Figure 1 ;

[0042] The upper end of the processing cylinder 101 is fixedly connected to the driving motor 203 by bolts, and the crankshaft 102 is fixedly connected to the output shaft of the driving motor 203 by a coupling. The driving motor 203 drives the crankshaft 102 to rotate, thereby realizing the functions of pressing, crushing and extruding plastic at the same time.

[0044] Step 1: First, the cleaned recycled waste plastics are added into the storage box 403;

[0045] Step 2: Control the pressing plate 401 to slide into the compression cylinder 301, so that the pressing plate 401 cooperates with the push plate 303 to compress the waste plastics;

[0046] Step 3: The pressing plate 401 is separated from the compression cylinder 301, and the push plate 303 is automatically ejected under the elastic action of the spring 302, and the pressed cylindrical plastic block is automatically unloaded;
