[0003] Conventional plastic recycling machines include crushers, extruders, cooling tanks, and granulators. These machines are often arranged in a linear manner, which takes up a lot of space. When producing high-value PC plastic parts, scraps and defective products are often left. To save space, these plastics are often not recycled.

[0004] At the same time, before recycling the plastic, it needs to be cleaned and dried to ensure the quality of the extruded plastic and reduce cavitation during the extrusion process. Summary of the Invention

[0014] The feeding device includes a material guide sleeve 1, a first porous tube, and a second porous flushing tube. The feeding port of the material guide sleeve 1 is connected to the bottom of the crusher. The first porous tube corresponds to the position of the first cleaning tank, and the second cleaning tank corresponds to the position of the second porous flushing tube. The material guide sleeve 1 is rotatably connected to a material feeding spiral plate 1, a material beating plate, a material feeding spiral plate, and a shaft sleeve. The material feeding spiral plate 1 extends to the connection between the first cleaning tank and the second cleaning tank. The material feeding spiral plate is located on the side of the second cleaning tank away from the first cleaning tank. The material beating plate is located between the material feeding spiral plate 1 and the first porous tube.

[0015] The punching plate is composed of a plurality of arc-shaped plates arranged at intervals, and the pitch of the second porous flushing pipe is smaller than the pitch of the first feeding spiral plate.

[0016] The shaft sleeve is located outside the second cleaning tank away from the first cleaning tank. The outside of the shaft sleeve is fixedly connected to at least one discharge plate, and the end of the guide sleeve is fixedly connected to a water baffle.

[0017] The guide sleeve is ball-hinged at one end close to the discharge plate to form a guide shaft. The guide shaft is eccentrically arranged with the guide sleeve. The other end of the guide shaft is ball-hinged with the inner wall of the crushing and cleaning bin, and the end is concentric with the axis of the guide sleeve. The outer side of the guide shaft is fixedly connected to a guide pipe, a water-permeable hole is opened on the guide pipe, and a plurality of flipping plates are arranged at intervals on the inner side of the guide pipe.

[0020] A PC engineering plastic recycling system, which is installed on a PC engineering plastic recycling cabinet and is used to fully automatically recycle defective products produced in the factory;

[0021] By recycling the defective products and scraps generated in the factory production, they are fed into the crusher through the feed port;

[0022] The pulverizer is driven by an external motor to crush the plastic in the pulverizer;

[0023] The crushed plastic is fed into the cleaning tank through the feeding device and ultrasonically cleaned in the first cleaning tank, and then rinsed twice in the second cleaning tank;

[0024] The cleaned plastic is placed in the guide tube, and as the guide tube rotates eccentrically, most of the moisture is removed, and the scraps are fed into the air drying bin;

[0025] As the porous rotary belt rotates, the plastic is lifted by the lifting bucket. During this process, the plastic is further dried under the blowing of the fan three. The plastic is then guided by the feeding device two into the second drying chamber and further dried in the second drying chamber.

[0026] The plastic in the second drying chamber is melted by a plastic extruder and pushed into a granulating device to be extruded into multiple long strips. The cold zone of the plastic is gradually solidified by the granulating device, and part of the heat dissipated in this process is input into the air drying chamber.

[0027] The cooled plastic strips are cut and granulated by a granulating device.

[0028] The technical effects achieved by the present invention are:

[0029] The present invention pushes the plastic crushed objects into the first cleaning tank under the rotation of the feeding spiral plate, and removes the dirt on the surface of the plastic crushed objects under ultrasonic cleaning. As the feeding spiral plate pushes the plastic crushed objects, the plastic crushed objects are pushed into the second porous flushing pipe. At this time, the plastic crushed objects in the second porous flushing pipe are flushed by the flushing pipe, and the plastic crushed objects are turned over by the punching plate, so as to achieve the cleaning effect of the plastic crushed objects. Finally, the plastic crushed objects are lifted by the discharge plate under the guidance of the feeding spiral plate and transported to the guide pipe on the top of the water baffle. The feeding component and the cleaning component are combined to reduce the space occupied.

[0030] The present invention uses an electric push rod to reciprocate and drag the collection chamber to slide on the blocking strip, and pushes the screw rod to slide on the support frame, thereby driving the screw rod to rotate, and through the transmission card table and the screw rod transmission contact, synchronously drives the material rod to rotate, thereby avoiding the plastic crushed objects in the collection chamber from becoming compacted.

[0031] In the present invention, the plastic crushed objects rotate at intervals with the porous rotary belt, so that the lifting bucket vibrates with inertia, further drains the plastic crushed objects, and performs the first air-drying of the plastic crushed objects under the blowing of wind in the porous rotary belt. At the same time, the longer rotating path ensures the drying time of the plastic crushed objects, and at the same time completes the height lifting of the plastic crushed objects, and saves space compared with the transmission lifting component.

[0058] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0059] like Figure 1-16 As shown, a PC engineering plastic recycling cabinet includes a crusher 4, a plastic extruder 13, a granulation bin 1, a crushing and cleaning bin 3, and an interlayer air-drying bin 2 between the granulation bin 1 and the crushing and cleaning bin 3;

[0060] A crusher 4 is provided in the crushing and cleaning bin 3. The bottom of the crusher 4 is connected to a feeding device 6. The feeding device 6 passes through the cleaning pool 5 and is connected to the air-drying bin 2. A water hole is provided at the position of the feeding device 6 corresponding to the cleaning pool 5.

[0061] A plastic extruder 13 is provided in the granulation bin 1, and a granulation device 8 is provided at the discharge end of the plastic extruder 13, and the granulation device 8 is used to cool the plastic;

[0062] The pelletizing bin 1 is close to one side of the air drying bin 2 and is located on the upper and lower sides of the pelletizing device 8, and is provided with a fan 3 12;

[0063] The air drying bin 2 includes a porous rotating belt 201, the inner side of the porous rotating belt 201 is connected to the air outlet of the fan 3 12, and multiple groups of driving wheels 202 are arranged on the inner and outer sides of the porous rotating belt 201. The porous rotating belt 201 is transmission-connected to the driving wheels 202, and any group of driving wheels 202 is driven by a stepper motor. Multiple lifting buckets 203 are hinged on the inner side of the porous rotating belt 201, and the bottom surface of the lifting bucket 203 is provided with a through hole. The bottom side of the lifting bucket 203 is provided with a spring 1 204, and the spring 1 204 supports the lifting bucket 203 to swing around the hinge.

[0064] Furthermore, one side of the lifting bucket 203 is bent outward to form an inclined surface, so that the plastic crushed objects in the lifting bucket 203 can flow out more easily due to gravity when the lifting bucket 203 moves to the top of the porous rotary belt 201.

[0065] Furthermore, one end of spring 1 204 is fixed to the lifting bucket 203, and the other end is fixed to the porous rotary belt 201. When the lifting bucket 203 moves downward with the rotating opening of the porous rotary belt 201, the spring 1 204 pulls the lifting bucket 203 to prevent the opening of the lifting bucket 203 from fitting into the porous rotary belt 201, making it impossible to shovel plastic crushed objects more conveniently at the bottom side of the porous rotary belt 201.

[0066] Furthermore, a discharge port 15 is provided at the bottom side of the granulation bin 1, and a shield is provided outside the discharge port 15 to prevent heat loss in the granulation bin 1. A pellet collecting bin 11 is provided inside the discharge port 15, and the pellet collecting bin 11 is used to accumulate plastic pellets.

[0067] Furthermore, a feeding port 14 is provided on the top of the crushing and cleaning bin 3, which is higher than the feeding port of the crusher 4, to prevent crushed objects from flying out and workers from coming into contact with the crusher 4, thereby improving the overall safety of the device.

[0068] Furthermore, the top of the crusher 4 is a pouring bin, the middle is a crushing bin, and the bottom is a spiral guide shaft.

[0069] Furthermore, the pulverizer 4 is driven by an external motor, and through a transmission belt, it synchronously drives the feeding device 6, the feeding device 2 7, and the spiral guide shaft to rotate synchronously.

[0070] Refer to the attached Figure 8 To the attached Figure 10A plurality of guide metal sheets 205 are fixedly connected to the outside of the porous rotary belt 201. The guide metal sheet 205 is constructed such that the middle part of the metal sheet protrudes toward one side. Guide plates 206 are provided on both sides of the long side of the porous rotary belt 201. The guide plates 206 are fixedly connected between the granulation bin 1 and the crushing and cleaning bin 3. The two ends of the guide metal sheet 205 are slidably connected in the guide plates 206. A steering support wheel 207 is provided on the inside of the porous rotary belt 201. The steering support wheel 207 is supported on the inner side of the porous rotary belt 201 and makes the porous rotary belt 201 square.

[0071] Furthermore, gears that transmit each other are provided on one side of the same group of driving wheels 202, and a friction surface is rolled on the edge of the porous rotating belt 201 corresponding to the driving wheel 202 to facilitate the rotation of the porous rotating belt 201.

[0072] Furthermore, the driving wheel 202 starts and stops at intervals during operation, so that the lifting bucket 203 vibrates with inertia to further drain water.

[0073] Furthermore, a heating wire is provided in the lifting bucket 203 so that when the machine is just started, the temperature in the air drying chamber 2 is relatively low, making it impossible to completely remove the moisture on the surface of the plastic crushed objects.

[0074] Furthermore, wedge-shaped blocks are fixedly connected to the top and bottom of the guide plate 206 to support and guide the two ends of the guide metal sheet 205, making it easier to slide into the guide groove of the guide plate 206.

[0075] According to the above structure, the driving wheel 202 is driven to rotate by a stepper motor, and under the guidance of the guide plate 206 and the steering support wheel 207, the porous rotary belt 201 is driven to rotate, thereby driving the lifting bucket 203 on the inside of the porous rotary belt 201 to shovel out a certain amount of plastic crushed materials from the bottom side of the porous rotary belt 201, and further drain water as the lifting bucket 203 moves upward, and the plastic crushed materials are blown for the first time under the wind blowing in the porous rotary belt 201. When the lifting bucket 203 moves to the top of the porous rotary belt 201, the opening of the lifting bucket 203 is in a vertical state, and the plastic crushed materials in the lifting bucket 203 are flowed into the feeding device 2 7 under the inclined slope of the edge of the lifting bucket 203.

[0076] Refer to the attached Figure 5 and attached Figure 6The cleaning pool 5 includes a first cleaning pool 501, a second cleaning pool 504 is provided on one side of the first cleaning pool 501, the other side of the first cleaning pool 501 is connected to the filter 10, a shower pipe 503 is coiled around the second cleaning pool 504, the input port of the shower pipe 503 extends to the outside of the crushing and cleaning bin 3, the output port of the shower pipe 503 is connected to the solenoid valve 502, and the output port of the solenoid valve 502 is connected to the first cleaning pool 501.

[0077] Furthermore, the first cleaning tank 501 is an ultrasonic cleaning tank.

[0078] Furthermore, when the device just starts to work, water flows into the shower pipe 503 and enters the first cleaning tank 501 through the solenoid valve 502.

[0079] Furthermore, a liquid level sensor is provided in the first cleaning tank 501 , and the level of the liquid level sensor of the first cleaning tank 501 is lower than the level of the end of the water baffle 609 .

[0080] Furthermore, when in working state, the flushing pipe 503 discharges flushing water to the second porous flushing pipe 604, and the filter 10 connected to the bottom of the first cleaning tank 501 discharges water flow per unit time at a flow rate similar to the water flow injected into the second cleaning tank 504 by the flushing pipe 503, and the output water flow of the filter 10 can be controlled by the liquid level sensor.

[0081] Furthermore, as the second cleaning pool 504 is injected with water from the shower pipe 503 , excess water flows into the first cleaning pool 501 through the feeding device 6 and is discharged through the filter 10 .

[0082] Refer to the attached Figure 6 and attached Figure 7 The feeding device 6 includes a guide sleeve 601, a first porous tube 603, and a second porous flushing tube 604. The feeding port of the guide sleeve 601 is connected to the bottom of the crusher 4. The first porous tube 603 corresponds to the position of the first cleaning tank 501, and the second cleaning tank 504 corresponds to the position of the second porous flushing tube 604. The guide sleeve 601 is rotatably connected with a feeding spiral plate 602, a beating plate 605, a feeding spiral plate 606, and a shaft sleeve 607. The feeding spiral plate 602 extends to the connection between the first cleaning tank 501 and the second cleaning tank 504. The feeding spiral plate 606 is located on the side of the second cleaning tank 504 away from the first cleaning tank 501. The beating plate 605 is located between the feeding spiral plate 602 and the first porous tube 603. The beating plate 605 is composed of multiple arc-shaped plates arranged at intervals. The pitch of the second porous flushing tube 604 is smaller than the pitch of the feeding spiral plate 602.

[0083] The shaft sleeve 607 is located outside the second cleaning tank 504 away from the first cleaning tank 501. The outer side of the shaft sleeve 607 is fixedly connected to at least one discharge plate 608, and the end of the guide sleeve 601 is fixedly connected to a water baffle 609.

[0084] Furthermore, there is a gap between adjacent beating plates 605 , and the beating plates 605 are arranged in a spiral shape as a whole, and the pitch of the beating plates 605 is smaller than the pitch of the feeding spiral plate 1 602 .

[0085] Furthermore, since the pitch of the punching plate 605 and the pitch of the feeding spiral plate 606 are smaller than the pitch of the guide sleeve 601, the residence time of the plastic crushed objects is extended, and at the same time, the plastic crushed objects are accumulated in the second porous flushing tube 604, and as the punching plate 605 turns over the plastic crushed objects, the flushing effect of the plastic crushed objects is guaranteed.

[0086] Furthermore, the water level of the material guiding sleeve 601 is lower than the top of the water baffle 609.

[0087] Furthermore, the guide tube 611 is trumpet-shaped, and the inclined surface facilitates the guidance of the plastic crushed objects.

[0088] According to the above structure, the plastic crushed objects are pushed into the first cleaning tank 501 under the rotation of the feeding spiral plate 602, and the dirt on the surface of the plastic crushed objects is removed under ultrasonic cleaning and discharged from the through holes of the first porous tube 603. As the feeding spiral plate 602 pushes the plastic crushed objects, the plastic crushed objects are pushed into the second porous flushing tube 604. At this time, the plastic crushed objects in the second porous flushing tube 604 are flushed by the flushing pipe 503, and the plastic crushed objects are turned over by the punching plate 605 to achieve the cleaning effect of the plastic crushed objects. Finally, the plastic crushed objects are lifted by the discharge plate 608 under the guidance of the feeding spiral plate 606 and transported to the guide tube 611 at the top of the water baffle 609.

[0089] Refer to the attached Figure 6 The guide sleeve 601 is ball-hinged at one end near the discharge plate 608 to connect with the guide shaft 610. The guide shaft 610 is eccentrically arranged with the guide sleeve 601. The other end of the guide shaft 610 is ball-hinged with the inner wall of the crushing and cleaning bin 3, and the end is concentric with the axis of the guide sleeve 601. The outer side of the guide shaft 610 is fixedly connected with a guide pipe 611. A water-permeable hole is provided on the guide pipe 611. A plurality of flipping plates 612 are arranged at intervals on the inner side of the guide pipe 611.

[0090] Furthermore, the provided flipping plate 612 can lift the plastic crushed objects on the inner wall of the guide tube 611 and, after reaching a certain height, drop them downward to shake off the moisture. At the same time, it can prevent the plastic crushed objects from sliding and increase the time the plastic crushed objects stay in the guide tube 611.

[0091] According to the above structure, during the process of guiding the cleaned plastic crushed objects, the guide sleeve 1 601 rotates synchronously with the rotation of the guide sleeve 1. Since the hinge between the guide shaft 610 and the guide sleeve 1 601 is an eccentric hinge, each rotation of the guide tube 611 causes the plastic crushed objects to vibrate, thereby improving the removal of moisture attached to the surface of the plastic crushed objects.

[0092] Refer to the attached Figure 4 and attached Figure 11 The feeding device 2 7 includes a material receiving plate 701, which is located at the top of the air-drying bin 2. The granulating bin 1 is rotatably connected to the material receiving plate 701. The outer side of the spiral shaft 704 is sleeved with a material guide pipe 2 702. The end of the material guide pipe 2 702 is fixedly connected to a fan 1 703. A through hole is provided on the surface of the spiral sheet of the spiral shaft 704, and a discharge hole is provided on the side of the material guide pipe 2 702 close to the fan 1 703.

[0093] Furthermore, the fan 1 703 can further dry the plastic crushed materials in the guide pipe 2 702, and at the same time introduce the hot and humid air accumulated on the top of the granulation bin 1 into the air drying bin 2 and discharge it to the outside air.

[0094] According to the above structure, the plastic crushed objects on the surface of the receiving plate 701 are pushed to the discharge hole at the end of the second guide pipe 702 by the rotation of the screw shaft 704, and the plastic crushed objects are sent into the second drying chamber 9 through the discharge hole.

[0095] Refer to the attached Figure 4 and attached Figures 15 to 16 The second drying chamber 9 includes a collecting chamber 901, which is slidably connected to the top side of the granulation bin 1. The collecting chamber 901 is necked from top to bottom, and a sealing strip 903 is slidably inserted at the bottom of the feeding rod 904. The sealing strip 903 is provided with a feeding hole 906 at the position of the feeding hole of the plastic extruder 13. The front and rear sides of the bottom of the collecting chamber 901 are fixedly connected with a second fan 902. The bottom of the collecting chamber 901 is rotatably connected with the feeding rod 904, and the side of the feeding rod 904 close to the feeding hole 906 is fixedly connected with a transmission card platform 905, and the side of the feeding hole 906 away from the collecting chamber 901 is fixedly connected with a support frame 909. A screw rod 907 is adapted on the support frame 909, and a spring 908 is provided between the screw rod 907 and the support frame 909. The transmission card platform 905 corresponds to the end of the screw rod 907.

[0096] Furthermore, a material guide rod and an electric push rod are provided on the outside of the material collection chamber 901 for pushing the material collection chamber 901 to slide on the blocking strip 903 .

[0097] Furthermore, during the process of collecting materials in the collection chamber 901, air is blown into the collection chamber 901 by the second fan 902 to further dry the plastic crushed materials in the collection chamber 901. When the materials in the collection chamber 901 are full, the collection chamber 901 is dragged toward the clinker port of the plastic extruder 13 under the operation of the electric push rod.

[0098] Furthermore, the feed hole 906 is close to one side of the collection chamber 901, and the groove protrudes toward the side of the collection chamber 901. By controlling the intersection of the feed hole 906 and the bottom of the collection chamber 901, the size of the clinker port for feeding the plastic extruder 13 is controlled to avoid the plastic crushed materials from being fed too quickly and overflowing from the top of the plastic extruder 13.

[0099] Furthermore, a plurality of levers of different lengths are fixedly connected to the surface of the knocking rod 904 .

[0100] Furthermore, the ends of the screw rod 907 and the transmission card table 905 are provided with mutually engaging protrusions. When the screw rod 907 contacts the transmission card table 905, the screw rod 907 can drive the transmission card table 905 to rotate in one direction. Preferably, the contact surface of the screw rod 907 and the transmission card table 905 is provided with a plurality of wedge blocks with opposite inclined surfaces.

[0101] Furthermore, a fixed roller screw sleeve is provided at the connection between the support frame 909 and the screw rod 907.

[0102] According to the above structure, when the collecting chamber 901 moves to the position corresponding to the feeding hole 906, the crushed plastic in the collecting chamber 901 flows into the feeding port of the plastic extruder 13 under the action of gravity;

[0103] When the plastic fragments at the bottom of the collection chamber 901 accumulate and become compacted, the collection chamber 901 is dragged back and forth by the electric push rod to slide on the blocking strip 903, and the screw rod 907 is pushed to slide on the support frame 909, thereby driving the screw rod 907 to rotate, and the protruding block on the contact surface of the screw rod 907 and the transmission card table 905 drives the punching rod 904 to rotate synchronously, thereby disrupting the compacted part of the accumulated plastic fragments. By driving the punching rod 904 to rotate during the feeding process to the plastic extruder 13, the plastic fragments in the collection chamber 901 can be prevented from becoming compacted.

[0104] Refer to the attached Figure 4 and attached Figures 12 to 14The granulation device 8 includes a strip making mold 801, which is connected to the output end of the plastic extruder 13. Heat dissipation structures 803 are attached to both sides of the strip making mold 801. A heat dissipation fan 805 is fixedly connected to the away side of the heat dissipation structure 803. The air inlet end of the heat dissipation fan 805 is provided with an air duct 802. The air duct 802 is connected to the outside of the granulation bin 1. A water pipe 804 is connected to one side of the heat dissipation structure 803. The output end of the strip making mold 801 is fixedly connected to a cutter fixing frame 806. A rotary disk 807 is rotatably connected to the cutter fixing frame 806. A cutting blade 808 is slidably connected to the cutter fixing frame 806. The rotary disk 807 and the cutting blade 808 are transmission-connected by a push rod 810. The rotary disk 807, the cutting blade 808, and the push rod 810 form a crank slider component. A particle guide plate 809 is provided on the outside of the cutting blade 808.

[0105] Furthermore, the water outlet of the water pipe 804 is connected to the water inlet of the shower pipe 503 .

[0106] Furthermore, the cooling fan 805 is used to dissipate the heat of the plastic in the strip making mold 801, and dissipate the heat into the granulation bin 1, and input it into the air drying bin 2 as the fan 3 12 works, and finally discharged from the air drying bin 2 to the external control.

[0107] Furthermore, the hot water outputted by the water pipe 804 flows into the cleaning tank 5 as the operation progresses, so that the water in the first cleaning tank 501 becomes hotter as the operation time progresses, thereby further improving the cleaning effect on the plastic fragments.

[0108] Furthermore, a stepping motor is provided on one side of the turntable 807 for driving the turntable 807 to rotate and controlling the rotation speed of the turntable 807 to control the length of the plastic particles.

[0109] According to the above structure, the plastic extruder 13 extrude the plastic melt, which is introduced into the strip-making mold 801 and extruded into long strips. As the heat dissipation structure 803 and the heat dissipation fan 805 cool the plastic strips, the plastic strips harden. Then, the cutting blade 808 cuts the plastic strips to make plastic particles. At this time, the plastic particles fly outward under the guidance of the blade and flow into the particle collecting bin 11 under the guidance of the particle guide plate 809.

[0110] The working principle of the present invention is:

[0111] The defective products and scraps generated during factory production are recycled and fed into the crusher 4 through the feed port 14;

[0112] The pulverizer 4 is driven by an external motor to crush the plastic in the pulverizer 4;

[0113] The crushed plastic is fed into the cleaning tank 5 through the feeding device 6. The feeding spiral plate 602 rotates to push the crushed plastic into the first cleaning tank 501. Under ultrasonic cleaning, dirt on the surface of the crushed plastic is removed and discharged from the through-holes of the first porous pipe 603. As the feeding spiral plate 602 pushes the crushed plastic, the crushed plastic is pushed into the second porous flushing pipe 604. At this time, the flushing pipe 503 flushes the crushed plastic in the second porous flushing pipe 604. At the same time, the punching plate 605 flips the crushed plastic to achieve the cleaning effect of the crushed plastic. Finally, under the guidance of the feeding spiral plate 606, the crushed plastic is lifted by the discharge plate 608 and transported to the guide pipe 611 on the top of the water retaining plate 609.

[0114] During the process of guiding the cleaned plastic crushed materials, the guide sleeve 1 601 rotates synchronously with the rotation of the guide sleeve 1. Since the guide shaft 610 and the guide sleeve 1 601 are hinged at an eccentric joint, each rotation of the guide pipe 611 causes the plastic crushed materials to vibrate, thereby improving the removal of moisture attached to the surface of the plastic crushed materials. Under the guidance of the guide pipe 611, the crushed materials are fed into the air-drying chamber 2.

[0115] As the porous rotary belt 201 rotates, the plastic crushed objects drive the lifting bucket 203 on the inner side of the porous rotary belt 201 to scoop out a certain amount of plastic crushed objects from the bottom side of the porous rotary belt 201, and further drain water as the lifting bucket 203 moves upward, and the plastic crushed objects are dried for the first time under the blowing of the wind in the porous rotary belt 201. When the lifting bucket 203 moves to the top of the porous rotary belt 201, the opening of the lifting bucket 203 is in a vertical state, and the plastic crushed objects in the lifting bucket 203 flow into the feeding device 2 7 under the inclined surface of the edge of the lifting bucket 203. Under the rotation of the screw shaft 704, the plastic crushed objects on the surface of the receiving plate 701 are pushed to the discharge hole at the end of the guide pipe 2 702, and the discharge hole sends the plastic crushed objects into the second drying chamber 9;

[0116] The plastic in the second drying chamber 9 is melted by the plastic extruder 13, and the plastic melt is extruded by the plastic extruder 13, introduced into the strip-making mold 801, and extruded into long strips. As the heat dissipation structure 803 and the heat dissipation fan 805 cool the plastic strips, the plastic strips are hardened. Thereafter, the plastic strips are cut by the cutting blade 808 to form plastic particles. At this time, the plastic particles fly outward under the guidance of the blade and flow into the particle collecting bin 11 under the guidance of the particle guide plate 809, completing the collection of the plastic particles and making it convenient for workers to carry them.

[0117] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
