[0018] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0019] like Figure 1-16As shown, a PC engineering plastic recycling cabinet includes a pulverizer 4, a plastic extruder 13, a granulation bin 1, a pulverization and cleaning bin 3, and an interlayer air-drying bin 2 is provided between the granulation bin 1 and the pulverization and cleaning bin 3; A pulverizer 4 is arranged in the pulverizing and cleaning bin 3, and a feeding device 6 is connected to the bottom of the pulverizer 4. The feeding device 6 passes through the cleaning pool 5 and is connected to the air-drying bin 2. A water hole is opened at the position of the feeding device 6 corresponding to the cleaning pool 5. A plastic extruder 13 is arranged in the granulation bin 1, and a granulation device 8 is arranged at the discharge end of the plastic extruder 13, and the granulation device 8 is used to cool the plastic; 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; 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 204, and the spring 204 supports the lifting bucket 203 to swing around the hinge.

[0020] 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.

[0021] Furthermore, one end of spring 1 204 is fixed to the lifting bucket 203, and the other end is fixed to the porous rotating belt 201. When the lifting bucket 203 moves downward with the rotating opening of the porous rotating belt 201, the spring 1 204 pulls the lifting bucket 203 to prevent the opening of the lifting bucket 203 from fitting against the porous rotating belt 201, making it impossible to shovel plastic crushed objects more conveniently at the bottom side of the porous rotating belt 201.

[0022] 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.

[0023] Furthermore, a feeding port 14 is provided on the top of the crushing and cleaning bin 3, and the feeding port 14 is higher than the feeding port of the crusher 4, so as to prevent the crushed objects from flying out and the workers from coming into contact with the crusher 4, thereby improving the overall safety of the device.

[0024] Furthermore, the top of the pulverizer 4 is a pouring bin, the middle is a pulverizing bin, and the bottom is a spiral guide shaft.

[0025] 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.

[0026] See attached Figure 8 To Attachment Fig.10 A plurality of guide metal sheets 205 are fixedly connected to the outer side of the porous rotating 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 arranged on both sides of the long side of the porous rotating belt 201. The guide plates 206 are fixedly connected between the granulating bin 1 and the crushing and cleaning bin 3. Both ends of the guide metal sheet 205 are slidably connected in the guide plates 206. A steering support wheel 207 is arranged on the inner side of the porous rotating belt 201. The steering support wheel 207 is supported on the inner side of the porous rotating belt 201 and makes the porous rotating belt 201 square.

[0027] Furthermore, mutually transmitting gears are arranged on one side of the same group of driving wheels 202, and a friction surface is rolled at the edge of the porous rotating belt 201 corresponding to the driving wheel 202 to facilitate driving the porous rotating belt 201 to rotate.

[0028] 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.

[0029] 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.

[0030] Furthermore, wedge 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 .

[0031] 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 revolving belt 201 is driven to rotate, thereby driving the lifting bucket 203 on the inner side of the porous revolving belt 201 to shovel out a certain amount of plastic crushed materials from the bottom side of the porous revolving 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 in the porous revolving belt 201. When the lifting bucket 203 moves to the top of the porous revolving belt 201, the opening of the lifting bucket 203 is in a vertical state, and the plastic crushed materials in the lifting bucket 203 flow into the feeding device 27 under the inclined slope of the edge of the lifting bucket 203.

[0032] See attached Figure 5 and attached Figure 6The cleaning pool 5 includes a first cleaning pool 501, a second cleaning pool 504 is arranged on one side of the first cleaning pool 501, the other side of the first cleaning pool 501 is connected with a 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 with an electromagnetic valve 502, and the output port of the electromagnetic valve 502 is connected with the first cleaning pool 501.

[0033] Furthermore, the first cleaning tank 501 is an ultrasonic cleaning tank.

[0034] 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.

[0035] 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 retaining plate 609 .

[0036] Furthermore, when in working state, the shower 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 that is similar to the water flow injected by the shower pipe 503 to the second cleaning tank 504, and the output water flow of the filter 10 can be controlled by the liquid level sensor.

[0037] Furthermore, as the second cleaning pool 504 is injected with water by the shower pipe 503 , excess water flows into the first cleaning pool 501 through the conveying device 6 and is discharged along with the filter 10 .

[0038] See attached Figure 6 and attached Figure 7 The feeding device 6 includes a material guide sleeve 601, a first porous tube 603, and a second porous flushing tube 604. The feeding port of the material 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. A feeding spiral plate 602, a material beating plate 605, a feeding spiral plate 606, and a shaft sleeve 607 are rotatably connected in the material guide sleeve 601. 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 material beating plate 605 is located between the feeding spiral plate 602 and the first porous tube 603. The material beating plate 605 is composed of a plurality of 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.

[0039] The shaft sleeve 607 is located outside the second cleaning tank 504 away from the first cleaning tank 501 , and at least one discharge plate 608 is fixedly connected to the outside of the shaft sleeve 607 , and a water retaining plate 609 is fixedly connected to the end of the guide sleeve 601 .

[0040] 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 602 .

[0041] 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 pipe 604. As the punching plate 605 turns over the plastic crushed objects, the flushing effect of the plastic crushed objects is ensured.

[0042] Furthermore, the water level of the material guiding sleeve 601 is lower than the top of the water baffle 609.

[0043] Furthermore, the guide tube 611 is trumpet-shaped, and the inclined surface facilitates the guidance of the broken plastic objects.

[0044] 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 tube 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 retaining plate 609.

[0045] Refer to the attached Figure 6 One end of the guide sleeve 601 close to the discharge plate 608 is ball-hinged with a guide shaft 610, and 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. A guide pipe 611 is fixedly connected to the outer side of the guide shaft 610, and a water-permeable hole is opened on the guide pipe 611. A plurality of flipping plates 612 are arranged at intervals on the inner side of the guide pipe 611.

[0046] Furthermore, the set 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.

[0047] According to the above structure, in the process of guiding the cleaned plastic crushed objects, the guide sleeve 601 rotates synchronously with the rotation of the guide sleeve 601, and because the hinge between the guide shaft 610 and the guide sleeve 601 is an eccentric hinge, each rotation of the guide tube 611 will cause the plastic crushed objects to vibrate, thereby improving the removal of moisture attached to the surface of the plastic crushed objects.

[0048] See attached Figure 4 and attached Fig.11 The feeding device 2 7 includes a receiving plate 701, which is located on the top of the air-drying bin 2. The granulating bin 1 is rotatably connected to a spiral shaft 704 at a position corresponding to the receiving plate 701. A material guide pipe 2 702 is sleeved on the outer side of the spiral shaft 704. A fan 1 703 is fixedly connected to the end of the material guide pipe 2 702. 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.

[0049] Furthermore, the fan 1 703 can further air-dry the broken plastics in the guide pipe 2 702, and at the same time introduce the accumulated hot and humid air on the top of the granulation bin 1 into the air-drying bin 2 and discharge it to the outside air.

[0050] According to the above structure, the crushed plastics 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 crushed plastics are sent into the second drying chamber 9 through the discharge hole.

[0051] See attached Figure 4 and attached Figures 15 to 16 The second drying chamber 9 includes a collection chamber 901, which is slidably connected to the top side of the granulation bin 1, and the collection chamber 901 is necked from top to bottom. A sealing strip 903 is slidably inserted at the bottom of the punching rod 904, and a feeding hole 906 is provided at the position of the blocking strip 903 corresponding to the feeding hole of the plastic extruder 13. The front and rear sides of the bottom of the collection chamber 901 are fixedly connected with a fan 2 902, and the bottom of the collection chamber 901 is rotatably connected with the punching rod 904, and the side of the punching 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 collection chamber 901 is fixedly connected with a support frame 909, and a screw rod 907 is adapted on the support frame 909, and a spring 908 is arranged between the screw rod 907 and the support frame 909, and the transmission card platform 905 corresponds to the end of the screw rod 907.

[0052] Furthermore, a material guide rod and an electric push rod are provided on the outer side of the material collection chamber 901 for pushing the material collection chamber 901 to slide on the blocking strip 903 .

[0053] 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 collection chamber 901 is full of materials, the collection chamber 901 is dragged toward the clinker port of the plastic extruder 13 under the operation of the electric push rod.

[0054] Furthermore, the feed hole 906 is close to one side of the aggregate chamber 901, and the groove protrudes toward the side of the aggregate chamber 901. By controlling the interlacing of the feed hole 906 and the bottom of the aggregate chamber 901, the size of the feed port for feeding the plastic extruder 13 is controlled to prevent the plastic crushed materials from being fed too quickly and overflowing from the top of the plastic extruder 13.

[0055] Furthermore, a plurality of levers of different lengths are fixedly connected to the surface of the knocking rod 904 .

[0056] Furthermore, the ends of the screw rod 907 and the transmission card platform 905 are provided with mutually engaging protrusions. When the screw rod 907 contacts the transmission card platform 905, the screw rod 907 can drive the transmission card platform 905 to rotate in one direction. Preferably, the contact surface between the screw rod 907 and the transmission card platform 905 is provided with a plurality of wedge blocks with opposite inclined surfaces. Furthermore, a fixedly connected roller screw sleeve is provided at the connection between the support frame 909 and the screw rod 907 .

[0057] According to the above structure, when the collecting chamber 901 moves to the corresponding 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; 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, so as to disrupt the compacted part of the accumulated plastic fragments, and the punching rod 904 is driven to rotate during the feeding process of the plastic extruder 13 to avoid the compaction of the plastic fragments in the collection chamber 901.

[0058] See 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. An air duct 802 is arranged at the air inlet end of the heat dissipation fan 805. The air duct 802 is connected to the outer side of the granulation bin 1. A water guide pipe 804 is connected to one side of the heat dissipation structure 803. A cutter fixing frame 806 is fixedly connected to the output end of the strip making mold 801. A rotating 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 rotating disk 807 and the cutting blade 808 are transmission-connected by a push rod 810. The rotating disk 807, the cutting blade 808 and the push rod 810 form a crank slider component. A particle guide plate 809 is arranged on the outer side of the cutting blade 808.

[0059] Furthermore, the water outlet of the water conduit 804 is connected to the water inlet of the shower pipe 503 .

[0060] 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 with the operation of the fan three 12, and finally discharged from the air drying bin 2 to the external control.

[0061] 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 is heated up as the operation time progresses, thereby further improving the cleaning effect on the broken plastic objects.

[0062] Furthermore, a stepper 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.

[0063] 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 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.

[0064] The working principle of the present invention is: The defective products and scraps generated in the factory production are recycled and fed into the crusher 4 through the feeding port 14; The pulverizer 4 is driven by an external motor to crush the plastic in the pulverizer 4; The crushed plastic is input into the cleaning tank 5 through the feeding device 6. The crushed plastic is pushed into the first cleaning tank 501 under the rotation of the feeding spiral plate 602. The dirt on the surface of the crushed plastic is removed under ultrasonic cleaning and discharged from the through hole 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 crushed plastic in the second porous flushing pipe 604 is flushed by the flushing pipe 503, and the crushed plastic is turned over by the punching plate 605 to achieve the cleaning effect of the crushed plastic. Finally, the crushed plastic is lifted by the discharge plate 608 under the guidance of the feeding spiral plate 606 and transported to the guide pipe 611 at the top of the water retaining plate 609. In the process of guiding the cleaned plastic crushed objects, the guide sleeve 1 601 rotates synchronously with the rotation of the guide sleeve 1 601, and because the hinge between the guide shaft 610 and the guide sleeve 1 601 is an eccentric hinge, each rotation of the guide pipe 611 causes the plastic crushed objects to vibrate, thereby improving the removal of moisture attached to the surface of the plastic crushed objects, and under the guidance of the guide pipe 611, the crushed objects are input into the air drying bin 2; 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 first air-dried 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 slope 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; 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, and then 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 facilitating the workers to carry them.

[0065] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
