Therefore, it is very necessary to design a cleaning device and method for waste plastic particles produced by PVC plastic particles. Summary of the invention

[0004] The object of the present invention is to provide a device and method for cleaning waste plastic particles produced from PVC plastic particles, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for cleaning waste plastic particles in the production of PVC plastic particles, comprising a support frame, both sides of the support frame are fixedly connected with side guard plates, the inner bottom surface of the support frame is fixedly connected with a drainage trough, a water pool is arranged above the drainage trough, a recovery and cleaning mechanism is arranged above the water pool, a water filtering mechanism is arranged behind the recovery and cleaning mechanism, a feeding mechanism is arranged behind the water filtering mechanism, a conveyor belt is installed on the top of the water pool, two inner guard plates are fixedly connected to the inner wall at the rear end of the support frame, the water pool is fixedly connected to the support frame, and the inner guard plates are vertically centered with respect to the front of the support frame.

A rotating shaft rod is fixedly connected to the axis center of the crank handle. When the rotating shaft rod connected to the output shaft of the external motor drives the crank handle to rotate, the end of the rotating shaft rod away from the motor rotates to drive the crank handle to rotate, so that the linkage rod connected to the crank handle pushes the piercing rod slide plate to slide along the slide plate rod. When the piercing rod slide plate slides, the pool inner plate connected to the bottom surface of the piercing rod slide plate drives the through-connecting plate to move. Since the inner bottom surface of the pool inner plate is inclined and the pool plate is inclined, the through-connecting plate moves with the pool inner plate, and the through-connecting plate makes the brush block strip stick to the brush block under the action of gravity. The inclined pool plate slides together, and as the brush block moves, the brush block contacts and rubs with the plastic arc strips through the side cotton brush strips, and the plastic particles that slide along the inclined pool plate to between the plastic arc strips are squeezed by the cotton brush strips to the side of the plastic arc strips for friction, and the surface attachments of the recycled plastic particles are cleaned, and the cleaned plastic particles roll along the top surface of the inclined pool plate through the plastic arc strips to the rear end of the pool trough for recycling. The reciprocating motion of the brush block makes the cotton brush strips and the plastic arc strips move relative to each other, so that the plastic particles that fall between the cotton brush strips and the plastic arc strips are washed away by friction and water immersion to remove the dust and attachments of the plastic particles, thereby improving the cleaning effect of the plastic particles and improving the efficiency of plastic cleaning and recycling.

[0006] According to the above technical solution, the water filtering mechanism includes a roller, the roller is fixedly connected to the outer surface of the rotating shaft rod, the outer surface of the roller is fixedly connected with four pushing flaps, each side of the pushing flap is slidably connected with an extended leakage plate, the left and right sides of the extended leakage plate are fixedly connected with side strips, the side of the extended leakage plate away from the pushing flap is fixedly connected with a pushing plate, the side of the pushing plate is slidably connected with two spring connecting rods, the rear end top surface of the water pool trough is fixedly connected with a horizontal slide groove, the inner side of the horizontal slide groove is slidably connected with a slide groove block, and the slide groove The block is fixedly connected with a bent push rod on one side away from the pushing material flip plate, and the bent push rod is slidably connected with a vertical slide groove on one end away from the slide groove block, and the vertical slide groove is slidably connected with a material guide leakage groove on the side away from the bent push rod. A spring is arranged on the outer side of the spring connecting rod, and the two ends of the spring are respectively fixedly connected to the pushing plate and the roller. A spring is arranged on the side of the slide groove block, and the two ends of the spring are respectively fixedly connected to the slide groove block and the horizontal slide groove. The rotation of the rotating shaft rod will drive the connected roller to rotate, so that the roller will flip the extended leakage plate connected to the pushing material flip plate through rotation, and the extended leakage plate will be flipped The plastic particles cleaned on the inclined pool plate are gathered in a clockwise direction. At this time, the extended leak plate pushes the push plate through the spring force on the outside of the spring connecting rod, so that the extended leak plate connected to the push plate extends. As the roller rotates, the extended leak plate adheres to the arc-shaped inner wall at the rear end of the water tank and transports the gathered plastic particles upward until the edge of the extended leak plate is no longer bound by the inner wall of the water tank. The extended leak plate releases the elastic force through the push plate under the action of the spring outside the spring connecting rod, so that the plastic particles on the extended leak plate are pushed into the guide leak groove through the push plate, thereby using the extended leak plate to flip and transfer the cleaned plastic particles. The plastic particles are scooped out and the water is allowed to leak from the side of the extended leak plate into the water tank, which plays a role in separating the plastic particles and water. At the same time, the rotation of the crank handle will squeeze the bent push rod to be stressed, so that the bent push rod will push the slide block to slide along the side of the horizontal slide, so that the end of the slide block pushes the vertical slide to be stressed, so that the guide leak slot is flipped, and the plastic particles on the guide leak slot are tilted and rolled, and the water on the plastic particles is leaked into the water tank through the guide leak slot. The reciprocating flipping of the guide leak slot drives the plastic on the guide leak slot to flip, which improves the drainage effect of the plastic particles and facilitates rapid dehydration.

[0007] The discharging mechanism comprises a discharging end shell, the discharging end shell is fixedly connected to the inner wall of the inner guard plate, the inner wall of the discharging end shell is rotatably connected to the roller, the surface of the roller is slidably connected to the discharging flap, the right side surface of the roller is fixedly connected to the vibration convex ring, and a plurality of thin rod sliding grooves are opened on the right side edge of the roller, each of the inner wall of the thin rod sliding groove is slidably connected to a thin sliding rod, the outer surface of the thin sliding rod is fixedly connected to a vibration spring piece, and the rear end of the discharging end shell is fixedly connected to a discharging port, and one end of the thin sliding rod away from the vibration spring piece is fixedly connected to the discharging flap. When the material enters the interior of the discharging end shell through the material guiding leakage groove, when the drum rotates, the connected discharging flap is driven to rotate by the rotation of the drum, so that the discharging flap rotates, and the plastic particles entering the interior of the discharging end shell from the material guiding leakage groove will be pushed by the flipping discharging flap, and when the discharging flap rotates to the highest point, the plastic particles in the discharging flap will move from the discharging flap under the action of gravity. When the plastic particles on the unloading flap are aligned with the discharging port, the discharging port will be transferred out from the discharging port along the inclined unloading flap, which is convenient for the recovery and collection of the plastic particles at the discharging port. At the same time, when the drum rotates, the vibrating convex ring also rotates with the drum, and the vibration shrapnel is squeezed by the vibrating convex ring to move, so that the fine sliding rod connected to the vibrating convex ring drives the unloading flap to slide away from the drum, thereby making the unloading flap move, and the reciprocating motion of the unloading flap generates shaking, so that the irregular plastic particles on the unloading flap are shaken out when discharging through the discharging port, and the plastic particles on the unloading flap are completely transferred out by shaking, so as to avoid the plastic particles from remaining on the unloading flap, thereby improving the transfer effect of the plastic particles. In addition, when the guide trough flips around the bottom surface of the discharge end shell, the flipping of the guide trough will touch and knock the discharge end shell, thereby making the discharge end shell vibrate as a whole, and further preventing the blockage caused by the retention of plastic particles in the guide trough part of the discharge end shell through vibration.

[0008] A method for using a device for cleaning waste plastic particles produced from PVC plastic particles, comprising the following steps:

[0009] S1: When the external motor drives the crank handle to rotate through the rotating shaft rod connected to the output shaft, the end of the rotating shaft rod away from the motor rotates to drive the crank handle to rotate, so that the linkage rod connected to the crank handle pushes the rod-penetrating slide plate to slide along the slide rod, and the through-link plate is driven to move through the pool inner plate connected to the bottom surface of the rod-penetrating slide plate. When the through-link plate moves with the pool inner plate, the through-link plate causes the brush block strip to slide against the inclined pool plate under the action of gravity;

[0010] S2: As the brush block moves, the brush block contacts and rubs with the plastic arc strips through the side cotton brush strips, and the plastic particles that slide along the inclined pool plate to the plastic arc strips are squeezed by the cotton brush strips to the side of the plastic arc strips for friction, so that the attached substances on the surface of the recycled plastic particles are cleaned, and the cleaned plastic particles pass through the plastic arc strips and roll along the top surface of the inclined pool plate to the rear end of the pool tank for recycling;

[0011] S3: The reciprocating motion of the brush block makes the cotton brush bar and the plastic arc bar move relative to each other, so that the plastic particles falling between the cotton brush bar and the plastic arc bar are washed away by friction and water immersion to remove the dust and attachments of the plastic particles, thereby improving the cleaning effect of the plastic particles and improving the efficiency of plastic cleaning and recycling;

[0012] S4: The rotation of the shaft rod drives the connected roller to rotate, so that the roller turns over the extended leak plate connected to the push plate, and the plastic particles washed on the inclined pool plate are gathered in a clockwise direction by turning over the extended leak plate. At this time, the extended leak plate pushes the push plate through the spring force on the outer side of the spring connecting rod, so that the extended leak plate connected to the push plate extends;

[0013] S5: As the roller rotates, the extended leak plate transports the gathered plastic particles upward in accordance with the arc-shaped inner wall at the rear end of the water tank until the edge of the extended leak plate is no longer bound by the inner wall of the water tank. The extended leak plate releases elastic force through the push plate under the action of the outer spring of the spring connecting rod, so that the plastic particles on the extended leak plate are pushed into the guide leak trough through the push plate, so that the cleaned plastic particles are fished out by turning the extended leak plate, and water is allowed to leak from the side of the extended leak plate into the water tank;

[0014] S6: The rotation of the crank handle will squeeze the bending push rod to be stressed, so that the bending push rod pushes the chute block to slide along the side of the horizontal chute after being stressed, so that the end of the chute block pushes the vertical chute to be stressed, so that the material guide chute flips, and the plastic particles on the material guide chute roll tiltedly, and the water on the plastic particles leaks into the water trough through the material guide chute. The reciprocating flipping of the material guide chute drives the plastic on the material guide chute to flip, which improves the drainage effect of the plastic particles and facilitates rapid dehydration;

[0015] S7: When the material enters the discharge end shell through the guide slot, the drum rotates, driving the connected discharge flap to rotate, so that the discharge flap rotates, and the plastic particles entering the discharge end shell from the guide slot will be pushed by the flipping discharge flap. When the discharge flap rotates to the highest point, the plastic particles in the discharge flap will move from the discharge flap to another discharge flap under the action of gravity. After the plastic particles on the discharge flap are aligned with the discharge port, the discharge port will be transferred out from the discharge port along the inclined discharge flap, so as to facilitate the recovery and collection of the plastic particles at the discharge port;

[0016] S8: When the drum rotates, the vibrating convex ring also rotates with the drum, and the vibrating shrapnel is squeezed by the vibrating convex ring to move, so that the thin sliding rod connected to the vibrating convex ring drives the unloading flap to slide away from the drum, thereby moving the unloading flap. The reciprocating motion of the unloading flap generates shaking, so that the irregular plastic particles on the unloading flap are shaken out when discharging through the discharging port, and the plastic particles on the unloading flap are completely transferred out by shaking.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] The present invention is provided with a crank handle, a linkage rod, a fixing seat, a rod-penetrating slide plate, a slide plate rod, a pool inner plate, a through-connecting plate, a brush block strip, a cotton brush strip, a plastic arc strip, and an inclined pool plate. The cleaned plastic particles are rolled along the top surface of the inclined pool plate through the plastic arc strips to the rear end of the water pool trough for recycling. The reciprocating motion of the brush block strip allows the cotton brush strip and the plastic arc strip to move relative to each other, so that the plastic particles falling between the cotton brush strip and the plastic arc strip are washed away by friction and water immersion to remove dust and attachments of the plastic particles, thereby improving the cleaning effect of the plastic particles and improving the efficiency of plastic cleaning and recycling.

[0019] The present invention is provided with rollers, a material pushing flap, a spring connecting rod, a material pushing plate, an extended leakage plate, side strips, a bent push rod, a chute block, a horizontal chute, a vertical chute, and a material guiding leakage chute. The extended leakage plate is turned over to fish out the cleaned plastic particles, and water is allowed to leak from the side of the extended leakage plate to the water tank, thereby separating the plastic particles from the water. At the same time, the rotation of the crank handle will squeeze the bent push rod to be stressed, so that the bent push rod pushes the chute block to slide along the side of the horizontal chute after being stressed, so that the end of the chute block pushes the vertical chute to be stressed, so that the material guiding leakage chute is turned over, the plastic particles on the material guiding leakage chute are tilted and rolled, and the water on the plastic particles is leaked into the water tank through the material guiding leakage chute, and the reciprocating flipping of the material guiding leakage chute drives the plastic on the material guiding leakage chute to flip, thereby improving the drainage effect of the plastic particles, and facilitating and rapid dehydration.

[0020] The present invention is provided with a discharge end shell, a roller, a discharge flap, a vibrating convex ring, a thin rod slide groove, a thin slide rod, a vibrating spring piece, and a discharge port. The reciprocating motion of the discharge flap generates shaking, so that irregular plastic particles on the discharge flap are shaken out when discharged through the discharge port, and the plastic particles on the discharge flap are completely transferred out through the shaking, so that it is avoided that the plastic particles remain on the discharge flap, and the transfer effect of the plastic particles is improved. In addition, when the guide leakage trough turns over around the bottom surface of the discharge end shell, the turning of the guide leakage trough will touch and knock the discharge end shell, so that the discharge end shell vibrates as a whole, and the vibration further prevents the blockage caused by the retention of plastic particles in the guide leakage trough part of the discharge end shell.

A slide block 68 is slidably connected to the inner side of the horizontal slide 69. A bent push rod 67 is fixedly connected to the side of the slide block 68 away from the pushing flap 62. The end of the bent push rod 67 away from the slide block 68 is slidably connected to a vertical slide 610.

The extended leak plate 65 is turned over to fish out the cleaned plastic particles, and the water is allowed to leak from the side of the extended leak plate 65 to the sink 4, thereby separating the plastic particles and the water. At the same time, the rotation of the crank handle 51 will squeeze the bent push rod 67 to be stressed, so that the bent push rod 67 pushes the slide block 68 to slide along the side of the horizontal slide 69 after being stressed, so that the end of the slide block 68 pushes the vertical slide 610 to be stressed, so that the guide leak groove 611 is flipped, the plastic particles on the guide leak groove 611 are tilted and rolled, and the water on the plastic particles is leaked into the water leakage groove 3 through the guide leak groove 611. The reciprocating flipping of the guide leak groove 611 drives the plastic on the guide leak groove 611 to flip, thereby improving the drainage effect of the plastic particles, which is convenient and quick to dehydrate.

[0037] The unloading mechanism 7 includes an unloading end shell 71, which is fixedly connected to the inner wall of the inner guard plate 9, and the inner wall of the unloading end shell 71 is rotatably connected to a roller 72, and the surface of the roller 72 is slidably connected to a unloading flap 73, and the right side of the roller 72 is fixedly connected to a vibration convex ring 74, and a plurality of thin rod sliding grooves 75 are provided at the right edge of the roller 72, and the inner wall of each thin rod sliding groove 75 is slidably connected to a thin sliding rod 76, and the outer surface of the thin sliding rod 76 is fixedly connected to a vibrating spring piece 77, and the rear end of the unloading end shell 71 is fixedly connected to a discharge port 78, and the end of the thin sliding rod 76 away from the vibrating spring piece 77 is fixed to the unloading flap 73 The fixed connection generates shaking through the reciprocating motion of the unloading flap 73, so that the irregular plastic particles on the unloading flap 73 are shaken out when discharging through the discharging port 78, and the plastic particles on the unloading flap 73 are completely transferred out through the shaking, so as to avoid the plastic particles from remaining on the unloading flap 73, thereby improving the transfer effect of the plastic particles. In addition, when the material guiding trough 611 flips around the bottom surface of the discharge end shell 71, the flipping of the material guiding trough 611 will touch and knock the discharge end shell 71, thereby making the discharge end shell 71 vibrate as a whole, and further prevent the blockage caused by the retention of plastic particles in the material guiding trough 611 of the discharge end shell 71 through vibration.

[0038] Working principle: When the external motor drives the crank handle 51 to rotate through the rotating shaft rod 10 connected to the output shaft, the end of the rotating shaft rod 10 away from the motor rotates to drive the crank handle 51 to rotate, so that the linkage rod 52 connected to the crank handle 51 pushes the rod-penetrating slide plate 54 to slide along the slide plate rod 55. When the rod-penetrating slide plate 54 slides, the pool inner plate 56 connected to the bottom surface of the rod-penetrating slide plate 54 drives the through-connecting plate 57 to move. Since the bottom surface of the pool inner plate 56 is inclined and the pool plate 511 is inclined, when the through-connecting plate 57 moves with the pool inner plate 56, the through-connecting plate 57 makes the brush block strip 58 slide in contact with the inclined inclined pool plate 511 under the action of gravity. As the brush block strip 58 moves, the brush block strip 58 and the plastic brush bar 59 are connected to the side cotton brush strip 59. The plastic arc strips 510 are in contact and rubbed with the material arc strips 510, and the plastic particles that slide down the inclined pool plate 511 to between the plastic arc strips 510 are squeezed to the side of the plastic arc strips 510 for friction through the cotton brush strips 59, so that the attachments on the surface of the recycled plastic particles are cleaned, and the cleaned plastic particles pass through the plastic arc strips 510 and roll along the top surface of the inclined pool plate 511 to the rear end of the pool trough 4 for recycling. The brush block strips 58 reciprocate to make the cotton brush strips 59 and the plastic arc strips 510 move relative to each other, so that the plastic particles that fall between the cotton brush strips 59 and the plastic arc strips 510 are washed away by friction and water immersion to remove the dust and attachments of the plastic particles, thereby improving the cleaning effect of the plastic particles and improving the efficiency of plastic cleaning and recycling.

[0039] The rotation of the rotating shaft rod 10 will drive the connected roller 61 to rotate, so that the roller 61 can flip the extended leak plate 65 connected to the pushing flap 62 through rotation, and the plastic particles cleaned on the inclined pool plate 511 are gathered in a clockwise direction through the flipping of the extended leak plate 65. At this time, the extended leak plate 65 pushes the pushing plate 64 through the spring elastic force on the outer side of the spring connecting rod 63, so that the extended leak plate 65 connected to the pushing plate 64 extends. As the roller 61 rotates, the extended leak plate 65 conveys the gathered plastic particles upward in accordance with the arc-shaped inner wall at the rear end of the water tank 4 until the edge of the extended leak plate 65 is no longer bound by the inner wall of the water tank 4. The extended leak plate 65 releases the elastic force through the pushing plate 64 under the action of the spring outside the spring connecting rod 63, so that the plastic particles on the extended leak plate 65 pass through the pushing plate The plate 64 is pushed into the material guiding trough 611, so that the extended trough 65 is turned over to fish out the cleaned plastic particles, and the water is allowed to leak from the side of the extended trough 65 to the water tank 4, so as to separate the plastic particles from the water. At the same time, the rotation of the crank handle 51 will squeeze the bent push rod 67 to be stressed, so that the bent push rod 67 pushes the slide block 68 to slide along the side of the horizontal slide 69 after being stressed, so that the end of the slide block 68 pushes the vertical slide 610 to be stressed, so that the material guiding trough 611 is flipped, and the plastic particles on the material guiding trough 611 are tilted and rolled, and the water on the plastic particles is leaked into the water tank 3 through the material guiding trough 611, and the plastic on the material guiding trough 611 is flipped by the reciprocating flipping of the material guiding trough 611 to enhance the drainage effect of the plastic particles, so as to facilitate and quickly dehydrate.

[0040] When the material enters the discharge end shell 71 through the material guide slot 611, when the roller 72 rotates, the connected material discharge flap 73 is driven to rotate by the rotation of the roller 72, so that the material discharge flap 73 rotates, and the plastic particles entering the discharge end shell 71 from the material guide slot 611 will be pushed by the flipping material discharge flap 73. When the material discharge flap 73 rotates to the highest point, the plastic particles in the material discharge flap 73 will move from the material discharge flap 73 to another material discharge flap 73 under the action of gravity. After the plastic particles on the material discharge flap 73 are aligned with the discharge port 78, the discharge port 78 will be transferred out from the discharge port 78 along the inclined material discharge flap 73, so as to facilitate the recovery and collection of the plastic particles at the discharge port 78. At the same time, when the roller 72 rotates, the vibrating convex ring 74 also rotates with the roller 72 The rotating ring 74 squeezes the vibration spring piece 77 to move, so that the thin sliding rod 76 connected to the vibration ring 74 drives the unloading flap 73 to slide away from the roller 72, thereby allowing the unloading flap 73 to move, and the reciprocating motion of the unloading flap 73 generates shaking, so that the irregular plastic particles on the unloading flap 73 are shaken out when discharging through the discharge port 78, and the plastic particles on the unloading flap 73 are completely transferred out by shaking, so as to avoid the plastic particles from remaining on the unloading flap 73, thereby improving the transfer effect of the plastic particles. In addition, when the material guiding trough 611 flips around the bottom surface of the discharge end shell 71, the flipping of the material guiding trough 611 will touch and knock the discharge end shell 71, thereby causing the discharge end shell 71 to vibrate as a whole, and further preventing the blockage caused by the retention of plastic particles in the material guiding trough 611 of the discharge end shell 71 through vibration.

[0041] A method for using a device for cleaning waste plastic particles produced from PVC plastic particles, comprising the following steps:

[0042] S1: When the external motor drives the crank handle 51 to rotate through the rotating shaft rod 10 connected to the output shaft, the end of the rotating shaft rod 10 away from the motor rotates to drive the crank handle 51 to rotate, so that the linkage rod 52 connected to the crank handle 51 pushes the rod-penetrating slide plate 54 to slide along the slide plate rod 55, and drives the through-connecting plate 57 to move through the pool inner plate 56 connected to the bottom surface of the rod-penetrating slide plate 54. When the through-connecting plate 57 moves with the pool inner plate 56, the through-connecting plate 57 causes the brush block strip 58 to slide against the inclined pool plate 511 under the action of gravity;

[0043] S2: As the brush block 58 moves, the brush block 58 contacts and rubs with the plastic arc strip 510 through the side cotton brush strip 59, and the plastic particles that slide along the inclined pool plate 511 to the plastic arc strip 510 are squeezed by the cotton brush strip 59 to the side of the plastic arc strip 510 for friction, so that the attached substances on the surface of the recycled plastic particles are cleaned, and the cleaned plastic particles pass through the plastic arc strip 510 and roll along the top surface of the inclined pool plate 511 to the rear end of the pool tank 4 for recycling;

[0044] S3: The brush block strip 58 reciprocates to make the cotton brush strip 59 and the plastic arc strip 510 move relative to each other, so that the plastic particles falling between the cotton brush strip 59 and the plastic arc strip 510 are washed away by friction and water immersion to remove dust and attachments from the plastic particles, thereby improving the cleaning effect of the plastic particles and improving the efficiency of plastic cleaning and recycling;

[0045] S4: The rotation of the shaft rod 10 drives the connected roller 61 to rotate, so that the roller 61 turns over the extended leak plate 65 connected to the pusher flap 62 by rotating, and the plastic particles cleaned on the inclined pool plate 511 are gathered in a clockwise direction by turning over the extended leak plate 65. At this time, the extended leak plate 65 pushes the pusher plate 64 through the spring elastic force on the outer side of the spring connecting rod 63, so that the extended leak plate 65 connected to the pusher plate 64 extends;

[0046] S5: As the roller 61 rotates, the extended leak plate 65 conveys the gathered plastic particles upward along the arc-shaped inner wall at the rear end of the water tank 4 until the edge of the extended leak plate 65 is no longer bound by the inner wall of the water tank 4. The extended leak plate 65 releases elastic force through the push plate 64 under the action of the outer spring of the spring connecting rod 63, so that the plastic particles on the extended leak plate 65 are pushed into the guide leak groove 611 through the push plate 64, so that the cleaned plastic particles are fished out by turning the extended leak plate 65, and water is allowed to leak from the side of the extended leak plate 65 down into the water tank 4;

[0047] S6: The crank handle 51 rotates to squeeze the bending push rod 67 to be stressed, so that the bending push rod 67 pushes the chute block 68 to slide along the side of the horizontal chute 69, so that the end of the chute block 68 pushes the vertical chute 610 to be stressed, so that the material guide chute 611 flips, so that the plastic particles on the material guide chute 611 roll obliquely, and the water on the plastic particles leaks into the water leakage trough 3 through the material guide chute 611. The reciprocating flipping of the material guide chute 611 drives the plastic on the material guide chute 611 to flip, thereby improving the drainage effect of the plastic particles and facilitating rapid dehydration.

[0048] S7: When the material enters the discharge end shell 71 through the material guide slot 611, the roller 72 rotates, and the connected material discharge flap 73 is driven to rotate by the rotation of the roller 72, so that the material discharge flap 73 rotates, and the plastic particles entering the discharge end shell 71 from the material guide slot 611 will be pushed by the flipping material discharge flap 73. When the material discharge flap 73 rotates to the highest point, the plastic particles in the material discharge flap 73 will move from the material discharge flap 73 to another material discharge flap 73 under the action of gravity. After the plastic particles on the material discharge flap 73 are aligned with the discharge port 78, the discharge port 78 will be transferred out from the discharge port 78 along the inclined material discharge flap 73, so that the plastic particles at the discharge port 78 can be recycled and collected conveniently;

[0049] S8: When the roller 72 rotates, the vibrating convex ring 74 also rotates with the roller 72, and the vibrating shrapnel 77 is squeezed by the vibrating convex ring 74 to move, so that the thin sliding rod 76 connected to the vibrating convex ring 74 drives the unloading flap 73 to slide away from the roller 72, thereby allowing the unloading flap 73 to move, and the reciprocating motion of the unloading flap 73 generates shaking, so that the irregular plastic particles on the unloading flap 73 are shaken out when discharging through the discharging port 78, and the plastic particles on the unloading flap 73 are completely transferred out by shaking.
