Description

Technical Field

[0001] This invention relates to the field of waste plastic granulation technology, specifically to a self-recycling waste plastic granulation device. Background Technology

[0002] Waste plastic pelleting is the core process for the resource recycling of waste thermoplastic plastics. Through a series of processes including crushing, washing, melt extrusion, water cooling and shaping, pelletizing and screening, scattered and irregularly shaped waste plastic films, plastic bottles, plastic baskets, industrial scraps, etc. are transformed into recycled plastic pellets with uniform size and stable flowability. Virgin plastic pellets have high production costs and high energy consumption, while recycled pellets are cheaper and can be reused in injection molding, blown film, extruded pipes, and plastic container manufacturing, which greatly reduces pollution from plastic waste landfill and incineration. It is a key link in the plastic circular economy. The existing waste plastic pelletizing equipment has a cooling tank equipped with a single pressure roller. However, the single pressure roller and the cooling tank are fixedly installed with no lifting space. The gap between the bottom of the pressure roller and the bottom of the tank is fixed and narrow. Multiple plastic strips after extrusion have to pass under the pressure roller. They can only be stuffed in one by one with great effort. It is not possible to stuff them in at once, and the placement speed is slow. After multiple high-temperature plastic strips enter the water, they are prone to entanglement and stacking. The strips block each other, resulting in insufficient contact with the cooling water, uneven cooling and shaping, and incomplete cooling. In the subsequent pelletizing, the pellets are prone to sticking together and clumping, resulting in poor product quality. Summary of the Invention

[0003] The purpose of this invention is to provide a self-recycling waste plastic granulation device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a self-recycling waste plastic granulation device, comprising a granulator, wherein a feeding device is provided on the top of the granulator, and further comprising: A cooling component includes a cooling tank, the end of which is fixedly connected to the end of a granulator.

[0006] Furthermore, the end of the positioning block away from the pressure rod contacts the inner wall of the cooling pool, the inner wall of the sliding frame contacts the surface of the cooling pool, and two pedals are provided, which are symmetrically arranged with the cooling pool as the center.

[0008] Furthermore, the pelletizing component includes a transmission rod, the end of which is rotatably connected to the inner wall of the cutting frame. A power frame is fixedly connected to the surface of the cutting frame, and a power device is fixedly connected to the surface of the power frame. The end of the transmission rod passes through the cutting frame and extends into the interior of the power frame. A meshing wheel is fixedly connected to the surface of the transmission rod. An inclined plate is fixedly connected to the lower surface of the cutting frame, and a drag-reducing rod is rotatably connected to the lower surface of the inclined plate. A stabilizing block is slidably connected to the inner wall of the chute frame. A cutting blade is fixedly connected to the end of the stabilizing block. A driving rod is fixedly connected to the bottom of the stabilizing block. A sliding hole disc is fixedly connected to the center surface of the driving rod. A driving device is fixedly connected to the inner wall of the cutting frame, and an eccentric push rod disc is fixedly connected to the output end of the driving device. A discharge frame is fixedly connected to the lower surface of the discharge frame.

[0009] Furthermore, the cutting frame is located at the end of the cooling pool away from the granulator and above the cooling pool. There are two transmission rods, which are arranged vertically and the two meshing wheels mesh with each other. The ends of the transmission rods are fixedly connected to the output end of the power device. The end of the inclined plate away from the cutting frame extends to the top of the cooling pool.

[0010] Furthermore, there are two stabilizing blocks, which are symmetrically arranged around the cutting blade, with the surface of the cutting blade in contact with the surface of the discharge rack. The discharge rack is located below the cutting blade, the sliding plate is located below the discharge rack, and the push rod of the eccentric push rod plate extends into the interior of the sliding plate.

[0011] Furthermore, the vibrating screen component includes a synchronizing rod, the top of which is fixedly connected to the bottom of the drive rod, a slide is hinged to the end of the synchronizing rod away from the drive rod, a slider is fixedly connected to the bottom of the screening frame, a material distribution frame is fixedly connected to the bottom of the protective frame, a triangular block is fixedly connected to the bottom of the inner wall of the material distribution frame, and a collection frame is fixedly connected to the lower surface of the material distribution frame.

[0012] Furthermore, there are two synchronizing rods, which are symmetrically arranged around the screening frame. The inner wall of the slide is slidably connected to the surface of the slider. The screening frame is inclined, and the material distribution frame is located at the end of the protective frame away from the cutting frame. The bottom of the inner wall of the screening frame is located above the material distribution frame.

[0013] The present invention has the following beneficial effects: This invention's cooling component uses a cooling tank as a carrier, and is equipped with an upper pressure rod, a lower pressure rod, a pedal, a connecting plate, a rocker arm, an elastic rod, and a sliding frame to form a purely mechanical linkage pressing mechanism. The cooling tank is directly connected to the granulator to achieve immediate water cooling of the extruded strips. The operator can raise the lower pressure rod by stepping on the pedal and using the rocker arm lever to facilitate the insertion of plastic strips. After releasing the pedal, the lower pressure rod automatically falls back, working with the upper pressure rod to separate and limit multiple plastic strips, preventing the strips from tangling and stacking in the cooling tank. The grooves in the pressure rods can separate the strips one by one, ensuring that the plastic strips fully contact the cooling water, resulting in uniform and sufficient cooling and shaping. This eliminates the problems of high-temperature strip sticking and clumping during pellet cutting from the source. The entire transmission system has no water-related electrical components, relying on the mechanical transmission of the elastic rod, sliding frame, and cylindrical rod. It is waterproof and corrosion-resistant, suitable for humid pelleting conditions. The double pedals and connecting plate are synchronized, and the lower pressure rod rises and falls smoothly without jamming. At the same time, the inclined plate extends above the cooling tank, and together with the drag-reducing rod, it smoothly transports the cooled strips to the pelleting station, reducing strip pulling and breakage, and machine shutdown due to blockage.

[0014] The pelletizing component of this invention is connected to the end of the cooling tank via a fixed plate. It integrates feeding and cutting by driving the cutting assembly through upper and lower meshing transmission rods and an eccentric push rod. A power unit drives two sets of meshing transmission rods to rotate in opposite directions at a uniform speed. The plastic strips are stably conveyed by roller clamping, preventing slippage and ensuring consistent pellet length. The drive unit rotates the eccentric push rod disc, converting rotary motion into reciprocating linear motion of the drive rod. Combined with symmetrical sliders on both sides and a chute frame, the cutting blade is guided and limited in both directions, resulting in no deviation or vibration during cutting. The plastic pellets have smooth, burr-free cuts, reducing blade wear. An independent unloading rack is installed below the cutting station, allowing the cut pellets to fall directly to the screening station. Material is transferred in layers without accumulation. The eccentric transmission assembly is located below the unloading rack, isolating plastic debris from cooling water and effectively preventing jamming of the transmission mechanism.

[0015] The vibrating screen component of this invention is fixed to the outside of the cutting frame and linked with the pelletizing drive rod. It achieves automatic particle sorting and self-recovery of residual material by relying on the synchronizing rod, inclined screening frame, material distribution frame, and collecting frame. The screening frame is directly connected to the pelletizing mechanism drive rod through two symmetrical synchronizing rods, reusing the cutting power and eliminating the need for an additional vibrating motor, thus simplifying the overall transmission structure. The synchronizing rod is hinged to the sliding frame and slides in cooperation with the bottom slider of the screening frame. With the reciprocating motion of the cutting blade, the screening frame is driven to vibrate at high frequency and small amplitude. The screening frame can automatically screen materials. Qualified particles pass through the screen and fall into the collecting frame, while sticky and long strips of residual material slide along the inclined surface into the material distribution frame. The triangular blocks inside the material distribution frame prevent material accumulation. The residual material can be directly sent back to the pelletizer for secondary processing, realizing self-recovery of materials. The external protective frame prevents particles from splashing.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The cooling component 3 is based on the cooling pool 10. The carrier, together with the upper pressure rod 11, lower pressure rod 15, pedal 16, connecting plate 13, rocker 18, elastic rod 19, and sliding frame 14, constitutes a purely mechanical linkage pressing mechanism. The cooling pool 10 is directly connected to the granulator 1 to realize the immediate water cooling of the extruded strips. The operator can step on the pedal 16 to lift the lower pressure rod 15 with the help of the rocker 18 lever, which makes it easy to thread the plastic strips. After releasing the pedal 16, the lower pressure rod 15 automatically falls back, and works with the upper pressure rod 11 to separate and limit multiple plastic strips, so as to prevent the strips from tangling and stacking in the cooling pool 10.

A power frame 39 is fixedly connected to the surface of the cutting frame 30, and a power unit 38 is fixedly connected to the surface of the power frame 39. The end of the transmission rod 32 passes through the cutting frame 30 and extends into the interior of the power frame 39. A meshing wheel 40 is fixedly connected to the surface of the transmission rod 32. An inclined plate 34 is fixedly connected to the lower surface of the cutting frame 30, and a drag-reducing rod 35 is rotatably connected to the lower surface of the inclined plate 34.

A sliding hole disc 45 is fixedly connected to the center surface of the drive rod 43. The inner wall of the cutting frame 30 is fixedly connected to the chute frame 36. A drive unit 44 is connected, and an eccentric pusher plate 46 is fixedly connected to the output end of the drive unit 44. A discharge rack 31 is fixedly connected to the lower surface of the discharge rack 33. The pelletizing component 4 is connected to the end of the cooling pool 10 by a fixed plate 37. The cutting component completes the integrated feeding and cutting operation by driving the cutting assembly through the upper and lower meshing transmission rods 32 and the eccentric pusher plate 46. The power unit 38 drives the two sets of meshing transmission rods 32 to rotate in opposite directions at a uniform speed. The plastic strip is stably conveyed by the roller surface clamping, preventing slippage and deviation, and ensuring consistent pellet length. The drive unit 44 drives the eccentric pusher plate 46 to rotate, converting the rotary motion into the reciprocating linear motion of the drive rod 43. With the help of the symmetrical stabilizing blocks 41 on both sides and the slide frame 36, the cutting blade 42 is guided and limited in both directions, so there is no deviation or shaking during cutting.

[0026] The cutting frame 30 is located at the end of the cooling pool 10 away from the granulator 1, and the cutting frame 30 is located above the cooling pool 10. There are two transmission rods 32, which are arranged vertically, and two meshing wheels 40 mesh with each other. The ends of the transmission rods 32 are fixedly connected to the output end of the power device 38. The end of the inclined plate 34 away from the cutting frame 30 extends to the top of the cooling pool 10.

[0027] There are two stabilizing blocks 41, which are symmetrically arranged around the cutting blade 42. The surface of the cutting blade 42 is in contact with the surface of the discharge rack 33. The discharge rack 31 is located below the cutting blade 42, and the sliding hole plate 45 is located below the discharge rack 31. The push rod of the eccentric push rod plate 46 extends into the interior of the sliding hole plate 45.

[0028] The vibrating screen component 5 includes a synchronizing rod 56, the top of which is fixedly connected to the bottom of the drive rod 43. A slide 58 is hinged to the end of the synchronizing rod 56 away from the drive rod 43. A slider 57 is fixedly connected to the bottom of the screening frame 51. A material distribution frame 52 is fixedly connected to the bottom of the protective frame 50. A triangular block 53 is fixedly connected to the bottom of the inner wall of the material distribution frame 52. A collection frame 59 is fixedly connected to the lower surface of the material distribution frame 52. The synchronizing rod 56 is hinged to the slide 58 and slides in cooperation with the slider 57 at the bottom of the screening frame 51. As the cutting blade 42 reciprocates, it drives the screening frame 51 to vibrate at a high frequency and a small amplitude. The screening frame 51 can automatically screen materials. Qualified particles pass through the screen and fall into the collection frame 59. Adhesive and long strips of residual material slide down the inclined surface into the material distribution frame 52. The triangular block 53 inside the material distribution frame 52 prevents material accumulation.

[0029] There are two synchronization rods 56, which are symmetrically arranged with the screening frame 51 as the center. The inner wall of the slide 58 is slidably connected to the surface of the slider 57. The screening frame 51 is inclined. The material distribution frame 52 is located at the end of the protective frame 50 away from the cutting frame 30. The bottom of the inner wall of the screening frame 51 is located above the material distribution frame 52.

[0030] In operation, the processed waste plastic is conveyed to the pelletizer 1 via the feeding device 2. The pelletizer 1 extrudes the waste plastic into strips, which are then pulled into the cooling tank 10 by the operator. This allows the strips to cool quickly before pelletizing, preventing them from sticking together. When the operator places the strips into the cooling tank 10, they press down on the pedal 16. As the pedal 16 moves downwards, it pulls the top of the rocker arm 18 downwards via the connection between the elastic rod 19 and the positioning frame 20. Simultaneously, the bottom of the rocker arm 18 pushes the cylindrical rod 17 upwards. The cylindrical rod 17 moves upwards via the sliding frame 1. 4. The connection with the positioning block 12 pulls the lower pressure rod 15 upward. At this time, the lower pressure rod 15 will move to the top of the cooling pool 10, making it convenient for the operator to pass the strip of waste plastic through the bottom of the lower pressure rod 15 and then through the top of the upper pressure rod 11. After the operator releases the pedal 16, the lower pressure rod 15 will fall into the interior of the cooling pool 10 and press down the strip of waste plastic. The lower pressure rod 15 and the upper pressure rod 11 limit the strip of waste plastic to prevent it from condensing together inside the cooling pool 10. At the same time, the grooves on the surfaces of the upper pressure rod 15 and the lower pressure rod 11 will separate the strip of waste plastic one by one, so that the strip of waste plastic can be cooled quickly. After the strips of waste plastic are passed through the cooling tank 10, the operator places them between two conveyor rods 32. The power unit 38 is then activated, causing the conveyor rods 32 to rotate. The two conveyor rods 32 rotate under the meshing of the meshing wheel 40, thus using the two conveyor rods 32 to transfer the strips of waste plastic to the discharge rack 33. At this time, the drive unit 44 is activated, causing the eccentric pusher disc 46 to rotate. As the eccentric pusher disc 46 rotates, it pushes the pusher rod to rotate inside the sliding plate 45, utilizing the eccentric pusher rod... The disc 46 pushes the sliding disc 45 upward. When the sliding disc 45 moves up and down, it pushes the cutting blade 42 to move through the drive rod 43. When the cutting blade 42 moves up and down, it cuts the strip of waste plastic into granules. When the cutting blade 42 moves, it drives the stabilizing block 41 to slide inside the slide frame 36. The stabilizing block 41 is used to improve the stability of the cutting blade 42 during operation. A drag-reducing rod 35 is provided on the lower surface of the inclined plate 34 to support the strip of waste plastic and improve the stability of the strip of waste plastic feeding operation. After granulation, the waste plastic slides down the unloading rack 31 into the screening rack 51. When the drive rod 43 moves up and down, it pulls the synchronization rod 56 to move. When the synchronization rod 56 moves, it pushes the end of the screening rack 51 to shake up and down through the slide 58. When the screening rack 51 shakes, it screens the granulated waste plastic, so that qualified waste plastic falls into the collection rack 59, while unqualified waste plastic slides into the distribution rack 52 for reprocessing. The synchronization rod 56 and the slide 58 are hinged, and the slide 58 and the slider 57 are slidably connected. When the synchronization rod 56 moves up and down, it pushes the slide 58 to slide on the surface of the slider 57 to avoid jamming.
