Description

Technical Field

[0001] This utility model relates to the field of recycling devices, and in particular to a plastic pellet recycling device. Background Technology

[0002] Waste plastic treatment is a crucial link in environmental protection and resource recycling. Traditional treatment methods include landfill, incineration, and direct recycling. Landfill occupies a large amount of land resources, and plastics are not easily degraded, causing long-term environmental pollution. Incineration may release harmful gases, affecting air quality. Physical recycling technology mainly uses mechanical means to separate, clean, crush, melt, and granulate waste plastics to restore their original properties or prepare new plastic products.

[0003] Existing plastic granule recycling devices typically use a storage box to collect plastic granules, heat-melt the plastic, extrude it through extrusion, and then cut it into granules. Some plastic granule recycling devices use a fixed-opening receiving port, aligning the receiving port at the top of the recycling device with the granulation port of the plastic granules to collect the raw materials.

[0004] On the one hand, the existing method of directly receiving raw granules in the storage box cannot cool the hot-melted raw granules and cannot simultaneously screen raw granules of different sizes. On the other hand, the existing fixed opening of the material inlet requires repeated adjustment of the recycling device or granulation device and cannot quickly and manually change the receiving angle of the material inlet. Therefore, a plastic raw granule recycling device is proposed to solve the above problems. Utility Model Content

A scraper is fixedly connected to the outer wall of the transmission belt. A screening plate is fixedly connected to the bottom of the inner wall of the base. A receiving box is slidably connected to the bottom of the inner wall of the base.

It is equipped with a valve port for easy manual pouring or suction with the help of external tools. A rotating shaft 8 is slidably connected through the top right side of the base 1. The rotating shaft 8 is used to provide the center point for the rotation of the receiving plate 9. The rotating shaft 8 is driven to rotate by the limiting rod 18, thereby driving the receiving plate 9 to rotate. The receiving plate 9 is fixedly connected to the top of the outer wall of the rotating shaft 8. The receiving plate 9 is used to dock with the granulation device to receive raw particles. A screening component is set in the middle of the inner wall of the base 1. The output shaft of motor 1 2 is slidably connected through the top inner wall of the base 1. The bottom of the outer wall of the conveyor belt 3 is slidably connected to the inner wall of the base 1. The bottom of the outer wall of the receiving plate 9 is slidably connected to the top of the outer wall of the base 1. The outer wall of the rotating shaft 8 is slidably connected through the inner wall of the limiting base 20.

[0033] Reference Figures 2-4The screening component includes a second motor 10, which is existing technology and will not be described in detail. It drives the transmission shaft 11 to move the scraper 13 and push the plastic granules. The second motor 10 is fixedly connected to the outer wall of the back of the base 1. The output shaft of the second motor 10 is fixedly connected to the transmission shaft 11. Two sets of transmission shafts 11 are provided, and the two sets of transmission shafts 11 are connected by a transmission belt 12. The transmission belt 12 drives the scraper 13 to repeatedly push the plastic granules around the transmission shaft 11. The scraper 13 is fixedly connected to the outer wall of the transmission belt 12. The scraper 13 can be made of plastic to prevent harder materials from squeezing and damaging the plastic granules. The plastic granules are pushed through the screening plate 14. The screening plate 14 is fixedly connected to the bottom of the inner wall of the base 1. The screening plate 14 is provided with two different sizes of holes for screening plastic granules of different sizes. Together with the receiving box 15, it achieves the effect of three-stage screening. The receiving box 15 is slidably connected to the bottom of the inner wall of the base 1. The receiving box 15 is provided with three sections for receiving three different sizes of plastic granules.

[0034] Reference Figure 3-Figure 5 A steering base 16 is fixedly connected to the bottom of the outer wall of the rotating shaft 8. The steering base 16 provides an extension fixing point for the limiting spring 17. A limiting rod 18 is elastically connected to the bottom of the outer wall of the steering base 16 through the limiting spring 17. The limiting rod 18 is used to manually press down externally, thereby causing the limiting block 19 to disengage from the limiting groove 21 and release the limiting. A limiting block 19 is fixedly connected to the top of the outer wall of the limiting rod 18. The limiting block 19 is set as a rectangular block and is used to engage with the limiting groove 21 to fix the rotation angle of the rotating shaft 8. A limiting base 20 is fixedly connected to the top right side of the outer wall of the base 1. The limiting base 20 is used to keep the rotating shaft 8 perpendicular to its rotation and to prevent the rotating shaft 8 from tilting under force, which would cause the receiving plate 9 to deviate. A limiting groove 21 is provided at the bottom of the outer wall of the base 20. Several sets of limiting grooves 21 are provided for multiple locking limiting blocks 19 to fix the angle of the receiving plate 9. One end of the limiting spring 17 is fixedly connected to the bottom of the outer wall of the steering base 16, and the other end of the limiting spring 17 is fixedly connected to the top of the outer wall of the limiting rod 18. Through the opposing pressing force between the limiting spring 17 and the steering base 16, the limiting block 19 is always locked on the inner wall of the limiting groove 21 without being affected by external force. The outer wall end of the limiting rod 18 is hinged to the bottom of the outer wall of the rotating shaft 8, and the outer wall end of the limiting block 19 is locked on the inner wall of the limiting groove 21. The bottom of the outer wall of the steering base 16 is slidably connected to the top of the outer wall of the limiting base 20.

[0035] Working principle: When receiving and screening raw granules, the receiving plate 9 is aligned with the granulation device. The raw granules are extruded by the granulation device and enter the top of the base 1. Then, motor 2 is turned on to drive the conveyor belt 3. The conveyor belt 3 drives the raw granules to cool rapidly in the water tank at the top of the base 1. The granules are continuously conveyed and fall from the slide 4 to the drainage plate 6. At the same time, the blower 5 blows air to accelerate the water removal of the raw granules. Then, the raw granules slide from the drainage plate 6 onto the transmission belt 12. Then, motor 10 is turned on to drive the transmission belt 12 to rotate. The transmission belt 12 drives the scraper 13 to make a back-shaped motion along the outer wall of the transmission belt 12. The scraper 13 repeatedly pushes the raw granules to move on the top of the screening plate 14, so that raw granules of different sizes fall into the receiving box 15. This realizes automated receiving, cooling and screening operations and improves recycling efficiency.

[0036] When it is necessary to move the base 1 to align with the pelletizing device, the limiting rod 18 is manually pressed down to drive the limiting block 19 to disengage from the limiting groove 21 and release the limitation. Then, the limiting rod 18 is rotated to drive the rotating shaft 8 to rotate, which in turn drives the receiving plate 9 to rotate to the docking position. After releasing the limiting rod 18, the limiting block 19 is bounced back to the inner wall of the corresponding limiting groove 21 by the limiting spring 17 and locked in place. This allows for quick manual adjustment of the receiving position, saving the manpower and resources of repeatedly moving the base 1 and improving recycling efficiency.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
