Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling technology, and in particular to a recycling device for plastic waste. Background Technology

[0002] With the rapid development of the plastics industry, plastic products are widely used in production and daily life, resulting in a sharp increase in plastic waste. Plastic waste is characterized by its difficulty in degradation and large volume; direct disposal not only causes serious environmental pollution but also leads to a significant waste of resources.

[0003] Some existing recycling devices for plastic waste typically feed the plastic waste directly into the crushing chamber for crushing. However, plastic waste contains metallic impurities. If these impurities are not screened, they can easily cause serious damage to the cutting tools during crushing, or even lead to equipment failure. Furthermore, the waste tends to clump together after crushing, and failing to break it up can result in poor subsequent grading and processing, thus affecting recycling efficiency.

Smaller particles fall through the screen into the second discharge hopper. Simultaneously, the fourth transmission wheel in the conveying assembly is linked to the third transmission wheel via the second transmission belt, transmitting the rotational motion of the rotating rod to the conveying shaft. The rotation of the conveying shaft drives the spiral conveying blades to smoothly push the waste to the discharge pipe for discharge, achieving continuous and stable discharge. Waste that does not meet the standards is discharged from the discharge frame for easy re-crushing.

[0025] The following is in conjunction with the appendix Figure 1 —7. The present invention will be described in further detail.

[0026] This invention discloses a recycling device for plastic waste, including a box 1, which is fixedly installed on the top of a support platform 2. A receiving box 3 is also placed on the support platform 2 at the bottom of the box 1. A metal impurity collection box 6 is installed near the edge of the top of the box 1. A feeding mechanism is installed on the top of the box 1. The feeding mechanism is provided with an adsorption structure for adsorbing metal impurities in the waste and a cleaning structure for cleaning metal impurities. A crushing mechanism is installed inside the box 1. The crushing mechanism is provided with a dispersing component. A screening mechanism is also installed inside the box 1.

[0027] refer to Figure 2 and Figure 3 The feeding mechanism includes a feeding hopper 4 installed on the top of the housing 1, an inclined plate 13 installed on the top of the feeding hopper 4, a vibrating plate 5 installed inside the feeding hopper 4, a vibrating motor installed at the bottom of the vibrating plate 5, springs connected to the bottom of both ends of the vibrating plate 5, and the other end of the springs connected to the top of the mounting plate fixedly connected to the inner wall of the feeding hopper 4. A guide plate is also provided at one end of the feeding hopper 4, and one end of the guide plate is located above the metal impurity collection box 6 installed on the top of the housing 1. The adsorption structure includes a fixed plate 7 installed on the side wall of the feeding hopper 4, an electric telescopic rod 8 fixedly installed at the bottom of the fixed plate 7, a moving plate 9 connected to the output end of the electric telescopic rod 8, symmetrical guide rods 10 installed near the two ends of the bottom of the moving plate 9, one end of the guide rod 10 sliding in the corresponding guide hole opened on the fixed plate 7, and several first motors 11 fixedly installed on the side wall of the moving plate 9, the output end of each first motor 11 passing through the moving plate. The shaft hole on the 9 passes through the corresponding opening on the side wall of the feed hopper 4. The output end of the first motor 11 is also connected to a magnetic shaft 12. The magnetic shaft 12 is located inside the feed hopper 4 and directly below the through slot on the inclined plate 13. More specifically, the driving vibration motor drives the vibrating plate 5 to vibrate, causing the plastic waste on the vibrating plate 5 to vibrate and bounce. At the same time, it drives the first motor 11 installed on one side of the moving plate 9, causing the first motor 11 to drive the magnetic shaft 12 connected to the output shaft to rotate. This causes the magnetic shaft 12 to rotate and adsorb metal impurities in the bouncing plastic waste. The electric telescopic rod 8 installed at the bottom of the fixed plate 7 drives the moving plate 9 to move up and down through the guide rod 10, thereby adjusting the height of the magnetic shaft 12 so that it can adapt to waste layers of different thicknesses, ensuring that metal impurities are fully exposed to the magnetic field range and improving adsorption efficiency.

[0028] refer to Figure 4 and Figure 5The cleaning structure includes several drive shafts 16 installed in shaft holes on both sides of the inner wall of the feed hopper 4. Each drive shaft 16 rotates in an arc-shaped groove on the inner wall of one side of the through groove on the inclined plate 13 at the top of the feed hopper 4. A scraper 17 with a certain tilt angle is also installed on the drive shaft 16. A transmission assembly for adjusting the angle of the scraper 17 is also installed on the other side wall of the feed hopper 4. The transmission assembly includes a second motor 14 installed on a support base on the other side wall of the feed hopper 4. The output shaft of the second motor 14 is connected to one end of one of the drive shafts 16. Two identical first synchronous pulleys 15 are also installed on the output shaft of the second motor 14. A first synchronous belt 18 is sleeved on one of the first synchronous pulleys 15. The other end of the first synchronous belt 18 is sleeved with a second synchronous pulley 19 installed on one end of the other drive shaft 16. A second synchronous belt 18 is sleeved on the other first synchronous pulley 15. The other end of the second synchronous belt 20 is fitted with the third synchronous wheel 21 installed at one end of the remaining drive shaft 16. More specifically, when cleaning the metal impurities adsorbed on the magnetic shaft 12, the electric telescopic rod 8 is driven to raise the moving plate 9 to the top position, so that the magnetic shaft 12 is separated from the waste layer in the feed hopper 4. Then the second motor 14 is started, and through the linkage of the first synchronous wheel 15, the first synchronous belt 18, and the second synchronous belt 20, all drive shafts 16 are driven to rotate synchronously. This causes the scraper 17 installed on it to change angle and adhere to the surface of the magnetic shaft 12. The first motor 11 is driven to drive the magnetic shaft 12 to rotate, so that the inclined edge of the scraper 17 scrapes off the metal impurities adsorbed on the outer wall of the magnetic shaft 12. The impurities fall onto the inclined plate 13 under the action of gravity and slide down the inclined surface into the metal impurity collection box 6, completing the automatic cleaning operation.

[0029] refer to Figure 6The crushing mechanism includes a first crushing roller 22 and a second crushing roller 23 installed inside the housing 1. A shaft at one end of each crushing roller 22 and 23 passes through a shaft hole in one side wall of the housing 1 and is fitted with a first gear 24 and a second gear 25. The shaft at one end of the first crushing roller 22 is also connected to the output end of a third motor 27 mounted on an L-shaped support plate 26 on one side wall of the housing 1. A shaft at the other end of each crushing roller 22 and 23 passes through a shaft hole in the other side wall of the housing 1. A first transmission wheel 28 is also mounted on the shaft at the other end of the first crushing roller 22. The dispersing assembly includes a rotating rod 29 rotatably mounted through shaft holes in the side walls at both ends of the housing 1. One end of the rotating rod 29 passes through a shaft hole in one side wall of the housing 1 and is fitted with a second transmission wheel 30. A first transmission belt 31 is sleeved on the second transmission wheel 30, and the other end of the first transmission belt 31 is connected to the first transmission wheel 30. The rotating rod 29 is fitted with a rotating wheel 28. The other end of the rotating rod 29 passes through the shaft hole on the side wall of the other end of the box 1 and is equipped with a third transmission wheel 33. Several dispersing rods 32 are also installed on the rotating rod 29. Inside the box 1, at the bottom of the dispersing rods 32, a first feeding hopper 34 is also installed. More specifically, when the material enters the box 1, the third motor 27 starts and drives the first crushing roller 22 to rotate. Through the meshing of the first gear 24 and the second gear 25, the second crushing roller 23 is driven to rotate in the opposite direction, thereby crushing the plastic waste. The crushed material falls into the area of ​​the dispersing rods 32. At this time, the first transmission wheel 28 transmits power to the second transmission wheel 30 through the first transmission belt 31, which drives the rotating rod 29 to rotate. This causes the dispersing rods 32 to further disperse the crushed material, preventing the plastic waste from clumping or clogging. This ensures that the material is evenly dispersed and passes smoothly through the first feeding hopper 34 into the subsequent processing stage, improving crushing efficiency and output stability.

[0030] refer to Figure 7The screening mechanism includes a screening frame 35 installed inside the housing 1. A vibrating motor is installed at the bottom of the screening frame 35. One end of the screening frame 35 extends through an opening in the side wall of one end of the housing 1, and a discharge frame is installed at the opening. A second discharge hopper 36 is also installed at the bottom of the screening frame 35. The second discharge hopper 36 is connected to a discharge frame 37 installed on the bottom surface of the housing 1. A conveying assembly is installed inside the discharge frame 37. The conveying assembly includes a conveying shaft 38 installed inside the discharge frame 37. A spiral conveying blade 39 is installed on the conveying shaft 38. One end of the conveying shaft 38 extends through a shaft hole in the side wall of one end of the housing 1 and is equipped with a fourth transmission wheel 40. A second transmission belt 41 is sleeved on the fourth transmission wheel 40. The other end of the second transmission belt 41 is connected to a third transmission wheel 40. The drive wheel 33 is nested together, and the bottom of the feeding frame 37 is connected to the bottom of the box 1 by a discharge pipe 42. More specifically, when the vibrating motor starts, it drives the screening frame 35 to generate high-frequency vibration, so that the crushed plastic waste is graded and screened in the screening frame 35. The waste with the required particle size falls into the second feeding hopper 36 after screening, and then enters the feeding frame 37. At this time, the third drive wheel 33 transmits power to the fourth drive wheel 40 through the second drive belt 41, driving the conveyor shaft 38 to rotate, so that the spiral conveyor blade 39 smoothly pushes the waste to the discharge pipe 42 for discharge, realizing continuous and stable discharge. The waste that does not meet the standard is discharged from the discharge frame for easy re-crushing. The whole process is highly automated, effectively improving the screening accuracy and processing efficiency.

[0031] The implementation principle of a plastic waste recycling device according to an embodiment of the present invention is as follows: In use, plastic waste is fed into the feed hopper 4. A vibrating motor is driven, causing the plastic waste to vibrate and bounce on the vibrating plate 5. Simultaneously, a first motor 11 is driven, causing the magnetic shaft 12 to rotate and adsorb metal impurities in the bouncing plastic waste. An electric telescopic rod 8 drives a moving plate 9 to move up and down via a guide rod 10, thereby adjusting the height of the magnetic shaft 12. This allows the magnetic shaft 12 to adapt to waste layers of different thicknesses, ensuring that metal impurities are fully exposed within the magnetic field's range of action, thus improving efficiency. In terms of adsorption efficiency, when cleaning the metal impurities adsorbed on the magnetic shaft 12, the electric telescopic rod 8 drives the moving plate 9 to rise to the top position. Then, the second motor 14 is started, and through the linkage of the first synchronous pulley 15, the first synchronous belt 18, and the second synchronous belt 20, all the transmission shafts 16 are driven to rotate synchronously. This causes the scraper 17 installed on it to adhere to the surface of the magnetic shaft 12, driving the first motor 11 to rotate the magnetic shaft 12. The inclined edge of the scraper 17 scrapes away the metal impurities adsorbed on the outer wall of the magnetic shaft 12. The impurities fall onto the inclined plate 13 under the action of gravity. The plastic waste slides down the slope into the metal impurity collection box 6. After the impurities are cleaned, the plastic waste continues to be conveyed forward along the vibrating plate 5 into the box 1. The third motor 27 starts, causing the first crushing roller 22 and the second crushing roller 23 to rotate and crush the plastic waste. The crushed material falls into the area of ​​the dispersing rod 32. At this time, the first transmission wheel 28 transmits power to the second transmission wheel 30 through the first transmission belt 31, driving the rotating rod 29 to rotate, so that the dispersing rod 32 can further disperse the crushed material, ensuring that the material is evenly dispersed and smoothly passes through the first discharge hopper 34 into the screening frame 3. 5. Then, the vibration motor is started to drive the screening frame 35 to classify and screen the crushed plastic waste. The waste with the required particle size falls into the second feeding hopper 36 after screening, and then enters the feeding frame 37. At this time, the third transmission wheel 33 transmits power to the fourth transmission wheel 40 through the second transmission belt 41, driving the conveying shaft 38 to rotate, so that the spiral conveying blade 39 smoothly pushes the waste to the discharge pipe 42 for discharge, realizing continuous and stable discharge. The waste that does not meet the standard is discharged from the discharge frame for easy re-crushing. The whole process has a high degree of automation and effectively improves the screening accuracy and processing efficiency.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
