Description

Technical Field

[0001] This invention relates to a waste recycling device, specifically a waste recycling device for the production of PVC Christmas tree leaves. Background Technology

[0002] The production of PVC Christmas tree leaves generates a large amount of scrap and defective waste. This waste is mixed with impurities such as metal shavings, paper scraps, and lint. Traditional recycling often involves multiple independently driven crushing, air-separating, and sorting devices connected in series. This not only results in large equipment footprints and high overall energy consumption due to the multi-motor drive, but also easily leads to jamming and leakage problems in the material conveying between different stations. At the same time, conventional electromagnetic impurity removal equipment can only perform fixed-point adsorption and cannot cover all loose materials. The recycled PVC material still retains a small amount of metal impurities, which can easily damage injection molding and extrusion molds during secondary processing, making it difficult to meet the raw material purity requirements for the re-production of Christmas tree leaves. The industry urgently needs to design a waste recycling device for PVC Christmas tree leaf production to solve this problem. Summary of the Invention

The sorting frame 31 is inclined, and guide grooves 32 are symmetrically provided on the side wall of the sorting frame 31. A guide block 34 is slidably installed in the guide groove 32 and is connected to the shaking component. One end of the guide block 34 extends outside the guide groove 32 and is connected to an installation rod. 36. An electromagnet 37 is mounted on the mounting rod 36, and the electromagnet 37 is located on the upper side of the sorting chamber; a crushing rod 6 is provided in the housing 3, and a drive assembly is mounted on the housing 3. The crushing rod 6 is connected to the drive assembly, and a transmission assembly is connected to the drive assembly. The transmission assembly is connected to the fan blade 18, and the drive assembly is connected to the vibration assembly; the drive assembly includes a dual-axis motor 4, which is mounted on the housing 3. A first drive shaft 5 and a second drive shaft 8 are mounted on the dual-axis motor 4. The end of the first drive shaft 5 away from the dual-axis motor 4 extends into the housing 3, and the crushing rod is mounted on the first drive shaft 5; the transmission assembly includes a transmission shaft 10, one end of which is rotatably connected to the base 1, and a connecting unit 9 is mounted on the other end of the transmission shaft 10. The end away from the drive shaft 10 is connected to the second drive shaft 8. A driven shaft 19 is rotatably mounted on the side wall of the separation chamber 12. A connecting mechanism 21 is mounted on one end of the driven shaft 19. A fan blade 18 is mounted on the end of the driven shaft 19 away from the connecting mechanism 21. The end of the connecting mechanism 21 away from the driven shaft 19 is connected to the drive shaft 10. The transmission mechanism includes symmetrically arranged vertical plates 23. The vertical plates 23 are mounted on the receiving platform 22. A rotating shaft 24 is rotatably mounted on the vertical plates 23. A conveying unit 25 is mounted through the vertical plates 23 at one end of the rotating shaft 24. The end of the conveying unit 25 away from the rotating shaft 24 is connected to the drive shaft 10. Three actuating rods 26 are arranged in a ring on the rotating shaft 24. The actuating rods 26 are located at the bottom of the sorting frame 31 and are in intermittent contact with the bottom of the sorting frame 31.The vibration assembly also includes a reciprocating unit, one end of which is connected to the rotating shaft 24, and the other end of which, away from the rotating shaft 24, is connected to the guide block 34.

[0024] In this embodiment, the operator directly feeds the PVC Christmas tree leaf scraps and defective products generated on the production line into the top chamber 3. After starting the dual-axis motor 4, the first drive shaft 5 drives multiple sets of staggered crushing rods 6 inside the chamber 3 to rotate at high speed. Through a combination of shearing and impact, large pieces of PVC branches and plastic bases 1 are completely crushed into uniform 5-10mm fragments, avoiding the problem of excessively large particles blocking subsequent channels. Under its own weight, the crushed material falls uniformly into the separation chamber 12 from the feed inlet 17 at the top through the discharge port 7 on the bottom wall of the chamber 3 and the connecting pipe. The second drive shaft 8 of the dual-axis motor 4 drives the transmission shaft 10 to rotate through a coupling. The transmission shaft 10 then drives the driven shaft 19 and the fan blades 18 to rotate synchronously through a synchronous belt transmission mechanism, forming a stable directional airflow inside the sealed separation chamber 12. PVC scraps, being dense, fall directly to the bottom discharge port 16 and are discharged. Meanwhile, mixed paper scraps, lint, and light dust are carried by the airflow and blown out through the through-hole 20 at the end of the separation chamber 12, eventually entering the matching collection box 14. The ventilation holes 15 on the side wall of the collection box 14 ensure smooth airflow while preventing light impurities from overflowing and causing dust pollution in the workshop. The PVC scraps, after being air-separated, fall from the discharge port 16 into the inclined sorting frame 31. The rotating shaft 24 rotates synchronously under the drive of the transmission unit. Three actuating rods 26 in a ring array on the rotating shaft 24 intermittently strike the bottom of the sorting frame 31, causing the sorting frame 31 to vibrate at a stable high frequency, pushing the scraps slowly downwards along the inclined surface of the sorting chamber. During this process, the scraps are loosened and flattened, preventing material from piling up. Finally, they fall from the collection port 39 at the end of the sorting chamber into the receiving trough of the receiving platform 22, completing the coarse sorting process.

[0025] Furthermore, the connecting unit 9 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0026] Furthermore, both the connecting mechanism 21 and the conveying unit 25 can be gear sets or worm gears and worm wheels, which will not be described in detail here.

[0027] Please see Figures 1 to 7As an embodiment of the present invention, the reciprocating unit includes a rotating shaft 28, the two ends of which are rotatably connected to the side walls of symmetrically arranged vertical plates 23. A driven gear 29 is mounted on the rotating shaft 28, and a half gear 27 is mounted on the rotating shaft 24. The half gear 27 and the driven gear 29 mesh intermittently. A drum 30 is mounted on the rotating shaft 28, a guide roller is mounted on the sorting frame 31, and a pull rope 33 is mounted on the drum 30. The end of the pull rope 33 away from the drum 30 is wound around a guide roller. The guide roller extends along the pull rope 33 into the guide groove 32 and connects to the side wall of the guide block 34. An elastic component 40 is provided at the end of the guide block 34 away from the pull rope 33, and the end of the elastic component 40 away from the guide block 34 is connected to the side wall of the guide groove 32. The mounting rod 36 is rotatably connected to the guide block 34, and both ends of the mounting rod 36 penetrate the side wall of the guide block 34 and are connected to the mating gear 35. A toothed plate 38 is meshed on one side of the mating gear 35, and the toothed plate 38 is mounted on the sorting frame 31.

[0028] In this embodiment, when the rotating shaft 24 rotates continuously, the half gear 27 mounted on the rotating shaft 24 rotates synchronously with the shaft and intermittently meshes with the driven gear 29 below: when the teeth of the half gear 27 mesh with the driven gear 29, it will drive the rotating shaft 28 and the drum 30 to rotate synchronously. The drum 30 winds up the pull rope 33, and the pull rope 33 passes around the guide roller and pulls the guide block 34 to slide smoothly along the guide groove 32, synchronously compressing the spring elastic component 40 inside the guide groove 32; when the toothless area of ​​the half gear 27 rotates to the meshing position... When the driven gear 29 loses its driving force, the compressed elastic component 40 releases its elasticity, pushing the guide block 34 to reset in the opposite direction. This cycle repeats, driving the mounting rod 36 and electromagnet 37 to perform horizontal reciprocating linear motion above the sorting chamber, covering the entire length of the sorting chamber. The mounting rod 36 and the guide block 34 are connected by a rotating structure. At the two ends of the mounting rod 36 extending out of the guide block 34, a mating gear 35 is fixedly installed. The mating gear 35 is engaged with the toothed plate 38 fixed to the side wall of the sorting frame 31 throughout the entire process. During the reciprocating movement of the mounting rod 36 driven by the guide block 34, the mating gear 35 rolls along the toothed plate 38, driving the mounting rod 36 and electromagnet 37 to rotate 360° synchronously. The rotating electromagnet 37 can sweep over all the loose and flattened PVC material below without dead angles, completely adsorbing and carrying away the metal fragments and iron filings mixed in, ultimately obtaining qualified PVC recycled material with a purity of over 99%, which fully meets the raw material requirements for the secondary production of Christmas tree leaves.

[0029] Furthermore, the elastic component 40 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0030] The working principle of this invention is as follows: After the dual-shaft motor 4 is started, the first drive shaft 5 drives the crushing rod 6 inside the housing 3 to rotate at high speed, cutting the PVC Christmas tree leaf scraps into uniform fragments of 5-10mm. Under its own weight, the material enters the separation chamber 12 through the material drop channel. The second drive shaft 8 drives the fan blade 18 to rotate synchronously, forming a directional airflow in the chamber that blows light impurities such as paper scraps and lint into the collection box 14. The denser PVC fragments fall directly into the sorting frame 31. The rotating shaft 24 rotates synchronously with the transmission shaft 10, and the actuating rod 26 intermittently taps the bottom of the sorting frame 31, causing the material to shake and spread out at high frequency, preventing it from piling up and clumping together. The half gear 27 rotates with the rotating shaft 24, and drives the drum 30 to wind and unwind the rope 33 through meshing transmission. This drives the guide block 34 to reciprocate along the guide groove 32. The mating gears 35 at both ends of the mounting rod 36 roll along the tooth plate 38, driving the electromagnet 37 to move horizontally and reciprocate while rotating 360°. This allows for the adsorption of metal debris mixed in the PVC material without dead angles, ultimately yielding qualified recycled PVC material with a purity of over 99%.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
