Description

Technical Field

[0001] This invention relates to the field of plastic crushing technology, and more particularly to a plastic waste recycling and crushing equipment. Background Technology

[0002] Plastic waste is difficult to degrade in the natural environment, and long-term accumulation will cause soil pollution, water damage and ecological harm. At the same time, the production of petroleum-based plastics consumes a large amount of non-renewable resources. Therefore, the recycling and reuse of plastic waste has become an important way to alleviate environmental pressure and achieve resource recycling. The crushing equipment is designed for the efficient crushing and processing of various types of plastic waste. During operation, waste plastic enters the crushing chamber through the feed inlet. It is subjected to shearing, tearing and extrusion between the high-speed rotating crushing roller and the fixed cutter head, and is crushed into small pieces of uniform size. The equipment can adjust the crushing gap according to the material characteristics to adapt to the processing needs of plastics of different softness and hardness, ensuring crushing efficiency and output quality.

[0003] After being washed, sorted and dried, the crushed plastic fragments can be widely used as recycled raw materials in many fields. On the one hand, they can be directly melted and granulated, and then re-injected or extruded into new plastic products. On the other hand, they can be used to produce wood-plastic composites, plastic modifiers and fuel rods, etc., to realize the high-value recycling of plastic resources and promote green and low-carbon development.

[0004] Existing plastic waste recycling and crushing equipment mostly adopts a single crushing chamber structure, which cannot process materials in separate zones according to their characteristics. In actual recycling scenarios, hard plastics and soft films, as well as plastics of different colors or materials, often need to be crushed separately to avoid cross-contamination and ensure the purity of recycled materials. If traditional equipment is used, companies need to purchase multiple crushers to operate separately, which not only requires a large area and high equipment investment, but also makes material transportation cumbersome and increases energy consumption. At the same time, when encountering large pieces of plastic waste, the fixed-capacity single-chamber equipment is difficult to handle and lacks adaptability.

[0005] Therefore, a plastic waste recycling and crushing equipment is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a plastic waste recycling and crushing device.

[0008] In the above technical solution, the main crushing roller and the auxiliary crushing roller are both fixedly connected to the outer wall of the crusher with a drive gear and a driven gear, respectively. The drive gear and the driven gear mesh with each other, and the output end of the servo motor is fixedly connected to the drive gear.

[0009] In the above technical solution, a lower partition is fixedly connected to the middle of the inner side of the discharge hopper, the partition frame is set above the two crushing tooth rings, and a semi-circular groove adapted to the crushing tooth rings is opened at the bottom of the partition frame.

[0010] In the above technical solution, the locking mechanism further includes an upper bolt, countersunk holes are provided on the outer wall of the crushing tooth ring, and an upper threaded hole is provided on the inner side of the T-shaped ring groove. The upper bolt passes through the countersunk hole and is threaded into the upper threaded hole. A rectangular groove is provided through the side wall of the crushing tooth ring, and an upper rod is slidably connected to the bottom end of the rectangular groove. The bottom end of the upper rod is provided through the inner side of the T-shaped ring, and a positioning hole is provided on the inner side of the T-shaped ring groove relative to the position below the upper rod.

[0011] In the above technical solution, an upper spring is fixedly connected between the top end of the upper rod and the top end of the rectangular groove, and lower rods are fixedly connected to both sides of the outer wall of the upper rod.

[0012] In the above technical solution, the limiting mechanism further includes lower bolts, and two sets of lower bolts are provided, with three lower bolts in each set. An installation cavity is provided on the partition frame, and a sliding plate is laterally slidably connected to the inner side of the installation cavity. An L-shaped rectangular block is fixedly connected to the side wall of the sliding plate. The rectangular block is disposed through the inner side of the partition frame. A pair of right-angled plates with inclined surfaces are fixedly connected to the side wall of each rectangular block. Three threaded holes are equidistantly provided on the side wall of the insertion rod, and the lower bolt passes through the groove in the installation cavity and is threaded into the corresponding threaded hole.

[0013] In the above technical solution, the slide plate sidewall is further provided with a through hole. During installation, one of the lower bolts passes through the through hole and is threaded into the corresponding lower threaded hole. Several lower springs are fixedly connected between the rectangular block sidewall and the inner side of the mounting cavity.

[0014] In the above technical solution, a flip plate is rotatably connected to the inner side of the partition frame, a top plate is fixedly connected to the top of the flip plate, a pair of fixing bolts are provided through the top plate, the bottom ends of the fixing bolts are threaded to the top of the partition frame, and fan-shaped folding covers are fixedly connected between the two sides of the flip plate and the outer wall of the partition frame.

[0015] In the above technical solution, the inner ends of the partition frame are provided with arc-shaped grooves, and the outer sides of the flip plate are fixedly connected with guide rods for insertion into the arc-shaped grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention enables flexible switching between single and dual chambers in the crushing equipment through the design of structures such as partition frames and crushing toothed rings. This effectively solves the problem of the single function of traditional equipment. In dual chamber mode, different types or colors of plastic waste can be processed simultaneously, avoiding cross-contamination and improving the purity of recycled materials. In single chamber mode, the crushing chamber volume is doubled after the partition is removed, which can easily handle large materials such as pipes and plates without the need to purchase additional large equipment. This multi-purpose machine significantly reduces equipment investment and site occupation costs, and adapts to the actual needs of recycling sites for diverse materials.

[0017] 2. This invention, through the setting of the flip plate on the partition frame, can flexibly adjust the angle of the flip plate according to the material characteristics, thereby expanding the material discharge space of one of the chambers in the dual-chamber mode, optimizing the path of the material into the crushing roller, and when processing long strip plastics, the tilting can guide the material to enter the biting area in a directional manner, reducing entanglement and jamming, and improving crushing efficiency. When processing regular crushed materials, the flip plate returns to the vertical state to ensure clear chamber separation. This design takes into account both the smooth feeding of special materials and the stable chamber separation of regular operations, enhancing the equipment's adaptability to complex recycling scenarios.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] In practical use, it has been found that existing plastic waste recycling and crushing equipment mostly adopts a single crushing chamber structure, which cannot process materials in different zones according to their characteristics. In actual recycling scenarios, hard plastics and soft films, as well as plastics of different colors or materials, often need to be crushed separately to avoid cross-contamination and ensure the purity of recycled materials. If traditional equipment is used, enterprises need to purchase multiple crushers to operate separately, which not only requires a large area and high equipment investment, but also makes material transportation cumbersome and increases energy consumption. At the same time, when encountering large pieces of plastic waste, the fixed-capacity single-chamber equipment is difficult to handle and lacks adaptability. To solve the above problems, the following structure was invented.

[0023] like Figures 1-14 The plastic waste recycling and crushing equipment shown includes a crusher 1, a servo motor 2 with an absolute encoder fixedly connected to the crusher 1. Each position of the absolute encoder disk corresponds to a unique code. After power failure, the current position information is retained by a battery or magnet. When the servo system restarts, it directly reads the absolute position data of the encoder and drives the servo motor 2 to accurately restore the coordinates before stopping, without the need for zeroing and origin finding, achieving complete overlap between the stopping and starting positions. A discharge hopper 36 is fixedly connected to the bottom of the crusher 1. A main crushing roller 3 and an auxiliary crushing roller 4 are rotatably connected inside the crusher 1. T-shaped ring grooves 5 are provided in the middle of the outer wall of the main crushing roller 3 and the auxiliary crushing roller 4. The T-shaped ring grooves 5 on the main crushing roller 3 and the T-shaped ring grooves 5 on the auxiliary crushing roller 4 are staggered. T-shaped rings 6 are rotatably connected to the inner side of the T-shaped ring grooves 5. Crushing tooth rings 7 are fixedly connected to the outer wall of the T-shaped rings 6. The crushing tooth rings 7 are provided with a locking mechanism for locking in the T-shaped ring grooves 5. A partition frame 8 is inserted into the middle of the inner side of the crusher 1. Grooves 9 are provided on both sides of the partition frame 8. Insert rods 10 for inserting into the grooves 9 are fixedly connected to the inner side of the crusher 1. A limiting mechanism for locking the partition frame 8 on the insert rods 10 is also provided. The main crushing roller 3 and the auxiliary crushing roller 4 are both fixedly connected to the outer wall of the crusher 1 with a drive gear 11 and a driven gear 12. The drive gear 11 and the driven gear 12 mesh with each other. The output end of the servo motor 2 is fixedly connected to the side of the drive gear 11.

[0024] During single-chamber operation, plastic waste is placed into the crusher 1. The servo motor 2 drives the drive gear 11 to rotate, which in turn drives the meshing driven gear 12 to rotate. This drives the main crushing roller 3 and the auxiliary crushing roller 4 to rotate towards the center simultaneously. The crushing teeth on the main crushing roller 3 and the auxiliary crushing roller 4 mesh with each other to crush the plastic waste. Finally, the crushed plastic particles are discharged through the discharge hopper 36.

[0025] A lower partition 13 is fixedly connected to the middle of the inner side of the discharge hopper 36. The lower partition 13 isolates the crushed plastic particles. Moreover, the lower partition 13 does not need to be adjusted and can be used in both single-chamber and double-chamber modes. The partition frame 8 is located above the two crushing toothed rings 7. The bottom end of the partition frame 8 is provided with a semi-circular groove 14 that matches the crushing toothed rings 7. By setting the semi-circular groove 14, the upper part of the crushing toothed rings 7 can be blocked inside the partition frame 8 when the partition frame 8 is inserted.

[0026] The locking mechanism includes an upper bolt 15, countersunk holes on the outer wall of the crushing tooth ring 7, and an upper threaded hole 16 on the inner side of the T-shaped ring groove 5. The upper bolt 15 passes through the countersunk hole and is threaded into the upper threaded hole 16. A rectangular groove 17 is provided through the side wall of the crushing tooth ring 7. An upper rod 18 is slidably connected to the bottom end of the rectangular groove 17. The bottom end of the upper rod 18 is provided through the inner side of the T-shaped ring 6. A positioning hole 19 is provided on the inner side of the T-shaped ring groove 5 relative to the position below the upper rod 18.

[0027] An upper spring 20 is fixedly connected between the top of the upper rod 18 and the top of the rectangular groove 17, and a lower rod 21 is fixedly connected to both sides of the outer wall of the upper rod 18.

[0028] The limiting mechanism includes lower bolts 22, and there are two sets of lower bolts 22, with three lower bolts 22 in each set. The partition frame 8 has an installation cavity 23. A sliding plate 24 is laterally slidably connected to the inner side of the installation cavity 23. An L-shaped rectangular block 25 is fixedly connected to the side wall of the sliding plate 24. The rectangular block 25 passes through the inner side of the partition frame 8. A pair of right-angle plates 26 with inclined surfaces are fixedly connected to the side wall of the rectangular block 25. Three threaded holes 27 are equidistantly opened on the side wall of the insertion rod 10. The lower bolts 22 pass through the groove 9 from the installation cavity 23 and are threaded into the corresponding threaded holes 27.

[0029] The side wall of the slide plate 24 has a through hole 28. During installation, one of the lower bolts 22 passes through the through hole 28 and is threaded into the corresponding lower threaded hole 27. Several lower springs 29 are fixedly connected between the side wall of the rectangular block 25 and the inner side of the mounting cavity 23.

[0030] When it is necessary to adjust to the dual-chamber crushing mode, first stop the equipment and ensure that the stopping position of the servo motor 2 is the same as the initial position (that is, after the partition 8 is inserted, the rectangular block 25 is located next to the rectangular groove 17), and disconnect the power to the equipment. Then, use a tool to unscrew the upper bolts 15 on the two crushing tooth rings 7 from the corresponding upper threaded holes 16 to release the initial restriction on the crushing tooth rings 7. At this time, since the upper rod 18 is inserted into the positioning hole 19, the crushing tooth rings 7 will not rotate arbitrarily. Then, the partition 8 can be taken out, the partition 8 can be inserted into the crusher 1, the insertion rod 10 can be inserted into the corresponding groove 9, and the crushing tooth rings 7 can be inserted into the corresponding semi-circular groove 14. Then, one of the lower bolts 22 can be threaded through the through hole 28 and connected to the corresponding lower threaded hole 27. During this process, the sliding plate 24 will be squeezed and moved inside the mounting cavity 23, thereby pushing the rectangular block 25 and the right-angle plate 26 out of the mounting cavity 23 and inserting them into the rectangular slot 17, and compressing the lower spring 29. At this time, the right-angle plate 26 will move below the lower rod 21. Since the upper rod 18 can only slide up and down, under the pressure of the inclined surface of the right-angle plate 26, the lower rod 21 will be pushed upward, and the upper rod 18 will be moved upward. The upper spring 20 is compressed, thereby releasing the limiting position of the crushing tooth ring 7 on the main crushing roller 3 or the auxiliary crushing roller 4. At this time, the rectangular block 25 is inserted into the rectangular groove 17, so the crushing tooth ring 7 is limited in the partition frame 8. Then, the other two lower bolts 22 are threaded through the mounting cavity 23 and connected to the other two lower threaded holes 27. The above operation is repeated to thread another set of lower bolts 22 onto the partition frame 8 on the other side (since the two crushing tooth rings 7 are staggered, the installation positions of the lower bolts 22 on both sides of the partition frame 8 are not on the same side). Finally, power on the crusher 1 and start the servo motor 2. At this time, the main crushing roller 3 and the auxiliary crushing roller 4 will rotate under the drive of the servo motor 2. However, the crushing tooth ring 7 is not connected to the main crushing roller 3 and the auxiliary crushing roller 4, so it will not rotate. At this time, the T-ring 6 will rotate in the T-ring groove 5, thereby realizing dual-chamber crushing. When it is necessary to adjust back, the above operation can be repeated in reverse.

[0031] In summary, the above structural design enables flexible switching between single and dual chambers in the crushing equipment, effectively solving the problem of limited functionality in traditional equipment. In dual-chamber mode, different types or colors of plastic waste can be processed simultaneously, avoiding cross-contamination and improving the purity of recycled materials. In single-chamber mode, the crushing chamber volume doubles after the partition is removed, easily handling large materials such as pipes and plates without the need to purchase additional large equipment. This multi-purpose design significantly reduces equipment investment and site occupancy costs, adapting to the diverse material needs of recycling sites.

[0032] Based on the above embodiments, it was found during use that the partition 8 is a fixed vertical structure and the angle cannot be adjusted according to the material characteristics. When processing long strips of plastic, the fixed partition cannot guide the material into the optimal crushing position, resulting in poor feeding and low crushing efficiency, making it difficult to adapt to complex and ever-changing recycling scenarios. To solve the above problems, further improvements were made to the above structure.

[0033] A flip plate 30 is rotatably connected to the inner side of the partition 8. A top plate 31 is fixedly connected to the top of the flip plate 30. A pair of fixing bolts 32 are provided through the top plate 31. The bottom ends of the fixing bolts 32 are threaded to the top of the partition 8. Fan-shaped folding covers 33 are fixedly connected between the two sides of the flip plate 30 and the outer wall of the partition 8. The setting of the fan-shaped folding covers 33 can prevent plastic particles from falling into another chamber from the gap between the flip plate 30 and the partition 8.

[0034] Both ends of the inner side of the partition frame 8 are provided with arc-shaped grooves 34. Both sides of the outer wall of the flip plate 30 are fixedly connected with guide rods 35 for insertion into the arc-shaped grooves 34. It should be noted that the end of the arc-shaped groove 34 is made of magnetic material, and the guide rod 35 is made of iron. After the guide rod 35 is flipped to the other end of the arc-shaped groove 34, it can be attracted and fixed, ensuring that the flip plate 30 will not shake randomly during the crushing process, thereby ensuring the stability of the equipment during operation.

[0035] In the dual-chamber mode, when it is necessary to change the material discharge space of one of the chambers, first unscrew the two fixing bolts 32 from the partition frame 8 to release the positional restrictions on the top plate 31 and the flip plate 30. Then push the flip plate 30 to flip, which will drive the guide rod 35 to flip in the arc groove 34 and open the fan-shaped folding cover 33, thereby completing the adjustment of the material discharge space of one area. During the material discharge process, the material can be guided to enter the biting area by tilting, realizing the dual-area crushing of long plastic waste. When it is necessary to adjust back, the above operation can be repeated in reverse.

[0036] In summary, the design of the above structure allows for flexible adjustment of the angle of the tilting plate 30 according to the material characteristics. This enables the expansion of the material discharge space in one of the chambers in dual-chamber mode, optimizes the path of material entering the crushing roller, and guides the material into the biting area by tilting when processing long strips of plastic, reducing entanglement and jamming, and improving crushing efficiency. When processing regular crushed materials, the tilting plate 30 returns to a vertical position to ensure clear chamber separation. This design balances smooth feeding of special materials with stable chamber separation in regular operations, enhancing the equipment's adaptability to complex recycling scenarios.
