Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of solid waste treatment, and particularly relates to a plastic solid waste recycling and treatment device. Background Art
[0002] The recycling of plastic solid waste refers to the process of systematically collecting, sorting, cleaning, and processing waste plastic products, and then re-converting them into reusable recycled plastic raw materials or new products. Its core goal is to achieve the closed-loop utilization of plastic resources, reduce dependence on primary petroleum resources, reduce environmental pollution, and save energy. This usually involves melt granulation or chemical recycling and depolymerization into monomers followed by repolymerization, aiming to reincorporate the waste into the production cycle and turn waste into treasure.
[0003] A Chinese invention patent with the publication number CN115889402A discloses a plastic water bottle automatic recycling and treatment device, including a support structure, a semi-shell, a side cover, a roller, a compression structure, a crescent body, a transmission mechanism, and an exhaust mechanism; the present invention has the characteristics of reasonable and simple structure, low production cost, and convenient installation. By placing water bottles into this device in sequence, the sequential flattening and recycling of water bottles can be achieved. Its recycling operation is simple and easy, and the entire process does not require manual intervention; the crushing needle in the exhaust mechanism will protrude due to the action of the cam, and then the water bottle will be punctured under the combined action of the crushing needle and the inner wall of the compression cavity, and the air in the water bottle will be discharged, facilitating subsequent flattening and recycling. However, in actual use, the label packaging on the bottle surface cannot be recycled. To avoid affecting the recycling granulation effect, label pre-removal is required. There is still label doping when the traditional method of removing labels by blowing air is used, and there is room for improvement. Summary of the Invention

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:
[0027] 1. In the present invention, through the designed feeding and label tearing assembly, when an external feeding device puts plastic bottles for recycling into the feeding cylinder, the continuously fed plastic bottles can enter the feeding cylinder in sequence through feeding and abutting. A plurality of cutting knives on the inner periphery of the feeding cylinder can cut the outer periphery of the passing plastic bottles under the action of the inclined plane. Through the cooperation of the plurality of cutting knives, the circular labels and packages on the outer surface of the bottle can be equally divided and cut off, and only the recyclable plastic bottle body can be retained, without the need for an additional label tearing and removing process, improving the recycling and processing efficiency.
[0028] 2. In the present invention, through the designed scraping component, after the label is cut and separated by the cutting knife, the driving motor can drive the driving gear and the driven gear ring to rotate. The rotation of the driven gear ring can drive multiple label tearing rollers at the bottom to rotate. The rotation of the label tearing rollers can partially traction the divided label packaging strip. After the label strip is tractioned, it can be separated from the bottle body. At this time, the negative pressure suction device connected to the outside of the air suction hood performs negative pressure suction. The tractioned and separated label packaging strip can enter the inside of the folding plate under negative pressure. The moving rod on the surface of the folding plate can fully strip the label from the label tearing roller, which is beneficial to quickly separate and remove the label on the bottle body surface and facilitate subsequent recycling.
[0029] 3. In the present invention, through the designed compression component, the driving part drives the compression roller to rotate. The rotation of the compression roller can drive the crushing rods on the outer peripheral side to rotate to compress the plastic bottle bodies falling from the feeding cylinder. The crushing rods can press against the bottle bodies to make them contact and compress with the impact plate. When the crushing rods continuously compress the plastic bottle bodies, they can pierce the plastic bottle bodies to discharge air and compress the bottle bodies. When the bottle bodies are fully compressed and nested outside the crushing rods, the centrifugal counterweight rods can strike the corresponding vibrating rods. When the vibrating rods move in the crushing rods, they can strike the plastic bottle bodies forward. After the plastic bottle bodies are struck by the vibrating rods, they can be separated from the crushing rods, which can avoid the plastic bottle bodies stuck in the sleeve affecting the subsequent compression effect. At the same time, the swinging sliding pads can synchronously squeeze the plastic bottle bodies, which is convenient to improve the separation effect of the plastic bottle bodies.

[0052] The scraping assembly 3 further includes an air suction hood 310. The air suction hood 310 is sleeved on the outer side of the top of the blanking cylinder 4. The label tearing roller 307 and the fixing blocks 304 are both located inside the air suction hood 310. An inner mask 311 is connected to the inner side of the air suction hood 310.

Through the designed bumps, the contact friction of the label tearing roller 307 can be maintained. Covers 9 are connected to both sides of the processing housing 1;
[0055] Specifically: Through the designed scraping component 3, after the label is cut and separated by the cutting knife 203, the rotation of the output shaft of the driving motor 303 can drive the driving gear 302 to rotate. The rotation of the driving gear 302 can drive the driven tooth ring 301 to rotate. The rotation of the driven tooth ring 301 can drive multiple label tearing rollers 307 at the bottom to rotate. The rotation of the label tearing rollers 307 can partially traction the divided label packaging strip. After the label strip is tractioned, it can be separated from the bottle body. At this time, the negative pressure suction device connected to the outside of the air suction hood 310 performs negative pressure suction.

[0057] Please refer to Figures 4 - 8 As shown in the figure, the compression component 5 includes a compression roller 501. Both sides of the compression roller 501 are rotatably connected to mounting plates 508. The mounting plates 508 are connected to one side of the inner cavity of the processing housing 1. A driving part is installed on one side of the mounting plate 508. The output shaft of the driving part is in transmission connection with the compression roller 501. A plurality of crushing rods 505 are connected around the outer periphery of the compression roller 501 along the axis. A vibrating rod 504 is slidably connected to the inner cavity of the crushing rod 505. By the rotation and centrifugation of the compression roller 501, the vibrating rod 504 squeezes the front-end compressed plastic bottle body;
[0058] The driving part includes a motor and a gear set connected to the output shaft of the motor, and the output shaft of the gear set is in transmission connection with the compression roller 501;
[0059] A sliding groove is opened at a position corresponding to the crushing rod 505 inside the compression roller 501. A counterweight rod 502 is slidably connected in the sliding groove. The counterweight rod 502 slides in the sliding groove to strike the end of the vibrating rod 504;
[0060] Both sides of the sliding groove are connected with limit sleeves 503 to limit the lateral displacement of the counterweight rod 502 in the sliding groove;
[0061] A number of sliding pads 506 are arrayed outside the crushing rod 505. A blocking ring 507 is connected to the outer end of the crushing rod 505. The plastic bottle body is blocked by the blocking ring 507 from being sleeved outside the crushing rod 505.
[0062] Specifically: Through the designed compression component 5, the driving part can drive the compression roller 501 to rotate. The rotation of the compression roller 501 can drive the crushing rod 505 on the outer peripheral side to rotate to compress the plastic bottles falling from the feeding cylinder 4. Moreover, the crushing rod 505 can press against the bottle body to make it contact and compress with the impact plate 7. When the crushing rod 505 continuously compresses the plastic bottle body, it can pierce the plastic bottle body to discharge air, thereby enabling more compression of the bottle body and improving the recycling efficiency. At the same time, when the bottle body is fully compressed and nested outside the crushing rod 505, the centrifugal counterweight rod 502 can strike the corresponding vibrating rod 504. When the vibrating rod 504 moves in the crushing rod 505, it can strike the plastic bottle body forward. After being struck by the vibrating rod 504, the plastic bottle body can be separated from the crushing rod 505, thus avoiding the plastic bottle body stuck in the sleeve from affecting the subsequent compression effect. At the same time, the swinging sliding pad 506 can synchronously squeeze the plastic bottle body, which is convenient for improving the separation effect of the plastic bottle body;

One side of the inner cavity of the processing housing 1 is connected with a blocking part 6, and the blocking part 6 is provided with a through groove for the crushing rod 505 to pass through;
[0064] Furthermore, through the designed blocking part 6, when the crushing rod 505 rotates to the blocking part 6, the blocking part 6 can make the compressed plastic bottle body separate from the crushing rod 505, thereby reducing the influence of the stacking of the bottle bodies outside the crushing rod 505 on the compression efficiency. The plastic bottle bodies blocked by the blocking part 6 can be discharged outward through the feeding pipe by gravity, which is convenient for subsequent sorting.
