Description

Technical Field

[0002] Plastic solid waste recycling refers to the systematic collection, sorting, cleaning, and processing of discarded plastic products, transforming them into usable recycled plastic raw materials or new products. Its core goal is to achieve a closed-loop utilization of plastic resources, reduce dependence on virgin petroleum resources, minimize environmental pollution, and conserve energy. This typically involves melt regranulation or chemical recycling, depolymerization, and subsequent polymerization of monomers, aiming to reintegrate waste into the production cycle, transforming waste into valuable resources.

The water bottles can be placed in the device in sequence to realize the sequential flattening and recycling of the water bottles. The recycling operation is simple and easy, and the entire process does not require manual intervention; the crushing needle in the exhaust mechanism will extend due to the action of the cam, and then the water bottle will be punctured under the joint action of the crushing needle and the inner wall of the compression chamber, and the air in the water bottle will be discharged, which is convenient for subsequent flattening and recycling.

[0047] The cutting blade 203 has an inclined surface on one side close to the axis of the feeding barrel 201, and the inclined surfaces of the cutting blades 203 are used to feed and tear labels on the plastic bottles.

[0048] With the designed feeding and label-tearing assembly 2, when the external feeding device feeds the recycled plastic bottles into the loading barrel 201, the continuously fed plastic bottles can enter the loading barrel 201 in sequence through the feeding abutment. The multiple cutting knives 203 on the inner circumference of the loading barrel 201 can cut the outer circumference of the passing plastic bottles under the action of the inclined surface.

A plurality of fixed blocks 304 are connected around the bottom of the rotating ring along the axis. A tearing roller 307 is provided on one side of the fixed block 304. The tearing roller 307 rotates around the discharge barrel 4 to scrape the outer surface of the plastic bottle and then cut it for packaging;

[0051] A driving gear 302 is meshed with one side of the driven gear ring 301, and a driving motor 303 is provided on the top of the driving gear 302. The driving motor 303 is installed on the outer side of the fixing ring 202;

[0052] The scraping assembly 3 also includes a suction hood 310, which is sleeved on the outside of the top of the discharge barrel 4. The label tearing roller 307 and the fixed block 304 are both located in the suction hood 310. The inner side of the suction hood 310 is connected to an inner mask 311. The inner cavity of the inner mask 311 is connected along the axis to a plurality of folding plates 312. A plurality of shifting rods 313 are arranged in an array on one side of the folding plates 312. The folding plates 312 and the shifting rods 313 are used to scrape and cut labels through the surrounding movement.

A groove is provided on one side of the rotating block 306 located outside the slot, and the label-tearing roller 307 is rotatably connected to the groove. One side of the rotating block 306 is connected to an elastic part 308, and the other end of the elastic part 308 is connected to the outer side of the sleeve 305 through a mounting block 309.

[0054] The outer circumference of the label-tearing roller 307 is surrounded by a plurality of convex points, and the outer circumference of the label-tearing roller 307 is surrounded by a plurality of grooves along the axis. The designed convex points can maintain the contact friction of the label-tearing roller 307. Cover plates 9 are connected to both sides of the processing shell 1.

[0055] Specifically: through the designed scraping assembly 3, when the label is cut and separated by the cutting knife 203, the output shaft of the driving motor 303 is rotated to drive the driving gear 302 to rotate, and the rotation of the driving gear 302 can drive the driven gear ring 301 to rotate, and the rotation of the driven gear ring 301 can drive the multiple label-tearing rollers 307 at the bottom to rotate. The rotation of the label-tearing roller 307 can partially pull the separated label packaging strip, and the label strip can be separated from the bottle body after being pulled. At this time, the negative pressure suction device connected to the outside of the suction hood 310 performs negative pressure suction, and the pulled and separated label packaging strip can pass into the inner side of the folding plate 312 under negative pressure, and the moving rod 313 on the surface of the folding plate 312 can fully peel the label from the label-tearing roller 307, which is conducive to quickly separating and peeling the label on the bottle surface and facilitating subsequent recycling;

[0060] The two sides of the chute are connected to the limiting sleeve 503, which limits the lateral displacement of the counterweight rod 502 in the chute;

[0061] The outer array of the breaker rod 505 is provided with a plurality of sliding pads 506 , and the outer end of the breaker rod 505 is connected to a blocking ring 507 , which blocks the plastic bottle body from being stuck outside the breaker rod 505 through the blocking ring 507 .

[0062] When the bottle body is fully compressed and nested outside the crushing rod 505, the centrifugal counterweight rod 502 can knock the corresponding vibrating rod 504. When the vibrating rod 504 moves inside the crushing rod 505, it can knock the plastic bottle body forward. After being knocked by the vibrating rod 504, the plastic bottle body can be separated from the crushing rod 505, thereby preventing the plastic bottle body of 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.

The plastic bottle body blocked by the barrier portion 6 can be discharged outward through the discharge pipe by gravity, which is convenient for subsequent sorting.
