Description

Technical Field

[0001] The invention relates to the field of plastic waste recycling, and in particular to a recycling and processing device for packaging plastic waste. Background Art

[0002] The recycling and processing device for packaging plastic waste is a device that uses rotating blades or toothed rollers to cut and tear plastic waste into small pieces. The motor drives the main shaft and the blades installed on the main shaft to rotate at high speed. After the plastic enters the crushing chamber, it is crushed by the impact, shearing and squeezing of the blades.

[0003] The publication number is CN216027125U, which discloses a plastic waste recycling and processing device based on biodegradation technology, including a base plate, a feed hopper is fixed on the upper end surface of the base plate, a mounting frame is fixedly connected to the front of the feed hopper, two rotating shafts are rotatably connected in the feed hopper, crushing rollers are fixedly connected to the surfaces of the two rotating shafts, one end of the two rotating shafts passes through the front of the feed hopper and is fixedly connected to gears, a material distribution box is fixedly connected to the upper end surface of the base plate, and a screening rod is fixedly connected in the material distribution box. With the rapid development of the modern packaging industry, the output of packaging plastic waste is increasing day by day. These wastes not only occupy a large amount of land resources, but also cause serious pollution to the environment because they are difficult to degrade naturally. Driven by the concept of sustainable development, the recycling and treatment of packaging plastic waste has become a key task in the field of environmental protection.

[0004] Crushing plastic bags is a crucial pre-processing step in the entire recycling process. After being crushed, the volume of plastic bags is reduced, which is convenient for subsequent transportation, sorting and reprocessing. By crushing, large-sized plastic bags can be converted into small pieces, improving the efficiency and quality of subsequent processing.

[0005] At present, the packaging plastic waste recycling and processing devices widely used in the market mostly use rotating blades to crush plastic bags. This method can achieve the initial crushing of plastic bags to a certain extent, but it has obvious limitations. As a polymer material, plastic bags have excellent toughness and ductility. When they come into contact with high-speed rotating blades, they are not easy to be cut off quickly due to their own physical properties. On the contrary, the plastic bags are easily driven by the blades, move along the rotation direction of the blades, and gradually entangle on the blades.

[0006] As the number of entangled plastic bags continues to increase, the operating efficiency of the crushing device drops sharply. After the blade is entangled, the effective cutting area is reduced, and the number of plastic bags cut at a single time is greatly reduced, making the crushing amount per unit time unable to meet production needs. At the same time, the entangled plastic bags increase the rotation resistance of the blade, and the motor needs to consume more electricity to maintain the operation of the blade, resulting in a significant increase in energy consumption. Excessive energy consumption not only increases the cost of recycling and processing, but may also cause motor overheating, shorten the service life of the motor, and even cause equipment failure, resulting in production interruption. In addition, in order to clean the plastic bags entangled on the blade, the operator has to shut down frequently, which not only wastes a lot of time, but also increases labor costs, seriously affecting the continuity and efficiency of the entire recycling process.

[0007] To solve the above problems, a device for recycling and treating packaging plastic waste is proposed. Summary of the invention

The upper end of the second baffle 607 is an inclined surface, and the outer side surface of the second baffle 607 is fitted with the inner side surface of the first hole 602, so that the scraper 506 can push the second baffle 607 to move up and down.

[0035] In order to reduce the movement of plastic bags following the blade 407 and thus improve the crushing efficiency, the specific operation is as follows: start the first motor 401 to drive the first rotating disk 402 and the rotating roller 403 to rotate, so that the first slide 404, the first slider 405, the first baffle 406 and the first baffle 406 rotate, so that the first connecting rod 410 and the first guide rod 409 rotate, because there are multiple first guide grooves 408, and the appearance structure shape of the first guide grooves 408 is "V" shaped, and the multiple first guide grooves 408 are interconnected, and the first slide grooves 404 are multiple, and the inner side surface of the first slide groove 404 is connected to the outer side surface of the first slider 405. The sides are fitted, and the outer width of the first slide groove 404 is greater than the inner width of the first slide groove 404. The central axis of the first slide groove 404 is parallel to the central axis of the rotating roller 403, so that the first guide rod 409 is pushed on the edge of the first guide groove 408, so that the first connecting rod 410, the first baffle 406 and the first slider 405 are pushed to reciprocate along the trajectory of the first slide groove 404, so that the blade 407 reciprocates when rotating. Because when the blade 407 only rotates, the plastic bag is mainly subjected to the tangential force along the rotation direction of the blade 407. Under the action of this single-direction force, the plastic bag is easy to move along the rotation direction and produce a following phenomenon. When the blade 407 reciprocates, the situation is quite different. It not only generates a rotational tangential force, but also brings lateral or longitudinal forces. The directions and magnitudes of these forces are constantly changing, making it difficult for the plastic bag to stably follow the movement of the blade 407, thereby reducing the following movement. At the same time, when the blade 407 simply rotates, the contact points and the number of cuts with the plastic bag are limited. The plastic bag has a chance to follow the movement during the interval between two cuts. The reciprocating motion of the blade 407 can increase the contact points and improve the cutting frequency. The plastic bag is cut more times per unit time, and each cut interferes with its motion state, making it more inclined to be shredded rather than following. In addition, the reciprocating motion of the blade 407 can also generate vibrations and airflow disturbances in the surrounding space, which exert additional force on the plastic bag, causing its position and posture to change continuously, disrupting the following trend, and making it difficult to stably adhere to the blade 407 or move along its trajectory, further reducing the following movement of the plastic bag. In summary, the following movement of the plastic bag is reduced, the probability of the plastic bag participating in the crushing process is increased, and the crushing effect is improved.

[0036] Since the blades 407 perform reciprocating motion while rotating, when a longer plastic bag is caught by a plurality of blades 407 at the same time, the blades 407 reciprocate, thereby increasing the probability of the longer plastic bag being broken and improving the breaking effect.

[0037] Since the plastic bottle is elastic, it is easy to bounce off when the blade 407 rotates, which reduces the crushing efficiency. The specific operation is as follows:

[0038] Through the control of the controller 610, when the first motor 401 rotates, the second motor 501 is also driven to rotate, and the second rotating disk 502 and the second guide groove 503 are driven to rotate. Because the second guide groove 503 is composed of two groups of circular arc grooves facing opposite directions, and the two groups of circular arc grooves facing opposite directions are connected to each other, and because the connection method between the scraper 506 and the shell 1 is a sliding connection, the edge of the second guide groove 503 pushes the second guide rod 504 to drive the first pull rod 505 and the scraper 506 to move toward the middle or to both sides, and then drives the second slide groove 507, the second slider 508 and the pressure plate 509 to move toward the middle or to both sides, and drives the third guide rod 511 to move downward or upward along the trajectory of the third guide groove 510, so that the pressure plate 509 and the second slider 508 move downward or upward along the trajectory of the second slide groove 507, squeeze the inner plastic bag and plastic bottle, reduce the movement space of the plastic bottle, so that the plastic bottle can be better crushed by the blade 407, and the crushing effect is improved.

[0039] Since the plastic bottle has a chance of being bounced off by the blade 407, when the scraper 506 moves to both sides, the plastic bottle is bounced off and the plastic bag is bounced off with it. When the scraper 506 moves inward, it drives the plastic bag and the plastic bottle to move toward the middle. When the plastic bottle is bounced off and the plastic bag is bounced off with it, a collision occurs. The plastic bag and the plastic bottle will be rearranged, so that the subsequent crushing effect is better.

[0040] Because the side of the lower end of the scraper 506 close to the rotating roller 403 is closer to the rotating roller 403 than the side of the upper end of the pressure plate 509 close to the rotating roller 403, the scraper 506 moves toward the middle, and the bottom of the scraper 506 will hit it first, while the pressure plate 509 is not closed. The scraper 506 and the pressure plate 509 push the air inside to the outside. At this time, the blade 407 is reciprocating horizontally, so that the gap between the plastic bag and the plastic bottle becomes larger, so that the dust closer to the blade 407 escapes faster under the push of the scraper 506 and the pressure plate 509. At this time, the spray tube 512 is spraying, so that the dust can merge with the water mist faster and fall.

[0041] When discharging is required, the cylinder 603 is controlled by the controller 610 to drive the second support plate 604 to move downward. Since the width of the upper end of the second pull rod 606 is smaller than the width of the lower end of the second pull rod 606, and the outer side surface of the lower end of the second pull rod 606 fits with the inner side surface of the groove 605, the second support plate 604 drives the second pull rod 606 to move downward, and drives the second baffle 607 to move downward. At this time, the side of the scraper 506 close to the center of the rotating roller 403 fits. Since the upper end of the second baffle 607 is an inclined surface, and the outer side surface of the second baffle 607 fits with the inner side surface of the first hole 602, the downward movement of the second baffle 607 forms a negative pressure phenomenon on the inner side of the first hole 602. At this time, the scraper 506 is controlled to open a certain distance to both sides, so that the upper end of the first hole 602 is opened, and the debris on the inner side of the scraper 506 is pushed downward to the inner side of the discharge trough 609 under the pressure from above, so that the discharging is faster.
