Description

Technical Field

[0001] The present invention relates to the technical field of PET plastic recycling, and specifically relates to a PET plastic recycling and treatment device and a using method thereof. Background Art

[0002] PET, namely polyethylene terephthalate, has replaced some traditional packaging materials due to its advantages such as light weight, unbreakability, and low energy consumption, and is widely used in the fields of food, beverages, cosmetics, etc.

[0003] After a large amount of PET materials are used, the accumulation of a large number of waste PET bottles will also occupy land resources. Therefore, it is very necessary to recycle and treat them. This is a relatively common and simple treatment method on the market. The specific process is as follows: First, the recycled waste PET bottles are crushed into various fragments, and then subjected to cleaning steps such as hot washing, friction cleaning, dehydration, and drying to remove impurities and stains on the shredded plastic sheets, obtaining clean plastic sheets. Then, the clean plastic sheets are crushed into smaller sizes again and sent into a waste plastic granulator to make plastic particles that can be used for blow molding and remanufacturing.

[0004] From the above, it can be known that the recycling of PET bottles is inseparable from crushing equipment. Although the existing crushing equipment can crush plastic bottles through the crushing of cutting blades, there are still inevitable deficiencies. Among them, the device lacks a pre-degassing and compression mechanism, resulting in the inconvenience of quickly releasing the air inside the bottle body and the inconvenience of compressing the volume of the bottle body. When the crushing mechanism crushes the plastic bottle, there will be an explosion sound and the bottle body is too smooth, resulting in the inconvenience of quickly crushing it with the crushing tool. Therefore, a PET plastic recycling and treatment device and a using method thereof are proposed to solve the existing problems. Summary of the Invention

[0015] The present invention also discloses a method for using a PET plastic recycling and processing device, which specifically includes the following steps:

[0016] S1. PET plastic crushing: Start the driving motor, and through the meshing cooperation of two first gears, drive the two crushing shafts to drive the crushing cutters to rotate reversely, so that the plastic inside the processing frame is continuously crushed;

[0017] S2. Feeding, de-pressurizing and compressing: During the rotation of the crushing shaft, through the transmission cooperation of the first pulley and the first belt, the adapter shaft is synchronously rotated. The adapter shaft drives the multi-directional crankshaft to rotate synchronously through the meshing of two bevel gears. The crankshaft surfaces in different directions of the multi-directional crankshaft drive a plurality of moving plates to slide reciprocally synchronously, so that a plurality of moving plates on the same side form a wavy displacement as a whole. During the movement of two moving plates at the same height, the plastic bottles continuously fed into the top of the silo will be pierced by the thorn cones, and the two moving plates are brought into contact with each other synchronously, so that the pierced plastic bottles are successively compressed. When the moving plates slide and reset periodically, the sliding rod will contact and squeeze the baffle plate, so that the sliding rod drives the blanking frame to remove the plastic bottles stuck on the surface of the thorn cones until the plastic bottles fall into the inside of the silo;

[0018] S3. Quantitative feeding and transfer: During the rotation of the left adapter shaft, the adapter shaft drives the short shaft to rotate synchronously through the transmission cooperation of the second pulley and the second belt. The short shaft drives the cam to rotate. The cam rotates reciprocally to drive the handle activity frame up and down. The handle activity frame drives the toothed plate to reciprocally engage with the second gear. When the toothed plate descends and engages with the second gear, the second gear drives the rotating shaft to rotate. The rotating shaft is in extrusion cooperation with the card slot through the inclined plane of the single-sided inclined block. Since the hollow shaft is restricted by the anti-reverse cooperation of the ratchet and the pawl, the rotating shaft rotates idly by itself. When the toothed plate ascends and is reversely engaged with the second gear, the rotating shaft drives the hollow shaft to rotate through the contact cooperation between the flat surface of the single-sided inclined block and the card slot. The hollow shaft drives the material supporting and deflecting plate to intermittently rotate equidistantly in a circular motion. The intermittent equidistant rotation of a plurality of material supporting and deflecting plates will intermittently and relatively quantitatively feed the stored materials inside the silo into the inside of the processing frame;

[0019] Intermittent elastic pressing of materials: During the reciprocating descent of the handle activity frame, the cross plate is synchronously driven to descend. The cross plate drives the pressing frame to elastically descend through the elastic cooperation of the receiving cylinder, the telescopic rod and the third return spring. The reciprocating descent of the pressing frame elastically presses the plastic fed into the inside of the processing frame, so that the plastic is in close contact with the crushing cutters, accelerating the crushing;

[0020] S4. Vibration-accelerated blanking: During the reciprocating lifting of the cross plate, the cross plate synchronously drives the lifting plate to lift the blanking plate. The lifting of the blanking plate will increase the rotation angle, causing the accumulated material on the inclined surface to fall downward.

[0021] Beneficial effects

[0022] The present invention provides a PET plastic recycling and processing device and its use method. Compared with the existing technology, it has the following beneficial effects:

[0023] (1) For the PET plastic recycling and processing device and its use method, by arranging a degassing and compressing mechanism, a quantitative blanking mechanism, and an accelerating blanking mechanism that are used in cooperation with the crushing mechanism inside the bin, when the device crushes plastic bottles, through the above cooperation, it can simultaneously pierce and squeeze and compress the feeding of plastic bottles, prompting the gas inside the bottle body to be removed and the outer shape to be compressed, facilitating safer and faster crushing during the crushing process, and simultaneously carrying out directional blanking inside the processing frame and intermittently elastically pressing the material, prompting the plastic to be in close contact with the first gear, accelerating the crushing efficiency, and simultaneously reciprocatingly lifting the rotation angle of the blanking plate, prompting convenient blanking of the blanking plate.

[0024] (2) For the PET plastic recycling and processing device and its use method, by arranging a ratchet and a ratchet pawl between the hollow shaft and the bin, and arranging a single-sided inclined block and a card slot between the hollow shaft and the rotating shaft, when the tooth plate reciprocally meshes with the second gear, the rotating shaft can drive the hollow shaft to rotate intermittently and unidirectionally through the above cooperation.

[0025] (3) For the PET plastic recycling and processing device and its use method, by arranging a blanking frame on the side of the moving plate, the blanking frame can easily remove the plastic bottle on the surface of the stab cone through the reciprocating extrusion cooperation between the sliding rod and the baffle.

[0026] (4) For the PET plastic recycling and processing device and its use method, by setting the multi-directional crankshaft as crankshaft segments with different directions in multiple sections, several moving plates can form a wavy movement, facilitating the plastic bottle to be pierced and squeezed while also providing a falling channel downward.

[0050] The present invention also discloses a method for using a PET plastic recycling and processing device, which specifically includes the following steps:

[0051] S1. PET plastic crushing: Start the driving motor 401, and prompt the driving motor 401 to drive the two crushing shafts 402 to drive the crushing cutters 404 to rotate reversely through the meshing cooperation of the two first gears 403, so as to continuously crush the plastic inside the processing frame 3.

[0052] S2. Feeding, pressure relief and compression: During the rotation of the crushing shaft 402, synchronously through the transmission cooperation of the first pulley 510 and the first belt 511, prompt the adapter shaft 508 to rotate synchronously. The adapter shaft 508 drives the multi-directional crankshaft 507 to rotate synchronously through the meshing of the two bevel gears 509. The crankshaft surfaces at different positions of the multi-directional crankshaft 507 drive the multiple moving plates 501 to slide reciprocally synchronously, so that the multiple moving plates 501 on the same side form a wavy displacement as a whole. During the movement of the two moving plates 501 at the same height, the plastic bottles continuously fed into the top of the material bin 1 will be punctured by the thorn cones 502, and the two moving plates 501 are pressed together synchronously, so that the punctured plastic bottles are successively compressed. When the moving plate 501 slides and resets periodically, the sliding rod 505 will extrude and contact with the baffle 512, so that the sliding rod 505 drives the material discharging frame 504 to discharge the plastic bottles stuck on the surface of the thorn cone 502 until the plastic bottles fall into the interior of the material bin 1.

[0053] S3. Quantitative blanking and transfer: During the rotation of the left transfer shaft 508, the transfer shaft 508 synchronously drives the short shaft 611 to rotate through the transmission cooperation of the second pulley 612 and the second belt 613. The short shaft 611 drives the cam 614 to rotate. The reciprocating rotation of the cam 614 drives the handle movable frame 610 up and down. The handle movable frame 610 drives the toothed plate 615 to reciprocally engage with the second gear 604. When the toothed plate 615 descends and engages with the second gear 604, the second gear 604 drives the rotating shaft 603 to rotate. The rotating shaft 603 is in extrusion fit with the card slot 608 through the inclined plane of the single-sided inclined block 606. Since the hollow shaft 601 is restricted by the anti-reverse cooperation of the ratchet 620 and the pawl 622, the rotating shaft 603 idles by itself. When the toothed plate 615 ascends and engages reversely with the second gear 604, the rotating shaft 603 drives the hollow shaft 601 to rotate through the contact fit between the flat surface of the single-sided inclined block 606 and the card slot 608. The hollow shaft 601 drives the material supporting and deflecting plate 602 to intermittently rotate equidistantly around. The intermittent equidistant rotation of several material supporting and deflecting plates 602 will intermittently and relatively quantitatively blank the stored material in the material bin 1 into the processing frame 3;

[0054] Intermittent elastic material pressing: During the reciprocating descent of the handle movable frame 610, the cross plate 609 is synchronously driven to descend. The cross plate 609 drives the pressing frame 619 to elastically descend through the elastic cooperation of the receiving cylinder 616, the telescopic rod 617 and the third return spring 618. The reciprocating descent of the pressing frame 619 elastically presses the plastic fed into the processing frame 3, so that the plastic is in close contact with the crushing cutter 404, accelerating the crushing;

[0055] S4. Vibration-accelerated blanking: During the reciprocating lifting and lowering of the cross plate 609, the cross plate 609 synchronously drives the lifting plate 704 to lift the pouring plate 702. The lifting of the pouring plate 702 will increase the rotation angle, and the accumulated material on the inclined plane will fall off downward.

9. A method for using a PET plastic recycling and processing device, characterized in that: Specifically, it includes the following steps: S1. PET plastic crushing: Start the driving motor (401). The driving motor (401) drives the two crushing shafts (402) to drive the crushing cutters (404) to rotate in the reverse direction through the meshing of the two first gears (403), so that the plastic inside the processing frame (3) is continuously crushed. S2. Feeding, pressure - relieving and compressing: During the rotation of the crushing shaft (402), through the transmission cooperation of the first pulley (510) and the first belt (511), the adapter shaft (508) rotates synchronously. The adapter shaft (508) drives the multi - directional crankshaft (507) to rotate synchronously through the meshing of the two bevel gears (509). The crankshaft surfaces at different positions of the multi - directional crankshaft (507) drive a plurality of moving plates (501) to slide reciprocally synchronously, so that the plurality of moving plates (501) on the same side form a wavy displacement as a whole. During the movement of the two moving plates (501) at the same height, the plastic bottles continuously fed into the top of the silo (1) are punctured by the thorn cones (502), and the two moving plates (501) are attached to each other synchronously, so that the punctured plastic bottles are successively compressed. When the moving plate (501) slides and resets periodically, the sliding rod (505) contacts and presses against the baffle (512), so that the sliding rod (505) drives the blanking frame (504) to remove the plastic bottles stuck on the surface of the thorn cones (502) until the plastic bottles fall into the inside of the silo (1). S3. Quantitative feeding and transfer: During the rotation of the left transfer shaft (508), the transfer shaft (508) synchronously drives the short shaft (611) to rotate through the transmission cooperation of the second pulley (612) and the second belt (613). The short shaft (611) drives the cam (614) to rotate. The cam (614) rotates reciprocally to drive the handle movable frame (610) up and down. The handle movable frame (610) drives the toothed plate (615) to reciprocally engage with the second gear (604). When the toothed plate (615) descends and engages with the second gear (604), the second gear (604) drives the rotating shaft (603) to rotate. The rotating shaft (603) is extrusion-fitted with the card slot (608) through the inclined surface of the single-sided inclined block (606). Since the hollow shaft (601) is restricted by the anti-reverse cooperation of the ratchet (620) and the pawl (622), the rotating shaft (603) idles by itself. When the toothed plate (615) ascends and anti-engages with the second gear (604), the rotating shaft (603) drives the hollow shaft (601) to rotate through the contact cooperation between the flat surface of the single-sided inclined block (606) and the card slot (608). The hollow shaft (601) drives the material-supporting dial (602) to intermittently rotate equidistantly around. The intermittent equidistant rotation of several material-supporting dials (602) will intermittently and relatively quantitatively feed the stored material inside the storage bin (1) into the processing frame (3). Intermittent elastic material pressing: During the reciprocating descent of the handle movable frame (610), the cross plate (609) is synchronously driven to descend. The cross plate (609) drives the pressing frame (619) to elastically descend through the elastic cooperation of the storage cylinder (616), the telescopic rod (617) and the third return spring (618). The reciprocating descent of the pressing frame (619) elastically presses the plastic fed into the processing frame (3), so that the plastic is in close contact with the crushing cutter (404), accelerating the crushing. S4. Vibration-accelerated feeding: During the reciprocating lifting and lowering of the cross plate (609), the cross plate (609) synchronously drives the lifting plate (704) to lift the blanking plate (702). The lifting of the blanking plate (702) will increase the rotation angle and drop the accumulated material on the inclined surface downward.
