Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, in particular to a waste plastic processing and recycling system and a waste plastic processing and recycling method. Background Art

[0002] Plastic products are daily and industrial products made of plastic as the main raw material. Plastic products are often discarded after use. At the same time, some waste plastics are generated during the production process of plastic products. Waste plastics can be recycled and reused, so these waste materials need to be squeezed to facilitate centralized transportation and treatment.

[0003] The patent publication number of the existing patent application is: CN218256154U, and the publication date is January 10, 2023. The name of the patent is "A waste plastic recycling device in plastic product production". The patent includes a pad, a bin body is fixedly installed on the top of the pad, a crushing device is fixedly installed inside the bin body, and an adjustment component is arranged inside the bin body. A collecting box is movably installed on the top of the pad and on the left side of the bin body. The adjustment component includes a partition, which is fixedly installed inside the bin body and located below the crushing device. A driving motor is fixedly installed on the right side of the bin body, and two screws are rotatably connected to the right side of the inner wall of the bin body and located below the partition. The waste plastic recycling device in plastic product production can easily push the waste crushed by the crushing device into the collecting box through the adjustment component. When the plastic in the collecting box is full, the waste can also be squeezed. The capacity occupied by the compressed waste is reduced, thereby increasing the loading volume of the collecting box, thereby improving the efficiency of waste recycling.

[0004] The above application has shortcomings. If the plastic products are directly crushed before extrusion, if there are foreign objects in the plastic products, they will also be crushed, and it will be more difficult to clean after crushing and mixing. At the same time, if they are directly extruded without crushing, the impurities in the gaps cannot be completely cleaned out simply by flushing with a cleaning liquid. Moreover, when the waste plastics are completely squeezed, it is dangerous to remove them manually because the stamping parts are located above them. However, adding a driving part to push the materials will increase the operating costs. Summary of the invention

[0012] Preferably, a first transmission gear and a second transmission gear connected by a transmission belt are rotatably mounted on the outer support plate, the first transmission gear is meshed with the adjustment rack, and the second transmission gear is meshed with the inner wall of the lifting gear rack.

[0013] Preferably, a stop block is installed in the middle of the one-way lifting rod, and a groove for the stop block to move is provided on the abutting protrusion.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] See also Figure 1-9 The waste plastic processing and recycling system provided by the embodiment of the present invention includes a frame 1, in which a storage bin 2 is installed, and also includes a stamping mechanism 3, which is installed on the top of the frame 1, and its stamping part is located in the storage bin 2, and a lifting tray 4, which is located below the stamping mechanism 3. A transmission member 5 is installed between the stamping mechanism 3 and the lifting tray 4, and a pushing assembly 6 connected to the transmission member 5 is installed on the lifting tray 4. When the stamping mechanism 3 is pressed down, the lifting tray 4 is first forced to vibrate through the transmission member 5, and then the lifting tray 4 stops vibrating and is forced to descend. When the stamping mechanism 3 rises, the height of the lifting tray 4 is fixed and the pushing assembly 6 is driven to discharge the compressed waste.

[0037] Specifically, the frame 1 is sleeved on the outside of the storage bin 2, and the storage bin 2 is opened up and down. The stamping part of the stamping mechanism 3 is located at the top opening in the storage bin 2, and the lifting tray 4 is located in the bottom opening of the storage bin 2. When the stamping part in the stamping mechanism 3 rises, the waste is poured through the opening above the storage bin 2, and the waste entering the storage bin 2 will be accumulated above the lifting tray 4. At this time, the stamping mechanism 3 is controlled to descend. Before the waste is pressurized, the lifting tray 4 is forced to vibrate up and down through the transmission member 5, so that the gap between the wastes becomes larger, and the wastes collide and rub against each other, which can improve the cleaning effect when the waste needs to be rinsed and avoid excessive impurities in the compressed waste. When the punching part is completely in contact with the waste material and applies pressure to it, the lifting tray 4 will gradually descend under the action of pressure until it drops to the lowest height, that is, the position of the opening below the storage bin 2. During this process, the lifting tray 4 no longer vibrates continuously, allowing the punching mechanism 3 to stably squeeze the waste material. After the waste material is compressed, when the punching mechanism 3 rises, the position of the lifting tray 4 will be maintained for a period of time, and then the transmission part 5 will be used to drive the pushing assembly 6 to push the compressed waste material out of the bin. No additional power source is required for driving during the whole process. After the punching mechanism 3 rises to a suitable height, the height of the lifting tray 4 will be reset, so that it is convenient for it to support the waste material entering the storage bin 2.

[0038] Compared with the prior art, the embodiment of the present invention sets a transmission part 5 to allow the lifting tray 4 to swing up and down when the stamping mechanism 3 is pressed down, so that the gap between the waste plastics can be enlarged before extrusion, and the plastics will also rub and collide with each other, which can improve the cleaning effect when flushing them, and can also make the waste material evenly distributed under the stamping mechanism 3 through vibration. When the stamping mechanism 3 completely squeezes the waste material, the lifting tray 4 will stop vibrating and descend under the action of pressure, so that the completely compressed waste material reaches the corresponding height, so that the stamping mechanism 3 drives the pushing assembly 6 to push the compressed waste out after rising, avoiding the staff from unloading under the stamping mechanism 3, reducing safety hazards, and no need to install additional driving parts to complete the pushing.

[0039] In a further embodiment of the present invention, the punching mechanism 3 includes a cylinder 301 fixed to the top of the frame 1, and the open end of the cylinder 301 is fixedly connected to a connecting seat, and a number of fasteners are installed between the connecting seat and the top of the frame 1, and a punch rod 302 is sleeved in the cylinder 301, and a pressure plate 303 is installed at the bottom of the punch rod 302. Specifically, the punch rod 302 and the pressure plate 303 are both in the frame 1. When the punch rod 302 is extended, the pressure plate 303 is brought downward into the storage bin 2, and the four inner walls of the storage bin 2 are in contact with and fit the edges of the pressure plate 303 to prevent smaller waste materials from reaching the top of the pressure plate 303 through the gap between the pressure plate 303 and the inner wall of the storage bin 2 during the extrusion process of the pressure plate 303. The pressure plate 303 can comprehensively compress the waste materials in the storage bin 2, and the height of the pressure plate 303 can be flexibly adjusted.

[0040] In a further embodiment of the present invention, the lifting tray 4 is located in the storage bin 2, and a pair of inner support plates 401 are installed at the bottom of the lifting tray 4, and the inner support plates 401 are provided with outer support plates 402. The outer support plates 402 and the inner support plates 401 are elastically connected, and a lifting spring 407 is installed between the outer support plates 402 and the inner support plates 401, and the bottom of the outer support plate 402 is fixed to the frame 1. Specifically, by putting the inner support plates 401 in the outer support plates 402, the lifting tray 4 can be made to sink vertically when it is pressurized, so that the lifting tray 4 can move downward to a suitable position with the gradually compressed waste to facilitate unloading. At the same time, the lifting spring 407 will push the inner support plate 401 entering the outer support plate 402 upward, so that when the compressed waste is removed from the stamping mechanism 3 and the lifting tray 4 is lifted again and enters the storage bin 2.

[0041] In a further embodiment of the present invention, one side of the punch rod 302 is fixedly connected to an abutment frame 304, the transmission member 5 includes a push-pull frame 501 elastically mounted on the back of the frame 1, and a plurality of limit frames 101 are fixedly connected to the frame 1, the push-pull frame 501 is horizontally slidably connected to the limit frame 101, and a compression spring 102 is installed between the two, the abutment frame 304 is in an inverted U shape, one end is fixed to the rod head of the punch rod 302, and the other end protrudes outward and abuts against the push-pull frame 501, and one side of the push-pull frame 501 is provided with an abutment rack 502 and an abutment groove that abut against the abutment frame 304 from top to bottom. 503 and abutment protrusion 504, abutment groove 503 and abutment protrusion 504 are connected together, an insert plate 505 is installed between the push-pull frame 501 and the outer support plate 402, the insert plate 505 passes through the outer support plate 402 and is inclined against one side of the bottom of the inner support plate 401, the insert plate 505 is penetrated by an inclined groove 509, and the push-pull frame 501 is fixedly connected with an insert rod 510 that passes through the inclined groove 509. When the push-pull frame 501 moves forward and backward, the insert plate 505 drives the inner support plate 401 to move up and down. Specifically, under the action of the compression spring 102, the push-pull frame 501 always abuts against the abutment When the punch rod 302 moves down with the abutting frame 304, the abutting frame 304 abuts against the abutting rack 502, the abutting groove 503 and the abutting protrusion 504 in sequence. When the abutting frame 304 abuts against the abutting rack 502 and moves down, the push-pull frame 501 moves back and forth under the bidirectional force of the abutting rack 502 and the compression spring 102. When the push-pull frame 501 moves back and forth, the cooperation between the insertion rod 510 and the inclined groove 509 forces the plug plate 505 to move horizontally on the outer support plate 402. When the plug plate 505 is inserted, it gradually pushes up the inner support plate 401. During the extraction process, the inner support plate 401 is reset and lowered, and the up and down vibration of the lifting tray 4 is controlled by the change in the position of the plug plate 505. When the bottom end of the abutting frame 304 abuts against the abutting groove 503, the push-pull frame 501 moves forward a distance under the action of the compression spring 102, so that the plug plate 505 no longer abuts against and blocks the inner support plate 401, so that the punching mechanism 3 can compress the waste material and first press the lifting tray 4 to a corresponding height through the waste material, which is convenient for unloading and avoids the plug plate 505 used to make the lifting tray 4 vibrate to block the lifting tray 4 from descending.

[0042] In a further embodiment of the present invention, the pushing assembly 6 includes a pushing rack 601 slidably mounted on the top surface of the lifting tray 4, one end of the pushing rack 601 is against the inner wall of the storage bin 2, a driving gear 602 connected to the pushing rack 601 is rotatably mounted on one side of the inner support plate 401, an adjusting gear 606 coaxially connected to the driving gear 602 is mounted in the inner support plate 401, a transmission rack 608 meshing with the adjusting gear 606 is provided at the bottom of the pushing rack 601, an adjusting rack 603 matching the driving gear 602 is vertically slidably mounted on one side of the outer support plate 402, a receiving groove 506 is opened in the plug plate 505, and an elastic connector 7 connected to the adjusting rack 603 is horizontally slidably mounted on the inner side of the receiving groove 506, The elastic connector 7 is located on the side of the adjusting rack 603 facing away from the teeth, and the elastic connector 7 is vertically slidably connected to the adjusting rack 603. The bottom of the push-pull frame 501 is also fixedly connected to a push rod 511 for pressing the adjusting rack 603. A pair of lifting gear racks 604 are vertically slidably installed on the back of the frame 1. A one-way lifting rod 8 connected to a pair of lifting gear racks 604 is slidably installed in the abutment protrusion 504. When the abutment frame 304 moves up along the abutment protrusion 504, the lifting gear rack 604 is transmission-connected with the adjusting rack 603. The lifting gear rack 604 is driven by lifting the one-way lifting rod 8 to move up, thereby forcing the adjusting rack 603 to move down. Specifically, when the abutment frame 304 moves down along the abutment groove 503, the lifting tray 4 and the inner support During the descent of plate 401, driving gear 602 will abut against adjusting gear 606. Since one end of pushing rack 601 always abuts against the inner wall of storage bin 2, driving gear 602 will not rotate even if it abuts against adjusting rack 603. Because pushing rack 601 cannot move in the opposite direction toward the discharging place, adjusting gear 606 will be forced to move in the discharging direction until lifting tray 4 drops to the lowest height. Adjusting gear 606 will also intermittently mesh with driving gear 602 under the action of elastic abutment, so as to ensure that when lifting tray 4 reaches the height where it cannot continue to descend, adjusting gear 606 will mesh with driving gear 602. Then, when abutment rack 304 continues to descend against abutment protrusion 504, pushing rack 304 will abut against abutment protrusion 504. The pulling frame 501 will retreat backward, allowing the supporting rod 511 that originally did not abut the adjusting rack 603 to gradually press against the adjusting rack 603, so that the adjusting rack 603 and the driving gear 602 are always in contact with each other. When the waste is compressed, the punching rod 302 in the punching mechanism 3 rises with the pressing plate 303. At this time, the abutting frame 304 pulls the one-way lifting rod 8 upward, and lifts the lifting gear frames 604 on both sides by the belt lifting rod. The lifting gear frames 604 drive the adjusting rack 603 to move downward, thereby driving the driving gear 602 and the adjusting gear 606 to rotate in the other direction at the same time, so that the pushing frame 601 moves in the discharging direction to push out the compressed waste. The compressed waste is pushed out without the need to use an independent driving source, thereby reducing the cost of processing and maintenance.

[0043] In a further embodiment of the present invention, a first transmission gear 403 and a second transmission gear 405 connected by a transmission belt 404 are rotatably installed on the outer support plate 402, the first transmission gear 403 is meshed with the adjusting rack 603, and the second transmission gear 405 is meshed with the inner wall of the lifting rack 604. Specifically, when the lifting rack 604 is lifted, the second transmission gear 405 is driven to rotate, and the first transmission gear 403 rotates in the same direction with the second transmission gear 405 through the transmission belt 404, and then the first transmission gear 403 is used to drive the adjusting rack 603 to descend, and the reverse movement of the adjusting rack 603 and the lifting rack 604 is used to control the timing of moving out of the push rack 601, and the push rack 601 will only push out the pressed waste after the pressure plate 303 moves to a suitable height, so as to avoid the push rack 601 moving outward during the process of squeezing the waste by the pressure plate 303, thereby ensuring the smoothness of the entire operation processing and also avoiding damage to the parts after forced operation.

[0044] In a further embodiment of the present invention, a stopper 801 is installed in the middle of the one-way lifting rod 8, a groove 507 for the stopper 801 to move is provided on the abutting protrusion 504, a torsion spring sleeve 802 is installed at both ends of the one-way lifting rod 8, a rotary torsion spring (not shown in the figure) connected to the one-way lifting rod 8 is installed in the torsion spring sleeve 802, the torsion spring sleeve 802 is slidably connected to the top of the inner wall of the lifting gear rack 604, and a limit stopper abutting against the top of the inner wall of the lifting gear rack 604 is fixedly connected to the outer side of the one-way lifting rod 8 The one-way lifting rod 8 has a plurality of guide grooves 508 on both sides of the groove 507, and the top of the guide groove 508 has a bent section. Specifically, under the action of the rotary torsion spring, when the abutting frame 304 descends and abuts against the abutting protrusion 504, the end of the abutting block 801 on the one-way lifting rod 8 will expose the groove 507. When the abutting frame 304 moves from top to bottom along the abutting protrusion 504 and abuts against the abutting block 801, the one-way lifting rod 8 will be forced to rotate to allow the abutting block 801 to avoid the abutting block 801. The support frame 304 is connected to the support frame 304. After the bottom end of the support frame 304 moves to the bottom of the stop block 801, the one-way lifting rod 8 rotates and resets under the action of the rotary torsion spring, and the end of the stop block 801 re-exposes the groove 507. When the support frame 304 moves from bottom to top, it will still abut against the stop block 801 on the one-way lifting rod 8. However, when the stop block 801 is lifted from bottom to top, the limit block 803 on the one-way lifting rod 8 will abut against the lifting gear frame 604 to prevent the one-way lifting rod 8 from rotating, thereby making the support frame 304 When moving upward, the one-way lifting rod 8 can be lifted along the guide groove 508, so that the one-way lifting rod 8 pulls up the lifting gear frame 604 to drive the pusher frame 601 to be pushed out. At the same time, when the one-way lifting rod 8 continues to move upward along the guide groove 508 to the bending section in the guide groove 508, the distance between the abutting frame 304 and the one-way lifting rod 8 gradually becomes farther, until the abutting frame 304 can release the one-way lifting rod 8, so that the one-way lifting rod 8 can be reset and lowered, so that the pusher frame 601 can be reset in time after the compressed waste is removed.

[0045] In a further embodiment of the present invention, the elastic connector 7 includes a first slider 701 horizontally slidably installed on one side of the accommodating groove 506, the first slider 701 is horizontally movable with a connecting rod 702, one end of the connecting rod 702 is fixedly connected to the second slider 703, a slide groove 605 adapted to the second slider 703 is vertically opened on the adjusting rack 603, a top spring 704 is installed between the first slider 701 and the second slider 703, a return spring 705 is fixedly connected in the slide groove 605, and the two ends of the return spring 705 are respectively fixed to the second slider 703 and the top of the inner wall of the slide groove 605. Specifically, by adding a top spring 704 between the first slider 701 and the second slider 703, the horizontal movement of the insert plate 505 and the up and down movement of the adjusting rack 603 itself can be affected while pushing the adjusting rack 603, and the added return spring 704 can automatically reset and move upward after the adjusting rack 603 is lowered, so that the pushing assembly 6 can continuously push the compressed material.

[0046] In a further embodiment of the present invention, a socket 406 compatible with the plug plate 505 is horizontally opened on the inner support plate 401. When the abutment frame 304 contacts the abutment protrusion 504, the plug plate 505 is inserted into the socket 406. Specifically, when the lifting tray 4 moves to the lowest position, the plug plate 505 on the outer support plate 402 and the socket 406 on the inner support plate 401 are at the same level. When the abutment frame 304 abuts against the abutment protrusion 504, as the push-pull frame 501 moves backward, the plug plate 505 is completely inserted into the socket 406, making the outer support plate 402 and the inner support plate 401 more stable, avoiding the lifting tray 4 from being lifted when the pressure plate 303 applies the maximum pressure, thereby ensuring the compression effect.
