Description

Technical Field

[0001] This invention relates to the field of plastic bottle crushing and recycling technology, specifically to an integrated equipment for removing labels and crushing waste plastic bottles. Background Technology

[0002] The integrated label removal and crushing equipment for waste plastic bottles is a type of mechanical equipment specifically designed for processing waste plastic bottles. Its main function is to simultaneously remove labels and crush waste plastic bottles in a continuous, automated process, enabling the plastic bottles to be further processed and recycled.

[0003] A waste plastic bottle crushing device disclosed in existing patent number CN110202720A includes a crushing box, a feeding box, a material straightening mechanism, a cutting mechanism, and a petal cutting mechanism. The bottom of the feeding box and the top of the crushing box are detachably installed by bolts. The material straightening mechanism is located in the inner cavity of the feeding box. The cutting mechanism is installed in the inner cavity of the crushing box. The petal cutting mechanism is located inside the cutting mechanism. This waste plastic bottle crushing device adopts a crushing method of cutting from the middle and then continuously pushing to both sides, so as to separate and crush the bottle body and the bottle mouth separately, avoiding the excessive force required to crush the harder bottle mouth, which would affect the normal crushing of the bottle body.

[0004] Although the above-mentioned crushing method uses a method of cutting from the middle and then continuously advancing to both sides to separate and crush the bottle body and bottle mouth separately, after the waste plastic bottle is crushed, due to some factors (the size of the crushed plastic fragments is uneven, and some larger fragments may have part of the label wrapped around them, so the label was not fully exposed and removed during the crushing process), the crushed plastic fragments still have labels remaining on them. The residual labels not only reduce the purity of the plastic fragments and affect their subsequent recycling, but also cause a decline in product quality during the recycled plastic production process, resulting in color differences and impurities. Moreover, in order to remove the residual labels, additional cleaning and sorting steps are required, increasing recycling costs.

[0005] Therefore, this invention proposes an integrated equipment for removing labels and crushing waste plastic bottles to solve the above problems. Summary of the Invention

The label separation mechanism is used to adsorb and separate the labels from the crushed plastic bottle fragments.

[0011] As a further aspect of the present invention: a collection box is installed on both sides of the negative pressure adsorption machine, and a diversion frame is provided above each collection box, and the diversion frame is fixedly connected to the inner side wall of the crushing box.

[0012] As a further aspect of the present invention: a cleaning plate is attached to the upper surface of the negative pressure adsorption machine, and a moving block is fixedly connected to the side of the cleaning plate near the horizontal groove, and the moving block is slidably connected in the horizontal groove.

[0013] As a further aspect of the present invention: a threaded rod is threadedly connected to the moving block, the threaded rod is located in the transverse groove, one end of the threaded rod is rotatably connected to the crushing box, and a first drive motor is fixedly connected to one end of the threaded rod through the crushing box, the first drive motor being fixedly connected to the side wall of the crushing box.

[0014] As a further aspect of the present invention: the anti-clogging mechanism includes a second drive motor, which is fixedly connected to the side wall of the crushing box. The output end of the second drive motor is fixedly connected to a rotating shaft, which is rotatably connected to the crushing box. A fixing plate is fixedly connected in an annular shape at equal intervals on the outer surface of the rotating shaft inside the crushing box. The fixing plate is located between the inclined plate and the negative pressure adsorbent.

[0015] As a further aspect of the present invention: the anti-clogging mechanism further includes a connecting shaft, which is rotatably connected to the crushing box. Both the outer surfaces of the connecting shaft and the rotating shaft are fixedly connected to pulleys outside the crushing box, and a belt is sleeved between the outer surfaces of the two pulleys.

[0016] As a further embodiment of the present invention: the connecting shaft is fixedly connected to a lever inside the crushing box, and a lever is fixedly connected to the side of the lever away from the connecting shaft. A first frame is sleeved on the outer surface of the lever, and the lever is slidably connected to the first frame. Slider blocks are symmetrically fixedly connected to the side of the first frame near the inner wall of the crushing box, and the slider blocks are all horizontally slidably connected to the inner wall of the crushing box.

[0017] As a further aspect of the present invention: a connecting plate is symmetrically and fixedly connected to the side of the first frame away from the slider, and a second frame is fixedly connected between the two connecting plates on the side away from the first frame.

The pusher plates are all attached to the upper end face of the inclined plate, and the inclination angles of the first and second sliding grooves are the same as the inclination angle of the inclined plate.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides an integrated equipment for removing labels and crushing waste plastic bottles, which has the following beneficial effects:

[0021] 1. The set-in label separation mechanism for crushed materials allows the crushed materials to fall onto the surface of the negative pressure adsorption machine. The lightweight labels are adsorbed by the negative pressure adsorption principle, causing the crushed plastic bottles to fall into the collection box. This not only effectively removes residual labels from the crushed plastic fragments, significantly improving their purity, but also reduces color differences and impurities in subsequent recycled plastic production, improving the quality of recycled plastic products and enhancing their market competitiveness, thus increasing their value in subsequent recycling. Furthermore, the negative pressure adsorption machine quickly and effectively separates labels and plastic fragments, reducing the subsequent processing problems caused by label residue, improving the efficiency of the entire recycling process, eliminating the need for additional cleaning and sorting steps, reducing recycling costs, and increasing recycling efficiency.

[0022] 2. The first drive motor, threaded rod, and moving block drive the cleaning plate to move horizontally against the surface of the negative pressure adsorption machine, pushing the labels adsorbed on the surface of the negative pressure adsorption machine into the collection boxes on both sides. This not only effectively removes the labels adsorbed on the surface, but is also more efficient than manual cleaning, and can quickly complete the cleaning work. Moreover, the cleaning plate can closely adhere to the surface of the negative pressure adsorption machine during the movement, ensuring that the labels are completely removed and avoiding label residue problems caused by incomplete cleaning. This allows the negative pressure adsorption machine to continuously adsorb and separate the labels from broken plastic bottles.

[0023] 3. Through the designed anti-clogging mechanism, during the label separation process of plastic bottle fragments falling onto the negative pressure adsorption machine, the plastic bottle fragments are intermittently and quantitatively added to the surface of the negative pressure adsorption machine. This not only avoids the problems of incomplete label separation or overloading of the negative pressure adsorption machine caused by adding too many plastic bottle fragments at once, thus significantly improving the efficiency and quality of label separation, but also helps ensure that each plastic bottle fragment receives sufficient label separation processing on the negative pressure adsorption machine, thereby improving the purity and quality of the final product. In subsequent plastic bottle fragment recycling plastic production, it can further effectively reduce the occurrence of color difference and impurities, and enhance the market competitiveness of the product.

[0024] 4. Through the set pulleys, belts, connecting shafts, deflectors, levers, first frame, slide plate, connecting plate, second frame, connecting column, horizontal plate, and moving plate, the broken plastic bottle fragments can be intermittently conveyed to the surface of the negative pressure adsorption machine. At the same time, the pusher plate and deflector plate are driven to move synchronously back and forth on the upper surface of the inclined plate. This deflects the plastic bottle fragments that fall on the upper surface of the inclined plate. This not only deflects the broken plastic bottle fragments in advance, separating the plastic bottle fragments from the labels, thus significantly improving the separation efficiency of the subsequent negative pressure adsorption machine, reducing label residue, and improving the purity of the plastic fragments, but also pushes the plastic bottle fragments accumulated in the discharge trough, helping to maintain the smooth flow of plastic bottle fragments and reducing plastic bottle fragment separation failures and downtime caused by blockages.

[0038] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] This embodiment describes an integrated equipment for removing labels and crushing waste plastic bottles, such as... Figure 1 - Figure 8As shown, the device includes a crushing box 1, a collection box 2 that is slidably connected to the lower end of the crushing box 1, crushing rollers 3 that are symmetrically rotatably connected inside the crushing box 1, a first chute 6 and a second chute 7 that are provided on both sides inside the crushing box 1, and a transverse groove 8 that is provided inside the crushing box 1. It also includes a crushed material label separation mechanism and an anti-clogging mechanism. The crushed material label separation mechanism includes an inclined plate 403 and a negative pressure adsorption machine 404. The inclined plate 403 is fixedly connected to the inner wall of the crushing box 1, and the negative pressure adsorption machine 404 is close to the lower end of the inclined plate 403. The negative pressure adsorption machine 404 is fixedly connected to the inner wall of the crushing box 1 and is located below the transverse groove 8. A limit frame 406 is provided directly above the negative pressure adsorption machine 404, and a discharge chute 408 is provided between the limit frame 406 and the inclined plate 403. The crushed material label separation mechanism is used to adsorb and separate the labels inside the crushed plastic bottle fragments.

[0040] In this embodiment, as Figure 3 As shown, collection boxes 405 are installed on both sides of the negative pressure adsorption machine 404, and diversion racks 407 are installed above each collection box 405. The diversion racks 407 are fixedly connected to the inner wall of the crushing box 1. The diversion racks 407 can prevent plastic bottle fragments from falling directly into the collection box 405.

[0041] In this embodiment, as Figure 5 As shown, a cleaning plate 409 is attached to the upper surface of the negative pressure adsorption machine 404. A moving block 410 is fixedly connected to the side of the cleaning plate 409 near the horizontal groove 8. The moving block 410 is slidably connected in the horizontal groove 8. When the moving block 410 slides in the horizontal groove 8, it can drive the cleaning plate 409 to move synchronously on the surface of the negative pressure adsorption machine 404, so that the cleaning plate 409 cleans the surface of the negative pressure adsorption machine 404.

[0042] In this embodiment, as Figure 4 and Figure 5 As shown, a threaded rod 402 is threadedly connected to the movable block 410. The threaded rod 402 is located in the transverse groove 8. One end of the threaded rod 402 is rotatably connected to the crushing box 1. A first drive motor 401 is fixedly connected to one end of the threaded rod 402 through the crushing box 1. The first drive motor 401 is fixedly connected to the side wall of the crushing box 1. When the first drive motor 401 drives the threaded rod 402 to rotate, the threaded connection between the threaded rod 402 and the movable block 410 allows the movable block 410 to slide horizontally in the transverse groove 8, from one end of the transverse groove 8 to the other end.

[0043] In existing technologies, after the waste plastic bottles are crushed, due to various factors (the plastic fragments are not uniform in size, and some larger fragments may have partially covered the labels, preventing the labels from being fully exposed and removed during the crushing process), labels remain on the crushed plastic fragments. These residual labels not only reduce the purity of the plastic fragments, affecting their subsequent recycling, but also lead to a decline in product quality during the recycled plastic production process, resulting in color differences and impurities. Furthermore, removing the residual labels requires additional cleaning and sorting steps, increasing recycling costs. In contrast, existing technologies allow the crushed material to fall onto the surface of a 404 negative pressure adsorption machine, where it is absorbed and processed through a negative pressure system. The pressure adsorption principle adsorbs lightweight labels, causing broken plastic bottles to fall into collection box 2. This not only effectively removes residual labels from broken plastic fragments, significantly improving their purity, but also reduces color differences and impurities in subsequent recycled plastic production, improving the quality of recycled plastic products and enhancing their market competitiveness, thus increasing their value in subsequent recycling. Furthermore, the negative pressure adsorption machine 404 quickly and effectively separates labels and plastic fragments, reducing subsequent processing problems caused by label residue, improving the efficiency of the entire recycling process, eliminating the need for additional cleaning and sorting steps, reducing recycling costs, and increasing recycling efficiency.

[0044] At other levels, this embodiment also provides an anti-clogging mechanism for controlling the amount of broken material falling onto the surface of the negative pressure adsorption machine 404, such as... Figure 1 , Figure 2 , Figure 6 - Figure 8 As shown, the anti-clogging mechanism includes a second drive motor 501, which is fixedly connected to the side wall of the crushing box 1. The output end of the second drive motor 501 is fixedly connected to a rotating shaft 507, which is rotatably connected to the crushing box 1. The outer surface of the rotating shaft 507 is circumferentially and equidistantly connected to a fixing plate 508 inside the crushing box 1. The fixing plate 508 is located between the inclined plate 403 and the negative pressure adsorbent.

[0045] In this embodiment, as Figure 6 and Figure 7 As shown, the anti-clogging mechanism also includes a connecting shaft 511, which is rotatably connected to the crushing box 1. Both the connecting shaft 511 and the outer surface of the rotating shaft 507 are fixedly connected to pulleys 512 outside the crushing box 1. A belt 502 is sleeved between the outer surfaces of the two pulleys 512. When the rotating shaft 507 rotates, the connecting shaft 511 can be driven to rotate synchronously through the transmission connection between the pulleys 512 and the belt 502.

[0046] In this embodiment, as Figure 6 and Figure 7As shown, a lever 513 is fixedly connected to the connecting shaft 511 inside the crushing box 1. A lever 514 is fixedly connected to the side of the lever 513 away from the connecting shaft 511. A first frame 509 is sleeved on the outer surface of the lever 514. The lever 514 is slidably connected inside the first frame 509. Slider 510s are symmetrically fixedly connected to the side of the first frame 509 near the inner wall of the crushing box 1. The sliders 510 are all horizontally slidably connected to the inner wall of the crushing box 1. When the connecting shaft 511 drives the lever 513 to rotate, the connecting shaft 511 will push the lever 514 to rotate synchronously. At the same time, the lever 514 slides up and down inside the first frame 509. At this time, the lever 514 will push the first frame 509 to move and slide through the sliders 510 connected to the side wall of the first frame 509 and the crushing box 1, so that the first frame 509 moves horizontally back and forth on the inner wall of the crushing box 1.

[0047] In this embodiment, as Figure 6 and Figure 7 As shown, a connecting plate 506 is symmetrically fixedly connected to the side of the first frame 509 away from the slider 510. A second frame 516 is fixedly connected between the two connecting plates 506 away from the first frame 509. A connecting column 517 is vertically slidably connected inside the second frame 516. A horizontal plate 515 is fixedly connected to the end of the connecting column 517 away from the connecting plate 506. A pusher plate 503 is fixedly connected to the side of the horizontal plate 515 near the negative pressure adsorption machine 404. The pusher plate 503 is slidably connected between two second slide grooves 7. When the first frame 509 moves horizontally back and forth, the connecting plate 506 can drive the second frame 516 to move synchronously. The second frame 516 will then move the vertically slidably connected connecting column 517 inside, causing the horizontal plate 515 to move synchronously. The movement causes the horizontal plate 515 to pull the pusher plate 503 to slide horizontally back and forth in the second slide groove 7 along with the first frame 509, pushing the plastic bottle fragments at the discharge groove 408 to prevent the plastic bottle fragments from accumulating at the discharge groove 408. When the horizontal plate 515 and the pusher plate 503 move along the path of the second slide groove 7, the height of the horizontal plate 515 and the pusher plate 503 will change synchronously due to the inclination angle of the second slide groove 7. At this time, the connecting column 517 connected to the side wall of the horizontal plate 515 will move up and down synchronously inside the second frame 516 to adapt to the change in height of the horizontal plate 515 and the pusher plate 503, so that the second frame 516 can still push the horizontal plate 515 and the pusher plate 503 to move through the connecting column 517.

[0048] In this embodiment, as Figure 6 and Figure 8As shown, a movable plate 504 is fixedly connected to the end of the horizontal plate 515 away from the pusher plate 503. The movable plate 504 is slidably connected between two first slide grooves 6. A pusher plate 505 is fixedly connected at equal intervals to the lower end face of the movable plate 504. The pusher plates 505 are all attached to the upper end face of the inclined plate 403. The inclination angles of the first slide grooves 6 and the second slide grooves 7 are the same as the inclination angle of the inclined plate 403. When the horizontal plate 515 moves horizontally, it can drive the movable plate 504 to move horizontally back and forth along the path of the first slide groove 6, and make the pusher plate 505 connected to the lower end face of the movable plate 504 push the plastic bottle fragments on the surface of the inclined plate 403 back and forth, promoting the separation of the plastic bottle fragments and label fragments.

[0049] Compared to existing technologies, this method allows for intermittent and quantitative label separation of plastic bottle fragments falling onto the negative pressure adsorption machine 404. This not only avoids incomplete label separation or overloading of the machine caused by adding too many fragments at once, significantly improving the efficiency and quality of label separation, but also ensures that each fragment receives sufficient label separation on the machine. This improves the purity and quality of the final product and further reduces color differences and impurities in subsequent recycled plastic production, enhancing the product's market competitiveness.

[0050] The overall working process and principles involved in the above embodiments are as follows:

[0051] During the crushing process of plastic bottles, the plastic bottles are placed into the crushing chamber 1. The crushing rollers 3, which are symmetrically connected inside the crushing chamber 1, rotate to crush the plastic bottles. The crushed plastic bottle fragments fall onto the upper surface of the inclined plate 403 inside the crushing chamber 1. Due to the inclination of the inclined plate 403, the plastic bottle fragments slide along the upper surface of the inclined plate 403. While the crushing rollers 3 are rotating and crushing the plastic bottles, the operator simultaneously turns on the second drive motor 501, which drives the rotating shaft 507 connected to the output end of the second drive motor 501 to rotate on the upper surface of the crushing chamber 1. The shaft rotates because pulleys 512 are connected to the outer surfaces of both the rotating shaft 507 and the connecting shaft 511. A belt 502 is fitted between the outer surfaces of the pulleys 512. Therefore, as the rotating shaft 507 rotates, the connecting shaft 511 can be driven to rotate synchronously through the pulleys 512 and the belt 502. This causes the dial plate 513 connected to one end of the connecting shaft 511 inside the crushing box 1 to rotate synchronously. This causes the lever 514 connected to the side wall of the dial plate 513 to rotate around the connecting shaft 511. Since the lever 514 is slidably connected inside the first frame 509, the first frame 509 is connected to the slider 510. The horizontal sliding connection is attached to the inner wall of the crushing chamber 1. Therefore, when the lever 514 rotates with the lever plate 513 and slides vertically inside the first frame 509, it can move the first frame 509 horizontally back and forth on the inner wall of the crushing chamber 1. When the first frame 509 moves horizontally, it will drive the second frame 516 to move horizontally synchronously through the connecting plate 506 symmetrically connected to the side wall. At this time, the second frame 516 will drive the horizontal plate 515 to move horizontally back and forth with the first frame 509 through the connecting column 517 slidably connected inside. Since the horizontal plate 515 is fixed on both sides respectively... The device is equipped with a pusher plate 503 and a moving plate 504, both of which are horizontally slidably connected to the inner wall of the crushing box 1. Therefore, as the horizontal plate 515 moves back and forth, it can pull the moving plate 504 and the pusher plate 503 to move horizontally in sync. During the movement, the pusher plate 503 will push the plastic bottle fragments located at the discharge chute 408 away from the discharge chute 408, avoiding the situation where too many plastic bottle fragments at the discharge chute 408 cause blockage. This helps to maintain the smooth flow of plastic bottle fragments and reduce plastic bottle fragment separation failures and downtime caused by blockage.

[0052] During the reciprocating movement of the moving plate 504, the moving plate 504 will drive the material feeding plate 505, which is fixedly connected at equal intervals on the lower end face, to move horizontally and reciprocally on the surface of the inclined plate 403. This will move the plastic bottle fragments that fall onto the surface of the inclined plate 403, causing the plastic bottle fragments and labels to separate. This will significantly improve the separation efficiency of the subsequent negative pressure adsorption machine 404, reduce label residue, and improve the purity of the plastic fragments.

[0053] During the process of the feeding plate 505 and the pushing plate 503 moving the plastic bottle fragments, as the rotating shaft 507 rotates, the rotating shaft 507 will drive the fixed plates 508, which are equidistantly fixed to the outer surface, to rotate synchronously. Since the fixed plates 508 are located between the inclined plate 403 and the negative pressure adsorption machine 404, when the plastic bottle fragments on the surface of the inclined plate 403 fall through the discharge chute 408, they will fall into the space between the two adjacent fixed plates 508. As the fixed plates 508 rotate, the two adjacent fixed plates 508 will intermittently and quantitatively deliver the collected plastic bottle fragments to the top of the negative pressure adsorption machine 404. After the plastic bottle fragments fall to the top of the negative pressure adsorption machine 404, because the negative pressure adsorption machine 404 is inclined, the plastic bottle fragments will roll downwards from the higher part of the surface of the negative pressure adsorption machine 404, and finally fall to the lower part. Inside the collection box 2, the lightweight labels mixed in with the plastic bottle fragments are attracted by the negative pressure adsorption machine 404 and adhere to the surface of the negative pressure adsorption machine 404, thus separating the labels from the plastic bottle fragments. This not only effectively removes the labels remaining on the broken plastic fragments, significantly improving the purity of the plastic fragments, but also reduces color difference and impurities in the subsequent recycled plastic production process, improving the quality of recycled plastic products and enhancing their market competitiveness, thereby increasing their value in subsequent recycling. Moreover, the use of the negative pressure adsorption machine 404 to quickly and effectively separate labels and plastic fragments can reduce the subsequent processing problems of plastic bottle fragments caused by label residue, improve the efficiency of the entire recycling process, eliminate the need for additional cleaning and sorting steps, reduce recycling costs, and improve recycling efficiency.

[0054] When it is necessary to clean the labels on the surface of the negative pressure adsorption machine 404, the operator can turn off the second drive motor 501, stop the rotation of the rotating shaft 507, and pause the conveying of plastic bottle fragments by the fixed plate 508 connected to the outer surface of the rotating shaft 507. Then, the first drive motor 401 is turned on, driving the threaded rod 402 to rotate. Through the threaded connection between the threaded rod 402 and the moving block 410, the moving block 410 can slide inside the transverse groove 8 connected to the inner wall of the crushing box 1, sliding from one side of the transverse groove 8 to the other. At this time, since the cleaning plate 409 is connected to the side wall of the moving block 410 and adheres to the surface of the negative pressure adsorption machine 404, the labels are cleaned. During the sliding process of the moving block 410, it can drive the cleaning plate 409 to move synchronously against the surface of the negative pressure adsorption machine 404, pushing the label fragments adsorbed on the surface of the negative pressure adsorption machine 404 from one side to the other and falling into the collection box 405 installed on the side wall of the negative pressure adsorption machine 404. This not only effectively removes the labels adsorbed on the surface, but is also more efficient than manual cleaning, and can quickly complete the cleaning work. Moreover, the cleaning plate 409 can closely adhere to the surface of the negative pressure adsorption machine 404 during the movement, ensuring that the labels are completely removed and avoiding label residue problems caused by incomplete cleaning, so that the negative pressure adsorption machine 404 can continuously adsorb and separate the broken plastic bottle labels.
