Description

Technical Field

[0001] This invention relates to the field of recycling technology, specifically to a device for recycling and reusing waste materials from masterbatch production. Background Technology

[0002] With the continuous development of the plastics industry, the amount of waste generated during the production of masterbatch, a key coloring material, including defective products, transitional materials, and scraps, is increasing daily. To achieve green production and resource conservation, recycling and reusing these wastes has become an industry consensus.

[0003] Patent publication number CN223442609U relates to the field of recycling technology and solves the current problem of inconvenience in retrieving sieved particles. It includes a processing box with a feed hopper fixedly connected to the top and a discharge frame fixedly connected to the bottom. A door is hinged to the outside of the processing box. The processing box contains a screening mechanism, including a feed frame fixed inside the box, a discharge frame fixedly connected to the bottom of the feed frame, a screening cylinder inside the processing box fitted around the discharge frame, a positioning groove at the bottom of the screening cylinder, and an inner plate fixedly connected inside the processing box. Two reinforcing rods are symmetrically fixedly connected between the inner plate and the discharge frame. A positioning block is provided on the inner plate and inserted into the positioning groove. This invention allows for the removal of particles from the screening cylinder, thus facilitating the retrieval of sieved particles.

[0004] The aforementioned solution, in traditional masterbatch waste recycling devices, typically uses fixed magnets to simply attract iron filings from the crushed waste. While this method can remove some metallic impurities, the fixed magnets limit the attraction range, making it difficult to cover all material on the conveyor belt. This results in incomplete iron filings removal, affecting the purity of the recycled material. A more significant problem is the continuous accumulation of iron filings on the magnet surface, causing magnetic attenuation, reduced efficiency, and frequent shutdowns for manual cleaning. This cumbersome cleaning process is prone to spillage and secondary pollution, increasing maintenance costs and impacting the cleanliness of the production environment and operational safety. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for recycling and reusing waste materials from masterbatch production, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste recycling and reuse device for masterbatch production, comprising a transport device and a working frame disposed on the surface of the transport device. The working frame includes a crushing device and a positioning frame. The positioning frame is fixed on the surface of the transport device. The crushing device is disposed on the top of the positioning frame and is used to crush the collected waste. The rotating shaft is connected to the rotating shaft of the transport device via a belt. The waste recycling and reuse device for masterbatch production further includes: a collection device disposed on the inner wall of the positioning frame for separating iron filings from the waste; a leveling device disposed on the inner wall of the positioning frame for leveling the crushed waste; and a control device disposed at the bottom of the crushing device for controlling the discharge of the crushed waste. The collecting device includes a rotating shaft rotatably embedded in the inner wall of the positioning frame, a rack sliding on the outer wall of the working frame, a sliding frame sliding on the inner wall of the positioning frame, a magnetic block sliding on the inner wall of the sliding frame, a fixing block fixed on the outer wall of the magnetic block, an outer frame fixed on the inner wall of the positioning frame, a collecting frame sliding on the inner wall of the outer frame, and a push block fixed on the surface of the outer frame. Half of the circumferential surface of the rotating shaft is provided with teeth. The rack includes upper teeth and lower teeth. The rack matches the teeth on the surface of the rotating shaft. The sliding frame is fixedly connected to the rack. A groove is opened on the outer wall of the positioning frame, and the collecting frame contacts the inner wall of the groove.

[0007] The collecting device also includes a sliding plate that slides on the surface of the outer frame, a connecting rod rotatably connected to the sliding plate, a push plate rotatably connected to the connecting rod, a scraper set at the bottom of the sliding plate, a fixing rod fixed to the surface of the outer frame, a sliding rod fixed to the outer wall of the scraper, a rotating block rotating on the outer wall of the sliding rod, and a blocking block fixed to the outer wall of the sliding rod. One end of the connecting rod is rotatably connected to the sliding plate, and the other end of the push plate is rotatably connected to the connecting rod. The outer wall of the sliding plate has a sliding groove, and the sliding rod contacts the inner wall of the sliding groove. The scraper moves and slides in connection with the sliding plate, and the other end of the scraper is slidably connected to the outer frame. The magnetic block reciprocates under the drive of the sliding frame, which can scan a larger area and adsorb more fully than a fixed magnet. The inclined design of the push block automatically lifts and releases iron filings, realizing the self-cleaning of the magnetic separation unit and avoiding the problem of magnetic attenuation caused by the accumulation of iron filings or the need for manual shutdown for cleaning.

[0008] The push block has an inclined surface on the side near the fixed block to facilitate downward movement of the fixed block. An elastic element is provided between the sliding plate and the outer frame to reset the sliding plate. A torsion spring is provided between the rotating block and the sliding rod to reset the rotating block. The fixed rod has an inclined surface on the side near the rotating block. An elastic element is provided between the sliding rod and the sliding plate to reset the sliding rod. The leveling device includes a connecting rod 1 fixed to the bottom of the sliding frame, a push plate disposed on the inner wall of the positioning frame, a connecting rod 2 rotatably connecting the push plate and the connecting rod 1, a sliding plate sliding on the inner wall of the positioning frame, and a connecting plate rotatably connecting the push plate and the sliding plate. The push plate is fixedly connected to the positioning frame, and the part connecting the push plate and the positioning frame is configured as a telescopic rod.

[0009] The leveling device also includes an outer rod sliding on the surface of the push plate, an inner rod sliding on the inner wall of the outer rod, a second connecting rod rotatably connecting the push plate and the inner rod, a smoothing plate sliding on the inner wall of the inner rod, and a second push plate disposed on the outer wall of the smoothing plate. One end of the second connecting rod is rotatably connected to the inner rod, and the other end of the second connecting rod is rotatably connected to the push plate. The reciprocating motion of the sliding frame serves as a power source, synchronously driving the material collection push plate and the leveling smoothing plate to move. The movement of these two components will quickly organize the scattered and unevenly thick fragments on the conveyor belt into a centrally located and uniformly thick material belt.

[0010] An elastic element is provided between the push plate and the positioning frame. The elastic element is provided to drive the push plate to reset. An elastic element is provided between the flat plate and the inner rod. The elastic element is provided to drive the flat plate to reset. The side of the push plate near the outer rod is set as an inclined surface.

[0011] The control device includes a rotating opening and closing plate at the bottom of the crushing device, a winding wheel disposed on the outer wall of the opening and closing plate, a connecting rod three sliding on the bottom of the opening and closing plate, a pulling rod connecting the connecting rod three and the winding wheel, a sliding rod sliding on the inner wall of the opening and closing plate, a locking key sliding on the inner wall of the opening and closing plate, a connecting rod three rotatably connecting the sliding rod and the locking key, and a push rod fixed on the outer wall of the opening and closing plate. One end of the pulling rod is fixed to the outer wall of the winding wheel, and the other end of the pulling rod is rotatably connected to the connecting rod three. The crushing device has a slot on the side near the locking key, and the locking key contacts the inner wall of the slot. The winding wheel has an arc groove on the side near the push rod, and the push rod contacts the inner wall of the arc groove.

[0012] The control device also includes a push rod that slides on the inner wall of the crushing device, a pull rod that rotatably connects the opening and closing plate to the push rod, and a striking block that slides and is embedded in the inner wall of the crushing device. The side of the push rod and the striking block that are close to each other is set as an arc surface. The mechanical locking of the key and the slot ensures that the opening and closing plate is firmly locked during the crushing operation, preventing accidental opening, ensuring operational safety, and maintaining the airtightness of the crushing chamber to improve efficiency. While the opening and closing plate rotates to discharge material, it drives the striking block to generate high-frequency mechanical vibration through the pull rod and the push rod.

[0013] The sliding plate is connected to the winding wheel by a steel wire. A torsion spring is provided between the winding wheel and the opening and closing plate. The torsion spring is provided to drive the winding wheel to reset. An elastic element is provided between the striking block and the crushing device. The elastic element is provided to drive the striking block to impact the crushing device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the magnetic block reciprocates under the drive of the sliding frame, which can scan a larger area and adsorb more fully than a fixed magnet. The inclined design of the push block automatically lifts and releases iron filings, realizing the self-cleaning of the magnetic separation unit. This avoids the problem of magnetic force attenuation caused by the accumulation of iron filings or the need for manual shutdown for cleaning. Triggered by the sliding frame, the scraper presses down and pushes the debris in the collection frame to the opening side, so that the operator can easily remove all iron filings by simply pulling out part of the collection frame. This greatly simplifies the maintenance steps, avoids spillage and secondary pollution during the cleaning process, and improves operational safety and cleanliness.

[0015] 2. In this invention, the reciprocating motion of the sliding frame serves as the power source, synchronously driving the material collection push plate and the leveling plate to move. The movement of these two will quickly organize the scattered and unevenly thick fragments on the conveyor belt into a centrally located and uniformly thick material belt. This creates ideal working conditions for the subsequent magnetic blocks, enabling their magnetic field to cover all materials with maximum efficiency, greatly reducing the leakage of iron filings caused by excessively thick or biased material accumulation.

[0016] 3. In this invention, the mechanical locking of the key and slot ensures that the opening and closing plate is firmly locked during the crushing operation, preventing accidental opening, thus ensuring operational safety and maintaining the airtightness of the crushing chamber to improve efficiency. While the opening and closing plate rotates to discharge material, it drives the striking block to generate high-frequency mechanical vibration through the pull rod and push rod. This effectively shakes off residual material adhering to the inner wall, blades and opening and closing plate of the crushing device, avoiding debris residue. Attached Figure Description

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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 One embodiment of the present invention is: a waste recycling and reuse device for masterbatch production, which includes a transport device 1 and a working frame 2 disposed on the surface of the transport device 1. The working frame 2 includes a crushing device and a positioning frame. The positioning frame is fixed on the surface of the transport device 1. The crushing device is disposed on the top of the positioning frame. The crushing device is used to crush the collected waste. The rotating shaft 3 is connected to the rotating shaft of the transport device 1 by a belt. The waste recycling and reuse device for masterbatch production further includes: a collection device disposed on the inner wall of the positioning frame for separating iron filings in the waste; a leveling device disposed on the inner wall of the positioning frame for leveling the crushed waste; and a control device disposed at the bottom of the crushing device for controlling the discharge of the crushed waste. The collecting device includes a rotating shaft 3 rotatably embedded in the inner wall of the positioning frame, a rack 4 sliding on the outer wall of the working frame 2, a sliding frame 5 sliding on the inner wall of the positioning frame, a magnetic block 6 sliding on the inner wall of the sliding frame 5, a fixing block 7 fixed on the outer wall of the magnetic block 6, an outer frame 8 fixed on the inner wall of the positioning frame, a collecting frame 9 sliding on the inner wall of the outer frame 8, and a push block 10 fixed on the surface of the outer frame 8. Half of the circumferential surface of the rotating shaft 3 is provided with teeth. The rack 4 includes upper teeth and lower teeth. The rack 4 matches the teeth on the surface of the rotating shaft 3. The sliding frame 5 is fixedly connected to the rack 4. A groove is opened on the outer wall of the positioning frame, and the collecting frame 9 contacts the inner wall of the groove.

[0021] The collecting device further includes a sliding plate 13 that slides on the surface of the outer frame 8, a connecting rod 12 rotatably connected to the sliding plate 13, a push plate 11 rotatably connected to the connecting rod 12, a scraper 14 disposed at the bottom of the sliding plate 13, a fixing rod 15 fixed to the surface of the outer frame 8, a sliding rod 16 fixed to the outer wall of the scraper 14, a rotating block 17 rotating on the outer wall of the sliding rod 16, and a blocking block 18 fixed to the outer wall of the sliding rod 16. One end of the connecting rod 12 is rotatably connected to the sliding plate 13, and the other end of the push plate 11 is rotatably connected to the connecting rod 12. A sliding groove is provided on the outer wall of the sliding plate 13, and the sliding rod 16 contacts the inner wall of the sliding groove. The scraper 14 moves and is slidably connected to the sliding plate 13, and the other end of the scraper 14 is slidably connected to the outer frame 8.

[0022] The push block 10 has an inclined surface on the side near the fixed block 7. The inclined surface of the push block 10 is to facilitate pressing the fixed block 7 to move downward. An elastic element is provided between the slide plate 13 and the outer frame 8. The elastic element is provided to drive the slide plate 13 to reset. A torsion spring is provided between the rotating block 17 and the slide rod 16. The torsion spring is provided to drive the rotating block 17 to reset. The fixed rod 15 has an inclined surface on the side near the rotating block 17. An elastic element is provided between the slide rod 16 and the slide plate 13. The elastic element is provided to drive the slide rod 16 to reset.

[0023] In this embodiment, when it is necessary to recycle the waste from the production of masterbatch, the collected waste needs to be poured into the working frame 2 for pretreatment. After the waste is poured into the working frame 2, the crushing device inside the working frame 2 will crush the waste. The crushed waste will fall onto the surface of the conveying device 1. When the conveying device 1 transports the waste, the magnetic block 6 will suck out the iron filings in the waste. Then, the processed waste is transported to the next stage for preheating treatment. When the conveying device 1 transports the crushed waste, the rotation of the shaft of the conveying device 1 will drive the rotation of the rotating shaft 3. The rotation of the rotating shaft 3 will drive the teeth to move, and the movement of the teeth will drive the rack 4 to move. When the teeth move, they will first contact the upper teeth and push the rack 4 to move away from the crushing device. When the rotating shaft 3 drives the teeth to rotate... After a half-turn, the toothed part will contact the lower tooth, causing the rotating shaft 3 to drive the rack 4 to reset. When the rack 4 moves away from the crushing device, it will drive the sliding frame 5 to move. The movement of the sliding frame 5 will drive the magnetic block 6 to move. The magnetic block 6 will attract iron filings in the waste below, and the attracted iron filings will be at the bottom of the sliding frame 5. When the magnetic block 6 moves, it will drive the fixed block 7 to move. When the magnetic block 6 moves above the outer frame 8, the fixed block 7 will contact the inclined surface of the push block 10, and the push block 10 will push the fixed block 7 to move upward. The upward movement of the fixed block 7 will drive the magnetic block 6 to move upward. When the magnetic block 6 moves upward, the elastic attraction of the magnetic block 6 to the bottom of the sliding frame 5 will weaken, and the iron filings at the bottom of the sliding frame 5 will fall into the collection frame 9. When the sliding frame 5 moves away from the crushing device, it will drive the rack 4 to reset. When the outer frame 8 moves in the direction of movement, it will contact the push plate 11. The sliding frame 5 will then push the push plate 11 to move. The movement of the push plate 11 will push the connecting rod 12 to move. The movement of the connecting rod 12 will push the slide plate 13 to move. The movement of the slide plate 13 will cause the scraper 14 to move towards the chute. The movement of the scraper 14 will cause the sliding rod 16 to move. The movement of the sliding rod 16 will cause the rotating block 17 to move. The movement of the rotating block 17 will contact the inclined surface of the fixed rod 15. The fixed rod 15 will then push the rotating block 17 to rotate. When the rotating block 17 rotates, it will be blocked by the stop block 18, preventing the rotating block 17 from rotating. The fixed rod 15 will then press the rotating block 17 downward. The downward movement of the rotating block 17 will push the scraper 14 downward. The downward movement of the scraper 14 will contact the debris on the inner wall of the collection frame 9. When triggered by the sliding frame 5, the scraper 14 pushes the debris towards the chute, allowing for easy cleaning of the debris inside the collection frame 9 by simply pulling out a portion of the frame. The magnetic block 6 reciprocates under the influence of the sliding frame 5, scanning a larger area and adsorbing more effectively than a fixed magnet. The inclined design of the pusher 10 automatically lifts and releases the iron filings, achieving self-cleaning of the magnetic separation unit and avoiding magnetic attenuation or the need for manual shutdown for cleaning due to iron filings accumulation. Triggered by the sliding frame 5, the scraper 14 presses down and pushes the debris inside the collection frame 9 towards the opening, allowing operators to easily remove all iron filings by simply pulling out a portion of the collection frame 9. This greatly simplifies maintenance and prevents spillage and secondary pollution during cleaning.This improved operational safety and cleanliness.

[0024] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, a waste recycling and reuse device for masterbatch production further includes a leveling device and a control device.

[0025] The leveling device includes a connecting rod 21 fixed to the bottom of the sliding frame 5, a push plate 23 disposed on the inner wall of the positioning frame, a connecting rod 22 rotatably connecting the push plate 23 and the connecting rod 21, a sliding plate 25 sliding on the inner wall of the positioning frame, and a connecting plate 24 rotatably connecting the push plate 23 and the sliding plate 25. The push plate 23 is fixedly connected to the positioning frame, and the part of the push plate 23 connected to the positioning frame is configured as a telescopic rod.

[0026] The leveling device further includes an outer rod 27 that slides on the surface of the push plate 23, an inner rod 28 that slides on the inner wall of the outer rod 27, a connecting rod 26 that rotatably connects the push plate 23 and the inner rod 28, a smoothing plate 29 that slides on the inner wall of the inner rod 28, and a push plate 291 that is disposed on the outer wall of the smoothing plate 29. One end of the connecting rod 26 is rotatably connected to the inner rod 28, and the other end of the connecting rod 26 is rotatably connected to the push plate 23.

[0027] An elastic element is provided between the push plate 23 and the positioning frame. The elastic element is provided to drive the push plate 23 to reset. An elastic element is provided between the flat plate 29 and the inner rod 28. The elastic element is provided to drive the flat plate 29 to reset. The side of the push plate 291 closest to the outer rod 27 is set as an inclined surface.

[0028] The control device includes a rotating opening and closing plate 31 at the bottom of the crushing device, a winding wheel 32 disposed on the outer wall of the opening and closing plate 31, a connecting rod 34 sliding on the bottom of the opening and closing plate 31, a pulling rod 33 connecting the connecting rod 34 and the winding wheel 32, a sliding rod 35 sliding on the inner wall of the opening and closing plate 31, a locking key 37 sliding on the inner wall of the opening and closing plate 31, a connecting rod 36 rotatably connecting the sliding rod 35 and the locking key 37, and a push rod 38 fixed on the outer wall of the opening and closing plate 31. One end of the pulling rod 33 is fixed to the outer wall of the winding wheel 32, and the other end of the pulling rod 33 is rotatably connected to the connecting rod 34. The crushing device has a slot on the side near the locking key 37, and the locking key 37 contacts the inner wall of the slot. The winding wheel 32 has an arc groove on the side near the push rod 38, and the push rod 38 contacts the inner wall of the arc groove.

[0029] The control device also includes a push rod 391 that slides on the inner wall of the crushing device, a pull rod 39 that rotatably connects the opening and closing plate 31 and the push rod 391, and a striking block 392 that is slidably embedded in the inner wall of the crushing device. The side of the push rod 391 and the striking block 392 that are close to each other is set as an arc surface.

[0030] The sliding plate 25 is connected to the winding wheel 32 by a steel wire. A torsion spring is provided between the winding wheel 32 and the opening and closing plate 31. The torsion spring is provided to drive the winding wheel 32 to reset. An elastic element is provided between the striking block 392 and the crushing device. The elastic element is provided to drive the striking block 392 to impact the crushing device.

[0031] In this embodiment, when the rack 4 drives the sliding frame 5 to slide back and forth on the inner wall of the positioning frame, it will drive the connecting rod 21 to move. The movement of the connecting rod 21 will push the connecting rod 22 to move. The movement of the connecting rod 22 will push the push plate 23 to move towards the center. The push plate 23 can push the waste on the surface of the transport device 1 to the center to avoid it being too scattered. The movement of the push plate 23 will pull the connecting plate 24 to move. The movement of the connecting plate 24 will pull the sliding plate 25 to slide. Through the connecting plate 24 and the sliding plate 25, the debris will not be transported to the back of the push plate 23 when it moves. When the push plate 23 moves, it will push the outer rod 27 to move. The movement of the outer rod 27 will contact the inclined surface of the push plate 291. The outer rod 27 will push the push plate 291 to move downward. The downward movement of the push plate 291 will drive the smoothing plate. As the push plate 291 moves downward, it will contact the debris on the surface of the conveying device 1. The movement of the push plate 23 will push the connecting rod 26 to move. The movement of the connecting rod 26 will push the inner rod 28 to move in the opposite direction of conveying debris. The smoothing plate 29 will then flatten the debris in the center, so that the magnetic block 6 can more completely attract the iron filings. The reciprocating motion of the sliding frame 5 serves as the power source, which synchronously drives the material collection push plate 23 and the smoothing plate 29 to move. The movement of these two will quickly organize the scattered and unevenly thick debris on the conveyor belt into a material belt with a central position and uniform thickness. This creates ideal working conditions for the subsequent magnetic block 6, so that its magnetic field can cover all the material with the highest efficiency, greatly reducing the iron filings that are missed due to excessive accumulation of material or bias to one side.

[0032] When the sliding plate 25 moves, it pulls the steel wire, which in turn pulls the winding wheel 32 to rotate. The rotation of the winding wheel 32 drives the pulling rod 33 to move, which in turn drives the connecting rod 34 to move. The connecting rod 34 then drives the sliding rod 35 to move, which in turn drives the connecting rod 36 to move. The connecting rod 36 then pulls the locking key 37 out of the slot, allowing the opening and closing plate 31 to rotate. The rotation of the winding wheel 32 drives the arc groove to move. When the limit of the opening and closing plate 31 is released, the movement of the arc groove drives the push rod 38 to move, which in turn drives the opening and closing plate 31 to rotate. The rotation of the opening and closing plate 31 discharges the debris from the crushing device. When plate 31 rotates, it pulls rod 39 to move. The movement of rod 39 drives push rod 391 to move. Push rod 391 contacts the arc surface of striking block 392, which pushes striking block 392 away from the inner wall of the crushing device. When push rod 391 disengages from striking block 392, striking block 392 is pulled back by elastic element. Striking block 392 then vibrates against the inner wall of the crushing device, making the debris discharge more comprehensive. The mechanical locking of key 37 and slot ensures that the opening and closing plate 31 is firmly locked during crushing operation, preventing accidental opening, ensuring operational safety, and maintaining the airtightness of the crushing chamber to improve efficiency.
