Description

Technical Field

[0001] The present invention relates to the technical field of plastic crushing, in particular to a crusher for recycling waste plastic bags. Background Art

[0002] Plastic bags are a widely used packaging material, primarily made of synthetic resins like polyethylene, rather than nitrocellulose. They play an indispensable role in people's daily lives, but improper disposal of used plastic bags can pose serious environmental risks. Discarded plastic bags are often carelessly discarded on city streets, tourist areas, water bodies, and along roads and railways. Due to their extremely long degradation cycle (often taking hundreds of years), these bags cause lasting ecological pollution. Therefore, the effective recycling and treatment of used plastic bags has important environmental and social benefits.

[0003] Crushing is a key step in the recycling process for plastic bags. Crushing significantly reduces the volume of plastic bags, saving storage space and reducing transportation costs. For recycling companies, this means more efficient material management and transportation, improving overall operational efficiency. Furthermore, the shredded plastic fragments are easier to process and reuse, helping to maximize resource utilization.

[0004] Although crushing is an important step in plastic bag recycling, existing waste plastic bag recycling equipment usually uses a simple crushing device to directly crush the plastic bags. During the crushing process, a large amount of dust attached to the surface of the plastic bags will be raised, which not only affects the air quality of the working environment, but may also cause dust accumulation inside the equipment, increase maintenance costs and failure rates. In addition, due to the lack of effective pretreatment steps, the plastic bags entering the crusher may carry a large amount of dust and impurities, which will affect the uniformity of the crushing and result in inconsistent sizes of the crushed plastic fragments, which in turn affects the quality of subsequent processing or reuse. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings, the technical problem of the present invention is to provide a crusher for recycling waste plastic bags.

[0006] The technical implementation scheme of the present invention is: a crusher for recycling waste plastic bags, including an outer frame, a sliding frame, a motor, a crushing roller, a connecting gear, a guide plate, a dust discharge plate, a flapping frame, a shaking assembly and a transmission assembly.

[0009] Optionally, it also includes a screening plate, a top frame, a top rod, a reset spring and a conveyor. The outer frame is located below the crushing roller and is slidably connected to an inclined screening plate, which is higher on the left and lower on the right. The left side of the bottom of the lifting rod is connected to a vertical top frame, and the left end face of the top frame is provided with multiple semicircular protrusions at intervals. The left end of the screening plate is connected to a top rod, which contacts and cooperates with the semicircular protrusions of the top frame. The top rod is slidably connected to the outer frame, and reset springs are connected between the front and rear ends and the wall of the outer frame for reset. A conveyor is installed at the bottom of the outer frame below the screening plate.

[0010] Optionally, it also includes a transmission gear, a protective frame, a transmission chain, a gear ring, a fixed block, a bucket, a volute spring and a blanking plate. The protective frame is connected to the right side of the outer frame. The upper and lower sides of the right side of the outer frame are connected to four transmission gears through rotating shafts, and are distributed in a rectangular shape. The rotating shaft passes through the protective frame. A transmission chain is wound around the transmission gears on the same side, and the two rotating shafts in the second row from the bottom to the top are connected to gear rings, and the gear rings are meshed with an adjacent connecting gear. A plurality of fixed blocks are connected to the transmission chain at intervals, and a bucket is rotatably connected between each front and rear symmetrical fixed block. A volute spring is connected between the front and rear end of the bucket and the fixed block. The bucket is located inside the protective frame, and a blanking plate is connected to the lower inner side of the outer frame at a position below the right end of the screening plate.

[0011] Optionally, it also includes a slide rail, a slider, a protruding rod, a push rod and an inclined plate. The right side of the outer frame is symmetrically connected to the slide rail, the front and rear sides of the dump bucket are connected to the slider, the slider slides in cooperation with the slide rail, the front and rear end faces of the dump bucket are connected to the protruding rod, the top right side of the outer frame is symmetrically connected to the push rod, the protruding rod is in contact with the push rod, the top right side of the outer frame is rotatably connected to the inclined plate, the opening surface of the dump bucket is arc-shaped, and its upward movement can push the inclined plate to rotate.

[0012] Optionally, it also includes a collecting bucket, an electric push rod, a guide rod and a push plate. The collecting bucket is connected to the position on the left side of the outer frame aligned with the dust exhaust plate. The electric push rod is installed on the left side of the collecting bucket. The middle of the collecting bucket is connected to the guide rod. The push plate is slidably connected to the guide rod. The push plate is slidably connected to the inside of the collecting bucket, and the push plate is connected to the telescopic rod of the electric push rod.

[0013] Optionally, an extraction pump and an air pipe are also included. The extraction pump is installed on the left side of the convex strip plate, and the air pipe is connected to the left side of the upper part of the sliding frame. Multiple air inlets are spaced apart on the air pipe. The air inlets pass through the interior of the sliding frame, and the air pipe and the extraction pump are connected by a hose.

[0014] Beneficial effects: 1. The beating rack set in the sliding frame can effectively beat the dust on the surface of the plastic bag and generate left and right shaking when the sliding frame moves up and down, which not only helps to drop the dust onto the dust discharge plate through the dust discharge hole, but also ensures the cleanliness of the plastic bag before entering the crushing process, avoiding the impact of excessive dust on the uniformity and efficiency of crushing. In addition, this design improves the quality of the subsequent crushing process and reduces the risk of equipment wear and failure due to dust accumulation.

[0015] 2. The crushed plastic fragments are efficiently screened by the shaking of the screening plate, which can accurately distinguish between fully crushed and incompletely crushed plastic fragments. Qualified plastic fragments are output through the conveyor and ready to enter the next process, while incompletely crushed plastic fragments slide to the right along the inclined surface of the screening plate to prepare for further processing. This classification mechanism ensures that each plastic fragment can be properly processed, improving the overall recycling efficiency and product quality.

[0016] 3. Through the coordinated work of the transmission chain and the tipping bucket, the equipment can realize the continuous transportation of insufficiently crushed plastics. The tipping bucket collects the insufficiently crushed plastic fragments from the drop plate and transports them to the sliding frame for secondary crushing. This can greatly improve the processing efficiency, reduce the need for manual intervention, and realize fully automated material circulation processing, ensuring the continuity and stability of the production process.

[0017] 4. The dust falling on the dust discharge plate is collected through the collection bucket, and a push plate is set to push the dust in the collection bucket out, which is convenient for operators to centrally process and clean up. It provides great convenience for operators, reduces the workload of dust cleaning, and improves work efficiency.

[0018] 5. The setting of the extraction pump can effectively extract the dust generated in the sliding frame into the external bag for collection, which not only reduces the dust around the device, improves the working environment, but also improves the cleanliness of the working area.

DETAILED DESCRIPTION

[0033] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0034] Example 1: A crusher for recycling waste plastic bags, such as Figures 1-6As shown, it includes an outer frame 1, a sliding frame 101, a motor 102, a crushing roller 103, a connecting gear 104, a guide plate 105, a dust exhaust plate 106, a beating frame 209, a shaking assembly and a transmission assembly. The sliding frame 101 is installed on the upper inner side of the outer frame 1. The bottom of the sliding frame 101 is in a state of high left and low right, and a plurality of dust exhaust holes are evenly opened. An oblique dust exhaust plate 106 is connected to the right side of the bottom of the sliding frame 101, which is in a state of low left and high right. The dust discharged from the dust exhaust hole will fall on the dust exhaust plate 106 and slide out along its inclined surface. There is a gap between the right side of the sliding frame 101 and the outer frame 1, which serves as a channel for plastic to pass through. An oblique guide plate 105 is connected in the gap. The guide plate 105 is located at a lower right position on the bottom of the sliding frame 101. A motor 102 is installed on the lower front side of the frame 1, and two crushing rollers 103 are connected to the left and right parallel rotation side of the inner lower side of the outer frame 1. The crushing rollers 103 are engaged with each other, and the front and rear ends of the crushing rollers 103 pass through the outer frame 1 and are connected with connecting gears 104. The two adjacent connecting gears 104 are engaged with each other. The output shaft of the motor 102 is connected to the crushing roller 103 on the right side, and a plurality of beating frames 209 are connected to the inner lower side of the sliding frame 101 at equal intervals along its inclined direction. The beating frames 209 can be rotated to beat the plastic in the sliding frame 101, so that the dust on its surface can be shaken out more quickly. A shaking component is provided on the outer frame 1, and a transmission component is provided on the sliding frame 101. The sliding frame 101 can slide up and down and left and right in the outer frame 1, and is supported and driven by the transmission component.

[0035] like Figure 3 、 Figure 5 and Figure 6 As shown, the shaking assembly includes a support rod 201, a lifting rod 202, a buffer spring 203, a protrusion 2010 and a protruding strip plate 2011. The support rod 201 is symmetrically welded to the front and back of the left side of the outer frame 1. The support rod 201 is slidably connected to the lifting rod 202. The lower end of the lifting rod 202 is provided with a horizontal sliding groove. The eccentric part of the connecting gear 104 on the left is connected with a protrusion, which is slidably connected to the sliding groove. The connecting gear 104 rotates through the protrusion to push the lifting rod 202. The lowering rod 202 moves up and down, and the upper ends of the lifting rods 202 are connected to the sliding frame 101 in a horizontal sliding manner, and two buffer springs 203 are connected between the sliding frame 101. A protrusion 2010 is connected to the lower end of the left side of the sliding frame 101, and a convex plate 2011 is connected between the upper ends of the two support rods 201. The protrusion 2010 is in contact with the convex plate 2011, and the convex plate 2011 can push the protrusion 2010 and the sliding frame 101 to repeatedly shake left and right.

[0036] like Figure 4 、 Figure 5 and Figure 6As shown, the transmission assembly includes a limit rod 204, a spur rack 205, a one-way gear 206, a spur gear 207 and a connecting chain 208. The limit rod 204 is connected to the front and rear side walls of the left side of the sliding frame 101. The upper end of the support rod 201 is horizontally slidably connected to the spur rack 205, and the spur rack 205 is vertically slidably connected to the limit rod 204. The front and rear ends of the flapping frame 209 pass through the sliding frame 101. The front and rear ends of the flapping frame 209 on the far left are connected to the one-way gear 206, which meshes with the spur rack 205. The front and rear ends of the remaining flapping frames 209 are welded with spur gears 207. A connecting chain 208 is wound around the spur gear 207 and the one-way gear 206 on the same side to ensure that all flapping frames 209 rotate synchronously.

[0037] When recycling and crushing plastic bags, the operator first puts the waste plastic bags into the sliding frame 101, then starts the motor 102. The output shaft of the motor 102 rotates to drive the crushing roller 103 and the connecting gear 104 to rotate. The connecting gear 104 on the left side drives the lifting rod 202 to move up and down through the protrusion. The movement of the lifting rod 202 drives the sliding frame 101 and the protrusion 2010 on it to move up and down and contact with the protruding strip plate 2011. This interaction causes the sliding frame 101 to vibrate left and right, and the buffer spring 203 is used in this process. The necessary reset force is provided to ensure that the sliding frame 101 can stably perform periodic motion. When the sliding frame 101 moves left and right, the limit rod 204 drives the spur rack 205 to move left and right. The spur rack 205 is restricted by the support rod 201 and can only move in the horizontal direction and cannot slide up and down. As the sliding frame 101 moves up and down, the one-way gear 206, the spur gear 207, the connecting chain 208 and the beating frame 209 move up and down synchronously. The one-way gear 206 meshes with the spur rack 205, forcing the one-way gear 206 to rotate in a fixed direction. , thereby driving the spur gear 207 to rotate through the connecting chain 208, and finally driving the slapping frame 209 to rotate continuously in the same direction. The rotating action of the slapping frame 209 effectively slaps the plastic bags in the sliding frame 101, shaking off the dust attached to the surface. The dust will fall onto the dust discharge plate 106 below through the dust discharge holes, achieving preliminary cleaning of the plastic bags and ensuring the quality of subsequent crushing. When the sliding frame 101 moves downward, due to the design characteristics of the one-way gear 206, it will not rotate downward, so it will only rotate when the sliding frame 101 moves upward. This ensures that the beating frame 209 always rotates in the same direction, avoiding the problem of plastic bag entanglement or blockage that may be caused by reverse rotation. Under the action of the beating frame 209, the plastic bags that have been preliminarily cleaned slide smoothly along the inclined surface of the sliding frame 101 to the guide plate 105, and are further guided between the two relatively rotating crushing rollers 103. The crushing rollers 103 apply shear force to the plastic bags, crushing them into smaller particles, which fall downward after crushing for subsequent collection. After the operation is completed, the motor 102 is turned off to collect the processed dust and crushed plastic.

[0038] Example 2: Based on Example 1, Figure 1 、 Figure 7 and Figure 8As shown, it also includes a screening plate 301, a top frame 302, a top rod 303, a return spring 304 and a conveyor 4. The outer frame 1 is located below the crushing roller 103 and is slidably connected to the oblique screening plate 301, which is in a state of left high and right low. The left side of the bottom of the lifting rod 202 is connected to a vertical top frame 302, and the left end surface of the top frame 302 is provided with a plurality of semicircular protrusions at intervals. The left end of the screening plate 301 is connected to a top rod 303, which contacts and cooperates with the semicircular protrusions of the top frame 302. The top rod 303 is slidably connected to the outer frame 1, and a return spring 304 is connected between the front and rear ends and the wall of the outer frame 1 for reset. The conveyor 4 is installed at the bottom of the outer frame 1 below the screening plate 301. After screening, the fully crushed plastic falls onto the conveyor 4 and is transported to the left by the conveyor 4 for subsequent collection or transfer to the next process.

[0039] The crushed plastic fragments fall directly onto the screening plate 301 from the bottom of the crushing roller 103, and the lifting frame 302 is driven to slide up and down when the lifting rod 202 slides up and down. The semicircular protrusion on the lifting frame 302 cooperates with the push rod 303. When the lifting frame 302 moves up and down, the semicircular protrusion repeatedly pushes the push rod 303 to move left and right. When the push rod 303 is pushed, the reset spring 304 is stretched. When the thrust disappears, the reset spring 304 is reset, and the push rod 303 returns to its initial position. This process gives the screening plate 301 a continuous left and right shaking. The screening plate 30 This shaking of 1 helps to evenly distribute the plastic fragments thereon and promotes them to pass through the holes on the screen plate 301. The fully crushed plastic fragments, due to their small size, can smoothly pass through the holes on the screen plate 301 and fall down along the holes to the conveyor 4 below. After the conveyor 4 is started, these qualified plastic fragments will be transported to the left for collection or transfer to the next processing step. As for the larger plastic fragments that are not fully crushed, since they cannot pass through the holes of the screen plate 301, they will slide to the right under the action of the inclined surface of the screen plate 301 for subsequent processing.

[0040] like Figure 1 and Figures 8-12As shown, it also includes a transmission gear 501, a protective frame 5011, a transmission chain 502, a gear ring 503, a fixed block 504, a dump bucket 505, a spiral spring 506 and a blanking plate 507. The right side of the outer frame 1 is connected to the protective frame 5011. The upper and lower sides of the right side of the outer frame 1 are connected to four transmission gears 501 through rotating shafts, and are distributed in a rectangular shape. The rotating shaft passes through the protective frame 5011. The transmission chain 502 is wound around the transmission gears 501 on the same surface. The two rotating shafts in the second row from the bottom to the top are both welded with a gear ring 503. The gear ring 503 is meshed with an adjacent connecting gear 104. In order to transmit power to the transmission gear 501 and the transmission chain 502, a plurality of fixed blocks 504 are connected to the transmission chain 502 at intervals, and a tipping bucket 505 is rotatably connected between each front and rear symmetrical fixed block 504. A spiral spring 506 is connected between the front and rear ends of the tipping bucket 505 and the fixed block 504. The tipping bucket 505 is located inside the protective frame 5011, and an inclined blanking plate 507 is connected to the lower inner side of the outer frame 1 at a position slightly below the right end of the screening plate 301, which is in a state of high on the left and low on the right, so that the material on the screening plate 301 can fall onto the blanking plate 507 and fall into the tipping bucket 505 through the blanking plate 507.

[0041] like Figure 10-12 As shown, it also includes a slide rail 601, a slider 602, a protruding rod 603, a stop rod 604 and an inclined plate 605. The slide rail 601 is symmetrically welded to the front and rear of the right side of the outer frame 1. The front and rear sides of the tipping bucket 505 are connected with sliders 602. The slider 602 slides with the slide rail 601. When the tipping bucket 505 moves to the right side of the outer frame 1, the slider 602 slides along the slide rail 601 to limit the angle of the tipping bucket 505 so that it remains parallel. The front and rear ends of the tipping bucket 505 are connected with protruding rods 603. , a push rod 604 is welded symmetrically on the front and back of the top right side of the outer frame 1, and the protruding rod 603 contacts and cooperates with the push rod 604. The push rod 604 presses against the protruding rod 603, which can make the bucket 505 rotate and open toward the outer frame 1, so that the plastic fragments in the bucket 505 fall into the outer frame 1. The top right side of the outer frame 1 is rotatably connected with an inclined plate 605, which is lower on the left and higher on the right. The opening surface of the bucket 505 is arc-shaped, and its upward movement can push the inclined plate 605 to rotate, so that the bucket 505 can pass over the inclined plate 605.

[0042] The larger plastic fragments that fail to pass through the holes of the screening plate 301 slide to the right along its inclined surface and eventually fall onto the blanking plate 507 below. The plastic fragments on the blanking plate 507 then slide into the tipping bucket 505, ready for secondary transportation. The connecting gear 104 rotates under the drive of the motor 102, transmitting power to the ring gear 503, and the ring gear 503 drives the rotating shaft, the transmission gear 501 and the transmission chain 502 to rotate synchronously, wherein the transmission chain 502 rotates clockwise. The movement of the transmission chain 502 transports the tipping bucket 505 vertically from bottom to top, ensuring that each tipping bucket 505 can accurately collect the plastic fragments that fall from the blanking plate 507. The setting of the slide rail 601 makes it possible for the slider 602 on the bucket 505 to cooperate with the slide rail 601 when the bucket 505 is transported from the right to the left, and then move upward along the slide rail 601, which can ensure that the bucket 505 filled with plastic fragments remains horizontal and moves upward to avoid the plastic fragments falling or getting stuck due to shaking. When the bucket 505 rises to the top and contacts the inclined plate 605, the curved surface of the bucket 505 will push the inclined plate 605 to rotate upward, so that the inclined plate 605 is temporarily lifted. Once the bucket 505 passes over the inclined plate 605, the inclined plate 605 automatically resets under the action of gravity and returns to the initial position, preparing for the passage of the next bucket 505. Be prepared. When passing the bend, the slider 602 on the tipping bucket 505 separates from the slide rail 601, and the protruding rod 603 contacts the push rod 604. At this time, the push rod 604 prevents the tipping bucket 505 from continuing to move, forcing the tipping bucket 505 to rotate. The spiral spring 506 is deformed in this process. When the tipping bucket 505 rotates, the opening faces the outer frame 1, and the plastic fragments inside fall smoothly into the outer frame 1 and are then guided to the sliding frame 101 to prepare for secondary crushing. The design of the inclined plate 605 not only provides an effective diversion path for the plastic fragments, but also ensures that they can smoothly enter the outer frame 1. When the tipping bucket 505 continues to move with the conveyor After the moving chain 502 moves and the protruding rod 603 disengages from the supporting rod 604, the scroll spring 506 quickly rebounds, driving the tipping bucket 505 to reverse and reset, restoring it to its original state and preparing to receive the next batch of plastic fragments. The transmission chain 502 continuously drives the multiple tipping buckets 505 to perform a circular motion, achieving continuous conveying and secondary processing of insufficiently crushed plastic. The bottom surface of the protective frame 5011 is curved. If some plastic fragments fall to the bottom of the protective frame 5011, the tipping bucket 505, conveyed by the chain, will be able to pick up the plastic fragments at the bottom when it turns from left to right at the bottom, ensuring that the plastic fragments are fully collected in the tipping bucket 505. After the entire crushing operation is completed, the motor 102 is turned off.

[0043] like Figure 13As shown, it also includes a collecting bucket 701, an electric push rod 702, a guide rod 703 and a push plate 704. The collecting bucket 701 is welded at a position aligned with the dust discharge plate 106 on the left side of the outer frame 1. The dust falling from the dust discharge plate 106 will slide into the collecting bucket 701. The electric push rod 702 is installed on the left side of the collecting bucket 701 by bolts.
