Description

Technical Field

[0001] This invention relates to the field of wood-plastic composite board waste recycling technology, and in particular to a waste recycling device and recycling method based on wood-plastic composite board production. Background Technology

[0002] Wood-plastic composites, as an environmentally friendly building material, generate a large amount of scrap and substandard products during their production. Recycling and reusing these wastes not only aligns with the principles of green manufacturing but also has significant economic value. Currently, the mainstream recycling method involves using crushing equipment to pulverize these wastes into fine particles, which can then be reused as raw materials in the production line.

[0003] Referring to patent application CN110696226A, a wood-plastic composite material crushing and recycling device includes a crushing and recycling box, a crushing and recycling drive device on the crushing and recycling box, a controller outside the crushing and recycling box, an automatic feeding device on the crushing and recycling box, a saw blade crushing device inside the crushing and recycling box, and a material crushing and recycling device above the crushing and recycling box. The high-speed rotation of the crushing saw blade, driven by the crushing shaft, pulverizes the wood-plastic composite material, effectively saving the steps of crushing the wood-plastic composite material. The crushing by the saw blade ensures more thorough pulverization. The rotation of the reciprocating screw causes the push frame to move reciprocally, enabling the device to automatically push the wood-plastic composite material for crushing. The wood-plastic composite material is fixed by a supporting base plate, a supporting top plate, and an extrusion baffle, ensuring the stability of the wood-plastic composite material during crushing.

[0004] The following problems exist during use: the extremely tough long wood fibers in the waste are very easy to get tangled in the crusher shaft and blades, causing frequent jamming and shutdown, which seriously restricts continuous production; the loose and uneven waste is easy to clog the feed inlet, and the sudden input of large pieces of material will cause a huge impact, leading to the risk of "choking", threatening the safety and life of the equipment; due to the lack of effective pretreatment, the crusher needs to directly process complete fibers and loose materials, resulting in high energy consumption, low efficiency, and difficulty in ensuring uniform output particle size.

[0005] Therefore, it is necessary to provide a waste recycling device and recycling method based on wood-plastic composite board production to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a waste recycling device and method based on wood-plastic composite board production, so as to solve the problems of the prior art mentioned in the background.

[0015] As a further aspect of the present invention: the feeding assembly includes two turntables, which are rotatably connected to the two sides inside the feeding trough, and a connecting shaft is fixedly connected to the opposite side of each turntable. A striking plate is provided between the two turntables, and the connecting shafts are fixedly connected to both ends of the striking plate. The connecting shafts extend into the reciprocating frame and are slidably connected to the reciprocating frame. A fixed frame is fixedly connected to the top of the feeding trough, and the striking plate passes through the fixed frame and is slidably connected to the fixed frame.

[0016] As a further embodiment of the present invention: the transmission component includes two rotating disks, which are respectively fixedly connected to both ends of the connecting cylinder, and an arc-shaped rack corresponding to a plurality of processing frames is fixedly connected to the outer side of the rotating disks. A rotating shaft is rotatably connected to both sides of the fixed cylinder, and a second gear is fixedly connected to the outer side of the rotating shaft. A transmission shaft is fixedly connected to the outer side of the rotating disk, and the transmission shaft is rotatably connected to the feed chute.

[0017] As a further embodiment of the present invention: two cleaning plates are provided at the bottom of the fixed plate, and side plates are provided at both ends of the two cleaning plates.

[0019] A method for recycling waste materials produced from wood-plastic composite boards includes the following steps:

[0020] Step 1: When waste material is fed into the feed chute, and the connecting cylinder drives multiple processing frames to rotate, the waste material on the feed chute falls into the processing frames in sequence.

[0021] Step 2: When the processing frame rotates to the bottom of the feeding trough, the transmission component will drive the unloading assembly to push the waste material inside the feeding trough into the processing frame;

[0022] Step 3: After the waste material enters the processing box, it is cut by the cutting components inside the processing box.

[0023] Step 4: As the connecting cylinder rotates, the cut waste material inside the processing frame falls into the crusher and is crushed by the crushing components.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. As the connecting cylinder rotates, the waste material cut inside the processing frame falls into the crusher and is crushed by the crushing components. When the material passes through the processing frame, it is cut through pre-treatment to remove long wood fibers. The feed consists of small, uniformly sized pieces, which avoids the impact load and "choking" phenomenon caused by feeding large, loose waste into the main crusher, thus making the crushing process more efficient.

[0026] 2. Drive the two moving frames to move closer to each other. This action, on the one hand, causes the baffle to gather and initially compress the loose waste material, and on the other hand, causes the rotating cutting blades to move relative to each other in the waste material, achieving a highly efficient "extrusion-shearing" composite cutting effect. In addition, as the connecting cylinder continues to rotate, the entire processing frame tumbles, causing the waste material inside to constantly change position, ensuring that there are no dead angles in the cutting and that the processing is more thorough.

[0027] 3. Through the reciprocating motion of the moving frame during the cutting process, the cleaning plate is driven to continuously perform the "pull-down" cycle, thereby forming a continuous and powerful impact cleaning of the bottom of the filter plate, effectively shaking off and scraping off the powder and debris clogging the filter holes, ensuring the long-term permeability of the filter plate.

[0028] 4. To ensure smooth flow of waste material at the interface between the feed chute and the processing frame, this solution incorporates an automatic unblocking mechanism precisely linked to the rotational motion. The key feature is that this mechanism is only triggered and performs the unblocking action when the processing frame rotates directly below the feed chute. Attached Figure Description

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0043] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0044] like Figures 1 to 11 As shown, a waste recycling device and method based on wood-plastic composite board production includes the following embodiments:

[0045] The system includes a crusher 1, which contains a crushing assembly. The crushing assembly includes two crushing rollers 101, both rotatably connected inside the crusher 1. Two drive motors are fixedly connected to the outside of the crusher 1, and the output shafts of the drive motors are fixedly connected to the crushing rollers 101. The system also includes:

[0046] Fixed cylinder 2 is fixedly connected to the top of crusher 1 and communicates with crusher 1. A connecting cylinder 201 is rotatably connected inside the fixed cylinder 2. Multiple processing frames 4 are fixedly connected to the outside of the connecting cylinder 201. The multiple processing frames 4 are arranged in a ring around the fixed cylinder 2. A dividing component for cutting waste is provided inside the processing frame 4. An arc plate 400 is fixedly connected between the multiple processing frames 4.

[0047] The feeding trough 3 is fixedly connected to the top of the fixed cylinder 2 and communicates with the fixed cylinder 2. The feeding trough 3 is equipped with a feeding component. A transmission component is provided between the connecting cylinder 201 and the feeding component. When the processing frame 4 rotates to the bottom of the feeding trough 3, the feeding component is driven by the transmission component to push the feeding component to feed.

[0048] In practice, long wood fibers in wood-plastic waste are prone to getting tangled on the crusher's shaft and blades during the crushing process, causing blockages and requiring frequent shutdowns for cleaning, which affects continuous production. When waste is fed into the feed chute 3, and the connecting cylinder 201 drives multiple processing frames 4 to rotate, the waste on the feed chute 3 falls into the processing frames 4 in sequence. When the processing frames 4 rotate to below the feed chute 3, the transmission component drives the feeding assembly to push the waste inside the feed chute 3 into the processing frames 4. After the waste enters the processing frames 4, it is cut by the cutting assembly inside the processing frames 4. As the connecting cylinder 201 rotates, the cut waste inside the processing frames 4 falls into the crusher 1 and is crushed by the crushing assembly. When the material is cut inside the processing frames 4, the waste is pre-treated to remove the long wood fibers. The feed consists of small, uniformly sized pieces, avoiding the impact load and "choking" phenomenon caused by feeding large, loose waste into the main crusher, thus making the crushing process more efficient.

[0049] In this embodiment: a fixing plate 401 is fixedly connected inside each of the multiple processing frames 4, a filter plate 402 is fixedly connected inside the fixing plate 401, a connecting tube 202 is rotatably connected to one end of the connecting cylinder 201, the connecting tube 202 is connected to an external air pump, a first motor is fixedly connected to the outside of the fixing cylinder 2, the output shaft end of the first motor is fixedly connected to the connecting cylinder 201, and an internal gear ring 607 is fixedly connected to one side of the fixing cylinder 2.

[0050] In practical implementation, this solution connects the processing frame 4 to the connecting cylinder 201, and the outer side of the connecting cylinder 201 is rotatably connected to the connecting pipe 202. When the dust generated during processing inside the processing frame 4 passes through the filter plate 402, it enters the interior of the connecting cylinder 201 and is then discharged through the connecting pipe 202. This design achieves active capture and efficient removal of dust at the source of dust generation, which not only significantly reduces the amount of dust emitted in the subsequent main crushing process, but also effectively protects the cleanliness of the production environment and the health and safety of operators, demonstrating good environmental performance.

[0051] Example 2: The segmentation component includes a pusher and a cutter. The cutter includes two opposing movable frames 5, which are slidably mounted on the top of the fixed plate 401. Multiple rotating rods 501 are rotatably connected to the top of the movable frames 5. Cutting blades 502 are fixedly connected to the outer side of each of the multiple rotating rods 501. Transmission wheels 503 are fixedly connected to the outer side of each of the multiple rotating rods 501. The multiple transmission wheels 503 are driven by belts. A second motor is fixedly connected inside the movable frame 5. The output shaft of the second motor is fixedly connected to one of the transmission wheels 503.

[0052] The cutting component also includes two baffles 7, which are arranged opposite to each other. Multiple through slots are provided on the outer side of the baffles 7, and multiple cutting blades 502 partially pass through the multiple through slots. Multiple telescopic rods 704 are fixedly connected between the baffles 7 and the moving frame 5. Springs are sleeved on the outer side of each telescopic rod 704. A stop plate 701 is fixedly connected to the outer side of the baffles 7, and an elastic pad 702 is fixedly connected between the stop plate 701 and the top of the processing frame 4.

[0053] In practice, when waste material enters the processing frame 4 through the feeding chute 3 between two baffles 7, the second motor in the cutting component on one side of the baffle 7 drives one of the rotating rods 501 to rotate. Through the transmission wheel 503 and belt drive, multiple rotating rods 501 rotate, and multiple cutting blades 502 on the outside of the rotating rods 501 rotate. The cutting blades 502 pass through the baffle 7 to cut the waste material. When the baffle 7 is in normal condition, the telescopic rod 704 is in a retracted state by the spring traction, exposing the cutting blades 502 in the through slot, thereby cutting the waste material. At the same time, the pusher starts to work, driving the two moving frames 5 to move closer to each other. This action, on the one hand, causes the baffle 7 to gather and initially compress the loose waste material, and on the other hand, causes the rotating cutting blades 502 to move relative to each other in the waste material, achieving a highly efficient "compression-shear" composite cutting effect. In addition, as the connecting cylinder 201 continues to rotate, the entire processing frame 4 tumbles, causing the waste material inside to constantly change position, ensuring that there are no dead angles in the cutting and that the processing is more thorough.

[0054] After cutting, the pusher drives the moving frame 5 to move towards the side wall of the processing frame 4. At this time, the abutment 701 on the baffle 7 first contacts and is blocked by the inner wall of the processing frame 4. The moving frame 5 continues to move, forcing the spring on the telescopic rod 704 to be compressed, and the entire cutting assembly is displaced relative to the baffle 7, causing the cutting blade 502 to gradually retract into the through groove. During this process, the edge of the through groove of the baffle 7 acts like a scraper, scraping away the residual waste adhering to the cutting blade 502, completing the self-cleaning process.

[0055] Finally, when the connecting cylinder 201 rotates to the point where the opening of the processing frame 4 faces downward, the cut waste material loses its restraint and, under the action of gravity, falls smoothly from between the two cleaned baffles 7 into the crusher 1 below, entering the next crushing process.

[0056] In this embodiment, the pusher includes two transmission rods 601, which are respectively disposed on both sides of the processing frame 4. The transmission rods 601 are rotatably connected to the processing frame 4 through a support plate. A first gear 606 is fixedly connected to one end of the transmission rod 601. The first gear 606 meshes with an internal gear ring 607. Multiple worm gears 602 are fixedly connected to the outside of the transmission rod 601. A worm wheel 603 is meshed with the outside of each of the multiple worm gears 602. A reciprocating screw 604 is fixedly connected to the outside of the worm wheel 603. The reciprocating screw 604 is rotatably connected to the processing frame 4 through a support plate. A moving cylinder 605 is connected to the outside of the reciprocating screw 604 through a ball nut pair. The moving cylinder 605 passes through the processing frame 4 and is fixedly connected to the moving frame 5.

[0057] In specific implementation, when the processing frame 4 rotates with the connecting cylinder 201, the first gear 606 at one end of the transmission rod 601 on both sides of the processing frame 4 will mesh with the internal gear ring 607, thereby rotating the first gear 606. The first gear 606 drives the transmission rod 601 to rotate, and the transmission rod 601 drives the worm gear 602 fixedly connected to the outside to rotate. The worm gear 602 drives the worm wheel 603 to rotate through meshing. The worm wheel 603 drives the reciprocating screw 604 to rotate, thereby causing the moving cylinder 605 outside the reciprocating screw 604 to reciprocate. This causes the moving cylinder 605 to drive the moving frame 5 to move, causing the cutting parts to move relative to each other, thereby repeatedly cutting the waste between the two baffles 7.

[0058] Example 3: Two cleaning plates 801 are provided at the bottom of the fixed plate 401. Side plates 802 are provided at both ends of the two cleaning plates 801. The side plates 802 are fixedly connected to the inside of the processing frame 4. A sliding groove is opened on the outer side of the side plate 802. A limiting rod 803 is fixedly connected to the outer side of the cleaning plate 801. The limiting rod 803 extends into the sliding groove opened on the outer side of the side plate 802. A connecting plate 804 is fixedly connected to the bottom of the fixed plate 401. A sliding rod 805 is slidably connected to the outer side of the connecting plate 804. The sliding rod 805 passes through the cleaning plate 801 and is slidably connected to the cleaning plate 801. A traction rope 806 is fixedly connected between the cleaning plate 801 and the moving frame 5.

[0059] In practical implementation, when the waste powder from cutting enters the connecting cylinder 201 through the filter plate 402, the filter plate 402 will inevitably become clogged with each use, preventing a large amount of powder from passing through it. Therefore, in this design, when the processing frame 4 rotates with the connecting cylinder 201 to the unloading position with the opening facing downwards, the cleaning plate 801 below the fixed plate 401 naturally descends under gravity. Guided by the limiting rod 803 in the sliding groove of the side plate 802, the cleaning plate 801 is precisely guided to directly below the filter plate 402. At this time, the cleaning brush at the top of the cleaning plate 801 contacts the bottom of the filter plate 402. In this position, the side plate 802 and the filter plate 402 are in contact, so that the traction rope 806 between the cleaning plate 801 and the moving frame 5 is in a taut state. This design couples the cleaning action with the cutting drive system.

[0060] Upward stroke: When the pusher drives the two moving frames 5 to approach each other, the tensioned traction rope 806 will pull the cleaning plate 801, causing it to move upward against gravity, forming an upward scraping impact on the filter plate 402.

[0061] Falling stroke: When the two moving frames 5 move away from each other, the traction rope 806 slackens, and the cleaning plate 801 falls again under the action of gravity, generating a downward impact on the filter plate 402.

[0062] Through the reciprocating motion of the moving frame 5 during the cutting process, the cleaning plate 801 is driven to continuously perform the "pull-down" cycle, thereby forming a continuous and powerful impact cleaning on the bottom of the filter plate 402, effectively shaking off and scraping off the powder and debris clogging the filter holes, and ensuring the long-term permeability of the filter plate.

[0063] Example 4: The feeding assembly includes two turntables 1001, which are rotatably connected to the two sides inside the feeding trough 3, and a connecting shaft 1002 is fixedly connected to the opposite side of each turntable 1001. A striking plate 1004 is provided between the two turntables 1001, and the connecting shaft 1002 is fixedly connected to both ends of the striking plate 1004. The connecting shaft 1002 extends into the reciprocating frame 1003 and is slidably connected to the reciprocating frame 1003. A fixing frame 10 is fixedly connected to the top of the feeding trough 3, and the striking plate 1004 passes through the fixing frame 10 and is slidably connected to the fixing frame 10.

[0064] The transmission component includes two rotating disks 901, which are fixedly connected to both ends of the connecting cylinder 201. Arc-shaped racks 902, corresponding to multiple processing frames 4, are fixedly connected to the outer side of the rotating disks 901. Rotating shafts 904 are rotatably connected to both sides of the fixed cylinder 2. Second gears 903 are fixedly connected to the outer side of the rotating shafts 904. A transmission shaft 905 is fixedly connected to the outer side of the turntable 1001. The transmission shaft 905 is rotatably connected to the feed trough 3. A driven wheel 906 is fixedly connected to the outer side of the transmission shaft 905. A driving wheel 907 is fixedly connected to the outer side of the rotating shaft 904. The driven wheel 906 and the driving wheel 907 are connected by a belt drive.

[0065] In practical implementation, to ensure the smooth flow of waste material at the interface between the feed trough 3 and the processing frame 4, this solution incorporates an automatic unblocking mechanism precisely linked to the rotational motion. Its core principle is that this mechanism is only triggered and performs the unblocking action when the processing frame 4 rotates directly below the feed trough 3.

[0066] The specific transmission process is as follows:

[0067] When the connecting cylinder 201 drives the processing frame 4 to rotate to the receiving station, the rotating disk 901 fixed on it rotates accordingly. The arc-shaped rack 902 on the outer side of the disk meshes with the second gear 903, thereby driving the rotating shaft 904 to rotate. The power is then transmitted to the transmission shaft 905 via the belt drive of the driving wheel 907 and the driven wheel 906, and finally drives the turntable 1001 to rotate.

[0068] The rotational motion of the turntable 1001 is converted into the vertical reciprocating motion of the striking plate 1004 through the cooperation of the connecting shaft 1002 and the reciprocating frame 1003. The striking plate 1004 then periodically strikes the connection interface between the feed chute 3 and the processing frame 4, effectively dispersing any material bridging or blockage that may occur, ensuring the smooth input of waste materials.

[0069] Once the processing frame 4 has rotated past the station, the arc-shaped rack 902 disengages from the second gear 903, the entire transmission chain stops moving, and the striking plate 1004 immediately resets and comes to a stop. This design ensures the precision and energy efficiency of the unblocking operation, avoiding unnecessary idle operations.

[0070] A method for recycling waste materials produced from wood-plastic composite boards includes the following steps:

[0071] Step 1: When waste material is fed into the feed chute 3, and when the connecting cylinder 201 drives multiple processing frames 4 to rotate, the waste material on the feed chute 3 falls into the processing frame 4 in sequence.

[0072] Step 2: When the processing frame 4 rotates to the bottom of the feeding trough 3, the transmission component will drive the unloading assembly to push the waste material inside the feeding trough 3 into the processing frame 4;

[0073] Step 3: After the waste material enters the processing frame 4, it is cut by the cutting component inside the processing frame 4.

[0074] Step 4: As the connecting cylinder 201 rotates, the waste material cut inside the processing frame 4 falls into the crusher 1 and is crushed by the crushing components.
