Description

Technical Field

[0001] This invention relates to the field of wood-plastic waste treatment technology, specifically to a wood-plastic material recycling and treatment equipment. Background Technology

[0002] Wood-plastic composite (WPC) materials, an environmentally friendly composite material made of wood fibers and a plastic matrix, combine the processing properties of wood with the weather resistance of plastics, and are widely used in outdoor building materials, decorative materials, and other fields. With the increasing use of WPC materials, the need for recycling and processing the waste generated after disposal is becoming increasingly urgent. In the recycling and processing of WPC materials, crushing equipment is needed to crush waste WPC boards, scraps, and other waste materials to facilitate subsequent processing.

[0003] Currently, the crushing of wood-plastic composite (WPC) waste is mostly done by directly feeding the waste into crushing equipment. Existing crushing equipment typically uses a single-stage crushing roller for initial crushing, followed by a fine crushing roller to reduce the particle size. While this type of crushing equipment can crush WPC, it has the following drawbacks in practical use:

[0004] Waste wood-plastic composite products, especially outdoor wood-plastic boards, often have dirt adhering to their surfaces. If they are directly fed into crushing equipment after recycling, a large amount of dirt will be mixed into the crushed wood-plastic powder, greatly reducing the quality of the powder and causing a significant decline in the mechanical properties and surface quality of the recycled wood-plastic material. If the wood-plastic boards are transported to cleaning equipment for cleaning and then transferred to crushing equipment by personnel, although dirt can be removed, this greatly increases the workload of workers and reduces the efficiency of wood-plastic board recycling.

[0047] The waste crushing mechanism 4 includes a support frame 41, a crushing shell 42, a crushing roller 43, a guide component 44, a fixed shell 45, and a crushing component 46. The support frame 41 is arranged on the side of the support frame 31 away from the conveyor frame 11. The crushing shell 42 is fixedly installed on the top of the support frame 41 and below the highest point of the conveyor belt 36. The crushing roller 43 is symmetrically and rotatably installed inside the crushing shell 42. The guide component 44 is installed at the bottom of the crushing shell 42. The fixed shell 45 is fixedly installed at the bottom of the crushing shell 42 and sleeved outside the guide component 44. The crushing component 46 is installed inside the fixed shell 45 and below the guide component 44. The lower cleaning roller 33 can extend into the fixed shell 45 and contact the crushing component 46.

[0048] In use, it realizes continuous operation of wood-plastic waste from conveying, cleaning to crushing and pulverizing; when conveying wood-plastic waste, the waste conveying mechanism 1 can squeeze and crush the soil on the surface of the waste to remove the soil on the surface of the wood-plastic board. The lower cleaning roller 33 and the upper cleaning roller 34 of the roller brush cleaning mechanism 3 rotate in opposite directions, which can further clean the residual impurities on the surface of the waste and improve the cleanliness of the crushed wood-plastic board; the waste crushing mechanism 4 completes the resource utilization of waste through the initial crushing of the crushing roller 43 and the fine crushing of the crushing component 46, and the lower cleaning roller 33 can extend into the fixed shell 45 to contact the crushing component 46, thereby achieving the cleaning effect of the crushing component 46 and facilitating the regular cleaning of the crushing component 46.

[0049] Combination Figures 1-13As shown, the support component 32 includes a movable seat 321 horizontally slidably mounted on a support frame 31 along the direction of the conveyor frame 11. An electric slider connected to the movable seat 321 is fixedly mounted on the support frame 31. Vertical telescopic rods are symmetrically fixedly mounted on the top of the movable seat 321. A hinge frame 322 is fixedly mounted on the top of the two telescopic rods. A drive rod 325, fixedly connected to the hinge frame 322, is fixedly mounted on the movable seat 321.

Vertical telescopic rods are symmetrically fixed on the hinge block 323. A support base 324 is fixedly mounted on the top of the two telescopic rods. A drive rod 326, fixedly connected to the support base 324, is fixedly mounted on the hinge block 323. The lower cleaning roller 33 is rotatably mounted on the support. On the support 324, the driving component 37 includes a motor 371 fixedly mounted on the support 324.

The output shaft of the motor 371 is connected to the lower cleaning roller 33 via a spur gear assembly 373. In use, by setting the driving component 37 to use the motor 371 in conjunction with the spur gear assembly 373 and the meshing transmission gears 372, the lower cleaning roller 33 and the upper cleaning roller 34 are ensured to rotate stably in opposite directions, improving the cleaning effect.

In use, electromagnets 444 are fixedly installed on the top of both guide plate 442 and guide plate 443. The guide plate 442 and guide plate 443 are tilted in opposite directions to form a Z-shaped guide channel, which extends the falling path of the crushed material and ensures that the crushed material is in full contact with the guide plate. By setting electromagnets 444, the electromagnets 444 on the top of guide plate 442 and guide plate 443 generate magnetic force after being energized, which attracts metal impurities such as iron nails in the crushed material and prevents metal from entering the crushing part 46.

[0051] Combination Figures 1-13As shown, the fixed shell 45 includes a fixed plate 451 fixedly installed at the bottom of the guide shell 441 and fixedly connected to the support frame 41. Both sides of the fixed plate 451 are hinged with L-shaped sealing plates 452. When the free ends of the two sealing plates 452 are in contact, the top of the sealing plates 452 is in contact with the bottom of the guide shell 441. The fixed plate 451 is symmetrically hinged with drive rods three, which are respectively hinged to the two sealing plates 452. In use, the two L-shaped sealing plates 452 are controlled to rotate by the drive rods three. When closed, they are in contact with the bottom of the guide shell 441 to achieve sealed material guidance and prevent material leakage. When opened, they provide a channel for the lower cleaning roller 33 to enter the crushing component 46. The design of the free ends of the sealing plates 452 in contact ensures the sealing effect. The hinge structure of the drive rods three makes the opening and closing action stable and controllable, taking into account both the sealing performance of the material guidance and the convenience of equipment maintenance.

[0052] Combination Figures 1-13As shown, the crushing component 46 includes a crushing box 461, a limiting frame 462, a side baffle 463, an abrasive roller 464, a rotating joint 465, a guide hopper 467, and a negative pressure pipe 466. The crushing box 461 is fixedly installed on the fixing plate 451 between two sealing plates 452. The guide hopper 467 is fixedly installed on the fixing plate 451 below the second guide plate 443. The limiting frame 462 is fixedly installed on the top of the crushing box 461 below the guide hopper 467. The side of the limiting frame 462 away from the fixing plate 451 is open. A grinding roller 464 is fixedly installed on each of the two sealing plates 452. When the free ends of the side baffles 463 and the two sealing plates 452 are in contact, the two side baffles 463 are in contact and block the opening end of the limiting frame 462. An abrasive roller 464 is rotatably mounted on the crushing box 461 and inside it via a rotating shaft 4611. The top of the abrasive roller 464 extends to the inside of the limiting frame 462. A communicating cavity 4641 is opened inside the abrasive roller 464. Several communicating holes 4642, each communicating with the inside of the communicating cavity 4641, are opened on the outer wall of the abrasive roller 464. A communicating port, communicating with the inside of the communicating cavity 4641, is opened at the end of the rotating shaft 4611. A rotary joint 465 connected to the communication port is fixedly installed at the end of the 11. A negative pressure pipe 466 is fixedly installed at the end of the rotary joint 465. A second motor is fixedly installed on the crushing box 461. The output shaft of the second motor is connected to the rotating shaft 4611 through a spur gear assembly. The limiting frame 462 and the side baffle 463 cooperate to limit the crushed material and ensure the crushing effect between the grinding roller 464 and the crushing box 461. By setting the internal communication cavity 4641 of the grinding roller 464 to the external negative pressure pipe 466 through the rotary joint 465, the negative pressure makes the material smaller than the communication hole. Fine powder with a diameter of 4642 is sucked into the connecting cavity 4641 and then discharged onto the conveyor belt 411 through the negative pressure pipe 466, avoiding powder accumulation and improving crushing efficiency. The sealing plate 452 opens and the rear baffle 463 moves synchronously, removing the seal on the opening end of the limiting frame 462. Combined with the movement of the lower cleaning roller 33, the lower cleaning roller 33 can contact the surface of the abrasive roller 464, achieving a cleaning effect on the abrasive roller 464. At the same time, the negative pressure pipe 466 can simultaneously extract impurities generated during cleaning, ensuring the cleaning effect. By setting up the guide hopper 467, it is beneficial for the crushed material to fall accurately into the crushing box 461.

[0053] Combination Figures 1-13As shown, the air extraction component 22 includes a vent pipe 221, an exhaust fan 222, and a filter plate 223.

The other end of the vent pipe 221 is connected to the air inlet of the exhaust fan 222. The air guide component 23 is connected to the air outlet of the exhaust fan 222. During use, the filter plate 223 inside the negative pressure box 21 seals the vent hole, filtering out dust and impurities in the air and preventing impurities from entering the exhaust fan 222 and causing damage.

[0054] Combination Figures 1-13 As shown, one end of the lower cleaning roller 33 has an air guide cavity 331 extending into it, and the outer wall of the lower cleaning roller 33 has multiple air guide holes 332 that are all connected to the air guide cavity 331.

The other end of the air guide component 23 can be connected to the air guide cavity 331 and the air guide cavity 341. In use... When the exhaust fan 222 is in operation, the gas discharged by the exhaust fan 222 is guided by the air guide component 23 into the air guide chamber 331 of the lower cleaning roller 33 and the air guide chamber 341 of the upper cleaning roller 34 respectively. Then, it is blown onto the surface of the wood-plastic board through the air guide hole 332 and the air guide hole 342, blowing away the fine impurities after the roller brush has cleaned it, which greatly improves the cleanliness. In addition, the air guide chamber and the cleaning roller are integrated into the design, and the airflow jet direction is matched with the roller brush cleaning direction to form a composite cleaning mode of brushing and blowing, which improves the cleaning effect.

When the conical tube 2321 is inserted into the conical sleeve 2351, the unlocking element 6 unlocks the sealing element 5 to cancel the sealing of the conical tube 2321. In use, the corrugated tube 231 adapts to the displacement of the lower cleaning roller 33. The fitting insertion structure of the conical tube 2321 and the conical sleeve 2351 ensures the sealing performance when the first air guide box 232 and the second air guide box 235 are connected to avoid gas leakage. By setting the unlocking element 6 and the sealing element 5, when the first air guide box 232 moves away from the second air guide box 235, the sealing element 5 seals the conical tube 2321, thus achieving the sealing effect of the conical tube 2321.

The sealing block 52 is in contact with the sealing block 52. During use, the sealing block 5 and the spring telescopic rod 51 provide continuous elastic force to drive the sealing block 52 to fit tightly against the inner wall of the conical tube 2321, ensuring no gas leakage when the channel is blocked. The unlocking component 6 and the abutment post 61 are fixed in the air guide box 235. When the conical tube 2321 is inserted into the conical sleeve 2351, the abutment post 61 can accurately abut against the top of the sealing block 52 to unlock and ensure stable airflow.

[0058] Drive rod 4 142 controls the height of lifting frame 141, and drive rod 5 143 drives the third chain plate conveyor 15 to rotate. The extrusion pressure can be adjusted according to the thickness of wood-plastic board to ensure the crushing effect of soil clods and improve the adaptability of initial cleaning. The conveying end of conveyor belt 3 7 extends to the top of crushing shell 42 to realize the separate feeding and synchronous crushing of wood-plastic board scraps, expanding the application range of the equipment. By setting conveyor belt 2 411, which is located below negative pressure pipe 466, it receives the crushed fine powder and conveys it to the subsequent process, forming a complete crushing and discharge process and improving the continuity of processing.

[0059] Working principle and usage process of this invention:

[0060] When using:

[0061] S1: When crushing recycled outdoor strip-shaped wood-plastic composite board waste, control the exhaust fan 222, the first chain conveyor 12, the second chain conveyor 13, the third chain conveyor 15, and the conveyor belt 36 to start, feeding the recycled outdoor strip-shaped wood-plastic composite board onto the first chain conveyor 12. The first chain conveyor 12 conveys the strip-shaped wood-plastic composite board. During this process, control the drive rod 4 142 to move the lifting frame 141 downward along the telescopic rod 3, and drive the drive rod 5 143 to rotate the third chain conveyor 15 at the bottom of the lifting frame 141, thereby conveying the strip-shaped wood-plastic composite board through the third chain conveyor 36. The board conveyor 15 and the first chain conveyor 12 squeeze the surface of the outdoor strip wood-plastic composite board, thereby crushing the soil clods on the surface of the outdoor strip wood-plastic composite board into soil powder during the conveying process. During the conveying process of the strip wood-plastic composite board, the crushed soil powder falls downwards, and some of the soil powder falls directly into the negative pressure box 21 through the ventilation hole. When the exhaust fan 222 is working, it allows the outside air to circulate into the negative pressure box 21 through the ventilation hole. Some of the soil powder enters the negative pressure box 21 with the air flow, effectively reducing the situation where soil powder flies into the ambient air and reduces the ambient air quality.

[0062] During the conveying process of the strip-shaped wood-plastic composite board, when the strip-shaped wood-plastic composite board is moved between the second chain conveyor 13 and the third chain conveyor 15, it is conveyed by the second chain conveyor 13 and the third chain conveyor 15. When the end of the strip-shaped wood-plastic composite board moves to the inside of the support frame 31, the end of the strip-shaped wood-plastic composite board extends between the upper cleaning roller 34 and the lower cleaning roller 33. During this period, the control motor 371 is turned on, and the output shaft of the motor 371 rotates, which drives the lower cleaning roller 33 to rotate through the spur gear assembly 373. In turn, the two transmission gears 372 drive the upper cleaning roller 34 and the lower cleaning roller 33 to rotate in opposite directions. The rotation of the upper cleaning roller 34 and the lower cleaning roller 33 cleans the surface of the strip-shaped wood-plastic composite board. Furthermore, when the exhaust fan 222 is working and exhausts gas from its exhaust end, the gas flows through the corrugated pipe 231 into the first air guide box 232, and some of the gas flows through the conical pipe 2321 into the second air guide box 235, thereby flowing into the first air guide chamber 331 and the second air guide chamber 341 respectively, and then is discharged through multiple first air guide holes 332 and multiple second air guide holes 342 and blown onto the surface of the strip wood-plastic board, further improving the cleaning effect on the strip wood-plastic board and improving the cleanliness of the strip wood-plastic board; the strip wood-plastic board cleaned by the upper cleaning roller 34 and the lower cleaning roller 33 is guided to the two guide rollers 35, and then moved onto the first conveyor belt 36, thereby being transported by the first conveyor belt 36 to the top of the crushing shell 42 and falling downward into the crushing shell 42;

[0063] The two crushing rollers 43 of the waste crushing mechanism 4 rotate in opposite directions, the two electromagnets 444 are activated, and the second motor is activated. When the two crushing rollers 43 rotate in opposite directions, they crush the strip-shaped wood-plastic composite board that falls into the crushing shell 42 into small pieces. As the small pieces fall downwards, they land on the first guide plate 442 and the second guide plate 443 in the guide shell 441, and then slide down along the first guide plate 442 and the second guide plate 443 to the inside of the guide hopper 467, and then into the crushing box 461. The limiting frame 462 and the two side baffles 463 limit the wood-plastic composite board small pieces that fall into the crushing box 461. The output shaft of the second motor rotates, which drives the rotating shaft 4611 to rotate through the second spur gear assembly, so that the grinding roller 464 rotates in the crushing box 461, crushing the small pieces that fall between the crushing box 461 and the grinding roller 464. The material is crushed, and during this process, the air in the connecting cavity 4641 is extracted outward using the negative pressure pipe 466, creating a negative pressure in the connecting cavity 4641. The crushed material smaller than the diameter of the connecting hole 4642 between the crushing box 461 and the grinding roller 464 enters the connecting cavity 4641, and then flows with the air into the negative pressure pipe 466 and is discharged downward onto the second conveyor belt 411. The crushed powder is conveyed by the second conveyor belt 411, thus completing the crushing process of the recycled outdoor strip-shaped wood-plastic composite board waste. If there are iron nails left in the recycled outdoor strip-shaped wood-plastic composite board waste during installation, when the wood-plastic composite board crushed material falls onto the first guide plate 442 and the second guide plate 443, the electromagnets 444 at the top of the first guide plate 442 and the second guide plate 443 attract the iron nails, effectively preventing the iron nails from falling into the crushing box 461.

[0064] S2: When simultaneously crushing the scraps left over from the processing of wood-plastic composite boards, control the opening of conveyor belt 37 to feed the wood-plastic composite board scraps onto conveyor belt 37. Conveyor belt 37 transports the wood-plastic composite board scraps into the crushing shell 42. Similarly, the crushing effect of the wood-plastic composite board scraps can be achieved.

[0065] S3: When periodically cleaning the abrasive roller 464, the two driving rods 3 rotate the two sealing plates 452 on the fixed plate 451, making the side walls of the two sealing plates 452 flush with the side wall of the fixed plate 451, driving the two side baffles 463 to move synchronously, canceling the sealing of one side opening of the limiting frame 462. At this time, the control driving rods 1 325 and 2 326 drive the support seat 324 to move downward, and the air guide box 1 232 moves downward synchronously, causing the conical tube 2321 to move below the conical sleeve 2351. The spring telescopic rod 51 returns to its natural state, pushing the sealing block 52 to seal the inside of the conical tube 2321. When the lower cleaning roller 33 moves to below the lowest end of the conveyor belt 1 36, the electric slider 1 moves the moving seat 321 towards the support frame 41, and the motor 1 causes the hinge to move. Block 323 rotates on the hinge frame 322, so that the lower cleaning roller 33 faces the crushing box 461. The height position of the hinge frame 322 is adjusted by the drive rod 325, and then the lower cleaning roller 33 extends to the inner side of the limiting frame 462 and contacts the outer wall of the abrasive roller 464 through the drive rod 326. The motor 2 is turned on, so that the abrasive roller 464 rotates in the crushing box 461. The motor 371 is turned on, driving the lower cleaning roller 33 to rotate, so as to achieve the cleaning effect on the surface of the lower cleaning roller 33. At the same time, the exhaust fan 222 is turned on, and the gas flows into the air guide chamber 331 and is discharged through multiple air guide holes 332 and blown onto the abrasive roller 464. With the control of the negative pressure pipe 466 to simultaneously draw the air out of the connecting cavity 4641, the internal cleaning effect of the connecting hole 4642 is achieved.

[0066] After cleaning, the lower cleaning roller 33 is reset by the cooperation of the electric slider 1, drive rod 1 325 and drive rod 2 326. The conical tube 2321 is inserted into the conical sleeve 2351, so that the two transmission gears 372 mesh. The abutment post 61 is inserted into the conical tube 2321 and abuts against the top of the sealing block 52. The sealing block 52 is pressed down, causing the spring telescopic rod 51 to deform and cancel the sealing of the conical tube 2321, so that the equipment can carry out normal crushing operation.
