Description

Technical Field

[0001] This invention relates to the technical field of crushing waste wood-based panels, and particularly to a device and method for crushing and regenerating waste wood-based panels. Background Technology

[0002] Wood-based panel waste refers to various wastes generated during the production of wood-based panels, including sawdust, shavings, waste fibers, sanding powder, etc. Wood-based panel waste crushing and recycling equipment is a device used to recycle and reuse wood-based panel waste. Its main purpose is to transform waste into reusable resources through crushing and separation technology.

[0003] The crushing and recycling of waste wood-based panels typically employs mechanical and physical separation methods, including dry and wet processes. Dry processes primarily separate metals from non-metals through crushing, screening, and air classification, while wet processes reduce pollution and increase resource recovery rates through wet crushing and hydraulic shaking table separation.

[0004] For example, Chinese patent CN211487880U discloses a wood-based panel edge strip crusher, which absorbs and filters the dust generated during the operation of the crusher, thus protecting the environment and preventing dust from causing harm to the environment. At the same time, it also protects the human body, improving safety and practicality. It includes a crushing chamber, four sets of support legs, a guide plate, two sets of crushing shafts, two sets of crushing wheels, a first mounting plate, and a first motor. The lower left front side, lower left rear side, lower right front side, and lower right rear side of the crushing chamber are respectively connected to the top of the four sets of support legs. The crushing chamber has a first cavity inside, and the right end of the first cavity is connected to a feed inlet. The left end of the guide plate is connected to the right end of the crushing chamber. It also includes a second mounting plate, a second motor, a suction pump, a first air pipe, a suction bucket, a second air pipe, a filter chamber, a filter screen, and a third air pipe.

[0005] However, the aforementioned crusher still has some shortcomings in actual use:

[0006] 1. In the above-mentioned prior art, when processing artificial board waste, the artificial board waste will generate a large amount of dust. As the artificial board waste is processed for a long time, the dust will spread in the working environment, which will cause some precision parts of the equipment to be contaminated and will also cause damage to nearby workers.

[0007] 2. Furthermore, after a long period of crushing, existing crushers need to be shut down to replace the vulnerable parts inside. Replacing these parts requires a significant amount of time to tighten and loosen bolts and nuts, resulting in frequent and cumbersome replacements. Ultimately, this leads to a decrease in the crusher's crushing efficiency and production capacity.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing crushers. Summary of the Invention

[0009] To address the aforementioned problems, this invention provides a device and method for crushing and recycling waste wood-based panels, employing the following technical solution:

[0010] In a first aspect, this application provides a device for crushing and recycling waste wood-based panels, including a crushing box for loading and crushing waste wood-based panels.

[0011] The crusher is located at the bottom of the crushing box. The crusher includes two sets of crushing cylinders symmetrically arranged in the crushing box. A crushing roller is rotatably connected inside the crushing cylinder. The crushing roller is equipped with a crushing hammer for crushing the artificial board waste.

[0012] The upper end of the crushing cylinder is provided with a feed chute, and the bottom of the crushing cylinder is provided with a discharge chute at equal intervals. The bottom of the crushing cylinder is also provided with a crushing size adjustment component for adjusting the size of the discharge chute.

[0013] The crushing cylinder is equipped with impact teeth.

[0014] Preferably, a crushing motor is mounted on the crushing box via a motor mount. The output end of the crushing motor is connected to a crushing roller on one side. A synchronous control belt is provided between the crushing rollers on the two sets of crushing cylinders. Two reversing wheels are rotatably mounted on the outer wall of the crushing box in the middle of the synchronous control belt.

[0015] Preferably, the telescopic adjustment component includes a movable groove inside the crushing roller, a connecting rod installed in the movable groove of the crushing roller, two sets of adjusting rings slidably installed on the connecting rod, and a plurality of active wedges hinged at equal intervals on the outer wall of the adjusting rings, with a passive wedge abutting against the active wedge, and the passive wedge mounted on the breaker hammer.

[0016] Two sets of electric push rods are installed on the connecting rod, and the two sets of electric push rods are respectively connected to the corresponding adjusting rings.

[0017] Preferably, the crushing size adjustment component includes a size adjustment screw rotatably connected to the crushing box, two size adjustment blocks screwed onto the size adjustment screw, the bottom of the size adjustment blocks sliding against the inner wall of the crushing box, a lifting block installed on the top of the size adjustment blocks along the height direction, and a crushing size adjustment plate installed at the end of the lifting block away from the size adjustment blocks, the crushing size adjustment plate being slidably disposed at the bottom of the crushing cylinder.

[0018] Preferably, the crushing size adjustment plate is provided with a plurality of adjustment slots at equal intervals, and the adjustment slots of the crushing size adjustment plate correspond one-to-one with the feeding slots on the crushing cylinder, and the adjustment slots and the feeding slots are distributed in an overlapping manner.

[0019] Preferably, the inner wall of the crushing cylinder is provided with several sets of impact teeth of different densities along its length direction, the crushing box is equipped with a guide column, the guide column is equipped with several connecting plates, and the connecting plates are snapped with snap-fit ​​parts to connect the impact teeth to the connecting plates.

[0020] The guide post is also equipped with several sealing blocks installed at both ends of the connecting plate.

[0021] Preferably, the snap-fit ​​component includes passive racks evenly spaced on the side of the connecting plate near the impact tooth plate, a snap-fit ​​groove is provided on the side of the impact tooth plate near the connecting plate, an active rack is provided in the snap-fit ​​groove, and a snap-fit ​​spring is installed between the active rack and the impact tooth plate.

[0022] Preferably, a trapezoidal block is installed at one end of the active rack near the impact tooth plate. The trapezoidal block is slidably disposed in the snap-fit ​​groove of the impact tooth plate. A pressing rod is abutted on the two inclined surfaces of the trapezoidal block, and the pressing rod is slidably disposed on the impact tooth plate.

[0023] Secondly, this application also provides a method for crushing and recycling waste wood-based panels, as follows:

[0024] S1. Pre-treatment: First, remove non-wood impurities from the waste wood-based panels and divide large pieces of waste into smaller pieces.

[0025] S2. Humidification treatment: Put the waste wood-based panels into the dust collector and spray the waste wood-based panels with dust-suppressing liquid.

[0026] S3. Crushing process: The humidified artificial board waste is crushed by a crusher to produce granular material of a specified size.

[0027] S4. Collection and processing: The granular crushed material is discharged from the bottom of the crushing cylinder for unified collection;

[0028] S5. Sorting and purification: The granular crushed material is screened again to remove residual ferromagnetic and non-magnetic metals;

[0029] S6. Recycling process: Physically shape the granular crushed material, mix the purified wood fibers with adhesives, and then cold-press them into recycled boards.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Waste wood-based panels are fed into the crushing cylinder through the feed chute at the top of the crushing cylinder. The crushing hammer rotates and, as it passes through the feed chute of the crushing cylinder, it strikes the waste wood-based panels from top to bottom. The kinetic energy is used to crush the waste wood-based panels, thus forming the first impact crushing. Then, with the cooperation of the impact tooth plate, the waste wood-based panels are repeatedly impacted and crushed, so that the crushed waste wood-based panels undergo a second or multiple impact crushing. After multiple impact crushing, the waste wood-based panels can be turned into granular crushed materials of a specified size.

[0032] Second, the dust collector proposed in this application sprays the artificial board waste, so that the dust suppressant can be evenly adsorbed into the interior of the artificial board waste. When the crusher crushes it, it can effectively suppress the generation of dust, and at the same time increase the weight of the fine particulate artificial board waste, preventing it from floating in the crushing box, thereby effectively preventing dust from flying.

[0033] Third, this application also proposes a crushing size adjustment component, which can adjust the size of the feed chute at the bottom of the crushing cylinder. When the artificial board waste in the crushing cylinder is crushed into particles smaller than the size of the feed chute, the artificial board waste can be discharged from the feed chute at the bottom of the crushing cylinder.

[0034] Fourth, this application also proposes a telescopic adjustment component to adjust the number of crushing hammers on the crushing roller. The more crushing hammers there are, the faster the artificial board waste can be crushed, and the higher the efficiency of crushing the artificial board waste into granular materials of a specified size. Conversely, the slower the crushing speed of the artificial board waste, the lower the efficiency of crushing the artificial board waste into granular materials of a specified size.

Detailed Implementation

[0054] The following combination Figures 1-17 This application will be described in further detail.

[0055] This application discloses a device and method for crushing and recycling engineered wood waste, mainly applied in the field of engineered wood waste recycling. In the prior art, the processing of engineered wood waste generates a large amount of dust, and prolonged processing leads to a large amount of dust permeating the working environment, contaminating precision parts of the equipment, and potentially harming nearby workers.

[0056] Furthermore, after a prolonged period of crushing, existing crushers require shutdown to replace their internal wear parts. Replacing these parts takes a significant amount of time, including tightening and loosening bolts and nuts. Consequently, the replacement of wear parts is not only frequent but also cumbersome, ultimately leading to a decrease in the crusher's crushing efficiency and production capacity.

[0057] Therefore, this application proposes a device for crushing and recycling waste wood-based panels to solve the above problems.

[0058] Example 1:

[0059] Reference Figure 1 As shown, a device for crushing and recycling waste wood-based panels includes a crushing box 1 for loading and crushing waste wood-based panels.

[0060] The interior of the crushing box 1 is divided into two areas: one side is the dust removal area and the other side is the crushing area. The dust removal area mainly humidifies the artificial board waste to prevent the artificial board waste from generating a lot of dust during the crushing process. The crushing area mainly crushes the humidified artificial board waste into uniform granular fragments, which are easy to reuse later.

[0061] See Figure 2 and Figure 3 As shown, the crusher 2 is located at the bottom of the crushing box 1. The crusher 2 includes two sets of crushing cylinders 20 symmetrically arranged in the crushing box 1. A crushing roller 21 is rotatably connected inside the crushing cylinder 20. The crushing roller 21 is equipped with a crushing hammer 22 for crushing artificial board waste. A telescopic adjustment component 23 for adjusting the number of crushing hammers 22 is also provided between the crushing hammer 22 and the crushing roller 21.

[0062] The breaker 22 and the impact toothed plate 30 correspond to each other. The breaker 22 and the crushing roller 21 rotate, and then the artificial board debris is crushed into fragments of the same size between the breaker 22 and the impact toothed plate 30.

[0063] The bottom of the crushing cylinder 20 is provided with equal-spaced feed troughs 24, and the bottom of the crushing cylinder 20 is also provided with crushing size adjustment components 25 for adjusting the size of the feed troughs 24.

[0064] Once the debris is crushed to the specified size, it is discharged from the feed chute 24 at the bottom of the crushing cylinder 20 until it is collected and then dried.

[0065] Dust collector 4 soaks the artificial board waste to prevent dust from being generated when crusher 2 crushes it.

[0066] Reference Figure 4 The diagram shown is a schematic diagram of the structure for processing waste wood-based panels in this application. Specifically, a crushing motor 27 is installed on the crushing box 1 via a motor base. The output end of the crushing motor 27 is connected to a crushing roller 21 on one side. A synchronous control belt 28 is provided between the crushing rollers 21 on the two sets of crushing cylinders 20.

[0067] In practice, the crushing motor 27 is started. The output end of the crushing motor 27, together with the synchronous control belt 28, drives the two crushing rollers 21 to rotate. The crushing rollers 21 are equipped with crushing hammers 22, so the crushing hammers 22 can rotate at a constant speed inside the crushing cylinder 20. At the same time, the inner wall of the crushing cylinder 20 is also equipped with impact tooth plates 30 corresponding to the crushing hammers 22.

[0068] See Figure 5 and Figure 6As shown, a feed chute 26 is provided at the top of the crushing cylinder 20. The waste wood-based panels are fed into the crushing cylinder 20 through the feed chute 26 at the top of the crushing cylinder 20. The crushing hammer 22 rotates and hits the waste wood-based panels from top to bottom when it passes through the feed chute 26 of the crushing cylinder 20. The waste wood-based panels are crushed by kinetic energy, thus forming the first impact crushing. Then, with the cooperation of the impact tooth plate 30, the waste wood-based panels are repeatedly impacted and crushed, so that the crushed waste wood-based panels form a second or multiple impact crushing. After multiple impact crushing, the waste wood-based panels can be turned into granular crushed materials of a specified size.

[0069] After the waste wood-based panels are crushed multiple times, the granular crushed material is separated from the crushing box 1 through the feed chute 24 at the bottom of the crushing cylinder 20 and collected uniformly.

[0070] Furthermore, in order to improve the efficiency of crushing wood-based panel waste, this application also proposes a telescopic adjustment member 23, which adjusts the number of crushing hammers 22 on the crushing roller 21. The more crushing hammers 22 there are, the faster the wood-based panel waste can be crushed, and the higher the efficiency of crushing the wood-based panel waste into granular materials of a specified size. Conversely, the slower the crushing speed of the wood-based panel waste, the lower the efficiency of crushing the wood-based panel waste into granular materials of a specified size.

[0071] See Figure 6 As shown, the telescopic adjustment component 23 includes a movable groove inside the crushing roller 21. A connecting rod 230 is installed in the movable groove of the crushing roller 21. Two sets of adjusting rings 231 are slidably installed on the connecting rod 230. Several active wedges 232 are hinged at equal intervals on the outer wall of the adjusting rings 231. A passive wedge 234 abuts against the active wedge 232. The passive wedge 234 is installed on the breaker hammer 22.

[0072] Two sets of electric push rods 235 are installed on the connecting rod 230, and the two sets of electric push rods 235 are respectively connected to the corresponding adjusting rings 231.

[0073] In the initial state, the crushing roller 21 is provided with twelve sets of crushing hammers 22, and six sets of crushing hammers 22 are retracted into the interior of the crushing roller 21, while the other six sets of crushing hammers 22 extend out of the crushing roller 21, and the extended crushing roller 21 and the retracted crushing roller 21 are alternately distributed.

[0074] In practice, the electric push rod 235 is activated, and its output controls the adjusting ring 231 to move away from the push rod 235. At this time, the active wedge block 232 on the adjusting ring 231 squeezes the passive wedge block 234 on the crusher 22 within the crushing roller 21, causing the crusher 22 on the passive wedge block 234 to extend out of the crushing roller 21. At this point, all twelve sets of crushers 22 extend out of the crushing roller 21. The twelve sets of crushers 22 then crush the engineered wood product. Increasing the number of crushers 22 expands the contact area and impact frequency of the engineered wood waste, thereby improving the crushing efficiency. When six sets of crushers 22 crush the engineered wood waste, the spacing between them is large, allowing for the crushing of some larger pieces of engineered wood waste; however, the crushing efficiency is significantly lower than that of twelve sets of crushers 22.

[0075] In addition, in order to adjust the size of the granular crushed material of the crushed wood-based panel waste, this application also proposes a crushing size adjustment component 25. The crushing size adjustment component 25 can adjust the size of the bottom feed chute 24 of the crushing cylinder 20. When the wood-based panel waste in the crushing cylinder 20 is crushed into particles smaller than the size of the feed chute 24, the wood-based panel waste can be discharged from the bottom feed chute 24 of the crushing cylinder 20.

[0076] Reference Figure 7 and Figure 8 As shown, specifically, the crushing size adjustment component 25 includes a size adjustment screw 250 rotatably connected to the crushing box 1 via a bearing. Two size adjustment blocks 251 are screwed onto the size adjustment screw 250. The bottom of the size adjustment blocks 251 slides against the inner wall of the crushing box 1. A lifting block 252 is installed on the top of the size adjustment blocks 251 along the height direction. A crushing size adjustment plate 253 is installed at the end of the lifting block 252 away from the size adjustment blocks 251. The crushing size adjustment plate 253 is slidably disposed at the bottom of the crushing cylinder 20.

[0077] The crushing size adjustment plate 253 has several adjustment slots 254 at equal intervals, and the adjustment slots 254 of the crushing size adjustment plate 253 correspond one-to-one with the feeding slots 24 on the crushing cylinder 20, and the adjustment slots 254 and the feeding slots 24 are distributed in an overlapping manner.

[0078] It should be noted that, in the initial state, the crushing size adjustment plate 253 is slidably installed at the bottom of the crushing cylinder 20, and the adjustment groove 254 on the crushing size adjustment plate 253 overlaps with the discharge groove 24 at the bottom of the crushing cylinder 20. At this time, the discharge groove 24 of the crushing cylinder 20 is at its maximum size.

[0079] In practice, when it is necessary to adjust the size of the feeding trough 24, the size adjustment screw 250 is rotated. The size adjustment screw 250 drives the size adjustment block 251 screwed to its upper end to move away from the crushing cylinder 20 along the length of the crushing box 1. At this time, the size adjustment block 251, together with the lifting block 252 at its upper end, controls the crushing size adjustment plate 253 to slide along the bottom of the crushing cylinder 20.

[0080] When the size adjustment block 251 and the lifting block 252 move away from the crushing cylinder 20, the crushing size adjustment plate 253 covers the feeding chute 24, causing the size of the feeding chute 24 to gradually decrease until it reaches the specified size and the crushing size adjustment plate 253 stops moving.

[0081] When the size adjustment block 251 and the lifting block 252 approach the crushing cylinder 20, the size of the feeding chute 24 gradually increases until it reaches the specified size and stops moving the crushing size adjustment plate 253.

[0082] Example 2: When the impact toothed plate 30 and the breaker hammer 22 crush the artificial board waste, the number of breaker hammers 22 can be adjusted as needed; similarly, the corresponding impact toothed plate 30 also needs to be adjusted accordingly.

[0083] Reference Figure 9 , Figure 10 and Figure 11 As shown, specifically, the inner wall of the crushing cylinder 20 is provided with several sets of impact teeth 30 of different densities along its length direction. A guide column 31 is installed in the crushing box 1. Several connecting plates 34 are installed on the guide column 31. A snap-fit ​​member 32 is snapped on the connecting plate 34. The impact teeth 30 and the connecting plate 34 are connected by the snap-fit ​​member 32.

[0084] Several sealing blocks 33 are also installed on both ends of the connecting plate 34 on the guide column 31.

[0085] It should be noted that this application has two sets of guide posts 31, and the guide posts 31 are provided with several sets of impact tooth plates 30 with different tooth densities through the snap-fit ​​parts 32. When it is necessary to adjust different impact tooth plates 30, the guide posts 31 are pulled to control the impact tooth plates 30 with different tooth densities on the guide posts 31 to move into the crushing cylinder 20. At the same time as the impact tooth plates 30 move into the crushing cylinder 20, the sealing blocks 33 block both sides of the crushing cylinder 20 to ensure that the crushing cylinder 20 is in a sealed state.

[0086] The impact toothed plate 30 is a wear part. When particleboard fragments and iron filings embedded in them impact the impact toothed plate 30, the wear will be accelerated. Therefore, the impact toothed plate 30 needs to be replaced regularly. (See reference...) Figure 10 , Figure 11 and Figure 12As shown, the snap-fit ​​component 32 includes passive racks 320 that are equally spaced on the side of the connecting plate 34 near the counter-attack toothed plate 30. The counter-attack toothed plate 30 has a snap-fit ​​groove 321 on the side near the connecting plate 34. An active rack 322 is provided in the snap-fit ​​groove 321. A snap-fit ​​spring 323 is installed between the active rack 322 and the counter-attack toothed plate 30.

[0087] A trapezoidal block 324 is installed at one end of the active rack 322 near the impact tooth plate 30. The trapezoidal block 324 is slidably disposed in the snap-fit ​​groove 321 of the impact tooth plate 30. A pressing rod 325 is abutted on the two inclined surfaces of the trapezoidal block 324. The pressing rod 325 is slidably disposed on the impact tooth plate 30.

[0088] In practice, when replacing the counter-attack toothed plate 30, press the two pressing rods 325 on the back side of the counter-attack toothed plate 30. The two pressing rods 325 simultaneously squeeze the inclined surface of the trapezoidal block 324, causing the trapezoidal block 324 to move away from the connecting plate 34. When the trapezoidal block 324 moves away from the connecting plate 34, the active rack 322 integrated on the trapezoidal block 324 separates from the passive rack 320 on the connecting plate 34. At this time, the active rack 322 and the passive rack 320 are separated, and the counter-attack toothed plate 30 can be removed from the connecting plate 34 along the length of the connecting plate 34.

[0089] When a new counter-attack toothed plate 30 needs to be replaced, press the pressing rods 325 on both sides of the new counter-attack toothed plate 30 to retract the active rack 322 into the counter-attack toothed plate 30. Then, slide the new counter-attack toothed plate 30 along the length of the connecting plate 34 to the designated position on the connecting plate 34. Then release the pressing rods 325, and the active rack 322 will abut against the passive rack 320, thus achieving a quick snap-fit ​​between the counter-attack toothed plate 30 and the connecting plate 34.

[0090] After the impact tooth plate 30 is installed on the connecting plate 34 on the guide column 31, the impact tooth plate 30 with different tooth densities can be replaced by controlling the movement of the guide column 31. Similarly, impact tooth plates 30 of different materials can also be replaced to improve the efficiency and stability of crushing artificial board waste.

[0091] Example 3:

[0092] Reference Figure 13 and Figure 14As shown, based on Embodiment 1, in order to avoid generating a large amount of dust during the crushing of artificial board waste, this application also proposes a dust collector 4. The dust collector 4 sprays the artificial board waste, so that the dust suppressant liquid can be evenly adsorbed into the interior of the artificial board waste. When the crusher 2 crushes it, it can effectively suppress the generation of dust and increase the weight of the fine particulate artificial board waste, preventing it from floating in the crushing box 1. Specifically, the dust collector 4 includes a humidification box 40 that is slidably installed in the crushing box 1 along the length direction. A humidification trough is provided on one side of the humidification box 40. A spray nozzle 41 is installed on the top of the humidification box 40. The water mist from the spray nozzle 41 is sprayed into the humidification box 40. The bottom of the humidification box 40 is provided with a discharge port 42 for the liquid sprayed by the spray nozzle 41 to be discharged.

[0093] A control push rod 43 is connected to one side of the humidification box 40, and the control push rod 43 is mounted on the outer wall of the crushing box 1 via a bracket.

[0094] It should be noted that the spray nozzle 41 is equipped with a storage tank that is known to be used for storing dust suppressant.

[0095] In practice, the control push rod 43 is activated, and the output end of the control push rod 43 drives the humidification box 40 to move into the crushing box 1 until the humidification box 40 reaches the designated position. Then, the artificial board waste is thrown into the crushing box 1. The artificial board waste then enters the humidification box 40. Subsequently, the spray nozzle 41 is activated, and the spray nozzle 41 sprays dust suppression liquid downwards. The dust suppression liquid then enters the humidification box 40. As the dust suppression liquid is sprayed from top to bottom, it comes into contact with the artificial board waste stored inside the humidification box 40 and is absorbed by the artificial board waste.

[0096] Reference Figure 14 , Figure 15 and Figure 16 As shown, in order to control the liquid output time of the spray head 41, this application also mentions a linkage plate 45; specifically, a number of linkage springs 44 are arranged at equal intervals at the bottom of the humidification box 40, and a linkage plate 45 is installed on the linkage springs 44. The linkage plate 45 is slidably disposed inside the humidification box 40 along the height direction of the humidification box 40. A linkage rope 46 is installed on one side of the linkage plate 45. The end of the linkage rope 46 away from the linkage plate 45 extends along the inner wall of the humidification box 40 toward the spray head 41. An opening and closing block 47 is installed in the spray nozzle of the spray head 41 through an opening and closing spring 48. The opening and closing spring 48 is disposed in the spray nozzle of the spray head 41. The end of the linkage rope 46 away from the linkage plate 45 is connected to the opening and closing block 47.

[0097] In the initial state, the linkage plate 45 is supported by the linkage spring 44, so that the linkage plate 45 is in a suspended state.

[0098] In practice, when the waste wood-based panels enter the humidification box 40, the waste wood-based panels press down on the linkage plate 45. When the waste wood-based panels accumulate to a certain amount, its weight is greater than the elastic force of the linkage spring 44, causing it to press down on the linkage plate 45. When the linkage plate 45 moves downward, it pulls the linkage rope 46, causing the linkage rope 46 to drive the opening and closing block 47 connected to its other side to move downward, thereby causing the blocked opening and closing block 47 on the spray nozzle 41 to separate from the spray nozzle of the spray nozzle 41, so that the spray nozzle of the spray nozzle 41 opens, allowing the dust suppression liquid to be sprayed on the waste wood-based panels, so that the waste wood-based panels absorb the dust suppression liquid and increase its moisture content.

[0099] When crushing it at this time, the generation of dust can be effectively avoided.

[0100] Let's look again. Figure 14 and Figure 16 As shown, the humidification box 40 has a linkage slot 49 along its horizontal direction, and the crushing box 1 is equipped with an automatic material handling plate 50. The linkage slot 49 of the humidification box 40 and the automatic material handling plate 50 on the crushing box 1 are on the same horizontal straight line. During the movement of the humidification box 40, the linkage slot 49 at its upper end is movably connected to the automatic material handling plate 50.

[0101] In the initial state, the automatic material handling plate 50 is installed in the humidification zone of the crushing box 1. When the humidification box 40 moves into the crushing box 1, the automatic material handling plate 50 enters the linkage slot 49 of the humidification box 40.

[0102] After the wood-based panel waste has absorbed the dust suppression liquid, the control push rod 43 retracts. At this time, the control push rod 43 moves the humidification box 40 away from the crushing box 1. The automatic material handling plate 50 then squeezes the wood-based panel waste accumulated on the linkage plate 45 of the humidification box 40, causing it to move away from the humidification box 40 and enter the humidification zone of the crushing box 1, where it falls into the two crushing cylinders 20 for crushing.

[0103] See Figure 17 The method for crushing and recycling waste wood-based panels is shown below:

[0104] S1. Pre-treatment: First, non-wood impurities such as metal, plastic, and glass need to be removed from the waste wood-based panels. Large pieces of waste should be broken into smaller pieces.

[0105] S2. Humidification treatment: Start the control push rod 43. The output end of the control push rod 43 drives the humidification box 40 to move into the crushing box 1. After the humidification box 40 reaches the designated position, the artificial board waste is thrown into the crushing box 1. Then the artificial board waste enters the humidification box 40. Subsequently, the spray nozzle 41 is started. The spray nozzle 41 sprays dust suppression liquid downward. Then the dust suppression liquid enters the humidification box 40. As the dust suppression liquid is sprayed from top to bottom, it will come into contact with the artificial board waste stored inside the humidification box 40 and be absorbed by the artificial board waste.

[0106] After the wood-based panel waste has finished absorbing the dust suppression liquid, the control push rod 43 retracts. At this time, the control push rod 43 drives the humidification box 40 away from the crushing box 1. At this time, the automatic material handling plate 50 squeezes the wood-based panel waste accumulated on the linkage plate 45 of the humidification box 40, so that it moves away from the humidification box 40 and enters the humidification zone of the crushing box 1, and falls into the two crushing cylinders 20.

[0107] S3. Crushing process: Then start the crushing motor 27. The output end of the crushing motor 27, together with the synchronous control belt 28, drives the two crushing rollers 21 to rotate and the crushing hammer 22 to rotate. When the artificial board waste passes through the feed chute 26 of the crushing cylinder 20, the crushing hammer 22 hits the artificial board waste from top to bottom; using kinetic energy to crush the artificial board waste, thus forming the first impact crushing. Then, with the cooperation of the impact tooth plate 30, the artificial board waste is repeatedly impacted and crushed, so that the crushed artificial board waste forms a second or multiple impact crushing. After multiple impact crushing, the artificial board waste can be turned into granular crushed material of a specified size.

[0108] After the waste wood-based panels are crushed multiple times, the granular crushed material is separated from the crushing box 1 through the feed chute 24 at the bottom of the crushing cylinder 20 and collected uniformly.

[0109] S4. Collection and processing: The crushed granular material is fed into the crushing cylinder 20 of the crushing box 1 and then collected uniformly.

[0110] S5. Sorting and purification: The crushed and collected granular material is screened again to remove residual ferromagnetic and non-magnetic metals.

[0111] S5. Regeneration process: Physically shape and heat-treat the granular crushed material, mix the purified wood fibers with adhesive, and cold-press them into core boards.

[0112] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
