Description

Technical Field

[0001] The present invention relates to the technical field of crushing of wood-based panel waste, and particularly relates to a device and method for crushing and recycling wood-based panel waste. Background Art

[0002] Wood-based panel waste refers to various wastes generated during the production of wood-based panels, including sawdust, wood shavings, waste fibers, sanding powder, etc. A wood-based panel waste crushing and recycling device is a device used for recycling wood-based panel waste, and its main purpose is to convert waste into reusable resources through crushing and separation technologies.

[0003] The crushing and recycling of wood-based panel waste usually adopts mechanical physical separation methods, including dry and wet methods. The dry method mainly realizes the separation of metal and non-metal through steps such as crushing, screening, and air separation, while the wet method reduces pollution and improves the resource recovery rate through wet crushing and hydraulic shaking table separation.

[0004] For example, Chinese Patent No. CN211487880U discloses a wood-based panel edge crusher, which absorbs and filters the dust generated during the operation of the crusher, facilitating environmental protection, preventing dust from harming the environment, and at the same time facilitating the protection of the human body, improving safety and practicality; it includes a crushing chamber, four sets of legs, a guide plate, two sets of crushing shafts, two sets of crushing wheels, a first mounting plate, and a first motor. The front lower left, rear lower left, front lower right, and rear lower right ends of the crushing chamber are respectively connected to the tops of the four sets of legs. A first cavity is provided inside the crushing chamber, and a feeding port is communicated with the right end of the first cavity. 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 hopper, a second air pipe, a filter chamber, a filter screen, and a third air pipe.

[0005] However, there are still some deficiencies in the above crusher during actual use:

[0006] 1. When processing wood-based panel waste in the above prior art, a large amount of dust will be generated from the wood-based panel waste, and with the long-term processing of the wood-based panel waste, the dust will fill the working environment in large quantities, and some precision components of the equipment will be contaminated, and it will also cause harm to the nearby operators.

[0007] 2. Further, after the existing crusher crushes the product for a long time, it is necessary to stop the machine to replace the vulnerable parts inside it, and a large amount of time is required to lock and disassemble the bolts and nuts when replacing the vulnerable parts. Therefore, the replacement of vulnerable parts is not only frequent but also rather cumbersome, ultimately resulting in a decline in the crushing efficiency and production capacity of the crusher.

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

[0009] To solve the above problems, the present invention provides a device and method for crushing and recycling wood-based panel waste, adopting the following technical solutions:

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

[0015] Preferably, the telescopic adjusting member includes an activity slot opened inside the crushing roller. A connecting rod is installed in the activity slot of the crushing roller. Two adjusting rings are slidably installed on the connecting rod. A number of active wedge blocks are equally spaced and hinged on the outer wall of the adjusting ring. A passive wedge block abuts against the active wedge block. The passive wedge block is installed on the crushing hammer.

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

[0017] Preferably, the crushing size adjusting member includes a size adjusting screw rod rotatably connected to the crushing box. Two size adjusting blocks are screwed on the size adjusting screw rod. The bottom of the size adjusting block slidably abuts against the inner wall of the crushing box. A lifting block is installed on the top of the size adjusting block along the height direction. A crushing size adjusting plate is installed at one end of the lifting block away from the size adjusting block. The crushing size adjusting plate is slidably arranged at the bottom of the crushing cylinder.

[0018] Preferably, a plurality of adjustment grooves are equidistantly formed in the crushing size adjustment plate, and the adjustment grooves in the crushing size adjustment plate correspond to the blanking grooves on the crushing cylinder one by one, and the adjustment grooves and the blanking grooves are overlapped in a movable manner.

[0019] Preferably, a plurality of groups of impact tooth plates with different densities are arranged along the length direction of the inner wall of the crushing cylinder. A guiding column is installed in the crushing box, and a plurality of connecting plates are installed on the guiding column. A clamping member is clamped on the connecting plate, and the impact tooth plate is connected to the connecting plate through the clamping member.

[0020] A plurality of sealing blocks are also arranged on the guiding column and installed at both ends of the connecting plate.

[0021] Preferably, the clamping member includes passive racks equidistantly formed on one side of the connecting plate close to the impact tooth plate. A clamping groove is formed on one side of the impact tooth plate close to the connecting plate. An active rack is arranged in the clamping groove, and a clamping 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 close to the impact tooth plate. The trapezoidal block is slidably arranged in the clamping groove of the impact tooth plate. Pressing rods are abutted against two inclined surfaces of the trapezoidal block, and the pressing rods are slidably inserted through the impact tooth plate.

[0023] In a second aspect, the present application also provides a method for crushing and regenerating wood-based panel waste. The method for crushing and regenerating wood-based panel waste is as follows:

[0024] S1. Pretreatment: First, remove non-wood impurities in the wood-based panel waste and divide large pieces of waste into small pieces.

[0025] S2. Humidification treatment: Put the wood-based panel waste into a dust collector and spray a dust suppressant on the wood-based panel waste.

[0026] S3. Crushing treatment: Crush the humidified wood-based panel waste through a crusher to make it into granular crushed materials of a specified size.

[0027] S4. Collection treatment: The granular crushed materials are discharged from the bottom of the crushing cylinder for unified collection.

[0028] S5. Sorting and purification: Screen the granular crushed materials again to remove residual ferromagnetic metals and non-magnetic metals.

[0029] S6. Regeneration treatment: Physically shape the granular crushed materials, mix the purified wood fibers with an adhesive, and form a regenerated board through cold pressing.

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

[0031] 1. The wood-based panel waste is fed into the crushing cylinder through the feeding chute at the top of the crushing cylinder. The crushing hammers rotate. When they pass through the feeding chute of the crushing cylinder, the crushing hammers strike the wood-based panel waste from top to bottom; the kinetic energy is used to crush the wood-based panel waste, thus forming the first impact crushing. Then, with the cooperation of the counterattack tooth plate, the wood-based panel waste is repeatedly impacted and crushed, so that the crushed wood-based panel waste forms the second or multiple impact crushings. After multiple impact crushings, the wood-based panel waste can be turned into granular crushed materials of a specified size.

[0032] 2. The dust collector proposed in this application sprays the wood-based panel waste, so that the dust suppression liquid can be evenly adsorbed into the interior of the wood-based panel waste. When the crusher crushes it, the generation of dust can be effectively inhibited, and at the same time, the weight of the fine granular wood-based panel waste can be increased to prevent it from floating in the crushing box, thus effectively avoiding dust flying.

[0033] 3. This application also proposes a crushing size adjusting member. Through the crushing size adjusting member, the size of the discharging chute at the bottom of the crushing cylinder can be adjusted. When the wood-based panel waste in the crushing cylinder is crushed into particles smaller than the size of the discharging chute, the wood-based panel waste can be discharged from the discharging chute at the bottom of the crushing cylinder.

[0034] 4. This application also proposes a telescopic adjusting member. Through the telescopic adjusting member, the number of crushing hammers on the crushing roller is adjusted. The more the number of crushing hammers, the faster the speed of crushing the wood-based panel waste, and the higher the efficiency of crushing the wood-based panel waste into granular crushed materials of a specified size; on the contrary, the speed of crushing the wood-based panel waste is slow, and the efficiency of crushing the wood-based panel waste into granular crushed materials of a specified size is also low.

DETAILED DESCRIPTION

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

[0055] The embodiment of the present application discloses a device and method for crushing and regenerating artificial board waste, which is mainly used in the field of recycling and reusing artificial board waste. In the above-mentioned prior art, when artificial board waste is processed, the artificial board waste will generate a large amount of dust, and with the long-term processing of artificial board waste, a large amount of dust will be diffused in the working environment, and some precision parts of the equipment will be contaminated, and it will also cause damage to nearby operators.

[0056] Furthermore, after crushing the product for a long time, the existing crusher needs to be shut down to replace its internal wearing parts, and the replacement of wearing parts requires a lot of time to achieve the locking and disassembly of the bolts and nuts. As a result, the replacement of wearing parts is not only frequent but also cumbersome, which will eventually lead to a decrease in the crushing efficiency and production capacity of the crusher.

[0057] Therefore, the present application proposes a device for crushing and regenerating waste artificial board materials to solve the above problems.

[0058] Embodiment 1:

[0059] Reference Figure 1 As shown, a device for crushing and regenerating waste artificial board materials comprises a crushing box 1 for loading and crushing waste artificial board materials.

[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 wood-based panel waste to avoid generating a large amount of dust during the crushing process of the wood-based panel waste, and the crushing area mainly crushes the humidified wood-based panel waste into granular debris of the same size for subsequent reuse.

[0061] Refer to Figure 2 and Figure 3 As shown, the crusher 2 is arranged at the bottom of the crushing box 1. The crusher 2 includes two groups of crushing cylinders 20 symmetrically arranged in the crushing box 1. A crushing roller 21 is rotatably connected in the crushing cylinder 20. Crushing hammers 22 for crushing the wood-based panel waste are arranged on the crushing roller 21. A telescopic adjusting member 23 for adjusting the number of the crushing hammers 22 is further arranged between the crushing hammers 22 and the crushing roller 21.

[0062] The crushing hammers 22 and the counterattack tooth plates 30 correspond to each other. The crushing hammers 22 and the crushing roller 21 rotate, and then the wood-based panel debris is crushed into debris of the same size between the crushing hammers 22 and the counterattack tooth plates 30.

[0063] The bottom of the crushing cylinder 20 is provided with discharge slots 24 at equal intervals, and a crushing size adjusting member 25 for adjusting the size of the discharge slots 24 is further arranged at the bottom of the crushing cylinder 20.

[0064] When the debris is crushed into the specified size, the debris is discharged from the discharge slots 24 at the bottom of the crushing cylinder 20 until it is uniformly collected, and then it can be dried.

[0065] The dust collector 4 soaks the wood-based panel waste to avoid generating dust when the crusher 2 crushes it.

[0066] Refer to Figure 4 As shown, it is a schematic structural diagram of processing the wood-based panel waste in this application; specifically, a crushing motor 27 is installed on the crushing box 1 through a motor base. The output end of the crushing motor 27 is connected to the crushing roller 21 on one side, and a synchronous control belt 28 is jointly sleeved between the crushing rollers 21 on the two groups of crushing cylinders 20.

[0067] During specific implementation, the crushing motor 27 is started. The output end of the crushing motor 27 drives the two crushing rollers 21 to rotate in cooperation with the synchronous control belt 28. Crushing hammers 22 are arranged on the crushing rollers 21, so the crushing hammers 22 can rotate uniformly inside the crushing cylinder 20. At the same time, counterattack tooth plates 30 corresponding to the crushing hammers 22 are further arranged on the inner wall of the crushing cylinder 20.

[0068] Refer to Figure 5 and Figure 6As shown, a feeding groove 26 is provided at the top of the crushing cylinder 20. The wood-based panel waste is put into the crushing cylinder 20 through the feeding groove 26 at the top of the crushing cylinder 20. The crushing hammers 22 rotate. When they pass through the feeding groove 26 of the crushing cylinder 20, the crushing hammers 22 strike the wood-based panel waste from top to bottom; the kinetic energy is used to crush the wood-based panel waste, thus forming the first impact crushing. Then, with the cooperation of the counterattack tooth plate 30, the wood-based panel waste is repeatedly impacted and crushed, so that the crushed wood-based panel waste forms the second or multiple impact crushings. After multiple impact crushings, the wood-based panel waste can be turned into granular crushed materials of a specified size.

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

[0070] Furthermore, in order to improve the crushing efficiency of the wood-based panel waste, the present application also proposes a telescopic adjusting member 23. The number of the crushing hammers 22 on the crushing roller 21 is adjusted through the telescopic adjusting member 23. The more the number of the crushing hammers 22, the faster the speed of crushing the wood-based panel waste, and the higher the efficiency of crushing the wood-based panel waste into granular crushed materials of a specified size; on the contrary, the speed of crushing the wood-based panel waste is slow, and the efficiency of crushing the wood-based panel waste into granular crushed materials of a specified size is also low.

[0071] Refer to Figure 6 As shown, the telescopic adjusting member 23 includes a movable groove provided inside the crushing roller 21. A connecting rod 230 is installed in the movable groove of the crushing roller 21. Two groups of adjusting rings 231 are slidably installed on the connecting rod 230. A number of active wedge blocks 232 are equally spaced and hinged on the outer wall of the adjusting ring 231. A passive wedge block 234 abuts against the active wedge block 232, and the passive wedge block 234 is installed on the crushing hammer 22.

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

[0073] In the initial state, twelve groups of crushing hammers 22 are provided on the crushing roller 21, and six groups of the twelve groups of crushing hammers 22 are retracted into the inside of the crushing roller 21, while the other six groups of crushing hammers 22 extend out of the crushing roller 21, and the extended crushing rollers 21 and the retracted crushing rollers 21 are alternately distributed.

[0074] During specific implementation, the electric push rod 235 is activated. The output end of the electric push rod 235 controls and adjusts the ring 231 to move away from the electric push rod 235. At this time, the active wedge block 232 on the adjusting ring 231 squeezes the passive wedge block 234 on the crushing hammer 22 in the crushing roller 21, causing the crushing hammer 22 on the passive wedge block 234 to extend out of the crushing roller 21. At this time, all twelve groups of crushing hammers 22 extend out of the crushing roller 21. When the twelve groups of crushing hammers 22 crush the artificial board. Increasing the number of crushing hammers 22 can expand the contact area and impact frequency of the artificial board waste, thereby improving the crushing efficiency of the artificial board waste. When six groups of crushing hammers 22 crush the artificial board waste, the spacing between the crushing hammers 22 is large, and it can crush some artificial board waste with larger sizes, but its crushing efficiency for the artificial board waste is significantly lower than that of the twelve groups of crushing hammers 22 crushing the artificial board waste.

[0075] In addition, in order to adjust the size of the granular crushed material of the artificial board waste after crushing, the present application also proposes a crushing size adjusting member 25. Through the crushing size adjusting member 25, the size of the feeding slot 24 at the bottom of the crushing cylinder 20 can be adjusted. When the artificial board waste in the crushing cylinder 20 is crushed into particles smaller than the size of the feeding slot 24, the artificial board waste can be discharged from the feeding slot 24 at the bottom of the crushing cylinder 20.

[0076] Refer to Figure 7 and Figure 8 As shown, specifically, the crushing size adjusting member 25 includes a size adjusting screw rod 250 rotatably connected to the crushing box 1 through a bearing. Two size adjusting blocks 251 are screwed onto the size adjusting screw rod 250. The bottom of the size adjusting block 251 slides and abuts against the inner wall of the crushing box 1. A lifting block 252 is installed at the top of the size adjusting block 251 in the height direction. A crushing size adjusting plate 253 is installed at one end of the lifting block 252 away from the size adjusting block 251. The crushing size adjusting plate 253 is slidably arranged at the bottom of the crushing cylinder 20.

[0077] A number of adjusting slots 254 are equidistantly arranged on the crushing size adjusting plate 253, and the adjusting slots 254 on the crushing size adjusting plate 253 correspond to the feeding slots 24 on the crushing cylinder 20 one by one, and the adjusting slots 254 and the feeding slots 24 are overlapped and distributed movably.

[0078] It should be noted that in the initial state, the crushing size adjusting plate 253 is slidably installed at the bottom of the crushing cylinder 20, and the adjusting slots 254 on the crushing size adjusting plate 253 overlap with the feeding slots 24 at the bottom of the crushing cylinder 20. At this time, the feeding slot 24 of the crushing cylinder 20 is at the maximum size.

[0079] During specific implementation, when it is necessary to adjust the size of the blanking chute 24, rotate the size adjustment screw 250. The size adjustment screw 250 drives the size adjustment block 251 screwed to its upper end to move along the length direction of the crushing chamber 1 away from the crushing cylinder 20. At this time, the size adjustment block 251 cooperates with the lifting block 252 at its upper end to control 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 blanking chute 24, causing the size of the blanking 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 move closer to the crushing cylinder 20, the size of the blanking chute 24 gradually increases until it reaches the specified size and the crushing size adjustment plate 253 stops moving.

[0082] Embodiment 2: When the impact tooth plate 30 and the crushing hammer 22 crush the wood-based panel waste, the number of crushing hammers 22 can be adjusted as needed; similarly, the corresponding impact tooth plate 30 also needs to be adjusted accordingly.

[0083] Refer to Figure 9 、 Figure 10 and Figure 11 As shown, specifically, several groups of impact tooth plates 30 with different densities are provided along the length direction on the inner wall of the crushing cylinder 20. A guiding column 31 is installed in the crushing chamber 1. A number of connecting plates 34 are installed on the guiding column 31. A clamping member 32 is clamped and provided on the connecting plate 34. The impact tooth plate 30 is connected to the connecting plate 34 through the clamping member 32.

[0084] Sealing blocks 33 are also provided on the guiding column 31 and installed at both ends of the connecting plate 34.

[0085] It should be noted that there are two groups of guiding columns 31 in this application, and several groups of impact tooth plates 30 with different tooth densities are provided on the guiding column 31 through the clamping member 32. When it is necessary to adjust different impact tooth plates 30, pull the guiding column 31 to control the movement of the impact tooth plates 30 with different tooth densities on the guiding column 31 into the crushing cylinder 20. When the impact tooth plate 30 moves 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 tooth plate 30 is a vulnerable part. When the wood-based panel debris and some iron filings mixed therein impact the impact tooth plate 30, it will accelerate the wear of the impact tooth plate 30. Therefore, it is necessary to regularly replace the impact tooth plate 30. Refer to Figure 10 、 Figure 11 and Figure 12As shown in the figure, the clamping member 32 includes a passive rack 320 equidistantly arranged on one side of the connecting plate 34 close to the counterattack tooth plate 30. A clamping groove 321 is formed on one side of the counterattack tooth plate 30 close to the connecting plate 34. An active rack 322 is arranged in the clamping groove 321. A clamping spring 323 is installed between the active rack 322 and the counterattack tooth plate 30.

[0087] One end of the active rack 322 close to the counterattack tooth plate 30 is provided with a trapezoidal block 324. The trapezoidal block 324 is slidably arranged in the clamping groove 321 of the counterattack tooth plate 30. Pressing rods 325 are abutted against two inclined surfaces of the trapezoidal block 324. The pressing rods 325 are slidably arranged through the counterattack tooth plate 30.

[0088] During specific implementation, when replacing the counterattack tooth plate 30, press the two pressing rods 325 on the back side of the counterattack tooth plate 30. The two pressing rods 325 simultaneously extrude the inclined surfaces 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 integrally connected to the trapezoidal block 324 is separated 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 counterattack tooth plate 30 can be detached from the connecting plate 34 along the length direction of the connecting plate 34.

[0089] When a new counterattack tooth plate 30 needs to be replaced, press the pressing rods 325 on both sides of the new counterattack tooth plate 30 to retract the active rack 322 into the counterattack tooth plate 30. Then, the new counterattack tooth plate 30 can be slid along the length direction of the connecting plate 34 to the specified position of the connecting plate 34. Subsequently, release the pressing rods 325, and the active rack 322 abuts against the passive rack 320, realizing the quick clamping between the counterattack tooth plate 30 and the connecting plate 34.

[0090] After the counterattack tooth plate 30 is installed on the connecting plate 34 of the guide post 31, controlling the movement of the guide post 31 can replace the counterattack tooth plate 30 with different tooth densities. Similarly, the counterattack tooth plate 30 made of different materials can also be replaced to improve the efficiency and stability of the crushing of wood-based panel waste.

[0091] Embodiment 3:

[0092] Refer to Figure 13 and Figure 14As shown in the figure, on the basis of the first embodiment, in order to avoid a large amount of dust generated during the crushing of wood-based panel waste, the present application also proposes a dust collector 4. By spraying the wood-based panel waste with the dust collector 4, the dust suppression liquid can be evenly adsorbed into the interior of the wood-based panel waste. When the crusher 2 crushes it, the generation of dust can be effectively inhibited, and at the same time, the weight of the fine particulate wood-based panel waste can be increased to prevent it from floating in the crushing box 1. Specifically, the dust collector 4 includes a humidifying box 40 slidably installed along the length direction inside the crushing box 1. A humidifying groove is provided on one side of the humidifying box 40. A spray shower 41 is installed on the top of the humidifying box 40. The water mist of the spray shower 41 is sprayed into the interior of the humidifying box 40. A discharge port 42 for discharging the liquid sprayed by the spray shower 41 is opened at the bottom of the humidifying box 40.

[0093] One side of the humidifying box 40 is connected with a control push rod 43, and the control push rod 43 is arranged on the outer wall of the crushing box 1 through a bracket.

[0094] It should be noted that a storage tank for storing the dust suppression liquid, which is known in the art, is installed on the spray shower 41.

[0095] During specific implementation, the control push rod 43 is started. The output end of the control push rod 43 drives the humidifying box 40 to move into the interior of the crushing box 1. Until the humidifying box 40 reaches the designated position, the wood-based panel waste is thrown into the interior of the crushing box 1. Then the wood-based panel waste enters the humidifying box 40. Subsequently, the spray shower 41 is started, and the spray shower 41 sprays the dust suppression liquid downward. Then the dust suppression liquid enters the interior of the humidifying box 40. And as the dust suppression liquid is sprayed from top to bottom, it will contact the wood-based panel waste stored in the interior of the humidifying box 40 and be absorbed by the wood-based panel waste.

[0096] Refer to Figure 14 、 Figure 15 and Figure 16 As shown in the figure, in order to control the liquid outlet time of the spray shower 41, the present application also mentions a linkage plate 45. Specifically, a number of linkage springs 44 are arranged at equal intervals at the bottom of the humidifying box 40. A linkage plate 45 is jointly installed on the linkage springs 44, and the linkage plate 45 is slidably arranged inside the humidifying box 40 along the height direction of the humidifying box 40. A linkage rope 46 is installed on one side of the linkage plate 45. One end of the linkage rope 46 away from the linkage plate 45 extends along the inner wall of the humidifying box 40 towards the direction of the spray shower 41. An opening and closing block 47 is installed in the water spray port of the spray shower 41 through an opening and closing spring 48. The opening and closing spring 48 is arranged in the water spray port of the spray shower 41. One 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 springs 44, so that the linkage plate 45 is in a suspended state.

[0098] During specific implementation, when the wood-based panel waste enters the interior of the humidifying box 40, the wood-based panel waste presses down on the linkage plate 45. After the wood-based panel waste accumulates 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 the other side thereof to move downward, thereby causing the blocked opening and closing block 47 on the spray shower 41 to separate from the water spray opening of the spray shower 41, opening the water spray opening of the spray shower 41, spraying the dust suppression liquid on the wood-based panel waste, enabling the wood-based panel waste to absorb the dust suppression liquid, and increasing its water content.

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

[0100] Look again Figure 14 and Figure 16 As shown in the figure, the humidifying box 40 is provided with a linkage card slot 49 along its horizontal direction. An automatic material taking plate 50 is installed in the crushing box 1. The linkage card slot 49 of the humidifying box 40 and the automatic material taking plate 50 on the crushing box 1 are on the same horizontal straight line. During the movement of the humidifying box 40, the linkage card slot 49 opened at its upper end is movably inserted into the automatic material taking plate 50.

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

[0102] After the wood-based panel waste has absorbed the dust suppression liquid, control the push rod 43 to contract. At this time, control the push rod 43 to drive the humidifying box 40 away from the crushing box 1. At this time, the automatic material taking plate 50 squeezes the wood-based panel waste accumulated on the linkage plate 45 of the humidifying box 40, causing it to move away from the humidifying box 40 and enter the humidifying area of the crushing box 1, and then fall into the two crushing cylinders 20 for crushing treatment.

[0103] Refer to Figure 17 As shown in the figure, the wood-based panel waste crushing and regeneration treatment method is as follows:

[0104] S1. Pretreatment: First, non-wood impurities such as metal, plastic, and glass in the wood-based panel waste need to be removed. For large pieces of waste, they are divided into small 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 interior of the crushing box 1. Until the humidification box 40 reaches the specified position, throw the wood-based panel waste into the interior of the crushing box 1. Then the wood-based panel waste enters the humidification box 40. Subsequently, the spray shower 41 is started, and the spray shower 41 sprays the dust suppression liquid downward. Then the dust suppression liquid enters the interior of the humidification box 40. And as the dust suppression liquid is sprayed from top to bottom, it will contact the wood-based panel waste stored in the interior of the humidification box 40 and be absorbed by the wood-based panel waste.

[0106] After the wood-based panel waste has absorbed the dust suppression liquid, the control push rod 43 contracts. 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 taking plate 50 squeezes the wood-based panel waste piled on the linkage plate 45 of the humidification box 40, so that it moves away from the humidification box 40 and enters the humidification area of the crushing box 1 and falls into the two crushing cylinders 20.

[0107] S3. Crushing treatment: Then start the crushing motor 27. The output end of the crushing motor 27 cooperates with the synchronous control belt 28 to drive the two crushing rollers 21 to rotate, and the crushing hammers 22 rotate. When the wood-based panel waste passes through the feeding groove 26 of the crushing cylinder 20, the crushing hammers 22 strike the wood-based panel waste from top to bottom; use kinetic energy to crush the wood-based panel waste, thus forming the first impact crushing. Then, with the cooperation of the counterattack tooth plate 30, the wood-based panel waste is repeatedly impact-crushed, so that the crushed wood-based panel waste forms a second or multiple impact crushings. After multiple impact crushings, the wood-based panel waste can be turned into granular crushed materials of the specified size.

[0108] When the wood-based panel waste passes through multiple crushings, the granular crushed materials are separated from the crushing box 1 through the feeding slot 24 at the bottom of the crushing cylinder 20 and are collected uniformly.

[0109] S4. Collection treatment: The crushed granular crushed materials are discharged from the crushing cylinder 20 of the crushing box 1 and then collected uniformly.

[0110] S5. Sorting and purification: Screen the crushed and collected granular crushed materials again to remove residual ferromagnetic metals and non-magnetic metals.

[0111] S5. Recycling treatment: Physically shape and heat-treat the granular crushed materials, mix the purified wood fibers with adhesives, and cold-press them into core boards.

[0112] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
