Description

Technical Field

[0001] The present invention relates to the technical field of sheet production, and particularly to a raw material pretreatment device and method for the production of humidity-adjusting sheets. Background Art

[0002] In the manufacture of humidity-adjusting sheets, bamboo and wood fibers have become the core raw materials for enhancing the humidity adjustment ability of materials due to their natural porous structure, high specific surface area, and adjustable moisture absorption performance. Bamboo and wood fibers interact with water molecules in the environment through their internal pore structure and surface polar groups (such as hydroxyl groups) to achieve a dynamic balance of moisture absorption and desorption. Before mixing the bamboo and wood fiber raw materials, in order to facilitate the transportation and storage of bamboo and wood fibers, they are generally pressed to form block-shaped or rod-shaped raw materials of unified specifications. In the actual production process, it is necessary to decompose them in advance, convert the pressed bamboo and wood fibers into a powder state, and then add diatomaceous earth, activated carbon, adhesives, regulators, and reinforcing materials for mixed production.

[0003] The Chinese patent document (Publication No.: CN1213031A) discloses a humidity-adjusting board for interior wall and ceiling decoration. This humidity-adjusting board utilizes the characteristics of wood materials and has excellent humidity adjustment functions. Moreover, when this humidity-adjusting board is used as the interior wall decoration material in a museum, it can appropriately adjust the humidity inside the museum even if the constant temperature and humidity machine is stopped for a certain period of time. To achieve the above object, the present invention provides a humidity-adjusting board for interior wall decoration and a humidity-adjusting board for ceiling decoration. The humidity-adjusting board for interior wall decoration is characterized in that a soft fiber board with the density of wood-based fibers compressed to 330 - 380 kg / cm3 and a hard fiber board with the density of wood-based fibers compressed to 680 - 730 kg / cm3 and having many grooves are adhesively bonded in a double layer, and an air circulation path is formed between the soft fiber board and the hard fiber board. The humidity-adjusting board for ceiling decoration is characterized in that the density of its wood fibers is compressed to 630 - 670 kg / cm3, and concave and convex portions that can be mutually fitted are formed on both sides. In the drying process, the fibrous material coated with the resin adhesive in the above-mentioned adhesive coating process is continuously passed through a dryer to dry it to a moisture content of 8 - 13%. In the cooling process, each humidity-adjusting board compressed to a specified thickness through the above-mentioned forming process is put into a cooler to completely harden the resin adhesive coated on the fibrous material.

[0004] During the production of humidity-adjusting boards, when bamboo and wood fibers are used as the main raw materials, they often face the problem of metal impurity pollution. These metal impurities mainly come from the collection, transportation, and preliminary processing of bamboo and wood raw materials. When bamboo is cut, iron tool fragments (such as saw blades) may be mixed in. During the wood processing, metal parts such as nails and screws may remain. Rust, steel wires, etc. may also be mixed in during transportation and storage. If these metal impurities are not removed in time, it will directly affect the quality of the finished humidity-adjusting boards, resulting in uneven local strength and uneven surface of the boards. Even in a humid environment, metal oxidation will occur, rust spots will appear, reducing the aesthetic appearance and service life of the boards. When using an electromagnet to separate magnetic metals from raw material powder, the electromagnet will collide with the metal and be damaged. The impact of metal particles (especially high-hardness ferromagnetic materials) will cause scratches on the surface of the electromagnet or peeling of the protective layer (such as insulating paint, wear-resistant coating). Long-term wear may expose the internal coil, leading to short circuits or accelerating oxidation and corrosion. Summary of the Invention

[0016] Preferably, a method for processing using the raw material pretreatment device for humidity-conditioning plate production comprises the following steps:

[0017] S1. Place the pressed bamboo fiber sticks or blocks in the top material plate, start the motor, and the motor drives the rotating shaft to rotate. The first wedge block at the edge of the support plate and the second wedge block inside the upper cover form a shearing process, so that the bamboo fiber pressed sticks or blocks inside are accelerated to be broken into segments, and the broken segments enter the crushing cylinder;

[0019] S3, the rotating shaft is meshed with the first gear through the second gear, and the first gear is meshed with the inner gear ring, driving the rotating disk to rotate inside the first ring body, so that the bamboo fiber powder is evenly distributed on the rotating disk;

[0020] S4, start the electromagnet, the turntable drives the bamboo fiber powder to rotate under the isolation component, the electromagnet absorbs the magnetic metal in the powder through the isolation component, and the magnetic metal moves to the storage tank along with the isolation component;

[0021] S5. The bamboo and wood fiber powder after magnetic metal separation is discharged from the powder outlet to complete the pretreatment. Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The innovative design of setting an isolation component outside the electromagnet in the present invention solves two major technical problems, namely, the damage of the electromagnet and the efficient separation and transmission of magnetic metal objects, at the same time. The isolation component can not only block the direct wear and impact of magnetic metals on the electromagnet, but also ensure that the magnetic field can pass through smoothly to adsorb metal impurities. By driving the isolation component to operate continuously through a rotating mechanism, the dynamic separation and transportation of metal impurities from the bamboo and wood fiber powder are realized. The metal impurities are adsorbed on the surface of the isolation component and move with it. When they leave the magnetic field range of the electromagnet, they naturally fall off and enter the storage tank. This structural design not only extends the service life of the electromagnet, greatly reduces the equipment maintenance cost and downtime, but also forms an uninterrupted separation and transmission process through the continuous movement of the isolation component, ensuring the efficient removal of metal impurities and providing a purer raw material basis for the production of humidity-adjusted boards. The creativity of this design lies in the organic combination of the protection function and the separation function, and solves the contradiction between static protection and efficient separation in a dynamic operation mode.

[0023] 2. The innovative design in Embodiment 1 of the present invention proposes a new solution to the two major technical problems of electromagnet protection and complete separation of magnetic metals. By setting an isolation belt outside the electromagnet, the effective protection of the electromagnet is realized. At the same time, a tipping unit is designed at the bottom of the powder, so that the magnetic metal substances buried in the bamboo and wood fiber powder are fully exposed and effectively separated. Specifically, the isolation component is made of a non-magnetic wear-resistant material, forming a physical barrier to the electromagnet and blocking the direct contact between magnetic metals and the electromagnet. The magnetic field generated by the electromagnet acts on the magnetic metals through the isolation component. At the same time, the turning rod arranged under the turntable turns the powder from the bottom during the rotation process, bringing the magnetic metal impurities originally buried at the bottom or in the middle of the powder to the surface, fully exposing them within the range of the magnetic field action, and then being adsorbed by the isolation component and transported to the collection area. This dual structural design is technically breakthrough and creative: on the one hand, the combination of the isolation component and the electromagnet breaks the design limitation of directly exposing the electromagnet in the traditional way, and solves the problem of short service life of the electromagnet from the source; on the other hand, the bottom turning mechanism and the upper adsorption mechanism work together to form a three-dimensional separation system, completely overcoming the technical bottleneck of incomplete separation of deep metal impurities in traditional planar magnetic separation.

[0024] 3. Embodiment 2 of the present invention solves two key technical problems of electromagnet protection and complete separation from magnetic metals through an innovative structural combination. The second electromagnet is arranged on the outer periphery of the balance cylinder, and the whole system is installed inside the annular channel, forming an efficient device integrating protection and separation functions. Specifically, when the system operates, the pivot drives the end plate to rotate, causing the arc plate to form a protective barrier outside the electromagnet, effectively preventing direct contact between the magnetic metal and the electromagnet, and fundamentally avoiding damage to the electromagnet caused by friction, impact, or dust accumulation. At the same time, the arc plate has freedom of movement, and in cooperation with the eccentrically designed support shaft, the torsion spring at the end of the support shaft provides just the right flexible support force. Through components such as the L-shaped plate, abutting block, and spring, a precise periodic interaction system is formed with the convex on the outer periphery of the end plate. When the arc plate rotates above the second receiving groove, under the action of the spring, the abutting block will move towards the arc plate and push the arc plate to rotate and unfold, causing the adsorbed metal impurities to fall into the second receiving groove under the action of gravity. When the end plate rotates, the convex pushes the ejector rod and the abutting block to move away from the arc plate together, and the arc plate resets and closes under the action of the torsion spring. The arc plate at the top is opened and closed in sequence to automatically collect the magnetic metal. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Embodiment 1

[0041] As Figures 1-9 shown, a raw material pretreatment device for the production of humidity-adjusting plates includes a crushing cylinder 11, an upper cover 12 and a base 25. A bracket 15 is installed at the bottom of the base 25. A motor 40 is provided at the bottom end of the base 25. The output end of the motor 40 is installed with a rotating shaft 18. The rotating shaft 18 penetrates through the base 25 and extends into the crushing cylinder 11. A support frame 20 is fixedly provided at the top of the crushing cylinder 11. The rotating shaft 18 is rotatably installed in the support frame 20, and a crushing rod 19 is installed on the rotating shaft 18. The base 25 is a cavity structure. The base 25 includes an inclined body 16, a first ring body 26 and a convex column 27. The top ends of the first ring body 26 and the convex column 27 are fixedly connected to the bottom end of the inclined body 16. There is an annular channel between the convex column 27 and the first ring body 26. A powder inlet 17 is provided on the inclined body 16. The powder inlet 17 communicates with the crushing cylinder 11 and the annular channel. A powder outlet 14 is provided on one side of the first ring body 26. A turntable 28 is provided inside the annular channel. The turntable 28 is connected to the rotating shaft 18 through a transmission component. A magnetic metal separation component is provided above the annular channel.

[0042] A top material plate 13 is provided at the top of the upper cover 12. The top material plate 13 is of an annular cylindrical structure. When the bamboo and wood fiber pressing block is placed therein, it plays a stabilizing role and provides space for fragmentation. The support frames 20 are all fixedly installed on the cover body 21. The rotating shaft 18 is installed in the cover body 21 through a bearing.

[0043] The working process of the device in this embodiment is as follows: After putting the pressed block of bamboo and wood fiber into the feeding port on the crushing cylinder 11, start the motor 40. The motor 40 drives the rotating shaft 18 to rotate, driving the crushing rod 19, the support plate 22 at the top of the rotating shaft 18 and the first wedge 23 to rotate. The rotating first wedge 23 and the fixed second wedge 24 form a relatively fast movement to fragment the pressed block of bamboo and wood fiber. After fragmentation, it enters the inside of the crushing cylinder 11, and the crushing rod 19 crushes the fragmented pressed block; after crushing, it forms powder, which enters the annular channel in the base 25 through the powder inlet 17 and lands on the turntable 28. The rotating shaft 18 drives the turntable 28 to rotate through the transmission component. The powder is driven by the turntable 28 to pass under the magnetic metal separation component in sequence. The magnetic metal separation component separates the rotating powder on the turntable 28, and finally places the separated magnetic metal inside the first storage groove 39. This device effectively solves the pollution problem caused by metal impurities mixed in the bamboo and wood fiber during collection, transportation and processing to the production of humidity-adjusted boards, improves the production quality of humidity-adjusted boards, extends the service life of the production equipment for humidity-adjusted boards, saves energy consumption during the production process, reduces production costs, and meets the quality requirements and environmental protection needs of modern industrial production for humidity-adjusted boards.

[0044] Further, the transmission component includes a first gear 37, a second gear 38 and an internal gear ring 36. The second gear 38 is installed on the rotating shaft 18; a guide ring groove is formed inside the first ring body 26; the turntable 28 includes an upper and a lower fixed second ring body and a third ring body. The second ring body is arranged adjacent to the inner circle of the third ring body. The inner circle of the second ring body is sleeved on the convex column 27, and the outer circumference of the third ring body is rotatably installed in the guide ring groove. The inner circle of the third ring body is fixedly provided with the internal gear ring 36; the second gear 38 meshes with the first gear 37, and the first gear 37 meshes with the internal gear ring 36 to drive the turntable 28 to rotate inside the first ring body 26.

[0045] See Figure 5 , when the motor 40 drives the rotating shaft 18 to rotate, the rotating shaft 18 drives the second gear 38 to rotate. The second gear 38 meshes and drives the first gear 37, and the first gear 37 meshes and drives the internal gear ring 36. The internal gear ring 36 and the turntable 28 rotate together. The third ring body at the lower part of the turntable 28 is located in the annular channel and is rotatably arranged. When the powder inside the crushing cylinder 11 lands on the third ring body at the lower part of the turntable 28, it rotates together and passes under the magnetic metal separation component, realizing the rapid separation of magnetic metal in the powder.

[0046] Furthermore, the magnetic metal separation component is an isolation belt structure, which includes a first electromagnet 41, a first roller 31, a second roller 34 and an isolation belt 33. The first roller 31 and the second roller 34 are located on both sides above the loop. The isolation belt 33 is sleeved on the outside of the first roller 31 and the second roller 34. A first receiving groove 39 is provided on the convex column 27 below the isolation belt 33. A second pulley is provided at one end of the first roller 31, and a tipping bucket unit is provided at one end of the second roller 34; the first electromagnet 41 is fixedly connected to the inner wall of the base 25 and is located inside the isolation belt 33; the transmission shaft on the first gear 37 extends to the top of the convex column 27, and the first bevel gear 29 is installed after the transmission shaft is connected to the first changing gear box. The first bevel gear 29 meshes with the second bevel gear 30, and a first pulley is provided on the gear shaft of the second bevel gear 30. The first pulley is connected to the second pulley through the first belt 32.

[0047] See also Figure 6 , Figure 7 and Figure 8 When the device in this embodiment is running, the turntable 28 drives the bamboo fiber powder to rotate and pass under the isolation belt 33. The first electromagnet 41 generates a magnetic field to act on the magnetic metal impurities in the powder, and adsorbs them on the outer surface of the isolation belt 33. As the first belt 32 drives the isolation belt 33 to rotate, the adsorbed metal impurities move with the isolation belt 33, leave the magnetic field range of the first electromagnet 41, and fall off into the first receiving groove 39 for collection; the isolation belt 33 is arranged on the surface of the electromagnet to avoid collision between the metal and the electromagnet, to avoid the impact of metal particles (especially high-hardness ferromagnetic materials) causing scratches on the surface of the electromagnet or peeling of the protective layer (such as insulating paint, wear-resistant coating), to slow down wear or accelerate oxidation corrosion, to protect the internal circuit, to ensure the performance of the electromagnet, and to extend the service life.

[0048] The first roller 31 and the second roller 34 are both installed inside the hollow cavity of the base 25 through a bearing seat.

[0049] Further, the tipping bucket unit is located in the hollow cavity of the first ring body 26, and the tipping bucket unit includes a second belt 35, a fourth pulley and a tipping rod 46.

A fifth pulley is arranged at the transmission end of the fourth bevel gear 43; a power shaft 45 is passed through the hollow cavity of the first ring body 26 and the annular groove, and a sixth pulley is arranged at the end of the power shaft 45 located in the cavity, and the fifth pulley and the sixth pulley are connected by the third belt 44; two groups of eccentric components are rotatably arranged on the inner wall of the annular groove, and the eccentric components include a rotating plate 47, an eccentric shaft 48 is installed on the rotating plate 47, a transverse plate 49 is rotatably arranged between the two eccentric shafts 48, and a tipping rod 46 is fixed on the transverse plate 49. The end of the power shaft 45 located in the annular groove is fixedly connected to one of the rotating plates 47, and the other rotating plate 47 is rotatably installed on the inner wall of the annular groove.

[0050] See also Figure 9 The power is converted through the pulley at one end of the second roller 34, the steering gear and the two sets of belts, and the power is transmitted to the power shaft 45. When the power shaft 45 drives the rotating plate 47 to rotate, the eccentric shaft 48 away from the center of the rotating plate 47 drives the cross plate 49 to move up and down, and at the same time drives the turning rod 46 to move up and down, disturbing or lifting the bamboo and wood fiber powder, exposing the magnetic metal inside the powder to the magnetic force range of the first electromagnet, thereby increasing the adsorption range and further promoting the separation of the metal inside the powder.

[0051] Furthermore, transmission teeth are provided on the first roller 31 , the second roller 34 and the inner ring of the isolation belt 33 , and the isolation belt 33 is meshed with the outer circumference of the first roller 31 and the second roller 34 through the transmission teeth.

[0052] See also Figure 8 Transmission teeth are arranged on the first roller 31, the second roller 34 and the inner ring of the isolation belt 33 to ensure that there is no slipping during the transmission process, to ensure the stable transmission of the second roller 34, and to further transmit the power to the dump unit. The device uses one power source to provide multi-level power output, simplifies the device, saves space and reduces equipment costs.

[0053] Furthermore, a support plate 22 is fixed to one end of the rotating shaft 18 away from the motor 40, a first wedge block 23 is fixed to the edge of the support plate 22, and a plurality of second wedge blocks 24 are arranged in an array above the first wedge block 23. The second wedge blocks 24 are fixed inside the upper cover 12, and the first wedge block 23 and the second wedge block 24 have overlapping sections along the axial projection.

[0054] See also Figure 2, when the device is working, the motor 40 drives the rotating shaft 18 to rotate, driving the support plate 22 and the first wedge block 23 to rotate synchronously. The rotating first wedge block 23 and the fixed second wedge block 24 periodically form a cutting action, generating a wedge-shaped cutting force with relative movement through the overlapping section between the two, and performing a preliminary fragmentation process on the bamboo and wood fiber pressing blocks put into the crushing cylinder 11, so that the large pressing blocks are divided into smaller fragments, reducing the workload of the subsequent crushing rod 19, improving the crushing efficiency, avoiding incomplete crushing or jamming caused by oversized pressing blocks, extending the service life of the equipment, reducing energy consumption, and improving production efficiency. The design of this wedge block combination makes full use of the mechanical cutting principle to form an efficient material pre-treatment mechanism, providing a good material basis for the subsequent fine crushing and metal separation processes.

[0055] It should be noted that the centrifugal force of the support plate 22 causes the internal bamboo and wood pressing blocks to move towards the directions of the first wedge block 23 and the second wedge block 24, accelerating the fragmentation process.

[0056] A method for processing using a raw material pre-treatment device for producing humidity-adjusted boards includes the following steps:

[0057] S1. Place the pressed bamboo and wood fiber rods or blocks in the top material plate 13 to provide a fragmentation space through the top material plate 13; start the motor 40, the motor 40 drives the rotating shaft 18 to rotate, and at the same time, the first wedge block 23 at the edge of the support plate 22 fixedly provided at the end of the rotating shaft 18 away from the motor 40 cooperates with the second wedge block 24 inside the upper cover 12, and the centrifugal force of the support plate 22 causes the internal bamboo and wood pressing blocks to move towards the directions of the first wedge block 23 and the second wedge block 24, accelerating the fragmentation process;

[0058] S2. The crushing rod 19 on the rotating shaft 18 crushes the bamboo and wood fiber rods or blocks, and the crushed bamboo and wood fiber powder enters the hollow cavity inside the base 25 through the powder inlet 17 and falls onto the turntable 28;

[0059] S3. The rotating shaft 18 meshes with the first gear 37 through the second gear 38, and the first gear 37 then meshes with the internal gear ring 36 to drive the turntable 28 to rotate inside the first ring body 26, making the bamboo and wood fiber powder evenly distributed on the turntable 28;

[0060] S4. Start the first electromagnet 41, the turntable 28 drives the bamboo and wood fiber powder to pass under the isolation belt 33, the first electromagnet 41 adsorbs the magnetic metals in the powder through the isolation belt 33, and the magnetic metals move with the isolation belt 33 and naturally fall off into the first storage groove 39 after leaving the magnetic field range of the first electromagnet 41; at the same time, the second roller 34 drives the tipping unit to work, and the tipping rod 46 moves up and down to turn the powder from the bottom, bringing the magnetic metal impurities buried at the bottom or middle of the powder to the surface and fully exposing them within the magnetic field range;

[0061] S5. After the magnetic metal separation, the bamboo and wood fiber powder is discharged from the powder outlet 14, completing the pretreatment.

[0062] Example 2

[0063] Different from Example 1, the magnetic metal separation component is an isolation plate structure. The isolation plate structure includes two end plates 51 arranged oppositely. A pivot 50 is fixedly arranged at the center of the two end plates 51. Both ends of the pivot 50 are installed on the first ring body 26 through bearings. One end of the pivot 50 is connected to the first gear 37 through a conduction unit; several support shafts 62 are arranged in an array at the edges of the two end plates 51. An arc plate 53 is sleeved on the support shafts 62. The support shafts 62 are eccentrically arranged relative to the arc plate 53. A torsion spring 63 is arranged at the end of the support shaft 62; a balance cylinder 59 is sleeved on the pivot 50. A second receiving groove 60 is opened at the top of the balance cylinder 59. Several second electromagnets 61 are arranged on the outer periphery of the balance cylinder 59; an opening and closing unit is arranged above the second receiving groove 60.

[0064] See Figure 10 , the balance cylinder 59 is sleeved on the pivot 50. When the pivot 50 rotates, the balance cylinder 59 remains stationary. A balance weight is arranged at the bottom of the balance cylinder 59. A second receiving groove 60 is opened at the top of the balance cylinder 59, so that the center of gravity of the balance cylinder 59 moves downward to be in a stable state; wherein the pivot 50 is fixedly connected to the end plate 51, the end plate 51 is fixedly connected to the support shaft 62, and the support shaft 62 is rotatably connected to the arc plate 53.

[0065] When the pivot 50 rotates, it drives the two end plates 51, the support shafts 62 and the arc plate 53 to rotate together. The balance cylinder 59 remains stationary. The second electromagnets 61 arranged on the outer periphery of the balance cylinder 59 adsorb the magnetic metal onto the arc plate 53. When the arc plate 53 and the magnetic metal rotate together to the opening and closing unit at the top, the opening and closing unit abuts against and pushes away the arc plate 53 below. No electromagnet is arranged directly below this arc plate. Under the action of gravity, the magnetic metal falls into the second receiving groove 60.

[0066] It should be noted that the pivot 50 adopts a hollow structure. Conductive slip rings are arranged on the pivot 50 inside and outside the arc plate. The external power supply is introduced into the second electromagnets inside the arc plate through the conductive slip rings. Among them, the conductive slip ring is a prior art, and the working principle is not described in detail here.

[0067] Furthermore, the opening and closing unit includes an L-shaped plate 54, the top horizontal plate of the L-shaped plate 54 is fixedly connected to the inner wall of the base 25, a sliding groove is provided on the vertical plate of the L-shaped plate 54, a contact block 56 is slidably arranged in the sliding groove, a guide rod 57 is fixed on the top of the contact block 56, the guide rod 57 passes through the top horizontal plate of the L-shaped plate 54 and a limit block is fixed at the end, a spring 58 is sleeved on the guide rod 57, and the spring 58 pushes and squeezes the contact block 56 toward the direction close to the arc plate 53; a plurality of top protrusions 52 are arranged on the outer periphery of the end plate 51 corresponding to the array of the arc plate 53, and a top rod 55 is fixed on the side of the contact block 56 close to the top protrusion 52.

[0068] See also Figure 10 and Figure 11 Under normal circumstances, under the action of spring 58, spring 58 pushes abutment block 56 toward the direction of arc plate 53 and squeezes the arc plate below, so that the arc plate rotates around support shaft 62 and is inclined. At this time, the bottom of push rod 55 abuts against the upper edge of end plate 51. There is no electromagnet directly below this arc plate. Under the action of gravity, the magnetic metal falls into the second receiving groove 60. When end plate 59 rotates, top protrusion 52 pushes push rod 55 to move upward, driving abutment block 56 to move upward, so that the arc plate is reset and closed, which is beneficial for abutment block 56 to contact with the next arc plate, and the cycle of opening and closing.

[0069] Furthermore, the transmission unit includes a second direction-changing gear box (not shown in the figure) and a third direction-changing gear box (not shown in the figure), the transmission shaft on the first gear 37 extends to the top of the boss 27, the transmission shaft is connected to the input end of the second direction-changing gear box, one end of the pivot 50 is connected to the output end of the third direction-changing gear box, and the output end of the second direction-changing gear box is connected to the input end of the third direction-changing gear box through a belt and a pulley.

[0070] When the first gear 37 rotates, its transmission shaft transmits power to the second direction-changing gearbox (not shown) at the top of the boss 27. The second direction-changing gearbox converts the vertical rotational motion into the horizontal rotational motion, and drives the belt to rotate through the pulley at its output end; the belt transmits power to the pulley at the input end of the third direction-changing gearbox (not shown). The third direction-changing gearbox changes the rotation direction again, and its output end drives the pivot 50 to rotate. This design of double direction-changing gearboxes combined with belt drive solves the problem of power transmission under complex spatial layout, realizes the power transmission path from the vertical axis to the horizontal axis and then to a specific angle, and enables the isolation plate structure to rotate at a suitable speed and direction.

[0071] The method for processing using a raw material pretreatment device for producing humidity-conditioning panels comprises the following steps:

[0072] S1. Place the pressed bamboo and wood fiber rods or blocks into the ejector plate 13 to provide a space for fragmentation through the ejector plate 13. Start the motor 40. The motor 40 drives the rotating shaft 18 to rotate. At the same time, the first wedge block 23 at the edge of the support plate 22 fixedly installed at the end of the rotating shaft 18 away from the motor 40 cooperates with the second wedge block 24 inside the upper cover 12. Use the centrifugal force of the support plate 22 to move the internal bamboo and wood pressing blocks towards the direction of the first wedge block 23 and the second wedge block 24 to accelerate the fragmentation process.

[0073] S2. The crushing rod 19 on the rotating shaft 18 crushes the bamboo and wood fiber rods or blocks. The crushed bamboo and wood fiber powder enters the hollow cavity inside the base 25 through the powder inlet 17 and falls onto the turntable 28.

[0074] S3. The rotating shaft 18 meshes with the first gear 37 through the second gear 38, and the first gear 37 then meshes with the internal gear ring 36 to drive the turntable 28 to rotate inside the first ring body 26, so that the bamboo and wood fiber powder is evenly distributed on the turntable 28.

[0075] S4. The second electromagnet 61 adsorbs the magnetic metals in the powder through the arc-shaped plate 53. The pivot shaft 50 drives the end plate 51 to rotate, and the arc-shaped plate 53 forms a protective barrier outside the electromagnet. When the arc-shaped plate 53 rotates above the second receiving groove 60, under the action of the spring 58, the abutting block 56 pushes the arc-shaped plate 53 to rotate and unfold, so that the adsorbed metal impurities fall into the second receiving groove 60 under the action of gravity. When the end plate 51 rotates, the top protrusion 52 pushes the ejector rod 55 to move away from the arc-shaped plate 53, and the arc-shaped plate 53 resets and closes under the action of the torsion spring 63, and the opening and closing cycle of the next arc-shaped plate is carried out in turn.

[0076] S5. The bamboo and wood fiber powder after magnetic metal separation is discharged from the powder outlet 14 to complete the pretreatment.
