[Technical Field]

[0001] The present invention is in the field of board technology, and more particularly relates to an apparatus and process for producing natural fiber-filled materials. [Background technology]

[0002] Planks are flat rectangular sheets of material made to standard sizes and used in the building industry as wall, ceiling or floor components, and often refer to forged, rolled or cast metal plates, but also include wood planks, furniture planks, building planks, engineered planks and wood board materials, although it is well known that planks are often manufactured using equipment for producing natural fiber filled materials.

[0003] However, existing equipment for producing natural fiber filled materials still has certain defects when used. First, existing equipment for producing natural fiber filled materials often simply uses natural ventilation to dissipate heat from the control box on the hydraulic press, but the low heat dissipation effect of natural ventilation causes a problem of low heat dissipation efficiency of the control box.

[0004] Next, existing devices for producing natural fiber filled materials often use hydraulic presses to press-mold mixed fiber felt, which has the problem of high resistance to expansion and contraction of the hydraulic cylinder over long periods of use due to factors such as material friction between the cylinder and the telescopic rod. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION In order to solve the above problems, the present invention aims to provide an apparatus and process for producing natural fiber filling materials that solves the problems described in the background art above. [Means for solving the problem]

The rotary shaft is rotatably connected to the top plate, and the top plate is slidably connected to the scraper blade, which is slidably connected to the filter screen and the mounting plate. A semiconductor cooling sheet is provided to cool the air. The first motor is started to drive the output end to rotate, which drives the fan blade to rotate and blow air, accelerating the rapid circulation of cool air and improving the heat dissipation effect of the control box. The filter screen can filter dust in the air. When the first motor drives the output end to rotate, it can drive the first bevel gear to rotate. Due to the meshing relationship, the first bevel gear receives force to drive the second bevel gear to rotate, thereby driving the rotary shaft to rotate. Thus, the top plate drives the scraper blade to slide along the surface of the filter screen, cleaning the dust attached to the filter screen and avoiding clogging of the filter screen. After the scraper blade is worn and thinned after long-term use,The deformation of the elastic air bag can push the scraper blade into contact with the filter screen, ensuring the cleaning effect of the scraper blade.

[0009] Preferably, a second bevel gear is fixedly fitted to the outside of the rotating shaft, and the second bevel gear meshes with the first bevel gear, and due to this meshing relationship, when the first bevel gear receives a force and rotates, it can drive the second bevel gear to rotate.

A locking ball is glued in the elastic block, and the locking ball is slidably connected to the locking hole. The second motor drives the output shaft to rotate, thereby driving the second pulley to rotate, and then driving the belt to transmit power, and finally driving the first pulley to rotate. The first pulley is subjected to a force to drive the rotating end to rotate, thereby driving the sealing ball to bend, which causes the through hole opened in the sealing ball to rotate, and thus the oil storage cylinder to enter a flow state. In this process, the locking hole is subjected to a force to drive the locking ball The locking ball pushes out, and the locking ball is subjected to force and pushes the elastic block to deform, and finally the locking ball breaks away from the locking hole, and under the action of force, the locking ball slides along the surface of the output shaft of the second motor, and when the locking ball slides into the next locking hole, the elastic block restores its deformation and pushes the locking ball into the locking hole, restricting the output shaft of the second motor and thereby accurately controlling the rotation position of the sealing ball, and finally the lubricating oil flows into the hydraulic press through the guide tube, and the lubricating oil contacts the telescopic end of the hydraulic cylinder and lubricates the hydraulic cylinder.

[0013] Preferably, a plurality of the locking holes are provided, and the plurality of locking holes are arranged in an annular array on the output shaft of the second motor, and by providing the locking holes, it becomes easy to achieve a locking connection in combination with the locking hole ball.

[0014] The method of using the apparatus for producing natural fiber filling materials specifically includes: Step 1: preparing filaments from wood fiber, hemp fiber and polypropylene fiber, the mass ratio of wood fiber, hemp fiber and polypropylene fiber being (1-3):(3-5):(3-5), and weaving the obtained filamentous fibers into a mixed fiber felt by a mixed fiber felt making machine through opening, pre-mixing, mixing and separating, carding, crossing, wrapping, pre-needling, main needling and cutting, and then placing the mixed fiber felt into an open oil-heated mold and heating it in the open oil-heated mold at a temperature of 200-240°C for 1-2 minutes; Step 2: Take out the soft mixed fiber felt and put it into the lower mold. Apply 20-25Mpa pressure with a hydraulic press to keep the mixed fiber felt in the mold for 2-3 minutes, and then take out the molded natural fiber substrate. In this process, a control box is provided to control the use of the hydraulic cylinder, and to ensure that the electronic components in the control box can operate at normal temperatures. The semiconductor cooling sheet is then activated to cool the air. The first motor is then activated to drive the output end to rotate, thereby driving the fan blades to rotate and blow out air, accelerating the rapid circulation of cool air and improving the heat dissipation effect of the control box. The filter screen can filter the dust in the air. When the first motor drives the output end to rotate, it can drive the first bevel gear to rotate. Due to the meshing relationship, the first bevel gear is forced to rotate the second bevel gear, thereby driving the rotating shaft to rotate. This allows the top plate to drive the scraper blade to slide along the surface of the filter screen, cleaning the dust adhering to the filter screen and avoiding clogging of the filter screen. After the scraper blade is worn and thinned after long-term use, the elastic air bag can deform and press the scraper blade to contact the filter screen, ensuring the cleaning effect of the scraper blade. Step 3. The second motor is started to drive the output shaft to rotate, which drives the second pulley to rotate, and then drives the belt to transmit power. Finally, the first pulley is driven to rotate, and the first pulley is forced to rotate its rotating end, which drives the sealing ball to bend, causing the through hole in the sealing ball to rotate, and the oil storage cylinder to enter a fluid state. In this process, the locking hole is forced to push the locking ball out, and the locking ball is forced to press the elastic block to deform. Finally, the locking ball is released from the locking hole. Due to the force, the locking ball slides along the surface of the output shaft of the second motor. When the locking ball slides into the next locking hole, the elastic block restores its deformation and presses the locking ball into the locking hole, restricting the output shaft of the second motor and thereby accurately controlling the rotation position of the sealing ball. Step 4. The lubricating oil flows into the hydraulic press through the guide tube, and contacts the telescopic end of the hydraulic cylinder to lubricate the hydraulic cylinder. Next, the natural fiber substrate is placed back into the open oil-heated mold, the soft mixed fiber felt is removed and placed in the lower mold, a pressure of 315-500T is applied in the hydraulic press, the mixed fiber felt is held in the lower mold for 8-10 seconds, the molded natural fiber core material is removed, adhesive is applied to the two boards with a single-sided roller adhesive applicator for later use, the core material is placed between the two boards, and they are placed in a cold press for 1-2 minutes, and the molded natural fiber substrate is removed (step 5).

7. The method for using the device for producing a natural fiber filling material according to any one of claims 1 to 6 comprises, in particular: Step 1: preparing filaments from wood fiber, hemp fiber and polypropylene fiber, the mass ratio of wood fiber, hemp fiber and polypropylene fiber being (1-3):(3-5):(3-5), and weaving the obtained filamentous fibers into a mixed fiber felt by a mixed fiber felt making machine through opening, pre-mixing, mixing and separating, carding, crossing, wrapping, pre-needling, main needling and cutting, and then placing the mixed fiber felt into an open oil-heated mold and heating it in the open oil-heated mold at a temperature of 200-240°C for 1-2 minutes; Step 2: take out the soft mixed fiber felt and put it into the lower mold, apply a pressure of 20-25 MPa to the hydraulic press to keep the mixed fiber felt in the mold for 2-3 minutes, and then take out the molded natural fiber substrate; In this process, a control box is provided to control and use the hydraulic cylinder; the semiconductor cooling sheet is activated to cool the air, ensuring that the electronic components in the control box can operate at normal temperatures; the first motor is activated to drive the output end to rotate, which drives the fan blades to rotate and blow air, accelerating the rapid circulation of cool air and improving the heat dissipation effect on the control box; the filter screen can filter out dust in the air; and when the first motor drives the output end to rotate, it can drive and rotate the first bevel gear, which engages. According to the relationship, the first bevel gear receives a force to drive the second bevel gear (11921) to rotate, thereby driving the rotating shaft to rotate, so that the top plate drives the scraper blade to slide along the surface of the filter screen, cleaning the dust adhering to the filter screen and avoiding the clogging of the filter screen. After the scraper blade is worn and thinned due to long-term use, the deformation of the elastic air bag can push the scraper blade to contact the filter screen, ensuring the cleaning effect of the scraper blade. Step 3. Step 4: The second motor is started to drive the output shaft to rotate, which drives the second pulley to rotate, and then drives the belt to transmit power. Finally, the first pulley is driven to rotate. The first pulley is subjected to a force to drive the rotating end to rotate, which drives the sealing ball to bend. This causes the through hole in the sealing ball to rotate, and the oil storage cylinder enters a fluid state. In this process, the locking hole is subjected to a force to push the locking ball out, and the locking ball is subjected to a force to press the elastic block to deform. Finally, the locking ball is released from the locking hole. Due to the force, the locking ball slides along the surface of the output shaft of the second motor. When the locking ball slides into the next locking hole, the elastic block restores its deformation and presses the locking ball into the locking hole, restricting the output shaft of the second motor and thereby accurately controlling the rotation position of the sealing ball. Finally, the lubricating oil flows into the hydraulic press through the guide tube, and contacts the telescopic end of the hydraulic cylinder to lubricate the hydraulic cylinder. and (5) step 5: next, placing the natural fiber substrate back into the open oil-heated mold, removing the soft mixed fiber felt and placing it in the lower mold, applying a pressure of 315-500T in a hydraulic press to hold the mixed fiber felt in the lower mold for 8-10 seconds, removing the molded natural fiber core, applying adhesive to the two boards with a single-sided roller adhesive applicator for later use, placing the core between the two boards, placing them in a cold press to press for 1-2 minutes, and removing the molded natural fiber substrate.
