[Technical field]

[0001] The present invention is in the field of board technology, and in particular 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 sheets, but also include wood planks, furniture planks, architectural 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, the existing apparatus for producing natural fiber filled materials still has certain defects when used. First, the existing apparatus for producing natural fiber filled materials often simply uses natural ventilation to dissipate heat in the control box on the hydraulic press, but the heat dissipation effect of natural ventilation is low, which causes the problem of low heat dissipation efficiency of the control box.

[0004] Next, existing equipment for producing natural fiber filling materials often uses a hydraulic press to press-mold mixed fiber felt, which has the problem that the hydraulic cylinder has large expansion and contraction resistance after long-term use due to the influence of material friction between the cylinder and the expansion and contraction rod.

8. The method of using the device for producing a natural fibre filling material according to any one of claims 1 to 7 comprises in particular Step 1: making wood fiber, hemp fiber and polypropylene fiber into filaments, in which the mass ratio of wood fiber, hemp fiber and polypropylene fiber is (1-3):(3-5):(3-5), and weaving the obtained filamentary 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 putting the mixed fiber felt into an open type oil heating mold and heating it in the open type oil heating 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 in a hydraulic press to keep the mixed fiber felt in the mold for 2-3 minutes, and take out the molded natural fiber substrate; In this process, by providing a control box, the hydraulic cylinder can be controlled and used; in order to ensure that the electronic elements in the control box can operate at normal temperature, the semiconductor cooling sheet can be started to cool the air; the first motor is started to drive the output end to rotate, thereby driving the fan blades to rotate and blow air to accelerate the rapid circulation of cool air, thereby improving the heat dissipation effect on 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, and the meshing According to the relationship, the first bevel gear receives the 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, clean the dust attached to the filter screen, avoid the clogging problem of the filter screen, and after the scraper blade is worn and thinned due to long-term use, the elastic air bag can deform to push the scraper blade to contact the filter screen, so as to ensure the cleaning effect of the scraper blade; Step 3; Step 4: start the second motor to drive the output shaft to rotate, thereby driving the second pulley to rotate, and then driving the belt to transmit power; finally, drive the first pulley to rotate, and the first pulley drives the rotating end to rotate under the force, thereby driving the sealing ball to bend, so that the through hole opened in the sealing ball rotates, and the oil storage cylinder enters a flow state; in this process, the locking hole is forced to push out the locking ball, and the locking ball is forced to push the elastic block to be deformed; finally, the locking ball is released from the locking hole; under the action of 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 to push the locking ball into the locking hole, and limits the output shaft of the second motor, thereby accurately controlling the rotation position of the sealing ball; 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 to lubricate the hydraulic cylinder; and (5) step 5: placing the natural fiber substrate back into the open oil heated mold, taking out the soft mixed fiber felt and putting it into the lower mold, applying a pressure of 315-500T in the hydraulic press to hold the mixed fiber felt in the lower mold for 8-10 seconds, taking out 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, putting it into the cold press to press for 1-2 minutes, and taking out the molded natural fiber substrate.
