Natural fiber composites are composite materials formed by combining natural fibers as reinforcements with a polymer matrix. The core of processing natural fibers and substrates into composite materials is to achieve an effective combination of the two through physical, chemical or biological means.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. A multi-pressure mixing component is provided. The internal pressure adjustment mold is driven by the pressure hydraulic cylinder to change the internal space size of the lower pressure top mold and the rising bottom mold. The base material is injected into the liquid inlet processing chamber by the liquid inlet operation pipe, the liquid storage fixed box and the injection pump. The opening and closing electric push rod drives the opening and closing processing block to open and close the liquid inlet fixed pipe, and the base material is injected into the side end of the fiber material. The lower pressure top mold is driven by the lower pressure hydraulic cylinder and the rising bottom mold is driven by the rising hydraulic cylinder to move in opposite directions. The internal pressure adjustment mold is heated by the fixed electric heater, and the base material and the fiber material are hot-pressed to realize the hot pressing molding of the composite material. The lifting electric slide rail drives the lifting positioning plate to slide along the lower pressure top mold and the rising bottom mold, and the two ends of the lower pressure top mold and the rising bottom mold are limited to realize steady positioning support, so that when the composite material is formed, the side end can be limited, thereby realizing continuous production processing, and through thickness adjustment and continuous pressing, the continuous production processing of composite materials of different thicknesses can be realized, reducing the waiting time required for equipment adjustment and improving production efficiency;

[0043] The fiber material is soaked by entering and exiting the soaking box, and the fiber material is guided by the guide limit column. The two sets of piezoelectric slide rails drive the pressure treatment column to push the fiber material to swing left and right, and the fiber material is limited and flattened. The limit electric slide rail drives the limit sliding plate, the limit motor and the two-way screw drive the limit clamping plate to limit the side end of the fiber material to avoid bending, folding and stretching fracture when swinging left and right. The fiber material and the base material are hot-pressed to form with the pressure hydraulic cylinder, the correction treatment mold and the hot pressing fixture to achieve preliminary shaping of the material, so that the material can be pre-shaped during production to avoid stretching fracture or bending and folding caused by deformation of the material, and ensure the stability of continuous production of the material;

[0044] By adjusting the hot pressing space and coordinating the feeding processing with the limiters at both ends and the continuous feeding components, continuous production of materials of different thicknesses can be achieved. The fiber material is pushed to move by the limiters on both sides and the left and right swings, and the flatness and tensile strength of the fiber material are adjusted. This effectively solves the problem in the prior art that the internal dimensions of the mold cannot be adjusted, resulting in the thickness cannot be quickly adjusted during material production, affecting the speed of continuous material production. The feed and discharge positions can be adjusted and changed in real time, and the material shape can be modified to avoid breakage or folding, thereby improving the production speed and quality of the product.

[0045] 2. An in-and-out pressure limit component is provided. The load-bearing support rod with the fiber raw material is inserted into the inner side of the integrated limit frame, and the load-bearing support rod is fixed by magnetic attraction with the reciprocating electromagnetic sleeve. The processing electric push rod drives the processing operation frame to rise and fall, and the fiber material is squeezed and limited by the guide matching roller. The mobile electric slide rail drives the mobile clamping plate to limit the side end of the fiber material. The pressure electric push rod drives the double convex limit rod to move downward. The double convex limit rod and the guide matching roller are clamped together, and the reciprocating electromagnetic sleeve and the load-bearing support rod are driven to rotate with the pressure motor to retract and release the material, so as to ensure the overall flatness and compactness of the fiber material during discharging, and correct the discharging position to avoid unilateral tensile fracture and ensure the stability of continuous discharging.

[0046] The collecting electric push rod drives the supporting outer discharge box to move downward, the vacuum pump and the adsorption tube rack perform vacuum adsorption on the connection position with the composite material, and cooperate with the shaping condenser to cool and shape the composite material. The outer discharge electric slide rail drives the outer discharge limit frame and the collecting electric push rod to move, and the adsorption tube rack is used to adsorb the composite material, so that the material can be effectively limited when discharged to ensure the flatness of the output material. The flatness of the material input and output is achieved through the restriction of input and output, avoiding the bending, folding or separation and breakage of the material, and improving the stability of the input and output.

[0047] In summary, through the cooperation of the multi-pressure mixing component and the inlet and outlet pressure limiting component, the inlet and outlet material pushing and limiting and the cooling reciprocating in and out are utilized to drive the continuous movement of raw materials and finished products, and the internal pressing and limiting are coordinated to limit the materials. Through multi-stage hot pressing and size adjustment, the production can be fast and continuous during the production and molding of materials, thereby improving the production speed and product quality of the products.

[0089] The working principle and use process of the present invention are as follows: when producing natural fiber composite materials, the staff inserts the natural fiber coil raw material into the inner side of the load-bearing support rod 304, inserts the load-bearing support rod 304 into the inner side of the integrated limiting frame 301, and inserts the load-bearing support rod 304 into the inner side of the reciprocating electromagnetic sleeve 303. The staff pulls the natural fiber material along the integrated limiting frame 301 to penetrate into the side end of the guide matching roller 308, and penetrates the natural fiber material into the inner side of the in-and-out soaking box 219 to achieve steady feeding processing. During the feeding process, the mobile electric slide rail 312 drives the mobile clamping plate 313 to push the natural fiber coil to move and align along the load-bearing support rod 304, so as to limit the fiber material and ensure the stability of its feeding alignment.

[0090] When the natural fiber material enters the in-and-out soaking box 219, the natural fiber material is soaked by the soaking substrate in the in-and-out soaking box 219, and the natural fiber material is guided by multiple sets of guide limit columns 220. The piezoelectric slide rails 221 drive the pressure treatment columns 222 to move in opposite directions, and the pressure treatment columns 222 are used to squeeze the soaked natural fiber material so that the natural fiber material can be flattened during soaking, and the moving path is changed at the same time. Through continuous pressing and left and right pulling, the natural fiber material is flattened. The two-way screw rod 226 is driven by the limit motor 225 to rotate, and the two-way screw rod 226 drives the limit clamping plate 227 to move along the inlet and outlet soaking box 219, thereby limiting the side end of the natural fiber material to avoid the side end deviation and the situation of folding on one side and stretching on the other side, which not only avoids the breakage of the fiber due to pulling, but also ensures the uniformity of fiber soaking;

[0091] When the fiber moves out from the impregnation position, the fixed-pressure electric slide rail 223 drives the fixed-pressure limiting column 224 to cooperate with the guide limiting column 220 to press the fiber and the mixed substrate to limit the thickness of the substrate to avoid the situation where the thickness is too thick due to the large amount of substrate carried on its surface during impregnation and discharging. The composite material after preliminary pressing and shaping moves to the inner side of the separation operation frame 228, and the two sets of opposing pressure hydraulic cylinders 232 drive the correction processing mold 233 and the hot pressing fixture 234 to move in opposite directions to extrude the composite material. During the extrusion process, the hot pressing fixture 234 is used to heat the correction processing mold 233, thereby heating the composite material. During hot pressing molding, the hot steam in the separation operation frame 228 is discharged through the exhaust fan 236 and the exhaust fixing pipe 235 to achieve rapid internal cooling and ensure the stability of the internal environment.

[0092] The composite material after hot pressing is moved along the separation limiting roller 229 to the inner side of the processing integration frame 1. When feeding, the limiting electric slide rail 230 drives the limiting sliding plate 231 to move along the separation operation frame 228 to limit the feeding of the composite material, ensure the stability of the feeding alignment, and place the composite material between the lower pressing top mold 202 and the rising bottom mold 204. The internal pressure adjustment mold 206 is driven by the pressure hydraulic cylinder 205 to move along the lower pressing top mold 202 and the rising bottom mold 204 to adjust the space inside the lower pressing top mold 202 and the rising bottom mold 204, so that the internal size can be adjusted according to the required size during pressing. The lifting electric slide rail 208 drives the lifting positioning plate 209 to move along the lower pressing top mold 202 and the rising bottom mold 204, and the position of the lifting positioning plate 209 is adjusted according to the size required for production, so as to ensure that the position of the equipment processing can be adjusted when producing composite materials of different thicknesses, so that the equipment can be used for the production of composite materials of different thicknesses, thereby expanding the production range of the equipment;

[0093] The substrate in the liquid storage fixed box 215 is extracted by the liquid injection pump 216 and the liquid inlet operation pipe 214, and the substrate enters the inner side of the liquid inlet processing chamber 210 along the liquid inlet operation pipe 214. At this time, the opening and closing electric push rod 212 drives the opening and closing processing block 213 to move along the liquid inlet fixed pipe 211, opens the liquid inlet fixed pipe 211, and discharges the substrate into the inner side of the rising bottom mold 204 along the liquid inlet processing chamber 210 and the liquid inlet fixed pipe 211. The lower pressure top mold 202 is driven downward by the lower pressure hydraulic cylinder 201, and the rising hydraulic cylinder 203 drives the rising bottom mold 204 to rise. The lower pressure top mold 202 and the rising bottom mold 204 are used to fit together to extrude the substrate and the composite material, and the fixed electric heater 207 is used to perform hot pressing and curing molding on the substrate and the composite material. During the liquid inlet process, the stirring motor 217 drives the stirring operation frame 218 to stir the substrate in the liquid storage fixed box 215 to achieve substrate mixing treatment and ensure the uniformity of the substrate.

[0094] The composite material after hot pressing is moved to the inner side of the outer limiting frame 315, and the collecting electric push rod 316 drives the supporting outer box 317 to move downward, and the vacuum pump 318 and the adsorption tube rack 319 perform vacuum adsorption on the connection position with the composite material, and cooperate with the shaping condenser 320 to cool and shape the composite material, and the outer electric slide rail 314 drives the outer limiting frame 315 and the collecting electric push rod 316 to move, and the adsorption tube rack 319 is used to adsorb the composite material, so that the material can be effectively limited when it is discharged, and the flatness of the discharged material is ensured. In the process of production and feeding, the processing electric push rod The rod 306 drives the processing operation frame 307 to rise and fall, and the fiber material is squeezed and restricted by the guide matching roller 308. The movable electric slide rail 312 drives the movable clamping plate 313 to limit the side end of the fiber material. The pressure electric push rod 309 drives the downward pressure linkage frame 310 and the double convex limiting rod 311 to move downward. The double convex limiting rod 311 and the guide matching roller 308 are clamped together, and the pressure motor 302 drives the reciprocating electromagnetic sleeve 303 and the load-bearing support rod 304 to rotate, so as to retract and release the material, realize the compactness of the fiber material, realize the steady restriction of the fiber material, and improve the accuracy of the feeding positioning.
