The water cooling machine 64 is started, the water cooling machine 64 drives water cooling liquid in the return wave return pipe 62 to flow back and cool and shape the extruded wood-plastic plate moving to the discharge end of the covering die body 2, so that the problem that the wood-plastic plate is bent due to micro deformation in the discharge process of the discharge end of the covering die body 2 is avoided, and the quality of the wood-plastic plate is improved.
In the process that water-cooling liquid circulates in the return wave return pipe 62, when the water-cooling liquid flows through the diversion round pipe 63, the water-cooling liquid drives the inner ring impeller 81 to rotate through the blades of the inner ring impeller 81, the inner ring impeller 81 drives the lug on the inner ring impeller to rotate, the lug of the inner ring impeller 81 pushes one end of the L-shaped push plate 82 to move, the other end of the L-shaped push plate 82 pushes the return sleeve plate 84 to move towards the discharge end of the covering die body 2, the inclined surface of the return sleeve plate 84 pushes one end of the U-shaped rod 85 to move upwards, the other end of the U-shaped rod 85 drives one side of the elastic sheet 86 to tilt, so that the elastic sheet 86 forms a round edge and is far away from the wood-plastic plate, the separation efficiency of the wood-plastic plate and the covering die body 2 is promoted, and meanwhile, the round edge formed by the elastic sheet 86 protects the edge of the covering die body 2, so that the problem that the wood-plastic plate is damaged due to friction at the discharge end port of the covering die body 2 when the wood-plastic plate deviates is avoided.
When the electric heating rotating rod 51 rotates, the electric heating rotating rod 51 drives the lug on the electric heating rotating rod 51 to rotate, the lug of the electric heating rotating rod 51 pushes the L-shaped rod 73 to move in the direction away from the material covering module body 2, the L-shaped rod 73 drives the sliding column 72 to move along the sliding groove of the triangular arc plate 71, the sliding column 72 pushes the triangular arc plate 71 to move towards the center of the module body 1, the triangular arc plate 71 extrudes and moves towards the center of wood plastic materials in the module body 1, and therefore the problems that insufficient feeding occurs in the middle part of the wood plastic plate, hollowness occurs, and dishing occurs on the surface of a product are avoided, and therefore the quality of the wood plastic plate is ensured.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
