Cooling and shaping device for wood-plastic solid wood composite material

Abstract

The invention relates to the technical field of wood-plastic solid wood composite materials, in particular to a cooling and shaping device for a wood-plastic solid wood composite material. The cooling and shaping device comprises a cooling water tank and an upper mold, the left side and the right side of the lower surface of the cooling water tank are each provided with two supporting legs, and a splash-proof cover plate is arranged at the top of the cooling water tank. Connecting blocks are installed on the left side and the right side of the lower surface of the cooling water tank, a water storage tank is installed at the lower ends of the two connecting blocks, two heat discharging holes are formed in each of the left side and the right side of the upper surface of the water storage tank, a PLC is installed in the middle of the lower surface of the cooling water tank, and a water-cooling heat dissipation device is installed in the middle of the lower surface of the water storage tank. According to the cooling and shaping device, the water cooling efficiency of the wood-plastic composite material is improved through mutual cooperation of the structures, the water consumption of the cooling device is reduced through circulating cooling of water, it is guaranteed that the product is qualified, certain cooling is completed through the split type shaping mold during product shaping, and wood plastic is prevented from deforming before entering the cooling water tank.

Description

technical field [0001] The invention relates to the technical field of wood-plastic solid wood composite materials, in particular to a cooling and shaping device for wood-plastic solid wood composite materials. Background technique [0002] Wood-plastic composite material is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride instead of the usual resin adhesive, and more than 50% of wood powder, rice husk, straw, etc. Waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques. Wood-plastic composite materials have some characteristics of plastic and wood, which makes wood-plastic composite materials have good processing performance and strength performance. , which is water-resistant, corrosion-resistant, and has a long service life. The plates or profiles produced are ...

AI Technical Summary

Problems solved by technology

[0003] During the processing of existing wood-plastic composite materials, it needs to be shaped and cooled after co-extrusion. The current cooling method generally adopts water cooling. The existing cooling method generally directly erects the water outlet pipe above the wood-plastic composite material, directly It is used for cooling, and its cooling efficiency is high, but the waste of water resources in this water-cooling process is serious, and the cooled water is also collected to continue cooling work, but its water-cooling efficiency is low, which may easily lead to incomplete cooling of wood-plastic and reduce the quality of finished products , and the existing sizing dies are generally directly connected with the co-extrusion device and are designed in one piece. The maintenance and inspection of the one-piece sizing die is inconvenient, and the heat dissipation efficiency of the existing sizing device is low, which may easily cause the wood-plastic composite material to be sent out without entering When cooling the water tank, the wood-plastic composite material is unqualified due to deformation due to external force or other factors
