Abstract

The invention belongs to the technical field of sectional material production and provides a wood-plastic co-extrusion sectional material production line and a wood-plastic co-extrusion sectional material production technology. The wood-plastic co-extrusion sectional material production line comprises a core body conveying device, a co-extrusion die and a water cooling groove which are sequentially arranged. The co-extrusion die is connected with a plastic feeding device. The co-extrusion die comprises an end portion die and a cavity die which are sequentially arranged. An extrusion cavity used for covering a core body with plastic is formed in the cavity die, and a feeding port used for the core body to pass is formed in the end portion die. The feeding port communicates with a feeding cavity stretching into the extrusion cavity, the extrusion cavity communicates with a gap, and the gap is connected with the plastic feeding device through a channel. By means of the wood-plastic co-extrusion sectional material production line and the wood-plastic co-extrusion sectional material production technology, the problem that the surface of a plastic layer of a wood-plastic sectional material is rough during production in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of profile production, and relates to a production line of wood-plastic co-extruded profiles and a production process thereof. Background technique [0002] Wood-plastic profiles are mainly made of wood as the base material, thermoplastic polymer materials (plastics) and additives. The thermoplastic polymer materials are mixed evenly and then coated on the surface of the profile by mold equipment and then extruded. High-tech wood-plastic profile, which has both the performance and characteristics of wood and plastic, is a new type of composite material that can replace wood and plastic. [0003] During the use of the current mold, the thermoplastic polymer material will have the problem of uneven flow after it is passed into the mold cavity, resulting in a rough surface formed by the thermoplastic polymer material on the wood, and the poor water cooling effect will lead to deformation of the formed surface ...
