Abstract
The invention discloses a PVC wood-plastic surface hardened composite co-extruder head. The PVC wood-plastic surface hardened composite co-extruder head comprises a co-extruder head body. A first die is arranged at the end of the co-extruder head body. A second die is arranged at the bottom of the first die. A third die is arranged at the bottom of the second die. A transition plate is arranged at the bottom of a support plate. A die body is arranged at the bottom of the transition plate. A feeding inlet is formed in one side of the third die. A heat insulated tank is arranged inside the first die. A co-extrusion flow channel is formed in the other side of the second die. According to the PVC wood-plastic foaming co-extruder head provided by the invention, a co-extrusion layer and a wood-plastic base material can be integrated, and disengaging and fading cannot happen easily. The gradually-changed co-extrusion flow channel is adopted, pressure can be balanced, even feeding is achieved, and the material overflowing phenomenon between die plates is avoided. Moreover, the thickness of the co-extrusion layer is 0.3mm and is uniform, and bright lines are avoided. Meanwhile, a cooling water channel is formed in the upper side of the first die, the heat insulated tank is formed at the lower side of the first die, products can be cooled and formed quickly before demolding, and thus the surface hardness is high.
