Problems solved by technology
However, as mentioned above, because the calibrator 4 must be positioned adjacent to the die, there are limitations on the diameter and circumferential length of the embossing rolls disposed therebetween.
Therefore, the repetition period of the pattern repeatedly formed on the surface of the profile becomes short and thus its patternability is deteriorated

Embodiment Construction
[0034] Hereinafter, embodiments of the present invention will be described in detail.
[0035] figure 2 It is a schematic diagram of an apparatus for manufacturing window frame profiles according to an embodiment of the present invention. reference figure 2 If pellets or composite materials of thermoplastic resin such as polystyrene (PS), polyethylene (PE), polypropylene (PS), polyvinyl chloride (PVC) and ABS resin are injected into the main extruder 10 through the hopper 2 , The material is heated by a heater arranged in the main extruder 10 so as to be melted into a gel state and conveyed by the rotation of the extrusion screw. Thereafter, the profile P having the desired shape is extruded by the die 30 arranged on the front side of the main extruder 10, passes through the aligners 70, 80 and the cooling device 90, and then passes through the pulling device 99 and the cutting machine, pulling device The 99 and cutting machine are similar to the prior art and therefore detail...

An auxiliary coextrusion apparatus (100) for window frame profiles is disclosed. In the auxiliary co-extrusion equipment (100) for window frame profiles, the co-extrusion resin composition is pressurized and delivered to one side of the die (30) so that the resin material used to form the profile (P) The skin layer (S) is formed on the surface of the profile (P) when melted in the main extruder (10) and then pressurized and conveyed to the die, said auxiliary co-extrusion equipment is characterized in that it includes A connector (10) that straightly changes the direction of travel of the co-extruded resin composition, curved portions (113, 114) that smoothly changes the direction of travel of the resin composition are formed in the inlet hole (111) and the outlet hole ( 112) between. The present invention provides improved access to auxiliary co-extrusion equipment in order to prevent carbonization of the resin composition therein and also prevent excessive energy consumption while conveying the resin composition, enabling enhanced patterning of patterns formed on profile skin layers.
Description
Technical field [0001] The present invention relates to a device for manufacturing window frame profiles with natural wood texture using co-extrusion technology, and in particular to the shape of an auxiliary co-extrusion device used for two-stage extrusion. The auxiliary co-extrusion device is set In the equipment for manufacturing window frame profiles, a resin composition containing wood fibers is double-staged on one side thereof and embossed thereon, thereby providing a pattern with natural wood texture. Background technique [0002] In the extrusion process of manufacturing conventional window frame profiles, such as figure 1 As shown, if pellets of thermoplastic resin or composite materials are injected into the extruder 1 through the hopper 2, the material is heated by a heater arranged in the heating cylinder of the extruder 1 to melt into a gel state, and the The rotation of the screw is conveyed and then extruded through a die 3 arranged at the front end of the extrude...
