Abstract
The invention relates to a method for manufacturing a wood-plastic pattern section, in particular to a production technology for directly extruding various curve patterns during extrusion molding of a polyvinyl chloride (PVC) and wood powder composite material, a poly ethylene (PE) and wood powder composite material, a propene polymer (PP) and wood powder composite material and other composite materials. The method comprises the following steps of: 1, arranging a special base extrusion die head in a required shape on the original wood-plastic extruding machine; 2, replacing the original stock mould by using a pattern molding device which is designed and manufactured according to the method; and 3, normally producing by using the original stock cooling platform and drawing and cropping equipment. The method is widely applied to development of wood-plastic products; and by the method, the application processes of wood-plastic composite materials in all fields are accelerated, and great social and economic benefits can be generated.
Description
Technical field
The present invention relates to a kind of manufacturing approach of Wood-plastic profiles, specifically in composite forest material extrusion moldings such as PVC/ wood powder, PE/ wood powder, PP/ wood powder, directly extrude a kind of production technology of various curve floral designs.
Background technology
This novel wooden basic ring of wood plastic composite is protected material at present, and being to use the field still is that quality level has all had development by leaps and bounds and raising.Wood plastic composite is also replaced log to be used in many-sides such as house decoraton, garden architecture, household apparatus by everybody understanding step by step more and more extensively.But production technology and equipment that developing wood plastic composite all adopts the mould shape linearity to extrude in process of production, the linear section bar that the section bar of being produced can only be extruded through shaper has restricted wood plastic composite in the puzzled application of each neck.
The section bar that the domestic and international at present application to said material all is confined to an extrusion molding is with the linear material of extruding and lead stretches; If go out the intricate detail patterned surfaces in the section bar Surface Machining; To its adopt conventional method like: car, mill, engrave, bore, carve, quarter etc.; These means are processed complex not only, and technical difficulty is big, mechanical strength and surperficial texture that also can the heavy damage product.More have because of wood plastic composite mostly adopts hollow core structures to process to be suitable for section bar with the advantage that embodies its cost performance, so be difficult to process by existing method.
Summary of the invention
In order to overcome the deficiency of present technology, the present invention provides and processes various concavo-convex, decorative patterns, curve, the technology section bar of pattern such as line crosswise, as: photo frame, cabinet limit, cross band, drawing-board etc., expanded the range of application and the field of moulding wooden composite forest material greatly.Be convenient to promote and use.
Technical solution of the present invention has the following steps:
A, mould the extrusion die at the bottom of loading onto photo frame, cabinet limit, cross band or drawing-board shape bases on the extruder at original wood; Carry out 120 ~ 250 ℃ of high temperature extrusion moldings of composite processes such as PVC/ wood powder, PE/ wood powder, PP/ wood powder then, obtain the wood plastic composite section bar at the extrusion die place;
The wood plastic composite section bar that B, A step obtain; Under 120 ~ 250 ℃ of temperature; Entering is provided with the pattern calibrator of upper and lower mould and finalizes the design; The patrix of said calibrator is the synchronous rolling embossed wheel of linear speed (the pattern forming device replaces former stock mould), and said pattern calibrator is that wood is moulded embossing machine or embossing machine;
C, B step come out to obtain, and continue to use former typing cooling bench and traction, blank equipment gets final product ordinary production.
Above-mentioned three steps can be sketched and are:
The first step: mould the required shape substrate extrusion die of loading onto special use on the extruder at original wood;
Second step: the pattern forming device that designs and produces with the present invention replaces former stock mould;
The 3rd step: continue to use former typing cooling bench and traction, blank equipment gets final product ordinary production.
The present invention is producing surperficial texture and the strength problem that this type solved converted products; Have again simultaneously that equipment requirements is not high, production simple and the stock utilization advantages of higher; Can be widely used in the Application and Development of wood-plastic products; Accelerate the application process of wood and plastic composite, can produce huge social effect and economic benefit in each field.

The specific embodiment
Embodiment 1
The present invention has the following steps:
A, mould the extrusion die at the bottom of loading onto the photo frame shape bases on the extruder, carry out 120 ℃ of high temperature extrusion moldings of PVC/ wood flour composite material process then, obtain the wood plastic composite section bar at the extrusion die place at original wood;
The wood plastic composite section bar that B, A step obtain; Under 250 ℃ of temperature; Entering is provided with the pattern calibrator of upper and lower mould and finalizes the design; The patrix of said calibrator is the synchronous rolling embossed wheel of linear speed (the pattern forming device replaces former stock mould), and said pattern calibrator is an embossing machine;
C, B step come out to obtain, and continue to use existing typing cooling bench and traction, blank equipment gets final product ordinary production.
It is existing that to adopt the certificate of processing of the present invention that the phase frame section of intricate detail pattern is arranged with us be example; We mould at original wood and transform and install special-purpose extrusion die of the present invention and the disposable frame section mutually with intricate detail pattern of producing of special-purpose pattern shaped device on the extruding production line, embody its technological advantage well.The photo frame shape technique lines of being produced are abundant lively, have the effect of solid wood fully, and have the advantage that solid wood does not have,, anticorrosion little like: waterproof, mildew-resistant, insect protected, distortion etc.This product has just tied development work at present, and oneself receives many professional quarters and the good evaluation of applying unit.
