Description
Technical field
The present invention relates to a kind of cross-head, especially relate to a kind of wood and mould corrugation core moulding extruder head.
Background technology
Corrugated board is used widely in packaging industry because of pollution-free, renewable, good advantages such as shock-absorbing capacity.So far, corrugated board has become one of most popular packaging material in the modern packaging industry, and the corrugated case output value accounts for more than 30% of the packaging industry goods gross output value.But through the nearly 150 years effort practice of world wide class, the corrugated board technology deepens constantly.The development of corrugated board has now reached the limit, and the corrugated case supply and demand is seriously superfluous, and corrugated case industry is being ahead of the speed of economic development always.With regard to China, equipment too much, dog-eat-dog, situation such as benefit is low, technical threshold is low etc., and reason has caused corrugated case to be in serious surplus for a long time, and product structure is single.Reality that it must be admitted that, the corrugation technology enters the senescence phase through the development of a century and a half, must inject new vitality.
Wood plastic composite (being called for short WPC) is because of its reusable edible, little, the excellent comprehensive performance of environmental pollution, especially can be outstanding advantages such as basic production raw material with biomass resources such as wood machining residues and waste or used plastics, the eighties in last century just oneself through beginning on the floor, aspects such as liner, decoration, furniture, firm splint material are applied, the WPC Development of Materials is acceleration tendency over nearly 30 years.The advantage of Wood-plastic foam composite mainly be have heat insulation, sound insulation, buffering, mechanical strength height, strong acid-base resistance corrosivity strong, utilize agriculture and forestry organic waste material such as wood powder, economic environmental protection.
At present, also do not have a kind of equipment a direct step to extrude wood both at home and abroad and mould corrugated section bar.Wood plastic composite is made stupefied technology by extruding, apply to the corrugated board field, have huge market prospects.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the invention provides a kind of simple in structurely, the wood of high efficiency is moulded corrugation core moulding extruder head.
Technical scheme of the present invention is: it comprises a pair of upper die body and the lower mold body that fastens up and down, described upper die body links to each other with extruder by the mould neck with lower mold body, be provided with the arm runner between upper die body and lower mold body, mould neck center is provided with through hole, and mould neck central through hole communicates with the arm runner, it is characterized in that, at upper die body end and lower mold body end the corrugation roller is installed all, be with bearing on the axle of described corrugation roller, corrugation roll shaft end is provided with drive, and the corrugation roller links to each other with motor by drive.
Described mould neck and extruder junction are provided with porous plate, are beneficial to make batch mixing more even.
The described upper die body left and right sides and the lower mold body left and right sides have been equipped with the end briquetting of strengthening fixation.
Described corrugation roller two ends are equipped with sleeve.
The described corrugation roll shaft outside is provided with end cap.
Described corrugation roll shaft end is provided with water inlet pipe and outlet pipe, corrugation roller center is provided with cooling water chamber, water inlet pipe and outlet pipe all communicate with cooling water chamber, and the cooling water chamber diameter is 0.3 ~ 0.6 times of corrugation roller diameter, and the diameter of water inlet pipe and outlet pipe is 0.1 ~ 0.2 times of corrugation roller diameter.
Described arm runner is streamlined, and leading portion is a breeze way, and back segment is a smooth section.
The described corrugation roller of being located at the upper die body end is symmetrically distributed in arm runner smooth section both sides with the corrugation roller of being located at the lower mold body end, and two corrugation roller roller teeth do not contact all the time.
All be fixed with heating collar on described upper die body upper side and the lower mold body downside, described heating collar end terminates in arm runner breeze way and smooth section is joined at the interface.
Distance between the center line of the axle of described corrugation roller and the die orifice that is formed by upper die body end and lower mold body end gap is 0.8 ~ 1.5 times of corrugation roller diameter.
The quantity of the roller tooth of described corrugation roller, size and and shape (as V-type) all can regulate.
Operation principle: mould melt from the wood that extruder is extruded, flow into the arm runner through the mould neck, described arm runner is streamlined, help guaranteeing that wood moulds the smooth circulation of melt, the breeze way that wood is moulded melt process arm runner flows to smooth section, the upper die body front end corrugation roller of flowing through subsequently, lower mold body front end corrugation roller.Because corrugation roller roller tooth is connected with motor by delivery wheel, driven by motor corrugation roller rotates with certain speed.Cooling water enters into cooling water chamber from water inlet pipe, flow out from outlet pipe again, because the existence of cooling water chamber, the corrugation roll temperature is well below melt temperature, upper die body front end corrugation roller roller tooth, lower mold body front end corrugation roller roller tooth do not contact all the time, and moulding the melt moulding that is cooled through the wood of two corrugation rollers is corrugation core shape.Then, pull out through the die orifice traction.Change quantity and the size and the shape of corrugation roller top roll tooth, can obtain the corrugation core shape of different size.
The present invention is simple in structure, high efficiency, and good product quality, applied range, the wood that mainly applies to polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) is moulded the manufacturing of corrugation core.
