Description

Wood plastic boards mold pressing process units

Technical field

The utility model relates to a kind of Wood plastic boards mold pressing process units.

Background technology

Wood materials and steel, cement, plastics also are called four big basic raw materials, and wood materials is unique can regeneration.China's big footpath level timber recoverable amount seldom at present; do not satisfy the demand in market, in order to solve this crisis, people advocate with steel on the one hand for wood, to mould Dai Mu; consume non-renewable oil and ore deposit iron resource again, caused the generation of one and another raw material crisis.On the other hand, few in the face of big tree, people glue together use to the small wood small powder with compound way, just must use a large amount of sizing materials for this reason, wherein are urea-formaldehyde glue more than 90%, and this is the main source that formaldehyde pollutes in the air.

About 1.3 hundred million tons of the output of present annual plastics in the world, China's output is above 2,000 ten thousand tons.The annual waste or used plastics that produces of China has accounted for the 1/3-1/4 of rubbish, owing to lack mature technique, the white pollution that causes has become a thorny problem of Chinese environmental protection cause.China has the string of several hundred million tons of photosynthesis generations to can not find the way of utilization every year now, burning year after year, discarded, people are thirsting for it is used, and produce that a kind of new material substitutes oil and timber uses, and wood is moulded and has been studied out under this background just.

External at home, it is extrusion molding than product faster that wood is moulded development, extruded quantitative limitation, the product overwhelming majority is long-pending plate and a bar of leptoprosopy, and the equipment of usefulness is single screw rod and double screw extruder, and product is used for leptoprosopy such as sash, floor, finishing material, rectangular material more, product has following defective: wood is moulded the extrusion molding difficulty, equipment, mould, subsidiary engine cost an arm and a leg, the precision prescribed height, and the product area is little, percent defective is high.

The utility model content

The purpose of this utility model provides a kind of Wood plastic boards mold pressing process units, and simple in structure, cost is low, the precision height.

For achieving the above object, technical scheme provided by the utility model is: a kind of Wood plastic boards mold pressing process units, include hot-air drier, lower bolster, spreading machine, laying fiber machine, upper padding plate, middle framed, loader, hot press, push-and-pull trigger, cold press, unloader, pressing mold, the conveyer of mating formation, bead cutter and sander; Described lower bolster, spreading machine, middle framed, lay the fiber machine and upper padding plate all is located on the conveyer of mating formation successively; Described hot-air drier is located at the front end of the conveyer of mating formation, and described loader, hot press, push-and-pull trigger, cold press, unloader, pressing mold, bead cutter and sander all are positioned at the rear end of the conveyer of mating formation successively.

Pressing plate on described hot press and the cold press is made as 8～16 layers of hollow pressing plate.

What feed in the pressing plate on the described cold press is cold water.

The blanking roller of mating formation of described spreading machine is made as the rectangular sealed material roller of gear-like.

Described spreading machine is provided with 2-3.

The wood that adopts must carry out the drying processing before moulding particle processing, wood after the processing is moulded the particle water content and is lower than 1%, affiliated drying is treated to heated-air drying, drier is common hot-air drier, dried particle enters spreading machine, described spreading machine is that wood is moulded the special-purpose spreading machine of particle, it is characterized in that: complete with the common wood-based plate spreading machine of structure such as its feed bin of spreading machine, transmission device, doffer is the same, and just the blanking roller of mating formation with spreading machine is gear-like, rectangular sealed material roller by cylinder, starlike distribution design.Article one, the spreading machine of streamline design number is 2～3, adds 1～2 layer of glass fibre or its cloth products in pavement process, carries out reinforcement.Spreading machine is moulded particle with wood and is layered in the mould that is moved by the transporter of mating formation, the described transporter of mating formation be design spreading machine under the dress trigger, continuous conveying device circular flow, that have chain to drive.Its operation principle is same as pallet conveyer.Described mould be is characterized in that by upper padding plate, lower bolster and middle framed the composition: upper padding plate, lower bolster are common cold-reduced sheet, middle framed common No. 45 steel square or circular model welding, thickness 5～30mm width 50～300mm that is.Earlier with upper padding plate, lower bolster and middle framed spray oil or oil emulsion, also can lay barrier paper before mating formation, in order to the demoulding, described oil or oil emulsion are silicone oil, conduction oil and emulsification product, and barrier paper is a common paper.The assembling die that assembles is moved into hot press by the dress trigger carry out the hot pressing slaking, thermal pressure is 15-25mpa, and temperature 180-250 degree has the push-and-pull trigger that assembling die is pulled out by hot press after the slaking, and then the cold press that pushes that links up cools off.Described hot press, push-and-pull trigger, unload hot press, push-and-pull trigger that trigger is common wood-based plate, unload trigger.Cold press also is the hot press of common wood-based plate, and different is, and the cold press pressing plate feeds is cold water.The pressing plate of described hot press, cold press is hollow heating platen, and quantity is all 8～16.Assembling die behind the cooling and shaping unloads by unloading trigger, and product is taken out in die sinking then.

The advantage that the utlity model has: the wood after common synthesizing is moulded the manufacture that particle adopts the wood-based plate streamline, be combined into a kind of green, environmental protection, and new material that can 100% recycled for multiple times, and have that area is big, density is high, intensity is high, waterproof, characteristic such as nontoxic, formaldehydeless.The Wood plastic boards of being produced has that area is big, density is high, waterproof, nontoxic, formaldehydeless characteristic, but this sheet material rectangle, square, circle, abnormity etc., the highest size value 3000 * 5000mm of sheet material, diameter 5000mm; Heated-air drying has overcome the shortcoming that preheating and drying only heats up and do not dewater, and the gear-like rectangular sealed material roller of mating formation has overcome the shortcoming of cylinder, the starlike material roller leakage current matter particulate material of mating formation.

Use upper padding plate, lower bolster, material can whole mobile adhesion heating platen, upper padding plate, lower bolster, middle framed on spray oil and oil emulsion, the technology utilization of laying barrier paper, material adhesion mould is beneficial to the demoulding., the design of a plurality of spreading machines of line is beneficial to the reinforcement of mating formation of compound glass fiber or its cloth products.

To adorn trigger, hot press, push-and-pull trigger, cold press, unload trigger one design synchronously at grade, material slaking, cooling and shaping two machine duplexs have been realized, the action of five steps is finished automatically, improved the continuity that assembling die moves, stability, improved production efficiency.
