Background technology
Wood is moulded as a kind of novel green product, becomes market in recent years and pays close attention to and enterprise's hot of research and development.At present, wood-plastic products mostly adopts the production technology of extrusion molding.Yet, because wood powder or other biological material is coarse, frictional force is big, mobile poor, so the plastics ratio must more than 70%, wood substance component must be in the ordinary production of ability below 30%.The result is to use the plastics ratio big, and wood effect is undesirable, and production cost is higher, and a lot of enterprise operation situation are pessimistic.
If adopt the production technology of compression molding, then has only the sheet material that uses mould ability production given size.Because it is plastics that wood is moulded the binding agent of plate, even add wood materials, under HTHP, also can be excessive because having certain flowability.For the continuity that guarantees that die press technology for forming is produced, all need use a lot of moulds to produce on the production line of at present a lot of enterprises, therefore there is following defective:
1. energy consumption is big: the mould preheating of need heating, and after pressing, sheet material needs cooling and shaping again, and the mould of nearly hundred kilograms in cooling one cover of so heating repeatedly causes the consumption of huge energy;
2. efficient is low: preheated mold needs 30 minutes approximately to design temperature, greatly reduces production efficiency;
3. cost is high: equipment investment is big, floor space is wide.
Summary of the invention
The technical problem that the present invention will solve provides that a kind of energy consumption is little, efficient is high, cost is low, is used to produce the Wood-plastic mould pressing production line of high wooden content Wood plastic boards.
The present invention adopts following technical scheme to solve the problems of the technologies described above: Wood-plastic mould pressing production line of the present invention comprises feeder, hot-press forming device, cooling and shaping equipment and transfer system; Heating plate and following heating plate are installed on the hot-press forming device; Said going up between heating plate and the following heating plate is equipped with liftable single mode frame; Said cooling and shaping equipment is two covers, lays respectively at hot-press forming device both sides and continuous by transfer system; Said transfer system comprises chain and is installed in two blocks of supporting plates on the chain wherein have a supporting plate to place between the following heating plate and single mode frame of hot-press forming device, and another piece supporting plate is placed in one on the cover cooling and shaping equipment.
The length of said single mode frame be 1220 millimeters, wide be 2440 millimeters.
Said single mode frame is connected with the oil cylinder that control is gone up and down.
