Description

Wood-plastic door cover door line PVC co-extrusion transfer apparatus

Technical field

The present invention relates to a kind of wood-plastic door cover door line production field, particularly a kind of wood-plastic door cover door line PVC co-extrusion transfer apparatus.

Background technology

In prior art the production technology of wood-plastic door cover door line be formed product extrude → scale blocks → blank stacks to district to be checked → by the equipment of separately joining, the blank polishing sanding of extruding → upper transfer film → finished product is stacked to district to be checked.

Be packaged into finished product after check.Need through six road production processes altogether, need 6 people's operations.Existing production technology is that wood is moulded combined door pocket, door line process is extruded, surperficial natural skinning, and scale blocks, and surface finish is done transfer film or printed patterns again.Shortcoming of the prior art is; Product needs repeatedly transhipment, time-consuming taking a lot of work, and product surface fineness is inadequate, has the air spots defectives such as projection, foaming and micropore, and the surface finish cost is high, even also be difficult to reach the effect of oil paint coating through polishing.

Chinese patent 201210090016.7 discloses a kind of wood-plastic co-extrusion door-window section bar, its production stage be coextrusion mold, cooling, the traction and the cutting, without transfer printing process, and capable transfer printing process cost is relatively high again in follow-up operation, and printing quality is difficult to reach best.The structure that its wood is moulded between inner sandwich layer and PVC-U layer is up-down structure, and the PVC-U layer can't be moulded inner sandwich layer for wood protection is provided.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of wood-plastic door cover door line PVC co-extrusion transfer apparatus, can realize co-extrusion transfer printing automatic continuous production, reduces production link, reduces costs steady quality.Further can enhance productivity, also can improve the appearance of product.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of wood-plastic door cover door line PVC co-extrusion transfer apparatus is comprised of following equipment:

Wood is moulded extruder, is used for extruding wood and moulds inner sandwich layer;

The PVC extruder is used for extruding the PVC clad;

Wood is moulded to mould with PVC co-extrusion mouth by wood between extruder and PVC extruder and is connected;

Mould with wood the moulding cooler that is connected with PVC co-extrusion mouth;

Heat transfer machine is set after the moulding cooler, is used for pattern transfer to surface of semi-finished;

Set gradually hauling machine, material cutting machine and collecting machine after heat transfer machine.

Described heat transfer machine is six heat transfer machines.

A kind of method that adopts above-mentioned equipment to carry out the transfer printing of wood-plastic door cover door line PVC co-extrusion comprises the following steps:

One, wood is moulded extruder and is extruded wood and mould inner sandwich layer;

Two, the PVC extruder is extruded the PVC clad;

Three, wood is moulded inner sandwich layer and PVC clad and is moulded with PVC co-extrusion interruption-forming wood by wood and mould PVC co-extrusion semi-finished product;

Four, by heat transfer machine with pattern transfer to half-finished surface;

Five, obtain the wood-plastic door cover door line finished product that wood is moulded the transfer printing of PVC co-extrusion after cutting out material and rewinding operation.

Described heat transfer machine is six heat transfer machines.

Inner sandwich layer moulded by described wood and PVC clad ratio by weight is 100:15-22.

Inner sandwich layer moulded by described wood and PVC clad ratio by weight is 100:18.

Described wood is moulded and is mixed with nano-sized carbon element powder in inner sandwich layer.

The top layer that described wood is moulded inner sandwich layer and PVC clad also is provided with the antioxidant layer.

Described antioxidant layer is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester and three [2,4-di-tert-butyl-phenyl] phosphite ester of 4.3-5:1 by weight ratio.

A kind of wood-plastic door cover door line PVC co-extrusion transfer apparatus provided by the invention, by adopting above-mentioned equipment and method, realize top layer PVC clad, wood is moulded the inner sandwich layer material, solve finished product air spots and surface micropore problem, and provide the basis of directly doing surface processing technique to later process.Realizing wooden moulding on the basis of PVC co-extrusion, its surface directly reaches the transfer film requirement, is not subject to the erosion of air due to the PVC clad of newly extruding, and this moment is more tight with the combination of transfer printing pigment.Save simultaneously polishing and transhipment stacking operation.To move after the scale material cutting machine, increase automatic transfer apparatus, the wood that wood is moulded the PVC co-extrusion is moulded combined door pocket, door line molding procedure and transfer printing process and is once completed.The quality of production is stable, and efficient is high, and surfacing is smooth meets consumers' demand.Seven road production processes in the inventive method are once complete only needs 2 people to operate.
