Abstract
The invention discloses a merging core for extrusion moulding machine, characterized in that the merging core is provided with a guide pore, the cavity of which is provided with a guide device which can either be straight grid tray or broken line gird plate, and which can also be vertical tooth-staggered grid tray; the guide pore can also be conic, and the width of inlet ends of grid pores between the straight grid trays is larger than the width of outlet ends. As a component for wood-plastic composite extrusion moulding equipment, the merging core can enhance the quality of articles and is suitable for the extrusion moulding of wood-plastic composite extrusion moulding machine.
Description
Technical field
The present invention relates to the extrusion equipment parts, especially a kind of merging core for extrusion moulding machine.
Background technology
Wood plastic composite is by the modified plastics tread flaking, but the processing request of wood plastic composite and plastics are very different.And existing wood plastic composite process equipment, Wood-plastic composite material extrusion moulding machine tool for example adopts the structure of existing plastic processing machinery substantially.Facts have proved that wood plastic composite is as the new material with autonomous behavior, its processing technology difficulty is considerably beyond the common plastics goods, and production equipment is the more and more specialized and particularization of tendency also.The deficiency of existing equipment is:
In the wood plastic composite extrusion, the arrangement of the string in the material is at random, in the extrusion process process turbulent flow, accumulation or lamination can take place, and influences Products Quality.And the orderly arrangement of the string in the material, the orientation of putting up a bridge have very big improving to the physical characteristic of wood plastic product.How allowing the string in the wood plastic product take place to arrange to improve quality of item in order, is the problem that the present invention puts forth effort to solve.
Summary of the invention
The purpose of this invention is to provide a kind of merging core for extrusion moulding machine, to solve the above-mentioned deficiency of existing Wood-plastic composite material extrusion moulding equipment.Merging core of the present invention is a kind ofly can improve crudy, efficient, guarantees the merging core that the stable extrusion equipment of product size is used.
The present invention realizes that by following proposal merging core for extrusion moulding machine of the present invention is positioned at the exit of machine barrel, it is characterized in that: have pod apertures on the described merging core, have guiding device in the vestibule of described pod apertures.
Described guiding device can be straight screen, or broken line shape screen, or upper and lower bayonet-type screen.
Or described guiding device is the fusiformis cross section screen that entrance point is big, the port of export is little, is fan-shaped array in merging core.
Or described pod apertures is round taper hole, and the width of the entrance point in each the grid hole between each described straight screen is greater than the width of the port of export.
The present invention has adopted comb formula guiding device in the merging core section, make melt material by merging core the time, obtain the combing guiding, having improved string arranges and orientation in order, problems such as product unbalanced stress that causes to reduce the turbulent flow of melt material before typing, conglomeration and layering reach the purpose that product size is stable and physical property improves.
In sum, merging core of the present invention can solve the deficiencies in the prior art, and merging core of the present invention is a kind of extrusion molding parts that improve crudy efficient, guarantee the special-purpose wood plastic composite that product size is stable that have.The present invention is applicable to height and adds the extrusion molding processing that living beings plasticizing raw material is the wood plastic composite of base-material also be applicable to PVC, PE, PP, ABS and PET etc. to be the extrusion molding processing of the non-plasticizing biomass material of base-material.

The specific embodiment
Fig. 1 is the schematic diagram that the twin-screw extrusion shaping machine 1 of merging core of the present invention is housed, and comprises motor 1-2, reduction gear box 1-3, distribution gear case 1-4, feeding device 1-5, machine barrel 1-6, extruding screw 1-7, merging core 1-9, preheating apparatus 1-10.Motor 1-2 drives this extruding screw 1-7 through reduction box 1-3, distributor box 1-4; The outlet of feeding device 1-5 inserts the charging aperture of machine barrel 1-6, and to machine barrel 1-6 feeding, extruding screw 1-7 is contained in the machine barrel 1-6, through the extruding of extruding screw 1-7, material is extruded from merging core 1-9.
Fig. 2 is merging core 1-9 among Fig. 1 and the axial section enlarged drawing of machine barrel 1-6, and the structure of merging core 1-9 is shown, and described merging core 1-9 is positioned at the discharging opening place of machine barrel 1-6, and 1-12 is contained in the end of machine barrel 1-6 with it with the locking collar; Have pod apertures on the merging core 1-9, the cross section of described pod apertures can be circle or ellipse; In the vestibule of pod apertures, has guiding device 1-9-0.Fig. 3,4,5 is the C-C cutaway view Amplified image among Fig. 2.As Fig. 3, shown guiding device is made straight screen 1-9-1, promptly straight screen and the adjacent layout in straight grid hole.As Fig. 4, shown guiding device is made broken line shape screen 1-9-3.As Fig. 5, shown guiding device is made upper and lower bayonet-type screen 1-9-2.As Fig. 6 is the axial section enlarged drawing of the merging core 1-9 among Fig. 2, and shown guiding device is made the screen 1-9-4 in the fusiformis cross section that entrance point is big, the port of export is little, is fan-shaped array in merging core.In addition, the pod apertures on the merging core 1-9 as shown in Figure 2 also can be round taper hole, each straight grid hole between the straight screen 1-9-1 of each shown in Fig. 3 then, and the width of its entrance point is greater than the width of the port of export.
The effect of above-mentioned each guiding device is to mould melt by merging core the time when wood, guiding device can guide wherein the fiber orientation of arranging in order, put up a bridge, reduce wood mould melt before typing because problems such as product unbalanced stress that turbulent flow, conglomeration cause and layerings, to reach the purpose of the stable and physical property raising of product size.
