But, disclosed cavity adjustment component insufficient disclosure in its description in this patent documentation, therefore, those skilled in the art cannot realize according to the record of description.
Utility model content
In order to overcome above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of simple and practical, strong operability, enforceable and can regulate according to coating sizing-agent rheological behavior the adjustable extrusion coated head of slurry flow of painting parameter.
The technical solution of the utility model is: provide a kind of slurry flow adjustable extrusion coated head, comprise upper die head, lower die head, between described upper die head and lower die head, be provided with the pad that forms coating gap, in described lower die head, be provided with a charging die cavity and at least one refining die cavity, charging aperture communicates with described charging die cavity, described pad comprises shim body and flow deflector more than a slice, one end of described flow deflector is connected or adjacency with the inner side of described shim body, the other end of described flow deflector extends towards the direction of described refining die cavity, and extend to described charging die cavity and be close in the gap of refining die cavity of charging die cavity.
As to improvement of the present utility model, described flow deflector is evenly spaced apart.
As to improvement of the present utility model, described flow deflector is more than three, is arranged symmetrically with the symmetry axis of described shim body.
As to improvement of the present utility model, described flow deflector is the thinning setting gradually to both sides centered by described symmetry axis.
As to improvement of the present utility model, the free end of described flow deflector is tongue state.
As to improvement of the present utility model, it is trapezoidal that described flow deflector is on the whole.
As to improvement of the present utility model, the shim body of described pad and flow deflector are shaped with a material monolithic.
As to improvement of the present utility model, the shim body of described pad and flow deflector are two parts, adjoin each other.
As to improvement of the present utility model, described pad is that plastics, silica gel or rubber are made.
The utility model is to comprise shim body and flow deflector more than a slice owing to having adopted gasket design, one end of described flow deflector is connected or adjacency with the inner side of described shim body, the other end of described flow deflector extends towards the direction of described refining die cavity, and extend to the structure in the gap of described charging die cavity and the refining die cavity of next-door neighbour's charging die cavity, like this, just the slurry in slurry die cavity can be divided into plural charging aperture, according to the characteristic difference of slurry, can design in advance different pads, only need be for the characteristic of different slurries, and the different pad of choice for use, the utility model adopts flow deflector to be combined with shim body, it has makes easily, simple and practical, strong operability, the advantage that implementation is strong.In addition, by the thinning setting gradually to both sides centered by described symmetry axis of described flow deflector, can reduce center pressure, and increase both sides flow, realize the uniform object of coating.Again, the free end of flow deflector is tongue state or trapezium structure described in Dou, is conducive to slurry and flows into refining die cavity, and the new slurry flowing into can not produce dry sorrow to the slurry in refining die cavity.

Detailed description of the invention
Refer to Fig. 1 and Fig. 2, what Fig. 1 and Fig. 2 disclosed is the adjustable extrusion coated head of a kind of slurry flow, comprise upper die head 1, lower die head 2, between described upper die head 1 and lower die head 2, be provided with the pad 4 that forms coating gap 3, in described lower die head 2, be provided with a charging die cavity 21 and a refining die cavity 22(also can establish several refining die cavities 22 as required), charging aperture 23 communicates with described charging die cavity 21, described pad 4 comprises that shim body 41 and multi-disc flow deflector 42(also can establish a slice, if when a slice, preferably be positioned at the centre of charging die cavity), one end of described flow deflector 42 is connected (adjacency state can referring to Fig. 7 or Fig. 8) with the inner side 43 of described shim body 41, the other end of described flow deflector 42 extends towards the direction of described refining die cavity 22, and extend to the interior (see figure 1) in gap 44 of described charging die cavity 21 and the refining die cavity 22 of next-door neighbour's charging die cavity 21.
Refer to Fig. 3, described flow deflector 42 is evenly spaced apart, in the present embodiment, evenly to arrange along the symmetry axis 45 of described shim body 41, like this, be equivalent to an original runner mouth to become plural runner mouth, be conducive to regulate material to be pressed, to be suitable for the slurry of different qualities.In the present embodiment, described flow deflector 42 is more than three, is arranged symmetrically with the symmetry axis 45 of described shim body 41.
Refer to Fig. 4, described flow deflector 42 is the thinning setting gradually to both sides centered by described symmetry axis, be conducive to like this slurry that intermediate pressure is higher and flow to both sides, reach both sides and press all permanent effect, be good for the uniformity of the coating thickness of coating machine.
Refer to Fig. 5, the free end of described flow deflector 42 is tongue state, is conducive to like this pulp flow.Same reason, it is trapezoidal that described flow deflector 42 can be designed to be on the whole, refers to Fig. 6.
The shim body 41 of described pad 4 and flow deflector 42 are to be shaped with a material monolithic, are so convenient to make, and described pad 4 can be made with plastics, silica gel or rubber.
The shim body 41 of described pad 4 and flow deflector 42 are two parts, and both adjoin each other, and so design will be if desired, only needs to change flow deflector 42 parts, can more save use cost (referring to Fig. 7 and Fig. 8).
