But cavity adjustment component insufficient disclosure in its description disclosed in this patent document, therefore, those skilled in the art cannot realize according to the record of description.
Summary of the invention
In order to overcome above-mentioned problems of the prior art, the object of this invention is to provide a kind of simple and practical, strong operability, the enforceable and extrusion coated head that the slurry flow of painting parameter can be regulated adjustable according to coating sizing-agent rheological behavior.
Technical scheme of the present invention is: provide the extrusion coated head that a kind of slurry flow is adjustable, comprise upper die head, lower die head, the pad forming coater gap is provided with between described upper die head and lower die head, a charging die cavity and at least one refining die cavity is provided with in described lower die head, charging aperture communicates with described charging die cavity, described pad comprises the flow deflector of more than shim body and a slice, one end of described flow deflector is connected with the inner side of described shim body or adjoins, the other end of described flow deflector extends towards the direction of described refining die cavity, and extend to described charging die cavity with in the gap of the refining die cavity of next-door neighbour's charging die cavity.
As improvement of the present invention, described flow deflector is that uniform intervals is arranged.
As improvement of the present invention, described flow deflector is more than three, is arranged symmetrically with the symmetry axis of described shim body.
As improvement of the present invention, described flow deflector is the thinning setting gradually to both sides centered by described symmetry axis.
As improvement of the present invention, the free end of described flow deflector is tongue state.
As improvement of the present invention, described flow deflector is on the whole in trapezoidal.
As improvement of the present invention, the shim body of described pad and a flow deflector material monolithic are shaped.
As improvement of the present invention, the shim body of described pad and flow deflector are two parts, adjoin each other.
As improvement of the present invention, described pad is plastics, silica gel or rubber are made.
The present invention is the flow deflector comprising more than shim body and a slice owing to have employed gasket design, one end of described flow deflector is connected with the inner side of described shim body or adjoins, the other end of described flow deflector extends towards the direction of described refining die cavity, and extend to described charging die cavity and the structure in the gap of 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, different according to the characteristic of slurry, different pads can be designed in advance, only need for the characteristic of different slurry, and the pad that choice for use is different, the present invention adopts flow deflector to be combined with shim body, it has making 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 center pressure be reduced, and increase both sides flow, realize the uniform object of coating.Again, described in Dou, the free end of flow deflector is tongue state or trapezium structure, is conducive to slurry and flows into refining die cavity, and the new slurry flowed 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, the extrusion coated head that a kind of slurry flow that what Fig. 1 and Fig. 2 disclosed is is adjustable, comprise upper die head 1, lower die head 2, the pad 4 forming coater gap 3 is provided with between described upper die head 1 and lower die head 2, a charging die cavity 21 is provided with and a refining die cavity 22(also can establish several refining die cavities 22 as required) in described lower die head 2, charging aperture 23 communicates with described charging die cavity 21, described pad 4 comprises shim body 41 and number of guide sheet 42(also can establish a slice, if during a slice, preferably be positioned at the centre of charging die cavity), one end of described flow deflector 42 is connected with the inner side 43 of described shim body 41 (adjacency state can see Fig. 7 or Fig. 8), the other end of described flow deflector 42 extends towards the direction of described refining die cavity 22, and extend to described charging die cavity 21 and (see figure 1) in the gap 44 of the refining die cavity 22 of next-door neighbour's charging die cavity 21.
Refer to Fig. 3, described flow deflector 42 is that uniform intervals is arranged, in the present embodiment, evenly arrange along the symmetry axis 45 of described shim body 41, like this, be equivalent to original runner mouth to become plural runner mouth, be conducive to regulating material pressure, 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, the slurry being conducive to intermediate pressure so higher flows to both sides, and reach the effect that both sides pressure is all permanent, the uniformity for the coating thickness of coating machine is good.
Refer to Fig. 5, the free end of described flow deflector 42 is tongue state, is conducive to pulp flow like this.Same reason, described flow deflector 42 can be designed to, on the whole in trapezoidal, refer to Fig. 6.
The shim body 41 of described pad 4 and flow deflector 42 are shaped with a material monolithic, and be so convenient to make, 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 if desired, only will need be changed flow deflector 42 part, more can save use cost (see Fig. 7 and Fig. 8).
