Description
Technical field
The present invention relates to a kind of improvement of extrusion coated head, especially a kind of curve type applies the extrusion leftover of bolt of cloth.
Background technology
Existing extrusion coated head, as shown in Figure 1, lip 200 is coated with including the first coating lip 100 and second, described the
One coating lip 100 and second is equipped with gasket between being coated with lip 200, and the gasket is coated with lip 100 and second by described first and is coated with
Lip 200 separates to form coating slit 300, is coated in lip 200 on a coating lip in the first coating lip 100 and second and is equipped with hopper
310, the hopper 310 is communicated with the coating slit 300.This extrusion coated head it is horizontally disposed or sideling upwards arrangement
When, Painting effect or satisfactory.But this extrusion coated head is straight downwards or when sideling arrangement downwards in weight,
It just will appear trailing phenomenon, when so-called trailing phenomenon is exactly intermittent coating, when wanting centre to stop applying, slurry cannot stop immediately
Only, a small amount of hangover coating phenomenon gone out, this trailing phenomenon is not allow in the intermittent coating process of electrode of lithium cell
's.
There is the reason of trailing phenomenon mainly and has and is following several in vertically downward or sideling arrangement downwards in extrusion coated head
Point：When the resistance to slurry of the first coating lip 100 and second coating 200 opposite face of lip, second is that hopper 300 is remaining when stopping applying
Pressure of the remaining slurry to the slurry in slit 400.When stopping applying, if slurry is equal to the pressure of the slurry in slit 400
Or the resistance to slurry of 200 opposite face of lip is coated with less than the first coating lip 100 and second, then be not in discharge port 500
Trailing phenomenon, conversely, just will appear trailing phenomenon.Further think, the first coating lip 100 and second is coated with 200 phase of lip
The resistance to slurry on opposite is decided by that two factors, first factor are that the first coating lip 100 and second coating lip 200 is opposite
The finish in face if to obtain larger resistance, needs getting over for the first coating lip 100 and second coating 200 opposite face of lip certainly
Coarse better, second factor is the viscosity of slurry.In the practical manufacturing process of extrusion coated head, it is contemplated that other when coating
Painting effect, such as coating uniformity, coating it is more more uniform better；In coating process, the pulp layer being coated with out will cannot occur
Spot caused by bubble etc., finish will be made to the first coating coating 200 opposite face of lip of lip 100 and second, and the higher the better；
And the viscosity of slurry, for each slurry, its viscosity is certain, cannot at will be changed.
Therefore, remaining slurry to the pressure of the slurry in slit for causing trailing phenomenon to be affected when coating.
Invention content
For the disadvantages described above or Improvement requirement of the prior art, the present invention provides one kind can prevent from trailing when coating,
And it is suitable for the curve type vertically downward or being sideling coated with downwards and applies the extrusion leftover of bolt of cloth.
The technical scheme is that：A kind of curve type painting extrusion leftover of bolt of cloth, including the first coating lip and the second coating are provided
Lip, is equipped with gasket between the first coating lip and the second coating lip, and the gasket is coated with lip and second by described first and applies
Cloth lip separates to form coating slit, and the coating slit is divided into the two-section for being sequentially connected and connecing, and first section of coating slit is narrow to face directly
Seam, the lower end for facing slit directly are discharge port；Second section of coating slit is cambered surface slit, is equipped on cambered surface slit and is communicated with slit
Hopper.
As improvement of the present invention, the hopper is arranged at the high point of the cambered surface slit.
As improvement of the present invention, in the cambered surface slit, far from slit side is faced directly, to set the extension that is upturned narrow
Seam.
As improvement of the present invention, the extension slit is to face slit directly.
As improvement of the present invention, the extension slit is cambered surface slit.
As improvement of the present invention, the angle α faced directly between slit and horizontal plane selects between 30 degree to 90 degree
It selects.
As improvement of the present invention, contact site is equipped on the coating lip of the side far from discharge port.
As improvement of the present invention, the bottom surface of the contact site is plane or cambered surface.
The present invention is divided into the two-section for being sequentially connected and connecing as a result of the coating slit of coating head, and first section of coating slit is
Face slit directly, the lower end for facing slit directly is discharge port；Second section coating slit be cambered surface slit, on cambered surface slit be equipped with it is narrow
The structure of hopper communicated is stitched, so, the present invention has and can prevent from trailing when coating, and is suitable for vertically downward or sideling
Downwards the advantages of coating.
