Abstract
The utility model discloses a kind of precise extruding mold head of coating machine, including upper die and lower die and gasket, upper die and lower die, which are engaged, to be coupled, and gasket is mounted between upper die and lower die.Slurry inlet and hopper are equipped in lower die, slurry inlet passes through lower die and is connected with hopper, and several accurate scrapers are equipped in hopper.Slurry from slurry inlet enter hopper after by accurate scraper by repeatedly striking off, after hopper pressure balance, it is consistent to obtain height for pressure after when into slit, slurry is after slit extrusion to lip, so that transverse direction coating layer thickness reaches height unanimously when squeezing out, achieve the effect that accurate coating, to thoroughly solve the problems, such as that coating transverse gage thick middle and both sides are thin, and accurate coating head is made to have more wide applicability to the viscosity and coating speed of slurry.
Description
Technical field
The utility model relates to coating art more particularly to a kind of precise extruding mold heads of coating machine.
Background technique
Coating machine is widely used among the industries such as electronics, photovoltaic, printing, weaving, leather, and especially accurate coating industry is such as
Film, lithium battery pole slice, permeable membrane, optical film etc..Core main part as coating machine -- slit extrusion die was using
Since general slurry is non-newtonian fluid in journey.Because the effect slurry of shearing force cannot rapidly and evenly divide after entering hopper
Cloth generally will appear the thin phenomenon in coating thick middle both sides in hopper.Have using a variety of methods and improve, such as into
The mesh plate that dilute both sides are close among one is placed at material, or using dovetail groove or extrusion is processed into the shapes such as the narrow intermediate width in both sides
Shape, or lip gap size is adjusted with row's screw to reach the consistent as far as possible of coating thicknesses of layers.But no matter which kind of above-mentioned side
Method is only applicable to a kind of coating of the slurry of similar viscosity and certain extruded velocity, does not have universal applicability, right
The slurry adjustment of different viscosities, different coating speed is got up relatively highly difficult, and some methods may cause the quite high mould of cost
Tool is whole to be scrapped.The utility model provides the technical solution of complete set aiming at this problem.
Utility model content
In order to solve the problems of the above-mentioned prior art, the utility model proposes a kind of Precise Extrusion moulds of coating machine
Head.
The technical solution of the utility model is achieved in that
A kind of precise extruding mold head of coating machine, including upper die and lower die and gasket, the upper die and lower die are engaged cooperation peace
Dress, the gasket are mounted between the upper die and lower die, which is characterized in that slurry inlet and hopper are equipped in the lower die,
The slurry inlet extends to hopper outside the lower die, is equipped with accurate scraper in the hopper, the precision scraper with it is upper
Gap is 10-300 μm between mould bottom surface, and the precision scraper is 1-5 handle.
In the precise extruding mold head of this coating machine of the utility model, it is described precision scraper and upper mold bottom surface between
Gap is 100-200 μm.
In the precise extruding mold head of this coating machine of the utility model, the precision scraper is 3.
In the precise extruding mold head of this coating machine of the utility model, the edge of a knife shape of the precision scraper is plane
Shape is arc-shaped or trapezoidal knife-edge.
In the precise extruding mold head of this coating machine of the utility model, it is described precision scraper with a thickness of 8-20cm.
The precise extruding mold head for implementing this coating machine of the utility model, has the advantages that slurry from slurry
Entrance enters after hopper by accurate scraper by repeatedly striking off, after hopper pressure balance, when into slit after pressure obtain height
Degree is consistent, and slurry, to lip, so that laterally upper thickness is consistent coating when squeezing out, reaches accurate coating after slit extrusion
Effect, to thoroughly solve the problems, such as that extrusion die transverse gage thick middle and both sides are thin.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Fig. 1 to 5, the precise extruding mold head of this coating machine of the utility model, including upper mold 10,11 and of lower die
Gasket 12, upper mold 10 and lower die 11 are engaged and are coupled.Upper mold 10 and lower die 11 are in a rectangular trapezoid, and gasket 12 is mounted on upper mold 10
Between lower die 11, gasket 12 is in concave character type, and notch position has at bevelled one in upper mold 10 and lower die 11, is convenient for slurry
It is squeezed out from the hopper 14 of lower die 11.
Slurry inlet 13 and hopper 14 are equipped in lower die 11, slurry inlet 13 extends to hopper 14 outside lower die 11.
Slurry inlet 13 and the angle of 11 outside wall surface of lower die are in 60 °.Convenient in slurry input hopper 14, having a certain degree can be effective
Control slurry flow velocity.Accurate scraper 15 is equipped in hopper 14, accurate scraper 15 is equipped with 3, precision is enabled to obtain
It improves, it is more stringent for precision requirement, it can also be plus more accurate scraper 15.The edge-shaped of accurate scraper 15 simultaneously
Shape can be that planar shaped is arc-shaped or trapezoidal, be convenient for the scraping of slurry in this way.Accurate scraper 15 with a thickness of 8-20cm.It is accurate
Gap is 100-200 μm between scraper 15 and the bottom surface of upper mold 10.Convenient for accurate 15 convenient disassembly of scraper, screw is preferably used
It is fixed.And the precise extruding mold head applies also for curtain coating extrusion die.
The precise extruding mold head of the coating machine when in use, first by entering slurry from slurry inlet 13, then again
Into in hopper 14, it is unfolded forward through accurate scraper 15, because gap very little, slurry fill quickly between accurate scraper 15 and upper mold 10
Then full first hopper 141 enters the second hopper 142 by the first accurate scraper 151, pressure balances for the second time.Slurry pressure
It gradually homogenizes, enters third hopper 143 by the second accurate scraper 152, the 4th is being entered after third precision scraper 153
The pressure of hopper 144, entire laterally upper each point is identical, therefore flow velocity can achieve almost unanimously when extrusion die lip,
So that being all consistent among coating with the thickness on both sides.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, made any modification, equivalent replacement and improvement etc. should be included in the utility model
Protection scope within.
