The boss of setting, the groove that be provided at both ends with and the boss of roller shell are mutually clamped.
Using the coating machine in above patent document by organic substance solution coating when on matrix, due to liquid slurry
Solid content is low, poor fluidity, viscosity is high, causes slurry crawling, film forming thickness and film forming width to be difficult to control.Meanwhile
Since the slurry chemical property of different systems differs, simple coating need different matrix material with prevent slurry run material, segregation and
Adhesion, so as to cause that production cost is higher, film yield rate is low.
The content of the invention
The present invention is for the above problem existing for existing technology, there is provided a kind of continuous film coating machine, the present invention want
The technical problem of solution is：How to ensure that different matrix material can quickly, uniformly be coated solution and improve coating
The convenience of control.
The purpose of the present invention can be realized by following technical proposal：
A kind of continuous film coating machine, including can rotate preliminary roller and back roller, can be moved between preliminary roller and back roller
Matrix, it is characterised in that offered on the preliminary roller and the side face of back roller annular in shape along its circumferential groove, described matrix
And matrix both ends are looped around the preliminary roller and the groove of back roller respectively, the outer surface of described matrix is offered along length thereof side
To annular groove；The top of the preliminary roller is equipped with charging basket, and the charging basket is provided with described matrix close to the side of the back roller
The scraper of upper annular groove, the matrix periphery between the preliminary roller and back roller are equipped with baking oven, and the side of the back roller is equipped with reel.
Its principle is as follows：It is placed in advance in slurry in charging basket, preliminary roller, back roller and reel are linkage, linear velocity phase
With to ensure identical membrane and rolling speed.Turn on the power switch, preliminary roller, back roller are operated according to certain speed, and baking oven starts
Work.At this time, charging basket switch is opened, slurry starts to flow out from charging basket, into the annular groove on matrix, and as matrix is held
Continuous movement, slurry are coated with expansion in the annular groove of matrix, and when being moved to below scraper, scraper closely connects with body upper surface
Touch, unnecessary slurry is stopped, so that ensure that the slurry thickness on matrix is uniform, and the width that slurry is coated with receives annular groove
The limitation of width, it is convenient accurately to control film forming width.Slurry with specific thicknesses and specific width enters baking oven, is drying
It is oven-dried under the heating of case, the solvent volatilization in slurry, so that the solid matter in slurry is shaped as, thickness is uniform, has spy
The film of fixed width degree.Film is uncovered after baking oven comes out by craft from matrix, and is sent into reel and is wound up, and hereafter should
Device is continuously run, and completes the continuous production of film.Continuous film coating machine in the present invention can effectively avoid slurry from applying
Material, segregation and adhesion are run during cloth, by using the coated substrates with annular groove, it is had wide range of applications, effectively keeps away
Exempt from the replacement flow of coated substrates, shortened membrane material and the time is made, reduce production cost, and can realize film forming thickness
And effective control of film forming width.
In above-mentioned continuous film coating machine, described matrix is conveyer belt, and the annular groove is located at described matrix width
Medium position on direction；Spacing between the two lateral extent matrix both sides of the edge of annular groove is equal；When described matrix is surround
In the preliminary roller and/or the groove of back roller, the outer surface of described matrix is equal with the periphery of the preliminary roller and/or back roller
Together.
In above-mentioned continuous film coating machine, the bottom surface of the annular groove is plane, or is the annular groove
