Description
Technical field
The utility model relates to tape-casting field, in particular to a kind of curtain coating valve and the painting for having the curtain coating valve arrange
It sets.
Background technique
In electronic component, ceramic insulation substrate, ceramic substrate, dielectric layer, protective layer, ion diaphragm especially fire
The cationic membranes of material battery are usually that the tape casting is used to prepare: slurry first is made in raw material, is flowed on casting machine after processing
Prolong into diaphragm green compact, using drying, form by a firing.
Curtain coating valve is on casting machine for being coated with the mechanism of solution, and the important mechanism of decision quality of forming film.It is existing
Curtain coating valve generally uses overflow-type to be cast valve.
Chinese patent if Authorization Notice No. is CN2816041Y discloses a kind of overflow-type casting device, including curtain coating
Slot, roll shaft, board-like scraper, curtain coating slot connect slurry transport lines, forward and backward weir divider are arranged in curtain coating slot, baffle is located at
Adjustable overflow gap is formed above preceding weir divider and between baffle bottom and preceding weir divider top.
Its feed liquor and out liquid coating all directly result from liquid level surface layer, during duration feed liquor, the surface layer of solution
Change in flow will be generated and form surge effect, is i.e. feed liquor will be coated with liquid out and generate impact, directly affect the steady of solution coating
It is qualitative, film-forming accuracy is finally influenced, continuity is poor after film forming.
Utility model content
The mesh one of the utility model is to provide a kind of curtain coating valve, and which solve curtain coating valves to be cast unstable problem, reaches
Stablize to curtain coating, be coated with uniform effect.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of curtain coating valve, including matrix are provided with the reservoir and stream that arranged adjacent is separated by partition in described matrix
Prolong slot, the valve of the liquid outlet opening and closing of control curtain coating slot；The lower part of the partition is placed with multiple connection liquid storages in the horizontal direction
Slot connects hole with curtain coating slot, and the inlet of the reservoir is located at the top of reservoir.
Using the above scheme, curtain coating and feed flow are divided into two cavities first, are then connected to two chambers by connecing hole,
Middle feed flow and feed liquor are completed in reservoir, but since feed liquor is on the top of reservoir, and feed flow is in the lower part of reservoir, phase
Can effectively be reduced by fluctuation caused by feed liquor to feed flow and be coated with out liquid for the liquid mode out of traditional top Overruning
De-stabilising effect, thus the effective uniformity for improving curtain coating, improves film quality；Additionally due to influence of fluctuations subtracts
It is few, liquid, feed liquor movement successional can be completed out, film efficiency is improved.

It is able to maintain good stability during sliding up and down, can accurately complete to abut with the seamless of bottom plate, and cylinder pushes away
The mode that conjunction valve plate closes a floodgate of providing and delivering can quickly finish opening and closing.
Further preferably are as follows: the motion track of first valve plate is the vertical or vertical slot bottom in curtain coating slot.
Using the above scheme, good truncation effect can be obtained.
Further preferably are as follows: the valve further include along partition surface sliding be used for block connect hole the second valve plate and
It is fixed on the second push cylinder on matrix for driving the second valve plate mobile.
Using the above scheme, the second valve plate and the first valve plate can both be completed at the same time switching motion, can also be respectively completed
Switching motion；When it is completed at the same time opening and closing so that starting coating every time, the amount of solution being cast in slot can be protected always
Hold the flow velocity that in the constant level told somebody what one's real intentions are, can also be kept constant；When what it was respectively completed opening and closing can complete quantitative coating, i.e.,
It is cast when closing liquid outlet and starts to accumulate solution in slot, closing connects hole when then coating.
Further preferably are as follows: first valve plate include end contacted with upper guide surface guide plate, be overlapped in and lead
To the abutting plate of plate；When the guide plate is abutted with guide surface, the end for abutting plate is abutted with the slot bottom of curtain coating slot.
Using the above scheme, increase the area for abutting sealing, and will be between upper guide surface and end plate when closing
Solution squeezes out, and the situation of dispersion dropping liquid is prevented to generate.
Further preferably are as follows: the valve includes the datum plate being fixed on matrix, the first valve for closing liquid outlet
Plate, at least two the first push cylinders for driving the first valve plate mobile；First push cylinder is fixed on the basis of datum plate
In on datum plate plate, the piston rod of first push cylinder passes through datum plate and connect with the first valve plate；The curtain coating valve includes
The bottom plate and composition curtain coating end plate of the slot far from reservoir side cell wall, the end plate for forming the curtain coating slot slot bottom are lower than other
Other side walls of slot are cast, and the end of the end plate is respectively equipped with inclined interior guide face and outer guide face；When closing, described first
The end of valve plate is contacted with interior guide face and outer guide face simultaneously.
Using the above scheme, the damping of shocks generated feed liquor in reservoir, and to connect hole uniformly defeated using multiple
It send to curtain coating slot, good liquid stability out can be kept by then being overflowed by the top of end plate, and China and foreign countries' guide face can be again
Once to the fluid cushion of spilling, to reinforce the stationarity overflowed；In addition, corresponding valve plate bottom is rendered as inverted triangle, closing
When the solution on outer guide face can be squeezed out, prevent drop from generating.
The mesh two of the utility model is to provide a kind of apparatus for coating for having the curtain coating valve, including lifting frame, at least two
A the first lifting assembly being fixed in lifting frame is driven the scraper plate moved up and down by the first lifting assembly, and the curtain coating valve is solid
