Description
Technical field
The utility model relates to coating apparatus technical fields, and in particular to a kind of thermotropic viscosity-adjusting agent slot die.
Background technique
In the coating process of water soluble polymer quasi polymer, slot die is commonly used slurry and is uniformly applied to base
On film.Need to adjust the thickness of figure layer in process of production according to the actual situation, existing method generally uses screw to adjust mould
The width of lip slit, to achieve the purpose that adjust die lip load, but this regulative mode needs to stop coating process, adjustment
It can just continue to be coated with after good slit width, be unfavorable for serialization and automated production.
Utility model content
Slot die needs to adjust feed liquid by screw in coating process in order to solve water soluble polymer quasi polymer
The technical issues of being unfavorable for continuous and automatic production caused by load, the utility model provide a kind of thermotropic viscosity tune
Save slot die.The technical solution of the utility model is as follows:
A kind of thermotropic viscosity-adjusting agent slot die, including die body, the die body is interior to be equipped with liquid storage chamber, the liquid storage chamber connection
Inlet and liquid outlet, between the liquid storage chamber and the liquid outlet by slit connect, the slit along feed solution flow side
To several evenly arranged channels are provided with, water pipe is provided in the channel, described water pipe one end connects water inlet, another
End connection water outlet.
Further, the liquid storage chamber is cylinder.Slit is directed at the center of cylinder, is more advantageous to uniform discharge.
Further, the inlet is located at the bottom of the die body.Water soluble polymer quasi polymer feed liquid is from bottom
Liquid storage chamber is injected, bubble can be effectively prevent to generate as long as controlling injection rate.
The beneficial effects of the utility model are as follows: channel is arranged in crack two sides in the utility model, and is arranged in channel
Water pipe flows into the temperature of water in water pipe by control, changes the dynamic viscosity for flowing through the water soluble polymer quasi polymer of slit,
To control its flow, it is finally reached the purpose of control coating layer thickness, the utility model is simple and reasonable, does not need manually to adjust
Screw is saved, the i.e. controllable load of water temperature need to be only controlled, serialization, automation coating may be implemented.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of structural schematic diagram of thermotropic viscosity-adjusting agent slot die of the utility model；
In figure: 1- die body, 2- liquid storage chamber, 3- inlet, 4- liquid outlet, 5- slit, 6- water pipe, 7- water inlet, 8- water outlet
Mouthful.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model 1, to the technical scheme in the embodiment of the utility model into
Row clearly and completely describes, it is clear that and the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.
A kind of thermotropic 5 die head of viscosity-adjusting agent slit, including die body 1, the die body 1 is interior to be equipped with liquid storage chamber 2, the liquid storage chamber
2 connection inlets 3 and liquid outlet 4, are connected between the liquid storage chamber 2 and the liquid outlet 4 by slit 5, the edge of the slit 5
Feed solution flow direction is provided with several evenly arranged channels, and water pipe 6 is provided in the channel, and described 6 one end of water pipe connects
The mouth of a river 7 is tapped into, the other end connects water outlet 8.
Further, the liquid storage chamber 2 is cylinder.Slit 5 is directed at the center of cylinder, is more advantageous to uniform discharge.
Further, the inlet 3 is located at the bottom of the die body 1.Water soluble polymer quasi polymer feed liquid is the bottom of from
Liquid storage chamber 2 is injected in portion, bubble can be effectively prevent to generate as long as controlling injection rate.
Working principle: water soluble polymer aqueous solution is passed through liquid storage chamber 2 by inlet 3, then passes through slit 5
Reach liquid outlet 4 to be coated, the thickness being coated with as needed adjusts the water temperature being passed through in water pipe 6.When the biggish coating of needs
When thickness, the water of high-temperature is passed through in water pipe 6, water soluble polymer aqueous solution dynamic viscosity increases, and flow increases, and applies
The thickness of cloth is just larger；When needing lesser coating thickness, the water of lower temperature is passed through in water pipe 6, water soluble polymer is poly-
It closes object aqueous solution dynamic viscosity to become smaller, flow reduces, and the thickness of coating is just smaller.
The beneficial effects of the utility model are as follows: channel is arranged in crack two sides in the utility model, and is arranged in channel
Water pipe 6 flows into the temperature of water in water pipe 6 by control, and the power for changing the water soluble polymer quasi polymer for flowing through slit 5 is viscous
Degree is finally reached the purpose of control coating layer thickness, the utility model is simple and reasonable, is not required to very important person to control its flow
Work adjusting screw need to only control the i.e. controllable load of water temperature, serialization, automation coating may be implemented.
The above is preferred embodiments of the present invention, is not restricted to the utility model.To art technology
For personnel, the several improvements and modifications made without departing from the principle of the present invention also should be regarded as protection of the invention
Range.
