Technical field
The present invention relates to a kind of control device for being used to control coating die head, specifically a kind of extrusion coated die head pressure
Force control device.
Background technology
Coating is essential process in lithium ion battery production process, be also directly affect battery security, capacity,
The critical process of the properties such as uniformity；, it is necessary to by the pasty state viscous paste made in lithium ion battery production process,
Uniformly, continuously or discontinuously it is coated on base material, and ensures the consistency of thickness of each application place；Due to extrusion coater knot
Structure is simple, and equipment is compact, and space is saved, and the coating accuracy for debugging convenient and extrusion coater is high, and Painting effect is good, because
This, many producers are mainly coated using extrusion coating machine at present, however, the characteristic due to slurry in itself, in coating process
The rheological property of middle slurry can be changed, so as to have impact on the effect of coating, finally have impact on the quality of battery.
The content of the invention
It is good the technical problem to be solved in the present invention is to provide a kind of Painting effect, so as to ensure squeezing for battery quality uniformity
Extrusion cloth die pressure control device.
In order to solve the above-mentioned technical problem, extrusion coated die pressure control device of the invention, including upper die and lower die
Between the die cavity that is formed, be referred to as slurry chamber, the feedstock direction of slurry chamber, which is provided with plunger cavity, plunger cavity, is provided with energy
It is provided with the top of the plunger enough moved back and forth, plunger cavity and the servomotor for moving piston reciprocation, slurry is driven by driver
The side of chamber is additionally provided with the pressure sensor for detecting slurry pressure, and pressure sensor connects driver by controller,
Pressure sensor results in slurry chamber internal pressure and pressure value is transferred into servomotor by controller, by servomotor
Control the movement of plunger.
The linear bearing for ensureing plunger rectilinear movement is provided with the plunger cavity.
Connected between the slurry chamber and plunger cavity by flange, sealing gasket is provided between the flange.
After above-mentioned structure, because setting is positioned at the pressure sensor of slurry chamber side and by servomotor band
Dynamic plunger, pressure sensor connects driver by controller, thus when pressure sensor detects slurry chamber internal pressure
Afterwards, pressure value is transferred to servomotor by controller, by the movement of Serve Motor Control plunger, it is achieved thereby that extruding is applied
The control of cloth mold cavity pressure, it is ensured that internal slurry pressure is in constant value, so as to ensure that the consistent of extrusion coated
Property, improve Painting effect.
Brief description of the drawings
Fig. 1 is the structural representation of extrusion coated die pressure control device of the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, further is made to the extrusion coated die pressure control device of the present invention
Describe in detail.
It should be noted that in the description of the invention, it is necessary to explanation, unless otherwise clearly defined and limited,
Term " installation ", " connection ", " connected " should be interpreted broadly, for example, it may be connection is fixedly connected with or dismantles, or
It is integrally connected, can is mechanical connection or electrical connection;Can be joined directly together or by intermediary
It is indirectly connected to, can is the connection of two element internals.For the ordinary skill in the art, it can be managed with concrete condition
Solve concrete meaning of the above-mentioned term in the present invention.In addition, in the description of the invention, unless otherwise indicated, " multiple ", " some "
It is meant that two or more.
As illustrated, the extrusion coated die pressure control device of the present invention, including formed between upper mould 1 and lower mould 2
Slurry chamber 3, is coated in substrate surface after the slurry output of slurry intracavitary, realizes coating, the feedstock direction of slurry chamber 3 is provided with post
Fill in and the plunger 5 that can be moved back and forth is installed in chamber 4, plunger cavity 4, the top of plunger cavity 4 is provided with servomotor 7, servo electricity
Machine 7 moves piston reciprocation by the driving of driver 6, and the pressure that the side of slurry chamber 3 is additionally provided with for detecting slurry pressure is passed
Sensor 8, pressure sensor 8 connects driver 6 by controller 9, and pressure sensor 8 obtains slurry chamber internal pressure and by pressure
Value is transferred to servomotor 7 by controller 9, and servomotor 7 moves piston reciprocation by the driving of driver 6, so as to pass through post
Plug 5 moves back and forth the regulation for realizing internal pressure.
Further, the linear bearing 10 for ensureing plunger rectilinear movement, slurry chamber are provided with described plunger cavity 4
Connected between 3 and plunger cavity 4 by flange 11, sealing gasket is provided between the flange 11.
During specifically used, when pressure sensor 8 detect slurry cavity pressure it is too small when, pressure signal is passed through
Controller 9 is transferred to the driver of servomotor 7, drives servomotor 7 to act by driver 6, and servomotor 7 drives plunger
Move down, so as to increase the pressure of slurry intracavitary, vice versa, thereby ensure that slurry chamber internal pressure within the specific limits.
In addition, described extrusion coating machine can be various extrusion coating machines of the prior art, it can use most common
It is a kind of include discharge mechanism, coating head, apparatus for baking and receiving mechanism and the extrusion coating machine with feed back passage,
When extrusion coating machine is not coated with, the slurry continuously entered in coating head is flowed out by feed back passage, so that
