It is the most common type process in coating.
In the coating process of water system technique, slurry is in naked state, and coating duration is long to have Stability of Slurry
Certain to influence, in general northern spring and winter air relative humidity is less than 40%, since humidity is too low in air, coating
Hopper ullage moisture is readily volatilized in the process, causes to form certain viscosity gradient in slurry, change slurry viscosity and
Stability can cause slurry liquid level peeling under serious conditions, form little particle or aggregate, be easy the pole piece shape in coating
At little particle even cut, causes coated face density in coating process unstable, influence the consistency of pole piece, to influence battery
Chemical property and security performance.
Main improved procedure is to carry out humidification process to entire room by large-scale humidifier at present, makes entire room humidity
It maintains to a certain degree, this method cannot accurately control the humidity of slurry upper air in coating process, while need to put into
Many funds, energy consumption is big, and economic loss is caused to company.
Utility model content

The rotary speed of automatic adjustment power and nozzle accurately controls slurry upper air humidity, it is ensured that the consistency that slurry contains admittedly carries
The high consistency of coating.The stability of coat window slurry can be accurately controlled using the method that coating machine head humidifies, rationally
Production cost is reduced, simultaneously for optimization coating process, product stability is improved and has very important significance.
The utility model is realized in this way：
A kind of coating machine automatic humidifying apparatus producing lithium battery, including humidification pipeline, rotating spraying nozzle, nozzle and wet
Spend sensor；It humidifies pipeline to be mounted on the scraper of coating machine, is located at the top of hopper；Humidify the entrance connection humidification of pipeline
Device；The lower end of humidification pipeline is provided with rotating spraying nozzle, is connected with the inside of humidification pipeline；Humidity sensor is mounted on
It humidifies on pipeline, is located at the top of hopper；Rotating spraying nozzle and humidity sensor are connect with humidifier control unit respectively.
Rotating spraying nozzle body part as described above is cylindrical, and end is taper；Rotating spraying nozzle is shared
It is multiple, every 3-10cm settings on humidification pipeline.
Multiple nozzles communicated with main body are uniformly distributed on the same circumference of the rotating spraying nozzle head conical surface as described above,
Nozzle is located at 3-10cm above slurry, and for humidifying the air above slurry, nozzle rotary circularizes air-flow in humidification,
Fog is dispersed in hopper.
As described above humidification pipeline and rotating spraying nozzle using stainless steel or copper at.
The utility model has the beneficial effects that：
It is easy to operate the utility model has the advantage of coating process humidity can be accurately controlled, it can effectively reduce coated
Production cost in journey, by keeping hopper upper air moisture stable, it is ensured that in consistency and coating process that slurry contains admittedly
The stability of coated face density.The fraction defective in coating process is greatly reduced, the consistency of coating is improved, improves battery
The stability of batch.
