2.2 air knife coater (one set)

   Air knife coater is mainly composed by the eagle beak knife, feeding roll, pressing roll, metering rod, backing roll, air separator, draft fan for separator, high pressure fan and frame etc.
This coating device is characterized by a short distance between the air knife backing roll and the feeding roll, and the coated paper is less water migrated and wrinkled after the metering rod. It has the advantages of compact structure, wide application range, convenience to adjust the coating weight and so on.
Air knife (eagle beak type)
      Composed by the up and bottom lip plates, air knife body, air distribution tube. Up and bottom lips made of the 304 stainless steel, though multiple precision processing. The shape of the air knife blade can make high-speed air flow along the breast roll tangent direction, with merit of good quality coating, less spray and so on.
Air knife adjustment
Knife gap can be adjusted between 0.3-1.0mm. The air gap between the knife and the backing roll and angle can be adjusted by adjusting the frame, and air pressure can be adjusted to control the coating weight.
Air knife backing roll
      During the coating process, the paper with excess coating color wrapping around the backing roll, and the roll surface becomes the supporting surface for the paper to bear the airflow. The cooperation between the air flow and the air knife is used to meter the coating amount. Air knife backing roller Φ270mmx1400mm, bearing SN509, roll body is seamless steel pipe, surface hard chrome plated.
The feeding roll
Φ216mmx1400, bearing P208, the roll made of seamless steel pipe, hard chrome plated treatment, with single drive of three-phase asynchronous motor.
Metering rod
      Metering rod device mainly plays the role of the pre-metering of coating amount, by scrap exceed color on the paper to reduce the air knife metering burden, and reduce the color splash. Metering rod diameter Φ20mm, chrome plated ,with drive motor.
Color tray
      Paint tray made of stainless steel 304, thickness 1.5mm, there are two trays, feeding roll tray and backing roll tray, respectively for storage and recovery of coating color.
Air separator device
    Due to high speed and high wind pressure, in order to prevent the coating splash phenomenon, design the color splash recovery device. The power of the air separating fan is 3Kw.
High-pressure fan
     Select special series of energy-saving coating fan, fan power 15Kw. The fan is characterized by high wind pressure, low noise, wind pressure stable.
The frame
Box-type structure, welded, the coater is separated.
2.3 Hot air drying system
