Wherein, the zone of heating of described drying baker preferably comprises some uniform hot water radiation wires, for as the homogeneous heating source in drying baker.
Wherein, the soaking plate of described drying baker is evenly equipped with some through holes, advantageously in the transmission of heat.Preferably, described soaking plate is made of metal, and is more preferably copper or iron.
Wherein, described extruder is connected with fluid reservoir, premixed liquid for shaping Kapton is stored in described fluid reservoir, and is transported to extruder by fluid reservoir, and described extruder makes premixed liquid with predetermined thickness by the flow casting molding on the surface of the base band below it.
Wherein, described let off roll is used for the base band volume being ready to use in film forming unreel and draw; Described wind-up roll be used for by Kapton dry and through or without other process be separated with base band after, by be separated after base band rolling; Described wind-up roll is also connected with driving mechanism, and described driving mechanism rotates for driving described wind-up roll, and provides the active force of advance for the transmission of base band on described casting machine.
Further, the front of described extruder is also provided with bellows, for the base band surface of clean film to be formed, and the air outlet of described bellows and the vertical by direction of described base band; Preferably, the air-out direction of described bellows and described base band are 120 ° of-150 ° of angles by direction.
Further, after direction being positioned at described drying baker, be also provided with some symmetrically arranged air blasts along base band, for clean surface for the treatment of the form film of rolling; Preferably, the air-out direction of described air blast and described base band are 30 °-45° angle by direction.
Advantage of the present utility model is: (1), by the particular design of hot gas fluid layer in drying baker, makes heating source and thermal current two kinds of mode of heatings effectively be combined, and is more conducive to stability and the validity of heating; (2) hot gas fluid layer makes heat be uniformly distributed in drying baker by soaking plate and bending roundabout passage, is conducive to the even oven dry of film; (3) by the setting of bellows and air blast, the defect caused because of impurity such as dust falls in flow casting molding process is also avoided.
