Technical field
The utility model belongs to polyimide material Preparation equipment field, and in particular to it is a kind of for polyimides production
Electric heating is adjustable die head.
Background technology
In the production of Kapton, the THICKNESS CONTROL of slab operation is more crucial.Common adjustment mode has two
Kind, adjusting slab thickness, another way is adjustment casting die head lip to a kind of local dent degree for being direct reconditioning scraper plate
The deformation extent of oral area point, so as to reach the purpose of control slab thickness.The adjustment mode of both modes is different, but adjust
Mechanism is essentially identical.The advantage of both adjustment modes is that adjustment mode is directly acted on discharging opening, the sensitivity of adjustment
Height, thickness feedback are timely.That what is in industry applied is more universal, and the equipment of correlation, frock are more complete.But both adjustment
The shortcoming of mode is also obvious.
The method of adjustment of reconditioning scraper plate is a kind of destructive adjustment, as the increase of number of times can cause scraper plate to be scrapped.In addition
