Abstract

The invention discloses a hot air circulating system for an air knife of a two-way stretching membrane for extruding and casting. The hot air circulating system is an integral system including a high-pressure centrifugal ventilator with variable frequency control, a gas filter, a conveying air duct, a gas heater, the air knife, a hot oil temperature control station and a hot air temperature pressure control unit, wherein the high-pressure centrifugal ventilator with variable frequency control is connected with the gas filter; the gas filter is connected with one end of a hot air jacket of the gas heater through a connection pipe, and the other end of the gas heater is connected with the air knife through the conveying air duct. According to the hot air circulating system disclosed by the invention, an air source is clean gas with adjustable temperature, and the air blown from the air knife is hot air with controllable temperature and pressure. Due to the action of the air knife, besides that the membrane can be better attached to a cold roll so as to reduce the pinch phenomenon at two ends of a casting film, the cooling speed of a flux and the temperature of the membrane can also be controlled; the crystal types and the crystallinity required by a user are ensured, and advantages are provided for the next stretching orientation, an intergranular structure and other special requirements.

Description

technical field [0001] The invention relates to an air knife hot air circulation system for extruding salivating biaxially stretched diaphragms. Background technique [0002] At present, the air knife hot air circulation system for extruding salivating biaxially stretched diaphragms is still blank in China, and there is no technology in this area. Contents of the invention [0003] The object of the present invention is to provide an air knife hot air circulation system for extrusion drool biaxial stretching diaphragm. [0004] The technical scheme adopted by the present invention to achieve the above purpose is: extruding salivating bidirectional stretching diaphragm air knife hot air circulation system, including high-pressure centrifugal fan (1) controlled by frequency conversion, gas filter (2), conveying air pipe (3 ), gas heater (4), air knife (5), hot oil temperature control station (6) and hot air temperature and pressure control unit (7), the frequency conversion...
