Description
Affiliated technical field
The present invention relates to a kind of plastics machinery, especially a kind of film biaxial orientation stretching machine.
Technical background
Kapton is a kind of novel high temperature resistant organic polymer thin film, is to be formed through imidization through polycondensation and hydrostomia film forming in extremely strong property solvent dimethylacetylamide by pyromellitic acid anhydride and diaminodiphenyl ether again.It is the present best film class insulating materials of performance in the world, has excellent mechanical property, electrical property, chemical stability and very high radiation resistance, high temperature resistant and resistance to low temperature-269 ℃ to+400 ℃.Nineteen fifty-nine, du pont company at first synthesized aromatic polyimide, manufactured experimently into Kapton (PI film) in 1962, and nineteen sixty-five begins to produce, and trade names are KAPTON.China end of the sixties can the small lot batch manufacture Kapton, the main product one-way membrane.The biaxial stretching film of domestic production in recent years has been widely used in every field such as aviation, navigation, spaceship, rocket-powered missile, atomic energy, electronic apparatus industry now.
Kapton is a kind of high temperature resistant organic polymer thin film, is the basic material of F, H class B insulation, and this film has favorable mechanical performance, electrical insulation properties, chemical stability and radiation resistance.Because its purposes of its good comprehensive performances also enlarges gradually; Aviation, navigation have been widely used at present; But because polyamides comes the production equipment requirement condition of amine biaxially oriented film high; Need to continue heating; General biaxial orientation stretching machine can't be produced; And power consumption is high, and valuable product does not satisfy the demand of domestic market.
Summary of the invention
The objective of the invention is to avoid the deficiency of prior art and a kind of Kapton biaxial orientation stretching machine is provided.
The technical scheme that the present invention adopted is: a kind of Kapton biaxial orientation stretching machine; Comprise needle plate formula link chain mechanism; Stretching-machine casing, vertical chain and transmission mechanism, automatic expanding mechanism, automated closed-loop heating system, internal-circulation type bellows; It is characterized in that the stretching-machine casing is a double-layer stainless steel, middle filled high-temperature heat-barrier material; Vertical chain and transmission mechanism are made up of main driving motor, belt pulley, main shaft, feather key, sprocket wheel; Main driving motor is connected with spindle on being installed in wallboard through belt pulley; Be connected with sprocket wheel through feather key; The sprocket wheel rotation drives vertical chain advances, and the Kapton that drives then on the vertical chain is made horizontal motion; Automatically expanding mechanism is made up of reducing motor, minor sprocket, amplitude modulation leading screw, nut, slide; Reducing motor drives the minor sprocket rotation; Act on nut through the amplitude modulation leading screw; Driving slide slides on main shaft; Do two-way expanding motion; Displacement transducer is fixed on the amplitude modulation leading screw, and is connected with the host computer of automated system; Electric heating system is made up of embedded electric heater, temperature sensor, temperature controller, host computer; Embedded electric heater is fixed in the casing; The top is provided with the internal-circulation type bellows; Temperature sensor is fixed in the casing; Host computer connects temperature sensor, and controls embedded electric heater through temperature controller.
Compared with prior art; Advantage of the present invention is: symphysis is continuous to be hung on the needle plate equably; Film is stressed evenly during stretching; Consistency of thickness; Product quality has obtained further raising; The effective width that embedded electric heater has improved the efficiency of heating surface and effectively dwindled the stretching-machine body; Make the thermosetting of the Kapton of production meet the technological requirement of this product more; Temperature in the casing is more even, has dwindled the space of the thermal treatment zone, when identical production temperature, has reduced heating power to greatest extent; Saved the utilization of electric energy; The temperature of each thermal treatment zone is balance more, has reduced toxic emission, more environmental protection.
