Description of drawings
Fig. 1 is the structural representation of high-performance low thermal expansion coefficient polyimide film biaxial tension described in the utility model system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
High-performance low thermal expansion coefficient polyimide film biaxial tension described in the utility model system, as shown in Figure 1, the opposed needle plate 1 that comprises the transverse ends portion that is used for fixing Kapton, described needle plate 1 is driven by driving its drive unit of doing lengthwise movement, and then can drive Kapton do lengthwise movement in the biaxial tension system.Described biaxial tension system comprises that also at least one regulates the adjusting device of the aperture of opposed needle plate 1 (Reference numeral among Fig. 1 is 3 to 9).By the adjusting of this adjusting device, can change the relative distance of opposed needle plate 1, and then make in the vertical traveling process of Kapton and obtain cross directional stretch, to change the horizontal mechanical performance of Kapton.The purpose that a plurality of adjusting devices are set is and can the cross directional stretch degree of Kapton be regulated at any time according to the draw ratio requirement of different phase, different proportion.
As shown in Figure 1, the adjusting device in the biaxial tension described in the utility model system can comprise first nut 21, second nut 22, leading screw 23, turning handle 24.Wherein, described first nut 21 is connected with the needle plate of a side wherein, described second nut 22 is connected with the needle plate of aforementioned needle plate opposite side, and described leading screw 23 with relative threaded portion passes first nut 21, second nut 22, is provided with turning handle 24 in the end of this leading screw 23.When turning handle 24 rotates, can drive leading screw 23 simultaneously rotates, because the screw thread on this leading screw 23 is a relative direction, so the rotation of leading screw 23 will make first nut 21, second nut 23 move in opposite directions or dorsad, the opposed needle plate 1 of final drive moves in opposite directions or dorsad, to reach the effect to the Kapton cross directional stretch.Film after the imidization is taken off film by the stripper apparatus of special use from geometrical clamp, enter subsequent handlings such as side cut, rolling.
Drive unit in the biaxial tension described in the utility model system can specifically comprise opposed chain and with the opposed head sprocket 10,11 of described chain engages, described opposed head sprocket 10,11 is by motor 12 Driven by Coaxial, and promptly motor 12 drive head sprockets 10,11 rotate synchronously.Wherein, described motor 12 preferred variable-frequency motors.
In the utility model, described drive unit also can further comprise opposed from sprocket wheel 17,20,13,14, is provided with can realize the operation of chain the drive unit is led from sprocket wheel.Described preferred arrangement from sprocket wheel is the middle part that is arranged on chain.
