Abstract
The present invention discloses an LCP film production apparatus and method. The apparatus includes: a rack; a screw extrusion device; a T-shaped material port; a squeezing assembly, where the squeezing assembly includes a first roller wheel, a second roller wheel, and a third roller wheel, the first roller wheel and the second roller wheel are fixedly mounted directly below the T-shaped material port side by side, and the third roller wheel is fixedly mounted next to the second roller wheel side by side; and an electromagnetic field generator, fixedly connected to the T-shaped material port and mounted around the T-shaped material port in a circle by means of bolts, where the screw extrusion device is fixedly mounted at the top of the rack, and the T-shaped material port is fixedly mounted on one end of the screw extrusion device. According to the present invention, a field generated by the electromagnetic field generator can disrupt the ordered arrangement of LCP molecules, thereby alleviating or even eliminating the anisotropic problem of transverse and longitudinal tensile strength thereof.
