Precise extrusion and transfer apparatus for light guide plate production

Abstract

The present invention discloses a precise extrusion and transfer apparatus for light guide plate production, including: a feed hopper; a dehumidifying and drying device; a screw conveyor fixedly mounted on one side of the outer wall of the dehumidifying and drying device; a screw extrusion device; and a molding box fixedly mounted with first motors and a second motor on one side of the outer wall by means of bolts, where power output ends of two sets of first motors pass through the molding box and are fixedly mounted with first precise roller bearings by means of rotating shafts, and a power output end of the second motor passes through the molding box and is fixedly mounted with a second precise roller bearing by means of a rotating shaft. According to the present invention, one-step molding from a particle base material to a finished light guide film is implemented, the problem of warpage is overcome, the production efficiency is improved, and the production cycle can be shortened to 1 s; and the product is thinner and can be as thin as 80 μm, the production costs such as material consumption and labor are greatly reduced, key indicators of the product such as brightness and light transmittance of the light guide film are comprehensively improved, and the advantages in quality and costs are enabled in fierce market competition.
