NOVELTY - The utility model claims a graphene film and carbon fibre prepreg filtering device, comprising a bottom plate, a filter main body, a collecting groove; the upper surface of the bottom plate is fixedly connected with four first brackets; the top end of the first bracket is fixedly connected with the same filter main body; the beneficial effects of the utility model are as follows: connecting the external power supply; the motor drives the rotating wheel to rotate; the rotating wheel drives the lug of the edge to rotate; driving one end of the crank arm to do circular motion; the other end of the crank arm drives the piston to do reciprocating motion; when the piston moves upwards, the inner pressure of the filter main body is reduced; the baffle close to the discharging port is closed; the baffle close to the feeding port is opened; absorbing epoxy resin; when the piston moves downwards, closing the baffle close to the feeding port; the epoxy resin passes through the filter screen under the action of the pressure; the piston can drive the supporting rod to move downwards; the supporting rod drives the scraper to move downwards; the scraper scraping the impurity on the surface of the filter screen into the collecting groove; it is not easy to be blocked; the filtering efficiency is higher.
