  • Patent number: 9650162
    Abstract: The invention relates to a device for metering bulk material, in particular plastics granulate, for machines processing plastics granulate, in particular for injection molding machines, wherein at least one material funnel (2) into which bulk material can be filled and which has a material valve is provided. A weighing container (4) connected to weighing scales is optionally arranged below the material valve. A control unit is provided for the weighing scales and material valves. The material valve is designed as a metering valve (3), in particular as a flap-type metering valve. The metering valve (3) consists of a part, a closure (7), movable via a horizontal axis (6) and a fixed part, a scraper (8). The movable part has an operating arm (9) for an actuator (5) and at the end facing towards the fixed part has a closure plate (10) having a scraper projection (11). In the closed state of the metering valve (3) the scraper projection (11) touches the scraper (8).
