Abstract

This invention discloses a clamping jaw type metering device. The metering device comprises a discharging hose and a clamping mechanism used for tightly clamping the discharging hose, wherein the clamping mechanism comprises a base and a clamping piece arranged on the base, the clamping piece comprises a forward and reverse lead screw, a motor, a bearing installing plate, sliders, and guiding rods, the motor and the bearing installing plate are arranged at the two ends of the forward and reverse lead screw respectively, the sliders are located between the motor and the bearing installing plate and symmetrically arranged on the two sides of the forward and reverse lead screw, the sliders can move relative to each other along the forward and reverse lead screw, the guiding rods are arranged on the base, used for balancing movement of the sliders and parallel with the forward and reverse lead screw through a support fixed to the base, the sliders and the guiding rods are connected in a sliding mode, and one end of each slider is provided with upper-row clamping jaws stretching out in the direction of the hose. The clamping jaw type metering device is simple in structure, small in size and flexible and convenient to operate; materials supplied by the device can be either powder or particles, the metering device is totally sealed, no dust exists, friction caused by spiral metering is also avoided, and materials are not damaged.

Description

technical field [0001] The invention relates to the technical field of metering, in particular to a claw-type metering device. Background technique [0002] At present, the main measurement methods of packaging machinery include screw measurement, electronic scale measurement, etc. A screw conveyor is a common material conveying device. It usually includes a feeding pipe and a rotating shaft located in the feeding pipe. Helical blades are distributed around the rotating shaft. The rotating shaft can be connected to the drive motor through a transmission mechanism such as a belt, gear or chain. In the polymer material product industry, the conveying machinery that uses the continuous rotation of the spiral blade to push the material is mainly used to convey powdery and granular bulk materials such as carbon black, calcium carbonate, stearic acid, zinc oxide, and sulfur powder. The existing screw metering devices are all designed with three motors, which respectively driv...
