The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Examples are given.

See fig. 1-3.

The embodiment of the invention discloses a metering device of a raw material weighing and mixing machine, which comprises a rack 1, a stirring chamber 2, three hoppers 3, a scale pan 5, three screw feeders 4 and a control box 10.

In this embodiment, three hoppers 3 are installed on the top of the frame 1 and can be used for containing three different materials. The stirring chamber 2 is arranged in the middle of the frame 1 and is used for stirring and mixing three different materials. Balance 5 and three screw feeder 4 are all installed in frame 1, weighing sensor 6 is installed to balance 5, every screw feeder 4 all disposes a step motor 7, drive by step motor 7, a screw feeder 4 corresponds a hopper 3, screw feeder 4 is arranged in sending the material in hopper 3 to balance 5, balance 5 has the discharge gate, balance 5's discharge gate is located 2 tops of teeter chamber, discharge gate department is provided with an swash plate 8, material in the balance 5 slides to teeter chamber 2 through swash plate 8, be connected with ejection of compact funnel 9 below teeter chamber 2.

In this embodiment, the control box 10 is installed on the frame 1, the stepping motor 7 and the weighing sensor 6 are both in communication connection with the control box 10, and the control box 10 is used for controlling the operation of the device

In the actual operation process, when this device uses, for example when measuring the ratio of three kinds of materials of a raw materials, look female and additive, carry three kinds of different materials automatically in three hopper 3 earlier, then according to three kinds of material proportions of settlement respectively through the weight of the material of the screw feeder 4 that hopper 3 corresponds respectively to balance 5, because screw feeder 4 has adopted step motor to drive, according to real-time unloading weight adjustment motor speed, form closed-loop control, reach the purpose of accurate control each kind of material weight, three kinds of materials are after balance 5 scales, put stirring chamber 2 and carry out even stirring, the material that the stirring is even is provided for injection molding machine or extruder and is used.
