[0015] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0016] Figure 1 It is a structural schematic diagram of the utility model.

[0017] As attached Figure 1 As shown, a precise material control extruder comprises a hopper 1, a barrel 2 and a screw 3. The hopper 1 is mounted on the barrel 2, and the screw 3 is rotatably connected in the barrel 2. The discharge port of the barrel 2 is connected to the inlet of a gear discharge mechanism 5 through a hose 4. The gear discharge mechanism 5 is fixed on the output shaft of a rotating mechanism 6. The body of the rotating mechanism 6 is fixed on a lifting mechanism 7. A horizontal conveying platform 8 is provided below the gear discharge mechanism 5, and a carrier 9 is provided on the horizontal conveying platform 8.

[0018] The gear discharging mechanism 5 includes a box body 51, a gear 52, a discharging pipe 53, and a motor. The motor is fixed in the box body 51. Two mutually meshing gears 52 are rotatably connected in the box body 51. The discharging pipe 53 is connected to the discharging port at the bottom of the box body 51. The feeding port at the top of the box body 51 is connected to the hose 4. The output shaft of the motor is connected to a gear 52.

[0019] The rotating mechanism 6 is a servo motor.

[0020] The lifting mechanism 7 is a power cylinder, and the piston rod of the power cylinder is fixed on the body of the rotating mechanism 6.

[0021] The horizontal conveying platform 8 is a belt conveyor.

[0022] A weight sensor is installed in the carrier 9, and the weight sensor is electrically connected to the PLC.

[0023] The working method of the present application is as follows: the empty container is placed in the carrier 9, and the horizontal conveyor 8 conveys the carrier 9 and the empty container horizontally to the bottom of the discharge pipe 53. The material is placed in the hopper 1, and the motor drives the screw 3 to rotate, and the screw 3 pushes the material in the barrel 2 forward and enters the box 51 through the hose 4. The motor drives the two gears 52 to rotate, and the material falls down between the two gears 52. When the gear 52 stops rotating, the material cannot fall, so the output of the material can be accurately controlled by controlling the rotation of the gear 52. The output material falls into the empty container, and at this time the weight sensor will transmit the weight information of the carrier 9 to the PLC, and the PLC will determine whether the weight of the material in the container is accurate.

[0024] The lifting mechanism 7 can control the height of the gear discharging mechanism 5, and the rotating mechanism 6 can control the discharging angle of the gear discharging mechanism 5, so as to adapt to containers of different heights and positions.

[0025] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
