DETAILED DESCRIPTION

[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 multi-point discharge extruder includes a barrel 1, a hopper 2, and a screw. The hopper 2 is fixed on the barrel 1, and a screw is rotatably connected inside the barrel 1. The discharge port of the barrel 1 is connected to a box 3, a valve 10 is installed on the box 3, a discharge nozzle 5 is provided at the bottom of the box 3, a horizontal straight rail 6 is provided below the barrel 1, a rotating mechanism 7 is slidably connected to the horizontal straight rail 6, the output shaft of the rotating mechanism 7 is fixed in a temporary storage barrel 8, a pushing mechanism 9 is installed on the temporary storage barrel 8, and the rotating mechanism 7 is installed on the horizontal moving mechanism 4.

[0018] The horizontal moving mechanism 4 includes a base 41 , a rack 42 , a gear 43 , and a motor. The motor is fixed on the base 41 , the output shaft of the motor is fixed with a gear 43 , the gear 43 is meshed with the rack 42 , and the bottom of the base 41 is fitted on the horizontal straight rail 6 .

[0019] The motor drives the gear 43 to rotate, and the rotating gear 43 moves along the rack 42, thereby driving the rotating mechanism 7 and the box body 3 to move horizontally.

[0020] The pushing mechanism 9 includes a rodless cylinder 91 and a push plate 92 . The cylinder body of the rodless cylinder 91 is fixed to the outside of the temporary storage barrel 8 . The slide seat of the rodless cylinder 91 is fixed on the push plate 92 . The push plate 92 is located in the temporary storage barrel 8 .

[0021] A weight sensor is installed on the push plate 92, and the weight sensor is electrically connected to the PLC.

[0022] The valve 10 is a solenoid valve, and the valve 10 is electrically connected to the PLC.

[0023] The rotating mechanism 7 is a rotating cylinder.

[0024] The working method of the present application is: the material is put into the hopper 2, the material in the hopper 2 enters the barrel 1, the motor drives the screw to rotate, the screw will push the material forward, and fall down through the discharge nozzle 5 of the box body 3 into the temporary storage barrel 8.

[0025] The weight sensor on the push plate 92 transmits the weight information to the PLC in real time. When the weight reaches the preset weight value, the PLC controls the motor to stop rotating the screw and starts the valve 10 to close the discharge port of the barrel 1. At this time, the horizontal moving mechanism 4 drives the temporary storage barrel 8 to move horizontally to the set position, and the rotating mechanism 7 drives the temporary storage barrel 8 to rotate so that the opening of the temporary storage barrel 8 faces downward, and then the rodless cylinder 91 drives the push plate 92 to move, and the push plate 92 pushes the material in the temporary storage barrel 8 out. Then the temporary storage barrel 8 is moved back to the bottom of the discharge nozzle 5 to prepare to receive materials again.
