[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] The embodiment of the present application discloses a feeding device for a powder packaging machine, comprising a hopper 1, a discharge port at the bottom of the hopper 1 fixedly connected to a feed pipe 2, a feeding mechanism provided inside the feed pipe 2, the other side of the feed pipe 2 being inclined upward, and the upper end of the feed pipe 2 being fixedly connected to a discharge pipe 4 pointing vertically downward, a metering tube 7 being sleeved on the outer surface of the lower end of the discharge pipe 4, a weighing mechanism being provided between the metering tube 7 and the discharge pipe 4, an electromagnetic valve 12 being provided inside the discharge port of the metering tube 7, and when the weighing mechanism reaches a set value, the electromagnetic valve 12 is opened so that the powder can be quantitatively conveyed.

[0018] Furthermore, the feeding mechanism includes a rotating shaft 5 rotatably installed at the inner center of the feeding pipe 2, a dragon blade 6 is fixedly connected to the surface of the rotating shaft 5, a motor 3 is fixedly installed at the bottom of the feeding pipe 2, and the output shaft of the motor 3 is fixedly connected to the rotating shaft 5.

[0019] Furthermore, a frame is provided on the surface of the hopper 1 and the conveying pipe 2 , and the frame is used to support the hopper 1 and the conveying pipe 2 .

[0020] In this embodiment, the motor 3 drives the rotating shaft 5 and the dragon blade 6 to rotate, so that the powder in the hopper 1 can be transported to the upper end of the feeding pipe 2, so that the powder at a low place can be transported to a high place to meet production needs; in addition, by setting a weighing mechanism in conjunction with the metering tube 7, when the weight of the powder in the metering tube 7 reaches a set value, the weighing mechanism triggers the solenoid valve 12 to open, thereby realizing quantitative feeding.

[0021] Furthermore, the diameter of the metering tube 7 is larger than that of the discharge tube 4, the upper end opening of the metering tube 7 is adapted to the outer diameter of the discharge tube 4, the lower end of the discharge tube 4 is installed inside the metering tube 7 through the opening and slides with it, and the structure of the discharge tube 4 inside the metering tube 7 is set to an inverted T shape.

[0022] Furthermore, the weighing mechanism includes a spring 8 sleeved on the outer surface of the discharge pipe 4, the lower end of the spring 8 is fixedly connected to the end of the discharge pipe 4, the upper end of the spring 8 is fixedly connected to the inner upper surface of the metering tube 7, and the surface of the discharge pipe 4 is sleeved with an annular plate 11, which is located above the metering tube 7. An electric push rod 9 is fixedly connected to the upper surface of the metering tube 7, and the electric push rod 9 is arranged upright, and the telescopic end of the electric push rod 9 is fixedly connected to the annular plate 11.

When the annular plate 11 contacts the touch switch 10, the solenoid valve 12 is opened.

[0023] In this embodiment, when the metering tube 7 is filled with powder, the weight of the powder and the metering tube 7 causes the metering tube 7 to move downward along the discharge pipe 4, causing the electric push rod 9 and the annular plate 11 to move downward. When the annular plate 11 contacts the touch switch 10, the solenoid valve 12 is opened, and the powder inside the metering tube 7 can be discharged from its lower outlet. Furthermore, when the metering tube 7 is unloaded, the electric push rod 9 is used to adjust the distance between the annular plate 11 and the touch switch 10, thereby controlling the downward movement distance of the metering tube 7 and, therefore, the load on the metering tube 7.

[0024] It should be noted that the solenoid valve 12 is used to control the on / off state of the lower end of the metering tube 7. A corresponding battery assembly can be set on the surface of the metering tube 7 or other parts to provide power for the solenoid valve 12.
