[0008] As a preferred technical solution of the utility model, a first electric door is fixedly installed on the top of the medicine powder barrel, and a second electric door is fixedly installed on the left side of the medicine powder barrel.

[0009] As a preferred technical solution of the utility model, the medicine powder barrel is detachably mounted between the four first brackets by screws.

[0010] As a preferred technical solution of the present utility model, the motor is a servo motor.

[0011] As a preferred technical solution of the present utility model, the diameter of the loading funnel port is greater than the width of the second electric door.

After adopting such a structure, the automation degree of the feeder is improved, and while greatly improving the feeding efficiency of the flux-cored welding wire, it also realizes that there is no need to manually climb onto the feeding platform to feed, which reduces the risk of falling and inhaling powder during manual operation.

[0020] As a further solution of the utility model, a feeding funnel 11 is fixedly installed between the two vertical plates 2 through a second bracket 10, a filling assembly 12 is fixedly connected to the bottom end of the feeding funnel 11, and a filling area 13 is provided below the filling assembly 12. The prepared powder is filled into the U-shaped steel strip through the feeding funnel and the filling assembly for compaction, thereby producing a flux-cored welding wire.
