A fixed plate 20 is fixedly arranged in the discharge pipe 15, and an electric push rod 21 is fixedly arranged on the top of the fixed plate 20. The output end of the electric push rod 21 is fixedly connected with the top wall of the sealing cylinder 14. When discharge is needed, the electric push rod 21 is elongated to push the sealing cylinder 14 upward, thereby opening the discharge ports 16. When discharge is not needed, the electric push rod 21 is shortened to drive the sealing cylinder 14 to move downward, thereby sealing the discharge ports 16.

[0034] In order to spray powder into the cylinder body 2, a spray pipe 11 is arranged. The spray pipe 11 is slidably arranged on one side of the cylinder body 2, and one end of the spray pipe 11 is connected with an external powder pump through a connecting pipe 10. An extension rod 12 is fixedly arranged on the outer wall of the spray pipe 11 and located in the conical cylinder 18. When the conical cylinder 18 rotates, the extension rod 12 stirs the materials to ensure that the powder is uniformly coated on the materials. The extension rod 12 is a common spring extension rod.

[0035] In order to seal the top end of the barrel 2, the cover plate 6 is arranged. The cover plate 6 is rotatably arranged on the top of the workbench 1, and the bottom end is attached to the top of the barrel 2.
