[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-3 As shown, a fireworks powder bead production device comprises a hopper 12, a powder bead extrusion barrel 1, a powder bead extrusion impeller 8, a main shaft 25, a main shaft sleeve 15, a cutter ring frame 11, a transmission box 28 and a frame 6; An array of extrusion holes 9 is arranged on the barrel wall of the medicine bead extrusion barrel 1, and the extrusion holes 9 are tapered holes with a large inner wall opening and a small outer wall opening. A hopper 12 is arranged above the medicine bead extrusion barrel 1, and the hopper 12 is fixed to a frame 6. A medicine bead extrusion impeller 8 is arranged in the medicine bead extrusion barrel, and the medicine bead extrusion impeller 8 has 6 blades, and the outer contour line of the horizontal projection of the blade is an involute. The medicine bead extrusion impeller 8 is fixed to the lower end of the main shaft 25, and an airway hole 22 is arranged in the center of the main shaft 25. The lower end of the main shaft has a radial jet hole 7 communicating with the airway hole 22, and the jet hole 7 has a total of 3 rows, 3 in each row, the radial direction of the central part of the medicine bead extrusion impeller is provided with air holes 33 which are communicated with all the air injection holes 7, the main shaft 25 passes through the lower bearing 16 whose outer ring is mounted in the main shaft sleeve 15, is fixed with the upper bevel gear 20, and then passes through the upper bearing 21 whose outer ring is mounted in the transmission box 28, a rotary air joint 24 is fixed to the airway hole at the upper end of the main shaft 25, the rotary air joint 24 is communicated with the outlet pipe 23 of the cooling device 18 through a pipe, and the inlet pipe 14 of the cooling device 18 is communicated with the compressed air source (not shown in the figure); The upper end of the main shaft sleeve 15 passes through the two intermediate bearings 17 of the outer ring mounted on the transmission box 28, and is fixed to the lower bevel gear 19. The upper bevel gear 20 and the lower bevel gear 19 are meshed with the left bevel gear 26. The left bevel gear 26 is fixed to the transmission shaft 29. The transmission shaft 29 passes through the two left bearings 27 of the outer ring mounted on the transmission box 28, passes through the explosion-proof wall 30, and is fixed to the output shaft of the reducer 32 with the motor 31.
