[0021] The inner diameter of the sleeve 42 is larger than the outer diameter of the pressure rod 31, and a gap of 0.1mm-0.5mm is set between the inner diameter of the sleeve 42 and the outer diameter of the pressure rod 31, which effectively reduces the gap between the pressure rod 31 and the sleeve 42 without affecting the sliding of the pressure rod 31 in the center of the sleeve 42, thereby reducing the possibility of solder powder stagnation between the pressure rod 31 and the sleeve 42.

[0022] The transmission wheel 33 is a gear, and the transmission wheel 33 is movably connected to the center of the gear box 3. The upper end of the pressure rod 31 passes through the sleeve 42 and is respectively meshed with the rack 32 and connected to the two sides of the transmission wheel 33. The lower end of the pressure rod 31 is located above the connection between the material receiving tube 41 and the sleeve 42, and the length of the pressure rod 31 is greater than the length of the sleeve 42. The transmission wheel 33 is driven to rotate by the lifting of the rack 32, and then the pressure rod 31 is driven to lift and move by the rotation of the transmission wheel 33, so that the pressure rod 31 presses the solder powder bottle 71 located below the sleeve 42 through the sleeve 42, so as to compact the solder powder in the solder powder bottle 71 and increase the content of solder powder filled in the solder powder bottle 71.

Then, the solder powder in the barrel 15 is dropped into the tipping bucket inside the feeding rack 1 through the feeding hole 13 in sequence. The solder powder inside the tipping bucket is transported and dumped into the hopper 11 through the conveyor belt inside the feeding rack 1. The hopper 11 is connected to the receiving pipe 41 in the material distribution structure 4 through the guide pipe 12, so that the solder powder in the hopper 11 is sent into the sleeve 42 through the guide pipe 12 and the receiving pipe 41, and is transported to the solder powder bottle 71 placed below through the sleeve 42. Since the solder powder is in a fluffy state when it initially enters the solder powder bottle 71, As a result, the welding powder cannot be fully introduced into the welding powder bottle 71, the rack 32 in the gear box 3 is driven to rise and fall by the pressure cylinder 6, and the transmission wheel 33 inside the gear box 3 is respectively meshed and connected with the rack 32 and the pressure rod 31, so that the lifting and lowering of the rack 32 drives the transmission wheel 33 to rotate, and the rotation of the transmission wheel 33 drives the pressure rod 31 to rise and fall and press inside the sleeve 42, so that the pressure rod 31 passes through the sleeve 42 to compact the welding powder in the welding powder bottle 71, and at the same time, the welding powder inside the sleeve 42 is also fully pressed into the welding powder bottle 71, so as to improve the sufficiency of the welding powder in the welding powder bottle 71 after filling; after the welding powder in the welding powder bottle 71 is filled, the push cylinder 5 drives the shifting block 51 to push the welding powder bottle 71 into the conveyor belt 7 for transmission out.
