[0026] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.
[0027] like Figure 1-10 A filling device capable of preventing powder products from raising dust comprises a hopper structure 1, a powder screening structure 2, a material transfer structure 3 and a material receiving structure 4 which are arranged in sequence from top to bottom, wherein a powder screening cavity 20 extending in a vertical direction is formed in the powder screening structure 2, wherein a feeding end of the powder screening cavity 20 is communicated with the hopper structure 1, and a discharging end of the powder screening cavity 20 is communicated with the material transfer structure 3, wherein the material transfer structure 3 comprises a turntable 31 and a barrel 32 arranged on the turntable 31, wherein the barrel 32 has an opening, and when the turntable 31 drives the barrel 32 to rotate until the opening faces upward, the barrel 32 can receive the powder in the powder screening cavity 20 through the opening; when the turntable 31 drives the barrel 32 to rotate until the opening faces downward, the barrel 32 can load the powder into the material receiving structure 4 through the opening.
[0028] The utility model proposes a filling device capable of preventing powder products from raising dust. Powder is added to the hopper structure 1, and the powder enters the powder screening structure 2 from the hopper structure 1. Since the powder screening structure 2 has a powder screening cavity 20 extending in the vertical direction, the powder is in the powder screening cavity 20, and under the action of gravity, the heavier powder first falls to the bottom of the powder screening cavity 20. When the powder sinks into the powder screening cavity 20, the lighter powder is at the upper end and the heavier powder is at the lower end. The material transfer structure 3 is between the powder screening structure 2 and the material receiving structure 4. When the turntable 31 rotates until the opening of the barrel 32 faces upward and toward the hopper structure 1, the powder in the powder screening cavity 20 enters the barrel. 32, at this time, the lighter powder in the barrel 32 is at the upper end and the heavier powder is at the lower end. When the turntable 31 rotates, the barrel 32 is driven to rotate. When the opening of the barrel 32 is rotated to face downward and toward the receiving structure 4, the lighter powder is at the lower end and the heavier powder is at the upper end. At this time, the powder in the barrel 32 is loaded into the receiving structure 4, and the lighter powder enters the receiving structure 4 first. The heavy particles in the powder are used to cover the light particles, which has a dust-proof effect, can effectively avoid the dust generated by the powder, can effectively avoid the raised dust adhering to the inner side of the receiving structure 4, resulting in poor product sealing, and reduce the loss of fine particles in the powder.
