DETAILED DESCRIPTION

[0026] The specific implementation of the utility model will be further described in detail below with reference to the accompanying drawings.

[0027] An additive powder mixing structure under this specific implementation method, such as Figure 1-5 As shown, it includes a mixing barrel 1, powder is placed inside the mixing barrel 1, a mixing mechanism 2 is arranged inside the mixing barrel 1, and the mixing mechanism 2 rotates to mix the powder, the mixing barrel 1 includes a straight barrel 101, the bottom of the straight barrel 101 is connected to a conical barrel 102, a feed port 103 is arranged above the side of the straight barrel 101 for adding raw materials or additives, a guide member 104 is arranged at the junction of the straight barrel 101 and the conical barrel 102, a connecting rod 105 is fixedly connected to the outer surface of the guide member 104, the end of the connecting rod 105 is fixedly connected to the inner wall of the straight barrel 101, and a channel is left between the inside of the straight barrel 101 and the outer surface of the guide member 104;

[0028] The mixing mechanism 2 includes a power unit 201 installed on the top of the straight cylinder 101. The power unit 201 is driven by a transmission rod 202. The transmission rod 202 extends into the interior of the straight cylinder 101. A mixing blade 203 is installed on the outer surface of the transmission rod 202. The mixing blade 203 rotates to stir and mix the powder.

[0029] The bottom axis of the conical barrel 102 is connected to an auxiliary structure 3, and the auxiliary structure 3 includes a discharge pipe 301. The side of the discharge pipe 301 is connected to an air inlet pipe 302 to connect to the high-pressure gas. A sealing valve is provided at the bottom of the discharge pipe 301 to seal the bottom of the discharge pipe 301. When discharging, the discharge pipe 301 is used for discharging. When inflating, the discharge pipe 301 is sealed through the sealing valve, so that the airflow passes through the discharge pipe 301 and enters the interior of the straight cylinder 101 to blow the powder.

[0030] According to the above technical solution, a transmission rod 202 is arranged inside the straight cylinder 101 to drive the mixing blades 203 to rotate and stir the powder, and a discharge pipe 301 is arranged at the bottom of the conical barrel 102, and an air inlet pipe 302 is arranged on the side of the discharge pipe 301 to connect with the high-pressure gas. During the mixing process, high-pressure gas is filled from the air inlet pipe 302, and the gas impacts the powder through the gap between the straight cylinder 101 and the guide member 104, so that the powder floats inside the straight cylinder 101, avoiding powder accumulation, thereby achieving the effect of improving the powder mixing efficiency.

[0031] During use, the total amount of raw material powder and additive powder inside the straight cylinder 101 should not exceed half of the internal volume of the straight cylinder 101 to provide space for the powder to float.

[0032] Specifically, the guide member 104 is gyro-shaped, and a bearing seat is provided at the axis of the top of the connecting rod 105 to support and limit the bottom of the transmission rod 202 to improve the rotation stability of the transmission rod 202. There is a gap between the bottom of the guide member 104 and the inner bottom of the conical barrel 102.

[0033] Through the above technical solution, the guide member 104 is set as a gyroscope, the purpose of which is to facilitate the discharge of powder and change the wind direction. When the high-pressure gas passes through the outer surface of the guide member 104, it is changed by the curved surface of the guide member 104, which can make the powder float better than the straight air flow.

[0034] Furthermore, the top of the guide member 104 is conical, which can effectively prevent powder from accumulating on the top of the guide member 104 and facilitate mixing and unloading.

[0035] Specifically, the connecting rods 105 are round rods or straight rods with a ring-shaped top, and the connecting rods 105 are radially and equidistantly distributed.

[0036] Through the above technical solution, the connecting rod 105 is set to a round rod or a straight rod with a ring portion, and the purpose is the same, which is to prevent powder from accumulating on the top of the connecting rod 105. The radially distributed connecting rods 105 can stably support the guide member 104, and there are large gaps between the connecting rods 105 for airflow to pass through.

[0037] Specifically, the mixing blade 203 is a threaded metal strip, and a support rod 204 is provided at the connection between the mixing blade 203 and the transmission rod 202 .

[0038] Through the above technical solution, the mixing blades 203 are set as threaded metal strips, so that when mixing powders, the mixing range can be increased, and the mixing blades 203 can generate upward lift while rotating to drive the powder upward, thereby improving the efficiency of powder mixing.

[0039] Specifically, the mixing blades 203 are two or more thread-shaped metal strips, and the two or more thread-shaped metal strips are staggered and surround the periphery of the transmission rod 202 .

[0040] Through the above technical solution, the purpose of providing multiple mixing blades 203 is to further improve the mixing range and the efficiency of driving the powder to rise.

[0041] Specifically, the outer surface of the mixing blade 203 is close to the inner wall of the straight cylinder 101, and the edge of the mixing blade 203 is a sharp edge.

[0042] Through the above technical solution, the outer surface of the mixing blade 203 is brought closer to the inside of the straight cylinder 101, thereby increasing the stirring ability of the mixing blade 203 and avoiding the gap between the mixing blade 203 and the inside of the straight cylinder 101 being too large to reduce the mixing effect.

[0043] Specifically, a ventilation hole is provided at the top of the straight tube 101, and a filter is provided inside the ventilation hole.

[0044] Through the above technical solution, the purpose of setting the ventilation holes at the bottom of the straight cylinder 101 is to improve the fluidity of the gas, and the function of setting the filter is to prevent the powder from being blown out through the ventilation holes.

[0045] When in use, a transmission rod 202 is arranged inside the straight barrel 101 to drive the mixing blades 203 to rotate and stir the powder, and a discharge pipe 301 is arranged at the bottom of the conical barrel 102, and an air inlet pipe 302 is arranged on the side of the discharge pipe 301 to connect with the high-pressure gas. During the mixing process, high-pressure gas is filled from the air inlet pipe 302, and the gas impacts the powder through the gap between the straight barrel 101 and the guide member 104, so that the powder floats inside the straight barrel 101, avoiding powder accumulation, thereby achieving the effect of improving the powder mixing efficiency;

[0046] By setting two mixing blades 203 and setting the mixing blades 203 as threaded metal strips, the mixing blades 203 can increase the stirring range during stirring, and the edges of the mixing blades 203 are set as sharp edges, so that during the stirring and mixing process, the agglomerated powder can be broken up, thereby achieving the effect of increasing the stirring range and reducing powder agglomeration.

[0047] It should be noted that although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these specific embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
