[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1, as Figure 1-5 As shown, a stirring blade structure for a powder gas conveying mixer includes a driving shaft 1, a clamping slot 11, a mounting member 12, a mounting portion 3 and a stirring portion 2 arranged in the powder gas conveying mixer; the driving shaft 1 is connected to the powder gas conveying mixer through the mounting member 12. When in use, the driving shaft 1 is threadedly fixed to the inside of the powder gas conveying mixer through the mounting member 12 to help connect the driving shaft 1 and the output end of the motor on the powder gas conveying mixer. When in use, the motor on the powder gas conveying mixer will be connected to an external power supply to drive the driving shaft 1 to rotate, prompting the stirring portion 2 to rotate accordingly, so as to perform stirring operations on the inside of the powder gas conveying mixer.

[0025] The snap-fitting notches 11 are distributed at equal intervals on the outer surface of the driving shaft 1, wherein the snap-fitting notches 11 and the driving shaft 1 are of an integrated molding design, and two groups of snap-fitting notches 11 are provided, and the two groups of snap-fitting notches 11 are symmetrically distributed along the longitudinal center axis of the driving shaft 1, and are used to limit the position of the stirring portion 2 to avoid the phenomenon of falling off between the stirring portion 2 and the driving shaft 1; the stirring portion 2 is sleeved on the driving shaft 1, and the stirring portion 2 includes a movable sleeve 21 sleeved on the surface of the driving shaft 1, wherein the internal built-in through-slot 23 of the movable sleeve 21 is of a longitudinal through-slot design, and its internal size is slightly larger than the external size of the driving shaft 1. When in use, the movable sleeve 21 will move longitudinally on the surface of the driving shaft 1 under the action of external force, and two plug-in blocks 24 are welded inside the internal built-in through-slot 23, wherein the plug-in blocks 24 are made of a material that can be slightly deformed and reset, and the two plug-in blocks 24 are symmetrically distributed inside the internal built-in through-slot 23. The plug-in block 24 is plugged into the card slot 11. During use, the operator will push the movable sleeve 21 to the position of the card slot 11 on the surface of the driving shaft 1 under the action of external force. When the plug-in block 24 and the card slot 11 are docked, the plug-in block 24 will be carded into the card slot 11 to limit the position of the stirring part 2; the mounting portion 3 is arranged in the stirring part 2, and the mounting portion 3 is used to longitudinally push the plug-in block 24 to plug into the card slot 11. When the plug-in block 24 and the card slot 11 are carded, the plug-in block 24 and the card slot 11 can be separated by pushing the mounting portion 3 upward, and the stirring part 2 and the driving shaft 1 can be carded, adjusted, and disassembled. Three stirring blades 22 are welded to the outside of the movable sleeve 21, and the stirring blades 22 are distributed in a ring shape on the outside of the movable sleeve 21. The angle between adjacent stirring blades 22 is 120°, and the stirring blades 22 are used to stir the material inside the powder gas conveying mixer.

[0026] The effect achieved by the entire embodiment 1 is that when in use, the driving shaft 1 is threadedly fixed to the interior of the powder gas conveying mixer through the mounting member 12 to help connect the driving shaft 1 and the output end of the motor on the powder gas conveying mixer. When in use, the motor on the powder gas conveying mixer will be connected to an external power source to drive the driving shaft 1 to rotate, prompting the stirring part 2 to rotate accordingly, so as to stir the interior of the powder gas conveying mixer. Before installing the driving shaft 1 and the powder gas conveying mixer, the operator will push the movable sleeve 21 to the position of the engaging groove 11 on the surface of the driving shaft 1 under the action of external force. When the plug-in block 24 and the engaging groove 11 are docked, the plug-in block 24 will engage with the engaging groove 11 to limit the position of the stirring part 2. At the same time, when the plug-in block 24 and the engaging groove 11 are engaged, the plug-in block 24 and the engaging groove 11 can be separated by pushing the mounting part 3 upward, and the engaging adjustment and disassembly of the stirring part 2 and the driving shaft 1 can be performed.

[0027] Example 2, as Figure 1-5As shown, a stirring blade structure for a powder gas separation conveying mixer, the mounting portion 3 includes a sliding member 32 arranged inside the built-in through groove 23, the thickness of the sliding member 32 is less than the gap between the driving shaft 1 and the movable sleeve 21, and when in use, the sliding member 32 will move longitudinally between the movable sleeve 21 and the driving shaft 1 under the external force of the operator, and the stirring portion 2 also includes a limiting groove 26 opened inside the built-in through groove 23, the limiting groove 26 is arranged between the two plug-in blocks 24, and is distributed at 90 degrees with the plug-in blocks 24, and the mounting portion 3 also includes a welding on one side of the bottom of the sliding member 32 and inserted into the limiting groove 26 The limit block 33 is connected, wherein the limit groove 26 limits the limit block 33 so that the limit block 33 can move inside the limit groove 26 when the sliding member 32 moves. The size of the limit block 33 is adapted to the size of the limit groove 26, and the size of the limit block 33 is slightly smaller than the size of the limit groove 26. The interior of the built-in through groove 23 is also horizontally penetrated by a sliding groove 25. The sliding groove 25 and the limit groove 26 are symmetrically distributed on the center axis inside the built-in through groove 23. The symmetrical design of the limit groove 26 and the sliding groove 25 increases the stability of the sliding member 32 when it moves. The highest ends of the limit groove 26 and the sliding groove 25 are both The limit groove 26 is lower than the plane where the lowest point of the plug-in block 24 is located. The length of the limit groove 26 and the sliding groove 25 are the same, and the planes where the lowest points of the limit groove 26 and the sliding groove 25 are located are higher than the plane where the lowest point of the built-in through groove 23 is located, which limits the moving trajectory of the sliding member 32 while avoiding the phenomenon of falling off between the sliding member 32 and the moving sleeve 21. A push rod 31 that is plugged into the sliding groove 25 is welded on the other side of the bottom of the sliding member 32. When the push rod 31 is located at the inner bottom of the sliding groove 25, the top of the sliding member 32 contacts the bottom of the plug-in block 24, and the push rod 31 extends away from the end of the sliding member 32 to the sliding groove 25, when the stirring blade 22 stirs different materials, its surface will inevitably be worn. When the surface wear is too great to affect the use of the stirring blade 22, the push rod 31 inside the sliding groove 25 can be pushed. At this time, the push rod 31 will move the sliding part 32 upward under the action of external force. Since the push rod 31 and the limit block 33 are both arranged at the bottom of the sliding part 32, when the push rod 31 is located at the top of the sliding groove 25, the top of the sliding part 32 will contact the plug-in block 24, causing the plug-in block 24 to shrink and separate from the card slot 11. At this time, the stirring part 2 can be disassembled or the position can be adjusted.

[0028] Working principle: When in use, the driving shaft 1 is threadedly fixed to the inside of the powder gas conveying mixer through the mounting piece 12 to help connect the driving shaft 1 and the output end of the motor on the powder gas conveying mixer. When in use, the motor on the powder gas conveying mixer will be connected to an external power source to drive the driving shaft 1 to rotate, prompting the stirring part 2 to rotate accordingly, so as to stir the inside of the powder gas conveying mixer. Before installing the driving shaft 1 and the powder gas conveying mixer, the operator will push the movable sleeve 21 to the position of the engaging groove 11 on the surface of the driving shaft 1 under the action of external force. When the plug-in block 24 and the engaging groove 11 are docked, the plug-in block 24 will engage with the engaging groove 11 to limit the position of the stirring part 2. At the same time, when the plug-in block 24 and the engaging groove 11 are engaged, the stirring part 2 will be clamped. After connection, the mounting portion 3 can be pushed upward to separate the plug-in block 24 and the engaging slot 11, and the engaging adjustment and disassembly of the stirring portion 2 and the driving shaft 1 can be performed. After the stirring blade 22 stirs different materials, its surface will inevitably be worn. When the surface wear is too great to affect the use of the stirring blade 22, the push rod 31 inside the sliding groove 25 can be pushed. At this time, the push rod 31 will move the sliding part 32 upward under the action of external force. Since the push rod 31 and the limit block 33 are both arranged at the bottom of the sliding part 32, when the push rod 31 is located at the top of the sliding groove 25, the top of the sliding part 32 will contact the plug-in block 24, causing the plug-in block 24 to shrink and separate from the engaging slot 11. At this time, the stirring portion 2 can be disassembled or the position can be adjusted.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
