[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the drive motor drives the stirring shaft to rotate synchronously through the transmission shaft and the planetary gear set in the planetary reduction gearbox. When the transmission shaft and the stirring shaft rotate clockwise, the transmission shaft drives the stirring frame to stir the powder. At the same time, the stirring shaft drives the powder to be continuously conveyed upward through the spiral conveying blades inside the guide sleeve and the conical hopper, which prevents the powder from falling through the guide sleeve and improves the mixing effect of the powder. The air injection pipe injects dry hot air into the inner side of the bottom of the conical hopper through the diversion air injection ring, which can dry the powder while stirring, and realize the adjustment of the dryness of the powder. Multiple one-way valves are provided inside the diversion air injection ring to prevent the powder from entering the inner side of the diversion air injection ring and causing blockage. 2. This invention achieves a speed difference between the drive shaft and the stirring shaft by rotating the drive shaft counterclockwise after mixing the powder. This difference is achieved through the planetary gear set, allowing the stirring frame, with a speed greater than that of the stirring shaft, to stir and agitate the powder, thus maintaining a continuous supply of material to the spiral conveyor blades and preventing material interruption. The electric push rod, via the transmission bar, moves the sealing sleeve downwards outside the guide sleeve and into contact with the upper end face of the conical positioning seat. This sealing sleeve actively seals the gap between the guide sleeve and the conical positioning seat, preventing powder leakage during packaging bag replacement. The installation height of the connecting sleeve relative to the stirring shaft is adjusted by tightening the knob, thereby adjusting the distance between the conical positioning seat and the guide sleeve and regulating the powder output.

[0020] Please see Figure 1 An embodiment of the present invention provides a vertical spiral packaging machine for bottom-filling of bags, comprising a mounting drive mechanism 1, the mounting drive mechanism 1 including a mounting frame 101, a conical hopper 103 mounted on the inner side of the mounting frame 101, the mounting frame 101 and the conical hopper 103 being fixedly connected by multiple support seats 102, a cover plate 104 being fixedly mounted on the upper end of the conical hopper 103, two injection pipes 105 being fixedly mounted on the upper end face of the cover plate 104, the upper end of the injection pipes 105 being provided with a sealing cap, the conical hopper 103 being connected through the inner side of the two injection pipes 105, a drive motor 106 being installed between the two injection pipes 105, an exhaust valve 107 being installed on one side of the drive motor 106, the drive motor 106 and the exhaust valve 107 being fixedly connected to the cover plate 104, the conical hopper 103 being able to inject and mix different powders through the injection pipes 105.
[0021] Please see Figures 2 to 6A material guiding and sealing mechanism 2 is installed at the bottom of the drive mechanism 1. The material guiding and sealing mechanism 2 includes a material guiding sleeve 201. A diversion air injection ring 204 is fixedly installed on the outer side of the upper end of the material guiding sleeve 201. Multiple first support legs 206 are fixedly installed on the upper end of the diversion air injection ring 204. The upper end of the material guiding sleeve 201 is fixedly connected to the mounting frame 101 through the multiple first support legs 206. An air injection pipe 205 is fixedly provided on one side of the diversion air injection ring 204. Multiple one-way valves are provided on the inner side of the diversion air injection ring 204. The one-way valves are inserted into the inner side of the upper end of the material guiding sleeve 201. The material guiding sleeve 201 and the air injection pipe 205 are connected through the diversion air injection ring 204. The air injection pipe 205 injects dry hot air into the inner side of the bottom end of the conical hopper 103 through the diversion air injection ring 204, which can perform drying operation while the powder is being stirred, thereby adjusting the degree of powder drying. Two guide bars 208 are fixedly installed on one side of the material guide sleeve 201. A transmission bar 207 is slidably connected between the two guide bars 208. A closed sleeve 202 is installed at the bottom end of the transmission bar 207. An electric push rod 203 is fixedly installed on the inner side of one of the first support legs 206. The output end of the electric push rod 203 is fixedly connected to the upper end of the transmission bar 207.

[0022] Please see Figures 2 to 7 A mixing and conveying mechanism 3 is installed inside the drive mechanism 1 and the material guiding and closing mechanism 2. The mixing and conveying mechanism 3 includes a drive shaft 305. The upper end of the drive shaft 305 passes through the cover plate 104 and is connected to the output end of the drive motor 106 via a coupling. A mixing frame 304 is fixedly installed on the outer side of the drive shaft 305. A planetary reduction gearbox 306 is installed at the bottom end of the drive shaft 305.

The retaining crossbar 308 is rotatably connected to the stirring shaft 301. Both ends of the retaining crossbar 308 are fixedly connected to the upper end of the guide sleeve 201. The stirring shaft 301 and the guide sleeve 201 are coaxial. The transmission shaft 305 drives the stirring shaft 301 to rotate synchronously through a planetary gear set. When the transmission shaft 305 and the stirring shaft 301 rotate clockwise, the transmission shaft 305 drives the stirring frame 304 to perform a stirring operation on the powder. The planetary reduction gearbox 306 has a planetary gear set inside. The upper end of the stirring shaft 301 passes through the spiral conveying blade 303 and the retaining bar 308 and is connected to the bottom end of the transmission shaft 305 through the planetary gear set. The planetary reduction gearbox 306 is fixedly connected to the conical hopper 103 through two second support legs 307. The transmission shaft 305 and the stirring shaft 301 have the same rotation direction. The rotation speed of the stirring shaft 301 is less than that of the transmission shaft 305. The transmission shaft 305 and the stirring shaft 301 have a speed difference under the transmission action of the planetary gear set. The powder can be stirred and moved by the stirring frame 304 with a rotation speed greater than that of the stirring shaft 301, thereby maintaining a continuous supply of material to the spiral conveying blade 303 and avoiding the situation where the spiral conveying blade 303 stops conveying material.
[0023] Please see Figure 2 and Figure 8 A sealing and positioning unit 302 is installed on the outer side of the bottom end of the stirring shaft 301. The sealing and positioning unit 302 includes a conical positioning seat 309, which is slidably connected to the stirring shaft 301. A connecting sleeve 310 is fixedly installed in the middle of the conical positioning seat 309. A locking knob 311 is installed on one side of the connecting sleeve 310. One end of the locking knob 311 passes through the connecting sleeve 310 and is in contact with the surface of the bottom end of the stirring shaft 301.

The installation height of the connecting sleeve 310 relative to the stirring shaft 301 is adjusted by the locking knob 311 to adjust the distance between the conical positioning seat 309 and the guide sleeve 201, thereby adjusting the output of powder.
[0024] In summary, the powder to be packaged is injected into the inner side of the conical hopper 103 through the injection pipe 105. The power is turned on and the drive motor 106 is started. Under the support of the cover plate 104, the drive motor 106 drives the stirring shaft 301 to rotate synchronously through the transmission shaft 305 and the planetary gear set in the planetary reduction gear box 306. When the transmission shaft 305 and the stirring shaft 301 rotate clockwise, the transmission shaft 305 drives the stirring frame 304 to stir the powder. At the same time, the stirring shaft 301 drives the powder to be continuously conveyed upward through the spiral conveying blades 303 inside the guide sleeve 201 and the conical hopper 103. This prevents the powder from falling through the guide sleeve 201 and improves the mixing effect of the powder. The crossbar 308 can support the rotation of the stirring shaft 301 and keep the stirring shaft 301 and the guide sleeve 201 coaxial. The conical hopper 103 and the air injection pipe 205 are connected through the flow-dividing air injection ring 204, so that the air injection pipe 205 injects dry hot air into the inner side of the bottom of the conical hopper 103 through the flow-dividing air injection ring 204. At this time, the dry hot air can dry the powder while it is being stirred, thereby adjusting the degree of dryness of the powder. The air is vented through the exhaust valve 107. Multiple one-way valves are provided on the inner side of the flow-dividing air injection ring 204 to prevent the powder from entering the inner side of the flow-dividing air injection ring 204 and causing blockage. After the powder is mixed, the drive shaft 305 is rotated counterclockwise, so that the drive shaft 305 and the stirring shaft 301 have a speed difference under the transmission action of the planetary gear set. Then, when the stirring shaft 301 conveys the powder in the conical hopper 103 to the packaging bag through the spiral conveying blades 303, the stirring frame 304 with a speed greater than that of the stirring shaft 301 can stir and move the powder, thereby maintaining a continuous supply of material to the spiral conveying blades 303 and avoiding the situation of material interruption in the conveying of the spiral conveying blades 303. When changing the packaging bag, the electric push rod 203 is activated. Under the support of the first support leg 206, the electric push rod 203 drives the closed sleeve 202 to move down outside the guide sleeve 201 and come into contact with the upper end face of the conical positioning seat 309 through the transmission bar 207. The closed sleeve 202 can actively seal the gap between the guide sleeve 201 and the conical positioning seat 309 to prevent powder leakage during the packaging bag change. The connecting sleeve 310 and the stirring shaft 301 are locked together by the locking knob 311. The installation height of the connecting sleeve 310 relative to the stirring shaft 301 is adjusted by the locking knob 311 to adjust the distance between the conical positioning seat 309 and the guide sleeve 201, thereby adjusting the output of powder.
