[0021] See also Figures 1 to 3 The utility model provides a technical solution: a powder auxiliary feeding device, comprising a mounting frame 1 and a feeding funnel 2,

[0022] A feed hopper 2 and a guide tube body 3 are installed on the top of the mounting frame 1, the bottom of the feed hopper 2 is connected to the bottom of the guide tube body 3, a control box 101 is installed on the upper side of the mounting frame 1, a feed auger 301 is rotatably installed inside the guide tube body 3 through a bearing seat, a transmission motor 302 is installed on the top of the guide tube body 3 through a locking bolt, and the lower side of the transmission motor 302 is connected to the top of the feed auger 301 through a coupling, a guide frame 5 and a rolling roller 501 are installed inside the feed hopper 2, a servo motor 502 is installed on the outside of the feed hopper 2, and one side of the servo motor 502 is connected to the rolling roller 501 on the adjacent side through an output shaft;

[0023] A transmission gear 503 and a driven gear 505 are respectively installed on the adjacent sides of the two rolling rollers 501, and the sides where the transmission gear 503 and the driven gear 505 are close to each other are respectively meshed with the adjusting gear 504 on the adjacent side, and the outer sides of the two adjusting gears 504 are meshed with each other, and the adjusting gear 504 is rotatably connected to the connecting column. A vibration screening mechanism 6 is arranged at the bottom of the rolling roller 501, and the vibration screening mechanism 6 includes a mounting frame 601 elastically connected to the feed funnel 2 through a connecting spring 602, a vibration motor 603 is installed on the upper side of the mounting frame 601, and a filter screen 604 is installed inside the mounting frame 601, a reserved opening 7 is opened on one side of the feed funnel 2, and a baffle 701 is rotatably installed on the side of the feed funnel 2 close to the reserved opening 7, and the bottom of the baffle 701 is plugged into an elastic limit pin.

[0024] In specific implementation, according to Figures 1 to 3 In order to prevent the powder from containing large pieces of solids when feeding, after the powder is put into the feeding funnel 2, the powder will be guided along the mounting frame 601 inside the feeding funnel 2 and fall between the two rolling rollers 501. The servo motor 502 is started by the control box 101 to drive the rolling roller 501 connected thereto to rotate. When the rolling roller 501 rotates, the transmission gear 503 meshes with the adjusting gear 504 on one side through the meshing action of the gears, and the adjusting gear 504 meshes with the driven gear 505 on one side, thereby completing the relative movement between the two rolling rollers 501 and the rolling of large pieces of powder;

[0025] After the powder is crushed, it will contact the filter screen 604 inside the installation frame 601 elastically connected to the feed funnel 2 by the connecting spring 602. At this time, the vibration motor 603 outside the filter screen 604 drives the installation frame 601 and the filter screen 604 to vibrate, and the powder material is screened. At this time, the powder that meets the requirements will fall into the bottom of the guide tube body 3. The transmission motor 302 is started to drive the feeding auger 301 installed therewith through the coupling to transport the powder along the guide tube body 3 to the discharge pipe 4 for delivery. At the same time, the powder that does not meet the screening requirements will remain on the upper side of the filter screen 604. The staff can open the baffle 701 through the limit pin and take it out from the reserved opening 7. The powder auxiliary feeding device is provided with a powder crushing and vibration screening mechanism 6, which can improve the quality of the feeding powder and facilitate the subsequent work. Embodiment 2

[0026] See also Figure 3 and Figure 4On the basis of the first embodiment, in order to adjust the powder feeding angle: a discharge pipe 4 is installed on the upper side of the guide pipe body 3, and an adjustment mechanism 8 is arranged at the bottom of the guide pipe body 3.

[0027] In specific implementation, according to Figure 3 and Figure 4 In order to prevent the powder from being unable to effectively adjust its discharging angle during discharging, an adjustable swing plate 803 is installed in the mounting groove 801 opened inside the discharging pipe 4 through the rotating shaft 802. When the discharging direction of the powder needs to be adjusted, the electric telescopic rod 806 is started, and the electric telescopic rod 806 pushes the swing plate 803 hinged with it through the mounting block 804 and the pin shaft 805 forward, driving the swing plate 803 to open a corresponding angle, and the opening angle of the swing plate 803 is adjusted by controlling the extension distance of the electric telescopic rod 806, so as to adjust the discharging angle of the powder. The setting of the mounting groove 801 facilitates the swinging activity of the swing plate 803. At the same time, the swing plate 803 can be driven to swing back and forth by repeatedly controlling the opening and closing of the electric telescopic rod 806 to avoid excessive concentration of powder discharge. The powder auxiliary feeding device is provided with an adjusting mechanism 8, which can adjust the angle of powder discharge and prevent concentrated powder discharge, and is convenient to operate.
