[0020] Embodiment

[0021] Please refer to Figure 1 - Figure 5 As shown, the present utility model provides a raw material mixer for the processing of electric welding electrodes, including a fixed frame 1. An upper cover 5 is connected to the upper part of the stirring box 10 by bolts, and the whole is a detachable structure, which is convenient for subsequent disassembly and maintenance. A feeding port 6 is arranged on the front side wall of the upper cover 5. A fixed bottom plate 3 is formed below the fixed frame 1. Symmetrical legs 2 are formed on the upper surface of the fixed bottom plate 3. The fixed frame 1 is fixed to the upper ends of the legs 2 by mounting bolts 4. A collection box 9 is opened above the fixed bottom plate 3. The collection box 9 is located below the fixed frame 1, and the collection box 9 can collect the raw material powder after stirring;

[0022] A rectangular operation hole 8 is opened on the support frame 7 at the front side, which is convenient for manual rotation of the limiting frame 17 to realize the restriction of the sealing plate 15. The bottom of the support frame 7 at the front side is connected to the fixed bottom plate 3, and the support frame 7 at the rear side is connected to the rear side wall of the stirring box 10. A sealing groove 14 is opened at the bottom of the stirring box 10. The sealing groove 14 can be used as a discharge port. A sealing plate 15 is clamped inside the sealing groove 14. The raw material powder in the stirring box 10 can be discharged by pulling out the sealing plate 15 outward. A limiting frame 17 is installed on the front side of the stirring box 10 through a damping seat 16. The damping seat 16 and the limiting frame 17 are above the sealing plate 15. When the limiting frame 17 rotates to the vertical direction, it can restrict the sealing plate 15 to prevent the sealing plate 15 from withdrawing from the sealing groove 14. When the limiting frame 17 rotates to the horizontal direction, it can release the restriction on the sealing plate 15, and the sealing plate 15 can be pulled out from the sealing groove 14;

[0023] During processing, first, an appropriate amount of raw material powder is poured into the mixing tank 10 through the feed inlet 6. After mixing, the operator reaches through the operation hole 8 with their hand and rotates the limit frame 17. When the limit frame 17 rotates to the horizontal direction, the restriction on the closing plate 15 can be released, and the closing plate 15 can be pulled out from the closing groove 14. At this time, the raw material powder after mixing flows downward through the closing groove 14 and enters the collection box 9. Then, the collection box 9 can be pulled out from the fixed bottom plate 3 to complete the further collection and transfer of the raw material powder.

[0024] As Figure 1 - Figure 4 As shown in the figure, a mixing tank 10 is fixedly arranged above the fixing frame 1. An arc-shaped inner cavity is formed inside the mixing tank 10. Front and rear symmetric support frames 7 are formed on the front and rear side surfaces of the mixing tank 10. A mixing motor 13 is fixedly installed on the front side surface of the front support frame 7. A rotating shaft 11 is arranged between the two support frames 7. A number of mixing blades 12 are fixedly installed on the outer side surface of the rotating shaft 11. The mixing blades 12 can slightly contact the inner walls of the mixing tank 10 and the upper cover 5, facilitating the scraping up of the raw material powder. A number of through holes are formed on the mixing blades 12, facilitating the flow and layer change of the raw material powder and improving the mixing effect. The front end of the rotating shaft 11 is fixedly connected to the output shaft of the mixing motor 13.

[0025] During mixing, the mixing motor 13 rotates to drive the rotating shaft 11 to rotate, thereby causing the mixing blades 12 to rotate, scraping up the raw material powder inside the mixing tank 10. At the same time, the raw material powder falls back into the mixing tank 10 through the through holes on the mixing blades 12, and the raw material powder inside the mixing tank 10 is disrupted.

[0026] Specific working principle:

[0027] When using this device, first, an appropriate amount of raw material powder is poured into the mixing tank 10 through the feed inlet 6. The mixing motor 13 rotates to drive the rotating shaft 11 to rotate, thereby causing the mixing blades 12 to rotate, scraping up the raw material powder inside the mixing tank 10. At the same time, the raw material powder falls back into the mixing tank 10 through the through holes on the mixing blades 12, and the raw material powder inside the mixing tank 10 is disrupted. After mixing, the operator reaches through the operation hole 8 with their hand and rotates the limit frame 17. When the limit frame 17 rotates to the horizontal direction, the restriction on the closing plate 15 can be released, and the closing plate 15 can be pulled out from the closing groove 14. At this time, the raw material powder after mixing flows downward through the closing groove 14 and enters the collection box 9. Then, the collection box 9 can be pulled out from the fixed bottom plate 3 to complete the further collection and transfer of the raw material powder.
