A plurality of swing rods 6 are installed on the flange 5. The other end of the swing rod 6 is fixed with a vertical support rod 7. The support rod 7 is evenly fixed with a plurality of second stirring rods 8 in the direction towards the first rotating shaft 2. The first stirring rods 4 and the second stirring rods 8 are arranged in a staggered manner up and down. The support rod 7 is fixed with a scraping plate 9 close to the barrel body 1 direction.

[0017] The first rotating shaft 2 is coaxially fixed with a first bevel gear 10 located below the barrel body 1. The first bevel gear 10 meshes with a second bevel gear 11. The second bevel gear 11 is coaxially fixed with a second horizontal rotating shaft 12. Below the barrel body 1, a support leg 13 is fixed. On the right side of the support leg 13, a feed pipe 14 is fixed. The second rotating shaft 12 is rotatably connected to the feed pipe 14. The second rotating shaft 12 is coaxially fixed with a spiral blade 15 located inside the feed pipe 14. The barrel body 1 and the feed pipe 14 are connected through a pipeline 16.

[0021] A feed inlet 22 is provided above the barrel body 1.

[0022] A discharge outlet 23 is provided on the right side of the feed pipe 14.

[0023] When the utility model is in use, the production raw material of the sintered foil is aluminum powder slurry, which needs to be fully stirred during the production process.
