[0032] The utility model is connected with a stirring box 5 at the bottom of the premixing box 1, and a stirring shaft 6 is rotatably installed inside the stirring box 5 through a bearing, and a motor 7 is provided for transmission connection with the stirring shaft 6, an exhaust pipe 10 is provided on the top of the stirring box 5, and a protective net 11 is provided at one end of the exhaust pipe 10 connected to the stirring box 5, and a filter screen 8 is provided at the upper end of the stirring box 5, and the filter screen 8 is rotatably connected to the stirring shaft 6 through a bearing, and a first scraper 9 is provided on the stirring shaft 6 to fit the filter screen 8, so that the premixed various raw material mixtures will enter the stirring box 5 and fall on the filter screen 8, and at the same time, the stirring shaft 6 is controlled by the motor 7 to drive the first scraper 9 to rotate, and the mixed materials on the filter screen 8 can be scraped by the first scraper 9, so that the materials falling on the filter screen 8 pass through the filter screen 8 and evenly fall into the mixing box, so that the uniformity of different materials when entering the mixing box can be further improved, thereby improving the material leveling effect;

[0033] During this process, excess airflow will be discharged outward through the exhaust pipe 10, intercepting the material inside the mixing box 5. The setting of the protective filter can prevent the material from being discharged outward from the exhaust pipe 10 along with the airflow.

[0041] See also Figure 1-Figure 5As an implementation of the stirring shaft 6 : the bottom end of the stirring shaft 6 extends to the discharge pipe 12 and is provided with a spiral discharge blade 24 .

[0042] Specifically, when the evenly mixed material is discharged outward, the stirring shaft 6 can drive the spiral discharge blades 24 to rotate when rotating. The spiral discharge blades 24 can control the discharge of the material at the discharge pipe 12, improve the controllability of the discharge, and avoid the situation where the material is blocked at the discharge pipe 12.

[0043] In summary, when the overall equipment is in use:

[0044] The raw material is conveyed into the premixing box 1 through the feed pipe 3, and at the same time, the high-pressure airflow is conveyed into the premixing box 1 through the air intake pipe 4. In this way, under the action of the high-pressure airflow, the powder can be prompted to flow in the spiral guide channel 13. Due to the spiral setting, the airflow carrying the raw material will automatically roll when flowing in the spiral backflow channel, so that the raw material can be automatically rolled and mixed during the conveying process in the premixing box 1, and premixing can be achieved;

[0045] Afterwards, the premixed material will be evenly transported to the mixing box 5 through the feed pipe 14 and the feed branch pipe 15, and land on the filter screen 8, and the excess airflow will be discharged through the exhaust pipe 10;

[0046] The motor 7 is started, and the stirring shaft 6 is controlled by the motor 7 to drive the first scraper 9 to rotate. The first scraper 9 can scrape the mixed material on the filter screen 8, so that the material falling on the filter screen 8 passes through the filter screen 8 and falls into the mixing box evenly. In this way, the uniformity of different materials when entering the mixing box can be further improved, thereby improving the material mixing effect;

[0047] The setting of the protective filter can prevent the material from being discharged from the exhaust pipe 10 along with the air flow;

[0048] Synchronously, when the stirring shaft 6 rotates, the first spiral blade 16 and the second spiral blade 17 can be driven to rotate, so as to achieve stirring in the middle position of the stirring box 5. At the same time, when the stirring shaft 6 rotates, the stirring horizontal frame 20 and the stirring inclined frame 21 can be driven to rotate, so as to achieve stirring of the material at the bottom end of the stirring box 5, thereby improving the effect of uniform mixing of the material in the stirring box 5.

[0049] When the stirring shaft 6 rotates, it can synchronously drive the stirring rod 18 and the second scraper 19 to rotate. The stirring rod 18 can further enhance the stirring and stirring effect of the middle section of the stirring box 5, thereby improving the mixing uniformity of the materials. The second scraper 19 can scrape the inner wall of the stirring box 5 to prevent the materials from adhering to the inner wall of the stirring box 5.

[0050] After mixing is completed, when the evenly mixed material is discharged outward, the stirring shaft 6 can drive the spiral discharge blades 24 to rotate when rotating. The spiral discharge blades 24 can control the discharge of the material at the discharge pipe 12, improve the controllability of the discharge, and avoid the situation where the material is blocked at the discharge pipe 12.
