A material distributing cavity is enclosed between adjacent partitions and the material distributing barrel, and a material distributing outlet is arranged at the bottom of the material distributing barrel, and the size of the material distributing outlet matches the maximum spacing between adjacent partitions. After the additive enters the distribution inlet, it flows into the inside of the distribution chamber. When the third rotating shaft rotates, it drives the partition to start rotating, so that the additive between the partitions and the distribution chamber move together. When the distribution chamber moves until it is connected with the distribution outlet, the additive flows into the second feed port along the distribution outlet. Through the above steps, the ratio of additives and materials entering the mixing bin per unit time can be made the same, thereby realizing quantitative unloading of materials. When the material stops being input, the first feeding bin moves upward, causing the rack to move upward, driving the adjusting gear meshing with it to rotate, thereby causing the valve stem to rotate, driving the feeding valve to close, and stopping the input of additives, so that the input of additives and materials is automatically synchronized, avoiding an imbalance in the input ratio of additives and materials, which affects product quality.

[0031] Working principle: When mixing, the driving motor 4 is started, so that the driving shaft 6 starts to rotate. When the driving shaft 6 rotates, it drives the first gear 7 to start rotating, so that the second gear 10 meshed with it through the reduction transmission chain 8 starts rotating. When the second gear 10 rotates, it drives the first rotating shaft 9 to start rotating. When the first rotating shaft 9 rotates, it drives the spiral blade 19 at the bottom to start rotating. At this time, the material is added to the first feeding bin 15 through the first feeding port 16, and the material enters the interior of the upper barrel 17 along the first feeding port 18. When the spiral blade 19 rotates, the material can be quantitatively transported to the mixing bin. 1, the weight of the material in the mixing bin 1 can be sensed in real time by the gravity sensor 48, so as to control the amount of material added. When the gravity sensor 48 senses that the weight of the material in the mixing bin 1 reaches the set value, the signal is transmitted to the electric lifting rod 49, and the electric lifting rod 49 extends, driving the top first feeding bin 15 to move upward, so that the bottom shaft 41 enters the inside of the first rotating shaft 9 until the bottom of the upper barrel 17 abuts against the bottom of the first feeding bin 15. At this time, the material stops being input into the inside of the mixing bin 1, so that the material input amount can be automatically controlled; When the first rotating shaft 9 rotates, it drives the outer cross bar 11 to start rotating. When the cross bar 11 rotates, it drives the outer ring 12 at the other end to start rotating, so that the second rotating shaft 13 starts rotating. When the second rotating shaft 13 rotates, it drives the stirring rod 14 on the outer side to start rotating. When the stirring rod 14 rotates, it is driven by the resistance of the material to drive the second rotating shaft 13 to start rotating while rotating around the first rotating shaft 9, so as to efficiently mix the materials in the mixing bin 1. At the same time, when the spiral blade 19 rotates, it can turn the materials at the bottom of the mixing bin 1 to the upper part of the mixing bin 1, so that the mixing of the materials is more uniform, and the mixing effect is improved.

[0032] When the first rotating shaft 9 rotates, it drives the driving bevel gear 21 to start rotating, so that the driven bevel gear 22 meshing with it starts rotating. When the driven bevel gear 22 rotates, it drives the third rotating shaft 34 to start rotating. At this time, additives are added to the interior of the second feeding bin 29 through the second feeding port 30. The additives enter the material distribution inlet 33 along the bottom feed port 31. After entering the material distribution inlet 33, the additives flow into the interior of the material distribution cavity 37. When the third rotating shaft 34 rotates, it drives the partition 35 to start rotating, so that the additives between the partitions 35 and the material distribution cavity 37 move together. When the material distribution cavity 37 moves to the material distribution outlet, the additives are added to the material distribution outlet 33. When 36 is turned on, the additive flows into the second feed port 20 along the material distribution outlet 36. Through the above steps, the ratio of the additive and the material entering the mixing bin 1 per unit time can be made the same, thereby realizing quantitative unloading of the material. When the material stops being input, the first feeding bin 15 moves upward, causing the rack 47 to move upward, driving the adjusting gear 46 meshing therewith to rotate, thereby causing the valve stem to rotate, driving the feeding valve 45 to close, and stopping the input of the additive, thereby keeping the input of the additive and the material automatically synchronized, avoiding an imbalance in the input ratio of the additive and the material, and affecting the product quality.

[0033] When the first rotating shaft 9 rotates, it drives the shell 38 to start rotating. At this time, relative sliding occurs between the rotating ring 39 connected to the second feed port 20 through the inclined tube 23 and the shell 38. After the additive enters the second feed port 20, it flows into the interior of the shell 38 along the inclined tube 23. After the additive flows into the shell 38, it falls on the top of the distribution table 42. The conical distribution table 42 can evenly spread the fallen additive. When the shell 38 rotates, the internal distribution table 42 and the baffle 44 are driven to rotate accordingly. When the baffle 44 rotates, the flowing additive is evenly separated, so that the additive is evenly sprinkled along the lower opening 43 at the bottom of the shell 38, thereby achieving uniform spraying of the additive while ensuring the synchronous input of the additive and the material, avoiding uneven distribution of the additive.

[0034] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
