[0037] Please refer to the details. Figure 3 , 4 The drive device 30 uses a motor paired with a worm gear reducer to drive the stirring device 40 to rotate within the stirring cylinder 20. The specific fixing and connection methods can utilize existing technology. The conveying device 50 is a vacuum conveying device 50, which includes a conveying cylinder 51. The conveying cylinder 51 has at least one feeding port 511; in this invention, the conveying cylinder 51 has two feeding ports 511 for connection to the interior of the conveying cylinder 51. The vacuum conveying device 50, also known as a vacuum conveyor, is a dust-free, closed-loop pipeline conveying equipment that uses vacuum suction to transport granular and powdery materials. It utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipeline, driving the movement of the powdery materials, thereby completing the powder conveying. my country has introduced advanced foreign vacuum technology, continuously improving and refining it, and it is now widely used in various light and heavy industries such as chemical, pharmaceutical, food, metallurgy, building materials, and agricultural products. Vacuum conveying is a closed-loop pipeline transportation method that eliminates dust pollution, improves the working environment, and reduces contamination of materials by the environment and personnel, thus increasing cleanliness. Because it is a pipeline system, it occupies little space, enabling the transport of powder materials in confined spaces and creating a more aesthetically pleasing work environment. It is also not limited by distance. Furthermore, vacuum conveyors reduce manual labor intensity and improve work efficiency, making them the preferred method for conveying most powder materials.

[0038] Please refer to the details. Figure 3 , 4 The conveying device 50 also includes a connecting cylinder 52 disposed below the conveying cylinder 51 and a connecting hopper 53 disposed below the connecting cylinder 52. The upper part of the connecting cylinder 52 is connected to the lower part of the conveying cylinder 51 by a clamp.

Each first rotating blade 42 includes a first horizontal portion 421 perpendicular to the outer wall of the rotating shaft 41, a first vertical portion 422 connected to and perpendicular to the first horizontal portion 421 at its upper end, and a first inclined portion 423 connected to the lower part of the first vertical portion 422 and inclined to the outer wall of the rotating shaft 41. The first vertical portion 422 is arranged parallel to the rotating shaft 41 and there is a certain distance between them. Furthermore, to improve the stirring efficiency and uniformity, the first rotating blade 42 has two arrangement methods; please refer to [link to relevant documentation] for details. Figure 1 One type is where the structure and dimensions of the first rotating blade 42 are completely identical, but the first rotating blade 42 is set at a different height. Please refer to [link / reference]. Figure 2 Another type is: the structure of the first rotating blade 42 is the same, but the size is slightly different. Along the outer wall of the rotating shaft 41, the length of the first horizontal part 421 gradually decreases, and the distance between the first vertical part 422 and the rotating shaft 41 gradually decreases, so that the material at different heights or different longitudinal directions is stirred.

[0042] Please see Figure 7 The workbench 11 is also equipped with an observation window 113 and a movable sealing cover 14. The subsequent processes can be observed through the observation window 113 and sealed by the sealing cover 14.

[0043] The working principle of this mixing and feeding device is as follows:

[0044] The material is conveyed into the mixing drum 20 by the conveying device 50. The driving device 30 drives the mixing device 40 to mix the material in the mixing drum 20. The uniformly mixed material is discharged into the cloth sleeve 70 through the feed screw 80. The cloth sleeve 70 can be closed at any time to prevent the mixed material from being discharged.

[0045] In summary, the mixing and feeding device for bio-based degradable materials of this invention uses a conveying device to transport materials.
