[0032] The mixing device for raw materials for producing lyocell fibers comprises a housing 1, a rotating rod 2, two stirring frames 3, a moving plate 10, a driving motor 11 and an electric push rod 9;

[0033] The cylindrical inner wall of the shell 1 is inclined, the rotating rod 2 is vertically rotatably arranged inside the shell 1, and the two stirring frames 3 are respectively fixedly arranged on both sides of the rotating rod 2 by fixing components, and each fixing component includes two fixing plates 6 and a plurality of bolts 7, and a first groove adapted to the rotating rod 2 is provided between the two fixing plates 6, so that the two fixing plates 6 clamp the rotating rod 2, and a second groove adapted to a side frame of the stirring frame 3 is provided between the two fixing plates 6, so that the two fixing plates 6 clamp the side frame of the stirring frame 3, and a plurality of fixing holes 17 are provided on the rotating rod 2 and the side frame of the stirring frame 3, and each bolt 7 passes through each fixing hole 17, respectively, and the two fixing plates 6 are fixed by the bolts 7, so that the two fixing The fixed plate 6 fixes the rotating rod 2 and the stirring frame 3, so that the rotating rod 2 drives the stirring frame 3 to rotate, thereby mixing and stirring the raw materials inside the shell 1, and a plurality of stirring blades 5 are fixed vertically and evenly spaced inside each stirring frame 3, and each stirring blade 5 is inclined. When the stirring frame 3 drives the stirring blade 5 to rotate, the inclined stirring blade 5 will cause the raw materials to roll, thereby improving the stirring and mixing effect. The side of each stirring frame 3 close to the inner wall of the shell 1 is inclined, and the inclined side angle of the stirring frame 3 is consistent with the inclined angle of the cylindrical inner wall of the shell 1. Two electric push rods 9 are provided on the top of the shell 1, and the moving plate 10 is fixedly arranged on the top of the two electric push rods 9, and the two electric push rods 9 are respectively located on both sides of the bottom of the moving plate 10 The driving motor 11 is fixedly arranged on the top of the moving plate 10, and the top of the rotating rod 2 is rotatably connected to the middle part of the moving plate 10, and the top of the rotating rod 2 is connected to the driving motor 11. The driving motor 11 can drive the rotating rod 2 to rotate, so that the stirring frame 3 stirs the raw materials, and the moving plate 10 can also be driven downward by the electric push rod 9, so that the rotating rod 2 moves vertically downward, so that the inclined edge of each stirring frame 3 contacts the cylindrical inner wall of the shell 1, and the bottom edge of each stirring frame 3 contacts the bottom inner wall of the shell 1. Since the inclined edge angle of the stirring frame 3 is consistent with the inclined angle of the cylindrical inner wall of the shell 1, the inclined edge of each stirring frame 3 is in contact with the cylindrical inner wall of the shell 1. At this time, the driving motor 11 drives When the stirring frame 3 is rotated, the attachments on the cylindrical inner wall of the shell 1 can be scraped off by the inclined edge of the stirring frame 3, and the attachments on the inner wall of the bottom end of the shell 1 can be scraped off by the bottom edge of the stirring frame 3. A rubber strip 4 is provided on the bottom and one side of the inclined edge of the stirring frame 3. The rubber strip 4 contacts the inner wall of the shell 1 to avoid damage to the inner wall of the shell 1. A reinforcement sleeve 8 is fixedly connected to the inner wall of the top end of the shell 1. The rotating rod 2 passes through the reinforcement sleeve 8. A reinforcement cylinder 16 is fixedly connected to the inner wall of the bottom end of the shell 1. The bottom end of the rotating rod 2 is located inside the reinforcement cylinder 16. The reinforcement sleeve 8 and the reinforcement cylinder 16 can reinforce the top and bottom of the rotating rod 2 respectively to facilitate its rotation, thereby driving the stirring frame 3 to mix and stir the raw materials.

[0034] In order to facilitate the discharge of mixed materials;

[0035] Reference Figure 1 An opening is provided at the bottom of one side of the shell 1, and a discharge barrel 12 is provided at the opening. One end of the discharge barrel 12 is closed and is threadedly connected with a threaded rod 13. A sealing plate 15 is provided at one end of the threaded rod 13. The sealing plate 15 is located inside the opening of the shell 1, and a rotating rod is fixedly connected to one end of the threaded rod 13. A discharge port 14 is provided at the middle bottom end of the discharge barrel 12. The axis of the discharge barrel 12 is perpendicular to the inclined outer wall of the shell 1. The sealing plate 15 can be moved inside the discharge barrel 12 through the threaded rod 13, thereby opening the opening to facilitate the discharge of the mixed material.

[0036] The working principle of the mixing device for raw materials for lyocell fiber production is as follows: the rotating rod 2 is driven to rotate by a driving motor 11, and the rotating rod 2 drives the stirring frames 3 on both sides thereof to rotate accordingly, so that the raw materials inside the housing 1 are stirred and mixed by the stirring frames 3 and the stirring blades 5, and the inclined stirring blades 5 can make the raw materials roll, thereby improving the stirring and mixing effect. During the stirring and mixing process, the moving plate 10 is reciprocated up and down by the electric push rod 9, so that the rotating rod 2 is moved up and down, so that the stirring frame 3 and the stirring blades 5 are moved up and down, and the areas of different depths of the raw materials are stirred, thereby improving the stirring effect;

[0037] Furthermore, the movable plate 10 can be lowered by the electric push rod 9, so that the rotating rod 2 drives the stirring frame 3 to lower, so that its inclined edge contacts the inclined inner wall of the outer shell 1, and the bottom edge of the stirring frame 3 contacts the bottom inner wall of the outer shell 1, so as to scrape off the attachments on the outer shell 1. On the one hand, it can avoid that the inner wall of the outer shell 1 is attached with raw materials during mixing and stirring, resulting in uneven mixing. On the other hand, after the mixing is uniform, the attachments on the inner wall of the outer shell 1 can be scraped off to avoid affecting the uniformity of the subsequent mixed product.

[0038] When the raw materials are discharged after being evenly mixed, the threaded rod 13 is rotated by the rotating rod to move it horizontally, thereby driving the sealing plate 15 to leave the opening of the shell 1, so that the evenly mixed raw materials inside the shell 1 enter the discharge barrel 12 through the opening and are then discharged through the discharge port 14.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
