[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0023] Embodiments of this utility model:

[0024] like Figures 1-5As shown, this utility model provides a countercurrent mixing device for composite cable materials, including a base plate 1 and a mixing cylinder 2. A countercurrent mixing mechanism 3 is installed inside the mixing cylinder 2. The countercurrent mixing mechanism 3 includes a first double-helix stirring rod 31 and multiple second double-helix stirring rods 32. The multiple second double-helix stirring rods 32 are distributed around the first double-helix stirring rod 31. The first double-helix stirring rod 31 includes a first rod body 311, on which two first helix stirring blades 312 are symmetrically arranged, with opposite helical directions. The second double-helix stirring rods 32 include a second rod body 321, on which two second helix stirring blades 322 are symmetrically arranged, with opposite helical directions. A mechanism box 4 is installed at one end of the mixing cylinder 2. A gear set connected to the countercurrent mixing mechanism 3 is installed inside the mechanism box 4. The gear set includes a first gear 6 and multiple second gears 7. The first gear 6 is connected to the first rod body 311. The body 311 is fixedly sleeved, the second gear 7 is fixedly sleeved with the second rod body 321, and multiple second gears 7 are meshed with the first gear 6. A drive motor 5 connected to the first double helical stirring rod 31 is provided on the outside of the mixing cylinder 2. A support seat 22 for supporting the drive motor 5 is provided on the bottom plate 1. When the first double helical stirring rod 31 is driven to rotate by the drive motor 5, multiple second double helical stirring rods 32 will also rotate under the meshing of the second gears 7 with the first gear 6, and the rotation direction is opposite to that of the first double helical stirring rod 31. While the first double helical stirring rod 31 and the second double helical stirring rod 32 are stirring the material in the mixing cylinder 2, they will also push the material to move. The opposite rotation makes the material circulate in the mixing cylinder 2. During the circulation process, the material pushed by the first double helical stirring rod 31 will be mixed countercurrently with the material pushed by the second double helical stirring rod 32, which improves the mixing effect and efficiency.

[0025] like Figures 1-5 As shown, a support frame 8 is provided on the base plate 1, and multiple hoppers 9 are provided on the support frame. A guide pipe 10 is connected between the hoppers 9 and the mixing cylinder 2, and a discharge pipe 11 is provided at the bottom of the mixing cylinder 2. A first slide valve 12 is provided on the guide pipe 10, and a second slide valve 13 is provided on the discharge pipe 11. With this configuration, different materials can be added to the multiple hoppers 9 according to actual needs. The speed of material introduction and discharge can be controlled by the first slide valve 12 and the second slide valve 13.

[0026] like Figures 1-5As shown, the mixing cylinder 2 includes a cylinder body 201. Rotating grooves are formed on the inner wall of the cylinder body 201 near both ends. A rotating plate 202 is installed in each rotating groove, and a first sealed bearing 23 adapted to the rotating plate 202 is installed within the rotating groove. A mechanism box 4 is connected to the rotating plate 202. Second sealed bearings 24 are installed on both the rotating plate 202 and the rotating box. A first rod 311 and a second rod 321 are adapted to the second sealed bearings 23. Two support plates 14 are installed on the bottom plate 1, and a rotating shaft 15 is rotatably connected between the two support plates 14. A first sprocket 16 is sleeved on the first double-helix stirring rod 31. Multiple evenly distributed teeth 17 are arranged around the outer surface of the mechanism box 4. A second sprocket 18 is installed on the rotating shaft 15. A transmission chain 20 is provided between the third gear 19, the first sprocket 16, and the second sprocket 18. The third gear 19 meshes with the locking teeth 17. With this arrangement, the first double-helix stirring rod 31 and multiple second double-helix stirring rods 32 can be driven by the drive motor 5 to stir the material. At the same time, the rotating shaft 15 is rotated by the transmission cooperation between the first sprocket 16, the second sprocket 18, and the transmission chain 20. The meshing cooperation between the third gear 19 and the locking teeth 17 drives the mechanism box 4 and the rotating plate 202 to rotate, thereby driving the countercurrent mixing mechanism 3 to rotate, which further improves the mixing effect of the material. It is worth mentioning that the rotation direction of the countercurrent mixing mechanism 3 is opposite to the rotation direction of the first double-helix stirring rod 31.

[0027] like Figures 1-5 As shown, a cleaning mechanism 21 is provided inside the mixing cylinder 2. The cleaning mechanism 21 cleans and scrapes off the material on the inner wall of the mixing cylinder 2. The cleaning mechanism 21 includes two connecting rings 211. Multiple cleaning scrapers 212 that contact the inner wall of the mixing cylinder 2 are provided between the two connecting rings 211. Connecting posts 213 are provided on the sides of the two connecting rings 211. The connecting posts 213 are connected to the rotating plate 202.

[0028] Specifically, by opening the first gate valve 12, the material in the hopper 9 is introduced into the mixing cylinder 2 through the guide pipe 10. Then, the drive motor 5 is started, driving the first double-helix stirring rod 31 to rotate. With the second gear 7 meshing with the first gear 6, multiple second double-helix stirring rods 32 also rotate. While the first double-helix stirring rod 31 and the second double-helix stirring rod 32 stir the material in the mixing cylinder 2, they also push the material to move. The opposite rotation causes the material to circulate in the mixing cylinder 2. During the circulation process, the material pushed by the first double-helix stirring rod 31 will interact with the material pushed by the second double-helix stirring rod 32. The spiral stirring rod 32 pushes the moving material to mix in a countercurrent manner. While stirring the material, the rotating shaft 15 rotates through the transmission between the first sprocket 16, the second sprocket 18 and the transmission chain 20. The meshing of the third gear 19 and the clamping gear 17 drives the mechanism box 4 and the rotating plate 202 to rotate, thereby driving the countercurrent mixing mechanism 3 to rotate. The rotating plate 202 drives the cleaning mechanism 21 to rotate, scraping off the material adhering to the inner wall of the mixing cylinder 2 to reduce residue. After mixing is completed, the material is discharged through the discharge pipe 11 by opening the second gate valve 13.
