[0052] In the embodiment of the present application, the bottom of the rotating distributing disc 803 is fixedly provided with a vertical linkage rod 805, the bottom of the vertical linkage rod 805 is fixedly installed with a horizontal support part 806, the top of the horizontal support part 806 is fixedly installed with a scraping plate 807 which is in close contact with the inner wall of the first mixing box 302, the scraping plate 807 is fixedly installed with a second mixing part 808 on one side, in the process of controlling the synchronous rotation of the rotating distributing disc 803 on the left and right sides, the vertical linkage rod 805 which rotates synchronously with the rotating distributing disc 803 drives the scraping plate 807 and the second mixing part 808 to rotate, the sliding of the scraping plate 807 along the inner wall of the first mixing box 302 realizes the scraping of the adhered material, and then the rotation of the second mixing part 808 realizes the full mixing of the raw material and the solvent oil, thereby preparing the first mixed solution and the second mixed solution, the top of the rotating distributing disc 803 is fixedly installed with a center separation ring 809 which has the same center as the rotating distributing disc 803, the bevel gear ring 404 is fixedly installed on the top of the center separation ring 809, the bottom of the rotating distributing disc 803 is provided with a flow-through opening 810 which is located inside the center separation ring 809, the bottom of the agent storage tank 802 is communicated with a flow guide pipe 811 which extends to the inside of the center separation ring 809, the first auger is arranged inside the flow guide pipe 811 and is fixedly connected with the rotating distributing disc 803, the solvent oil in the agent storage tank 802 is gradually conveyed to the inside of the center separation ring 809 along the flow guide pipe 811 through the rotating action of the first auger, the solvent oil which flows into the inside of the center separation ring 809 flows downward along each flow-through opening 810 into the corresponding first mixing box 302, the solvent oil which flows into the first mixing box 302 realizes full mixing with the powdery or granular raw material which is dispersed into it, thereby preparing the first mixed solution and the second mixed solution.

[0053] In the embodiment of the application, the inside circumferential array of the rotating distribution disc 803 is provided with a plurality of distribution mounting ports 812, and the inside circumferential array of the rotating distribution disc 803 is provided with a plurality of inclined material guiding tables 813. In the process of controlling the synchronous rotation of the rotating distribution discs 803 on the left side, the bevel gear ring 404 rotating synchronously with the rotating distribution disc 803 drives the first bevel gear 603 to rotate. When the intermittent discharge port 602 rotates to realize the communication with the corresponding storage box 406, the raw materials in the storage box 406 enter the intermittent discharge pipe 601 along the intermittent discharge port 602. When the intermittent discharge port 602 again realizes the communication with the discharge port at the bottom of the bulk material channel 405, the raw materials in the intermittent discharge pipe 601 are gradually dispersed into the inside of the rotating distribution disc 803 in a rotating state. In this process, the raw materials falling on each inclined material guiding table 813 slide along the smooth inclined surface and gather at each distribution mounting port 812, which is arranged between adjacent two inclined material guiding tables 813. The distribution assembly 9 includes a second rotating shaft connected inside the corresponding distribution mounting port 812 through a torsion spring, and a distribution turnover plate 901 fixedly installed inside the distribution mounting port 812 on the second rotating shaft. The end of the second rotating shaft penetrating through the rotating distribution disc 803 is fixedly provided with a second bevel gear 902 matched with the arc-shaped bevel gear part 402. The distribution turnover plate 901 in the initial state is horizontally arranged inside the corresponding distribution mounting port 812.

[0054] After the required amount of ultra-high molecular weight polyethylene fibers, ceramic fibers and aluminum oxide whiskers are respectively placed in the corresponding storage boxes 406, the required capacity of solvent oil is placed in the storage tank 802, and the required amount of copper powder (of course, iron powder can also be selected) is placed in the copper powder storage pipe 313. Then, the distribution control motor 310 is started to control the synchronous rotation of the rotating distribution discs 803 on the left side. In the process of controlling the synchronous rotation of the rotating distribution discs 803 on the left side, the bevel gear ring 404 rotating synchronously with the rotating distribution disc 803 drives the first bevel gear 603 to rotate. When the intermittent discharge port 602 rotates to realize the communication with the corresponding storage box 406, the raw materials in the storage box 406 enter the intermittent discharge pipe 601 along the intermittent discharge port 602. When the intermittent discharge port 602 again realizes the communication with the discharge port at the bottom of the bulk material channel 405, the raw materials in the intermittent discharge pipe 601 are gradually dispersed into the inside of the rotating distribution disc 803 in a rotating state. In this process, the raw materials falling on each inclined material guiding table 813 slide along the smooth inclined surface and gather at each distribution mounting port 812 (i.e. the position of the distribution turnover plate 901).

[0055] In the process of controlling the synchronous rotation of the rotary material distribution plates 803 on the left and right sides, when each second bevel gear 902 contacts the arc-shaped bevel gear part 402 at the corresponding position and rolls along it, it can drive each ring-shaped material turnover plate 901 to rotate by a certain angle, thereby causing the solid raw materials on each material turnover plate 901 to slide through the material installation port 812 and be dispersed into the first mixing box 302. When the second bevel gear 902 is disengaged from the arc-shaped bevel gear part 402, the reverse reset of each material turnover plate 901 to the horizontal state can be achieved by the elastic force of the torsional spring. Through the above-mentioned method, the intermittent turnover and material falling of each material turnover plate 901 can be achieved, thereby causing the solid raw materials to be dispersed into the first mixing box 302 intermittently. At the same time, in the process of controlling the synchronous rotation of the rotary material distribution plates 803 on the left and right sides, the solvent oil in the storage tank 802 is gradually transported into the inside of the center separation ring 809 along the flow guide pipeline 811 through the rotation of the first auger. The solvent oil flowing into the inside of the center separation ring 809 flows into the corresponding first mixing box 302 along each through-flow port 810. The solvent oil flowing into the first mixing box 302 is fully mixed with the powdered or granular raw materials dispersed into it. The vertical linkage rod 805 rotating synchronously with the rotary material distribution plate 803 drives the scraper plate 807 and the second mixing component 808 to rotate. The sliding of the scraper plate 807 along the inner wall of the first mixing box 302 realizes the scraping of the adhered materials. The rotation of the second mixing component 808 realizes the full mixing of the raw materials and the solvent oil. Thus, the first mixed solution and the second mixed solution can be prepared.

[0056] After the preparation of the first mixed solution and the second mixed solution is completed, the two control valves 306 on the left and right sides are opened, and the first mixed solution and the second mixed solution flow into the second mixing box 303 at the same time. In this process, the corresponding first gear 307 is controlled to rotate by the material control motor 310. The synchronous rotation of the two first gears 307 is realized under the cooperation of the transmission belt 309 and the transmission wheel 308. The second gear rotating synchronously with the first rotating shaft drives the inner tooth ring 314 to rotate, and the third gear is driven to rotate synchronously by the inner tooth ring 314. Thus, the first mixing component 315 rotating synchronously with the inner tooth ring 314 is rotated. In the process of rotation of the inner tooth ring 314, it drives the second auger to rotate inside the copper powder storage pipe 313. The copper powder in the copper powder storage pipe 313 is gradually transported and dispersed into the second mixing box 303 by the rotation of the second auger. Thus, the full mixing of the copper powder, the first mixed solution and the second mixed solution can be realized, and finally the spinning dope is prepared.
