[0029] After the polyacrylonitrile raw yarn spinning position switcher is turned on, the first driving motor 10 can be started, and the output shaft of the first driving motor 10 can drive the telescopic column 8 to move horizontally downward, and the movement of the telescopic column 8 can drive the extrusion plate 14 to move, and the material in the material hopper 6 can be squeezed into the valve body 5 by the movement of the extrusion plate 14. When the extrusion plate 14 moves to a certain position, the extrusion plate 14 applies downward pressure to the pressing plate 16, thereby driving the pressing plate 16 to move downward, and the movement of the pressing plate 16 drives the second slider 15 to move downward, and the movement of the second slider 15 applies pressure to the first slider 13, thereby driving the first slider 13 to move horizontally, and the movement of the first slider 13 drives the moving rod 12 to move horizontally, and the movement of the moving rod 12 drives the limiting plate 11 to move, and the movement of the limiting plate 11 opens the discharge port of the valve body 5, so that the material enters the heating box 4, which can effectively avoid the material from entering the heating box 4 too fast to cause uneven heating, and at the same time avoid the material from being blocked in the valve body 5, thereby improving the production efficiency and the overall product quality.

[0030] A support frame 22 is fixedly installed on the surface of the base 1, and the support frame 22 is parallel to the mounting plate 2. Push grooves are provided on the mounting plate 2 and the support frame 22, and a threaded rod 21 is rotatably installed in the push groove. Moving blocks 25 are threadedly sleeved on the two threaded rods 21, and a cutting plate 26 is fixedly installed between the two moving blocks 25. A transmission belt 23 is wrapped around one end of the two threaded rods 21, and a second drive motor 24 is fixedly installed on one side of the mounting plate 2, and the output shaft of the second drive motor 24 is fixedly connected to one of the threaded rods 21.

[0031] When waste occurs, the second drive motor 24 can be started, and the output shaft of the second drive motor 24 can drive the threaded rod 21 connected thereto to rotate, and the transmission belt 23 wound around the threaded rod 21 can drive another threaded rod 21 to rotate, and the moving block 25 can be moved by the rotation of the threaded rod 21, and the cutting plate 26 can be moved by the movement of the moving block 25. When the cutting plate 26 moves to the spinneret 40, the waste on the spinneret 40 can be effectively cut off, avoiding the risk of burns caused by manual cleaning of broken wire waste, improving safety and reducing workload.

[0032] When the first driving motor 10 drives the telescopic column 8 to reset upward, the extrusion plate 14 is driven to move upward through the telescopic column 8. When the extrusion plate 14 is away from the pressing plate 16, the elastic force of the second spring 18 drives the second slider 15 to quickly reset. The second slider 15 is quickly reset to contact the first slider 13, and the push plate 20 is driven to move by the elastic force of the first spring 17. The movement of the push plate 20 drives the moving rod 12 to move, and the movement of the moving rod 12 drives the limiting plate 19 to quickly reset, which can effectively prevent the material from quickly entering the heating box 4 when the extrusion plate 14 is reset, and prevent the uneven heating of the material in the heating box 4 from causing the product quality to decline.

[0033] Cooling plates 27 are symmetrically fixedly installed on the fixed plate 3. Cooling grooves are opened in the two cooling plates 27. Water pumps 29 are fixedly installed in the cooling grooves. Circulation pipes 30 are fixedly installed on the output shaft and input shaft of the water pump 29. The circulation pipes 30 are filled with coolant. Heat conducting plates 28 are fixedly installed on the surface of the cooling plates 27. The heat carried by the material is absorbed by the heat conducting plates 28, and the coolant in the circulation pipes 30 flows through the water pumps 29, thereby exchanging heat with the heat conducting plates 28. The material temperature can be effectively controlled, wire breakage can be avoided, and production efficiency is improved.

[0034] A feed trough is provided on one side of the material hopper 6, and a feed plate 38 is fixedly installed on the surface of the feed trough. The bottom surface of the feed plate 38 is inclined at 15 degrees, which can effectively and quickly add materials into the material hopper 6, thereby improving production efficiency.

[0035] A collecting trough is provided on the surface of the base 1, in which a third driving motor 32 is fixedly installed, a fan 33 is fixedly connected to the output shaft of the third driving motor 32, and an isolation cover 34 is fixedly installed in the collecting trough. When waste appears, the third driving motor 32 can be started, and the fan 33 can be driven to rotate by the output shaft of the third driving motor 32. The wind force generated by the rotation of the fan 33 blows the waste to one side of the collecting trough. Since the bottom of the collecting trough is inclined, the waste can effectively slide to one side of the collecting trough due to its own gravity. An isolation cover 34 is installed in front of the fan 33, which can effectively prevent the waste from being entangled on the fan 33, thereby improving safety.

[0036] A plurality of legs 37 are fixedly mounted on the bottom surface of the base 1 , and an anti-skid layer is fixedly mounted on the bottom surface of the plurality of legs 37 . The anti-skid layer is made of rubber and can effectively prevent the base 1 from shaking during the production process, thereby improving product quality.

[0037] A separation groove is provided on one side of the base 1, and the separation groove is connected with the collecting groove. A collecting box 35 is slidably installed in the separation groove, and a handle 36 is fixedly installed on the surface of the collecting box 35. When waste slides to one side of the collecting groove, it will slide into the collecting box 35 due to its own gravity. When waste accumulates in the collecting box 35, the handle 36 can be pulled to pull the collecting box 35 out of the separation groove through the pulling force on the handle 36, and then the waste can be recycled.

[0038] In the present invention, after the polyacrylonitrile raw yarn spinning position switcher is turned on, the first driving motor 10 can be started, and the output shaft of the first driving motor 10 can drive the telescopic column 8 to move horizontally downward, and the movement of the telescopic column 8 drives the extrusion plate 14 to move, and the material in the material hopper 6 is squeezed into the valve body 5 by the movement of the extrusion plate 14. When the extrusion plate 14 moves to a certain position, the extrusion plate 14 applies downward pressure to the pressing plate 16, thereby driving the pressing plate 16 to move downward, and the movement of the pressing plate 16 drives the second slider 15 to move downward, and the movement of the second slider 15 applies pressure to the first slider 13, thereby driving the first slider 13 to move horizontally, and the movement of the first slider 13 drives the moving rod 12 to move horizontally, and the movement of the moving rod 12 drives the limiting plate 11 to move, and the movement of the limiting plate 11 opens the discharge port of the valve body 5, so that the material enters the heating box 4, which can effectively avoid the material from entering the heating box 4 too fast to cause uneven heating, and at the same time avoid the material from being blocked in the valve body 5, thereby improving the production efficiency and the overall product quality.

[0039] In general, with respect to the technical problem: in the existing polyacrylonitrile precursor spinning position switcher, the material is manually placed into the material trough. When too much material is placed in the material trough, the pipeline is prone to blockage. In addition, since the amount of material entering the heating box 4 cannot be controlled, the material is insufficiently heated in the heating box 4, which greatly affects the production efficiency and overall product quality of the polyacrylonitrile precursor spinning position switcher; a technical solution is adopted: through the cooperation of the limiting plate 11, the moving rod 12, the pressing plate 16, the first slider 13, the second slider 15, the extrusion plate 14 and the first drive motor 10, when the material enters the material hopper 6, the uneven heating of the material in the heating box 4 can be effectively avoided, and at the same time, the clogging of the material in the valve body 5 can be avoided, thereby improving the production efficiency and the overall product quality; because the implementation process of the technical solution is: after the polyacrylonitrile precursor spinning position switcher is turned on, the first drive motor 10 can be started, and the output shaft of the first drive motor 10 can drive the telescopic column 8 to move in water The second slider 15 is driven downward by the movement of the pressing plate 16, and the movement of the second slider 15 applies pressure to the first slider 13, thereby driving the first slider 13 to move horizontally, and the movement of the first slider 13 drives the moving rod 12 to move horizontally, and the movement of the moving rod 12 drives the limiting plate 11 to move, and the movement of the limiting plate 11 opens the discharge port of the valve body 5 to allow the material to enter the heating box 4; therefore, the technical problem can be solved inevitably, and the technical effect achieved is: it can effectively avoid the material from entering the heating box 4 at too fast a speed, resulting in uneven heating, and at the same time avoid the material from being blocked in the valve body 5, thereby improving the production efficiency and the overall product quality.

[0040] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
