Description

Technical Field

[0001] This invention relates to the field of spinning production technology, and in particular to a spinning return air system. Background Technology

[0002] Spinning, also known as chemical fiber forming, is a process in the manufacture of chemical fibers. It involves converting certain polymer compounds into colloidal solutions or melting them into a melt, which is then extruded through the fine orifices of a spinneret to form chemical fibers. The spinning tunnel is mainly used for airflow distribution, fiber bundle arrangement, and heating systems within spinning equipment. In the dry spinning of nylon, the spinning solution is extruded through a metering pump and spinneret, and the fine stream of the solution enters the spinning tunnel. It is dried under the action of circulating hot air. The return air equipment needs to mix the return air with the fresh air before the heat and humidity treatment equipment. It is suitable when the supply air temperature difference can be large or when the indoor humidity is large. However, most existing return air equipment can only blow air to dry spinning materials at a fixed height when drying spinning materials. It is not easy to adjust to a suitable height and angle for moving air blowing to dry spinning materials as needed, which affects the drying quality and reduces the effectiveness of use. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spinning return air system.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The end of the telescopic hose passes through the assembly frame and extends to the outside of the assembly frame. A fixed horizontal pipe is fixedly connected between the ends of multiple telescopic hoses.

[0010] As a further description of the above technical solution:

[0011] The fixed horizontal tube passes through the spinning channel and is fixedly connected to a fixed exhaust fan. The air inlet of the fixed exhaust fan is fixedly connected to a fixed branch pipe. The end of the fixed branch pipe passes through the spinning channel and the connecting shell and extends into the interior of the connecting shell. The side wall of the adjusting concave plate is connected to a moving component for adjusting the rotation of the movable worm gear.

Multiple drive cams are fixedly sleeved on the outer side wall of the drive rod.

[0016] The present invention has the following beneficial effects:

[0017] The drive assembly allows the drive block, drive motor, drive rod, and drive cam to work together, so that the drive motor drives multiple drive cams on the drive rod to rotate.

This allows for adjustment to the appropriate height and angle for blowing and drying the material as needed, thereby improving the usage effect. Attached Figure Description

A movable branch pipe 16 is rotatably connected between the two sides of the inner wall of the adjustment concave plate 10. A movable blowpipe 17 is fixedly connected to the bottom of the movable branch pipe 16. A movable worm gear 18 is fixedly sleeved on the outer wall of the movable branch pipe 16. One end of the movable branch pipe 16 passes through the adjustment concave plate 10. The plate 10 is rotatably connected to a telescopic hose 19. The end of the telescopic hose 19 passes through the assembly frame 7 and extends to the outside of the assembly frame 7. A fixed horizontal pipe 20 is fixedly connected between the ends of multiple telescopic hoses 19. The end of the fixed horizontal pipe 20 passes through the spinning channel 1 and is fixedly connected to a fixed exhaust fan 21. A fixed branch pipe 22 is fixedly connected to the air inlet of the fixed exhaust fan 21. The end of the fixed branch pipe 22 passes through the spinning channel 1 and the connecting shell 2 and extends into the connecting shell 2. The fixed exhaust fan 21 drives the fixed branch pipe 22 to draw air from the inside of the connecting shell 2.

[0025] The side wall of the adjusting concave plate 10 is connected to a movable component that allows the adjusting movable worm gear 18 to rotate, as shown in the reference. Figure 1 and Figure 3 The moving component includes two moving blocks 23 fixedly connected to the side wall of the adjusting concave plate 10. A moving motor 24 is fixedly connected to the surface of one of the moving blocks 23. A moving worm 25 is fixedly connected to the output end of the moving motor 24.

[0027] Working principle: In use, the extruded filaments are first passed through the connecting shell 2 and between the arc-shaped opening on the assembly frame 7 and the electric heating tube. Then, they pass through the connecting shell 2 and extend to the outside of the connecting shell 2. Next, the electric heating tube is activated to dry the filaments. Then, the assembly fan 5 is activated, so that the air passes through the assembly branch pipe 6, the assembly pipe 4 and the air inlet pipe 3 and is discharged into the spinning channel 1, thereby drying the filaments. Then, the air passes through the air inlet on the connecting shell 2 and is discharged into the connecting shell 2. Then, the air passes through the fixed branch pipe 22. Then, the fixed exhaust fan 21 is activated, so that the air inside the fixed branch pipe 22 is discharged into the fixed horizontal pipe 20. Then, the air passes through the telescopic hose 19, the movable branch pipe 16 and the movable blow pipe 17 to dry the filaments. Then, the air is heated by the electric heating tube, which further accelerates the drying of the filaments and ensures the drying effect of the return air.

[0028] Then, the drive motor 13 is started, which drives multiple drive cams 15 on the drive rod 14 to rotate. The drive cams 15 push the corresponding adjustment arc blocks 9, causing the adjustment arc blocks 9 to move the adjustment support rod 8 and the adjustment spring 11 along the direction on the assembly frame 7. The adjustment support rod 8 also moves the adjustment concave plate 10, causing the adjustment concave plate 10 to adjust the movable blowpipe 17 to a suitable height for air drying, ensuring the adjustment return air drying effect.

[0029] Next, start the mobile motor 24, which drives the movable worm wheel 18 on the mobile worm 25 to rotate. Then, the movable worm wheel 18 drives the movable blowpipe 17 on the movable branch pipe 16 to rotate, so that the movable blowpipe 17 can be adjusted back and forth to a suitable angle to ensure further adjustment of the return air drying effect.
