This process needs to be carried out under specific temperature and pressure conditions to ensure the uniformity and quality of the fibers.

[0031] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: a spinning box for high-tenacity polyamide fiber spinning preparation, including a box body 1, an outer wall of the box body 1 is fixedly connected with an air intake branch pipe 2, a valve 3 is arranged in the middle of the air intake branch pipe 2, a bracket 4 is fixedly connected in the middle of the outer wall of the box body 1, a slide rod 5 is slidably connected in the middle of the bracket 4, one end of the slide rod 5 is fixedly connected with a first limit plate 6, a middle side of the slide rod 5 is fixedly connected with a second limit plate 7, a spring 8 is arranged on the outer side of the slide rod 5, a clamping plate 9 is fixedly connected to the other end of the slide rod 5, the bottom of the valve 3 is on the middle side of the clamping plate 9, and an air intake assembly is arranged on the top of the air intake branch pipe 2.

[0033] When it is necessary to limit the valve 3, the sliding rod 5 can be driven to slide inside the bracket 4 by pulling the card plate 9. At this time, the second limit plate 7 can be moved away from the bracket 4 and the spring 8 can be compressed. When the card plate 9 is pulled out, the card plate 9 and the valve 3 are in a mutually perpendicular state by rotating the card plate 9. At this time, the card plate 9 is released, and the elastic force of the spring 8 can be used to drive the card plate 9 close to the bracket 4, so that the card plate 9 and the valve 3 are engaged with each other to limit the movement of the valve 3. Therefore, in the production process, the restriction of the valve 3 by the card plate 9 can avoid accidental contact of the staff, resulting in the rotation of the valve 3, thereby affecting the safety of production. When it is necessary to adjust the valve 3, the card plate 9 is separated from the valve 3 by pulling the card plate 9, and then the card plate 9 is rotated to drive the sliding rod 5 to rotate. By rotating the card plate 9 to be parallel to the valve 3, the card plate 9 is released, and the elastic force of the spring 8 can be used to pull the card plate 9 close to the bracket 4, and the separation of the card plate 9 and the valve 3 can be completed.

[0034] Reference Figure 2 A card slot 10 is provided on one side of the middle of the card plate 9, and the bottom of the valve 3 is located inside the card slot 10. The valve 3 can be clamped by the card slot 10 to prevent the valve 3 from rotating when it is accidentally touched.

[0035] Reference Figure 1 The air intake assembly includes an air intake manifold 11 and a connecting pipe 12. The top of the air intake branch pipe 2 is fixedly connected to the bottom of the air intake manifold 11, and the middle of the top surface of the connecting pipe 12 is fixedly connected to the middle of the top surface of the air intake manifold 11. Gas can be transported through the air intake branch pipe 2, the air intake manifold 11 and the connecting pipe 12.

[0036] Reference Figure 2 A sliding hole is provided in the middle of the bracket 4, and the sliding rod 5 is located inside the sliding hole. The sliding hole can provide space for the movement of the sliding rod 5.

[0037] Reference Figure 1 An oil inlet pipe 13 is provided in the middle of the front side of the housing 1. The heat transfer oil can be transported through the oil inlet pipe 13.

[0038] Reference Figure 3-Figure 4, an inner wall of the box body 1 is fixedly connected with an inner liner box 14, and an insulation layer 17 is fixedly connected between the inner liner box 14 and the box body 1. A heating pipe 16 is arranged inside the inner liner box 14, and a temperature sensor 15 is fixedly connected to the inner wall of the inner liner box 14. There are multiple temperature sensors 15 and heating pipes 16, and the multiple temperature sensors 15 and heating pipes 16 are evenly distributed inside the inner liner box 14. Through the multiple temperature sensors 15 and heating pipes 16 arranged inside the inner liner box 14, the temperature of each area of ​​the inner liner box 14 can be detected and monitored. When the temperature is too low, the area with lower temperature can be heated by driving the heating pipe 16, thereby avoiding the phenomenon of uneven temperature distribution inside the memory box, which leads to a reduction in the final quality of the polyamide fiber, and the temperature can be prevented from being transferred to the box body 1 through the insulation layer 17, thereby avoiding the loss of heat.

[0039] Working principle: When in use, the flow of air inside the air intake branch pipe 2 can be controlled by controlling the opening and closing of the valve 3. When the valve 3 needs to be restricted, the sliding rod 5 can be driven to slide inside the bracket 4 by pulling the card plate 9. At this time, the second limit plate 7 can be moved away from the bracket 4 and the spring 8 can be compressed. When the card plate 9 is pulled out, the card plate 9 and the valve 3 are made perpendicular to each other by rotating the card plate 9. At this time, the card plate 9 is released, and the elastic force of the spring 8 can be used to drive the card plate 9 close to the bracket 4, so that the card plate 9 and the valve 3 are engaged with each other, and the movement of the valve 3 can be restricted by inserting the bottom of the valve 3 into the card groove 10 of the card plate 9. Therefore, in the production process, the restriction of the valve 3 by the card plate 9 can prevent the staff from accidentally touching it and causing the valve 3 to rotate. Rotation, thereby affecting the safety of production, when the valve 3 needs to be adjusted, the card plate 9 is separated from the valve 3 by pulling the card plate 9, and then the card plate 9 is rotated to drive the slide bar 5 to rotate, and the card plate 9 is rotated to be parallel to the valve 3. At this time, the card plate 9 is released, and the elastic force of the spring 8 can be used to pull the card plate 9 close to the bracket 4, and the card plate 9 can be separated from the valve 3. In addition, during use, the temperature of each area of ​​the liner box 14 can be detected and monitored by means of multiple temperature sensors 15 and heating tubes 16 arranged inside the liner box 14. When the temperature is too low, the heating tube 16 can be driven to heat the area with lower temperature, thereby avoiding the phenomenon of uneven temperature distribution inside the memory box, which in turn leads to a decrease in the final quality of the polyamide fiber.
