Description

Technical Field

[0001] This utility model relates to the field of nylon spinning production technology, and in particular to a foldable adjustable device for the windless zone of the spinning nozzle of UV-resistant polyamide 6. Background Technology

[0002] like Figure 1 As shown, in the production process of UV-resistant polyamide 6 filament, solid polyamide, after being filtered, mixed, and pressurized under high temperature, is ejected as a molten stream from the spinneret 20. The molten stream is cooled and solidified to form nascent fibers 21. The fiber cooling and solidification is completed in the windless zone 22 and the windy zone 23, as shown. Figure 1 As shown, a channel opening 24 (enclosed by a crossbeam) and a side blowing box 25 are sequentially arranged below the spinneret. The ejected molten stream passes through the channel opening and enters the area of ​​the side blowing box. The distance from the bottom of the channel opening to the bottom of the spinneret is the length of the windless zone, and the area of ​​the side blowing box is the length of the windy zone.

[0003] The length of the windless zone in conventional equipment is generally 8-9cm. When the single fiber DPF (denier denier) is small, the fiber cools faster. For products with relatively coarse denier DPF, the windless zone of ultra-fine denier porous yarn should be appropriately extended to slow down the cooling rate in the windless zone. If the cooling is too fast, it will cause the yarn to have low strength and low elongation, and uneven yarn, which is not conducive to the processing and weaving of subsequent products and affects the dyeing effect of the fabric.

[0004] The existing production equipment is basically designed for conventional products, and it cannot meet the production needs of new products with differentiated ultra-fine denier porous structures. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a foldable and adjustable device for the windless zone of the spinning nozzle of UV-resistant polyamide 6, which can adjust the length of the windless zone according to the needs of the production varieties.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a foldable and adjustable device for the windless zone of the spinning nozzle of UV-resistant polyamide 6, including a fixed rod fixed to the top surface of the crossbeam of the windless zone of the spinning nozzle, a movable rod hinged to the fixed rod, and a movable baffle hinged to the lower end of the movable rod. When the movable baffle is lowered, the distance between the lower edge of the movable baffle and the lower edge of the windless zone is 5cm. When the movable baffle is retracted, the movable baffle is hidden in the windless zone. A fixing member is also provided on the side wall of the crossbeam, and the movable baffle and the fixing member are detachably connected.

[0008] Furthermore, the fixing component is a hook, and the side wall of the movable baffle is provided with a hanging ring. When the movable baffle is retracted, the hanging ring is hung on the hook.

[0009] Furthermore, two fixing rods are provided, which are located on the left and right sides of the crossbeam in the windless zone of the spinning port, respectively, and each fixing rod is connected to a movable rod.

[0010] The advantages of this invention are: the foldable baffle allows the length of the windless zone to be adjusted at any time according to the needs of the production varieties. By extending the length of the windless zone, the cooling time of the fibers is slowed down, thereby achieving more stable physical properties and more stable yarn evenness, and meeting higher product quality requirements.

[0018] Please see Figures 2 to 4 This utility model provides a foldable adjustable device for the windless zone of the spinning nozzle of UV-resistant polyamide 6, including a fixed rod 2 fixed to the top surface of a crossbeam 1 at the windless zone 5 of the spinning nozzle, a movable rod 3 hinged to the fixed rod 2, and a movable baffle 4 hinged to the lower end of the movable rod 3. When the movable baffle 4 is lowered, the distance between the lower edge of the movable baffle 4 and the lower edge of the windless zone 5 is 5cm. Figure 2 As shown, after the movable baffle is lowered, the movable baffle 4 is located in the windy area, thereby blocking part of the air blown out by the side-blowing box. Figure 4As shown, when the movable baffle 4 is retracted, it is hidden within the windless zone 5. A fixing member 6 is also provided on the side wall of the crossbeam 1, and the movable baffle 4 is detachably connected to the fixing member 6. When producing ultra-fine denier porous yarn, the baffle can be lowered to block the airflow from the side-blowing box, thereby extending the length of the windless zone 5. When producing conventional products, the baffle can be retracted within the windless zone 5 to meet the process requirements of conventional products.

[0019] By using a foldable baffle, the length of the windless zone 5 can be adjusted at any time according to the needs of the production varieties. By extending the length of the windless zone 5, the cooling time of the fibers is slowed down, thereby achieving more stable physical properties and more stable yarn evenness, and meeting higher product quality requirements.

[0020] Specifically, the fixing member 6 is a hook, and the side wall of the movable baffle 4 is provided with a hanging ring 7. When the movable baffle 4 is retracted, the hanging ring 7 is hung on the hook.

[0021] Specifically, there are two fixed rods 2, which are located on the left and right sides of the crossbeam 1 in the windless zone 5 of the spinning port, and each fixed rod 2 is connected to a movable rod 3.

[0022] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
