Since the gas can be hot gas, cold gas, or pure gas other than air, a variety of different airflows can be generated for the filaments in the first inner cavity, which can isolate the air, provide hot airflow or cold airflow, maintain a particle-free environment, etc., and can provide different airflow environments to adapt to the filament forming of different spinning and the production requirements of different products.

[0027] Please refer to Figure 1 In an embodiment of the present application, a production adapter mechanism 100 is provided, which is applied to chemical fiber manufacturing equipment. The chemical fiber manufacturing equipment includes an outer ring blowing cooling device. In other embodiments, it can be other chemical fiber manufacturing equipment. The outer ring blowing cooling device is used as an example to illustrate, which includes a wire outlet mechanism 200 and a bellows mechanism 300. The wire outlet mechanism 200 is a structure for spinning and forming in the above-mentioned device, such as a spinneret. The bellows mechanism 300 has a spinning channel 301, which is an area for external ring blowing cooling of the ejected spinning. The production adapter mechanism 100 is arranged between the wire outlet mechanism 200 and the bellows mechanism 300. The production adapter mechanism 100 is provided with a suction hole 111 and a first inner cavity 112. The setting of the first inner cavity 112 enables the wire outlet mechanism 200 to pass through the first inner cavity 11 2 then enters the bellows mechanism 300, that is, after the filaments are produced, the spun fibers first pass through the first inner cavity 112 and then enter the spinning channel 301. The two ends of the suction hole 111 are respectively connected to the first inner cavity 112 and the outside of the production adapter mechanism 100. The suction hole 111 runs through the inside and outside of the production adapter mechanism 100. The suction hole 111 at the inner end is connected to the first inner cavity 112, and the suction hole 111 at the outer end is connected to the air environment outside the production adapter mechanism 100. The suction hole 111 can generate positive pressure or negative pressure on the first inner cavity 112 to form an airflow in the first inner cavity 112. Since the suction hole 111 is provided, positive pressure or negative pressure can be provided to the suction hole 111 at the outer end of the suction hole 111, so that the airflow can be led out of the first inner cavity 112 or injected into the first inner cavity 112, thereby forming an airflow.

[0028] The present application conducts the airflow at the initial position of the silk output, and can provide more airflow environments for the silk output in the first inner cavity 112 through the suction hole 111, and can provide positive pressure or negative pressure through the suction hole 111, so that air can be sucked or gas can be supplied to the first inner cavity 112. Since the gas can be hot gas, cold gas, or pure gas other than air, a variety of different airflows can be generated for the silk output in the first inner cavity 112, which can isolate the air, provide hot airflow or cold airflow, maintain a particle-free environment, etc., and can provide different airflow environments to adapt to different spinning silk output forming and meet the production requirements of different products.

The temperature of the spinning box is generally 200-300°C, which is relatively high. After the filaments come out from the bottom, they need to be cooled by blowing air in an outer ring. The heat insulation plate 120 is used to prevent the high temperature of the upper spinning box mechanism 400 from being transferred to the inner cavity and the spinning channel 301, thereby ensuring the spinning formation. In an optional embodiment, the suction hole 111 can also be directly set on the suction plate 110, and the suction plate 110 is an insulating material, so the setting of the heat insulation plate 120 can be omitted.

The suction hole 111 is opened on the side of the suction plate 110 to form an independent air flow channel, so that the air in the first inner cavity 112 of the suction plate 110 can be connected with the air outside the suction plate 110, which has two functions. One is to discharge the crystals, powder or other particles in the wire-forming environment out of the entire outer ring blowing cooling device, and the other is to be able to inject gas into the first inner cavity 112 during wire forming, so as to form an atmosphere environment such as cold wind, hot wind or isolated air at the initial position of the wire.
