[0012] The present invention also provides a usage method of a processing device for uniformly curing spinning. The specific method includes the following steps:

[0013] Step 1: The spinneret sprays a thin stream of stock solution into the upper duct. The thin stream of stock solution passes through the inside of the upper duct, the middle duct, and the lower duct assembly. In the duct, the solvent in the thin stream of stock solution is carried away by hot air, turning the liquid into a solid fiber filament.

[0014] Step 2: During the process of the thin stream of stock solution passing through the upper duct, the input pipe is connected to an external hot air blower. Hot air is blown into the upper duct through the hot air duct and the air inlet, blowing towards the surface of the thin stream of stock solution. Under the action of the high-temperature gas, part of the solvent is evaporated and carried away. It enters the arc-shaped cover through the air return port and the air return rectifier, reducing the solvent concentration in the air. Then it enters the converging pipe and further heated under the action of the air heating mechanism through the reflux air inlet pipe. The hot air is blown into the middle duct, stirred evenly, and blown into the inside of the inner cylinder through each ventilation hole to further heat and cure the passing thin stream of stock solution. Then the cured fiber filament enters the lower duct assembly and continues to be acted upon by hot air, and the remaining solvent inside is evaporated and carried away. Since the structures of the lower duct assembly and the upper duct assembly are the same, the solvent concentration in the air will be reduced finally and enter the reflux air inlet pipe again, heated by the air heating mechanism and blown into the middle duct assembly again to achieve circulation. During the process, the reversing valve is opened and closed regularly to make the piston cylinder intake or exhaust air, driving the guide plate to rotate. The guide plate swings, thereby changing the air flow direction around the fiber filament, enabling the low-temperature air around the fiber filament to exchange heat with the high-temperature air in the duct to ensure the curing effect on the fiber filament.

[0015] Step 3: The fiber filament leaves the duct from the bottom of the lower duct assembly and enters the working box. The fiber filament passes between the left and right upper guide rollers, then enters the oiling mechanism. The part passing through the oiling mechanism is oiled. After oiling, it passes between the left and right lower guide rollers and is finally wound on the surface of the winding drum for subsequent processing.

[0016] Preferably, the inside of the piston cylinder is communicated with the inside of the adjacent bronchus. The top of the gear is meshed with the bottom of the toothed ring.

The piston cylinder 251 is fixedly connected to the outer wall of the upper duct 21. Inside the piston cylinder 251, a piston 252 is slidably arranged. In the middle of the side of the piston 252 close to the upper duct 21, an adjustment rod 253 is fixedly arranged. The adjustment rod 253 slidably penetrates through the outer wall of the upper duct 21. One end of the adjustment rod 253 away from the piston cylinder 251 is rotatably provided with a slider 254. The slider 254 is slidably connected to the bottom of the corresponding guide plate 24. An external spring 255 is sleeved on the adjustment rod 253.

[0037] Through the mutual cooperation among the guide plate 24, the angle adjustment mechanism 25, the bronchus 28 and the reversing valve 210, the air intake and exhaust in the angle adjustment mechanism 25 can be flexibly controlled, thereby driving the guide plate 24 to rotate. The swinging guide plate 24 can change the air flow direction around the fiber filament, enabling the low-temperature air around the fiber filament to exchange heat with the high-temperature air in the channel in time, quickly evaporating the harmful high-concentration solvent in the fiber filament, and ensuring the curing effect on the fiber filament. Through the mutual cooperation among the cold water storage cylinder 271, the arc-shaped cover 272 and the inclined catheter 273, the hot air with solvent entering the arc-shaped cover 272 can be cooled, causing the solvent to liquefy and remain in the arc-shaped cover 272, thereby reducing the solvent concentration in the air so as to continue to blow into the channel later to carry away the remaining evaporated solvent.,

[0038] As Figure 1 and 10 The second embodiment is shown. The main difference from the first embodiment is that a processing device for uniformly curing spinning includes a raw material box 8. The raw material box 8 is fixedly connected to the top of the accommodating box 1. A spinneret 9 is fixedly provided in the middle of the inner cavity bottom of the accommodating box 1. The spinneret 9 is connected to the raw material box 8 through a spinning pipe. On the left and right sides of the spinneret 9 at the inner cavity bottom of the accommodating box 1, hot air ducts 10 are fixedly provided. A working box 11 is fixedly provided at the bottom of the lower channel assembly 4. A motor 12 is fixedly provided at the lower right of the working box 11. The output end of the motor 12 penetrates through the right wall of the working box 11 and is fixedly provided with a winding drum 13. The left end of the winding drum 13 is rotatably connected to the left wall of the inner cavity of the working box 11. Upper guide rollers 14 are rotatably provided between the front and rear walls on the upper left and right sides of the inner cavity of the working box 11. An oiling mechanism 15 is fixedly provided between the front and rear walls of the inner cavity of the working box 11 and below the two upper guide rollers 14. Lower guide rollers 16 are rotatably provided between the front and rear walls on the lower left and right sides of the inner cavity of the working box 11. An input pipe is fixedly provided at the front end of the accommodating box 1. The upper parts of the two hot air ducts 10 are connected to the inside of the input pipe.,

[0039] Through the mutual cooperation among the inner cylinder 32, the heat insulation layer 33, the arc-shaped blades 34 and the ventilation holes 35, the hot air re-blowed into the duct can be evenly agitated in advance, so that the hot air evenly passes through the surface of the fiber filaments downward, without causing the fiber filaments to swing sharply. Through the mutual cooperation among the toothed ring 276, the micro-motor 277 and the gear 278, the arc-shaped cover 272 can be driven to rotate, so that it is in full contact with the cold water in the cold water storage cylinder 271, improving the heat exchange efficiency.

[0040] The embodiment of the present invention also provides a usage method of a processing device for uniformly curing spinning. The specific method includes the following steps:

[0041] Step 1: The spinneret 9 sprays a thin stream of spinning solution upward into the interior of the duct 21. The thin stream of spinning solution passes through the interior of the upper duct 21, the middle duct 31 and the lower duct assembly 4. In the duct, the solvent in the thin stream of spinning solution is carried away by the hot air, turning the liquid into solid fiber filaments.

[0042] Step 2: During the process that the stock solution trickle passes through the upper duct 21, the input pipe is connected to an external hot air blower, and hot air is blown into the upper duct 21 through the hot air duct 10 and the air inlet 22, and blows towards the surface of the stock solution trickle. Under the action of the high-temperature gas, part of the solvent is evaporated and carried away, and enters the arc-shaped cover 272 through the air return port 23 and the air return rectifier 26. Since cold water flows through the cold water storage cylinder 271, the hot air with the solvent enters the arc-shaped cover 272 and will fully contact the inner wall of the arc-shaped cover 272, and heat exchange is realized with the cold water, so that the solvent is liquefied and remains in the arc-shaped cover 272, and the solvent concentration in the air is reduced. Then it enters the converging pipe 7, and through the reflux air inlet pipe 6, it is further heated under the action of the air heating mechanism 5. The hot air blows into the middle duct 31, and the arc-shaped blade 34 pushes the inner cylinder 32 to rotate under the blowing of the air flow. The hot air is stirred evenly and blows into the inside of the inner cylinder 32 through each ventilation hole 35, further heating and solidifying the passing stock solution trickle. Then the solidified fiber filaments enter the lower duct assembly 4 and continue to be affected by the hot air, and the remaining solvent inside is evaporated and carried away. Since the structures of the lower duct assembly 4 and the upper duct assembly 2 are the same and both are provided with a solvent liquefaction mechanism 27, the hot air with the solvent enters the solvent liquefaction mechanism 27 on the lower duct assembly 4, so that the solvent is liquefied and remains therein, thereby reducing the solvent concentration in the air. Then it enters the reflux air inlet pipe 6 and is heated by the air heating mechanism 5 again and blows into the middle duct assembly 3, realizing circulation. During the process, the reversing valve 210 is opened and closed regularly. Since the reversing valve 210 can change the gas flow direction, when the reversing valve 210 is opened, first the gas in the converging pipe 7 enters the piston cylinder 251, and under the action of the air pressure, the adjusting rod 253 is pushed, and then the guide plate 24 is pushed away from the inner wall of the upper duct 21. Then the reversing valve 210 is controlled again, and under the elastic action of the spring 255, the gas in the piston cylinder 251 is discharged, and at the same time, the guide plate 24 is driven to rotate and approach the inner wall of the upper duct 21. During the process, the guide plate 24 swings, thereby changing the air flow direction around the fiber filaments, enabling the low-temperature air around the fiber filaments to exchange heat with the high-temperature air in the duct, and ensuring the solidification effect on the fiber filaments;

[0043] Step 3: The fiber filaments leave the duct from the bottom of the lower duct assembly 4 and enter the working box 11. The fiber filaments pass between the left and right upper wire guide rollers 14, and then enter the oiling mechanism 15. The part passing through the oiling mechanism 15 is oiled. After the oiling is completed, it passes between the left and right lower wire guide rollers 16 and is finally wound on the surface of the winding drum 13 for subsequent processing.

4. A method for using the processing equipment for uniformly curing spinning as described in claim 3, characterized in that: The method comprises the following steps: Step 1, the spinneret (9) sprays a thin stream of stock solution into the upper channel (21). The thin stream of stock solution passes through the inside of the upper channel (21), the middle channel (31) and the lower channel assembly (4). In the channel, the solvent in the thin stream of stock solution is carried away by hot air, and the liquid state is transformed into a solid fiber filament. Step 2, during the process that the thin stream of stock solution passes through the upper channel (21), the input pipe is connected to an external hot air blower, and hot air is blown into the upper channel (21) through the hot air conduit (10) and the air inlet (22) and blown onto the surface of the thin stream of stock solution. Under the action of the high-temperature gas, part of the solvent is evaporated and carried away, enters the arc-shaped cover (272) through the air return port (23) and the air return rectifier (26), so that the solvent concentration in the air is reduced, then enters the converging pipe (7), and through the reflux air inlet pipe (6), is further heated under the action of the air heating mechanism (5). The hot air is blown into the middle channel (31), is stirred and blown into the inside of the inner cylinder (32) through each vent hole (35) to further heat and cure the passing thin stream of stock solution. Then the cured fiber filaments enter the lower channel assembly (4) and continue to be acted on by hot air, and the remaining solvent inside is evaporated and carried away. Since the structures of the lower channel assembly (4) and the upper channel assembly (2) are the same, the solvent concentration in the air will be reduced finally, and then enters the reflux air inlet pipe (6) again, is heated by the air heating mechanism (5) and blown into the middle channel assembly (3) again to realize circulation. During the process, the reversing valve (210) is opened and closed regularly to make air enter or exhaust in the piston cylinder (251), drive the guide plate (24) to rotate, the guide plate (24) swings, and further change the air flow direction around the fiber filament, so that the low-temperature air around the fiber filament exchanges heat with the high-temperature air in the channel to ensure the curing effect on the fiber filament. Step 3, the fiber filaments leave the channel from the bottom of the lower channel assembly (4) and enter the working box (11). The fiber filaments pass between the left and right upper guide rollers (14), then enter the oiling mechanism (15), the part passing through the oiling mechanism (15) is oiled, and after the oiling is completed, it passes between the left and right lower guide rollers (16) and is finally wound on the surface of the winding drum (13) for subsequent processing.
