Description

Technical Field

[0001] This utility model relates to the field of fiber production, specifically a rapid dehumidification treatment device for chemical fiber after molding. Background Technology

[0002] In the production process of chemical fiber, a certain amount of moisture usually remains after the fiber is formed. If it is not dehumidified in a timely and effective manner, it will not only affect the physical properties of the fiber, but may also cause problems such as adhesion, breakage and uneven dyeing in subsequent processing, thereby reducing product quality and production efficiency.

[0003] Currently, common dehumidification methods for synthetic fibers mainly include traditional methods such as hot air drying and natural air drying. Hot air drying uses a fan to blow heated air onto the fiber surface to evaporate surface moisture. While it can achieve dehumidification to some extent, its effectiveness in removing moisture from the fiber interior or tightly adhered fibers is limited, and it suffers from high energy consumption, uneven drying, and potential fiber damage. Natural air drying, on the other hand, is greatly affected by ambient temperature and humidity, has low drying efficiency, and cannot meet the needs of modern continuous production. Furthermore, most existing dehumidification equipment uses a single airflow method for drying, lacking an effective structure for further cleaning residual moisture from the fiber surface. This results in the possibility of localized dampness or impurities adhering to the fibers after drying, affecting the consistency and stability of the finished product quality. Therefore, overcoming these technical problems and defects is a key issue that needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to overcome the defects described in the background art, thereby realizing a rapid dehumidification treatment device for chemical fiber after molding. The device adopts a dual-mode dehumidification method that combines pneumatic drying and contact wiping. While using high-speed hot air to blow away and evaporate the moisture on the fiber surface, the sponge ring of the wiping unit directly contacts the fiber surface to absorb residual moisture, thereby achieving a more thorough and efficient dehumidification treatment.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is: a rapid dehumidification treatment device for chemical fiber forming, comprising a device body, a dehumidification chamber inside the device body, multiple air inlet chambers inside the device body below the dehumidification chamber, a gas drying unit for exchanging air and dehumidifying the fiber filaments inside the dehumidification chamber, and a wiping unit for contact dehumidification of the fiber filaments inside the dehumidification chamber.

[0006] In the aforementioned rapid dehumidification treatment equipment after chemical fiber molding, the two ends of the equipment body are respectively provided with a feed port and a discharge port for passing through the fiber filaments, and the feed port and discharge port are both connected to the bottom of the dehumidification chamber.

[0007] In the aforementioned rapid dehumidification treatment equipment for chemical fiber forming, the gas drying unit includes a through hole at the top of the air inlet chamber, through which the air inlet chamber is connected to the dehumidification chamber.

[0008] An assembly plate with a ventilation opening is horizontally fixed inside the through hole, and an exhaust fan with a motor is horizontally fixed on the assembly plate.

[0009] In the aforementioned rapid dehumidification treatment equipment after chemical fiber molding, an exhaust pipe is horizontally fixed inside the dehumidification chamber above the through hole, an impeller is rotatably installed inside the exhaust pipe, and a first motor that drives the corresponding impeller is fixedly installed on the side of the equipment body.

[0010] The bottom end of the exhaust pipe is vertically connected to a first air inlet pipe. The air inlet of the first air inlet pipe is located directly above the through hole. The first air inlet pipe has a long strip structure and its air inlet is in contact with the fiber filament.

[0011] In the aforementioned rapid dehumidification treatment equipment after chemical fiber molding, an exhaust pipe is connected to the top of the exhaust pipe, a dryer is provided on one side of the equipment body, and the air outlet of the exhaust pipe passes through the top of the equipment body and is connected to the air inlet of the dryer.

[0012] The air outlet of the dryer is connected to an air outlet pipe, and the air outlet pipe has multiple air outlets, each of which is connected to a corresponding air inlet chamber.

[0013] In the aforementioned rapid dehumidification treatment equipment for chemical fiber molding, heating wires are horizontally fixed on multiple assembly plates on the side of the discharge port.

[0014] In the aforementioned rapid dehumidification treatment equipment after chemical fiber molding, multiple wiping units are provided, each located between two corresponding exhaust pipes.

[0015] The wiping unit includes a lifting plate horizontally arranged inside the dust removal chamber between every two through holes. At least one guide rod is vertically fixed at the top of the lifting plate, and the top of the guide rod extends through the top of the equipment body and out to the outside.

[0016] A lead screw is rotatably installed at the top center of the lifting plate. The top of the lead screw extends through the top of the equipment body and is threadedly connected to the top of the equipment body.

[0017] In the above-mentioned rapid dehumidification treatment equipment after chemical fiber molding, the lifting plate is a U-shaped structure with the opening facing downwards. At least one rotating roller is horizontally rotatably arranged in the middle position of the two arms of the lifting plate, and each rotating roller is fitted with a sponge ring that contacts the fiber filament.

[0018] The end of the rotating roller extends through the side of the lifting plate and outwards. A second motor is fixedly installed on the lifting plate. Both the output end of the second motor and the end of the rotating roller are fixedly equipped with pulleys, and belts are fitted on the two pulleys.

[0019] In the aforementioned rapid dehumidification equipment for chemical fiber forming, a second air inlet pipe is connected to multiple exhaust pipes on one side of the discharge port, and the air inlet of the second air inlet pipe abuts against the sponge ring of the corresponding rotating roller.

[0020] Beneficial Effect 1: The rapid dehumidification treatment equipment for chemical fiber molding of this utility model adopts a dual-mode dehumidification method that combines pneumatic drying and contact wiping. While using high-speed hot air to blow away and evaporate the moisture on the fiber surface, the sponge ring of the wiping unit directly contacts the fiber surface to absorb residual moisture, thereby achieving a more thorough and efficient dehumidification treatment. At the same time, key components such as the gas drying unit and the wiping unit adopt a modular design, with each component having an independent structure and convenient installation, which facilitates later maintenance, replacement or upgrades, extends the service life of the equipment and reduces maintenance costs.

[0021] Beneficial Effect 2: The rapid dehumidification treatment equipment for chemical fiber molding of this utility model includes a gas drying unit with multiple air inlet chambers and through-hole structures. It is combined with an exhaust pipe, an exhaust pipe, and an external dryer to form an air circulation system, which allows hot air to be evenly distributed around the fiber filaments, avoiding uneven drying in certain areas and improving overall drying consistency. The heating wire set on the side of the discharge port can perform secondary heating and drying on the fiber just before it is output, further reducing the fiber moisture content and improving the stability of the finished product quality. The bottom of the exhaust pipe is equipped with a long strip-shaped first air inlet pipe, whose air outlet is directly facing the fiber filaments, which can concentrate the air force on the fiber surface and improve the air volume utilization rate. At the same time, the second air inlet pipe is set near the wiping unit, which can provide localized enhanced air supply to the wiping area and prevent moisture reabsorption.

[0022] Beneficial Effect 3: The rapid dehumidification treatment equipment for chemical fiber molding of this utility model adopts an adjustable structure combining a lifting plate and a guide rod in the wiping unit. Users can flexibly adjust the wiping position according to the height of the fiber filaments. At the same time, the wiping height can be precisely controlled by the screw threaded connection to the top of the equipment, which can adapt to the processing needs of different fiber specifications. The wiping unit is equipped with a rotating roller driven by a second motor, which drives the sponge ring to rotate and wipe the fiber filaments. Compared with the static wiping method, dynamic wiping can more effectively remove residual moisture and attached impurities on the fiber surface, improving cleanliness and drying efficiency.

[0032] The rapid dehumidification treatment equipment for chemical fiber molding of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] See Figures 1-5The rapid dehumidification equipment for chemical fiber forming in this embodiment adopts a dual-mode dehumidification method combining pneumatic drying and contact wiping. While high-speed hot air evaporates moisture from the fiber surface, the sponge ring 504 of the wiping unit 5 directly contacts the fiber surface to absorb residual moisture, thus achieving a more thorough and efficient dehumidification process. In this embodiment, it mainly includes a device body 1. The device body 1 has an inlet 6 and an outlet 7 at both ends for fiber filaments. A dehumidification chamber 2 is formed inside the device body 1, and both the inlet 6 and outlet 7 are connected to the bottom of the dehumidification chamber 2. Fiber filaments enter the dehumidification chamber 2 through the inlet 6 and exit through the outlet 7. Multiple air inlets 3 are formed inside the device body 1 below the dehumidification chamber 2.

[0035] To achieve gas dehumidification of the fiber filaments. See also Figures 1-4 In this embodiment, a gas drying unit 4 for ventilating and dehumidifying the fiber filaments is provided inside the dehumidification chamber 2. The gas drying unit 4 includes a through hole 401 at the top of the air inlet chamber 3, which connects the air inlet chamber 3 to the dehumidification chamber 2. A mounting plate 402 with a vent is horizontally fixed inside the through hole 401, and an exhaust fan 403 with a motor is horizontally fixed on the mounting plate 402. By controlling the exhaust fan 403 to operate, the gas in the air inlet chamber 3 is discharged into the dehumidification chamber 2 through the through hole 401, thereby blowing away the moisture on the fiber filaments at the bottom of the dehumidification chamber 2. An exhaust pipe 404 is horizontally fixed inside the dehumidification chamber 2 above the through hole 401, and an impeller 405 is rotatably installed inside the exhaust pipe 404. A first motor 406 driving the corresponding impeller 405 is fixedly installed on the side of the device body 1. The bottom end of the exhaust pipe 404 is vertically connected to a first air inlet pipe 407. The air inlet of the first air inlet pipe 407 is located directly above the through hole 401. The first air inlet pipe 407 has a long strip structure, and its air inlet abuts against the fiber filaments. The length direction of the first air inlet pipe 407 is perpendicular to the length direction of the device body 1. The first motor 406 is controlled to work, driving the impeller 405 to rotate, thereby adsorbing the fiber filaments through the first air inlet pipe 407. The long strip structure and the slender air inlet of the first air inlet pipe 407 increase the adsorption intensity, thereby directly sucking away the moisture blown out by the exhaust fan 403.

[0036] The top end of the exhaust pipe 404 is connected to an exhaust pipe 408. A dryer 409 is provided on one side of the equipment body 1. The dryer 409 is a mature existing technology, and its working principle and structure are not the focus of this application, so they will not be described in detail here. The air outlet of the exhaust pipe 408 passes through the top end of the equipment body 1 and is connected to the air inlet of the dryer 409. The air outlet of the dryer 409 is connected to an air outlet pipe 410, which has multiple air outlets, each of which is connected to a corresponding air inlet chamber 3. Moisture and air in the exhaust pipe 404 are discharged into the interior of the dryer 409 through the exhaust pipe 408. After being processed by the dryer 409, the air is discharged into the interior of the air inlet chamber 3 through the air outlet pipe 410, forming an air circulation. Heating wires 411 are horizontally fixed on multiple mounting plates 402 on the side of the discharge port 7. The exhaust pipe 404 at the feed inlet 6 only extracts air from the fiber filaments, removing most of the moisture. Then, the heating wire 411 on the rear assembly plate 402 is controlled to operate, blowing hot air onto the fiber filaments for drying.

[0037] To achieve the wiping and dehumidification of the fiber filaments. In this embodiment, see... Figures 2-5 The dehumidification chamber 2 is further equipped with a wiping unit 5 for contact dehumidification of the fiber filaments. Multiple wiping units 5 are provided, each located between two corresponding exhaust pipes 404. Each wiping unit 5 includes a horizontally positioned lifting plate 509 inside the dust removal chamber between every two through holes 401. At least one guide rod 501 is vertically fixed to the top of the lifting plate 509, with its top end penetrating the top of the equipment body 1 and extending outwards. A lead screw 502 is rotatably mounted at the middle of the top of the lifting plate 509, its top end penetrating the top of the equipment body 1 and extending outwards, and is threadedly connected to the top of the equipment body 1. Rotating the lead screw 502 causes the lifting plate 509 to move up and down along the equipment body 1, guided by the guide rods 501 during this process.

[0038] The lifting plate 509 has a U-shaped structure with its opening facing downwards. At least one rotating roller 503 is horizontally rotatably mounted at the middle of the two arms of the lifting plate 509. A sponge ring 504, which contacts the fiber filaments, is sleeved on the rotating roller 503. The lifting plate 509 moves up and down until the sponge ring 504 comes into contact with the fiber filaments. The end of the rotating roller 503 extends outwards through the side of the lifting plate 509. A second motor 505 is fixedly mounted on the lifting plate 509. Both the output end of the second motor 505 and the end of the rotating roller 503 are fixedly mounted with pulleys 506, and belts 507 are sleeved on the two pulleys 506. By controlling the second motor 505 to work, the rotating roller 503 is driven to rotate through the pulleys 506 and belts 507, thereby wiping the fiber filaments, absorbing residual moisture, improving cleanliness and drying efficiency, and thus achieving a more thorough and efficient dehumidification process. Each of the multiple exhaust pipes 404 on one side of the discharge port 7 is connected to a second air inlet pipe 508, and the air inlet of the second air inlet pipe 508 abuts against the sponge ring 504 of the corresponding rotating roller 503. The second air inlet pipe 508 absorbs the moisture wiped off the sponge ring 504.

[0039] The method of using the rapid dehumidification treatment equipment for chemical fiber molding of this utility model is as follows: First, rotate the lead screw 502 to move the lifting plate 509 up and down along the equipment body 1, and guide it through the guide rod 501 during this process. Continue until the sponge ring 504 comes into contact with the fiber filament. The fiber filament enters the dehumidification chamber 2 through the feed inlet 6. During this process, control the exhaust fan 403 to operate, discharging the gas in the air inlet chamber 3 into the dehumidification chamber 2 through the through hole 401, thereby blowing away the moisture on the fiber filament at the bottom of the dehumidification chamber 2. Control the first motor 406 to operate, driving the impeller 405 to rotate, thereby adsorbing the fiber filament through the first air inlet pipe 407. The long strip structure of the first air inlet pipe 407 increases the adsorption intensity, thus directly sucking away the moisture blown out by the exhaust fan 403. Moisture and air in the exhaust duct 404 are discharged into the dryer 409 through the exhaust duct 408. After being processed by the dryer 409, the air is discharged into the air inlet chamber 3 through the air outlet duct 410, forming an air circulation. During this process, the exhaust duct 404 at the feed inlet 6 only extracts air from the fiber filaments, removing most of the moisture. Then, the heating wire 411 on the rear assembly plate 402 is controlled to operate, blowing hot air onto the fiber filaments for drying.

[0040] During the gas drying process, the second motor 505 is controlled to operate, driving the roller 503 to rotate via the pulley 506 and belt 507. This wipes the fiber filaments, absorbs residual moisture, and improves cleanliness and drying efficiency, thus achieving a more thorough and efficient dehumidification process. The moisture wiped off the sponge ring 504 is then absorbed through the second air inlet duct 508. The dehumidified fiber filaments are discharged from the outlet 7.
