Description

Technical Field

[0001] This utility model belongs to the field of textile tooling technology, specifically relating to an airflow guiding mechanism for a side-blowing rapid cooling device. Background Technology

[0002] In melt spinning processes, such as the production of synthetic fibers like polyester and nylon, the polymer melt is extruded from the spinneret to form nascent filament bundles. These filament bundles are in a molten state and must be rapidly and uniformly cooled and solidified by a cooling air blowing device to obtain good mechanical properties and stable fineness.

[0003] Side-blowing quenching devices are commonly used cooling equipment. They use air vents located on one or both sides of the fiber bundle to blow cooling air (usually clean air that has been conditioned for temperature and humidity) vertically along the path of the fiber bundle, achieving uniform cooling. The uniformity and stability of the airflow distribution directly determine the cooling effect of the fiber bundle, and thus affect the quality of the fiber.

[0004] Traditional side-blowing windows typically use perforated plates or wire mesh to regulate airflow, but these methods have the following problems in practical applications:

[0005] 1. Insufficient airflow uniformity: Although the perforated plate can play a certain role in rectifying the airflow, for large-area air windows, there may still be differences in wind speed and air pressure at different positions on the air outlet surface, resulting in uneven cooling of the filament bundles and easily causing problems such as uneven strands and breakage.

[0006] 2. Poor airflow direction control: Some airflow may not be blown perpendicularly to the filament bundle, resulting in a certain angular deviation, which weakens the effective cooling intensity and may cause the filament bundle to vibrate.

[0007] 3. Fixed structure, not easy to disassemble, replace and clean: After long-term use, it is inconvenient to disassemble and clean, and when parts need to be replaced, the disassembly time is long. Summary of the Invention

[0008] To address the problems mentioned in the background section, the purpose of this invention is to provide an airflow guiding mechanism for a side-blowing quenching device.

[0009] This utility model discloses an airflow guiding mechanism for a side-blowing rapid cooling device, comprising a blowing device, a right-angle elbow, an air outlet duct, and a modular rectifier mechanism. The air outlet of the blowing device is fixedly connected to one end of the right-angle elbow via bolts, and the other end of the elbow is fixedly connected to the air outlet duct via bolts. The modular rectifier mechanism is inserted into the air outlet duct and fixedly installed on it via bolts. The modular rectifier mechanism includes a rectifier outer casing, an upper sealing plate, partition plates, a rectifier plate body, a fixed guide plate, an adjustable guide plate, an air outlet plate, and locking bolts. The top of the rectifier outer casing is welded to the upper sealing plate, and the four corners of the upper sealing plate are sealed to the air outlet duct via locking bolts. Several partition plates are uniformly and sealed inside the rectifier outer casing, dividing it into several rectifier cavities. From left to right, a rectifier plate body, a fixed guide plate, and an adjustable guide plate are fixedly installed in each of the rectifier cavities. An air outlet plate is fixedly installed on the right end face of the rectifier outer casing.

[0010] As a preferred embodiment: the air outlet duct body is provided with an air outlet channel inside, the upper end face of the air outlet duct body is provided with a plug groove, the plug groove is connected to the air outlet channel, and a fixed flange is welded to the left end of the air outlet duct body.

[0011] As a preferred embodiment, a sealing gasket is connected to the bottom of the upper sealing plate, and the sealing gasket is sealed to the air outlet duct body.

[0012] As a preferred embodiment, the rectifier plate has several tapered holes evenly distributed on it.

[0013] As a preferred embodiment, the upper surface of the fixed guide plate is arc-shaped.

[0014] As a preferred embodiment: the adjustable guide vane includes a rotating shaft, a guide vane, a pulley, a belt, and an adjusting motor; guide vanes are symmetrically fixedly connected to several rotating shafts, pulleys are fixedly connected to one end of several rotating shafts, several pulleys are connected by a belt, and the rotating shaft of the adjusting motor is connected to one pulley.

[0015] As a preferred embodiment, the air outlet plate is provided with several air outlet holes evenly spaced.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The uniformity and controllability of the airflow are achieved through the coordinated operation of the blowing device, right-angle elbow, air outlet pipe, and modular rectifier mechanism, resulting in uniform cooling of the filament bundle. Simultaneously, it facilitates disassembly, cleaning, and replacement, saving time. Specific advantages include:

[0017] I. This utility model achieves the rectification of cooling air through the rectifier plate, and at the same time achieves the primary guidance through the fixed guide plate, so that the airflow is initially sorted into a more parallel and uniform airflow.

[0038] Specific implementation method one: Combining Figures 1 to 7 The following describes this specific embodiment. This embodiment uses a modular rectification mechanism to achieve rapid installation and disassembly, while also rectifying the cooling air so that the cooling air can be blown evenly onto the vertical filament bundle. The specific technical solution adopted is as follows: it includes a blower device 1, a right-angle elbow 2, an air outlet duct 3, and a modular rectification mechanism 4. The air outlet of the blower device 1 is fixedly connected to one end of the right-angle elbow 2 by bolts, and the other end of the right-angle elbow 2 is fixedly connected to the air outlet duct 3 by bolts. The air outlet duct 3 can achieve rapid air outlet. The modular rectification mechanism 4 is inserted into the air outlet duct 3 and fixedly installed on the air outlet duct 3 by bolts. The modular rectification mechanism 4 can achieve air cooling treatment, so that the air can dissipate heat evenly to the filament bundle.

[0039] Combination Figure 3The illustration shows this specific embodiment, which uses a modular rectifier mechanism to rectify the cooling air, making the cooling air controllable. The specific technical solution is as follows: The modular rectifier mechanism 4 includes a rectifier outer casing 4-1, an upper sealing plate 4-2, a partition plate 4-3, a rectifier plate body 4-4, a fixed guide plate 4-5, an adjustable guide plate 4-6, an air outlet plate 4-7, and locking bolts 4-8. The top of the rectifier outer casing 4-1 is welded to the upper sealing plate 4-2, which can seal with the air outlet duct body 3. The rectifier outer casing 4-1 can be quickly installed and disassembled. The four corners of the upper sealing plate 4-2 are sealed to the air outlet duct body 3 using locking bolts 4-8. The interior of the rectifier outer casing 4-1 is uniformly sealed. Several partition plates 4-3 are installed, dividing the rectifier outer box 4-1 into several rectifier cavities 4-31. The rectifier cavities 4-31 can rectify the airflow. From left to right, rectifier plate 4-4, fixed guide plate 4-5, and adjustable guide plate 4-6 are fixedly installed in the rectifier cavities 4-31. The rectifier plate 4-4 can initially sort the airflow into a more parallel and uniform airflow. The fixed guide plate 4-5 realizes the parallel guidance of the airflow. At the same time, the adjustable guide plate 4-6 can realize the angle adjustment. The adjustment range is usually within ±15°. An air outlet plate 4-7 is fixedly installed on the right end face of the rectifier outer box 4-1. The air outlet plate 4-7 can smooth out any unevenness that may exist in the airflow after the angle adjustment.

[0040] The working principle of this specific embodiment is as follows: After the cooling air from the blowing device 1 is initially distributed in the side blowing box, it first passes through the rectifier plate 4-4 of the rectifier outer box 4-1 for preliminary rectification, making the airflow smooth and vertical. Then, the airflow enters the adjustable guide plate 4-6. By adjusting the tilt angle of the guide plate, the overall airflow direction can be finely adjusted to adapt to the special requirements of the filament position or process. Finally, the airflow passes through the air outlet plate 4-7 for final fine rectification, eliminating any tiny eddies generated by the guide plate, and ensuring that the airflow blown towards the filament is highly uniform, stable, and precisely perpendicular to the plane of the filament.

[0041] Specific Implementation Method Two: Combining Figure 2 The following describes this specific embodiment, which is a further limitation of the first specific embodiment. This specific embodiment achieves the rapid installation of the modular rectifier mechanism 4 through the air outlet duct body 3. The specific technical solution adopted is as follows: The air outlet duct body 3 is provided with an air outlet channel 3-1 inside. The upper end face of the air outlet duct body 3 is provided with a plug groove 3-2, which is connected to the air outlet channel 3-1. A fixed flange 3-3 is welded to the left end of the air outlet duct body 3. The fixed flange 3-3 can achieve a sealed connection with the right angle elbow 2. At the same time, the plug groove 3-2 can achieve the rapid plugging of the modular rectifier mechanism 4.

[0042] Specific implementation method three: Combining Figure 4 The illustration shows this specific embodiment, which is a further limitation of embodiment one or two. This specific embodiment achieves sealing with the air outlet duct body 3 through the upper sealing plate 4-2. Specifically, the following technical solution is adopted: a sealing gasket 4-21 is connected to the bottom of the upper sealing plate 4-2. The sealing gasket 4-21 seals with the air outlet duct body 3, and the sealing gasket 4-21 can achieve sealing with the air outlet duct body 3, thereby improving the sealing performance.

[0043] Specific implementation method four: Combination Figure 5 The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, or three. This specific embodiment achieves airflow rectification through the rectifier plate 4-4, specifically using the following technical solution: several conical holes 4-41 are evenly opened on the rectifier plate 4-4. The conical holes 4-41 can realize rapid rectification of the cooling air, so that the cooling air is initially combed into a more parallel and uniform airflow. The upper end face of the fixed guide plate 4-5 is arc-shaped, and the fixed guide plate 4-5 can realize the flatness and parallelism of the airflow. Several fixed guide plates 4-5 are equidistant and parallel.

[0044] Specific Implementation Method Five: Combining Figure 6 The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, three, or four. This specific embodiment uses an adjustable guide plate 4-6 to adjust the angle and fine-tune the overall airflow direction. The specific technical solution is as follows: The adjustable guide plate 4-6 includes a rotating shaft 4-61, a guide plate 4-62, a pulley 4-63, a belt 4-64, and an adjusting motor 4-65. Several rotating shafts 4-61 are symmetrically and fixedly connected to the guide plates 4-62. The rotating shafts 4-61 can drive the guide plates 4-62 to adjust the angle. One end of several rotating shafts 4-61 is fixedly connected to a pulley 4-63. Several pulleys 4-63 are connected by belts 4-64. The rotating shaft of the adjusting motor 4-65 is connected to a pulley 4-63. The adjusting motor 4-65 can drive the rotating shafts 4-61 to rotate, which facilitates simultaneous adjustment. The normal tilt angle adjustment range is -15° to +15° (with the vertical direction as the reference).

[0045] Specific Implementation Method Six: Combination Figure 7The illustration shows this specific embodiment, which is a further limitation of embodiment one, two, three, four or five. This specific embodiment uses an air outlet plate 4-7 to smooth out any unevenness that may exist in the airflow after angle adjustment. Specifically, the following technical solution is adopted: several air outlet holes 4-71 are evenly opened on the air outlet plate 4-7. The function of the air outlet plate 4-7 is to smooth out any unevenness that may exist in the airflow after angle adjustment, and ensure the quality of the final airflow.
