Description

Technical Field

[0001] This utility model relates to the field of air cooling technology, and in particular to a combined melt-spun filament high-efficiency double-sided air blowing cooling structure. Background Technology

[0002] Melt-spun filaments, also known as melt spinning, are produced by extruding a polymer spinning melt, such as PA or PE, from the spinneret of a spinning machine. The extruded melt stream is then cooled and stretched by air blowing, and finally solidified into filaments. These filaments are used as the precursor yarn for subsequent spinning or for other purposes. After the melt-spun filaments are processed, they need to be cooled in a timely manner.

[0003] The existing technology has the following problems: Although double-sided blowing provides more uniform cooling than single-sided side blowing, uneven airflow distribution can still occur in certain special cases, such as spinning irregularly shaped fibers or high-speed spinning. This is because the airflow may be affected by factors such as the shape and arrangement of the fiber bundle and the structure of the equipment, resulting in differences in the cooling effect of different parts of the fiber bundle. Utility Model Content

[0004] This invention provides a combined, high-efficiency, double-sided blowing cooling structure for melt-spun filaments to solve the problems mentioned in the background art.

The spacing adjustment component includes a stepper motor, which is fixedly installed at the top center of the air guide frame. The drive end of the stepper motor is fixedly connected to a connecting gear, which is rotatably connected inside the air guide frame. Both sides of the stepper motor are meshed with transmission gear plates, which are symmetrically arranged and slidably connected inside the air guide frame.

[0006] Preferably, the spacing adjustment assembly further includes a pair of suspension members, the two suspension members on both sides are fixedly connected to the top of the two transmission tooth plates, and guide grooves are provided on both sides of the top of the air guide frame at the positions corresponding to the transmission tooth plates, and the two suspension members on both sides are slidably connected to the top of the two guide grooves.

[0007] Preferably, movable guide rails are fixedly installed on both sides of the inner wall of the air guide frame, and sliding members are slidably connected to both sides of the outer wall of the movable guide rails. The sliding members are respectively fixedly connected to the bottom of the two transmission gear plates.

[0008] Preferably, air blowing pipes are fixedly installed on the inner sides of the sliding members on both sides, and flexible hoses are provided through the bottom of the air blowing pipes on both sides. An air inlet hood is fixedly installed on the lower inner wall of the air guide frame, and a filter screen is fixedly connected at the bottom center of the air inlet hood.

[0009] Preferably, a collection cover is provided at the top of the air inlet hood, directly above the filter screen. A fan is fixedly installed inside the collection cover, and the ends of the hoses on both sides away from the blower pipe both penetrate and extend into the interior of the collection cover.

[0010] Preferably, the support and adjustment assembly includes a pair of hollow tubes, with the hollow tubes on both sides fixedly installed in the middle of the inner wall of the sliding member on both sides. The inner wall of the hollow tubes on both sides is sleeved with an I-shaped plate and slidably connected to the outer wall of the I-shaped plate. A connecting spring is fixedly connected inside the hollow tubes on both sides, and the other end of the connecting springs on both sides is fixedly connected to the I-shaped plate.

[0011] Preferably, a turntable is rotatably connected to the top of the I-shaped plate, and a take-up drum is fixedly connected to the top of the turntable. The end of the take-up drum away from the turntable passes through the air guide frame and is fixedly connected to the connecting gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a combined high-efficiency double-sided blowing cooling structure for melt-spun filaments. The core of the high-efficiency double-sided blowing cooling structure for melt-spun filaments is installed on the spinning box. The distance between the two double-sided air supply mechanisms is set to adjust the airflow path around the filament bundle, thereby compensating for the cooling differences caused by the shape and arrangement of the filament bundle. When spinning finer or easily sticky filament bundles, the two sets of mechanisms can be appropriately spaced apart to reduce the squeezing force of the airflow on the filament bundle and avoid the uncured filament bundles from sticking together and forming strands. When spinning filament bundles that require stable tension, the two sets of mechanisms can be appropriately close together to optimize the airflow direction, prevent the filament bundle from expanding excessively, and reduce the probability of breakage.

[0013] 2. This utility model provides a combined high-efficiency double-sided blowing cooling structure for melt-spun filaments. The blowing cooling area is designed to allow for synchronous reversal of the direction of the wound melt-spun filaments as the spacing of the blowing mechanism is adjusted. This ensures that all areas of the melt-spun filaments are cooled by air blowing. When spinning coarse denier filaments or multiple parallel filament bundles, increasing the spacing while reversing the direction allows the airflow to penetrate deeper into the filament bundle, avoiding cooling lag caused by air entrapment in the central area. When spinning fine denier filaments or easily drifting filament bundles, decreasing the spacing in conjunction with a small directional adjustment can enhance local air pressure while offsetting the compression of the filament bundle by changing the direction, reducing the risk of filament bundling.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 - Figure 8 As shown, a combined melt-spun filament high-efficiency double-sided blowing cooling structure includes an air guide frame 1, a spacing adjustment component is provided in the middle of the air guide frame 1, and a support and direction adjustment component is provided inside the air guide frame 1. The spacing adjustment component includes a stepper motor 21, which is configured to rotate alternately in both directions of 180 degrees. It is fixedly installed at the top center of the air guide frame 1. The drive end of the stepper motor 21 is fixedly connected to a connecting gear 22, which is rotatably connected inside the air guide frame 1. Both sides of the stepper motor 21 are meshed with transmission gear plates 23, which are symmetrically arranged and slidably connected inside the air guide frame 1.

[0018] It should be noted that the core of the high-efficiency double-sided blowing cooling structure for melt-spun filament is installed on the spinning box. The stepper motor 21 drives the connecting gear 22 to rotate in either the forward or reverse direction, thereby causing the transmission gear plates 23 on both sides to expand or move closer to the inside of the air guide frame 1.

[0019] like Figure 2 - Figure 5 As shown, the spacing adjustment assembly also includes a pair of suspension members 25. The two suspension members 25 are fixedly connected to the top of the two transmission tooth plates 23 respectively. The top two sides of the air guide frame 1 are provided with guide grooves 24 corresponding to the positions of the transmission tooth plates 23. The two suspension members 25 are slidably connected to the top of the two guide grooves 24 respectively.

[0020] It should be noted that the transmission gear plates 23 on both sides slide within the guide grooves 24 on both sides via the suspension components 25 on both sides.

[0021] like Figure 2 , Figure 5 and Figure 7 As shown, movable guide rails 26 are fixedly installed on both sides of the inner wall of the air guide frame 1, and sliding parts 27 are slidably connected to both sides of the outer wall of the movable guide rails 26. The sliding parts 27 are fixedly connected to the bottom of the transmission gear plates 23 on both sides respectively.

[0022] It should be noted that as the transmission gear plates 23 on both sides move, they further drive the sliding parts 27 on both sides to slide along the outer wall of the moving guide rail 26.

[0023] like Figure 2 - Figure 4 As shown, air blowing pipes 28 are fixedly installed on the inner sides of the sliding parts 27 on both sides. Flexible hoses 213 are provided through the bottom of the air blowing pipes 28 on both sides. An air inlet cover 29 is fixedly installed on the lower inner wall of the air guide frame 1. A filter screen 211 is fixedly connected at the bottom center of the air inlet cover 29. A collection cover 210 is provided on the top of the air inlet cover 29 directly above the filter screen 211. A fan 212 is fixedly installed inside the collection cover 210. The ends of the flexible hoses 213 on both sides that are away from the air blowing pipes 28 are both passed through and extended into the inside of the collection cover 210.

[0024] It should be noted that the two side air blowers 28 move synchronously with the two side sliding parts 27. This allows for adjustment of the distance between them. The fan 212 draws air from the outside of the air inlet hood 29, filters it through the filter screen 211, and then enters the interior of the air inlet hood 29. After being collected at the collecting cover 210, the air is transported along the two side hoses 213 to the interior of the two side air blowers 28.

[0025] like Figure 4 and Figure 8As shown, the support and adjustment assembly includes a pair of hollow tubes 31. The hollow tubes 31 on both sides are fixedly installed in the middle of the inner wall of the sliding member 27 on both sides. The inner wall of the hollow tubes 31 on both sides is sleeved with an I-shaped plate 32 and slidably connected to the outer wall of the I-shaped plate 32. The interior of the hollow tubes 31 on both sides is fixedly connected with a connecting spring 33. The other end of the connecting spring 33 on both sides is fixedly connected to the I-shaped plate 32.

[0026] It should be noted that as the sliding parts 27 on both sides move, they further drive the hollow tubes 31 on both sides to slide close to or away from the outer walls of both ends of the I-shaped plate 32, and become more stable with the assistance of the connecting spring 33.

[0027] like Figure 4 As shown, a turntable 34 is rotatably connected to the top of the I-shaped plate 32, and a take-up drum 35 is fixedly connected to the top of the turntable 34. The end of the take-up drum 35 away from the turntable 34 passes through the air guide frame 1 and is fixedly connected to the connecting gear 22. The turntable 34, the take-up drum 35, the connecting gear 22, and the stepper motor 21 are located on the same straight line.

[0028] It should be noted that the turntable 34 rotates synchronously with the connecting gear 22 via the take-up drum 35, so that the melt-spun filaments at various positions on the outer wall of the take-up drum 35 can be cooled by the airflow. As the spacing of the blower mechanism is adjusted, the direction of the melt-spun filaments being taken up is also reversed. When spinning coarse denier filaments or multiple parallel filament bundles, the spacing is increased while the direction is reversed, which allows the airflow to penetrate deeper into the filament bundle and avoids the cooling lag caused by the wind entrapment in the central area. When spinning fine denier filaments or easily drifting filament bundles, the spacing is decreased in combination with a small directional adjustment, which can strengthen the local air pressure while offsetting the compression of the filament bundle by the change of direction, reducing the risk of filament bundling.

[0029] The working principle of this utility model: First, the processed melt-spun filament is wound onto the outer wall of the take-up drum 35, and the core of the high-efficiency double-sided blowing cooling structure of the melt-spun filament is installed on the spinning box. The stepper motor 21 drives the connecting gear 22 to rotate in either the forward or reverse direction, which in turn drives the two transmission gear plates 23 to expand or move closer to the inside of the air guide frame 1. The two transmission gear plates 23 slide in the inside of the two guide grooves 24 through the two suspension pieces 25. As the two transmission gear plates 23 move, the two sliding pieces 27 are further driven to slide along the outer wall of the moving guide rail 26. The two side air blowing pipes 28 move synchronously with the two side sliding parts 27. This allows for adjustment of the distance between them. The fan 212 draws air from the outside of the air inlet hood 29, filters it through the filter screen 211, and then enters the interior of the air inlet hood 29. The air gathers at the collecting cover 210 and is then transported along the two side hoses 213 to the interior of the two side air blowing pipes 28. As the two side sliding parts 27 move, they further drive the two side hollow pipes 31 to slide close to or away from each other along the outer walls of the two ends of the I-shaped plate 32, and become more stable with the assistance of the connecting spring 33. The turntable 34 rotates synchronously with the connecting gear 22 via the take-up drum 35, so that the melt-spun filaments at various positions on the outer wall of the take-up drum 35 can be cooled by the wind. The direction of the melt-spun filaments being wound is reversed synchronously with the adjustment of the distance between the blower components. When spinning coarse denier filaments or multiple parallel filament bundles, increasing the spacing while changing the direction allows the airflow to penetrate deeper into the filament bundle, preventing cooling lag in the central area due to air entrapment. When spinning fine denier filaments or easily drifting filament bundles, decreasing the spacing in conjunction with small directional adjustments can enhance local air pressure while offsetting the airflow's compression of the filament bundle through directional changes, reducing the risk of filament bundling.
