Description

Technical Field

[0001] This utility model belongs to the field of spinneret technology, and specifically relates to a quick-change device for irregularly shaped spinnerets. Background Technology

[0002] Spinnerets are core components in chemical fiber production. Their core function is to transform polymer melts or solutions into fine streams with specific cross-sections through micropores, which are then solidified into fibers by a coagulation medium. Some spinnerets have holes that differ from the round holes of traditional spinnerets; these are called irregularly shaped spinnerets.

[0003] Currently, Chinese utility model patent CN215856479U discloses a replaceable spinneret for easy positioning and splicing. Existing irregularly shaped spinnerets are generally installed using a bolted method, allowing for disassembly, repair, or replacement. However, replacement requires unscrewing and re-screwing each screw individually, making the process cumbersome and affecting the efficiency of spinneret replacement. Furthermore, existing irregularly shaped spinnerets primarily shape the textile liquid by blowing air from the side of the spinneret orifice before the filaments exit the spinneret. However, this method requires precise control of the hot air volume; improper airflow can cause the filaments to be skewed before exiting the orifice, or even lead to yarn breakage, thus reducing the shaping effect and fiber quality. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change device for irregularly shaped spinnerets, which has the advantages of facilitating the rapid replacement of irregularly shaped spinnerets and avoiding direct contact of hot air with the fiber filaments, thereby improving the shaping effect of the fiber filaments before they are ejected.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-change device for irregularly shaped spinnerets, including a mounting base, a spinneret body slidably connected inside the mounting base, a first gear rotatably connected inside the inner wall of the mounting base, a threaded rod that is threadedly inserted into the spinneret body welded to one end of the first gear near the spinneret body, an annular plate rotatably connected to the mounting base sleeved on the surface of the first gear, an inner annular rack that meshes with the first gear welded to the inner surface of the annular plate, an outer annular rack welded to the outer surface of the annular plate, and a second gear that meshes with the outer annular rack rotatably connected to the other side of the inner wall of the mounting base.

[0006] By employing the above technical solution, the second gear meshes with the outer ring rack on the surface of the annular plate. This outer ring rack then meshes with the first gear via the inner ring rack, uniformly driving all the threaded rods inside the mounting base to engage with the threads of the spinneret body. This allows for quick installation and removal of the spinneret body from the mounting base, eliminating the need to manually tighten each bolt, thus improving efficiency. High-temperature hot air is blown into the hot air duct through the hot air inlet. Simultaneously, the heat absorption cylinder blocks the hot air and absorbs its heat, transferring it to the textile liquid for plasticization. This improves the shaping effect of the fibers before they are ejected, prevents direct contact between hot air and the fibers, and enhances the practicality of the spinneret.

[0007] The present invention is further configured such that: a hot air inlet is provided at the bottom of the mounting base; a hot air groove communicating with the hot air inlet is provided inside the spinneret body; a spinneret hole is also provided inside the spinneret body; and a heat-absorbing cylinder is welded to one end of the surface of the spinneret hole inside the hot air groove.

[0008] By adopting the above technical solution, the shaping effect of the fiber filaments before they are ejected can be improved, hot air can be prevented from directly contacting the fiber filaments, and the practicality of the spinneret can be improved.

[0009] The present invention is further configured such that: a liquid inlet is provided at one end of the mounting base away from the spinneret body, and a liquid distribution groove communicating with the inside of the spinneret hole is provided on the side of the liquid inlet near the spinneret body.

[0010] By adopting the above technical solution, textile filament is injected into the interior of the mounting base through the filament inlet, so that the textile filament can be evenly introduced into each spinneret through the uniform distribution tank, thereby improving the spinning effect.

[0011] The present invention is further configured such that a sealing ring, which is used in conjunction with the spinneret body, is snapped onto the inner surface of the mounting base.

[0012] By adopting the above technical solution, the sealing performance of the spinneret body after it is installed inside the mounting base is improved, preventing hot air and textile liquid from leaking out from the gaps.

[0013] The present invention is further configured such that: a handwheel that is rotatably connected to the mounting base is welded to the side of the second gear near the spinneret body.

[0014] Using the above technical solution, the second gear can be rotated inside the mounting base by turning the handwheel, thereby meshing and transmitting power with the outer ring rack.

[0015] The present invention is further configured such that: both the inner and outer surfaces of the annular plate are slidably connected to ball bearings that are rotatably connected to the mounting base.

[0016] The above technical solution is used to support the rotation of the annular plate inside the mounting base and reduce the frictional force of rotation.

[0017] The present invention is further configured such that: the bottom of the mounting base is provided with a hot air outlet that is connected to the end of the hot air groove away from the hot air inlet.

[0018] The above technical solution is used to discharge the hot air inside the hot air duct, so that hot air can continuously enter the hot air duct through the hot air inlet.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By rotating the second gear and engaging it with the outer ring rack on the surface of the ring plate, the outer ring rack engages again with the first gear through the inner ring rack, thereby uniformly driving all the threaded rods inside the mounting base to mesh with the threads of the spinneret body. This allows the spinneret body to be quickly installed and removed from the mounting base, eliminating the need to twist the bolts one by one, thus improving efficiency.

[0021] 2. High-temperature hot air is blown into the hot air duct through the hot air inlet. At the same time, the heat absorption cylinder blocks the hot air and absorbs its heat, transferring it to the spinning solution to plasticize it. This improves the shaping effect of the fibers before they are ejected, avoids direct contact between hot air and the fibers, and enhances the practicality of the spinneret.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A quick-change device for irregularly shaped spinnerets includes a mounting base 1. A spinneret body 2 is slidably connected inside the mounting base 1. A first gear 3 is rotatably connected inside the inner wall of the mounting base 1. A threaded rod 4, threaded into the spinneret body 2, is welded to one end of the first gear 3 near the spinneret body 2. An annular plate 5, rotatably connected to the mounting base 1, is fitted on the surface of the first gear 3. An inner ring rack 6, meshing with the first gear 3, is welded to the inner surface of the annular plate 5. An outer ring rack 7 is welded to the outer surface of the annular plate 5. A second gear 8, meshing with the outer ring rack 7, is rotatably connected to the other side of the inner wall of the mounting base 1. By rotating the second gear 8, it meshes with the outer ring rack 7 on the surface of the annular plate 5. After the outer ring rack 7 meshes with the first gear 3 again through the inner ring rack 6, all the threaded rods 4 inside the mounting base 1 are driven to engage with the threads of the spinneret body 2. This allows the spinneret body 2 to be quickly installed and removed from the mounting base 1, eliminating the need to manually tighten each bolt and improving efficiency.

[0030] refer to Figure 2 , Figure 4 The inner surface of the mounting base 1 is fitted with a sealing ring 17 that mates with the spinneret body 2. This improves the sealing performance of the spinneret body 2 after it is installed inside the mounting base 1, preventing hot air and textile liquid from leaking out through gaps.

[0031] refer to Figure 1 A handwheel 16, which is rotatably connected to the mounting base 1, is welded to the side of the second gear 8 near the spinneret body 2. By rotating the handwheel 16, the second gear 8 can be driven to rotate inside the mounting base 1, thereby meshing and transmitting power with the outer ring rack 7.

[0032] refer to Figure 2 , Figure 4 Both the inner and outer surfaces of the annular plate 5 are slidably connected to ball bearings 18, which are rotatably connected to the mounting base 1. These ball bearings support the rotation of the annular plate 5 within the mounting base 1, reducing rotational friction.

[0033] Brief description of the usage process: By sliding the spinneret body 2 into the mounting base 1 and rotating the second gear 8 to mesh with the outer ring rack 7, the ring plate 5 rotates inside the mounting base 1. Then, the ring plate 5 drives the inner ring rack 6 to mesh with the first gear 3, thereby driving all the first gears 3 inside the mounting base 1 to rotate synchronously in the same direction, so that the threaded rod 4 can uniformly engage with the threaded spinneret body 2, quickly installing the spinneret body 2 inside the mounting base 1. At the same time, by rotating the second gear 8 in the opposite direction, the threaded rod 4 can be uniformly rotated out of the spinneret body 2 in the opposite direction, allowing the spinneret body 2 to be quickly removed from the mounting base 1.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2 A quick-change device for irregularly shaped spinnerets is disclosed. A hot air inlet 9 is provided at the bottom of the mounting base 1. A hot air channel 11 communicating with the hot air inlet 9 is provided inside the spinneret body 2. Spinning holes 10 are also provided inside the spinneret body 2. A heat-absorbing cylinder 12 is welded to one end of the spinning hole 10 inside the hot air channel 11. High-temperature hot air is blown into the hot air channel 11 through the hot air inlet 9. Simultaneously, the heat-absorbing cylinder 12 blocks the hot air and absorbs its heat, transferring it to the textile liquid for plasticization. This improves the shaping effect of the fibers before they are ejected, avoids direct contact between hot air and the fibers, and enhances the practicality of the spinneret.

[0036] refer to Figure 2 The mounting base 1 has a filament inlet 14 at the end away from the spinneret body 2. A uniform distribution tank 15, communicating with the inside of the spinneret holes 10, is located on the side of the filament inlet 14 closest to the spinneret body 2. The filament is injected into the mounting base 1 through the filament inlet 14, allowing it to evenly enter each spinneret hole 10 through the uniform distribution tank 15, thus improving the spinning effect.

[0037] refer to Figure 1 , Figure 2 The bottom of the mounting base 1 has a hot air outlet 13 that is connected to the end of the hot air duct 11 away from the hot air inlet 9. This outlet is used to discharge the hot air inside the hot air duct 11, so that hot air can continuously enter the hot air duct 11 through the hot air inlet 9.

[0038] Brief description of the usage process: Textile liquid is injected into the spinneret holes 10 inside the spinneret body 2, causing the textile liquid to flow forward inside the spinneret holes 10. Then, high-temperature hot air is blown into the hot air duct 11 through the hot air inlet 9, filling the hot air duct 11. Then, the airflow is blocked by the heat absorption cylinder 12, which absorbs the heat of the hot air and transfers it to the textile liquid inside, causing it to be plasticized at high temperature before being ejected from the spinneret holes 10.
