Technical Field
[0001] This utility model relates to the field of fiber setting technology, and in particular to a fiber setting device for hair product manufacturing. Background Technology
[0002] Hair products refer to accessories made from human hair, synthetic fibers, animal hair, etc. In the process of making wigs using synthetic fibers, it is necessary to perform a shaping operation on the synthetic fibers, which includes a heating step.
[0003] Existing technologies have certain shortcomings in fiber setting. For example, the fiber filaments in the spool contain broken filaments and impurities. If these are not removed during the heat setting process, the broken filaments and impurities will mix into the finished chemical fiber filaments, reducing their quality. Furthermore, chemical fiber filaments experience thermal expansion and contraction during heating, making it difficult to control the tension. Excessive tension can cause the filaments to break, while excessive looseness can cause them to drag. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a fiber setting device for hair product manufacturing, which has the advantages of removing impurities and broken fibers and elastically adjusting tension, thus solving the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a fiber setting device for hair product production, comprising a setting box, an inlet on one side of the setting box, and an outlet on the other side of the setting box, the inlet and outlet being symmetrically located, three heating rollers being uniformly rotatably mounted inside the setting box in a triangular array, a winding rod being mounted above the inlet on one side of the setting box, the winding rod being detachably mounted to the setting box, a brush block being fixedly mounted on one side of the setting box between the inlet and the winding rod, the brush block having bristles uniformly distributed on the side away from the setting box, tensioning devices being fixedly mounted between the inner walls of the inlet and outlet, and a steam device being fixedly mounted between the two inner walls of the setting box, the steam device being located between the heating rollers.
[0006] With the above structural design, the coil spring will drive the rotating rod to rotate inside the fixed cylinder due to the coiling force. When the rotating rod rotates in the vertical direction, it will make the chemical fiber filaments taut, which will have the effect of adjusting the tension. By setting up a steam device, it can achieve the advantages of fast heating speed, uniform heating and convenient adjustment, and avoid additional heat causing the surface of the chemical fiber filaments to char.
[0007] Preferably, the tensioning device includes a fixed cylinder, a rotating rod, and a coil spring. The fixed cylinder is fixedly installed between the two walls of the inlet and the outlet. The rotating rod is installed in a linear array and rotates uniformly inside the fixed cylinder. Coil springs are fixedly connected between the outer rings of the two ends of the rotating rod and the inner wall of the fixed cylinder.
[0008] With the above structural design, the chemical fiber filaments will expand thermally after being heated inside the shaping box, causing the original tension of the chemical fiber filaments to become unsuitable. Due to the change in tension, the coiling force of the coil spring will drive the side plate and the rotating wheel to change the angle, thus achieving adaptive adjustment.
[0009] Preferably, the outer wall of the fixed cylinder is provided with rotating grooves in a linear array, the outer ring of the rotating rod is fixedly installed with a side plate inside the rotating groove, and a rotating wheel is rotatably installed inside the side plate.
[0010] With the above structural setup, when the tension is too loose, the chemical fiber pushes against the position of the rotating wheel, and the rotating rod is forced to rotate inside the fixed cylinder, adjusting the tension of the chemical fiber to a relatively loose state.
[0011] Preferably, the steam device includes an upper steam pipe and a lower steam pipe. The upper steam pipe is located between the heating roller near the feed inlet and the middle heating roller, and the lower steam pipe is located between the heating roller near the discharge outlet and the middle heating roller. The upper steam pipe and the lower steam pipe are positioned opposite each other but not symmetrically.
[0012] With the above structural design, when the chemical fiber passes through the upper steam pipe, the steam heats the upper surface of the chemical fiber. When it passes through the lower steam pipe, the high-temperature steam sprayed from the lower steam pipe heats the lower surface of the chemical fiber, making it easier for the chemical fiber to be shaped during the reciprocating heating process.
[0013] Preferably, the upper and lower steaming pipes are provided with air vents evenly facing the direction of the chemical fiber filaments, and the air vents are evenly arranged in a linear array. A connecting pipe is fixedly connected between the upper and lower steaming pipes, and a support block is fixedly connected between the upper and lower steaming pipes and the inner wall of the shaping box.
[0014] With the above structural design, the support block is used to support the upper and lower steam pipes inside the shaping box. The lower steam pipe is connected to an external steam generator at its end, so that steam is continuously delivered to the upper and lower steam pipes through the lower steam pipe.
[0015] This utility model has the following advantages:
[0016] 1. This fiber setting device for hair product production removes impurities such as broken fibers by setting up brush blocks and tensioning devices. The fiber filaments are installed on the outer ring of the winding rod to shape the conveying path of the chemical fiber filaments. The chemical fiber filaments pass through the bristles of the brush block, and the broken fibers, sparse fibers, and dust impurities in the chemical fiber filaments are brushed away, so that the chemical fiber filaments entering the setting box are clean and free of impurities. The chemical fiber filaments are split into strands and passed through the outer ring of the rotating wheel, and then enter the interior of the setting box. They are evenly spread on the surface of the heating roller, pass around the surface of the heating roller, and are pulled out from the discharge port, which achieves the effect of removing impurities such as broken fibers.
[0017] 2. The fiber setting device for hair product production achieves elastic tension adjustment through the setting of a tensioning device, rotating rod, coil spring, and other structures. After the chemical fiber is heated, it will generate a thermal expansion effect, which changes the original tension of the chemical fiber. After the tension is changed, the coil spring drives the rotating rod inside the fixed cylinder to rotate, adjusting the tension of the chemical fiber. When the tension is too loose, the rotating rod inside the fixed cylinder rotates vertically to tighten the chemical fiber. When the tension is too tight, the chemical fiber pushes against the rotating wheel, forcing the rotating rod inside the fixed cylinder to rotate, adjusting the tension of the chemical fiber to a relatively loose state, thus achieving the effect of adaptive elastic tension adjustment.
[0018] 3. The fiber setting device for hair product production achieves uniform heating through the installation of a steam device, an upper steam pipe, and a lower steam pipe. When the chemical fiber filaments pass through the heating roller near the feed inlet, they are initially preheated. Then, they pass through the upper steam pipe, where steam is evenly sprayed onto the upper surface of the chemical fiber filaments through vent holes. After passing through the middle heating roller, the lower steam pipe sprays steam through vent holes to heat the lower surface of the chemical fiber filaments. Through the cooperation between the heating roller and the steam device, uniform heating of the upper and lower surfaces of the chemical fiber filaments is achieved, enabling the chemical fiber filaments to be set quickly. Furthermore, due to the position of the heating roller, the residence time of the chemical fiber filaments inside the setting box can be extended, achieving the effect of uniform heating and rapid setting.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-2 A fiber setting device for hair product manufacturing includes a setting box 1. The setting box 1 has an inlet 11 on one side and an outlet 12 on the other side, with the inlet 11 and outlet 12 symmetrically positioned. Heating rollers 13 are uniformly rotatably mounted inside the setting box 1. There are three heating rollers 13 arranged in a triangular array. A winding rod 2 is mounted above the inlet 11 on one side of the setting box 1. The winding rod 2 is detachable from the setting box 1. In use, the winding rod 2 is first detached from one side of the setting box 1, and then the spun hair is loaded onto the winding rod. The outer ring of 2 is then installed and can be used. A brush block 3 is fixedly installed on one side of the shaping box 1 between the feed inlet 11 and the winding rod 2. The brush block 3 has bristles evenly distributed on the side away from the shaping box 1. When the chemical fiber passes through the bristles of the brush block 3, it can remove broken and miscellaneous fibers that are not long enough, and at the same time brush away the dust and impurities in the chemical fiber. Tensioning devices 4 are fixedly installed between the inner walls of the feed inlet 11 and the discharge outlet 12. A steam device 5 is fixedly installed between the two inner walls of the shaping box 1. The steam device 5 is located between the heating rollers 13.
[0026] In practical applications, this device uses a tensioning device 4 and a fiber roll sleeve on the outer ring of the winding rod 2 to pass the fiber filaments through the bristles on one side of the brush block 3. The bristles remove broken and miscellaneous filaments that are not long enough, and also remove internal dust between the chemical fiber filaments, ensuring that the chemical fiber filaments entering the setting box 1 are of uniform length, clean, and dust-free. The chemical fiber filaments that have passed through the brush block 3 are split into strands, passed through the rotating wheel 46, and then evenly wound around the outer ring of the heating roller 13. Finally, they pass through the discharge port 12. The chemical fiber filaments should be evenly spread out when they are on the outer ring of the heating roller 13. In this state, by continuously heating the chemical fiber filaments, the chemical fiber filaments will produce a thermal expansion and contraction effect, which will change the tension of the chemical fiber filaments. After the tension of the chemical fiber filaments changes, the coil spring 43 will drive the rotating rod 42 to rotate inside the fixed cylinder 41 due to the coiling force. When the rotating rod 42 rotates in the vertical direction, it will make the chemical fiber filaments taut. If the chemical fiber filaments are too taut, the chemical fiber filaments will push the rotating wheel 46 upward, causing the rotating rod 42 to rotate in the horizontal direction inside the fixed cylinder 41. The tensioning device 4 is set to achieve an adaptive tension adjustment effect.
[0027] By setting up a steam device 5, when the chemical fiber filaments are continuously conveyed on the outer ring of the heating roller 13, the upper steam pipe 51 uniformly heats the upper surface of the chemical fiber filaments with steam. When the chemical fiber filaments are conveyed to the lower steam pipe 52, the lower steam pipe 52 heats the lower surface of the chemical fiber filaments. After passing through the shaping box 1, the chemical fiber filaments are continuously heated by the heating roller 13 and the steam device 5 with electricity and steam, so as to achieve uniform heating of the fiber filaments. By setting different heating methods, the advantages of fast heating speed, uniform heating, and convenient adjustment are achieved, and the additional heat is avoided from causing the surface of the chemical fiber filaments to char.
[0028] Please see Figures 1-3 The tensioning device 4 includes a fixed cylinder 41, a rotating rod 42, and a coil spring 43. The fixed cylinder 41 is fixedly installed between the two walls of the inlet 11 and the outlet 12. The rotating rod 42 is installed in a linear array and rotates evenly inside the fixed cylinder 41. The outer rings at both ends of the rotating rod 42 are fixedly connected to the inner wall of the fixed cylinder 41 with coil springs 43. The coil springs 43 provide elastic force between the rotating rod 42 and the fixed cylinder 41. When the rotating rod 42 tilts at too large an angle, the coil springs 43 will cause the rotating rod 42 to retract due to their own elastic force.
[0029] When the tension of the synthetic fiber is too high, the synthetic fiber will push the rotating wheel 46, forcing the rotating rod 42 to rotate laterally inside the fixed cylinder 41, thereby achieving adaptive elastic adjustment of the tension of the synthetic fiber. When the tension of the synthetic fiber is too loose, the coil spring 43 will contract elastically, causing the rotating rod 42 to rotate vertically inside the fixed cylinder 41, thus adjusting the tension of the synthetic fiber to a tight state.
[0030] Please see Figures 1-3 The outer wall of the fixed cylinder 41 has evenly spaced rotating grooves 44 arranged in a linear array. A side plate 45 is fixedly installed inside the rotating grooves 44 on the outer ring of the rotating rod 42. A rotating wheel 46 is rotatably installed inside the side plate 45. During use, the chemical fiber filaments pass through the bristles of the brush block 3 and enter the interior of the shaping box 1 from the outer ring of the rotating wheel 46. After being heated inside the shaping box 1, the chemical fiber filaments undergo thermal expansion, causing the original tension of the chemical fiber filaments to become unsuitable. Due to the change in tension, the rotating rod 42... The coiling force of the coil spring 43 causes the side plate 45 and the rotating wheel 46 to change angle. When the tension of the chemical fiber is too loose, the coil spring 43 will drive the rotating rod 42 to rotate at a vertical angle until the tension of the chemical fiber becomes tight. If the tension of the chemical fiber is too tight, the chemical fiber will drive the rotating rod 42 and the rotating wheel 46 to rotate at a horizontal angle within the inner ring of the fixed cylinder 41, so that the tension of the chemical fiber becomes a normal tight state, thus achieving the effect of elastically adjusting the tension of the chemical fiber.
[0031] Please see Figures 1-4The steam device 5 includes an upper steam pipe 51 and a lower steam pipe 52. The upper steam pipe 51 is located between the heating roller 13 near the inlet 11 and the middle heating roller 13. The lower steam pipe 52 is located between the heating roller 13 near the outlet 12 and the middle heating roller 13. The upper steam pipe 51 and the lower steam pipe 52 are positioned opposite each other but asymmetrically. Both the upper steam pipe 51 and the lower steam pipe 52 have evenly spaced ventilation holes facing the direction of the chemical fiber filaments. The ventilation holes are arranged in a linear array. During use, the chemical fiber filaments smoothly slide evenly between the outer rings of the heating rollers 13. The upper steam pipe 51 is located on the upper surface of the chemical fiber filaments during operation, and the lower steam pipe 52 is located on the lower surface of the chemical fiber filaments during operation. Because the heating roller 13 near the inlet 11 preheats the lower surface of the chemical fiber filaments first, the chemical fiber filaments pass through the upper steam pipe 51 and the lower steam pipe 52. When steaming tube 51 is used, steam is used to heat the upper surface of the chemical fiber. After passing through the middle heating roller 13, the upper surface of the chemical fiber is heated by the heating roller 13. Then, when passing through the lower steaming tube 52, the lower steaming tube 52 sprays high-temperature steam to heat the lower surface of the chemical fiber, making the chemical fiber easier to shape during the reciprocating heating process. A connecting pipe 53 is fixedly connected between the upper steaming tube 51 and the lower steaming tube 52. A support block 54 is fixedly connected between the upper steaming tube 51, the lower steaming tube 52 and the inner wall of the shaping box 1. The support block 54 is used to support the upper steaming tube 51 and the lower steaming tube 52 in the position inside the shaping box 1. The lower steaming tube 52 is connected to an external steam generator through its end, so that steam is continuously delivered to the upper steaming tube 51 and the lower steaming tube 52 through the lower steaming tube 52.
[0032] Working Principle: In use, the heating roller 13 is preheated by electricity. Then, the end of the lower steam pipe 52 is connected to an external high-temperature steam generator. Steam generated inside the steam generator is output through the lower steam pipe 52. The fiber filaments are mounted on the outer ring of the winding rod 2, shaping the conveying path of the chemical fiber filaments. The chemical fiber filaments pass through the bristles of the brush block 3, removing broken filaments, stray filaments, and impurities, ensuring the filaments entering the shaping box 1 are clean and free of impurities. The chemical fiber filaments are then split into strands and passed through the outer ring of the rotating wheel 46, subsequently entering the interior of the shaping box 1. They are evenly spread on the surface of the heating roller 13, passing over the surface of the heating roller 13 and being pulled out from the discharge port 12, thus completing the conveying path shaping. When the chemical fiber filaments pass through the heating roller 13 near the inlet 11, they are initially preheated. Then, they pass through the upper steam pipe 51, where steam is evenly sprayed onto the upper surface of the chemical fiber filaments through the vent holes, and then pass through the middle heating roller 13. Afterwards, the lower steam pipe 52 sprays steam through the vent to heat the lower surface of the chemical fiber filament. Through the cooperation between the heating roller 13 and the steam device 5, the upper and lower surfaces of the chemical fiber filament are heated evenly, so that the chemical fiber filament can be shaped as soon as possible. Due to the position of the heating roller 13, the residence time of the chemical fiber filament inside the shaping box 1 can be extended. After the chemical fiber filament is heated, it will generate a thermal expansion effect, which will change the original tension of the chemical fiber filament. After the tension is changed, the coil spring 43 drives the rotating rod 42 to rotate inside the fixed cylinder 41 through the coiling force, thereby adjusting the tension of the chemical fiber filament. When the tension is too tight, the rotating rod 42 inside the fixed cylinder 41 rotates in the vertical direction to tighten the chemical fiber filament. When the tension is too loose, the chemical fiber pushes against the rotating wheel 46, and the rotating rod 42 is forced to rotate inside the fixed cylinder 41 to adjust the tension of the chemical fiber filament to a relatively loose state, which achieves the effect of adaptive elastic adjustment of tension.
