Description

Technical Field

[0001] This application relates to fiber twisting equipment, and in particular to a protective structure for a twisting machine. Background Technology

[0002] In the structural design of fiber twisting equipment, to ensure fiber stability during transmission and prevent fiber misalignment from affecting twisting accuracy, a metal protective ring is typically installed at the front end of the twisting device, forming a specific gap between it and the equipment housing for fiber passage. The size of this gap must strictly match the fiber's thickness to ensure smooth fiber transmission while also providing guidance and restraint. However, in actual production operation, as the fiber continuously passes through the gap between the protective ring and the housing at a certain speed, it inevitably experiences continuous and frequent friction with the inner wall of the metal protective ring.

[0003] This friction directly leads to two core problems: First, the generation of static electricity. Due to the significant difference in dielectric constant between fibers and metals, charge transfer and accumulation occur during friction, resulting in a large amount of static electricity on the fiber surface. This static electricity not only causes mutual repulsion or attraction between fibers, leading to fiber bundle dispersion and increased fuzz, but in severe cases, it can also affect the feeding stability of fibers in the twisting device, resulting in uneven yarn twist and reduced yarn mechanical properties and appearance quality. Second, fiber wear. Although the metal protective ring undergoes certain surface treatments, its surface will still cause some scratching and abrasion to the fibers during long-term frictional contact. Especially for some fiber materials with lower strength and more fragile surface structures, this wear will directly damage the internal structure of the fiber, leading to fiber breakage and shortening. This not only increases the waste rate in the production process but also reduces the strength and evenness of the final yarn, seriously affecting the quality and market competitiveness of textile products. Utility Model Content

[0004] In order to overcome the shortcomings of existing metal protective rings that are prone to generating static electricity and abrading fibers, this application provides a protective structure for a twisting machine that can reduce abrasion and static electricity generation in the protective fibers before they enter the traction device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a protective structure for a twisting machine, comprising a base, a turntable rotatably connected to the base, a through hole on the turntable, a housing for placing fiber raw materials mounted on the turntable, the fiber raw materials being fixed relative to the base, a roller on the upper side of the housing, and a traction device for pulling the fiber raw materials out of the housing, a protective structure sleeved on the outer side of the housing, the side of the protective structure facing the housing being made of insulating material, one end of the fiber raw materials first passing through the through hole of the turntable, then exiting from the bottom of the housing, then passing through the gap between the outer side of the housing and the protective structure, then passing around the roller and connecting to the traction device.

[0006] After adopting the above technical solution, this application has the following advantages: Metal protective rings, due to the large difference in dielectric constant between themselves and fibers, are prone to charge transfer and accumulation during friction, leading to fiber bundle dispersion, increased fuzz, and uneven yarn twist. This application designs the protective structure facing the shell as an insulating material, fundamentally cutting off the path of a large amount of charge transfer between the fiber and the protective structure, significantly reducing the generation and accumulation of static electricity. This design effectively avoids interference from static electricity on fiber transmission, ensuring that the fiber maintains a stable bundle shape when passing through the gap between the shell and the protective structure, reducing fuzz generation, and thus ensuring the feeding stability of the fiber entering the traction device and subsequent twisting stage. Simultaneously, it reduces wear between fuzzy fibers and the protective ring or shell. Traditional metal protective rings cause fibers to bulge due to static electricity, easily snagging with the protective ring or shell, resulting in severe wear. This application uses an insulating material to reduce fiber wear, thereby reducing the probability of uneven yarn twist, significantly improving the mechanical properties and appearance quality of the yarn, and also avoiding secondary damage to fiber quality caused by static electricity attracting dust and impurities.

[0007] Preferably, the protective structure is made of a smooth and insulating material on the side facing the housing, further reducing fiber wear.

[0008] Furthermore, the protective structure includes a bracket for fixing the protective structure and a protective ring facing one side of the housing, the protective ring being mounted on the bracket.

[0009] By adopting the aforementioned technical solution, the protective structure is divided into a support bracket for fixation and a protective ring facing the shell. The core advantage lies in the fact that the support bracket achieves a stable connection between the protective structure and the equipment. Compared to the integrated protective structure, which relies too heavily on the strength of the shell itself for fixation, the independent support bracket can be designed with suitable fixing points according to the equipment installation requirements (such as connecting with load-bearing components such as the twisting machine frame and base), significantly improving the installation stability of the protective structure. During long-term operation of the equipment, even if fiber transmission generates a certain impact force or the equipment experiences slight vibration, the support bracket can ensure that the protective ring always maintains a stable relative position with the shell, avoiding changes in the gap size between the protective ring and the shell due to ring misalignment. This improvement effectively avoids the problems of excessively large gaps losing their limiting and guiding function, and excessively small gaps exacerbating fiber friction, ensuring the long-term stability of the protective ring's electrostatic suppression and wear protection effect on the fibers, further improving the consistency of fiber transmission and yarn quality.

[0010] Furthermore, the protective ring is made of one of the following materials: polytetrafluoroethylene, perfluoroethylene propylene, polychlorotrifluoroethylene, polyetheretherketone, polyimide, and polyethylene.

[0011] Using the aforementioned technical solution, the protective rings are made of fluorinated polymers such as polytetrafluoroethylene (PTFE), perfluoroethylene propylene (PFEP), and polychlorotrifluoroethylene (PTFE), as well as polyetheretherketone (PEEK), polyimide, and polyethylene. These are all typical low-dielectric-constant insulating materials, with dielectric constants generally lower than those of traditional metals (metal dielectric constants approach infinity), and extremely high surface resistance (typically exceeding 10¹²Ω). These material characteristics significantly reduce charge transfer efficiency when fibers rub against the protective ring. On one hand, the low dielectric constant reduces the intensity of charge separation during friction; on the other hand, the high surface resistance effectively prevents charge flow and accumulation on the protective ring surface, avoiding the protective ring becoming a "charge transfer station" and exacerbating fiber charging. Compared to ordinary insulating materials, these polymers exhibit slower electrostatic decay (carrying only a small amount of charge themselves and not easily transferring it to the fibers), minimizing electrostatic residue on the fiber surface. This completely solves the electrostatic problems caused by large differences in dielectric constants in traditional metal protective rings, further preventing fiber bundle dispersion, increased fuzz, and unstable feeding, providing more reliable electrostatic protection for yarn quality.

[0012] Furthermore, the protective structure is a ring fitted onto the outside of the shell.

[0013] Using the aforementioned technical solution, the core adaptability dimension of the ring-shaped protective structure is concentrated on its inner diameter. For twisting machine housings of different diameters, only the inner diameter of the ring needs to be adjusted to achieve adaptation, without requiring a redesign of the overall structural form. From a manufacturing perspective, the ring structure is a symmetrical annular component with a simple molding process (such as injection molding and cutting), requiring no complex three-dimensional molds or multiple processing steps. The amount of raw materials used is also far less than that of a barrel-shaped structure, significantly reducing the manufacturing cost of the protective structure.

[0014] Furthermore, the protective structure consists of multiple rings spaced vertically apart.

[0015] By employing the aforementioned technical solution, compared to a single ring that can only protect a specific section of the fiber transmission path, multiple rings spaced vertically can form multiple "protective barriers" along the transmission direction of the fiber from the bottom of the shell to the roller, achieving segmented protection throughout the entire path. During transmission, each time the fiber passes through a ring, it is limited and insulated by that ring, increasing the protection range along the fiber transmission path.

[0016] Furthermore, the outer diameter of the ring is adapted to the outer diameter of the shell.

[0017] Furthermore, the protective structure is a protective barrel fitted onto the outside of the shell.

[0018] By adopting the aforementioned technical solution, the barrel-shaped protective structure, compared with the ring-shaped protective structure, expands the protection range from a single plane to a complete "cylindrical space," which can achieve more comprehensive protection. This ensures that the fiber can be wrapped and protected by the inner wall of the barrel-shaped structure no matter which direction it deviates in the entire three-dimensional transmission path, and isolates impurities such as fiber dust and lint that may exist in the workshop, thereby reducing the possibility of fiber contamination during transmission.

[0019] Furthermore, the bracket is a metal bracket.

[0020] Using the aforementioned technical solution, the metal support, thanks to the superior mechanical properties of metal materials (such as steel and aluminum alloys), can provide the protective ring with support strength and rigidity far exceeding that of non-metallic supports such as plastics. During the long-term operation of the twisting machine, the protective ring needs to withstand the continuous frictional force during fiber transmission, the impact force generated by equipment vibration, and the load brought by its own weight. The metal support can effectively resist these external forces, preventing the protective ring from shifting or falling off due to deformation or breakage of the support.

[0021] Furthermore, the metal bracket is connected to the base and grounded.

[0022] Using the aforementioned technical solution, the metal bracket itself possesses excellent conductivity. When connected to the base and grounded, it forms a complete electrostatic discharge path of "protective ring - metal bracket - base - ground." Although the protective ring, made of insulating material, significantly reduces static electricity generation, a small amount of residual static electricity may still accumulate on the fiber surface during long-term high-speed friction. Some of this static electricity may be transferred to the metal bracket through air induction or slight contact. Through the grounding design, this transferred static electricity can be conducted to the ground in real time, preventing static electricity from accumulating on the bracket surface and subsequently affecting the fibers or adsorbing dust and impurities from the air.

[0023] Furthermore, a magnetic suction assembly extending to the side of the housing is fixedly connected to the base. The magnetic suction assembly is magnetic on the side facing the housing, and is used to attract and restrict the rotation of the housing.

[0024] Using the aforementioned technical solution, the magnetic assemblies secure the housing through magnetic attraction, a non-rigid contact fixing method. Compared to traditional rigid fixing methods such as side bolts or clamps, this completely avoids direct frictional contact between the fixing components and the housing sides. During long-term use, even with slight vibrations, the housing sides will not show scratches or wear due to friction between the fixing structure and the housing. This is especially beneficial for housings with high surface precision requirements, effectively protecting their appearance and structural integrity and extending their service life. Simultaneously, non-contact fixing avoids the deformation of the housing sides that can occur with rigid fixing, ensuring that the gap between the housing and the protective structure always meets design standards and guarantees stable protective performance.

[0029] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0030] like Figures 1 to 5As shown, the twisting machine in this application specifically includes: a base 1 placed on the ground, a fixing column 51 for fixing fiber raw material 5 on the base 1, a cylindrical shell 4 fitted around the fiber raw material 5 mounted on the fixing column 51, the shell 4 having an opening at the top and a turntable 2 with a through hole 3 at the bottom, the turntable 2 and the shell 4 being able to rotate relative to each other, a protective ring 81 fitted around the outside of the shell 4 to restrict the fiber raw material 5 within the range of the protective ring 81 during transmission and prevent it from expanding outward, and a detection device above the opening on the shell 4. The optical probe 9 for detecting whether the fiber material 5 is exhausted has two specific designs. One is to set the optical probe 9 at the fixed plate 92 with a hole 91 on the upper side of the housing 4. The detection part of the optical probe 9 is located at the hole 91, so that the fiber bypasses the hole 91 set by the probe. When the fiber is exhausted, the optical probe 9 detects that there is no fiber at the hole 91, that is, it is determined that the fiber material 5 is exhausted. The second design is to directly target the fiber material 5 inside the housing 4 for detection. After the fiber material 5 is exhausted, the diameter decreases to a set value, that is, it is determined that the fiber material 5 is exhausted. The upper side of the housing 4 is also provided with rollers 6. Preferably, there are multiple rollers 6 for multiple winding of fibers to ensure that the fibers maintain tension and sufficient twisting stroke before entering the traction device 7. Between the rollers 6 and the traction device 7, there is a winding structure 71 for guiding the fibers to be evenly distributed. The winding structure includes a winding motor 72, an actuator driven by the winding motor 72, and a guide 74 installed on the actuator. One end of the guide 74 is fixed to the actuator and can move linearly back and forth with the actuator. The other end is a guide end, specifically a semi-circular ring shape that is concave inward, so that the fibers can be guided by the guide end of the guide 74 and thus be evenly fed into the traction device 7. The traction device 7 also includes a winding motor 75 and a winding drum 76 driven by the winding motor 75. A twisting spindle 77 is also provided between the winding drum 76 and the guide 74. The twisting spindle 77 and the winding drum 76 have a certain preload. The twisting method of the twisting machine is as follows: when one end of the fiber raw material 5 is transmitted out of the housing 4, the rotation of the turntable 2 realizes the staggered rotation of the two ends of the fiber raw material 5, realizing the first coarse twisting. This ensures that the fiber raw material 5 remains bundled during the transmission to the take-up drum, reducing the possibility of static electricity generation and enhancing the strength of the fiber. The protective ring 81 can restrict the rotating fiber within a certain range, ensuring the stability and reliability of the fiber during coarse twisting. The multiple rollers above the housing can ensure that the rotating fiber has sufficient coarse twisting stroke. Under the action of the traction device 7, the twisting spindle 77 and the guide 74, the fiber is twisted a second time to achieve fine twisting. This ensures that the fiber has sufficient twist during the two twisting processes, enhancing the strength and toughness of the fiber.

[0031] This application provides a protective structure 8 for a twisting machine, including a base 1, a turntable 2 rotatably connected to the base 1, a through hole 3 on the turntable 2, a housing 4 for placing fiber raw material 5 mounted on the turntable 2, the fiber raw material 5 being fixed relative to the base 1, a roller 6 on the upper side of the housing 4, and a traction device 7 for pulling the fiber raw material 5 out of the housing 4, a protective structure 8 sleeved on the outer side of the housing 4, the side of the protective structure 8 facing the housing 4 being made of insulating material, one end of the fiber raw material 5 first passing through the through hole 3 of the turntable 2, then exiting from the bottom of the housing 4, then passing through the gap between the outer side of the housing 4 and the protective structure 8, then passing around the roller 6 and connecting to the traction device 7.

[0032] By adopting the above technical solution, this application has the following advantages: Due to the large difference in dielectric constant between the metal protective ring 81 and the fiber, it is easy to cause charge transfer and accumulation during friction, which in turn leads to fiber bundle dispersion, increased fuzz, and uneven yarn twist. However, this application designs the side of the protective structure 8 facing the shell 4 to be made of insulating material, which fundamentally cuts off the path of a large amount of charge transfer between the fiber and the protective structure 8, and greatly reduces the generation and accumulation of static electricity. This design effectively avoids interference from static electricity on fiber transmission, ensuring that the fiber maintains a stable bundle shape when passing through the gap between the shell 4 and the protective structure 8, reducing fuzz formation, and thus ensuring the feeding stability of the fiber entering the traction device 7 and subsequent twisting stage. At the same time, it reduces wear between the fuzzy fiber and the protective ring 81 or the shell 4. Traditional metal protective rings 81 can cause the fiber to bulge due to static electricity, making it easy for the fiber to snag on the protective ring 81 or the shell 4, resulting in severe wear. This application uses insulating materials to reduce fiber wear, thereby reducing the probability of uneven yarn twist, significantly improving the mechanical properties and appearance quality of the yarn, and also avoiding secondary damage to fiber quality caused by static electricity attracting dust and impurities.

[0033] Preferably, the side of the protective structure 8 facing the housing 4 is made of a smooth and insulating material, further reducing the degree of fiber wear.

[0034] Furthermore, the protective structure 8 includes a bracket 82 for fixing the protective structure 8 and a protective ring 81 facing the housing 4, the protective ring 81 being mounted on the bracket 82.

[0035] By adopting the aforementioned technical solution, the protective structure 8 is divided into a bracket 82 for fixation and a protective ring 81 facing the housing 4. The core advantage lies in the fact that the bracket 82 achieves a stable connection between the protective structure 8 and the equipment. Compared to the integral protective structure 8, which relies too heavily on the strength of the housing 4 itself for fixation, the independent bracket 82 can be designed with suitable fixing points according to the equipment installation requirements (such as connecting with load-bearing components such as the twisting machine frame and base 1), significantly improving the installation stability of the protective structure 8. During long-term operation of the equipment, even if the fiber transmission generates a certain impact force or the equipment experiences slight vibration, the bracket 82 can ensure that the protective ring 81 always maintains a stable relative position with the housing 4, avoiding changes in the gap size between the protective ring 81 and the housing 4 due to the offset of the protective ring 81. This improvement can effectively avoid the problems of losing the limiting and guiding function due to excessively large gaps and aggravating fiber friction due to excessively small gaps, ensuring the long-term stability of the electrostatic suppression and wear protection effect of the protective ring 81 on the fibers, and further improving the consistency of fiber transmission and yarn quality.

[0036] Furthermore, the material used for the protective ring 81 is one of polytetrafluoroethylene, perfluoroethylene propylene, polychlorotrifluoroethylene, polyetheretherketone, polyimide, and polyethylene.

[0037] Using the aforementioned technical solution, the protective ring 81 is made of fluorinated polymer materials such as polytetrafluoroethylene, perfluoroethylene propylene, and polychlorotrifluoroethylene, as well as polyetheretherketone, polyimide, and polyethylene. These are all typical low-dielectric-constant insulating materials, with dielectric constants generally lower than those of traditional metals (metal dielectric constants approach infinity), and extremely high surface resistance (typically exceeding 10¹²Ω). These material characteristics significantly reduce charge transfer efficiency when the fiber contacts and rubs against the protective ring 81. On the one hand, the low dielectric constant reduces the intensity of charge separation during friction; on the other hand, the high surface resistance effectively prevents charge from flowing and accumulating on the surface of the protective ring 81, avoiding the protective ring 81 becoming a "charge transfer station" and exacerbating fiber charging. Compared to ordinary insulating materials, these polymer materials have a slower electrostatic decay rate (they only carry a small amount of charge themselves and it is not easy to transfer to the fibers), which can minimize the electrostatic residue on the fiber surface and completely solve the electrostatic problem caused by the large difference in dielectric constant of traditional metal protective rings 81. This further avoids phenomena such as fiber bundle dispersion, increased hairiness, and unstable feeding, providing a more reliable electrostatic protection guarantee for yarn quality.

[0038] Furthermore, the protective structure 8 is a ring fitted onto the outside of the housing 4.

[0039] Using the aforementioned technical solution, the core adaptability dimension of the circular protective structure 8 is concentrated on its inner diameter. For twisting machine housings 4 with different diameters, only the inner diameter of the ring needs to be adjusted to achieve adaptation, without the need to redesign the overall structure. From a manufacturing perspective, the circular structure is a symmetrical ring component with a simple molding process (such as injection molding, cutting, etc.), requiring no complex three-dimensional molds or multiple processing steps. The amount of raw materials used is also far less than that of the barrel structure, which can significantly reduce the manufacturing cost of the protective structure 8.

[0040] Furthermore, the protective structure 8 consists of multiple rings spaced vertically apart.

[0041] By adopting the aforementioned technical solution, compared to a single ring that can only protect a specific section in the fiber transmission path, multiple rings spaced vertically can form multiple "protective barriers" along the transmission direction of the fiber from the bottom of the housing 4 to the roller 6, achieving segmented protection throughout the entire path. During transmission, each time the fiber passes through a ring, it is limited and insulated by that ring, increasing the protection range along the fiber transmission path.

[0042] Furthermore, the outer diameter of the ring is adapted to the outer diameter of the housing 4.

[0043] Furthermore, the protective structure 8 is a protective barrel 83 fitted onto the outside of the shell 4.

[0044] By adopting the aforementioned technical solution, the barrel-shaped protective barrel 83 structure, compared with the ring-shaped protective structure 8, expands the protection range from a single plane to a complete "cylindrical space", which can achieve more complete protection. This allows the fiber to be wrapped and protected by the inner wall of the barrel-shaped structure in any direction it deviates in the entire three-dimensional transmission path, and isolates impurities such as fiber dust and lint that may exist in the workshop, thereby reducing the possibility of fiber contamination during transmission.

[0045] Furthermore, the bracket 82 is a metal bracket 82.

[0046] By employing the aforementioned technical solution, the metal support 82, thanks to the superior mechanical properties of metal materials (such as steel and aluminum alloys), can provide the protective ring 81 with support strength and rigidity far exceeding that of non-metallic supports 82 such as plastics. During the long-term operation of the twisting machine, the protective ring 81 needs to withstand the continuous frictional force during fiber transmission, the impact force generated by equipment vibration, and the load brought by its own weight. The metal support 82 can effectively resist these external forces, preventing the protective ring 81 from shifting or falling off due to deformation or breakage of the support 82.

[0047] Furthermore, the metal bracket 82 is connected to the base 1 and grounded.

[0048] Using the aforementioned technical solution, the metal bracket 82 itself possesses good conductivity. When connected to the base 1 and grounded, it forms a complete electrostatic discharge path of "protective ring 81 - metal bracket 82 - base 1 - ground". Although the protective ring 81, made of insulating material, can significantly reduce static electricity generation, a small amount of residual static electricity may still accumulate on the fiber surface during long-term high-speed friction, and some of this static electricity may be transferred to the metal bracket 82 through air induction or slight contact. Through the grounding design, this static electricity transferred to the metal bracket 82 can be conducted to the ground in real time, preventing static electricity from accumulating on the surface of the bracket 82 and subsequently affecting the fibers or adsorbing dust and impurities from the air.

[0049] Furthermore, a magnetic suction assembly 11 extending to the side of the housing 4 is fixedly connected to the base 1. The magnetic suction assembly 11 is magnetic on the side facing the housing 4, and is used to attract and restrict the rotation of the housing 4.

[0050] Using the aforementioned technical solution, the magnetic attraction component 11 fixes the housing 4 through magnetic attraction, which is a non-rigid contact fixing method. Compared with traditional rigid fixing methods such as side bolt tightening and clamping, it can completely avoid direct frictional contact between the fixing component and the side of the housing 4. During long-term use, even if the equipment experiences slight vibration, the friction between the fixing structure and the housing 4 will not cause scratches or wear on the side of the housing 4. Especially for housings with high surface precision requirements, it can effectively protect their appearance and structural integrity, and extend the service life of the housing 4. At the same time, non-contact fixing also avoids the deformation of the side of the housing 4 that may be caused by rigid fixing, ensuring that the gap between the housing 4 and the protective structure 8 always meets the design standards and guarantees stable protective effect.

[0051] In addition to the preferred embodiments described above, this application has other implementation methods. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection claimed in this application.
