Description

Technical Field

[0001] This application relates to the field of spinning machine technology, and in particular to a high-strength spinning machine head grounding wire. Background Technology

[0002] In the textile production industry, the spinning frame is a key piece of equipment for twisting fibers and forming fine yarn. The grounding device at the head of the frame is crucial to the stability of equipment operation and product quality. As the core component for releasing static electricity at the head of the spinning frame, the grounding wire must continuously discharge the static electricity generated during equipment operation to prevent static electricity from attracting fly shavings (i.e., "scratching") and interfering with the normal spinning process, while also ensuring the safety of the equipment's circuitry.

[0003] Currently, the grounding wires of spinning machine heads mostly adopt a mesh structure design. However, this type of mesh grounding wire has obvious defects in actual use: First, the mesh structure is prone to tangling and accumulating fly shavings (fiber impurities). When employees clean the machine daily with a twisting gun, the rotating parts of the twisting gun are easily tangled with the mesh wire, causing the grounding wire to break and shorten its service life. Second, after the grounding wire breaks, static electricity cannot be released through the normal path. The accumulation of static electricity on the equipment surface will aggravate the adsorption of fly shavings (i.e., the "fly shavings sticking" phenomenon), which not only affects the quality of spinning but also requires frequent machine shutdowns for cleaning, reducing production efficiency. Third, the connection between the mesh grounding wire and the machine head is mostly a simple winding method, which is prone to loosening due to long-term equipment vibration, further weakening the static electricity release effect. Moreover, after breakage or loosening, frequent replacement and repair are required, increasing maintenance costs and downtime.

[0004] Therefore, in response to the problems of easy breakage of the grounding wire of the existing spinning machine head, poor static discharge, and cumbersome maintenance, there is an urgent need for a grounding wire modification scheme with a more reasonable structure and stronger stability to improve the reliability of equipment operation and production efficiency. Utility Model Content

[0005] The purpose of this application is to provide a high-strength grounding wire for the head of a spinning machine, which has advantages such as easy disassembly and solves the problems mentioned in the background art.

[0006] This application provides a high-strength grounding wire for a spinning machine head, employing the following technical solution: A high-strength grounding wire for a spinning machine head includes a spinning machine head frame, a ring unit, and a grounding wire assembly. The grounding wire assembly includes a two-color multi-strand copper core flexible wire and a smooth sheath fixedly connected to the outer surface of the two-color multi-strand copper core flexible wire. Both ends of the two-color multi-strand copper core flexible wire are fitted with perforated galvanized steel plates. A grounding bolt is installed at one end of the spinning machine head frame, and the grounding bolt is fitted into a through hole inside the corresponding perforated galvanized steel plate. A positioning bolt is installed at one end of the ring unit, and the positioning bolt is fitted into a through hole inside the corresponding perforated galvanized steel plate.

[0007] By adopting the above technical solution, the original mesh grounding wire is replaced with a two-color multi-strand copper core flexible wire, and a smooth wire sheath is used to reduce the accumulation of fly shavings and prevent them from being broken by the twisting gun during cleaning. A perforated galvanized steel plate is used as a connecting medium and is fixed to the spinning machine head frame and the ring unit by grounding bolts and positioning bolts, which not only enhances the installation stability of the grounding wire assembly, but also strengthens the static discharge through metal conduction, solving the problems of poor static discharge and easy sticking of fly shavings on the machine in the original structure.

[0008] Preferably, a stop washer and a flat washer are provided between the perforated galvanized steel sheet and the head frame of the spinning machine. The stop washer is located below the flat washer and is in contact with the upper surface of the head frame of the spinning machine.

[0009] By adopting the above technical solution, the stop shim can prevent relative sliding between the perforated galvanized steel plate and the head frame of the spinning machine due to machine vibration. The flat shim can disperse the pressure of the perforated galvanized steel plate on the surface of the head frame of the spinning machine, avoid local wear, and at the same time maintain close contact between the two to ensure a stable electrostatic conduction path.

[0010] Preferably, a first elastic washer is provided between the grounding bolt and the perforated galvanized steel plate, the first elastic washer being sleeved on the grounding bolt and in contact with the surface of the perforated galvanized steel plate.

[0011] By adopting the above technical solution, the first elastic gasket uses its own elasticity to compensate for the gap between the grounding bolt and the perforated galvanized steel plate. When the machine vibrates, it can buffer the impact force and prevent the grounding bolt from loosening. At the same time, it maintains close contact between the perforated galvanized steel plate and the grounding bolt, ensuring that static electricity can be smoothly conducted to the spinning machine head frame through the grounding bolt.

[0012] Preferably, a spacer is provided between the perforated galvanized steel sheet and the steel ring unit. The spacer is fitted onto the positioning bolt and is respectively attached to the steel ring unit and the perforated galvanized steel sheet.

[0013] By adopting the above technical solution, the pad can adjust the distance between the perforated galvanized steel plate and the steel ring unit, avoiding mutual wear caused by direct contact between the two, while providing stable support for the perforated galvanized steel plate, ensuring that the grounding wire assembly is installed accurately on one side of the steel ring unit, and reducing the grounding wire pulling problem caused by position deviation.

[0014] Preferably, a second elastic washer is provided between the perforated galvanized steel sheet and the positioning bolt, the second elastic washer being sleeved on the positioning bolt and fitting against the surface of the perforated galvanized steel sheet.

[0015] By adopting the above technical solution, the second elastic gasket offsets the assembly gap between the positioning bolt and the perforated galvanized steel plate through elastic deformation. It can prevent the positioning bolt from loosening when the machine vibrates during operation, ensure the reliable connection between the perforated galvanized steel plate and the positioning bolt, and ensure the continuous effectiveness of the electrostatic conduction path on the steel ring unit side.

[0016] Preferably, the end of the two-color multi-strand copper core flexible wire is fixedly connected to the perforated galvanized steel plate by crimping or welding, and the copper core of the two-color multi-strand copper core flexible wire is in conductive contact with the metal part of the perforated galvanized steel plate.

[0017] By adopting the above technical solutions, the crimping or welding connection method can ensure that the two-color multi-strand copper core flexible wire is firmly fixed to the perforated galvanized steel plate, avoiding the wire from falling off due to vibration; and the direct conductive contact between the copper core and the metal part of the perforated galvanized steel plate can reduce the contact resistance, so that static electricity can be efficiently conducted from the two-color multi-strand copper core flexible wire to the perforated galvanized steel plate, solving the problems of easy loosening and poor conductivity of the original winding connection method.

[0018] Preferably, the bottom end of the grounding bolt is threaded with a grounding nut.

[0019] By adopting the above technical solution, the grounding nut can lock the grounding bolt from below, and cooperate with the spinning machine head frame to clamp and fix the perforated galvanized steel plate, preventing the grounding bolt from loosening during long-term machine vibration, ensuring the connection stability between the perforated galvanized steel plate and the spinning machine head frame, and maintaining the continuous reliability of the grounding circuit.

[0020] Preferably, the top of the grounding bolt has a hexagonal groove.

[0021] By adopting the above technical solution, the hexagonal slot can be adapted to special tools for the installation and removal of grounding bolts. Especially in the narrow space of the spinning machine head, it can simplify the installation and maintenance operations, reduce the installation problems or disassembly difficulties caused by tool compatibility issues, and improve the maintenance efficiency of the grounding wire assembly.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This high-strength grounding wire for a spinning machine head replaces the original mesh grounding wire with a two-color multi-strand copper core flexible wire. A smooth wire sheath reduces fly ash accumulation and solves the problem of the grounding wire being easily broken by the twisting gun during cleaning. A perforated galvanized steel plate serves as the connecting medium, and is fixed to the spinning machine head frame and ring unit via grounding bolts and positioning bolts. Compared to the original winding connection method, this enhances the installation stability of the grounding wire assembly. Stopping washers and flat washers prevent the perforated galvanized steel plate from sliding or wearing against the spinning machine head frame due to vibration. A first elastic washer and a second elastic washer utilize spring... The neutralizing gap prevents the grounding bolt positioning bolt from loosening, ensuring a stable electrostatic conduction path. The two-color multi-strand copper core flexible wire is fixed to the perforated galvanized steel plate by crimping or welding, solving the problems of easy loosening and poor conductivity of the original winding connection. The grounding nut locks the grounding bolt from below to ensure long-term reliable connection. The hexagonal groove simplifies the installation and removal of the grounding bolt to improve maintenance efficiency. Through overall structural optimization, the grounding wire's breakage resistance and electrostatic discharge efficiency are effectively improved, reducing machine scratches. At the same time, the connection stability and maintenance convenience are enhanced, comprehensively improving the shortcomings of the existing technology. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A high-strength grounding wire for the head of a fine spinning machine, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The system includes a spinning machine head frame 1, a ring rail unit 2, and a grounding wire assembly 3. The grounding wire assembly 3 includes a two-color multi-strand copper core flexible wire 301 and a smooth wire sheath 302 fixedly connected to the outer surface of the two-color multi-strand copper core flexible wire 301. Both ends of the two-color multi-strand copper core flexible wire 301 are equipped with perforated galvanized steel plates 303. The ends of the two-color multi-strand copper core flexible wire 301 are fixedly connected to the perforated galvanized steel plates 303 by crimping or welding. The copper core of the two-color multi-strand copper core flexible wire 301 is in conductive contact with the metal part of the perforated galvanized steel plate 303. The crimping or welding connection method ensures that the two-color multi-strand copper core flexible wire 301 and the perforated galvanized steel plate 303 are in conductive contact. The steel plate 303 is firmly fixed to prevent the wire from falling off due to vibration. The direct conductive contact between the copper core and the metal part of the perforated galvanized steel plate 303 reduces the contact resistance and allows static electricity to be efficiently conducted from the two-color multi-strand copper core flexible wire 301 to the perforated galvanized steel plate 303. This solves the problems of easy loosening and poor conductivity of the original winding connection method. One end of the spinning machine head frame 1 is equipped with a grounding bolt 307, which is fitted into the through hole inside the corresponding perforated galvanized steel plate 303. One end of the ring unit 2 is equipped with a positioning bolt 312, which is fitted into the through hole inside the corresponding perforated galvanized steel plate 303.

[0033] Reference Figure 1 , Figure 2 and Figure 4 A stop washer 304 and a flat washer 305 are provided between the perforated galvanized steel plate 303 and the spinning machine head frame 1. The stop washer 304 is located below the flat washer 305 and contacts the upper surface of the spinning machine head frame 1. The stop washer 304 can prevent relative sliding between the perforated galvanized steel plate 303 and the spinning machine head frame 1 due to machine vibration. The flat washer 305 can disperse the pressure of the perforated galvanized steel plate 303 on the surface of the spinning machine head frame 1, avoid local wear, and maintain close contact between the two to ensure a stable electrostatic conduction path. Grounding bolt 30 A first elastic washer 306 is provided between the grounding bolt 307 and the perforated galvanized steel plate 303. The first elastic washer 306 is sleeved on the grounding bolt 307 and is in contact with the surface of the perforated galvanized steel plate 303. The first elastic washer 306 uses its own elasticity to compensate for the gap between the grounding bolt 307 and the perforated galvanized steel plate 303. When the machine vibrates, it can buffer the impact force and prevent the grounding bolt 307 from loosening. At the same time, it maintains a tight contact between the perforated galvanized steel plate 303 and the grounding bolt 307, ensuring that static electricity can be smoothly conducted to the spinning machine head frame 1 through the grounding bolt 307.

[0034] Example 2: A high-strength grounding wire for the head of a fine spinning machine, referring to... Figure 1 , Figure 3 and Figure 4 Based on the same concept as Embodiment 1 above, this embodiment proposes that the bottom end of the grounding bolt 307 is threaded with a grounding nut 308. The grounding nut 308 can lock the grounding bolt 307 from below, and cooperate with the spinning machine head frame 1 to clamp and fix the perforated galvanized steel plate 303, preventing the grounding bolt 307 from loosening during long-term machine vibration, ensuring the connection stability between the perforated galvanized steel plate 303 and the spinning machine head frame 1, and maintaining the continuous reliability of the grounding circuit. The top end of the grounding bolt 307 has a hexagonal groove 309, which can be adapted to special tools for loading and unloading the grounding bolt 307. Especially in the narrow space of the spinning machine head, it can simplify the installation and maintenance operation, reduce the installation failure or disassembly difficulty caused by tool compatibility issues, and improve the maintenance efficiency of the grounding wire assembly 3.

[0035] Reference Figure 1 , Figure 3 and Figure 4 A spacer 310 is provided between the perforated galvanized steel plate 303 and the steel ring unit 2. The spacer 310 is fitted onto the positioning bolt 312 and is respectively attached to the steel ring unit 2 and the perforated galvanized steel plate 303. The spacer 310 can adjust the distance between the perforated galvanized steel plate 303 and the steel ring unit 2 to avoid mutual wear caused by direct contact between the two. At the same time, it provides stable support for the perforated galvanized steel plate 303, ensuring the accurate installation position of the grounding wire assembly 3 on one side of the steel ring unit 2, and reducing the grounding wire pulling problem caused by positional deviation. A second elastic washer 311 is provided between the zinc-coated steel plate 303 and the positioning bolt 312. The second elastic washer 311 is sleeved on the positioning bolt 312 and fits against the surface of the perforated galvanized steel plate 303. The second elastic washer 311 compensates for the assembly gap between the positioning bolt 312 and the perforated galvanized steel plate 303 by means of elastic deformation. It can prevent the positioning bolt 312 from loosening when the machine vibrates during operation, ensure the reliable connection between the perforated galvanized steel plate 303 and the positioning bolt 312, and ensure that the electrostatic conduction path on both sides of the steel ring unit remains effective.

[0036] The implementation principle of this application embodiment is as follows: The spinning machine head frame 1 and the ring unit 2 at the machine head will generate static electricity due to fiber friction and mechanical movement. If this static electricity is not released in time, it will attract surrounding fly waste, forming "sticky fly waste," affecting production quality and efficiency. The modified grounding wire assembly 3 serves as the core path for static electricity conduction. Its two-color multi-strand copper core flexible wire 301, with its excellent conductivity of multi-strand copper core, can quickly collect the static electricity generated by the spinning machine head frame 1 and the ring unit 2. The smooth outer sheath 302, due to its smooth surface, is less prone to fly waste accumulation, avoiding the risk of being broken by the twisting gun during cleaning, and ensuring the continuity of the static electricity conduction path. Static electricity is conducted within the two-color multi-strand copper core flexible wire 301 to the perforated galvanized steel plates 303 at both ends. Since the two-color multi-strand copper core flexible wire 301 and the perforated galvanized steel plate 303 are fixed by crimping or welding, and the copper core is in direct contact with the metal part of the perforated galvanized steel plate 303, the contact resistance is low, and the static electricity can be efficiently transferred to the perforated galvanized steel plate 303. The perforated galvanized steel plate 303 is connected to the spinning machine head frame 1 and the ring unit 2 via grounding bolts 307 and positioning bolts 312, forming a complete conduction circuit. During this process, the stop washer 304 and flat washer 305 prevent relative sliding or surface wear between the perforated galvanized steel plate 303 and the spinning machine head frame 1 due to vibration, ensuring close contact to maintain conductive continuity. The first elastic washer 306 and the second elastic washer 311 compensate for the gap using their own elasticity, preventing the grounding bolts 307 and positioning bolts 312 from loosening due to vibration, ensuring a reliable connection for the perforated galvanized steel plate 303. The pad block 310 adjusts the distance between the perforated galvanized steel plate 303 and the ring unit 2, preventing direct wear and providing stable support. The grounding nut 308 locks the grounding bolt 307 from below, further enhancing the reliability of the long-term connection. The hexagonal slot 309 facilitates the installation and removal of the grounding bolt 307, ensuring rapid restoration of the conduction path during maintenance. Through the synergistic effect of the above components, static electricity can be stably and efficiently discharged from its source, effectively solving problems such as easy breakage of the original mesh grounding wire, poor static discharge, and loose connection, thus ensuring the stable operation of the spinning machine.
