Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to an electrostatic removal device for warping machines. Background Technology

[0002] Warping is the process of winding a certain number of yarns parallel onto a warp beam, and it is an important preparatory step before weaving. During warping, the yarns continuously rub against the yarn guides, tensioners, reeds, and other components at high speeds, easily generating static charge accumulation. The static charge carried on the yarn surface not only causes mutual repulsion or attraction between yarns, resulting in disordered yarn arrangement and increased yarn breaks, but it also attracts dust, lint, and other impurities from the air, affecting the quality of the warp beam winding and the yield rate of subsequent weaving processes. Therefore, equipping warping machines with static electricity removal devices has become an important means in this field to improve production efficiency and product quality.

[0003] Currently, existing methods for removing static electricity in warping machines mainly include passive static eliminators and active static neutralization devices. Passive static eliminators typically use conductive brushes or metal contact rods to conduct static charge away by contacting the yarn. However, they can easily cause mechanical damage to high-speed yarns and have limited effectiveness in eliminating high-potential static electricity. Active static neutralization devices mostly use corona discharge ion bars, which generate positive and negative ions by ionizing air with high voltage. These ions are then transported to the yarn surface by airflow for neutralization. Some devices also incorporate humidification mechanisms to increase the yarn's moisture regain, thereby reducing surface resistance and increasing the static leakage rate.

[0004] However, existing electrostatic removal devices still have many shortcomings in practical applications. First, most devices use open-loop control, which cannot dynamically adjust the neutralization or humidification intensity according to the actual charge on the yarn, resulting in unstable electrostatic removal effects under conditions of large static fluctuations. Second, humidification and neutralization functions are often set independently, lacking coordination, which can easily lead to problems such as over-humidification causing the yarn to become too wet or insufficient neutralization. Third, existing devices lack effective means to detect uneven charge distribution in the circumferential direction of the yarn, and are prone to measurement blind spots due to yarn twisting. In addition, there is a lack of timely and effective collection structures for dust, lint, and other impurities adsorbed by electrostatics, which can easily accumulate inside the equipment or re-adhere to the yarn surface, affecting the cleaning effect and the long-term reliability of the device. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] An electrostatic removal device for a warping machine, such as Figure 1-7 As shown, the device includes a mounting frame 1, a pre-electrostatic monitoring module 2, an auxiliary wire guide frame 3, a liquid phase change adaptive humidification module 4, a compressed air inlet 5, a vortex focusing ion neutralization module 6, and an electrostatic adsorption dust removal module 7.

[0022] Mounting frame 1, serving as the supporting skeleton of the entire device, is made of metal and possesses excellent structural strength and resistance to deformation. The pre-electrostatic monitoring module 2, auxiliary thread guide 3, liquid phase change adaptive humidification module 4, eddy current focusing ion neutralization module 6, and electrostatic adsorption dust removal module 7 are all fixed to mounting frame 1 using bolts or clamps, with mounting frame 1 providing radial fixation for each module. These modules are arranged sequentially along the yarn travel direction. Under the traction of the warping machine, the yarn passes through these modules in sequence. Through this sequential arrangement, the yarn's electrostatic state is first detected, then humidified to increase conductivity, followed by ion neutralization, and finally, the adsorbed impurities are removed, forming a complete closed loop of electrostatic removal and cleaning.

[0023] The pre-electrostatic monitoring module 2 is used to detect the electrostatic charge distribution on the yarn surface and output the corresponding electric field strength signal. It includes an insulating base 8, a non-contact electric field probe 9, a wire frame 10, and an annular shield 11.

[0024] The annular shield 11 is circular in shape and made of metal. Its inner wall has three mounting holes spaced 120° circumferentially, each housing a non-contact electric field probe 9. The annular shield 11 is connected to the warping machine frame via a grounding wire, forming electromagnetic shielding and effectively eliminating the influence of external electromagnetic interference on detection accuracy. The front end (the yarn-facing surface) of the annular shield 11 has a chamfer R3 to prevent the yarn from being scratched by sharp edges when it enters.

[0025] The non-contact electric field probe 9 is used to sense the electric field formed by static charges on the yarn surface. Each probe includes a ceramic substrate and gold-plated interdigitated electrodes deposited on the ceramic substrate, with a spacing of 0.5 mm between the interdigitated electrodes. The gold-plated electrodes have excellent conductivity and oxidation resistance, while the ceramic substrate provides good insulation and high mechanical strength. The probe is mounted using an adjustable bracket to ensure that its distance from the yarn surface is maintained within 10 mm ± 1 mm. The three probes are arranged in a ring, enabling the detection of charge distribution at different locations along the circumference of the yarn, effectively avoiding measurement blind spots caused by yarn twisting.

[0026] During operation, the static charge on the yarn surface creates an electrostatic field in the surrounding space, inducing a potential difference between the interdigitated electrodes of the electric field probe. This weak signal is amplified by a high-impedance operational amplifier (input impedance > 10^15 Ω), outputting a voltage signal of 0-10V corresponding to an electric field strength of 0-50kV / m. The output signals from the three probes are averaged by a conditioning circuit, effectively eliminating measurement errors caused by yarn vibration.

[0027] The insulating base 8 is disposed outside the annular shield 11 and installed between the annular shield 11 and the metal shell of the mounting bracket 1. The insulating base 8 is made of engineering plastic with high insulation performance (such as polytetrafluoroethylene or polyetheretherketone), and its function is to block the electrostatic leakage path and ensure that the electric field measured by the probe comes entirely from the yarn and not from the external structure.

[0028] The lead frame 10 is located at both ends of the insulating base 8 and is made of smooth ceramic rods or polished metal rods. It is used to support and guide the yarn, preventing the yarn from contacting the probe and causing damage to the yarn or contamination to the probe when passing through the annular shield 11. The lead frame 10 works in conjunction with the auxiliary lead guide 3 to maintain the stability of the yarn's position in the detection area.

[0029] The auxiliary yarn guide 3 is fixed to the mounting bracket 1. Its main function is to correct the direction of yarn movement and, in conjunction with the lead frame 10 of the pre-mounted electrostatic monitoring module 2, to support and position the yarn, playing a crucial role in connecting the upper and lower parts of the assembly. Simultaneously, the auxiliary yarn guide 3 facilitates the smooth entry of the yarn into the liquid phase change adaptive humidification module 4, ensuring the uniformity of the humidification process. The auxiliary yarn guide 3 can employ ceramic guide posts or roller structures with smooth surfaces to reduce friction.

[0030] The liquid phase change adaptive humidification module 4 is used to adjust the humidification amount according to the electric field strength signal output by the pre-electrostatic monitoring module 2, so as to increase the surface conductivity of the yarn. It includes a compressed air inlet 5, a yarn passage cavity 12, an opening 13, a gas-liquid mixing cavity 14, a deionized water inlet 15, a micron-level nozzle array 16, a proportional regulating valve 17, and a high-frequency ultrasonic atomizing plate 29.

[0031] The yarn passage cavity 12 is arranged along the yarn axis and has a long cylindrical structure, through which the yarn passes. The top of the yarn passage cavity 12 has an H-shaped structure, which correspondingly forms two independent gas-liquid mixing chambers 14, connected by a pipeline. A compressed air inlet 5 is located at the top of the connecting pipeline for introducing compressed air; a deionized water inlet 15 is connected to one end of the gas-liquid mixing chamber 14 for introducing deionized water.

[0032] The gas-liquid mixing chamber 14 is equipped with a spiral baffle, the surface of which is machined with spiral grooves 1 mm deep. Compressed air enters tangentially from one side of the chamber, while deionized water enters axially. Under the action of the spiral baffle, the two form a high-speed rotating gas-liquid two-phase flow, initially shearing the water into micron-sized droplets. This structural design allows for more thorough gas-liquid mixing, improving subsequent atomization efficiency.

[0033] Two high-frequency ultrasonic atomizing plates 29 are attached to the bottom of the gas-liquid mixing chamber 14 and isolated from the mixing chamber by rubber rings 28. The rubber rings 28 serve a sealing and vibration damping function. The high-frequency ultrasonic atomizing plates 29 are made of piezoelectric ceramic material. When a 1.7MHz high-frequency electrical signal is applied to them, high-frequency mechanical vibration is generated, further atomizing the liquid droplets in the mixing chamber into ultrafine particles of 1μm to 5μm. By adjusting the power of the ultrasonic atomizing plates (within the range of 0-30W), the diameter of the atomized particles can be changed; the higher the power, the finer the particles (down to 1μm), thus preventing the yarn from becoming too wet.

[0034] A micron-sized nozzle array 16 is arranged on the upper and lower sides of the inner wall of the yarn passage cavity 12, with each side arranged in a straight line along the yarn width direction (perpendicular to the yarn travel direction) at a spacing of 15 mm, covering a yarn area with a total width of 60 mm. Each nozzle is embedded with a ruby ​​nozzle core with an orifice diameter of 0.3 mm. Ruby material has extremely high hardness and strong wear resistance, which can maintain the nozzle accuracy over a long period of time. The micron-sized nozzle array 16 is connected to the gas-liquid mixing chamber 14 and is used to uniformly spray the atomized droplets onto the yarn surface.

[0035] The proportional control valve 17 is installed on the inlet pipe of the deionized water inlet 15. It receives a 0-5V signal from the control unit, corresponding to an opening degree of 0-100%, to achieve continuous adjustment of the humidification amount. The control unit dynamically adjusts the opening degree of the proportional control valve 17 according to the electric field strength signal detected by the pre-mounted electrostatic monitoring module 2 and a preset control algorithm (such as PID control), forming a closed-loop control rather than a simple on / off control.

[0036] In addition, several openings 13 are provided on the side wall of the yarn passage cavity 12 to ensure gas flow, prevent atomized water from accumulating in the cavity, and avoid localized excessive moisture in the yarn.

[0037] To improve control accuracy, the liquid phase change adaptive humidification module 4 is also equipped with a temperature and humidity sensor (not shown in the figure) to monitor the ambient humidity in real time. When the ambient humidity exceeds 70%RH, the control unit automatically reduces the humidification rate, forming an inner loop control to prevent excessive humidification from affecting yarn quality.

[0038] The eddy current focusing ion neutralization module 6 is used to generate and deliver positive and negative ions to the yarn surface to neutralize static charge. It includes an annular ion needle disk 18, an insulating cover 19, a Coanda effect airflow plate 20, ion needles 21, and an air passage slit 22.

[0039] The annular ion needle disk 18 is fixed to the mounting bracket 1, and its interior is designed as a cavity to store compressed air. An external air source is connected to the annular ion needle disk 18, and the compressed air enters the cavity and forms a swirling flow within it. The inner ring of the annular ion needle disk 18 is provided with a Coanda effect airflow plate 20, which has an annular structure and a smooth surface to guide the airflow.

[0040] The air passage slit 22 is located on the side of the annular ion needle disk 18 near the Coanda effect airflow plate 20, and is arranged continuously or intermittently along the circumference. Compressed air swirls inside the annular ion needle disk 18 and is then ejected at high pressure from the air passage slit 22, with the ejected airflow outlet facing the outer wall of the Coanda effect airflow plate 20. According to the Coanda Effect, the airflow flows along the outer wall surface of the Coanda effect airflow plate 20, forming a wall-attached jet.

[0041] The inner circumference of the Coanda effect airflow plate 20 is provided with a ring of ion needles 21. The ion needles 21 are made of tungsten needles and have good conductivity and resistance to corona corrosion. Each ion needle 21 is covered with an insulating cover 19, which is made of ceramic or high-voltage resistant engineering plastic. The insulating cover 19 is used to prevent arc discharge between ion needles and to guide the directional diffusion of ions.

[0042] A high-voltage generator (not shown in the figure) outputs ±5kV of high voltage, which is applied to the tip of a tungsten needle to generate corona discharge, ionizing the air into positive and negative ions. A ring-shaped cyclone envelops the generated ions and transports them along the surface of the Coanda effect airflow plate 20, ultimately converging on the yarn surface to efficiently neutralize the static charge carried by the yarn. This structural design makes ion transport more concentrated and directional, improving neutralization efficiency and avoiding ineffective diffusion of ions in an open environment.

[0043] The electrostatic adsorption dust removal module 7 is used to adsorb and collect impurities on the surface of the yarn. It includes a dust collection filter bag 23, a negative pressure fan 24, a negative pressure collection chamber 25, a reverse electrostatic electrode plate 26, and a brush roller ring 27.

[0044] The reverse electrostatic electrode plate 26 comprises a pair of aluminum alloy plates arranged opposite each other on the upper and lower sides of the yarn, respectively. The surface of the plates is coated with an insulating coating, 0.5 mm thick, made of polytetrafluoroethylene or ceramic material, to prevent direct contact between the plates and the yarn, which could cause sparks or electrical breakdown. The upper plate is connected to a +3 kV positive high voltage, and the lower plate is grounded. The distance between the plates and the yarn is 8 mm, forming a uniform high-voltage electrostatic field. When the yarn passes through this electrostatic field, dust, lint, and other impurities carried on its surface are attracted to the direction of the plates under the influence of the electric field force.

[0045] Two brush roller rings 27 are provided, located on the front and rear sides of the reverse electrostatic electrode plate 26, respectively, at the front and rear ends along the yarn travel direction. The brush roller rings 27 are made of conductive nylon bristles, with carbon black added to improve conductivity. The brush makes slight contact with the yarn, with the contact depth controlled at 1-2 mm. Static electricity accumulated on the brush is conducted away through a grounding wire to prevent secondary discharge. The brush roller rings 27 effectively remove tightly adhered impurities from the yarn surface and loosen impurities before the yarn enters the electrostatic field, improving dust removal efficiency.

[0046] The negative pressure collection chamber 25 is located at the bottom of the lower reverse electrostatic electrode plate 26, with its opening facing the yarn and a width of 80mm, covering the yarn travel area. A negative pressure fan 24 is connected to the bottom of the negative pressure collection chamber 25, and the outlet of the negative pressure fan 24 is connected to a dust collection filter bag 23. When the negative pressure fan 24 is working, it generates suction, drawing the lint swept off by the brush roller ring 27 and impurities detached from the yarn by the electrostatic field into the negative pressure collection chamber 25, where they are ultimately collected in the dust collection filter bag 23, achieving centralized treatment of impurities and preventing secondary pollution.

[0047] During operation, the yarn passes through each module sequentially under the traction of the warping machine. First, the pre-electrostatic monitoring module 2 uses three ring-shaped non-contact electric field probes 9 to detect the electrostatic charge distribution along the circumference of the yarn in real time, outputting an electric field strength signal to the control unit. The control unit dynamically adjusts the opening of the proportional control valve 17 and the power of the high-frequency ultrasonic atomizing plate 29 of the liquid phase change adaptive humidification module 4 based on the detection signal, atomizing deionized water into ultrafine particles and uniformly spraying them onto the yarn surface to improve the yarn's conductivity. Subsequently, the yarn enters the eddy current focusing ion neutralization module 6, where positive and negative ions generated by the corona discharge of the ring-shaped ion needle plate 18 are focused and transported to the yarn surface under the guidance of the Coanda effect airflow plate 20, neutralizing the electrostatic charge carried by the yarn. Finally, the yarn enters the electrostatic adsorption dust removal module 7, where, under the action of the high-voltage electrostatic field of the reverse electrostatic electrode plate 26, combined with the mechanical cleaning of the brush roller ring 27 and the suction action of the negative pressure fan 24, dust, lint, and other impurities on the yarn surface are efficiently adsorbed and collected into the dust collection filter bag 23. Through the coordinated operation of the above modules, accurate detection of yarn static electricity, adaptive humidification, efficient neutralization, and thorough dust removal are achieved.
