Description

Technical Field

[0001] This invention relates to the field of static electricity removal devices, specifically a static electricity removal device for use in the cutting and sewing process of textiles. Background Technology

[0002] Before cutting and sewing textiles, the unwinding process generates significant static electricity, sometimes reaching tens of thousands of volts, due to friction between the fabric and the unwinding table. This static electricity can attract dust, cause electric shocks, and even lead to fires. Ionizing air bars are a type of fixed static electricity elimination device, characterized by easy installation, safe and stable operation, and rapid static elimination. Primarily used in industries such as electronics, plastics, screen printing, prepress systems, and image processing, they ionize the air using high-voltage corona discharge to generate positive and negative ions. These ions, combined with airflow, are then transported to the surface of the textile fabric to neutralize the charge, eliminating static electricity generated by friction between the fabric and the unwinding table. This prevents issues such as fraying and cutting blade contamination, thus achieving the desired static electricity elimination effect.

[0003] In the prior art, such as the pulsed ion bar disclosed in CN223402062U, there is an ion bar body with an operation panel on the front. Several knob-type ion needle assemblies are provided, electrically connected to the ion bar body. Each knob-type ion needle assembly includes a protective cylinder with an ion needle disposed in a groove within the cylinder. An insertion head is located at the top of the protective cylinder, and an air inlet is provided on the insertion head. The air inlet and outlet are connected via an air duct. The knob-type ion needle assembly in this document employs a knob-type disassembly design, allowing for quick removal from the bottom of the ion bar body for easy replacement or cleaning maintenance. The protective cylinder has protrusions and an anti-slip surface, and uses a threaded connection, ensuring stable handling and easy rotation for disassembly, thus reducing enterprise costs.

[0004] The aforementioned document addresses the issue of existing air bar ion needles being fixed and difficult to disassemble and replace. However, in actual use, the existing air bar nozzles enhance ion diffusion efficiency through compressed air and are commonly used in high-speed production line dust removal scenarios. The integrated air pipe connector and air outlet adopt a direct airflow design, but the direct airflow is prone to creating a "strong in the middle and weak at the edges" coverage blind zone, making it difficult to penetrate into the fiber gaps inside the fabric to eliminate deep static electricity.

[0005] Therefore, this invention proposes an electrostatic removal device for textile cutting and sewing processes to solve the problem that existing ion blower nozzle assemblies have limited airflow blowing effects, making it difficult for neutralized ions to penetrate the gaps between fibers inside the textile fabric and eliminate deep static electricity. Summary of the Invention

By incorporating an ion neutralization unit in conjunction with an air source unit and a needle tip protection unit, it changes the traditional direct-blowing airflow design, causing the airflow to diffuse in a spiral pattern, avoiding blind spots of "strong coverage in the middle and weak coverage at the edges." Furthermore, through the optimized design of the protective cap mounting plate, the outer hexagonal protective cap, and the inner cylindrical air nozzle assembly, the ion needle tip can simultaneously generate positive and negative ions and a spiral airflow. The spiral airflow forms a dynamic protective layer on the ion needle surface, reducing the direct adhesion of dust, particulate matter, and other impurities to the needle tip, mitigating the decrease in electric field strength caused by contamination. The spiral airflow also possesses self-stabilizing characteristics, resisting external airflow disturbances and maintaining the stability of the ion jet direction, further rapidly neutralizing and preventing surface charge on the fabric, and preventing issues such as fraying. Simultaneously, the combination of the needle tip protection unit and the quick-release unit facilitates the protection and rapid disassembly of the ion needle, making replacement or cleaning maintenance convenient and reducing enterprise costs.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figures 1-17, the present invention provides a technical solution: an electrostatic elimination device for the textile cutting and sewing process, including an electrostatic elimination rod body 1. Left side plates 11 and right side plates 12 are fixedly installed at both ends of the electrostatic elimination rod body 1 respectively. An air source unit 14 is arranged on one side of the right side plate 12. An upper groove plate 2 is fixedly installed at the upper end of the electrostatic elimination rod body 1. Connecting plates 13 are movably installed at both ends of the upper groove plate 2 respectively; among them, the main body of the electrostatic elimination rod body 1 is made of antioxidant aluminum alloy. The air source unit 14 is equipped with a pneumatic pressure regulating valve and an intake throttle valve. A strip groove is opened on the back of the upper groove plate 2 for convenient bolt installation; a lower protection plate 3 is fixedly installed at the lower end of the electrostatic elimination rod body 1. An embedded groove 10 is opened on the inner wall of the electrostatic elimination rod body 1. An embedded air duct 4 is fitted and installed inside the embedded groove 10. An air duct 40 is opened on the inner wall of the embedded air duct 4. One end of the air duct 40 is hermetically connected to the output end of the air source unit 14. Air guiding holes 400 are evenly opened on the lower inner wall of the air duct 40. An ion neutralization unit is arranged inside the air duct 40 and the air guiding holes 400. The ion neutralization unit includes an ion needle 43. The ion needle 43 adopts a tungsten ion emission needle, which has a long service life and is convenient to replace. The ion neutralization unit also includes a circuit board 41 and a spring 42. An upper embedded groove 410 is opened on the upper inner wall of the air duct 40. The circuit board 41 is embedded and installed inside the upper embedded groove 410. The lower surface of the circuit board 41 is fixedly connected to the upper end of the spring 42. The other end of the spring 42 is fixedly connected to a connecting needle sleeve 421. The inner surface of the connecting needle sleeve 421 is slidably installed on the outer surface of the ion needle 43, and the spring 42 is slidably sleeved on the outer surface of the upper side of the ion needle 43; The lower ends of two groups of lower protection plates 3 are movably installed with a tip protection unit. The tip protection unit includes a protection cap mounting plate 5, an external hexagonal protection cap 6 and an inner cylindrical air nozzle kit 61. The external hexagonal protection cap 6 is integrally formed by a threaded cylinder and a hexagonal body. A threaded groove is opened on the inner surface of the center of the protection cap mounting plate 5. The inner surface of the threaded groove is threadedly connected to the outer surface of the threaded cylinder; An installation groove 50 is opened on the inner wall of the protection cap mounting plate 5. The installation groove 50 is in a "冂" - shaped groove structure; In this embodiment, the textile fabric is conveyed by an unwinding device in front of the textile cutting table. The static elimination rod 1 is installed as a whole above the cutting table or sewing machine. The static elimination rod 1 is connected to a sensor, which can monitor the static electricity on the surface of the textile fabric in real time and feed the signal back to the control system of the device. When eliminating static electricity on the surface of the textile fabric, the power supply of the device is turned on, the air source unit 14 is connected to the air source, the air source is conveyed by the embedded air duct 4, and the air is discharged to the ion needle 43 through several air guide holes 400. At this time, the ion neutralization unit composed of the circuit board 41, spring 42 and ion needle 43 forms a passage. Under the action of the current, the tip of the ion needle 43 generates positive and negative ions. These positive and negative ions are all neutralized by the spiral diffusion airflow. The air is evenly blown onto the surface of the textile fabric, where it neutralizes the static charge on the fabric surface, thus effectively eliminating static electricity. Combined with the air source unit 14 and the needle tip protection unit, the traditional direct-blowing airflow design is changed to a spiral diffusion airflow. This spiral diffusion allows for a more even distribution of positive and negative ions generated at the tip of the ion needle 43 to the surface of the textile fabric. When the static-laden fabric surface comes into contact with these positive and negative ions, the ions neutralize the static charge on the fabric surface. Specifically, if the fabric surface is positively charged, the negative ions will combine with it; if the fabric surface is negatively charged, the positive ions will neutralize it. Through this neutralization process, the static charge on the textile fabric surface is effectively eliminated, thus achieving the purpose of static electricity removal. It is worth noting that the circuit board 41, as a key conductive component, is embedded in the upper groove 410 on the inner wall of the air duct 40. When the power is turned on, the entire circuit system starts to work. Since the circuit board 41, spring 42 and ion needle 43 are connected in sequence to form a circuit, the current can pass through the unit smoothly. At this time, the ion needle 43 is a tungsten ion emitting needle. Tungsten material has excellent conductivity and high temperature resistance, corrosion resistance and other properties, and can maintain stable performance during long-term use. Under the action of current, the tip of the ion needle 43 will form an extremely strong electric field. Neutral molecules in the air will be ionized into positive ions and negative ions under the action of the strong electric field.

[0022] Example 2, see attached document Figures 1-17 Based on Example 1, in order to achieve the change in the airflow path at the tip of the ion needle 43: The inner cylindrical air nozzle assembly 61 consists of a cylindrical part 611, a lower connecting part 612, an inner conical part 613, and a central support part 614. The outer surface of the cylindrical part 611 is movably connected to the inner annular surface of the threaded cylinder, and the inner annular surface of the cylindrical part 611 is provided with an Archimedean spiral groove 6110. The upper surface of the lower connecting part 612 is fixedly connected to the lower end of the cylindrical part 611. The lower inner wall of the lower connecting part 612 is provided with evenly spaced oblique exhaust holes 6120, and multiple sets of oblique exhaust holes 6120 are arranged in a circular array about the central axis of the lower connecting part 612. The inner conical part 613 is fixedly installed on the inner annular surface of the lower connecting part 612. The inner wall of the inner cone 613 is evenly provided with air outlet arc grooves 6130; the upper end of the inner cone 613 is fixedly connected with a threaded connecting sleeve 6131, the inner surface of the threaded connecting sleeve 6131 is threadedly connected to the lower outer surface of the central support 614, the outer ring surface of the central support 614 is provided with an Archimedean spiral convex pattern 6141, and the Archimedean spiral convex pattern 6141 is integrally formed with the central support 614; the central inner surface of the central support 614 is provided with a central groove 6140, the inner ring surface of the central groove 6140 is fixedly installed with an insulating rubber sleeve, and the inner surface of the insulating rubber sleeve is movably connected to the outer surface of the ion needle 43; In this embodiment, reference Figures 2-6 As shown, the outer hexagonal protective cap 6 and the inner cylindrical air nozzle kit 61 are structurally optimized. When the airflow enters the inner cylindrical air nozzle kit 61 through several air guide holes 400, the airflow forms a three-dimensional flow field under the interaction of the Archimedean spiral groove 6110 and Archimedean spiral convex pattern 6141 on the inner side of the cylindrical part 611. At this time, the airflow forms a rotating vortex. Then, through the design of the inwardly narrowing inner cone part 613, the rotating vortex is ejected through several arrayed air outlet arc grooves 6130, thus contacting the tip of the ion needle 43, accelerating the diffusion and uniform distribution of neutralized ions, and at the same time, it can assist in blowing away the dust accumulated on the needle tip, ensuring that the ion needle 43 always remains in good condition. The working state is to avoid the performance being affected by dust adhesion; it is worth noting that part of the airflow in the rotating vortex will be discharged through the evenly opened oblique exhaust holes 6120 on the inner wall of the lower connecting part 612. At this time, the oblique exhaust holes 6120 can guide the airflow to superimpose with the airflow swirling out of the air outlet arc groove 6130 to form a stable three-dimensional spiral flow field. When the ion airflow flows through the oblique exhaust holes 6120, positive and negative ions form a cross electric field on the inner side of the hexagonal part, so that the ion flow diffuses evenly along the inner wall of the hexagonal part, avoiding the "strong in the center and weak at the edge" distribution caused by direct blowing, further improving the neutralization stability, ensuring penetration into the fiber gaps inside the fabric, eliminating deep static electricity, and improving the processing efficiency and quality of textiles; When assembling the outer hexagonal protective cap 6, the inner cylindrical air nozzle kit 61, and the protective cap mounting plate 5, hold the hexagonal part of the outer hexagonal protective cap 6 and tighten the threaded column to fit the threaded groove in the center of the protective cap mounting plate 5. At this time, the central groove 6140 in the center of the central support part 614 is aligned with the ion needle 43. During the tightening process, the ion needle 43 passes through its center. At this time, the top side of the annular cavity formed by the inner side of the cylindrical part 611 and the outer ring of the central support part 614 is in contact with the outlet of the air guide hole 400. It is worth noting that the insulating sleeve installed in the center of the central support part 614 contacts the outer wall of the ion needle 43, which can not only limit and protect the ion needle 43, but also achieve a stabilizing effect on the ion needle 43. In addition, the central support part 614 stands upright in the center of the cylindrical part 611 and cooperates with the Archimedes spiral groove 6110 to achieve auxiliary airflow guidance, realizing the effect of multiple uses in one piece.

[0023] Example 3, refer to Appendix Figures 1-17 Based on Embodiment 2, in order to achieve stability in the installation between the inner cylindrical air nozzle assembly 61 and the outer hexagonal protective cap 6: A flange is provided at one end of the cylindrical part 611 away from the lower connecting part 612. A spring wire is fixedly connected to the upper surface of the flange. An annular limiting groove is provided on the upper inner wall of the outer hexagonal protective cap 6. The inner surface of the annular limiting groove is slidably connected to the outer ring surface of the flange, and the end of the spring wire away from the flange is fixedly connected to the top surface of the inner cavity of the annular limiting groove. In this embodiment, by setting a flange on the top side of the cylindrical part 611 and connecting it to the outer hexagonal protective cap 6 via a spring wire, a unique and effective stable installation structure is formed. In actual use, when the device is subjected to external forces such as vibration or collision, the flange slides in the annular limiting groove, and the spring wire provides tension, which can effectively absorb and disperse vibration energy, ensuring that the inner cylindrical air nozzle kit 61 is always firmly installed on the outer hexagonal protective cap 6 without loosening or displacement.

[0024] Example 4, see attached document Figures 1-17 Based on Embodiment 3, in order to achieve rapid assembly between several protective cap mounting plates 5 and lower protective plates 3: Both sets of lower guard plates 3 have straight grooves 30 on their lower inner walls, and circular locking grooves 301 are formed through the upper ends of the straight grooves 30. A quick-installation unit is provided inside the mounting groove 50. The quick-installation unit includes an elastic groove plate 51, which is embedded in the central inner wall of the mounting groove 50. Swing arm plates 52 are fixedly connected to both ends of the elastic groove plate 51. The swing arm plates 52 are rotatably installed inside the mounting groove 50 via pins. The swing arm plates 52 are integrally formed from a plate and a circular body, and the outer surface of the circular body is flush with the circular locking groove 301. The inner surface is movable. An elastic contact piece 53 is fixedly connected to one side of the plate. An elastic block 531 is fixedly installed on the inner side of the elastic contact piece 53. A force-receiving push block 1 54 and a force-receiving push block 2 55 are slidably installed on the lower surface of the elastic groove plate 51. A magnetic block 1 and a magnetic block 2 are respectively provided at the center ends of the force-receiving push block 1 54 and the force-receiving push block 2 55. The magnetic block 1 and the magnetic block 2 are two magnetic poles that attract each other. The ends of the force-receiving push block 1 54 and the force-receiving push block 2 55 that are away from the magnetic block 1 and the magnetic block 2 respectively move against the lower side of the swing arm plate 52. In this embodiment, when assembling the protective cap mounting plate 5 as a whole, please refer to... Figures 2-6 , Figure 7 , Figure 8 and Figure 17 As shown, align the protective cap mounting plate 5 with the notch at the bottom of the lower protective plate 3 and push it upwards. During the pushing process, the circular bodies of the two sets of relatively distributed swing arm plates 52 abut against the inner wall of the straight groove 30. Then, during the upward pushing process, the circular bodies reach the circular locking groove 301 and lock. At this time, under the elastic action of the elastic contact piece 53 and the elastic block 531, the swing arm plate 52 forms a locked state between the circular body and the circular locking groove 301. When it is necessary to unlock it, place two fingers on the force-bearing push block one. Within the grooves of 54 and the second force-bearing push block 55, the two fingers expand outward, applying a force greater than the attraction of the first and second magnetic blocks. At this time, the first force-bearing push block 54 and the second force-bearing push block 55 move towards the lower end of the swing arm plate 52, and apply an external force inward to the end of the swing arm plate 52 away from the circular body. The swing arm plate 52 forms a lever action under the connection of the pin shaft. At this time, the circular body is released from the restriction between the circular locking groove 301, and then the entire protective cap mounting plate 5 can be quickly disassembled by pulling it down.

[0025] The working principle and usage process of this invention are as follows: In actual use, firstly, the outer hexagonal protective cap 6, the inner cylindrical air nozzle kit 61, and the protective cap mounting plate 5 are assembled. Holding the hexagonal part of the outer hexagonal protective cap 6, the threaded column is fitted and tightened to match the threaded groove in the center of the protective cap mounting plate 5. Subsequently, the protective cap mounting plate 5, which is equipped with the outer hexagonal protective cap 6 and the inner cylindrical air nozzle kit 61, is assembled with the lower guard plate 3. The protective cap mounting plate 5 is aligned with the notch at the bottom of the lower guard plate 3 and pushed upward. During the pushing process, the circular bodies of the two sets of relatively distributed swing arm plates 52 abut against the inner wall of the straight groove 30. Then, during the upward pushing process, the circular bodies reach the circular locking groove 301 and lock. At this time, under the elastic action of the elastic contact piece 53 and the elastic block 531, the swing arm plates 52 form a locked state between the circular bodies and the circular locking groove 301. In the locked state, the central groove 6140 of the central support 614 is aligned with the ion needle 43, which passes through its center. At this time, the top side of the annular cavity formed by the inner side of the cylindrical part 611 and the outer ring of the central support 614 is connected to the outlet of the air guide hole 400. When eliminating static electricity on the surface of the textile fabric, the power supply of the equipment is turned on, the air source unit 14 is connected to the air source, the air source is transported by the embedded air duct 4, and the air is discharged to the ion needle 43 through several air guide holes 400. At this time, the ion neutralization unit composed of the circuit board 41, the spring 42 and the ion needle 43 forms a passage. Under the action of the current, the tip of the ion needle 43 generates positive and negative ions. These positive and negative ions are evenly blown to the surface of the textile fabric under the action of the spiral diffusion airflow, and neutralize the static charge on the surface of the fabric, thereby effectively eliminating static electricity.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
