Description

Technical Field

[0001] This utility model relates to the field of yarn static electricity elimination technology, specifically to a static electricity elimination device for warping machines used in the preparation of warp-knitted fabrics. Background Technology

[0002] Currently, warping is a process of winding a certain number of warp yarns parallel to each other on a warp beam or weaving beam according to a specified length and width. Warping machines used for sizing and threading warp yarns can be divided into two main categories: one is the traditional roller-type friction drive warping machine, and the other is the new type of warping machine with direct drive of the warping beam. When the yarn moves on the warping machine, the yarn rubs against the roller, and static electricity is generated on the yarn. Static electricity will attract dust, so a static electricity elimination device is needed.

[0003] Chinese patent CN217479653U discloses a warping machine for antistatic yarn, relating to the field of warping machine technology. This application includes a warping machine body, with a yarn separating plate fixedly connected to one top end and a guide roller fixedly connected to the other top end. A take-up cavity is opened on one side of the warping machine body, and a take-up drum is installed on one side of the warping machine body, the take-up drum being installed inside the take-up cavity. A tensioning assembly is installed in the middle of the top of the warping machine body, and an antistatic component for eliminating static electricity is fixedly connected to the tensioning assembly. This patent generates ion wind through an ion wind bar and blows the ion wind onto the yarn. The ion wind neutralizes the positive and negative charges on the yarn, achieving the effect of removing static electricity.

[0004] While this existing technology generates ion wind using an ion bar, which then blows onto the yarn to neutralize positive and negative charges, its static-eliminating efficiency is often affected by various factors, such as the wind speed, direction, and ion concentration, as well as the yarn's material, diameter, and velocity. Changes in these factors can lead to unstable static-eliminating effects, and in some cases, the ion wind may not completely neutralize the static charge on the yarn. Utility Model Content

[0005] The purpose of this invention is to provide a static electricity elimination device for warping machines used in the preparation of warp-knitted fabrics. By providing a first static electricity elimination component, the static electricity of the yarn can be discharged, thus achieving complete static electricity elimination.

[0006] To address the problems of existing technologies, this utility model provides a static electricity elimination device for warping machines used in the preparation of warp-knitted fabrics. The device is characterized by: a support plate, a receiving cavity at the top center of the support plate, a sliding groove on the receiving cavity, a first static electricity elimination component for eliminating static electricity on the yarn slidably disposed in the receiving cavity, a second static electricity elimination component for eliminating static electricity on the yarn also disposed on the support plate, and a lifting component for moving the first static electricity elimination component up and down between the receiving cavity and the first static electricity elimination component.

[0007] Preferably, the top of the first static elimination component has a plurality of support frames distributed along its length, and each support frame is rotatably provided with a guide wheel on its top, and the guide wheel is provided with a groove for preventing yarn deviation.

[0008] Preferably, the first static elimination component includes a lifting plate, on which a first conductive block is fixed by bolts. The bottom end of the first conductive block is connected to a first wire for conducting electricity, and one end of the first wire is connected to a second guide block.

[0009] Preferably, the second static electricity elimination component includes an air duct disposed directly above the first static electricity elimination component, a corona discharger for discharge is disposed in the air duct along its length, and a through groove for air to pass through is formed at the center of the bottom of the air duct along its length.

[0010] Preferably, the second static electricity elimination component includes a fan mounted on the top of the support plate, and the second static electricity elimination component includes a duct, one end of which is connected to the air outlet of the fan, and the other end of which is connected to an air duct.

[0011] Preferably, the lifting assembly includes two connecting rods symmetrically positioned relative to the center of the first static elimination assembly. The connecting rods are disposed in the receiving cavity, with one end of the connecting rod movably disposed at the bottom of the lifting plate and the other end of the connecting rod movably disposed with a sliding member. The lifting assembly also includes a driving mechanism for driving the sliding member to move along the length direction of the lifting plate.

[0012] Preferably, the driving mechanism includes a rotary drive component fixed outside the receiving cavity, and the output end of the rotary drive component is connected to a lead screw, which is threadedly connected to a slide.

[0013] Preferably, the bottom of the support plate is also provided with mounting parts around the perimeter to facilitate the installation of the support plate on the warping machine.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This application achieves static electricity elimination by setting a first static electricity elimination component. The first static electricity elimination component is designed with a support frame, and a guide wheel is equipped on the top of the support frame. A groove is formed on the guide wheel, and the yarn moves within the groove and remains in contact with the guide wheel. During contact, the charge on the yarn is transferred to the guide wheel, and then transmitted to the first conductor through a lifting plate. Simultaneously, a second guide block can be connected to the ground wire of the warping machine, allowing the charge to be conducted to the ground, thereby effectively eliminating static electricity on the yarn;

[0016] 2. To ensure that the yarn always maintains contact with the guide wheel, this application also includes a tension adjustment mechanism. By activating the rotary drive, the lead screw rotates, which in turn moves the sliding component. The movement of the sliding component causes the connecting rod to move, thereby raising the lifting plate. When the yarn tension is insufficient and becomes too loose, the guide wheel moves upward to tension the yarn. This design avoids the problem of poor contact between the yarn and the guide wheel due to excessively loose yarn, thus affecting the static electricity elimination effect.

Detailed Implementation

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-6 As shown, this utility model provides a static electricity elimination device for warp knitting fabric preparation using a warping machine, including a support plate 1. A receiving cavity 12 is provided at the top center of the support plate 1. A sliding groove 121 is provided on the receiving cavity 12. A first static electricity elimination component 13 for eliminating static electricity on the yarn is slidably disposed in the receiving cavity 12. A second static electricity elimination component 14 for eliminating static electricity on the yarn is also provided on the support plate 1. The receiving cavity 12 and the first static electricity elimination component 13 are also provided with a lifting component 15 for moving the first static electricity elimination component 13 up and down. The lifting component 15 can be driven by mechanical, hydraulic or pneumatic means, and the height of the first static electricity elimination component 13 can be adjusted by controlling its movement.

[0026] The first static eliminator 13 has several support frames 132 distributed along its length on its top. Each support frame 132 has a guide wheel 1321 rotatably mounted on its top. The guide wheel 1321 has a groove 13211 for preventing yarn deviation. The guide wheel 1321 guides the yarn through. The groove 13211 on the guide wheel 1321 ensures that the yarn does not deviate during transmission and maintains a stable path. The first static eliminator 13 includes a lifting plate 131. A first conductive block 133 is fixed to the lifting plate 131 by bolts. The bottom end of the first conductive block 133 is connected to a first conductive wire 134, and one end of the first conductive wire 134 is connected to a second guide block 1341. The lifting plate 131, as the carrier of the entire first static eliminator 13, moves up and down in the receiving cavity 12 via the lifting assembly 15.

[0027] In use, the yarn moves within the groove 13211 and remains in contact with the guide wheel 1321. During this contact, the charge on the yarn is transferred to the guide wheel 1321 and then transmitted to the first conductor 134 via the lifting plate 131. Simultaneously, the second guide block 1341 can be connected to the ground wire of the warping machine, allowing the charge to be conducted to the ground, thereby effectively eliminating static electricity on the yarn.

[0028] The second static electricity elimination component 14 includes an air duct 141 positioned directly above the first static electricity elimination component 13. A corona discharger 1411 for discharge is disposed along the length of the air duct 141, and the corona discharger 1411 is a key component for static electricity elimination. When energized, the corona discharger 1411 generates corona discharge, ionizing the air within the air duct 141 to form charged particles. A through-slot for airflow is formed at the center of the bottom of the air duct 141 along its length. The second static electricity elimination component 14 includes a fan 142 mounted on the top of the support plate 1, and an air duct 1421. One end of the air duct 1421 is connected to the air outlet of the fan 142, and the other end of the air duct 1421 is connected to the air duct 141.

[0029] The corona discharger 1411 begins to operate. By energizing the corona discharger 1411, it generates positive and negative ions. Simultaneously, the fan 142 is activated, blowing air into the air duct 141, which in turn blows the positive and negative ions onto the yarn to neutralize the positive and negative charges on the yarn.

[0030] The first static eliminator 13 and the second static eliminator 14 work together to eliminate static electricity on the yarn. The first static eliminator 13 eliminates static electricity through direct contact with the yarn, while the second static eliminator 14 eliminates static electricity through the ionization of air and airflow. Using them together further improves the static electricity elimination effect.

[0031] refer to Figure 6 As shown, the lifting assembly 15 includes two connecting rods 153 symmetrically positioned relative to the center of the first static elimination assembly 13. The connecting rods 153 are disposed within the receiving cavity 12. One end of each connecting rod 153 is movably disposed at the bottom of the lifting plate 131, and the other end of each connecting rod 153 is movably disposed with a slider 1521. The lifting assembly 15 also includes a drive mechanism for driving the slider 1521 to move along the length of the lifting plate 131. The drive mechanism includes a rotary drive member 151 fixed outside the receiving cavity 12. The output end of the rotary drive member 151 is connected to a lead screw 152, which is threadedly connected to the slider 1521. Mounting members 11 are also provided around the bottom of the support plate 1 to facilitate mounting the support plate 1 onto the warping machine.

[0032] By activating the rotary drive 151, the lead screw 152 is rotated, which in turn moves the slider 1521. The movement of the slider 1521 causes the connecting rod 153 to move, thereby raising the lifting plate 131. When the yarn tension is insufficient and becomes too loose, the guide wheel 1321 will move upward to tension the yarn. This design avoids the problem of poor contact between the yarn and the guide wheel 1321 due to excessively loose yarn, which would affect the static elimination effect.

[0033] Working Principle: In operation, the yarn is first fixed to the warping machine, ensuring it is engaged in the yarn groove 13211. As the yarn moves within the groove 13211, the corona discharger 1411 begins operation. By energizing the corona discharger 1411, positive and negative ions are generated. Simultaneously, the fan 142 is activated, blowing air into the air duct 141, which in turn blows the positive and negative ions onto the yarn to neutralize the positive and negative charges on it. To fully eliminate static electricity on the yarn, it remains in contact with the guide wheel 1321. During this contact, the charge on the yarn is transferred to the guide wheel 1321 and then transmitted to the first conductor 134 via the lifting plate 131. Simultaneously, the second guide block 1341 is connected to the ground wire of the warping machine, allowing the charge to be conducted to the ground, effectively eliminating static electricity on the yarn. To ensure the yarn remains in contact with the guide wheel 1321, a tension adjustment mechanism is also designed. By activating the rotary drive 151, the lead screw 152 rotates, which in turn moves the slider 1521. The movement of the slider 1521 causes the connecting rod 153 to move, thereby raising the lifting plate 131. When the yarn tension is insufficient and becomes too loose, the guide wheel 1321 will move upward to tension the yarn. This design avoids the problem of poor contact between the yarn and the guide wheel 1321 due to excessively loose yarn, which would affect the static elimination effect.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
