[0001] The utility model belongs to the field of textile processing auxiliary equipment, and particularly relates to an electrostatic elimination device and a drafting bracket with an electrostatic elimination function. Background Art
[0002] A fancy twisting machine is a machine that can produce fancy yarns of various styles and structures. When feeding yarn raw materials into the fancy twisting machine, drafting rollers are required. Since the surface of the roller is coated with nitrile rubber and the upper roller is usually friction-driven by the lower roller, the yarn raw materials are extremely likely to generate a large amount of static electricity due to friction during traction feeding. After the yarn raw materials with a large amount of static electricity are fed into the fancy twisting machine, the fiber arrangement will be disordered, resulting in problems such as decreased yarn strength, sparseness, and hairiness. Before the present utility model was made, our enterprise increased the humidity of the production environment by sprinkling water or using a humidifier to reduce the generation of static electricity, but the effect was limited. Therefore, there is an urgent need for another efficient electrostatic elimination device. Summary of the Utility Model

[0019] Reference Figures 1 to 3An electrostatic eliminator 10 includes an insulating block 3, a first clamping block 1, a second clamping block 2, and ionization needles. A horizontally arranged discharge channel 301 is formed on the insulating block 3, and ionization needle holes 302 are formed on the inner wall of the discharge channel 301. Ionization needles are arranged in the ionization needle holes 302 and are connected to a high-voltage power generator through wires 5. A plurality of discharge through holes 303 are further formed on the side surface of the insulating block 3, and the discharge through holes 303 communicate with the discharge channel 301.
[0020] The first clamping block 1 and the second clamping block 2 are arranged in parallel and fixedly connected to the bottom surface of the insulating block 3. An installation gap is left between the first clamping block 1 and the second clamping block 2 and is arranged vertically. Installation holes are formed on the first clamping block 1 and the second clamping block 2.
[0021] Under the action of the high-voltage power supply, the high-voltage corona discharge at the tip of the ionization needle ionizes air into a large number of positive and negative ions. After a large number of positive and negative ions enter the discharge channel 301 of the insulating block 3, they can gush out from both ends of the discharge channel 301 and the discharge through holes 303 on the side surface of the insulating block 3, and then contact the surrounding yarn raw materials, thereby neutralizing and eliminating the static electricity on the yarn raw materials. The settings of the discharge channel 301 and the discharge through holes 303 of the insulating block 3 can guide and control the electrostatic elimination range of the ionization needles, enabling the positive and negative ions to effectively contact the yarn raw materials.
[0022] Reference Figure 2 and Figure 3 A fixing block 4 is fixedly connected between the included angle of the insulating block 3 and the second clamping block 2. A needle-passing hole 401 is formed at the center of the fixing block 4. The ionization needle hole 302 on the inner wall of the discharge channel 301 communicates with the needle-passing hole 401 and is on the same axis. The ionization needle passes through the needle-passing hole 401 of the fixing block 4 and is placed in the ionization needle hole 302 of the insulating block 3. The ionization needle has an interference fit with the needle-passing hole 401. A wire groove 402 is formed on one side of the fixing block 4, and a part of the wire 5 of the ionization needle is clamped in the wire groove 402. Such an installation method of the ionization needle and the wire 5 through the fixing block 4 can prevent the ionization needle from shaking during operation.
[0023] Reference Figure 4 A drafting support with an electrostatic elimination function, including a support bar 21, a plurality of sliver bundles 22, and a plurality of the above-mentioned electrostatic eliminators 10. The plurality of sliver bundles 22 are installed on the support bar 21 at intervals. An electrostatic eliminator 10 is arranged between two adjacent sliver bundles 22. The opening end of the discharge channel 301 of the electrostatic eliminator 10 is arranged opposite to the sliver bundle 22. The discharge through holes 303 on the side surface of the insulating block 3 are inclined holes and face the rear of the sliver bundle 22. In this way, a large number of positive and negative ions ionized and released by the electrostatic eliminator 10 will rush towards the sliver bundle 22 and the rear of the sliver bundle 22, accurately and efficiently neutralizing and eliminating the static electricity of the yarn raw materials in the sliver bundle 22 and the yarn raw materials passing through the sliver bundle 22.
[0024] The static eliminator 10 is clamped on the support bar 21 through the first clamping block 1 and the second clamping block 2, that is, the support bar 21 is located between the first clamping block 1 and the second clamping block 2. Mounting holes are also provided at corresponding positions of the support bar 21 in the first clamping block 1 and the second clamping block 2. The first clamping block 1 and the second clamping block 2 of the static eliminator 10 are fixedly connected to the support bar 21 through screws or bolt-nut fasteners. In this way, the static eliminator 10 can be stably and reliably mounted on the support bar 21 of the drafting support. The drafting support is located beside the drafting roller. The yarn raw material with static electricity generated by friction traction of the drafting roller can eliminate static electricity after passing through the sliver bundle 22 of the drafting support and is finally fed into the fancy twisting machine. This static elimination method is accurate, convenient and efficient.
