DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 The wire braiding device for cable production in the embodiment includes a rack 1 and a braiding assembly 2 installed above the rack 1. The braiding assembly 2 is an existing assembly and can braid multiple metal wires. Since the braiding assembly 2 is not the object to be protected in the present application, it will not be described or limited. A dust suction mechanism 3 is arranged below the rack 1. The dust suction mechanism 3 includes an insulation box 301, air outlets 302 arranged at the bottom of the insulation box 301, and four dust suction cylinders 304 communicated with the top of the insulation box 301. The insulation box 301 is fixedly connected below the rack 1 through the four dust suction cylinders 304. The four dust suction cylinders 304 are respectively arranged at the four corners of the rack 1. By limiting the positions of the dust suction cylinders 304, the metal dust generated during the braiding process of the braiding assembly 2 can be collected in multiple directions. An air extractor 303 is installed on the inner bottom wall of the insulation box 301. When the air extractor 303 is started, the metal dust generated during the braiding process of the braiding assembly 2 can be sucked into the insulation box 301 through the four dust suction cylinders 304 for collection and treatment, thereby avoiding the safety problems caused by the overflow of metal dust.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4The outer surface of the insulation box 301 is provided with a high-voltage power supply 306, and the inner wall of the insulation box 301 is fixedly connected with an insulation support plate 307. In order to prevent breakdown or creeping phenomenon caused by long-term operation, the withstand voltage level of the insulation support plate 307 can be improved. A plurality of discharge electrodes 308 are mounted on the surface of the insulation support plate 307, and the tips of the discharge electrodes 308 are downward. The high-voltage power supply 306 is electrically connected with the plurality of discharge electrodes 308 through wires. By arranging a plurality of discharge electrodes 308, the situation that the adsorption efficiency is reduced due to uneven field intensity of a single electrode can be avoided. The bottom surface of the insulation support plate 307 is suspended with a metal mesh plate 309 through an insulating column, and the metal mesh plate 309 is in a parallel state with the discharge electrode 308. The mesh density of the metal mesh plate 309 is moderate, such as 0.5-2mm interval, so as to ensure that the airflow flows smoothly and increase the adsorption area. One side of the metal mesh plate 309 is provided with a grounding wire 310. The output end of the grounding wire 310 penetrates through the insulation box 301 and extends to the outside of the insulation box 301. By arranging the grounding wire 310, the metal mesh plate 309 can be conveniently connected with the grounding end, so as to conveniently form a counter electrode of the electric field.

[0032] It should be noted that the high-voltage power supply 306 provides a high-voltage difference between the discharge electrode 308 and the metal mesh plate 309, which is used to generate an electrostatic field. In this way, when the high-voltage power supply 306 is turned on, a voltage can be applied to the discharge electrode 308 through the wire. Under the action of high voltage, the electric field can be released to ionize the surrounding air to form charged particles. The metal mesh plate 309 provides a surface for adsorbing particles, and at the same time forms a counter electrode of the electric field through the grounding wire 310. In this way, the metal dust can be adsorbed in the metal mesh plate 309, solving the problem of metal dust overflow.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 The inner wall of the insulation box 301 is fixedly connected with a filter plate 305, and the filter plate 305 is located above the metal mesh plate 309. By arranging the filter plate 305, larger particles can be preliminarily filtered, and smaller metal dust can be adsorbed on the metal mesh plate 309, realizing the effect of multi-layer filtering and collecting. One side of the insulation box 301 is provided with an insulation cover 4 through an insulating bolt. By arranging the insulation cover 4, the staff can conveniently clean the metal dust collected in the insulation box 301 regularly, which is beneficial to the reuse of the dust collection mechanism 3. The inner bottom wall of the insulation box 301 is fixedly connected with a protection plate 311, which is located directly above the exhaust fan 303 and can provide protection for the exhaust fan 303. When the metal mesh plate 309 is cleaned, the metal dust can be effectively prevented from falling into the exhaust fan 303 to affect the operation of the exhaust fan 303, thereby prolonging the service life of the exhaust fan 303.

[0034] Please refer to Figure 1The upper surface of the rack 1 is fixedly connected with a dust cover 5, the front surface of the dust cover 5 is provided with two cover doors 6, the braiding assembly 2 is located inside the dust cover 5 and the cover doors 6, the back surface of the dust cover 5 is provided with a ventilation opening, which is not marked in the figure, so that the metal dust can be effectively prevented from spreading outward, and the air circulation effect can be formed with the dust suction mechanism 3, and the dust collection effect of the dust suction mechanism 3 is optimized, and the outer surface of each cover door 6 is fixedly connected with a handle 7, so that the cover door 6 can be conveniently pulled, and the operation process is optimized.

[0035] In the embodiment, the metal wire braiding device for cable production utilizes the electrostatic adsorption principle, generates a high-voltage electrostatic field, and causes charged particles such as metal dust or particulate matter to be adsorbed and collected under the action of electric field force, so as to purify air or capture particulate matter. During work, the air blower 303 and the high-voltage power supply 306 can be started. When the air blower 303 is started, the metal dust generated by braiding above the rack 1 can be sucked through the dust suction cylinder 304. The metal dust and particulate matter can be preliminarily filtered through the filter plate 305. The opening of the high-voltage power supply 306 can apply voltage to the plurality of discharge electrodes 308 through the wires, release the electric field, ionize the surrounding air to form charged particles, and the metal mesh plate 309 is connected to the ground end through the grounding wire 310 to form the opposite pole of the electric field, so that the metal dust can be adsorbed in the metal mesh plate 309, effectively solving the problem of metal dust overflow.

[0036] The working principle of the above embodiment is as follows: when in use, the two cover doors 6 are closed, the metal wire is braided by the braiding assembly 2, the air blower 303 and the high-voltage power supply 306 are started, and the grounding wire 310 is connected to the ground end. When the air blower 303 is started, the metal dust generated in the braiding process of the braiding assembly 2 can be sucked into the insulating box 301 through the four dust suction cylinders 304. The foreign matter in the insulating box 301 can be preliminarily filtered through the filter plate 305. The opening of the high-voltage power supply 306 can transmit high-voltage signals to the discharge electrode 308 through the insulating wire. The discharge electrode 308 generates a strong electric field, ionizes the surrounding air to form charged particles, and the metal mesh plate 309 is located below the discharge electrode 308 and is grounded through the grounding wire 310 to form the opposite pole of the electric field. When the charged metal dust particles such as metal dust enter the electric field area, they will be attracted and finally adsorbed on the metal mesh plate 309, completing the collection of metal dust. In order to ensure the air flow in the dust cover 5, a ventilation opening is formed on the back surface of the dust cover 5. The outside air can enter the inside of the dust cover 5 through the ventilation opening. The metal dust in the air can be adsorbed on the metal mesh plate 309, and the purified gas can be discharged to the outside through the air outlet 302. Therefore, the metal dust generated during the braiding of the braiding assembly 2 will not overflow, improving the safety factor during work and being more practical.
