Description

Technical Field

[0001] This utility model relates to a device for cleaning bare enameled wires. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer demands is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal properties.

[0003] During the drawing process of bare enameled wire, the bare wire comes into contact with the drawing fluid, resulting in residual drawing fluid, metal powder generated during the drawing process, and some compound contaminants adhering to the surface. These impurities reduce the adhesion of the bare wire surface, leading to the removal of these deposits during subsequent processing. Therefore, bare wires must be cleaned before enameling. While existing conventional bare wire cleaning devices can quickly clean enameled wires, they still have the following problems: First, traditional cleaning devices may only involve immersion in a single cleaning tank or simple wiping, failing to thoroughly remove stubborn oil, oxide layers, or fine impurities from the bare wire surface, easily leading to cleaning dead zones; Second, many devices use hard, sharp-edged guide wheels or wire guide holes, which can easily scratch the soft copper surface of the bare wire during guidance and cleaning, creating burrs and severely affecting the subsequent enameling quality; Third, unreasonable guide wheel design in traditional cleaning devices can cause the bare wire to jump, shake, or experience uneven tension during operation, not only affecting the cleaning effect but also potentially causing wire breakage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a device for cleaning bare enameled wires.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A bare enameled wire cleaning device includes a cleaning tray, a wire guiding mechanism mounted on the cleaning tray, and bare wires passing through the wire guiding mechanism into the cleaning tray. The wire guiding mechanism includes a support frame fixed to the cleaning tray by screws, and wire guide frames arranged at equal intervals and fixed to the support frame by bolts. The wire guide frames include a crossbar fixed to the support frame by bolts, a first wire guide rod fixedly mounted below one end of the crossbar and extending into the cleaning tray, a first wire guide wheel and a second wire guide wheel fixedly mounted below the crossbar, a bare wire wiping assembly fixedly mounted below the crossbar and located between the first wire guide wheel and the second wire guide wheel, a second wire guide rod fixedly mounted below the other end of the crossbar and extending into the cleaning tray, and a bare wire cleaning block fixedly mounted to the middle of the outer side of the second wire guide rod by bolts.

[0006] Preferably, both ends of the crossbar are bent downwards and have wire wheel mounting ears. The wire inlet wheel is mounted on the wire wheel mounting ear at one end of the crossbar and is used to clean the wires with the first wire guide rod. The wire outlet wheel is mounted on the wire wheel mounting ear at the other end of the crossbar and is used to guide the wires out with the second wire guide rod.

[0007] Preferably, a first lead rod guide wheel is installed at the lower end of the first lead rod.

[0008] Preferably, the bare wire wiping assembly includes a mounting plate, an upper through-mount stud welded above the mounting plate and fixed by a nut after passing through a crossbar, a lower through-mount stud welded below the mounting plate, a lower sponge wiping plate fixed by a nut on the lower through-mount stud, and an upper sponge wiping plate that mates with the lower sponge wiping plate and is fixed by a nut on the lower through-mount stud.

[0009] Preferably, a second guide wheel is installed at the lower end of the second guide rod.

[0010] Preferably, the bare wire cleaning block includes a cleaning block body fixed to the second lead rod by bolts, a bent end integrally formed with the cleaning block body and having a round hole, a steel pipe embedded in the round hole of the bent end, and a sponge sleeve inserted inside the steel pipe.

[0011] The beneficial effects of this utility model are as follows: 1. The dual cleaning station uses a bare wire wiping component and a bare wire cleaning block. In the first process, the upper and lower sponge plates perform strong squeezing and thorough wiping to remove most of the contaminants. In the second process, the sponge sleeve performs final fine cleaning and absorbs residual liquid, ensuring the thoroughness and reliability of the cleaning effect. 2. The cleaning block uses a steel tube with a built-in sponge sleeve, which can avoid direct hard contact between the bare wire and the metal hole. In addition, the angle of the bend end is perpendicular to the bare wire, ensuring that the wire is directly facing and passes through the center of the sponge sleeve after coming out of the guide wheel, instead of being scratched by the edge of the metal tube opening, which can specifically solve the risk of scratching. 3. The lower and upper sponge wiping plates of the bare wire wiping assembly are fixed with nuts. The sponge sleeve of the bare wire cleaning block is also plug-in type, which allows operators to quickly replace consumables within minutes without special tools, greatly improving the maintainability and operational efficiency of the equipment. In addition, the stable support of the first and second wire guide rollers ensures the stability of the bare wire in the wiping assembly. The setting of the first and second wire guide rollers ensures that the immersion path and exit angle of the bare wire in the cleaning solution are reasonable, which together maintains the stability of the operating tension and makes the process smoother and more reliable.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0014] Example A device for cleaning bare enameled wires, such as Figure 1-6 As shown, it includes a cleaning tray 1, a wire guiding mechanism 2 mounted on the cleaning tray 1, and a bare wire 3 passing through the wire guiding mechanism 2 into the cleaning tray 1.

[0015] The wire guiding mechanism 2 includes a support frame 21 fixed to the cleaning tray 1 by screws, and wire guide frames 22, which are fixed to the support frame 21 by bolts and are arranged at equal intervals. The wire guiding mechanism 2 adopts the design of equally spaced wire guide frames 22, which allows each wire guide frame to independently guide and clean one bare wire 3, enabling multiple bare wires 3 to be processed in parallel with consistent paths, uniform cleaning effect, and a very compact structure, saving space and improving overall production efficiency.

[0016] The wire guide frame 22 includes a crossbar 221 fixed to the support frame 21 by bolts, a first wire guide rod 222 fixedly installed below one end of the crossbar 221 and extending into the cleaning tray 1, a first wire guide wheel 223 and a second wire guide wheel 224 fixedly installed below the crossbar 221, a bare wire wiping assembly 225 fixedly installed below the crossbar 221 and located between the first wire guide wheel 223 and the second wire guide wheel 224, a second wire guide rod 226 fixedly installed below the other end of the crossbar 221 and extending into the cleaning tray 1, and a bare wire cleaning block 227 fixedly installed at the middle of the outer side of the second wire guide rod 226 by bolts.

[0017] The two ends of the crossbar 221 are bent downwards and have wire wheel mounting ears 2211. The wire inlet wheel 2212 is installed on the wire wheel mounting ear at one end of the crossbar 221 and is used to clean the wire inlet with the first wire guide rod 222. The wire outlet wheel 2213 is installed on the wire wheel mounting ear at the other end of the crossbar 221 and is used to guide the wire outlet with the second wire guide rod 226.

[0018] The lower end of the first lead rod 222 is equipped with a first lead rod guide wheel 2221.

[0019] The bare wire wiping assembly 225 includes a mounting plate 2251, an upper through-mount stud 2252 welded above the mounting plate 2251 and fixed by a nut after passing through the crossbar 221, a lower through-mount stud 2253 welded below the mounting plate 2251, a lower sponge wiping plate 2254 fixed by a nut on the lower through-mount stud 2253, and an upper sponge wiping plate 2255 fixed by a nut on the lower through-mount stud 2253 and cooperating with the lower sponge wiping plate 2254. Specifically, the lower sponge wiping plate 2254 and the upper sponge wiping plate 2255 are arranged opposite to each other. When the bare wire 3 passes through, it can perform a comprehensive and powerful squeezing wiping of the upper, lower and side surfaces of the bare wire 3, effectively removing most of the oil and impurities.

[0020] The lower end of the second lead rod 226 is equipped with a second lead rod guide wheel 2261.

[0021] It should be further explained that the stable support of the first wire guide roller 223 and the second wire guide roller 224 ensures that the bare wire is in a stable position in the wiping assembly, without jumping or shifting, making the wiping process uniform and effective. The setting of the first wire guide roller 2221 and the second wire guide roller 2261 reasonably guides the immersion path of the bare wire in the cleaning tray and helps to maintain the tension stability of the bare wire during operation, preventing the cleaning effect from being affected or the wire from breaking due to loosening or being too tight.

[0022] The bare wire cleaning block 227 includes a cleaning block body 2271 fixed to the second lead rod 226 by bolts, a bent end 2272 integrally formed with the cleaning block body 2271 and having a round hole, a steel tube 2273 embedded in the round hole of the bent end 2272, and a sponge sleeve 2274 inserted inside the steel tube 2273. Specifically, the steel tube 2273 has threads at both ends, and after the steel tube 2273 passes through the round hole of the bent end 2272, nuts are screwed onto both ends to securely install the steel tube 2273 onto the bent end 2272. Moreover, as the final fine cleaning step, the bare wire cleaning block 227's internal sponge sleeve can further absorb residual trace dirt and cleaning fluid, ensuring that the cleanliness of the bare wire reaches an extremely high standard before exiting the wire, thus improving the cleaning quality and reliability.

[0023] It should be further explained that the inclination angle of the bent end 2272 is based on the inclination angle of the bare wire 3 from the second lead rod guide wheel 2261 to the lead wheel 2213. The bent end 2272 needs to be perpendicular to the bare wire 3 so that the bare wire 3 can always pass through the sponge sleeve 2274 without being scratched by the steel pipe 2273.

[0024] During the cleaning process, the first end of the bare wire 3 first enters from the upper end of the infeed wheel 2212, turns downward and passes through the lower end of the first lead rod guide wheel 2221, turns upward after passing through the first lead rod guide wheel 2221 and passes through the first wire guide wheel 223, the bare wire wiping component 225 and the second wire guide wheel 224 in sequence. The bare wire 3 is stably supported by the first wire guide wheel 223 and the second wire guide wheel 224. The surface is wiped by the bare wire wiping component 225. Then, it turns downward after passing through the second wire guide wheel 224 and enters the lower end of the second lead rod guide wheel 2261. Then, it turns upward after passing through the first lead rod guide wheel 2221 and passes through the sponge sleeve 2274 on the bare wire cleaning block 227. Finally, it enters the outlet wheel 2213 and is guided out from the upper end of the outlet wheel 2213.

[0025] Meanwhile, the lower sponge wiping plate 2254 of the bare wire wiping assembly 225 is fixed to the upper sponge wiping plate 2255 by nuts, and the sponge sleeve 2274 of the bare wire cleaning block 227 is also plug-in type, which makes it convenient for operators to quickly replace consumables within minutes without special tools, greatly improving the maintainability and operating efficiency of the equipment.

[0026] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
