Description

Technical Field

[0001] This utility model relates to the field of wire and cable manufacturing technology, and in particular to a device for uniformly coating enameled wires. Background Technology

[0002] Enameled wire, also known as winding wire, is an electromagnetic wire consisting of one or more layers of enamel material with excellent insulating properties uniformly coated on the outside of a conductive core (usually copper or aluminum). This special structure not only retains the good conductivity of the metal conductor, but also effectively isolates the current between adjacent turns through the insulating enamel layer, preventing short circuits and leakage. Enameled wire is widely used in various electrical equipment that need to achieve electromagnetic conversion or electromagnetic induction functions.

[0003] The quality of enameled wire is closely related to the uniformity of the coating. However, in traditional horizontal coating devices, after the conductive core passes through the coating mold, the varnish is affected by gravity and flows downward along the surface of the core, causing local accumulation of insulating varnish at the bottom of the conductor. This uneven distribution of the varnish film may cause safety hazards such as unstable electrical insulation performance and short circuits between winding turns, thus seriously affecting the overall performance and reliability of the product.

[0004] Therefore, it is necessary to design a device for uniformly coating enameled wire to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the drawback of uneven paint distribution due to gravity, the technical problem to be solved is to provide a device for uniformly coating enameled wires.

[0006] The technical solution is as follows: A device for uniformly coating enameled wire includes a storage tank, rotating shafts, guide wheels, support plates, first coating components, guide blocks, fixing blocks, second coating components, third coating components, transport pipes, diaphragm pumps, four-way pipes, spray nozzles, and controllers. Two rotating shafts are fixedly connected to both sides of the storage tank, and multiple guide wheels are rotatably connected to each shaft. Support plates are fixedly connected to both sides of the storage tank. Multiple first coating components are fixedly connected to the right support plate. A guide block is fixedly connected to the top of the storage tank, positioned above the first coating components. A fixing block is fixedly connected to the upper part, and multiple second painting parts are fixedly connected to the fixing block. Multiple third painting parts are fixedly connected to the support plate on the left side. A transport pipe is fixedly connected to the middle of the storage tank. A diaphragm pump is connected to and connected to the transport pipe. A four-way pipe is connected to and connected to the top of the transport pipe. Another transport pipe is connected to and connected to both sides of the four-way pipe. A fourth transport pipe is connected to and connected to the front of the four-way pipe. Multiple paint spray nozzles are connected to and connected to the bottom of the three transport pipes located at the top. A controller is fixedly connected to the storage tank. The controller is electrically connected to the diaphragm pump.

[0007] Preferably, the system also includes a heating ring and a sensor. The heating ring and the sensor are fixedly connected to the lower part of the liquid storage tank, and both the heating ring and the sensor are electrically connected to the controller.

[0008] Preferably, the container also includes a sealing cap, a sealing ring, glass plates, an exhaust fan, and a connecting block. The sealing cap is rotatably connected to the top of the liquid storage tank, and a sealing ring is fixedly connected to the bottom of the sealing cap. The sealing ring abuts against the top of the liquid storage tank. Multiple glass plates are fixedly connected to the sealing cap, and exhaust fans are fixedly connected to both sides of the sealing cap. Connecting blocks are connected and communicate between both sides of the sealing cap.

[0009] Preferably, the tank also includes gas springs, with gas springs rotatably connected to both sides of the liquid storage tank, and the piston rod of each gas spring is rotatably connected to the sealing cap.

[0010] Preferably, a support frame is also included, with the bottom of the liquid storage tank being fixedly connected to the support frame.

[0011] Preferably, a handle is fixedly provided on the sealing cap.

[0012] The beneficial effects of this utility model are as follows: 1. Through the structural cooperation between the guide wheel and the first, second and third coating parts, the conductive wire core passes through the coating parts set in different directions in sequence during the coating process, thereby achieving uniform coating from multiple angles and directions. This not only effectively reduces the uneven distribution of paint caused by gravity, but also significantly improves the coverage and adhesion quality of the paint film, thereby improving the overall insulation performance and product consistency of the enameled wire.

[0013] 2. This utility model achieves paint recovery and recycling through the inclined structure at the bottom of the liquid storage tank and the setting of the transport pipe, reducing waste, improving resource utilization, and reducing the risk of environmental pollution.

[0014] 3. This utility model effectively prevents harmful gases generated during heating from spreading outward through the sealing fit between the sealing cover and the sealing ring. At the same time, through the connection of the connecting block and the exhaust gas treatment pipe, and the control of the controller to operate the exhaust fan, harmful gases are extracted and centrally treated in a timely manner, preventing them from overflowing from other openings of the liquid storage tank, thus further improving the safety and environmental performance of the equipment.

Detailed Implementation

[0020] Example: A device for uniformly coating enameled wire, such as... Figures 1-4 As shown, the system includes a storage tank 1, rotating shafts 2, guide wheels 3, support plates 4, first painted components 5, guide blocks 6, fixing blocks 7, second painted components 8, third painted components 9, transport pipes 10, diaphragm pumps 11, four-way pipes 12, spray nozzles 13, and controllers 14. The storage tank 1 has two rotating shafts 2 symmetrically connected by bolts on its left and right sides. Each rotating shaft 2 has five guide wheels 3 arranged in a linear array and rotated. Support plates 4 are symmetrically welded to the left and right sides of the storage tank 1. Five first painted components 5 are arranged in a linear array on the right support plate 4 and connected by bolts. A guide block 6 is bolted to the upper right side of the storage tank 1, located directly above the first painted components 5. Five through holes on the guide block 6 correspond one-to-one with the first painted components 5 directly below it. A fixing block 7 is welded to the middle of the upper part of the storage tank 1, and five second painted components 8 are bolted to the fixing block 7. Five third painted components 8 are bolted to the support plate 4 on the left side. A transport pipe 10 is fixedly connected to the middle rear side of the paint part 9 and the liquid storage tank 1. The middle of the transport pipe 10 is connected to and connected to a diaphragm pump 11. The diaphragm pump 11 is connected to the liquid storage tank 1 by bolts. The top of the transport pipe 10 is connected to and connected to a four-way pipe 12. The left and right sides of the four-way pipe 12 are connected to and connected to another transport pipe 10. Both transport pipes 10 are fixedly connected to the liquid storage tank 1. Both transport pipes 10 are L-shaped, and the lower part of the longitudinal section is connected to and connected to five paint spray heads 13. Each paint spray head 13 of the liquid storage tank 1 is located above the corresponding first paint part 5 or third paint part 9. The front side of the four-way pipe 12 is connected to and connected to a fourth transport pipe 10. The lower end of the fourth transport pipe 10 is connected to and connected to five paint spray heads 13. Each paint spray head 13 of the liquid storage tank 1 is located above the corresponding second paint part 8. The right front side is connected to a controller 14 by bolts. The controller 14 is electrically connected to the diaphragm pump 11.

[0021] like Figure 1As shown, it also includes a heating ring 15 and a sensor 16. The heating ring 15 is bolted to the lower rear side of the liquid storage tank 1. The heating ring 15 is adjacent to the transport pipe 10 located at the bottom. The sensor 16 is bolted to the right rear side of the liquid storage tank 1. Both the heating ring 15 and the sensor 16 are electrically connected to the controller 14.

[0022] This device can be used when coating conductive wire cores. First, the pre-treated conductive wire core is inserted into the device. The conductive wire core will pass around the guide wheel 3, through the first coating component 5, the guide block 6, the second coating component 8, and the third coating component 9. After placing the conductive wire core, the paint is poured into the storage tank 1. The operator starts the diaphragm pump 11 and the heating ring 15 through the controller 14. The heating ring 15 heats the paint, enhancing its fluidity and making it easier to adhere to the surface of the conductive wire core. The sensor 16 feeds back the temperature of the paint to the controller 14 in real time. The 14th step adjusts the working state of the heating ring 15 according to the received data, thereby precisely controlling the temperature of the paint liquid to avoid it being too high or too low, ensuring the stability of the painting process and the quality of the paint film. The diaphragm pump 11 transports the paint liquid from the lower transport pipe 10 to the upper part, and it flows out from the spray nozzle 13 through the transport pipe 10, and then drips into the first painting part 5, the second painting part 8, and the third painting part 9. The conductive wire core moves vertically upward by the guide wheel 3. The conductive wire core passing through the first painting part 5 will be contaminated with paint liquid. After passing through the guide block 6, the excess paint liquid is scraped off and adheres to the conductive wire core. The enamel coating on the wire core is evenly distributed on the surface under tension, completing the first coat. Then, guided by guide wheel 3, it moves horizontally to the left, picking up enamel as it passes the second coating element 8. The finest part of the cross-section of the second coating element 8 then scrapes off excess enamel, completing the second coat. Next, guided by guide wheel 3, the conductive wire core moves vertically downwards, picking up enamel as it passes the third coating element 9. The finest part of the cross-section of the third coating element 9 then scrapes off excess enamel, completing the third coat. Finally, after three coats, the conductive wire core passes the guide wheel... The guide for part 3 moves horizontally to the left and enters the curing process. During the three coating processes on the conductive wire core, two of them are applied vertically, which helps to reduce the influence of gravity on the distribution of the paint, thereby improving the uniformity and quality of the coating. The paint flowing down from the holes below the first coating part 5 and the third coating part 9, as well as the paint overflowing from the second coating part 8, will all flow into the storage tank 1. The bottom of the storage tank 1 is provided with a sloping structure, which can guide the paint to flow to one side of the transport pipe 10 and concentrate it at the bottom of the transport pipe 10 for easy subsequent recycling.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a sealing cover 17, a sealing ring 18, a glass plate 19, an exhaust fan 20, and a connecting block 21. The sealing cover 17 is rotatably connected to the top rear side of the liquid storage tank 1. A handle is fixedly provided in the middle of the front side of the sealing cover 17. The sealing ring 18 is glued to the bottom of the sealing cover 17 and abuts against the top of the liquid storage tank 1. Three glass plates 19 are glued to the sealing cover 17. The three glass plates 19 are located directly above the first painted part 5, the second painted part 8, and the third painted part 9, respectively. The exhaust fan 20 is symmetrically connected to the left and right sides of the rear of the sealing cover 17 by bolts. The connecting block 21 is symmetrically connected and communicated to the left and right sides of the top of the sealing cover 17.

[0024] like Figure 4 As shown, it also includes gas springs 22. Gas springs 22 are symmetrically and rotatably connected to the rear of the liquid storage tank 1. The piston rod of each gas spring 22 is rotatably connected to the sealing cover 17.

[0025] like Figure 1 As shown, it also includes a support frame 23, which is symmetrically welded to the bottom of the liquid storage tank 1.

[0026] When the paint is heated, harmful gases are generated that could endanger the health of the operators. The sealing cover 17 and sealing ring 18 can prevent the harmful gases from overflowing on a large scale. The connecting block 21 will be connected to the exhaust gas treatment pipe. The operator can turn on the exhaust fan 20 through the controller 14 to suck out the harmful gases and prevent them from overflowing from other openings on the liquid storage tank 1. The glass plate 19 on the sealing cover 17 allows the operator to observe the working status of the device and the painting process. When it is necessary to add paint or to repair the device, the operator can hold the handle and lift the sealing cover 17 clockwise. The gas spring 22 can facilitate the lifting and closing of the sealing cover 17 and keep the sealing cover 17 in the open position. The support frame 23 can lift the device body off the ground to prevent it from getting damp.
