AI Technical Summary
⚠Technical Problem
In the existing electromagnetic wire coating process, the use of an upper and lower nozzle structure results in uneven thickness on both sides and in the upper and lower areas of the wire.
⚗Method used
The coating method combines a one-way valve nozzle and an annular nozzle. The paint is sprayed out through an annular spray screen, and the spherical groove built into the nozzle and the shaft cover form a rotating mechanism to achieve uniform coating of the paint mist on the circumference of the cable.
🎯Benefits of technology
It achieves uniform coating on the surface of electromagnetic wires, eliminates thickness differences caused by traditional spraying methods, and improves spraying quality.

Abstract
This utility model discloses an automatic uniform coating device for electromagnetic wire insulating varnish, belonging to the field of electromagnetic wire spraying technology. The automatic uniform coating device for electromagnetic wire insulating varnish includes a coating processing box with a dust cover on top. A cable routing groove is located at one end of the coating processing box, where a cable body is housed. Multiple spray nozzle shafts are arranged on the inner side of the cable routing groove. To address the problem that existing electromagnetic wire coating methods often use an upper and lower nozzle structure, which still results in uneven thickness on both sides and the top and bottom of the cable, this device uses a one-way valve nozzle to enter the spray chamber. After the valve controls the flow rate, the varnish is sprayed out as a ring-shaped spray curtain by an annular nozzle. The spherical groove inside the nozzle and the shaft cover form a rotating mechanism, achieving self-rotation spraying under the pressure of the varnish, ensuring that the varnish mist evenly coats the circumference of the cable.
