The storage box 501 is used for placing high-temperature-resistant paint, and the drying box 502 is used for drying a paint layer on a wire rod.
Specifically, the storage box 501 and the drying box 502 have an inlet 503 and an outlet 504 respectively formed on two sides thereof for the wires to pass in and out, guide wheels 505 are rotatably mounted in the inlet 503 and the outlet 504 to assist in wire transmission and prevent the wires from shifting, and paint scraping members 506 are mounted in the outlet 504 to scrape off redundant paint. In addition, the bottom of the storage tank 501 is also provided with a guide wheel 505.
The painting member 506 includes: a conical head 507 and a scraping ring 508 connected with the end part of the conical head 507; wherein, the conical head 507 is provided with a hollow structure. The lower end of conical head 507 communicates with outlet 504, does benefit to the lacquer backward flow after scraping to storage case 501.
The inside of stoving case 502 is installed and is installed electric heating pipe 509, is connected with the temperature controller on the electric heating pipe 509, and the top intercommunication of stoving case 502 has exhaust pipe 510, and the last intercommunication of exhaust pipe 510 has exhaust fan 511.
Specifically, after the wire rod coats the lacquer layer in storage case 501, can spread in scraping ring 508, scrape ring 508 and can scrape unnecessary lacquer on the wire rod and flow back to storage case 501 in, the wire rod after the coating is dried to the lacquer layer by electric heating pipe 509 in the inside of stoving case 502, and exhaust fan 511 discharges steam through exhaust pipe 510, has made things convenient for the coating on high temperature resistant lacquer layer.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
