[0002] Wire pipes are important supporting facilities for conveying water, electricity, gas, heating and oil. In modern urban construction, for the purpose of aesthetics or safety, the above-mentioned wire pipes are often buried deep underground. However, in the actual laying of wire pipes, the laid wire pipes are often broken and scrapped due to improper protection. Therefore, in order to extend the service life of the wire pipes and improve the strength of the wire pipes, a wrapping machine is generally used to wrap various protective wires around the outer circumference of the wire pipes.
