Description

Technical Field

[0001] The utility model relates to the field of metal conductor coating equipment, in particular to an automatic coating machine for paper-covered wires. Background Art

[0002] Paper covered wire is a kind of wire that uses insulating paper as the main insulating material. Through a specific process, the paper is tightly and continuously wrapped around the outer layer of the metal conductor to form the insulation layer of the wire and cable. This process is usually completed by a professional automatic covering machine to ensure the uniformity, tightness and reliability of the covering. Paper covered wire is widely used in the electrical industry, especially in power cables, motor windings, transformer coils and other occasions that require high temperature resistance and high insulation performance.

[0003] The existing coating machine is basically composed of two guide wheels, two extrusion wheels, a collecting roll and a motor. A metal conductor is arranged between the two layers of insulating paper. The two layers of insulating paper are fitted to the metal conductor through the two guide wheels. Then, the two layers of insulating paper are coated on the metal conductor through two sets of extrusion forces. Finally, the motor drives the collecting roll to reel up the coated paper-wrapped wire. The two existing guide wheels are basically fixed on the equipment by bolts. When the staff needs to produce other types of cardboard wires, due to the different diameters produced, the staff needs to use tools to remove the bolts before the staff can adjust the spacing between the two guide wheels. After the adjustment is completed, the staff uses the tools to tighten the bolts again to complete the fixation of the two guide wheels. The existing guide wheel spacing adjustment process is relatively cumbersome, which increases the labor intensity of the staff to a certain extent.

[0004] Therefore, it is necessary to provide a new paper-covered wire automatic covering machine to solve the above-mentioned technical problems. Utility Model Content

At the same time, the connecting assembly enters another circular groove at the other end of the frame to complete the adjustment of the spacing between the guide mechanisms. This structure simplifies the adjustment process of the spacing between the guide mechanisms and reduces the labor intensity of the staff to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS
