Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a multi-line photovoltaic welding ribbon parallel type automatic wire drawing machine. Background Art

[0002] Solar panels are connected using photovoltaic ribbons. Copper wire undergoes processes such as splitting, coating, and washing to form the final photovoltaic ribbon. Application number 201620274893.3 describes a wire drawing mechanism for an integrated photovoltaic ribbon welding machine and a photovoltaic ribbon welding machine. This solves the current problem of inconsistent copper wire thickness during operation, which often leads to wire breakage and poorly regulated copper wire tension during the drawing process, thus preventing optimal performance in subsequent copper wire processing. The key technical solution is an adjustable fixed pulley assembly comprising an upper fixed pulley mounted on a vertical rod and an adjustment mechanism. The adjustment mechanism includes a connecting rod, one end of which is connected to an adjustable fixed pulley and a counterweight that can be moved toward or away from the adjustable fixed pulley. A cleaning cylinder for the copper wire is located on one side of the vertical rod along the direction of copper wire transport. This equipment suffers from insufficient wire drawing tension and an inability to adjust the tension, resulting in the processed copper wire not being suitable for photovoltaic ribbon processing.
