The invention provides a winding machine, which comprises a frame, as well as a first winding unit and a second winding unit for winding a lead strip, and a changeover mechanism for controlling the lead strip to enter the first winding unit or the second winding and arranged on the frame; when the winding machine is used, the lead strip, guided by the changeover mechanism, enters the first winding unit and is wound; when the lead strip in the first winding unit is wound to a set volume, the lead strip is cut off by the changeover mechanism, and guided by the changeover mechanism, enters the second winding unit and is wound; when the lead strip in the second winding unit is wound to a set volume, the lead strip, under the action of the changeover mechanism, enters the first winding unit again and is wound; and the process is repeated in such a way, and the lead strip is wound continuously. The winding machine has the beneficial effects that through arranging the two winding units on the winding machine, when the machine works, the two winding units can be used alternately to wind the lead strip, so that the winding of the lead strip has no stop, thus the machine is especially applicable to continuous lead strip producing equipment.
