The invention provides an emptying device on power wire manufacturing equipment and belongs to the electric wire cable technology field. By using the device, technical problems that a lead enters into in a linear mode, power wire quality is poor, and so on are solved. The emptying device on the power wire manufacturing equipment comprises a pedestal 1 and an annular support 1. The support 1 is fixedly arranged on the pedestal 1. The support 1 is fixedly provided with a driving motor, a main shaft, a main gear 1 and three slave gears 1. The driving motor is connected to the main shaft through a belt. The main gear 1 is fixedly arranged on the main shaft. The three slave gears 1 are simultaneously engaged with the main gear 1. The slave gears 1 are rotatably connected to the support 1. Each slave gear 1 is provided with an individual emptying roller. The slave gears 1 realize rotation through tubular short shafts 1. Three leads of the power wire pass through internal portions of the three short shafts 1. Under rotation of the short shafts 1, the three leads are forced to synchronously rotate with the corresponding short shafts 1. In the invention, advantages that power wire quality and performance can be increased and so on are possessed.
