Forward and reverse winding device

The utility model relates to a forward and reverse winding device which comprises a machine frame, a torque motor installed at the lower end of the machine frame, a driving chain wheel installed on the torque motor, a supporting shaft 7 installed at the upper end of the machine frame and a supporting shaft seat 12 of a reverse supporting shaft 11, a forward gear installed on a forward supporting shaft, and a driven chain wheel integrated with the forward gear. And a reverse gear is mounted on the reverse supporting shaft. The device is provided with two groups of connected air expansion shaft seats, a pair of gear transmission pairs is arranged below the air expansion shaft seats, and the pair of gear transmission pairs are respectively meshed with air expansion shaft gears supported on the air expansion shaft seats, so that the rotation directions of air expansion shafts on different air expansion shaft seats are opposite, and the problem of frequent reversing of a motor during winding is solved.
