The present invention provides a synchronous wire winding device with tensioning function, which relates to the field of transmission control, including a synchronous wire winding transmission device and a spring
pulley tensioning device. The synchronous wire winding transmission device includes: a motor, a motor bracket, a lead screw, a drum, a synchronous slide rail, a gear pair, a motor, a
coupling, a bearing seat, a bearing, an upper aluminum plate, and a lower aluminum plate; the spring
pulley tensioning device includes: a spring and a
pulley bracket. It is characterized in that: during the use of the device, the motor drives the
rope to realize synchronous non-overlapping winding on the drum, and at the same time, the spring pulley tensioning device can ensure that the
rope is always in a tensioned state during the winding process, so as to prevent the
rope from detaching from the pulley.
