The principle of automatic take-up machine
May 09, 2018

Automatic take-up machine is the use of multiple take-up winch, up to plus four concentric contacts, the surface of the scroll spring storage, energy release and one-way lock ratchet lock line.

When the power cable is pulled out, the scroll spring retains energy, and when the cable is pulled out, the rotary shaft rotates under the action of the spiral spring until it is locked by the ratchet, and the power line stops. When the line is closed, a button or other pipe is used to open the lock. The energy storage of the scroll spring is released, and the rotating shaft is driven to wind up and retract the power cable.
