AI Technical Summary
In the prior art, the translational transmission belt is prone to slippage when driven to rotate by the translational transmission roller, which causes the magnetic levitation translational automatic door to be unable to move smoothly.
The system employs a reversible motor-driven steel wire rope winding wheel system. Two reversible motors control the rotation of the winding wheel, enabling the winding and unwinding of the steel wire rope and driving the opening and closing of the connecting plate and the door, thus preventing the transmission belt from slipping.
It achieves stable opening and closing of the sliding automatic door, avoids belt slippage, and improves the door's moving reliability and automation level.
