technical field

The invention relates to a braking device suitable for an electric rolling door machine.

Background technique

The rolling shutter door is a door that rotates up and down around the scroll above the door in a fixed slideway by connecting the multi-joint movable door pieces in series. The electric rolling door machine drives the reel of the rolling door through the motor to realize the automatic opening and closing of the rolling door. In addition to being driven by a motor, the electric rolling door machine can also be rotated and driven manually through a sprocket. Since both the manual drive and the motor drive are transmitted through the reel, a mechanical structure capable of switching between the two is required. When the electric rolling shutter door machine is not working, the hand pull sprocket and the brake friction plate are attached to each other under the action of the spring to prevent the reel from rotating; when the switch that controls the upward or downward movement of the door curtain is pressed, the iron core component is energized to attract the hand pull chain The wheel is separated from the brake friction plate, and the reel rotates to drive the door curtain to go up or down. When the stop switch that controls the door curtain is pressed, the iron core component is powered off and separated from the hand chain wheel. The hand chain wheel is connected to the brake friction plate under the action of the spring. They fit together to prevent the reel from rotating, and the door curtain stops; when the power is off, the positioning platen can be pulled by the hand chain, which drives the hand chain wheel to rotate, which in turn drives the reel to rotate, and drives the door curtain to slide up and down; so the mechanical structure of this switch is usually called The brake device of the electric rolling door machine.
