Top structure: The transmission and organization equipment of the fast rolling shutter door is located in the top chassis of the door opening. The chassis is made of 2mm thick galvanized steel plate, and the two ends are made of 6mm thick steel plate. On the end plate, there are equipment roller bearings, driving motors, equipment seats and equipment holes for balancing system components. The surface of the steel plate is sprayed with plastic to meet the customer's requirements. The rolling equipment is located inside the chassis and consists of a drum, shaft end, bearing seat, etc.
Guide box: The guide box is made of 2mm thick galvanized steel plate, standing on both sides of the door opening and fixed to the wall. The chassis is placed on the top of the guide box and fixed to the guide box and wall with bolts. Sealing strips are fixed on both sides of the guide groove of the guide groove box to ensure sealing requirements. At the bottom of the guide groove box about 1 meter above the ground, a device position with an infrared monitor is reserved. The guide groove box is treated with spray molding and has the same color as the chassis. The bristles inside the guide groove are pressed against the curtain fabric to control that it will not detach from the guide groove. If the car collides with the door, the door curtain will detach from the guide groove to prevent damage to the door body.
Cord fabric: The cord fabric is manufactured in sections, with each section having a height of approximately 700 millimeters. Each section of the cord fabric is connected into a whole through a specially made aluminum wind resistant strip, with a thickness of 1.2 millimeters. The cord fabric has the advantages of high strength, impact resistance, and resistance to puncture. Optional δ= 2mm transparent PVC is used to manufacture the curtain fabric for observing the condition on both sides of the soft curtain door. An aluminum bottom beam is installed at the bottom of the curtain fabric to prevent impact. The top of the soft bag curtain fabric is fixed to the drum through screws and pressure strips.
Drive equipment: The soft curtain door shaft is directly driven by a deceleration motor, and the speed is controlled according to different actual needs, adjusted to the required speed, with the fastest speed reaching over 80cm/s. The control circuit adopts variable frequency control to achieve slow start and slow stop during the operation of the cord fabric, and can make the cord fabric stop automatically in place, which can stop the movement during the operation process.
Control: The soft curtain door is equipped with a control box, which can be operated to "open", "stop", and "close". A control button can be set on the other side of the control box for "open", "stop", and "close" operations. Remote control operation and radar exploration or geomagnetic induction automatic door opening and closing can be selected according to needs. Infrared monitoring devices are installed on both sides of the door opening. When obstacles pass through the door opening during the movement of the door body, the curtain movement will stop or return to the door opening status.
