1. Top structure
The transmission mechanism of the fast Roller shutter is installed in the box at the top of the door opening. The box is made of 2mm thick galvanized steel plate. Both ends of the box are made of 6mm thick steel plate. The end plate is equipped with mounting seats and mounting holes for installing reel bearings, driving motors, and balancing system components. The surface of the steel plate is sprayed with plastic to become the color required by customers. The reel is installed inside the chassis and consists of a drum, shaft end, bearing seat, etc. The size of the drum is calculated based on the height and width of the door opening, and a reasonable size is selected. On this door, the diameter of the drum is 219mm.
2. 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. There are sealing strips fixed on both sides of the guide groove of the guide groove box to ensure certain sealing requirements. At the bottom of the guide groove box about 1m above the ground, there is a reserved installation position for the infrared monitor. The guide slot box of the fast Roller shutter is sprayed with plastic and is the same color as the box. The brush in the guide slot is against the cord fabric to limit the cord fabric from leaving the guide slot. In this way, when the car hits the door, the curtain will leave the guide slot, so as to avoid damage to the fast Roller shutter body.
3. Cord fabric
The cord fabric of the fast Roller shutter can be made in sections, each section of which is about 700mm high. Each section of cord fabric is connected into a whole cord fabric through a specially made aluminum wind resistant strip, which has the advantages of high strength, impact resistance, and puncture resistance. In addition, we can also use transparent PVC material to make the curtain or partially use transparent PVC material to make the curtain, in order to observe the situation on both sides of the soft curtain door. There is an aluminum bottom beam at the bottom of the curtain, and the top of the anti-collision soft bag curtain is fixed to the drum through screws and pressure strips.
4. Drive device
The shaft of the soft shutter is directly driven by the deceleration motor. According to the requirements of the lifting speed of the fast Roller shutter, different speed ratio reducers are selected to achieve the required lifting speed, which can reach more than 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 automatically stop the cord fabric in place and stop its movement during operation.
5. Control system
The fast Roller shutter is equipped with a control box, which can operate "open", "stop" and "close", and a control button can be set on the other side of the wall of the control box to operate "open", "stop" and "close". The quick Roller shutter can be equipped with remote control operation, radar detection or geomagnetic induction automatic door opening and closing as required. The infrared monitoring device is set on both sides of the door opening. When an obstacle passes through the door opening when the door body is moving, the movement of the curtain will stop or return to the open state.
