Nowadays, most of the doors of storefronts use fast rolling shutter doors. The reason why fast rolling shutter doors are so popular is not only because of its convenient operation and high efficiency, but also many additional advantages.
Top structure:
The transmission mechanism of the fast rolling shutter door is installed in the top chassis of the door. The chassis is made of 2mm thick galvanized steel plate. Both ends are made of 6mm thick steel plate. The end plates are equipped with reel bearings, drive motors, and balance systems. The mounting seat and mounting hole of the component, and the surface of the steel plate are sprayed into the color required by the customer. The reel is installed in the chassis and consists of a reel, a shaft end, a bearing seat, etc. The size of the reel is calculated according to the height and width of the door opening, and a reasonable size is selected.

There are sealing tops fixed on both sides of the guide groove of the guide trough box to ensure certain sealing requirements. At the bottom of the guide trough box about 1m above the ground, the installation position of the infrared monitor is reserved.
Cord: high-quality PVC cord is selected for the quick door, with a thickness of 1.2mm, which has the advantages of high strength, impact resistance, and not easy to puncture. You can also choose transparent PVC material to make curtain cloth or partially use transparent PVC material to make curtain cloth, so as to observe the situation on both sides of the soft curtain door.

Driving device: directly drive the rotating shaft of the soft curtain door through the deceleration motor, and select the reducer with different speed ratios according to the requirements of the lifting speed to achieve the required lifting speed, and the fastest speed can reach more than 80cm/s. The control circuit adopts frequency conversion control, so that the curtain fabric can start slowly and stop slowly when running, and can make the curtain fabric stop automatically when it is in place, and stop the movement during the running process.
Control box: There is a control box for the quick rolling shutter door, which can be used to control "open", "stop" and "close" and set control buttons on the other side of the control box to operate "open", "stop" and "close".
