The fast rolling door is an automated control equipment consisting of a door frame and curtain drive motor control system. Lifting speed: ./-./ From bottom to top, it usually takes about seconds (the speed is twice that of electric rolling shutters). Vehicles and pedestrians do not need to wait and do not constitute an obstacle. There are many ways to trigger signals for opening the door: manual button, radar induction, infrared photoelectric induction, geomagnetic induction, remote control, etc.
Door cloth material: Generally, curtain cloth is very suitable for fast rolling doors. The origin is preferably German or French. thickness.-.. Colors include orange, yellow, blue, silver, transparent mesh, etc. Orange is the first choice because orange is very eye-catching, has a warning effect, and has a certain insect-proof function.
Drive motor: The fast rolling door uses a brake reduction motor, which requires fast braking and low noise. Generally, the brake motors sold on the market either have poor braking effect or make loud braking noise, so they are not suitable for use in fast rolling doors. Speed ratio: more appropriate. Working process: The door-opening sensor provides a trigger signal to the control system. The control system issues instructions to the frequency converter to start the drive motor according to the current position of the fast rolling door, causing the door curtain to rise quickly. When vehicles and pedestrians pass through, the door curtain automatically lowers and closes the passage until the next door-opening signal opens again. As the name suggests, the fast rolling door lifts and lowers very quickly and cannot be started and stopped directly like the steel rolling door. Generally, a frequency converter is required to control the speed of the motor. When rising, the faster the better. When reaching the position (left and right), there needs to be a deceleration and buffering stop process to prevent hitting the track, preventing people from being pinched, and reducing noise. This is also a criterion for measuring the performance of fast rolling doors.
There are two ways to position fast rolling shutters:
Mechanical positioning: This positioning method has the same advantages as steel rolling shutters in that it is fast and has low requirements on the controller.
Rotary encoder positioning: The elevators we often take are all positioned using rotary encoders. The advantage of this method is that the positioning is accurate. Taking an encoder with a resolution of The accuracy can be achieved. The height setting is simple. The fast rolling door control system designed by the Universal Door Industry has only one button to set the height arbitrarily. This is very practical. If it is only for passing people, setting the height to 1 meter is enough to avoid futile openings, such as forklifts, etc. When tall objects pass by, just reset the height. The disadvantage is that the rotary encoder itself is relatively expensive, is a delicate component, and needs to be used in conjunction with the program, so the cost of the control system is relatively high.
