Working principle of rolling shutter door

The rolling shutter door is connected in series by multi-joint movable door pieces, the electric rolling shutter door is connected in series by multi-joint movable door pieces, and the upper and lower doors rotate around the scroll above the door with fixed slideways. Suitable for commercial facades, garages, shopping malls, hospitals, factories and mines and other public places or houses. Especially in the place where the door opening is large and it is not convenient to install the ground door body, it plays a convenient and quick opening role. Such as garage doors, shopping mall fire shutter doors, airplane garage doors, etc.

Form starting from:

1. Manual shutter. With the help of the torsion spring on the axis of the roller shutter, the roller shutter switch can be manually pulled up and down.

2. Electric roller blinds. A special motor is used to drive the central shaft of the roller blind to rotate, so as to realize the roller blind switch, which will automatically stop when the rotation reaches the upper and lower limit set by the motor.

The special motors for shutter doors are: external shutter doors, Australian shutter doors, tubular shutter doors, fire shutter doors, inorganic double shutter doors, quick shutter doors, etc.

From the door material is divided into:

Inorganic cloth shutter doors, mesh shutter doors, European shutter doors, aluminum alloy shutter doors, crystal shutter doors, [1] stainless steel shutter doors, color plate shutter doors, shutter doors,

From the purpose is divided into:

Ordinary shutter doors, windproof shutter doors, fireproof shutter doors, quick shutter doors.

What is the basic working principle of electric Australian (silent) shutter door stainless steel shutter door? .

First of all, the translation automatic door group consists of the following components:

1. main controller: it is the command center of the automatic door, and sends out corresponding instructions through a large-scale integrated block with instruction program to command the motor or electric lock system to work; At the same time, people adjust the opening speed, opening range and other parameters of the door leaf through the main controller.

2. Induction detector: responsible for collecting external signals, just like human eyes. When the moving object enters its working range, a pulse signal is given to the main controller;

3. Power motor: provides the main power for opening and closing the door and controls the acceleration and deceleration of the door leaf.

4. Door leaf moving track: Just like the railway track of a train, the expander wheel system of the door leaf is restricted to move in a specific direction.

5. Gear train of door leaf spreader: used to hang movable door leaves and drive them to run under power traction.

6. Synchronous belt (some manufacturers use V belt): a gear train used to transmit the power generated by the motor and pull the door leaf spreader.

7. Lower guide system: it is the guide and positioning device at the lower part of the door leaf to prevent the door leaf from swinging back and forth during operation.

When the door leaf is to be opened and closed at the same time, its working process is as follows:

When the induction detector detects someone entering, it sends a pulse signal to the main controller, and the main controller informs the motor to run after judgment, and at the same time monitors the number of revolutions of the motor to inform the motor to apply force at a certain time and enter a slow running. After the motor gets a certain running current, it runs forward to transmit power to the synchronous belt, and then the synchronous belt transmits power to the spreader system to open the door leaf; After the door leaf is opened, the controller will make a judgment. If it is necessary to close the door, the motor will be informed to move in the opposite direction to close the door leaf.

Application scope and function of rolling shutter door

Rolling doors are suitable for hotels, hotels, banks, office buildings, hospitals, shops and so on, and are widely used. Using automatic doors can save air conditioning energy, reduce noise, prevent wind and dust, and make our entrances and exits look solemn and upscale.
