Electric rolling gate is a kind of rolling gate, which is driven by electricity and is light and flexible. Mostly used in warehouses, shops, etc.
Second, the circuit working principle
1. The door panel is supported by the bracket on the guide rail, which is connected to the driving device. The driving device drives the door panels to slide through the guide rails, and each door has a locking mechanism. When the door is closed in place, the locking mechanism realizes mechanical locking. The door has zero-speed protection and safety interlock circuit, the switch door has alarm device, the driving device of the electric door is a group of motor components, and each car has a main controller to control the door of the car. The main controller is the command center of the automatic door, and sends corresponding instructions through the internal instruction program to command the motor or electric lock system to work; At the same time, people can also adjust the opening speed, opening range and other parameters of the door leaf through the main controller.
2. The external signal is completed by the induction detector. When a moving object enters its working range, it will give a pulse signal to the main controller. The motor provides the main power for opening and closing the door, and the industrial automatic door leaf accelerates and decelerates. The door leaf of the automatic door is opened and closed once, and its working process is as follows: the induction detector sends the detection signal to the main controller, and the main controller controls the motor to run after judgment, and at the same time monitors the motor revolution and current, and controls the motor to apply force at a certain time to enter slow walking and reverse rotation.
3. After the motor gets a certain running current, it runs forward, and the power opens the automatic door leaf through the transmission mechanism; After the automatic shutter door is opened, the controller makes a judgment, controls the motor to rotate reversely and closes the automatic door leaf.
Third, the characteristics:
1. The door body is novel and beautiful in shape, flexible and changeable, compact in structure and small in occupied space, and widely used in the internal and external doors of buildings.
2. The door body is electrically driven, light and flexible, and the up-and-down stroke is automatically controlled by the limit switch, which is convenient to operate, safe and reliable. It can be operated manually in case of power failure.
3. A remote controller can be installed to remotely switch the electric rolling gate.
4. There are many kinds of doors, among which fully enclosed doors have good sealing performance, which can prevent wind, dust, heat preservation and corrosion. After special treatment, the door body can also have the function of fire prevention.
5. The door rolling machine has advanced structure, complete functions and overheating protection device, which can protect the motor from being damaged in overload and high temperature.
