Olide autodoor

Automatic door closing mechanism is similar to the automatic door opening mechanism. The only difference between the two is that the closing mechanism is mainly used to close or shut doors. The use of automatic door closing mechanism is important especially in ships and cruises that travel on water. All doors in ships or cruises are equipped with an automatic door closing mechanism that will close the door automatically if it's flooded with water to avoid the water from flooding other sections of the ship. This mechanism is widely used in every ship.

DC 24V Brushless Motor Worm gear reduce make it low noise; Advanced PWM Pulse width control mode providing reliable strong driving force and protect the stable operation of the product; Full enclosed structure ensure long service life.
	Sparete transformer,elelctric voltage and       electric current transform easily. 32 bit microprocessor in electric board make the door sliding reversely when touch obstacles; Opening&closing parameters can be intelligently ajusted by control panel without extra programmer; Separate transformer with control panel,electric voltage and electric current can transform easily.
One more reducer wheel,more stable and low noise One more reduce wheel make the teeth belt more stable and low operation noise, The roller is made of polyurethane,it is durable and light. The large space between the wheels make little friction between the belt and wheel.
	Complete perfect access control system Only entering the passcode or swiping card on the optional  access keypad,people can be entered. Autodoor can reach the functions of automatic/exit only/partial open/locked and open by the optional five key selector. Various optional accessories such as foot sensor,touch sensor,push button etc.can be equipped.
Functions of Safty beam and microwave sensor          are perfectly combined. The optional active rader&infrared safety sensor is combined the function of safety beam and microwave sensor If install it, no need safety beam and microwave sensor.More intelligent and convenient ,only  need one wire connection, no need more for safety beam and microwave sensor.
Special slot connect with beam and cover Cover opening and closing more convinient                                  SD 280 cover and beam                                                         SD 280 cover and beam

Our standard size for the cover and transmission rail is 2*210cm,it is just like the picture one double leaf door shows.If door size is beyond it ,Or if it is single leaf door,please contact us to choose the correct size for you.

But with today's demand for buildings and establishments that require an automatic door closing mechanism, companies that manufacture an automatic door closing mechanism for ships and cruises developed the perfect mechanism for buildings. Generally, all buildings and facilities are required to have an emergency door that can be used in case of emergencies like fire and earthquake. Emergency doors used in building are equipped with an automatic door closing mechanism. These doors are programmed to close automatically when a fire occurred in one section of the building, preventing the further spread of the fire and smoke to other sections of the building.

Dynamical system OF Automatic door closing mechanism:

1. A motor provides the main force for opening and closing, and controls the acceleration and deceleration of door leaf operation.
2. The tracks that the door leaf moves along constrain the spreader and wheel system to move in a particular direction.
3. The spreader and wheel system is used for hanging door leaves, and drives them run under the dynamic traction.
4. Synchronous belt (some factories use triangle belt) is used to transmit power produced by motor, and then draw the spreader and wheel system.
5. The guiding system is a device set under the door leaf for orientation and positioning, and it can prevent the door leaves from swinging back and forth when in operation.

Automatic door closing mechanism is also used in vaults in some banks. This mechanism closes the vault temporarily and will only open according to its program. Bank vaults require large and heavy doors made from the hardest material, so it must also be installed by a heavy duty automatic door closing mechanism that can support the entire weight of the door and keep it close until the time it is opened. Today, some houses also use an automatic door closing mechanism especially on garage doors. It provides safety to the garage and also to the house. When the owner leaves the house, the garage door will automatically shut the garage door to prevent anyone from opening it. Only with the use of a remote or a code that the automatic door closing mechanism can be disabled.
The use of an automatic door closer in buildings and houses assures the safety of all its occupants. This mechanism that can be connected to any emergency door system and it will automatically close whenever the system detects smoke or fire. The spread of fire can be isolated in just one section, preventing further damage to other sections that can affect its occupants. The main purpose of an automatic door closing mechanism is to provide safety when it is needed the most.
