The Drive System of Hard Fast Doors?

The hard fast door is mainly composed of track, door panel and drive system. That is to say, the structure of the hard fast door has been modularized, and basically, the components have been assembled before the factory leaving, and three modular parts are formed, which can be assembled on site, and is simple and convenient. Master's hard fast door is mainly connected of hinge, 0.7mm aluminum plate thickness, foam door plate thickness 40mm, 50mm series connection, note that when the hinge and door panel are fixed, ensure the seal between the door panel and the door panel tight. Then connect all the door panels into a sheet-like chain system. The hinge chain on both sides has high-quality rolling bearing wheels, and the bearing wheels roll in the rails on both sides. Due to the consideration of friction and wear, the track must be made of aluminum alloy, and when the two sides of the track extend upward, the top end adopts The spiral track, that is, the principle of the Archimedes spiral, is used to fix the spiral track whose arc radius is linearly reduced at the top of the track on both sides. When the door body is drawn into the spiral track, the door body is mutually no collisions between them.


For the hard fast doors drive configuration, the safe drive content that can be configured is as follows:

In consider of the high speed PVC roll up door’s safety, we can provide the photo cell, wireless safety airbag device; about the high speed PVC roll up door’s light transmitting, we can provide the different style transparent window; about the different control way, we can provide the manual button, transmitter, control box, radar sensor, geomagnetism.  

The high speed PVC roll up door’s speed

The high speed PVC roll up door up speed is 0.8-2.0m/s, down speed is 0.6-1.0m/s, and the speed can be adjusted by the actual needs of inverter.

The high speed PVC roll up door’s drive system

The high speed PVC roll up door’s drive system can provide the below brand: SEW, Siemen, SNMA,SEJ, servo system, and the motor is with hand brake. The power is provided according to the door size, the voltage can be 380V/220V

The high speed PVC roll up door’s control system

The high speed PVC roll up door’s control system is adopted PLC digital programming, to achieve the safety passing of vehicle and goods, and the inverter can be adjusted the speed. We can provide the brand of inverter: Mitsubishi, Siemens, SHILIN; the brand of PLC: Mitsubishi, Siemens,KEWEI. 


The door body is fixed to the rails on both sides, the motor drives the reel, the reel drives the sprocket on both sides, the sprocket on both sides drives the chain on both sides, and the bottom of the chain and the bottom of the bottom of the door body are fixed by the connecting piece. . When the motor rotates, the chain is driven to rotate, and the chain drives the door to slide upward and spirally rotate in the spiral track. 


Of course, if there is no auxiliary part, the motor drives the door body, the load is too large, and it is easy to damage. Therefore, a general hard quick door will be provided with a nylon guide wheel beside the sprocket on both sides. The nylon bag is wound on the nylon guide wheel, and the nylon bags on both sides are respectively connected with the tension springs on both sides, and the pulling force of the spring and the power of the door body are reversely applied to the reel, thus reducing the load of the motor.
