In the industrial roller gate motor hanging horizontal movement rolling support mechanism, through the motor drive the gearbox worm, turbine rotation, by the output shaft in the drive reel rotation while driving the rolling support in the horizontal movement mechanical mechanism work, and through the rotary disc mechanical double limit mechanism and wall control box cooperation, accurate limiting, so as to drive the door body up and down operation, horizontal movement mechanical mechanism drive the roller shutter motor and reel front and back horizontal movement. This working mode strengthens the sealing of the door body, reduces the wear and friction between the door panels, reduces the operating noise, and improves the long-term operation reliability of the system.
During the opening and closing process of the door curtain of the fast door, the reel can be close to or away from the wall according to the actual need to ensure that the part of the sagging profile entering the guide rail always runs vertically, effectively reducing the friction between the profile and the guide rail, so that the lifting force of the roller shutter motor acts on the lifting profile. Reduce noise and wear, improve the service life of the profile and motor, and ensure the overall force of the profile hook, so as to avoid the phenomenon of decoupling due to the excessive length and weight of the profile and the traditional installation method, and even exceed the force limit of the profile hook from both ends to the middle deformation or tearing.
After the door curtain is closed, the fast door can realize the sealing of the top of the profile because the system shaft is close to the wall, which greatly improves the anti-prying effect and enhances the wind resistance.
The top of the curtain takes up less space, the spindle installation height of the quick door can be reduced, and the number of profiles required is relatively reduced, which can effectively reduce costs.
When the motor drives the reel to rotate, relying on the inertia of the forward rotation power, the entire reel system runs freely in the two sliding grooves of the rolling support. When opened, the reel is away from the wall, and the profile roll diameter increases; When closed, the reel runs closer to the wall and the roll diameter is reduced. Due to the free operation, when the wind acts on the door profile, the top of the profile is easy to stay away from the wall, and a gap appears, and a lintel with a sealing wool strip should be installed at the top of the guide rail to increase the tightness.
Optional when no wind pressure is required. There are few driven rolling support parts and the structure is simple, reflecting better economy.
The reel position of the traditional roller shutter door remains unchanged, the profile is easy to bend, and the fast roller shutter door is easy to cause bow-shaped gaps, and cause more friction and wear at the upper end of the guide rail, with high noise and large headspace. After the European composite roller shutter door is installed with rolling support, the gap between the roller shutter door and the beam is reduced, so that the door body and the building structure are closer together, the effective sealing between the profile and the top is improved, and the wear and friction of the profile are also reduced, so that the door maintains a good appearance; Low noise, more quiet operation of the profile; Saves space for top installation.
