Integrity is the foundation of Hefei's fast rolling shutter doors, and quality assurance is guaranteed

Description :

  Fast rolling door is an industrial door designed specifically for the rapid flow of materials (to shorten entry and exit time) and accurately positioned. It is commonly used in places with high environmental requirements such as food, electronics, and printing. Its main function is to quickly isolate and ensure the dust-free level of workshop air quality. It has the characteristics of speed, safety, and reliability.

Framework system: The main material is made of carbon steel plate or aluminum alloy.                     Integrity is the foundation of Hefei's fast rolling shutter doors, and quality assurance is guaranteed

Door curtain system: mainly composed of PVC woven fabric or aluminum alloy profiles. Drive motor system: mainly composed of brake pads, motors, and reducers.

Control system: Commonly used are integrated circuit boards with complete sets of PLC/frequency converters/encoders or built-in IPM modules. The control systems adopted by domestic door industry enterprises are mostly based on PLC/frequency converters/encoders.

Safety system: mainly includes infrared electric eye switches, safety air pressure sensors (some enterprises with high mechanical precision and high stability control systems use safety contact belts) or light curtain systems; The light curtain system should be secure and protected Lifting speed: 0.8m/s-1.5m/s, generally takes about 2 seconds from bottom to top (20 times the speed of an electric roller shutter), vehicles and pedestrians do not need to wait and do not constitute obstacles.

There are multiple ways to trigger the door opening signal: manual button, radar sensing, infrared photoelectric sensing, geomagnetic sensing, remote control, etc.

Door fabric material: PVC or PVDF film is generally used as cord fabric, especially PVDF film has better anti-aging performance, is not easy to fade and has self-cleaning function, so it is very suitable for fast rolling doors. The origin is selected from German or French products. Thickness ranging from 0.8mm to 2.0mm. A 2.0mm thick door panel will alter the entire product structure. There are colors such as orange, yellow, blue, silver, transparent grid, black, etc. Orange is chosen because it is very eye-catching, stimulates the perception of insects, and has a certain anti insect function.

Drive motor: The fast rolling doors are equipped with braking deceleration motors, which require fast braking and low noise. Generally, the brake motors sold in the market either have poor braking effect or high braking noise, and are not suitable for fast rolling doors. A speed ratio of 1:10-1:15 is more suitable. This is a brand new control method that does not require the use of brakes to stop running, further reducing the noise level.
