　　(1) The superior performance of fast rolling shutter doors: strong sealing, no dust accumulation, high stability, easy cleaning, in compliance with GMP requirements, clean environment, commonly used in modern industrial plants, for dust-free workshops, food, electronics, chemistry, printing, textiles, supermarkets, precision machinery, logistics and warehousing, and area isolation in clean industrial plants. It has insulation, dust prevention, noise reduction, and odor isolation properties. Energy saving, high-speed automatic opening and closing. (2) Applicability: Any internal or external door of the factory building. When the wind pressure on the outer door is high, it can provide a stacked fast door that can resist strong winds. The opening speed is 0.6-1.5 meters per second (equipped with a variable frequency converter for adjustable speed), achieving high-frequency opening of more than 1500 times throughout the day without any faults. (3) Safety light: Infrared safety light is installed at a height of about 50 centimeters from the ground at the bottom of the door. When the door is closed and a person or vehicle passes by the safety light, the door will automatically stop descending and ascend to provide safety. (4) Door bottom airbag: In the process of closing the door, if a person or vehicle cannot avoid it in time, the door bottom airbag will transmit pressure to the airbag from the person or vehicle, causing the airbag circuit to work. The door will automatically lift up to provide safety. (5) Low voltage safety power supply: The control system uses a low-voltage safety power supply, and the grounding terminal connection provides a dedicated ground wire. (6) Sealing performance: The bottom of the door curtain is equipped with a weighted air barrier cloth, which can be tightly combined with various uneven surfaces. The door frame is equipped with sliding track sealing strips on both sides Make the sealing tighter.

　　2. Quick Soft Door

　　Quick soft door "is another name for" quick door "and" quick rolling shutter door ". It is a barrier free isolation door that can be quickly lifted and lowered. Its main functions are insulation, moisture retention, dust prevention, insect prevention, sound insulation, etc., to maintain a constant temperature, humidity, and clean working environment in the workshop.

　　Introduction

　　Suitable for fields such as food, medicine, electronics, rubber, chemical, automotive, textile, logistics, etc.

　　working principle

　　Fast doors are currently one of the more reliable industrial doors on the market. Fast rolling doors belong to automation control equipment, consisting of door frames, PVC door curtains, drive motors, and control systems.

　　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 place of origin is German or French. Thickness ranging from 0.8mm to 2.0mm. There are colors such as orange, yellow, blue, silver, transparent grid, black, etc. Orange is chosen because it is very eye-catching, has a warning effect, and also 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.

　　Working process: The trigger signal is provided by the door opening sensor to the control system. The control system sends instructions to the frequency converter based on the current position of the fast rolling door, starts the driving motor to quickly raise the door curtain, and the vehicle and pedestrians automatically descend through the rear door curtain, closing the passage until the next door opening signal opens again. As the name suggests, the lifting speed of a fast rolling shutter is very fast and cannot be started or stopped directly like a steel rolling shutter. Generally, a frequency converter is needed to control the motor speed. The faster the ascent, the better. When approaching quickly (around 20cm), there needs to be a deceleration buffer stop process to prevent collision with the track, prevent people from getting caught, and reduce noise. This is also a standard for measuring the performance of a fast rolling door.

　　There are two ways to quickly locate the rolling door:

　　Mechanical positioning: This positioning method is similar to that of steel coil gates, with the advantages of fast speed and low controller requirements.

　　Rotary encoder positioning: The elevators we often ride on use rotary encoders for positioning. The advantage of this method is accurate positioning. Taking an encoder with a resolution of 1024 as an example, a 3-meter-high door is divided into nearly 9000 points, and theoretically the degree can reach 0.3mm. The height setting is simple, and the fast rolling door control system only has one button to set the height arbitrarily. This is very practical. If only people are passing through, setting the height to 2 meters is enough to avoid futile opening. If there are tall objects such as forklifts passing through, resetting the height is enough. The disadvantage is that the rotary encoder itself has a high price, is a delicate precision component, and needs to be used in conjunction with PLC programs, so the cost of the control system is relatively high.

　　development trend

　　Fast rolling doors have been popular in developed industrial countries such as Europe, America, and Japan for many years. Especially for production-oriented enterprises, there must be fast rolling doors between workshops. If it is a food or pharmaceutical enterprise, it is mandatory to use fast rolling doors for isolation to prevent secondary contamination of products. Just like our country's mandatory requirement for certain industries to install fire doors (whether you like it or not), factories cannot start production without fire doors.

　　The domestic fast rolling door industry started relatively late, but its development speed is very fast, increasing at a rate of about 40% per year. Large scale enterprises have gradually developed the awareness of installing fast rolling doors. Firstly, it is indeed of great help in improving product quality and reducing energy consumption. Secondly, it can enhance the overall image of the company.

　　The imported brand of fast rolling doors has good safety protection and quality performance.

　　Quick rolling doors will soon become a must-have equipment for enterprises. The trend towards standardized design, development, production, and installation of fast rolling doors is inevitable.
