The steel rolling shutter door machine is mainly composed of the following parts, forming its unique structural form:
1. Drive system: This is the core power source of the steel rolling shutter door machine, usually using an electric motor. Depending on the size, weight, and usage scenario of the door, different power motors will be selected. The electric motor converts high-speed operation into low-speed high torque motion suitable for the lifting and lowering of rolling shutter doors through a deceleration device. Common reduction devices include worm gear reducers or gear reducers. The former has a large transmission ratio and compact structure, while the latter has high transmission efficiency and strong load-bearing capacity. They can effectively ensure the smooth and slow lifting of rolling shutter doors, meeting practical usage needs.
2. Scroll section: The curtain of the steel roller shutter door is wrapped around the scroll. Rollers are generally made of high-quality steel, with sufficient strength and rigidity to support the weight of rolling shutter door curtains. The scroll is connected to the drive system and rotates under the drive of the drive system, thereby retracting the curtain. To ensure the smooth and stable rotation of the scroll, bearing seats are usually installed at both ends, which are fixed on the walls on both sides of the door or on specialized brackets.
3. Control system: It is the key to achieving intelligent operation of the steel rolling shutter door machine. The control system includes control buttons, remote controllers, and control circuits. The operator can easily achieve the up, down, and stop actions of the rolling shutter door through the control buttons installed on the wall; Remote control can also be used to remotely operate from a certain distance. The control circuit precisely controls the operation of the motor, ensuring the accurate and error free movement of the rolling shutter door. It can also achieve functions such as limit protection to prevent damage to the door due to excessive lifting or lowering.
4. Curtain structure: The curtain is the part that directly constitutes the appearance and protective function of the rolling shutter door. Using steel material and processed through special techniques, adjacent curtains are connected to each other through a connecting structure, which ensures the tightness between curtains and allows them to bend flexibly when the roller is retracted. At the same time, the steel material endows the rolling shutter door with good strength and anti-theft performance.
