What is the role of PVC quick door counterweight equipment

　　Because PVC quick doors do not have a balance weight device, when opening or closing the rolling shutter door is unstable, the vibration is large, and the motor requires a large output power, which can only be applied to smaller size door openings. In order to meet the above technical deficiencies, a quick door weighting device can make the door of the PVC quick door smoother when opening and closing, and the operation is more stable and reliable.

　　The counterweight device of the PVC quick door includes a reel installed above the door hole, a rotating shaft is provided in the reel, and the curtain is wound on the rotating shaft. The power output end is connected, and the motor is installed on the upper side of the door hole; its characteristic is that a weight is provided on the end of the rotating shaft away from the motor.

　　The counterweight is arranged in the longitudinal rail at the end of the drum, and the counterweight can move up and down along the longitudinal rail. The counterweight device of the PVC quick door installs the counterweight on one end of the reel. When the motor works, the counterweight moves downward or upward with the opening and closing of the curtain, which can make the quick door open. Closing work is more smooth, smooth and reliable.

　　The counterweight device of the PVC quick door has a simple structure, which can make the quick door run more smoothly, reduce the noise and vibration during operation, and reduce the power of the required motor, thereby greatly reducing the manufacturing cost, especially suitable for the size of the door opening. On the roller shutter door at the time.
