The emergence of fast rolling shutter door improves the requirements for high-performance logistics and clean places, saves energy, improves air conditioning effect, high-speed automatic shutdown and improves efficiency.

卷帘门快速开关门的工作流程

Workflow of quick opening and closing of rolling shutter door

快卷帘门，的名字叫不可思议，就是快速开关门。作为主要产品，公司赢得了企业和用户的信任和好评。在这里，我将向您介绍开门和关门的过程。

Fast rolling shutter door, whose name is incredible, is to open and close quickly. As a main product, the company has won the trust and praise of enterprises and users. Here, I will introduce you to the process of opening and closing the door.

当快速卷帘门感应检测器检测到有人进入时，向主控制器发送脉冲信号，主控制器判断后通知电机运行，同时监测电机的转数，从而在一定时间内通知电机施力进入慢速运行。电机获得一定的运行电流后，向前运行，将动力传递给同步带，再由同步带将动力传递给吊具系统，打开门扇;门扇打开后，控制器会做出判断。如果需要关门，通知电机反向运动并关闭门扇。

When the fast rolling shutter door induction detector detects someone entering, it sends a pulse signal to the main controller. After judgment, the main controller notifies the motor to run, and monitors the number of revolutions of the motor, so as to notify the motor to apply force to enter slow operation within a certain time. After the motor obtains a certain operating current, it runs forward to transmit the power to the synchronous belt, and then the synchronous belt transmits the power to the spreader system to open the door leaf; After the door leaf is opened, the controller will make judgment. If it is necessary to close the door, inform the motor to move in the opposite direction and close the door leaf.

快速卷帘门扭簧安装：

Installation of torsion spring of fast rolling shutter door:

安装前，卷帘门扭簧必须加长80 ~ 150 mm，然后一端固定在轴上，另一端固定在扭套上。轴和扭力套筒都安装在大梁管中。扭转套与桁管用沉头螺钉牢固连接，桁管转动时带动扭转弹簧转动。具体安装如下：

Before installation, the torsion spring of rolling shutter door must be extended by 80 ~ 150 mm, and then one end is fixed on the shaft and the other end is fixed on the torsion sleeve. The shaft and torque sleeve are installed in the girder pipe. The torsion sleeve is firmly connected with the truss pipe with countersunk screws. When the truss pipe rotates, it drives the torsion spring to rotate. The specific installation is as follows:

A.门体放置在：下方(即处于关闭状态)。横梁管不与门板连接，待横梁管带动扭簧旋转到安装所需圈数后，再将门板与横梁管连接。

A. The door body is placed below (i.e. closed). First, the cross beam tube is not connected with the door plate. After the cross beam tube drives the torsion spring to rotate to the number of turns required for installation, connect the door plate with the cross beam tube.

所需安装圈数=门片在大梁管上的圈数，预紧为2 ~ 3圈。

Required installation turns = the number of turns of the door leaf on the girder pipe, and the preload is 2 ~ 3 turns.
