　　卷帘门主要由帘板、导轨和传动装置组成。济南卷帘门开启时不占用室内外面积，适用于不常开启的高大开口。卷帘门的宽度要与帘板的刚性相适应，对其加工、制作、安装的要求也比较高。

　　Rolling shutter door is mainly composed of curtain plate, guide rail and transmission device. Jinan rolling shutter door does not occupy the indoor and outdoor area when it is opened, and it is suitable for the tall opening that is not often opened. The width of the rolling shutter door should adapt to the rigidity of the curtain plate, and the requirements for its processing, production and installation are also relatively high.

　　帘板的形式主要有页版式和空版式两种，其中页版式使用较多。板式窗帘由镀锌钢板或铝合金板轧制而成。板通过铆钉连接。为加强济南卷帘门的刚性，方便门锁的安装，页板下部采用钢板和角钢，页板上部与卷筒连接.开门时，板沿门洞两侧的导轨上升，在卷筒上滚动。

　　There are two main forms of curtain plate: page format and empty format, of which page format is used more. Panel curtain is made of galvanized steel plate or aluminum alloy plate rolled. The plates are connected by rivets. In order to strengthen the rigidity of ji 'nan rolling shutter door and facilitate the installation of the door lock, the lower part of the page is made of steel plate and Angle steel, and the upper part of the page is connected with the drum. When opening the door, the board rises along the guide rail on both sides of the door hole and rolls on the drum.

　　济南卷帘门厂认为正常来讲，无论是哪一种卷帘门，两边的导轨内部都是有一层“磨擦条”存在的，这层摩擦条的作用是避免帘板与导轨摩擦而存在的。当卷帘门无法上拉、下拉时，要检查的就是导轨的摩擦条。摩擦条属于易消耗品，经常推拉卷帘门会导致摩擦条损耗，如果没有了摩擦条，卷帘门会跟导轨直接接触，就会出现卷帘门无法上拉、下拉的故障。

　　Ji 'nan rolling shutter door factory thinks that normally, no matter what kind of rolling shutter door, there is a layer of friction inside the guide rail on both sides. The role of this layer of friction is to avoid the friction between the curtain plate and the guide rail. When the rolling shutter door cannot be pulled up and down, the first thing to check is the friction bar of the guide rail. Friction strip belongs to consumable goods, often push and pull rolling shutter door will lead to friction strip loss, if there is no friction strip, rolling shutter door will be in direct contact with the guide rail, there will be rolling shutter door can not pull up, pull down the fault.

　　卷帘门的传动装置安装在门洞的上部。本装置分为手动式、链条式、摇臂式和电动式四种。手动卷帘门的传动装置包括滚筒、支架、弹簧轴承等，它是利用弹簧轴承来平衡门的自重，所以这种门不宜过大。底部加强板的两端装有插在侧轨中的销钉以固定门。

　　The driving device of the rolling shutter door is installed on the upper part of the door opening. The device is divided into manual, chain, rocker arm and electric four. The transmission device of manual rolling shutter door includes drum, bracket, spring bearing, etc. It uses spring bearing to balance the weight of the door, so this door should not be too large. Both ends of the bottom stiffeners are fitted with pins inserted into the side rails to secure the door.

　　链条式济南卷帘由链条和几个不同直径的齿轮传动，以减轻启闭重量。摇杆式卷帘门采用摇杆和锥齿轮改变传动方向，切换方便。电动卷帘门的电机多安装在上部，外露或安装在墙上，减速器可与电机分离或设计成一体。电动卷帘门的传动装置包括卷筒、托辊、电机、减速机等，减速机应配备手动装置，以备断电时卷帘门的启闭。

　　Chain type Ji 'nan shutter is driven by a chain and several gears of different diameters to reduce the weight of opening and closing. Rocker type rolling shutter door adopts rocker and bevel gear to change the transmission direction, convenient switching. The motor of the electric rolling shutter door is mostly installed on the upper part, exposed or installed on the wall. The reducer can be separated from the motor or designed into one.
