濟南卷簾門作為建筑出入口常見的防護設施，廣泛應用于商鋪、倉庫、車庫等場所，其組成結構融合了機械傳動與防護功能，各部件協(xié)同工作實現(xiàn)門體的升降與鎖閉。了解卷簾門的組成及功能，對選擇適配產品、日常維護保養(yǎng)具有重要意義。

　　Jinan rolling shutter doors, as a common protective facility at building entrances and exits, are widely used in places such as shops, warehouses, and garages. Their structural composition integrates mechanical transmission and safety protection functions, and the various components work together to achieve the lifting and locking of the door body. Understanding the composition and functions of rolling shutter doors is of great significance for selecting suitable products and daily maintenance.

　　驅動系統(tǒng)是卷簾門的動力核心，決定門體運行的穩(wěn)定性與效率。該系統(tǒng)主要由電機、減速器和傳動鏈條構成。電機作為動力源，根據門體重量選擇功率，小型卷簾門（如商鋪門）多采用 0.75-1.5 千瓦的單相電機，大型工業(yè)卷簾門則需 3-5 千瓦的三相電機，以確保門體升降順暢。減速器與電機相連，通過齒輪減速將高速旋轉轉化為適合門體運動的低速扭矩，避免門體因速度過快導致沖擊變形。傳動鏈條連接減速器與卷軸，電機運轉時通過鏈條帶動卷軸轉動，進而實現(xiàn)門體升降，鏈條表面經過防銹處理，能適應濟南潮濕多雨的氣候，減少銹蝕卡頓。部分高端卷簾門配備變頻電機，可通過調節(jié)轉速實現(xiàn)門體軟啟動、軟停止，降低運行噪音，適合居民區(qū)附近的商鋪使用。

　　The drive system is the power core of the rolling shutter door, determining the stability and efficiency of the door's operation. The system mainly consists of a motor, a reducer, and a transmission chain. As a power source, the motor is used to select the power according to the weight of the door. Small rolling shutter doors (such as shop doors) often use single-phase motors of 0.75-1.5 kilowatts, while large industrial rolling shutter doors require three-phase motors of 3-5 kilowatts to ensure smooth lifting and lowering of the door. The reducer is connected to the motor and converts high-speed rotation into low-speed torque suitable for the movement of the door body through gear reduction, avoiding impact deformation of the door body due to excessive speed. The transmission chain connects the reducer and the spool, and the motor drives the spool to rotate through the chain, thereby achieving the lifting and lowering of the door. The high-quality chain surface has been treated with rust prevention to adapt to the humid and rainy climate in Jinan and reduce rust and jamming. Some high-end rolling shutter doors are equipped with variable frequency motors, which can achieve soft start and soft stop of the door body by adjusting the speed, reducing operating noise and suitable for use in shops near residential areas.

　　門體結構是卷簾門的防護主體，承擔著防盜、防風、隔熱等功能。簾片是門體的核心部件，濟南市場上常見的簾片材質有鍍鋅鋼板、鋁合金和復合板材。鍍鋅鋼板簾片厚度多為 0.3-0.8 毫米，表面經靜電噴涂處理，具有抗腐蝕、耐磨的特點，適合倉庫等對防護性要求高的場所；鋁合金簾片質地輕便，色澤多樣，常用于商鋪提升美觀度；復合板材簾片由兩層金屬板夾保溫層（如聚氨酯發(fā)泡）組成，隔熱性能優(yōu)異，適合需要恒溫環(huán)境的場所（如食品倉庫）。簾片之間通過鉸鏈連接，確保門體卷曲靈活，連接處的密封膠條可增強防風性，減少濟南冬季寒風滲入。卷軸作為支撐簾片的部件，采用無縫鋼管制成，長度與門體寬度匹配，兩端安裝軸承座，保證旋轉平穩(wěn)，避免門體升降時出現(xiàn)傾斜。

　　The door structure is the main protective body of the rolling shutter door, which undertakes functions such as anti-theft, windproof, and thermal insulation. The curtain is the core component of the door body, and common curtain materials in the Jinan market include galvanized steel plate, aluminum alloy, and composite sheet. The thickness of galvanized steel sheet curtains is mostly 0.3-0.8 millimeters, and the surface is treated with electrostatic spraying, which has the characteristics of corrosion resistance and wear resistance, suitable for places with high protection requirements such as warehouses; Aluminum alloy curtains are lightweight and come in a variety of colors, often used in shops to enhance their aesthetic appeal; The composite panel curtain is composed of two layers of metal plates sandwiching an insulation layer (such as polyurethane foam), which has excellent thermal insulation performance and is suitable for places that require a constant temperature environment (such as food warehouses). The curtains are connected by hinges to ensure flexible curling of the door body. The sealing strip at the connection can enhance wind resistance and reduce the infiltration of cold winds in Jinan during winter. The scroll, as a component supporting the curtain, is made of seamless steel pipe, with a length that matches the width of the door body. Bearing seats are installed at both ends to ensure smooth rotation and avoid tilting when the door body is lifted or lowered.

　　控制系統(tǒng)負責卷簾門的操作與保護，是人機交互的關鍵。手動控制系統(tǒng)適用于小型卷簾門，由手拉鏈條和限位器組成，拉動鏈條帶動卷軸轉動，限位器可設定門體升降的上下極限位置，防止過度運行導致部件損壞。電動控制系統(tǒng)則通過遙控器、控制面板實現(xiàn)操作，包含控制箱、傳感器和備用電源。控制箱內的電路板接收指令并控制電機運轉，濟南多風天氣時，部分控制系統(tǒng)配備風感傳感器，遇強風會自動關閉門體，防止門體被吹變形。紅外傳感器安裝在門體下方兩側，當檢測到有物體通過時，會立即停止門體下降，避免夾傷行人或車輛，尤其適合頻繁開關的倉庫入口。備用電源在停電時自動啟動，確保門體能正常關閉，應對濟南夏季偶發(fā)的停電情況。

　　The control system is responsible for the operation and safety protection of the rolling shutter door, and is the key to human-computer interaction. The manual control system is suitable for small rolling shutter doors, consisting of a hand zipper strip and a limiter. Pulling the chain drives the scroll to rotate, and the limiter can set the upper and lower limit positions of the door body to prevent component damage caused by excessive operation. The electric control system is operated through a remote control and control panel, including a control box, sensors, and backup power supply. The circuit board inside the control box receives instructions and controls the operation of the motor. During windy weather in Jinan, some control systems are equipped with wind sensors, which automatically close the door in case of strong winds to prevent deformation. Infrared sensors are installed on both sides below the door. When an object is detected passing through, the door will immediately stop descending to avoid injuring pedestrians or vehicles, especially suitable for warehouse entrances that are frequently opened and closed. The backup power supply automatically starts in the event of a power outage, ensuring that the door can be closed normally to cope with occasional power outages in Jinan during summer.

　　導向與鎖具系統(tǒng)保障門體運行軌跡與關閉。導向軌道安裝在門體兩側，材質為冷軋鋼板，軌道內側設有凹槽，簾片邊緣嵌入凹槽內，引導門體沿固定軌跡升降，防止偏移。軌道與墻體連接處用膨脹螺栓固定，深度不小于 10 厘米，確保能承受門體自重及風力沖擊，濟南春季多風，牢固的軌道可避免門體晃動。鎖具系統(tǒng)分為手動鎖和電子鎖，手動鎖安裝在門體底部，關閉后通過鑰匙鎖定，適合無人值守的倉庫；電子鎖與控制系統(tǒng)聯(lián)動，門體關閉后自動上鎖，支持密碼、刷卡或指紋解鎖，提升防盜等級，適合高端商鋪或辦公場所。部分卷簾門還配備防撬裝置，當門體被強行撬動時，會觸發(fā)警報器，增強防護。

　　The guidance and locking system ensures the safe operation trajectory and closure of the door body. The guide track is installed on both sides of the door body, made of cold-rolled steel plate. There is a groove on the inner side of the track, and the edge of the curtain is embedded in the groove. The guide door body rises and falls along a fixed trajectory to prevent deviation. The connection between the track and the wall is fixed with expansion bolts, with a depth of not less than 10 centimeters, to ensure that it can withstand the self weight of the door and wind impact. Jinan is windy in spring, and a sturdy track can prevent the door from shaking. The lock system is divided into manual locks and electronic locks. The manual lock is installed at the bottom of the door and can be locked with a key after being closed, making it suitable for unmanned warehouses; The electronic lock is linked with the control system, automatically locking the door after it is closed. It supports password, card swiping, or fingerprint unlocking, enhancing the anti-theft level and suitable for high-end shops or office spaces. Some rolling shutter doors are also equipped with anti pry devices. When the door is forcibly pried, an alarm will be triggered to enhance safety protection.
