　　In the field of flexible packaging production, the horizontal butyl rubber coating machine has become a core equipment in industries such as photovoltaic modules and building sealing due to its high-precision coating capability. The transmission system, as the "nerve center" of equipment operation, directly determines the uniformity of coating, production efficiency, and operational stability. This article will systematically explain the maintenance points of the transmission system from both technical principles and engineering practice, providing the industry with a practical and theoretical operation guide.

　　一、傳動(dòng)系統(tǒng)技術(shù)架構(gòu)解析

　　1、 Analysis of Transmission System Technical Architecture

　　臥式丁基膠涂布機(jī)傳動(dòng)系統(tǒng)由伺服電機(jī)、行星減速機(jī)、同步帶輪、張緊裝置及涂布輥組成。其核心功能是實(shí)現(xiàn)膠料輸送速度與涂布輥轉(zhuǎn)速的精準(zhǔn)匹配，確保膠層厚度偏差控制在±2μm以內(nèi)。系統(tǒng)工作原理如下：

　　The transmission system of the horizontal butyl rubber coating machine consists of a servo motor, planetary reducer, synchronous belt pulley, tensioning device, and coating roller. Its core function is to achieve precise matching between the conveying speed of the adhesive material and the speed of the coating roller, ensuring that the thickness deviation of the adhesive layer is controlled within ± 2 μ m. The working principle of the system is as follows:

　　動(dòng)力傳輸路徑：伺服電機(jī)輸出扭矩經(jīng)行星減速機(jī)放大后，通過同步帶傳遞至涂布輥。張緊裝置動(dòng)態(tài)調(diào)節(jié)皮帶張力，防止打滑現(xiàn)象。

　　Power transmission path: The output torque of the servo motor is amplified by the planetary reducer and transmitted to the coating roller through the synchronous belt. The tensioning device dynamically adjusts the belt tension to prevent slipping.

　　速度閉環(huán)控制：編碼器實(shí)時(shí)采集涂布輥轉(zhuǎn)速，與設(shè)定值比對(duì)后，由伺服驅(qū)動(dòng)器調(diào)整電機(jī)輸出，形成全數(shù)字閉環(huán)控制系統(tǒng)。

　　Speed closed-loop control: The encoder real-time collects the speed of the coating roller, compares it with the set value, and adjusts the motor output by the servo driver to form a fully digital closed-loop control system.

　　負(fù)載均衡機(jī)制：雙輥傳動(dòng)結(jié)構(gòu)采用剛性聯(lián)軸器連接，通過預(yù)緊力調(diào)節(jié)裝置，確保兩輥線速度差值小于0.5%。

　　Load balancing mechanism: The dual roller transmission structure is connected by a rigid coupling, and the pre tension adjustment device is used to ensure that the difference in linear velocity between the two rollers is less than 0.5%.

　　二、關(guān)鍵部件維護(hù)策略

　　Dynamic tension management: Laser centering instrument is used to detect the belt span, and the pre tension force is adjusted through the tensioning wheel bolt. It is recommended to calibrate the belt tension meter weekly to ensure that the tension value is within ± 5% of the standard value.

　　磨損監(jiān)測(cè)技術(shù)：在皮帶側(cè)面設(shè)置磨損標(biāo)記線，當(dāng)標(biāo)記線消失時(shí)，表明皮帶齒高磨損超過20%，需立即更換。同步帶輪齒面應(yīng)保持清潔，避免膠料殘留導(dǎo)致異常磨損。

　　Wear monitoring technology: Set wear marking lines on the side of the belt. When the marking lines disappear, it indicates that the belt teeth have worn more than 20% and need to be replaced immediately. The tooth surface of the synchronous belt should be kept clean to avoid abnormal wear caused by residual rubber material.
