雙組份打膠機因能精準混合A、B兩組份膠水，廣泛應用于建筑密封、汽車制造等領域。當生產需求變更需切換不同膠水時，徹底清潔設備是保障后續(xù)生產質量的關鍵。以下從操作步驟、材料選擇到驗收標準，系統(tǒng)闡述清潔全流程。

　　The two-component glue machine is widely used in fields such as building sealing and automotive manufacturing due to its ability to accurately mix adhesive of components A and B. Thoroughly cleaning the equipment is the key to ensuring the quality of subsequent production when different adhesives need to be switched due to changes in production requirements. The following systematically explains the entire cleaning process from operational steps, material selection to acceptance criteria.

　　一、清潔前準備：精準匹配清洗劑

　　1、 Preparation before cleaning: precise matching of cleaning agents

　　需根據(jù)原膠水與新膠水的化學特性選擇清洗劑。例如，聚氨酯膠水推薦使用醋酸乙酯或丙酮，而環(huán)氧樹脂膠則需專用環(huán)氧清洗劑。清洗前需關閉AB料桶底部閥門，防止殘膠倒流污染清洗劑。

　　The cleaning agent should be selected based on the chemical properties of the original adhesive and the new adhesive. For example, polyurethane adhesive is recommended to use ethyl acetate or acetone, while epoxy resin adhesive requires a specialized epoxy cleaning agent. Before cleaning, it is necessary to close the bottom valve of the AB material bucket to prevent residual glue from flowing back and contaminating the cleaning agent.

　　二、核心清潔步驟：從管路到泵體的深度清理

　　2、 Core cleaning steps: Deep cleaning from pipeline to pump body

　　排出殘膠：啟動設備，將膠閥、高壓鐵氟龍管及AB泵內殘膠完全排出。需觀察膠閥出膠口膠量變化，當膠液顏色由混合色轉為單一組份原色時，表明殘膠已排空。

　　Discharge residual glue: Start the equipment and completely discharge the residual glue from the glue valve, high-pressure PTFE tube, and AB pump. It is necessary to observe the change in the amount of glue at the outlet of the glue valve. When the color of the glue liquid changes from a mixed color to a single component original color, it indicates that the residual glue has been emptied.

　　拆卸清洗料桶：關閉設備總電源，拆開料桶底部膠管，將剩余膠水徹底排出。用蘸有清洗劑的干凈抹布擦拭料桶內壁，重點清除桶底與桶壁交界處的膠漬。

　　Disassemble and clean the material bucket: Turn off the main power of the equipment, remove the rubber hose at the bottom of the material bucket, and completely drain the remaining glue. Wipe the inner wall of the material bucket with a clean cloth dipped in cleaning agent, focusing on removing the glue stains at the junction of the bucket bottom and the bucket wall.

　　深度清潔泵體：拆下AB泵，由專業(yè)人員清理泵腔內殘留膠水。需注意，泵體內部齒輪與密封圈為精密部件，需用軟毛刷蘸取清洗劑輕柔刷洗，避免劃傷。

　　Deep cleaning of pump body: Remove the AB pump and have a professional clean the residual glue inside the pump chamber. Please note that the gears and sealing rings inside the pump body are precision components and should be gently brushed with a soft bristled brush dipped in cleaning agent to avoid scratches.

　　更換耗材：高壓鐵氟龍管因內壁易附著膠漬，需每次換膠時更換。靜態(tài)混合管雖可重復使用，但需用清洗劑浸泡后氣槍吹掃。

　　Replacement of consumables: High pressure PTFE pipes are prone to adhesive stains on the inner wall and need to be replaced every time the adhesive is changed. Although the static mixing tube can be reused, it needs to be soaked in cleaning agent and blown with an air gun.

　　三、驗收與測試：三重驗證確保清潔度

　　3、 Acceptance and Testing: Triple Validation to Ensure Cleanliness

　　視覺檢查：用強光手電筒照射管路內壁，無膠漬殘留且呈現(xiàn)金屬本色為合格。

　　Visual inspection: Use a strong flashlight to illuminate the inner wall of the pipeline. If there are no adhesive residue and the metal color appears, it is qualified.

　　壓力測試：重新組裝后，向設備內注入清洗劑，啟動設備觀察壓力表。若壓力穩(wěn)定在正常工作范圍內，表明管路無堵塞。

　　Pressure test: After reassembling, inject cleaning agent into the equipment and start the equipment to observe the pressure gauge. If the pressure remains stable within the normal operating range, it indicates that the pipeline is not blocked.

　　試機驗證：倒入新膠水，點動出膠3-5分鐘，檢查出膠顏色是否均勻，并取樣送檢膠水混合比例。

　　Test machine verification: Pour in new glue, tap the glue for 3-5 minutes, check if the color of the glue is uniform, and take a sample to check the mixing ratio of the glue.

　　四、特殊場景處理：應對頑固膠漬與長時間停機

　　4、 Special scenario handling: Dealing with stubborn glue stains and prolonged downtime

　　頑固膠漬：若管路內有固化膠塊，可用加熱帶將管路包裹，加熱至60℃使膠體軟化，再配合清洗劑沖洗。

　　Stubborn glue stains: If there are solidified glue blocks in the pipeline, the pipeline can be wrapped with a heating belt, heated to 60 ℃ to soften the glue, and then rinsed with a cleaning agent.

　　長期停機：若設備停用超10天，需將儲膠桶內清洗劑排空，用氣槍將管路吹干，并在出膠口涂抹防銹油。

　　Long term shutdown: If the equipment is stopped for more than 10 days, the cleaning agent in the rubber storage tank should be emptied, the pipeline should be dried with an air gun, and rust proof oil should be applied to the rubber outlet.

　　五、維護保養(yǎng)：延長設備壽命的關鍵舉措

　　5、 Maintenance and upkeep: key measures to extend equipment lifespan

　　日常維護：每班次結束后，用清洗劑擦拭機身，排放油水分離器積水。

　　Daily maintenance: After each shift, wipe the machine body with cleaning agent and drain the accumulated water in the oil-water separator.

　　定期保養(yǎng)：每周檢查氣路油霧器油位，每月清洗過濾器與針閥，每年對主泵進行解體清洗。

　　Regular maintenance: Check the oil level of the air path oil mist device weekly, clean the filter and needle valve monthly, and disassemble and clean the main pump annually.

　　通過嚴格執(zhí)行上述流程，可確保雙組份打膠機在膠水切換后穩(wěn)定運行。實際案例表明，規(guī)范清潔能使設備故障率降低，膠水切換時間縮短。企業(yè)可結合自身生產節(jié)拍，制定標準化清潔作業(yè)指導書，并培訓操作人員通過認證，從而構建完善的設備管理體系。

　　By strictly following the above process, the two-component gluing machine can ensure stable operation after glue switching. Practical cases have shown that standardized cleaning can reduce equipment failure rates and shorten glue switching times. Enterprises can develop standardized cleaning operation manuals based on their own production pace, and train operators to pass certification, thereby building a comprehensive equipment management system.
