双组份打胶机因能精准混合A、B两组份胶水，广泛应用于建筑密封、汽车制造等领域。当生产需求变更需切换不同胶水时，彻底清洁设备是保障后续生产质量的关键。以下从操作步骤、材料选择到验收标准，系统阐述清洁全流程。

　　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、清洁前准备：精准匹配清洗剂

　　1、 Preparation before cleaning: precise matching of cleaning agents

　　需根据原胶水与新胶水的化学特性选择清洗剂。例如，聚氨酯胶水推荐使用醋酸乙酯或丙酮，而环氧树脂胶则需专用环氧清洗剂。清洗前需关闭AB料桶底部阀门，防止残胶倒流污染清洗剂。

　　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、核心清洁步骤：从管路到泵体的深度清理

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

　　排出残胶：启动设备，将胶阀、高压铁氟龙管及AB泵内残胶完全排出。需观察胶阀出胶口胶量变化，当胶液颜色由混合色转为单一组份原色时，表明残胶已排空。

　　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：关闭设备总电源，拆开料桶底部胶管，将剩余胶水彻底排出。用蘸有清洗剂的干净抹布擦拭料桶内壁，重点清除桶底与桶壁交界处的胶渍。

　　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.

　　深度清洁泵体：拆下AB泵，由专业人员清理泵腔内残留胶水。需注意，泵体内部齿轮与密封圈为精密部件，需用软毛刷蘸取清洗剂轻柔刷洗，避免划伤。

　　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.

　　更换耗材：高压铁氟龙管因内壁易附着胶渍，需每次换胶时更换。静态混合管虽可重复使用，但需用清洗剂浸泡后气枪吹扫。

　　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、验收与测试：三重验证确保清洁度

　　3、 Acceptance and Testing: Triple Validation to Ensure Cleanliness

　　视觉检查：用强光手电筒照射管路内壁，无胶渍残留且呈现金属本色为合格。

　　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.

　　压力测试：重新组装后，向设备内注入清洗剂，启动设备观察压力表。若压力稳定在正常工作范围内，表明管路无堵塞。

　　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.

　　试机验证：倒入新胶水，点动出胶3-5分钟，检查出胶颜色是否均匀，并取样送检胶水混合比例。

　　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、特殊场景处理：应对顽固胶渍与长时间停机

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

　　顽固胶渍：若管路内有固化胶块，可用加热带将管路包裹，加热至60℃使胶体软化，再配合清洗剂冲洗。

　　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.

　　长期停机：若设备停用超10天，需将储胶桶内清洗剂排空，用气枪将管路吹干，并在出胶口涂抹防锈油。

　　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、维护保养：延长设备寿命的关键举措

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

　　日常维护：每班次结束后，用清洗剂擦拭机身，排放油水分离器积水。

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

　　定期保养：每周检查气路油雾器油位，每月清洗过滤器与针阀，每年对主泵进行解体清洗。

　　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.

　　通过严格执行上述流程，可确保双组份打胶机在胶水切换后稳定运行。实际案例表明，规范清洁能使设备故障率降低，胶水切换时间缩短。企业可结合自身生产节拍，制定标准化清洁作业指导书，并培训操作人员通过认证，从而构建完善的设备管理体系。

　　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.
