中空玻璃丁基膠涂布機在生產(chǎn)作業(yè)中，常因涂布質量、加熱系統(tǒng)、機械系統(tǒng)等方面出現(xiàn)問題，影響產(chǎn)品質量與生產(chǎn)效率，以下將針對這些常見問題進行深入分析并提供有效解決方案。 Hollow glass butyl rubber coating machine often encounters problems in coating quality, heating system, mechanical system, etc. during production operations, which affect product quality and production efficiency. The following will provide in-depth analysis and effective solutions to these common problems. 在涂布質量問題上，膠條不連續(xù) / 斷膠現(xiàn)象主要由膠料溫度異常、齒輪泵磨損以及膠嘴堵塞引發(fā)。當膠料溫度偏離最佳工作溫度 120 - 140℃時，膠料流動性改變，易導致斷膠；齒輪泵磨損使流量波動超過 5%，無法穩(wěn)定供膠；膠嘴內殘留膠碳化堵塞通道，同樣會造成膠條不連續(xù)。而膠條厚度不均則可通過精準調整來改善，校準刮刀間隙至公差 ±0.05mm，確保涂布厚度一致；檢查傳送帶速度穩(wěn)定性，將波動控制在＜1%，避免因速度變化影響涂布；預熱鋁條至 60 - 80℃，使膠料與鋁條更好貼合，保證涂布質量。 In terms of coating quality issues, the discontinuity/breakage of the adhesive strip is mainly caused by abnormal temperature of the adhesive material, wear of the gear pump, and blockage of the adhesive nozzle. When the temperature of the adhesive deviates from the optimal working temperature of 120-140 ℃, the flowability of the adhesive changes, which can easily lead to adhesive breakage; The wear of the gear pump causes flow fluctuations exceeding 5%, making it impossible to provide stable adhesive supply; The residual glue inside the nozzle will carbonize and block the channel, which will also cause the glue strip to be discontinuous. The uneven thickness of the adhesive strip can be improved by precise adjustment, calibrating the scraper gap to a tolerance of ± 0.05mm to ensure consistent coating thickness; Check the stability of the conveyor belt speed, control the fluctuation within<1%, and avoid affecting the coating due to speed changes; Preheat the aluminum strip to 60-80 ℃ to ensure better adhesion between the adhesive and the aluminum strip, ensuring coating quality.

加熱系統(tǒng)故障中，溫控精度差表現(xiàn)為多種情況。溫度波動大往往是因為 PID 參數(shù)失調，此時需重新整定，將比例帶控制在 ±5% 以穩(wěn)定溫度；加熱速度慢可能是加熱管老化所致，當電阻值偏差超過 10% 時，應及時更換加熱管；局部過熱則大概率是熱電偶失效，需更換 K/J 類型熱電偶以準確測溫。針對熱熔膠氧化問題，可實施氮氣保護系統(tǒng)，將氧含量控制在＜3%，減少氧化環(huán)境；采用密封式膠箱設計，隔絕空氣；同時設置定時自動攪拌，間隔 15 - 20 分鐘攪拌一次，避免熱熔膠局部過熱氧化。 In heating system failures, poor temperature control accuracy is manifested in various situations. Large temperature fluctuations are often caused by PID parameter imbalance, and in this case, it is necessary to readjust and control the proportional band within ± 5% to stabilize the temperature; Slow heating speed may be caused by aging of the heating tube. When the resistance deviation exceeds 10%, the heating tube should be replaced in a timely manner; Local overheating is highly likely due to thermocouple failure, and K/J type thermocouples need to be replaced for accurate temperature measurement. For the oxidation problem of hot melt adhesive, a nitrogen protection system can be implemented to control the oxygen content at<3% and reduce the oxidation environment; Adopting a sealed rubber box design to isolate air; Simultaneously set up timed automatic stirring, stirring every 15-20 minutes to avoid local overheating and oxidation of the hot melt adhesive. 機械系統(tǒng)問題集中于傳動不同步和鋁條定位偏差。傳動不同步時，需按校準步驟操作，校驗編碼器，確保脈沖誤差＜3，保障傳動精度；調整伺服電機增益，將剛性提升 20%，增強動力傳輸穩(wěn)定性；張緊同步帶，使撓度達到 1.5% 跨距，避免打滑。對于鋁條定位偏差，改進措施包括增加 CCD 視覺定位系統(tǒng)，實現(xiàn) ±0.1mm 的高精度定位；采用真空度為 - 0.06MPa 的真空吸附傳送，穩(wěn)固鋁條位置；安裝響應時間＜10ms 的邊緣檢測傳感器，實時監(jiān)測并糾正鋁條位置偏差，從而提升涂布機整體運行精度與可靠性。 The mechanical system problems focus on asynchronous transmission and aluminum strip positioning deviation. When the transmission is not synchronized, it is necessary to follow the calibration steps to verify the encoder, ensure that the pulse error is less than 3, and guarantee the transmission accuracy; Adjust the gain of the servo motor to increase rigidity by 20% and enhance power transmission stability; Tighten the synchronous belt to achieve a deflection of 1.5% of the span and avoid slipping. For the positioning deviation of aluminum bars, improvement measures include adding a CCD visual positioning system to achieve high-precision positioning of ± 0.1mm; Adopting a vacuum adsorption transfer with a vacuum degree of -0.06MPa to stabilize the position of the aluminum strip; Install edge detection sensors with a response time of less than 10ms to monitor and correct the position deviation of the aluminum strip in real time, thereby improving the overall operational accuracy and reliability of the coating machine.
