雙組份打膠機的堵塞問題多源于膠料混合不均、雜質(zhì)混入或設備部件殘留，通過規(guī)范操作流程、優(yōu)化維護方式，可有效降低堵塞概率，保障打膠作業(yè)的連續(xù)性。

　　The clogging problem of two-component gluing machines is mainly caused by uneven mixing of rubber materials, impurities, or residual equipment components. By standardizing operating procedures and optimizing maintenance methods, the probability of clogging can be effectively reduced to ensure the continuity of gluing operations.

　　膠料預處理環(huán)節(jié)是減少堵塞的基礎。雙組份膠料（如 A 膠和 B 膠）在使用前需進行充分攪拌，避免因沉淀導致的成分不均 —— 若膠料中存在未分散的顆粒，易在管路或混合腔中形成堆積，逐漸造成堵塞。對于粘度較高的膠料，可在使用前進行預熱（溫度控制在膠料說明書建議范圍內(nèi)），降低流動性阻力，減少在管路內(nèi)的滯留。同時，需過濾膠料中的雜質(zhì)，通過在膠料桶出口加裝濾網(wǎng)（目數(shù)根據(jù)膠料顆粒度選擇，通常為 80-120 目），攔截生產(chǎn)過程中可能混入的灰塵、金屬碎屑等異物，從源頭切斷堵塞物的來源。

　　The pre-treatment process of rubber material is the foundation for reducing blockage. Two component adhesive materials (such as A and B adhesives) need to be thoroughly stirred before use to avoid uneven composition caused by precipitation - if there are undissolved particles in the adhesive material, they can easily accumulate in the pipeline or mixing chamber, gradually causing blockage. For adhesive materials with high viscosity, preheating (temperature control within the recommended range in the adhesive material manual) can be carried out before use to reduce flow resistance and minimize retention in the pipeline. At the same time, impurities in the rubber material need to be filtered by installing a filter screen at the outlet of the rubber material barrel (the mesh size is selected according to the particle size of the rubber material, usually 80-120 mesh) to intercept foreign objects such as dust and metal debris that may be mixed in during the production process, and cut off the source of blockages from the source.

　　設備參數(shù)的精準設置能減少膠料殘留堵塞?；旌媳壤д{(diào)是常見誘因，若 A、B 膠的配比偏差超過 5%，可能導致膠料在混合腔中反應不完全，產(chǎn)生固化顆粒。需定期校準計量泵的輸出精度，通過稱重法檢測單位時間內(nèi)的出膠量，確保配比誤差控制在允許范圍。出膠壓力和速度也需匹配膠料特性，壓力過高易導致膠料在管路內(nèi)過度擠壓形成沉淀，速度過快則可能使膠料在混合腔中混合不充分，建議根據(jù)膠料粘度逐步調(diào)試參數(shù)，以出膠順暢、無明顯飛濺為宜。此外，每次停機前需執(zhí)行 “清洗程序”，通過專用清洗液（如溶劑型膠料用專用稀釋劑）沖洗混合腔和出膠嘴，將殘留膠料徹底排出。

　　Accurate setting of equipment parameters can reduce residual blockage of rubber materials. Mixing ratio imbalance is a common cause. If the ratio deviation of A and B adhesives exceeds 5%, it may lead to incomplete reaction of the adhesive in the mixing chamber, resulting in solidified particles. The output accuracy of the metering pump needs to be calibrated regularly, and the glue output per unit time should be detected by weighing method to ensure that the proportioning error is controlled within the allowable range. The dispensing pressure and speed also need to match the characteristics of the adhesive material. Excessive pressure can easily cause the adhesive material to be excessively squeezed and precipitate in the pipeline, while excessive speed may result in insufficient mixing of the adhesive material in the mixing chamber. It is recommended to gradually adjust the parameters according to the viscosity of the adhesive material to ensure smooth dispensing without obvious splashing. In addition, before each shutdown, a "cleaning procedure" must be performed to thoroughly flush the mixing chamber and dispensing nozzle with a specialized cleaning solution (such as a solvent based adhesive diluent) to remove any residual adhesive.

　　管路與部件的定期維護是防堵塞的關鍵。管路內(nèi)壁若積累膠垢，會縮小流通截面，增加堵塞風險，需每周拆解管路進行清洗 —— 對于軟管，可采用高壓氣流沖洗內(nèi)壁；金屬硬管則可用專用通條清理附著的膠層?；旌锨缓挽o態(tài)混合器是堵塞高發(fā)區(qū)，其內(nèi)部的螺旋葉片易纏繞殘留膠料，需每日作業(yè)結束后拆卸清洗，必要時用軟毛刷清理葉片間隙。出膠嘴的口徑需與膠料粘度匹配，粘度高的膠料應選用較大口徑的噴嘴，避免因流速過慢導致膠料在出口處固化，同時需每日檢查噴嘴是否有膠料殘留，發(fā)現(xiàn)結晶或硬塊及時用專用工具清理。

　　Regular maintenance of pipelines and components is key to preventing blockages. If adhesive deposits accumulate on the inner wall of the pipeline, it will reduce the flow cross-section and increase the risk of blockage. It is necessary to disassemble the pipeline for cleaning every week - for hoses, high-pressure airflow can be used to flush the inner wall; Metal hard pipes can be cleaned of the attached adhesive layer using dedicated strips. The mixing chamber and static mixer are high-risk areas for blockage, and the spiral blades inside are prone to entanglement with residual rubber material. They need to be disassembled and cleaned after daily work, and if necessary, the blade gaps should be cleaned with a soft bristled brush. The diameter of the dispensing nozzle should match the viscosity of the adhesive material. For adhesive materials with high viscosity, larger diameter nozzles should be used to avoid solidification of the adhesive material at the outlet due to slow flow rate. At the same time, the nozzle should be checked daily for any residue of adhesive material, and if crystals or hard blocks are found, they should be cleaned with specialized tools in a timely manner.

　　環(huán)境與儲存條件的控制不可忽視。膠料儲存需密封良好，避免空氣進入形成結皮 —— 結皮的膠塊若混入打膠系統(tǒng)，會直接造成管路堵塞。儲存環(huán)境的溫濕度需符合膠料要求，高溫高濕易導致膠料提前反應，生成固化顆粒，建議將膠料存放于陰涼干燥處，并遵循 “先進先出” 原則，避免過期膠料投入使用。作業(yè)環(huán)境需保持清潔，定期清理工作臺面的膠料殘渣，防止其被意外帶入膠料桶或進料口，同時在設備進料口加裝防塵蓋，減少空氣中的灰塵混入膠料。

　　The control of environment and storage conditions cannot be ignored. The storage of rubber materials should be well sealed to prevent air from entering and forming a crust - if the crust rubber blocks mix into the gluing system, it will directly cause pipeline blockage. The temperature and humidity of the storage environment should meet the requirements of the adhesive material. High temperature and humidity can easily cause the adhesive material to react prematurely and form solidified particles. It is recommended to store the adhesive material in a cool and dry place, and follow the "first in, first out" principle to avoid using expired adhesive material. The working environment needs to be kept clean, and the residue of adhesive on the workbench should be regularly cleaned to prevent it from being accidentally brought into the adhesive bucket or feeding port. At the same time, a dust cover should be installed at the equipment feeding port to reduce the mixing of dust in the air into the adhesive.

　　操作規(guī)范的嚴格執(zhí)行能從流程上規(guī)避堵塞。換膠時需徹底排空管路內(nèi)的殘留膠料，避免新舊膠料混合產(chǎn)生化學反應（部分不同批次膠料可能存在成分差異），形成難以清除的硬塊。長時間停機前，需用清洗液沖洗整個打膠系統(tǒng)，確保管路、混合腔和噴嘴內(nèi)無膠料殘留，防止停機期間膠料固化堵塞。操作人員需定時巡檢設備運行狀態(tài)，觀察出膠是否順暢、膠條是否均勻，若發(fā)現(xiàn)出膠量突然減少或壓力異常升高，需立即停機檢查，避免小堵塞發(fā)展為嚴重故障。

　　The strict implementation of operational standards can avoid blockages in the process. When changing the glue, it is necessary to thoroughly drain the residual glue in the pipeline to avoid chemical reactions caused by the mixing of new and old glue (some different batches of glue may have compositional differences), which can form hard lumps that are difficult to remove. Before a prolonged shutdown, it is necessary to rinse the entire gluing system with cleaning solution to ensure that there is no residue of glue in the pipelines, mixing chambers, and nozzles, in order to prevent the glue from solidifying and blocking during the shutdown period. Operators need to regularly inspect the operation status of the equipment, observe whether the glue is smooth and whether the glue strip is uniform. If a sudden decrease in glue output or an abnormal increase in pressure is found, the machine should be stopped immediately for inspection to avoid small blockages from developing into serious faults.
