If a failure occurs in the glue output process, it\u2019s essential to scientifically troubleshoot and quickly identify the root cause. The following is a detailed troubleshooting guide to help you swiftly locate and resolve bottom glue supply issues.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>1. Check the Automatic Glue Supply Switch<\/strong><br>When the bottom glue fails to dispense, the first step is to confirm whether the automatic glue supply switch is turned on. In some cases, due to incorrect operation or system reset, the switch may be off. Enter the control interface to check the I\/O status and ensure the glue supply function is activated. If the switch is working but the problem persists, proceed to inspect other potential causes.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>2. Calibrate the Glue Level Detection Photoelectric Sensor<\/strong><br>Misalignment of the photoelectric sensor for glue level detection is another common cause of glue supply failure. If the sensor is not properly aligned with the reference line of the glue tank, it may incorrectly detect the glue level and interrupt the supply process. Re-adjust the sensor position according to the equipment manual and test its sensitivity through simulated operation. Regular maintenance should include checking sensor alignment to prevent sudden failures during production.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>3. Inspect the Photoelectric Signal Transmission Line<\/strong><br>If the sensor is correctly positioned but the signal fails to reach the PLC system, inspect the wiring. Loose connections, oxidized terminals, or damaged cables can all disrupt signal transmission. Use a multimeter to check for continuity, clean the terminals, and secure the connectors. For complex wiring systems, conduct sectional testing to locate faults quickly and ensure stable signal transmission.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>4. Replace Faulty Photoelectric Sensors<\/strong><br>If the above steps do not resolve the issue, the photoelectric sensor may be defective. Long-term use or environmental factors such as dust and humidity can cause sensor aging and failure. Replace the sensor with the same model and recalibrate the parameters after installation. Ruizhi Machinery recommends keeping commonly used spare parts in stock to minimize downtime and maintain production efficiency.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>5. Clear Glue Hose Blockage<\/strong><br>If the automatic glue supply is functioning but the glue still does not dispense, a clogged glue hose may be the culprit. Prolonged use or residual glue can cause internal blockages that hinder glue flow. Disassemble the hose and clean it thoroughly with a specialized cleaning solution, or replace it with a new one. Regular maintenance of the glue hose is an effective way to prevent such issues.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>6. Inspect the Pneumatic Control Valve<\/strong><br>As a key component in glue delivery, a clogged or damaged pneumatic valve can directly halt glue output. Disassemble the valve to check for glue residue and clean it with compressed air or solvents. If cleaning doesn\u2019t restore functionality, replace the valve. Preventive inspection of pneumatic valves during routine maintenance is strongly recommended.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><strong>7.
