In high-speed continuous production, the mechanical components and electrical system of automatic folding and gluing boxes are constantly under load. Lack of timely maintenance can easily lead to decreased precision, frequent malfunctions, and even affect the quality of finished products. Establishing a scientific daily care process can ensure stable equipment operation, extend its service life, and reduce unplanned downtime losses.
I. Pre-shift Inspection and Preheating Before starting the machine each day, check whether the power supply voltage is stable and whether the three phases are balanced; confirm that the air pressure meets the equipment requirements (generally 0.5MPa~0.7MPa, example data) and that there are no leaks in the pipelines. Observe whether the grease at each lubrication point is sufficient; guide rails, bearings, gearboxes, etc., need to be lubricated with oil or grease as specified. Preheat the glue coating system to ensure that the hot melt adhesive reaches the appropriate viscosity, avoiding uneven coating or glue separation due to insufficient temperature.
II. Monitoring and Cleaning During Operation During production, pay attention to any abnormal operating sounds and vibrations of the equipment. If any abnormal noises or vibrations are found, stop the machine immediately for investigation. Cardboard scraps, paper dust, and excess glue tend to adhere to the creasing roller, folding arm, and sensors. Regular cleaning with a soft brush or non-woven cloth is necessary to prevent signal misinterpretation or operational malfunctions. Visually inspect the glue applicator and scraper to remove dried glue residue and maintain a uniform and neat glue line.
III. Post-Shift Maintenance and Component Reset After work, turn off the heating system and wait for the glue temperature to drop to a safe range before disconnecting power. Clean residual cardboard and dust from the conveyor belt and paper receiving platform. Wipe the machine casing and control panel to prevent oil and paper scraps from accumulating and affecting heat dissipation and operation. Reset movable parts such as folding arms and pressure plates to their initial positions to avoid deformation due to prolonged stress. For equipment that will be out of service for an extended period, apply rust-preventive oil to the friction surfaces and cover with a dust cover.
IV. Regular Deep Maintenance In addition to routine maintenance, critical components should be disassembled and inspected weekly or monthly according to the maintenance plan: such as the wear of the creasing roller, the clearance of the folding arm joints, the tension of the drive belt, and the condition of the motor carbon brushes. Replace aged or damaged seals and filters. Check the tightness of electrical wiring terminals to prevent loosening that could lead to unstable signals or overheating. Retest the accuracy of the servo system and encoder to ensure accurate positioning.
V. Consumables and Spare Parts Management Hot melt adhesive, lubricating oil, belts, and other consumables should be replaced periodically according to usage time and manufacturer recommendations to avoid affecting process quality due to expiration or deterioration. Commonly used wear parts such as folding modules, nozzles, and sensors should be kept in stock to shorten the fault repair cycle.
VI. Personnel Training and Records Operators should be familiar with the maintenance content and procedures, able to identify common abnormalities and take initial measures. The maintenance process must be recorded, including time, items, replaced parts, and problems found, to facilitate traceability and trend analysis, and continuous optimization of maintenance plans.
In summary, the daily maintenance of the automatic folding and gluing machine covers six aspects: pre-shift inspection, running cleaning, post-shift maintenance, regular maintenance, consumables management, and personnel training. Adhering to meticulous and standardized maintenance can maintain equipment accuracy and efficiency, reduce unexpected failures, and provide strong support for continuous and efficient production.
