I. Daily Pre-Shift/Post-Shift Maintenance of The High Speed Automatic Packing Machine
1. Cleaning
* Machine Body and Surface: Clean the outer surface of the equipment with a soft cloth to remove dust, oil, and residual paste, keeping it clean.
* Filling Head and Nozzle: Disassemble the filling head and thoroughly clean it with a special cleaning agent (such as food-grade cleaner) to prevent paste from hardening and clogging.
* Conveyor Belt and Pallet: Clean the conveyor belt of any residue and check for adhesion or wear.
* Sensors and Photoelectric Sensors: Clean the sensing parts with alcohol wipes to ensure accurate positioning and detection.
2. Key Component Inspection
* Seal Inspection: Check the sealing rings of the filling system and pipe interfaces for aging or leakage.
* Air System: Check for air leaks in the air pipes and for water accumulation in the drain filter; drain it promptly.
* Electrical Connections: Check for loose cable connectors and ensure the emergency stop button functions properly.
II. Weekly Routine Maintenance
1. Mechanical Component Inspection
* Transmission System: Check the tension and wear of chains, belts, and gears; adjust or replace as necessary.
* Bearings and Guide Rails: Add grease and check for abnormal noise or vibration.
* Cutter and Sealing Device: Clean the cutter blade and check if the sealing temperature and pressure are normal.
2. Accuracy Calibration
Weighing System: Calibrate the electronic scale or flow meter to ensure that the filling weight error is within the allowable range.
Filling Volume Test: Perform periodic sampling weighing and adjust filling parameters.
III. Monthly In-Depth Maintenance
1. Comprehensive System Inspection
Pump and Valve System: Check the paste delivery pump and valves for wear or blockage, and clean the internal flow channels.
Control System: Check the PLC and touch screen operating status and back up parameter settings.
Safety Protection: Check the reliability of the protective cover, emergency stop device, and safety interlock function.
2. Lubrication Plan
Lubrication according to the manual: Add special grease/oil to designated parts (such as bearings, sliders, and lead screws).
Avoid Contamination: Avoid the filling area during lubrication to prevent product contamination.
IV. Seasonal/Special Maintenance
1. Environmental Adaptability
Temperature and Humidity Control: Avoid operating the equipment in excessively high humidity or temperature differences to prevent electrical components from becoming damp or the properties of the paste from changing.
Rust Prevention: Rust prevention maintenance is required for metal parts in humid environments.
2. Long-Term Inactivity Maintenance
Thorough Cleaning: Drain residual paste from pipes, clean, and air dry.
Protection of Critical Components: Disassemble easily aging parts (such as sealing rings) and store them separately; place desiccant in the electrical cabinet.
V. Maintenance Records and Training
1. Record Management
Maintenance Log: Record in detail the content of each maintenance, parts replaced, and handling of any abnormalities.
Fault Analysis: Record fault phenomena and solutions to accumulate maintenance experience.
2. Personnel Training
Operating Procedures: Train operators on correct use and basic maintenance (such as cleaning and daily inspection).
Safety Instructions: Emphasize safety procedures such as prohibiting manual adjustment and cleaning while the equipment is running.
