Methods for the Maintenance and Servicing of Automatic Edge-Protecting Strapping Machines for Cartons
Daily Maintenance：
Cleaning the Equipment：After the operation of the equipment is completed, cut off the power supply. Use a clean wiping cloth to remove dust, paper scraps, and debris from the surface of the equipment. Pay particular attention to cleaning the edge-protecting device, strapping device, and transmission components. This helps prevent the accumulation of dust and debris from affecting the performance of the equipment.
Inspecting Components：Inspect the supply of edge-protecting materials and strapping belts to ensure an adequate supply and that there is no jamming. Meanwhile, check the connections of all components to see if they are secure. Look for any signs of looseness, wear, or damage. If any screws are found to be loose, tighten them promptly.
Regular Maintenance：
Lubrication Maintenance：At regular intervals (usually once a week or determined according to the frequency of equipment usage), apply an appropriate amount of lubricating oil to the transmission components of the equipment, such as chains, gears, and bearings. This reduces friction, minimizes wear, and ensures the smooth operation of the transmission system.
Cleaning the Sensors：Sensors are key components that control the operation of the equipment and are prone to being obscured by dust or debris, which can affect their accuracy. Regularly wipe the surface of the sensors gently with a clean soft cloth to ensure that they can accurately detect the positions of cartons and materials, thus ensuring the normal operation of the equipment.
Replacing Wearing Parts：Based on the usage condition of the equipment, regularly replace vulnerable parts, such as the cutting knife of the strapping belt, the hot-melt head, and the conveying rollers of the edge-protecting materials. These parts will experience wear after long-term use, which may affect the performance of the equipment and the quality of strapping. Timely replacement can prevent malfunctions.
Calibrating Parameters：Calibrate the parameters of the equipment on a monthly or quarterly basis, such as the tension force of the strapping belt, the conveying length of the edge-protecting materials, the hot-melt time, and temperature. Ensure the accuracy of the parameters to meet the requirements of different cartons and packaging, and maintain the stability of the packaging quality.
In-depth Maintenance：
Electrical System Inspection：Every six months or once a year, electrical technicians should conduct a comprehensive inspection of the electrical system of the equipment. This includes checking for loose wire connections, damaged electrical components, and the normal operation of the PLC program. Detect and eliminate potential electrical fault hazards in a timely manner to prevent equipment damage or accidents caused by electrical issues.
Mechanical Component Overhaul：Disassemble, inspect, and clean the main mechanical components of the equipment, such as the reduction gearbox and the motor. Check the wear condition of the gears, clean the bearings, and replace the lubricating grease to ensure the optimal performance of the mechanical components. For parts with severe wear, replace them promptly to restore the accuracy and stability of the equipment.
