I. Neatness
Maintaining a neat working environment is the foundation for ensuring the stable operation of nonwoven fabric equipment and improving production efficiency. It helps to avoid confusion caused by scattered materials and tools, and reduces the risk of equipment failure and safety accidents.
1. Raw materials and semi-finished materials on the production site shall be stacked neatly according to categories, specifications and production batches. They should be placed on designated pallets or shelves, with clear labels attached to facilitate quick access and inventory management. At the same time, a safe distance shall be maintained between the stacked materials and the equipment to ensure unobstructed operation space and emergency channels.
2. Repair tools, measuring instruments and loose parts shall be sorted and stored neatly in special toolboxes or storage cabinets. Each tool and part should have a fixed placement position, and the toolbox should be kept closed when not in use to prevent dust pollution and loss. Regular inspection and sorting of toolboxes shall be carried out to ensure that tools are intact and parts are complete.
3. Spare parts shall be stored in a clean, dry and well-ventilated designated warehouse or storage area. According to the material and storage requirements of spare parts, appropriate anti-rust measures shall be taken, such as applying anti-rust oil, wrapping anti-rust paper or placing desiccants. Spare parts shall be stacked neatly by type and specification, with obvious labels indicating the part name, model, quantity and storage date, so as to ensure timely retrieval when equipment maintenance is needed.
II. Cleanliness
Keeping the equipment and working area clean is an important measure to prevent equipment wear, corrosion and precision reduction. It can effectively extend the service life of the equipment and ensure the quality of nonwoven products.
1. Before starting the machine every day, the operator must carefully check the products and production line components to ensure that there is no debris, dust, oil stains or other foreign matters on the conveyor belt, roller, die head and other key parts. For the residual materials on the production line, special tools should be used to clean them up to avoid affecting the normal operation of the equipment and the quality of the produced products.
2. The work area should be cleaned regularly, including the ground, walls, equipment surrounding areas and storage areas. The ground should be free of debris, oil stains and water stains, and can be cleaned with appropriate cleaning agents and tools according to the degree of pollution. Waste materials and garbage should be classified and disposed of in time to keep the working environment tidy and hygienic.
3. The surface of the equipment should be wiped regularly with a clean cloth to remove dust and oil stains. Special attention should be paid to the dead corners of the equipment that are not easy to clean to prevent the accumulation of dirt. The electrical control device, including the control cabinet, operation panel and connecting wires, should be kept clean and intact. Do not use water or volatile solvents to clean electrical components to avoid short circuit or damage. Regularly check whether the shell of the electrical control device is intact and whether there is dust accumulation inside, and clean it with a hair dryer or brush if necessary.
III. Lubrication
Reasonable and timely lubrication can reduce the friction between the moving parts of the equipment, reduce wear, prevent overheating and abnormal noise, and ensure the flexible operation of the equipment. The lubrication work must follow the equipment operation manual and relevant technical specifications.
1. Regularly check the lubrication status of the chains, sprockets and other transmission parts of the equipment. Observe whether the lubricating oil on the chain is sufficient and whether it is contaminated. If the lubricating oil is insufficient or deteriorated, add or replace the specified type of lubricating oil in time. When adding lubricating oil, it should be evenly applied to each part of the chain to ensure that the chain is fully lubricated during operation.
2. The main bearings of the equipment are key components that bear load and ensure rotation accuracy. It is necessary to regularly check whether the main bearings are well lubricated, and observe whether there is abnormal phenomena such as high temperature, vibration and abnormal noise during operation. If the bearing temperature exceeds the normal range or there is abnormal noise, the machine should be stopped immediately for inspection, and the lubricating oil should be replaced or the bearing should be maintained and replaced according to the situation.
3. For the centralized oil supply system of the equipment, regularly check the oil level of the oil tank, the working status of the oil pump, and whether there is oil leakage at the oil pipes, joints and other parts. If oil leakage is found, timely repair or replace the damaged seals and pipes. At the same time, regularly filter and replace the lubricating oil in the centralized oil supply system to ensure the cleanliness and performance of the lubricating oil.
IV. Safety
Safety is the top priority of equipment operation and maintenance. Strict implementation of safety operation procedures and regular safety inspections can effectively prevent safety accidents and ensure the personal safety of operators and the safe operation of equipment.
1. During the operation of the production line, the operator should always pay attention to the running state of the equipment. If abnormal noise, vibration, odor or other abnormal phenomena are found, the machine should be stopped immediately, the power supply should be cut off, and the fault should be reported to the maintenance personnel for inspection and treatment. It is strictly prohibited to continue operation or disassemble the equipment without authorization to avoid expanding the fault or causing safety accidents.
2. Regularly inspect all belts and timing belts of the equipment, including whether the belt tension is appropriate, whether there is wear, cracking, deformation or deviation. If the belt is loose, adjust it in time; if the belt is severely worn or damaged, replace it with a new belt of the same model immediately. At the same time, check the pulley and timing wheel to ensure that they are intact and free of eccentricity, so as to ensure the normal transmission of the belt.
3. Regularly inspect the working status of electrical components in the control cabinet and on the operation panel, such as contactors, relays, fuses, buttons and indicators, to ensure that they are in good contact, sensitive in action and clear in indication. Check all motors and reducers for abnormal noise, overheating, oil leakage and other phenomena, and check the insulation performance of the motor to prevent electric leakage. For electrical components with faults, repair or replace them in time to ensure the safe and stable operation of the electrical system of the equipment.
V. Regular Inspection and Maintenance Plan
In addition to daily maintenance work, a sound regular inspection and maintenance plan should be formulated according to the use frequency, working environment and technical requirements of the equipment, so as to realize the preventive maintenance of the equipment.
1. Daily inspection: Completed by the operator before starting the machine and during operation, mainly including checking the neatness, cleanliness, lubrication status and safety performance of the equipment, and recording the inspection results.
2. Weekly maintenance: Completed by maintenance personnel and operators together, including comprehensively cleaning the equipment, checking the wear status of key parts, replacing deteriorated lubricating oil, adjusting the tension of belts and chains, and tightening loose fasteners.
3. Monthly maintenance: Conduct in-depth inspection and maintenance of the equipment, including disassembling and cleaning key components such as bearings and gears, inspecting the wear of the die head and roller, calibrating the precision of the equipment, and comprehensively inspecting the electrical system and hydraulic system.
4. Annual maintenance: Conduct a comprehensive overhaul of the equipment, including replacing worn parts that are close to the service life, overhauling the main engine and auxiliary equipment, testing the performance of the equipment, and ensuring that the equipment is in good technical condition.
VI. Notes for Maintenance
1. When carrying out equipment maintenance, the power supply must be cut off first, and a warning sign of "under maintenance, no power on" should be hung to prevent misoperation by others.
2. Maintenance personnel must be familiar with the structure, working principle and operation procedures of the equipment, and use professional tools and materials for maintenance.
3. All maintenance work should be recorded in detail, including maintenance time, content, replaced parts, fault phenomena and handling results, so as to facilitate subsequent traceability and summary.
4. The storage of lubricating oil, cleaning agents and other maintenance materials should comply with safety regulations, be stored separately from flammable and explosive materials, and be kept away from fire sources.
