What is the daily maintenance frequency of the straight intersection?

The frequency of daily maintenance of straight intersection belt will be different due to the use intensity of equipment, working environment and other factors.

I. Daily maintenance (after work)

observational check

At the end of each day's work, the overall appearance of the straight crossing belt should be checked. Check whether there is obvious damage on the surface of the conveyor belt, such as laceration, tearing and wear. For example, if you find a small scratch on the surface of the conveyor belt, you can mark it in time and observe its development; If the scratch is deep, it may need to be repaired immediately to avoid the breakage of the conveyor belt caused by the expansion of the scratch.

Check whether there is material accumulation on the surface of each roller (driving roller, reversing roller, etc.) and idler. Material accumulation may affect the rotation of rollers and idlers and increase the running resistance of equipment. At the same time, check whether there are signs of looseness or deformation of the supports of the rollers and idlers.

Cleaning work

Cleaning the conveyor belt is an important part of daily maintenance. Use special cleaning tools to remove dust, paper scraps, tape residues and other debris on the conveyor belt. If sundries are attached to the conveyor belt for a long time, they may enter the equipment and damage the mechanical parts, and may also affect the friction of the conveyor belt, resulting in slippage when conveying articles.

Clean up the dust and sundries in the equipment frame and surrounding area, and keep the equipment clean and tidy. Excessive dust may affect the performance of electrical components, such as the sensitivity of sensors.

Lubrication inspection

For parts requiring lubrication, such as the bearing of the drum and the chain (if any), check whether the lubricating grease is enough. If insufficient lubricating grease is found, it should be added in time. Proper lubrication can reduce the friction between components, reduce wear and prolong the service life of equipment.

Second, weekly maintenance (at least once a week)

Fastening inspection

Check whether all bolts, nuts and other fasteners on the equipment are loose. Focus on checking the frame connecting bolts, fixing bolts of rollers and idlers, etc. Use a torque wrench to check and tighten according to the specified torque value, and the torque value error of connecting bolts of general equipment should be controlled within 10%.

Tension inspection of conveyor belt

Check whether the tension of the conveyor belt is appropriate. It can be judged by lifting the height of the conveyor belt with your fingers at the contact point between the conveyor belt and the driving roller. If the conveyor belt is too loose, it may slip; If it is too tight, it will increase the wear of the conveyor belt and various components. Under normal circumstances, fingers can gently lift the conveyor belt for 10-15mm.

Electrical system inspection

Check the electrical components in the electrical control cabinet for overheating, discoloration and other abnormal phenomena. Check whether the wire connection is firm, damaged or aging. Use an insulation resistance meter to check the insulation resistance of the motor and other equipment. Generally, the insulation resistance of the motor should be not less than 0.5MΩ. At the same time, check whether each sensor (such as photoelectric sensor, proximity sensor, etc.) works normally, and clean the dust and stains on the sensor surface to ensure its detection accuracy.

Three, monthly maintenance (at least once a month)

Component wear inspection

Check the easily worn parts such as rollers, idlers and chains (if any) in detail. Measure the outer diameters of rollers and idlers, compare the original dimensions and calculate the degree of wear. Generally speaking, if the outer diameter of the roller or idler wears more than 5% of the original diameter, it should be replaced. For the chain, check the wear of the links. When the elongation of the links exceeds 3%, it may be necessary to replace the chain.

Inspection of conveyor belt joint

Carefully check the joint part of the conveyor belt to see if the joint is open (for vulcanized joints) or loose (for mechanical joints). If there is a problem with the connector, it should be repaired or replaced in time. For example, a special glue can be used to repair the glue-opened part of the vulcanized joint, and then vulcanized.

Inspection of reducer and motor

Check the oil level and oil quality in the reducer. The oil level should be within the specified range of the oil window. If the oil quality becomes turbid, smelly or contains metal particles, it should be replaced in time. Generally, the first oil change time of a reducer is after 500-1000 hours of operation, and then every 3000-5000 hours of operation.

Check the heat dissipation of the motor and clean the dust and sundries on the heat sink of the motor. At the same time, use a vibration measuring instrument to check the vibration of the motor. Generally, the effective value of the vibration speed of the motor should not exceed 2.8 mm/s.. If the vibration of the motor is too large, it may be caused by the damage of the internal bearing of the motor, which needs further inspection and maintenance.
