The maintenance of high-speed jacquard machines needs to be systematically carried out from five aspects: daily lubrication, regular inspection, key component maintenance, deep cleaning, and equipment status management. The specific methods are as follows:
1. Daily lubrication management
Basic lubrication
Daily operation: Before starting up, lubricate the core components such as the rotor, axis, and runner, and wipe the table clean to avoid foreign objects getting stuck.
New equipment running in: After 600 hours of operation, the new machine needs to be forced to change the oil.
. The oil drain screw is located at the bottom of the lower plate. After draining the old oil, rinse the oil injection hole with diesel, and then add heat-resistant engine oil to the upper plate until the mark is reached.Bearings and chains: Lubricating grease should be added to the bearings every month, and it is recommended to use engine oil for the transmission chain. Before adding oil, old oil stains should be cleaned.
.Lubrication of special components
Needle maintenance: The needle should be sprayed with oil every half month (which can be shortened to once a week in rainy season), and it is recommended to use transformer oil to maintain a moderate oil level.
.Controller needle rollers: Check the lubrication status of the needle rollers on the lifting plate control lever every month and replenish lubricating grease.
.2. Regular Inspection and Adjustment
Oil Level and Cleanliness
Gear Oil Inspection: Check the gear oil level in the base box every month to ensure it is in the center of the two scales on the oil gauge.
. If it is below the lower limit, refueling is required, but it should not be excessive to avoid oil leakage.Electrical cleaning: Keep the electrical box clean to prevent dust accumulation from causing short circuits or overheating.
.Transmission system calibration
Chain/belt tension: Regularly check the tension of the chain or belt. If it is too loose, it will cause slipping, and if it is too tight, it will accelerate wear.
. Adjust to the appropriate state according to the equipment manual.Alignment: Check the alignment of the coupling, drive machine, and pump to ensure smooth transmission.
.III. Deep maintenance of key components
Knife holder and vertical needle
Blade wear: Long term cooperation between the needle lifting blade and the vertical needle can easily produce grooves. Check every 6 months and replace the blade if necessary.
.Pressure grid adjustment: When installing the pressure grid, it is necessary to maintain a distance of 1mm between the legs of the vertical needle and ensure that the grid body is slightly tilted to avoid the horizontal needle from breaking.
.Lift plate controller
Wear detection: After several years of operation, if the height position of the push pin inside the lift plate is not consistent with the working surface of the pressure grid, it indicates that the lift plate is severely worn and needs to be flipped 180 ° to use another working surface or replaced directly.
.Horizontal needle and guide plate
Horizontal needle replacement: When replacing the horizontal needle, first remove the connecting plate and safety needle, and carefully remove the broken horizontal needle.
. If necessary, remove the hole selection needle box and accurately insert new needles into the dense gaps between vertical and horizontal needles.Guide plate inspection: The brass guide plate of the horizontal needle should be checked for wear once a year and replaced if necessary.
.Fourth, deep cleaning and dust prevention
Mechanical structure cleaning
Disk and guide rail: Clean the broken wires, guide rails, and other rotating parts on the disk in a timely manner, and keep the lubrication channel unobstructed.
. Gap cleaning: Use an air pump to thoroughly clean the gap between the upright needle, the gap between the yellow wire sleeve and the pulley rope angle iron, the gap between the copper plate and the needle guard plate every month, to prevent dust accumulation from affecting the accuracy of movement. Electronic component protectionAir filtration: Some high-speed jacquard machines are equipped with an air filtration system, and the filter screen is regularly cleaned to prevent foreign objects such as lint from entering the machine.
.Electrical cabinet heat dissipation: Check whether the cooling fan in the electrical cabinet is working properly, whether the air duct filter is blocked, and promptly clean the attached dust.
.Fifth, Equipment Status Monitoring and Management
Fault Analysis
Regular Testing: Establish a testing team composed of equipment responsible persons and technical personnel to analyze equipment fault status and develop handling plans.
.Patrol inspection: Strengthen equipment integrity inspection, focus on repairing vulnerable parts, and assign responsibilities to individuals.
.Maintenance strategy optimization
Conservative treatment: Cleaning and maintaining faulty components costs about one-third of replacing them, but cannot guarantee complete disappearance of the fault, suitable for short-term emergency situations.
.Thoroughly replace: replace the core components (such as the moving iron hook, controller, etc.) as a whole to ensure that the equipment can be used normally for more than 3 years and is suitable for long-term stable production.
