Regular inspection and maintenance
1. Routine maintenance and processing The maintenance worker needs to inspect the machine’s electric oil pump, centralized oil supply, main motor heat dissipation part, input shaft of the open cam box, electromagnetic brake, weft finder, scissors, hemming, temple support and edge catching yarn processing Perform routine maintenance. 2. Maintenance and processing when the machine is stopped. Check whether the temple ring rotates sensitively, whether it is worn, whether there is accumulation of flying debris, whether the distance between the yarn stop pin and the main drum is 0.5mm, whether the air pipe is leaking, whether the centralized oil supply is leaking, and whether the oil pipe is leaking. Check whether there is any damage or bending, whether there are flying dust accumulated inside the control box, confirm whether the height error of the heald frame is within 2mm, whether the air filter exhaust pipe is unobstructed, whether there is flying dust on the warp beam pinion, and whether there is flying dust on the bevel gear shaft of the opening device. Check whether there are yarn ends, whether the mesh on the oil filter is blocked, whether there are yarn ends rolled on the let-off and easing warp beams, whether the wire insulation sleeves are damaged, and whether the brake clearance is correct. Add oil to the oil nozzle, add oil to the tooth surface of the open gear and the chain, and check whether there is wear on the heald frame and heald frame guide plate. 3. During the half-year maintenance and treatment, it is necessary to check whether the yarn winding fork is clean, whether there are yarn marks and scratches on the main drum and pin drum, whether the inside of the yarn stop pin assembly is dirty, whether the opening wire rope is stretched or damaged, whether the return heald spring is Is there any damage? Check whether the bearing of the open wire rope connecting seat is worn. Whether the tension of each belt is appropriate and whether there is any damage, whether each sensor is working properly, whether the transmission gearbox, take-up gearbox, and let-off gearbox should be replaced with lubricating oil, remove the iron filings on the opening cam box magnet, and whether the filter mesh is Clogging, whether the reed is stained with dirt, whether the wind speed value is normal, whether the U-shaped bushing of the drop hook is worn within 2mm, whether the main nozzle duct is bent, whether the coiling roller chain is stretched, whether the planetary gear tooth gap is normal , whether the wear of the planetary bobbin seat bushing is within 0.5mm, whether the wear of the planetary bobbin shaft is within 0.5mm, whether the wear of the planetary bobbin bushing is within 0.5mm, whether the auxiliary nozzle has yarn marks or is bent, Whether there is oil in the scissor device, etc. 4. One-year maintenance and treatment. Check whether the screws of the main nozzle support are loose. The screws need to be retightened. 5. Maintenance and treatment after two years: Whether the winding roller, pressure roller and rough rubber are worn, whether the wear of the warp beam is within 0.3mm, whether the performance of the buffer is reduced, whether the nylon bushing and buffer guide Check whether the pin is worn, whether the auxiliary nozzle is dirty, whether the scissor device on the yarn supply side can cut the weft yarn correctly, whether the yarn stop pin hole of the yarn stop pin assembly is worn, whether it is within 0.5mm, and whether the yarn length of the winding roller is Wear, whether it is within 0.5mm. 6. Maintenance and treatment after three years: Check whether the solenoid valve lubricating oil is insufficient and whether the take-up roller rotates sensitively. 7. The seven-year overhaul includes the overhaul of bearings, oil seals, gears, cams, bushings, yarn stop pins, main motors, and related parts of the frame, shedding, let-off, take-up, and weft feeder.
