Maintenance and management of sword heads
1. Maintenance and upkeep of sword heads (1) The sword heads and sword belts must be taken out from the loom when disembarking, and should be kept properly and have the machine maintenance worker in charge of the machine inspect the sword heads and sword belts for wear and tear and perform maintenance. . (2) When putting the machine on the machine, the maintenance worker must inspect each sword head, remove the stains, remove the tired spring blades, the bottom plate that has exceeded the wear limit and the small parts that are about to be damaged, and then install the same new parts. (3) For rapier heads that cannot be refurbished, they must be returned to the warehouse and the return time must be noted to understand the service life of the rapier heads and use them as parts for future disassembly. (4) When the new sword leader is used, the user and the time of collection must be noted on the collection account. (5) The sword head should be placed in a fixed packaging box and should not be placed in a humid place. (6) A maintenance cycle of 15 days is generally specified. Recheck the wear of the rapier head and the wear of the weft yarn release plate, and use 800-grit sandpaper to polish the surface in contact with the warp yarns. Check the clamping force of the rapier head every 45 days, check whether the weft transfer is normal, all sharp edges of the rapier head and sword belt should be rounded, and there should be no scraping on the surface. (7) It is generally stipulated that every 300 working hours, a thin layer of oil film needs to be applied to the sliding and rotating working surfaces (such as yarn clamping rods, springs, pins, screws, etc.) and contact surfaces of the rapier head with lubricating oil to keep opening and closing. Make the lubricant evenly distributed, then remove excess lubricant. If it is a warp that easily accumulates dust, the maintenance cycle can be reduced. 2. Management of rapier heads 1. Incoming factory inspection: Adopt random inspection or all inspection methods and conduct the following inspections. If you find that the standards are not met, you should contact the manufacturer and re-inspect after repairing. (1) The delivered rapier heads must be packed in cartons (or foam boxes, plastic tubes). The outer packaging should be strong and reliable to avoid damage during transportation. The model, manufacturer’s name or trademark should be marked on the inner packaging. There should be a product certificate and the year, month and day of manufacture in the box. (2) According to the model, specification, and quantity indicated on the packing list (delivery note) in the packaging box, check and conduct spot checks or complete quality inspections. The quality inspection is based on the acceptance standards, including visual inspection of the appearance, the feel of the spinning yarn to see if it is completely smooth, whether there is yarn hooking on the back of the rapier head, whether the opener and closing device are sensitive, the flatness of the rapier head, etc. 2. Warehouse management (1) The rapier head should be placed in a ventilated and dry place after storage. (2) Rapier heads of different varieties and specifications should be placed in separate factories to avoid confusion. (3) When distributing and using, it should be put into storage first and released for use to avoid excessive storage time. (4) Conduct regular inspections. It is best to apply anti-rust oil to the metal rapier head regularly to avoid rust, corrosion and damage.
