Modern weaving machinery speed and precision are on the maintenance and upkeep of a higher requirement, for routine maintenance and repair machinery must insist on daily production, the machine well maintained, can play a greater potential machine to win greater economic benefits.
4.1 Day Care
(1) Clear class plush cotton attached to the creel and machine surfaces. Kept clean braid member and the winding device.
(2) class inspection and safety devices from the stop, if anomalies immediately overhaul or replacement.
(3) Check the positive yarn feeding device class, if an exception immediately removed the repair or replacement.
(4) class to check the oil level Daya disk mirror and injection machine oil pipe.
4.2 weeks maintenance
(1) Clean the yarn feed speed aluminum plate, removing the tray accumulated batt. Check conveyor belt tension is normal.
(2) Check the transmission belt tension is normal and drive smoothly.
(3) Check the rolling machine functioning.
4.3 months warranty
(1) the upper and lower triangular base plate removed, remove the accumulation of cotton.
(2) Cleaning Dust fans and hair to check whether correct.
(3) Clean the inside of batting all electrical accessories.
(4) review the performance of all electrical accessories (including automatic stop systems, security alarm systems, detection systems).
4.4 months maintenance
(1) washing machine. The upper and lower needle plate, including needles and sinkers thoroughly cleaned, pick all the needles and sinkers, if damaged, replace it immediately.
(2) Clean the injection machine and check the oil is smooth.
(3) Clean and inspect the active reservoir-type yarn.
(4) cotton and grease cleaning motor and transmission within.
(5) Check the oil collection passage is smooth.
4.5 braided main pieces of Maintenance
Woven components are located in the heart of the knitting machine, it has a direct impact on the good quality .. so woven fabric component maintenance and repair is very important.
(1) Clean the needle groove, can stain material with the needle into the knitted fabric, cleaning method: the yarn into a low-grade or waste yarn, start high-speed operation, and injected a large amount of oil in the syringe at the needle while running side Come on, so entirely out of waste oil outside of the tank so far.
(2) Check the cylinder needles and sinkers for damage, damage should be replaced immediately; in case of poor quality fabric, you should consider whether all updates.
(3) Check whether the syringe with the needle groove width distance (see the weaving surface is a straight stripes), whether the needle groove wall defects occur, such as found in the above problem, immediately renovated or updated.
(4) Check the wear Triangle, and confirm the installation location is correct, the screws are tight.
(5) Check and correct installation position of each yarn feeder, and if found to wear, should be replaced.
(6) Calibration of each installation location yarn feeding port narrowing triangle, each coil length so that the weaver's uniform with each other.
4.6 machine lubrication, oil and lubrication execution
(1) Lubrication and Oil
Daya mirror disk oil level should be checked daily, if the oil level is lower than 2/3, to manually refuel # 140 -. 160 # oil in half a year maintenance, such as oil stains found in sediments, should be replaced immediately tripod transmission Gear should be checked once a month, add grease. using the 4th bentonite grease (commonly known as snow oil). In half a year for maintenance, inspection throughout the drive bearing, add grease. with high temperature grease. All parts knit (including Sprayer grease) lubrication must be high-speed circular knitting machine for needle oil, or circular knitting machinery special lubricant.
(2) Lubrication execution
Indeed mastered the various parts of oil type, lubrication time, so that every part of the whole plant designated each machine can be obtained within a specified period of time and the amount of lubricating specified class.
Maintenance 4.7 Distribution System
Distribution system is the power source of the knitting machine, it must be implemented rigorous and regular maintenance, in order to avoid unnecessary trouble.
(1) Check whether the machine drain
(2) Check whether the switch button failure phenomenon
(3) Always check the entire detector is safe and effective
(4) Check the line for wear and breakage situation.
Internal (5) Check the motor, all parts clean and dirt adhering to the bearing fuel.
4.8 Shutdown storage Precautions
Six months in accordance with maintenance procedures on machine maintenance and repair, adding oil in a braid member; adding oil in the knitting needles and sinkers, and finally soaked in oil over the linoleum with a needle machine cover, sealed in dry and clean place.
Storage accessories and spare parts 4.9 machine.
Commonly used, the normal reserve of wearing parts is an important guarantee continuity of production, the general storage environment should be cool, dry place and temperature difference, specific storage method is as follows:
(1) cylinder and dial the reservoir first clean syringes, put oil and oil cloth, placed in wooden boxes, in order to avoid bumps, deformation prior to use of compressed air to remove the oil inside the barrel, adding the use of needle oil.
(2) triangle triangle classification of the storage reservoir, with a storage box and add the needle oil anti .
(3) knitting needles and storage of new needles and sinkers sinker should be placed on the original packing box Do not remove the seal. Old needle and sinker must cleaning, checking, pick corrupted, classification stored in the box, Add to needle oil anti
Note: All weaving components (including knitting needles, sinkers, triangle and syringes), requiring only clean it with a knitting oil, so as not to affect the normal performance of the machine to other parts of spray lubrication system circular knitting machines must be provided. clean and dry moisture-free compressed air, so air compressor dehumidifier should be impermeable. Meanwhile, high pressure air duct should ensure that output does not contain dirt debris. Parts storage time should not be too long, should be checked regularly. 4.10 woven production of common problems
(1) hole (ie, holes)
The main was caused by roving
Poor quality or too dry yarn cause
Winding the yarn tension is too large or too much tension
When a delineation
Into the ring too long, woven depopulation
(2) does not drain pin yarn feed nozzle position ---------- ---------- ---------- knitting yarn tension is too small - --------- yarn through the yarn incorrect mouth hole
(3) Set a large circle phenomenon ---------- small winding tension fabric density ---------- ---------- sinker end position fully launched, ---------- not lead to unseating the needles tongue damage
(4) the yarn ---------- damage the tongue tip position is too high or too ago, the Queen Mother, also pay attention to whether the tongue into the mouth of the yarn thread guide hole
(5) the lack of oil or a poor striker heel ---------- ---------- improper use oil or yarn quality from inappropriate use of the knitting yarn ----- ----- vehicle speed is too high or fabric density is too high when a delineation ---------- ---------- damage caused by the syringe, the needle plate or triangle --- ------- woven components are not smooth, clean inadequate
(6) The sinker damage ---------- ---------- starvation or improper use of clean oil shortage sinker Triangulum ---------- feed Yarn or nozzle gap encountered ---------- sinkers sinker and sinker triangle between the right, normal should be 0.25-0.3-mm.
