In order to improve product quality, reduce end breaks, and reduce yarn defects, spinners must not only be proficient in operating techniques, but also must be familiar with mechanical performance and be the master of the machine. In the actual production process, spinners want to combine basic operations to prevent mechanical defects, mainly considering the following aspects:
1. The bobbin feels thick and hard when pulling out the yarn. After checking, the rubber roller is not in place, the pressure fails, the rubber roller is short of oil, the roving is wound around the back roller, the roving does not pass through the bell mouth, the roving is double fed, and the traveler is too large Heavy, the spindle belt slides onto the spindle tower and so on. If the bobbin feels loose and rotten, check the spindle for lack of oil, the wire ring is too light, the roving is defective, the spindle belt is loose or slips out of the spindle plate, there is too much yarn on the spindle or in the bobbin, etc.
2. When looking for the end, you can see feathers on the inclined surface of the bobbin. Check that the steel ring is rough and floating, the wire ring is used incorrectly or is worn, the spindle is crooked, the steel plate is lifted, the yarn sliver jumps out of the collector, the cleaner fails, and the yarn is separated Rough board etc.
3. When drawing yarn, if you see uneven slubs in the drawn yarn strips, check whether the bell mouth of the drafting part is blocked or skewed, the yarn strips touch the rubber ring frame, the collector is damaged, flowers accumulate, and flying flowers are mixed inside. , yarn strips jump out of the collector, accumulation of flowers on the lower apron, cracks and deformation of the apron, flying flowers of impurities inside, deformation of the apron, jitter, no apron, jitter of the roller and defective roving, etc. The lower rubber ring is deviated, missing, damaged, deformed, the nylon plug block is installed backwards, missing, used incorrectly, the tension plate is deformed, blocked, does not fall into the groove, the rubber roller is shelled, etc.
4. When lifting the yarn, it feels tight in the hand. Check the spindle for tilt, shaking of the head, lifting and roughness of the steel ring, worn out traveler, incorrect yarn guide hook, yarn guide plate, cleaner touching the traveler, roughness on the yarn separation plate, etc. .
5. Track and inspect various broken ends during jointing. If the wire ring is found to have flowers, check the cleaner failure, etc. If the head is found to be floating, check the flute tube eye hair and channel obstruction; if the convex yarn is found, check the sheep’s foot blockage, the ring plate is knocked, etc.; if the bobbin is found, check the spindle or The bobbin is defective, there is yarn waste on the spindle, etc.; if the whole yarn is poorly formed, check the supporting head and teeth to turn over.
