Common Faults and Troubleshooting for Mother Yarn Splitting Machine During Tex Mono Split Mono Filament Production, Pure

The core conclusion: Over 60% of unstable tex issues on mother yarn splitting machine come from tension sensor drift and uneven feeding of mother yarn raw material. When tex value of mono filament fluctuates frequently during tex mono split, the first inspection target is tension sensor calibration status instead of directly replacing cutting blades. Industry maintenance data shows sensor drift accounts for 36% of all splitting machine faults, higher than mechanical wearing part failure at 25%. Sensors will generate reading deviation after long operation, and wrong tension signal leads to inconsistent splitting effect for polyester mother yarn or nylon mother yarn. Lanxiang mother yarn splitting machine reserves sensor self-check function; the system can alert operators once sensor error exceeds 3% threshold automatically. The built-in warning function reduces undetected quality drift time by 78%, avoiding large batches of unqualified mono filament in tex mono split. Another frequent fault is mono filament entanglement after splitting, mostly caused by improper winding roller alignment or static accumulation on yarn surface. Misaligned winding roller by more than 0.3 mm will pull mono filament sideways and create tangled coils, stopping continuous splitting production. When dealing with entanglement faults, operators should check roller parallelism first. Adjusting roller position solves 59% of filament entanglement problems. Insufficient air pressure on feeding rollers also causes irregular mother yarn feeding. Air pressure lower than 0.3 MPa cannot clamp yarn stably. Unstable feeding makes single section mother yarn run faster or slower, creating obvious tex difference along the length of finished mono filament. For nylon mother yarn splitting, sudden filament breaking may be related to raw material temperature. Raw yarn colder than 20℃ raises brittleness and fracture risk. Preheating nylon mother yarn to 23–27℃ before feeding reduces sudden breakage faults by 54% during tex mono split mono filament processing. Blade edge chipping leads to burr on mono filament. Blade chipping usually appears after 120–150 working hours of continuous splitting. Regular visual inspection of cutter edge every shift can find chipping early; delayed replacement will push defective rate above 4.2%. Power supply faults manifest as roller speed jumping. Voltage variation exceeding ±10% disturbs servo motor operation of mother yarn splitting machine. Installing external voltage stabilizer can limit speed fluctuation within 1.5% and protect tex mono split mono filament quality. Foreign particles mixed in mother yarn also trigger emergency stop. Hard particles scratch cutter edge and damage mono filament in splitting process. Installing simple yarn filter before feeding port intercepts over 82% of solid impurities in polyester mother yarn or nylon mother yarn. Many mills make the mistake of only repairing equipment after full breakdown. Preventive maintenance cuts unexpected shutdown events by 66%. Fixed daily, weekly and monthly inspection items help maintain stable tex mono split operation and extend service life of mother yarn splitting machine. Lubrication of transmission shaft is often overlooked. Lack of lubrication increases friction, raises vibration and accelerates cutter wear on splitting machine. Refilling lubricant every 80 working hours keeps shaft vibration amplitude below 0.02 mm and maintains consistent cutting gap.

FAQ
