Reasons and prevention of common defects in quilt production lines Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Prevention methods: strengthen the patrol inspection of the quilt production line, appropriately reduce the bell mouth, take off the frame, master the active barrel change, prevent the head from overlapping, carefully implement the winding joint operation method, and strengthen the mechanical inspection.
2. The main reasons for the production of fine sliver are the failure of the self-stop device system, the lack of food for the inhaled sliver, the saving of wool sliver, and the short wrapping head of the sliver. The preventive management method is to strengthen the quilt production line tour teachers to understand the maintenance in time, and earnestly implement the wrapping operation method. 3. When the slub sliver is brought to sleep, the roller scale, the bending roller beats the leather, the quilt shells the line hose or surface defects, the driving wheel is not properly worn, the missing needle is worn, the thread is broken, or the pressure gauge roller bracket moves s no work flower oil, bad 3 suction effect.
The preventive method is to change the top roller and check the skin roller beating, if beat the pull bend, notify the maintenance, strengthen the inspection of machinery and wool, if no defect is found, repair it immediately, in the case of the top roller, the traditional roller should not be able to tear the defective product Well, find the bell, collect bad, replace it immediately, don't get oil, clean the work of the fly case. 4. The reasons for the production of sliver are that the construction of the drawing frame channel is not complete, the sliver opening and inner wall surface are rough, the capacity of the plum sliver barrel is too large, the aperture of the bell mouth changes too much, the collector opening is too wide, and the temperature and humidity in the workshop are carried out. The requirement is too low and high cotton sliver. The preventive method is to improve the quality of enterprise maintenance services. If a channel is found to be dirty, it can be repaired immediately; if the barrels, bell mouths, and cotton imm are unqualified, they should be adjusted immediately to improve the temperature and humidity of the production workshop environment. Leathers are not allowed to use high tampons. 5. The oily brocade strips cause useful oily hands. When the dirty hand joints are pulled, the part of the contamination after the car is pulled is not wiped clean. Feed the strips of oil.
Prevention is to strengthen inspection with clean hand joint E, rub oil at any time, and strengthen inspection of defects in advance. 6. The sliver is uneven, the reason is that the uniform roller, the winding roller, the consumer sliver meter, the roller head is too small, the top roller is skewed, jittering, the gauge gap of the pressurized front wheel is loose end difference from the bonding failure, wear and tear Clear, or defects with elastic pins are incomplete, loose rollers, the prevention method is in the shell roller system, the gold leather rollers are pulled to eliminate the bars in the bamboo cage, and the built-in inspection is the negative table removable s to strengthen the inspection, exchange At any time, intensify the maintenance, and the problem is found immediately after the repair.
