The special equipment winding machine is a secondary automatic constant tension winding machine for special yarns.
Special equipment winding machine function:
The constant speed transmission used in the secondary winding is a very classic control link. Using this simple control method, as the number of windings increases, the tension of the plastic sleeve wound by the yarn changes, resulting in a tight inside and outside winding of the yarn spindle, which is not conducive to the uniform penetration of the dye into the plastic sleeve in the subsequent dip dyeing process The wound yarn reduces the quality of yarn dyeing. In addition, in the weaving process after dyeing, the cloth spun out of spindles with inconsistent tightness will have uneven surface, which reduces the quality of the cloth.
Easy drive modification plan:
Easy drive electric SMART-4T0007M inverter on-site transformation plan: The process requires the winding machine to control the winding tightness with constant tension. When the pay-off spindle speed is too fast, when the winding machine's tension swing frame falls freely, frequency conversion is required at this time The tension swing frame is accelerated to allow the tension swing frame to be wound with constant tension in the middle area. When the pay-off spindle is broken, the winding machine tension swing frame freely falls to the bottom dead center position. At this time, if the tension swing frame remains at the bottom dead point After 10s, the inverter will automatically stop, so that the inverter thinks that the winding process is interrupted (yarn break). When the tension swing frame falls to the bottom dead center and it is not enough to maintain 10S, the tension swing frame is due to the pay-off spindle. Speed relationship, when the tension swing frame of the winding machine returns to the upper and lower dead center allows constant tension winding, the inverter is required to keep the current speed and continue to work; on the contrary, when the tension swing frame is slowed down by the pay-off spindle That is, when the wire is tensioned, the tension swing frame of the winding machine is required to gradually decelerate when the tension swing frame rises to the top dead center. When the tension swing frame is maintained at the top dead center for 10 seconds, the inverter is required to stop automatically at this time, and the inverter judges There is a problem with the pay-off spindle pay-off several times (yarn wrapping). When the tension swing frame cannot be maintained at the top dead center for 10 seconds and returns to the original position, the inverter is required to keep the current speed and continue to work.
Note: 10S thread breakage or winding time supports user-defined and can be adjusted arbitrarily between 0-300S.
The modification plan is fully applicable to the on-site working conditions of special equipment winding machines, and meets the requirements of on-site winding technology, improves on-site work efficiency, and is recognized by users.
