This invention discloses a
fully automated system and method for preparing weft-knitted fabrics for
dyeing and finishing, comprising a take-up device, a
yarn separating device, and a
fully automated airflow locking device. The take-up device includes a take-up lever, a
yarn hook, a first
linear drive mechanism, a first rotary drive mechanism, an outer conical sealing
nozzle, a first negative pressure suction
pipe, a second
linear drive mechanism, an inner conical sealing
nozzle, and a first shearing mechanism. The
yarn separating device includes a yarn separating rod, a second rotary drive structure, a third
linear drive mechanism, a waste yarn collection box, a negative pressure suction
nozzle, a second shearing mechanism, and a fourth linear drive mechanism. The
fully automated airflow locking device includes a negative pressure suction gun, a fifth linear drive mechanism, a
stepper motor, a forming
cam, a joint clamping mechanism, a third shearing mechanism, and a sixth linear drive mechanism. The fully automated
system and method for preparing weft-knitted fabrics for
dyeing and finishing of this invention can adapt to various batch numbers of DTY / FDY roll-packaged weft-knitted fabrics for
dyeing and finishing, achieving fully automated preparation.
