An adjustable opening and closing roller assembly

Abstract

The utility model relates to braiding equipment technical field relates to a kind of adjustable opening and closing roller assembly, and roller bar is divided into front roller bar and rear roller bar, and roller bar is located between adjusting assembly.The adjusting bolt is equipped between the left and right rocker arms of adjusting assembly, the adjusting bolt is through lifting adjusting plate, lifting adjusting plate is inserted in the adjusting seat outside gear box, recess is in the inside of lifting adjusting plate, adjusting bolt is through adjusting seat connection limit block in recess, can be driven adjusting bolt up and down displacement by lifting adjusting plate.Compared with prior art, beneficial effect is: the scheme is driven lifting adjusting plate, adjusting bolt moves, can drive left and right rocker arms synchronous swing, accurately adjusts the distance between front and rear roller bar, adapts different specifications yarn and braiding demand, avoids that uneven spacing leads to traction tension anomaly;While spacing error can be detected by spacing detector, it is convenient for fast calibration accuracy, ensure that the distance between each position of roller bar is consistent, reduce adjustment error.
