EBC electronic warp let-off reversal compensation method and reversal compensation device for warp knitting machine

Abstract

The invention discloses an EBC electronic let-off reverse compensation method and reverse compensation device for a warp knitting machine. The warp knitting machine comprises a disc head wound with warp yarn and a looping mechanism for conducting looping weaving on the warp yarn, an EBC electronic let-off reverse system comprises a servo motor driving the disc head to rotate and a speed reducer, and when the servo motor rotates forwards, the warp yarn on the disc head is driven to be unwound to the looping mechanism for looping weaving. The reverse compensation method comprises the step that the length of the warp yarn between the disc head and the looping mechanism is changed by pressing the warp yarn, so that EBC electronic let-off reverse compensation is achieved. The reverse compensation device comprises a press roll and a driving mechanism, and the press roll is arranged over the warping yarn between the disc head and the looping mechanism and driven by the driving mechanism to do vertical movement and presses the warp yarn when the press roll does vertical movement. According to the reverse compensation method and device, EBC electronic let-off reverse compensation can be achieved without reverse of the servo motor, the service life of the servo motor and the speed reducer is significantly prolonged, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a let-off method and a let-off device of a warp knitting machine, in particular to an EBC electronic let-off reversal compensation method and a reversal compensation device of a warp knitting machine. Background technique [0002] The EBC electronic warp let-off reversal compensation method of the existing warp knitting machine, the warp knitting machine includes a pan head wound with warp yarns and a loop forming mechanism for knitting the warp yarns into loops, and the EBC electronic warp let-off is programmable control Multi-speed electronic warp let-off, which includes a servo motor and a reducer that drive the pan head to rotate forward and reverse. Go around to the knitting mechanism for knitting, and the servo motor realizes the EBC electronic warp let-off reversal compensation by reversing, that is to say, the warp knitting machine weaves the three-dimensional pattern with concave and convex patterns, which is frequentl...
