Bilateral mesh control method of full-automatic computerized flat knitting machine

Abstract

The invention discloses a bilateral mesh control method of a full-automatic computerized flat knitting machine. The mesh change target position requirement of woven clothes is set to be that for the same row of the woven clothes, the mesh value of the positions of two sides of the row and the woven sections at least one needle away from the two sides is reduced by at least 2 character codes relative to the preset mesh value of the row of the woven clothes, and the mesh change target position requirement of the woven clothes is pre-input into a machine head main MCU control chip; a mesh motor driving chip is used for outputting a mesh motor motion curve according to a driving signal, the double-side mesh value of the woven clothes is reduced in the movement process of the machine head, so as to eliminate the problem that the double sides of the woven clothes are elongated; meanwhile, the control current of a mesh motor is calculated and determined according to a reference voltage PWM signal output by the machine head main MCU control chip; and according to the bilateral mesh control method of the full-automatic computerized flat knitting machine, the problem that the two sides of the woven clothes are lengthened due to a roller traction effect of the computerized flat knitting machine can be reliably eliminated by reducing the mesh value of the two sides of the woven clothes.

Description

technical field [0001] The invention relates to a control technology of a fully automatic computerized flat knitting machine, in particular to a bilateral stitch control method of a fully automatic computerized flat knitting machine. Background technique [0002] The working principle of the fully automatic computerized flat knitting machine is a mechanical device that automatically weaves clothes by designing pattern files through control software. [0003] During the knitting process of the automatic computerized flat knitting machine, rollers are needed to pull the knitted clothes. However, since the rollers are always pulling and the knitting yarn rotates at both sides of the knitted clothes, this will cause the two sides of the knitted clothes to be slightly longer than the middle , this problem is also a problem that has been difficult to solve in the traditional automatic computerized flat knitting machine control. The current solutions to this problem basically alle...

Problems solved by technology

[0003] During the knitting process of the automatic computerized flat knitting machine, rollers are needed to pull the knitted clothes. However, since the rollers are always pulling and the knitting yarn rotates at both sides of the knitted clothes, this will cause the two sides of the knitted clothes to be slightly longer than the middle , this problem is also a problem that has been difficult to solve in the traditional automatic computerized flat knitting machine control

The current solutions to this problem are basically to alleviate the problem by reducing the knitting speed and adjusting the yarn tension, which not only makes the control process complicated, but more importantly, this method cannot effectively prevent the occurrence of the problem
