[0002] The computer flat knitting machine is a double needle plate latch needle weft knitting machine. Its cam device is like a set of flat cams. The pins of the knitting needles can enter the grooves of the cams and move the cams, forcing the knitting needles to make regular lifting and lowering movements in the needle grooves of the needle plate. Through the actions of the needle hooks and the needle tongues, the yarns can be woven into knitted fabrics. The knitting needles and pins are installed on the needle plate, which requires that the needle plate of the computer flat knitting machine is level as a whole. When the existing needle plate correction structure of the computer flat knitting machine is in use, the needle plate is not fixed stably enough, so that the needle plate is easy to slide when correcting the needle plate, which is not convenient to correct. At the same time, the correction rod is directly operated manually, which is easy to over-correct and affects the use of the needle plate.
