Description

Technical Field

[0001] The utility model relates to the technical field of knitting machine accessories, in particular to an anti-scratch yarn needle plate of a knitting machine. Background Art

[0002] The knitting machine is a double-needle plate latch needle weft knitting loom. Its cam device is like a set of flat cams. The needle feet of the knitting needle can enter the groove of the cam, move the cam, and force the knitting needle to make regular up and down movements in the needle groove of the needle plate. Through the action of the needle hook and the needle tongue, the yarn can be knitted into a knitted fabric. During the rise of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle tongue, and withdraws the needle tongue to hang on the needle bar; during the descent of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend into a coil, while the original coil is removed from the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting needles are connected to each other to form a knitted fabric.

[0003] When the knitting machine is working, the needles and inserts need to move repeatedly at high speed between the two inserts, which will cause the needles and inserts to rub against the inserts excessively, thus causing the inserts to deform and cause the thread to wear. In addition, the needle plate will receive a certain vibration force when moving, which will cause the inserts to vibrate and cause the inserts and needles to jump, thus causing the yarn to be scraped. In addition, long-term vibration of the needle plate will inevitably affect its service life. In response to the above problems, a solution is proposed below. Utility Model Content

[0004] The utility model aims to provide an anti-scratch yarn needle plate of a flat knitting machine, which has the advantages of reducing the friction generated during work and effectively avoiding the vibration phenomenon.
