Description

Technical Field

[0001] The utility model relates to the field of computerized flat knitting machines, in particular to a device for preventing needles from being damaged. Background Art

[0002] The computer flat knitting machine is a double-needle plate latch needle weft knitting loom. Its triangle device is like a set of flat cams. The needle feet of the knitting needle can enter the groove of the cam and move the triangle, forcing 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 woven into a knitted fabric. During the rising process 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 rod; during the descending process of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend it into a coil. At the same time, 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 knitted stitches are connected to each other to form a knitted fabric. The existing computer flat knitting machine needles are prone to bending during transportation due to the low structural strength of the packaging box, and are in urgent need of improvement.
