Description

Technical Field

[0001] The present invention relates to a computer flat knitting machine needle plate that avoids the rubbing between the loop - expanding spring piece of the knitting needle and the doffing tooth opening. Background Art

[0002] The tooth opening pieces installed at the doffing opening in a computer flat knitting machine are all integral according to the existing machine types. Their spacing is calculated according to the number of needles, and the distance is constant according to the thickness of the tooth opening pieces. At the same time, the design of the height of the loop - expanding spring piece of the knitting needle, the size of the needle hook, and the thickness of the loop - connecting rod also mainly refers to the spacing of the tooth opening pieces. For a double - bed knitting and wearable computer flat knitting machine, according to its knitting principle (one - over - one needle feeding), to knit sweaters with a large quantity and wide range, such as 12 - needle and 14 - needle sweaters, a 24 - needle and 28 - needle double - bed computer flat knitting machine is required. The needle groove spacing is 1.058 and 0.907 mm. The thickness of the insert piece used for the combined needle - running needle groove and the thickness of the needle bar barely meet the usage requirements. However, the height of the loop - expanding spring piece for loop transfer cannot be further reduced and still rubs severely against the tooth opening piece with the limit thickness, resulting in a very low knitting speed. The finished product rate of the fabric still cannot be compared with that of an ordinary single - piece knitting computer machine. The call for a double - bed knitting and wearable fine - needle - pitch computer flat knitting machine that can save a large amount of manual labor in the subsequent process is extremely high and cannot be ignored. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to provide a computer flat knitting machine needle plate and its needle plate device that avoid the rubbing between the loop - expanding spring piece of the knitting needle and the doffing tooth opening.
