Description

Technical Field

[0001] The utility model relates to the technical field of computerized flat knitting machine production, in particular to a needle selection piece structure for a computerized flat knitting machine. Background Technique

[0002] In the knitting of a computerized flat knitting machine, there are three knitting needles in a knitting section, which is called three sections, and five knitting needles, which is called five sections. Commonly used are three sections, five sections, six sections, eight sections and ten sections. In a super-dense needle machine type, fourteen sections are required for knitting.

[0003] According to the utility model patent application with the publication number: CN201212085Y and the publication date of March 25, 2009, an improved multi-functional needle selection piece for a computerized knitting flat machine is disclosed, belonging to the technical field of knitting machinery. Its characteristics are: the multi-functional needle selection piece is in a long shape, the back of the tail is slightly inclined, and the middle of the back D is concave. The needle selection part on the upper plane is in a staircase shape and gradually increases from top to bottom. It has a needle abutting surface G at its top, a needle blocking surface E behind the needle abutting surface G, a needle blocking surface F at its tail, and the needle abutting surface G is slightly convex. Its advantages are: the multi-functional needle selection piece combines the two functions of a needle selection piece and a guide needle piece into one.
