Abstract

The utility model relates to a control mechanism for exchanging yarn which is arranged on a circular knitter and controlled by a pushing track and a needle selector to ensure the woven fabric to obtain the different effects of secondary color. The control mechanism for exchanging yarn is mainly characterized in that a groove is positioned on a yarn pushing plate in a color selection control unit, and a containing groove is arranged on a driving plate; an upper locating projecting part and a lower locating projecting part of a swing plate are respectively connected with the containing groove so as to realize accurate contraposition when a color selection plate is in motion to reduce frictional resistance and prolong the service life of the color selection plate; the groove is positioned at the bottom of a lifting board in a linkage unit, and the projecting part of one end of a connecting rod is contained in the groove, the connecting rod adopts the design of connecting two sides, so as to ensure that the process that the lifting board drives a schlagblech to exchange the yarn is labor-saving and smooth, and run-out of motion caused by timeliness wear does not occur. A piece for locking and hooking is positioned on an upper mounting unit of the control mechanism for exchanging yarn, by matching with an elastic piece, can quickly lock or break away from a fixed base of a table of the knitter, thus disassembly and assembly of the control mechanism are quicker and easier.
