Description

Color-changing head of knitting machine Technical Field The invention relates to the technical field of knitting machines, in particular to a color-changing head of a knitting machine. Background The color-changing knitting machine is characterized in that a plurality of color-changing heads are arranged on the knitting machine to realize the color-changing effect of the fabric. Firstly, a compression bar fixing seat is arranged on a knitting machine, and a color changing head is vertically arranged below the compression bar fixing seat. During production, if the color-changing head is problematic, the color-changing head needs to be detached from the compression bar fixing seat for maintenance, and because the color-changing head is tightly installed, the disassembly and the installation are very complicated, a great deal of time and energy are required to be consumed, and the maintenance cost is high. In addition, the color-changing head for the existing knitting machine is assembled with a plurality of color-changing head cutter components, and the color-changing head cutter components comprise an upper fixing plate, a lower fixing plate, a crochet hook and a cutter, wherein the upper fixing plate and the lower fixing plate are fixedly arranged, and the crochet hook and the cutter are clamped between the upper fixing plate and the lower fixing plate. The existing color-changing head cutter assembly has the defects that the cutter, an upper fixing plate and a lower fixing plate are fixed together, and the position cannot be moved. When certain special yarns are processed, yarn cutting positions are different, the color-changing head cutter assembly needs to be replaced, the production and manufacturing cost is high, and the requirement is not met if the color-changing head cutter assembly is not replaced. Accordingly, there is a need for an improvement over existing color-changing heads based on the above-described drawbacks of existing color-changing heads. Disclosure of Invention The invention aims to provide a color-changing head of a knitting machine, which solves the defects of very complicated disassembly and assembly, high maintenance cost and the like of the existing color-changing head. In order to achieve the above object, the present invention is achieved by the following technical scheme. A color-changing head of a knitting machine comprises a cover plate, wherein a first notch is formed in the upper end of the cover plate, a pressing handle and a positioning plate are rotatably arranged on the cover plate, the pressing handle is provided with an upper buckling part, the upper buckling part is rotatably located above the first notch, a gear is arranged on the right side of the upper end of the cover plate, the positioning plate is provided with a positioning part, the positioning part is rotatably clamped into the gear position of the gear, and the pressing handle is in linkage with the positioning plate. Further, the pressing handle is provided with a first latch, the positioning plate is provided with a second latch, the first latch and the second latch are meshed, and the pressing handle and the positioning plate are guaranteed to be linked through the meshing of the first latch and the second latch.
