Circular knitting machine for integrating multi-yarn changing device

Abstract

A circular knitting machine for integrating a multi-yarn changing device comprises a first yarn changing device, a second yarn changing device, a driving cam group and at least a cylinder seat provided with a plurality of knitting needles. The first yarn changing device and the second yarn changing device are respectively provided with at least a yarn feeding mechanism; and the yarn feeding mechanisms move towards a yarn feeding position for providing yarns by passing through a first yarn feeding route and a second yarn feeding route respectively. The driving cam group comprises a first driving orbit and a second driving orbit respectively pushing the yarn feeding mechanisms to perform the first and second yarn feeding routes; and a driving delay section is further arranged in the second driving orbit so that the yarn feeding mechanisms of the first and second yarn changing devices generate a yarn feeding time difference when respectively performing the first and second yarn feeding routes. The knitting needles positioned between the yarn feeding mechanisms relative to the first and second yarn changing devices are guided to move to a yarn hooking position, and respectively hook the yarns provided by the yarn feeding mechanisms of the first and second yarn changing devices according to the yarn feeding time difference.

Description

technical field [0001] The invention relates to a circular knitting machine with a yarn changing device, in particular to a circular knitting machine integrating multiple yarn changing devices. Background technique [0002] In order to increase the diversification of fabric weaving effects, the technology of adding other colors or types of yarns to the circular knitting machine with a yarn changing device when weaving fabrics has been widely used in the industry, such as US Patent No. 7,036,343 , US Patent No. 7,055,348, US Patent No. 6,655,176, and US Patent No. 5,218,845, etc. [0003] Taking U.S. Patent No. 5,218,845 as an example, the disclosed yarn changing device 10 has a structure as follows: Figure 1-1 to Figure 1-4 As shown, it mainly includes a yarn feeding board 11 , a clamping yarn board 12 and a partition 13 . In the state of not feeding yarn, the yarn feeding plate 11 and the clamping yarn plate 12 are both received in the yarn changing device 10, and the cla...

AI Technical Summary

Problems solved by technology

If the yarn cannot be disengaged from the meshing member smoothly due to too much clamping force, or the yarn is separated from the meshing member early due to insufficient clamping force, it will cause the yarn change to be unable to proceed smoothly and affect the quality of the braided fabric
