Description

Technical Field

[0001] The utility model relates to the technical field of computer flat knitting machines, and particularly relates to a single needle-connecting motor and a stitch density double-motor driving device. Background Art

[0002] The textile and garment industry is not only a traditional industry in China, but also an important industry for China's economic development. As an important part of textile products, knitted products are deeply loved by consumers for their advantages such as softness, breathability, and comfortable wearing. With the development of technology, computer flat knitting machines have gradually replaced hand-operated flat knitting machines due to their advantages such as high speed and stable quality. The cam plate structure on the head of a computer flat knitting machine enables knitting needles to complete actions such as needle turning, needle connecting, knitting, and loop hanging. Currently, the needle-turning cams and pressers of existing computer flat knitting machines are separately controlled by their respective driving devices. When there is an error in one of the driving devices, it is easy to cause the cooperation between the needle-turning cams and the pressers to be out of sync, thereby affecting the knitting quality. At the same time, it greatly increases the structure of the cam plate and production costs. In addition, in existing computer flat knitting machines, the left and right stitch density cams adopt the same linkage structure driven by a single motor. This method not only has a complex structure, but also when one of the stitch density cams or other parts is damaged, the entire motor needs to be removed with this linkage structure for replacement or repair, greatly affecting the maintenance efficiency.
