Description

Technical Field

[0001] The invention relates to the field of circular knitting machine cloth defect camera devices, in particular to a circular knitting machine cloth inspection camera device. Background Art

[0002] In the process of producing cloth, circular knitting machines inevitably have various defects due to various reasons, such as problems with yarn, yarn feeder, environment or textile process. Some defects are visible to the naked eye, while others are invisible to the naked eye and can only be identified with the help of instruments. Using an adjustable camera to capture defects is an effective method. At present, most circular knitting machines, especially open-width machines, have not yet used the process of using an adjustable camera to capture defects. It is only used in some relatively small circular knitting machines. The method of use is: place the camera in the needle cylinder of the large circular knitting machine and above the cloth support frame. Especially for double-sided machines, the camera will be wrapped in the cloth. After long-term use, flying catkins will dirty the lens, making it impossible for the camera to capture defects in a timely and accurate manner, causing losses. In addition, due to the structure of some circular knitting machines, the camera is installed on the scanning path with a load-bearing rod, which affects the inspection effect.
