Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of knitting machinery, and in particular to a digital display installation and detection tooling for a needle selector. Background Art

[0002] Knitting machines such as circular knitting machines have developed rapidly and have been widely used because of their multiple loop forming systems, high speed, high output, fast pattern change, good fabric quality, fewer processes and strong product adaptability.

[0003] The knitting needles are installed on the needle cylinder of the knitting needle circular knitting machine. When knitting jacquard tissues, tuck tissues and other colored tissues on seamless knitting needle circular knitting machines and other equipment, some knitting needles need to be selectively involved in the knitting work (looping or tuck) or not involved in the knitting work (not knitting). The needle selector selects the knitting needles through the needle selection blade according to the pattern information stored in the computer memory to ensure the correct knitting pattern. The needle selector is installed in the slide of the knitting needle circular knitting machine. The needle selection blade of the needle selector has a small stroke, and the distance between the needle selection blade and the needle cylinder is very small, generally in the range of 0.2-0.3mm, so the installation and assembly accuracy of the needle selector is required to be high.

[0004] The inventors of the present application have discovered that, currently, when installing a needle selector, the installer generally adjusts the position of the needle selector by measuring with a feeler gauge, and multiple manual fine-tuning of the needle selector installation position is required to meet the installation requirements. This takes a long time, and the installation and adjustment process is cumbersome and inefficient. Utility Model Content

[0035] As described in the background technology of this application, the needle selector is installed in the slide groove of the circular knitting machine. The needle selector blade of the needle selector has a small stroke, and the distance between the needle selector blade and the needle cylinder is very small, generally in the range of 0.2-0.3mm. Therefore, the installation and assembly accuracy of the needle selector is required to be high.

[0036] The inventors of the present application have discovered that, currently, when installing a needle selector, the installer generally adjusts the position of the needle selector by measuring with a feeler gauge, and multiple manual fine-tuning of the needle selector installation position is required to meet the installation requirements. This takes a long time, and the installation and adjustment process is cumbersome and inefficient.

[0037] In order to solve the above problems, the inventor of the present application proposed the technical solution of the present application, and the specific embodiments are as follows:
