Description

Technical Field

[0001] The utility model belongs to the technical field of hosiery knitting machines, in particular to a thread trimming device of a hosiery knitting machine. Background Art

[0002] The thread trimming device on the hosiery knitting machine consists of a cap cover and a disc scissors. The cap cover is the main component of the hosiery knitting machine and plays a direct role in knitting loops. The cap cover is equipped with a yarn feeding device and the disc scissors cooperate with the cap cover to complete the thread trimming task. The traditional cap cover and the disc scissors are fixed as a whole and connected to the upper seat plate of the hosiery machine through the cap seat. The reason is that the power of the disc scissors is provided by the only motor in the hosiery machine through a mechanical transmission device, and the scissor disc cannot be separated from the cap cover.

[0003] According to a disclosed thread trimming device for a hosiery machine (publication number: CN2609945Y), the coordination relationship between the whole formed by the disc scissors, the transmission mechanism, the motor and the bracket and the hat cover is a movable connection. The whole formed by the disc scissors and its bracket motor transmission mechanism can be rotated and turned up relative to the hat cover, or can be vertically moved up and down relative to the hat cover. In this way, it is very convenient during debugging and maintenance. However, in the above device, it is difficult to fix the socks during cutting through the coordination of components such as the disc scissors and the transmission mechanism, resulting in uneven cutting cuts, which needs to be improved.
