Description

Positioning and adjusting structure for circular weft knitting machine Technical Field The invention relates to the technical field of circular weft knitting machines, in particular to a positioning and adjusting structure for a circular weft knitting machine. Background In the working process of the circular weft knitting machine, the height of the lower saddle is required to be adjusted, a locking screw is usually screwed, and then the gap between the lower saddle and the base is adjusted, so that the aim of adjusting the height of the lower saddle is fulfilled. In the related art, a positioning adjusting structure for a circular weft knitting machine, such as a publication number CN113564792B, comprises a large disc, a lower saddle detachably connected with the large disc is arranged on the large disc, a plurality of positioning components are annularly arranged on the lower saddle and used for positioning between the lower saddle and the large disc, after a locking screw is taken out, a gap between the lower saddle and the large disc can be adjusted through the adjusting screw, when the lower saddle moves, the top of a positioning pin is always positioned in a first slotted hole, positioning between the lower saddle and the large disc is realized through cooperation between a connecting column and the positioning pin, and the lower saddle is effectively prevented from shifting in the adjusting process.
