Positioning device for knitting printing processing

The invention relates to a positioning device, in particular to a positioning device for knitting printing processing. The positioning device for knitting printing processing can directly position knitted clothes in a rigid mode and improve the follow-up positioning effect. A positioning device for knitting printing processing comprises a base, furniture, electric guide rails and the like, the electric guide rails are fixedly connected to the rear side face of the base in a bilateral symmetry mode, and a clamp used for clamping and fixing different printing plates is connected between the electric guide rails on the left side and the right side in a sliding mode. Knitted clothes are firstly placed on the ink pad, then the annular frame is pushed to move downwards to press and fix the knitted clothes, meanwhile, the annular frame further drives the air bag to move downwards, the air bag moves downwards to make contact with the knitted clothes, meanwhile, the air bag expands continuously to rigidly position the
