Gripping device for circular knitted fabrics

Abstract

The invention discloses a grabbing device for circular knitted fabrics, comprising a grabbing mechanism arranged above a needle cylinder, the grabbing mechanism comprising a base, a fixed half ring and a movable half ring which can be matched to form a circular ring structure are arranged below the base, the movable half ring can rotate 180 degrees and is hingedly matched with the fixed half ring, a connecting arm assembly is arranged between the movable half ring and the fixed half ring, and grabbing needle mechanisms are arranged on the outer peripheries of the fixed half ring and the movable half ring respectively; a lifting mechanism connected to a negative pressure system is arranged above the base, and before the sewing mechanism performs the sewing operation, the lifting mechanism passes through the circular ring structure formed by the fixed half ring and the movable half ring, and extends into the circular knitted fabric, fixes the lower part of the circular knitted fabric, and then lifts and flips it upward. The advantages of the invention are: compact and reasonable structure, convenient control, and the ability to achieve rapid connection of the circular knitted fabric from the knitting process to the sewing process, thereby improving production efficiency.
