Description

Yarn feeding device of knitting machine

Technical Field

The utility model relates to the technical field of textile, in particular to a yarn feeding device of a knitting machine.

Background

The knitting machine is a machine which uses knitting to form loops by various raw materials and various yarns, and then connects the loops into knitted fabrics through a string sleeve, and before the knitting machine works, yarn coils are required to be fixed, and then the yarn coils are threaded one by one and fixed on corresponding needle heads. When knitting, a plurality of yarns are conveyed through the conveying rollers and conveyed into knitting equipment for production, in order to ensure the quality of producing knitted sweater, the tensioning degree of the yarns in the moving process needs to be accurately controlled, the tensioning degree is usually adjusted through the up-and-down movement of the conveying rollers by the existing tensioning control equipment, the adjusting range is large, and the accurate and flexible control cannot be realized.

The Chinese patent with the authority bulletin number of CN218088357U discloses a yarn feeding tensioning mechanism for producing knitted sweater, which comprises a mounting rack, wherein two ends of the mounting rack are respectively provided with a feeding roller and a discharging roller, the mounting rack is positioned between the feeding roller and the discharging roller and is provided with a tensioning adjusting component, the tensioning adjusting component comprises an adjusting frame, two ends of the adjusting frame are respectively connected with a first sliding block and a second sliding block in a rotating manner through a short shaft, the first sliding block and the second sliding block are vertically and slidably connected with the mounting rack, two sides of the adjusting frame are rotatably connected with conveying rollers, yarns pass through the upper parts of the feeding roller and the discharging roller and pass through the space between the two conveying rollers, and the end part of the adjusting frame is provided with a rotating mechanism; according to the utility model, the conveying rollers at two sides are driven to swing through the rotation of the adjusting frame, so that the tensioning degree can be accurately controlled, yarn breakage is avoided, and when the yarn is too loose, the up-and-down movement of the adjusting frame is adjusted through the up-and-down sliding of the first sliding block and the second sliding block, so that different adjusting requirements are met.

However, the device still has the defects that: according to the known technology, when the knitting machine works, yarns with corresponding color numbers are automatically selected according to different color matching, at the moment, the yarns with other color numbers are kept still, if the phenomenon of yarn supply looseness occurs, only the yarns with the color numbers are needed to be tensioned and adjusted, however, the device synchronously adjusts the yarns with all color numbers, so that the situation that the yarns with the other color numbers are too loose or too tight is easily caused, and meanwhile, the device needs to use a telescopic motor during adjustment, and the adjustment of the telescopic motor has certain hysteresis and is slower in response.
