Adjusting mechanism for gap of upper dial cam of circular weft knitting machine

Abstract

The invention discloses an adjusting mechanism for a gap of an upper dial cam of a circular weft knitting machine. The adjusting mechanism comprises a middle core installed on a rack of the weft knitting machine and a sleeve base installed on a head mandrel of the weft knitting machine, wherein the middle core is provided with a positioning hole; the sleeve base is provided with a fixing ring; thefixing ring is provided with a screw hole coaxial with the positioning hole; a lifting screw used for adjusting the installation position of the middle core is arranged in the positioning hole; and the lifting screw is provided with a lifting screw rod in the axial direction, and the lifting screw rod penetrates through the screw hole of the fixing ring. According to the invention, the lifting screw capable of adjusting the position of the middle core and the lifting screw rod are installed on the middle core, so that the distance between the upper dial cam and an upper dial is adjusted, goodstability of weaving is guaranteed, the phenomenon that the middle core moves again can be avoided, the installation precision of equipment is higher, and the operation of the equipment is more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to an adjustment mechanism for the cam clearance of the upper plate of a circular weft knitting machine. Background technique [0002] In order to meet the production requirements of products with different specifications, especially for high-quality and high-density circular weft knitting machines, the gap between the upper plate cam and the upper dial needs to be adjusted, and the upper plate cam is installed on the upper plate cutting block If the upper disk is cut into pieces and installed on the middle kernel, then the installation position of the middle kernel needs to be adjusted. Due to the poor stability of the existing position adjustment method between the middle kernel and the sleeve base, the distance between the triangle of the upper disk and the upper dial The gap will change. As a result, some uneven stripes and other defects usually appear in the transver...

Problems solved by technology

[0002] In order to meet the production requirements of products with different specifications, especially for high-quality and high-density circular weft knitting machines, the gap between the upper plate cam and the upper dial needs to be adjusted, and the upper plate cam is installed on the upper plate cutting block If the upper disk is cut into pieces and installed on the middle kernel, then the installation position of the middle kernel needs to be adjusted. Due to the poor stability of the existing position adjustment method between the middle kernel and the sleeve base, the distance between the triangle of the upper disk and the upper needle disk Gap will change

As a result, some uneven stripes and other defects usually appear in the horizontal direction of the weaving fabric, and the stability of the product is poor.
