Embodiment 1

[0039] like figure 1 and figure 2 As shown, the present invention proposes a single-leg all-round yarn presser for a circular weft knitting machine, comprising a yarn pressing assembly 1 and a fixing bracket 2, wherein,

[0040] The yarn pressing assembly 1 is an integrally formed sheet, including:

[0041]A prismatic or cylindrical yarn pressing portion 10 located above the yarn pressing assembly 1 is used for yarn pressing. In order to avoid needle strike, the cross-sectional diameter of the yarn pressing portion 10 of the yarn pressing assembly 1 does not exceed the needle back of the dial knitting needle. The diameter of the cavity formed by the needle back of the needle cylinder and the three positions of the needle head at the flat mouth of the needle cylinder, and a safety distance should be reserved to prevent the needle from striking. The required rigidity and strength; the side length or diameter range of the cross section can be selected according to the model of...

Embodiment 2

[0047] In order to better fix the yarn pressing assembly 1 on the circular weft knitting machine, this embodiment perfects the fixing bracket on the premise of the first embodiment. like figure 1 and figure 2 shown, is a schematic diagram of the overall structure of this embodiment. In this embodiment, the fixing bracket 2 is detachably connected to the supporting portion 12, and the fixing bracket 2 includes a bracket connecting portion 20 and a fixing portion 21 that are connected in an L-shape, wherein,

[0048] The width of the bracket connecting portion 20 is smaller than the width of the upper edge of the support portion 12, so that the support portion 12 can be overlapped and fixed with the yarn presser and is provided with at least one set of horizontally arranged limit holes 200, each set of the limit holes 200 corresponds to the position of the limit groove 121 of the support portion 12 and is fixed by screw connection; the number of the limit holes 200 in each gr...

Abstract

The invention discloses a single-leg omnipotent yarn presser for a circular weft knitting machine, which relates to the field of mechanical components of a circular weft knitting machine. The invention comprises a yarn pressing component and a fixing bracket. : Yarn pressing part used for pressing yarn, which is prismatic or cylindrical; The lower surface is in the shape of a slope whose thickness decreases sequentially from the inner edge to the outer edge; the support part is a polygon with the upper and lower bottom sides parallel to the yarn pressing part, the left and right sides are symmetrical and has a concave chamfer, and the support part is in the shape of a polygon with the upper and lower bottom sides parallel to the yarn pressing part, the left and right sides being symmetrical and having concave lead angles. The yarn part forms a rectangular cavity in parallel; the fixing bracket is an integrally formed bracket, which is connected with the supporting part and is used for fixing the yarn pressing assembly. The invention can realize yarn pressing without affecting the simultaneous needle ejection of the needle disc and the needle cylinder, avoid needle strikes during knitting, and improve knitting efficiency; the structure is simple, and it is favorable for popularization and application.

Description

technical field [0001] The invention relates to the field of mechanical parts of circular weft knitting machines, in particular to a single-leg omnipotent yarn presser for circular weft knitting machines. Background technique [0002] At present, in the known double-sided circular weft knitting machine, when the gauge of the knitting machine is greater than 12 needles, the distance between the two needle beds is generally within 3 mm, within this distance, the knitting machine can meet the usual The weaving requirements of the weft knitting structure, however, when using the double-sided circular weft knitting machine to weave the spacer fabric, especially when the distance between the two surface layers of the fabric is large, the existing machine only relies on the action of the pulling and winding mechanism Pulling, the function of knitting needles can not be guaranteed, especially the withdrawal of lower needles, so it can not be knitted normally. In order to solve the ...
