Description

Technical Field

[0001] The utility model relates to the technical field of circular knitting machines, in particular to a yarn feeding regulating mechanism for a full-automatic jacquard machine. Background Art

[0002] Needle spinning machinery is a common textile machinery equipment. In many knitting enterprises, small-diameter circular knitting machines are commonly used. Small-diameter circular knitting machines are usually divided into two types: ordinary circular knitting machines and jacquard circular knitting machines. The former weaves fabrics with simple organizational structures, while the latter can weave fabrics with multi-color jacquard structures. In the process of fabric weaving, small-diameter circular knitting machines usually use pre-designed jacquard patterns. The colored yarns of the loop forming system are padded from the weft direction onto the selected and elevated knitting needles to form loops, while the other needles that have not been selected are in a low working position waiting for other loop forming systems to select needles to form loops.

[0003] The ultra-precision fully automatic jacquard circular knitting machine in the prior art can arrange forty needles at a distance of one inch. In order to ensure the stability of the yarn feeding tension, the fiber tension is generally adjusted in real time through an electronic yarn discharger. Due to the one-line-one-device setting, in order to ensure the amount of yarn fed, the yarn discharge frame above the circular knitting machine will be covered with electronic yarn dischargers. Therefore, there will be friction between the yarn and the support column on both sides of the circular knitting machine support column. Due to the high friction distance between the yarn and the support column, tension fluctuations and even wire breakage are likely to occur. Generally, the yarn feeding in the direction of the support column is directly cancelled. Although this can solve the problem, it will also reduce the knitting processing efficiency and has further room for improvement. Utility Model Content

Fixing screws 10 are fixedly connected to the top of both sides of the three support columns 3 through the fixing screw holes 8. Yarn feed regulators 9 are rotatably connected to the top of both sides of the three support columns 3 through the fixing screws 10. The direction of the yarn feed can be adjusted by deflecting the yarn feed porcelain eye 93 provided on the yarn feed regulator 9, which can effectively prevent the yarn feed from rubbing against the two sides of the support column 3. There is no need to cancel the yarn feed in the direction of the support column 3, thereby ensuring the efficiency of the knitting process. The yarn feed regulator 9 includes a connecting plate 91, an embedded plate 92, a yarn feed porcelain eye 93 and a connecting hole 94. The middle parts of both ends of the connecting plate 91 are opened A connecting hole 94 is provided, and a fixing screw 10 passes through the connecting hole 94 above the connecting plate 91 and is movably connected to the connecting hole 94. An embedded plate 92 is vertically arranged on the side of the connecting plate 91 close to the braider fixing frame 7, and a plurality of yarn feeding porcelain eyes 93 are equidistantly inlaid on the side of the embedded plate 92 away from the connecting plate 91.

[0026] Reference Figure 4 The difference between this embodiment and the first embodiment is that the yarn feed regulator 9 includes a connecting plate 91, an embedding plate 92, a yarn feed porcelain eye 93 and a connecting hole 94. A connecting hole 94 is provided in the middle of both ends of the connecting plate 91.
