Description

Coil Transfer Structure of Circular Knitting Machine

This creation is about a loop knitting machine structure, especially a loop transfer structure of a loop knitting machine.

Press, when making general socks, usually a circular knitting machine is used to knit a hollow circular knitted product first. At this time, the loops of the last row of the hollow circular knitted product are located on the plurality of knitting needles of the circular knitting machine. Then transfer the loops of the last row to a suturing device. The suturing device is annular and includes a fixed part and a movable part. The fixed part and the movable part are semi-annular, and the movable part can be rotated downward. About 180 degrees of overlapping with the fixed part, the fixed part and the peripheral edge of the movable part are provided with a plurality of point needles extending downward, the point needles can be driven by the suturing device to move up and down, and the lower sides of the point needles are respectively equipped with a sinker The sinker can move laterally and up and down.

The transfer action is to control the downward displacement of the point needle, so that the end of the point needle is connected to the top of the knitting needle, the loop on the knitting needle is driven up to the point needle by the sinker, and then the movable part of the stitching device is rotated downward about 180 degrees and The fixed parts are butted and overlapped, so that the end of the needle of the movable part and the end of the needle of the fixed part are butted, and the loop on the needle of the movable part and the loop of the needle of the fixed part are pushed together, and then use a The sewing needle will stitch the loops together to complete the toe seal of the sock.

However, in the above-mentioned conventional structure, the docking between the point needle and the knitting needle and the butt between the point needle and the point needle all require precise positioning control, otherwise the situation that cannot be smoothly transferred is likely to occur, forcing the operator to stop the machine. It affects the efficiency of hosiery, product yield and quality.

In view of the above-mentioned shortcomings of the loop transfer structure of the conventional circular knitting machine, the creator of this project has come up with the idea of creation.

The present invention provides a loop transfer structure for an endless knitting machine, comprising: a plurality of knitting needles, each of the knitting needles has a needle bar, one end of the needle bar is provided with a needle hook and a needle latch is pivotally connected, and the needle latch can be movably pivoted. The hook is closed up or opened down; a plurality of first point needles, the first point needles can be displaced up and down to approach or away from the hooks of the knitting needles, and the end of each first point needle is provided with a first docking part , the inner side of the first butt portion is provided with a circular arc groove, and the lower side is provided with a snap end, the first butt portion can be connected with the knitting needle, and the arc groove of the first butt joint portion covers the knitting needle and a plurality of second point needles, the second point needles can be displaced up and down to be close to or away from the needle hooks of the knitting needles, and the end of each of the second point needles is provided with a second abutting portion, The inner side of the second abutting portion is provided with a slot, and the second abutting portion can be butted with the hook of the knitting needle. The second abutting portion can be abutted with the first abutting portion, and the slot of the second abutting portion is sleeved on the engaging end of the first abutting portion and is positioned in abutment.

The main purpose of creating the loop transfer structure of the circular knitting machine is that when the second point needle is in contact with the knitting needle, the slot of the second abutting portion is fitted over the hook of the knitting needle and the hook is aligned and positioned. And when the second point needle is connected with the first point needle, the slot of the second abutting portion is fitted with the engaging end of the first abutting portion to snap and align, so as to improve production efficiency and product quality. And the product defect rate is reduced.
