Combined insertion piece

Abstract

The invention relates to a combined insert. Its technical solution is: insert it into the insert slot on the needle plate, insert the plug iron slot on it into the plug iron, it includes the first insert (I) and the second insert (II), and several adjacently arranged The first insertion piece (I) and the second insertion piece (II) form the first insertion piece (I) group and the second insertion piece (II) group respectively, and the first insertion piece (I) group and the second insertion piece The groups of pieces (II) are arranged alternately on the needle plate; the head of the first piece (I) of the insertion piece is straight, and a plug iron groove is arranged on it; the second piece (II) has a raised The head is provided with a sinker needle plate insertion groove, and a plug iron hole is provided at the position corresponding to the first (I) of the insertion piece on the lower side of the groove; The plug iron slot on the first insert (I) and the plug iron hole on the second insert (II). Its beneficial effects are: the position of the plug iron inserted on it can move forward to the limit position allowed by the structure, the groove width of the plug iron groove is almost doubled, the stability of the front end of the knitting needle is obviously strengthened, and the knitting needle is improved. The stability of the needle knitting action improves the knitting quality of the flat knitting machine.

Description

technical field [0001] The invention relates to a knitting machine, in particular to a combined insert on a needle plate. Background technique [0002] The inserts are inserted into a number of insert slots arranged in parallel on the needle plate of the flat knitting machine, and the needle plate is divided into several needle slots for placing knitting needles and related needle butts and inserting and installing related zeros on the needle plate. part. The structure of the existing insert is as follows Image 6 As shown, there is a protruding head 11 at the front end of the insertion piece 10, on which a sinker needle plate insertion groove 12 is provided, and a plug iron groove 13 is provided on the inner side of the protruding head 11. Sinker needle plate insertion slot 12 is used to install sinker needle plate 2, plug iron slot 13 is used to insert plug iron 3, please refer to Figure 7 . The plug iron 3 is on the upper side of the needle groove where the knitting n...

Problems solved by technology

However, the structure of the existing insert makes it impossible to move the position of the plug iron groove 13 forward or to widen the groove width, so it is difficult to improve the stability of the knitting needle movement on the original basis, which is very important for improving the knitting quality. Unfavorable, especially when the knitting needle is used for transfer, the knitting needle needs to move smoothly and the needle should be ejected accurately

This is because: the knitting needle 4 on the high needle side has a high needle-out position, and the contact length C between its rear part and the plug iron becomes shorter, and the groove width L length without the plug iron groove 13 is C<L, and its front part stretches The length becomes longer, the stability of the knitting needle 4 is poor, and it is easy to shake. The accuracy of inserting the knitting needle 4' on the low needle side into the corresponding stitch on the high needle position is affected, and it is easy to form missing stitches.
