Description

Sheeting in flat knitting machine

Technical Field

The invention belongs to the technical field of knitting machinery, and particularly relates to a tabletting in a flat knitting machine.

Background

In the process of knitting the panel, the knitting and transferring are indispensable knitting requirements for the panel. The advantages and disadvantages of looping and stitch stabilization depend on whether the stitch is properly matched with the crochet needle, and the stitch is properly matched with the crochet needle, which can be accomplished by pulling the garment piece or pressing the stitch. The sinkers are an important component of the pressing coil to assist in looping.

The sinker of the existing flat knitting machine realizes the downward pressing of yarns through the thrust of a push needle triangle and the circular arc motion by taking a steel wire as an axis, and then the downward pressing of the yarns enters a knitting area, but the traditional sinker cannot press the yarns floating at a nozzle, so that the yarns floating at the nozzle cannot be pressed below a knitting needle, the problem of floating occurs, and the quality of knitting products is affected.

Disclosure of Invention

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a preform capable of pressing a yarn floating at a nozzle well to a flat knitting machine below a knitting needle.

For this purpose, the technical scheme of the invention is as follows: sheeting in flat knitting machine, including a slice form body, its characterized in that: the bottom of the sheet-shaped body is provided with a bent yarn pressing part, and the yarn pressing part is provided with a concave yarn passing groove; the size of a groove at one end of the wire passing groove is larger than that of a groove at the other end, the wire passing groove is divided into a large-caliber end and a small-caliber end, the groove size of the wire passing groove is gradually reduced from the large-caliber end to the small-caliber end, and the wire passing groove is transited through an arc surface; the edge of the opening of the wire passing groove is of an inclined structure, an included angle exists between the opening of the wire passing groove and a horizontal line, and the opening of the wire passing groove is inclined downwards from the large-caliber end of the wire passing groove to the small-caliber end.

Preferably, an included angle exists between the opening direction of the wire passing groove and the plane of the sheet-shaped body.

Preferably, the large-caliber end of the thread passing groove is an inlet end, and the yarn is guided into the thread passing groove from the large-caliber end and is pressed down to the thread hooking position from the small-caliber end.

The pressing sheet is arranged above the opening (the gap between the two needle beds) of the needle bed, the sheet-shaped body of the pressing sheet is integrally inclined to form a certain included angle with the position of the opening, yarn blocking during working is avoided, the bent yarn pressing part of the pressing sheet is opposite to the position of the opening, and the opening direction of the wire passing groove is opposite to the opening.

Because the yarn is the incline state when colluding the yarn, if cross the wire casing and be the horizontality, then there is the contained angle between wire casing and the yarn, during operation, can appear the preforming and press the yarn or only push down partial yarn to influence the stability of whole yarn pressing work. Therefore, the edge of the wire passing groove is not parallel to the hole, the small-caliber end of the wire passing groove is closer to the hole, and the small-caliber end can extend into the hole. When the yarn is pressed, the notch at the large caliber end is relatively large, so that the yarn is pressed conveniently, and the yarn guide device has a guide function and can guide the yarn into the yarn passing groove; the notch at the small-caliber end is smaller, so that the positions of yarns are concentrated and can be positioned right above the hole; when the pressing sheet is pressed down, the small-caliber end can extend into the hole to press the yarn down to the yarn hooking position, so that the knitting needle on the needle bed is convenient for hooking the yarn.

The yarn is pressed by the yarn passing groove at the bottom of the pressing sheet, the whole yarn passing groove is in an inclined state, and the yarn passing groove is matched with the introduced yarn, so that the yarn is easier to press down; meanwhile, the calibers at the two ends of the thread passing groove are different in size, the large caliber end is used for guiding yarns to enter, and the small caliber end is convenient for positioning and pressing down the yarns, so that the yarns floating at the cylinder opening can be better pressed below the knitting needles, and floating yarns are avoided.

FIGS. 1 and 2 are schematic structural views of the present invention;

FIG. 3 is a front view of the present invention;

FIG. 4 is a side view of the large diameter end of the wire chase of the present disclosure;

FIG. 5 is a side view of the small diameter end of the wire chase of the present disclosure;

fig. 6 is a schematic diagram of the operation of the present invention.

Marked in the figure as: the yarn feeding device comprises a sheet-shaped body 1, a yarn pressing part 11, a yarn passing groove 12, a large-caliber end 121, a small-caliber end 122, a border line 123, an opening 2, yarns 3, a needle bed 4 and knitting needles 41.

Detailed Description

See the drawings. The preforming of this embodiment is arranged in the entrance to a cave 2 (the clearance of two needle beds) top of needle bed 4, and the slice body 1 of preforming is whole to be inclined, is certain contained angle with the position in entrance to a cave place, avoids the during operation to keep off the yarn, and slice body bottom is equipped with the yarn portion 11 of pressing of a buckle, and yarn portion and entrance to a cave position are relative, are equipped with the wire casing 12 that the opening was down on the yarn portion of pressing, and the opening direction of wire casing is just right to the entrance to a cave.

The groove shape of the wire passing groove 12 is similar to a truncated cone structure, wherein the size of the groove at one end is larger than that of the groove at the other end, and the groove is divided into a large-caliber end 121 and a small-caliber end 122, the opening size of the groove at the large-caliber end 121 and the depth of the groove gradually decrease and become shallow towards the small-caliber end 122, and the inside of the groove is transited through a smooth arc surface, namely the whole wire passing groove is reduced and inclined from the large-caliber end to the small-caliber end; the large diameter end 121 of the yarn passing groove is the inlet end and can guide yarn into the yarn passing groove, while the small diameter end 122 can limit the position of the yarn so that the yarn is positioned right above the opening and can be pressed down to the yarn hooking position.

The bottom of the sheet-shaped body 1 is in an inclined state, namely, the edge line 123 of the opening of the wire passing groove is not parallel to the horizontal line of the opening, the groove wall of the wire passing groove is not of equal width, the groove opening is provided with non-parallel edges, and the large caliber end of the wire passing groove faces the small caliber end and is inclined downwards. When the yarn is pressed down, the yarn is in an inclined state, the yarn passing groove is matched with the yarn, the yarn can be pressed better, the small-caliber end is closer to the hole and also stretches into the hole earlier, and the large-caliber end can not enter the hole.

When the yarn feeding device works, the pressing sheet is arranged above the opening (a gap between two needle beds) of the needle bed, the opening direction of the yarn feeding groove 12 is opposite to the opening 2, the yarn 3 is guided into the yarn feeding groove by the large-caliber end 121 of the yarn feeding groove, and the small-caliber end 122 of the yarn feeding groove guides the yarn to the position right above the opening; when the pressing sheet is pressed down, the small-caliber end 122 drives the yarn to extend into the hole, and the yarn 3 is pressed down to the thread hooking position, so that the knitting needle 41 on the needle bed 4 can hook the yarn conveniently.
