Abstract

The utility model discloses a yarn adding device of a knitting machine, which belongs to knitting machinery. A traditional yarn adding device has the defects that: jacquard threads are easy to leak, the jacquard threads cannot be fed into a part of secondary shuttles, and a knitting needle is heavily abraded. The yarn adding device disclosed by the utility model comprises a secondary shuttle bracket, a crank shaft, an upper steel ring, an annular base and a secondary shuttle group, wherein the outer circle face of the upper steel ring is embedded in the annular base; the lower end of the upper steel ring is fixed on the lower end face of the annular base; a yarn feeding groove is formed on the upper end face of the upper steel ring; the secondary shuttle group consists of three secondary shuttles, namely a first secondary shuttle, a second secondary shuttle and a third secondary shuttle which are in parallel; the distances from middle through holes of the three secondary shuttles to a yarn guide nozzle are sequentially increased; the yarn guide nozzle is positioned in the yarn feeding groove; the middle through holes are sleeved on the crank shaft; one end of the crank shaft is fixedly inserted into a mounting hole on the secondary shuttle bracket; the secondary shuttle bracket is fixedly arranged on the upper end face of the annular base; a yarn baffle boss is arranged at the front end of the yarn guide nozzle to prevent colour yarns from floating up and down; and one side face of the yarn feeding groove is an inversed triangular inclined plane, so the yarn feeding width is reduced, the problem that yarns are difficult to feed to a plurality of colour jacquards in one yarn feeding groove is solved, and the abrasion of the knitting needle is reduced.

Description

A kind of knitting machine plaiting device

Technical field

The utility model belongs to the Knitting Machinery field, and is especially relevant with a kind of knitting machine plaiting device.

Background technology

Existing plaiting device as Knitting Machinery such as knitting hosiery machines mainly is made of secondary shuttle support, crank axle, last steel ring, annular seating and secondary shuttle group, the periphery of last steel ring is flush-mounted in the annular seating, last steel ring upper end is provided with rectangle yarn feeding groove, and the lower end of last steel ring is fixed on the annular seating lower surface; Secondary shuttle group is made of side by side three secondary shuttles, and secondary shuttle front end is a yarn-guide mouth, and the rear end is the rocking arm that is connected with cylinder piston, and the middle part is provided with through hole, and secondary shuttle through hole is set on the crank axle, and can rotate flexibly, and crank axle one end fixedly is plugged in the secondary shuttle bracket holes; Secondary shuttle support is fixedly installed on the annular seating upper end, and secondary shuttle front end yarn-guide mouth is positioned at the yarn feeding groove.The operation principle of this device is: during work, controlling secondary shuttle by the cylinder of computer control is the central shaft rotation with the crank axle, yarn-guide mouth is squeezed in the yarn feeding groove of steel ring in good time, at this moment the needle selection device rises in the yarn feeding groove by knitting needle control knitting needle, catch on the color yarn in the secondary shuttle mouth, move down, when needle latch is closed, take figured texture weave from top to bottom out of.Such plaiting device exists following shortcoming:

1, there is bigger gap in the color yarn in the yarn-guide mouth of secondary shuttle, easily fluctuates, thereby causes when weaving figured texture weave at a high speed, the phenomenon of eating pattern thread occurs leaking;

2, in a yarn feeding groove, wide when the polychrome jacquard weave occurring because of line feeding point, in the braiding process, the secondary shuttle of part very easily occurs and eat phenomenon less than pattern thread;

3, because of the rectangular shape of yarn feeding groove of last steel ring, the yarn feeding groove is wide, and when the braiding heel, knitting needle is prone to through this place and turns over needle latch, thereby has strengthened the pin consumption of knitting needle greatly.

The utility model content

The purpose of this utility model is exactly to occur easily leaking in the braiding process and eat pattern thread and the secondary shuttle of part and eat less than pattern thread and knitting needle and occur turning over needle latch and the big technical problem of pin consumption easily in order to solve existing plaiting device, and a kind of rational in infrastructure, line feeding stable, the pin consumption is little knitting machine plaiting device is provided.For this reason, the utility model is by the following technical solutions:

A kind of knitting machine plaiting device, comprise secondary shuttle support, crank axle, go up steel ring, annular seating and secondary shuttle group, the periphery of last steel ring is flush-mounted in the annular seating, the lower end of last steel ring is fixed on the annular seating lower surface, last steel ring upper end is provided with the yarn feeding groove, secondary shuttle group is made of side by side the first secondary shuttle, the second secondary shuttle and the 3rd secondary shuttle, the first secondary shuttle, the second secondary shuttle and the 3rd secondary shuttle front end yarn-guide mouth are positioned at the yarn feeding groove, the through hole at middle part is set on the crank axle, and can rotate flexibly, crank axle one end fixedly is plugged in the installing hole on the secondary shuttle support; Secondary shuttle support is fixedly installed on the annular seating upper end, it is characterized in that: the described first secondary shuttle, the second secondary shuttle and the 3rd secondary shuttle middle part through hole increase successively to the distance of front end yarn-guide mouth, the yarn-guide mouth front end is provided with retaining yarn boss, when yarn feeding, prevent that the color yarn from fluctuating, avoid occurring leaking the phenomenon of eating gauze broche; Described yarn feeding groove one side side is the del inclined-plane, make the yarn feeding groove bottom width less than top width, reduced the yarn feeding width, the color yarn all can be by last steel ring the landing of triangle inclined-plane to same place, thereby solved in a yarn feeding groove and the problem that the yarn difficulty is eaten in the polychrome jacquard weave occurred, simultaneously, knitting needle also is not easy to produce and turns over the needle latch phenomenon, greatly reduces the pin consumption of knitting needle.

As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic:

The described steel ring upper end of going up along the circumferential direction is provided with a plurality of yarn feeding grooves, and the quantity of described secondary shuttle group is identical with yarn feeding groove quantity.

When the utility model uses, the rocking arm of the first secondary shuttle, the second secondary shuttle and the 3rd secondary shuttle rear end be connected with cylinder respectively, move by the control system control cylinder, thereby control secondary shuttle is the central shaft rotation with the crank axle, yarn-guide mouth is squeezed in the yarn feeding groove of steel ring in good time, and the needle selection device rises in the yarn feeding groove by knitting needle control knitting needle, catches on the color yarn in the secondary shuttle mouth, move down, when needle latch is closed, take figured texture weave from top to bottom out of.

Use the utility model can reach following beneficial effect: the utility model is by being optimized design to yarn feeding groove and secondary shuttle yarn-guide mouth, makes that the plaiting apparatus structure is reasonable, line feeding stable, the pin consumption is little.
