Disclosure of Invention

In order to solve the problems, the utility model provides a shoes and socks machine put the yarn board, it makes the yarn that the yarn mouth of middle zone fed can not produce the closed angle friction with putting the yarn board, has improved the yarn feed effect, has prevented anti-yarn, improves yarn feed stability.

The yarn releasing plate of the footwear machine is characterized in that: the yarn placing plate comprises a yarn placing plate body, wherein a concave placing groove is formed in the region, corresponding to a yarn nozzle, of the yarn placing plate body, a lower groove is formed in the width region, corresponding to the middle yarn nozzle, of the concave placing groove, the periphery of the lower groove is of a closed structure, the outer peripheral surface of the lower groove is connected with a reference surface of the placed concave placing groove through an expanding inclined surface from bottom to top, and guide regions, corresponding to the inclined two sides of yarns, of the lower groove are in fillet transition.

It is further characterized in that:

the width surface area of the lower groove covers the corresponding number of yarn nozzles of the middle area which need to have position change in the height direction;

the other end of the lower groove in the length direction is a large-diameter arc profile, so that the yarn nozzle is prevented from being in hard contact with the boundary of the reference surface of the lower groove, and the abrasion is ensured to be as small as possible;

the two sides of the yarn releasing plate body in the width direction are respectively provided with long groove positioning holes, and the long groove positioning holes ensure that the yarn releasing plate body is installed quickly and conveniently.

After adopting above-mentioned technical scheme, the yarn is through the in-process that middle yarn mouth fed yarn, and the yarn is when upwards outwards leading with correspond the flaring inclined plane contact that has the fillet transition for the yarn that middle zone's yarn mouth fed can not produce the closed angle friction with putting the yarn board owing to be face contact, and be the fillet face region, improved the yarn effect of feeding, prevent anti-yarn, improve and feed yarn stability.

Drawings

FIG. 1 is a schematic perspective view of a conventional yarn feeding plate;

fig. 2 is a schematic structural view of a perspective view of the present invention;

the names corresponding to the sequence numbers in the figure are as follows:

the yarn placing plate comprises a yarn placing plate body 1, a concave placing groove 2, a concave placing groove reference surface 21, a lower groove 3, a flaring inclined surface 4, a fillet transition 5, a large-diameter arc contour 6 and a long groove positioning hole 7.

Detailed Description

The yarn releasing plate of the footwear machine is shown in figure 2: the yarn placing plate comprises a yarn placing plate body 1, wherein a concave placing groove 2 is arranged in the area, corresponding to a yarn nozzle, of the yarn placing plate body 1, a lower groove 3 is arranged in the width area, corresponding to a middle yarn nozzle, of the concave placing groove 2, the periphery of the lower groove 3 is of a closed structure, the outer peripheral surface of the lower groove 3 is connected with a concave placing groove reference surface 21 through a flaring inclined surface 4 from bottom to top, and the upward guide areas, corresponding to the inclined two sides of yarns, of the lower groove 3 are in fillet transition 5.

The width surface area of the lower groove 3 covers the corresponding number of yarn nozzles of the middle area which need to have position change in the height direction;

the other end of the lower groove 3 in the length direction is a large-diameter arc profile 6 which ensures that the yarn nozzle does not generate hard contact with the boundary of the reference surface 21 of the lower groove and ensures that the abrasion is as small as possible;

the two sides of the yarn releasing plate body 1 in the width direction are respectively provided with an elongated slot positioning hole 7, and the elongated slot positioning holes 7 ensure that the yarn releasing plate body 1 is installed quickly and conveniently.

The working principle is as follows: the in-process that the yarn was passed through middle yarn mouth and is fed, the yarn upwards when outwards leading with correspond the flaring inclined plane contact that has the fillet transition owing to be face contact, and be fillet face domain for the yarn that middle zone's yarn mouth fed can not produce the closed angle friction with putting the yarn board, has improved the yarn effect of feeding, prevents anti-yarn, improves and feeds yarn stability.
