Description

Disk mountain in flat knitting machine

Technical Field

The utility model belongs to the technical field of knitting machinery, in particular to dish mountain among the flat-bed machine.

Background

The butterfly mountain is one of important functional components of the flat knitting machine, is mainly used for pushing a lower stitch of the thimble rod to a knitting and hanging target track, can provide a needle moving track for the stitch of the thimble rod during needle receiving, and can meet the knitting, hanging target and needle receiving functions of the flat knitting machine. The existing dish mountain is shown in figure 1 and comprises a trapezoid body which is symmetrical left and right along a central vertical line, the upper edge of the trapezoid body comprises 2 same inverted V-shaped needle feeding surfaces 11, two sides of the body comprise 2 symmetrical needle raising surfaces 12, and the surface of the body comprises a concave part 13, so that the width of each inverted V-shaped needle feeding surface is smaller than that of each needle raising surface; the concave part is provided with a triangular boss 14 which is symmetrically arranged along the central vertical line of the body and integrally formed with the body. As shown in figure 2, when the machine head moves left, the needle receiving side T, the lower needle foot of the top needle rod moves along the needle moving track P1, the upper needle foot moves along the needle moving track P2, the knitting needle is driven by the top needle rod, the moving track of the knitting needle is the same as that of the top needle rod, the needle moving track P2 comprises A-B-C-D, when the top needle rod moves downwards, the upper needle foot of the top needle rod mainly depends on the upper needle foot of the top needle rod to move downwards along the track of the needle turning guide block, the lower needle foot of the top needle rod is not protected at the disc mountain, and the top needle rod can have a tendency of moving downwards. Particularly, when the machine runs fast and the machine uses a knitting needle with a large hook, a loop hooked by the needle receiving position is enlarged due to the descending of the ejector pin rod at the needle receiving position, and even fabric damage is caused.

Disclosure of Invention

The utility model aims at providing a dish mountain in flat-bed machine can protect stitch under the thimble bar to a stitch orbit of walking of operation under the thimble bar is provided.

Therefore, the technical scheme of the utility model is that: the disk mountain in the flat knitting machine comprises a bilaterally symmetrical trapezoidal body, the upper edge of the body consists of 2 inverted V-shaped needle moving surfaces, the surface of the body comprises a concave part, a triangular boss is arranged at the center of the concave part, and the two sides of the body are respectively provided with a needle moving surface; the method is characterized in that: the concave part of the body is provided with two needle moving bosses which are symmetrically arranged at two sides of the triangular boss; the upper edge of the needle moving boss comprises a first needle moving surface and a second needle moving surface, wherein the first needle moving surface is obliquely arranged, the second needle moving surface is horizontally arranged, the high-position end of the first needle moving surface is connected with the needle raising surface, and the low-position end of the first needle moving surface is connected with the second needle moving surface.

When the needle is turned over, the lower stitch of the thimble rod below the needle receiving needle moves upwards to the inverted V-shaped needle feeding surface along the triangular boss to drive the needle receiving needle to move upwards, at the moment, the needle turning over is at the highest position, and the needle receiving needle penetrates through a spring piece for needle turning over; then the lower stitch of the thimble rod below the receiving needle continuously moves upwards along the inverted V-shaped needle running surface to reach the highest position, so that the hook of the receiving needle passes through a coil on the turning knitting needle; the needle receiving knitting needle descends along the track of the needle turning guide block, and the inverted V-shaped needle running surface of the butterfly mountain can protect the lower stitch of the descending thimble rod; the needle hook top of the receiving needle is lower than the needle back of the turning knitting needle, so that the coil is lower than the latch of the turning knitting needle, and the latch of the turning knitting needle is convenient for realizing knocking over by smoothly closing the needle hook by the coil in the later driving process; and finally, the needle receiving knitting needle is parallel to the track of the needle turning guide block for a distance, the lower stitch of the lower ejector pin rod is protected by the second needle passing surface on the upper edge of the needle passing boss, and then the lower stitch of the ejector pin rod moves upwards along the first needle passing surface to drive the needle receiving knitting needle to move upwards for a section, so that the tension of a coil during knocking over is relieved, and the phenomenon that the coil cannot be stretched to form a tight fabric or the fabric is damaged due to stretching is avoided.

The utility model discloses increased the needle face of walking of thimble rod lower stitch operation on current butterfly mountain, when the needle connects, the down in-process of thimble rod, can protect lower stitch, even machine functioning speed is too fast, can not let the thimble rod down, the in-process that the knitting latch was closed is turned over in the coil area simultaneously, the first needle face of walking that the thimble rod that makes the needle joint department was gone up has been increased again, because the hook is closed, the width is the biggest this moment, in addition the needle that connects is pulling the coil downwards again, when using the knitting needle of big hook, the coil props greatly very easily, and increased this and gone up after the orbit, when turning over the knitting needle and knocking over, can alleviate coil tension, avoid the coil to prop the compactness that influences the fabric greatly, or prop brokenly the coil and cause the fabric damage.
