Description

Needle turning guide block in flat knitting machine

Technical Field

The utility model belongs to the technical field of knitting machinery, in particular to turn over needle guide block among flat-bed machine.

Background

The needle turning cam is an important part in the flat knitting machine, is arranged on a cam mother board and provides a needle turning track for knitting needles in the knitting process. As shown in fig. 5, an M-shaped needle passing track S1 is provided on the conventional stitch transferring cam, and after the knitting needle moves up to point a, the knitting needle needs to move down from point B to point C, so that the stitch transferring loop returns to the center of the needle plate opening along with the knitting needle under the action of bottom tension, and the knitting needle for receiving the stitch can smoothly pass through the loop.

In order to realize knitting, needle sending and needle receiving and releasing molding of various double-sided fabrics, a flat knitting machine adopts a multi-needle bed structure. Because the installation angle of the upper needle bed in the multi-needle bed structure is not as steep as that of the lower needle bed, the knitting needle arranged on the upper needle bed is relatively flat, so that the retreating of the overturning knitting needle can not bring the coil back to the center of the needle plate opening in the process of overturning the needle, and the step of retreating the knitting needle is not needed when the knitting needle overturns and connects with the opposite lower needle bed.

Disclosure of Invention

The utility model aims at providing a needle guide block turns over in flat-bed machine that is applicable to many needle beds structure, need not the knitting needle and returns the pine circle when turning over the needle.

Therefore, the technical scheme of the utility model is that: the needle turning guide block in the flat knitting machine is characterized in that: the needle feeding device comprises a needle turning triangle and a sliding switching triangle, wherein a trapezoidal first needle moving track is arranged on the needle turning triangle, inclined needle raising sections are arranged on two sides of the first needle moving track, a sliding groove is arranged in the middle of the first needle moving track, a baffle is arranged on the front side of the sliding groove, and a horizontal first needle moving surface is arranged above the baffle; an opening is arranged at the rear side of the sliding chute, and the sliding switching triangle is arranged on the sliding chute of the needle turning triangle through the opening and can move horizontally along the sliding chute; a convex block is arranged on the front side of the sliding switching triangle, and a second needle moving track is arranged on the convex block.

Preferably, a trapezoidal convex block is arranged on the front side of the sliding switching triangle, and the upper edge of the trapezoidal convex block is a second needle moving track and comprises second needle moving surfaces with two inclined sides and a third needle moving surface with a horizontal middle part.

The utility model discloses a needle guide block turns over comprises slip switching triangle and needle turning triangle, and the slip switching triangle can be in the spout horizontal slip of needle turning triangle top. In an initial state, the sliding switching cam is positioned at one end of the sliding groove, a knitting needle moves upwards to the first needle running surface along the lower edge of the needle raising section at one side of the needle transferring cam, the knitting needle pushes the sliding switching cam to move to the other end of the sliding groove along the first needle running surface, the knitting needle continues to move upwards and horizontally along the second needle running track of the switching cam after the sliding switching cam is abutted against the end part of the sliding groove, and finally the knitting needle moves downwards along the upper edge of the needle raising section at the other side of the needle transferring cam, so that the step of returning the turning knitting needle in the prior art is omitted, and the work efficiency is improved after the needle running track of the turning needle.

Turn over needle guide block and be applicable to the flat-bed machine of many needle beds structure, the needle guide block that turns over of going to the needle bed adopts the components of a whole that can function independently structure, slidable slide switch triangle about the track upper end becomes, when the aircraft nose moves from side to side, all can promote slide switch triangle, accomplish and turn over needle work, the commonality is strong.

Labeled as: the needle turning cam 1, the needle raising section 11, the lower edge 111, the upper edge 112, the slide rail 12, the square chute 13, the first needle running surface 14, the sliding switching cam 2, the bump 21, the second needle running surface 22 and the third needle running surface 23.

Detailed Description

See the drawings. The needle turning guide block comprises a needle turning cam 1 and a sliding switching cam 2, wherein a trapezoidal first needle moving track is arranged on the needle turning cam 1, inclined needle raising sections 11 are arranged on two sides of the first needle moving track, a knitting needle moves along the lower edge 111 of the needle raising section on one side when the needle moves upwards, the knitting needle moves along the upper edge 112 of the needle raising section on the other side when the needle moves downwards, a horizontally arranged sliding groove 12 is arranged in the middle of the first needle moving track, a baffle is arranged on the front side of the sliding rail, and a horizontal first needle moving surface 14 is arranged above the baffle; the spout rear side is equipped with a square opening 13, and slide switching triangle 2 can follow spout 12 translation on arranging spout 12 in through triangular square opening 13 of needle turning over, and when needle turning over triangle installed the triangle mother board, the triangle mother board can prevent that slide switching triangle 2 from deviating from square opening part. The front side of the sliding switching triangle is provided with a projection 21 with a trapezoidal structure, the upper edge of the projection 21 is a trapezoidal second needle passing track, and the projection comprises second needle passing surfaces 22 with two inclined sides and a third needle passing surface 23 with a horizontal middle part.

When the machine head moves to the right, the knitting needle moves to the left, and the needle moving track is S2:

in an initial state, the sliding switching cam 2 is positioned at the right end of the sliding chute 12, after a knitting needle ascends to a point A 'from the lower edge 111 of the needle raising section 11 on the right side of the needle transferring cam 1, the knitting needle starts to move along the first needle running surface 14 and pushes the sliding switching cam 2 to advance, the knitting needle starts to ascend and translate along the second needle running track on the sliding switching cam moving 2 at the point B' along the left end of the sliding chute 12 along with the movement of the sliding switching cam 2, and finally the knitting needle descends along the upper edge 112 of the needle raising section on the left side of the needle transferring cam, so that the descending B-C section in the prior art is omitted, and the working efficiency is improved after the needle running track of the needle is changed.
