Description

Triangle device of two-way asynchronous weaving

Technical Field

The utility model relates to the field of glove knitting machines, in particular to a triangle device for bidirectional asynchronous knitting.

Background

The conventional glove knitting machine on the market has basically only two structures, namely, only has a forward needle lifting function, and only has a reverse needle lifting function for sealing. In the forward direction needle lifting process, the moving track of the needle stitch is that the needle stitch firstly rises and descends along the track surface of the rubber band needle lifting triangle, then rises to the highest point along the track surface of the forward direction needle lifting triangle, and then descends to the bottom of the forward direction density triangle along the track, so that one-way knitting of knitting rubber band firstly and then knitting yarn is completed.

The second type is that the knitting glove machine has both the forward needle lifting function and the reverse needle lifting function, and the knitting glove machine is called a jacquard glove machine or a computerized flat knitting machine in the industry. If the reverse lift is performed after the forward lift in the same knitting course, the locus of motion of the needle stitch is such that the needle stitch moves through the bottom of the rubber band density cam and then through the bottom of the reverse density cam. The mode can realize reverse needle lifting, but causes serious interference to the penetration of the elastic thread, and increases the difficulty of forward and reverse density triangle control.

The prior application CN116623353a (reference 1) discloses a cam device capable of switching between single-sided knitting, tuck knitting and bidirectional synchronous knitting, but because only one side of the cam device is provided with a rubber triangle (right side in fig. 1 and 4), when the rubber is knitted, the knitting efficiency is lower, and the rubber needle moving channel adopts the right density triangle, so that the control of the linkage of the right density triangle and the rubber triangle is needed, and the control structure is more complex.

Accordingly, the present inventors have further studied this, and developed a triangle device of two-way asynchronous knitting, which is produced by this scheme.

Disclosure of utility model

The utility model aims to provide a triangle device for bidirectional asynchronous knitting, which can improve the knitting efficiency of rubber strings and simplify a transmission structure.

a triangle device for bidirectional asynchronous knitting comprises

The elastic band needle walking device comprises a triangular bottom plate, wherein an upper middle mountain triangle and a lower middle mountain triangle are arranged on one side surface of the triangular bottom plate, density triangles are respectively arranged on two sides of the upper middle mountain triangle, elastic band auxiliary triangles are respectively arranged on the side edges of the density triangles, and elastic band triangles are respectively arranged below the elastic band auxiliary triangles, wherein the positions of the elastic band auxiliary triangles relative to the triangular bottom plate are fixed, the elastic band triangles can stretch and retract relative to the triangular bottom plate, and elastic band needle walking channels are formed by the elastic band auxiliary triangles and the elastic band triangles.

Because the needle track is different between the normal knitting and the rubber knitting, if the design mode as in the comparison document 1 is adopted, the rubber needle channel is formed by the density triangle on the right side and the rubber guide triangle, and the positions of the density triangle are different during the normal knitting and the rubber knitting, so that the movable positions of the density triangle are required to be strictly controlled.

Further, the density triangle can move up and down relative to the rubber band auxiliary triangle.

The upper and lower positions of the knitting machine can be also understood as the high and low positions relative to the rubber auxiliary triangle, and generally, when normal knitting is performed, the bottom of the density triangle is lower than the rubber auxiliary triangle, and when rubber knitting is performed, the density triangle is retracted upwards.

Further, the top of the rubber band auxiliary triangle is provided with a needle passage.

Further, the top of the rubber band auxiliary triangle is a limiting bulge, a groove is arranged below the limiting bulge, and the groove is a needle moving channel.

The limit bulge can play a role in stabilizing and limiting the needle walking of the upper butt.

Further, the side of the rubber band auxiliary triangle is also provided with a needle pressing triangle.

According to the difference of the front triangle bottom plate and the rear triangle bottom plate, the setting positions of the needle pressing triangle are different, one is relatively positioned at the left side, and the other is relatively positioned at the right side, but when the needle pressing triangle works, the front triangle bottom plate and the rear triangle bottom plate are oppositely arranged, so that the needle pressing triangle is positioned at the same side.

Further, two sides of the lower middle mountain triangle are respectively provided with a needle-together triangle.

Further, the rising action of the density triangle is realized by pushing upwards through the swing rod, and the falling action is realized by resetting the tension spring.

Further, one end of the tension spring is connected with the density triangle seat of the density triangle, and the other end of the tension spring is connected with the triangle bottom plate.

After the scheme is adopted, compared with the prior art, the utility model has the following advantages:

The needle track of the rubber band knitting is determined by the rubber band auxiliary cams, the control mode is simpler, the needle lifting of the rubber band knitting is controlled by the rubber band cams at two sides, and the knitting efficiency is higher.
