Description

A kind of two sections of degree mesh triangles of Computerized flat knitting machine

Technical field

The present invention relates to technical field of knitting machinery, specifically a kind of two sections of degree mesh triangles for Computerized flat knitting machine.

Technical background

Degree mesh triangle is an important component of computer flat-knitting machine head intermediate cam system.Pass through control when head is run The position that stepper motor processed carrys out degree of control mesh triangle can change the sinking depth of knitting needle, so that control coil size.Common degree mesh Triangle can not realize the suddenly change of sinking depth between adjacent two pin, and can only be the gradual change within the scope of certain pin number, so And adjacent two row coil size acute variation is very common in complex pattern, so limit the use scope of Computerized flat knitting machine.For Solve this problem, many Computerized flat knitting machines just using the three-legged structure of different-thickness mechanically realize adjacent windings it Between size acute variation, such triangle be referred to as two sections degree mesh triangles.Two sections of degree mesh triangles at present on country's straight-bar machines are main For fixed degree mesh triangle, that is, spending mesh triangle has certain step, but which limit the coil adjustable range of degree mesh triangle, Mesh triangle is spent simultaneously complicated, virtually add production cost.

The content of the invention

Mesh triangle is spent the invention provides the two of a kind of Computerized flat knitting machine section.

It is fixed degree mesh triangle present invention aim to address two sections of degree mesh triangles of some on existing market, that is, spends mesh Triangle has certain step, but which limit the coil adjustable range of degree mesh triangle, while spending mesh triangle complexity, nothing The problem of production cost being added in shape.

The technical solution adopted for the present invention to solve the technical problems is：A kind of two sections of degree mesh triangles of Computerized flat knitting machine, bag Include depth mesh triangle under depth mesh triangle under depth mesh trigonometric sum, the upper depth mesh trigonometric sum substantially in a rectangular trapezoid, The upper depth mesh triangle is provided with the first boss of shape in a rectangular trapezoid, and the first boss is provided with rectangular-shaped in cup head Second boss, under the bottom surface of the upper depth mesh triangle is upper depth mesh cam needle-running face, the upper depth mesh triangle The intersection point that there is right angle waist bottom surface is upper depth mesh triangle minimum point, and the lower depth mesh triangle is provided with rectangular-shaped recessed of cup head Groove, the left side of the groove is provided with right boss provided with left boss, right side, and the height of the left boss is more than right boss, it is described under The bottom surface of depth mesh triangle is lower depth mesh cam needle-running face, and the bottom surface of the lower depth mesh triangle has the intersection point of right angle waist For lower depth mesh triangle minimum point, the second boss and groove match, the bottom surface of the upper depth mesh triangle and the right side are convex Platform fits.

Further, the right angle waist of the upper depth mesh triangle is provided with inclined-plane.

Further, the height of the left boss is slightly below the upper surface of depth mesh triangle.

Further, the corner between each face is round-corner transition.

The beneficial effects of the invention are as follows：Different from traditional fixed degree mesh triangle, Computerized flat knitting machine of the present invention It can be relatively moved between the mesh triangle of degree up and down of two sections of degree mesh triangles, the coil adjustable range of degree of expanding mesh triangle, and it is tied Structure is simple, reasonable in design, greatly reduces production cost.

Embodiment

The present invention is further described with reference to the accompanying drawings and examples：

As shown in the figure there is provided the embodiment that the two of Computerized flat knitting machine of the present invention section spend mesh triangle, two sections of degree mesh triangles 2 include upper strata Mesh triangle 21 and lower depth mesh triangle 22 are spent, the upper depth mesh triangle 21 and lower depth mesh triangle 22 are substantially at right angles terraced Shape, first boss 21h of the upper depth mesh triangle 21 provided with shape in a rectangular trapezoid, the first boss 21h, which is provided with, is in The rectangular-shaped second boss 21g of cup head, the bottom surface of the upper depth mesh triangle 21 is upper depth mesh cam needle-running face 21a, The intersection point that the bottom surface of the upper depth mesh triangle 21 has right angle waist is upper depth mesh triangle minimum point 21b, the lower depth mesh Left side of the triangle 22 provided with cup head rectangular-shaped groove 22g, the groove 22g is provided with left boss 22f, right side provided with right convex Platform 22i, the left boss 22f height are more than right boss 22i, and the bottom surface of the lower depth mesh triangle 22 is lower depth mesh three Dial 22a is walked at angle, and the intersection point that the bottom surface of the lower depth mesh triangle 22 has right angle waist is lower depth mesh triangle minimum point 22b, The second boss 21g and groove 22g matches, and the bottom surface 21i and right boss 22i of the upper depth mesh triangle fit.

The right angle waist of the upper depth mesh triangle 21 is provided with inclined-plane 21c.It is easy to the heel of needle jack pin to return to initial position 21b, while the abrasion that reduction is called in person to pin.

The left boss 22f of the lower depth mesh triangle 22 is higher than plane 22h, but the upper table of slightly below upper depth mesh triangle 21 Face 21f.

Corner between each face is round-corner transition.

Its operation principle is：During work, as shown in fig. 6, two sections of degree mesh triangles 2 are slidingly disposed on mother matrix 1, motherboard The 1 linear pattern sliding rail 11,12 provided with two sections of degree mesh triangles 2, upper depth mesh triangle 21 is slided in track 11, lower depth Mesh triangle 22 is slided in track 12.As shown in Fig. 2 when depth mesh triangle is without relative slide up and down, upper depth mesh triangle 21 The dial 21a that walks overlapped with the dial 22a that walks of lower depth mesh triangle 22, the initial position 21b of upper depth mesh triangle 21 and lower floor The initial position 22b for spending mesh triangle 22 is overlapped, and can only now set single degree mesh, coil size can only be adjusted within the specific limits Section.As shown in figure 1, when up and down depth mesh triangle is relative slide when, upper depth mesh triangle 21 walks dial 21a and lower depth mesh three The initial position 22b for walking dial 22a coincidences, the initial position 21b of upper depth mesh triangle 21 and lower depth mesh triangle 22 at angle 22 Misaligned, the second boss 21g of upper depth mesh triangle 21, which is limited in the groove 22g of lower depth mesh triangle 22, to be slided, and now may be used Two sections of degree mesh are set, in the kinking stage during braiding, if pin heel is pressed downward, lower depth mesh triangle 22 are reached, It can only pass through along the initial position 21b of upper depth mesh triangle 21, form small coil；If pin heel is not pressed downward, it will edge The initial position 22b of lower depth mesh triangle 22 passes through, and forms big coil, detailed process as shown in fig. 7, wherein c1 is small coil, C2 is big coil.

Two sections of degree mesh triangles of Computerized flat knitting machine of the present invention can be controlled by program, be changed by stepper motor Difference between sinking depth and up and down depth mesh triangle.

Different from traditional fixed degree mesh triangle, the degree up and down of two sections of degree mesh triangles of Computerized flat knitting machine of the present invention It can be relatively moved between mesh triangle, the coil adjustable range of degree of expanding mesh triangle, and its is simple in construction, reasonable in design, significantly Reduce production cost.
