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 in head operation The sinking depth of knitting needle can be changed in the position that stepper motor processed carrys out degree of control mesh triangle, thus control coil size.Common degree mesh Triangle cannot achieve the suddenly change of sinking depth between adjacent two needle, and can only be the gradual change within the scope of certain needle number, so And adjacent two column coil size acute variation is very common in complex pattern, so limit the use scope of Computerized flat knitting machine.For Solve the problems, such as this, many Computerized flat knitting machines just use the three-legged structure of different-thickness mechanically realize adjacent windings it Between size acute variation, such triangle is known as two sections of degree mesh triangles.Two sections of degree mesh triangles at present on country's straight-bar machines are main For fixed degree mesh triangle, i.e. degree mesh triangle has certain step, but which limit the coil adjustable range of degree mesh triangle, It is complicated that mesh triangle is spent simultaneously, virtually increases production cost.

Summary of the invention

The present invention provides a kind of two sections of degree mesh triangles of Computerized flat knitting machine.

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

The technical solution adopted by the present invention to solve the technical problems is: a kind of two sections of degree mesh triangles of Computerized flat knitting machine, packet Depth mesh triangle under depth mesh trigonometric sum is included, depth mesh triangle is substantially in a rectangular trapezoid under the upper depth mesh trigonometric sum, The upper depth mesh triangle is equipped with first boss in the shape of a right-angled ladder, and the first boss is equipped with rectangular-shaped in cup head Second boss, the bottom surface of the upper depth mesh triangle is upper depth mesh cam needle-running face, under the upper depth mesh triangle The intersection point that there is right angle waist in bottom surface is upper depth mesh triangle minimum point, and the lower depth mesh triangle is equipped with rectangular-shaped recessed of cup head Slot, the left side of the groove is equipped with left boss, right side is equipped with right boss, and the height of the left boss is greater than right boss, under described 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 matches with groove, and 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 equipped with inclined-plane.

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

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

The beneficial effects of the present invention are: it is 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, design is reasonable, greatly reduces production cost.

Specific embodiment

Present invention will be further explained below with reference to the attached drawings and examples:

As shown, providing the embodiment of two sections of degree mesh triangles of Computerized flat knitting machine of the present invention, two sections of degree mesh triangles 2 include Upper depth mesh triangle 21 and lower depth mesh triangle 22, the upper depth mesh triangle 21 and lower depth mesh triangle 22 are substantially at right angles Trapezoidal, the upper depth mesh triangle 21 is equipped with first boss 21h in the shape of a right-angled ladder, and the first boss 21h is equipped with In the second boss 21g that cup head is rectangular-shaped, 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 are upper depth mesh triangle minimum point 21b, the lower layer The left side that degree mesh triangle 22 is equipped with rectangular-shaped the groove 22g, the groove 22g of cup head is equipped with left boss 22f, right side is equipped with The height of right boss 22i, the left boss 22f are greater than right boss 22i, and the bottom surface of the lower depth mesh triangle 22 is lower depth Mesh cam needle-running face 22a, the intersection point that the bottom surface of the lower depth mesh triangle 22 has right angle waist are lower depth mesh triangle minimum point 22b, the second boss 21g and groove 22g match, and the bottom surface 21i and right boss 22i of the upper depth mesh triangle are affixed It closes.

The right angle waist of the upper depth mesh triangle 21 is equipped with inclined-plane 21c.It returns to initial position convenient for the heel of needle jack needle 21b, while reducing the abrasion called in person to needle.

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 working principle is that: when work, as shown in fig. 6, two sections of degree mesh triangles 2 are slidingly disposed on mother matrix 1, motherboard 1 is equipped with the linear type sliding rail 11,12 of two sections of degree mesh triangles 2, and upper depth mesh triangle 21 slides in track 11, lower depth Mesh triangle 22 slides in track 12.As shown in Fig. 2, when upper and lower depth mesh triangle is without opposite sliding, upper depth mesh triangle 21 The dial 21a that walks be 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 layer The initial position 22b for spending mesh triangle 22 is overlapped, and single degree mesh can only be arranged at this time, coil size can only be adjusted in a certain range Section.As shown in Figure 1, upper depth mesh triangle 21 walks dial 21a and lower depth mesh three when upper and lower depth mesh triangle slides relatively Walk dial 22a coincidence, the initial position 22b of the initial position 21b of upper depth mesh triangle 21 and lower depth mesh triangle 22 in angle 22 It is not overlapped, the second boss 21g of upper depth mesh triangle 21 is limited in sliding in the groove 22g of lower depth mesh triangle 22, at this time may be used Two sections of degree mesh are set, the kinking stage in the weaving process then reaches lower depth mesh triangle 22 if gynophore heel is pressed downward, It can only pass through along the initial position 21b of upper depth mesh triangle 21, form small coil；If gynophore 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 be 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 upper and lower 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 simple structure and reasonable design, significantly Reduce production cost.
