Abstract

The utility model discloses a middle-hill cam of a computer flat knitting machine. The shape of the middle-hill cam is as follows: two isosceles trapezoids are overlaid, the lower bottom of the upper trapezoid is longer that the upper bottom of the lower trapezoid, two angles are formed at the connecting part, and a reversed 'V'-shaped track between the two angles penetrates through the middle-hill cam. An 'M'-shaped track is arranged under the reversed 'V'-shaped track, and a first plane which is concave inwards is arranged under the 'M'-shaped track. Two sides of the first plane are respectively transitioned outwards from one oblique plane to one plane connected with the side edge. A middle-hill cam base is arranged under the first plane, and the center of the base is provided with a cam bulge to the first plane. Compared with the prior art, the middle-hill cam of the computer flat knitting machine can remove a large quantity of electromagnets, an electrical controlling device and a mechanical auxiliary device, simplifies the structure of a machine head, reduces the weight of the machine head, and cannot generate the phenomenon that the cam is locked or is not flexible and the like; the use of equipment is more stable and saves more energy, and the manufacture cost and the use cost are fundamentally reduced.

Description

Mountain triangle in the computer flat knitting machine

Technical field

The utility model belongs to technical field of knitting machinery, relates in particular to mountain triangle in a kind of computer flat knitting machine.

Background technology

Middle mountain triangle is an important component part in the computer flat knitting machine head.The most of working method of suitching type up and down that adopts of middle mountain triangle in the present homemade computer flat knitting machine system for weaving.When braiding flower type; In the mountain triangle all auxiliary body flexibly must be arranged, and under the control of electromagnet or other similar electric control gear cooperate, just can accomplish, therefore; Can cause final global design quite complicated in this case, also can increase manufacturing cost and installation difficulty simultaneously.In addition, triangle device is in operation, owing to hair ash, greasy dirt, automatically controlled malfunctioning or other factors; Insensitive even stuck phenomenon when also regular meeting causes this type of action triangle work; Increase fault rate, caused the damage of a large amount of knitting needles, directly influenced user's economic benefit.

Summary of the invention

The utility model aims to provide mountain triangle in a kind of computer flat knitting machine that can effectively address the above problem.

For this reason; The technical scheme of the utility model is such: the mountain triangle is two isosceles trapezoid stacks in the computer flat knitting machine; The upper base more trapezoidal than the bottom of going to the bottom that top is trapezoidal is long, forms two angles in the coupling part, and mountain triangle in the perforation of one " ∧ " shape track is arranged between two angles; One " M " shape track is arranged under " ∧ " shape track, first plane of indent is arranged under " M " shape track, each outwards transits to a plane that is connected with side by an inclined-plane both sides, first plane; First plane is middle mountain triangle base down, and the base center has on triangle projection to the first plane.

The utility model merges into a single whole butterfly mountain and middle mountain guide block, and wherein " ∧ " row track is the track that takes the needle that minute hand is in its stitch of woven condition, and " M " shape track is the track that takes the needle that minute hand is in its stitch when connecing the needle-like attitude.

When the utility model moves at Nose Left, the minute hand stitch is got into from a side of " ∧ " shape track, and rise until the position of braiding along " ∧ " shape track, the opposite side along " ∧ " shape track after the execution glides until withdrawing from " ∧ " shape track.

In addition, when Nose Left moves, also can make the minute hand stitch get into " M " shape track, though under the acting in conjunction of the triangle on first plane and first plane minute hand stitch location be equipped with squint, also can make the minute hand stitch get into " M " shape track smoothly.

When the utility model moved at Airplane Nose Right, its operation principle was identical when moving with Nose Left.

Compared with prior art; The utility model can remove a large amount of electromagnet and electric control gear, assist, has simplified the structure of head, has reduced the weight of head; Phenomenons such as triangle is stuck or dumb also can not appear; And make the use of equipment stable, more energy-conservation more, fundamentally reduce manufacturing cost and use cost, even improved the weave effect of equipment to a certain extent.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explain.

Fig. 1 is the utility model sketch map.

The specific embodiment

Referring to Fig. 1, middle mountain triangle 1 is connected to form for two isosceles trapezoids up and down, two trapezoidal junctions form have between 2, two angles 2, angle one " ∧ " shape track pass through 3 logical in mountain triangles 1, " ∧ " row track 3 is in the track that takes the needle of its stitch of woven condition for minute hand; One " M " shape track 4 is arranged, the track that takes the needle of its stitch when " M " shape track 4 connects the needle-like attitude for minute hand is under " ∧ " shape track 3; " M " shape track has first plane 5 of indent for 4 times; The left side on first plane 5 outwards transits to second plane 7 by first inclined-plane 6; Second plane 7 links to each other with middle mountain triangle 1 left side; The right side on first plane 5 outwards transits to 9, the three planes 9, the 3rd plane by second inclined-plane 8 and links to each other with middle mountain triangle 1 right edge; First plane is for 5 times a middle mountain triangle base 10, and the base center has on a triangle projection 11 to first planes.

When the utility model moves at Nose Left; The minute hand stitch is got into from a side of " ∧ " shape track 3; And rise until the position of braiding along " ∧ " shape track 3, the opposite side along " ∧ " shape track 3 after the execution glides until withdrawing from " ∧ " shape track 3.

In addition; When Nose Left moves; Also can make the minute hand stitch get into " M " shape track 4, though under the acting in conjunction of the triangle projection 11 on first plane 5 and first plane 5 the minute hand stitch location be equipped with squint, also can make the minute hand stitch get into " M " shape track 4 smoothly.

Claims

1. mountain triangle in the computer flat knitting machine; It is characterized in that: the mountain triangle is two isosceles trapezoid stacks in described; The upper base more trapezoidal than the bottom of going to the bottom that top is trapezoidal is long, forms two angles in the coupling part, and mountain triangle in the perforation of one " ∧ " shape track is arranged between two angles; One " M " shape track is arranged under " ∧ " shape track, first plane of indent is arranged under " M " shape track, each outwards transits to a plane that is connected with side by an inclined-plane both sides, first plane; First plane is middle mountain triangle base down, and the base center has on triangle projection to the first plane.
