Abstract

The utility model discloses a needle turning cam of a computerized flat knitting machine, comprising a body which is left and right symmetrical, wherein the body is provided with a top edge which is linear and a U-shaped bottom edge which is concave inwards; an M-shaped groove is arranged in the middle of the body, two ends of the M-shaped groove extend toward two sides of the body respectively and intersect with two side edges of the body to form an extended flare opening to penetrate through the body; and the part between the M-shaped groove and the bottom edge is further provided with a plurality of slopes which incline downwards from inside to outside. Compared with the prior art, the utility model can eliminate a great number of electromagnets, electric control devices and mechanical auxiliary devices, not only the structure of the machine head is simplified and the weight of the machine head is reduced, but also the phenomena of cam seizing or inflexibility and the like can not occur; and the device is stable and energy-saving in use, the manufacture cost and the use cost are fundamentally reduced, and the weaving effect of the device is improved to certain extent.

Description

Computer flat knitting machine turn over the pin triangle

Technical field

The utility model belongs to technical field of knitting machinery, and what especially relate to a kind of computer flat knitting machine turns over the pin triangle.

Background technology

Turn over the pin triangle and be an important component part in the computer flat knitting machine head.At present, the stitch track design of homemade computer flat knitting machine when turning over pin generally is by middle mountain triangle and the switching up and down of turning over the needle guide piece, match with sharp mountain by turning over the needle guide piece, thus the running rail of stitch when pin is turned in formation.When braiding during garment piece, according to the needs of flower type technology, knitting cam and turn over the switching that the pin triangle often moves, some corresponding compressing tablets also will carry out the change of position.No matter be the action of triangle or the change of compressing tablet position, all must there be auxiliary body flexibly under the control of electromagnet or other similar electric control gear cooperate, to finish.Like this, final triangle project organization will be very complicated, also can increase manufacturing cost and installation difficulty simultaneously.In addition, triangle device is when switching, owing to hair ash, greasy dirt, automatically controlled malfunctioning or other factors; also regular meeting causes the insensitive even stuck phenomenon of this type of action triangle work; both increase fault rate, also caused the damage of a large amount of crochet hooks simultaneously, directly influenced user's economic interests.

The utility model content

The utility model provide a kind of simple in structure, better effects if computer flat knitting machine turn over the pin triangle, to solve existing pin three-legged structure complexity, the problem that fault rate is high of turning over.

For this reason, the technical solution adopted in the utility model is such: computer flat knitting machine turn over the pin triangle, comprise a symmetrical body, have linearly a top margin and on the body and concave and be the base of U type; It is characterized in that: described body middle part has a M type groove, and extend to the body both sides respectively at the two ends of M type groove, and is crossing with the dual-side of body, forms the horn mouth that extends out, thereby connects body; Also have several inclined-planes on the part between M type groove and the base, the inclined-plane from-inner-to-outer is downward-sloping.

When the utility model moves at Nose Left, minute hand epimere stitch is entered by the horn mouth that is positioned at body one side, end along M type groove rises, move to and turn over the pin position, finish knocking over, turn over a series of actions such as pin, stitch can glide along the other end of M type groove afterwards, is left by the horn mouth that is positioned at the body opposite side.

Part between the utility model M type groove and the base also has several inclined-planes, the inclined-plane from-inner-to-outer is downward-sloping, so when minute hand epimere stitch is in the horn mouth below, can be subjected to the effect on inclined-plane to slip into M type groove smoothly, end along M type groove rises, and moves to enter and turns over the pin position.

The utility model moves at Airplane Nose Right, and its principle that takes the needle of turning over pin is identical when moving with Nose Left, repeats no more.

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

Description of drawings

Fig. 1 is the structural representation of present embodiment.

The dotted line of band arrow is the Cam Track of present embodiment in the accompanying drawing.

Arrow points under in the accompanying drawing is represented the traffic direction of head.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Referring to accompanying drawing, present embodiment comprises a symmetrical body 1, has the base 3 that linearly a top margin 2 and concaves and is the U type on the body 1; Described body 1 middle part has a M type groove 4, the two ends of M type groove 4 are that oblique groove extends to body 1 both sides respectively, the extension upper side at its two ends respectively be positioned at a, the b place is inclined upwardly, form first inclined-plane 13 and second inclined-plane 14, the extension on first and second inclined-

plane

13,14 dual-side outside respectively at c, d place and body 1 intersects, form two first horn mouths 5 that extend out and second horn mouth 6, thereby connect body 1, constitute the track that takes the needle.

Have first plane 9 and second plane 10 respectively between described first and second horn mouth 5,6 and the base 3, the angle that forms between first and second horn mouth 5,6 and the base 3 also has the 3rd downward-sloping inclined-plane 7 of from-inner-to-outer and the 4th inclined-plane 8 respectively, and the inner on third and fourth inclined-plane 7,8 links to each other respectively at the end of first plane 9 with second plane 10; Also respectively downward-sloping the 5th inclined-plane 11 of tool from-inner-to-outer and the other end on 12, the first planes 9, the 6th inclined-plane and second plane 10 link to each other with the 6th inclined-plane 12 with the 5th inclined-plane 11 respectively between the oblique groove at M type groove 4 two ends and the base 3.

When present embodiment moves left at head, can make minute hand epimere stitch enter the track that takes the needle by first horn mouth 5, oblique groove along M type groove 4 left sides rises, move to and turn over the pin position, finish knocking over, turn over a series of actions such as pin, the just oblique groove downslide on M type groove 4 right sides of stitch afterwards is until leaving the track that takes the needle from second horn mouth 6.

Present embodiment since the extension upper side of M type groove 4 left ends be inclined upwardly being positioned at a place, form first inclined-plane 13, so when minute hand epimere stitch is in the horn mouth top, can be subjected to the effect on first inclined-plane 13, slip into M type groove 4 smoothly, oblique groove along M type groove 4 left sides rises, and moves to enter and turns over the pin position.

Present embodiment is also because the left side and the part between the base 3 of M type groove 4 also have the 3rd inclined-plane, first plane 9 and the 5th inclined-plane 11, so when minute hand epimere stitch is in the horn mouth below, can be subjected to the effect on the 3rd inclined-plane, first plane 9 and the 5th inclined-plane 11 to slip into M type groove 4 smoothly, oblique groove along M type groove 4 left sides rises, and moves to enter and turns over the pin position.

Present embodiment moves at Airplane Nose Right, and its principle that takes the needle of turning over pin is identical when moving with Nose Left, repeats no more.
