Abstract

The utility model discloses a tuck cam for a flat knitting machine. A tuck cam comprises a main body, a cam block is positioned on the main body, and the cam block comprises a first needle passing face, a plane and a second needle passing face. The first needle passing face comprises a lifting portion and a descending portion, wherein the lifting portion and the descending portion are in arc transition connection. The plane is connected with the first needle passing face, the second needle passing face is arranged on the plane far away from the lifting portion of the first needle passing face, and an included angle between the second needle passing face and the plane is larger than 90 degrees. The tuck cam has the advantages that due to the two needle passing faces, needle selection and needle passing are slow, and needle connection is convenient.

Description

The tuck cam of flat machine

Technical field

The utility model belongs to technical field of knitting machinery, especially relates to the tuck cam of flat machine.

Background technology

The cam system of Computerized flat knitting machine is installed in the head, and along with head side-to-side movement together, needle selection moves up and down along the dial of walking of each action triangle, thereby accomplishes braid movement.The effect of tuck cam is that the guiding needle selection gets into the tuck position, in this process, how to protect tuck cam and pin bell, makes both hard collision can not take place, and is the technical problem that present technical staff faces.

The utility model content

The purpose of the utility model is for a kind of tuck cam of flat machine is provided, and its configuration design helps passing through smoothly of needle selection pin bell.

For this reason; The technical scheme that the utility model adopts is: the tuck cam of flat machine; Comprise body, it is characterized in that: have a corner block on the said body, said corner block comprise first walk dial, dial is walked on a plane and second; Said first face of taking the needle comprises riser portions and falling portion, and said riser portions is connected with the falling portion arc-shaped transition; Said plane and first is walked dial and is joined, on it away from first walk dial the riser portions place have second and walk dial, said second walks angle between dial and the said plane greater than 90 degree.

Further improvement as the utility model is: said tuck cam also has a plane of orientation, and said plane of orientation one side is connected with corner block, and opposite side is connected with backstay.

Further improvement as the utility model is: said plane of orientation has a location breach.

Adopt after the said structure, during braiding, it is up that needle selection is walked the riser portions of dial along first; Intersection up to riser portions and falling portion; The design of the arc at this place makes that the needle selection tendency is mild, not can with corner block generation hard collision, needle selection gets into next corner block thus.When connecing pin, because second to walk dial be one domatic, needle selection pin bell takes the needle when conveniently connecing pin.

The plane of orientation of the utility model has a breach, when the purpose that said breach is set is convenient the installation tuck cam is positioned.

Adopt the beneficial effect of the utility model to be: two designs of walking dial make and the needle selection mitigation that takes the needle conveniently connect pin.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.

Fig. 1 is the sketch map of the utility model.

The specific embodiment

Referring to Fig. 1.Present embodiment comprises a positioning rod 7; Plane of orientation 4 has a breach 8 on the plane of orientation 4, plane of orientation 4 one sides link to each other with backstay 7; Opposite side links to each other with corner block; Shown in corner block comprise that one first walks dial, first face of taking the needle comprises riser portions 1 and falling portion 3, riser portions 1 is connected to form tuck point 2 with falling portion 3 arc transition.Corner block also comprises a plane 5, have on the plane 5 one second walk dial 6, the second walk dial 6 be positioned at first walk dial falling portion near, and the angle between the said plane 5 greater than 90 the degree.The design of this shape makes needle selection mild through the running orbit that riser portions 1 arrives tuck point.Simultaneously, second walk dial inclined design make needle selection easily through corner block, make things convenient for needle selection pin bell to take the needle.
