Abstract
The present invention provides a jacquard mechanism of a circular knitting machine, which comprises a fixed cam, a needle selecting mechanism, a movable cam which is arranged on the fixed cam and can move backwards and forwards along an established direction to form a jacquard path, and a driving mechanism which is used for driving the movable cam to move. Thus, another kind of a knitting needle moving path for plain knitting or a path for jacquard knitting is formed on the fixed cam under the condition without replacing cams for jacquard knitting by whether the movable cam moves or not, and then, a jacquard mechanism which is easy to change knitting paths is formed.
Description
The present invention relates to a kind of Special Equipment of the circular knitting machine of producing jacquard fabric, particularly a kind of circular knitting machine.
On circular knitting machine, install selecting mechanism additional, the ejection knitting needle or the sinker of selecting type, generate cloth cover by this and have looped pile, the jacquard fabric of perforate or decorative pattern, be to be the known technology of people already, and above-mentioned knitting needle or sinker be not when doing jacquard knitting at ordinary times, its knitting needle or sinker be empty needle height on triangle or the operation of knitting height normally, when needs carry out jacquard knitting, above-mentioned knitting needle or sinker must enter another different knitting height that are positioned on the triangle, in traditional technology, if require knitting another knitting height that enters, except readjusting full-jacquard mechanism (as pattern wheel), the triangle that has been installed on the circular knitting machine also need be changed, and this replacing operation has on the circular knitting machine of a lot of triangles, to change many manpowers of expense and man-hour, it is low that it changes efficient.
The objective of the invention is to provide a kind of jacquard attachment of circular knitting machine, its triangle that need not change the outfit just can provide another kind of jacquard weave path, and it also can finish the modulation operation rapidly with change jacquard weave path.
Invention is achieved in that the fixed triangle of the jacquard attachment of circular knitting machine has a ditch portion at least, with a movable triangle that is configured in the ditch portion and can in ditch portion, moves, this movable triangle can move to a higher position in ditch portion, another track that is different from aforementioned track with formation, or in ditch portion, move to another lower position, and do not form another track; Establish a drive unit on the movable triangle, arrive aforesaid higher position or lower position in order to move it, establish a servomotor in the drive unit, the output termination of servomotor is established cam, on the eccentric point of cam, articulate crank, the other end of crank is articulated in movable triangle, drives movable triangle with servomotor and moves in ditch portion, its formation of mat or do not form another above-mentioned track.
The present invention disposes one and can move back and forth along set direction and form the movable triangle of another knitting height in good time on fixed triangle, and one drive the drive unit that movable triangle moves, thereby, in the another kind of knitting height of needs, can be under the condition of not changing triangle, move above-mentioned movable triangle and obtain required knitting height at once; Drive the drive unit that movable triangle moves and form, utilize the control of computer or numerical digit, just can finish the modulation operation rapidly by a step-by-step motor and crank.
The concrete structure of invention is provided by following embodiment and accompanying drawing thereof.

Figure 11 is the profile of Figure 10 in the A-A position.
Figure 12 is the profile of Figure 10 in the B-B position.
With reference to Fig. 2,3, the jacquard attachment of circular knitting machine is formed by a fixed triangle 1, movable triangle 2 with in order to the drive unit that drives movable triangle 2.
Fixed triangle 1 is configured in the cylinder week outside of circular knitting machine and goes up any of fixing, as shown in Figure 1, at the inner face 10 of this fixed triangle 1 towards syringe, have complex trace and can embed the track of making pin or narrowing motion in order to guiding knitting needle 3 for the stitch 31 (Fig. 6) of knitting needle 3, this track includes at least: in order to knitting needle 3 is lifted to the knitting channel 4 of knitting height, with so that knitting needle 3 maintains the empty needle track 5 of empty needle height, knitting channel 4 all is a kind of wide grooves that are depressed in inner face 10 with empty needle track 5.
Characteristics of the present invention are, outside set knitting channel 4 and empty needle track 5, the one another kind of jacquard weave track that can form at once when needed is provided, be example with the tuck track that can make knitting needle 3 arrive tuck height in the present invention, the tuck track 6 (Fig. 7) of knitting needle elevate a turnable ladder to tuck height can be made of a upper limb that is disposed at the movable triangle 2 of fixed triangle 1, movable triangle 2 has at least in order to knitting needle 3 is lifted to the elevate a turnable ladder face 21 of tuck height, with make knitting needle 3 maintain the horizontal tuck face 22 of tuck height a period of time, movable triangle 2 can move to a lower position (as shown in Figure 4) that does not form tuck track 6 arbitrarily in the ditch portion 11 at fixed triangle 1 back side, or the higher position of formation tuck track 6, for guaranteeing accuracy and the grazing of movable triangle 2 when mobile, on the contact-making surface of movable triangle 2 and ditch portion 11, the protruding rail 110 that preferably is formed with recessed chase 23 respectively and protrudes, when movable triangle 2 gives rise to tuck height, elevate a turnable ladder face 21 and tuck face 22 again with fixed triangle 1 on a similar shape flange 12 keep the spacing that can pass through for stitch 31, and this banded space that equidistantly forms is exactly a tuck track 6.
With reference to Fig. 5, fixed triangle 1 and movable triangle 2 are installed in a saddle 13, saddle 13 is installed on the appropriate location on the circular loom, saddle 13 configurations one are in order to drive the drive unit that movable triangle 2 moves, drive unit includes a servomotor 8, the output termination of servomotor 8 is established a cam 80, on the eccentric point of cam 80, articulate a crank 81, the other end of crank 81 is articulated in movable triangle 2, when requiring to increase the tuck track, only need utilize the mode of computer or other numerical digits control, just can drive servomotor 8 runnings rapidly, thereby movable triangle 2 is lifted to the height that forms tuck track 6; Rotating shaft tail end at servomotor 8, set firmly a location flashboard 82, with a position detector 83, flashboard 82 two ends, location establish one can be by the fin 821,822 of position detector 83, when cam 80 every Rotate 180s °, fin 821,822 is in-position detector 83 also, and position detector 83 is photoelectric cell or other equivalence elements, so just can learn whether movable triangle 2 arrives the tram by position detector 83.
With reference to Fig. 6, when needle selection device (not shown) does not promote to rise pin push rod 7, rise the stitch 71,72 of pin push rod 7 will be not be positioned at fixed triangle 1 on knitting flange 14 or push away flange 15 and contact, the empty needle track 5 that the stitch 31 of knitting needle 3 will prolong level moves; Otherwise when the needle selection device promotes to rise pin push rod 7 and is the heeling condition of Fig. 8, the last stitch that rises pin push rod 7 will embed knitting flange 14 and rising (as Fig. 9) gradually, promote the knitting channel 4 that knitting needle 3 rises to the upper limb of flange 12 simultaneously, to carry out knitting operation; At last, when the needle selection device promotes to rise pin push rod 7 and is the heeling condition of Figure 11, the following stitch 72 that rises pin push rod 7 is with embedding push pin flange 15 and rise gradually (as Figure 12), at the same time, movable triangle 2 also will be lifted to Fig. 3 position, the stitch 31 of knitting needle 3 is just prolonging elevate a turnable ladder face 21 and tuck face 22 (Figure 10), arrives the operation of highly pushing pin of pushing pin, and finishes the jacquard weave action.
