Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of circular knitting machine, especially to an upper disc needleless jacquard structure of upper and lower disc circular knitting machine. BACKGROUND

[0002] The circular knitting machine is a common textile equipment. The common circular knitting machine controls the pattern of knitting by three kinds of cam tracks, namely loop forming cam track, tuck cam track and float cam track, and knits different patterns by disassembling and arranging the three kinds of cam tracks. The two-station jacquard upper disc of the common double-face jacquard circular knitting machine controls the knitting needle heel along the special cam track through the needle selector, jacquard piece and intermediate needle, and cooperates with the two-station or three-station of the lower loop to realize the computer control of knitting different pattern organizations. The two-station jacquard upper disc of the common double-face jacquard circular knitting machine has a relatively long radial length of the jacquard piece plus the intermediate needle plus the knitting needle due to the existence of the intermediate needle, which results in a relatively large radial elastic deformation and resistance. In order to prevent the elastic deformation from causing the needle to be wrong, the speed of the machine is relatively low. Moreover, the length and weight of the needle disc are relatively large, the rotational inertia is large, which is not conducive to starting and stopping the machine, and the energy consumption is relatively high.

In addition, in the description of the utility model, "a plurality of" means two or more, unless otherwise explicitly specified and limited.

[0034] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements or the interaction relationship between two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0035] As shown in FIG. 1, Figures 1 to 18 The utility model discloses an upper disc without needle lifting jacquard structure of upper and lower disc jacquard large circular knitting machine, it includes upper disc needle selection seat 1, needle selection ware seat 2, needle selection ware 3, upper disc cam seat 4, upper disc jack cam 5, upper disc needle receiving cam 6, upper disc limiting cam 7, upper disc reset cam 8, upper disc knitting cam 9, upper disc knitting presser cam 10, dial 11, upper disc jacquard group 12, upper disc knitting needle 13 and middle 14.

[0036] Upper disc needle selection seat 1 is locked with middle 14 with M8 cylinder head inner hexagon screw. Needle selection ware seat 2 is fixed to upper disc needle selection seat 1, is fixedly connected with M6 cylinder head inner hexagon screw, and the side surface of needle selection ware seat 2 is connected with needle selection ware 3, which is locked with M6 cylinder head inner hexagon screw. The lower end of upper disc needle selection seat 1 is provided with mounting hole position, and upper disc jack cam 5 and upper disc needle receiving cam 6 are fixed respectively with M4 cylinder head inner hexagon screw. The right end surface of upper disc needle selection seat 1 is provided with mounting hole, and is locked on upper disc cam seat 4 with M6 cylinder head inner hexagon screw. The lower side of upper disc cam seat 4 is provided with mounting hole position, and upper disc knitting cam 9 and upper disc knitting presser cam 10 are fixedly connected with M4 cylinder head inner hexagon screw. Dial 11 is installed below upper disc knitting cam 9, and the gap is about 0.2 millimeters, dial 11 has needle groove, jack half needle cam and jack cam, upper disc jacquard group 12 and upper disc knitting needle 13 are installed in needle groove and located on jack half needle cam and jack cam.

[0037] The conventional two-station upper disc jacquard mechanism is composed of jacquard pieces, intermediate needles and knitting needles. The key of the present application is to combine the intermediate needles and the jacquard pieces to realize the two-station upper disc jacquard function without intermediate needles. The upper disc jacquard group 12 is composed of 8 or 10 jacquard pieces. Each upper disc jacquard group 12 has a plurality of selection needle butts 12A arranged in sequence and at intervals. The plurality of selection needle butts 12A are arranged at different positions of different jacquard pieces. The plurality of jacquard pieces in the upper disc jacquard group 12 correspond to the plurality of selection needle pieces of the selection needle holder 3 respectively. The plurality of upper disc jacquard groups 12 are cyclically embedded in the needle grooves of the needle disc 11. Each jacquard piece in the upper disc jacquard group 12 has a selection needle butt 12A arranged at intervals, a top needle butt 12B and a reset needle butt 12C. The selection needle butt 12A is arranged between the reset needle butt 12C and the top needle butt 12B. One side of the top needle butt 12B forms a reset fulcrum 12D.

[0038] The upper disc knitting needle 13 has a knitting needle butt 13A, a needle hook 13B and a needle tongue 13C. When the needle disc 11 rotates, the knitting needle butt 13A will follow the cam tracks of the upper disc knitting cam 9 and the upper disc knitting presser cam 10 to realize the radial reciprocating motion in the needle groove of the needle disc 11. The track shape in the upper disc knitting cam 9 and the upper disc knitting presser cam 10 determines the three kinds of motion strokes of the upper disc knitting needle 13 relative to the cylinder mouth and the three corresponding knitting stitches, i.e. the flat needle position corresponds to the float stitch, the half needle position corresponds to the tuck stitch and the needle lifting position corresponds to the loop forming stitch. When the knitting needle butt 13A of the upper disc knitting needle 13 pushes the needle hook 13B to the highest point along the needle butt track, the needle tongue 13C is opened and the loop is separated from the needle tongue 13C. The needle hook 13B is off the loop and hooks the new loop to complete a loop forming action. When the knitting needle butt 13A pushes the needle hook 13B to half the height along the needle butt track, the needle tongue 13C is opened but the loop does not separate from the needle tongue 13C. The needle hook 13B does not off the loop and hooks the new loop to make the new and old loops knit together to complete a tuck action. When the knitting needle butt 13A follows the straight needle butt track, the needle hook 13B does not off the loop and does not hook the new loop. The needle hook completes a float action.

[0039] The selection needle holder 3, the upper disc selection needle seat 1, the upper disc top needle cam 5, the upper disc tuck cam 6 and the upper disc jacquard group 12 form a selection needle reset mechanism. The selection needle reset mechanism mainly controls the motion of the jacquard piece along different top needle tracks and the reset after the selection action. The upper disc cam seat 4, the upper disc knitting cam 9, the upper disc knitting presser cam 10 and the upper disc knitting needle 13 form a knitting mechanism. The knitting mechanism is mainly controlled by the jacquard piece to determine whether the upper disc knitting needle 13 is lifted to form a loop or tuck or is retracted.

[0040] Through the cooperation of the selection needle reset mechanism and the knitting mechanism, the three kinds of motion modes of each upper disc knitting needle 13 can be freely controlled to realize the float, tuck and loop forming stitches.

[0041] AsFigure 10 and Figure 11 As shown, each jacquard piece of the upper jacquard group 12 and the upper knitting needle 13 are in the initial state, that is, the state after being reset. Each knitting cycle starts from the initial state.

[0042] like Figure 12 and Figure 13 As shown, this is a schematic diagram of the floating yarn principle of this utility model. When the needle selector 3 is activated, it presses the needle selector heel 12A of the jacquard piece into the needle plate 11. The upper plate top needle triangle 5 loses its function, and the jacquard piece cannot push out the upper plate knitting needle 13. The upper plate knitting needle 13 moves along the floating yarn track.

[0043] like Figure 14 and Figure 15 As shown, this is a schematic diagram of the tucking principle of this utility model. The needle selector 3 is not moving. The needle heel 12B of the jacquard piece moves along the needle half-needle track of the needle plate 11. The jacquard piece pushes out the upper knitting needle 13, completing the tucking action.

[0044] Figure 16 and Figure 17 As shown, this is a schematic diagram of the loop-forming principle of this utility model. The needle selector 3 is not moving. The needle heel 12A of the jacquard piece moves along the needle track of the needle plate 11. The jacquard piece pushes out the upper knitting needle 13, completing the loop-forming action.

[0045] like Figure 18 The diagram shown is a schematic diagram of the reset principle of this utility model. During reset, the needle plate 11, jacquard piece 12 and upper plate knitting needle 13 rotate counterclockwise. The needle selector 3 presses the jacquard piece 12 into the needle plate 11. The reset fulcrum 12D of the jacquard piece 12 is lifted by the upper plate reset triangle 8. The jacquard piece 12 completes the reset action. After the jacquard piece 12 and the upper plate knitting needle 13 are reset, they return to the initial state. This cycle repeats continuously.

[0046] This utility model of a circular knitting machine with upper and lower discs features a jacquard structure without needle joints on the upper disc. Through the jacquard pieces installed in the needle grooves of the needle disc and the upper disc knitting needles, the top needle half-needle triangles of the needle disc can complete the knitting or floating yarn action. The top needle triangles of the needle disc can complete both the knitting and floating yarn action. Through the arrangement and combination of these two top needle triangles, combined with the needle selector 3 and the jacquard function of the lower disc, knitted products with jacquard on both sides can be knitted.

[0047] The above embodiments and illustrations are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
