The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Contrast Fig. 1, Fig. 2, in the present embodiment, rise cam is made up of two short rise cams 8 and a long rise cam 7, they place the front side in the straight trough hole 3 of support 18, be equipped with corresponding connecting plate 11,15 on the 3 rear side correspondence positions of straight trough hole respectively, screw 20 passes rise cam straight trough hole 3 rise cam is connected with corresponding connecting plate, and rise cam is slidably connected in the rise cam slotted eye 3.Two fixed reset triangles 1 are fixed in the both sides, upper end of support 18 respectively by three screws 20, two are moved the front side that the triangle 6 that resets places the triangle straight trough hole 5 that resets of 18 liang of symmetries of support respectively, on the triangle straight trough hole 5 rear side correspondence positions that reset, be equipped with corresponding connecting plate 14 respectively, screw 20 passes the triangle straight trough hole 5 that resets with above-mentioned both connections, and the mobile triangle 6 that resets is slidably connected in the triangle slotted eye 5 that resets of support upper end.
The present invention adopted move reset triangulation techniques this be that applicant is in a patent application (application number is 200420025623.6) that proposes before this, in the rear side of fixed head 10 position corresponding to breach 12, electromagnetic attracting device 16 is installed, block tongue 21 positive alignment breach 12 on it, when the mobile triangle 6 that resets is in the center in the triangle straight trough hole 5 that resets, thereafter the breach on the side connecting plate 13 is just in time aimed at above-mentioned breach 12, during electromagnetic attracting device 16 energisings, push rod 17 on it ejects, block tongue 21 is pushed and places this breach 13, the mobile triangle that resets is fixed (seen also Fig. 1, Fig. 2, Fig. 3).Rise cam 8 adopts applicant in a patent (application number the is 200310106289.7) technology that proposes before this, and the downside of promptly rabbeting on rise cam is opened a rectangular indentation, is used to rabbet magnetic block 19.In the middle of this magnetic block is the permanent magnets both sides tightly put magnetic inductive block respectively and at upper and lower side with copper sheet every magnetic, the centre is filled out with every the magnetic resin.
Apparatus of the present invention are installed on the head 23 by the installing hole 22 usefulness screws at support 18 downside two ends, the needle central portion 25 of sinker 24 interts in rise cam 8 and moves in the neutral that resets between triangle 6 or the fixed reset triangle 1, referring to Fig. 4, the spigot surface of control sinker needle central portion 25 swings is formed on the withdrawal of needle inclined-plane 31 and the inclined-plane 27 that resets.Head 23 moves to a certain position, clock pin portion 25 on the 27 pairs of sinkers 24 in inclined-plane that reset on withdrawal of needle inclined-plane 31 on the rise cam or the mobile triangle that resets pushes effect, sinker 24 is rotated relative to steel wire turning cylinder 30, thereby the pressure of 28 pairs of fabrics of line ball portion of control sinker 24 is dark.
During work, the present invention is with head 23 reciprocating motion on needle-bar 29, constantly change the direction of motion, the spigot surface of sinker needle central portion 25 also will change, the variation of this spigot surface is to utilize permanent magnet 19 on the rise cam and the starting triangle straight trough hole on the support 18 and the triangle straight trough hole that resets to realize among the present invention: when head 23 moves to end positions, need to change the direction of motion, support 18 can change the direction of motion with head immediately because of being fixed on the head, and rise cam 7,8 because of be attracted on the fixed needle-bar 29 by magneticaction, can not change the direction of motion immediately thereupon, rise cam is just moved along rise cam straight trough hole 3 backward with respect to proal support 18 like this, and drive to move the triangle that resets and move backward along the triangle straight trough hole 5 that resets, cause the withdrawal of needle inclined-plane and the inclined-plane generation conversion that resets.
See also Fig. 5, when head 23 advances to the left position of needle-bar 29, change the direction of motion, advance to the right, support 18 is with head 23 right laterals, this moment rise cam 8,7 along rise cam slotted eye 3 relative supports 18 to left movement, and short rise cam 8 in right side and middle long rise cam 7 promote right respectively by pushing surface 4 on it, two side shiftings the reset locating surface 33 of triangle 6 in a left side makes it left lateral together, the right side is moved the triangle 6 that resets and is slided to the left end of the triangle slotted eye 5 that resets and be restricted, middle long rise cam 7 slides to the center of rise cam slotted eye 3 and is restricted, short rise cam 8 left lateral in left side are restricted to rise cam straight trough hole 3 left ends, make and move the triangle 6 that resets, the motion that moves to left relatively of rise cam stops.Like this rise cam with move the triangle that resets and finish the motion of relative left lateral after, the withdrawal of needle inclined working of rise cam converts the right side to by the left side, the inclined working that resets that moves the triangle that resets also converts the right side to by the left side, has finished the conversion to the needle central portion spigot surface.In this conversion process, rise cam moving linearly, and be different from first previous crops plane motion, make motion steadily and reliability improve greatly.
Head continues right lateral, this moment rise cam, move and to reset triangle with the head right lateral, the needle central portion 25 of sinker 24 is pushed upwards the upper end 32 until rise cam under the guiding on the withdrawal of needle inclined-plane 31 of rise cam, and advance along this end face, made sinker 24 26 rotations of doing by a relatively large margin around the shaft because sinker needle central portion 25 upwards pushes, its line ball portion 28 can compress withdrawal of needle, the knocking over that fell guarantees knitting needle.Sinker needle central portion 25 inclined-plane 27 that resets up to running on the triangle that resets that continues to advance is pushed to being issued to and is resetted.
The track of the knitting needle syringe needle on the head position as shown in Figure 7, as turning over pin when the control area of long rise cam 7 when needing, see also Fig. 5, sinker does not need that the coil on interval 2 knitting needles is had compacting, so shorten control area to the sinker needle central portion, at this moment, electromagnetic attracting device 16 energisings, push rod 17 ejects, make that block tongue clockwise rotates on it (seeing also Fig. 3), correcting the embedding right side on it moves in the breach 13 of the triangle rear side that resets, the centre position that the triangle 6 that resets is fixed in the triangle slotted eye 5 that resets is moved on the right side, has shortened the stroke of needle central portion on rise cam upper end 32, and sinker clock pin portion runs into the inclined-plane falling that resets of moving the triangle that resets very soon, sinker line ball portion lifts, and coil is not had suppression.One section zone of 32 is the pneumatics district to needle central portion to the upper end by the pushing and pressing of the withdrawal of needle inclined-plane, right side of long rise cam 7, does not influence the braiding to fabric.
Fig. 6 is right end position and the working condition of commutation when advancing left that advances to needle-bar when head, the conversion on its withdrawal of needle inclined-plane and the inclined-plane that resets and sinker are the same when also commutation is advanced to the right with the left position that head advances to needle-bar to the control situation of needle central portion, repeat no more here.
When head 29 does not change the direction of motion in the two-end-point position, be that head 23 is when being in the position of the arrangement that sinker 24 is arranged on the needle-bar 29, reciprocal athletic meeting makes the inclined-plane of 25 pairs of rise cam one sides of needle central portion of sinker push effect, and the relative support 18 of rise cam is moved along rise cam straight trough hole 3.Because pin clock pushing and pressing are on an inclined-plane, and rise cam does rectilinear motion, so needle central portion is difficult for by " stuck " when pushing and pressing, rise cam is to do rectilinear motion simultaneously, the resistance of motion is less relatively, and then needle central portion is very little to the bending force that is subjected to, and " having an injection " phenomenon can not occur.
