The specific embodiment
Ask for an interview Fig. 1, pair of guide rails frame 21 peaces are solid on the head 22 of flat machine, the bottom of each guide rail bracket 21 offers guiding straight trough 8 respectively, and also integrally be formed with on the pair of guide rails frame 21 and be used for the chute 42 that the confession draw runner holds, the two ends of draw runner 9 are contained in the chute 42 respectively slidably, and engaging tooth 12 is established and is processed with in the expansion of the middle part of draw runner 9, at draw runner 9 two ends offer spacing film trap 41 corresponding to the notch position of chute 42, be provided with banking stop 40 corresponding to spacing film trap 41 positions, specifically be banking stop 40 is fixing with guide rail bracket 21 with screw 23, like this, the left side of draw runner 9, the amplitude that moves right just obtains and can rationally control.Stepper motor work when the draw runner actuation mechanism, drive transition gear 17 by driving gear 16,, therefore drive reduction gearing 14 by the rotation of transition gear 17 because transition gear 17 is coaxial with reduction gearing 14, match with engaging tooth 12 owing to reduction gearing 14 again, therefore drive draw runner 9 by reduction gearing 14 and move, draw runner 9 moves right, then reduction gearing 14 conrotatorys, otherwise, then contrary revolving, in view of this as can be known, stepper motor 15 is a clockwise and anticlockwise motor.
A pair of heel guide rail plate 34 is individually fixed on the guide rail bracket 21 by hold-down screw 39, along with sheet heel guide rail plate 34 is fixed to guide rail bracket 21, then by it chute 42 lids protected.Sheet heel guide rail 2 is fixed on the portion on the lower side of sheet heel guide rail plate 34 by screw 32, the sheet heel groove 33 that is formed on the sheet heel guide rail plate 34 is the guide grooves that move as the sheet heel row for sinker 7, and the vacancy position between the whole piece sheet heel groove 33 is connected by 35 compensation of sheet heel guiding block or title, the top of sheet heel guiding block 35 is formed with pilot pin seat 37, extend pilot pin 38 on the pilot pin seat 37, pilot pin 38 after passing through guiding translot 11, pass through and to the guiding straight trough 8 in.So, when draw runner 9 displacement to the left and right, can make sheet heel guiding block 35 do upper and lower displacement, thereby make sheet 6 downlink or uplinks of calling in person by pilot pin 38 with the altitude range that is opened in the chute 36 on the sheet heel guide rail plate 34.The former can obtain understanding by mentioned two groups of sheets heel guiding blocks 35 by diagram, promptly is provided with one group on each sheet heel guide rail plate 34, and that sheet heel guide rail plate 34 has is a pair of, so sheet heel guiding block 35 has two groups, and every group has a pair of.
Please continue to see Fig. 1 and in conjunction with Fig. 2, Fig. 3, be inserted with knitting needle inserted sheet 5 on the needle-bar 4 that provides, be provided with tooth form piece 7 at bead position, the bottom of needle-bar 4, this tooth form piece 7 is referred to as needle-bar grid sheet again, and each knitting needle 46 (Fig. 2 shows) is equipped with one piece of knitting needle inserted sheet 5.
Be arranged on the top of knitting needle inserted sheet 5 by Connection Block 30, inserted sheet pressing plate 31 as the sinker bar 1 of yarn pressing mechanism of the present utility model.Plug one piece of sinker 3 in each sedimentation film trap 24 on sinker bar 1.On sinker bar 1, be equipped with first, second spacing steel wire 20,27 and positioning wire 29, the self-evident effect of these three steel wires be sinker 3 is carried out fixed, spacing.Wherein, the first spacing steel wire 20 and positioning wire 29 are in the same side, and the first spacing steel wire 20 is last, and positioning wire 29 is descending, and both are parallel.3 of sinkers towards a side of sheet heel 6 and on the lower side portion be concaved with a pair of first, second stopper slot 43,44, when sinker 3 is pressing down in the process, first groove 43 slips over positioning wire 29, and at this moment, sinker 3 lifts, being convenient to do line ball prepares, and when sinker 3 was depressed, second groove 44 slided to the state that matches with positioning wire 29, and this moment, sinker 3 fell, push down woven stitch, promptly push down yarn coil.First, second spacing steel wire 20,27 carries out spacing respectively to sinker 3 forward and backward, the structure of the sinker 3 that provides from figure as can be known, it is whippy, this flexible embodiment be by 3 of sinkers dorsad the extended elastic foot 26 of a side of sheet heel 6 obtain, elastic foot 26 pastes mutually with filler rod 25 and touches, only its on the lower side portion make it be able at 45 positions, crescent chamber contact because of being concaved with a banana-shaped chamber or claim crescent chamber 45 substantially with the second spacing steel wire 27.The applicant is to first on the sinker 3, second groove 43,44 and the chosen position in crescent chamber 45 be according to resulting in the movement locus of sinker 3, can guarantee that sinker 3 is in elastic stage in whole motion process, concrete reason is, when sheet heel 6 presses down, first of sinker 3, second groove 43,44 and the cooperation that adds the crescent chamber 45 of elastic foot 26 can make the movement locus of sheet pin 28 produce the motion mode that includes tracing pattern, so guaranteeing under the same machining accuracy condition, make the movement locus of sinker 3 stable, phenomenon is become flexible in the front and back of having avoided being occurred by the deviation of machining accuracy, and the validity that makes sinker 3 press down coil obtains ultimate attainment performance.
Known to general knowledge, as a flat machine, have corresponding knitting needle 46 and knitting needle inserted sheet 5 and sinker 3 according to different specification (pin number), therefore, installation for the sinker of the present utility model 3 of many quantity should be identical, and action principle is consistent.And then as can be known, first, second spacing steel wire 20,27, positioning wire 29 are fixed, spacing at all sinkers 3 of being located on one piece of needle-bar 4.More and as can be known, although the applicant only chats in Fig. 1 to Fig. 3 and with respect to a casing pressure yarn mechanism required on one piece of needle-bar 4, therefore also should there be same thread depressing mechanism to bring obstacle in the understanding to another piece needle-bar 4 but can't cause, that is to say, as a flat machine, need be by two cover thread depressing mechanisms disclosed in the utility model.
Because the The Knitting Principle of flat machine belongs to known technology, so the applicant no longer illustrated The Knitting Principle, and is that motion process is sketched to the mechanism of sinker 3 only.Stepper motor 15 drives driving gear 16, because driving gear 16 is meshed with transition gear 17, because transition gear 17 is coaxial with reduction gearing 14, promptly all on axle 18, constitutes duplicate gear, thereby make draw runner 9 moving linearlies again by reduction gearing 14.Because the guiding translot of offering on the draw runner 9 11 is step slot, therefore can make pilot pin 38 do upper and lower moving along the step-like guiding translot 11 of draw runner 9, thereby drive sheet heel guiding block 35 by pilot pin seat 37 and do upper and lower motion, reach the purpose of the sheet heel 6 that acts on sinker 3.By Fig. 1 to Fig. 3 as can be known, when the head 22 of flat machine moves from right to left, draw runner 9 is motion from left to right just, stepper motor 15 under this state shows as and clockwise rotates, and reduction gearing 14 is for rotating counterclockwise, also be that stepper motor 15 is and draw runner 9 equidirectional motions, under this motion state, the the 2nd, the 4th piece of sheet heel guiding block 35 corresponding to the number from left to right in four pieces of sheets heel guiding blocks 35 of sheet heel groove 33 positions just upwards lifts, thereby the sheet heel 6 of sinker 3 is lifted and withdrawed from trim ring by the 2nd, the 4th piece of sheet heel guiding block 35; Otherwise when head moved from left to right, draw runner 9 is motion from right to left just, and the 1st, the 3rd piece of sheet heel guiding block 35 in four pieces of sheets heel guiding block 35 just upwards lifted, and made to lift in the pin heel 6 of sinker 3 and withdraw from trim ring.
