Description

The sinker of circular cyiinder knitting machine and the improvement of shanjiao rail structure thereof

The present invention is relevant a kind of circular cyiinder knitting machine improved structure, especially refer to a kind of composition surface that most acting surfaces are provided between sinker and shanjiao rail thereof that makes, with effective enhancing sinker meeting with stresses in its reciprocating stroke action, to solve living gram shanjiao rail the sinker applied stress is crossed the drawback that what is concentrated single composition surface, thereby the improvement constructor who significantly improves sinker and shanjiao rail thereof.

As is generally known, sinker Department and knitting needle Zhong knitting process cooperatively interact, so that yarn is interweaved, move back circle, kinking, band yarn, lasso and knocking over etc. and reach, each yarn circle of single yarn is interweaved link together and goes here and there the knitwear that are made into our institute's phase.

By the knitting operation process of generally commonly using, living gram single-side machine is when braiding, and it goes out pin, the timely distance of narrowing and all promotes knitting needle and restrain shanjiao rail promotion sinker (sinker) and reach the weave effect person of the yarn by giving birth in backer angle (cam).With regard to its operating principle, the equal orthogonal motion mode of Mining between the Shengke ring of living gram single-side machine and syringe, Yin Shengke sheet Department to running, just in time are vertical interaction with the vertical of knitting needle to action with level mutually.Easy speech, the cycle that goes out pin (knocking over) and narrowing (lopping) of knitting needle should cooperatively interact with the horizontal reciprocating movement cycle of sinker, just can make yarn reach the purpose of braiding, the groove of sinker bears and gives birth to the gram shanjiao rail with sizable stress in running up around here, make the acting surface damaged phenomenon of giving birth to the gram groove that shanjiao rail acted on quite frequent, the loop-forming sinker in knitting machine and the action between shanjiao rail thereof that cooperate Fig. 1 to 3 to commonly use are now again closed the Department detailed description as follows:

Known circular cyiinder knitting machine structure, as shown in Figure 1, comprise angle, mountain seat ring 10, establish angle, mountain seat 11 on it, seat top in angle, mountain is established angle, sinker mountain seat 12 again, and the below of angle, sinker mountain seat 12 is established and given birth to gram tube 13 and give birth to gram shanjiao rail 14, what is given birth to gram tube 13 and is given birth to 14 folders of gram shanjiao rail and establish sinker 15, the circumferential outer edge relative with angle, the mountain seat 11 of knitting needle established syringe 16, and in order to the running of control knitting needle 17, the top of knitting needle 17 is provided with

Yarn chews 18, as seen from the figure, sinker 15 Department cards establish that what is given birth to gram shanjiao rail 14 and with knitting needle 17 reciprocations to go the weaving operation of yarn.

Now the knitting needle and the sinker action Guan Department between the two that consult in the knitting process that Fig. 2 just commonly uses illustrate it in detail again, when knitting needle rises to peak, as Fig. 2 A(1) shown in position Wu Ren Department utilize sinker to push down the yarn circle, make the complete knocking over sinker of yarn circle on the knitting needle then be pushed into the forefront, shown in the 1st of Fig. 2 B by living Keshan angle 150; When sinker is subjected to the effect at angle, mountain 150, shown in the 2nd position of Fig. 2 B, begin to retreat, just knitting needle 17 is prepared toward descending, shown in arrow B2, to go the hook yarn; When knitting needle continues down to reduce as far as possible and sinker is subjected to the effect at angle, mountain 150, also retreat to towards external position, and form new yarn circle, as Fig. 2 A(3) and the 3rd position of 2B shown in; After the yarn circle formed, before knitting needle did not rise, sinker must be pushed into the position, forefront earlier ahead of time, and utilizes sinker to compress the yarn circle, cannot not make it floatingly.As Fig. 2 A(4) and the 4th position of 2B shown in; Knitting needle continues toward rising to go knocking at this moment, and with till complete knocking over, and this moment, sinker also maintained going-back position, shown in Fig. 2 (5) and (6) and the 5th position of Fig. 2 B, just action so again and again is known knitting whole process.

As shown in the above description, dual-side 141 that two inner side edges 151 of the shanjiao rail effect groove 150 of sinker 15 and 152 Department are subjected to shanjiao rail 14 fully respectively shown in Fig. 3 A to 3D and 142 reciprocating motion and in angle, mountain seat 12, advance and retreat, this reciprocating number of times that advances and retreat still improves with the quickening of the knitting board running speed of work, compete day by day according to strong by the what hosiery trade, the dealer is under raising successively on direct labor cost and the cost of material, meet again under the dual impact of finished product price landing day by day, all manage to do one's utmost to improve and produce, phase makes identical artificial reaching under the equipment increases output, improve row yielding, to reduce production costs, in the hope of living space, so the dealer just manages to increase on knitting machine Yarn mouth number and raising running speed, just the problem that becomes the dealer for the moment and earnestly chased, yet known to practice and theory, the former is subjected to the restriction in space, different difficult the breakthrough, the latter then is subjected to knitting machine, and abrasion, the especially sinker of part are subjected to the stress impact effect maximum of shanjiao rail in addition, for example, total with the big knitting machine of 30 inch diameters

Yarn mouth number is 150 mouthfuls of numbers, RPM is 20, then every day, knitting needle was with 24 hours running, the reciprocating number of times of every every day of sinker is 24 * 60 * 20 * 150=4,320,000 time, and the thickness of sinker is 0.2～0.25mm, go through 4 in every day, 320, work under 000 time the frequency, 151 limits of the groove 150 of sinker 15 are the 141 limits effect of sinker shanjiao rail 14, in like manner its 152 limit is acted on by 142 limits of sinker shanjiao rail 14, that is, two inner side edges 151 of the groove 150 of sinker, 152, need bear two outer side edges 141 of shanjiao rail 14 every day, 142 stress impact, by the what sinker is plates, and shanjiao rail is a blocks, and the thickness of sinker 15 increases to the limit and can't increase again, thus suffer the reciprocal impact of huge several like this following every day in this condition, in the time of one section in the future, just on the both sides body of the sinker groove 150 shown in Fig. 3 D 153, slight crack takes place and is torn into wearing and tearing and causes circular cyiinder knitting machine after running speed improves in 154 places, just take place to stop again and again and change the disappearance of sinker, the dealer who makes dare not step on the gas, and suffers untold misery in fact.

Around here, the dealer once gives induction hardening at two inboard 151 and 152 places of the groove 150 of above-mentioned sinker and handles, to remedy the fragility structure on the congenital material of sinker, the life cycle of sinker slightly can be improved in the processing back even so, but the benefit that can promote is still quite limited, really make the dealer feel as perplexed as ever even though one has racked one's brains, suffer from not having good plan.
