Description

Shengke slice and its shanjiao rail improved structure of drum knitting loom

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 arris rail thereof that makes, with effective enhancing sinker meeting with stresses in its reciprocating stroke action, to solve the settlement triangle rail sinker applied stress is too concentrated the drawback on single composition surface, thereby significantly improve sinker and arris rail thereof.

As is generally known, sinker is to cooperatively interact with knitting needle in knitting process, 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, the sedimentation single-side machine is when braiding, and it goes out pin, narrows in time apart from the weave effect that all promotes knitting needle and reach yarn by settlement triangle rail promotion sinker (sinker) by triangle (cam).With regard to its operating principle, all adopt orthogonal motion mode between the sedimentation ring of sedimentation single-side machine and syringe, because of sinker system with level to running, just in time be vertical interaction with the vertical of knitting needle mutually to action.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 the settlement triangle rail with sizable stress in running up around here, make the acting surface damaged phenomenon of the groove that the settlement triangle rail acted on quite frequent, the knitting machine sinker and the action relationships between arris rail thereof that cooperate Fig. 1 to 3 to commonly use now again describe in detail as follows:

Known circular cyiinder knitting machine structure, as shown in Figure 1, comprise triangle seat ring 10, establish Triangulum 11 on it, the Triangulum top is established sinker cam seat 12 again, settlement barrel 13 and settlement triangle rail 14 are established in the below of sinker cam seat 12, establish sinker 15 in

settlement barrel

13 and 14 folders of settlement triangle rail, the circumferential outer edge relative with the Triangulum 11 of knitting needle established syringe 16, running in order to control knitting needle 17, the top of knitting needle 17 is provided with yarn feeding and chews 18, as seen from the figure, sinker 15 be arranged in settlement triangle rail 14 and with knitting needle 17 reciprocations to go the weaving operation of yarn.

The knitting needle and the sinker action relationships between the two of consulting now 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 the position, we 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 by settlement triangle 150, shown in the 1st of Fig. 2 B; When sinker is subjected to the effect of triangle 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 of triangle 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 earlier be pushed into the position, forefront 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 running so again and again is known knitting whole process.

As shown in the above description, two inner side edges 151 and 152 of the arris rail effect groove 150 of sinker 15 are to be subjected to the dual-side 141 of arris rail 14 and 142 reciprocating motion fully respectively and to advance in Triangulum 12 and Hou is moved back shown in Fig. 3 A to 3D, this reciprocating number of times that moves back with Hou that advances still improves with the quickening of the knitting board running speed of work, because the hosiery trade competition is day by day according to strong, 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, therefore the dealer just manages to increase the feed number and improves running speed on knitting machine, 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 Hou person then is subjected to the knitting machine abrasion of part in addition, especially sinker is subjected to the stress impact effect maximum of arris rail, for example with 30 cun knitting machines that diameter is big, total feed number is 150 mouthfuls of numbers, per minute rotating speed (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 cam rail 14, in like manner its 152 limit is acted on by 142 limits of sinker cam rail 14, that is, two inner side edges 151 of the groove 150 of sinker, 152, need bear two outer side edges 141 of arris rail 14 every day, 142 stress impact, by the what sinker is plates, and arris rail is a blocks, and the thickness of sinker 15 increases to the limit and can't increase again, so suffer the reciprocal impact of huge several like this following every day in this condition, one period Hou in time, just on the both sides body of the sinker groove 150 shown in Fig. 3 D 153, slight crack takes place and is torn or weares and teares and cause circular cyiinder knitting machine to improve Hou in running speed 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, process Hou even so and slightly can improve the life cycle of sinker, 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.

Therefore; purpose of the present invention is promptly in the improvement of the sinker that a kind of circular cyiinder knitting machine is provided and its arris rail structure; the composition surface that each sinker and its arris rail are had an effect is changed into by concentrated face and is scattered in an above composition surface; so as to disperseing from the applied stress on the arris rail; thereby the stress that each sinker is born significantly reduces and increases cycle in service life of sinker, this not only the running speed of circular cyiinder knitting machine can improve and outage rate is also obtained significantly and improved.

For realizing above-mentioned purpose of the present invention; each sinker is set up at least one protuberance in the groove that arris rail acted on; two acting surfaces of this each protuberance are corresponding mutually with two acting surface systems of sinker groove; and also corresponding setting at least one concave part on arris rail; the tortuosity of this concave part and gauge relation are all identical with former arris rail; the size system of concave part is complementary with the protuberance of sinker; thereby the settlement triangle rail is scattered on two acting surfaces of each protuberance in the sinker groove by the known both sides that concentrate on groove to the stress of sinker; the stress that sinker is born significantly reduces; to improve the service life of sinker; obtain significantly in order to do the outage rate of circular cyiinder knitting machine and to improve, the lifting of China's hosiery trade production technology is had much contribution.
