Description

Multi-functional yarn-feeding device

The utility model relates to a kind of multi-functional yarn-feeding device, particularly about a kind of with the adjustable varying irregular yarn-feeding or quantitatively send yarn any send the tubular knitting machine yarn-feeding device of yarn mode.

Because the fabric of neoid tubular knitting machine is ever-changing, in active yarn transmission, often need infiltrate some again and quantitatively send yarn, so that some mouthfuls of yarn feeding wheels be form the differential tension situation under the unit send the yarn aspect, can only weave the knitwear of specific decorative pattern or color tissue, therefore this is with the dual-purpose yarn-feeding device that quantitatively send yarn and variable irregular yarn-feeding, one of technology that just becomes in the market to be pursued.It is the application case that arises at the historic moment that No. 149170 (application case number No. 77203737) " round needle loom active type Yarn Feeder Device " announced in Taiwan, this case mainly comprises: one gives yarn mechanism by this drive mechanism, should have first yarn guiding surface and second yarn guiding surface to yarn mechanism, the yarn side of going into of first yarn guiding surface is provided with the first yarn guide, the yarn side of going into of second yarn guiding surface is provided with the second yarn guide, its most important characteristic is that the frictional force of first yarn guiding surface is bigger, the frictional force of second yarn guiding surface is less, the decorative pattern that can change thread-feeding amount weaves, give yarn with first yarn guiding surface, the quantitative no decorative pattern that can not change for thread-feeding amount weaves, then give yarn, thereby have two kinds of differences concurrently and give the yarn mode in one with second yarn guiding surface.Though this case can meet the decorative pattern braiding and the no decorative pattern weaving operation of quantitatively giving yarn of above-mentioned irregular yarn quantitative changeization, this case still has following shortcoming in the use:

Because first yarn guiding surface of this irregular yarn-feeding, mainly be to utilize the tension force size of the friction force of anti-skid frottage face on rubber-covered surface and yarn demand and whether decision send the yarn or the yarn of not bothering to see me out; Therefore,, should make the contact area that has a maximum between yarn and rubber-covered surface, rely on frictional resistance between the two to reach the purpose of sending yarn when yarn during by demand; When yarn during not by demand, then should make the contact area that does not contact or have a minimum between yarn and rubber-covered surface, send yarn to avoid still going passiveness during not by demand at yarn.But this case is only by the position that is rotated of the first yarn guide, to adjust contact angle and the area between yarn and rubber-covered surface, though this case can change the position of the first yarn guide with manual manipulation mode, and then the contact angle between adjustment yarn and rubber-covered surface; In fact in operation process, operating personnel can not be according to the yarn actual demand situation of instant variation, and adjust the position of the first yarn guide at any time exactly, therefore, this first yarn guide is adjusted on the compromise position before sending the yarn operation in advance, be in one between sending really on yarn (maximum contact angle) and the compromise contact angle of avoiding sending between yarn (not contacting or the minimal contact angle degree) even also between yarn and rubber-covered surface be, this very easily in the position adjustment of the first yarn guide slightly accidentally or yarn qualities when uneven, cause high misoperation rate, that is it may be at yarn during by demand, and frictional resistance is too small and not enough and reach and send the yarn purpose; Perhaps at yarn during not by demand, frictional resistance is excessive and still continue to send the phenomenon of yarn to take place, and at least also can cause passiveness to send the yarn phenomenon, will generate for the weaving pattern of cloth so that the bar distance differs or the defective products situation of deflection.

In addition, commonly use the preferred means that variable send yarn, for example United States Patent (USP) the 3rd, 606, No. 975 variable yarn feeders, as the product type SFT of good name lattice company, this yarn feeder is to design in response to variable send the demand of yarn, this yarn feeder mainly is the size that is changed the variable thread-feeding amount by the control perception of the electronic circuit mat tension ring of inside, generally speaking, variable with microcomputer circuit control send the accuracy of yarn not comment on, but the rotating speed of Yin Mada is suddenly neglected slow variable soon and is sent in the yarn, often being limited by effect of inertia makes so, cause in the environment that being controlled at of motor be subject to disturb, the drawback that often has control to forget oneself, in addition, make the maximum puzzlement of dealer part be that the friction of tension ring and yarn is the most frequent, fault rate is also the highest, and the feed in same unit is when adopting differential tension or changing yarn tension, and this feed must be changed tension ring again and again, when so different yarns tissue or differing needles are weaved cotton cloth specification and quality after every batch of cloth production, must readjust the specification and the aspect of tension ring, make the computer irregular yarn-feeding when changing the car operation, it is rather time-consuming bothersome to change tension ring, and wearing and tearing easily again, the real microcomputer variable that become send one on the yarn big defective.

The purpose of this utility model promptly is to provide a kind of multi-functional yarn-feeding device, its can select quantitatively to send yarn and adjustable varying-quantity yarn feeding any send the yarn mode, with can corresponding no decorative pattern any of knitting and jacquard knitting send the yarn function, especially can send yarn to make the size that can adjust thread-feeding amount in response to the execute-in-place actual demand immediately to variable.

Of the present utility model time a purpose is to provide a kind of multi-functional yarn-feeding device, it is to use the V-type of great friction coefficient or channel section yarn feeding surface elastomer yarn feeding wheel as varying-quantity yarn feeding wheel, not only can solve fully and commonly use the shortcoming that rubber-covered surface is easy to slippage, and the phenomenon of yarn escape in can avoiding weaving at a high speed, and can effectively improve knitting quality.

Another purpose of the present utility model is to provide a kind of multi-functional yarn-feeding device, and its yarn path is provided with an arc movable yarn guiding mechanism, this movable yarn guiding mechanism can in response to yarn have, tension variation situation during no demand, and adjust its anglec of rotation automatically; By the guiding of arc activity guide arm, when making yarn not by demand, yarn does not come in contact with the outer surface of varying-quantity yarn feeding wheel; When yarn during by demand, yarn promptly generates the contact angle of a maximum with the outer surface of varying-quantity yarn feeding wheel, send the yarn and the two kinds of dividing lines of yarn of not bothering to see me out clearly to send the yarn state really to reach, thereby can improve the quality of the cloth of weaving.

Another purpose of the present utility model is to provide a kind of multi-functional yarn-feeding device, it is provided with one on the yarn path can adjust the presser device of yarn tension force size, so that the loaded down with trivial details technology puzzlement problem of microcomputer yarn feeder replacing tension ring is readily solved in the utility model.
