Non regulation active yarn feeder of selective multi-section speed changing or colour changing

The utility model relates to a kind of irregular active yarn transmission device, refers in particular to a kind of irregular active yarn transmission device that alternative is done multistage speed change or variable color that has.

Because human lives's quality constantly promotes, the sample attitude of dress ornament is also made every effort to variation, knitted cloth develops into the diversiform vitta cloth or the calico that directly are made into by various dyed yarns by the vegetarian noodles monochrome and releases market successively, so irregular active yarn transmission device just uses and gives birth to, knitting machine irregular yarn-feeding in early days, controlling irregular active yarn transmission with electromagnetic type is the major technology framework, for example Taiwan application for a patent for invention case number No. 7113777 " selectivity is presented the device of some yarn to horizontal yarn knitting machines really " second case is typical case's representative, but this kind device must be provided with the position induction device 7A～7D of yarn lead arm, D1/T1, D2/T2, D3/T3, D4/T4 etc., relay CR, timer TC, TD1, TD2 and very complicated compositions such as logic control circuit, because price is quite high, embarrasses market to accept.More because the elegant and attached work of knitting machine workshop cotton-wool is countless, domestic knitting environment uses this kind device often to make this logic circuit work understable, and the contact of the chief drawback is around here relay CR and timer in case last silk flosssilk wadding silk of card or flocking promptly may cause move malfunctioning, and make the paralysis of The whole control circuit, have much room for improvement in fact.

Moreover, the novel patent application case in Taiwan number No. 7223942 " the positive type yarn-feeding device of volume machine " is to provide in order to improve an aforementioned techniques difficult problem, its major technique means are when utilizing knitting machine on knitting the yarn demand to take place, this yarn tension strengthens immediately, when its tension force during greater than the default tension force of this yarn-feeding device, yarn on the yarn feeding wheel promptly spurred by activity guide arm and with having that the yarn feeding wheel of the yarn face relation of coming in contact is sent in friction the purpose of reaching irregular active yarn transmission, its simple structure and practicality.The trend in the nearly knitting market of Wei Pull is towards polychrome sampleization and two yarn

Yarn mouth development makes knitting fabric be the gentle feel of relaxing and better has the development of polychrome sample again, as desire to try to achieve double-colored or three looks alternately braiding change the cloth product time, just this yarn feeding wheel need be provided with two-layer or three layers, begin to deal with the technical need of factory on same vertical line.Because this yarn feeding wheel, as shown in Figure 9, movable yarn lead 45 and tenslator be located at yarn feeding wheel 17,18 and driving wheel 16 under, if under same yarn feeding wheel, carry simultaneously two kinds of dyed yarns or four yarns need be provided with when weaving cloth with decorative pattern two-layer or two-layer more than during this kind yarn feeding wheel, operation is highly greatly improved, cause the operator entrying and connecing difficulty on the yarn, and when control speed or speed governing, its height is on the number of people, and is quite inconvenient.Flock together because of many yarns are parallel again and cause faulty operation easily making relation between each yarn be difficult for putting in order.As for the setting of the yarn feeding wheel more than three layers or three layers, its operational puzzlement takes place with wrong, with more shape is serious, its technical difficulty is arranged quite in the enforcement.Especially bad, as can't satisfying knitting demand in the speed with its delivered yarn of yarn feeding wheel of one deck configuration, and need yarn is caused last layer or down during the yarn feeding wheel of one deck, must earlier yarn be split off, connecing yarn again and lead the yarn beginning can be for it.So, quite time-consuming taking a lot of work in changing the car operation, to the situation of the labourer of knitting boundary deficiency today, being as good as is to make the matter worse, so that this case seemingly belongs to as double-colored knitting irregular active yarn transmission in theory is feasible, truly has above-mentioned difficulties in the right practical operation.In addition, whether Decision send the yarn or the yarn of not bothering to see me out surely because the major technique means of this irregular yarn-feeding are utilized the tension force size Er of the effect of anti-skid frottage face of yarn feeding wheel periphery and yarn demand fully, but this case yarn feeding wheel is not when bothering to see me out yarn, as shown in figure 10, yarn 76 still has the above contact angle of at least nine ten degree with frictional property yarn feeding wheel periphery, when if the coefficient of friction of the friction outer peripheral face of yarn feeding wheel is big, to cause misoperation, that is under the situation that non-yarn is required, contacting of suitable angle because of taking place with the rubbing surface yarn feeding wheel in yarn 76, cause under the yarn situation of not bothering to see me out, still having and send the yarn phenomenon to take place, this phenomenon organizes coefficient of friction the greater even more serious with yam surface especially, at least also can cause passiveness to send the yarn phenomenon, so will produce that the bar distance differs or the defective products situation of deflection for the weaving pattern of cloth, though fixedly guide arm 25 can be adjusted as shown in figure 11, make the yarn 76 and the contact angle of yarn feeding wheel 17 peripheries transfer to Min., begin to reach hundred-percent active yarn transmission and when active yarn transmission, desire to ask contact angle to transfer to as far as possible greater than 180 degree.But the guide arm 25 of this yarn feeding wheel is located at yarn feeding wheel top, yarn feeding wheel nearly 120 each yarn feeding wheel all needs to adjust one by one when above, suitable difficulty in operation in fact also can not be implemented.In addition, if be used in double-colored weaving or three looks when weaving, the operation and the adjustment of the height of the second layer or the 3rd layer will be the suitable things of difficulty, thus this movably fixed arm 25 be unable to cope with the demand in current knitting market in fact.

Moreover, when if the variegated yarn of the same running speed of this yarn feeding wheel is weaved operation, though can be arranged on same horizontal level, but yarn feeding wheel is arranged on the too hour not only very inconvenience of operation of yarn of spacing on the annular lath, influence changes car time and output size, even cause the remote cause of fault easily, between general yarn, add when weaving present most popular elastic caoutchouc yarn or metallic yarn again if desire, can't reach because of its space is restricted, make the modal shift of its knitting fabric can't satisfy the market demands that current wink is ten thousand changes.If, each yarn feeding wheel of this yarn feeding wheel is carried two yarns reluctantly simultaneously, then has only single eyelet because of its guide eye, though the tension force of yarn can be exerted oneself the relation of two yarns to give and drawn back when sending yarn, but in case send yarn to stop, when yarn tension disappears, the own Twist degree of each yarn just makes it go on the yarn stroke and automatically mutual approaching two yarns or three skeins is lumped together, so when driving once again, just formed the reason of fault, so this yarn feeding wheel can only carry single yarn in fact, can't two yarns carry simultaneously also to be its constructional defective.

Therefore, main purpose of the present utility model is to provide a kind of alternative to make the irregular active yarn transmission device of multistage speed change or variable color, with plural yarn feeding wheel and two or more belt pulleys with clutch with on the coaxial bearing that is fixed in same yarn feeding wheel support of rotatable mode, and the tensioner of activity guide arm is arranged at a side of yarn feeding wheel, thereby can make the shared same driving shaft of many group yarn feeding wheels, relending two above clutches selects to use, with selected optimal running speed, not only the whole height of multilayer yarn feeding wheel is moderate, level interval between each multilayer yarn feeding wheel also increases, when same dyed yarn send yarn speed in conversion, needn't change yarn and entry again, so entrying yarn, lead yarn, operation such as speed change and variable color or processing are all very convenient.
