Abstract

The utility model relates to a non-rim yarn storing wheel for knitting machines, which is mainly formed by sheathing a driving wheel and a driven wheel, wherein, the center of the driven wheel is provided with a shaft hole, and the outer edge of the driven wheel is provided with a flange; more than one cutting grooves are arranged on outer side edges of the yarn storing wheel, both sides of the top end of the cutting grooves are provided with shaft bases, and the shaft bases are used for inserting convex shafts at the left and the right sides of a movable block; the gravity of the shaft bases makes the front end of the shaft bases extend from the yarn storing wheel, which makes raw yarn entwining round the yarn storing wheel blocked by the front end of the movable block when the raw yarn falls so that re-coiling is not needed; the movable block can follow to retract inward when broken threads are pulled down by hand. The utility model has the advantages of simple structure, convenient installation, convenient maintenance and strong durability.

Description

Knitting machine does not have the wheel rim yarn storage wheel

A kind of knitting machine does not have the wheel rim yarn storage wheel, it is the improvement on the basis of existing equipment, especially refer to a kind of do not have at knitting machine be provided with more than one movable block on the wheel rim yarn storage wheel, the outer rim that the front end of this movable block protrudes in yarn storage wheel can stop that yarn glides, when operating personnel are left behind remaining yarn with hand, the knitting machine that movable block contracts in can taking advantage of a situation does not have the wheel rim yarn storage wheel, belongs to field of textile machinery knitting machine class.

The yarn storage wheel of prior art (Fig. 1), be installed on the frame of Feeder of knitting machine, during use yarn is pulled out supply yarn B by yarn tube A, through a yarn guide C, one filter yarn sheet D, between a pair of pressure yarn sheet E, one stop rod F below, the first porcelain eye G, on yarn storage wheel H, twine a few, again through the top of feeder seat I porcelain rod, following stop rod J below porcelain rod K, the second porcelain eye L is to the knitting needle of knitting machine, to carry out knitting operation, wherein the effect of yarn storage wheel H mainly is to allow yarn B pull out and even winding number circle on yarn storage wheel H from yarn tube A in advance, pull out again carry out knitting, yarn storage wheel H provides the yarn of high stable tension force, improve the quality of products and stability, and existing yarn storage wheel H is socketed to form mutually by driving wheel M and driven pulley N, when using nylon wire, because nylon wire is made up of tens of thighs or more filament, several bursts of fractures are arranged during operation unavoidably, these filaments are adsorbed on yarn storage wheel H and the extension rod P because of the static relation, long-pending to a certain degree influencing yarn storage wheel H normal operation, for remaining yarn bits are got rid of the normal supply that does not influence yarn B automatically, therefore the outer rim of the extension rod P of present many yarn storage wheel H is greater than driving wheel M bottom outer rim (promptly not having the wheel rim yarn storage wheel), the residual line that is around on the yarn storage wheel H can be fallen automatically by extension rod P bottom, though aforementioned structure can be discharged the yarn bits smoothly, solved the shortcoming that yarn storage wheel runs well, but when using the relatively poor yarn of adhesive force when (precursor or Fil-Lumiere), because of diminishing, the tension force of yarn B stop rod J is fallen cause autostop, it is lax that yarn B is produced, because of yarn B poor adhesive force, easily make the quick landing of yarn B that is around on the yarn storage wheel H, must be again again around getting on, make operation inconvenience, cost increases; Someone has applied for preventing the yarn storage wheel of yarn downslide, as " the yarn storage wheel structural improvement of storage yarn yarn feeding wheel " Taiwan patent announcement 330597 (Fig. 2) a centrifugal resetting means Q is established in the inside of yarn storage wheel P, the bottom surface of this centrifugal resetting means Q is arcuation face seat R, be distributed with around the outer shroud of dish seat R and be lower than outer top surface of ring becomes a straight breach with the outer ring a plurality of slide S slightly, form the chute T that increases progressively with certain altitude in slide S with respect to an end that coils seat R center, other has several fins U of certain thickness T shape to stride across a dish seat R center of circle respectively to overlap in regular turn and be disposed at respectively on the slide S, fin U is positioned at the last end in addition of slide S and is platy structure baffle plate V, end with respect to baffle plate V is installed with the weight W big than baffle plate V, the tail end face of weight W is provided with a hole seat X, one spring Y inserts on the seat X of hole, when aforementioned structure is rotated as yarn storage wheel P, weight W on the fin U outwards moves because of centrifugal force pressuring spring Y, make the catch V withdrawal of the fin U other end, fin U makes fin U be subjected to the power of spring Y to make catch V extrapolated because of centrifugal force disappears when yarn storage wheel P stops the rotation, can reach the purpose that stops that yarn B glides, but still have part many, the shortcoming that cost is high and assembling is difficult, if can't when yarn storage wheel rotates, directly residual yarn be taken off (because of hand is easily got to by extension rod) when being used in yarn storage wheel with hand with extension rod, if just residual yarn is taken off when static Deng yarn storage wheel, must press simultaneously with pointing three catch V that will protrude in yarn storage wheel, make catch all in the retraction yarn storage wheel, it could be taken off, not only loaded down with trivial details and can cause operator greatly inconvenience and puzzlement, be the problem that the utmost point waits to study improvement.

The purpose of this utility model is: provide a kind of knitting machine not have the wheel rim yarn storage wheel, can not blocked by the movable block front end when precursor that is around on the yarn storage wheel is fallen and can take off yarn storage wheel easily; This movable block can be when with hand residual line being left behind contracts in automatically, does not influence work, extension rod can be fixed when borrowing the setting of flange and groove that loam cake is combined with base.

The purpose of this utility model can realize according to following technical scheme: driving wheel is made up of base, loam cake and extension rod, there is a crooked flanging extension rod lower end, the angle of flanging and extension rod is greater than or less than 90 degree, cooperate the bottom of loam cake to be provided with flange, be provided with for the fixing groove of extension rod at base top surface; Driven pulley central authorities are provided with an axis hole, and driven pulley outer rim top is provided with a flange, the flange below in mode uniformly-spaced around being provided with a plurality of shrinkage pools; This yarn storage wheel side outer rim is provided with more than one grooving, and top two sides of grooving are provided with axle bed, and the protruding axle of two sides is inserted axle bed about a movable block; The utility model can realize that also the inner face of this groove can cooperate with the crooked cambered surface of extension rod root edge according to following measures, and the outside of groove is higher than inboard; The bottom surface of this loam cake is provided with projection, and the end face relative position that is engaged in base is provided with shrinkage pool; The bottom surface of this driven pulley is provided with projection, is engaged in driving wheel end face relative position and is provided with shrinkage pool; This grooving is located on the driving wheel in the yarn storage wheel.

The utility model has the advantages that: have easy structure, be easy to make assembling, increase substantially the durability of product, the advantage of the continuous landing of the prevention relatively poor yarn of adhesive force is arranged.
