Abstract

The utility model relates to a novel rotating shuttle holder comprising a cylindrical sidewall, a bottom and an upper end face. One end of the cylindrical sidewall is connected with the bottom. A shuttle mandrel is disposed at the center of the bottom. The other end of the cylindrical sidewall is connected with the upper end face. A C-shaped guide is arranged on the periphery of the cylindrical sidewall and is provided with a plurality of waste grooves. The front end of the C-shaped guide and the rear end of the C-shaped guide are spaced. The front end of the C-shaped guide is provided with a divider hook. The axis of the C-shaped guide and that of the shuttle mandrel are not overlapped; the C-shaped guide and the shuttle mandrel form an eccentric mechanism; the eccentric mechanism is 0.483 in eccentricity. The novel rotating shuttle holder has the advantages that rotational centrifugal force of the novel rotating shuttle holder is increased, and accordingly, smooth line shedding is guaranteed when thick lines or multiple lines are used on a rotating shuttle.

Description

A kind of Novel rotary sacsaoul frame

Technical field

The utility model relates to rotating shuttle rack, relates in particular to a kind of Novel rotary sacsaoul frame.

Background technology

Traditional shuttle frame is mainly by cylindrical side wall, go to the bottom, upper end, guide rail, separating hook, shuttle axle forms, and sidewall is cylindrical, goes to the bottom and is connected to one end of sidewall, upper end is linked at the other end of sidewall, periphery at sidewall is also provided with C shape, and the spaced guide rail of front and back tool, and separating hook is connected to the front end of guide rail, on guide rail, operated by rotary motion is by one to eight refuse chute, and Xia Di center connects shuttle axle.There is not eccentric design in traditional sewing-machine rotating shuttle shuttle frame.Because its rotating shuttle that is specifically arranged so that every kind of model can only be used single suture, as 7.94A model rotating shuttle can only be used thick line, and can not use fine rule, metallized thread and and modern quilt exigence, a kind of rotating shuttle of model can be used multiple suture, so not only enterprise's production cost can be reduced, and enterprises production efficiency can be improved greatly.How, on existing rotating shuttle basis, realize a kind of rotating shuttle and can use multiple suture just to become very necessary.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of Novel rotary sacsaoul frame, solves the deficiencies in the prior art.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of Novel rotary sacsaoul frame, and it comprises cylindrical side wall, goes to the bottom, upper end; Go to the bottom described in connecting in one end of described cylindrical side wall, described in the center of going to the bottom be provided with shuttle axle; The other end of described cylindrical side wall connects described upper end; The periphery of described cylindrical side wall is provided with C shape guide rail, and described guide rail is provided with a plurality of refuse chutes; Between the front end of described guide rail and the rear end of described guide rail, interval is set; The front end of described guide rail is provided with separating hook; The central shaft of described guide rail does not overlap with the central shaft of described shuttle axle, and described guide rail and an eccentric stiffener of described shuttle axle composition, and the degree of eccentricity of described eccentric stiffener is 0.483.

The beneficial effects of the utility model are: the centrifugal force while having increased rotating shuttle rack running, thus guarantee that rotating shuttle off-line when using thick line, multi cord is smooth and easy.

Further: the cylindrical of the central shaft of described shuttle axle and the below of described guide rail forms an eccentric structure, and the offset of cylindrical is 0.426.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is right view of the present utility model;

Fig. 3 is rearview of the present utility model;

Fig. 4 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 1, a kind of Novel rotary sacsaoul frame, it comprises cylindrical side wall 1, go to the bottom 2, upper end 3; One end of described cylindrical side wall 1 goes to the bottom 2 described in connecting, described in 2 the center of going to the bottom be provided with shuttle axle 6; The other end of described cylindrical side wall 1 connects described upper end 3; The periphery of described cylindrical side wall 1 is provided with C shape guide rail 4, and described guide rail is provided with a plurality of refuse chutes 7; Between the front end 4-1 of described guide rail 4 and the rear end 4-2 of described guide rail 4, interval is set; The front end 4-1 of described guide rail 4 is provided with separating hook 5; The central shaft of described guide rail 4 does not overlap with the central shaft of described shuttle axle 6, and described guide rail 4 forms an eccentric stiffener with described shuttle axle 6, the degree of eccentricity of described eccentric stiffener is 0.483, make the front end 4-1 of described guide rail 4 and the wire containing of rear end 4-2 increase 0.50 millimeter, increased the centrifugal force of total, thereby guaranteed that the utility model off-line when using thick line, multi cord is smooth and easy.

As shown in Figure 1, the rear end 4-2 of described guide rail 4 is off-line end, starting point 4-2.1, end point 4-2.2 that off-line end 4-2 is provided with; Line between end point 4-2.2 and starting point 4-2.1, and starting point 4-2.1 and 2 the central point of going to the bottom between the angle of line be &, &=71.5 °, thereby guarantee that the utility model is when suture take-up, can there be enough autonomous transformation spaces, prevent from producing the phenomenons such as clamp, broken string when using not collinear running.

As shown in Figure 2, the cylindrical 8-1 of the below of the central shaft of described shuttle axle 6 and described guide rail 4 (the cylindrical 8-2 of the top of guide rail 4) forms an eccentric structure, the offset of cylindrical 8-1 is 0.426, bias by this designs, more perfect the utility model when multiple line conversions such as using thick line, fine rule, multi cord is used, the smoothness of the off-line of rotating shuttle own and take-up.

As shown in Figure 3, the eccentric design of 2 profile 9 of going to the bottom, the offset of profile 9 is 0.39, by this eccentric design, guarantees that the utility model turns over line amount and can change voluntarily with line style, can smooth and easy operation when using not synteny thereby guarantee.

As shown in Figure 4, on the circumference of cylindrical side wall 1, the below between front end 4-1 and rear end 4-2, is provided with pin window 10, pin window 10 the right and lefts carry out not reciprocity design, pin window 10 one end are L1 to the distance of center line, and pin window 10 other ends are L2 to the distance of center line, L1=4.5mm, L2=7.3mm, thereby realize freely adjusting of pin window wire containing, thereby guarantee that the utility model is being used differently when linear, there will not be the phenomenons such as broken string, clamp and card machine.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
