Abstract
The utility model discloses a bobbin thread feeder for sewing machines, which comprises a rotating shuttle body and a rotating shuttle shell; the center of the rotating shuttle body is provided with a round hole; a connecting rod passes through the round hole of the rotating shuttle body; the upper end of the connecting rod is flush with the plane of the top surface of the rotating shuttle body; the connecting rod is a hollow cylinder; a hollow steel tube is arranged in the connecting rod; the lower end of the hollow steel tube is flush with or extended out of the lower end of the connecting rod, and the upper end of the hollow steel tube is extended out of the connecting rod and passes through the round hole of the rotating shuttle body to be flush with the upper end of a thread outlet; the center of the rotating shuttle shell is provided with the round thread outlet; the rotating shuttle shell is fastened with the upper end of the rotating shuttle body; the round hole of the rotating shuttle body corresponds to the thread outlet of the rotating shuttle shell. The use of the bobbin thread feeder for sewing machines achieves the purpose that bobbin threads do not need to be replaced during the sewing of sewing equipment; consequently, the problem of delay as the result of bobbin thread replacement by workers is reduced, so that the efficiency of production is increased, and the defects of products caused by thread ends produced by bobbin thread replacement are reduced as well, so that the quality of finished products is increased.
Description
Technical field
The utility model relates to a kind of rotating shuttle, relates in particular to a kind of bobbin thread for sewing machine thread supplying device, belongs to sewing-machine equipment technical field.
Background technology
Rotating shuttle is arranged in Sewing machines for supplying bottom line, often refoot after the products such as sewing textiles, leather product, plastic products often there will be disconnected lower bottom line or are finished as the traditional bottom line phenomenon of line of the rotating shuttle using at present; While changing lower bottom line, need to shut down replacing, waste time, affect operating efficiency, use not more conveniently, change bottom line down and often make product occur flaw.
Utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model provides a kind of bobbin thread for sewing machine thread supplying device.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of bobbin thread for sewing machine thread supplying device, comprise rotating shuttle body, rotating shuttle shell, and rotating shuttle Ti center is provided with a circular hole; Rotating shuttle body circular hole place is penetrated with a connecting rod;
The upper end of connecting rod is concordant with the plane of the upper surface of rotating shuttle body; Connecting rod is the cylinder of hollow; The inside of connecting rod is built-in with a hollow steel pipe;
The lower end of the lower end of hollow steel pipe or outstanding connecting rod concordant with the lower end of connecting rod, the outstanding connecting rod in upper end is also concordant through the upper end of the circular hole at rotating shuttle body center and wire hole on rotating shuttle shell; Rotating shuttle Ke center is provided with a circular wire hole; Rotating shuttle shell is buckled in rotating shuttle Ti upper end; Circular hole on rotating shuttle body is corresponding with the wire hole on rotating shuttle shell.
Use of the present utility model, has realized sewing device and when sewing, has exempted to change the object of bottom line; Reduce the problem that workman wastes time because changing bottom line, done production efficiency high, also reduced the Chan Pin Xia Pin causing because changing bottom line the end of a thread of bottom line appearance, improved end product quality.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the top view of rotating shuttle body.
Fig. 3 is the bottom surface structure schematic diagram of rotating shuttle shell of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model mainly comprises rotating shuttle body 1, rotating shuttle shell 2, connecting rod 3, wire hole 4, circular hole 5, hollow steel pipe entrance hole 6 and fixing point 7.The center of rotating shuttle body 1 is provided with a circular hole.Rotating shuttle body 1 center hole place is penetrated with a connecting rod 3, and the upper end of connecting rod 3 is concordant with the plane of the upper surface of rotating shuttle body.The cylinder that connecting rod 3 is hollow.The inside of connecting rod 3 is built-in with a hollow steel pipe.The lower end of the concordant or outstanding connecting rod 3 in lower end of the lower end of hollow steel pipe and connecting rod 3, the outstanding connecting rod 3 in the upper end of hollow steel pipe is also concordant through the upper end of the circular hole 5 at rotating shuttle body center and wire hole 4 on rotating shuttle shell.The center of rotating shuttle shell 2 is provided with a circular wire hole 4.Rotating shuttle shell 2 is buckled in the upper end of rotating shuttle body 1.Circular hole 5 and the wire hole 4 on rotating shuttle shell 2 on rotating shuttle body 1 are corresponding.
Operation principle of the present utility model:
First empty boring in connecting rod, a built-in hollow steel pipe, two ends are fixed, and lower bottom line enters from the hollow steel pipe entrance hole 6 of hollow steel pipe lower end, and through rotating shuttle body, until the wire hole at rotating shuttle shell center, the rotating shuttle that under hooking, the mode co-occurrence of bottom line is used is identical; When whole rotating shuttle and rotating shuttle bar high speed rotating, do not affect so rearmounted lower bottom line yet and by the hollow steel pipe in connecting rod, enter into rotating shuttle body front straight to rotating shuttle shell line outlet place normally.Equally, at present bobbin case place, adjust the degree of tightness of bottom line, on backstage, place arranges a rocker that puts down bottom line, bottom line just can be undertaken by desk-top inlet wire after the hollow steel pipe in connecting rod uninterrupted continuously for line, just can realize lower bottom line increases many times with shuttle spindle type enter the to go to the bottom lower bottom line line length of collimation method before comparable, has so just realized sewing device and when sewing, has exempted to change the object of bottom line.Hollow steel pipe and connecting rod 3 fix by fixing point 7, when fixing rear rotating shuttle and shuttle bar high speed rotating, just can not affect the continual continuous line sending of lower bottom line.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
