Abstract
The invention discloses a bottom thread supply device of a sewing machine. The bottom thread supply device comprises a rotating shuttle body and a rotating shuttle shell, wherein a round hole is formed in the center of the rotating shuttle body; a connecting rod penetrates the round hole of the rotating shuttle body; the upper end of the connecting rod is flush with the plane of the upper surface of the rotating shuttle body; the connecting rod is a hollow cylinder body; a hollow steel pipe is built in the connecting rod; the lower end of the hollow steel pipe is flush with or projects from that of the connecting rod; the upper end of the hollow steel pipe projects from the connecting rod and penetrates through the round hole in the center of the rotating shuttle body to be flush with that of a thread outlet in the rotating shuttle shell; the round thread outlet is formed in the center of the rotating shuttle shell; the rotating shuttle shell is buckled at the upper end of the rotating shuttle body; the round hole in the rotating shuttle body corresponds to the thread outlet in the rotating shuttle shell. By using the bottom thread supply device, the purpose of avoiding the replacement of a lower bottom thread in a sewing process of sewing equipment is achieved, the occurrence probability of problem about time delay due to the replacement of the lower bottom thread is reduced, the production efficiency is improved, the product defect caused by a bottom thread end due to the replacement of the lower bottom thread is also reduced, and the finished product quality is improved.
Description
Technical field
The present invention relates to a kind of rotating shuttle, relate in particular to a kind of bobbin thread for sewing machine thread supplying device, belong to the sewing-machine equipment technical field.
Background technology
Rotating shuttle is arranged in the Sewing machines and is used for the supply bottom line, often refoot after the products such as sewing textiles, leather product, plastic products disconnected lower bottom line often can occur or be finished as the traditional bottom line phenomenon of line of the rotating shuttle that uses at present; Need to shut down replacing when changing lower bottom line, waste time, affect operating efficiency, use not more conveniently, changing down, bottom line often makes product flaw occur.
Summary of the invention
In order to solve the existing weak point of above-mentioned technology, the invention provides a kind of bobbin thread for sewing machine thread supplying device.
In order to solve above technical problem, the technical solution used in the present invention is: a kind of bobbin thread for sewing machine thread supplying device, comprise rotating shuttle body, rotating shuttle shell, and the center of rotating shuttle body 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 upper end of the wire hole on 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 and the circular hole that passes rotating shuttle body center and rotating shuttle shell is concordant; The center of rotating shuttle shell is provided with the wire hole of a circle; The rotating shuttle shell is buckled in the upper end of rotating shuttle body; Circular hole on the rotating shuttle body is corresponding with the wire hole on the rotating shuttle shell.
Use of the present invention has realized that sewing device exempts to change the purpose of bottom line when sewing; Reduce the problem that the workman wastes time because changing bottom line, done production efficiency high, also reduced the Chan Pin Xia Ci that causes because of bottom line the end of a thread of changing the bottom line appearance, improved end product quality.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is overall structure schematic diagram of the present invention.
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 invention.
The specific embodiment
As shown in Figure 1, the present invention 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.Connecting rod 3 is the cylinder of hollow.The inside of connecting rod 3 is built-in with a hollow steel pipe.The upper end of the wire hole 4 on the lower end of the lower end of hollow steel pipe and the concordant or outstanding connecting rod 3 in the lower end of connecting rod 3, the outstanding connecting rod 3 in the upper end of hollow steel pipe and the circular hole 5 that passes rotating shuttle body center and rotating shuttle shell is concordant.The center of rotating shuttle shell 2 is provided with the wire hole 4 of a circle.Rotating shuttle shell 2 is buckled in the upper end of rotating shuttle body 1.Circular hole 5 on the rotating shuttle body 1 is corresponding with the wire hole 4 on the rotating shuttle shell 2.
Operation principle of the present invention:
At first empty boring in the 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, passes the rotating shuttle body, until the wire hole at rotating shuttle shell center, the mode of colluding lower bottom line is identical with the existing rotating shuttle that uses; When whole rotating shuttle and rotating shuttle bar high speed rotating, do not affect so rearmounted lower bottom line yet and enter into rotating shuttle body front straight to rotating shuttle shell line outlet place by the hollow steel pipe in the connecting rod normally.Equally, transfer the degree of tightness of bottom line at present bobbin case place, the place arranges a rocker that puts down bottom line on the backstage, bottom line just can carry out uninterrupted continuous supplying line by desk-top inlet wire behind the hollow steel pipe in the connecting rod, just can realize that lower bottom line increases many times with shuttle spindle type advance the to go to the bottom lower bottom line line length of collimation method before comparable, so just realize that sewing device exempts to change the purpose of bottom line when sewing.Hollow steel pipe and connecting rod 3 fix by fixing point 7, just can not affect the continual continuous line sending of lower bottom line when fixing rear rotating shuttle and shuttle bar high speed rotating.
Above-mentioned embodiment is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art make in technical scheme scope of the present invention also all belong to protection scope of the present invention.
