Description

But the sewing machine shuttle of continuously feeding ground thread

Technical field

The present invention relates to shuttle axle, Ding Suo and the bottom line looper of a kind of sewing machine shuttle, particularly a kind of sewing machine shuttle.

Background technology

Sewing machine shuttle is the parts of Sewing machines feeding ground thread.Sewing machine shuttle has annular rotating shuttle and the annular in rotating shuttle to decide shuttle; rotating shuttle is connected with the shuttle axle; on deciding at the bottom of the shuttle shuttle of deciding axle is arranged; the outer edge of deciding shuttle has positioning port; there is the bottom line line outlet on the positioning port side; bobbin thread for sewing machine is on the bottom line axle; the bottom line axle is contained in the shuttle intracutaneous, and the shuttle skin that the bottom line axle is housed is embedded in Ding Suonei, and the shuttle skin has wire hole; wire hole is by the bottom line line outlet; bottom line is drawn to pull out through the bottom line line outlet of deciding the shuttle outer edge from shuttle skin wire hole and is sewing supply bottom line, and the bottom line in the sewing machine shuttle is on the bottom line axle, and the bottom line axle is less; the bottom line that twines is less; during use, often shut down and take out the empty bottom line axle use up bottom line, on empty bottom line axle around full bottom line; loading onto, cause sewing work efficient low again around the bottom line axle of full bottom line.In order to increase work efficiency, in the prior art, a kind of bobbin thread for sewing machine device is disclosed in the Chinese patent 95227302.0, the bobbin thread for sewing machine device has rotating shuttle and wire clamp, the parallel side of being located at eedle of wire clamp, bottom line is to supply line with the tower line, and bottom line passes wire clamp and leads to sewing supply bottom line after the degree of tightness of tension disk adjusting bottom line.The bottom line of this bobbin thread for sewing machine device is to introduce outside the shuttle head for line, and during use, bottom line is subjected to oil pollution or produces bottom line to be obstructed, to twine easily, influences product quality and continuously feeding ground thread.

Summary of the invention

The objective of the invention is in order to overcome above-mentioned deficiency, but bottom line can not be subjected to the sewing machine shuttle of the continuously feeding ground thread that oil pollution, bottom line can not be obstructed or twine when proposing a kind of the use.

The present invention is achieved using the following method.

But the sewing machine shuttle of continuously feeding ground thread has annular rotating shuttle and the annular in rotating shuttle to decide shuttle, rotating shuttle is connected with the shuttle axle, the outer edge of deciding shuttle has positioning port, there is the bottom line line outlet on the positioning port side, decide shuttle and be the annular of open loop and decide shuttle, the shuttle axle is tubular hollow shuttle axle, be with the bottom line pipe of axis on same straight line of axis and shuttle axle in the hollow shuttle axle, stretch out outside the shuttle axle outer end of bottom line pipe, bottom line pipe a section outside the shuttle axle is a bend loss, and the inner of bottom line pipe puts in decides in the shuttle ring, and the inner of bottom line pipe is connected with the bottom line looper, on the bottom line looper through wires hole is arranged, the through wires hole at bottom line looper needle point place is being decided by the bottom line line outlet of shuttle outer edge.

During use, the bend loss of bottom line pipe is fixed, bend loss one end from the bottom line pipe behind the tension disk of one end of tower line through regulating the bottom line degree of tightness is penetrated, pull out from an end of deciding in the shuttle ring, the through wires hole on the bottom line looper passes again, allows the line that passes from the through wires hole of bottom line looper needle point pull out from line outlet, driving the shuttle axle with power rotates, because of bend loss is fixed, the shuttle axle rotates can not drive the rotation of bottom line pipe, and the line of pulling out from line outlet can be sewing supply bottom line.

Bottom line of the present invention is to introduce in the shuttle head for line, during use, can not be subjected to oil pollution, can not produce bottom line and be obstructed or twine, reliably continuously feeding ground thread.

Below in conjunction with accompanying drawing, the present invention is further described.

Description of drawings

But Fig. 1 is the main cross-sectional schematic according to the sewing machine shuttle of a kind of continuously feeding ground thread of invention scheme proposition of the present invention;

Fig. 2 is that the solid of Fig. 1 splits schematic diagram;

But Fig. 3 is the shuttle axle is the main cross-sectional schematic of sewing machine shuttle of the continuously feeding ground thread of off-axis.

The specific embodiment

Fig. 1, among Fig. 2, but the sewing machine shuttle of continuously feeding ground thread has annular rotating shuttle 1 and the annular in rotating shuttle to decide shuttle 2, rotating shuttle is connected with shuttle axle 3, the outer edge of deciding shuttle has positioning port 4, there is bottom line line outlet 5 on the positioning port side, decide shuttle and be the annular of open loop and decide shuttle, the shuttle axle is tubular hollow shuttle axle, be with the bottom line pipe 6 of axis on same straight line of axis and shuttle axle in the hollow shuttle axle, stretch out outside the shuttle axle outer end of bottom line pipe, bottom line pipe a section outside the shuttle axle is a bend loss 7, the inner of bottom line pipe puts in decides in the shuttle ring, and the inner of bottom line pipe is connected with bottom line looper 8, and the bottom line looper has looper body 16, one end of looper body is connected with annulus 9, the interior circle hole sleeve of annulus is evenly equipped with holding screw nail 10 in bottom line pipe the inner on the circumference of annulus, the other end of looper body is a needle point, through wires hole 11 is arranged on the looper body, and the through wires hole 12 at bottom line looper needle point place is being decided by the bottom line line outlet of shuttle outer edge.

But the shuttle axle of the sewing machine shuttle of above-mentioned continuously feeding ground thread can be elongated shuttle axle, also can be the middle off-axis that disconnects section that has, and the bend loss of bottom line pipe stretches out in the disconnection section of shuttle axle.

Among Fig. 3, but the shuttle axle is in the middle of the shuttle axle of sewing machine shuttle of continuously feeding ground thread of off-axis the section of disconnection 13 to be arranged, and disconnects the side shaft 15 that useful gear 14 links to each other between the section, and the bend loss 17 of bottom line pipe stretches out in the disconnection section of shuttle axle.Outer section axle 18 of side shaft and shuttle axle can be solid shafting.
