Description
Technical field
The utility model relates to a kind of accessaries of sewing machine, and in particular, it relates to a kind of tortuous seam rotating shuttle.
Background technology
Rotating shuttle is the important composition part of Sewing machines, on the lock-type chain stitch suture type Sewing machines the most generally using, mostly adopt rotating shuttle in the industries such as clothing shoemaking, when work, catch on wire loop with the spur of rotating shuttle, expand wire loop simultaneously, and guide wire loop to form lock-type chain stitch around crossing shuttle.In rotating shuttle high speed operation process, between the upper thread wire loop that the bottom line storing in rotating shuttle and eedle are sent here, constantly shuttle back and forth, interweave, tighten up, friction between bottom line and upper thread wire loop can produce a large amount of fiber hair, and the shuttle race of rotating shuttle, between shuttle frame, also can produce dust because of attrition, fiber hair, dust can be polymerized to incrustation in rotating shuttle inner product, can affect shuttle race in rotating shuttle as cleared up not in time, cooperation flexibility ratio between shuttle frame, generation outlet has some setbacks, wire jumper, the faults such as broken string, for overcoming these problems, conventional way is to pull down rotating shuttle to clear up, waste time and energy, affect production efficiency.It is a kind of for the rotating shuttle on Sewing machines that publication number is that the utility model of CN2538825Y disclosed on March 5th, 2003, contains rotating shuttle shell and track, establishes rail groove in track, on rotating shuttle shell and rail groove, through hole is set respectively, and the through hole on the two connects.In the time of rotating shuttle High Rotation Speed, under the effect of centrifugal force, the dust accumulating in groove in-orbit can be blown out to rotating shuttle by through hole.This rotating shuttle, in the time running up, energy dust out automatically, does not need frequent dismounting, can extend the service life of rotating shuttle, greatly increases work efficiency.But utility model only relies on centrifugal force that dust is discharged, and cleaning effect is comparatively limited.
Utility model content
Rotating shuttle can generate mechanism in operation process, is unfavorable for the normal work of rotating shuttle, and for addressing this problem, the utility model provides one can remove in time fiber hair, dust, prevents from forming the complications seam rotating shuttle of incrustation.
The technical solution of the utility model is: a kind of tortuous seam rotating shuttle, be located on industrial sewing machine, this rotating shuttle comprises shuttle race, shuttle frame, protect needle plate and Yue Quan, shuttle race is provided with the cavity of open-top, shuttle frame rotates and is embedded in shuttle race cavity, protecting needle plate and a month circle is fixedly arranged on respectively in shuttle race bottom and periphery, shuttle race bottom is provided with shuttle race connecting axle, shuttle race connecting axle is hollow structure, shuttle race bottom is provided with the pore being communicated with shuttle race connecting axle internal cavity, shuttle race connecting axle is connected with the rotating shuttle driving shaft of Sewing machines, described rotating shuttle driving shaft is also hollow structure and external compressed gas source.The compressed air of the moderate pressure that compressed gas source provides blows to shuttle race inside through rotating shuttle driving shaft, shuttle race connecting axle, pore, the foreign material such as fiber hair, dust are dispelled in time, make it cannot gather formation incrustation, thereby keep the cleaning of rotating shuttle, guarantee rotating shuttle is normally worked.
As preferably, the axis of pore becomes angle structure with the axis of shuttle race connecting axle, and pore in the aperture of shuttle race inside to the distance of shuttle race connecting axle axis be greater than pore in the aperture of shuttle race outside the distance to shuttle race connecting axle axis.The axis that the pore of this structure departs from gradually shuttle race in the export-oriented shuttle race of shuttle race, tilt blow, air-flow blows to shuttle race sidewall, be subject to shuttle race sidewall stop rear formation more multithread to air-flow, make inner each corner of rotating shuttle have air-flow to pass through, fiber hair, dust cannot stop.
As preferably, the cavity bottom of shuttle race is provided with oilhole, and oilhole port is provided with oil seal cover, in oilhole, be provided with wool felt, in shuttle race sidewall, be provided with and be communicated with oilhole and pass to shuttle frame and the oil guide groove of shuttle race sidewall auxiliary section, oil guide groove connects shuttle race sidewall, and oil guide groove external port is provided with sealing stopper.Between shuttle race and shuttle frame, contact all the time attrition, if things go on like this can cause fit clearance to increase, a small amount of lubricating oil of annotating between shuttle race and shuttle frame of being everlasting while therefore needs, alleviates wearing and tearing, increases the service life.Oilhole, oil guide groove are set, can form oil supply gallery, be convenient to carry out daily oiling maintenance, oil seal cover and sealing stopper can refuel other oil circuit outlet of rear enclosed, make oil only flow to and need lubricant housings, wool felt can conserve fluid, avoids too much mobile fluid to exosmose.
The beneficial effects of the utility model are:
Keep the cleaning of rotating shuttle.The utility model, in the time of work, can constantly be blown to shuttle race inside, and the foreign material such as fiber hair, dust dispel in time, make it cannot gather formation incrustation, thereby keeps the cleaning of rotating shuttle, and guarantee rotating shuttle is normally worked.
