Description
Technical field
A kind of rotating shuttle structure is the utility model is related to, more particularly to small, rapid heat dissipation is worn between a kind of shuttle race and shuttle frame, and can
Rubbish is removed outside guide rail at any time, extends the lubrication pollution discharge structure of the sewing-machine rotating shuttle shuttle frame guide rail of rotating shuttle service life.
Background technology
Rotating shuttle is the important composition part of sewing machine, and the lock-type chain stitch most generally used in the industries such as clothing shoemaking sutures
On formula sewing machine, mostly using rotating shuttle, wire loop is caught on the spur of rotating shuttle during work, while expands wire loop, and guides wire loop ring
Lock-type chain stitch is formed around shuttle frame.In existing sewing-machine rotating shuttle structure, the shuttle frame guide rail on shuttle frame is corresponding with shuttle race
Track platform is sliding friction, in being in relative to shuttle frame and to be rotated at a high speed due to shuttle race during use, therefore in order to reduce between the two
Friction, ensure rotating shuttle maintain normally work, it is necessary to regularly to being lubricated fuel feeding outside shuttle frame guide rail and track platform, stop
Machine operates, and not only process is cumbersome, and volume read-out is often difficult to control, and needs frequent shutdown to refuel during volume read-out deficiency, volume read-out mistake
When big, excessive waste is not only caused, while excessive lubricating oil even can pollute sewing thread or clothing, so as to influence product matter
Amount.Simultaneously because during rotating shuttle high speed operation, constantly enter between the upper thread wire loop that the bottom line of storage and eedle are sent in rotating shuttle
Row shuttles, interweaved, tightening up, and the friction between bottom line and upper thread wire loop can produce a large amount of fiber hairs, and between the shuttle race of rotating shuttle, shuttle frame
Can produce dust because of attrition, fiber hair, dust simultaneously accumulate in rotating shuttle and are internally formed dirt, dirt directly affect shuttle race in rotating shuttle,
The failures such as the cooperation flexibility ratio between shuttle frame, easily generation outlet have some setbacks, wire jumper, broken string, in order to ensure the normal work of rotating shuttle, are also needed
Periodically to disassemble shuttle frame and bobbin case carries out garbage-cleaning, waste time and energy, influence normal production operation.
The content of the invention
The utility model wears small, rapid heat dissipation between mainly there is provided a kind of shuttle race and shuttle frame, and rubbish can be removed automatically
To outside guide rail, so as to ensure that rotating shuttle normal work, and the lubrication row of the sewing-machine rotating shuttle shuttle frame guide rail of service life is extended
Dirty structure, solves shuttle frame guide rail present in prior art and shuttle race frictional resistance is big, need to be regularly to shuttle frame guide rail and rail
Platform where rites are performed is lubricated fuel feeding and garbage-cleaning, laborious during expense, directly affects the technical problem of sewing operation efficiency etc..
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of sewing machine rotation
The lubrication pollution discharge structure of sacsaoul frame guide rail, including shuttle frame and the bobbin case that is fixed on the shuttle frame fuse of shuttle frame one end, in the another of shuttle frame
One end interworking is covered with the shuttle race that can be rotated relative to shuttle frame fuse, moon circle is provided with the outer ring surface of shuttle race, in the shuttle race
Inner ring surface is provided with track platform, and annular shuttle frame guide rail is provided with the outer ring surface of shuttle frame, and shuttle frame passes through annular shuttle frame guide supporting
Keep being slidably connected on in-orbit platform where rites are performed and with the inner ring surface of shuttle race, if being provided with track platform surface corresponding with annular shuttle frame guide rail
Dry Sediment trap.By the multiple Sediment traps of surface setting of in-orbit platform where rites are performed, caused dirt can pass through during sewing operation

To export groove.By setting the oblique export groove of rubbish on the outer ring surface of annular shuttle frame guide rail, it can at any time remove and lead at work
In rail platform while rubbish, the contact area of annular shuttle frame guide rail and guide rail platform is decreased, reduces friction, accelerates scattered
Heat, improve the service life of rotating shuttle
As it is further preferred that the oblique export groove of the rubbish extends simultaneously from the upper surface of annular shuttle frame guide rail towards direction is screwed out
Connection is on the lower surface of annular shuttle frame guide rail.The oblique export groove of rubbish is on the outer ring surface of annular shuttle frame guide rail towards back-out side
To during extension, dirt is carried over after the oblique export groove of rubbish advances downwardly automatically when shuttle race rotates and smoothly excluded.
Preferably, stretching out to form blowdown breach in Sediment trap corresponding with the moon circle, blowdown breach is again outside
Extend and connect on the outer ring surface of moon circle.By setting the blowdown connected with Sediment trap to lack on shuttle race corresponding with enclosing the moon
Mouthful, accumulating in the dirt in Sediment trap can discharge outside rotating shuttle at any time in the presence of centrifugal force, without manual clear, time saving province
Power.
As it is further preferred that being folded with wool felt between the outer ring surface of the moon circle and shuttle race.The moon circle and shuttle race between sandwiched
Wool felt, lubrication enough between shuttle frame and shuttle race can be ensured by wool felt adsorption storage lubricating oil.
Preferably, the shuttle race surface corresponding with the shuttle frame end face is provided with several oil storage tanks, oil storage tank is by oozing
The connection of oily passage with the track you face of annular shuttle frame guide rail interworking.Pass through the inner surface setting oil storage tank in shuttle race, shuttle
During bed rotation, lubricating oil realizes internal auto-supply i.e. from oil storage tank auto-pumping to track you face.
Preferably, the medial extremity of the Sediment trap connects the inner ring surface of shuttle race, outboard end is towards the screw-in side of shuttle race
To extending and connect in the inner port of blowdown breach.The bearing of trend of Sediment trap towards shuttle race screw-in direction when, dirt exists
Shuttle race carries over Sediment trap medial extremity when rotating slides to blowdown breach and discharged automatically.
Therefore, the lubrication pollution discharge structure tool of sewing-machine rotating shuttle shuttle frame guide rail of the present utility model has the advantage that：By
The axially extending bore or non-metallic wear resistant layer turned in upper and lower end face is set on annular shuttle frame guide rail, frictional resistance can be reduced, axially
Through hole and can accelerates radiating, while and can storage lubricating oil, ensures profit permanently effective between annular shuttle frame guide rail and track platform
It is sliding, improve service life；Sediment trap and blowdown breach are set by the surface of in-orbit platform where rites are performed, rubbish is set on annular shuttle frame guide rail
The oblique export groove of rubbish, can be such that caused dirt in production process is automatically drained out outside rotating shuttle；Store by the inner surface setting in shuttle race
Oil groove, lubricating oil is set to realize the auto-supply inside rotating shuttle from oil storage tank auto-pumping to track you face.
