Description
Technical field
The invention belongs to field of mechanical technique, it is related to a kind of winding mechanism of sewing machine.
Background technology
Sewing machine generally completes cloth sewing by bottom line and upper thread, and the peg or spindle that bottom line is wound with bottom line in shuttle is carried
For, in specific sewing process, temporary transient scarce line situation occurs in peg or spindle, at this moment needs to carry out winding operation to peg or spindle, if
Whole peg or spindle is changed, then excessively wasted, but coiling is then too cumbersome by hand, it is time-consuming to take a lot of work, therefore, on sewing machine generally
Provided with winding mechanism, Automated winding operation is completed by winding mechanism.
Such as Chinese patent application (application number：200910004330.7) a kind of Winder of sewing machine is disclosed, including
The regulation body of bias, the regulation body makes friction pulley be displaced to activation point from resting position, for activating Winder, its
In, regulation body can be without shifting between active position and active position, and pivotable release lever, the release lever and regulation body are rigid
Connection, and including surface can be carried secretly with a ball of string for the wall contacts of the ball of string wound；Wherein, regulation body is formed so that release
The pivot of bar can cause the diameter increase of the ball of string by being wound and regulation body is shifted from active position to non-working position；
Wherein, conjugant is rigidly connected with regulation body and release lever, to pivot jointly, binding site and the regulation body of conjugant
Non-working position is consistent.
The friction pulley of above-mentioned Winder is rotated by being driven with the toothed belt wheel frictional connection in sewing machine drive shaft
Coiling is realized, so that the installation site of whole Winder depends on the position of drive shaft, if be transversely mounted slightly
Offset, shearing abrasion will be produced between friction pulley and toothed belt wheel, friction pulley is easily produced abrasion, has a strong impact on coiling rubber
The service life of rubber tire, influences normal coiling.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of winding mechanism of sewing machine,
The technical problems to be solved by the invention are：The shearing abrasion of friction pulley how is eliminated, service life is improved.
The purpose of the present invention can be realized by following technical proposal：A kind of winding mechanism of sewing machine, sewing machine includes
Casing and the main shaft being rotatably connected on casing, the winding mechanism include peg or spindle axle and are fixed on rubbing for the peg or spindle axle lower end
Wipe wheel, it is characterised in that the winding mechanism also includes being fixed with master on the driven shaft being rotatably connected on casing, the main shaft
Moving gear, one end of the driven shaft is fixed with driven gear, and the driving gear and driven gear are meshed, the driven shaft
The other end be fixed with coiling driving wheel, the casing be additionally provided with can control the friction pulley close to be resisted against coiling driving
On wheel or the clutch component away from coiling driving wheel.
When needing coiling, by bobbin case on peg or spindle axle, by clutch component control friction pulley close to and be resisted against around
On line driving wheel, main axis drives driving gear to rotate, so as to drive driven gear and driven shaft to rotate, is fixed on driven shaft
On coiling driving wheel also concomitant rotation, can be with dynamic friction by the effect of the frictional force between friction pulley and coiling driving wheel
Wheel is rotated, so that peg or spindle axle also concomitant rotation, so as to realize the coiling of peg or spindle.The winding mechanism of this sewing machine by around
One driven shaft and driven gear are set between line driving wheel and driving shaft, so that the driving direction of whole winding mechanism is changed,
Bigger installation and adjustment space can be provided, friction pulley is installed with coiling driving wheel in same axle position, it is to avoid to cut
Friction is cut, the abrasion of friction pulley is reduced, improves service life.
In the winding mechanism of above-mentioned sewing machine, the driving gear and driven gear are helical gear.Pass through two
Helical gear drive mechanism is set, and makes the driving of winding mechanism can be with deflecting, and changes driving direction, using the teaching of the invention it is possible to provide bigger peace
Dress and adjustment space, enable friction pulley to be installed with coiling driving wheel in same axle position, it is to avoid shearing friction, reduce friction
The abrasion of wheel, improves service life.
