Position eccentric wheel 700 is in storage tank, while can be covered on storage tank that a panel is set, when winding operation need not be carried out, panel
It is covered on storage tank, winding mechanism of sewing machine is not exposed at outside casing, is prevented effectively from independent, the outside sewing machine coiling for setting
Mechanism forms to production process and disturbs, it is ensured that the operating efficiency and work stability and reliability of sewing machine, and sewing machine is overall outer
Type smooth-going is smooth, brief attractive in appearance.When winding operation is carried out, panel is opened, peg or spindle 100 is fixed on upper end, then covered
Top panel, stirs shifting fork mechanism, connecting rod 300 is swung along rivet 301, passes through connecting rod 300 due to roll 502 so even
Coiling axis mechanism is driven to swing and make coiling axis mechanism inconsistent with bevel gear mechanism when bar 300 swings, the ring of coiling axis mechanism
Shape rubber ring 501 can be rotated with the rotation of bevel gear 402, be hidden in the peg or spindle 100 in storage tank with coiling axis mechanism
Rotate and rotate and carry out winding operation, peg or spindle 100 is concealed in storage tank, and place is not take up completely, nor affects on sewing machine
Normal sewing work, improve the operating efficiency of sewing machine, simple structure is reasonable in design and novel, is hidden in casing and accommodating
Winding mechanism of sewing machine in groove, the overall architecture of sewing machine is not influenceed so that sewing machine outer type is brief attractive in appearance.
Other winding mechanism of sewing machine of the present utility model changes traditional structural style, annular rubber ring in traditional structure
501 directly offset with the side wall of the master gear on main shaft is connected so that annular rubber ring 501 turns with the rotation of master gear
It is dynamic, mutually rotated by rubbing between annular rubber ring 501 and master gear, such structure, it is susceptible to skid, dallies
Phenomenon, influences winding efficiency, and annular rubber ring 501 easily to wear and tear, and service life is short.Sewing machine coil winding machine of the present utility model
Structure, is rotated on support 200 and fixes a bevel gear mechanism, and bevel gear 402 and the driven gear on main shaft of bevel gear mechanism are nibbled
Close so that bevel gear 402 rotates with the rotation of main shaft, bevel gear 402 tightly engages with driven gear, will not connect
The phenomenons such as bad, idle running, skidding are touched, job stability is high, long service life.Annular rubber ring 501 on roll 502
Can mutually be butted on bevel gear 402 and be rotated with the rotation of bevel gear 402, annular rubber ring 501 can also depart from bevel gear 402 with
Realize the clutch effect between annular rubber ring 501 and bevel gear 402.A connecting rod 300, connecting rod 300 1 are additionally provided with support 200
End is rotated with support 200 by rivet 301 and is connected, and the other end is rotated with roll 502 by a latch 505 and is connected, support 200
The spacing breach 201 for being available for roll 502 to pass through and being available for roll 502 to be swung with connecting rod 300 is provided with, when connecting rod 300
Roll 502 swings in spacing breach 201 with connecting rod 300 when being swung along rivet 301, can be stirred by shifting fork mechanism
Connecting rod 300 is swung so as to realize the clutch effect between annular rubber ring 501 and bevel gear 402, simple structure, it is reasonable in design and
It is novel.
When external force acts on shifting fork mechanism, and connecting rod 300 is stirred by the shift fork 601 that commutates swing, roll 502 is with even
The swing of bar 300 and swing in the spacing breach 201, the annular rubber ring 501 being also secured on bottom is mutually butted on cone tooth
Take turns to realize the splicing results between annular rubber ring 501 and bevel gear 402 on 402 lateral walls, annular rubber ring 501 can be with cone
The rotation of gear 402 and rotate, while roll 502 is rotated with the rotation of annular rubber ring 501, blocked by jump ring 504
Gu the peg or spindle 100 in upper end is rotated with the rotation of roll 502, the winding operation of peg or spindle 100 is finally completed.Work as peg or spindle
100 coiling amounts reach it is a certain amount of after, peg or spindle 100 is inconsistent with spacing eccentric wheel 700, with the continuous increasing of the coiling amount of peg or spindle 100
Plus, the interaction force between peg or spindle 100 and spacing eccentric wheel 700 is bigger, and spacing eccentric wheel 700 is fixed on support 200, Gu
It is fixed motionless, therefore with the continuous increase of interaction force, peg or spindle 100 is moved towards the direction away from spacing eccentric wheel 700, i.e.,
Roll 502 is moved so that annular rubber ring with the increase of the coiling amount of peg or spindle 100 towards the direction away from bevel gear mechanism
501 depart from bevel gear mechanism to realize the dialysis effect between annular rubber ring 501 and bevel gear 402, are finally stopped peg or spindle 100
Winding operation, realizes that automation is stopped.Easy to operate, threading speed is fast, and peg or spindle 100 is fixed in upper end by jump ring 504
Portion, the phenomenon, stable and reliable in work, practical, Er Qie such as will not dally between roll 502 and peg or spindle 100, skid
In the presence of spacing eccentric wheel 700, roll 502 can be with the increase of the coiling amount of peg or spindle 100 towards away from bevel gear mechanism
Direction is moved so as to make annular rubber ring 501 automatic in full line away from bevel gear mechanism and then stop the winding operation of peg or spindle 100,
Stopping winding operation being automated, high degree of automation, performance is superior, high working efficiency.
Therefore, a kind of built-in winding mechanism of sewing machine of the present utility model solves existing winding mechanism of sewing machine
Complex structure, volume are big, inefficiency, automaticity are low, poor work stability problem, realize simple structure and body
Product is small, reasonable in design and novel, and built-in, parts are few, low production cost, high degree of automation, and performance is superior etc.
Beneficial effect.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
The equivalent structure transformation that every utilization the utility model specification and accompanying drawing content are made, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
