Description
Technical field
The utility model relates to the overall transmission mechanism of a kind of bar tacking machine tangent line pipeline purging presser foot lifter, belongs to sewing machine field.
Background technology
Bar tacking machine mainly carries out noose to the limit of cloth, avoids cloth edge plucking.After selvedge noose completes, tangent line, then pipeline purging, then lift presser feet, cloth is taken out.The tangent line of prior art bar tacking machine, pipeline purging and each free power transmission of presser foot lifter three actions, cause bar tacking machine head internal structure complicated, and assembling trouble, cost is large.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, thering is provided a kind of adopts power to control the work schedule of tangent line, pipeline purging and presser foot lifter by gear drive three cams, ensure accuracy and the reliability of three actions, complete the overall transmission mechanism of bar tacking machine tangent line pipeline purging presser foot lifter of noose sewing operation.
The technical scheme of the overall transmission mechanism of the utility model bar tacking machine tangent line pipeline purging presser foot lifter is: it is characterized in that comprising the cam bearer be arranged in bar tacking machine head, in cam bearer, camshaft is installed, camshaft is installed and lifts belling wheel, pipeline purging cam and tangential cam, lift belling wheel a sidewall on travelling gear is installed, install at the outer wall of cam bearer and drive power, the output shaft of power is driven to be meshed with travelling gear by driven wheel, the top of cam bearer is installed and is lifted pressure cam lever shaft, lift installation on pressure cam lever shaft and lift pressure driving crank and pipeline purging driving crank, lift installation on pressure driving crank and lift pressing roller, lift pressing roller and lift belling and take turns and match, pipeline purging driving crank is installed pipeline purging roller, pipeline purging roller matches with pipeline purging cam, tangential cam bar axle is installed in the side of cam bearer, tangential cam bar axle installs tangent line driving crank, tangent line driving crank is installed tangent line roller, tangent line roller matches with tangential cam.
The overall transmission mechanism of bar tacking machine tangent line pipeline purging presser foot lifter of the present utility model, when bar tacking machine Job readiness, drive dynamically working, drive driven wheel rotates to an angle, driven wheel band nutating gear, travelling gear drive is lifted belling wheel rotation extruding downwards and is lifted pressing roller, make to lift the presser feet arm system that pressure driving crank pulls machine, lift presser feet, so that putting of cloth, then, after bar tacking machine is started working, drive power rotation certain angle, drive is lifted belling wheel and is lifted pressure drive rod crank, presser feet arm system is made to push down cloth, carry out bartacks work.After a noose sewing terminates, drive dynamic rotation to drive tangential cam to rotate, tangential cam promotes tangent line driving crank and swings certain angle, promotes the work of machine tangent mechanism by tangent line roller, cuts off suture; Then pipeline purging cam rotates through pipeline purging driving crank and pipeline purging roller, drives pipeline purging driving crank to pull pipeline purging institution staff, pulls out surface sweeping line, finally, lift belling wheel rotation drive and lift the action of pressure driving crank, pull the presser feet arm system of machine to unclamp cloth, whole noose sewing work completes.Compared with the prior art, this programme will be lifted belling wheel, pipeline purging cam and tangential cam and be arranged on same camshaft, and by a power drive, drive is lifted pressure driving crank, pipeline purging driving crank and tangent line driving crank and is swung, thus the foot lifting mechanism of band movement machine, tangent mechanism and pipeline purging institution staff, action is accurate, stable, simplifies head internal structure, reduces production cost.
The overall transmission mechanism of bar tacking machine tangent line pipeline purging presser foot lifter of the present utility model, described driving power can be stepper motor or impulse motor.
Accompanying drawing explanation
Fig. 1 is the overall transmission mechanism exploded perspective view of the utility model bar tacking machine tangent line pipeline purging presser foot lifter.
Detailed description of the invention
The utility model relates to the overall transmission mechanism of a kind of bar tacking machine tangent line pipeline purging presser foot lifter, as shown in Figure 1, comprise the cam bearer 1 be arranged in bar tacking machine head, camshaft 2 is installed in cam bearer, camshaft is installed and lifts belling wheel 3, pipeline purging cam 4 and tangential cam 5, lift belling wheel 3 a sidewall on travelling gear 6 is installed, install at the outer wall of cam bearer 1 and drive power 7, the output shaft of power 7 is driven to be meshed with travelling gear 6 by driven wheel 8, the top of cam bearer 1 is installed and is lifted pressure cam lever shaft 9, lift installation on pressure cam lever shaft and lift pressure driving crank 10 and pipeline purging driving crank 11, lift installation on pressure driving crank 10 and lift pressing roller 12, lift pressing roller 12 and lift belling and take turns 3 and match, pipeline purging driving crank 11 is installed pipeline purging roller 13, pipeline purging roller 13 matches with pipeline purging cam 4, tangential cam bar axle 15 is installed in the side of cam bearer 1, tangential cam bar axle 15 installs tangent line driving crank 16, tangent line driving crank 16 is installed tangent line roller 17, tangent line roller 17 matches with tangential cam 5.When bar tacking machine Job readiness, power 7 is driven to work, driven wheel 8 is driven to rotate to an angle, driven wheel 8 is with nutating gear 6, travelling gear drive is lifted belling wheel 3 rotation extruding downwards and is lifted pressing roller 12, make to lift the presser feet arm system that pressure driving crank 10 pulls machine, lift presser feet, so that putting of cloth, then, after bar tacking machine is started working, power 7 is driven to turn round certain angle, drive is lifted belling wheel 3 and is lifted pressure drive rod crank 10, makes presser feet arm system push down cloth, carries out bartacks work.After a noose sewing terminates, drive power 7 to rotarily drive tangential cam 5 and rotate, tangential cam 5 promotes tangent line driving crank 16 and swings certain angle, promotes the work of machine tangent mechanism by tangent line roller 17, cuts off suture; Then pipeline purging cam 4 rotates through pipeline purging driving crank 11 and pipeline purging roller 13, pipeline purging driving crank 11 is driven to pull pipeline purging institution staff, pull out surface sweeping line, finally, lift belling wheel 3 rotation drive and lift the action of pressure driving crank 10, pull the presser feet arm system of machine to unclamp cloth, whole noose sewing work completes.Compared with the prior art, this programme will be lifted belling wheel 3, pipeline purging cam 4 and tangential cam 5 and be arranged on same camshaft, and by a power drive, drive is lifted pressure driving crank 10, pipeline purging driving crank 11 and tangent line driving crank 16 and is swung, thus the foot lifting mechanism of band movement machine, tangent mechanism and pipeline purging institution staff, action is accurate, stable, simplifies head internal structure, reduces production cost.Described driving power 7 can be stepper motor or impulse motor.
