Background technology
At present, the cutting facility for the sewing device that in the market occurs, sets knife rest typically at sewing device head, by
This configures fixed and moving cutter, eccentric stiffener is set on knife rest and by linkage, the dynamic cutter of drive, which back and forth ships to reach, to be cut
Line purpose.The reciprocating motion of its cutter is essentially all to provide power by the main shaft of sewing device, i.e., dynamic cutter is set with sewing
Standby main shaft is synchronized with the movement, even if trimming requirement is not required at this time.Therefore, under the continuous trimming action of cutter group, not only produce and make an uproar
Sound, also makes the relevant group year of cutter group easily produce abrasion, substantially reduces service life.Then, although the most of the time simultaneously
Trimming is not required, therefore causes the waste of electric energy.
Utility model content
The purpose of this utility model is to provide a kind of energy saving, simple in structure tangent line for self-feeding sewing system
Adjust structure.
A kind of tangent line for self-feeding sewing system adjusts structure, including：Fixed seat, the fixation in fixed seat
Blade, and the movable blades being actively coupled with fixed seat；Further include the actuating unit and driving mechanism for driving movable blades；
The actuating unit includes the force piece being fixed in fixed seat, and the tangent line being connected between force piece and movable blades pushes away
Bar, the tangential cam of driving and the connection tangent line push rod, tangent line driving crank；The driving mechanism includes tangent line electromagnetism iron-based
Disk, the tangent line electromagnet being installed on the tangent line electromagnet basal disc, the clutch push rod by the tangent line solenoid actuated, cunning
Swing arm, wherein, the travelling arm couples with tangent line driving crank, and the clutch push rod couples with tangential cam.
Further, line covering is additionally provided with the fixed blade.
Further, the driving mechanism further includes the fastener coupled with clutch push rod, firm part push rod.
Further, the tangent line electromagnet is installed on the tangent line electromagnet basal disc by fixed screw and housing pin
On.
Driving mechanism work in the tangent line adjustment structure for self-feeding sewing system of this case, movable blades can be with
Tangential cam revolution, the reciprocating rotation back and forth of the movable blades on tangent line push rod, makes movable blades cooperate with fixed blade
The end of a thread is sheared, is easier to operate, and precision is high, component that can be independent as one is installed on sewing machine, can be only
Vertical work, is applicable in a variety of sewing machine structures, and installation is easy, easy to use, compact-sized, small, the saving energy, transmission knot
Structure advantages of simple.
According to the accompanying drawings will be more to the detailed description of the utility model specific embodiment, those skilled in the art
Add the above-mentioned and other purposes, advantages and features of clear the utility model.
Brief description of the drawings
Some specific realities of the utility model are described in detail by way of example, and not by way of limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
What these attached drawings were not necessarily drawn to scale.In attached drawing：
Fig. 1 is the signal of the tangent line adjustment structure for self-feeding sewing system of the utility model one embodiment
Figure.
Embodiment
Referring to Fig. 1, present embodiments provide a kind of tangent line for self-feeding sewing system and adjust structure, including：Gu
Reservation 1, the fixation blade 2 in fixed seat 1, and the movable blades 3 being actively coupled with fixed seat 1；Further include for driving
The actuating unit and driving mechanism of movable blades 3；The actuating unit includes the force piece 41 being fixed in fixed seat 1, and connection
The tangential cam 43 that be connected to the tangent line push rod 42 between force piece 41 and movable blades 3, drives and couple the tangent line push rod 42,
Tangent line driving crank 44；The driving mechanism includes tangent line electromagnet basal disc 51, is installed on the tangent line electromagnet basal disc 51
Tangent line electromagnet 52, the clutch push rod 53, the travelling arm 54 that are driven by the tangent line electromagnet 52, wherein, the travelling arm
54 couple with tangent line driving crank 44, and the clutch push rod 53 couples with tangential cam 43.Preferably, tangential cam 43 with
Retain the gap of 0.5mm between travelling arm 54.
In this case, driving mechanism work, movable blades can be turned round with tangential cam, and the movable blades on tangent line push rod come
Reciprocating rotation is returned, movable blades and fixed blade is cooperated shearing the end of a thread, is easier to operate, and precision is high, can be with
The component independent as one is installed on sewing machine, can be worked independently, and is applicable in a variety of sewing machine structures, and installation is easy,
It is easy to use, compact-sized, small, drive mechanism advantages of simple.
The operation principle of this case is：Tangent line electromagnet 52 drives clutch push rod 53, travelling arm 54 to move back and forth, and drive is cut
Line cam 43 so that the tangent line push rod 42 of driving and connection tangential cam 43 moves, and movable blades 3 can be returned with tangential cam 43
Turn, movable blades 3 on tangent line push rod 42 reciprocating rotation back and forth, makes movable blades 3 and fixation blade 2 mutual by force piece 41
Coordinate shearing the end of a thread.
Line, which is additionally provided with, at fixed blade 2 covers 6.It is that line to be cut off is had good positioning that line, which covers 6, and prevents that line is disorderly.
Driving mechanism further includes the fastener 55 coupled with clutch push rod 53, firm part push rod 56, fastener 55 be with
