Since eedle penetrates relatively short distance it is necessary to realize that compress presser feet 8 is fully depressed by, at this point, the rotational angle of centering block 22
Very small, the present invention amplifies angle by speed increasing mechanism, to reduce cam 5 for the shock loading of cam bawl 17.
The present invention is provided with the input shaft 3 of control speed increasing mechanism on the fixation bottom plate 7 and centering block 22 rotates synchronously
Clutch.It may be implemented to carry out compress when needed by clutch, without compress when unwanted.
Specifically, the clutch includes electromagnet 23, and the electromagnetism mandrel 24 of electromagnet 23 passes through connector 25 and clutch
Bar 26 connects, and trip(ping) lever 26 is an integral structure with connector 25 or split type structure.Trip(ping) lever 26 is arranged in clutch end cover
On 27, trip(ping) lever 26 is axial without translation freedoms, can rotate automatically.Clutch end cover 27 is being put by the setting of guide post 28
On block 22, connection-peg 29 and inserting groove 30, electromagnetism mandrel is respectively set in the end adjacent with input shaft 3 of clutch end cover 27
24 flexible drive clutch end cover 27 is towards input shaft 3 or far from the mobile connection realized with input shaft 3 of input shaft 3 or divides
From.
The connection-peg 29 of the present embodiment is located on clutch end cover 27, and accordingly, inserting groove 30 is located on input shaft 3.It inserts
Connector 29, inserting groove 30 position also can be interchanged, be able to achieve clutch end cover 27 and connect with input shaft 3.For convenience
Connection, the head of connection-peg 29 is at pointed.After connection, clutch end cover 27 will be rotated synchronously with input shaft 3, therefore, connection-peg
29 be polygonized structure, such as flower pattern, rectangular, triangle, and inserting groove 30 and the shape of connection-peg 29 match.Work as electromagnetism
When iron 23 is attracted, electromagnetism mandrel 24 is driven, clutch end cover 27 is mobile towards centering block 22 until connection-peg 29 is plugged in inserting groove
When in 30, then it can be realized active speed increasing gear 12 and centering block 22 rotate synchronously.
In addition, cylinder, small-sized electric push rod etc. can be used for the electromagnet 23 instead of the present embodiment, play identical
Effect.
The structure of clutch is also possible to that the pillar with external tooth is arranged on centering block 22, on the input shaft 3 of speed increasing mechanism
One end adjacent with centering block 22 is also provided with outer toothed portion, and pillar, input shaft 3 are coaxially set, in the outer toothed portion of pillar, input shaft 3
It is arranged with tooth set outside, tooth set is moved axially by solenoid actuated, (the connection when tooth covers the outer toothed portion of connection pillar, input shaft 3
State), centering block 22 and input shaft 3 rotate synchronously, when tooth set is located in the outer toothed portion of pillar or input shaft 3 (discrete state),
Input shaft 3 is not rotated synchronously with centering block 22.When using the clutch configuration, input shaft 3 is a hollow shaft.Input shaft 3, centering block
22 are set in same root inner shaft.
It includes in the embodiment of centering block 22 that above-mentioned clutch configuration, which is applied to bindiny mechanism,.When bindiny mechanism is song
It is equally applicable when handle slide block mechanism.
Further, rotating wheel 9 of the present invention is rotation synchronous pulley, is provided with driving wheel in the shaft of motor 11,
Driving wheel and rotation synchronous pulley and between connected by synchronous belt 31.Motor 11 is arranged on pedestal 32, pedestal 32 and rotation
Wheel seat 10 connects.The pedestal 32 of the present embodiment is an integral structure with rotation wheel seat 10.Pedestal 32 is fixed on baseplate of sewing machine 33
On.Due to being relatively large in diameter for rotation synchronous pulley, in order to increase synchronous belt 31 and rotate the contact area between synchronous pulley,
Ensure that synchronous belt 31 is able to drive rotation synchronous pulley rotation, is set on the pedestal 32 between rotation synchronous pulley and motor 11
Roller 34 is limited there are two setting.In order to facilitate tensioning synchronous belt 31, the motor 11 is arranged on motor mount 35, in electricity
Strip-shaped hole 36 is set in machine mounting base 35, adjusts position of the motor mount 35 on pedestal 32 to be tensioned synchronous belt 31.
In addition to synchronous belt drive mechanism, gear drive can also be used, correspondingly, rotating wheel 9 is ring gear,
Setting is by driving gear, driving gear and ring gear engaged transmission in the shaft of motor 11.
The working principle of the invention is:
Shank 1 drive swing rod 2 swing, swing rod 2 swing by speed increasing gear speedup after, band moving cam 5 rotate, cam 5
8 compress of compress presser feet is driven according to certain timing.Due to gear installation base 6, fixed bottom plate 7 be arranged on rotating wheel 9 and with
Rotating wheel 9 rotates synchronously, and motor 11 drives rotation synchronous pulley rotation by synchronous belt 31.When the eedle of shank 1 penetrates cloth
When in 38, the synchronous compress of compress presser feet 8, motor 11 drives compress presser feet 8 to turn an angle centered on the axis of shank 1,
It realizes the rotation of cloth, and then realizes automation curve sewing during sewing.
The method that the present invention directly drives cloth-pressing device using shank 1, this method only need to be mounted on seam using auxiliary equipment
It threads on machine, does not need to carry out any repacking to sewing machine, can either realize the compress material during sewing, greatly reduce into
This, improves utilization rate of equipment and installations.Meanwhile by mechanical device directly by the power-conversion of eedle be cloth-pressing device power, no
It only ensure that the reliability and precision of timing, and react in time, the efficiency of curve automatic sewing can be greatlyd improve.
Above-described embodiment is only one of presently preferred embodiments of the present invention, and but not intended to limit the scope of the present invention,
Therefore: the equivalence changes that all shape, structures under this invention, principle are done should all be covered by within protection scope of the present invention.
