Description
Technical field
The present invention relates in technical field of sewing machines, it is particularly suitable for a kind of double drive right side head of sewing machine.
Background technique
Full-automatic head of sewing machine part is all to drive needle to move up and down by a motor, while driving presser feet at present
Movement, needle move up and down and realize the function of sewing by cooperating with rotating shuttle, and presser feet realizes the function of feeding by cooperating with feed dog
Energy.Existing machine can only carry out feeding and sewing to cloth, cannot carry out feeding to steel band；If to sew to steel band,
It then cannot achieve and feeding carried out to steel band.
Summary of the invention
In place of overcoming above-mentioned the deficiencies in the prior art, a kind of double drive right side sewing machine is provided
Head, the head of sewing machine are driven using presser feet and separate driving with needle up and down motion, realize that sewing separately drives with steel band feeding,
So as to separately control sewing and steel band.Start when, by presser feet drive steel band feeding, but sew driving not into
Row movement, realizes only need feeding without sewing at this time, while presser feet send steel band to be not only able to achieve to send steel band forward, and also
It is able to achieve and send steel band backward.
The purpose of the present invention is what is be achieved through the following technical solutions:
Head of sewing machine on the right side of a kind of double drive, including main shaft, presser feet drive shaft, presser feet move forward and backward drive shaft, above and below presser feet

To plate, presser feet driving swing rod, promote connecting rod, needle bar guide pin bushing, big presser foot block, three connecting rods, thread take-up cam, thread take-up tension lever, take-up company
Bar, line-choosing connecting rod pin, thread take-up crank, shank connecting rod, shank fixture block, lower guideway, lower guideway sliding block 1, upper rail, lower guideway are sliding
Block 2, upper rail sliding block, presser feet move forward and backward eccentric wheel, presser feet moves forward and backward connecting rod of eccentric wheel, move forward and backward holder, transport up and down
Movable eccentric wheel, up and down motion connecting rod of eccentric wheel, up and down motion holder.
The transmission input is main shaft and presser feet drive shaft, the two are the input terminal of driving respectively.Main shaft is by choosing
Line cam drives thread take-up tension lever to realize and acts to the take-up of line, drives the shank equipped with needle or more by thread take-up crank, shank connecting rod
Movement.
The loose ends cylinder is mounted on loose ends cylinder mounting block.
The clamp is mounted on clamp cylinder, and clamp cylinder is mounted on clamp cylinder mounting block；Presser feet driving
By driving presser feet to move forward and backward eccentric wheel on axis, connecting rod of eccentric wheel driving is moved forward and backward by presser feet and moves forward and backward holder drive
Presser feet moves forward and backward drive shaft swing.
Big presser bar equipped with big presser feet is mounted on lower guideway and lower guideway sliding block 1.
Shank and small presser bar equipped with small presser feet can move up and down in needle bar guide pin bushing, and needle bar guide pin bushing is mounted on upper rail
And lower guideway sliding block 2.
The advantages of the present invention are:
The present invention overcomes presser feet and sewing drivings independently, and presser feet can be realized the problem to steel band feeding, pass through the above mechanism
Design, it can be achieved that presser feet driving drives with shank sewing separates, and can independent control；It can be achieved to hand over before and after size presser feet
For movement, feeding is realized；The function of upper thread clamp can be realized by cylinder；Loose ends function can be carried out to thread-loosening device by cylinder
Energy；Sewing quality and precision can be improved, can independently drive, apply easier, quick.
