Abstract
The utility model relates to an upper synchronous feeding mechanism and a lower synchronous feeding mechanism for a thin material sewing machine. The upper synchronous feeding mechanism and the lower synchronous feeding mechanism are designed to solve the problem that similar products are difficult to adjust and the feeding synchronous difficulty is high. The upper synchronous feeding mechanism and the lower synchronous feeding mechanism are characterized in that an upper pin shaft hole of an upper feeding swing plate base is installed on a machine casing of the sewing machine through a pin shaft, and when swinging around the pin shaft, the upper feeding swing plate base drives the upper synchronous feeding mechanism to change the swing amplitude and change the stroke of upper feeding teeth; and a lower feeding swing plate base swings around the pin shaft swings around the pin shaft to drive a lower feeding mechanism to change the swing amplitude and change stroke of lower feeding teeth. A synchronous connecting rod eccentric pin and a synchronous connecting rod are arranged, so that the upper feeding teeth and the lower feeding teeth perform synchronous movement; and when the error influence of the upper synchronous feeding mechanism and the lower synchronous feeding mechanism occurs, the center distance of the synchronous connecting rod is adjusted through the synchronous connecting rod eccentric pin so that the upper synchronous feeding mechanism and the lower synchronous feeding mechanism can run synchronously. The upper synchronous feeding mechanism and the lower synchronous feeding mechanism are low in manufacturing cost, a feeding method is practicable, labor efficiency is effectively improved, and the upper synchronous feeding mechanism and the lower synchronous feeding mechanism are suitable for being popularized and applied.

The specific embodiment
Embodiment is take the feeding method of thin material flat seam machine synchronous feeding mechanism as example, as shown in Figure 1 to 4, this synchronous feeding mechanism is provided with synchronous feeding mechanism and lower synchronous feeding mechanism, the upper pin hole 1201 that the upper feeding of upper synchronous feeding mechanism swings panel seat 12 is mounted on the (casing of bearing pin described in Fig. 1 and flat seam machine on the casing of flat seam machine by bearing pin, and thin material flat seam machine and electric device are not drawn), when described upper feeding swings panel seat in the time that bearing pin swings, in drive, feed mechanism changes amplitude of fluctuation, the stroke of feeding tooth 24 in change.
The downside pin axis hole 501 that the lower feeding of lower synchronous feeding mechanism swings panel seat 5 is mounted on by bearing pin on the casing of flat seam machine, when described lower feeding swings panel seat in the time that bearing pin swings, drives down charging mechanism to change amplitude of fluctuation, changes the stroke of lower feeding tooth 26.
Synchronising (connecting) rod 11 connects feeding by bearing pin and swings panel seat 12, lower feeding swing panel seat 5, makes described upper and lower feeding swing panel seat and synchronously swings, and realizes the synchronous feeding of upper and lower synchronous feeding mechanism.
Synchronising (connecting) rod cam pin 9 one end are installed and are connected lower feeding swing panel seat 5, the other end is connected to synchronising (connecting) rod 11, directly upper feeding swing panel seat 12, lower feeding are swung to panel seat 5 and connect respectively by synchronising (connecting) rod 11, in the time swinging panel seat 5 swing state, in drive, feeding swings the synchronous swing of panel seat 12, and in interlock, feeding tooth 24, lower feeding tooth 26 are synchronized with the movement.Simultaneously, the upper synchronous feeding mechanism bringing in order to eliminate part's machining errors, lower synchronous feeding mechanism error effect, lower feeding swings panel seat 5 and is provided with synchronising (connecting) rod cam pin 9 with the junction of synchronising (connecting) rod 11, be used for regulating the centre-to-centre spacing of synchronising (connecting) rod 11, make synchronous feeding mechanism, the operation of lower synchronous feeding mechanism synchronously; Described thin material is delivered to and in flat seam machine, is completed next process through lower feed spool 6, upper feed spool 16, upper axle 17.
The course of action of lower synchronous feeding mechanism: in the time that upper axle 17 rotates one week, drive lower feeding connecting rod 19 to swing, the scope that drives long oscillating deck 8 to limit along short oscillating deck 10 swings, the feeding crank 7 that band is automatically connected on long oscillating deck 8 carries out reciprocally swinging, and drive the lower feed spool 6 and the crank of tooth frame 28 that are fixedly connected with it to carry out the swing of equal angular, thereby drive the retainer 27 being connected on crank of tooth frame 28 and the lower feeding tooth 26 being fixedly connected on retainer 27 to move back and forth, completed a feeding circulation.
Simultaneously, in the time that upper axle 17 rotates one week, in drive, feeding connecting rod 18 swings, the scope that in driving, oscillating deck 13 limits along outer oscillating deck 14 swings, the upper feeding rear crank 15 that band is automatically connected on interior oscillating deck 13 carries out reciprocally swinging, and drive the upper feed spool 16 and the upper feeding fork-shaped crank 20 that are fixedly connected with it to carry out the swing of equal angular, thereby the upper feeding balance staff 22 that has driven the front crank 21 of the upper feeding being connected on feeding fork-shaped crank 20 and be fixedly linked with it, upper feeding fork 25, upper feeding retainer 23 and upper feeding tooth 24 move back and forth, complete a upper feeding circulation.
The operation principle of upper and lower synchronous feeding is: in the time needle gage screw rod 2 being screwed into innermost end by stitch length knob 1, needle gage is zero, when now going up axle 17 and rotating, lower feeding tooth 26 can not seesaw, by the connection of synchronising (connecting) rod 11 and the adjusting of synchronising (connecting) rod cam pin 9, upper feeding tooth 24 also keeps identical zero needle gage with lower feeding tooth 26; When needle gage screw rod 2 is during to inner rotary, by the drive of needle gage adjuster 3 and the connecting rod of falling feeding 4, the angle that makes lower feeding swing panel seat 5 progressively strengthens, thereby makes the also progressively increasing of stroke of lower feeding tooth 26; In the time that lower feeding swings panel seat 5 angles increasing, by the drive of synchronising (connecting) rod 11, the angle that makes feeding swing panel seat 12 also synchronously strengthens, the therefore variation of needle gage, and upper synchronous feeding mechanism, lower synchronous feeding mechanism have all kept identical stroke.
