Specific implementation mode
Illustrate that embodiments of the present invention, those skilled in the art can be by this explanations by particular specific embodiment below Content disclosed by book understands other advantages and effect of the present invention easily.
It please refers to Fig.1 to Fig.3.It should be clear that structure, ratio, size etc. depicted in this specification institute attached drawing, only to Coordinate the revealed content of specification, so that those skilled in the art understands and reads, being not limited to the present invention can be real The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size It is whole, in the case where not influencing the effect of present invention can be generated and the purpose that can reach, should all still fall in disclosed skill In the range of art content can cover.Meanwhile in this specification it is cited as "upper", "lower", "left", "right", " centre " and The term of " one " etc. is merely convenient to being illustrated for narration, rather than to limit the scope of the invention, relativeness It is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the present invention.
As shown in Fig. 2, the present invention provides a kind of lift tooth material feeding driving mechanism of sewing machine comprising lift tooth driving mechanism and Material feeding driving mechanism, lift tooth driving mechanism include lifting the driving motor 17 of dental assembly and Double-directional rotary, and lift dental assembly includes retainer 18 and the lift tooth eccentric wheel 20 that is connected with retainer 18, as shown in Figure 3, the lift tooth eccentric wheel 20 is fixed on driving motor 17 It on output shaft 171, is rotated with output shaft 171, and retainer 18 is driven to move up and down;Material feeding driving mechanism includes and sewing machine The connected main shaft 1 of spindle motor 13, and the feed spool 16 being connected, the feeding are driven by transmission mechanism with the main shaft 1 Axis 16 is fixedly linked with the retainer 18, and feed spool drives retainer to be moved forward and backward in horizontal direction.Tooth driving mechanism is lifted in the present invention Using driving motor 17, is directly moved and be connected with retainer axis using the output shaft 171 of driving motor, realize the fortune up and down of retainer 18 It is dynamic, and the rotation of main shaft 1 drives the rotation of feed spool, realizes the front-rear reciprocation movement of retainer 18, it follows that retainer up and down It moving and moves forward and backward and driven by independent motor, the two is independent of each other, and can quickly adjust the lift tooth amount of retainer, thus and Feed spool is coordinated, and reaches the feeding track for changing the feeding tooth on retainer, to adapt to different sewings;The lift tooth of the present invention Material feeding driving mechanism, total is simple, and installation accuracy is high.
To realize that above-mentioned lift tooth eccentric wheel 20 and the axle power of retainer 18 are driven, the end of retainer 18 and the one of lift tooth rocking arm 19 End is connected, and the other end and the lift tooth eccentric wheel 20 of lift tooth rocking arm 19 are rotatedly connected.For more directly transmission, above-mentioned lift tooth eccentric wheel There is connecting shaft, lift tooth rocking arm 19 there is connection bearing 21, the connecting shaft rotation to be placed in connection bearing 21 on 20.This implementation Connecting shaft is set on tooth eccentric wheel 20 by lifting in example, installation connection bearing 21, passes through company in the other end of lift tooth rocking arm 19 The power transmission of lift tooth eccentric wheel 20 and retainer 18 is realized in the cooperation of spindle and connection bearing 21.
Above-mentioned driving motor 17 is stepper motor in the present embodiment.
For moving forward and backward for retainer is better achieved, above-mentioned transmission mechanism includes the feeding eccentric wheel being fixed on main shaft 1 14, and the feeding connecting rod 15 hinged with feeding eccentric wheel 14, the feeding crank hinged with feeding connecting rod 15, feeding crank with give Material axis 16 is fixedly linked.The rotation of main shaft 1 drives the rotation of feeding eccentric wheel 14 in the present embodiment, and then passes through feeding connecting rod 15 It moves up and down, by the feeding crank being hinged on feeding connecting rod 15, drives the rotation of feed spool 16 in a certain range, The rotation of feed spool 16, to realize moving forward and backward for retainer.
The present invention also provides a kind of sewing machines, the lift tooth material feeding driving mechanism with sewing machine as described above.This hair Bright sewing machine cloth feeding moves:The rotation of spindle motor 13 drives main shaft 1 to rotate, and the rotation of main shaft 1 drives feeding eccentric wheel 14 Rotation, the rotation of feeding eccentric wheel 14 drives feeding connecting rod 15 to move up and down, by being hinged on feeding connecting rod 15 Feeding crank drives the rotation of feed spool 16 in a certain range, the rotation of feed spool 16, to realize the front and back fortune of retainer 18 It is dynamic, that is, realize the front-rear reciprocation movement of feeding tooth on retainer.And the rotation of driving motor 17, by output shaft 171 by power It is transferred directly to retainer 18, to realize the tooth of the lift up and down movement of feeding tooth on retainer 18.
In conclusion the lift tooth material feeding driving mechanism of the sewing machine of the present invention, can quickly adjust the lift tooth amount of retainer, from And coordinated with feed spool, reach the feeding track for changing the feeding tooth on retainer, to adapt to different sewings;The present invention's Tooth material feeding driving mechanism is lifted, total is simple, and installation accuracy is high.So the present invention effectively overcomes in the prior art kind It plants disadvantage and has high industrial utilization.
