Specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
As Figure 1-Figure 4, the present invention discloses a kind of neckline sewing machine, including sewing machine stand 1, is set to the sewing machine
Sewing machine head 2 on frame 1 is set on the sewing machine stand 1 for annular collar to be carried out to the positioning conveying group of localized delivery
Part is additionally provided with the doubling mechanism for annular collar to be carried out to doubling sewing on the sewing machine stand 1;
The positioning conveying assembly include the active transmission mechanism for being set to 2 side of sewing machine head, be set to it is described
2 other side of sewing machine head struts conveying mechanism, is set to the active transmission mechanism and described struts between conveying mechanism
Tensioning regulating mechanism, the active transmission mechanism includes the delivery roll 4 of one group of parallel rotation setting, and the delivery roll 4 is by electricity
Machine driving rotation, it is described strut conveying mechanism include the mounting base 5 being fixedly installed on the sewing machine stand 1, one end rotation set
The bending-type swing rod 6 that is placed in the mounting base 5, be rotatably dispose in 6 other end of bending-type swing rod strut conveying roller 7,
The equal horizontal extension of rotational axis line for strutting conveying roller 7 and the bending-type swing rod 6, the bending-type swing rod 6 and institute
The locking mechanism for being provided between mounting base 5 and the two being locked in multiple operating positions is stated, the tensioning regulating mechanism includes edge
The tensioning cylinder 9, horizontal that slides of sliding block 8, the driving sliding block 8 of up and down direction and 1 phase of sewing machine stand sliding setting
The nutted rod 10 being fixedly installed on the sliding block 8, the tensioning conveying roller 11 being rotatably dispose on the nutted rod 10, described
Limition orientation mechanism is provided between tight bar 10 and the sewing machine stand 1;
