It is further improved to be:Opened on the L-type fixed dam, the L-type slide damper and the doubling core plate
It is provided with installation regulation elongated slot.
It is further improved to be:The pedal for driving the sewing machine head work is provided with the sewing machine stand.
It is further improved to be:It is described strut conveying roller and tensioning conveying roller be provided with spacing ring.
By using preceding solution, the beneficial effects of the invention are as follows:Collar fabric is set in delivery roll, support first
Open and form the transfer rings of closure on conveying roller and tensioning conveying roller, doubling mechanism is by the automatic doubling of collar fabric in addition, then
Sewed in conveying, easy to operate, efficiency high.

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 arranged at the sewing machine
Sewing machine head 2 on frame 1, it is arranged on the sewing machine stand 1 and is used for the positioning conveying group that annular collar is carried out localized delivery
Part, is additionally provided with the doubling mechanism for annular collar to be carried out doubling sewing on the sewing machine stand 1;
The positioning conveying assembly includes being arranged at the active transmission mechanism of the side of the sewing machine head 2, is arranged at the sewing
The opposite side of head 2 strut conveying mechanism, be arranged at the active transmission mechanism and it is described strut between conveying mechanism
Tight governor motion, the active conveying mechanism includes the delivery roll 4 that one group of parallel rotation is set, and the delivery roll 4 is driven by motor
Dynamic to rotate, the conveying mechanism that struts includes that the mounting seat 5, one end being fixedly installed on the sewing machine stand 1 rotation is arranged at
What bending-type swing rod 6 in the mounting seat 5, rotation were arranged at the other end of bending-type swing rod 6 struts conveying roller 7, described
The rotational axis line for strutting conveying roller 7 and the bending-type swing rod 6 is horizontal-extending, the bending-type swing rod 6 and the peace
The locking mechanism that both are locked in multiple operating positions is provided between dress seat 5, the tensioning governor motion is included along upper
The sliding block 8 of setting is mutually slided with the sewing machine stand 1, drives the tensioning cylinder 9, level that the sliding block 8 is slided to fix in lower direction
The tensioning conveying roller 11 that the nutted rod 10 that is arranged on the sliding block 8, rotation are arranged on the nutted rod 10, the nutted rod
Limited location guiding mechanism is set between 10 and the sewing machine stand 1;
The doubling mechanism includes the L-type fixed dam 13 being fixedly installed on the sewing machine stand 1, is slided along horizontal direction
