Abstract
The utility model belongs to the technical field of sewing machines, and particularly relates to an outer pressing pin device of a sewing machine. The outer pressing pin device of the sewing machine comprises an air cylinder arranged at a machine head of the sewing machine and located at one side of a needle rod. The outer end of an air cylinder rod of the air cylinder is connected with an outer pressing pin. The air cylinder rod stretches and retracts so that the outer pressing pin can be driven to move vertically. An air cylinder rod guide device is arranged at one side of the air cylinder. According to the outer pressing pin device of the sewing machine, the operation that a template is pressed by the two hands can be replaced, especially in the process that materials such as cotton-padded clothes and a down-filled coat which are low in density and soft are sewn; the stability of the guide device is high and it is guaranteed that in the sewing process, the template can be pressed and a sewn article can be pressed more stably; the travel reaches 15mm, it is guaranteed that the template is convenient to take and place and it is further guaranteed that when the outer pressing pin is lifted and moved in a non-contact mode, the phenomenon that the outer pressing pin knocks down the template due to the fact that the lifting height of the outer pressing pin is small is avoided; an independent pressure reducing valve is arranged so that the air pressure of a large pressing pin can be adjusted and when the height of the sewn materials is not uniform, it is effectively guaranteed that the outer pressing pin can float vertically as if a spring is arranged, the template does not deviate, and the outer pressing pin device is suitable for various sewing machines with the requirement for the template in the sewing process.

Above-mentioned cylinder rod guider is: on the lateral surface of cylinder body, be provided with the chute parallel with cylinder rod axis, the outer end of presser feet mounting bracket is provided with and chute guide rail one to one outside, and guide rail is arranged in chute.
Above-mentioned cylinder is connected on head by connecting plate.
Above-mentioned cylinder is connected with Sewing machines controller by air pressure regulator independently.
The utility model compared to existing technology outstanding advantage is:
1, the utility model can replace both hands pressuring template, particularly makes low, the softer material of density (as cotton dress, eider down outerwear);
2, guider stability of the present utility model is high, can guarantee to suppress template to compress and to make thing more quietly in sewing process;
3, the utility model stroke reaches 15mm, and larger stroke can guarantee that template picks and places conveniently, also can guarantee to move Shi Buhui and knock template down because external pressure feet lifting plays insufficient height lifting outer presser feet sky;
4, the minimum point of the outer presser feet of the utility model can regulate by trip bolt;
5, the utility model is equipped with independently pressure-reducing valve, and adjustable large presser feet air pressure, when sewing has height, can guarantee that outer presser feet can fluctuate as having filled spring effectively, is unlikely to compress and make article tightly, causes template positioning.
Accompanying drawing explanation:
Fig. 1 is that the utility model is arranged on one of schematic perspective view on head;
Fig. 2 be the utility model be arranged on schematic perspective view on head two.
The specific embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-2:
A kind of outer foot device of Sewing machines, comprise the cylinder 30 that is arranged on head of sewing machine 10 and is positioned at shank 20 1 sides, the outer end of the cylinder rod 32 of cylinder 30 is connected with outer presser feet 40, the flexible drive external pressure pin 40 of cylinder rod 32 moves up and down, the other end of outer presser feet 40 extends to the below of shank 20, in a side of cylinder 30, is provided with cylinder rod guider 50.Stroke reaches 15mm, and larger stroke can guarantee that template 90 picks and places conveniently, also can guarantee to move Shi Buhui and knock not template 90 down because of outer presser feet 40 raising heights lifting outer presser feet 40 skies.
