Abstract

A cloth pressing foot structure for four-needle six-line two-cutting sewing machine can resolve the problems of prior cloth pressing foot which can not adjust the distance among upper and lower cutters and cloth, to make two outer suture lines not align with the cut edges of the upper and lower cloths respectively when sews two cloths, to reduce sewing strength. The cloth pressing foot is used for four-needle six-line two-cutting sewing machines, which mainly comprises two pressing parts and a guiding space between the two pressing parts, wherein the two pressing parts are respectively provided with a pressing ejector; an adjusting element is provided between the pressing parts and the pressing ejectors; the pressing parts and the adjusting elements are respectively provided with a first joint part and a second joint part which have clutch relationship; therefore, users can assemble the adjusting elements according to cloth thickness to increase or decrease the distance among the upper and lower cutters and the cloth, and the two outer suture lines of sewn cloths can be aligned with the cut edges of the upper and lower cloths respectively, to improve sewing strength and realize beautiful appearance of cloth.

Description

The two compress leg structures of cutting the cloth Sewing machines of four pins, six lines

[technical field]

The compress pin of the relevant a kind of Sewing machines of the utility model refers to a kind of two compress leg structures of cutting the cloth Sewing machines of four pins, six lines that are used for especially.

[background technology]

The sewer had reached the quite skillful stage of technology already, there is more how soon fast easy Sewing machines to be used for producing in a large number ready-made clothes now by factory, make the modern enjoy inexpensive fabric, and early stage Sewing machines tramps with one's feet cooperation people's hand operated with manual type one pin one line profit and finishes, so far most sewing factory all comes the indirect labor with full automatic working, increases production efficiency whereby.

Usually when two blocks of clothes of piece, the width that two blocks of clothes coincide must be suitable with the width that Sewing machines is sewed up, can guarantee that just suture sews in the zone that coincides, and the width that cloth coincides often need be adjusted before cloth is sent into the compress pin through operator, yet, this mode of operation need be dependent on the sewing experience and the proficiency of operator, and sewing machine table is of a great variety on the market, corresponding different platform certainly will will have different adjustment modes, therefore, even if width adjustment and seam width that the veteran operator of sewing all can't coincide cloth exactly are suitable.

In the present existing technology, shown in the publication case of No. the 200837242nd, TaiWan, China, disclosed the structure of traditional pressing cloth piece in the prior art of this patent case, this pressing cloth piece comprises a pushing body and is arranged at two presser feets of this pushing body, and the guiding channel of cloth is sent in formation one between this two presser feet, and be equiped with a part that compresses that is used to suppress cloth respectively, in addition, this two presser feets correspondence is provided with fixedly cutter and the movable cutter in order to the cutting cloth, and is provided with a following guiding device of guiding cloth in this guiding channel; During two blocks of clothes of piece, at first, the ora terminalis of two blocks of clothes is bent and inserts in the guiding channel of this presser feet spare, make cloth in this guiding channel, produce displacement along with the running of Sewing machines, and see through this fixedly cutter with this movable cutter the section that cloth bends is cut into suitable length, and utilize this time guiding device guiding cloth and this two cloth is coincided, last, sew up the zone that cloth coincides and finish sewing operation with suture needle again.

And disclosed pressing cloth piece in the above-mentioned patent case prior art, because fixedly cutter are fixing and can not adjust with the distance of these movable cutter to pressing cloth piece below cloth, therefore, above-mentioned pressing cloth piece only limits to sew up the cloth of specific thicknesses, if sew up nonspecific thickness cloth or on, when lower layer mix feeding is different-thickness, will be shown in " Fig. 1 " zone that coincided of upper strata cloth A and lower layer mix feeding B less than the zone of suture needle sewing, the suture 41 in suture needle two outsides just can't align upper strata cloth A and lower layer mix feeding B through cutting ora terminalis later, and the suture that makes both sides is only sewed on the one cloth, so, not only influence the aesthetics of cloth, effective stitching power more can't be provided.

[summary of the invention]

Main purpose of the present utility model is to improve above-mentioned disappearance, can align upper and lower layer cloth respectively through cutting edge later so as to adjusting the distance of upper and lower cutting knife to cloth, make two outside sutures that are sutured on the cloth.

For reaching above-mentioned purpose, the utility model proposes the two compress leg structures of cutting the cloth Sewing machines of a kind of four pins, six lines, this compress pin mainly has two pressing parts and form a guiding space between this two pressing part, and this two pressing part is provided with one respectively in order to compress the part that compresses of cloth, wherein, this compress pin is in pressing part and compress and be provided with an adjustment part between the part, and pressing part is provided with one first joint portion, and adjustment part is provided with one and constitutes second joint portion of combination separation relation with this first joint portion, make the user can be according to this adjustment part of the required dismounting of fabric thickness, adjust whereby be located at this compress pin on, lower cutter is to the distance of cloth, and then makes on two outside sutures on the cloth align respectively, lower layer mix feeding is through cutting edge later.

Via as can be known above, the utility model is compared to the beneficial effect that known technology reached:

One, increases the intensity that cloth is sewed up

Two, promote the overall appearance degree
