Abstract
The invention discloses a unidirectional-stitch sewing machine which comprises a rack, a sewing machine head comprising multiple parts like a sewing needle and a needle plate, and a transmission mechanism controlling the machine head to sew. Mounting holes and cloth passing grooves are formed in the needle plate, an alcove is formed in the needle plate, an annular sewing needle hole is formed in the alcove, one side of the needle plate is connected with an arc-shaped retaining plate which is positioned beside the sewing needle hole, and the retaining plate and the needle plate are in fixedly threaded connection through an inner-hexagonal screw. The retaining plate is additionally arranged beside the sewing machine needle, so that when the sewing machine starts to sew, only one sewing thread is needed to perform sewing with an annular stitch, huge convenience is brought to threading, the sewn stitch is attractive in appearance, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of Sewing machines, relate in particular to a kind of Sewing machines of unidirectional stitching.
Background technology
Sewing machines generally all is comprised of head, support, transmission and annex four parts, and wherein needle plate belongs to the accessory in the Sewing machines.Usually, Sewing machines is installed on the horizontal platen, and its head is equipped with vertical shank, and the lower parts of needle chain is connected to the eedle near working plate, the parts such as rotating shuttle of control bottom line are over against lower parts of needle, be arranged under the platen, needle plate has circular pin hole and square work feed alveolus on the platen between eedle and the rotating shuttle, the eedle of motion by under pin hole and the platen rotating shuttle cooperate sewing, feed dog under the platen passes dead slot, exposes the needle plate plane, realizes carrying the function of sewing on the needle plate.Existing Sewing machines according to the structure of needle plate, is generally all made by two-way stitching when making the stitching of annular, make process need and use two sewing threads, but such structure, the threading during stitching is inconvenient, and the stitching outward appearance of sewing up out is not attractive in appearance.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of threading convenient, and sewed up stitching unidirectional chain stitch sewing machine attractive in appearance out.
Technical solution of the present invention is achieved in that a kind of unidirectional chain stitch sewing machine, comprises frame, includes head of sewing machine and the control head transmission mechanism of sewing of a plurality of parts of suture needle and needle plate; Described needle plate is provided with installing hole and walks the cloth groove, also has concave station on the described needle plate; Have annular sewing needle hole on the described concave station; A side is connected with baffle plate on the described needle plate; Described baffle plate is positioned at by the sewing needle hole.
Preferably, described baffle plate is circular arc.
Preferably, between described baffle plate and the needle plate for by being threaded that screw is fixedly linked.
Preferably, described screw is soket head cap screw.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The present invention program's a kind of unidirectional chain stitch sewing machine, by having additional a baffle plate on the Sewing needles next door, when Sewing machines begins to sew up, only need to can carry out the stitching of loop stitch with a sewing thread, threading gets up very convenient like this, and stitching stitching appearance looks elegant out, improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of unidirectional chain stitch sewing machine of the present invention;
Accompanying drawing 2 is the partial enlarged drawing of A;
Accompanying drawing 3 is the structural representation of needle plate;
Accompanying drawing 4 is the structural representation of another angle of needle plate;
Wherein: 1, frame, 2, head of sewing machine; 3, suture needle; 4, needle plate; 5, installing hole; 6, walk the cloth groove; 7, concave station; 8, sewing needle hole; 9, baffle plate; 10, soket head cap screw.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of unidirectional chain stitch sewing machine of the present invention such as accompanying drawing 1,2, comprise frame 1, include head of sewing machine 2 and the control head transmission mechanism (not shown) of sewing of a plurality of parts of suture needle 3 and needle plate 4, described needle plate 4 is provided with installing hole 5 and walks cloth groove 6, also have concave station 7 on the described needle plate 4, have annular sewing needle hole 8 on the described concave station 7; A side is connected with baffle plate 9 on the described needle plate 4; It is other that described baffle plate 9 is positioned at sewing needle hole 8; Described baffle plate 9 is circular arc; Between described baffle plate 9 and the needle plate 4 for by being threaded that screw is fixedly linked; Described screw is soket head cap screw 10.
Sewing machine needle of the present invention, only need to carry out unidirectional stitching circulation and can carry out the stitching of loop stitch, when beginning to sew up, Sewing needles begins to sew up, because the existence of baffle plate, as long as a sewing thread just can form loop stitch, threading gets up very conveniently like this, and sews up out stitching appearance looks elegant, has improved production efficiency, and reduced cost, be applicable to large-scale batch production.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
