Abstract
The invention discloses a needle plate of a sewing machine. The needle plate comprises a needle plate body provided with mounting holes and cloth feeding slots. A groove is formed in the needle plate body and provided with a circular sewing needle hole. A stop plate which is circular-arc shaped is connected to one side of the needle plate body, is located beside the sewing needle hole, and is in fixedly threaded connection with the needle plate body through screws. The screws are internal hexagonal screws. By the aid of the stop plate added beside the sewing needle hole, only one thread is needed for sewing during working of the sewing machine, circular stitch track can be formed by the single thread at the beginning of sewing, and usage of threads for circular stitches is low, so that production cost is reduced. The needle plate is suitable for application in large scale.
Description
Technical field
The present invention relates to a kind of needle plate, relate in particular to a kind of needle plate for Sewing machines.
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 is when making the stitching of annular, because the structure of needle plate is generally all made by two-way stitching, make process need and use two sewing threads, large with line amount during stitching improved production cost, is not suitable for large-scale mass production.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of energy just can form loop stitch by unidirectional stitching sewing machine needle board.
Technical solution of the present invention is achieved in that a kind of sewing machine needle board, comprises the needle plate body, and described needle plate body is provided with installing hole and walks the cloth groove, also has concave station on the described needle plate body, has annular sewing needle hole on the described concave station; A side is connected with baffle plate on the described needle plate body; 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 body 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:
A kind of sewing machine needle board of the present invention program, by having additional a baffle plate on the Sewing needles next door, when Sewing machines is worked, only need a sewing thread to sew up, when beginning to sew up, because the existence of baffle plate, can just can form loop stitch by single line, the toroid that sews like this is low with the line amount, has reduced production cost, is applicable to large-scale in batches application.
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 sewing machine needle board of the present invention;
Accompanying drawing 2 is the structural representation of another angle of sewing machine needle board of the present invention;
Wherein: 1, needle plate body; 2, installing hole; 3, walk the cloth groove; 4, concave station; 5, sewing needle hole; 6, baffle plate; 7, soket head cap screw.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of sewing machine needle board of the present invention such as accompanying drawing 1,2, comprise needle plate body 1, described needle plate body 1 is provided with installing hole 2 and walks cloth groove 3, also has concave station 4 on the described needle plate body 1, has annular sewing needle hole 5 on the described concave station 4; A side is connected with baffle plate 6 on the described needle plate body 1; It is other that described baffle plate 6 is positioned at sewing needle hole 5; Described baffle plate 6 is circular arc; Between described baffle plate 6 and the needle plate body 1 for by being threaded that screw is fixedly linked; Described screw is soket head cap screw 6.
Sewing machine needle of the present invention, by having additional a baffle plate on the Sewing needles next door, when Sewing machines is worked, only need a sewing thread to sew up, when beginning to sew up, because the existence of baffle plate, when sewing thread is being sewed up, can just can form loop stitch by single line, the toroid that sews like this is low with the line amount, reduce production cost, be applicable to large-scale in batches application.
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.
