Abstract
The invention relates to a straightening-type sewing machine presser foot which comprises a supporting member and a pressing member. The supporting member is connected with the pressing member through a spring rotating device. The pressing member is provided with a needle threading position. The straightening-type sewing machine presser foot is characterized in that a straightening member is arranged on one side of the pressing member and comprises a bottom piece and a stop piece, one end of the bottom piece is fixedly connected with the pressing member, the other end of the bottom piece is fixedly connected with the stop piece, the stop piece protrudes out of the bottom piece downwards, and the distance between the inner side of the downward protruding portion of the stop piece and the needle threading position is the distance between the edge of a cloth to be sewn and the mark of a needle. The invention further provides a straightening sewing technology. According to the straightening member, it can be ensured that the cloth to be sewn is straight in moving direction on the premise that a sewing worker does not need to stare at the moving direction of the cloth, and the labor intensity of the sewing worker can also be reduced.
Description
?
Technical field
The present invention relates to a kind of sewing-machine foot and sewing technology, relate to specifically a kind of aligning held sewing machine presser feet and aligning sewing technology.
Background technology
Presser feet is generally all housed on Sewing machines, and presser feet is fixed on the frame support of Sewing machines, and when bearing moves up and down, presser feet carries out intermittence and moves up and down.Presser feet generally includes support portion and press section, between support portion and press section, is connected by spring rotating device, carries out intermittence while moving up and down at presser feet, and cloth is pushed down in press section, prevents that suture needle from taking up processing cloth.But existing sewing-machine foot in use, can only lean on artificial aligning, if grow the sewing of distance, sewer's operant level is had to higher requirement, the phenomenon that often can cause cabling bending to be done over again, wastes a large amount of manpowers, has reduced operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of and increase work efficiency, save the aligning held sewing machine presser feet of manpower.
Meanwhile, the present invention also provides a kind of aligning sewing technology addressing the above problem.
The technical scheme that the present invention solves above technical problem is: a kind of aligning held sewing machine presser feet, comprise supporting member and pressing member, described supporting member is connected by spring rotating device with described pressing member, the described pressing member setting position of threading a needle, it is characterized in that, one side of described pressing member arranges aligning member, described aligning member comprises egative film and catch, one end of described egative film is fixedly connected with described pressing member, the other end of described egative film is fixedly connected with described catch, described catch protrudes described egative film downwards, its inner side of protruding downwards position with described in the thread a needle distance of position be the distance of cloth to be sewed edge to needlework mark.The width of egative film is for regulating the width at cloth to be sewed edge, catch is for aligning the trend of waiting cloth to be sewed, and by aligning member, machinist does not need to stare at the trend of cloth always, what can guarantee cloth to be sewed moves towards straight, can reduce again machinist's labour intensity.
Being further defined to of technical solution of the present invention, the height that described catch protrudes is downwards 1 ~ 3mm, the height of catch can not exceed the thickness of cloth, otherwise can affect the Sewing machines hand-manipulating of needle.
Further, the edge at the downward protrusion position of described catch is arc angle, prevents that cloth from walking the askew cloth that makes to destroy, and meanwhile, the table top of protection Sewing machines is not damaged.
Further, described egative film is identical with the thickness of described pressing member, improves the intensity of aligning member, extends its service life.
Further, between described egative film and described pressing member, by being welded and fixed, make old-fashioned sewing-machine foot repacking convenient, without again preparing presser feet.
Further, described egative film and described catch are one-body molded, improve the intensity of aligning member, extend its service life.
Further, described pressing member comprises at least one position of threading a needle, and improves the adaptability of aligning member.
Another technical scheme provided by the invention is: a kind of aligning sewing technology, carries out as follows:
I, select aligning held sewing machine presser feet, the inner side at the downward protrusion position of its egative film with described in the thread a needle distance of position be the distance of cloth to be sewed edge to needlework mark;
II, cloth to be sewed edge is propped up to the downward protrusion position of egative film, sew by normal sewing steps.
The invention has the beneficial effects as follows: aligning held sewing machine presser feet provided by the invention and aligning sewing technology, by the application of aligning member, the width of egative film is for regulating the width at cloth to be sewed edge, catch is for aligning the trend of waiting cloth to be sewed, by aligning member, machinist does not need to stare at the trend of cloth always, and what can guarantee cloth to be sewed moves towards straight, can reduce again machinist's labour intensity; The present invention is simple in structure, is convenient to the transformation of old-fashioned sewing-machine foot, strong adaptability, and intensity own is high, long service life.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of aligning held sewing machine presser feet provided by the invention;
Fig. 2 is a kind of structural representation of aligning held sewing machine presser feet bottom surface provided by the invention;
Fig. 3 is the structural representation of aligning member provided by the invention.
The specific embodiment
embodiment 1
The open a kind of aligning held sewing machine presser feet of the present embodiment, as shown in Figure 1, the structural representation of its bottom surface as shown in Figure 2, comprises supporting member 1 and pressing member 2 to its structural representation, supporting member 1 is connected by spring rotating device with pressing member 2, and pressing member 2 arranges at least one position 3 of threading a needle.The ordinary construction that above-mentioned supporting member 1 and pressing member 2 are sewing-machine foot, is divided into various types of presser feets, for example infantees bar presser feet, nail catcher presser feet, presser foot for zip, common crimping presser feet etc.
In addition, the present invention also comprises that a side that is arranged at pressing member 2 is welded and fixed an aligning member 4, and the structural representation of described aligning member as shown in Figure 3, comprises egative film 5 and catch 6, and egative film 5 and catch 6 are one-body molded.One end of egative film 5 is fixedly connected with pressing member 2, and the thickness of egative film 5 is identical with the thickness of pressing member 2.The other end of egative film 5 is fixedly connected with catch 6, and catch 6 protrudes egative film 5 downwards, and its inner side of protruding position is downwards the distance of cloth to be sewed edge to needlework mark with the distance of the position 3 of threading a needle.The width of egative film is for regulating the width at cloth to be sewed edge, catch is for aligning the trend of waiting cloth to be sewed, and by aligning member, machinist does not need to stare at the trend of cloth always, what can guarantee cloth to be sewed moves towards straight, can reduce again machinist's labour intensity.
