Description
Technical field
The utility model belongs to clothes manufacturing equipment technical field, is related to a kind of presser foot component of sewing machine.
Background technique
Sewing machine is formed one or more stitchings on sewing, is made one or more layers seam with one or more sewing thread
The machine that material interweaves or unites by a seam.Presser feet is the important component on sewing machine, for applying pressure on sewing surface, is maintained
Sewing is fixed, guarantees the accurate reliable of stitching sewing machine.When usual sewing machine sewing cloth, sewing stage needs are just started
There are suture the end of a thread of certain length at eedle eye, and suture will not be deviate from slave pinprick when having guaranteed seam.Eedle eye
The end of a thread of upper certain length can stay in sewing sewing initial position when playing seam and form " Bird's Nest ", influence the beauty of sewing.
Chinese patent (notification number: CN206204567U, publication date: 2017-05-31) discloses a kind of sewing machine belt secant
Knife presser feet, including presser feet handle and pressure foot, presser feet handle are hinged with pressure foot, and the front of pressure foot is equipped with central wire casing, presser feet
The middle part of plate is equipped with crossed beam trunking, and central wire casing is connected with crossed beam trunking, which is characterized in that the bottom middle of pressure foot has peace
Tankage is fixed with thread cutter in mounting groove, and the blade of thread cutter is located in crossed beam trunking, and the bottom of pressure foot is fixed with protection skin,
There is the scarce seam being correspondingly arranged with central wire casing and crossed beam trunking, protection skin is bonded the bottom surface of entire pressure foot in protection skin.
There are a gap, slit aperture is set central wire casing arc end the band knife presser feet designed in above patent document on presser feet
Blade is set, is cut off on the top presser feet gap edge of a knife of the end of a thread clamped when playing seam, is cut off the end of a thread and solve the problems, such as " Bird's Nest ".But it is this
With knife presser feet due to the crossed beam trunking for offering insert groove on presser feet and allowing to be cut off suture and pass through, thin material tatting cloth is being sewed
The case where when with knitting cloth, cloth is easy to be squeezed into crossed beam trunking, leads to blade cutting cloth.
Summary of the invention
The utility model aiming at the above problems existing in the prior art, provides a kind of presser foot component of sewing machine, this reality
With it is novel the technical problem to be solved is that: how to effectively prevent while removing Bird's Nest damage sewing.
The purpose of this utility model can be realized by the following technical scheme:
The lower end side of a kind of presser foot component of sewing machine, including presser feet handle, the presser feet handle is kept to the side equipped with presser feet, another
Side is equipped with presser feet bottom plate, and the pressing sole front edge of board has the guide part being upturned, which is characterized in that presser feet bottom plate court
The side kept to the side to the presser feet have groove and with the presser feet keep to the side between form needle falling hole；The presser feet bottom plate is before
End position has to keep to the side the backgauge portion to lean with the presser feet, and the presser feet bottom plate is installed with tangential knife close to back-end location
Piece, the cutting edge of the tangent line blade is towards having passing channel between the needle falling hole and tangent line blade and the needle falling hole.
The principle is as follows: tangent line blade is located at needle falling hole rear, and passing channel is connected with needle falling hole, so that tangent line blade
Cutting edge face needle falling hole, for sewing during sewing, presser feet keeps to the side to limit the left-right position during sewing transports, eedle eye
Suture the end of a thread that place is stayed is reached at tangent line blade by passing channel, can be by property cut.Needle falling hole front end is equipped with backgauge
Portion can flatten the sewing by needle falling hole in advance, avoid sewing during sewing from swelling at needle falling hole, be squeezed into
In line passage, and then sewing is cut bad phenomenon by tangent line blade in the feeding process.This presser foot component is by changing presser feet bottom plate
Structure realizing that can also guarantee will not when sewing thin material tatting cloth and knitting cloth while removing a Bird's Nest ball of string
There is the case where cutting damage sewing.
In the presser foot component of above-mentioned sewing machine, the lower end of the presser feet handle has U-shaped mounting groove, the pressing sole

In in the mounting groove, the mounting base one is hinged on the presser feet handle by screw, the mounting base two and the installation
It is connected between the slot bottom of slot by spring.Limiting slot is also provided in mounting base two, screw is plugged in limiting slot to mounting base
Two are limited, and mounting base two and entire presser feet keep to the side to move up and down.
In the presser foot component of above-mentioned sewing machine, the bottom surface of bottom surface and the presser feet bottom plate that the presser feet keeps to the side is
Plane.According to the difference of sewing tech, the difference of sewing height, the bottom surface that presser feet keeps to the side, which can choose, is lower than or flushes in presser feet
The bottom surface of bottom plate；If sewing lows while height, the bottom surface that presser feet keeps to the side is lower than the bottom surface of presser feet bottom plate；If cloth
It is smooth, then the bottom surface flush of bottom surface and presser feet bottom plate that presser feet keeps to the side.
In the presser foot component of above-mentioned sewing machine, insert groove is offered on the presser feet bottom plate, on the presser feet keeps to the side
Recessing groove is offered, one end of the tangent line blade is embedded in the insert groove and is fixed on the presser feet by blade pressuring plate
On bottom plate, the other end of the tangent line blade is embedded in the recessing groove；The passing channel is the side of the presser feet bottom plate
The gap between side kept to the side with the presser feet.
In the presser foot component of above-mentioned sewing machine, have between the side that the side of the guide part and the presser feet keep to the side
There are gap, junction of the backgauge portion between the guide part and the presser feet bottom plate ontology.
In the presser foot component of above-mentioned sewing machine, the tangent line blade is straight knife or V-type angle of throat, the tangent line blade
Cutting edge face described in passing channel；The backgauge portion is removably connected on the presser feet bottom plate or the presser feet bottom plate
It is integrally formed with the backgauge portion.
Compared with prior art, the presser foot component in the utility model is gone by changing the structure of presser feet bottom plate in realization
While except a Bird's Nest ball of string, it can also guarantee to be not in cutting damage sewing when sewing thin material tatting cloth and knitting cloth
The case where.
