Background technique
Flat seam machine is also flatcar, is generally commonly referred to as single needle lockstitch m/c；Flat seam machine mainly uses a sewing thread, on sewing
A kind of stitching is formed, the machine for making one or more layers sewing interweave or unite by a seam.Two kinds of purposes of thin material and thick material are generally divided into,
The products such as fabrics and leather, plastics, paper, the thin material such as flush joint function sewing cotton, fiber crops, silk, hair, staple fibre are generally used for needle
It knits, underwear, shirt, uniform etc., thickness material is generally used for all kinds of gym suits, and jean, fashionable dress, overcoat, shoes and hats, skin is young, luggage etc.,
Flat seam machine is car type most basic in sewing device, and the stitching neat appearance that sews, stitching are uniform, it is smooth securely, sewing speed
Degree is fast, easy to operate, using being easily understood.The needle gage regulating mechanism of existing flat seam machine is adjusted by adjusting stud and feeding mostly
Device is come what is realized, and reciprocal collision type contact can be occurred by adjusting when reinforcing seam between stud and feed regulator, to generate bright
Aobvious noise；Surrounding enviroment and operative employee are caused with very big influence.And the impact force for colliding generation between the two is very big, easily
Fatigue rupture occurs, seriously affects part service life.
Chinese patent (notification number: CN105734849A, publication date: 2016-07-06) discloses a kind of flush joint needle pitch tune
Save mechanism, it includes the first rocking bar, and one end of the first rocking bar is equipped with the fixed rotation axis of axis, the other end of the first rocking bar with fall
One end, the one end of connection structure for stitching connecting rod are hinged, and the other end and needle gage adjusting block of connection structure are hinged, and needle gage adjusting block exists
It moves and fixes under the control of needle gage adjustment portion, the one end for backstitching one end and swing seat far from the first rocking bar of connecting rod is hinged,
The other end of swing seat drives feed spool to be rotated about axis, and the middle part of swing seat is equipped with the fixed rotation axis in position；Connection structure
Including connecting rod, the second rocking bar, one end of connecting rod one end hinged with connecting rod is backstitched with the first rocking bar is hinged, the other end of connecting rod with
One end of second rocking bar is hinged, and the other end and needle gage adjusting block of the second rocking bar are hinged.
Structure in above patent document is excessively compact, and assembly difficulty has seriously affected production efficiency.Installation space simultaneously
The size for greatly having limited part increases the difficulty of processing of part, increases manufacturing cost.
Summary of the invention
The present invention addresses the above problems in the prior art, provides a kind of needle gage regulating mechanism of flat seam machine, this hair
It is bright the technical problem to be solved is that: it is simple, low in cost and can effectively prevent how to provide in flat seam machine a kind of assembly
Generate the needle gage regulating mechanism of noise.
Object of the invention can be realized by the following technical scheme:
A kind of needle gage regulating mechanism of flat seam machine, flat seam machine include casing and feed spool, and the needle gage regulating mechanism includes
The needle space standard plate being arranged on casing, the feeding crank for driving the feed spool to swing and the tune being connected with the needle space standard plate
Save stud, which is characterized in that the needle gage regulating mechanism further includes the first rocking bar and the second rocking bar, and the middle part of the first rocking bar is hinged

One end of head is hinged, and the other end of the connector is connect with the adjusting stud by axial screw, and the needle space standard plate is logical
Attachment screw is crossed to be fixed on adjusting stud.Connector is moved and is fixed under the control for adjusting stud.
In the needle gage regulating mechanism of above-mentioned flat seam machine, first rocking bar is in long strip-board shape, first rocking bar
One middle side part is connected with rotation axis and is connect by the rotation axis with the casing；First rocking bar is opened by the position of close end
Length direction equipped with waist-shaped hole and waist-shaped hole is consistent with the length direction of first rocking bar；The waist-shaped hole forms the cunning
Slot.
In the needle gage regulating mechanism of above-mentioned flat seam machine, second rocking bar is in long strip-board shape, second rocking bar
There are connecting hole one and connecting hole two in both ends respectively, and the slide bar is located at the side of second rocking bar and end is plugged in the company
It connects in hole one, is inserted with the connecting pin being connected with the connector in the connecting hole two.
In the needle gage regulating mechanism of above-mentioned flat seam machine, the connector, adjusts stud and needle space standard plate at axial screw
It is located on the same line.
Compared with prior art, having the advantage that in the present invention
1, the structure in the present invention is collided using the face contact type between slide bar and sliding slot, is increased between collision
Contact area reduces the pressure that contact surface is born, improves the service life of part；The power of collision rod piece is increased simultaneously
Arm lengths reduce the impact force that rod piece collision generates, suitably reduce the noise generated between collision rod piece, improve peripheral ring
Border.
2, the four-bar mechanism in existing needle gage regulating mechanism is simplified to Slide bar structure in the present invention, centre eliminates one
A connecting rod suitably relaxes limitation of the installation space to part size, reduces the difficulty of processing of part, save manufacture at
This.
3, the structure in the present invention changes the connection type between rod piece, articulated manner has been changed to slide bar form, very
Manual assembly difficulty is reduced in big degree, improves productivity effect.
