Referring to accompanying drawing 2, the basic structure of the sewing machine head of the band sewing mantle of the embodiment of the present application offer is the figure shows,
Also the use state of the sewing machine head with sewing mantle, head body therein 1, shank 2, syringe needle 201, presser bar are illustrated
3rd, the structure of pad body 4 and pressure foot 5 is one kind of existing sewing machine, and the planform in the application is not limited to this.This Shen
Please embodiment provide band sewing mantle sewing machine head also include sewing mantle 6, sewing mantle 6 be hollow U-shape structure, join
See that accompanying drawing 3-5, accompanying drawing 3-5 show the concrete structure of mantle 6 of sewing in the application, in its U-shape structure, include mantle the successively
One sidepiece 601, mantle end 609 and the second sidepiece of mantle 602, mantle end 609 is round and smooth to connect the first sidepiece of mantle 601 and machine
Cover the second sidepiece 602.Sewing mantle 6 is formed in one structure, the material with some strength and hardness using copper, rustless steel etc.
Material is made.For the safety in utilization of mantle 6 of sewing, the outward flange of mantle 6 of sewing is circle obtuse.More specifically, machine
The thickness of set 609 bottom of end is more than the thickness at the top of mantle end 609, and 609 bottom of mantle end has certain radian, such as
Shown in accompanying drawing 5.
One end of the first sidepiece of mantle 601 arranges the first hanger 603, and one end of the second sidepiece of mantle 602 arranges second and hangs
Ear 604, the first hanger 603 and the second hanger 604 are oppositely arranged, and the first hanger 603 and the second hanger 604 are parallel to each other, the
The diameter of the distance between one hanger 603 and the second hanger 604 more than or equal to presser bar 3.First hanger 603 and the second hanger
604 are fixed using installation for mantle 6 of sewing.Mantle 6 of sewing in the application passes through first hanger 603 and the second hanger
604 are fixedly connected presser bar 3, realize that the installation of sewing mantle 6 is fixed, while the setting of the first hanger 603 and the second hanger 604
The installation of convenient sewing mantle 6 is fixed.
The lower surface of sewing mantle 6 is concordant with the upper surface of pressure foot 5, that is, lower surface and the pressure foot 5 of mantle 6 of sewing
Upper surface matches, and the sewing machine of mantle end 609 and 602 coupling part of the first sidepiece of mantle 601 and the second sidepiece of mantle
The profile for covering 6 bottoms is identical with pressure foot 5, and sewing mantle 6 and the pressure foot 5 of this part are mutually matched identical.So can be conveniently
The use of sewing machine head, it is ensured that reduce the size of sewing mantle 6 while sewing 6 use demand of mantle as far as possible.
Also include loophole 605 on the first sidepiece of mantle 601, the effect of loophole 605 is printing opacity, and light is by loophole
Inside 605 U-shape structures for entering sewing mantle 6, loophole 605 facilitates the through wires hole threading of syringe needle 201.Loophole 605 is located at
Position of the first sidepiece of mantle 601 just to shank 2.The size shape of loophole 605 arbitrarily can be selected.Optionally, loophole 605
Optional square loophole, preferred rectangle, the ratio of the length and width of rectangle loophole 605 is 5:2, such as rectangle is saturating
When the length of unthreaded hole 605 is 1cm, the width of rectangle loophole 605 is 0.4cm, and by that analogy, actual size can be according to sewing
6 size of mantle and using need selected.

Be conducive to passing through for sewing thread.Linear slit 606 is set at the top of string holes 607, linear slit 606 is opening on the second sidepiece of mantle 602
Mouthful, facilitate sewing thread wire inlet/outlet hole 607.String holes 607 is located at the position just to shank 2 of the second sidepiece of mantle 602.String holes 607
Size shape arbitrarily can select.Optionally, string holes 607 is triangle string holes, and the base of string holes 607 is hung down with the axis of shank 2
Directly, the diameter parallel of the axis of linear slit 606 and shank 2.607 base of triangle string holes is equal with height.
For the geometric center place straight line and pin of the use of convenient sewing mantle 6, loophole 605 and string holes 607
The axes intersect of bar 2, after syringe needle 201 is elevated, during 201 through wires hole threading of syringe needle the geometric center of loophole 605,
The geometric center of the geometric center and through wires hole of string holes 607 is located on the same line.607 phase interworking of loophole 605 and string holes
Close, there is provided enough spaces carry out threading operation, and the effect with optically focused, facilitate the threading of 201 through wires hole of syringe needle.It is preferred that
, the base position height of loophole 605 is higher than the base position height of string holes 607, difference in height generally 607 base of string holes
Half, such as when the base of string holes 607 is 0.4cm, difference in height is 0.2cm.
The band that the embodiment of the present application is provided is sewed the sewing machine head of mantle, except also setting up with traditional sewing machine head function
Sewing mantle 6, sewing mantle 6 have the first sidepiece of mantle 601, mantle end 609, mantle the second sidepiece 602, the first hanger
603rd, the structure of the second hanger 604, loophole 605, linear slit 606 and string holes 607.Sewing mantle 6 is fixedly mounted on presser bar 3
On, during may be implemented in the fibrous materials such as sewing machine sewing yarn, hair, Cotton Gossypii or staple fibre, automatically by silk, hair, Cotton Gossypii or
The fibrous materials such as staple fibre separate, and prevent the fibrous materials such as silk, hair, Cotton Gossypii or staple fibre from touching 201 upper end of syringe needle
Sewing thread and enter in through wires hole, cause sewing broken string.And in sewing machine sewing process, silk, hair, Cotton Gossypii or artificial fibre
The fibrous materials such as dimension sewing mantle 6 relatively is advanced and is run, and the automatic of mantle 6 of sewing separates the fibres such as silk, hair, Cotton Gossypii or staple fibre
