Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of the present invention is to provide a kind of sewing machines, existing for solving
Have and easily occurs sewing stitching irregular problem when sewing thick fabric or leather in technology.
In order to achieve the above objects and other related objects, the present invention provides a kind of sewing machine comprising needle plate, pressure foot with
And the presser bar for being connected with pressure foot and pressure foot being driven to go up and down, sewing is pressed on needle plate by pressure foot when declining, in pressure foot
Or needle plate is equipped with the venthole for blowing to sewing, the venthole is connected by tracheae with gas source.
Preferably, the venthole is located on the pressure foot, and air supply channel, the air supply channel are equipped in presser bar
One end communicated with the venthole on the pressure foot, the other end of air supply channel is connected with the tracheae.
Preferably, there is the air cavity communicated with the air supply channel, the venthole is located at air cavity in the pressure foot
In cavity wall, venthole is multiple, includes that the main stomata communicated with the air cavity and the two rows symmetrical about main stomata are secondary
Stomata.
Preferably, the secondary stomata in every row is arranged along the sewing direction of travel.
Preferably, the venthole is located on the needle plate, and the oblique ejection air-flow of venthole.
As described above, sewing machine of the invention, has the advantages that outlet is arranged on pressure foot or needle plate in use
Hole is blown using to sewing, is reduced the relative friction forces between sewing and needle plate or pressure foot, is passed through sewing with stable speed
At pressure foot, the stability for causing sewing to convey because of relative friction forces is avoided, so as to improve the sewing effect of sewing.

Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
Fig. 1 is please referred to Fig. 2.It should be clear that structure, ratio, size etc. depicted in this specification institute attached drawing, only to
Cooperate the revealed content of specification, so that those skilled in the art understands and reads, being not intended to limit the invention can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influencing the effect of present invention can be generated and the purpose that can reach, it should all still fall in disclosed skill
In the range of art content can cover.Meanwhile in this specification it is cited as "upper", "lower", "left", "right", " centre " and
The term of " one " etc. is merely convenient to being illustrated for narration, rather than to limit the scope of the invention, relativeness
It is altered or modified, under the content of no substantial changes in technology, when being also considered as the enforceable scope of the present invention.
The present invention provides a kind of sewing machine comprising head and place conveying cloth platen etc., sewing machine it is basic
Structure is not described in detail here, and relates only to the specific structure of eedle sewing place, including needle plate (being unillustrated), pressure foot 2 and
Sewing is pressed in needle plate when pressure foot 2 declines as shown in Figure 1 by the presser bar 1 for being connected with pressure foot 2 and pressure foot being driven to go up and down
On, the venthole for blowing to sewing is equipped on pressure foot 2 or needle plate, the venthole is connected by tracheae 3 with gas source.
In sewing, sewing is pressed on needle plate by pressure foot 2, and sewing and pressure foot 2 and needle plate generate relative friction, especially thicker
Fabric or leather fabric, the relative friction forces are larger, seriously affect the kinetic stability of sewing, keep institute's suture mark unstable
Fixed, the present invention reduces the relative friction that sewing is subject to during exercise with this by blowing at pressure foot 2 or needle plate to sewing,
Its kinetic stability is improved, also just makes institute's suture mark uniform and stable, improves sewing effect.
As shown in Figure 1, venthole is located on the pressure foot 2 in the present embodiment, and air supply channel is equipped in presser bar 1
(not shown), one end of the air supply channel are communicated with the venthole on the pressure foot 2, the other end of air supply channel with it is described
Tracheae 3 is connected.The presser bar 1 of the present embodiment is hollow, forms above-mentioned air supply channel, and connection tracheae 3, which is realized, blows.
Preferably to blow to sewing, as shown in Figure 2, have and the air supply channel phase in pressure foot 2 in the present embodiment
Logical air cavity, the venthole are located in the cavity wall of air cavity, and venthole is multiple, includes the main stomata 5 communicated with the air cavity
And the two rows secondary stomata 4 symmetrical about main stomata 5.Venthole is arranged in the main body of pressure foot 2 in the present embodiment,
It is not disposed on two presser feets to refer to, come into full contact with primarily directed to sewing and pressure foot main body, relative friction forces are larger at this；But
Do not negate that may also set up venthole on presser feet refers to, can select to be arranged as needed.The present embodiment passes through main stomata 5 and secondary gas
The cooperation in hole 4 can adjust gas flow, make to form air gap between sewing and pressure foot, reduces relative friction, makes to sew more stable.
Preferably, the secondary stomata 4 in every row is arranged along the sewing direction of travel, can form the gas for pushing sewing to advance
Stream is beneficial to sewing traveling with this when reducing the frictional force of sewing and pressure foot.
To make sewing stablize conveying, improving sewing effect, above-mentioned venthole is located on the needle plate in the present embodiment, does not give
Diagram, and the oblique ejection air-flow of venthole.Venthole is arranged in the present embodiment on needle plate, can blow to sewing, keeps sewing outstanding
It is floating, reduce the relative friction forces between needle plate and sewing.Pressure foot is affixed to avoid gas from flowing through ambassador's sewing, and the present embodiment is by outlet
The outlet-inclined impeller vane in hole is arranged, and sprays air-flow inclination, give sewing it is certain lift power, so as to improve sewing stability.Needle plate
Upper venthole can directly be connected with above-mentioned tracheae.
In conclusion sewing machine of the invention reduces sewing with this and exists by blowing at pressure foot or needle plate to sewing
The relative friction being subject in movement improves its kinetic stability, also just makes institute's suture mark uniform and stable, improves sewing effect.Institute
With the present invention effectively overcomes various shortcoming in the prior art and has high industrial utilization value.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
