Description
Technical field
The present invention relates to stitching process field, in particular to a kind of sewing machine and its line pigtail conveying device.
Background technique
Overedger can generate ceases to be busy pigtail in the rear and front end of cloth in sewing process, be known as front in cloth front end
Pigtail is known as rear line pigtail in cloth rear end.
Automatic trimming overedger can cut front pigtail and rear line pigtail in sewing process by cutting facility, thus
The process that worker carries out trimming manually is eliminated, sewing efficiency is greatly improved.
In sewing, the cloth forward conveying lasting by feed dog, but the line pigtail of cloth front end can only lean on subsequent cloth
It pushes forward.Line pigtail itself is softer, and the speed of line pigtail forward can be lower than when by the frictional force for stitching platform or other resistances
The speed of cloth forward, front pigtail are more than that when overedger carries out automatic preceding trimming, thread trimmer is cut less than front by subsequent cloth
Pigtail, or the front pigtail cut are long.
Therefore, how a kind of line pigtail conveying device is provided, is those skilled in the art's mesh in order to be sheared to line pigtail
The preceding technical issues that need to address.

Figure.
A kind of line pigtail conveying device provided by the embodiment of the present invention, comprising: air pump 1 and air ducting, air pump 1 and wind-guiding
For providing compressed air to air ducting, air pump 1 is used to blow by air ducting to the conveying direction of sewing for device connection,
So that the length direction of the line pigtail on sewing is consistent with the conveying direction of sewing.Since the material of line pigtail is more soft, wind-guiding dress
The ceases to be busy pigtail that feed dog 6 is left in the alignment of venthole 8 set blows toward cloth motion simulation direction and line pigtail can be forced with identical as sewing
Speed travel forward, to guarantee that line pigtail will not be bent, curl or be crushed below sewing, zero without other additional complexities
The positive operation of reason of line pigtail can be realized in component, when line pigtail is blown to it is consistent in the conveying direction of sewing when, convenient for thread trimmer 3 carry out
Thread chain trimming operation, therefore working efficiency is higher, furthermore equipment cost is lower, and structure is simply convenient for safeguarding.
It should be noted that main its of air ducting guides the effect of airflow direction, its related specific structure the present embodiment
It is not specifically limited, as long as can guarantee that the airflow direction by the compressed air that air pump 1 provides is guided to the conveying side with sewing
To consistent, or be slightly slanted can also, do not require that the length extending direction of line pigtail and the complete phase of conveying direction of sewing
Together.
Specifically, air ducting is to be arranged on the presser feet 5 or shield line baffle 11 of sewing machine, presser feet 5 or shield line baffle 11
It is equipped with air inlet 7 and venthole 8, air pump 1 is connect by tracheae 9 with air inlet 7, the outgassing direction of venthole 8 and sewing
Conveying direction is consistent.Sewing is placed between presser feet 5 and feed dog 6, passes through the extruding of presser feet 5 and the round-trip fortune of feed dog 6
Dynamic, sewing can travel forward, and blown by air pump 1 into air inlet 7, line pigtail can be blown to the conveying direction one with sewing
It causes.
Further, for the ease of setting air inlet 7 and venthole 8, presser feet 5 is equipped with cushion block 2, air inlet 7 and outlet
Hole 8 is arranged on cushion block 2
Specifically, cushion block 2 is equipped with the mounting hole for being mounted on presser feet 5 and prevents cushion block 2 from rotating around mounting hole
Limiting section.Wherein protrusion can be set in 2 bottom of cushion block, so that the side of the protrusion and the side of presser feet 5 contact with each other, in addition tie
The fixation for closing mounting hole can guarantee that cushion block 2 is in metastable position, and the outlet side of venthole 8 can be prevented by limiting section
To deflecting, and lose the effect for blowing line pigtail.Furthermore the installation of cushion block 2 can also be realized by other fixed forms, only
Guarantee that cushion block 2 will not deflect in its natural state.
For the ease of the connection of air pump 1 and cushion block 2, air inlet 7 protrudes from the top of cushion block 2.
Other than carrying out wind-guiding above by cushion block 2, sewing machine can also be arranged in the venthole of air ducting
On needle plate 11 or trimming knife assembly 10, the venthole of air ducting and the conveying direction of sewing are consistent, and in addition venthole can be
It is multiple.Such as when venthole is arranged 10 on needle plate 11 or trimming knife assembly, venthole at this time is located under line pigtail and sewing
The direction of motion of side, venthole alignment line pigtail toward sewing is blown, and line pigtail can be made to be held up slightly, reduces the contact with platform is stitched, into
One step reduces line pigtail and stitches the friction of platform, therefore can more smoothly travel forward convenient for line pigtail.
In order to adapt to more sewings and different sewing technologies, line pigtail conveying device provided in this embodiment further includes behaviour
Make panel and automatically controlled port 4, operation panel blows always when being equipped with sewing, preceding trimming when blow, rear trimming when blow and preceding
It blows when trimming afterwards and the selecting unit of intermittent aeration, automatically controlled port 4 is used for the mode control according to selected selecting unit
Air pump 1 processed works.
When selecting blow mode always, by automatically controlled port 4 control air pump 1 before execution trimming, in sewing, after executing
It works always when trimming；
Before selecting when trimming blow mode, air pump 1 is controlled by automatically controlled port 4 and is worked when trimming before execution, is sewed
In and execute after trimming when air pump 1 do not work；
When the equal blow mode of selection front and back trimming, air pump 1 is controlled in the preceding trimming of execution, rear trimming by automatically controlled port 4
When work, air pump 1 does not work in sewing；
After selection when trimming blow mode, by automatically controlled port 4 control air pump 1 after execution trimming when work, execute
Air pump 1 does not work in preceding trimming, sewing；
When selecting intermittent aeration mode, air pump 1 is controlled by automatically controlled port 4 and is worked in the preceding trimming of execution, rear trimming,
Time air pump 1 as defined in being spaced in sewing works.
One embodiment of the present of invention additionally provides a kind of sewing machine, conveys including line pigtail described in any of the above-described embodiment
Device.Its advantages refer to above-described embodiment, and details are not described herein again.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
A kind of sewing machine provided by the present invention and its line pigtail conveying device are described in detail above.It answers herein
With a specific example illustrates the principle and implementation of the invention, the explanation of above example is only intended to help to manage
Solve method and its core concept of the invention.It should be pointed out that for those skilled in the art, not departing from
, can be with several improvements and modifications are made to the present invention under the premise of the principle of the invention, these improvement and modification also fall into this hair
In bright scope of protection of the claims.
