Under the effect of type can be generated and the purpose that can reach, should all still fall in the revealed technology contents of the utility model can cover
In the range of.Meanwhile cited such as "upper" in this specification, "lower", "left", "right", " centre " and " one " term, also
Only it is illustrated convenient for narration, rather than to limit the enforceable range of the utility model, relativeness is altered or modified,
It is changed under technology contents without essence, when being also considered as the enforceable scope of the utility model.
The application provides a kind of sewing machine, which is preferably overedger；As depicted in figs. 1 and 2, in the sewing machine
Trimming control mechanism is installed, trimming action is executed for controlling the thread cutting mechanism in sewing machine, to realize the trimming of short-term head
Effect.In general, the thread cutting mechanism in sewing machine include moving knife, can to the moving knife moved close to or far from 4 direction of stationary knife,
And the trimming driving source of driving moving knife movement, after moving knife is moved to close 4 direction of stationary knife, moving knife blade and stationary knife on moving knife
Stationary knife blade occlusion on 4, and then suture is cut, realize automatic shearing；The moving knife and stationary knife 4 constitute cutting in sewing machine
Line knife, the stationary knife 4 are fixed on the casing in sewing machine.For convenient for narration, the cloth-feeding direction of cloth feeding mechanism in sewing machine is determined
Justice is front direction, and therefore, in sewing process, the cloth feeding mechanism driving sewing in sewing machine is moved forward.
As depicted in figs. 1 and 2, this application involves trimming control mechanism include needle plate 1 and for incuding sewing edge
Inductor 2；The needle plate 1 is fixed on the seam deck plate 7 in sewing machine, and the inductor 2 and needle plate 1 are relatively fixed, therefore feels
Answer device 2 that can be directly fixed on other components in seam deck plate 7 or needle plate 1 or sewing machine；There is appearance machine on the needle plate 1
Needle 3 down through needle falling point 101.The eedle 3 is fixedly mounted on the lower end of needle bar in sewing machine component 5 by needle holder 6,
Shank component 5 can pump, and then eedle 3 is driven to pump together.Particularly, the work feed along sewing machine
The cloth-feeding direction of mechanism work feed forward, i.e., in the longitudinal direction, the inductor 2 is located at front side, the Yi Jiding of needle falling point 101
The rear side of knife 4, and the distance between inductor 2 and needle falling point 101 X are 8-19mm；Therefore, along sewing machine cloth feeding mechanism to
The cloth-feeding direction of preceding work feed, the stationary knife 4, inductor 2 and needle falling point 101 are successively arranged from front to back.In addition, the trimming control
Mechanism processed further includes the electronic control module in sewing machine, prestores in the electronic control module and cuts time S, the inductor 2 and is cut
Line driving source is all connected with electronic control module.Infrared sensor or photoelectric sensor can be selected in the inductor 2.
This application involves trimming control mechanism can be only used for seam when the control of preceding trimming or at the end of being only used for sewing
Rear trimming control or be used for simultaneously stitch when preceding trimming control and sew at the end of rear trimming control.Trimming controls machine
Structure has been used for the principle of preceding trimming control when stitching are as follows: when sewing starts, the leading edge of sewing is formed with front pigtail, before sewing
Edge successively passes through needle falling point 101, inductor 2 and thread trimmer；Before electronic control module has sewing according to the judgement of the signal of inductor 2
When edge is by inductor 2, then it is dynamic to start control trimming driving source after cutting time S described in timing and timing completely for electronic control module
Make, and then moving knife blade and stationary knife blade is promoted to be engaged, cut front pigtail, trimming before completing.Trimming control mechanism is for stitching
The principle of rear trimming control at the end of threading are as follows: after sewing, the back edge of sewing is formed with rear line pigtail, the back edge of sewing
Successively pass through needle falling point 101, inductor 2 and thread trimmer；When electronic control module has sewing back edge according to the judgement of the signal of inductor 2
When by inductor 2, then electronic control module starts timing and the full control trimming driving source movement after cutting time S of timing,
Moving knife blade and stationary knife blade is promoted to be engaged, cut rear line pigtail in turn, after the completion trimming.
As shown in the above: trimming control mechanism mainly passes through the induction seam of inductor 2 for the method for trimming control
The reaction time T at material edge provides signal, and it is dynamic that the signal that electronic control module receives inductor 2 passes through control trimming driving source later
The time of work is cut to control moving knife, and the reaction time T of inductor 2 and to cut time S be typically all steady state value, induction
The reaction time T of device 2 is most 12ms fastly, therefore the position that sewing crosses inductor 2 will affect the accuracy that electronic control module calculates, namely
The installation site of inductor 2 directly affects the accuracy of electronic control module calculating.It is ginseng with needle falling point 101 on needle plate 1 in the application
The installation site that inductor 2 is limited according to limiting, makes the distance between inductor 2 and needle falling point 101 X 8-19mm, to make
Needle falling point 101 that the installation site of inductor 2 is slightly away from eedle 3 in the longitudinal direction and be closer to thread trimmer, thus
The line pigtail on 1 tongue of needle plate can be made steadily to go out, the accuracy that electronic control module calculates is improved, can effectively control and sew out
Remain in the length of the end of a thread on sewing after the line pigtail length and trimming come, so that stub is stable and is able to achieve short-term
The trimming effect of head, and then the second pruning of the end of a thread is saved, it saves labour turnover, improves sewing efficiency and seam quality.
Further, table 1 is that inductor 2 remains in after distance X and trimming in the longitudinal direction between needle falling point 101
Relationship between the length L of the end of a thread on sewing, as known from Table 1: between inductor 2 and needle falling point 101 in the longitudinal direction
The preferred scope of distance X is 17-19mm, and the length L that the end of a thread on sewing is remained within the scope of this, after trimming is more steady
Fixed, the range of L is 2-8mm, can steadily realize the trimming effect of short-term head.
Table 1
In above-mentioned table 1, inductor 2 remains in sewing after distance X and trimming in the longitudinal direction between needle falling point 101
On the unit of length L of the end of a thread be all mm.
So the utility model effectively overcomes various shortcoming in the prior art and has high industrial utilization value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
