In order to solve the above-mentioned technical problem, the technical scheme that the utility model is provided is as follows：A kind of thread cutting mechanism, is at least wrapped
It includes fixed blade and is relatively fixed the movable blades that blade is flexibly connected along its length, one end end of the fixed blade is set
There is outer blade, the extending direction of the outer blade is relatively fixed the length direction inclination of blade；The end of the movable blades is set
There is the bracing wire end with the outer blade interaction of fixed blade, the bracing wire end is equipped with bracing wire gap, is formed in the bracing wire gap
Interior blade.
A kind of preferred embodiment is equipped with guiding mechanism between the fixed blade and movable blades.
A kind of preferred embodiment, the guiding mechanism include at least two leads being set on movable blades and are set on
Fixing cutter on piece is used for the guide groove being slidably connected with lead.
A kind of preferred embodiment further includes the driving machine for the movable blades to be driven to be relatively fixed blade movement
Structure.
A kind of preferred embodiment, the driving mechanism include the Motionless electromagnetic seat and electric rotating magnetic support of electromagnetism connection, institute
It states and electromagnetism connecting rod is fixedly connected on electric rotating magnetic support, the movable blades are equipped with the connection for being connect with electromagnetism connecting rod
Column, the position that the electromagnetism connecting rod is connect with connecting pole are equipped with slot hole or arcuate socket.
A kind of preferred embodiment is additionally provided with elastic mechanism between the movable blades and fixed blade.
The thread cutting mechanism of the utility model, first movable blades are driven to bracing wire gap release position, then will sewing
Line sets back around bracing wire gap, movable blades are entered, and cuts sewing thread under the collective effect of interior blade and outer blade, has
Simple structure, convenient control and the technical advantage convenient for automation control.
Description of the drawings
Fig. 1 is the structure diagram of the present embodiment thread cutting mechanism.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
" on ", " under ", "front", "rear", " interior ", " outer " it is to be appreciated that term in the description of the present invention,
It is based on orientation shown in the drawings or position relationship to wait the orientation of instructions or position relationship, is for only for ease of and describes this practicality newly
Type must have specific orientation with the device or element for simplifying description rather than instruction or hint meaning, with specific orientation
Construction and operation, therefore it is not intended that limitation to the utility model.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected, being integrally connected or detachably connecting
It connects；It can be the connection inside two elements；It can be directly connected, can also be indirectly connected by intermediary, for this
For the those of ordinary skill in field, concrete meaning of the above-mentioned term in the utility model can be understood with concrete condition.
As shown in Figure 1, a kind of thread cutting mechanism 600 of the present embodiment, for sewing thread being cut after the completion of knotting in coiling.
The support plate 210 being wherein vertically arranged for the button supporting mechanism of coiling button to be placed to include, the support plate 210 are equipped with knob
Detain placing groove 220.The button placing groove 220 is preferably the U-lag or V-shaped groove of upper end opening.
The thread cutting mechanism 600 of the present embodiment includes fixed blade 620 and is relatively fixed the movable blades of blade flexible connection
610.Wherein fixed blade 620 is close to support plate 210（Side far from winding mechanism）Position be towards support plate outer knife
Sword 621, the extending direction of the outer blade are relatively fixed the length direction inclination of blade, preferably vertically.Movable blades 610 from
It is the bracing wire end that may pass through button placing groove 220 by holding end, which is equipped with bracing wire gap 611, in the bracing wire gap 611
Blade in formation.During trimming, 610 bracing wire end of movable blades passes through button placing groove 220, and sewing thread is bypassed bracing wire gap
611, movable blades 610 are retracted, and under the collective effect of interior blade and outer blade, sewing thread is cut.
It should be noted that in the present embodiment, for driving the driving mechanism of the movement of movable blades 610 in the prior art
Range of choice it is wider, the application does not do this sole limitation.The present embodiment only provides a kind of preferably embodiment as ginseng
