Description
Technical field
The present invention relates to the template sewing in clothes process equipment field, more particularly to a kind of thread tension adjust automatically
Machine.
Background technology
Template sewing machine is to be placed on sewing machine according to each position technological design sewing template of clothes, then by sewing template
On, according to technological standards it is automatic, be efficiently completed sewing, widely applied in garment production instantly.By using seam
Thread template, then coordinate the reasonable layout of streamline, clothes factory can reduce the dependence to skilled worker, solve technical bottleneck, carry
High sewing efficiency, it is ensured that the quality of sewed product is unified, and positive power-assisted is provided for mass, standardized work.
The sewing machine of industrial sewing is generally used at present, during for each suture, can more be smoothed out, it will usually in sewing
Tension adjusting device is set in frame, to adjust the suture tension or the relaxation degree that pass in suture needle.But this mode is being answered
Inconvenience regulation will be set because of thread tension adjusting apparatus by using, in sewing operation progress, when operator has found, wherein having
When the tightness of some sutures excessively relaxes or need to tightly adjusted very much, it is necessary to be adjusted manually, thus it is extremely inconvenient.Furthermore,
Due to that cannot adjust in time, defect ware is often produced, for unattended template sewing machine, often etc.
To when finding, greater loss is had resulted in, causes sewing operation not to be automatically performed.Calculate to pre-set by simple program
The scheme of good tension value can not make adjustment according to actual condition situation, not reach the effect of intelligent regulation.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of mould of thread tension adjust automatically
Plate sewing machine.
The present invention is achieved by the following technical solutions：A kind of template sewing machine of thread tension adjust automatically, including

As further improvement of these options, in addition to blanking disc and shielding gasket, shielding gasket has two, and its is tight
Set by head of sewing machine, blanking disc is arranged between two shielding gaskets, blanking disc is made by metal material, shielding gasket by
Elastomeric material makes.
As further improvement of these options, thread tension sensor is from tension sensor of assuming a posture.
The present invention has advantages below compared with prior art：The control unit connection of magnet coil and template sewing machine, this
Sample reads current Trace speed by control unit, the scope that budget tension force should be controlled, then electric in magnet coil by controlling
The size of stream is automatically controlled to realize to tension force, and the intelligent Process of template sewing machine can be promoted by such scheme,
Automated condtrol is further realized, human cost is reduced；The clamping structure being engaged by using magnet coil and armature, it is convenient
, in actual use, can be by default program in systems in magnet coil for the adjustment of the thrust of cable-clamping disc
The current strength flowed through is adjusted, and realizes the effect for automatically adjusting thread tension；To prevent the regulation of magnet coil excessively fierce
Broken string or other situations are caused, the strength of adjustment of magnet coil can effectively be absorbed by installing buffer spring, and be slowly released
Come, set by such, buffer spring is played a part of not being the offer thrust in traditional structure, but absorb and push away
Power, is slowly released again after storage, is played a part of buffering regulation power, it is ensured that the stability of sewing operation, is reduced burst
The probability that event occurs；The magnetic force for being provided for the generation of segment magnet coil of blanking disc is for head of sewing machine inner body
Influence.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is electromagnetism tensioning device structural representation.
Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementations
Example.
As depicted in figs. 1 and 2, a kind of template sewing machine with electromagnetism tensioning device, including station platform 1, head
7th, clamping plate device 6, cannelure 5, motion crossbeam 3 and sliding shoe 2, head 7 are arranged on station platform 1, and clamping plate device 6 is arranged at slip
On block 2, sliding shoe 2 can horizontally slip along crossbeam 3 is moved, and motion crossbeam 3 can be along cannelure 51 on station platform
Move forward and backward, it is characterised in that：Electromagnetism tensioning device 8 and thread tension sensor 4, electromagnetism are provided with head 7
Force regulator 8 includes cable-clamping disc 81 and installs screw rod 82, in addition to magnet coil 83 and armature 84, magnet coil 83 and armature 84
The both sides of cable-clamping disc 81 are respectively arranged at, screw rod 82 is installed and is fixed on head 7 through magnet coil 83, armature 84 and cable-clamping disc 81
On, thread tension sensor 4 and magnet coil 83 are connected with the control unit of template sewing machine.By using magnet coil 83
The clamping structure being engaged with armature 84, the adjustment of the convenient thrust for cable-clamping disc 81, in actual use, can by
Default program is adjusted to the current strength flowed through in magnet coil 83 in system, and realization automatically adjusts thread tension
Effect.Current Trace speed is so read by control unit, the scope that budget tension force should be controlled, then by controlling electromagnetic wire
The size of electric current is automatically controlled to realize to tension force in circle 83, and the intelligence of template sewing machine can be promoted by such scheme
Change process；Suture quality is unstable or other factors under the influence of, can sometimes occur thread tension increase suddenly or rapid drawdown feelings
Condition, now only can not just realize the judgement for real Tensity size by electromagnetism tensioning device to adjust, and be stitched by setting
Thread tension sensor 4 can measure thread tension size in real time, pass through the big of real time contrast's anticipation tension value and real tension value
It is small to adjust the size of current of magnet coil 83 in time, so as to realize the intelligent automatic control for thread tension, realize intelligence
Can automation adjustment.
Armature 84 is set close to the side of head of sewing machine 7, and magnet coil 83 is arranged at the side away from head of sewing machine 7.
Magnet coil 83 away from head of sewing machine 7, can so reduce the magnetic force of the generation of magnet coil 83 for head of sewing machine 7 inside
Part influence, it is ensured that the sewing quality and job stability of sewing machine.
Also include buffer spring 85, buffer spring 85 is installed against the side of cable-clamping disc 81, positioned at cable-clamping disc 81 and electromagnetic wire
Between circle 83.To prevent the regulation of magnet coil 83 from fiercely causing broken string or other situations excessively, installing buffer spring 85 can
The strength of adjustment of magnet coil 83 is effectively absorbed, and is slowly released, is set by such, what buffer spring 85 was played
Effect is not the offer thrust in traditional structure, but absorbs thrust, is slowly released again after storage, plays buffering regulation
The effect of power, it is ensured that the stability of sewing operation, reduces the probability that accident occurs.
