Abstract

The invention discloses a thread trimming method, a thread trimming mechanism and an embroidery machine using the thread trimming mechanism. When the embroidery machine needs thread trimming, the thread trimming method comprises the following steps of step 1, driving a thread hook to stretch out of a thread hooking mechanism to hook and pull a facial thread back to an appropriate position by a control system, wherein the appropriate position is used for ensuring enough allowance of the hooked facial thread. Compared with the prior art, the thread trimming method and related structures have the following advantages: the thread hook is driven to stretch out of the thread hooking mechanism to hook and pull the facial thread back to the appropriate position by the control system, and the pulled facial thread has enough allowance; the thread hook is then controlled to get away from the facial thread, and the facial thread can be in a loosened and unstressed state; the facial thread can be accurately cut off through a thread trimming device; finally, in order to let an embroidery needle to continue embroidery next time, the control system can be used for controlling the thread hook to pull the cut facial thread back to the thread hook, in a thread trimming process, the facial thread is in a loosened state, and a user has no need to worry about that the facial thread is ruptured and gets away from the embroidery needle. According to the thread trimming method, the problem of halting caused by thread trimming can be effectively and completely eradicated or reduced.

Description

A kind of thread cutting method, thread cutting mechanism and the embroidery machine using the mechanism
Technical field
The present invention relates to a kind of method of trimming, thread cutting mechanism and the embroidery machine using the mechanism.
Background technology
Rope embroidery machine is used to embroider to restrict to be fixed on carrier by thinner embroider line embroidery.Discontinuous flower is embroidered on carrier Type, occurs one section of transition embroider line between discontinuous flower pattern, the embroider line of the transition in flower pattern, it is necessary to embroider into later by manually leading to Special scissors is crossed to be cut off.Labor workload is larger, easily occurs that leakage is cut or mistake is cut.
In addition after the completion of a style embroidery, rope also must manually be cut, and cannot otherwise remove the good carrying of embroidery Thing, carries out embroidery next time.
A kind of existing trimming mode is a kind of head cut by scissors bit and embroider rope, and the mechanism is due to the scissors head breadth It is wealthy, it is impossible to accurately to cut embroidery rope in the effective head lower section that is arranged at.Cut embroidery rope, it is necessary to by artificial, rope will be embroidered and pulled Or hook delivers to the appropriate location in front of scissors bit, then promote scissors bit to feed and trimming action by driving structure, will could embroider Rope is cut.The trimming action of scissors bit needs independent power drive, while easily miscut is to upper thread.
Another kind is to hook hook by line to take upper thread, and the process that hook takes completes that by thread cutter or manually line is cut and will be cut Disconnected upper thread is hooked on line hook, is the drawbacks of this kind of trimming mode, and line hooks upper thread always tensioning state during hook takes, and With the persistent movement that line is hooked, the tension force of upper thread is also continually changing, the upper thread especially larger line of fragility, it is likely that in thread cutter It is just broken before not cutting;Or, it is likely that thread cutter not completely cut line before just from trimming break or Person breaks elsewhere, and under tension, upper thread can surprisingly come off from embroidering pin, so as to need to shut down threading.
The content of the invention
There is the unexpected problem for breaking to solve prior art during trimming, easily in the present invention, there is provided a kind of trimming Method, thread cutting mechanism and the embroidery machine using the mechanism.
The present invention solves a kind of thread cutting method of technical scheme of existing issue, and when embroidery machine needs trimming, step is as follows,
Step 1:Control system drives string-hooking mechanism to stretch out line hook hook and takes upper thread and pull back to appropriate location, described appropriate location To ensure that pulling out upper thread has enough surpluses.
Step 2:The line of control system control string-hooking mechanism is hooked after pulling back and departs from upper thread, and the upper thread with surplus will be lax.
Step 3:Control system control thread cutter cuts lax upper thread.
Step 4:Control system control string-hooking mechanism line hook stretch out again hook take cut upper thread in line hook on, the quilt The upper thread end of cutting is positioned at this end of embroidering pin.
As a further improvement, the line hook of control system control string-hooking mechanism stretches out disengaging face again in described step 2 Line, the upper thread with surplus will be lax.
As a further improvement, servomotor, stepper motor or straight set by described control system control string-hooking mechanism Line motor drives line is hooked and acted accordingly.
As a further improvement, the servo or driving stepper motor one set by described control system control string-hooking mechanism are driven Lever drives the line of the Xian Gou mechanisms at least one head to hook and is acted accordingly.
The present invention solves the technical scheme of existing issue:
A kind of thread cutting mechanism, including Xian Gou mechanisms, thread cutter under embroidery machine head are arranged at, Xian Gou mechanisms include that completing hook line moves The driver that the line of work is hooked, line is hooked, used as improvement, described driver is provided with controller, and described driver includes drives line Driving structure, the motor of driving structure of hook action, described motor is servomotor, stepper motor or linear electric motors, described Controller control servo or stepper motor drive driving structure drives line to hook to be acted accordingly.
A kind of embroidery machine thread cutting mechanism, including body, are arranged at least one head on body, and described head is divided into Wired hook mechanism, thread cutter, Xian Gou mechanisms include the driver for completing the line hook of line hook action, line is hooked, described as improvement Driver is provided with controller, and described driver includes motor, drive rod, is arranged at drives line hook action on corresponding head Driving structure, described motor is servomotor, stepper motor or linear electric motors, and described motor is driven respectively by drive rod Driver on head, described controller control servo or stepper motor.
As a further improvement, described controller control thread cutter trimming and the coordination of Xian Gou mechanisms.
As a further improvement, described motor shaft is provided with swing rod, described drive rod is hinged with swing rod.
As a further improvement, described driving structure includes the connecting lever being connected with drive rod, the rotating shaft of positioning connecting lever, determines The cunning that bit line hooks the slideway or chute of slip, drives line hook is slided is inserted, described line hooks the protruding shaft for being provided with and sliding inserting conjunction.
The method of the present invention and dependency structure drive string-hooking mechanism to stretch out line and hook compared with existing, by control system Take upper thread and pull back to appropriate location, making the upper thread of pull-out has enough surpluses, then control line is hooked and departs from upper thread, such upper thread In lax unstressed state, then upper thread just can accurately be cut by thread cutter, control system control is finally passed through again Line processed hooks the upper thread of cutting of pulling back and line is hooked, in case embroidering pin continues to embroider next time, its advantage be during trimming In the state of upper thread is lax, completely dispenses with worry upper thread and be pulled off, depart from from embroidering pin.The inventive method can effectively prevent or Reduce the halting problem caused by trimming.
