Abstract

The invention discloses a kind of anti-starting Bird's Nest systems of the controllable trimming clamp of multidigit, including rotary shuttle box, needle plate, needle plate sheath, motor, sensor stand, motor cabinet 1, motor cabinet 2, electrical machine belt pulley, cutter shaft belt wheel, synchronous belt, inductor, inductive disks a, inductive disks b, cutter shaft, trimming stationary knife, stationary knife shrapnel, trimming moving knife；To reach the product sewed without " Bird's Nest " phenomenon, realize after the completion of sewing can automatic shearing function, the anti-starting Bird's Nest system of the controllable trimming clamp of multidigit is installed additional on rotary shuttle mechanism, when starting upper thread also can form lock wire set very much on cloth with baseline in short-term；By the design, trimming moving knife clamps starting upper thread the end of a thread with the cooperation of trimming stationary knife, the line cover locking for making upper thread be formed with baseline after thread take-up tension lever action, and further action makes it cut upper thread the end of a thread to trimming moving knife, realizes starting " zero Bird's Nest "；And opened again by moving knife after sewing finishing, closed action cuts upper thread and baseline, realize automatic shearing function.

Description

The anti-starting Bird's Nest system of the controllable trimming clamp of multidigit

Technical field

The invention belongs to sewing machine technique fields, and in particular to a kind of anti-starting Bird's Nest system of controllable trimming clamp of multidigit.

Background technology

Sewing machine has all realized automatic shearing disconnection function after the completion of sewing substantially at present, and apparel industry both knows about such a Phenomenon：When machine sewn clothes, starting all can the random line pimple of output one, that is to say, that a class occurs in above fabric or bottom Like the ball of string of " Bird's Nest " shape.It is too long mainly due to starting upper thread to form this " Bird's Nest "（Starting upper thread is short can not just to be formed with baseline Line set requires to reach sewing）By the random sewing of extra upper thread the end of a thread on cloth, either household flat seam machine, Or this symptom, can all occur in industrial large-scale automatic mold trigger；Caused by harm have an impact that clothes is overall beautiful, cuts " Bird's Nest " position can waste cloth and artificial treatment but also can waste time not only, and the work holdup becomes the chicken ribs during sewing.

Invention content

In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of anti-starting Bird's Nests of the controllable trimming clamp of multidigit System, for reach the product sewed without " Bird's Nest " phenomenon again realize sewing after the completion of can automatic shearing function, need revolving The anti-starting Bird's Nest system of the controllable trimming clamp of multidigit is installed on shuttle mechanism additional come ensure very in short-term also can be in cloth in starting upper thread Upper and baseline forms lock wire set, that is, reaches starting without a ball of string, and can realize automatic shearing function, realizes that a knife is mostly used work( Can, to save the artificial reprocessing time, ensure quilt quality.

The technical solution adopted in the present invention is：

1) mechanisms make it clamp starting upper thread with the cooperation of trimming stationary knife front end Trap shell splinter using motor driving trimming moving knife.

2) locks line set by trimming moving knife, trimming stationary knife shrapnel, thread take-up tension lever.

3) is further acted by trimming moving knife, trimming stationary knife to cut extra starting upper thread the end of a thread.

4) baseline after the completion of drives trimming moving knife to carry out disposable opening and closing action cutting sewing by motor and face Line.

The anti-starting Bird's Nest system of the controllable trimming clamp of multidigit, including rotary shuttle box, needle plate, needle plate sheath, motor, sensor branch Frame, motor cabinet 1, motor cabinet 2, electrical machine belt pulley, cutter shaft belt wheel, synchronous belt, inductor, inductive disks a, inductive disks b, cutter turn Axis, trimming stationary knife, stationary knife shrapnel, trimming moving knife；The needle plate and needle plate sheath is separately fixed on rotary shuttle box, the electricity Engine base 1 is fixedly installed togather in motor cabinet 2, and the sensor stand is fixed on motor cabinet 2；The sensor stand It is separately fixed on motor cabinet 2 with electrical machine belt pulley, sensor is in the top of sensor stand；Inductive disks a and inductive disks b all with electricity Machine band driving wheel is connected, inductive disks a and inductive disks b and between have distance；Cutter runner and electrical machine belt pulley are driven by synchronous belt；Institute The trimming stationary knife and trimming moving knife stated all are fixed on rotary shuttle box, and stationary knife shrapnel is welded on trimming stationary knife.

Compared with prior art, the beneficial effects of the invention are as follows：

1) clamps starting upper thread the end of a thread by the above design organization, trimming moving knife with the cooperation of trimming stationary knife, after thread take-up tension lever action The line cover locking for making upper thread be formed with baseline, further action makes it cut upper thread the end of a thread to trimming moving knife, realizes starting " zero bird Nest ".

2）Opened again by moving knife after sewing finishing, closed action cuts upper thread and baseline, realize automatic shearing Line function.
