Description

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

Technical field

The utility model belongs to sewing machine technique field, and in particular to a kind of anti-withdrawal of needle Bird's Nest system of the controllable trimming clamp of multidigit System.

Background technology

Current sewing machine has all realized automatic shearing disconnection function after the completion of sewing substantially, and apparel industry both knows about such a Phenomenon：During 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.Form this " Bird's Nest " oversize mainly due to withdrawal of needle upper thread（Withdrawal of needle upper thread is short can not just to be formed with bottom line Line set, so as to can not reach that sewing is required）By the random sewing of unnecessary upper thread the end of a thread on cloth, either family expenses flat seam machine, Or this symptom, can all occur in industrial large-scale automatic mold trigger；The harm caused has an impact clothes overall appearance, cut " Bird's Nest " position can waste cloth and artificial treatment but also can lose time not only, and the work holdup becomes the chicken ribs during sewing.

The content of the invention

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of controllable anti-withdrawal of needle of trimming clamp of multidigit Bird's Nest system, for reach the product sewed without " Bird's Nest " phenomenon realize again sewing after the completion of can automatic shearing function, it is necessary to The anti-withdrawal of needle Bird's Nest system of the controllable trimming clamp of multidigit is installed additional on rotary shuttle mechanism come ensure very in short-term also can be in withdrawal of needle upper thread With bottom line formation lock wire set on cloth, that is, reach that withdrawal of needle, without a ball of string, can realize automatic shearing function again, realize that a knife is used Function, so as to save the artificial reprocessing time, ensures quilt quality.

The technical scheme that the utility model is used is：

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

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

3) further acts to cut unnecessary withdrawal of needle upper thread the end of a thread by trimming moving knife, trimming stationary knife.

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

The anti-withdrawal of needle 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, cutting knife rotating shaft belt wheel, timing belt, inductor, inductive disks a, inductive disks b, cutting knife turn Axle, trimming stationary knife, stationary knife shell fragment, trimming moving knife；Described needle plate and needle plate sheath is separately fixed on rotary shuttle box, described electricity Support 1 is fixedly installed togather in motor cabinet 2, and described sensor stand is fixed on motor cabinet 2；Described sensor stand It is separately fixed at electrical machine belt pulley on motor cabinet 2, sensor is in the top of sensor stand；Inductive disks a and inductive disks b all with electricity Machine driven wheel is connected, inductive disks a and inductive disks b and between have distance；Cutting knife runner and electrical machine belt pulley are driven by timing belt；Institute The trimming stationary knife and trimming moving knife stated all are fixed on rotary shuttle box, and stationary knife shell fragment is welded on trimming stationary knife.

Compared with prior art, the beneficial effects of the utility model are：

1) is by above design organization, and trimming moving knife coordinates with trimming stationary knife clamps withdrawal of needle upper thread the end of a thread, dynamic in thread take-up tension lever Make upper thread and the line cover locking of bottom line formation after work, further action makes it cut upper thread the end of a thread to trimming moving knife, realizes withdrawal of needle " zero Bird's Nest ".

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