Abstract

The utility model discloses a thread trimming device of a flat seaming machine. The thread trimming device comprises a main baseplate component, a pressure plate component, a thread cutting seat component and an actuating arm component for driving a thread hooking seat, wherein the main baseplate component comprises a plate body, and a baffle plate and elastic pieces, which are assembled on the plate body; the pressure plate component comprise a big pressure plate and a small pressure plate; the thread cutting seat component comprises a thread cutting seat assembled on thread cutting seat component, a slide guiding pillar, a return bolt, a trimmer, and a cushion block; a thread hooking seat component comprises the thread hooking seat assembled on the thread hooking seat component and a hooking cutter; and the actuating arm component comprises an actuating arm. When the thread trimming device is mounted on the flat seaming machine with five-row or four-row cloth feeding teeth, a thread cutting cutter body is guaranteed to be closer to the cloth feeding teeth only by releasing a screw on the baffle plate to slightly rotate the thread trimming device, so as to guarantee that thread heads are shorter after threads are cut. Meanwhile, the big pressure plate and the small pressure plate adopts two long kidney slots, so that flexibility and smoothness are realized when the thread trimming device is adjusted; the elastic pieces are positioned below the thread hooking seat and cannot displace for all times when driving the thread cutting seat, which guarantee the stability and accuracy in thread cutting; the design of the thread body is simplified and only a groove is adopted, so that the structure is stable; and meanwhile, the processing procedure is simplified, and accordingly, the manufacturing cost is reduced.

Description

A kind of flat seaming machine cutting facility

Technical field

The utility model relates to the industrial sewing machine field, relates in particular to a kind of cutting facility of flat seaming machine.

Background technology

Industrial sewing machine now; generally all automatic thread trimming device is housed and has the function of automatic shearing; common automatic thread trimming device all is to drive actuating arm by drive unit to drive one and collude the side-to-side movement on the tangent line tool rest of line tool rest and finish tangent line on main substrate one big groove; usually also have two block pressur plates will collude line tool rest and tangent line tool rest to carry out linear movement and fix and finish this action; two block pressur plates are fixed by two little grooves and a screw on the main substrate; this structure is also established the block of a bending on the tangent line seat; being provided with the block that a shell fragment props up on the tangent line tool rest when actuating arm promotes to collude line apparatus and drives forwards in addition ejects the tangent line tool rest; make the tangent line tool rest near thread; yet still there is following shortcoming in practice in this device:

1, very inconvenient in the flat seaming machine one section laggard line position adjustment in period that runs up, because the structure of groove has some setbacks in debug process very much, and it is very big that groove is added the man-hour precision prescribed, causes production cost to improve.

When 2, shell fragment accessed the tangent line tool rest in the trimming process, because the flat seaming machine that runs up can produce vibrations, shell fragment was understood positioning unavoidably, thereby caused it to cut less than line or leave too much the end of a thread, influence sewing quality and efficient.

3, existing this structure makes main substrate process a big groove, and original just very thin main substrate intensity is obviously reduced, and has an external force just to be easy to distortion slightly, and whole device almost can't be worked.
