Abstract

The utility model relates to an automatic thread cutting device of a serger. The automatic thread cutting device of the serger comprises a support (2). The support (2) is fixedly arranged on the back face of a machine head (1) of the serger; the support (2) is fixedly provided with an air cylinder (3); the air cylinder (3) is arranged downwards; the piston rod end of the air cylinder (3) is fixedly provided with a fixed block (4); the lower end of the fixed block (4) is hinged with a connecting block (5); the connecting block (5) is fixedly provided with a jaw (6); the jaw (6) is fixedly provided with a connecting rod (7); one end of the connecting rod (7) is fixedly connected with the jaw (6); the other end of the connecting rod (7) passes through the machine head (1) to extend to the serged position of the front face of the machine head (1); and a blade (8) is fixedly arranged at the end of the connecting rod (7), which extends to the front face of the machine head (1). According to the automatic thread cutting device of the serger, after clothing is serged, the automatic thread cutting device can automatically cut off the ends of threads, therefore, the operation time of workers is saved, the continuous production can be favorably performed, and the working efficiency of the workers is greatly increased.

Description

The serger automatic tangent apparatus

Technical field

The utility model relates to a kind of serger automatic tangent apparatus.

Background technology

In producing the clothes process; Because the material that terylene etc. are used generally is synthetic fiber; Quality is harder comparatively speaking cut out after; The silk thread of cutting off the seam place, dress material limit that comes scatters because of the higher meeting of hardness ratio of itself, so need bind off: copy a circle limit at limit seam place with special-purpose serger and so as to not make that the silk thread in the cloth scatters, and so also plays effect attractive in appearance.The serger that present clothing factory generally uses just can descend subjob after all need the end of a thread being cut off after the workman binds off at every turn, influence work efficiency of workers greatly.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of serger automatic tangent apparatus is provided, and it can realize the automatic tangent after clothes bind off, and has improved work efficiency of workers greatly.

The purpose of the utility model is achieved in that a kind of serger automatic tangent apparatus, and be characterized in: it comprises support, and said support is fixedly set in the back side of serger head; Be set with cylinder on the said support, said cylinder arranges that vertically downward its tailpiece of the piston rod is set with fixed block; Said fixed block lower end is hinged with contiguous block; Be set with claw on the said contiguous block, be set with connecting rod on the said claw, said connecting rod one end is fixedly connected with claw; The other end passes head and extends to the place of binding off, head front, and extends to this positive end of head and be set with blade.

Compared with prior art, the beneficial effect of the utility model is:

A kind of serger automatic tangent apparatus of the utility model, when clothes accomplish bind off after this device can cut off the end of a thread automatically, saved workman's operating time, continuing of helping producing carries out, and improved work efficiency of workers greatly, improved the production capacity of serger.

The specific embodiment

Referring to Fig. 1, the utility model relates to a kind of serger automatic tangent apparatus, and it comprises support 2; Said support 2 is fixedly set in the back side of serger head 1, is set with cylinder 3 on the said support 2, and said cylinder 3 is arranged vertically downward; Its tailpiece of the piston rod is set with fixed block 4, and said fixed block 4 lower ends are hinged with contiguous block 5, are set with claw 6 on the said contiguous block 5; Be set with connecting rod 7 on the said claw 6; Said connecting rod 7 one ends are fixedly connected with claw 6, and the other end passes head 1 and extends to the place of binding off, head 1 front, and extend to head 1 this positive end and be set with blade 8.

The infra-red detection device control that said cylinder 3 is bound off and located by serger head 1 front; When after the clothes process is bound off, removing; The infra-red detection device provides signal, and this moment, cylinder 3 began action, and the transmission through fixed block 4, contiguous block 5, claw 6 and connecting rod 7 makes blade 8 actions; Thereby cut-out the end of a thread realizes that serger gets automatic tangent.

Claims (1)

1. serger automatic tangent apparatus; It is characterized in that: it comprises support (2), and said support (2) is fixedly set in the back side of serger head (1), is set with cylinder (3) on the said support (2); Said cylinder (3) is arranged vertically downward; Its tailpiece of the piston rod is set with fixed block (4), and said fixed block (4) lower end is hinged with contiguous block (5), is set with claw (6) on the said contiguous block (5); Be set with connecting rod (7) on the said claw (6); Said connecting rod (7) one ends are fixedly connected with claw (6), and the other end passes head (1) and extends to the place of binding off, head (1) front, and extend to this positive end of head (1) and be set with blade (8).
