Stitch pressing and cutting device of overlock stitching machine

Abstract

The invention relates to a stitch pressing and cutting device of an overlock stitching machine. The stitch pressing and cutting device of the overlock stitching machine is mainly characterized in that a pressing and cutting device is arranged and connected with an overlock stitching machine table, the pressing and cutting device is provided with an elastic gripping piece on the outer side corresponding to a working platform of the overlock stitching machine, the pressing and cutting device is provided with a pushing power source corresponding to the overlock stitching machine, the pushing power source can drive a cutter to swing, a moving cutting edge is arranged at the upper end of the cutter corresponding to the outer end of the elastic gripping piece and a fixed cutting edge is arranged at a position corresponding to the moving cutting edge. Therefore, the stitch pressing and cutting device of the overlock stitching machine has the advantages that the gripping and cutting action can be automatically performed to a netted section of stitches after an object is stitched, the cut netted section can be kept to be gripped at the front of a needle plate, the overlock stitching operation can be conveniently and directly performed after the next object is put inside, not only is the stitching operation more smooth, simple and convenient, but also the man hour spent in the stitching process can be relatively reduced, the netted section of the stitches after stitching can be kept in a fixed range, the function of saving threads is achieved and the practical effect is more greatly increased in overall implementation and use.

Description

technical field [0001] The invention relates to a sewing thread pressing device for an overlock sewing machine, in particular to a device that can automatically press and cut the netting section of the needle thread after sewing, and at the same time keep the cut netting section under pressure. The button is placed in front of the needle plate, which is convenient for overlock sewing to be performed directly after the next object is placed. The netting section of the rear needle thread is kept within a fixed range to achieve the function of saving thread consumption, and the innovative designer of the overlock sewing machine suture pressing device with more practical and functional features in its overall implementation. Background technique [0002] Press, the general overlock sewing machine is mainly equipped with a motor on the machine table, and then the motor is linked with the drive shaft of the overlock sewing machine to drive the various parts to move and the needle ...

Problems solved by technology

[0003] However, although the above-mentioned overlock sewing machine can achieve the expected effect of sewing objects, it is also found in its actual implementation that the operator needs to take the scissors separately after sewing an object with the overlock sewing machine. Use scissors to cut off the knotted net section as the finishing action of the sewing of the object, and prepare for the next object to be sewn, and in order to have enough space to cut the thread with scissors, usually after the sewing object is completed The netting section of the knot will stay very long, which not only causes the waste of sewing threads, but also manually takes the scissors to cut the netting section of each object that has been sewn by the car. It is extremely inconvenient and requires relatively more tasks, so there is still room for improvement in the overall structural design
