Automatic thread trimmer

Abstract

The invention discloses an automatic thread trimmer. The automatic thread trimmer comprises a mounting plate, two symmetrical combination plates are fixedly connected to the right side of the mounting plate, hinge pieces are fixedly connected to the sides, close to each other, of the combination plates through connecting rods, and two symmetrical power rods and two symmetrical shearing plates are correspondingly and movably connected to the left sides and the right sides of the hinge pieces. The sides, close to each other, of the two combination plates are fixedly connected with a guide plate located on the left side of a hinged plate. A driving motor and a driving tooth block are arranged to enable a traction gear to pull a shearing plate to perform reciprocating thread shearing work, the guide plate and a guide groove are arranged to limit the motion trail of a thread shearing structure, and a reset spring is arranged to perform reset pulling after thread shearing work is finished. Therefore, deviation of the trimming horizontal height and position is avoided, the effect of improving the trimming efficiency is achieved by ensuring that deviation and errors of the trimming position are avoided, and the effect of improving the overall working efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of embroidery machines, in particular to an automatic thread cutter. Background technique [0002] An embroidery machine is an embroidery machine, or an embroidery machine. When embroidery first started to break away from manual embroidery, the so-called embroidery machine at that time was not actually an embroidery machine in the true sense, because the embroidery machine at that time used a traditional sewing machine. A bottom plate with a small round hole, the sewing machine needle keeps going in and out, and the cloth stretched by the embroidery frame is moved back and forth. In fact, this so-called embroidery machine is still hand embroidery. A sort of.

Problems solved by technology

[0003] With the increasing use of embroidery machines, the requirements for embroidery machine thread trimming devices are also increasing. However, the existing embroidery machine thread trimming devices are prone to deviation and great errors because of the horizontal height when cutting the thread. It affects the normal thread trimming efficiency, which directly affects the normal embroidery machine work efficiency
