Description

Technical Field

[0001] The utility model relates to the technical field of embroidery equipment, in particular to a head component of embroidery equipment. Background Art

[0002] Embroidery machine, from the literal meaning, I think everyone should understand, embroidery machine, embroidery machine, or embroidery machinery. When embroidery first started to break away from hand embroidery, the so-called embroidery machine at that time was not a real embroidery machine, because the embroidery machine at that time was a traditional sewing machine, replaced with a bottom plate with small round holes, the sewing machine needle kept going up and down, plus the hand-held embroidery frame stretched the cloth back and forth. In fact, this so-called embroidery machine, in the embroidery machine, contains a machine head component, which can effectively drive the embroidery needle to embroider on the cloth.

[0003] Among the publicly authorized patents, in the Chinese patent with the patent number "CN201510145936.8", an embroidery machine head component is disclosed. A spring-needle embroidery machine head includes a head body, a static iron core and a moving armature are arranged in the head body, a coil is wound around the static iron core through a coil frame, an ejection spring is arranged between the moving armature and the static iron core, a guide rod is fixedly installed at the bottom of the moving armature, a guide sleeve is installed outside the guide rod, and an embroidery needle is installed at the bottom of the guide rod. The embroidery needle on the spring-needle embroidery machine head of the present invention does not follow the movement of the head during the embroidery stage, but uses the elastic restoring force to move downward rapidly to embroider the cloth. Compared with the mode of overall movement embroidery in the prior art, the deformation of the fabric caused by embroidery is reduced, the difficulty of plate making is reduced, and the accuracy of the embroidery position and the aesthetics of the embroidery are improved;

[0004] It is pointed out in the above device that when the embroidery device is in use, the embroidery machine head will drive the embroidery needle to move up and down, and at the same time the embroidery needle moves on the cloth. When the embroidery needle contacts the cloth, it will cause the cloth to deform. In addition, the cloth is limited by installing limiting devices around it, which will cause excessive tension in the middle of the cloth. When the embroidery needle moves to the middle of the cloth and embroiders, the deformation of the cloth will cause the embroidery needle to affect the embroidery efficiency of the cloth during the embroidery process. For this reason, we propose a head component of an embroidery device. Utility Model Content
