An automatic cross-stitch needle threading device

Abstract

The invention relates to an automatic cross-stitch needle threading device. The automatic cross-stitch needle threading device comprises an upper needle-clamping mechanism, a lower needle-clamping mechanism, a needle-clamping transmission device and a driving device, wherein the upper needle-clamping mechanism is arranged above embroidery cloth; the lower needle-clamping mechanism is arranged below the embroidery cloth; the upper needle-clamping mechanism is used for clamping an embroidery needle, driving the embroidery needle to pass through the embroidery cloth from top to bottom, looseningthe embroidery needle after the embroidery needle passes through the embroidery cloth, and delivering the embroidery needle to the lower needle-clamping mechanism; the lower needle-clamping mechanismis used for clamping the embroidery needle, driving the embroidery needle to pass through the embroidery cloth from bottom to top, loosening the embroidery needle after the embroidery needle passes through the embroidery cloth, and delivering the embroidery needle to the upper needle-clamping mechanism. By designing the number of teeth of a first upper incomplete gear and a second upper incompletegear, the number of teeth of a first lower incomplete gear and a second lower incomplete gear, and the transmission time gap between the two pairs of gears, accurate control of the timing of downwardneedle threading, lower needle receiving, upward needle threading and upper needle receiving is realized, and the process of manual cross-stitch embroidery can be simulated completely. The device iseasy to operate.

Description

technical field [0001] The invention relates to embroidery equipment, in particular to an automatic cross-stitch needle threading device. Background technique [0002] Cross-stitch is commonly known as "cross-stitch" or "pick-and-patch embroidery" among the people. As early as the 4th century AD, cross stitch spread from Turkey to Europe via Italy. Cross-stitch is an ancient national embroidery with a long history. Now cross-stitch has come to China and has been applied and developed in China. People are adding some modern high-tech techniques according to traditional techniques, making it a sunrise industry. The cross-stitch industry will definitely become a competitive and complete industrial chain with long-term prospects in China. [0003] Although the current cross-stitch is so widely spread in countries all over the world, there is still no feasible plan in countries all over the world for the research of using machines to replace traditional hand-made crafts to en...
