Sewing machine for weaving end products of Chinese knots from woolen yarn clews

Abstract

The invention discloses a Chinese knot sewing machine from a ball of wool to a finished product, which includes a frame, and the frame is sequentially provided with a thread feeding mechanism, a pulling thread mechanism, a weaving mechanism, a trimming mechanism and a coiling mechanism from top to bottom. The bottom of the frame is also provided with a sewing mechanism parallel to the winding mechanism; the sewing mechanism includes a sewing machine base, and a cylindrical cylinder is arranged on the sewing machine base, and the front end of the cylindrical cylinder is backward. cloth feeding direction; the sewing machine base is provided with a main drive shaft, a driven shaft and a transmission chain used in conjunction with it, and a compression pulley is provided on the slack side of the transmission chain; the driven shaft is provided with Needle bar driving mechanism and yarn splitting driving mechanism. The invention changes the traditional single-row design concept, realizes the technical solution of integrating woolen yarn to finished products, greatly improves the working efficiency of the sewing machine and the quality of finished products, has better safety performance, and meets the actual use requirements.

Description

technical field [0001] The invention specifically relates to a Chinese knot sewing machine from wool balls to finished products, and belongs to the technical field of sewing equipment. Background technique [0002] After the Industrial Revolution in the mid-18th century, the large-scale production of the textile industry promoted the invention and development of sewing machines. In 1970, American carpenter Thomas Settefa first invented the world's first single-thread chain stitch hand sewing machine that punches holes first, then perforates, and sews leather shoes; in 1841, French sewing B. Timonier invented And manufactured a chain stitch sewing machine with a needle and a hook; in 1845, Elias Howe in 1851, the American mechanical worker I.M. Trace sewing machine, and established the Singer Company, the sewing machines in this period were basically hand-cranked. In 1859, Singer Company invented the pedal sewing machine. After Thomas and Edison invented the electric motor,...

Problems solved by technology

When using a sewing machine equipped with this cloth return device to crease tubular cloth (such as the hem of a T-shirt, cuffs, etc.), since the crease proceeds gradually, it is necessary to keep the guide from the beginning of sewing. Back off on the road until the sewing start part of the stitch circles around the cylinder and abuts against the fabric return device; Feeding at the needle drop part cannot make the crease go around the cylinder, which will lead to sewing failure and make the sewn product unqualified

At present, there is not any kind of sewing machine that can be integrated from woolen thread to finished product in the Chinese style sewing machine of the prior art
