(1) history
In 1790,
St. Thomas of England invented the hand sewing machine for sewing the single chain stitch of boots and shoes.
This sewing machine is made of wood and some parts are made of metal.
It was the world's first sewing machine.
In 1841, the French timenier designed and manufactured the practical two-line chain-stitch sewing machine.
In 1846, the United States was awarded the patent for the curved lockstitch sewing machine with a sewing speed of 300 stitches/min, more than five hand-operated sewing technicians; In 1851, American mechanical worker shengjia designed and manufactured shengjia sewing machine independently. The sewing speed was 600 stitches/min, and the American patent was obtained in 1853. Since then, the sewing machine began to be used in large quantities, and gradually added button fastening, button hole, reinforcement, embroidery and other functions. In 1975, the United States invented the microcomputer-controlled household multi-function sewing machine. The development of professional industrial sewing machines is more extensive and the sewing speed is increasingly high. For example, the overlock sewing machine has reached 10,000 stitches/min. In 1979, the total output of the world sewing machines reached 15885,000, among which China produced 5870000, which is the country with the highest output of sewing machines in the world. A sewing machine is a machine in which one or more sewing threads are used to form one or more stitching traces on the stitching materials to make one or more layers of stitching materials interweave or sew together. Sewing machine can sew cotton, hemp, silk, wool, man-made fiber and leather, plastic, paper and other products.
(2) the general principle of sewing machine is composed of the machine head, machine base, transmission and accessories. The machine head is the main part of the sewing machine. It is composed of four mechanisms, such as puncture material, hook line, stripper line and feed material, as well as auxiliary mechanisms such as winding wire, pressing material and falling tooth. The movement of each mechanism is reasonably coordinated and works in a circular manner to suture the suture material. The machine stands are divided into two forms: platform and case. The platform plate of the machine seat plays the role of supporting the machine head. The platen has a variety of style, have a bucket or many bucket fold Tibetan type, cabinet type, write desk type to wait. The case of the case seat plays a role of support and storage head, making the sewing machine easy to carry and keep. The driving part of the sewing machine is composed of a frame, a hand shaker or a motor. The frame is the support of the machine, supporting the platform and foot pedal. The operator moves the foot pedal when using, drives the pulley rotation through the crank, and the machine head rotation through the belt. Most hand - operated or electric motors are installed directly on the nose.
Second, the status quo
With the rapid development of the clutch motor market for industrial sewing machines in China, the application and research and development of related core production technologies will be the focus of the enterprises in the industry. Industrial sewing machines are different from household sewing machines. Its machine type, power, function and price have very big difference. Industrial sewing machine is a single-function sewing machine with high power and speed. There are high - level machine, overlock machine, keyhole machine, button, stretching machine and so on machine type, each machine type has many subdivisions. For example, high machine, and suitable for thin, medium and thick materials, can automatically cut wire and other different models. Domestic sewing machines usually have an electric speed of around 900 RPM. The new type household machine is the multi-function sewing machine, can do the straight sewing, the twist sewing, the nail buckle, the lock keyhole, the simple locking edge, the sewing decoration lace, the free embroidery and so on. Computer embroidery machine can also according to your needs to embroider different colorful embroidery products. According to different processing products and output, different sewing equipment can be configured, which can be mixed and matched between industrial sewing machine and household sewing machine. Shengjia has a variety of industrial machines, household multi-functional machines, computer embroidery machine for your choice. At the beginning, household sewing machines were basically single-needle, hand-operated sewing machines. Later, the invention of electric driven sewing machines has been the mainstream in the market. According to different processing products and output, different sewing equipment can be configured, which can be mixed and matched between industrial sewing machine and household sewing machine
Most of the industrial sewing machines, industrial sewing machine belongs to general sewing machine, including the flush joint machine, chain stitch machine, overlock machine and flat seaming machines, sewing machines and sewing machine top utilization rate of development of improving the level of the original model, at the same time a large number of developed ShengLiHua, de-skilled, automation and efficiency of the model as well as other electronic control automatic costume attached to the product.
Third, in the future
I think in the future sewing machines will be highly automated. As a representative of the advanced equipment manufacturing industry in light industry, China's sewing machinery industry not only vigorously promotes the intellectualization of the manufacturing process, but "Internet +" is also a major trend of the industry's future development. In fact, long before the concept of "Internet +" was proposed, China's sewing equipment industry was already at a high level in terms of information application and development of industrialization and information integration. According to industry statistics, at present the industry in the field of product for seven classes based on Internet of things technology products, dozens of companies around the above products in the related research and development innovation, typically have a visa, leap binaries, otake, companies such as radio frequency identification technology (RFID) based intelligent hanging conveyer system and intelligent storage system, Shanghai and the eagle clothing flexible manufacturing system based on network database, etc. For the industry, concepts and technologies such as the Internet of things and cloud computing are really at the initial stage of application integration. For the new thing industry, it should first have positive ideas, advance with The Times, and integrate "Internet +" comprehensively from its own reality. To actively carry out based on the "+" Internet products and business model innovation, "Internet +" in technology is essentially the traditional industry of network, digital, to complete the sewing machine "" Internet + products and business model innovation, first of all to achieve industry all kinds of basic data, data such as product design, production, market and customer demand for data collection and data interconnection; We should actively promote the innovation of products and service application of "Internet + sewing machinery", and actively improve and constantly interpret the concept and connotation of "Internet + sewing machinery".
