The 2023 new spring festival " old times in old articles " , launched by the museum of xinxi county, focused on the development of the economy and society of xinxi since the establishment of the new china, and brought us back to the forgotten period with a multifaceted perspective。
I used to do it all the time
With regard to sewing machines, the history of which dates back to the chinese knitting machine of song yuen chudo, which can be called the “premature of sewing machines”; after the industrial revolution in the mid-eighteenth century, textile technology began to move towards industrial sewing technology, and the world's people were exploring various kinds of sewing technology to liberate productivity。
At the end of the 1950s, the light industry introduced universalization and standardization of domestic sewing machines, harmonized design drawings and improved compatibility of spare parts, resulting in a growing number of sewing machines. As of 1980, there were 56 sewing machines in 22 provinces and municipalities. By 1982, our sewing machines had reached 1,286,000, the highest production in the world。
In the latter part of the 1990s, private enterprises began to emerge, and the major restructuring of the industrial structure contributed to the development of the industry。
As of 2004, there were more than 600 sewing machines in the country, with more than 1,000 spare parts producing more than 148,000 units per year, with a total production value of approximately 28 billion yuan and a variety of nearly 1,000 units, and one of the world's leading producers of sewing machinery。
The general sewing machine consists of the pilot, the seat, the movement and part of annex iv。
The head is the main part of the sewing machine. It consists of four auxiliary bodies, such as stings, hooks, pickers, delivery units and bypasses, pressurized substances and teeth drops. The agencies ' movements are well coordinated, and they work in a circular fashion to stitch up the sutures。
The seating is in the form of two panels and boxes. The tablets in the desktops function as a backstop and are used as workshops for sewing operations. The tablets are in a variety of forms, with one or more collections, cabinets, writing lines, etc. The trunks of the aircraft are used to support and store the head of the aircraft, so that sewing machines can be carried and kept。
The transfer element of the sewing machine consists of parts such as racks, handshakers or electric motors. The racks are the pillars of the machine and carry the plates and pedals. When used, the operator presses the pedal, rotates the wheel through the handle, and rotates the head through the belt. Most of the handshakers or electric motors are placed directly on the aircraft。
The attachments to sewing machines include needles, props, knives, kettles, etc。
The method of sewing:
The core of the sewing machine is the coil suture system. The sewing machine only needs a piece of needle through the fabric. On the needle, the needle is behind the tip, not at the end of the needle. The needles are fixed to the needles, which are moved upwards and down by electricians through a series of gears and cams (detailed later). When the tip of the needle passes through the fabric, it pulls out a small circle on the other side. A device below the fabric will grab the circle and wrap it around another line or another circle of the same line。
