Four major problems in the development of sewing machine ind

From the trend of change after several years, our country's clothing fabrics, varieties and patterns will have great development, and the structural adjustment of sewing machines will also contribute to the great development of China's clothing industry. Personally, the following four points should be noticed in the textile industry.
1. Strong domestic demand brings opportunities. With the determination of the national health theme and the change of consumption concept, as well as the continuous improvement of people's living standards, the demand for clothing will become higher and higher, and the high demand for clothing will inevitably bring about the high demand for sewing equipment.
2. The improvement space of sewing equipment increases, which brings opportunities. With the opening to the outside world, the policy of labor export has become more and more relaxed, and with the improvement of the living standard of the Chinese people, the value of labor force has become higher and higher, which will inevitably increase the cost of garment production and even gradually lose the market price competitiveness.
3. Accession to WTO has opened up the space for garment export and brought opportunities. Before China's accession to WTO, 22% of the textile and clothing assembly quota areas and 78% of the non-quota areas were in China. After China's accession to WTO, the quota and quota limits for some restricted products in European and American markets will be abolished within 5-10 years, and China's clothing will expand from non-quota areas to export quota in 2005, which may increase by 40% to US$46 billion. At present, orders for processing in China will be increased by US$46 billion. There has been a marked increase in sewing equipment. It is necessary to update sewing equipment.
4. Renewal of market opportunities in the transformation period. The renewal cycle of industrial sewing machine is usually about 5-10 years. From the domestic situation, the early 1990s is the climax of the renewal of domestic machine to industrial machine. With the re-emergence of the garment industry, the transformation period will come again, which will certainly pull the market forward.
From some point of view, the stability, advancement and reliability of sewing machine largely depend on the assembly level of assemblers. Therefore, it can be said that the assembly level of sewing machine manufacturing enterprises also directly affects the product quality, reputation and market competitiveness of enterprises.
Sewing machine assembly details determine the success or failure of sewing machine is a mechanical product with complex design structure. If it is divided according to different requirements, the assembly methods of sewing machine can be divided into: general assembly, group assembly, dual assembly, component assembly, machine assembly, and debugging (debugging includes "adjustment" and "test run". If it is divided according to different kinds of machine assembly requirements, the assembly of sewing machine can also be divided into: synchronous, integrated, differential and other types of machine assembly.
It should be noted that the assembly of sewing machine not only refers to the assembly in the production process, but also includes the installation and debugging in the repair process.
In the production process, sewing machine assembly mainly includes six links: 1. main structure and working principle; 2. parts catalogue, parts samples, axle sleeve positioning map reading; 3. part number search, parts application, quality analysis, defect identification; 4. assembly and testing of the whole machine; 5. quality analysis of the whole machine; 6. The judgment and maintenance of machine fault.
In the process of repairing sewing machine, the assembly links are as follows: 1. Types and discrimination of common faults in the process of using products; 2. Elimination of common faults in the process of using products; 3. Installation and debugging of the whole machine in the user's environment.
If any sewing machine enterprise wants to produce a sewing machine with good quality and conforms to specifications, then the assembly process of the sewing machine in the factory must have the following two basic technical requirements: first, the precision processing of parts and components. All sewing machine parts after surface treatment such as baking paint and electroplating have sticky layers on their assembly joints (including holes, grooves, planes and screw holes). Therefore, before assembling, these parts must be finely processed according to the technological requirements before they can enter the assembly process.
Secondly, parts cleaning and cleaning. When talking about the assembly details of sewing machine, assembly worker Master Yang Huiqing said: "For our assemblers, parts cleaning and cleaning work is very important, especially for axle sleeves, bearings and other parts cleaning and cleaning work. For example, in the assembly process, if all kinds of axle parts are not cleaned strictly in accordance with the technological requirements, there will be high temperature of axle sleeve, excessive transmission torque, sand, chips and other debris clipped into it and accelerated axle sleeve wear, and even "occlusion" and other serious faults, so we must carefully do a good job of product zero. Cleaning and cleaning of parts."
