From the opening of the first small workshop in Shanghai in 1905 to manufacture sewing machine parts and accessories, today the production of sewing machines accounts for 70% of the world. China has become the world's largest producer of sewing machines. The progress of China's sewing machines on the road of industrial development has attracted worldwide attention.
As the sewing industry, such as clothing, home textiles, shoes and hats, bags and bags, proposes newer and higher requirements on the quality, efficiency and function of sewing equipment, the sewing machinery manufacturing industry must of course have various technical performances and parameters in the sewing equipment. And comprehensive functions, grades and other aspects continue to improve and innovate to meet the various requirements of customers. Looking at modern sewing machines, we believe that they have the following main features:
First, in order to adapt to the continuous improvement of sewing efficiency, the speed of sewing machine is constantly improving. In the development process of sewing machine, sewing speed is one of the most important technical parameters. The symbol of continuous upgrading of sewing technology is that the sewing speed is constantly accelerating. Upgrade. In the early days of the founding of the People's Republic of China, China could only produce JA and JB pure mechanical household sewing machines with a sewing speed of no more than 1500r.pm. In the 1960s and 1970s, it was developed to produce GC and GN medium speeds with a seam speed of 3000r.pm. Industrial sewing machine; after the mid-1980s, it developed into a high-speed industrial sewing machine capable of producing sewing speeds of 3500~4000r.pm and high-speed industrial sewing machines of 4500 and 5000r.pm; now, the sewing speed of domestic sewing machines has reached 5500, 6000, 8000r. The level of .pm, and the realization of mechatronics, some ultra-high-speed industrial sewing machines, such as JK-798 super high-speed overlock sewing machine, rated speed of 8000r.pm (foreign also has a rated sewing speed of 10000r.pm package Sewing machine, although its real use occasion is limited).
The faster the sewing speed, the better? This requires specific analysis of specific issues.
The sewing speed is not only related to the material and thickness of the fabric used by the user, the material of the suture, the twist, the direction of rotation, the size of the needle and the size of the needle and its needle-edge section, but also the length of the seam required for the sewing product. , bending and whether to reverse the sewing.
Garment production, especially foreign trade processing, rushing orders, ensuring quality and delivery time is the key to trade success. From the user's point of view, sewing speed is a historical necessity.
Second, the sewing machine control, transmission mechanism, light-machine-electric-liquid (gas) pressure integration is gradually popularizing the light-machine-electric-hydraulic (or pneumatic) integration is to adapt to the use of optoelectronics, digital technology in the sewing machine industry The major technological revolution can be said without exaggeration: Whoever's light-machine-electric-hydraulic (or pneumatic) integration technology is doing well, who will seize the opportunity in the future competition. China, light-machine-electric technology is still lagging behind abroad; Jack, light-machine-electric technology is just getting started, and Jack's independent new product integration research and development (IPD) is still in the midst of a small test, but the newborn calf is not afraid of tigers. The latecomers will definitely be on the list. Such as: JK-8990/91/92 high-speed computer-controlled sewing machine has been successfully driven by built-in servo motor. JK-5878 high-speed automatic bag opening--sewing machine adopts light-machine-electric-pneumatic control. In recent years, Jack's batch of optical-machine-electrical integration new products have been favored by domestic and foreign users and distributors since entering the domestic and foreign markets. Currently, the "flat-stretch combination sewing machine" is being further developed. The new range of products will enable the application of opto-mechanical-electrical technology to a higher level. Drawing on the advanced experience of domestic and foreign research institutes and enterprises, some of the automation levels of Jack's sewing machine products have reached or approached the advanced level in the industry. Jack-stitching machine-light-machine-electricity integration will certainly have more progress.
Third, the continuous improvement and promotion of non- (micro) oil technology will promote the leap of domestic sewing machine
Tests have shown that when the relative motion linear velocity of the mechanical movement reaches 10 m / s, if the oil is not refueled in the working condition without allowing dry friction, the surface of the mutually moving component material will rapidly heat up - coking - biting. Taking the high-speed sewing machine with a sewing speed of 5000r.pm as an example, the relative linear speed of the hook guide rail is about 15m/s. If the fuel is not refueled in time or effective measures are taken, the moving auxiliary member heats up - coking - biting The process of death will be even more dramatic. Medium and low speed sewing machines usually use manual oiling or smearing of conventional lubricating grease. High-speed sewing machines use different types of oil pumps for centralized forced oil supply. Generally speaking, the higher the "sewing speed", the greater the pump oil pressure, but forced Under the influence of various factors, the oil supply will inevitably have the phenomenon of oil spill, leakage and seepage, and thus will cause pollution to the sewing material. The contradiction between the improvement of the sewing speed and the absence of oil leakage has once become a key factor restricting the development of sewing machines. The micro-oil and oil-free sewing machines that many sewing machine manufacturers at home and abroad have introduced in recent years are the "reverse new" innovations for the pollution defects caused by the overflow, leakage and seepage of lubricating oil. After a large number of anatomical tests, the common point of the above-mentioned "creative" is that the traditional sewing machine has undergone partial structural modification and transformation, and the "solid lubricant" which is different from the traditional lubrication principle has been maintained with relevant domestic and foreign institutions. The company's cooperation in non-(micro)oil technology, in addition to joint research with engineering and technical personnel of polymer chemical companies such as Shanghai and Wenzhou on polymer engineering plastics, high temperature resistant, low noise solid grease trials, etc. A large number of continuous operation test analyses were performed on different types of "oil-free rotary hooks" provided by various component manufacturers. At present, the data collection, analysis and improvement of the pilot project has been completed, and some related high-tech technologies have been applied to the product. Judging from the operational effects of the launch of the market, some of the technical applications have already taken the lead in the country and are very popular.
In addition, special sewing machines designed for specific processes, composite stitch sewing machines designed with different sewing processes, and low-tension multi-function sewing machines designed with double positioning eccentric hooks are also available in modern sewing machines. The characteristics of our technology research and development team are step by step.
In short, labor-saving, high-efficiency and automation represent the highest level and development trend of today's sewing equipment production; the independent development of “multi-function, composite stitch, multi-purpose†sewing machine, in a sense also represents the total sewing machine R&D trends.
China is a big country in the world of garment production, and also a major producer of sewing machinery in the world. It should become a world leader in sewing machine production!
Known as the "black horse" in the Chinese sewing industry, Jack is working with Hanjie Consulting to develop a first-class R&D system in the development of modern sewing machinery. After careful review of the R&D process and reconstruction of the technology platform, it will definitely be Design and produce a new generation of sewing machines with more, better, superior quality and full functions for the users in the sewing industry.
