Technical points for the development of domestic special sewing machines

Special sewing machineDue to its high technical content and complex structure, the investment in research and development is relatively high, and the relative price is relatively high. Although this is conducive to the introduction of electronic technology, it is also extremely easy to make detours. Therefore, it is very important to grasp the key points and methods for the development of special sewing machine technology. Here is a brief introduction to the main points of the development of special machines.

The first is the basic technology of special sewing machines, namely the sewing mechanism. It is the basis for the independent innovation and development of sewing machines. Foreign countries have done a lot of basic research on hooks, loops and interlock sewing technologies. The basis for the development and improvement of seams and interlock seams is also the basis for the research and development of special sewing machines. With these foundations, the development of new sewing machines, the improvement of sewing performance, the development of needle position parts suitable for various fabrics, the introduction of electronic technology, and the digital control of sewing performance can all be implemented smoothly. Fortunately, these work have been carried out in some domestic large-scale enterprises, which also indicates that my country's special sewing machine development will enter a period of truly independent innovation.

The second is oil-free technology. Oil-free is a new trend in the development of special sewing machines, and the technology is becoming more mature. At present, the sewing speed of most special sewing machines is relatively low, and it is easy to realize oil-free. The oil-free of the sewing machine mainly refers to the oil-free of the head of the sewing machine. Of course, further development can be oil-free rotary hook and oil-free whole machine. The oil-free technology of the machine head mainly includes oil-free thread take-up components and oil-free needle bar. Among them, the current method for thread take-up components without oil is mainly to use sealed grease ball bearings, which are applied to special sewing machines with relatively low speed.

The third is electronic control technology. The introduction of electronic control technology in special sewing machines is much more effective than ordinary sewing machines, especially the use of electronic control technology in cycle sewing machines, which can greatly simplify the mechanical mechanism and eliminate the easy-to-wear cam and wheel transmission. In addition, the use of motor control timing is much more reliable than mechanical control, and it is easy to achieve oil-free. At present, the electronic control technology of special sewing machine mainly includes servo motor technology, stepper motor technology, multi-function electromagnet design, solenoid valve technology, system drive controller and LCD/PDA man-machine interface, etc.
