Talking about the status quo of mechanical and electrical integration technology of sewing machine

At present, China's electronically controlled motor technology has developed rapidly. In the sewing machine industry, mechanical and electrical integration is relatively weak. Actively promoting motor and electronic control enterprise cooperation and mergers and acquisitions is also one of the key tasks for the current industry upgrade and development.

In order to keep pace with international development trends, seize the cutting-edge technologies of international sewing machinery, face the technical problems that the country and society urgently need to solve, and aim at the status quo of Zhejiang Province's economy and the industrial technology of this industry, we should focus on the “machines” in mechatronic products. The structure of the two key components of "electricity" is studied in depth.

To understand the application of direct-drive research technology to research the organic combination of emerging direct-drive application technology and sewing machinery, we should use a combination of simple and complex, high-level and low-level coexistence to study its development in multiple levels. As China's strategy for developing a low-carbon and green economy is established, future competition among enterprises will be based on low-carbon technology and product competition. Promoting green development is an important focal point for transforming development methods. For the sewing machinery industry, we must develop a green economy and develop into a resource-saving and environment-friendly industry. Direct-drive technology will be the focus of future development.

In the era of computer control, the adoption of the structure of direct-drive motors is a major breakthrough in the use of mechanical and electrical integration technology in the structure of sewing machines. It lays the foundation for the development of sewing machine structural integration technology, and the development trend marked by structural integration is inevitable. The control part, drive part and mechanical part of the sewing machine are integrated into the head of a sewing machine. This not only reduces the subsequent installation requirements of the machine, but also reduces unnecessary technical problems caused by the user's unfamiliarity with the installation of the machine. Improve the efficiency of use of the machine and make the appearance of the device more concise and beautiful.

Advantages and Problems to be Solved by Using a Direct-drive Motor The direct-drive motor and the spindle of the sewing machine are integrated into a single unit. They are connected by flanges or bushings. The drive method does not need to be transmitted by a belt, which can effectively avoid the motor belt. The energy loss and slippage caused by the transmission, as well as the resulting failure caused by belt debris. According to incomplete statistics, the energy saving effect of sewing equipment with direct-drive energy-saving motors is at least 15% higher than that of the sewing equipment equipped with ordinary energy-saving motors, and the positioning is more accurate and the response is more sensitive.

Because the direct drive motor is installed inside the casing, the heat and heat dissipation conditions of the overall design of the motor are more stringent. This requires the designer to consider the high speed operation of the motor design of the electromechanical integration sewing machine. It generates less heat, while applying new materials, new structures, and new processes to greatly improve heat dissipation.

In addition, the electronically controlled direct drive motor is the first to be used in the sewing machine. Due to the large size of the sewing machine, the speed, precision, service life, and production cost all have outstanding performance. It has become large-scale and gradually replaced. Traditional sewing machine. However, it is undeniable that, at present, both the domestic and foreign direct-drive technology of the sewing machinery industry needs to be further improved. In particular, the application of electronically controlled direct drive has resulted in a significant increase in the speed of sewing, and manufacturing of corresponding mechanical parts and components. Inspection standards have not been improved, resulting in more machine faults, bearing bending and crank fracture failure phenomenon.

Requirements for reducing the consumption of materials At present, sewing machinery companies in various countries in the world generally use new materials in their designs. Under the circumstance that the power of the motor is kept constant, the size (including diameter and length) of the motor is minimized, and at the same time, Strong heat dissipation performance.

Direct-drive motors have many new requirements in terms of processing technology: The motor must be small in size and must be installed in a small internal cavity of the housing; generally, the motor is small in size and the output power is small, and the direct drive motor must satisfy the output. Large power requirements require improvements in the structure, magnetic field, and material design of the motor.

At present, China's sewing machinery industry has a great interest in the new type of motor and the urgency of the localization of the contradiction can not be avoided, but in the current situation, the domestic professional production of electronic control and motor manufacturers to develop, some are focused on the motor Without electronic control, it is bound to cause some companies that do electronic control not to pay much attention to the innovation of motors, and to make the technological innovation in the motor production field of the sewing machinery industry fall into the dilemma of dilemma. At present, the development of the domestic electronically controlled motor technology innovation in harmony and unity is still difficult to achieve in this field. Actively promoting motor and electronic control enterprise cooperation and merger and reorganization is also one of the key tasks for the current industry upgrade and development.

The state's control over some of the important raw materials of the motor has caused its price to increase several times. At the same time, the corresponding costs of internal technology research and development, production management, and human resources continue to increase. This has led to difficulties in the quality, quality and profitability of motor manufacturing companies. Therefore, motor manufacturers in the sewing machinery industry should improve the quality of their products while relying on scientific cost control to ensure a reasonable profit margin.

The author believes that the success of a company does not represent the progress of an industry. The motive force for the development of a company is not from the decision-making but from competitors. Mechatronics technology must be truly at the forefront of historical development, and it must not forget the burden of industry development. The construction of a technological development platform will form a comprehensive situation for technology sharing and lead the sewing machinery industry to achieve a comprehensive transformation and upgrading.
