"Machine" And "Electricity" Should Develop One By One -- Talking About The Research Status Of Mechanical And Electrical Integration Technology Of Sewing Machine

In order to keep pace with the international development trend, grasp the frontier technology of International Sewing machinery, face the technical problems that the state and society urgently need to solve, and aim at the economy and capital of Zhejiang province.

To study the organic combination of new direct drive application technology and sewing machinery, we should study the development at different levels by using both simple and complicated methods.

With the establishment of a low-carbon green economy strategy in China, the competition among enterprises will be based on the competition between low carbon technology and products. Promoting green development is an important point in changing the way of development.

For sewing machinery industry, we must develop green economy and develop it into a resource conserving, environment-friendly and friendly industry. Direct drive technology will be the focus of future development.

In the age of computer control, the structure of direct drive motor is electromechanical integration technology.

The direct drive motor and the spindle of the sewing machine are integrated into a whole, connected by flanges or bushings, and the driving mode does not need to be pmitted by the belt. It can effectively avoid the energy loss and slippage caused by the pmission of the motor belt, and the fault caused by the belt debris.

According to incomplete statistics, the energy saving effect of the direct driven energy saving motor's sewing equipment is at least 15% above that of the sewing machine equipped with the ordinary energy-saving motor, and the positioning is more accurate and the reaction is more sensitive.

Because the direct drive motor is installed inside the chassis, the motor has strict requirements for the heating and heat dissipation of the overall design of the equipment. This requires the designer to take into account the less heat generated during the high-speed operation when designing the motor for the mechatronics sewing machine. At the same time, the new material, new structure and new technology are applied to greatly improve the heat dissipation performance.

In addition, the electronically controlled direct drive motor is first applied in the sewing machine. Due to the large volume of the sewing machine, it has shown prominently in speed, accuracy, service life and production cost, and has formed a large scale and gradually replaced the traditional sewing machine.

However, it is undeniable that at present, the direct drive technology of sewing machinery industry at home and abroad needs further improvement. In particular, the application of electronically controlled direct drive has greatly improved the sewing speed. The manufacturing and testing standards for corresponding mechanical parts manufacturing have not been improved, resulting in more malfunctions such as poor machine trimming, bearing bending and crank fracture.

At present, the sewing machinery enterprises in the world generally use new materials in the design. Under the condition that the motor power is kept constant, the motor volume (including diameter and length) is reduced to the maximum, and at the same time, it requires strong heat dissipation performance.

Direct drive motor has many new requirements in the processing technology: the motor volume is small, and must be installed in the inner cavity of the small housing. Generally, the motor is small in size and the output power is small, and the direct drive motor must meet the requirements of large output power, so the structure, magnetic field and material design of the motor need improvement.

At present, the sewing machine industry in China is interested in the new motor and the contradiction between the urgent needs of localization is inevitable. However, according to the development of the domestic professional production of electronic control and motor manufacturers, some focus on the motor and do not make electronic control, and some enterprises that do electric control will not pay much attention to the innovation of the motor, so that the technological innovation in the field of motor production in sewing machine industry is also in a dilemma.

At present, the development of electric motor technology innovation and harmoniously in China is still hard to achieve in this field. It is also one of the key tasks of the current industry upgrading to actively promote cooperation and annexation and reorganization of motor and electric control enterprises.

The state regulates and controls some important raw materials of the motor, so that its price continues to rise several times. At the same time, the corresponding costs of R & D, production management and human resources in the enterprise are constantly improving, resulting in difficulty in improving the quality, quality and profit margins of the motor manufacturing enterprises. Therefore, the motor manufacturing enterprises in the sewing machinery industry should rely on improving scientific cost control to ensure reasonable profit margins while improving the quality of their products.

The author believes that the success of an enterprise does not represent an industry's progress. The driving force of the development of enterprises is not from decision making but from competitors. Mechatronics technology must really be at the forefront of the development of history, not forget the heavy burden of the development of the industry, through the construction of technology development platform, and form a comprehensive situation of technology sharing, leading the sewing machinery industry to achieve comprehensive pformation and upgrading.
