Taifenglai high-speed tufting machine has a promising market

In modern society, teeth have become a symbol of health and beauty, and the demand for toothbrushes is gradually increasing. At present, the global annual demand for toothbrushes has exceeded 9 billion, and it is increasing at an annual rate of 10%. With a large population in China, toothbrushes are in great demand as a necessity for modern life. Although the toothbrush is small, it is a mature commodity with a huge consumption market. With the improvement of the quality of life, the quality of toothbrushes has also improved. The production efficiency and production quality requirements of high-quality health toothbrush equipment promote the development of high-speed toothbrush hair transplanting machines. . The toothbrush output of Hangji Industrial Park, the China Toothbrush City in Yangzhou, Jiangsu Province, accounts for 80% of China's toothbrush output, with an annual output of 3 billion pieces. Manufacturers of toothbrush equipment used to use the same brand of single-chip control system and servo motor electric control system in the past, and most of the servo systems are imported from Japan. In recent years, the servo products of Taifenglai high-speed tufting machine have been increasing in the high-speed toothbrush tufting machine industry due to their excellent performance and competitive price advantage. Brief description of the principle of toothbrush tufting machine The transmission structure of the high-speed toothbrush tufting machine consists of a main drive shaft and four servo drive shaft systems. The four servo axes are the horizontal X axis, the vertical Y axis, the flap Z axis and the hair changing U axis. The XY two-axis coordinates determine the position of the toothbrush hole, the Z-axis plays the role of changing to the next toothbrush, and the U-axis plays the role of changing the toothbrush hair color. When the spindle motor is running, the four electronically controlled servo axes will follow-up and the remaining four axes will follow-up and stop when the spindle stops. The rotation speed of the main shaft determines the speed of planting hair, and the four servo axes respond to the coordinated drive, otherwise there will be hair loss or uneven hair. Using Delta's high-precision electrical servo control can achieve 1,000 times per minute hair transplanting speed, and can achieve jump-hole hair transplanting. At present, the structure of the hair planting electrical control system is mainly divided into a single-chip control system or a CNC numerical control system. Among them, the single-chip control system is based on the integrated supporting services of the automation system manufacturer, and the independent research and development of the toothbrush equipment manufacturer is supplemented. The CNC numerical control systems with superior performance are mostly imported brands such as Delta's PUTNC-H2P and Europe and Japan. CNC numerical control mainly controls the axis pulse command signal to achieve servo drive, usually four-axis control output. Delta's CNC only needs two-axis output to achieve it. The other two axes of Zhongda's servo can be completed independently. Toothbrush tufting machine requires system It can realize two-axis interpolation operation. The four sets of servo drive models are Taifenglai's high-speed tufting machine series, with a power of 400W, and the drive has multiple function controls. The spindle motor inverter model is Zhongda's VFD-S, with a power of 400W. Debugging points The difficulty in the development of a servo solution is the joint debugging of the electromechanical system, which is mainly the adjustment of the servo gain. Among the four servo axes, X-axis and Y-axis are relatively stable due to the mechanical inertia of the screw drive structure, and debugging is relatively easy, and the bandwidth can generally be adjusted to more than 130HZ. The Z-axis of the flap is a rotating axis. High-speed rotation has centrifugal force. If the bandwidth is simply set high, the motor will vibrate when it starts and stops. At this time, the position smoothing filter parameter can be turned on to eliminate vibration. Relatively speaking, the mechanical structure of the cam mechanism of the U-axis for hair removal makes debugging difficult. In addition, the mechanical rigidity of the U-axis is not good. When the motor is running, the inertia ratio changes greatly, and the motor output current changes greatly, so the parameters cannot be adjusted. Well, when the motor is running from side to side, the shaft either vibrates or screams, or reacts slowly. For this, it is necessary to apply the resonance suppression function of the B series ASDA-B AC servo system.
