The high-speed positioning with an error of less than 0.005mm for 1000 times a minute, the movement of the completely independent action mechanism has been consistent and coordinated, Brush Machine efficient and highly intelligent equipment, the successful application of the universal CNC control system on the toothbrush tufting machine is called pride in the industry.
Toothbrush tufting machinery is roughly divided into three types: the first is a low-speed intelligent tufting machine developed by a single-chip system that drives a stepper motor (high degree of intelligence, but the speed is lower than the maximum 240 holes / min), and the second is high-speed Cam tufting machine,Brush Machine but the replacement variety must be made in accordance with the pre-designed trajectory to make a total of 3 types of cam discs and color change discs (processing cycle is long, the process is complicated, and can only be fixed varieties and colors).
The third type is a dedicated intelligent high-speed tufting machine system (strong specificity, expensive equipment and spare parts).
The key problem of system design: the general CNC system configuration is determined. Since our company has developed high-speed cam machinery, familiarity with equipment and action principles and combined with the company's own automation control technology level, we confirm the use of general CNC system with high-performance The servo drive equipment can meet the control requirements of the intelligent high-speed tufting machine, coupled with the stability and reliability of the general-purpose CNC system and anti-interference, it can fully meet the process requirements.
Before the configuration is determined, we detailed the technical requirements of the high-speed tufting machine on the system: high-speed and high-precision positioning requirements of 1000 times for 2 axes and half a minute, each positioning action including acceleration and deceleration time does not exceed 48MS; positioning accuracy error It should be less than 0.005MM; up to 4 kinds of output signals can be judged during the positioning process without delay output, Brush Machine and the logic can be quickly stopped. When the spindle frequency converter motor fails, it can stop from 1000RPM at most and not more than 2 revolutions, which is twice the speed of the mechanical brake. Fast response of detection elements (> 5000HZ). Reliability, stability and operation versatility of the system
The best combination of the stability and reliability of the universal CNC system and the high-speed response servo drive equipment is applied to the toothbrush tufting machine, which increases the production speed of the original single-chip microcomputer by nearly 3 times,Brush Machine and fully improves the production efficiency. The consistency and integration of system support will make the advantages of the system gradually manifest.
