1. Large opening and oblique opening, simple and solid structure, driven by a balanced movable rocker arm, suitable for high-speed operation. 2. The moving stroke is small, the driving components are balanced, the running vibration is small, and the number of transmission components is minimized. 3. The bearing design is precise and the surface is strictly treated, with minimal wear. 4. Easy loading and unloading, convenient for users to operate. 5. Integrated solenoid valve configuration, small size, flexible movement during operation. 1. The main motor and electronic weft density motor adopt the current international advanced servo motor, which is characterized by high point power and torque 1.5 times larger than that of conventional two-speed motors, which greatly reduces the failure repair rate of conventional two-speed motors. 2. Save electricity and reduce electricity consumption by 30%. 3. The electronic weft density is driven by the most advanced servo motor in the world and a high-precision planetary deceleration head. The belt pulling force is strong, anti-retrogression, and the belt surface is smooth and even. It is controlled by the computer system. It can adjust the weft density range more accurately and change the weft density. Convenient, rabbit refueling, maintenance-free. 4. The control system is equipped with a built-in programmable and data system, which can record and display various production data, and automatically display faults and causes. In case of special circumstances, the data can be backed up in a timely manner
