High speed warp knitting machine HKS3 successfully achieved 2500 RPM operation technical report

With the increasing demand for efficient production equipment in the textile industry, the research and development of high-speed warp knitting machines has become the key to improving productivity and competitiveness. HKS3 high-speed warp knitting machine is developed by our technical team, the goal is to break through the speed bottleneck of traditional warp knitting machine and achieve efficient operation of 2500 RPM under the premise of ensuring stable fabric quality.

Test equipment parameter

- Model: HKS3-MT2500

- Width of needle bed: 130 inches

- Drive system: servo motor direct drive

- Control system: intelligent dynamic balance algorithm

Test process

- Stage 1: Gradually increase the speed to 2000 RPM for 8 hours to monitor equipment vibration, temperature and fabric uniformity.

- Stage 2: Optimize the dynamic balance of the needle bed and yarn tension control, and increase the speed in stages to 2300 RPM and 2400 RPM.

- Stage 3: The application of new shock-absorbing materials and high-speed yarn guide mechanism, the final stable operation at 2500 RPM, continuous production for 24 hours without trouble.

Test results and analysis

1. Key performance ind

icators

- Speed: 2500 RPM (industry average 1800-2200 RPM)

- Production efficiency: 36% higher than the previous generation model, single machine daily output of 4500 meters (g weight 120g/㎡ fabric).

- Quality stability: defects rate ≤0.3%, fabric density deviation control within ±1.5%.

- Energy consumption performance: Energy consumption per unit output is reduced by 18%, reaching the national energy efficiency standard.

2. Technological breakthrough

- Mechanical structure optimization: The use of carbon fiber reinforced needle bed and lightweight connecting rod mechanism to reduce inertia resistance.

- Intelligent control system: real-time monitoring of yarn tension fluctuations, dynamic adjustment of the warp let off, avoid yarn break.

- Vibration suppression technology: Active shock absorption system based on multi-sensor fusion reduces the amplitude of the device to less than 0.05mm.

Validation data

HKS3 high-speed warp knitting machine successfully broke through the technical barrier of 2500 RPM, marking that domestic high-speed warp knitting machine ranks among the international advanced ranks. Next step:

1. Carry out the adaptability test of multi-material yarns (such as ultra-fine silk and elastic fiber);

2. Promote intelligent upgrade, integrate AI defect detection and predictive maintenance functions;

3. Target mass production by 2024 to help textile enterprises reduce costs and increase efficiency.
