Features

1. The suction, metering and mixing devices adopt frequency conversion control, which is accurate and reliable; the material level exceeds the limit and automatically alarms.

2, screw extruder adopts high-precision helical gear reducer. The extruder has the characteristics of high precision, high reliability, high safety performance and long service life by adopting three-closed loop control.

3. The solution pipeline adopts the form of electric heating and is wrapped with insulation materials. It has the characteristics of short solution flow and automatic control of heating and insulation.

4. The spinning die head is an integral slit structure with a special melt distribution cavity for uniform melt distribution. Adopt integral spray plate to make tow distribute evenly.

5. The lateral blower adopts double-sided symmetrical blowing structure, and there are multi-layer rectifying devices in the air duct.

6. The drafting air duct adopts slit type to draft the tow. Lower draft air duct, diffusion air duct, adjustable width.

7. The net laying machine consists of main drive, net curtain, frame, suction air duct, correction device, tension device and other parts.

8, suction and diffusion air duct in the brush and sealing roller under the action of isolation from the environment, forming a separate control to adapt to different process requirements.

9, advanced automatic control. The whole production line adopts industrial control computer to monitor and manage the whole process flow. PLC control of the entire production line. Profibus technology field bus is used to communicate with various frequency converters such as screw extruder, spinning machine, net laying machine, hot rolling mill and winding machine of the production line, and communicate with temperature control module of the production line through communication board.

10, can display the flow diagram of the equipment, the main process parameters (screw temperature, melt pipe temperature, die zone temperature, metering pump speed, web laying machine speed, hot mill speed, spunbond system used air conditioning process parameters, meltblown spinning system used hot air system equipment spinning process parameters, etc.) set values and measured values and alarm values of each control point. It can display trend charts of process history books and print process history data.

11, PP spunbonded nonwoven fabric production line adopts single hanger die technology and proprietary cooling blowing rectification system, combined with advanced airflow drafting technology and high-speed web forming technology, coupled with digital control system, so that the product uniformity is good, fineness is fine, vertical and horizontal strength is high, low energy consumption. The overall performance of the production line has reached the advanced technical level of similar foreign equipment.
