INVT provides one-stop solutions for non-woven fabric production

Create Date: 2024-8-30 12:03:23|Source: INVT/INVT

The basic principle of the non-woven fabric process is to use the ribbed with a triangular section (or other cross-section) edge and barb to repeatedly puncture the web. When the barb passes through the web, the surface of the web and part of the inner layer of fibers are forced to pierce into the web. Due to the friction between the fibers, the otherwise loose web is tightened. When the needle exits the web, the penetrated fiber bundles break away from the barb and remain in the web, so that many of the fiber bundles become entangled in the web and can no longer be restored to its original loose state.
INVT provides one-stop solutions for non-woven fabric production

After many times of acupuncture, a considerable number of fiber bundles are pierced into the web, so that the fibers in the web are entangled with each other, so as to constitute a certain strength and thickness of acupuncture non-woven materials, products such as: geotextiles, geomembranes, halberd flannel cloth, speaker blankets, electric blanket cotton, embroidery cotton, clothing cotton, Christmas handicrafts, human leather base cloth, filter data special cloth and other products.

Urgent customer urgency, concentrate skills and strength to tackle key problems

According to the specific needs of customers, the technical team proposes targeted solutions, and the electrical part mainly includes IVC1L series PLC, VS series touch screen, and GD series inverter. Through real-time communication between PLC and inverter modbus, and set or display the speed, acceleration and deceleration and other parameters of the motor in the HMI, and adjust the speed of each motor in real time according to the processing technology and raw material weight and other factor parameters. Moreover, the communication rate between PLC and inverter is required to be stable, and the feeding and weighing part also requires precision control within ±10g, which has the function of self-leveling.

System planning features

The processing parameters can be adjusted in real time by HMI, which is easy to operate;

The plan is divided into long-distance control or local control methods (two sets of PLC systems);

Through active weighing, the supply speed of raw materials is controlled to achieve uniform feeding;

The PLC controls the inverter through Modbus communication to adjust the speed of the equipment in real time;

It has the function of metal detection, if the raw material is mixed with metal, it can take the initiative to alarm and stop the feeding;

When the inverter or field sensor fails, the system will actively alarm/maintain/shut down.
