INVT GD350 Inverter for Stenter Setting Machine

1. Introduction

As a pillar industry of the national economy and a livelihood industry, the textile industry has further improved production efficiency by transforming from early manual production to mechanized production. However, driven by the continuous advancement of science and technology and innovation, various new materials and technologies are constantly emerging. On the basis of improving the manufacturing quality and reliability of equipment, textile machinery also needs to achieve automation and continuous production.

During the scouring, bleaching and dyeing process, the fabric is stretched in the warp direction and contracted in the weft direction due to many mechanical tensions in the warp direction, resulting in uneven width, uneven cloth edges, skewed wefts, etc. In addition, the old-fashioned stenter setting machine has a slow speed and low automation, which cannot keep up with the production demand. In order to overcome the above shortcomings, a textile enterprise is looking for a new system solution to transform and upgrade the stenter setting machine to realize the fully automatic stenter setting function of the fabric.

2. INVT solution

In order to achieve a high degree of automation and improve production efficiency, INVT launched the HMI+PLC+GD350 VFD system solution, which uses high-speed industrial bus communication. The PLC and GD350 are connected by a network cable to form a network. The unformed cloth is fed into the machine by the edge stripper, and then passes through several constant temperature ovens with different temperature ranges. After being stretched and formed at the tail end, it is wound on a specific winding mechanism. The performance of the stenter setting machine is more stable during operation, which improves the equipment speed. The automation system greatly improves production efficiency and creates higher profit value.

3. Customer benefits

●INVT system solution can realize the automatic operation of the stenter setting with high process stability, which saves both labor and energy for operators.

●After the process recipe parameters are confirmed, they can be stored in the PLC for future use, review and modification.

●High flatness of finished winding products: The finished winding products are flat and wrinkle-free, and the needle plate is perfectly controlled when it is detached.

●Length/roll diameter setting: The winding length or roll diameter can be set, with early warning and full roll alarm prompt functions.

4. Conclusion

The stenter setting machine plays an irreplaceable and important role in textile finishing. After the INVT solution upgrade, it not only operates reliably and stably for a long time, but also improves efficiency and production capacity, enhancing the market competitiveness of customers.

As the world pays more attention to environmental protection, the textile industry also needs to shift to a sustainable development model. INVT will also adopt more environmentally friendly production processes and technologies to enable industry development and reduce pollution to the environment.
