The HV-GM200 intelligent online grammage meter is a major breakthrough in fabric grammage detection! Changzhou Hongda Intelligence Technology Co., Ltd. (hereinafter referred to as "Changzhou Hongda") After just a few months, the independently developed HV-GM200 intelligent online grammage meter, Zhejiang Seven Rainbow Holdings Group Co., Ltd. (hereinafter referred to as "Seven Rainbow Group") Production Supervisor Dai Yuanxiong gave such high praise.

Seven Rainbow Group is a leading enterprise in the segmented market of knitted fabrics (natural degradable and renewable fiber knitted fabrics), and is also one of the top 20 knitting enterprises in China. The group's products are sold under the independent brand "Seven Rainbow SIRIS", and are sold well in the domestic market and exported to European and American markets. It has also established long-term cooperation with well-known brands such as Nike, CK, KOHL'S, M&S, and DKNY.

In the constantly iterating and upgrading textile fabric market, Seven Rainbow Group uses innovation to open up the market. Behind its success as a globally renowned fabric supplier, it is inseparable from the support of advanced equipment enterprises, and Changzhou Hongda is one of them.

Seven Rainbow Group is a pioneer in the implementation of green development among domestic printing and dyeing enterprises. In order to quickly improve the intelligent level of enterprise production control, improve product quality, increase the first-pass yield, and achieve energy saving and consumption reduction, Seven Rainbow Group took the lead in introducing the HV-GM200 intelligent online grammage meter independently developed by Changzhou Hongda.

"Changzhou Hongda has a professional R&D team with skilled technology and rich experience. They have a strong sensitivity and foresight to the technological development trends of the industry at home and abroad, and they can accurately grasp market demand, and the products they develop can meet the pain points of users. Every time they launch a new product, we are willing to try it, especially the world's first HV-GM200 intelligent online grammage meter with multiple intellectual property rights." Dai Yuanxiong told a reporter from China Textile Daily.

According to Ge Zhaoyu, head of the R&D department of Changzhou Hongda introduction, intelligent online grammage meters are usually installed after the cloth shears of the setting machine to measure the fabric width and grammage online before the cloth falls.

Speaking of the initial intention of developing the HV-GM200 intelligent online grammage meter, Ge Zhaoyu said that the heat setting process is an important link in the post-finishing process of textile dyeing and finishing, and the fabric grammage and width are important indicators to measure whether the product is qualified in the heat setting process. For a long time, the measurement and control of grammage and width in the heat setting process have been carried out manually, and it is impossible to understand the fabric grammage and width in the continuous production process in real time. At the same time, manual weighing with a scale will damage the textile products, resulting in a low grammage qualification rate, unstable product quality, and waste of finished products.

The HV-GM200 intelligent online grammage meter independently developed by Changzhou Hongda adopts high-precision micro-force measurement technology constructed from new aviation materials, which can measure the fabric grammage online in real time during operation. The servo motor and driver used in the system control the measurement range, and can also ensure the stability and measurement accuracy of the product. "We not only want to meet the explicit needs of customers, but also want to be ahead of customers and stimulate the hidden needs of customers. This is the main reason why we never feel confused about our technology landing and product positioning." Ge Zhaoyu said.

Dai Yuanxiong said that after recent use, the comprehensive advantages of the HV-GM200 intelligent online grammage meter are very obvious: replacing manual labor, improving the intelligent level of enterprise production, improving the quality of company products, greatly reducing fabric loss in the production process, helping enterprises reduce production costs, and improving the economic benefits and core competitiveness of enterprises.

Before introducing the HV-GM200 intelligent online grammage meter, Seven Rainbow measured fabric grammage using manual offline scale weighing.

Dai Yuanxiong frankly admitted that in actual production, this traditional weighing method cannot accurately measure the actual weight of the fabric. Dai Yuanxiong told a reporter from China Textile Daily that to calculate the grammage, employees need to manually measure three points on the left, middle, and right of the fabric, and then manually calculate the current fabric grammage. This indirect weighing method can only take local samples, not only has poor real-time performance, but also affects the product qualification rate, cannot guarantee the stability of product quality, and the loss of fabric due to scaling is also huge. After installing the HV-GM200 intelligent online grammage meter, real-time online measurement of fabric grammage during production can be realized. In the production workshop, Dai Yuanxiong cut three pieces of cloth from the running setting machine for scaling, and the average grammage of the fabric was about 222g/㎡. The same fabric was measured by the HV-GM200 intelligent online grammage meter, and the grammage was 223g/㎡, with a difference of only 1g per square meter, the high precision is amazing.

In recent months, Ge Zhaoyu has been in the production workshop of Seven Rainbow Group, providing technical guidance on the installation and debugging of the HV-GM200 intelligent online grammage meter. According to the characteristics of the fabrics recently produced by Seven Rainbow Group, Ge Zhaoyu guided the company's employees to enter four sets of production indicators in the system in advance, so that when producing related products, they can directly retrieve the system data, which is very convenient and fast.

"I must give a thumbs up to Changzhou Hongda's after-sales service!" Dai Yuanxiong said with a smile. In addition to excellent product quality, good service reputation is another shining business card of Changzhou Hongda, which is also an important reason why Changzhou Hongda has won in the fierce market competition. In terms of product quality and technological innovation, Changzhou Hongda has built a unique "intelligent setting machine intelligent system" based on artificial intelligence technology, relying on advanced business management concepts, a professional after-sales service team, and products with core competitive advantages, Changzhou Hongda has the strength to provide a solid equipment foundation for the high-quality development of printing and dyeing enterprises.

Since purchasing the first equipment from Changzhou Hongda, the technical personnel of Seven Rainbow Group have maintained a 24-hour contact status with the technical engineers of Changzhou Hongda. Changzhou Hongda technical engineers will also regularly visit the company to record the operation of the equipment in detail, and will quickly solve the problems raised by the company's employees. "In addition to using the HV-GM200 intelligent online grammage meter and density detection overfeeding system, we also use multiple sets of Changzhou Hongda whole flower and whole weft machines. Over the years, the core components of the equipment have not had any problems, and the failure rate of small accessories is also low. Whenever any problem occurs, as long as one phone call, Changzhou Hongda staff will arrive on-site for service in the shortest time. Compared with multinational companies and other equipment suppliers, Changzhou Hongda's service is very touching." Dai Yuanxiong recalled.

Market demand is the foundation of a company's survival, and customer satisfaction is the driving force of its development. Like Changzhou Hongda, the Seven Rainbow Group has been constantly striving to build itself into a responsible, accountable, and distinctive excellent enterprise, tirelessly promoting technological innovation and service improvement in order to better repay the trust and support of its client companies. Dai Yuanxiong stated that the Seven Rainbow Group will continue to improve its practical and effective mechanisms for technological innovation and customer service, fully mobilizing the enthusiasm, initiative, and creativity of personnel in various positions within the company to achieve another leap in the company's development.
