On April 10, 2018, the 8th National Knitting Technology Conference hosted by China Knitting Industry Association was held in Haining, Zhejiang. Mr. Gu Ren, Chairman of Changzhou Hongda Technology (Group) was invited to attend the meeting and made a topic entitled "HawkVision Knitting". Report on the Industrial Application of Intelligent Image Whole Flower Technology. In the report, Mr. Gu introduced the technical research and product application of Changzhou Hongda in knitting intelligence in recent years, especially in the production process of wall coverings and curtains faced by enterprises in Haining area, which is urgently needed to solve the correction technology and products of flower shape. The problem provided detailed solutions and related product recommendations. Finally, I shared with you the successful application of relevant local enterprises, which aroused the enthusiastic response from the participants and received the eager attention of the local participating companies!

Solve the problem of flower shape deformation of knitted fabric

Focus on the flower shape quality of knitted fabrics

Knitted fabrics are prone to flower-shaped deformation during processing and finishing due to their loose weaving, strong permeability and high flexibility. For example, in the process of washing and knit cloth in the process of washing, the jacquard knitted fabric is prone to flower deformation, especially the geometric pattern is particularly obvious, which seriously affects the success rate of production and product quality, resulting in quality complaints and disputes.

Hawk Vision intelligent image whole flower weft knitting machine is the "HockVision" brand relying on its strong European technical background and Changzhou's profound technical research and development strength, the first international leading "full-width scanning whole-flower latitude technology", full-width scanning more than 8000 The monitoring point completely solves the problem of flower shape deformation, weft inclination and weft bending of the knitted fabric which cannot be corrected and recognized by the photoelectric whole weft, and surpasses the value of photoelectric weft and ordinary image weft. The technology has reached the international leading level through the appraisal of the China National Textile and Apparel Council, and won the first prize of the “Textile Light” 2017 China Textile Association Science and Technology Progress Award.

HawkVision intelligent image whole flower weft knitting machine has a wide variety of adaptability, in addition to all varieties suitable for photoelectric weft, it also adapts to many varieties that can not be properly identified and corrected by photoelectric weft, such as: jacquard knitted fabric, printed knitted fabric, heavy Knitted fabrics, sanded knitted fabrics and complex weave knitted fabrics have greatly improved the finishing quality of knitted fabrics.

Knitting printing block online detection

In the process of knitting printing, white spots (missing) and color points (staining) are often formed periodically on the cloth due to the reason of the printing net head or the dye or the net head staining. Since the printing machine can not be stopped frequently during the process, some defects will occur continuously and periodically in the same position once, resulting in continuous waste. Compared to some random black spots and ink dots, continuous waste in the printing process will have a greater impact on the quality of the entire batch of cloth.

The inspection system is installed on the printing machine to perform 100% quality monitoring on the cloth. When the cloth is found, the machine can be alerted in time to remind the workers to adjust the printing machine to improve the product quality. The system adopts machine vision image processing technology, which can realize automatic detection and alarm of blocking network during printing process, and continuously detect printing quality in real time online. The whole process is continuous real-time detection with less manual intervention. It can greatly reduce the skill requirements and labor intensity of operators, and improve the yield of products. It is an essential product for medium and high-grade knitted printed fabrics.

Fixing machine automatic overfeed control system

Due to the weave and material, the knitted fabric is easy to be stretched and narrowed during the finishing process. Therefore, in order to ensure the stability of the quality and size of the knitted fabric, the density in the shaping process of the fabric must be automatic. control. The ultra-feeding control system of the shaping machine adopts intelligent image technology to monitor the weft density of the fabric on the cloth side during the shaping process. When the weft density of the fabric cannot reach the set value, the weft density is adjusted to the ideal state in real time through the overfeed adjustment system. In order to ensure the uniformity of the weft density, the quality of the knitted fabric per unit area can be achieved, and the success rate can be improved to ensure high-quality textiles.

The “green production and intelligent manufacturing” promoted by the conference is both the trend and the right time. With its own advantages over the development and development of textile printing and dyeing digital technology for nearly 30 years, Changzhou Hongda will always rely on technology to provide support for the intelligent printing equipment of the textile printing and dyeing industry, and fully assist the knitting industry to promote “green production and intelligent manufacturing”. Leading the development of automation, intelligence and digitalization of the textile printing and dyeing industry.
