Research On CXWJ1280 Rapier Loom Weaving Machine

Song Yuxia has been engaged in the research of wide and heavy rapier looms for many years.

It is responsible for the electrical design of the project, which is responsible for the development of the electrical control system and guide the manufacture, installation and commissioning of the equipment.

The CXWJ1280 rapier forming net loom has a width of 12.8 meters. It can be used to weave the top grade multi-layer forming net with polyester monofilament as well as other polyester nets and industrial nets. The width and quality of the looms can fully meet the needs of wide and high-speed paper machines and replace imports.

The machine integrates the technology of machine, electricity, gas, liquid and light, has high technical content, and has independent innovation. It solves the problem of weft insertion and opening of super wide loom, and solves the problem of weft insertion and reed weft interference caused by ultra wide width. It has a high cost performance ratio.

The equipment has made breakthroughs in electrical control, which has greatly improved the efficiency and performance of the equipment.

Main innovation points of the project

1. using servo

To solve the problem of weft insertion in super wide rapier, a servo motor with high resolution feedback encoder is used to directly drive the pmission wheel with a circumference of 1m, and a complete weft insertion is achieved.

2. the active opening multi arm (multiple arm) controlled by the cylinder is used to solve the problem of ultra wide opening.

3. solve the problem of super wide by improving the main motor.

The contradiction between the operation of the belt and the beating up of the reed.

The CXWJ1280 rapier loom has sold 21 units from 2012 to March 2014.

Sales revenue of about 78 million yuan, the profit of about 37000000 yuan.

The main customers are: Anhui Ya Dong Jinlong net Industry Co., Ltd., Anhui Huafeng net Industry Co., Ltd. and other more than 10 enterprises.

After using it, we can successfully produce a qualified finished product net which meets the requirements of various companies. The economic and social benefits are remarkable.

In view of the problem of insufficient mechanical properties of polysulfonamide (PSA) fibers developed by our country, Zhang Yumei is one of the main participants in the project. She and his team members used synchrotron radiation technology to establish a multilevel and multi-scale quantitative analysis method for analyzing the fiber from molecular structure to microstructure. Based on the analysis results of non-equilibrium structure in fiber forming process, the structural factors restricting the mechanical properties of fibers were excavated, and the relationship between fiber structure properties and process was established, which is the basis of new process design and effectively improves the mechanical properties of fibers.

Main innovation points of the project

1. the interaction between molecules is illustrated by means of synchrotron radiation X- ray diffraction and molecular simulation. It provides a basis for the quantitative calculation of supramolecular structure of polysulfonamide fibers.

2. the synchrotron radiation technology was used to study the evolution of morphology and structure during the spinning process of PSA, indicating the technological conditions of the pition point of PSA crystal structure and the lamellar structure formed along the spinning process, which effectively improved the mechanical properties of the fibers.

3. an on-line detection method for the microstructure of polysulfonamide fiber during the forming process was established.

The results of the project were applied to the 1000 ton production line of Shanghai teunlun Fiber Co., Ltd., and produced 15 tons of 1.5D and other standard fibers. From the application effect, the tensile strength of the fibers was greatly improved and the average strength of the tested batches reached 3.5~3.7cN/dtex. The mechanical properties of the original fibers were improved, and the curling effect was optimized.
