The quality assurance of high speed tricot warp knitting machine is a systematic project involving multiple key links.
1. Precision equipment design and manufacturing
First of all, equipment design is the foundation. Advanced design concepts ensure that the structure of the warp knitting machine is reasonable. For example, the number of combs and the layout of the needle bed are reasonably planned to meet the weaving needs of different fabrics. In the manufacturing process, strict tolerance control is the key. The processing accuracy of parts must meet extremely high standards. The dimensional errors of key parts such as needle bars and sinkers must be controlled within a very small range to ensure their matching accuracy at high speeds and reduce weaving defects caused by mechanical precision problems. At the same time, high-quality metal materials and wear-resistant coatings are used to enhance the wear resistance and corrosion resistance of parts, extend the service life of the equipment, and thus stabilize product quality.
2. Accurate process parameter control
In the warping process, the warp tension and arrangement density must be accurately controlled. Uneven tension will cause the fabric to be unevenly tight, so a high-precision tension adjustment device is required. During the weaving process, parameters such as the warp feed amount, pulling speed, and needle bed movement speed must be accurately matched. According to the fabric structure and density requirements, the parameters are adjusted in real time through the computer control system to ensure that each coil is formed accurately. Moreover, for warp yarns of different materials, such as polyester fiber, spandex, etc., the process parameters should be adjusted in a targeted manner to adapt to their physical properties.
3. Strict equipment maintenance and care
During daily maintenance, regularly clean the flying flowers and dust inside the equipment to prevent them from entering the mechanical transmission parts and affecting the accuracy. The lubrication system should be strictly managed, and high-quality lubricating oil should be added according to the prescribed time and amount to reduce the wear of machine parts. Regularly check the wear of parts such as needle beds and combs, and replace severely worn parts in time. In addition, establish an equipment failure early warning mechanism, monitor the equipment operation status through sensors, and warn and handle possible failures in advance to avoid product quality degradation due to equipment failure.
4. Comprehensive quality inspection system
Install online inspection equipment on the production line to monitor the density of the fabric, whether there is yarn breakage, etc. in real time. Once a problem is found, stop the machine immediately for adjustment. In the finished product inspection phase, the appearance quality and physical properties of the fabric are comprehensively tested, including checking whether there are defects on the surface of the fabric, measuring the tensile strength and shrinkage of the fabric, etc., to ensure that the product quality meets the standards.
