In-depth analysis of the looping process of a double needle bed warp knitting machine

The looping process of a double needle bed warp knitting machine is a highly dynamic and precise process, which relies on the close cooperation of multiple mechanical parts such as the needle bed, comb bar and sinker bed. In a complete knitting cycle, the rotation of the main shaft drives these parts to move according to the predetermined timing and path, and together completes the key steps of yarn grabbing, pulling, closing, unhooking and looping. The accuracy and stability of this process directly determine the quality and production efficiency of the fabric.

The needle bed is one of the core components of the double needle bed warp knitting machine. It carries the needle hook and is responsible for completing the grabbing, pulling and closing of the yarn during the knitting process. The design of the needle bed not only requires the needle hook to have extremely high wear resistance and hardness, but also needs to ensure that the position and tension of the yarn can be accurately controlled during the knitting process. In addition, the structure and layout of the needle bed also directly affect the structure and appearance of the fabric, such as the size, tightness and pattern of the coil.

The guide bar is another important mechanical component in the double needle bed warp knitting machine. It is responsible for guiding the yarn to the needle hook and swinging and moving laterally during the knitting process. The movement trajectory and speed of the guide bar need to be precisely synchronized with the movement of the needle bed to ensure that the yarn is guided to the needle hook at the correct position and time. In addition, the swing and lateral movement of the guide bar need to be adjusted according to the knitting requirements to achieve different knitting effects and patterns.

The sinker bed plays a vital role in the looping process of the double needle bed warp knitting machine. The sinker is responsible for pressing the yarn under the needle hook before the needle hook closes to prevent the yarn from slipping during the knitting process. At the same time, the lifting and lowering action of the sinker also helps control the size and tightness of the loop, which in turn affects the quality and appearance of the final fabric. The precise control of the sinker bed requires the sinker to be able to rise and fall according to the predetermined timing and height to ensure that the yarn is fixed in the correct position and time.

The close cooperation between the needle bed, the comb bar and the sinker bed is not only reflected in the precise design and manufacture of the mechanical parts, but also in the precise control of the movement of each part by the control system.

In the mechanical design of the double needle bed warp knitting machine, the size, shape and material of each part need to be strictly calculated and tested to ensure that they can be precisely matched during the knitting process. For example, the spacing between the needle bed and the comb bar, the shape and size of the needle hook, the lifting height of the sinker, etc. need to be precisely controlled to ensure that the yarn can move according to the predetermined path and speed during the knitting process. In addition, the wear resistance, hardness and fatigue resistance of the mechanical parts also need to be strictly tested and evaluated to ensure that they can remain stable and reliable during long-term high-speed operation.

In the control system of the double needle bed warp knitting machine, advanced electronic technology and sensor technology are usually used to precisely control the movement of each part. The control system receives signals from the sensor, monitors the parameters such as the position, speed and acceleration of each part in real time, and precisely adjusts the movement of each part according to the preset knitting program and parameters. This precise control not only ensures the close cooperation between the various parts, but also improves the knitting efficiency and fabric quality.

With the development of intelligent technology, the control system of double needle bed warp knitting machines is also constantly innovating and upgrading. For example, by introducing artificial intelligence and machine learning technology, the control system can automatically identify and optimize the parameters and procedures in the weaving process to improve weaving efficiency and fabric quality. At the same time, intelligent technology can also realize functions such as remote monitoring and fault diagnosis, providing a more convenient and efficient solution for the operation and maintenance of double needle bed warp knitting machines.

The looping process of the double needle bed warp knitting machine is a highly dynamic and precise process, which relies on the close cooperation of multiple mechanical parts such as the needle bed, comb bar and sinker bed. This cooperation is not only reflected in the precise design and manufacturing of mechanical parts, but also in the precise control of the movement of each part by the control system. By continuously optimizing the mechanical design and control system, the double needle bed warp knitting machine can achieve higher weaving efficiency and fabric quality, meeting the market's diversified demand for high-quality textiles.
