In the modern textile industry, computerized flat knitting machine has become an indispensable and important equipment for knitting production with its high efficiency, flexibility and precision. Its core lies in a highly intelligent control system, which can realize complex and changeable knitting structures through a series of precise operations according to the preset knitting pattern and process requirements. This article will deeply explore the mechanism of signal transmission and recognition in the control system of computerized flat knitting machine, as well as how the needle selection cutter head can achieve precise movement, and jointly support the efficiency and precision of the entire knitting process.
Signal transmission and recognition: intelligent transmission of knitting instructions
The control system of computerized flat knitting machine is the brain of the entire knitting process. It is responsible for converting the designer's creativity and the requirements of the craftsman into specific knitting instructions. These instructions exist in the form of control signals, which are accurately transmitted to various key components of the machine through a complex circuit network, the most important of which is the needle selector.
The signal transmission process is a highly accurate and fast process. The control system first calculates when and how each knitting needle moves based on the input pattern data and process parameters. These action instructions are encoded into electrical signals and transmitted to the needle selector at the speed of light through integrated circuit boards and wires. In this process, the stability and accuracy of the signal are crucial, and any slight interference or error may lead to deviations in the knitting results.
As the terminal that receives and executes these signals, the internal design of the needle selector is also complex and delicate. It can not only quickly identify the electrical signals from the control system, but also accurately control the needle selector at the corresponding position to perform lifting and lowering actions according to the different signals. This ability to identify and respond is the basis for the computerized flat knitting machine to achieve complex pattern knitting.
Precise movement of the needle selector head: microscopic display of knitting art
If the control system is the intelligent center of the computerized flat knitting machine, then the needle selector head is the "hand" that performs precision knitting tasks. Each needle selector head is a high-precision component that has been carefully designed and manufactured. Their swing angle, strength and motion trajectory have been strictly calculated and tested to ensure that they can maintain extremely high accuracy and stability even in high-speed operation.
The swing angle of the needle selector head is directly related to whether the needle selector can be accurately lifted, which in turn affects the threading and knitting effect of the yarn. Too large an angle may cause excessive wear or damage to the needle selector, while too small an angle may not effectively lift the needle selector, resulting in missed or wrong needles. Therefore, the swing angle of each cutter head is determined based on the needle specifications, yarn type, and knitting process.
Strength control is also critical. The needle selector head needs to exert a certain amount of force when it moves to overcome the static friction of the needle selector and lift it. But this force must be just right, to ensure the smooth progress of the needle selection action and to avoid unnecessary damage to the needles and yarn. To this end, the design team of the computerized flat knitting machine usually uses advanced materials and manufacturing processes, as well as precise mechanical analysis, to ensure that the action force of each needle selector head is optimal.
In addition, the number of needle selector heads is also reasonably configured according to the number of needles and knitting requirements. In areas with large knitting widths or complex patterns, more needle selector heads are required to cope with higher action frequency and precision requirements. This flexible configuration method enables the computerized flat knitting machine to adapt to a variety of different knitting tasks, from simple plain weaves and twills to complex jacquards and intarsias, which can be completed with ease.
