1. Overview of computer flat knitting machine preselection system
The computer flat knitting machine preselection system is the core of the intelligent flat knitting machine. It combines electronic technology, computer programming and mechanical transmission technology, and can accurately select and control the knitting needles according to the preset program instructions. This system not only greatly improves the knitting efficiency, but also gives unprecedented freedom to fabric design, making it easy to achieve patterns from simple plain and twill to complex jacquard and intarsia.
2. The secret of needle selection operation
In each knitting cycle, the pre-selected system computerized flat knitting machine will perform multiple needle selection operations. This process is the key to fabric formation. The needle selector, as the "brain and hand" of the system, plays a vital role. It identifies and selects the specific knitting needles that need to be involved in knitting according to the instructions in the program. This selection process is based on complex algorithms to ensure the accuracy of the knitting needle movement.
Program instructions: Before knitting, the designer designs the pattern through software and converts it into program instructions that the computer flat knitting machine can recognize. These instructions record in detail which needles in each row and column need to move, and what actions to perform (such as knitting, tucking, transferring or joining).
Execution by the needle selector: During the knitting process, the needle selector selects the corresponding needle quickly and accurately by electromagnetic or mechanical means according to the instructions. The selected needle will receive an activation signal and prepare for the next action.
3. Motion control of knitting needles
The selected needles start to perform knitting actions under the drive of the triangle system. The triangle system is a series of carefully designed cams and sliders that move along a preset trajectory to guide the needles to complete different knitting actions:
Knitting: The needles pass through the yarn to form new loops and build the basic structure of the fabric.
Tucking: The needles only pull up the old loops without forming new loops, which is often used to create elasticity or special textures.
Transferring: Transferring one or more loops from one needle to another to form a pattern or change the fabric structure.
Joining: Connecting yarns of different colors or materials together to achieve color changes or material splicing.
The unselected needles remain in place and do not participate in the current knitting cycle. This mechanism ensures the clarity of the pattern and the structural integrity of the fabric.
4. Intelligence and flexibility
The introduction of the computer flat knitting machine preselection system not only improves the accuracy of knitting, but also greatly enhances the flexibility of production. Designers can adjust the design in real time, respond quickly to market demand, and realize a small batch and multi-variety production mode. In addition, through continuous optimization of algorithms and upgrading of hardware, computer flat knitting machines are developing in a more intelligent and automated direction, such as integrating AI-assisted design, remote monitoring and maintenance, etc., which further promotes the digital transformation of the textile industry.
