The reasons for mechanical failures and fabric defects during high-speed braiding machines are relatively complex. In order to facilitate maintenance, based on practical experience, they can be roughly summarized into the following aspects:
- Poor maintenance work will cause serious wear and tear of parts during long-term operation.
- Due to the quality of raw materials.
- The doffing workers and turning workers are not skilled in their operations.
- Braiding machine parts (such as knitting needles, brushes, shuttle nozzles, etc.) are of poor quality and improperly adjusted.
- The product process is unreasonable, such as the selected yarn count and machine number are not suitable, etc.
High-speed braiding machines are favored by the majority of small and medium-sized enterprises and self-employed people due to their lightness, portability, multiple functions, and low prices, resulting in increasing sales of braiding machines in our country. Since many braiding machine users do not have a deep understanding of the structure and performance of the braiding machine, they are often troubled by some minor faults during use. Floating rings are one of the common ones. Floating loop means that at the beginning of loop formation, when the knitting needle rises to unloop, for some reason, the old loop does not retreat to the needle bar below the needle tongue, but still hangs on the needle tongue. When the knitting needle drops, the old loop coil returns to the needle hook and cannot form a new coil. This phenomenon is called a floating loop.
Computer-controlled automatic needle selection braiding machine. This type of braiding machine selects needles by a computer-controlled electromagnet mechanism. The needle selection system generally includes a pattern recognition system, a pattern storage system, a needle position determination system, etc. Computerized braiding machines are characterized by high knitting efficiency, full functions, good knitting quality, and a wide range of knitting patterns. Using a computer braiding machine can greatly improve the quality of knitted clothing.
The electromagnetic needle selection component mainly consists of a movable armature, a needle selection cylindrical coil, a cylindrical coil magnetic core, and some auxiliary parts. In addition to knitting all the patterns that pattern plate automatic needle selection braiding machines can knit, computer braiding machines can also knit many other patterns. In this regard, different models of computer braiding machines can achieve different functions.
It can be seen that the knitting capacity of this computerized braiding machine is greatly improved compared to the plate-type automatic needle selection knitting capacity.
