Knitting machines are widely used in China’s textile and other industries. The braiding machine system is also made up of different parts, and the role of the yarn tube in the use of the braiding machine is also very important. How to maintain the bobbin of the knitting machine in use, and what inspections must be done for maintenance is a problem that everyone pays special attention to. The following is a brief introduction to the relevant problems, and I hope to be of some help to you.
What should be checked when maintaining the yarn tube of the knitting machine: The spindle is driven by a spindle belt. The spindles used in spinning machines are equipped with cotton webbing and nylon belts. Cotton spindle belts have a large stretch, short application period, and low price; plastic spindle belts have a stable transmission system, small vibration, low noise, are environmentally friendly and energy-saving, and have a long service life, but are more expensive. Advancing with the times, plastic spindle straps replacing cotton woven spindle straps is a development trend and is very worthy of marketing and promotion.
The quality of the yarn tube is very special to the application of the spindle. To choose bobbins made of high-quality raw materials (such as ABS, PC, PP), regular maintenance of bobbins in use should be further strengthened, and defective bobbins that are deformed or damaged must be removed resolutely and immediately. If poor quality or deformed bobbins are used, it will inevitably increase the unevenness of the spindle, increase the load on the spindle bearings, and shorten the service life of the spindle.
The spherical surface of the yarn tube and the spindle (also known as the “super eye”) should be evenly sealed, and the sealing surface should be no less than 85% to ensure reliable integration, synchronization, and stable operation of the yarn tube and the spindle. Generally, yarn bobbins should be inspected for maintenance in half a year to one year. The contents include.
- Cleaning: Remove silk waste, flying flowers, and dust, and eliminate waste silk waste in the “Super Sky Eye”.
- Spindle set: Use the standard spindle to set the bobbin, and check the number (±1.0mm) of the bottom hole (0.05-0.15mm).
- Test tube: When the spindle speed is 18,000 rpm, it is better to estimate or feel the amplitude of the upper end of the yarn tube ≤ 0.15mm and the lower end ≤ 0.25mm (180-190mm yarn tube). At the same time, it removes deformed and bent bobbins, rough surfaces, and scratches.
