As we all know, industrial sewing machines have been operating at high speed for a long time. When the rotating speed reaches 4000 rpm, the rotating shuttle speed is 8000 rpm. Many domestic rotary shuttles can't reach this speed. If the rotary shuttle can not supply oil well, there will be some technical problems, such as serious wear of hob, high noise, and so on, and then there will be some problems, such as broken wire, poor stitch and so on. And other issues. Especially when summer comes, the temperature of the shuttle will rise very high, and even the shuttle will get hot and the shuttle shell will not come out. At this time, the fuel supply of the shuttle will be adjusted.
We can find a piece of cardboard under the hook, run the machine continuously for at least 1 minute, and then check whether the oil on the cardboard is moderate. If there is no or little oil in the paperboard, we adjust the oil adjusting screw to the screw head, block the oil return hole completely, and then check the oil quantity. If the oil stain is still very small, it indicates that there is a problem in the oil circuit, which should be checked by simple and complex methods. Welcome to the company's official website www.ch-sewing.com.
We first remove the hook and then check the oil level. If the oil stain becomes larger after the hook is removed, the hook is blocked by dust. We can clean it, especially the oil hole felt at the track. If the hook is worn too much, please replace it with a new one; If the oil volume is still small, remove the lower shaft copper plug to check whether the filter is blocked, and remove the machine to check the lower shaft. During fuel injection, if the oil circuit is normal, a large amount of oil will flow out.
If there is still no oil flowing out, should we check whether the oil pump is normal? Is the rubber connection between oil pump and aluminum oil pipe broken or bent? If there is no such problem, the lower shaft gear screw and retaining ring should be removed to take out the lower shaft, and then the machine, seamless jacquard tights and other products, with the characteristics of high production speed, low labor cost and low cost. Low energy consumption, wide adaptability and instant production. At this time, a large amount of oil should flow out of the bushing, indicating that the oil hole of the lower shaft is not aligned with the bushing hole.
The simplest way to judge is to check whether there are friction marks at the oil hole of the lower shaft. There should be no friction mark on the oil hole. The market share of seamless weaving equipment in China's underwear industry is about 5%. However, from the perspective of development trend, seamless clothing will become the upgrading substitute of traditional textile clothing. At this time, the hole of the lower shaft is directly opposite to the oil hole of the positive bushing. Adjust the left and right position of the lower shaft according to the friction trace, and then check the oil quantity. After adjustment, the bottom shaft should be prevented from flowing left and right. If there is no oil in the sleeve after removing the lower shaft, check whether the oil holes of the oil pump, oil pipe and bushing are blocked or damaged, and pay attention to whether the oil pipe is inserted into the wrong hole.
After the above inspection and adjustment, we can adjust the oil level adjusting screw to the right position. This is mainly due to the fact that after more than 10 years of rapid expansion, the focus of domestic sewing machine enterprises has shifted to improving their innovation ability. If the amount of oil is too large, the fabric will be polluted.
