We are the inventor of automatic down weighing and filling machine. All filling machines are applied in down garments enterprise filling process, and are applicable to 90, 80, 70, 60 and 50 down. High pressure air is used to absorb down through the automatic weighing system, and to fill the panel with a preset weight of down. With dual or triple or fourth weighting system, the speed of down-filling machine is 2-4 times faster than that of manual method, down-filling is no longer needed skilled workers. Non-contact weighing method is used and the highest precision of single down filling can reach 0.01g even 0.001g; According to given target gram weight, the actual down gram weight will be automatically increased or reduced as necessary during filling. At same time ,the application of central dust-removal system greatly improves the overall working and production environment of the down-filling workshop, it can lower down loss as well as reduce the cost of down and reuse the down.

Analysis of the total application of domestic CNC machine tools in key user fields
Aerospace is the project that best reflects the comprehensive strength of a country's manufacturing industry. It involves a series of equipment fields such as special alloys, processing technology, and electronic equipment. With the continuous improvement of the adoption rate of domestically produced equipment, it has promoted the technological progress of the machine tool industry and enhanced the competitiveness of the domestic machine tool industry. For this reason, domestic machine tool enterprises should intensify technological innovation and demonstrate China's comprehensive strength.
At present, the total amount of domestic CNC machine tools used in key user fields is not much. In some enterprises that are not complicated in the processing process, such as military industrial enterprises, they account for a large proportion, which can reach about 60% of the total equipment, but they are mainly used in the middle and low-end CNC machine bed machine. Most of them are two-axis economical CNC lathes, three-axis machining centers and CNC milling machines. The factory year is also relatively early. In some high-end applications, such as aviation companies, mainly used large-scale, composite, precision, multi-axis linkage high-end machine tools, requiring high rigidity and high efficiency of the machine tool, cutting difficult materials, a small domestic production Machine tools can often only be used in general processes or as ancillary equipment, and rarely enter critical manufacturing processes. Because domestic machine tools still lack innovation, there are still some problems in some aspects:
(1) The precision retention is not good, the processing accuracy of domestic equipment is reduced rapidly, and the equipment failure rate is high.
(2) The reliability is not strong. The numerical control system, driving power supply, lubrication and cooling system, control unit and functional components of domestic CNC machine tools have many reliability problems.
(3) The design of the machine tool is unreasonable, causing the parts to be easily damaged during use. The electrical design of some machine tools does not adapt to the working environment in the hot and humid regions of the South, resulting in frequent failures.
(4) The manufacturing quality is in urgent need of improvement. Some products are not subject to manufacturing quality. After using for a period of time and repairing some faults, the original spindle speed has to be discounted by half. In addition, when the machine tool reaches a certain speed within the specified speed range, the machining becomes unstable and the noise is large.
In fact, the great development of the aerospace equipment manufacturing industry has a strong driving effect on the machine tool industry. At present, the five-axis machining center is urgently needed. For processing large-scale launch vehicles such as launch vehicles and cabins, it is necessary to use a large tonnage spinning machine of more than 100 tons, a five-axis double-column vertical turning and milling center of φ3000 mm or more, a floor milling and milling center of φ16000 mm or more, and a wide gantry milling machine with a processing width of 2000 mm or more. Heavy duty machine tools such as machining centers.
At present, the aerospace equipment industry has both the support of national policies and the relatively certain performance expectations in the future. Under such new opportunities, domestic machine tools should accelerate development and innovate. We believe that in the near future, China's manufacturing and China's creation will gradually replace imports and make the contribution that Chinese aircraft operators should make.
