The basic principle of this series of silk cotton machine is that the double-gear shaft is used to hold the silkworm cocoon with the roller mechanism, and the high-speed rotating cylinder of the cylinder is used to cut the sputum, the moth, the double palace, and the lower leg. The cockroach is equally divided into fluffy soft silk. It is understood that the technical innovations obtained have the following points: First, the key components and technical parameters of the machine have been optimized to greatly improve the work efficiency; secondly, the mechanism for removing the velvet at both ends of the drum and the semicircular bevel are designed. The guide plate effectively solves the problem of winding of the silk thread on the main shaft and improves the yarn output rate. Thirdly, by optimizing the parameters such as the angle, length and diameter of the cylinder of the cylinder, the brush mechanism which is in constant friction with the needle roller is added. Etc., significantly improve the fluffiness of the silk cotton; Fourth, by appropriately increasing the distance between the bottom plate of the machine and the steel needle roller, lengthening the air outlet passage, and designing the impurity flow guiding mechanism at the slag door, the purity of the silk cotton is improved. The fifth is to use the brake braking device, which shortens the time for stopping the cotton and improves the work efficiency. The main technical performance indicators: productivity 16.1kg / h, noise ≤ 82.5dB, the maximum mass of a single blank of 1.0Kg, dust concentration <4.8mg / m3, energy consumption 6.4kwh / 100kg. Because the silk cotton machine developed by this project has stable comprehensive performance, low price, simple operation and maintenance, and is suitable for use in rural areas. In recent years, with the development of sericulture production, the promotion volume is gradually increasing, showing a good market prospect.
