Main structural features
1, the use of four roller compact spinning roller and output roller bridge gear grid ring active drive;
2, tight spinning negative pressure system using the total fan, the total air duct and equipped with filter device to prevent secondary pollution workshop;
3, negative pressure distribution system configuration is reasonable, the suction air flow consistency is good;
4, profiled pipe suction design is reasonable, is conducive to the collection;
5, the use of frequency conversion technology in the spinning of different branches of the yarn to control the negative pressure;
6, grid ring tension device consistency is good, to ensure smooth operation of the grid circle;
7, tight negative pressure control using frequency control method to ensure that the spinning process pressure stability;
8, automatic control of negative pressure stability, improve the degree of automation equipment.

Four roller compact spinning device
1, the company used four roller compact spinning and tight match spinning device on the spinning frame to transform, reasonable structure design, excellent parts manufacturing, spinning effect is obvious;
2, the yarn is more clean and smooth. Hair yarn hairiness was significantly reduced, more than 3mm hair follicle can be reduced more than 50%;
3, strong than ordinary ring spinning increased by 5% -10%;
4, the stem CV% better than ordinary yarn;
5, the traditional spinning machine ring spinning the same quality yarn or with the same raw materials can be spinning more high-quality high-yielding yarn;
6, the decapitation rate was significantly reduced, the yield increased significantly. The intensity of labor workers decreased significantly, flying significantly reduced. Business costs are falling。

Special section tube
, special section tube and output is small roller combination structure, convenient use and transform the siro spinning, convenient maintenance, maintenance on both ends of the bearing is easy to operate.
2, the optimization design idea
3, the better yarn quality
4, single yarn and siro spinning optional
5, stability, better and more efficient
	Roller rack Imported famous brand of raw materials, ensure that the product of tensile strength, antistatic performance, prolong service life, good consistency
