And the role of the machine is to improve the internal structure of the note, thereby increasing its length fragment uniformity while reducing weight unevenness of the fiber sliver in the straight and parallel, reducing the hook, so the fineness of compliance, so that different types or different quality of raw materials mixed evenly to achieve the specified mixing ratio. And the machine according to the form of organization into drafting roller drafting and machine and gill two categories. English translation FA306A and of the machine (bìng tiǎojī) drawing frame introduces new FA306A and type of aircraft is to absorb foreign advanced technology and similar products at home and abroad spinning process characteristics and design a new generation machine, using three on three the pressure bar plus dual-zone line guide roller drafting system for 20-76mm cotton, pure and blended spun cotton fiber and long fiber spinning at the end of each variety and the stem can get high-quality sliver . Transmission fully enclosed oil bath gearbox, weight change gear mounted on the front of the box, shaking the handle to adjust the weight conversion and drafting multiple, convenient and reliable. Before the addition of multi-gear roll displacement device, a plurality of fibers suitable for spinning. To stand the pressure using the new structure, reasonable spring election materials, the pressure does not need to adjust and improve the stability and reliability of pressure. With a new structure of the guide bar frame design, arms support smooth transmission. The spinning machine to adapt to different needs throughout the tension can be adjusted; the electrical control uses PLC control system to improve reliability, the choice of variable frequency speed and touch-screen technology, interactive, convenient operation. With a stable and reliable automatic changer with directional stopping device, missing preliminary test and the test tube feeding tube apparatus in place, greatly reduce the labor intensity. The number of root carded or combed fiber strip after processing into fiber strips spinning machine has a certain quality requirements. And the role of the machine is to improve the internal structure of the note, thereby increasing its length fragment uniformity while reducing weight unevenness of the fiber sliver in the straight and parallel, reducing the hook, so the fineness of compliance, so that different types or different quality of raw materials mixed evenly to achieve the specified mixing ratio. And the machine according to the form of organization into drafting roller drafting and machine and gill two categories. Since the 18th century Ming Luola drawing hair and applied spinning, roving machine, since there roller drafting to bring additional sliver unevenness, so that products meet the requirements of uniformity, so the use of two or more strips merging to improve the uniformity, then it appeared early and machine. Later on the draft form and the machine again reformed by increasing the draft to two-zone drafting, and then replaced by a straight line drawn curve draft form, so that the quality sliver made significant improvement, but also achieved shrink Road. Since the 1950s, and of the output speed of the machine is improved quickly, from 40 to 60 m / min to 200 m / min or more, even up to 600 m / min. Part of the cotton and machine monocular, two, four, and other. The plurality of sliver feed, by merging, made after drawing a sliver of said monocular and the machine; the output of said two slivers eyes and the machine, over and so on. And each machine has a separate drive system. Main technical specifications suitable for spinning fiber length: 276mm Eye: 2 output speed: 2.47-10 m / s (200-600m / min) draft mode: the three on three under pressure bar plus dual zone curvilinear drafting the guide rollers. Longitudinal draw ratio: 40.13-13.556 doubly pressure type: spring loaded cradle or use pneumatic pressure devices. Cleaning method: use a clean cloth wiping rotation on rollers, a clean single apron wiping roller, Pied suction hopper through the suction outlet. Feeding root number: 4-8 Can specification: (mm) diameter feed 4,005,006,008,009,001,000 high output diameter 1100 300 350 400 500 1100,900 feeding high way: Overhead active feeding changer mode: Single electromechanical push rod drive chain, launched a full package while feeding air cylinder. Motor: Main motor 380V 3.5 / 0.8KW 4P / 16P suction motor 380V 0.75KW changer motor 380V 0.25KW 910r / min Transmission: Closed drive, high gear in an oil bath, using imported bearings. Brake: Brake electrolytic capacitors (non-inverter) or inverter brake (frequency). Automatic stop Type: Optical from the stop, the micro switch from the stop. Own Dimensions: 2020 * 800 * 1795 (mm) Weight: about 2150kg (net weight
