一：CFJ系列紧密纺装置简介
CFJ Compact Spinning Assembly Introduction
我公司研发的紧密纺装置采用网格圈积极传动结构，
主要由异形管（又称负压管）、网格圈及其张紧装置、输出罗拉、带齿前罗拉、过桥齿轮及其附件、输出上罗拉（皮辊）、皮辊架、罗拉座以及紧密纺负压系统等零部件组成。
其中，带齿输出罗拉安装在异形管内，带齿前罗拉输出的动力通过过桥齿轮传动给带齿输出罗拉，网格圈在带齿输出罗拉和输出皮辊的作用下积极传动，异形管负压由安装在车尾的紧密纺风机经总风管提供。针对国内细纱机的结构特点，本装置采用六锭为一个单元的模块化设计，不论老机改造还是新机配套都能胜任。该纺纱技术主要通过负压气流的作用将纤维收缩、集聚，使须条边缘上的纤维快速有效的向须条中心集聚并伸直，最终最大限度地减小纺纱三角区，从而大幅度减少突出于纱线本体外的毛羽，提高纤维的强力利用率，成纱强力得以提升。
Compact spinning system developed by our company is adopted mesh apron structure of active transmission, it mainly consist of following parts such as special pipe(also known as negative pressure pipe),mesh apron & tensioning device output roller, belt tooth front roller, idle gear accessories, output roller (roller) rubber cot brakes, roller stand and negative pressure system components of compact spinning. For the machine, toothed output roller is installed in the special tube, Toothed front roller Output driving force to toothed output roller through idle gear mesh apron conduct active transmission under action of toothed output roller compact spinning ran is installed in the rear of machine, it provides negative pressure pipe through the total wind pipe. As for character of structure characteristics of domestic spinning machine, the device adopts six spindles as a unit of modular designing; it is suitable for renovation of old machine and new machine. The spinning technology can conduct fiber contraction and agglomeration through the negative pressure airflow, this, fiber conduct quick and effective agglomeration and straightness towards spun center on the edges of spun, we could minimizing the spinning triangular space, we could greatly reduce outer yarn hairiness, we improve utilization of fiber strength and yarn strength during the process.
采用四罗拉结构，皮辊夹持网格圈积极传动。适用于国内外各种细纱机配套或改造。
With 4-roller structure, the roller clamps grid ring to actively drive. It is applicable to domestic and matching and transformation.
吸风系统采用透明玻璃管连接，不影响挡车工视线！
Air suction system is connected by transparent glass tube and will not affect the sight of spinner!
异型管优化设计，配耐磨片，增加使用寿命，更换紧密纺、赛络紧密纺方便，紧密纺耐磨片优化设计，延长皮辊回磨周期，增加皮辊使用寿命。为客户节省使用成本。网格圈，张力架更换方便。
Special-Shaped tube is of optimum design, equipped with wear-resistant sheet to increase service life and convenient to change compact spinning and siro compact spinning; with optimum design of compact spinning wear resistant sheet, it prolongs grinding cycle of roller, increases service life of roller and save using cost for customers. It is convenient to change grid ring and tension rack.
二：纺纱环境要求
Spinning environmental requirements
一：纺纱车间的温、湿和空气含尘浓度要求：
（1）温度：全年25~30°
（2）相对湿度：55%±5°C（棉）
（3）空气含尘浓度<3mg/m?
二：建议配备巡回清洁器
Temperature, humidity and air dust concentration requirements in spinning workshop:
1.1 Temperature: 25~30° all the year
1.2 Relative humidity: 55% ±5℃(cotton)
1.3 Air dust concentration < 3mg/m^3
Recommended to configure travelling cleaner
三：CFJ紧密纺装置使用效果
Use effect of CFJ compact spinning device
1. 减少毛羽、3mm以上毛羽可降低60%以上;
Reduce fuzziness, and the fuzziness over 3mm can be reduced by 60% above;
2. 在相同纺纱条件下，成纱强力比普通环锭纺提高5%-15%;
In the same spinning conditions, the finished yarn strength is improved 5%-15% more than ordinary ring spun yarn;
3. 改善细纱条干CV值;
Improve CV value in spinning production;
4. 改善工作环境，减少车间飞花。
Improve work enviroment and reduce flying in workshop.
四：改造和安装
Transformation and Installation
使用本装置对细纱机进行紧密纺改造，不破坏原设备的任何零部件，只需更换牵伸部分，罗拉座、前罗拉、吸棉笛管，车尾风箱。另增加紧密纺部件即可。
Use this equipment to transform the spinning machine for compact spinning, which will not damage any component of the original equipment and only needs to change drawing part, roller seat, front roller, suction flute and rear bellows. It can work only by adding compact spinning parts in addition.
