FZ/T93060—2003
Nonwoven fabric carding machine is an important unit machine in the nonwoven fabric production combined machine. Since this machine can be matched with a variety of nonwoven fabric production combined machines, it cannot be used as a part of a certain combined machine standard when formulating standards, but needs to formulate product standards separately. This standard is proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the National Technical Committee for Standardization of Textile Machinery and Accessories. The drafting units of this standard are: Shanghai Textile Machinery Research Institute, Changshu Feilong Machinery Co., Ltd., Taicang Shuangfeng Nonwoven Fabric Equipment Factory, Yizheng Hairun Textile Machinery Co., Ltd.
The main drafters of this standard are: Shi Yaoxun, Lu Zhongbao, Han Xuelong, Fan Zhen, Wang Zhiguang, Lu Jianguo. 1 Scope

FZ/T 93060—2003
4.2.2 When the cylinder rotates at a speed of 350/min, its allowable unbalance should be 172gmm/kg. 4.2.3 The radial runout of the outer circle of the doffer to the axis is ≤0.05mm. 4.2.4 If roller stripping is adopted, the radial runout of the outer circle of the stripping roller to the axis shall be ≤0.035mm; if a chopping knife is adopted for stripping, there shall be no oil leakage in the chopping force box, and the box temperature shall rise by 25℃. 4.2.5 The amplitude of the cylinder frame shall be ≤0.10mm.
4.3 Transmission system
4.3.1 All transmission mechanisms of the whole machine shall operate smoothly without abnormal vibration. 4.3.2 The lubrication of each bearing shall be good, the temperature rise of the rolling bearing housing shall be ≤20℃, and the temperature rise of the sliding bearing housing shall be ≤25℃. 4.4 Safety requirements
4.4.1 The safety protection cover of the whole machine shall be safe and reliable. 4.4.2 The insulation of electrical equipment and lines shall be good, the protective grounding of the metal housing shall be correct, and the grounding resistance shall be ≤0.12. 4.4.3 The insulation resistance of electrical equipment shall be ≥1MQ. 4.4.4 Voltage withstand requirements for electrical equipment: the test voltage is ≥1500V (AC), the duration is 1min, and there is no flickering or breakdown. 4.5 The emission sound pressure level of noise when the whole machine is unloaded is ≤85dB (A). 4.6 Product coating shall comply with the provisions of FZ/T90074-1995. 4.7 The fiber web shall be uniform, without obvious stripes and cloud spots, and the fiber web unevenness rate CV is ≤3.5%. 5 Test method
5.1 The radial circular runout of the outer circle of the cylinder, doffer and stripping roller to the axis in Articles 4.2.1, 4.2.3 and 4.2.4 is tested with a dial indicator and a magnetic base.
5.2 Article 4.2.2 Dynamic balance is tested with a hard-bearing dynamic balancing machine. 5.3 Article 4.2.5 The amplitude of the cylinder frame is tested at the cylinder bearing seat with a vibrometer (or micrometer). 5.4 Article 4.2.4 If a cutting knife is used to peel the net, the temperature rise of the knife box shall be tested with a point thermometer. 5.5 Article 4.3.2 The temperature rise of each bearing shall be tested at its housing with a point thermometer. 5.6 Article 4.4.2 The insulation resistance shall be tested in accordance with the provisions of FZ/T99014-1995. 5.7 Article 4.5 The noise measurement shall be tested in accordance with the provisions of GB/T7111.1-2002 and GB/T7111.3-2002. 5.8 Article 4.7 The non-hooking rate of the fiber net shall be determined by the sampling and weighing method.
