The spinning temperature is 270°C, the spinneret has a single hole, the diameter of each hole is 1mm, the spinning speed is 0.1g / min / hole, and the winding speed is 100m / min.

[0092] In this device, the connecting rod is made of aluminum-magnesium alloy, the contact member is made of steel, the air bearing is made of aluminum-magnesium alloy, and the base is made of steel. The mass of the air bearing 1 is 300g, the shaft sleeve 13 is cylindrical, narrowed in the middle, and its outer circumference is 8cm. The connecting rod 3 is hollow tubular, and its length is 40cm. The circumference of the cross section of the connecting rod 3 is about 10cm. The connecting rod 3 is connected with the air bearing 1 in a helical manner. The base 2 supports the c...

Embodiment 2

[0109] use as figure 1 The fiber tension measuring device shown measures the tension of polypropylene (PP) fibers. The raw material for melt spinning is polypropylene (PP), a product of China National Petroleum Corporation Liaoyang Petrochemical Company, grade 70318, weight average molecular weight 2.4*105, polydispersity coefficient 2.8, melting point 165-170°C, spinning grade. The spinning temperature is 280°C, the spinneret has 24 holes, each hole has a diameter of 0.2 mm, the spinning rate is 0.3 g / min / hole, the winding speed is 1000 m / min, and there are 24 fibers per bundle.

[0110] In this device, the mass of the air bearing 1 is 1 kg, the shaft sleeve 13 is cylindrical, slightly convergent in the middle, and its outer circumference is 15 cm. The connecting rod 3 is hollow tubular, and its length is 50cm. The circumference of the cross section of the connecting rod 3 is less than the circumference of the shaft sleeve of the air bearing 1, which is about 10 cm. The c...

Description

technical field [0001] The invention belongs to the technical field of force measuring devices, in particular to a device for measuring fiber tension, which can perform real-time measurement. Background technique [0002] Measuring the tension of fibers is of great significance to the production of textile industry. [0003] Because fibers need to be produced continuously, traditional force-measuring devices, such as balances and spring scales, cannot be used to measure their tension. At present, mechanical measuring equipment and electronic measuring equipment are generally used to measure fiber tension. As the disclosed yarn tension meter of patent application No. 94239787 and the disclosed portable digital tension meter of patent No. 86206741. However, there are some shortcomings in the above-mentioned device, which are mainly manifested in: the parts in direct contact with the fibers are fixed metal parts or ordinary bearings, and the frictional resistance between thes...
