China Made XJ128 Fast Cotton Fiber Performance Tester.

< p > cotton is a strategic material related to the national economy and people's livelihood. Its importance is self-evident.

However, for a long time, cotton inspection in China is mainly based on visual inspection after sampling. It is not only lack of scientific and impartiality, but also prone to economic disputes.

< /p >

< p > international application of HVI is widely used to test cotton comprehensive quality in a comprehensive, rapid and accurate way.

After China's entry into WTO, the need for cotton inspection methods and standards is becoming more and more urgent.

By the end of 2003, the national development and Reform Commission and other five ministries and commissions jointly issued the "cotton quality inspection system reform plan" approved by the State Council. This article emphasized the importance and necessity of using the cotton rapid testing instrument, and demanded the implementation of the domestic fast cotton comprehensive tester.

Against this background, Shaanxi Changling textile mechanical and Electrical Technology Co., Ltd. opened the mileage of developing domestic HVI.

< p > after years of design, research and industrialization, the XJ128 fast cotton fiber performance tester has been recognized by the industry, and has made a big step forward in the design and manufacturing technology of cotton inspection equipment in China.

< /p >

< p > < XJ128 > fast > a href= "//www.sjfzxm.com/news/index_c.asp > > cotton fiber < /a > performance tester is integrated with light, machine, electricity, gas, computer and network technology. It can detect cotton fiber's length, strength, Ma Kelong, color and impurity, and so on. The whole machine system is complex, high degree of automation and high reliability."

Lv Zhihua, deputy general manager of the project, first introduced the main functions of the tester.

< /p >

< p > in addition, the tester can also give the cotton fiber's average length, upper half length, uniformity index, short fiber index, specific strength, elongation, maximum breaking load, micron value, maturity index, reflectivity, yellow depth, color level, impurity particle number, impurity area percentage and impurity level.

< /p >

A href= "//www.sjfzxm.com/news/index_c.asp" > test instrument < /a > main technical indicators, including the maximum length of test 48mm, the upper half of the average length error of + 0.4mm, the uniformity index error: + 0.9%; intensity index: intensity error + 1.2gf/tex, elongation error + 1%; the quality of the sample: 10.0g + 1.5g, equine range 2 to 6.5mic, micron error: + +; color index: reflectivity (x) error + 1%; yellow depth (x) error + 0.5; impurity index: impurity resolution: *, impurity area error + 0.2%, impurity particle number error + 6; test efficiency: a sample inside the test. < p >

According to Lv Zhihua, according to Lv Zhihua, the tester mainly consists of the main processor, the long / strong host, the color host and the UPS, the bar code reader and other parts.

"According to the length and strength of cotton fiber, we have adopted different measuring methods."

Lv Zhihua further explained that for example, the length measurement was based on the photoelectric detection method. The intensity measurement was carried out by the method of constant velocity pulling of the bundle fiber. The method of compressed air was used in the measurement of the equine, the reflection spectrum analysis method of 45/0 illumination was used for the color measurement, and the CCD optical image analysis method was adopted for impurity measurement.

"P > night and day's painstaking research and development has not been wasted." the success of the XJ128 fast cotton fiber performance tester is of great significance for promoting the reform of cotton quality inspection system and improving the quality of cotton inspection technology. "

The expert group's conclusion is the best proof for the Lv Zhihua team.

< /p >

< p > ensuring the uniformity and sensitivity of large area < a href= "//www.sjfzxm.com/news/index_c.asp" > silicon photocell < /a >, controlling mechanical interference in the measurement of length and strength and the interference of various weak signal and noise, and establishing a variety of index algorithms and correction models are all challenges for the R & D team.

In particular, the realization of data networking function, the function of the network system, including the test results of each machine, can be uploaded to the national cotton quality inspection system reform data center, and the data center can view the state parameters, setting parameters and remote control of each machine.

< /p >

< p > this kind of tester with independent intellectual property rights is natural for innovation. When it comes to the uniqueness of XJ128, Lv Zhihua said that the long / intensity measurement realized the automatic sampling by cage rotary mechanism. The sampling pressure plate shape was finger shape, imitation manual sampling, which ensured the uniform and constant sampling pressure, improved the sampling success rate, reduced the influence of manual sampling on test data, and reduced the measurement deviation by the double comb clamp and double station measuring device.

< /p >

< p > efficient and stable detection is reflected in all aspects. Lv Zhihua further introduced that: "pneumatic control cotton sample carding device, smooth movement and high reliability; when the strength measurement, the length of the broken fiber is related to the length, which ensures the correctness and consistency of the strength test index; the constant current control of the color power supply ensures the stability of the color testing index; the adjustable negative pressure system can make the waste cotton rotate together with the air flow, thus ensuring the stability of the air flow during the test."

< /p >

< p > up to now, the company has sold 92 sets of testing instruments to achieve 62 million 560 thousand yuan in total industrial output value, 62 million 560 thousand yuan in new sales revenue, 26 million 450 thousand yuan in profits and taxes, and a profit of 23 million yuan.

The company expects the annual sales volume to reach 60 sets, and its product performance can replace imports, and the price is only half of the imported products.
