The First Cotton Automatic Weighing And Sampling Equipment Was Born In China.

< p > < < a href= > http://www.91se91.com/news/index_p.asp > > Shanghai > /a > the inspection and Quarantine Bureau, led by the inspection and Quarantine Bureau, has completed the research and development of the high efficiency automatic sampling system for cotton weight and the construction of the demonstration base. It marks the first set of automatic dynamic weighing system of our country, which has completely independent intellectual property rights, a href= "http://cailiao.sjfzxm.com/" > sampling equipment < /a >, which is a major innovation of the General Administration of quality supervision, inspection and quarantine in the "a" href= "/a" > textile raw material detection.

< p > cloudy and rainy, cold and windy, and biting cold wind blew on the cheeks.

Qian Qian, who was waiting for inspection at the port and his 11 colleagues, welcomed a batch of newly imported cotton.

In order to get the first pass for cotton weight and quality, they should weigh the imported cotton bags and manually enter the cotton bag at a certain depth for sampling.

Master Qian said, "12 people, two cranes work at the same time, a batch of cotton 3000 packs, the fastest also has to work 3 days to complete."

Less than P, all of this is now expected to become "old memories" in the photo recording.

The rewriting of history is precisely the construction of the research and demonstration base for the efficient automatic cotton sampling and weighing system, which is led by the Shanghai inspection and Quarantine Bureau.

< p > it turned out that the on-site inspection of weighing and sampling of imported cotton was also a "hard job" - wearing a thick down jacket, and the piercing cold wind on the harbor could pierced the skin densely like a small needle.

After entering the country, a group of 3000 bags is taken as an example. 12 people are divided into 3 days, and the field operation can be completed more than 8 hours a day.

< /p >

< p > it is not easy for inspectors to weigh and sample on the line day after day.

What's more difficult is that the traditional weighting method is "weighing", manual handling plus manual counting.

< /p >

"P > these extremely traditional manual modes are in sharp contrast to the large quantities of incoming cotton coming into the country.

Master Qian said that due to tightened hands and low efficiency, the process often did not flow.

< /p >

< p > cotton is an important strategic material of the country and belongs to bulk raw materials.

As the leader of the world textile processing industry, China has a very large demand for cotton. It needs to import about 3 million tons of cotton from abroad to fill the gap every year.

The inspection and quarantine department's cotton inspection certificate is the basis for the Sino foreign trade in cotton trade. Therefore, the acceptance of the weight and quality of imported cotton has always been the focus of attention in the industry.

< /p >

< p > cotton has made new breakthroughs in the reform and development of laboratory inspection techniques and testing methods, and its weight inspection and sampling site work methods have not changed.

Such a mode of work requires a lot of labor and intensity, especially when the import volume of cotton is large. The heavy weight inspection and sampling process cause great burden on the inspection work, and the problem of delay claims often occurs.

In addition, to record and analyze large amounts of data manually, the sampling process can not be strictly controlled, which brings great uncertainty to the quality of inspection work.

In the actual work of cotton inspection at various ports, this has always been a very thorny problem.

< p > < strong > solving problem < /strong > < /p >.

At the beginning of 2011, Xu Jinji, director of the Shanghai inspection and Quarantine Bureau, was the head of the project to solve the problem of the field inspection of imported cotton. The research project of the State Quality Inspection Bureau, "the development of the high efficiency automatic cotton weight sampling system and the construction of a demonstration base", was undertaken by the Shanghai inspection and Quarantine Bureau.

Speaking of the research direction of the project, director Xu Jinji said that from the following aspects: how to reduce labor force, ensure quality and improve efficiency, we must use automatic equipment to achieve accurate and fast inspection! {page_break} < /p >

< p > after the project team went to several warehouses for field research, a preliminary design plan for cotton weighing and sampling equipment was formed.

In the face of the initial positioning design, Tang Minfeng, deputy director of the Shanghai provincial inspection and Quarantine Bureau's raw materials center, who has long been rich in cotton inspection experience, said: "it has been done manually by pushing cotton bags onto the scales for a long time. If we can achieve dynamic weighing, how much will it change?" < /p >

< p > so the project team began to look up the data, modify the design and devote much effort to research. Although dynamic weighing technology is applied in other fields, there is still much work to be done to apply this technology to the inspection of imported cotton.

After continuous practice, the project team changes the static weighing to dynamic weighing under the premise of ensuring the accuracy of the data, and the dynamic electronic weighing device completes weighing on the delivery of cotton bags, which greatly improves the work efficiency.

< /p >

< p > the solution of dynamic weighing technology has encouraged the morale of the project team.

But for the front-line inspection work, the most time-consuming and labor-intensive sampling work is cotton.

A cotton bag, each package belt can withstand up to 0.8~1 tons. It is difficult to remove cotton samples by manpower.

The sampling work in the United States is semi-automatic, but it is only applicable to the United States cotton with uniform cotton size. Moreover, the equipment in the United States is unable to remove the cotton baling outer packing material, the packing belt and the surface cotton, so the design can not be applied to the imported cotton inspection with different specifications in China.

For the complete technical gap, the project team is not discouraged, but rather brainstorming. On the basis of carefully studying the characteristics of each country's cotton bags, through repeated experiments and improvements, a unique circular cut sampling design scheme has been formed.

The skillful cooperation of sampling knives and cotton claws in the hands of cotton sampling machine can realize two key steps of automatic completion of "cotton removing" and "cotton sampling". The whole sampling method of the equipment ensures the stability of the natural form of the sample, and the samples are smooth and standardized, so as to meet the technical requirements of the inspection standard.

< p > Gao Youjun, head of the cotton technology team of the AQSIQ, said: "the cotton sampling technology has effectively solved the representativeness of the samples and is a very practical value."

< /p >

< p > < strong > innovation < /strong > < /p >

< p > the spark of innovation is everywhere in this project.

The project group adopted the method of "stacking sampling" in the design of the whole equipment. Weighing and sampling two modules can work at the same time. The weight inspection can be done at the same time, and the sampling can be completed at the same time, so that the on-site inspection of 600~900 cotton can be completed at an hour, and the efficiency is more than 5 times of the manual mode.

< /p >

< p > under the creativity of the project team, the imported cotton has its own "identity card".

< /p >

< p > the control system of the equipment has complete functions. It can manage cotton bag information, automatically store and process test data, print barcode labels and carry out remote data pmission. The application of digital technology not only makes the traceability of cotton inspection data possible.

With the "identity card", it can be queried anytime and anywhere, and the timeliness is high. It can maximize the time for the claim of imported cotton and lay the foundation for the next step to realize the on-site electronic supervision of imported cotton.

Seeing the birth of the new results, master Qian said excitedly, "a batch of 3000 packs of cotton has been completed in less than 1 days, and it is fully automated. Before I retire, this heart disease is gone."

< p > the R & D team of the project has successfully developed the first set of China's first cotton automatic weighing and sampling equipment with completely independent intellectual property rights, and completed the research and development tasks on schedule, and successfully passed the technical appraisal.

< /p >

< p > the opinions made by the Accreditation Committee composed of famous experts inside and outside the system are: "meeting technical indicators, filling the gaps in the world, and reaching the international advanced level."

This is an important milestone in the development of imported cotton inspection technology in China.
