3, the whole structure and software system using modular design, easy operation, good expansibility, convenient maintenance.
4, twisting module:
* mechanical false twisting device with independent intellectual property rights, building block type structure, stable operation, easy maintenance.
* design of the automatic feeding device of the first sample in China, and improve the efficiency of the test.
* twisting module uses the Swiss high-speed servo system speed, accuracy and stability.
* Visual twisting speed variable speed operation, accurate intuitive, automatic storage of different varieties of twisting parameters, convenient and fast call post test, simple operation.
5, the new digital speed control system, roller automatic import and export, extend the service life of roller.
6, a test can be synchronized with the output of the conventional test results and a variety of suppression, semi suppression and fragment test results.
7, test results of database storage, users can carry on various classification and statistics, analysis and retrieval of test results, can form a monthly, quarterly or annual report, to facilitate long-term user monitoring and statistical analysis of the trend of product quality.
8, data protection and reduction technology can effectively protect the various statements of computer storage data, and quickly solve a variety of software and hardware caused by the fault.
