Electronic fabric strength machine is one of the test instruments. The principle is a constant speed elongation (CRE) tensile testing machine - a type of testing machine where the elongation of the sample is consistent with the time. The entire width of the specimen was clamped on the fixture of a tensile tester and the specimen was stretched until it broke. The tensile properties of the specimen were recorded and calculated from the recording device of the testing machine. A common test method is the twisted-strip test method: it is suitable for textile fabrics, and the sheared yarn test method is applicable to non-woven fabrics, felt-down fabrics, and dipped fabrics or coated fabrics. Electronic fabric power machine consists of two parts, namely the computer control part and the speed control part. Microcomputer control part: Installed in the display/control box, it is based on the W77E516 single-chip microcomputer and consists of force sensor, photoelectric encoder, operational amplifier, AD converter, interface circuit, setting and control buttons, and display (Chinese LCD screen ) And printers and other components. This part controls the operating status of the instrument and performs data processing on the test values, which are then output by the display or printer.
Electronic fabric strength machine speed control part: installed in the speed control box, the instrument's driving down, rising and its operating speed adjustment is controlled by the control panel installed on the control box. Instrument physical quantity, power conversion using high-precision load sensor, and through the chopper wave stabilizer operational amplifier, the analog quantity increased to a certain extent, and then through the 16-bit A / D converter to convert the analog quantity into a digital quantity into the computer.
Electronic fabric strength machine elongation value, elongation value measurement, with an extension encoder to convert the amount of displacement into a pulse, and then use the interface circuit into the computer, the computer according to the input information, calculate the elongation and elongation: Each The pulse represents the amount of displacement per pulse = 0.005 mm. Time test: The internal crystal oscillator generates the clock pulse by frequency division. The internal counter produces a 0.1mS time signal and is recorded by the computer's internal register. Number of test counts: Each time the start button is pressed, when the A/D conversion has completed a valid test, the internal register is added for recording, and according to the number of set times, the count (sample number) is displayed and the number of test samples is displayed ( Number of times) and cumulative test times (total number of times). With different working principles, electronic textile strength machines will have different results. Therefore, testers must learn and study standards.

Introduction to the principle of electronic fabric strength machine
Introduction to the principle of electronic fabric strength machine With the development of science and technology, people are also gradually increasing the requirements for various matters in life. In people's view, when a product is manufactured and delivered to the market and sold, the product is recognized and the quality of the product is reliable. Therefore, for the final procedure in production, inspection is critical. And all kinds of test instruments play an important role.
