The electronic universal testing machine is an indispensable instrument for the flexible packaging industry and the film industry. By using the test for tensile strength, peel strength, puncture strength, tear strength and elongation, the quality problems in production can be avoided in advance. Reduce the loss to a small extent as much as possible. Be sure to be close to your own test materials, and have a comprehensive understanding of the performance of the commercially available tensile machines. After sex analysis, they will be purchased.
Different tension ranges, different force sensors, resulting in different structures will directly affect the cost of the instrument. For general flexible packaging manufacturers, a pull range of 300 Newtons is sufficient;
According to the performance and requirements of the flexible packaging film to be tested, the stroke can be 600-800mm;
The three basic configurations of intelligent: host, computer, and printer, if the microcomputer is powerful, you can print directly. It can also be equipped with a regular computer. If equipped with a computer, the manufacturer should give the corresponding control system. With a computer, you can perform complex data analysis, such as data editing, partial magnification, adjustable report formats, and statistical analysis of groups.
Second, the test project
Flexible packaging requires a multi-purpose tensile machine, that is, on the basis of different fixtures, it can be used for stretching, compression, bending, tearing, shearing, 180 degree peeling, and 90 degree peeling test.
Some commercially available tensile machines are in the range of 10~500 mm/min, and some are in the range of 0.01~500 mm/min. The former generally uses a common speed control system, and the cost is low, and the roughness affects the accuracy. The latter uses a servo system, which is expensive and has high precision. For flexible packaging enterprises, the servo system is selected, and the speed range of 1~500mm/min is sufficient, so that the accuracy is not affected, and the price is within a reasonable range. Note: The price is about 10,000 yuan, basically the speed control system, because the price of servo motor is about 4,500 yuan / piece.
Accuracy issues, including force measurement accuracy, speed accuracy, deformation accuracy, and displacement accuracy. These precision values ​​zui can be up to plus or minus 0.5. But for the average manufacturer, achieving 1% accuracy is sufficient. In addition, the force value resolution can almost reach one in 100,000.
The service life of the tension machine is generally more than five years for flexible packaging. In the face of the low-cost tensile machine of 1,000 yuan, is the after-sales service for several years in time? It is very worthy of scrutiny. Therefore, when purchasing a rally machine, we should fully consider whether the unit is dedicated to the profession, whether it has a complete after-sales service system, and whether it has a good reputation in the industry.
Fifth, the main configuration of machine machinery, machining accuracy
Transmission, screw drive and rack drive, the former is expensive, high precision, high test repeatability; the latter is cheap, low precision, low test repeatability. The flexible packaging of the tension machine is frequently used and requires high precision, so the screw drive should be selected. The lead screw has a decisive effect on the measurement of the pull force accuracy. Generally there are ball screws, trapezoidal screws, and general screw. Among them, the accuracy of the ball screw is high, but its performance depends on the operation of the computer servo system, and the whole price is relatively expensive.
The main cost of the sensor lies in the life. Photoelectric induction is one of the more advanced technologies. It can be used more than 100,000 times. It can be achieved by import and domestic joint ventures. Machining accuracy: In terms of the machining process of the tension machine, there are car, grinding, planing and washing processes; there are numerical control technology; wire cutting process; which processing technology is selected? Will directly affect performance, relationship prices.
