Rally machine maintenance should be aware of the problem:
One, Rally machine maintenance when the first should consider character need.
Tension range differences, just the use of sensor disagreement, is just a pulling machine layout, but this had little effect on the price. For the usual soft packaging manufacturer, tension in the range of 100N was right. So it was with single-arm is general. With single-arm type absolute should layout is door type structure, which is responsive to answer than large pulling force, such as 1T or above. So the flexible packaging manufacturers basic need.
Two, Rally machine maintenance experimental path problem.
In accordance with the soft packaging film need to test yield and requirements, road in 600 - 800 sister is general. Raw materials selection of road and over 1000% of general elongation of 1000 general perhaps 1200 sister.
Three, Rally machine maintenance standard configuration problem.
Intelligent three basic configurations: host, microcomputer, and the printer, if the microcomputer with strong general direct printing. In addition can also be equipped with a computer. There are computer, namely the general development of complex data analysis, such as data editing, a small portion of amplification, may mediate reporting forms, develop group style of statistical analysis. If fitted with computer, manufacturers should give to the corresponding control system.
In four, the output results of tensile machine maintenance.
The experimental results output can be arbitrarily set: maximum force value, elongation, tensile strength, elongation, tensile force force value, to obey the strength, modulus of elasticity, maximum test force 8. The general said microcomputer dominate, the output most one-sided results. Some manufacturers of manufactured goods, usually general output of the 8. Some domestic manufacturers general output 5-6, some manufacturers can output the maximum force value, average value, minimum value three.
Five, Rally machine maintenance in can execute project.
Soft packaging requirements tensile machine one machine with multifunction, with differences in fixture of the Genti foundation, can stretch, shrink, winding, tear, shear, 180 degrees, 90 degrees peel peeling test. The market situation of some high-end Rally machine in addition to the above items, because of its high precision sensor ( some reach 1/250000 ) also general defense coefficient test.
Six, Rally machine maintenance manufacture machinery primary configuration:
Transmission, a transmission and a rack gear, the former noble, uses in the high accuracy, high repeatability test; the latter for cheap, low accuracy, low test repeatability. Screw, the tension precision measurement has just sense guide. Usually has a ball screw, trapezoidal screw, usually screw. In addition, the ball screw of the rough degree highest, but to depend on the computer servo systems dominate the trick play, set price contrast noble. The screw and trapezoidal screw is general to flexible packaging required precision, i.e. 0.5 to 1% accuracy. Transmission, gear transmission and chain transmission, the former noble, used for high precision; the latter is cheap, low precision for. Sensor, the capital cost is life, is the feeling of photoelectric contrast advanced technology available, usually more than one hundred thousand times.
