1, to buy electronic tensile machine should first consideration to execute test material tension category.

Tension of different categories, to the application of the sensor is different, also decided the pulling machine organs, but the impact on prices is not ( except for door type ). For a general soft packaging manufacturer, in 100 Newton rally category will have full. And also to accept single-arm is on the line.

With single-arm type corresponding to organ is a door type of authority, it is to answer according to large pulling force, such as a ton or more. To be flexible packaging manufacturers basic need.

In 2, electronic Rally execute machine implementation of routing header.

According to my company implemented the necessary items such as the elastic substance selection, larger, longer articles were implemented, ordering force execute machine will advance with the manufacturers of local communication technology. The soft packaging film as an example, its necessary to test them and asked, in 6001500mm namely or routing. The material elongation exceeds 1000% or 1000 or 1200mm selection field.

In 3, electronic Rally execute machine scale equipment device header.

Intelligent three root set device: host, microcomputer, and the printer, if microcomputer abide by the strong or direct printing. Also unusual computer equipment. With the computer, namely or miscellaneous comprehensive data, such as data editing, partially inflated, expand, can adjust the report mode, the group was statistical integration.

If fitted with computer, manufacturers should give in the corresponding control system.

In 4, electronic Rally execute machine output after all.

Execute after all output after all can be arbitrarily set equipment device: maximum force value, elongation, tensile strength, elongation, tensile force, force value to strength, modulus of elasticity, maximum strength 8. This or that the monopoly, the output most unilateral after all. Some overseas manufacturers of production, or the output of the 8. Overseas some manufacturers or output 5-6, some manufacturers can output the maximum force value, equal value, minimum value three.

In 5, electronic Rally execute machine in engineering can be used to perform.

Soft packaging requirements tension machine is a multi-purpose machine, namely in the different equipment fixture on the basis of drawing, do, tightening, winding, tearing, shear, 180 degrees, 90 degrees peel peeling implement.

On the market a number of high-grade tension machine in addition to the above works, because of its high precision sensor ( some reach 1/350000 ) or coefficient of test stand.

In 6, electronic tension implement mechanism works machinery main setting equipment device:

Transmission, a screw drive and gear rack, the former is low, for high precision, high test repeatability; the latter for low-cost, low accuracy, low test repeatability.

Screw, the tension precision measurements exist to sense guide. The general has a ball screw, trapezoidal screw, general screw. In addition, the ball screw of the rough degree highest, but its gritty play on computer servo system of monopoly power play, set prices were low. Admission to a general screw and trapezoidal screw, or reaches the soft packaging required precision, i.e. 0.1 to 1% accuracy.

Transmission, gear transmission and chain drive, the former for high accuracy; the latter is low, low, low precision for.

Sensor, primary cost in life, feel the advanced photoelectric control technology, the general availability of more than one hundred thousand, imports and overseas part of joint stock manufacturers or reach higher technology is home Shanghai Xinda instrument limited company

In 7, electronic Rally execute machine implementation of speed.

The market of equipment in some 10~500mm/min, some in the 0.001~500mm/min, the former general application of ordinary speed regulating system, low cost, roughness influence precision; the latter application servo system, low price, high precision, for the flexible packaging enterprises, selection of servo system, governing category 1~500mm/min is enough, so does not affect the accuracy, price in within a reasonable scope.

8, implement the measurement precision of electronic tensile machine.

Tension implement machine precision of title, poly force measuring accuracy, speed and accuracy, precision of deformation, displacement accuracy. These precision can reach the maximum value of plus or minus 0.5. But the general manufacturers, reach 1% accuracy is enough. In addition, stress distinguishing rate can reach 40 1/10000 near.
