1. The quality needs should be considered first when repairing the tensile machine.
The difference of the pulling force range determines the different sensors used, which also determines the structure of the pulling machine, but this item has little effect on the price. For general flexible packaging manufacturers, a pull force range of 100N is sufficient. Therefore, it was decided to use a single-arm type. The structure corresponding to the single-arm type is the door type structure, which is suitable for relatively large tension, such as 1T or above. Therefore, flexible packaging manufacturers basically do not need it.
2. The test stroke problem during the maintenance of the tensile machine.
According to the performance and requirements of the flexible packaging film, the stroke is only 600-800mm. If the elongation of the material exceeds 1000%, the stroke 1000 or 1200mm can be selected.
3. Output the result when the tensile machine is repaired.
The test result output result can be arbitrarily set: maximum force value, elongation rate, tensile strength, constant elongation, constant elongation force value, yield strength, elastic modulus, maximum test force 8 items. This can be said to be the most comprehensive result output during microcomputer operation. The products of some foreign manufacturers can generally export these 8 items. Some domestic manufacturers can output 5-6 items, and some manufacturers can only output the maximum force value, the average value, and the minimum value.
