Description

Technical Field

[0001] The invention relates to the technical field of thermal sensitive sheets, in particular to a method for measuring the life of glass on the surface of a thermal sensitive sheet. Background Art

[0002] At present, when a thermal printer prints thermal paper, the thermal paper will move relative to the thermal sheet. When relative movement occurs, friction between the thermal paper and the thermal sheet surface glass will cause loss of the thermal sheet surface glass. The existing standard for the life of the thermal sheet surface glass is: the thermal printer prints 50 kilometers of thermal paper without the thermal sheet surface glass being worn out.

[0003] The existing method for measuring the life of the thermal sheet surface glass requires assembling the thermal sheet to be tested onto a thermal printer, and using the thermal sheet to continuously print thermal paper until 50 kilometers of thermal paper is printed, and then detecting the wear of the thermal sheet surface glass to determine whether the life of the thermal sheet surface glass meets the standard. This method for measuring the life of the thermal sheet surface glass takes a long time, usually 15 to 30 days, to print 50 kilometers of thermal paper, and is expensive, costing 5,000 to 10,000 yuan per measurement. Therefore, it is necessary to design a method for measuring the life of the thermal sheet surface glass to reduce the time and cost of the measurement method. Summary of the invention

[0004] In view of the above problems in the prior art, the present application proposes a method for measuring the life of the surface glass of a thermal film, which can reduce the time and cost of the measuring method compared with the existing method for measuring the life of the surface glass of a thermal film.

[0005] The present invention provides a method for measuring the life of the surface glass of a thermal sheet, characterized in that the method comprises the steps of:

[0006] Assemble the thermal sheet to be tested onto the thermal printer;

[0007] Select a measuring paper with a surface roughness greater than that of the thermal paper to replace the thermal paper, and determine the printing length L of the measuring paper corresponding to the standard printing length when the printing length of the thermal paper is the same as the thermal sheet surface glass wear amount, according to the corresponding relationship between the printing length of the measuring paper and the printing length of the thermal paper;

[0008] Use the thermal sheet to continuously print the test paper. After printing the test paper of length L, check the wear of the surface glass of the thermal sheet to determine whether the life of the surface glass of the thermal sheet meets the standard.

[0009] In the above-mentioned method for measuring the life of the surface glass of the thermal film, further, the measuring paper is sandpaper.

[0010] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the present invention can be achieved.

[0011] A method for measuring the life of thermal film surface glass provided by the present invention has at least the following beneficial effects compared with the prior art: measuring paper with a surface roughness greater than that of thermal paper is selected to replace thermal paper, and a thermal film is used to continuously print the measuring paper. Since the surface roughness of the measuring paper is greater than that of the thermal paper, under the condition of the same amount of thermal film surface glass wear, the printing length of the measuring paper is less than the printing length of the thermal paper, and the printing length L of the measuring paper is less than the standard printing length of the thermal paper. Therefore, the thermal film only needs to print a shorter measuring paper to complete the measurement. Compared with the existing method for measuring the life of thermal film surface glass, the time and cost of the measuring method can be reduced.

[0023] The embodiment of the present invention provides a method for measuring the life of the surface glass of a thermal film, which can reduce the time and cost of the measuring method compared with the existing method for measuring the life of the surface glass of a thermal film.

[0024] See also Figure 1The embodiment of the present invention provides a method for measuring the life of the surface glass of a thermal sheet, and the method for measuring the life of the surface glass of a thermal sheet comprises the following steps:

[0025] S10: Assemble the thermal sheet to be tested onto the thermal printer.

[0026] S20: Select a measuring paper with a surface roughness greater than that of the thermal paper to replace the thermal paper, and determine the printing length L of the measuring paper corresponding to the standard printing length when the printing length of the thermal paper is the same as the printing length of the thermal paper according to the corresponding relationship between the printing length of the measuring paper and the printing length of the thermal paper when the amount of glass wear on the surface of the thermal sheet is the same.

[0027] S30: Continuously print the measuring paper using the thermal sheet, and after printing the measuring paper of length L, detect the wear of the surface glass of the thermal sheet to determine whether the life of the surface glass of the thermal sheet reaches the standard.

[0028] A measuring paper with a surface roughness greater than that of the thermal paper is selected to replace the thermal paper, and a thermal sheet is used to continuously print the measuring paper. Since the surface roughness of the measuring paper is greater than that of the thermal paper, under the condition of the same thermal sheet surface glass wear, the printing length of the measuring paper is less than the printing length of the thermal paper. The printing length L of the measuring paper is less than the standard printing length of the thermal paper. Therefore, the thermal sheet only needs to print a shorter measuring paper to complete the measurement. Compared with the existing thermal sheet surface glass life measurement method, the time and cost of the measurement method can be reduced.

[0029] Example

[0030] 1000-grit sandpaper was selected as the test paper. After comparative tests, the following data in Table 1 were obtained:

[0031]

[0032] Table 1: Corresponding relationship between the printing length of 1000-grit sandpaper and the printing length of thermal paper when the glass wear amount of the thermal film surface is the same

[0033] According to the data obtained in Table 1, it is determined that when the amount of wear on the surface glass of the thermal sheet is the same, the corresponding relationship between the printing length of 1000-mesh sandpaper and the printing length of thermal paper is in direct proportion. When the printing length of thermal paper is the standard printing length (50 kilometers), the corresponding printing length of the measuring paper is L=151÷60×50=125.8 (meters), that is, 1000-mesh sandpaper is used instead of thermal paper for printing. After printing 125.8 meters of 1000-mesh sandpaper, if the surface glass of the thermal sheet is not worn out, it can be determined that the life of the surface glass of this thermal sheet reaches the standard.
