Fading ink printing equipment

Abstract

The invention provides fading ink printing equipment and relates to the technical field of printing, the fading ink printing equipment comprises a machine table, the machine table is composed of an upper frame, a lower frame and five sets of supporting frames, the upper frame and the lower frame are arranged up and down, and the five sets of supporting frames are used for supporting the upper frame and the lower frame. Production equipment is convenient to clean, the printing speed is high, when urine makes contact with the printing ink urine display, printing ink is washed away by the urine, the color disappears, and the prompting effect is achieved, and the physical change mode does not involve chemical reactions and is safe and harmless to use of infants; the feeding tension force can be conveniently adjusted, the two sets of guide rods are driven to be separated or folded along the sliding rollers through stretching and retracting of the two sets of telescopic rods of the two-way telescopic air cylinder, and therefore the slitting width is adjusted, and manual adjustment is not needed.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to fading ink printing equipment. Background technique [0002] The commonly used urine display in the existing diapers is mainly the hot-melt urine display glue technology. The urine display glue used in the hot-melt urine display technology is a combination of hot-melt adhesive and substances that are color-sensitive to pH. . When the urine soaks the diaper and transfers to the surface of the diaper, it changes its pH value, causing a color change. This is similar to the well-known pH test paper to measure the pH of the solution to measure the amount of urine. The existing urine-displaying glue used in diapers generally has the following problems: [0003] 1. The main resin used for urine-developing glue is generally polymer elastomer, tackifying resin, surfactant, and PH indicator. It is required that urine-developing glue has a strong indication of acid-base solution, so that...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides fading ink printing equipment, which solves the problem that the urine volume cannot be judged by the urine display when the traditional urine display gel is used, the temperature requirement is strict when the traditional urine display gel is coated, and the traditional urine display gel is sensitive to the environmental humidity. , the problem that the pH of the material is too high, and the adjustment of the feeding tension of the existing printing equipment and the adjustment of the slitting width are very inconvenient.
