Technical knowledge of carton machinery technology: unreasonable solutions for printing grooved crimping wheels:

　　 1. The structure of the crimping wheel is improved, and the structure of the crimping wheel can be adjusted to appropriately increase the step transition arc radius of the crimping wheel;

　　2. Adopt the pre-compression destruction method to pre-compress before the formal crimping. Its disadvantage is the formation of more obvious traces of pressing lines;

　　3. The quality of the base paper is required to be good. For the cardboard with higher requirements, better quality face paper and lining paper should be used;

　　 4. Properly control the depth of the pressure line. Control the gap between the upper and lower crimping wheels according to the thickness of the processed cardboard so that the cardboard can be properly crimped;

　　 5. The moisture content of the base paper and cardboard should be appropriate. The worse the quality of the base paper, the drier the paperboard, the higher the probability of cracking of the pressure line;

　　6. Control the alignment of the center lines of the upper and lower crimping wheels to prevent the crimping wheels from being misplaced;

　　7. For cardboard with particularly poor base paper quality, use a line toucher to touch the line;

　　 8. If the pressure line is broken due to the drying of the cardboard, water spray can be used to increase the moisture content of the cardboard;
