Technical Field

[0001] The present invention relates to the technical field, and specifically to a combined wire pressing and slotting machine for producing cartons. Background Art

[0002] Carton slotting refers to cutting out the folding lines of the upper and lower covers of the carton on a whole piece of cardboard. The process is carried out after printing and simultaneously with wire pressing. Indentations are pressed on the cardboard to produce wire presses, so as to facilitate folding the cardboard into a carton through the wire presses. For existing combined wire pressing and slotting machines, when carrying out wire pressing and slotting operations, the corresponding wire pressing knives or slotting knives need to be installed to process the cartons. In this way, during work, the wire pressing knives and slotting knives need to be replaced back and forth, and the wire pressing knives and slotting knives are frequently disassembled and installed, which is rather troublesome and reduces work efficiency.
