Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary center-splitting knives for printing machines, in particular to an auxiliary center-splitting knife for a seven-color printing machine. Background Art

[0002] As the name implies, the middle cutting knife device refers to cutting a wide roll or rolled product into products of the required width according to the actual needs. In the label production process, the content is first printed on the label paper using the printing device of the cross-cutting printing press. The printed label paper is then conveyed to the slitting device through the conveying device. The slitting device is then used to cut it and cut it to the size required for production. Nowadays, in order to improve the aesthetics of paper, people generally use printing presses to print some patterns on the paper to make it look more beautiful. When printing some papers, the original paper is generally in the form of a roll. During printing, the original paper is continuously unfolded and transported into the printing press for printing. After printing is completed, it generally needs to be cut into strips, so a slitting device is needed. Due to the strong practicality of this slitting device, it quickly gained widespread application and gradually gained people's favor.
