Description

Technical Field

[0001] The present application relates to the technical field of printing machines, and in particular to a slotting device for a printing machine. Background Art

[0002] For example, a slotting device for a printing machine mentioned in announcement number CN201820104100.2, a slotting mechanism for a printing machine, a printing slotting machine, also known as a water-based printing slotting machine, a carton printing slotting machine, a water-based printing slotting machine or a corrugated board printing slotting machine, is a comprehensive carton processing equipment that integrates five processes of printing, slotting, corner cutting, creasing and edge cutting. It is an indispensable post-processing equipment in the production of corrugated cartons. The current slotting mechanism does not have a good adjustment function, the tool holder cannot move and the distance between the tool holders cannot be adjusted as needed, so that the slotting distance cannot be better adjusted. Some slotting mechanisms that can adjust the distance need to measure the distance between the tool holders through external tools, which is more complicated to operate and is prone to errors in the measurement process, affecting the quality of the slotting;

[0003] The solution is to install the annular slotting blade on the guide roller through an annular slip ring, so that the blade can slide freely on the guide roller, so as to control the slotting distance. The distance between the slots can be controlled more accurately with the scale line, and the annular slip ring can be fixed by a locking bolt to prevent the annular slotting blade from shaking during slotting. Four sets of annular slotting blades are installed on the guide roller.

[0004] With respect to the above-mentioned related technologies, the inventor believes that in the current printing press technology, the blade of the slotting device needs to be replaced regularly to ensure the printing quality. The blade of the device is installed on the guide roller. Therefore, replacing the blade often takes a lot of time and the operation is complicated, which affects the production efficiency of the printing press. A method and device for replacing the blade of a slotting device for a printing press is needed to simplify the operation and improve the replacement efficiency.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
