Printing cutting machine with adjustable distance

Technical Field

The utility model discloses a printing splitting machine with adjustable spacing, and relates to the technical field of splitting machines.

Background

Slitting machines for printing are devices common in the printing industry for slitting large webs of printed material or continuous rolls of material to a desired size or length for subsequent processing or use. The cutting machine for printing plays a key role in the printing industry, can improve the production efficiency and the product quality, and simultaneously improves the flexibility and the diversity capacity of production.

When the splitting machine is used for processing, the position and the pressure of the blade can be adjusted according to the requirements so as to adapt to different materials and cutting requirements. The position of the blade is usually adjusted by using a tool (usually a wrench or a screwdriver), loosening the blade fixing screw, and after the position of the blade is adjusted, screwing the blade fixing screw again by using the tool to ensure that the blade is firmly fixed in position. This way of adjusting the blades is a relatively extensive way, which wastes more time, and therefore it is desirable to provide a pitch-adjustable slitting machine for printing to solve the above problems.
