A cutting knife is one of the essential equipment in a printing press, its function is to handle the cutting of paper before and after printing. With the development of science and technology, paper cutting machines have more and more functions, simpler operations, lower labor intensity, high cutting accuracy, and safety. During use, the following problems often occur. Next, taking the digital display Paper Cuttings machine as an example, this paper briefly analyzes the reasons why the lower digital paper cutting machine is easy to break.

1. The blade is not sharp enough.

2. The sliding blocks on the left and right sides of the tool rack are worn.

The Development Status and Prospects of Paper Cutting Machines in China

3. Do not frequently tighten safety screws.

The installation direction of the safety screw is incorrect.

5. Due to deformation, the two ends of the connecting safety screws are uneven.

6. The cutting edge cuts too deep into the cutting edge, or the grinding of the cutting edge is not straight.

In addition to the above reasons, there are also electrical and other reasons. The faults of the paper cutting machine should be resolved in a timely manner to avoid delaying normal production work.

The operation interface (operation mode) of the programmable paper cutting machine can be divided into three modes: buttons, touch screen, keystroke, and touch screen.

The program-controlled Paper Cuttings machine operated by keys is Zui's earliest. It improves the twice efficiency of the digital Paper Cuttings machine, improves the working efficiency of many users, creates more wealth, and is favored by customers. However, after the advent of new technology, this way cannot be compared with the touch screen operation in an intuitive and simple way.

The touch screen operation mode can conveniently achieve functions such as equal division, equal spacing, loop size, calculator usage, and calculation result input program. The operation is simple and intuitive (key operation mode requires multiple key combinations to perform certain functions, and many users cannot find manuals to consult manufacturers for usage methods due to the operator's inability to find manuals). On the screen, the switch status of each operating link on the machine can be visually displayed, providing great convenience for troubleshooting common faults and saving time and cost for users and paper cutting machine manufacturers.
