Analysis of common faults of printing machinery

Printing machinery is an indispensable and important equipment in the modern printing industry. It undertakes the important task of accurately and efficiently transferring graphic information to the substrate. However, due to improper operation, aging equipment, inadequate maintenance and other reasons, printing machinery will inevitably experience various failures during use. This article will conduct an in-depth analysis of common faults of printing machinery and propose corresponding solutions in order to help printing companies better cope with and solve these problems.

First, let’s look at the possible failures of printing machinery during operation. This type of failure usually manifests itself as unstable mechanical operation, excessive noise, abnormal vibration, etc. There may be many reasons for this type of failure, such as weak equipment installation, worn bearings, poor gear meshing, etc. In order to solve these problems, printing companies need to regularly inspect and maintain the printing machinery to ensure that the equipment is installed in the correct position and the fastening bolts are tightened reliably. At the same time, wearing parts such as bearings and gears also need to be replaced in time to ensure the normal operation of the equipment.

In addition to operational failures, printing machinery may also suffer from print quality issues. This type of failure usually manifests itself as ghosting in printed matter, uneven ink color, blurred writing, etc. The occurrence of these problems is often related to factors such as printing plates, inks, and substrates. In order to solve these problems, printing companies need to select appropriate printing plates, inks and substrates, and make reasonable parameter settings according to printing requirements. At the same time, the printing plate needs to be cleaned and replaced regularly to ensure stable and reliable printing quality.

In addition, electrical failures may occur during the use of printing machinery. This type of failure usually manifests itself as the device being unable to start, no display on the display, control buttons malfunctioning, etc. The cause of this type of failure may be poor contact of the power line, damaged circuit board, sensor failure, etc. In order to solve this problem, printing companies need to regularly check the electrical system of the equipment to ensure that the power line connection is reliable and the circuit board is not damaged. At the same time, key components such as sensors also need to be regularly inspected and replaced to ensure the normal operation of the electrical system.

In addition to the above common faults, printing machinery may also have other uncommon faults that also affect normal production. For example, poor ink drying, paper transport failure, etc. In response to these failures, printing companies need to analyze and deal with them based on specific circumstances. For example, the problem of poor ink drying can be solved by adjusting the ink formula, adding drying equipment, etc.; for the problem of paper transmission failure, you can check the paper transmission mechanism, adjust the paper tension, etc. to troubleshoot and deal with it.

In the process of solving printing machinery failures, printing companies also need to pay attention to some details. For example, when repairing equipment, you must follow relevant safety regulations to ensure the personal safety of maintenance personnel; when replacing parts, you must choose accessories with reliable quality to avoid using inferior parts that lead to frequent equipment failures; when debugging equipment, make adjustments based on the actual situation , to avoid blindly adjusting parameters leading to equipment performance degradation.

To sum up, printing machinery will inevitably encounter various failures during use. In order to ensure the smooth progress of production, printing companies need to strengthen the maintenance and upkeep of equipment and find and deal with faults in a timely manner. At the same time, it is also necessary to strengthen employee training and education to improve employees' operating skills and maintenance levels. Only in this way can the stable operation and efficient production of printing machinery be ensured.
