Analysis of common faults in printing equipment

As the core equipment of the modern printing industry, printing machinery is crucial to ensuring production efficiency and product quality. However, in the face of multiple possible failures, how printing companies can effectively deal with and solve problems has become a topic that needs to be discussed urgently. The following is an in-depth analysis of common faults and solutions for printing machinery, aiming to provide valuable reference for printing companies.
1. Mechanical operation failure and solution
failure manifestations: unstable mechanical operation, excessive noise, abnormal vibration, etc.
Cause analysis:
The equipment is not installed firmly, causing it to shake during operation.
Bearing wear affects rotational accuracy.
The gears are poorly meshed, causing noise and vibration.

Solutions:
Regular inspection and maintenance: Establish a regular maintenance system to ensure the correct installation position of the equipment and the reliable tightening of the fastening bolts.
Replace consumable parts: replace worn bearings and gears in time to maintain the operation accuracy of the equipment.
Lubrication maintenance: Lubricate the equipment regularly to reduce friction and wear.
2. Print quality problems and solutions
for fault manifestations: prints have ghost images, uneven ink colors, blurred handwriting, etc.
Cause analysis:
Printing plate is worn or improperly installed.
Ink formula or viscosity is not appropriate.
The surface of the printing material is uneven or has poor ink absorbency.
Solution:
Select the right printing plate, ink and substrate: Select the right material according to the printing requirements.
Parameter settings: Reasonably set printing parameters, such as pressure, speed, ink volume, etc.
Printing plate cleaning and replacement: Clean the plate regularly and replace the printed plate with severe wear in time.

3. Electrical failure and resolution measures
: The equipment cannot be started, the display screen has no display, the control button fails, etc.
Cause analysis:
Poor contact of power lines.
The circuit board is damaged.
Sensor failure.
Solution:
Electrical system inspection: Check the power supply lines regularly to ensure reliable connection.
Circuit board detection and replacement: Use professional tools to detect circuit boards and replace damaged circuit boards in time.
Sensor Inspection and Calibration: Check and calibrate the sensor regularly to ensure it is working properly.
4. Other common faults and solutions
: poor ink drying, paper transmission failure, etc.
Cause analysis:
Incorrect ink formula or drying conditions.
The paper conveyor mechanism is worn or improperly adjusted.
Solution:
Ink formula adjustment: Adjust the ink formula according to the printing materials and requirements, and add drying equipment.
Paper transfer mechanism inspection: Check the paper transfer mechanism, adjust the paper tension, and ensure smooth paper transfer.
5. Precautions
In the process of solving printing machinery failures, printing companies also need to pay attention to the following details:
Safety regulations: When repairing equipment, relevant safety regulations must be followed to ensure the personal safety of maintenance personnel.
Accessories quality: When replacing parts, choose reliable quality accessories to avoid frequent equipment failures caused by using inferior accessories.
Debugging parameters: When debugging the equipment, adjust it according to the actual situation to avoid blindly adjusting the parameters and causing equipment performance to decline.
6. Summary:
Various failures are inevitable during the use of printing machinery, but as long as the printing company strengthens the maintenance and maintenance of equipment and promptly detects and handles faults, it can ensure the smooth progress of production. At the same time, strengthening employee training and education and improving employee operating skills and maintenance levels is also the key to ensuring stable operation and efficient production of printing machinery. By continuously optimizing equipment management and maintenance processes, printing companies can maintain a leading position in the fierce market competition.
