Description

Technical Field

[0001] This utility model belongs to the field of printing equipment technology and discloses a printing machine electrostatic detection system. Background Technology

[0002] In the modern printing industry, static electricity is easily generated on printing paper during the printing process due to friction and other factors. This static electricity can adversely affect print quality, specifically manifesting as paper sticking, blurred printed patterns, and potential paper wrinkling during subsequent winding. Therefore, effectively monitoring and eliminating static electricity during the printing process has become an important issue for improving print quality.

[0003] In existing technologies, static electricity generation is typically reduced by installing static eliminators at different locations on the printing press. However, these devices are mostly passive static eliminators, capable of eliminating static electricity only when it has already affected print quality. They lack real-time static electricity monitoring capabilities and cannot prevent static electricity problems in advance. Therefore, the drawback of untimely static electricity detection and control persists, making it difficult to guarantee the quality of printed paper.

[0004] On the other hand, existing electrostatic discharge (ESD) detection equipment also has certain limitations in installation and use. For example, some ESD detection devices cannot be flexibly adjusted according to the working state of different parts of the printing press, resulting in poor accuracy and versatility. In addition, most existing detection systems operate independently and lack effective linkage with the overall control system of the printing press, leading to untimely information transmission and making it difficult to achieve real-time monitoring and management of the overall operating status of the printing press. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a printing machine electrostatic detection system.

[0006] The technical solution provided by this utility model is as follows:

[0007] A printing press electrostatic detection system includes a printing press, a plurality of electrostatic detection devices installed on the printing press, and a signal line collection box installed on the printing press.

[0008] The detection end of the electrostatic detection device faces the printing paper. The signal cable collection box contains a printing press serial port server. The data collected by the electrostatic detection device is transmitted to the printing press computer terminal through the printing press serial port server. The printing press computer terminal is connected to the central control terminal, which is used to control the operation of the system.

[0009] In some embodiments, the electrostatic detection device includes a crossbar mounted on the frame of the printing press, with an electrostatic sensor located at the center of the crossbar.

[0010] In some embodiments, a fixed base is provided in the middle of the crossbar, and the electrostatic sensor is axially connected to the fixed base.

[0011] In some implementations, the electrostatic sensor is located between two conveyor rollers on the printing press. In other implementations, the printing press computer terminal is connected to the central control unit via a switch.

[0012] In some implementations, the central control unit is connected to the display unit, which is a dashboard that displays the system's operating status.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] (1) This utility model can detect the static state of the printing paper surface in real time by setting an electrostatic detection device between the two conveyor rollers of the printing machine, so as to prevent the static electricity on the printing paper surface from affecting the printing and winding quality of the printing paper.

[0015] (2) This utility model sets the electrostatic sensor to be adjustable in angle. By connecting the electrostatic sensor shaft to the fixed base, the detection angle of the electrostatic sensor can be adjusted over a wider range. The angle of the electrostatic sensor can be adjusted according to the conveying angle of the printing paper at different positions, which improves the versatility and accuracy of detection.

It is located in the factory display area or the office area, so that the staff can see the operating status of the printing machine at any time and troubleshoot the fault at any time, thereby improving the printing quality.
