During the printing process, the stable operation of the printing press is crucial to ensuring print quality. However, the high-speed operation of the printing press is often accompanied by equipment vibration, temperature changes, and fluctuations in environmental conditions, all of which can adversely affect the performance and lifespan of the printing press. In particular, the normal operation of the centrifugal fan plays a vital role in ensuring ventilation, heat dissipation, and drying efficiency within the printing press. If the centrifugal fan malfunctions, such as insufficient oil level, excessive bearing vibration, or abnormally high temperature, it can lead to printing press failures or even shutdowns, thereby affecting production efficiency.

[0028] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0029] like Figure 1-6 As shown, a printing press ventilation detection system includes a printing press 1, a fan detection terminal, a printing press detection terminal, a switch, a serial port server, and a central control terminal. The central control terminal is connected to the switch to control the operation of the system. The printing press 1 is equipped with a frame 2 and a centrifugal fan 3.

[0030] The fan detection terminal is installed on centrifugal fan 3 to collect oil level, vibration, and temperature data at centrifugal fan 3. The printing machine detection terminal is installed on the frame to collect environmental data at frame 2. The central control unit aggregates the data from each printing machine, sets normal data values, and allows operators to promptly inspect and repair the printing machine when the data exceeds the normal values, thus preventing safety accidents.

[0031] The fan detection terminal and the printer detection terminal transmit the detected data to the switch via a serial port server.

[0032] The switch is used to forward data from the serial port server to the central control unit. The central control unit is used to control the operation of the system. It is responsible for integrating, processing, and finally displaying the data.

[0033] This invention utilizes a fan detection terminal mounted on the centrifugal fan and a printing press detection terminal mounted on the frame. This system can collect data on oil level, vibration, and temperature at the centrifugal fan, as well as environmental data at the frame, thereby enabling data monitoring of the printing press's ventilation system. By transmitting the data to a central control unit, the operating status of the equipment can be monitored promptly, allowing for the prevention and handling of abnormal situations.

[0034] In a preferred embodiment, the fan detection end includes a first sensor 5 disposed on the bearing housing 4 of the centrifugal fan 3, with the probe of the first sensor 5 extending into the bearing housing 4. A through hole 6 is formed at the bottom of the bearing housing 4, and a first step 7 and a second step 8 are formed from top to bottom within the through hole 6. The diameter of the first step 7 is smaller than the diameter of the second step 8. The first sensor 5 is fitted into the through hole 6, and the probe of the first sensor 5 extends into the bearing housing 4 through the through hole 6.

[0035] Specifically, in order to accurately measure the operating conditions inside the centrifugal fan 3, in this embodiment, the probe of the first sensor 5 is inserted into the bearing housing 4, and the first step 7 and the second step 8 are set to fully engage with the first sensor 5 to ensure the sealing of the bearing housing 4 and prevent oil or temperature inside the bearing housing 4 from being transmitted out through the through hole 6, thereby improving the accuracy of monitoring.

[0036] Furthermore, the inner wall of the vertical wall between the first step 7 and the second step 8 is threaded, allowing the first sensor 5 to be detachably mounted on the bearing seat 4 via the thread. This facilitates the disassembly and maintenance of the first sensor 5 by personnel and improves the durability of the device system.

[0037] The printing press detection end includes a second sensor 9 fixed to the side wall of the frame 2. An L-shaped mounting base 10 is fixed to the side wall of the frame 2, and the second sensor 9 is fixed to the mounting base 10. The second sensor 9 is typically fixed at the inlet and outlet of the centrifugal fan 3.

[0038] The L-shaped mounting base 10 allows the second sensor 9 to be stably mounted on the side wall of the frame 2. Depending on the size of the printing press 1, several second sensors 9 can be installed. The second sensor 9 is used to detect the temperature, humidity, noise, etc. around the printing press, and can more comprehensively measure the environmental data around the printing press, thereby achieving comprehensive monitoring of the printing environment and ensuring printing quality.

[0039] As a further optimized implementation method, the central control terminal is connected to the display terminal, which is a dashboard that displays the system's operating status.

[0040] The display board is used to show the operating status of various components of the printing press. It can be located in the factory display area or the office area, so that staff can see the status of each detection terminal at any time. Operators can promptly inspect and maintain the printing press based on the data from the ventilation system to avoid safety accidents.
