Description
Technical Field
[0001] This utility model relates to the field of printing equipment monitoring technology, specifically to a device for collecting sound and vibration signals of a printing press, which aims to realize real-time collection and analysis of sound and vibration signals during the operation of the printing press, so as to improve printing quality and equipment maintenance efficiency. Background Technology
[0002] With the continuous improvement of industrial automation, the printing industry's demand for monitoring equipment operating status is also increasing. Current methods for monitoring printing equipment operating status typically rely on manual inspection or simple alarm systems. While these provide some feedback on equipment status, their monitoring accuracy and response speed are far from meeting the demands of modern printing companies for high efficiency, precision, and intelligence. Especially when capturing subtle sounds and vibrations generated during printing press operation, problems exist such as long response times, insufficient signal acquisition accuracy, and the inability to provide real-time feedback on abnormal information. These limitations significantly reduce the accuracy and efficiency of fault diagnosis, and may even cause the best time for repairs to be missed, ultimately affecting production stability and product quality.
[0003] To meet the needs of modern printing companies, a more efficient, accurate, and intelligent equipment monitoring system is urgently needed. By collecting and analyzing the sound and vibration signals of the printing press during operation, the system can monitor the equipment status in real time without manual intervention, identify potential faults in advance, and provide high-precision fault diagnosis through intelligent analysis. This solution not only improves the stability of equipment operation but also significantly reduces downtime during production, thereby enhancing overall production efficiency and product quality. Utility Model Content

This device can comprehensively and in real-time collect and analyze sound and vibration signals during the operation of the printing press. It features strong anti-interference performance and convenient installation, and can be easily and quickly integrated into existing printing production lines, thereby providing strong data support for the maintenance of printing equipment.
[0005] The technical solution adopted in this utility model is to provide a device for acquiring sound and vibration signals from a printing press, including a vibration sensor module, a sound sensor and a vibration sensor module, a data acquisition module, and a data analysis module. The vibration sensor module is mounted on a wall panel near the printing plate cylinder to acquire vibration signals from the printing press. The sound sensor and vibration sensor module are mounted on the wall panel near the impression cylinder, enabling simultaneous acquisition of sound and vibration signals. The data acquisition module mainly consists of a data acquisition unit connected to the vibration sensor module, sound sensor, and vibration sensor module. It is responsible for receiving and processing the acquired sound and vibration signals in real time, and performing filtering and noise reduction operations. The data analysis module mainly consists of an industrial control computer used to display, store, and analyze the data transmitted by the data acquisition unit. It is equipped with a high-performance CPU, memory, storage devices, and various interfaces for connecting to external devices.
[0006] The present invention is further characterized in that,
[0007] Furthermore, the vibration sensor module includes multiple high-sensitivity vibration sensors, which are respectively attached to the side wall panels of the printing press via magnetic bases and positioned near the printing plate cylinder. The outer shell is made of ABS plastic (acrylonitrile-butadiene-styrene copolymer), a high-strength, high-toughness thermoplastic engineering plastic that effectively protects the vibration sensor module from external impacts and environmental influences; its excellent chemical corrosion resistance and electrical insulation make it suitable for long-term stable operation in industrial environments. The magnetic base uses high-performance magnetic materials, specifically neodymium iron boron (NdFeB) magnets, providing extremely strong adhesion. Even under high-intensity vibration and impact, it maintains tight contact with the wall panel, avoiding data acquisition errors caused by loosening. The NdFeB magnets also undergo surface coating treatments such as nickel plating to prevent magnet corrosion. A buffer layer, namely a silicone gasket, is added between the magnetic base and the vibration sensor module to absorb vibration energy and improve measurement accuracy and stability.

[0010] Furthermore, the data analysis module includes an industrial control computer, etc., for displaying, storing and analyzing the data transmitted by the data acquisition instrument, configuring high-performance CPU, memory, storage devices, etc., and equipped with multiple interfaces to connect to external devices.
[0011] The beneficial effects of this utility model are:
[0012] (1) By simultaneously collecting vibration and sound signals from the printing press, the operating status information of the printing press can be obtained from multiple dimensions. Vibration signals can reflect the mechanical operating condition of the printing press, such as wear and loosening of parts; sound signals can capture abnormal sounds that may occur during the printing process, such as foreign objects getting stuck or poor gear meshing. The dual signal detection mechanism makes the monitoring of the printing press's operating status more comprehensive and accurate, providing a richer data foundation for subsequent data analysis and fault diagnosis, helping to discover potential problems in a timely manner, reduce downtime due to faults, and improve production efficiency and product quality.
[0013] (2) The industrial control computer is equipped with high-performance hardware, which enables the rapid and efficient processing and analysis of a large number of sound and vibration signals transmitted by the data acquisition instrument, thereby realizing intelligent diagnosis and prediction of the printing press's operating status. By using a deep learning model to train the collected signal data, the normal operating status and various fault modes of the printing press can be automatically identified and classified, providing early warning of possible faults, providing a scientific basis for equipment maintenance, and reducing maintenance costs and risks.
[0014] (3) The vibration sensor module, sound sensor, and vibration sensor module all adopt a magnetic base structure. This structure design not only allows the sensor module to be firmly attached to the wall panel, but also ensures that the sensor is in close contact with the wall panel even in the high-intensity vibration and impact working environment of the printing press, avoiding data acquisition errors caused by loosening. It also takes into account the convenience of sensor installation and maintenance. The outer shell is made of ABS plastic (acrylonitrile-butadiene-styrene copolymer), which can effectively protect the sound sensor and vibration sensor module from external impact and environmental influence. The magnetic base is made of high-performance magnetic material, specifically neodymium iron boron (NdFeB) magnet, which provides extremely strong adhesion. Even under high-intensity vibration and impact, it can maintain close contact with the wall panel, avoiding data acquisition errors caused by loosening. The neodymium iron boron (NdFeB) magnet also needs to be treated with surface coatings such as nickel plating to prevent magnet corrosion. A buffer layer, namely a silicone pad, is added between the magnetic base and the sound sensor and vibration sensor module to absorb vibration energy and improve measurement accuracy and stability.
