Description

Technical Field

[0001] This utility model relates to the field of printing equipment testing technology, and belongs to a fault detection device for decorative paper printing production line. Background Technology

[0002] In the decorative paper printing industry, the continuous and stable operation of the production line is crucial. Currently, traditional decorative paper printing production lines mostly rely on manual inspections to detect faults, which has many drawbacks. On the one hand, the frequency of manual inspections is limited, making it difficult to capture early signs of sudden faults in real time. Often, faults are only discovered when they have already significantly impacted production efficiency or even caused a large number of products to be scrapped. On the other hand, manual inspection is limited by factors such as the experience, skill level, and fatigue of the inspectors, making it easy to miss or misjudge some complex and hidden faults. Moreover, with the increasing complexity of decorative paper printing processes, involving multiple stages such as multi-color printing, high-precision registration, and special texture printing, the mechanical structure and electrical control system of the production line are becoming increasingly sophisticated. If a fault occurs in any stage and cannot be located and repaired in time, it will result in huge economic losses. In addition, while some existing general-purpose industrial inspection equipment can detect some common faults, it lacks specific detection methods for faults unique to decorative paper printing production lines, such as ink color deviation, abnormal clarity of printed patterns, and unstable paper tension, failing to meet the industry's refined requirements. Therefore, there is an urgent need for a fault detection device for decorative paper printing production lines. Utility Model Content

The pressure sensor 31 is installed on the paper transport path and the temperature sensor 32 is distributed around the drying unit.

[0028] Alarm module 4 is electrically connected to the detection host 1. When the central processing unit 11 determines that there is a fault in the production line based on the collected data, it drives alarm module 4 to issue an audible and visual alarm signal.

[0029] The wireless communication module 5, integrated into the detection host 1, is used to transmit fault information to the remote monitoring terminal in real time, so that technicians can understand the status of the production line and make preliminary diagnoses in a timely manner.

[0030] Furthermore, the adjustable mounting bracket 22 includes a universal joint 23 and a telescopic rod 24. The universal joint 23 includes a support frame 231 and a steering platform 232. The support frame 231 is connected to the output end of the telescopic rod 24. The high-definition camera 21 is connected to the steering platform 232. A first connecting shaft 233 and a second connecting shaft 234 are connected to the steering platform 232. Both ends of the first connecting shaft 233 are provided with inclined connecting plates 235. The other end of the inclined connecting plate 235 is connected to a first adapter shaft 236.

[0031] Furthermore, the support frame 231 is provided with adapters 239 at both ends and in the middle. The first adapter shaft 236 is rotatably connected to the adapters 239 at both ends through shaft holes, and the second adapter shaft 238 is rotatably connected to the adapter 239 in the middle through shaft holes.

[0037] Working principle of this utility model:

[0038] During installation, first, fix the high-definition camera 21 of the image acquisition module 2 to a key part of the decorative paper printing production line using the adjustable mounting bracket 22. Adjust the shooting angle using the universal joint 23 and determine the appropriate height using the telescopic rod 24 to ensure comprehensive and clear image acquisition of all parts. Install the pressure sensor 31 of the sensor group 3 onto the paper transport path, and place the temperature sensor 32 in a suitable position inside and around the drying unit. Connect each module to the data interface 13 of the detection host 1 via a data cable, and then turn on the detection host 1.

[0039] During production line operation, high-definition camera 21 collects image information in real time and transmits it to the detection host 1 via data cable. Pressure sensor 31 and temperature sensor 32 in sensor group 3 monitor paper tension and drying temperature in real time, respectively, and transmit the data to the detection host 1. The central processing unit 11 within the detection host 1 analyzes and processes the collected data based on the fault diagnosis algorithm stored in memory 12. Once a fault is detected in the production line, the alarm module 4 immediately activates an audible and visual alarm signal with a corresponding frequency and color combination. Simultaneously, the fault information is transmitted to the remote monitoring terminal via wireless communication module 5. On-site operators can visually view the images, data, and fault diagnosis results on the external display screen 14 of the detection host 1, allowing for rapid response measures to ensure the normal operation of the production line.
