Problems solved by technology
[0003] In the process of paper production, paper mills often have quality problems such as paper breakage and cracks during the transmission process. The root cause is that the pulp output speed does not match the speed of the paper during the transmission process, and the transmission speed is too slow. Paper stacks are prone to creases, and the transmission speed is too fast, and the paper is easy to be torn
Most of the traditional testing equipment is used to test the production quality of paper. Once there are quality problems such as cracks and paper breaks, it is generally necessary to manually stop the machine to adjust the operating parameters of the equipment or rectify the equipment. However, this will affect the continuity of production and cannot be automatically implemented. Optimal adjustment of equipment operating parameters to reduce problems such as breakage during paper production

Embodiment Construction
[0027] The structures involved in the present invention or the technical terms used are further described below. These descriptions are only used as examples to illustrate how the present invention is implemented, and do not constitute any limitation to the present invention.
[0028] An automatic monitoring system for preventing paper breakage, including a processor and a camera installed on a paper machine production line, the camera at least includes an upper camera 141 for capturing images of the upper surface of the paper, and a side camera 142 for capturing the thickness of the side of the paper, and the image acquired by the camera is input and processed In the processor, the processor 13 performs the following operations: make the camera capture the paper image in real time, and record the motor speed and torque for conveying the paper at the corresponding moment; identify the paper surface image captured by the upper camera 141, and judge whether there is a crack on th...

The invention discloses a paper monitoring automatic anti-breaking system, which can automatically monitor the running state of the paper and collect the paper surface image and paper side image information during the paper transmission process in real time, and automatically judge the running state of the paper machine through the paper image information. Adjust the operating parameters of the equipment in real time to prevent quality problems such as paper breaks during the paper transmission process, and effectively improve the production efficiency and production quality of the papermaking equipment.
Description
technical field [0001] The invention relates to the field of detection of paper quality and automatic control of equipment in the paper production process of a paper mill, in particular to a paper monitoring automatic anti-breaking system. Background technique [0002] The following background art is provided to help the reader understand the present invention and is not to be admitted as prior art. [0003] In the process of paper production in paper mills, quality problems such as paper breakage and cracks often occur during the transmission process. The root cause is that the matching degree between the pulp output speed and the transmission paper speed during the transmission process is not coordinated, and the transmission speed is too slow. Paper stacks are prone to creases, and the transport speed is too fast, and the paper is easy to be torn. Most of the traditional testing equipment is used to test the production quality of the paper. Once there are quality problem...
