Printing paper tape lateral vibration testing device and testing method

Abstract

The invention discloses a printing paper tape lateral vibration testing device comprising an upper ultrasonic sensor, a controller and a concentration controller connected in order; the controller isalso connected with a lower ultrasonic sensor; the controller is provided with a LCD, an indication lamp unit and an alarm. The printing paper tape lateral vibration testing device is stable in performance, reliable in operation, can accurately measure paper tape vibration displacements, and dual-probe detection can improve the system detection precision. The lateral vibration testing method can solve the roll web lateral vibration problems formed by machine vibrations in a high speed printing process, thus ensuring the paper table stable operation and accurate overprinting, improving productquality, reducing material waste, and obviously improving production efficiency.

AI Technical Summary

Problems solved by technology

[0005] (1) Most of the existing devices use a single sensor, which can only detect one side of the paper tape. When the edge of the paper tape is damaged or irregularly changed, it is easy to cause detection errors; for the paper tape in a high-speed motion state, the system accuracy is low. Hysteresis in detection; when a single sensor fails, the test setup does not work properly;

[0006] (2) The roll paper has different specifications, and there are differences in the size of the web. The existing testing device can only realize a single edge detection, centering detection or line detection. Very complex and almost impossible to implement;

[0007] (3) During the printing process, the transparency, gloss, and chroma of different paper tapes are different. The existing testing device can only identify materials with a certain range of transparency. When the working range is exceeded, the device is difficult to detect normally;

[0008] (4) The working environment in the printing workshop is poor, and the existing devices mostly use traditional sensors, which are greatly affected by environmental factors and are sensitive to ambient light and noise, which may easily cause instability in the working state of the device
