Abstract

The invention discloses a vertical type ultrasonic wave paper thickness measuring device. The vertical type ultrasonic wave paper thickness measuring device is characterized by comprising a paper bearing base, a tank body, an upper ultrasonic wave probe, a lower ultrasonic wave probe, an upper tank cover, a semi ball valve, a first electromagnet, a second electromagnet, a third electromagnet, frame supports, an upper frame support, a fixed pin and a sleeve. The whole vertical type ultrasonic wave paper thickness measuring device is of a vertical type frame structure, the upper portion, the lower portion, the left portion and the right portion of the vertical type ultrasonic wave paper thickness measuring device are connected into a whole through the upper frame support, the paper bearing base and the two frame supports, and baffles are not arranged on the front portion and the back portion. By means of the vertical type ultrasonic wave paper thickness measuring device, the ultrasonic wave distance measuring principle is used for conducting high-accuracy thickness measuring on paper on the paper bearing base, the traditional measuring mode that ultrasonic waves are propagated in air is converted into the mode that the ultrasonic waves are propagated in liquid, the transmitting frequency of the ultrasonic waves is improved, and the measuring accuracy is improved.

Description

technical field

[0001] The invention relates to the technical field of ultrasonic ranging, in particular to a vertical ultrasonic paper thickness measuring device. Background technique

[0002] Due to the rapid development of modern society, paper, as an irreplaceable consumer product, plays an extremely important role in business, education, military and other related aspects. Since there are many manufacturers of paper, each of them has different production methods and quality standards, which leads to different paper specifications. In the process of use and quality inspection, it often causes greater troubles. Especially for quality inspection agencies, due to the different specifications of different papers, it takes a lot of energy to check whether the paper is qualified and to distinguish the paper manufacturer, especially in the paper thickness inspection. Since paper is different from other thin objects such as steel plates, pipes, plates, etc., it cannot be detec...
