The operation principle and workflow of the utility model array-type ultrasonic sheet thickness measuring device be：The device group
After the completion of dress, by breather pipe 3, into tank body, liquid feeding body, liquid to be filled it up with afterwards are sealed two passages 22 with plug.
In off working state, electromagnet 610 is powered off, and the spring 69 between steady pin 611 and stop pin 68, which is in, slightly to be compressed
State, measurement end face 612 is with holding paper 5 a distance away.
During start-up operation, it is divided into two stages.First stage, hold when not putting paper on paper 5, control electromagnet 610 is logical
Electricity, due to the effect of steady pin 611 so that right cylindrical tube 66 along chute 615 to moving close to holding the direction of paper 5 so that
Measurement end face 612 is in close contact with holding paper 5.Now, ultrasonic wave transmitting probe 61 launches a number of pulse (5), warp
Ultrasonic wave receiving transducer 62 receives, and takes the 3rd pulse to measure distance measure as measurement pulse.Complete data after measuring
Storage, control electromagnet 610 powers off, and in the presence of the reaction force of spring 69, right cylindrical tube 66 returns to original position, measures end face
612 separate with holding paper 5.To avoid interfering between ultrasonic wave, control and first piston hole 211, the 3rd piston hole first
213rd, the 5th piston hole 215, the 7th piston hole 217 and the corresponding measuring mechanism of the 9th piston hole 219 complete above-mentioned action, treat
