Example 2
A method for detecting running and breakage of an adhesive tape adopts the device of the embodiment 1 and comprises the following specific steps:
1) starting the adhesive tape machine and the detection device, wherein a pneumatic trigger unit of the device stably outputs an adhesive tape operation signal to an upper computer, and the upper computer identifies the normal operation of the adhesive tape machine;
2) when the tape running signal disappears, the upper computer still receives the running signal of the motor of the tape machine and does not receive the tape running signal for more than 60 seconds, and the tape is judged to be broken or completely slipped.
The working principle of the device is as follows:
1) under the action of the tensioning spring, the movable arm drives the driven friction wheel to fully contact the adhesive tape for friction transmission, and the phenomenon that the driven friction wheel loses rotation due to the vibration of the adhesive tape in the movement process of the adhesive tape is avoided because the tensioning spring is always in a tensioned state; the driven friction wheel drives the transmission shaft to rotate, the transmission shaft drives the large gear to rotate, the large gear drives the small gear to rotate, the small gear drives the main shaft of the blower to rotate, the gas under pressure generated by the blower enters the pressure-bearing cylinder through the reducing hose, and under the action of pressure, the gas pushes the pressure-bearing sliding plate to compress the pressure-bearing reset spring and drives the insulating pad and the trigger ring on the surface of the pressure-bearing sliding plate to slide towards the bottom surface b direction of the pressure-bearing cylinder along the inner wall; when the trigger ring of the pressure-bearing sliding plate is contacted with the trigger ring on the surface of the driven sliding ring, the rubber belt operation signal is started to be output and sent to the upper computer, the gas continuously pushes the pressure-bearing sliding plate and the driven sliding ring to respectively compress the pressure-bearing reset spring and the compression buffer spring to slide towards the direction of the pressure-bearing cylinder cover along the inner wall of the pressure-bearing cylinder until the gas pressure in the pressure-bearing cylinder is balanced with the acting force of the pressure-bearing reset spring and the compression buffer spring, the pressure-bearing sliding plate and the driven sliding ring are stable and do not move any more, and the trigger ring on the side of the pressure-bearing sliding plate can be always kept contacted with the trigger ring on the side of the driven sliding ring under the stress action of the compression buffer spring, even if the air pressure of the pressure-bearing cylinder is changed due to the change of the rubber belt operation speed, the full contact between, the upper computer identifies that the adhesive tape machine is in normal operation;
furthermore, when the running speed of the adhesive tape is high and the pressure of air of the blower entering the pressure-bearing cylinder is high, the pressure-bearing sliding plate and the driven sliding ring can slide through part of the exhaust holes, the pressure of the air in the pressure-bearing cylinder begins to be released, and the more the exhaust holes the sealing ring moves, the larger the amount of the exhausted air is until the pressure of the air in the pressure-bearing cylinder is balanced with the acting forces of the pressure-bearing reset spring and the compression buffer spring;
2) when the adhesive tape stops running, the driven friction wheel, the transmission shaft, the large gear, the small gear and the air blower stop rotating, the air pressure at the outlet of the air blower disappears, the pressure-bearing reset spring and the compression buffer spring respectively push the pressure-bearing sliding plate and the driven sliding ring to slide along the reverse direction of the inner wall of the pressure-bearing cylinder, the trigger ring at the side of the pressure-bearing sliding plate is separated from the trigger ring at the side of the driven sliding ring under the action of the pressure-bearing reset spring, the running signal of the adhesive tape disappears, and when the upper computer receives the running signal of the motor of the adhesive tape machine and does not receive the running signal of the adhesive tape.
