Background
The paper pulp molding is a three-dimensional papermaking technology, which takes plant fiber as raw material, and uses a mold with a specific shape to retain paper pulp on the surface of the mold through a suction filtration process on a paper pulp molding machine, thereby molding a paper packaging product with a specific shape. In the process of pulp molding production and forming, the forming die needs to do up-and-down reciprocating motion in the pulp tank so as to facilitate pulp suction and shaping; the key of the production of the pulp molding product lies in the molding process, which can directly affect the product quality. The vacuum suction filtration forming means that the equipment is vacuumized (the vacuum degree is about-0.07 MPa) to enable the fibers to be adsorbed on the filter screen, and water is pumped away and discharged through the vacuum tube, so that the uniformity of the pulp fibers in the pulp tank determines the uniformity of the fibers left on the filter screen.

Assume that the density of the slurry in the stock chest 13 ρ =3g/cm 3 (ii) a Volume V =0.15m of stock chest 13 3 (ii) a The operating time of the converter 5T =120s; the product λ =0.85 of the precision coefficients of the density sensor and the timer; the cross-sectional area S =0.1m of the slurry in the slurry tank 13 2 (ii) a Unit time t =10s; natural constant e =2.72; dynamic viscosity of slurry eta =1.5n × s/m 2 (ii) a The mixing index K =35.6 of the pulp in the stock chest 13 can be calculated as described above, and if the mixing index of the corresponding preset pulp is 20, the alarm does not give an alarm.
The working principle and the beneficial effects of the calculation scheme are as follows: the mixing index of the slurry in the slurry tank 13 is calculated by using the formula (1), the controller compares the mixing index of the slurry in the slurry tank 13 calculated by the formula (1) with the corresponding mixing index of the preset slurry, and when the mixing index of the slurry in the slurry tank 13 calculated by the formula (1) is smaller than the corresponding mixing index 20 of the preset slurry, the controller controls the alarm to give an alarm to prompt personnel that the slurry is mixed and has a problem, so that the working conditions of the ultrasonic starter 4 and the converter 5 need to be detected in time. When maintenance or replacement is completed, the ultrasonic actuator 4 and the transducer 5 are re-operated, and the controller switches on the density sensor, the timer and the alarm to predict the mixing index of the slurry in the slurry tank 13. And realize reporting to the police and remind personnel to inspect the condition of ultrasonic starter 4 and converter 5 through setting up the alarm, effectively promote the functional of device.
