[0022] As shown in Figure 1 The side of storage tank 1 is equipped with viscosimeter 2, viscosimeter 2 is connected with tension sensor 7, receives the gravity change data of viscosity cup 10 transmitted by tension sensor 7 in real time, and obtains the viscosity of liquid in the tank by calculating the relationship between the weight reduction and time.

[0023] As shown in Figure 1 The side of storage tank 1 is equipped with ladder 3, the setting of ladder 3 is convenient for operator to climb to the top of storage tank 1, and carry out the operation such as placing and taking out viscosity cup 10.

[0027] The operator first starts the second motor 13, the second motor 13 drives the gear 14 to rotate, since the gear 14 is engaged with the rack 5, the rotation of the gear 14 lifts the bottom end of the rack 5 to the top end of the storage tank, after the second motor 13 runs for a preset time, the operator climbs up the top end of the storage tank 1 through the ladder 3, opens the opening and closing cover 15 of the resin storage tank 1, puts the viscosity cup 10 into the collar 11, then tightens the bolt 12 on one side of the collar 11, fixes the viscosity cup 10, to ensure that the viscosity cup 10 will not shake in the subsequent operation process.
