Specifically, the worker presets in the display console 16 the data fluctuation time Sn between the start time at which the output voltage signal of the load cell 12 appears and the signal data steady state, when the liquid coating liquid bag is placed on the upper plate 15, the load cell 12 detects the weight of the liquid coating, and the display console 16 collects and analyzes the detected data and records the data fluctuation time S1 in real time.
When S1< Sn, it is explained that the data fluctuation time is short, the oscillation floating of the upper plate 15 is small.
When S1> Sn, it is indicated that the data fluctuation time is longer, the oscillation floating of the upper plate 15 is large, in the state that the data fluctuation time is longer, the upper plate 15 is affected by the impact force to drive the pressure point 14 to move down, the jacking cylinder 22 pushes the top frame 23 to move up, the top frame 23 pulls the two buffer springs 281 and the stand column 291 to move up, and the top frame 23 carries out limit guiding through the two guide posts 282, so that the top frame 23 keeps a horizontal state, at this time, the buffer springs 281 are elongated, the stand column 291 drives the piston 295 to move up in the vertical tube 292, the space of the inner cavity of the vertical tube 292 is increased, the external air enters the cavity through the air inlet valve 294 with a larger pipeline diameter, and at the same time, the top frame 23 pushes the two fixing seats 24 and the connecting blocks 25, the support rods 26 and the positioning blocks 27 corresponding to the fixing seats 24 to move up, the top surfaces of the two positioning blocks 27 are attached to the bottom surfaces of the upper plate 15 to complete auxiliary supporting, and the weighing accuracy is avoided from being affected by the impact force repeated fluctuation.
When the positioning block 27 completes the auxiliary support of the upper plate 15 once, the piston rod of the jacking cylinder 22 is completely contracted to be separated from the top frame 23, at this time, the top frame 23 is moved downwards under the influence of the reset elastic force of the buffer spring 281, the top frame 23 pushes the stand column 291 and the piston 295 to move downwards in the vertical pipe 292, at this time, the chamber space is reduced, however, due to the smaller pipe diameter of the exhaust valve 293, the air exhausting speed in the chamber is slower, so that the top frame 23 moves downwards slowly, in the process, the positioning block 27 supports the upper plate 15 in an auxiliary manner, when the upper plate 15 moves downwards to generate pressure to the pressure point 14, the pressure point 14 supports and blocks the upper plate 15, and due to the slow release of the upper plate 15 from top to bottom, the vibration amplitude of the upper plate 15 is reduced, and the upper plate 15 presses the pressure point 14, and the pressure point 14 applies pressure to the weighing sensor 12, thereby completing the weighing of the liquid paint.
