7) rollover stand cylinder promotes rollover stand and falls to the vacuum that vacuum takes out material system and take out on the end face of batch can, and the end face taking out batch can with vacuum is combined closely;
8) start vacuum and take out material system, clear up slurry unnecessary in honeycomb substrate duct by vacuum pump system;
9) rollover stand again promotes under rollover stand cylinder action, and the honeycomb substrate that the clamping of flexible clamping air bag has applied half to move upset 180 ° with rollover stand;
10) vacuum (-tight) housing moves down under vacuum (-tight) housing cylinder action, and is pressed on the upper surface of rollover stand, ensures contact end face seal;
11) slurry dish pushes to immediately below rollover stand by slurry automatic conveying system, and centering is located;
12) rollover stand cylinder promotes rollover stand and falls to slurry liquid level appropriate location to immerse slurry, and the vacuum (-tight) housing be connected with vacuum pump system starts to vacuumize, and the slurry of extraction is through honeycomb substrate duct and evenly apply second half of honeycomb substrate;
13) rollover stand upwards promotes under rollover stand cylinder action, and slurry automatic conveying system regains slurry dish, and vacuum (-tight) housing upwards promotes under vacuum (-tight) housing cylinder action, departs from the upper surface of rollover stand;
14) rollover stand cylinder promotes rollover stand and falls to the vacuum that vacuum takes out material system and take out on the end face of batch can, and combines closely with the end face that vacuum takes out batch can;
15) start vacuum and take out material system, clear up slurry unnecessary in honeycomb substrate duct by vacuum pump system;
16) rollover stand again promotes under rollover stand cylinder action, honeycomb substrate automatic conveying system moves to immediately below rollover stand system, rollover stand falls, flexible clamping air bags, coated honeycomb substrate drop on the honeycomb substrate frame of honeycomb substrate automatic conveying system under gravity;
17) rollover stand promotes under rollover stand cylinder action, and coated honeycomb substrate is sent by honeycomb substrate automatic conveying system, completes the coating of honeycomb substrate Double End;
Repeat above-mentioned steps 1) ~ 17), going round and beginning again, is namely the pattern of working continuously.
