The cantilever 23 can move under the drive of the cantilever bracket 24, the first-stage motor 27 is started, the cantilever bracket 24 moves up and down along the first-stage lead screw 25 and the slide bar 26 under the drive of the first-stage motor 27, when the cantilever 23 reaches the position which is in the same horizontal plane with the drying disc 19 to be fed, the cantilever 23 pushes the pulley 58, the locking mechanism 17 is started, the second-stage shaftless cylinder 31 drives the telescopic arm 32 to do stretching motion, the telescopic arm 32 moves to the lower part of the drying disc 19, the electromagnet on the telescopic arm 32 is started, the second-stage shaftless cylinder 31 drives the telescopic arm 32 to do shrinking motion, the drying disc 19 is moved to the cantilever 23, the cantilever 23 moves upwards to the highest position under the drive of the cantilever bracket 24, at the moment, the material to be dried enters the drying disc 19 through the feed inlet 4, the cantilever 23 moves downwards to the previous position under the drive of the cantilever bracket 24, the second-stage shaftless cylinder 31 drives the telescopic arm 32 to do stretching motion, the electromagnet on the telescopic arm 32 is closed, the drying disc 19 moves to the position, the drying disc 19 is locked by the second-stage shaftless cylinder 31 and the pneumatic interface 18 is locked by the pneumatic interface 18 (the pneumatic interface is locked by the pneumatic interface 18 is locked by the telescopic arm 32) as shown in figure 11). The cantilever 23 repeats the above operation and the taking and depositing drying trays 19 are circulated until all the drying trays 19 are filled with material. The locking mechanism 17 works on the following principle (as shown in fig. 14): when the pulley 58 is pushed to the right under the action of external force, the pulley 58 pushes the cross arm 59 to move to the right along the cross rod 67, the primary gear 61 is driven to rotate clockwise while the primary gear 60 moves to the right, the secondary gear 62 also drives the secondary gear 64 to move downwards while rotating clockwise, so that the vertical arm 63 is driven to move downwards along the vertical rod 68, the vertical arm 63 is separated from the jack 80, the locking mechanism 17 is in an unlocking state, and when no external force acts on the pulley 58, the cross arm 59 moves to the left under the action of the spring 66, the vertical arm moves upwards, and the locking mechanism 17 is in a locking state.

Cantilever return (as shown in fig. 3): after the material fills each drying tray 19 and the trays are in place, the cantilever arms 23 are raised to the highest point (return).

Expanding a primary drying tray bracket; after the cantilever is returned, the first-stage drying tray support 11 slides leftwards along the sliding rail 9 by the first-stage shaftless cylinder 10 through the connecting rod 14, and the drying trays 19 placed on the first-stage drying tray support 11 leave the second-stage drying tray support 12 (shown in fig. 1) through the action, so that enough drying space is reserved between the drying trays 19 for evaporating and drying the solvent.

And (3) drying: when the primary drying tray support 11 is unfolded, the vacuum pump is externally connected to the vacuum interface 5 to vacuumize the box body 1, and steam is externally connected to the steam interface 75 to convey steam to the compressed air pipeline 74 in the box body 1, so that each drying tray 19 is heated.
