When in use, the method comprises the following steps:
step 100, the roller driving mechanism 4 is started, so that the motor of the roller driving mechanism 4 drives the roller 1 to rotate through the belt.
The left side of the roller 1 is provided with an inner air drying mechanism 5 and a powder raising mechanism 7 through a torsion energy storage ring 12 and a multiple butt joint rotating ring 13 on the right side, two ends of the roller 1 are respectively supported and rotatably connected with the driving roller seat 2 and the driven roller seat 3 through outer bearing rings 11, and when the roller driving mechanism 4 drives the roller 1 to rotate, relevant mechanisms in the inner air drying mechanism 5 and the powder raising mechanism 7 cannot be driven to rotate.
Step 200, powder is poured into a feeding funnel 134 arranged on a driven roller seat 3 and enters the interior of the roller 1 through the feeding funnel 134, and the powder pushing convex strips 6 on the inner side of the roller 1 drive the accumulated powder to gradually turn over towards the other end of the roller 1 along with the rotation of the roller 1.
Step 300, starting the hot air blower 52 of the air drying mechanism 5 in the drum, discharging the outside air into the air pipe 51 through the hot air blower 52, and uniformly blowing out the outside air into the drum 1 in all directions through a plurality of air outlet nozzles 53 which are spirally distributed on the outer side of the air pipe 51.
Because the powder accumulated in the roller 1 is continuously driven by the powder pushing convex strips 6 to rise to a high position by a small amount under the action of the rotation of the roller 1 and naturally falls down at the high position, the air pipe 51 for air outlet is arranged on the central axis of the roller 1 and is exhausted by a plurality of air outlet nozzles 53 which are arranged on the outer side of the air pipe and distributed in a spiral shape, so that the naturally falling powder and the powder accumulated at the bottom of the roller 1 are continuously dried by the air flow discharged by the hot air blower 52.
Step 400, the powder is blown dry by the air drying mechanism 5 in the roller for one time in the process of turning and falling, naturally falls and is accumulated on the powder raising mechanism 7, then the powder is raised elastically at intervals by the powder raising mechanism 7, and the powder is blown dry for the second time by matching with the air drying mechanism 5 in the roller.
In the process that powder which moves to a high position along with the rotation of the roller 1 and naturally falls is dried by the air drying mechanism 5 in the roller, the powder can be driven to move along the side wall of the roller 1 and fall onto the material turning plate 72 of the powder raising mechanism 7, the tooth socket barrel 71 connected with one end of the material turning plate 72 is rebounded intermittently through the torsion energy storage ring 12, so that the material turning plate 72 in a horizontal state can be quickly rebounded when certain powder is accumulated, and the accumulated powder is driven to be suspended again and dried by the air drying mechanism 5 in the roller.
The torsion energy storage ring 12 is used by matching rotation of the roller 1 and rotation of the special-shaped gear shaft 73 in the process of rotating the driving gear groove cylinder 71, wherein the roller 1 rotates to drive the outer limiting ring 121 of the torsion energy storage ring 12 to synchronously rotate, the outer limiting ring 121 drives the inner fixing ring 122 to elastically rotate under the action of the outer fixing torsion spring 123 arranged on the inner side of the outer limiting ring 121, then the inner fixing ring 122 drives the gear groove cylinder 71 to rotate, and the material turning plate 72 is limited by the turning plate limiting lug 124 on the inner end face of the outer limiting ring 121 until the material turning plate 72 rises to a set height along the inner side of the roller 1.
When the special-shaped gear shaft 73 rotates, the belt transmission wheel 732 and the rotating shaft 731 are driven by the reducing motor 74 to rotate in the opposite direction relative to the roller 1, then the special-shaped half gear 733 is driven by the rotating shaft 731 to rotate, the tooth-shaped protrusions distributed on one half of the outer side of the special-shaped half gear 733 are meshed with the tooth grooves recessed at the tail end of the tooth groove cylinder 71 along with the rotation of the special-shaped half gear 733, and the material turning plate 72 is driven by the tooth groove cylinder 71 to move downwards along the inner side of the roller 1 until the material turning plate 72 is limited by the plate turning limiting bump 124 on the inner end face of the outer limiting ring 121 when the height of the material turning plate 72 along the inner side of the roller 1 is reduced to a horizontal state.
At this time, as the drum 1 continuously rotates, the external fixation torsion spring 123 continuously accumulates torsional potential energy, and as the rotating shaft 731 continuously rotates until the toothed convex part on the outer side of the shaped half gear 733 completely disengages from the tail end groove of the tooth-grooved drum 71, at this time, the external fixation torsion spring 123 releases the torsional potential energy to drive the tooth-grooved drum 71 to rapidly rotate, so that the material turning plate 72 fixed by the tooth-grooved drum 71 rapidly moves upwards along the inner side of the drum 1, and thus the powder accumulated on the material turning plate 72 is bounced.
