[0021] In the embodiment of the utility model, the annular conveying channel includes a connecting ring 12 and a plurality of anti-slip rods 13 evenly distributed along the inner circumference of the connecting ring, and the anti-slip rods all extend along the conveying direction of the can cover.

[0022] In the embodiment of the utility model, the outer circumference of the anti-drop rod supported at the bottom of the tank cover is sleeved with a plastic sliding sleeve 14 to facilitate the sliding of the tank cover.

[0023] In the embodiment of the utility model, one end of the heat dissipation duct is connected to the drying furnace and a heat dissipation fan 15 is provided in the drying furnace to blow the air in the drying furnace out of the heat dissipation duct.
