A foaming apparatus for a paper container, including:
- a main body, the main body being divided into a feeding and pick-up area, a preheating area, a heating area and a cooling area on a horizontal plane, wherein the preheating area, the heating area and the cooling area each include a guiding portion arranged thereinside;
- a delivery mechanism, the delivery mechanism including a chain in closed circulation, the chain extending back and forth on the horizontal plane, extending along the feeding and pick-up area, the preheating area, the heating area and cooling area in sequence, and extending back to the feeding and pick-up area, the chain extending zigzag within the preheating area, the heating area and the cooling area, respectively, so that the chain extends back and forth within respective one of the preheating area, the heating area and the cooling area;
- a plurality of supports, each of the plurality of supports including a supporting portion and a base, the bases of the plurality of supports being connected to a side of the chain in intervals, the supporting portion being rotatably disposed on the base and configured to support the paper container, wherein when each of the plurality of supports moves with the chain within the preheating area, the heating area and the cooling area, the guiding portion and the supporting portion frictionally contact with each other so that the supporting portion rotates;
- a heating mechanism, arranged within the preheating area and the heating area to heat the preheating area and the heating area, the temperature in the preheating area being lower than the temperature in the heating area;
- a cooling mechanism, arranged within the cooling area to cool the cooling area;
- and
- a feeding mechanism and a pick-up mechanism, arranged correspondingly above the feeding and pick-up area, the feeding mechanism being adjacent to the preheating area, the pick-up mechanism being adjacent to the cooling area, the feeding mechanism placing the paper container on the supporting portion of each of the plurality of supports, the pick-up mechanism picking up the paper container from the supporting portion of each of the plurality of supports;
- wherein a first partition is arranged between the preheating area and the heating area, and a second partition is arranged between the heating area and the cooling area;
- wherein the heating area includes a main heating area and a temperature-lowering area, the main heating area is adjacent to the preheating area, the temperature-lowering area is adjacent to the cooling area, the temperature in the temperature-lowering area is lower than the temperature in the main heating area, and a third partition is arranged between the main heating area and the temperature-lowering area;
- wherein the main body includes a base body and a cover, and the cover is rotatably connected to the base body;
- the chain, the plurality of supports, the first partition, the second partition and the third partition are disposed on the base body;
- a first plate, a second plate and a third plate are disposed on a side of the cover facing toward the base body;
- the first plate, second plate and third plate correspond to the first partition, second partition and third partition, respectively;
- the main body includes a front side and a rear side, the front side and the rear side define a longitudinal direction;
- the first plate, the second plate, the third plate, the first partition, the second partition and the third partition extend in the longitudinal direction;
- when the cover covers the base body, the first plate and the first partition are abutted against each other, the second plate and the second partition are abutted against each other, and the third plate and the third partition are abutted against each other.
