[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a cooling device for producing food-grade plastic cups, including a conveyor belt 1, a box body 2, a mesh grille 3 and a cooling box 4. The box body 2 is fixedly installed on the top of the conveyor belt 1, the mesh grille 3 is provided on the right side of the top of the box body 2, and the cooling box 4 is provided on the left side of the top of the box body 2. A cooling mechanism is provided inside the cooling box 4. The blow-molded plastic cups are transported to the inside of the box body 2 by a robot, and cold air is blown toward the plastic cups through the cooling mechanism. After heat exchange with the plastic cups, the cold air can reduce the temperature of the plastic cups and flow out of the inside of the box body 2 through the leakage holes on the mesh grille 3. After the plastic cups cool down, they will fall onto the conveyor belt 1, and the conveyor belt 1 can drive the plastic cups to move outward for discharge.

[0020] A circulation mechanism is provided on the outside of the cooling box 4, and the circulation mechanism includes a water pump 9, a water inlet pipe 10 and a return pipe 11. A water pump 9 is fixedly installed on one side of the cooling box 4, and the input end of the water pump 9 is connected to the water inlet pipe 10. The bottom end of the water inlet pipe 10 is connected to the external cold water pool. The water pump 9 and the water inlet pipe 10 cooperate to transport cold water to the copper tube 8 inside the cooling box 4.

[0021] The cooling mechanism includes a fan 5, a fixing frame 6, a copper plate 7 and a copper tube 8. A fan 5 is symmetrically provided on one side of the cooling box 4. A fixing frame 6 is symmetrically fixedly connected to the inside of the cooling box 4. A plurality of copper plates 7 are installed inside the fixing frame 6. A plurality of copper tubes 8 are fixedly connected to the inside of the copper plate 7. A filter is provided on one side of the fan 5. The copper tube 8 can drive cold water to flow inside the cooling box 4, and the U-shaped structure of the copper tube 8 can extend the time for cold water to flow inside the cooling box 4. When the fan 5 draws outside air into the cooling box 4, the air will pass through the copper tube 8, wherein the copper plate 7 can increase the contact area between the copper tube 8 and the air, so that the air can fully exchange heat with the copper tube 8 containing cold water, thereby enhancing the air cooling effect. The cold air is blown towards the plastic cup to cool it down, wherein the filter can intercept the air to purify the air.

[0022] A return pipe 11 is provided on the other side of the cooling box 4. One end of the copper pipe 8 is connected to the output end of the water pump 9, and the other end of the copper pipe 8 is connected to the return pipe 11. The cold water then flows into the interior of the return pipe 11, and the return pipe 11 is connected to the cold water pool through a hose, so that the cold water flows back to the interior of the cold water pool.

[0023] A rotating frame 12 is symmetrically provided on both sides of the interior of the box body 2. A plurality of rollers 17 are equidistantly connected to the interior of the rotating frame 12. A rotating mechanism is symmetrically provided on the outside of the box body 2. The rotating mechanism includes a connecting rod 13, a cylinder 14 and a hinge seat 15. One side of the rotating frame 12 is hinged to one side of the box body 2 through a pin, and one end of the pin passes through the interior of the box body 2 and is fixedly connected to the connecting rod 13. The cylinder 14 is symmetrically hinged on both sides of the box body 2. The output end of the cylinder 14 is hinged to one end of the connecting rod 13 through the hinge seat 15. After the plastic cup enters the interior of the box body 2, it falls to the rotating frame 12. The plastic cups are supported by the rollers 17 inside the turret 12. After the plastic cups are cooled, the output end of the cylinder 14 can drive the connecting rod 13 through the hinge seat 15. The connecting rod 13 is connected to the turret 12 as a whole through a pin shaft, so as to drive the turret 12 to rotate around the pin shaft point. The output ends of the two cylinders 14 move in opposite directions, so that the two turrets 12 can rotate in different directions at the same time. When the turrets 12 rotate upward at the same time, they support the plastic cups. When the turrets 12 rotate downward at the same time, the plastic cups can roll down to the top of the conveyor belt 1 through the rollers 17, and the plastic cups are transported outward through the conveyor belt 1.

[0024] An air distribution plate 16 is fixedly connected to the left side of the top of the conveyor belt 1. A plurality of ventilation holes are equidistantly arranged inside the air distribution plate 16. The positions of the air distribution plate 16 and the mesh grille 3 are parallel to each other. An end cover is provided on the top of the box body 2. After the plastic cup falls on the rotating rack 12, the end cover can be closed on the top of the box body 2 to seal the top of the box body 2 and prevent the plastic cup from being blown off from the top of the box body 2. The air distribution plate 16 can divide the cold air into multiple streams through multiple through holes and evenly distribute them on the top of the box body 2 to cool multiple plastic cups at the same time.

[0025] The cooling device can drive cold water to flow inside the cooling box 4 through the copper tube 8, and the U-shaped structure of the copper tube 8 prolongs the time for the cold water to flow inside the cooling box 4. When the fan 5 draws outside air into the cooling box 4, the air will pass through the copper tube 8, and the copper plate 7 can increase the contact area between the copper tube 8 and the air, so that the air can fully exchange heat with the copper tube 8 containing cold water, thereby enhancing the air cooling effect. The cold air is blown towards the plastic cup to cool it down, and the filter can intercept the air to purify the air.
