Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of coating spraying, and in particular, to a cast iron pot coating spraying device with a coating homogenization function. Background Art

[0002] Cast iron pans are commonly used kitchen utensils in real life. In the production process of cast iron pans, the casting, polishing and coating spraying operations of the cast iron pans need to be completed in sequence.

[0003] In the prior art, most methods for spraying cast iron pots are to use spraying equipment to spray the surface of the cast iron pot. People will use centralized spraying equipment to perform the main spraying operation on the surface of the cast iron pot. However, after the cast iron pot is fixed, it will move with the spraying production line. During the movement of the cast iron pot, the coating is discharged in a spraying manner during the spraying of the cast iron pot by the spraying equipment. Therefore, when spraying the cast iron pot, it is difficult to ensure that the cast iron pot is fully sprayed in all directions. Therefore, after the spraying operation of the cast iron pot is completed using the spraying production line, it is often necessary to manually fill the gaps between the cast iron pot coatings and manually spray.

The circulating transmission belt 10 drives the connecting rod 11 and the sliding sleeve 2 to slide on the annular movable slide rail 12, and during the movement of the sliding sleeve 2, the sliding member 18 connected to the lifting rod 3 also slides on the annular curved slide rail 5. After the sliding member 18 moves to the lifting section 7, the mounting plate 4 and the cast iron pot are also moved into the spraying chamber 8, and then the sliding member 18 drives the lifting rod 3 and the mounting plate 4 to rise in the spraying chamber 8. In the process of the cast iron pot rising, rotating and moving at the same time, multiple spraying devices 28 at different heights are used to spray paint on the inside of the cast iron pot, and the paint after spraying is sufficiently homogenized.
