Description

Technical Field

[0001] This invention relates to an automated steel drum cleaning device, belonging to the field of packaging equipment technology. Background Technology

[0002] Steel drums are a traditional container, holding a very important place among traditional containers. Evolving from their function of temporarily storing contents, steel drums are now widely used in industrial packaging, sales packaging, and transport packaging. From production to distribution and consumption, they have become a flowing container, serving as a means of long-term preservation of contents. It can be said that steel drums have brought significant changes and progress to human work and life. Because the contents of steel drums are in direct contact with the inner surface, the inner surface of the drum needs to meet specific chemical and physical performance requirements to accommodate the various characteristics of different contents. Many industries' products (such as high-grade lubricants and high-gloss paints) have extremely high requirements for the cleanliness of the inner surface of the container. Steel drums produced using existing phosphating cleaning processes can no longer meet customers' further requirements for cleanliness. Therefore, domestic drum manufacturers need to perform manual or semi-automated mechanical cleaning on some finished steel drums with high cleanliness requirements. However, such cleaning processes currently involve pouring special cleaning solutions into the steel drums and relying on manual scrubbing. Manual cleaning of steel drums is physically demanding and inefficient, presenting certain drawbacks. Therefore, there is an urgent need in this technical field for an automated steel drum cleaning device. Summary of the Invention
