Description

Technical Field

[0001] The utility model relates to the technical field of folding cover opening, in particular to a cleaning tank with an automatic folding cover opening mechanism. Background Art

[0002] Impregnation technology is a microporous sealing process that seals the gaps by infiltrating a sealing medium into the micropores through natural infiltration, vacuuming, or pressurization. The sealing medium in the gaps is solidified by cooling or heating. A post-impregnation cleaning tank cleans the workpiece surface, cavity, and threaded holes after impregnation and drying, removing any residual impregnation liquid. During the spray cleaning process, the water flow is highly impactful, so a retractable lid is required on the top of the cleaning tank to prevent spillage and contamination of the factory floor and environment.

[0003] The lid of the cleaning tank is usually opened and closed manually. As the size of the cleaning tank becomes larger and larger, manual opening and closing requires more and more physical strength, and there are also certain safety risks. Therefore, some automatic opening and closing lid devices for cleaning tanks have appeared in the prior art, such as:
