Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a self-rotating circular plate thermoforming machine. Background Art

[0002] Aquaculture ponds in factory-scale closed-circulation water fish farming are an advanced fish farming technology designed to improve farming efficiency and sustainability through highly controlled environmental conditions. In this system, aquaculture ponds are one of the core components and are used as space for fish growth. Aquaculture ponds can be round, square or other shapes, and are usually made of corrosion-resistant, non-toxic materials such as plastic, fiberglass, etc. to ensure water quality safety and long-term use of the system.

[0003] There are two main methods for the production and installation of aquaculture ponds on the market. The first is manual on-site welding, which has the disadvantages of long welding hours, high costs, and high welding skills requirements for welders; the second is equipment welding, integrated overall molding, which has low transportation efficiency and high installation costs. It requires large vehicles to transport to the breeding plant area. When installing fish ponds on the breeding site, large mechanical equipment (crane) is now required for installation. The integrated molding method may encounter various problems during transportation, such as tooling during transportation and height restrictions. Relatively speaking, on-site welding is still the best choice for the production and installation of aquaculture ponds.

[0004] On-site welding of circular aquaculture ponds requires welding the bottom plate and the side plate. Before welding, the bottom plate needs to be bent to form an edge to increase the welding connection area. How to bend the circular bottom plate through equipment is a problem we face.
