Description

Technical Field

[0001] The utility model relates to the technical field of hot presses, in particular to a hot press for producing solar glass panels. Background Art

[0002] Solar energy is a sustainable and environmentally friendly energy source that is gaining more and more attention. Special solar glass panels are needed in photovoltaic modules. When producing solar glass panels, the photovoltaic embossed glass formed by the photovoltaic calender is annealed and cooled in the annealing kiln, and finally sent to the photovoltaic cell module manufacturer for subsequent surface treatment. It is necessary to use a hot press to process the glass, resin material and other fiber materials under high temperature and high pressure to form a strong and durable composite material.

[0003] When the existing hot press is in operation, the bottom mold device will move toward the upper mold device, so that the bottom mold device is tightly fitted to the upper mold device. At the same time, the bottom mold device will generate a pressing force on the upper mold device. At the same time, because the bearing seat is pivoted on the pivot hole through the pivot part, the pressing force will cause a certain stress to the pivot part. Therefore, it is generally manufactured to avoid the pivot part from being able to withstand a large stress. When selecting the pivot part, a higher strength specification must be used, so the required manufacturing cost will be relatively increased.

[0004] To this end, we propose a hot press for producing solar glass panels. Utility Model Content
