Description

Technical Field

[0001] The utility model relates to the technical field of pressing machines, and more particularly to a pressing machine for laminated glass. Background Art

[0002] During the production of laminated glass, a film is typically placed between two or more pieces of glass. A press then preheats and pre-presses the glass and film. After this process, the glass is placed in an autoclave for high-temperature, high-pressure compaction, completing the laminated glass production. Existing presses often have problems adjusting the distance between the two rollers used to press the glass, or even aligning them after adjustment. This makes it difficult for the two rollers to operate synchronously to press the glass. Furthermore, existing presses have a hot air outlet that blows out hot air to heat the glass, but this air is difficult to recycle, resulting in heat loss and low energy efficiency.
