Description

Technical Field

[0001] The present invention relates to the field of composite technology, and particularly to a five-in-one thermal laminating machine for continuous double hot pressing and lamination. Background Art

[0002] Polytetrafluoroethylene microporous membranes have unique nodular fibrillarity, smooth surfaces, chemical resistance, air permeability without water permeability, large air permeability, flame retardancy, high temperature resistance, strong acid and alkali resistance, non-toxicity, etc. By means of a hot pressing process, polytetrafluoroethylene microporous membranes are laminated on various fabrics and substrates to become new type of filter materials, which have been widely used in air dust removal and air purification. Commonly used filter materials on the market are two-in-one products of substrates and polytetrafluoroethylene microporous membranes, three-in-one products of substrates, polytetrafluoroethylene microporous membranes and substrates, and there are also some five-in-one products of substrates, polytetrafluoroethylene microporous membranes, substrates, polytetrafluoroethylene microporous membranes and substrates with higher filtration precision. At present, the production process of two-in-one and three-in-one filter materials is three-layer unwinding, two groups of hot rollers for counter-pressure, edge trimming, inspection and winding. For the production of five-in-one filter materials, it is compounded in two steps. First, it is a three-in-one compounding, and then the three-in-one product is compounded with the other two layers. For the production of the three-in-one semi-finished products of five-in-one filter materials, there are phenomena of heating, cooling and reheating, which not only wastes energy, but also the three-in-one semi-finished products are relatively thick and the secondary heating time is long. At the same time, there are also processes such as two inspections and two windings, which seriously affect the production speed. How to save energy and improve production efficiency is a difficult problem that technicians urgently need to solve at present. Summary of the Invention
