Abstract

The invention discloses a method for remodeling a common dry compound machine into a dry and solvent-free compound machine. The manner that a scraper of a glue spreading unit in the prior dry compound machine scrapes unwanted tackiness agents on a knurled roll from top to bottom is changed into the manner that the unwanted tackiness agents are scraped on the other side of the knurled roll from bottom to top. Two baffle plates are arranged between the scraper and the knurled roll, and the scraper, the baffle plates and the knurled roll form a new glue groove; a platen heater is arranged on theback surface of the scraper. The remodeled glue spreading unit not only can spread solvent type tackiness agents, but also can spread solvent-free tackiness agents, thereby leading the remodeled compound machine to not only execute the dry compound production, but also to realize the solvent-free compound production.

Description

Technical field [0001] The invention relates to a technical transformation scheme of a plastic film composite production equipment, in particular to a method of refitting an existing ordinary dry composite machine to a dry method and a solvent-free dual-purpose composite machine Background technique [0002] At present, the well-known plastic film composite production equipment mainly includes dry laminating machine, extrusion laminating machine, solvent-free laminating machine and so on. Among them, the dry laminating machine is similar to the solvent-free laminating machine. Both use a rubber roller to apply the adhesive to the surface of a substrate to be composited, and then laminate with another substrate to obtain a composite film after curing. . The difference is that after dry compound coating, the organic solvent in the adhesive needs to be removed in the drying tunnel and then compounded, while the solvent-free compound can be compounded directly after the glue is appl...
