Zusammenfassung: | A vacuum type device for continuously producing a microprism reflective film comprises a rack, a vacuum chamber and an edge pressing mechanism, the edge pressing mechanism is arranged in the vacuum chamber, and the edge pressing mechanism comprises a feeding roller, a receiving roller, a mold belt, a heating roller, a tensioning roller, a first pressing roller and a second pressing roller. The microprism reflective film is produced in a vacuum chamber environment, no air exists between the thermoplastic film and the mold belt, and the thermoplastic film can be tightly attached to the mold belt when being subjected to hot pressing, so that microprism stripes on the thermoplastic film are matched with stripes on the mold belt in shape, edges and corners of the microprism stripes can be made smaller, higher and more accurate, and the microprism reflective film can be manufactured more accurately. And the reflection effect is good in use. The whole hot-pressing process can be continuously carried out, and the pro |
