Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing of reflective films, in particular to a hot pressing device for producing reflective films. Background Art

[0002] Traditional reflective film generally needs to be stretched during production to make it as thin as paper, and then hot pressed to shape it. Hot pressing can make the film tougher, which is convenient for later lamination. With the development of modern technology, reflective film is used more frequently. The most important processing flow for reflective film is hot pressing to improve its overall stretchability and toughness. Hot pressing can make the reflective material on the top fit better with the film itself, and increase the quality of the reflective film.

[0003] Patent authorization announcement number CN211105541U provides a hot pressing device for producing reflective film, and the hot pressing layer provides a power line connected to the switch group. The utility model has a fixed column, protective rubber and exhaust pipe, and the structure is simple, which is conducive to the stable expansion and contraction of the upper and lower hot pressing plates, and is conducive to preventing internal bubbles from appearing during hot pressing of reflective film, which is convenient for market promotion and application.

[0004] However, the above technical solution has the following shortcomings: on the one hand, the hot pressing plate needs to work continuously to heat press the reflective film section by section, and the upper and lower hot pressing plates need to be separated when rolling up the reflective film, and the upper and lower hot pressing plates need to be closed when heating the reflective film, resulting in low production efficiency of the reflective film. On the other hand, when the hot pressing plate heat presses the reflective film section by section, a hot pressing interface is likely to appear between the two hot pressing sections, affecting the overall quality of the reflective film.
