The pressing device for producing the release liner according to claim 7, wherein an adjusting bolt (72) is fixedly arranged at the bottom of the supporting plate (71), the adjusting bolt (72) penetrates through the supporting plate (71) to be connected with a telescopic spring (73), and the telescopic spring (73) is fixedly connected with the bottom of the scraping plate (74).
9. The pressing device for producing the release transfer film according to claim 8, wherein guide rollers (11) are arranged above and below the coating mechanism (4), and limiting discs (12) are arranged at two ends of each guide roller (11); an extrusion rod (13) is arranged above the scraping plate (74), and a traction roller (14) is arranged on one side of the extrusion rod (13).
10. The laminating method of the laminating device for producing the release transfer film is characterized by comprising the following steps of:
firstly, unreeling release transfer films by two unreeling rollers (2), and firstly, dedusting the upper surface and the lower surface of the two release transfer films by a dedusting mechanism (5); then respectively conveying from the upper part and the lower part of the coating mechanism (4);
step two, a release transfer film conveyed from the upper part of a coating mechanism (4) is coated, a glue feeding pipe (43) conveys glue into a glue spraying roller (42), then the glue is sprayed through a first glue spraying mechanism, and when the release transfer film with reduced thickness is sprayed, a rotary adjusting pipe (41) is rotated, and the glue is sprayed through a second glue spraying mechanism;
step three, the sprayed release transfer film is uniformly scraped through a scraping plate mechanism (7), the upper surface of the release transfer film is limited by an extrusion rod (13), a scraping plate (74) is uniformly scraped in contact with the lower surface of the release transfer film, and redundant spraying liquid flows into a V-shaped collecting plate (76) from the scraping plate (74);
step four, extruding and forming two release transfer films through two compression rollers (31), and starting a transmission gear (35) to rotate in the extruding process so as to drive a cutting knife (33) to rotate and cut off glue on two sides of the release transfer films; and finally, winding by a winding roller (6).
