Wrinkling preventing device of laminator

The utility model discloses a wrinkling preventing device of a laminator. The wrinkling preventing device comprises a pressing roller, a laminating platform, a heating furnace and a fan, wherein two ends of the pressing roller are provided with connecting shafts; the connecting shafts are connected with an air outlet of the heating furnace through guide pipes; an air inlet of the heating furnace is connected with the fan through a guide pipe; the connecting shafts are also sleeved by bearings; the bearings are connected with a separator through connecting rods; and baffles are arranged around the laminating platform and concretely comprise a front baffle, a rear baffle, a left baffle and a right baffle, wherein a discharging hole is formed in the front baffle, a first feeding hole and a second feeding hole are formed in the rear baffle, and a fine guide roller is arranged between the first feeding hole and the second feeding hole. According to the wrinkling preventing device, paper and a film are separated firstly through the fine guide roller, a Teflon layer is coated on the surface of the fine guide roller to ensure that the fine guide roller is smooth and incapable of wrinkling, then, the separator is used for carrying out finishing work before laminating to ensure that the surfaces of the film and the paper are level enough, and next, softening treatment is carried out by virtue of hot air, so that no air exists between the paper and the pressing roller and no air bubbles or wrinkles are generated in the laminating process.
