辊式泡罩包装机工作原理:成型膜经加热装置加热软化，在辊筒式成型模辊上用真空负压吸出泡罩，充填装置将被包装物充填入泡罩内，然后经辊筒式热封合装置，在合适的温度及压力下将单面涂有粘合剂的覆盖膜封合在带泡罩材料表面，并将被包装物密封在泡罩内。再经打字、压印装置打印上批号及压出折断线，最后冲切装置冲切成一定尺寸的产品板块。
Working principle of roller blister packaging machine: the forming film is heated and softened by heating device, and the blister is sucked out by vacuum negative pressure on the roller forming mould roller. The packing material is filled into the blister by the filling device, and then the covering film coated with adhesive on one side is sealed on the surface of the material with blister under appropriate temperature and pressure by the roller type thermal sealing device, and the packaged material is sealed in the blister 。 After that, the batch number is printed and the fracture line is pressed out by the printing and pressing device. Finally, the punching and cutting device is used to cut the product plate with a certain size.
