辊式泡罩包装机的工作原理：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。
The working principle of roller type blister packaging machine: the forming film is heated and softened by the heating device, the blister is sucked out by the vacuum negative pressure on the roller type molding die roll, the filling device fills the package into the blister, and then, through the roller type heat sealing device, the covering film with adhesive on one side is sealed on the surface of the material with blister under the appropriate temperature and pressure, and the package is sealed on the blister Inside the hood. After that, the batch number and break line are printed on the printing and stamping device, and finally the punching and cutting device is used to cut the product plate of a certain size.
