Example Embodiment
[0011] The existing technology is to perforate the surface of the PE film coated with medical adhesive by heating the burr roller to achieve the purpose of tearing.
[0012] The method of the present invention changes the heating circulation path of the heat transfer oil in the roller of the burr roller, eliminates the inner wall of the roller in the internal structure of the burr roller, the heat transfer oil flows directly in the roller, and expands the inlet and outlet diameter of the heat transfer oil circulation path to 227mm , Enlarge the heat-conducting oil passage, fill the roller with heat-conducting oil, the heat-conducting oil flows smoothly, and speeds up the circulation of the heat-conducting oil. Therefore, the inner wall of the burr roller will not be carbonized, preventing the heat-conducting oil from clogging, and even heating the burr roller. After the burr roll is heated by the heating circulation system of the present invention, the medical PE film is rolled, a...
