The bubble film machine (air cushion film machine) must assign a special operation to the equipment.

The bubble film machine (air cushion film machine) should assign a special operation to the equipment, and do not allow the extruder screw to idle without any material, so as to avoid the screw and the barrel being scratched. After the shutdown, if there is stock in the barrel, before starting the machine again, the temperature of each temperature zone must be raised to the specified requirements according to the process requirements, and the temperature can be turned on for 30 minutes to be turned on. So as not to damage the machine.
In the conceptual design process of such a large complex machine of the bubble film machine (air cushion film machine) group, a large amount of conceptual information is awaiting processing. In order to clearly and clearly express the structural relationship and mutual mapping of conceptual information at various levels, it is necessary to study the model problem of conceptual design.
