Abstract
The utility mode relates to the field of manufacturing equipment of blow-molded plastic bottle bodies, and in particular relates to a leak hunting mechanism after blow molding of a blow molding machine. The leak hunting mechanism comprises an air source and at least two executing modules, wherein each executing module comprises an air delivery pipe, an air outlet and a pressure sensor; and the air source is hermetically connected with the air outlet by the air delivery pipe. The leak hunting mechanism is characterized by further comprising a PLC (Programmable Logic Controller) control module, an air outlet retainer, an expansion link and a sealing choke plug; both the expansion link and the sealing choke plug are matched with the executing modules in use; the fixed end of the expansion link is longitudinally fixed on the air outlet retainer, and the movable end of the expansion link can move longitudinally; the air outlet is formed in the movable end of the expansion link; the sealing choke plug penetrates through the air outlet; the pressure sensor is arranged at the end part of the air outlet; and the PLC control module is connected with the air source and the pressure sensor. By the manner, the leak hunting mechanism disclosed by the utility model is provided with a plurality of air outlets to simultaneously perform leak hunting tests on a plurality of blow-molded products, and simultaneously the efficiency of the leak hunting tests is improved by adopting the PLC to control the air outlets.
Description
Technical field
