[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers. After the bottle body is injection - blow - molded, if there are defects such as leakage holes in the bottle body, it will seriously affect the sealing performance of the bottle body.

[0003] Currently, a sealing performance detection device for blow - molded bottle production disclosed in a Chinese patent with the publication number CN211452744U includes a water tank. A fixed square plate is installed on the right side inside the water tank. A rotating turntable is installed on the left side of the fixed square plate. A protective shell is installed on the right side of the fixed square plate. A cylinder is placed inside the protective shell. The output end on the left side of the cylinder is connected to an air inlet long tube, and the other end of the air inlet long tube extends into the rotating turntable. A connection switch wire is installed on the right side of the water tank. By providing an air outlet pipe, the sealing performance of the blow - molded bottle is detected through the mutual cooperation between the air outlet pipe and the water tank.
