The photoelectric detection switch 44 is provided at the center of the bottom of the groove 43, and the presence or absence of the plastic bottle in the groove 43 can be detected by the passage of the photoelectric detection switch 44.
The controller judges whether plastic bottles are placed on the groove 43 or not according to signals fed back by the photoelectric detection switch 44. When a plastic bottle is placed on the groove 43, the controller controls the first cylinder 420 to extend, and then controls the second cylinder 422 to extend, so that the semicircular arc clamping plate 423 clamps the body of the plastic bottle, and the pressure sensor is tightly attached to the body of the plastic bottle. At this time, the third cylinder 411 is controlled to descend, the outlet pipe 433 is hermetically connected to the opening of the plastic bottle, the valve 434 is opened, and the plastic bottle is inflated through the inlet pipe 432.
When the plastic bottle is inflated, the plastic bottle expands, the outer side wall of the plastic bottle can compress the pressure sensor, the pressure sensor detects the readings, and if the pressure detected by the pressure sensor keeps unchanged within a certain time, the sealing performance of the plastic bottle is proved to be good. If the pressure detected by the pressure sensor decreases within a certain time, it is proved that the plastic bottle is defective.
And a viscous rubber ring is fixedly mounted at the air outlet end of the air outlet pipeline 433, and the viscous rubber ring can be hermetically mounted at the opening of the plastic bottle so as to ensure that the air outlet pipeline 433 is hermetically connected with the opening of the plastic bottle.
Through the gas leakage detection device 4 of this embodiment, can detect the plastic bottle, its simple structure, with low costs and convenient to use are favorable to improving work efficiency and economic benefits. Meanwhile, the controller is used for carrying out data analysis through pressure signals fed back by the photoelectric detection switch 44 and the different pressure detection mechanisms 42, so that the yield of the plastic bottles can be calculated, and two purposes are achieved.
In this embodiment, the number of the grooves 43 and the number of the air outlet pipes 433 can be increased or decreased according to actual needs, the size of the grooves 43 also needs to be adjusted according to the size of the plastic bottle, and the height of the photoelectric detection switch 44 and the type of the pressure sensor, etc., which can be adjusted by those skilled in the art, and will not be described herein.
