Description

Positive pressure air supply inspection equipment for sealing performance of bottle mouth of glass bottle Technical Field The invention relates to inspection equipment, in particular to positive pressure air supply inspection equipment for sealing performance of a glass bottle opening, and belongs to the technical field of glass bottle processing. Background The prior intermittent air-tightness detection mechanism generally detects a bottle by making up and down reciprocating movement of a connected hollow shaft consisting of an air-tight head and a hollow shaft, and when the connected hollow shaft descends to the end face of the air-tight head to be pressed on the end face of the bottle mouth of the bottle, the connected hollow shaft and the inner cavity of the bottle form a closed space. At this time, the intermittent inflating pump at one end of the connected hollow shaft is added with positive pressure, at this time, the closed space generates air pressure, and the air pressure is read out by the air pressure sensor and transmitted to the computer system. The data range is set in the computer, the value read by the air pressure sensor is compared by the computer, if the value is in the data range set by the computer, the detected bottle opening tightness is qualified, and the non-detected bottle opening tightness is unqualified. Because the working principle of the intermittent air pump is that the connected hollow shaft is sealed into the air tank by a piece of rubber sheet, the volume of the air tank is reduced by pushing the rubber sheet upwards by the electromagnetic valve so as to increase the air pressure in the connected hollow shaft. It can be seen that the intermittent inflation pump produces very little air pressure. In the practical application process. The air pressure generated by the intermittent inflating pump is very small. Especially for the detection of big bottle, the numerical error of the atmospheric pressure sensor reading is very big, even does not read the numerical value, so often causes the condition of missing to examine and beat by mistake.
