[0022] In order to better achieve the purpose of the present invention, the present invention also provides a method for using an intelligently controlled plastic article sealing performance detection device, comprising the following steps:

[0023] Step 1: When performing a sealing test on a plastic article with ordinary sealing requirements, the system controls port 1 of electromagnetic three-way valve 1 to be connected with port 3, controls port 1 of electromagnetic three-way valve 3 to be connected with port 3, controls port 2 of electromagnetic three-way valve 4 to be connected with port 3, and controls port 1 of electromagnetic three-way valve 2 to be connected with port 2. At this time, electromagnetic three-way valve 4 is closed, and the air pump is started. Air flows in from port 2 of electromagnetic three-way valve 2 and passes through port 1 of electromagnetic three-way valve 2, air pump, port 1 of electromagnetic three-way valve 1, port 3 of electromagnetic three-way valve 1, three-way pipe 1, air inlet end 1 of two-inlet and two-outlet pneumatic slip ring, air outlet end 1 of two-inlet and two-outlet pneumatic slip ring, port 1 of electromagnetic three-way valve 3, port 3 of electromagnetic three-way valve 3, and finally flows into the air inlet to pressurize the interior of the plastic article. When the pressure reaches a preset value, electromagnetic three-way valve 3 is closed.

[0024] Step 2: When the gas in the plastic article in step 1 is discharged, the system controls the second port of the electromagnetic three-way valve 4 to be connected to its third port, and the high-pressure gas in the plastic article is discharged through the exhaust port, the third port of the electromagnetic three-way valve 4, and the second port of the electromagnetic three-way valve 4 in sequence;

[0025] Step 3: When performing a sealing performance test on a special plastic article, the system controls port 2 of electromagnetic three-way valve 3 to connect with port 3, closes electromagnetic three-way valve 4, and allows helium in the helium cylinder to flow into the plastic article through port 2 of electromagnetic three-way valve 3, port 3 of electromagnetic three-way valve 3, and the air inlet in sequence. Subsequently, port 1 of electromagnetic three-way valve 3 is controlled to connect with port 3, and step 1 is repeated.

[0026] Step four, when the gas in the plastic article in step three is discharged, the system controls the port one of the electromagnetic three-way valve two to communicate with its port three, controls the port one of the electromagnetic three-way valve one to communicate with its port two, controls the port one of the electromagnetic three-way valve four to communicate with its port three, starts the gas pump, and the mixed gas in the plastic article sequentially passes through the exhaust port, the port three of the electromagnetic three-way valve four, the port one of the electromagnetic three-way valve four, the gas inlet end two of the two-in and two-out pneumatic slip ring, the gas outlet end two of the two-in and two-out pneumatic slip ring, the three-way pipe two, the port three of the electromagnetic three-way valve two, the port one of the electromagnetic three-way valve two, the gas pump, the port one of the electromagnetic three-way valve one, and finally the port two of the electromagnetic three-way valve one to be discharged into the helium recovery device.

[0027] Step five, when the plastic articles of different heights are adapted, the double slide table linear module is started, the double slide table linear module drives the double-station tool assembly, the blocking and distributing assembly, and the detection assembly to be synchronously adjusted in height as a whole;

[0028] Step six, when the plastic articles of different maximum radii are adapted, the bidirectional linear module is started, and the two output slides of the bidirectional linear module move in opposite directions to adjust the spacing of the cover;

[0029] Step seven, the output slide of the bidirectional linear module on the right side drives the connecting rod to move, the connecting rod drives the middle connecting column to move, since the left connecting column of the two-stage scissor mechanism is fixed with the mounting plate one, the two-stage scissor mechanism as a whole is scissored, the right end connecting column of the two-stage scissor mechanism drives the mounting slide to slide in the limiting sliding groove, and the mounting slide drives the air cylinder two to adjust the position;

[0030] Step eight, when the plastic articles are sealed, the output end of the air cylinder two is extended to block the rightmost plastic article, the air cylinder one drives the spline shaft to descend, the spline shaft drives the cover to descend, and the outer wall of the conical sealing rubber bowl in the cover is in contact with the mouth of the plastic article to seal;

[0031] Step nine, when the plastic article is of ordinary sealing requirement, after steps one and two are performed, whether the air pressure of the plastic article changes is detected by the air pressure sensor;

[0032] Step ten, when the plastic article is of special sealing requirement, steps eight, three, and four are performed, the right motor is started again, the output end of the motor drives the belt pulley assembly to rotate, the belt pulley assembly drives the spline sleeve to rotate, the spline sleeve drives the spline shaft to rotate, the spline shaft drives the cover to rotate, the cover drives the conical sealing rubber bowl to rotate, the conical sealing rubber bowl drives the right plastic article to rotate on the belt conveying line, the fan is started to increase the air flow rate, and the helium is detected by the helium detector;

[0033] Step eleven, when the detection is completed, the air cylinder one is started to reset so that the conical sealing rubber bowl is separated from the mouth of the plastic article, the output end of the air cylinder two is retracted, and the belt conveying line is started again to transport the next two plastic articles to the corresponding positions.

[0034] The beneficial effects of the present application compared with the prior art are: 1. The plastic articles are conveyed by the belt conveying line, the height of the double-station tool assembly and the blocking and distributing assembly is synchronously adjusted by the double-sliding-table linear module to adapt to the detection needs of plastic articles of different heights, the distance between the two rotary downward pressing assemblies is adjusted by the bidirectional linear module to adapt to plastic articles of different maximum radii, the plastic articles are pressed and sealed downward and driven to rotate by the rotary downward pressing assembly driving the sealing assembly, and the plastic articles that do not meet the sealing detection requirements are removed by the blocking and distributing assembly.

[0035] 2. When adapting to plastic articles of different maximum radii, the output end of the air cylinder 2 needs to be adjusted by a distance twice the distance of the right end cover, and the movement distance of the right end connecting column of the two-stage scissor mechanism is twice the distance of the middle connecting column, thereby achieving synchronous adjustment of the air cylinder 2 and the right end cover position.

[0036] 3. The system control air path control assembly and the double-station tool assembly are intelligently switched to execute two detection modes for plastic articles with ordinary sealing requirements and characteristic sealing requirements. BRIEF DESCRIPTION OF DRAWINGS
