Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] The preferred embodiment of the present invention is shown in FIG. 1 , which includes a host 1 , a test head 2 and a test water tank 3 . The host machine 1 is provided with a pressure control device 11 inside, and the pressure control device 11 is connected to the test head 2 through a gas pipeline 12 . A controllable solenoid valve 15 is arranged between the pressure sensor 11 and the gas pipeline 12 to control the communication / closing between the pressure sensor 11 and the gas pipeline 12, and the entire experimental process is controlled by a PLC liquid crystal display programmable controller 16 and display.

[0016] When carrying out the sealing test, as shown in Figure 1, fill the test water tank 3 with water, open a small hole with a diameter of 2-3mm on the top of the container 4, and insert the test head 2 into the preform 4 through the small hole, and...

Abstract

The invention provides a sealing detection instrument for a bottle, a bottle cover and a sealed tank container and comprises a host, a testing head and a testing water tank. The host is provided with a pressure control device and the pressure control device is connected with one end of a gas path pipeline through a controllable electro-magnetic valve; the other end of the gas road pipeline is connected with the testing head; the gas path pipeline, the testing head as well as the pressure control device are sealed in an air-tight way; the host is also provided with an adjusting valve which can adjust the gas pressure outputted by the pressure control device; the host is also provided with a pressure sensor to sense the pressure in the tested container; a PLC liquid crystal display programmable controller can control and display the tested data. When in test, a small hole is drilled on the cover of the tested bottle base and the testing head is inserted into the hole while the hole is sealed in an air-tight way; the pressure control device outputs pressure and the pressure sensor tests the pressure in the bottle; a PLC display screen displays the tested data; the tested container is put into the testing water tank under the water level for observation of the phenomenon of leakage and pressurization. Therefore, the sealing and the firmness of the connection between the bottle body and the bottle cover as well as the anti-pressure level of the bottle body can be tested. The invention can be applied in the field of the leak tightness test of the bottle, the bottle cover and the sealed container.

Description

technical field [0001] The invention relates to a sealing tester for bottles, bottle caps and sealed jars. Background technique [0002] Bottles and airtight containers are very common items in everyday life. Generally, the sealing requirements of the container are not high, and it only needs to be airtight so that the liquid contained in it will not flow out. However, many airtight containers need to achieve a certain pressure resistance and airtightness to make the liquid contained inside safe during canning, transportation, and storage, such as carbonated beverages. In the prior art, there is no good detection method for the detection of the airtightness of bottles, bottle caps and sealed jars. Contents of the invention [0003] Aiming at the defects and deficiencies in the prior art, the object of the present invention is to provide a bottle, bottle cap and airtight can seal tester, which can detect the airtightness and pressure resistance of the bottle, bottle cap a...
