Embodiment 1

[0057] Such as figure 1 As shown, the embodiment of the present invention discloses a tank coating integrity tester, including a host display controller 100, a tank body support 200 electrically connected to the host display controller 100, such as figure 2 As shown, the host display controller 100 includes a communication connector 101, a host box 102, a display screen 103, a charging connector 104, a foot switch line 105, a fixture connection line 106, a power supply 107, and a keypad 108. The fixture connection line 106 is connected with the fixture connection line 201 on the can body support 200 to realize the electrical connection between the host display controller 100 and the corresponding structure on the can body support 200 .

[0058] The tank body support 200 in this embodiment is specially applied to the sample tank 300 of the two-piece tank type.

[0059] Such as Figure 3-5 As shown, the can body support 200 in this embodiment includes a bottom plate 202, and ...

Embodiment 2

[0070] The tank body support 200 in this embodiment is specially applied to the sample tank 300 of the three-piece tank type.

[0071] The structure of the can body bracket 200 in this embodiment is basically the same as that applicable to two-piece cans in Embodiment 1, the difference is that, as Figure 6-7 As shown, the bottom scraping needles 203 in this embodiment are arranged in three characters, and the bottom scraping needles 203 are electrically connected to the host display controller 100 through the fixture connection line 201 to detect whether the sample tank is in contact with the bottom scraping needles 203 Scrape through the outer coating. Two auxiliary support strips 213 are added to the sides of the bottom scraping needle 203, and the height of the auxiliary support strips 213 is lower than that of the bottom scraping needle 203 (preferably 1mm lower), which can properly support the sample tank and reduce the tilting of the sample tank.

[0072]In this embodi...

Embodiment 3

[0075] The tank body support 200 in this embodiment is specially applied to the spray sample tank 300 .

[0076] The structure of the can body support 200 in this embodiment is basically the same as that applicable to two-piece cans in Embodiment 1, the difference is that the electrode needles in this embodiment are further designed as a telescopic structure, that is, the telescopic length can be quickly Adjustment, the electrode needle can also be pulled out for replacement, so as to adapt to the height of different sample tanks in a wider range. Additionally, if Figure 8 As shown, the bottom scraping needles 203 in this embodiment are arranged in three characters, and the bottom scraping needles 203 are electrically connected to the host display controller 100 through the fixture connection line 201 to detect whether the sample tank is in contact with the bottom scraping needles 203 Scrape through the outer coating. Two auxiliary support strips 213 are added to the sides ...

Abstract

The invention discloses an in-can coating film integrity tester, which comprises a host display controller and a can body support electrically connected with the host display controller, wherein the can body support comprises a bottom plate, bottom scraping needles are arranged at the positions, close to the middle, of the upper surface of the bottom plate, and the bottom scraping needles are arranged in a triangular shape and electrically connected with the host display controller; a supporting stand column is arranged at the position, close to the edge line of the bottom plate, of the uppersurface of the bottom plate, the supporting stand column is composed of an outer stand column and an inner stand column, and the outer stand column can ascend and descend along the inner stand columnand can ascend, rotate forwards, rotate reversely and descend. A fixing arm is movably connected to the outer stand column, and a testing probe and a water level probe are installed on the bottom faceof the end, away from the outer stand column, of the fixing arm. The tester is easy to operate, measurement is more sensitive, more reliable and more accurate, and the defects in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of bottle and can inspection, and more specifically relates to an instrument for measuring the integrity of coating film in a can. Background technique [0002] When the can factory produces cans, it is necessary to check the integrity of the coating film in the tank. If the coating film in the tank is incomplete, if it is not dense or damaged, the contents will corrode the metal of the tank body, which will affect the quality and storage of the product. In order to ensure the quality and safety of metal packaging cans during the delivery period, it is necessary to inspect the inner wall of the metal cans to eliminate products with potential corrosion safety hazards. [0003] When measuring the thickness and uniformity of the coating film in the tank, firstly, manual operation can be used to measure by injecting the electrolyte into the tank and holding the electrode. The anode extends into the electrolyte a...
