Description

Pop can lid pressure resistant testing device

Technical field

The utility model relates to cover of pop can voltage-withstand test technical field, especially a kind of pop can lid pressure resistant testing device.

Background technology

Pop can integral body is made by aluminum alloy materials, has conveniently to open, be easy to carry about with one and callable advantage, is widely used in industries such as beverage, can, milk powder, such as common canned Coca-Cola.In the national standard, the voltage endurance capability of pop can lid on the pop can there is certain requirement,, can causes lid to break, cause the liquid of inner splendid attire to reveal, even cause quick-fried spray if its compressive resistance is not enough.

At present, the structure such as the patent No. of the tester of test pop can lid compressive resistance commonly used are CN200920315559.8, name is called the disclosed content of patent of easy-open end Hi-pot Tester, as shown in Figure 8, comprise control box 6, collet 16 and lid clamping part, control box upper surface setting-in collet, the upper shed co-axial seal setting-in lid clamping part that drag at the end, a plurality of pressing plates 1 uniform control box upper surface that is arranged on the lid clamping part outside, the end of each pressing plate is crimped on the upper surface of lid clamping part, above-mentioned lid clamping part comprises lid holder 5 and loam cake 4, and the coaxial made boss 15 in loam cake bottom surface stretches in the lid holder and clamps the outer ledge of pop can lids with the made bulge loop 14 of lid holder inwall.In this structure, the gas of draft tube conveying 12 pushes lid from the below, when pressure oversteps the extreme limit, and the cover of pop can body deformability, the tester shuts down, the output of record display module.But in the said process, because loam cake and Gai Tuo clamp the pop can lid, do not simulate the true environment for use of pop can, so the result of test has deviation, deviation reaches 0.1MPa, when utilizing the existing equipment test in other words, data presented represents that the pop can lid is withstand voltage qualified, but in fact possibility dare not be qualified.。

And for example the patent No. is CN200920315558.3, name is called the disclosed content of Chinese patent of high precision pop can cover withstand voltage tester, its fundamental purpose is to improve test accuracy by the microswitch that increases, and loam cake and Gai Tuo clamp the pop can lid equally, also have the big problem of error.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low, safe in utilization and can accurately measure the pop can lid pressure resistant testing device of easy-open end voltage endurance capability.

A kind of pop can lid pressure resistant testing device, comprise control box, collet, loam cake and Gai Tuo, control module and collet are installed on the control box, the upper shed co-axial seal setting-in lid holder that drag at the end, the lid holder is gone up loam cake is installed, the uniform control box upper surface that is arranged on the loam cake outside of a plurality of pressing plates, the end of each pressing plate is crimped on the upper surface of loam cake, collet bottom setting-in draft tube, it is characterized in that: described loam cake bottom surface co-axial seal is inlaid in the lid holder, loam cake bottom surface and lid hold in the palm the movable pop can lid of installing in the cavity that forms between the made bulge loop of inwall, and the pressure transducer of a connection control module is installed on draft tube.

And, the coaxial annular boss of making in described loam cake bottom surface, this annular boss stretch in the lid holder and and described bulge loop upper surface between be provided with at interval, hold in the palm between the upper surface with lid in the loam cake bottom surface in the annular boss outside sealing ring is installed.

And, described control module comprises central control module, display module and key-press module, display module and key-press module are inlaid in the leading flank of control box, display module and key-press module all are connected the IO interface of the central control module of being adorned in the control box, and the IO interface of this central control module is mounted on the pressure transducer on the draft tube.

Advantage of the present utility model and beneficial effect are:

The utility model is simple in structure, cost is low, form a cavity between loam cake and the lid holder, the movable pop can lid of installing in this cavity, when draft tube is inflated, the pop can lid below be adjacent under the extruding of gas on the made annular boss in loam cake bottom surface, after the pressure of gas surpasses certain limit, the distortion that raises up of pop can lid, the space that produces will gush in the passage of gas in the middle of loam cake, a flex point appears in the pressure history that the pressure transducer of installing on draft tube is gathered, this flex point is the maximum pressure that the pop can lid can bear, said structure can accurately test out pressure value accurately, guarantee the quality and the consistance of appearance product, improved the accuracy of measuring.
