The utility model has the advantages of simple structure, reasonable design, easy and reliable operation, good hermeticity, high testing accuracy, good repeatability and high operation efficiency, and can test a plurality of dimensions of pop-cans by one tester, thereby is a multi-functional pressure resistance tester for pop-can cap.

Description

Pop can cover withstand voltage tester

Technical field

The utility model belongs to instrument field, especially a kind of pop can cover withstand voltage tester.

Background technology

Advantages such as pop can is laborsaving, easy to carry because of its unlatching, transportation safety is not fragile, handsome in appearance and can reclaim again are widely used in industry, especially soda industries such as beverage, can, milk powder.Existing pop can mostly is the two piece can mode and makes, based on the splendid attire carbonated beverage, form certain pressure in tank interior, and the easy-open end on the pop can (being cover of pop can) is in manufacturing process, need through multi-step process such as riveting draw ring and the pre-grooves of compacting tongue piece, if grasp improper its voltage endurance capability that will certainly reduce; Particularly in summer high temperature period, the interior pressure of pop can increases relatively, if the compressive resistance of easy-open end is not enough, will inevitably cause easy-open end to damage, and beverage leaks, even forms quick-fried spray, and country has formulated the withstand voltage standard of easy-open end for this reason.Can't produce corresponding testing tool easy-open end is detected but at present China is domestic, though the easy-open end Hi-pot Tester is abroad arranged, but its sample splint is fixedly mounted on the tester, can not arbitrarily dismantle and change, and the size of the test chamber of each sample splint, shape are fixed.Therefore, the shortcoming of this tester is: the tester function ratio is more single, and each instrument can only be tested a kind of easy-open end of specification, and existing easy-open end has tens kinds of specifications, and this just needs tens kinds of testers accordingly, has correspondingly increased testing cost.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, good sealing effect, easy to operate easy, safe and reliable, degree of accuracy is high and can test the Hi-pot Tester of multiple different size cover of pop can.

The utility model is achieved through the following technical solutions:

This pop can cover withstand voltage tester, comprise control box, sample splint, gland and pressing plate, pressing plate is packed on the control box, it is characterized in that: be fixed with its bottom on the control box and be shaped on the pedestal that can be communicated with the pneumatic means in the control box, the sample splint of coaxial setting-in one hollow on this pedestal, the coaxial gland that is embedded with on this sample splint, two pressing plates are symmetricly set on the both sides of this gland, and pressing plate can be fitted on the gland.

And described pressing plate hinge is contained on the holder, the other end bottom of this pressing plate take put one with pneumatic jacking block that pneumatic means in the control box is connected on.

And gland is the hollow structure of flower shape, and pressing plate is fitted on the petal of this flower shape gland.

And formation one can be put the test chamber of cover of pop can between gland and the sample splint, at the sample splint inner edge place of this test chamber bottom one rubber ring is installed.

And, an O-ring seal is installed between sample splint and the pedestal.

Advantage of the present utility model and good effect are:

1. sample splint of the present utility model is removable, can take off from pedestal.When reality is tested, can use corresponding sample splint according to the diameter of tested cover of pop can, reached and used a tester can measure the purpose of plurality of specifications cover of pop can.

2. the utility model adopts cylinder locking gland, and is simple to operate, reliable, the poorly sealed problem of having avoided manually-operated to produce; Barometer reading adopts numeral to show tensimeter, and degree of accuracy height, intuitive are strong; When the cover of pop can of duplicate measurements unified specification, can pin and cover the internal pressure reduction valve, need not carry out re-adjustments to it, this has just reduced test period, has improved test efficiency.

3. the utility model is simple in structure, reasonable in design, operation is simple and reliable, good airproof performance, measuring accuracy height, good reproducibility, high efficiency, using a tester just can measure the cover of pop can of plurality of specifications, is a kind of multi-functional pop can cover withstand voltage tester.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, but is not limited to the concrete structure that present embodiment is narrated.

This pop can cover withstand voltage tester installs a back up pad 8 by bolt on its control box 9, is fixed with the pedestal 5 that a bottom is shaped on air admission hole 10 on this back up pad, and the pneumatic means (not shown) in this air admission hole and the control box is connected.The coaxial sample splint 3 that is embedded with a hollow on this pedestal can be installed an O-ring seal 13 that plays sealing function, with the pressure leakages that prevents that gas leak from causing between this sample splint and pedestal.Coaxially on this sample splint be embedded with a gland 2, gland is designed to flower shape; Form the test chamber 11 that to put cover of pop can between the made inner edge platform of this gland and sample splint,, a rubber ring 12 is installed on this inner edge platform in order to increase sealing property.This sample splint can have the test chamber of different-diameter according to the specifications design of different cover of pop can, when reality is tested, can choose corresponding sample splint according to the difference of cover of pop can, reach and used a tester can measure the purpose of plurality of specifications cover of pop can.

On the back up pad of gland both sides, be hinged with two pressing plates 1, front end bottom this holder of hinge dress of these two pressing plates by holder 6 symmetries; The other end bottom of this pressing plate take put one with pneumatic jacking block 7 that pneumatic means in the control box is connected on, but thereby an end of this pneumatic jacking block jack-up pressing plate when rising descends the other end of pressing plate.

The petal 4 of gland can be corresponding with the position of pressing plate top pressure head and be positioned under the pressing plate, so that pressing plate compresses gland; For the ease of observing the pressurized situation of cover of pop can, can on flower shape gland, open a through hole and form hollow structure.In actual production, can increase the quantity of pressing plate according to actual needs.

Principle of work of the present utility model is:

Energized will spend the shape gland to take off, and cover of pop can be faced up put into test chamber, buckle colored shape gland, and petal will be screwed under the pressure head of pressing plate.Outwards draw back cylinder control valve, cylinder drives the tail end jack-up of pneumatic jacking block with pressing plate, makes the pressure head of its front end tightly push down the petal of colored shape gland, and then pushes down the cover of pop can in the test chamber; To the test interacvity air-filling, the indicating value of observing digital display meter changes then, and persistent pressure is tested the taking-up cover of pop can that finishes to setting, and whether observe cover of pop can qualified.If repeatedly the cover of pop can of same specification is tested, can pin and cover the internal pressure reduction valve, needn't re-adjustments pressure.

Put into next cover of pop can, repeat above-mentioned process of the test.
