Description
Technical field
The present invention relates to electronic induction field, particularly relate to a kind of easy-open end scoring systems based on eddy-current heating.
Background technology
The definition of easy-open end be carved with the line of weakness of certain depth in advance and riveting has draw ring to open time the lid that can tear safely along line of weakness.It is a kind of anti-fake bottle lid preferably.Easy-open end difficulty is comparatively large, and a lot of enterprise had taken into full account false proof needs before use, just have employed the design of interchangeability difference when thus making, lid universal bad, therefore has certain anti-fake effect.Another anti-fake effect of easy-open end needs special equipment in use, thus uses the wine of easy-open end just fewer by counterfeit situation.
Can lid in the real canned food processing industry of easy-open end.Although easy-open end product sequence is a lot, generally all comprise: shaping → ring pull combination is covered on iron sheet → basis, and shaping → postprocessing working procedures → imaging vision detects → collect lid pack.
Easy-open end has circular and non-circular two large classes, and special-shaped easy-open end refers to non-circular easy-open end, as oval, square, the shape of a hoof etc.
Easy-open end is the use for can capping and unlatching, as the term suggests easily should open when practicality, therefore capping be carved with in advance the indentation of a degree of depth when processing lid, and riveting has draw ring, when opening like this, lid can be fully withdrawn along indentation.
For the cause of can edible safety, can not have before requiring lid complete to food consumption after packaging for foodstuff is in tank and get rusty, corrode, be used for doing easy-open end tinplate material be all generally will carry out coating processes process in advance, namely be coated with the corrosion resistant coating of last layer on the surface of tinplate material, such lid would not get rusty, corrode in packaged food process.
But the processing of line of weakness will destroy this coating film above lid undoubtedly, so lid must carry out coating PROCESS FOR TREATMENT after indentation.In order to can maximum open can be opened, track and the lid profile track of general line of weakness are similar, be lid profile track inside wait square line, so the easy-open end line of weakness of circle is circular, the track of special-shaped easy-open end line of weakness is also the similar figures of this abnormity.
Easily find out; easy-open end be bubble on the basic cover being coated with diaphragm, rivet over draw ring and the combination of groove that is pressed in advance; during use; draw ring is with a spot wobble; the olecranon of draw ring knocks against groove hard; then Pull ring cover is torn along groove from basic cover, due to easy to use, is seen everywhere at present.
The key that can the draw ring of easy-open end knock against groove easily hard is that whether the degree of depth of indentation is suitable.
If the degree of depth of indentation is higher, so the voltage endurance capability of pop can is very limited, cannot completing high temperature sterilization, being even likely directly torn when rocking.
If the degree of depth of indentation is on the low side, the opening force required for draw ring is bigger than normal, even sometimes cannot open, and easily occurs that the elderly cannot tear the phenomenon such as lid fracture in easy-open end, easy-open end tearing procedure, can not reach the object easily opened.
At present, the enterprise of domestic production easy-open end, in order to the uniformity of the indentation that ensures to uncap and stability, is all by offline inspection easy-open end width of nick usually, then shuts down that adjustment mold height realizes, and degree of regulation is lower.
Patent " easy-open end mark mould set " (application number: the 90202406.X applying date: 1990-03-02) discloses a kind of easy-open end mark mould set, comprise one and be fixed on patrix, a counterdie and an indentation stop on die shank, the periphery of described counterdie and described stop has some holes, the described stop overlayed successively on base plate and described counterdie to be fixed on described base plate with screw and described upper and lower mould center is aimed at.
As long as this patent selects the stop of appropriate size, just can guarantee the precision of the width of nick of easy-open end, in addition because patrix is designed to dismountable, make can pull down during patrix cutting edge rust to carry out sharpening, but the scale selection of stop itself is just very difficult, and such degree of regulation is very low.
In addition, adopt offline inspection and shut down the method adjusted, larger on the impact of product quality, production efficiency and percent defective.And such measuring and adjustation is consuming time more each time, on average gets off and needs half an hour, the defective work produced during this section can reach more than 1000.
Summary of the invention
Technical problem to be solved by this invention is for defect involved in background technology, provides a kind of easy-open end scoring systems based on eddy-current heating.
