Description

Crimping wrinkle detecting device

Technical field

The utility model relates to a kind of detecting device, especially relates to a kind of detecting device that detects can crimping wrinkle.

Background technology

Can is with the raw-food material after the treated seasoning, packs in the container through making behind the sealing high temperature sterilization, has long shelf-life, transport easy to carryly, edible easy, and is not subjected to season and the regional advantages such as restriction, liked by the consumer.It is not corrupt that tinned food can keep for a long time, is that container carries out high temperature sterilization after by vacuum seal, and food in the tank has been completely cut off and the contacting of outside air, and no longer is subjected to the pollution of microorganism.The can pack container generally all adopts tinplate to make, and the enclosuring structure of can all is the double seam formula, namely is to intervolve mutually between can body and the cover, finishes this process that intervolves by tin seamer.The pair of rollers can body of tin seamer is repeatedly done relative lift-over with the cover trip edge, makes the edge of the two because of flexural deformation, closely hooks together mutually and reaches sealing (such as Fig. 1).So the airtight quality of crimping is extremely important, be to guarantee the long-time most important condition of preserving of food.U.S. FDA proposes the can to America and Europe's outlet, and the overlap length of the crimping of can and overlap percent all must be greater than 50%, and wrinkle rating is less than 50%.Such as Fig. 1,2, shown in 3, crimping 8 is hooked together together by the body hook 61 of can body 6 and the lid hook 71 of cover 7, body hook 61 and lid hook 71 overlapping length are greater than more than 50% of width of body hook and lid hook, to be overlap length multiply by 100 and draw divided by the width of crimping 8 to overlap percent, lid hook 71 and hooking together of body hook 61 be formed by the extruding of roller groove overlapping, the definite size of covering width and the wrinkle rating of hook 71 of the radian of roller groove and cover round edge radian, the variation of the wearing and tearing of roller groove and cover round edge radian and tin seamer debugging are improper, easily cause and cover the rough wrinkles 9 in hook 71 edges (such as Fig. 4), make and cover hook 71 crimping out-of-flatnesses and the space occurs, affect the sealing property of crimping 8.The manufacturing enterprise of can outlet, in the can production run, cover can opening has regularly been set up in the detection of crimping 8 detected system, although the checkout equipment of crimping also has projection device, but it only is to detect overlap length and overlap percent, detection for wrinkle rating, checker and tin seamer adjustor are and the experience range estimation is determined, in the sealed cans process, wrinkle 9 shapes that crimping 8 produces are different, and range estimation is easy to cause erroneous judgement, in case error in judgement, the commodity inspection disqualified upon inspection, economic loss has not only also had a strong impact on the reputation of enterprise.

Summary of the invention

The purpose of this utility model is for existing problem, provides a kind of volume little, easy to carry, simple to operate, and precision is high, detects the detecting device of can crimping wrinkle rating.

In order to solve above-mentioned technical matters, the technical scheme that adopts is: a kind of crimping wrinkle detecting device, comprise housing, camera, the bottom inwall of described housing is provided with the detection groove of the placement crimping of perforation, detect the top of groove both sides, being provided with two is connected by screw rod and backstay movably, behind the mobile in opposite directions joint of these two backstays, its top, position that is affixed a little is provided with a camera, camera is connected with display screen on the housing through winding displacement, and the panel of display screen is marked with 0 to 100 rule.

Being affixed a little on same straight line of the center line of the rule on the described panel and two backstays.

The inner hole thread opposite direction of described two backstays, when the screw rod conrotatory turned, two backstays were mobile in opposite directions, and during the contrary rotation of screw rod, two backstays are oppositely mobile.

Inner chamber one side of described housing is provided with battery compartment.

The lateral wall of described housing is provided with the adjusting knob of regulating the camera focal length.

One end of described screw rod stretches out outside the housing, and in the outer end turning handle is housed.

After adopting above-mentioned utility model structure, the crimping of can is all disintegrated with combination pliers, detect in the groove there being the crimping that covers hook to be inserted into, the turning handle of rotating screw bolt, two backstays are moved and clamp and cover the hook both sides, lid hook and the camera of this moment are on the same straight line, namely cover 50 scale marks at the central point align display screens high scale chi center of hook width.Power-on, the lid hook projects on the image sensor surface by the photon image that camera lens generates, and then transfers electric signal to, becomes data image signal through analog to digital conversion, deliver to again processing processing in the digital signal processing chip, be transferred on the display screen by data bus again.Rotate adjusting knob and regulate the focal length of camera, make on the two edges alignment rule that covers the

hook image

0 and 100 scale mark, the crossing numerical value of the top of this shown lid hook wrinkle and rule on the display screen, it is exactly the ratio value that this wrinkle Extendible Extent accounts for whole lid hook length, wrinkle rating becomes corresponding relation with the crimping tight ness rating, wrinkle rating is less, and the expression tight ness rating is higher.If wrinkle rating greater than 50%, must be adjusted crimping.The utility model volume is little, and is easy to carry, simple to operate, and precision is high, and clear picture is fit to reviewer and tin seamer commissioning staff and uses.
