Abstract
The invention relates to a method for detecting the damage condition of the inner wall of a milk package through a polarizer. A product which is filled is drawn randomly on a filling production line, the package is opened, and aluminum foil on the inner surface of a package material is unfolded. The polarizer is overlapped on the aluminum foil. The color deviation of the surface of the aluminum foil is observed and is compared with that of the surface of the aluminum foil of the package material before use. If the color of the surface of the aluminum foil is obviously changed, a corresponding position is subjected to excessive high-temperature damage. The unique metallographic phase characteristic in the forming process of the aluminum foil on the surface of the package material is utilized, the characteristic of light rays reflected through the aluminum foil under the polarizer is observed, and whether the aluminum foil on the inner wall of the Tetra Pak package material is subjected to thermal damage or not and whether a machine runs abnormally and needs maintenance and adjustment or not are judged rapidly.
Description
Technical field
The method that the present invention relates to the damage of a kind of packaging material inner surface heat, particularly a kind of method detecting the damage of milk Tetra Pak inner surface heat, belongs to milk product packaging detection analysis field。
Background technology
Prior art scenario, the defect of prior art or deficiency:
The medicated pillow bag milk of Tetra Pak in the process of fill, packaging material be crimped in real time, the hot-forming long barrel shape structure obtained。The packaging material of long barrel shape structure are rapidly used for milk fill after high temperature hot pressing bonds, and then carry out corresponding high-temperature sterilization treatment。The use procedure of entire package material to be experienced high-temperature process again, the position of high-temperature process and time are desirable that high, any of flow process occurs that deviation is required for correcting timely, this will ask operator's variable interval on production line medicated pillow bag milk is inspected by random samples, finding machine to be made in heat anomaly occurs in medicated pillow handbag package material corresponding adjustment。
Prior art analyzes usually artificial sampling observation for the detection of medicated pillow handbag package material, operator randomly draws medicated pillow bag finished milk product, packaging material are taken apart, be positioned under microscope and inwall heat damage's situation of packaging material is carried out observation analysis。If the inwall of medicated pillow bag is subject to high temperature location or the time occurs abnormal, so can there is corresponding change in the surface metallographic of the aluminium foil layer of the inwall of packaging material, may determine that packaging material whether normal rolled, hot-forming and fill, sterilizing in packaging machine by microscopical observation。
The method that microscope is observed has good accuracy rate, it is also possible to reflect the running status of filling machine faster。But, still there is certain defect in microscope observational technique, mainly has 2 points:
Time one, microscope are observed, owing to the microscopical visual field is less, it is necessary to the packaging material that operator's continuous moving is taken apart are observed, to obtain the overall picture state of packaging material。
Two, microscope observational method must note the cleaning of camera lens at any time, once there be milky lotion to pollute camera lens on packaging material, whole observation process can become very difficult。
It addition, adopt the proficiency that the method that microscope is observed uses for microscope for operator to require higher, in observation process, operator are difficult to the running status diverting one's attention to note filling machine, are unfavorable for the safety standardization management of production line。
Summary of the invention
It is an object of the invention to: utilize microscope to observe the inconvenience existed in hot injury's process of Lile packaging material for prior art, it is provided that the method for a kind of quick detection milk Tetra Pak inner surface heat damage。The deflection refraction action of the light that the method reflects for aluminium foil surface mainly by polaroid, quickly finds hot injury's problem of packaging material。
To achieve these goals, the technical solution used in the present invention is:
A kind of method detecting the damage of Tetra Pak inner surface heat, randomly draws the product that fill completes on filling production lines, takes packaging apart, launched by the aluminium foil of packaging material inner surface。It is superimposed on it with polaroid, observes the color and luster deviation of aluminium foil surface through polaroid, contrast with the aluminium foil surface of normal packaging material, if change occurs in aluminium foil surface color and luster, be that corresponding position is subject to excessive high-temperature damage。
The method of the present invention utilizes metallographic feature unique in the aluminium foil forming process of package material surface, observes its color reflected through polaroid。The aluminium foil surface changed enters contrast with being heated, and the aluminium foil surface metallographic of heat damage changes, and under polaroid, serious change occurs in the gloss of reflection。Operator can quickly judge after taking packaging material apart whether packaging material are subject to abnormal high-temperature damage and which part receives the damage of high temperature, and then determines filling machine whether normal operation, if needs to be adjusted correspondingly。
In general, the color that the aluminium foil surface of normal packaging material reflects under polaroid is the color of silvery white (aluminium foil primary colors) superposition polaroid。When aluminium foil is subject to high-temperature damage time, can there is great change in its color reflected under polaroid, hence it is evident that is different from normal aluminium foil color and luster。Height according to temperature, the time length being heated etc. affects, in fact it could happen that the color such as aubergine, blueness。Site operation personnel has only to be superimposed upon one piece of polaroid the aluminium foil surface of packaging material, quickly can find whether packaging foil is subject to high-temperature damage by perusal。
As the preferred version of the present invention, polaroid is rectangular polaroid, and its size and Lilezhen bag shape adapt。Polaroid is mainly used for observing the aluminium foil situation of change of the inwall of Lilezhen bag in the present invention, it is only necessary to correspondingly sized polaroid can well realize observing accordingly work。And more than polaroid be also possible to composition burden。
As the preferred version of the present invention, described polaroid is duroplasts polaroid。Adopting duroplasts polaroid to have some strength, more convenient packaging material are deployed on it and observe accordingly。
As the preferred version of the present invention, the area of described polaroid is 20-200cm2。The size of the packaging bag according to Lilezhen bag milk arranges corresponding polaroid, it is achieved disposable complete observation, and minimum cost consumption。
Polaroid application in the aluminium foil surface hot injury of detection packaging material。
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
Whether 1, the inventive method adopts polaroid to replace traditional microscope observational technique, effectively raise staff on production line and check the efficiency of machine work state, it is possible to be abnormal on more convenient discovery machine。
2, the method for the present invention is owing to adopting polaroid to observe, without extra microscopie unit, save the detection equipment cost on production line, and can more quickly the abnormality of filling machine have been responded, reduce the abnormal impact for producing of machine。
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, the present invention is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain the present invention, be not used to limit。
Embodiment
On the Tetrapack medicated pillow bag filling production lines of plain chocolate, pouring process is randomly drawed medicated pillow by operator and is bundled into product, take packaging material apart, come open and flat for Lile packaging paper, put polaroid, observe whether the aluminium foil inside wrapping paper color and luster deviation occurs。If under polaroid the color and luster of aluminium foil with use before the color and luster of aluminium foil close or basically identical, then the packaging material of corresponding site are not affected by hot injury, and machine operation is normal。If if under polaroid, the color and luster of aluminium foil is dimmed, purpling, change paste, then corresponding position receives hot injury, judge which part of packaging material is thermally damaged then in conjunction with the aluminium foil surface color and luster situation of change analysis under the abnormal conditions detected in the past, it is necessary to further maintenance processes。
