Description
One, technical field
The utility model relates to packaging bag leak detection mechanism.
Two, background technology
At present; Soft pack is usually used in the packaging of liquid state, gaseous state, solid-state article; relate to several large fields such as food, medicine, biochemistry, washing; sealing intensity is the protection intensity of Soft pack to content; it is the critical nature of Soft pack; it directly affects the shelf-life of content, therefore detects extremely important to the sealing intensity of package.
At present, also not having special packaging bag leak detection equipment, is all that accuracy of detection is low, efficiency is poor by artificial observation and manual record, and inconvenient feedback in time detects data.
Three, summary of the invention
In order to overcome above defect, the utility model provides a kind of packaging bag leak detection mechanism, can detect the leak case of packaging bag fast accurately, and rejects underproof packaging bag in time.
The technical scheme that the utility model is taked is:
Packaging bag leak detection mechanism, it is characterized in that: comprise testing agency's body and at least 1 test chamber being arranged on body interior, have 1 backgauge parts and the conveying belt being arranged on test chamber bottom at least, test chamber and backgauge parts and conveying belt are synchronized with the movement, test chamber top is connected with vacuum pump, backgauge parts are arranged on the sidepiece of cavity, described backgauge parts are ratchet and cam combination interlock, each cam is worn on the same axis, realized rotating by axle band moving cam by ratchet, ratchet is controlled by cylinder, the every action of cylinder once, pawl wheel 90 degree.
The utility model test chamber lower end and conveying belt compress, and seal element adopts EPDM and conveying belt to seal, and below conveying belt, connect vacuum cavity, perforate is set up in the face that vacuum cavity contacts with conveying belt.
The utility model when test chamber and conveying belt compress packaging bag is sealed after, utilize vacuum pump to bleed and make the pressure of test chamber inside be less than atmospheric pressure, with this understanding, packaging bag internal pressure is greater than external pressure, packaging bag is caused to be expanded, the degrees of expansion of packaging bag, by sensor sensing, judges the leak case of packaging bag by sensor.
Sensor described in the utility model adopts pressure transducer.
Sensor described in the utility model adopts height sensor.
When detecting, cylinder controls test chamber and presses down to compress with conveying belt and ensure that cavity seals, and seal element employing EPDM and conveying belt seal.
The utility model conveying belt and test chamber utilize EPDM to seal, when test chamber vacuumizes, conveying belt may be inhaled in cavity under atmospheric pressure, for avoiding this situation, below conveying belt, (conveying belt fuselage) increases vacuum cavity, and its face contacted with conveying belt (require the conveying zone face relative smooth in this face and have certain toughness) increases perforate.When corresponding conveying belt stall detects, utilize vacuum pump to make conveying belt bottom negative pressure cavity reach certain vacuum tightness, ensureing that conveying belt underside gas pressure is less than or equal to conveying conveying belt upper strata pressure, avoiding conveying belt to tilt detecting the impact caused.
The beneficial effects of the utility model are: the utility model can detect the leak case of packaging bag fast accurately, and reject underproof packaging bag in time; The utility model equipment occupation space is little, accuracy of detection is high, detection efficiency is high.
Four, accompanying drawing explanation
Fig. 1 is the utility model packaging bag leak detection whole mechanism structural representation.
Fig. 2 is the utility model backgauge modular construction schematic diagram.
Fig. 3 is the utility model vacuum cavity structural representation.
Five, embodiment
Packaging bag leak detection mechanism, comprise testing agency's body and at least 1 test chamber 1 being arranged on body interior, have 1 backgauge parts and the conveying belt 3 being arranged on test chamber 1 bottom at least, test chamber 1 and backgauge parts and conveying belt 3 are synchronized with the movement, test chamber 1 top is connected with vacuum pump, backgauge parts are arranged on the sidepiece of cavity 1, described backgauge parts are ratchet 4, cam 5 and material blocking rod 7 combine interlock, each cam 5 is through on same axle 6, moving cam 5 is with to realize rotating by ratchet 4 by axle 6, ratchet 4 is controlled by cylinder, the every action of cylinder once, ratchet 4 rotates 90 degree.
The utility model test chamber 1 lower end and conveying belt 3 compress, and seal element adopts EPDM and conveying belt 3 to seal, and below conveying belt 3, connect vacuum cavity 8, perforate 9 is set up in the face that vacuum cavity 4 contacts with conveying belt 1.
Sensor is equipped with in test chamber inside described in the utility model, and described sensor is pressure transducer or height sensor.
The diameter of each cam described in the utility model is different, and each pawl wheel band moving cam rotates, and applies pressure respectively to material blocking rod.
The utility model when test chamber 1 and conveying belt compress packaging bag is sealed after, utilize vacuum pump and transitional cavity, bleed and make the pressure of test chamber 1 inside be less than atmospheric pressure; With this understanding, packaging bag internal pressure is greater than external pressure, causes packaging bag to be expanded.
Packaging bag is expanded and to pressure transducer certain pressure, can be processed by industrial computer to pressure transducer numerical value change, differentiates packaging leak case.
Data processing and basis for estimation: the material bag pressure increase of good seal is obvious, numerical value is comparatively large, and after rising, pressure remains unchanged.Seal bad material bag pressure increase not obvious, or numerical value is less, or has downtrending after rising.
The utility model can adopt height sensor to substitute pressure transducer, and packaging bag highly has lifting after expanding, by judging that the degree that material bag highly increases judges.
Height sensor can adopt various forms of displacement transducer.
Basis for estimation: the material bag height of good seal rises obviously, and numerical value is comparatively large, highly remains unchanged after rising.Sealing bad material bag height rises not obvious, or numerical value is less, or has downtrending after rising.
Ratchet cam mode is (for each cavity three backgauges, but be not limited to three backgauges): each cam design 4 phase places, wear on the same axis, above by ratchet straps moving axis and cam realize rotating (ratchet is controlled by cylinder, the every action of cylinder once, pawl wheel 90 degree), the diameter of each described cam is different, each pawl wheel band moving cam rotates, and applies acting force respectively, make it rise or fall material blocking rod; When 0, all striker plates are all packed up, and when 90 degree, first striker plate falls, when 180 degree, second striker plate falls (first striker plate keeps falling), when 270 degree, the 3rd striker plate falls (the first two striker plate keeps falling), 360 degree when being 0 degree, and all striker plates are packed up.Control like this controls the stopping of material;
The utility model cylinder control link mechanism, realizes the conversion of tangential movement and vertical motion, and is exaggerated stroke.
