Description

Air tightness detection device for cuboid material bag filled with granular materials

Technical Field

The utility model discloses an air tightness detection device of cuboid pocket of built-in granule material belongs to the packaging machinery field.

Background

As shown in the attached drawing 3, the granular materials are filled in the film bags and have certain fluidity, after the rectangular material bag A is vacuumized and sealed by heat, a blank section with a certain length is reserved at the bag opening part of the rectangular material bag A, the two film bags are attached together, the foremost end of the blank section is a heat sealing line 11, the film bags at the rectangular part tightly wrap the granular materials filled in the rectangular material bag under the action of atmospheric pressure, and therefore the material bag is kept to be rectangular. However, in actual production, the heat seal may leak, so it is necessary to detect whether the air tightness of the rectangular bag is good, and the bag with the problem of gas leakage needs to be removed off line, and cannot enter the subsequent process.

SUMMERY OF THE UTILITY MODEL

In order to detect whether the cuboid material bag filled with the granular materials has the air leakage problem, the utility model provides an air tightness detection device of the cuboid material bag filled with the granular materials, which comprises a conveyor 1, a side push cylinder 5 is arranged on the longitudinal beam on the left side of the conveyor 1, a side push plate 3 is arranged at the cylinder rod end of the side push cylinder 5, a detection vertical plate 10 is arranged at the rear end of the side push plate 3, a portal frame 2 is also connected on the longitudinal beams on the two sides of the conveyor 1, a normal position switch 4 is arranged on one side of the upper end of the portal frame 2, an air leakage position switch 6 is arranged on the right side of the normal position switch 4, the normal position switch 4 and the air leakage position switch 6 are both in the stroke range of the detection vertical plate 10, a side baffle cylinder 7 is arranged on the other side of the upper end of the portal frame 2, the cylinder rod of the side baffle cylinder 7 is hinged with the left end of a bent arm 8, a side baffle plate 9 is arranged at the right lower end of the bent arm 8, the middle part of the bent arm 8 is hinged on the portal frame 2, the air tightness detection device also comprises a control system, when the control system only receives the signal sent by the normal position switch 4, the air tightness of the cuboid material bag A is judged to be good, and when the control system also receives the signal sent by the air leakage position switch 6, the air tightness of the cuboid material bag A is judged to be not good.

The utility model discloses a theory of operation is: the cuboid material bag A subjected to vacuum heat sealing is conveyed to a detection position by the conveyor 1 and then stops, the side baffle cylinder 7 drives the side baffle plate 9 to swing downwards, the side push cylinder 5 drives the side push plate 3 to move towards the right side, the cuboid material bag A is tightly squeezed between the side baffle plate 9 and the side push plate 3, if the cuboid material bag A is not leaked, the detection vertical plate 10 reaches the sensing position of the normal position switch 4 and keeps still, the normal position switch 4 sends a signal to the control system, the control system judges that the side baffle plate 9 and the side push plate 3 return to reset, and the cuboid material bag A is continuously conveyed to the next working procedure; if cuboid pocket A's heat-seal effect is not good and the gas leakage phenomenon appears, push away under the extrusion of cylinder 5 at the side, cuboid pocket A will not keep its original shape, granule material will slide to fill to blank sack position in the bag, therefore side push pedal 3 will continue to move to the right side, drive the response position that detects riser 10 and reach gas leakage position switch 6, gas leakage position switch 6 will be to control system signals, it shows that this cuboid pocket A exists the gas leakage problem, 7 drive side shields 9 upswing of side shield cylinder are reset this moment, side push pedal 3 continues to move to the right side and push away conveyer 1 and make it roll off the production line with the cuboid pocket A of gas leakage.

The utility model has the advantages that: through the extrusion effect of the side baffle 9 and the side push plate 3 on the cuboid material bag A, the normal material bag and the air leakage material bag are different in overall dimension by utilizing the flowability of the particle materials filled in the normal material bag, the automatic detection and the automatic elimination of the air tightness of the cuboid material bag A are realized by utilizing different signals sent by the normal position switch 4 and the air leakage position switch 6, and the reliability of the vacuumizing heat sealing packaging unit is improved.
