Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery and equipment, in particular to a container leakage detection device. Background Art

[0002] Container leak detection equipment includes high-voltage discharge leak detection or vacuum leak detection. The existing vacuum leak detection machine has low detection accuracy and cannot detect containers containing relatively viscous liquids; the existing high-voltage discharge leak detection machine generally uses an auger to transport the bottle body, and rotates the bottle body to detect leaks when passing between the bottle conveying bottom rail and the discharge detection mechanism. However, the existing high-voltage discharge leak detection machine can only be applied to smooth round bottles, but not to round bottles with rough surfaces. For example, when the leak detection object is a round bottle with mold ribs, the auger will easily jam the bottle during transportation, affecting the rotation of the round bottle, and the leaking part on the bottle body cannot be detected. Therefore, there is an urgent need for a high-voltage discharge leak detection machine that can comprehensively detect rough round bottles. Utility Model Content

Detailed implementation manners

[0028] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] An embodiment of the present utility model is a container leak detection device, including an inlet bottle wave wheel 1, an outlet bottle wave wheel 2, and at least two inclined wave wheels 3 disposed between the inlet bottle wave wheel 1 and the outlet bottle wave wheel 2. The inlet bottle wave wheel 1 and the outlet bottle wave wheel 2 are respectively connected to the vertical bottle positions on the inclined wave wheels 3. A detection mechanism 8 and a bottle rotating mechanism 7 are provided at the horizontal bottle positions on the inclined wave wheels. The bottle rotating mechanism 7 includes an outer bottle rotating belt 71 disposed outside the inclined wave wheel 3 and an inner bottle rotating belt 72 disposed inside the inclined wave wheel 3. The moving directions of the outer bottle rotating belt 71 and the inner bottle rotating belt 72 are opposite to each other for rotating the bottle.

[0030] In this embodiment, as Figure 1-2As shown, the inclined wave wheel 3 includes an inlet bottle inclined wave wheel 31, a transfer inclined wave wheel 33, and an outlet bottle inclined wave wheel 32 that are connected in sequence, all with a 45-degree bevel angle. The inlet bottle wave wheel 1 is connected to the vertical bottle position on the inlet bottle inclined wave wheel 31, the outlet bottle wave wheel 2 is connected to the vertical bottle position on the outlet bottle inclined wave wheel 32, a bottle body detection mechanism and a bottle rotating mechanism 7 are provided at the horizontal bottle positions of the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32, and a bottle top detection mechanism 83 is provided at the horizontal bottle position of the transfer inclined wave wheel 33.

[0031] In this embodiment, an inlet bottle auger 5 is further provided in front of the inlet bottle wave wheel 1, and an inlet bottle mesh belt 6 is provided on the inlet bottle auger 5. A plurality of grooves adapted to the bottle body are provided on the inlet bottle wave wheel 1 and the outlet bottle wave wheel 2.

[0032] In this embodiment, the horizontal bottle positions of the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32 are both located at the tops of the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32, the vertical bottle positions of the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32 are both located at the bottoms of the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32, and the horizontal bottle position of the transfer inclined wave wheel 33 is located at the bottom of the transfer inclined wave wheel 33.

[0033] Therefore, the movement trajectory of the bottle 4 is as follows: The bottle 4 enters the inlet bottle wave wheel 1 through the inlet bottle mesh belt 6 and the inlet bottle auger 5. The vertical bottle 4 rotates with the inlet bottle wave wheel 1 and enters the vertical bottle position at the bottom of the inlet bottle inclined wave wheel 31. The bottle 4 rotates with the inlet bottle inclined wave wheel 31 for half a turn and gradually inclines downward from the vertical, reaches the horizontal at the top of the inlet bottle inclined wave wheel 31, and then continues to rotate with the inlet bottle inclined wave wheel 31 for a quarter of a turn and gradually inclines upward, entering the transfer inclined wave wheel 33; then it gradually inclines downward as it rotates with the transfer inclined wave wheel 33 for a quarter of a turn, reaches the horizontal again at the bottom of the transfer inclined wave wheel 33, and then continues to rotate with the transfer inclined wave wheel 33 for a quarter of a turn and gradually inclines upward, entering the outlet bottle inclined wave wheel 32; then it gradually inclines downward as it rotates with the outlet bottle inclined wave wheel 32 for a quarter of a turn, reaches the horizontal for the third time at the top of the outlet bottle inclined wave wheel 32, and then continues to rotate with the outlet bottle inclined wave wheel 32 for half a turn and gradually inclines upward from the horizontal, reaching the vertical at the bottom of the outlet bottle inclined wave wheel 32; finally, it enters the outlet bottle wave wheel 2 from the vertical bottle position at the bottom of the outlet bottle inclined wave wheel 32 and enters different outlet channels according to the leak detection results.

[0034] In this embodiment, a protective fence 9 for protecting the bottle body is further provided outside the inlet bottle wave wheel 1, the outlet bottle wave wheel 2, and the inclined wave wheel 3.

[0035] Further, the bottle rotating mechanism 7 is as Figure 3As shown in the figure, it includes an outer rotary bottle belt 71 provided outside the inclined wave wheel 3 and an inner rotary bottle belt 72 provided inside the inclined wave wheel 3. The moving directions of the outer rotary bottle belt 71 and the inner rotary bottle belt 72 are opposite to each other, so as to rub the bottle body between the outer rotary bottle belt 71 and the inner rotary bottle belt 72 to rotate at a high speed, so as to detect leaks in the bottle body.

[0036] In this embodiment, the outer rotary bottle belt 71 is connected to an outer rotary belt driving mechanism. The outer rotary belt driving mechanism includes two driven wheels 72 and a driving wheel 73 around which the outer rotary bottle belt 71 is wound, and a driving wheel driving mechanism 75 connected to the driving wheel 73. The driving wheel 73 is driven by the driving wheel driving mechanism 75, and then the inner rotary bottle belt 72 is made to move around the driving wheel 73 and the driven wheels 72. The bottle body leak detection mechanism is located between the two driven wheels 72, and the two driven wheels 72 are at the same height, so that the inner rotary bottle belt 72 between the two driven wheels 72 is parallel to the bottle body, and the distance between the inner rotary bottle belt 72 and the outer rotary bottle belt 71 is less than the height of the bottle body when it is horizontal, so that the inner rotary bottle belt 72 can act on the bottle body horizontally and evenly, so that the opposite movements of the inner rotary bottle belt 72 and the outer rotary bottle belt 71 can rub the bottle body to rotate at a high speed.

[0037] In this embodiment, the inclined wave wheel 3 is connected to a wave wheel driving mechanism 35, and the inner rotary bottle belt 72 is connected to an inner rotary belt driving mechanism 76. The wave wheel driving mechanism 35 and the inner rotary belt driving mechanism 76 are integrated together, as Figure 4-5 shown.

[0038] When performing leak detection, the detection part should be covered by the solution in the bottle body. According to the movement trajectory of the bottle 4, the bottle body enters the inlet bottle wave wheel 1 vertically, and there is liquid at the bottom of the bottle body. A bottle bottom detection mechanism 81 can be set at any position of the inlet bottle wave wheel 1 to detect leaks at the bottle bottom. In this embodiment, the bottle bottom detection mechanism 81 is arranged at the right end of the inlet bottle wave wheel 1; according to the movement trajectory of the bottle 4, the bottle body first inclines upward on the transfer inclined wave wheel 33, then the bottle body is horizontal at the bottom of the transfer inclined wave wheel 33, and then inclines upward again. Therefore, only when the bottle body is horizontal at the bottom of the transfer inclined wave wheel 33, there is liquid at the top of the bottle body. The bottle top detection mechanism 83 can only be arranged at the horizontal working position of the bottle body on the transfer inclined wave wheel 33, that is, the bottom of the transfer inclined wave wheel 33; there is also a bottle rotating mechanism 7 at the horizontal working position of the bottle body on the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32. The inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32 can both be provided with a bottle body detection mechanism to detect leaks in the bottle body, but the detection electrode can only cover half of the bottle body. Therefore, the upper half bottle body detection mechanism 82 and the lower half bottle body detection mechanism 84 are arranged at the horizontal working position of the bottle body on the inlet bottle inclined wave wheel 31 and the outlet bottle inclined wave wheel 32 in sequence, and the positions of the upper half bottle body detection mechanism 82 and the lower half bottle body detection mechanism 84 can be exchanged.

[0039] In this embodiment, the detection mechanism 8 includes a bottom detection mechanism 81 of the bottle disposed on the bottle inlet rotary wheel 1, and a upper half bottle body detection mechanism 82, a top detection mechanism 83 and a lower half bottle body detection mechanism 84 at the horizontal station of the bottle body, which are successively disposed on the inlet inclined rotary wheel 31, the transfer inclined rotary wheel 33 and the outlet inclined rotary wheel 32. The positions of the upper half bottle body detection mechanism 82 and the lower half bottle body detection mechanism 84 can be interchanged. The detection mechanism 8 includes a bottle body leak detection electrode and a bottle body leak detection receiving electrode disposed opposite to each other, and the bottle body passes between the bottle body leak detection electrode and the bottle body leak detection receiving electrode.

[0040] In summary, through the above-mentioned container leak detection device, the following advantages are achieved:

[0041] (1) In the present utility model, the bottle is laid down through the transfer of the positive and inclined rotary wheels for detecting different parts of the bottle body and the bottle top, and the bottom of the bottle is detected when the bottle is upright, and then the bottle is upright and discharged, so as to realize the comprehensive detection of the bottle body and prevent missed detection;

[0042] (2) In the present utility model, the outer ring and the inner ring of the inclined rotary wheel are separately driven by power. Through the opposite movements of the inner rotary bottle belt on the inner ring of the inclined rotary wheel and the outer rotary bottle belt disposed outside the inclined rotary wheel, the bottle body located between the inner rotary bottle belt and the outer rotary bottle belt can rotate at a high speed even if there are mold clamping ribs, and the bottle will not be stuck due to the uneven surface, thereby improving the leak detection reliability, with a low missed detection rate, and realizing the comprehensive detection of the bottle body;

[0043] (3) The present utility model adopts high-voltage discharge leak detection, with high precision and can detect products with high viscosity.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it; although the embodiments of the present utility model are described in conjunction with the drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations fall within the scope defined by the appended claims.
