Install second articulated post 35 on the shell 31, still install apron 32 on the shell 31, apron 32 rotates through second articulated post 35 and installs on shell 31, has seted up logical groove 33 in the relative position of adjusting collar 603 on the apron 32, and the internal fixation of logical groove 33 is equipped with transparent plate 34, can observe the reading on the calibrated scale 601 through transparent plate 34, and the convenience is when not needing to adjust, and the interval between gyro wheel 25 and the lower gyro wheel 24 is gone up in audio-visual reading. The side of apron 32 still fixed mounting has handle 39, and the fixed mounting in the position of handle 39 has two dogs 308 on shell 31, and handle 39 card is established between two dogs 308, can be closed with apron 32, avoids external dust to get into adjusting collar 603, influences adjusting collar 603 precision.

In this embodiment, before use, the handle 604 is rotated to rotate the adjusting sleeve 603, and the adjusting shaft 26 moves up and down by matching with the adjusting column 72, the top block 611 and the first connecting block 271, so as to drive the adjusting frame 22 to move up and down, thereby completing the adjustment of the distance between the upper roller 25 and the lower roller 24; the indication groove 605 on the handle 604 is matched with the dial 601 to complete the display of the adjustment position of the adjusting bracket 22, that is, the distance between the upper roller 25 and the lower roller 24 can be obtained by the indication on the indication groove 605 and the dial 601;

after the adjustment is finished, the first motor 14 is started, the first motor 14 drives the first gear 15 to rotate, the first gear 15 drives the second gear 16 to rotate through the first belt 17, and therefore the rotating shaft 12 is driven to rotate, and the conveying belt 11 is driven to rotate; the second motor 4 is started, the second motor 4 drives the driving shaft 28 to rotate, the driving shaft 28 drives the fourth gear 281 to rotate, the fourth gear 281 is meshed with the third gear 254, so that the driven shaft 252 is driven to rotate, the upper roller 25 is driven to rotate, the driven shaft 252 drives the second belt 291 to rotate, the second belt 291 rotates to drive the first rotating shaft 241 to rotate, the lower roller 24 is driven to rotate, and therefore the rotating directions of the upper roller 25 and the lower roller 24 are opposite;

then, the preliminarily folded packing box is inserted between the two fixing strips 18 on the right side of the conveying belt 11, the packing box moves along with the fixing strips 18 and the conveying belt 11 until the folded part of the packing box enters between the lower roller 24 and the upper roller 25, and the packing box is extruded by the lower roller 24 and the upper roller 25 to complete the ink burst test and the ink falling test;

if the phenomena of ink explosion and ink falling do not occur in the primary experiment, the position of the upper roller 25 is adjusted again through the adjusting assembly 3, so that the distance between the lower roller 24 and the upper roller 25 is shortened, and then the secondary ink explosion test and the secondary ink falling test are performed on the packaging box;

the steps are repeated until the ink explosion phenomenon and the ink falling phenomenon occur at the crease of the packaging box, so that the packaging box is convenient and quick;

in the adjusting process, the adjusting shaft 26 drives the adjusting frame 22 to move downwards, the driven shaft 252 drives the third gear 254 to move downwards, the third gear 254 is meshed with the fourth gear 281, the driving shaft 28 extrudes the supporting rod 38 downwards, the supporting rod 38 extrudes the first spring 37, the first bearing 27 drives the third connecting block 91 to move, so that the sliding shaft 29 is driven to move in the sliding groove 304, the second belt 291 is kept tensioned, and meanwhile, the driven shaft 252 is prevented from tilting under the action of the second belt 291. When the adjusting frame 22 moves up and down under the action of the adjusting assembly 3, the meshing relationship between the third gear 254 and the fourth gear 281 does not change, i.e. when the distance between the lower roller 24 and the upper roller 25 changes, the synchronous movement between the lower roller 24 and the upper roller 25 with the same linear speed and opposite rotation direction can still be maintained.

The detection device for the cigarette packaging box provided by the invention is described in detail above. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
