The diameter of the rotating sleeve 44 is larger than the width dimension of the first connecting plate 4 and the second connecting plate 41, the stop 22 is fixedly arranged on the fixed plate 2, when the first connecting plate 4 moves backwards, the sleeve 401 moves backwards, the fourth spring 406 recovers deformation and drives the second connecting plate 41 to move backwards, the second connecting plate 41 moves backwards to drive the mounting post 42, the clamping piece and the rotating sleeve 44 to move backwards, when the clamping piece is completely separated from the cigarette tail 72, at this time, the clamping piece extends out of the mounting post 42 through the action of the first spring 427, because the first connecting plate 4, the second connecting plate 41, the mounting post 42, the clamping piece and the rotating sleeve 44 continue to retreat, the rotating sleeve 44 is abutted against the stop 22, so that the transmission rod 403 extends in the sleeve 401 until the moving block 404 abuts against one end of the moving groove 402, the rotating sleeve 44 cannot rotate and cannot retreat during the process, when the transmission rod 403 is not extended any more but retreats together with the sleeve 401, the ball stud 405 moves on the internal thread 441 to drive the rotating sleeve 44 to rotate, so that the relative position of the transmission rod 403 and the internal thread 441 changes to return to the initial position, which is convenient for the transmission rod 403 to subsequently drive the rotating sleeve 44 to rotate.

The automatic coding machine comprises a machine body 21 and a spray head 211, wherein the spray head 211 is located below the fixing plate 2 and is 15-40mm away from the rotating wheel 12, so that the spray head 211 can print the two-dimensional code on the cigarette tipping paper 71 more accurately, the two-dimensional code can be sprayed, after the cigarette 7 is detected, the detection condition of the corresponding cigarette can be checked by scanning the two-dimensional code, and the automatic coding machine is convenient and rapid.

The application method of the embodiment comprises the following steps: when the cigarette clamping device is used, the motor 11 is started, the output shaft of the motor 11 drives the rotating wheel 12 to rotate, cigarettes 7 are transmitted to the placing groove 121 of the rotating wheel 12 through the transmission plate 5, when the placing groove 121 where the cigarettes 7 are placed rotates to the right above, the air cylinder 31 is started, the output shaft of the air cylinder 31 moves in the direction close to the second mounting plate 10, the first connecting plate 4 is driven to move forwards in the moving process of the output shaft of the air cylinder 31, the first connecting plate 4 moves forwards to extrude the fourth spring 406, so that the second connecting plate 41, the sleeve 401, the transmission rod 403, the mounting column 42, the rotating sleeve 44 and the clamping piece are driven to move forwards, when the first clamping block 43 and the second clamping block 430 in the clamping piece abut against one side of the rotating wheel 12, the tail cigarette 72 enters the first clamping hole 436, and as the output shaft of the air cylinder 31 continues to extend, the sliding blocks 431 on the first clamping block 43 and the second clamping block 430 slide towards the bottom of the groove 420 along the first sliding groove 422 and the second sliding groove 423, in the process, the tail part 72 of the common cigarette abuts against the bottom of the first clamping hole 436, the tail part of the middle cigarette abuts against the bottom of the second clamping hole 437, the tail part of the thin cigarette abuts against the bottom of the third clamping hole 438, so that the cigarette tipping paper 71 is completely within the range of the spray head 211 of the coding machine, when the first clamping block 43 and the second clamping block 430 completely enter the groove 420, the first clamping block 43 and the second clamping block 430 clamp the cigarette 7, the top of the mounting column 42 abuts against the rotating wheel 12, the output shaft of the air cylinder 7 continuously moves forwards, the first connecting plate 4 extrudes the fourth spring 406 and the sleeve 401, so that the bottom of the transmission rod 403 abuts against the bottom of the sleeve 401, the distance for the output shaft of the air cylinder 31 to move forwards is controlled, the distance for the transmission rod 403 to move forwards is controlled, at the moment, the sliding block 442 on the rotating sleeve 44 abuts against the limiting block 426, and the ball head column 405 on the transmission rod 403 is in threaded connection with the internal thread 441, enabling the transmission rod 403 to drive the rotating sleeve 44 to rotate for a quarter of a circle, so as to drive the mounting column 42, the first clamping block 43, the second clamping block 430 and the cigarette 7 to rotate for a quarter of a circle, starting the coding machine, enabling the spray head 211 to code the cigarette tipping paper 71, continuing to rotate for a quarter of a circle, and then coding until four surfaces of the cigarette tipping paper 71 are coded;

after the code printing is finished, the air cylinder 31 is started to retreat the output shaft of the air cylinder 31, in the retreating process, the output shaft of the air cylinder 31 drives the first connecting plate 4 to move backwards, the sleeve 401 moves backwards, the fourth spring 406 recovers deformation and elongates and drives the second connecting plate 41 to move backwards, the second connecting plate 41 moves backwards to drive the mounting post 42 and the rotating sleeve 44 to move backwards, the mounting post 42 moves backwards to enable the first clamping block 43 and the second clamping block 430 to extend out relative to the mounting post 42, when the first clamping block 43 and the second clamping block 430 extend out, the first clamping block 43 and the second clamping block 430 are loosened to loosen the cigarette tail 72, when the first clamping block 43 and the second clamping block 430 are completely separated from the cigarette tail 72, at the moment, the clamping piece cooperates with the first spring 427 to extend out the mounting post 42, and as the first connecting plate 4, the second connecting plate 41, the mounting post 42, the clamping piece and the rotating sleeve 44 continue to retreat, the rotating sleeve 44 is abutted against the stop block 22, so that the transmission rod 403 extends in the sleeve 401 until the moving block 404 abuts against one end of the moving groove 402, the rotating sleeve 44 cannot rotate and cannot retreat in the process, when the transmission rod 403 does not extend and retreats together with the sleeve 401, the ball-head column 405 moves on the internal thread 441 to drive the rotating sleeve 44 to rotate, so that the relative position of the transmission rod 403 and the internal thread 441 is changed and returns to the initial position, the transmission rod 403 subsequently drives the rotating sleeve 44 to rotate, the output shaft of the air cylinder 31 moves forwards for a certain distance to restore the deformation of the fourth spring 406, the motor 11 is started to drive the first cigarette which is finished to be coded to rotate, the cigarette 7 is transmitted along with the transmission belt 6, the placing groove 121 for placing the second cigarette reaches the right top, and the cigarette receiving paper 71 can be continuously coded by repeating the steps, the method is convenient and quick, and avoids the complexity of manual code printing.
