[0024] In the initial state, the adjusting frame 2 is in the initial position, the return spring 3 is in the compressed state, the positioning rod 6 is locked by the locking member, the upper feeding roller 5 is away from the lower feeding roller 4, and the size of the feeding channel is relatively large. In use, the cigarette packaging paper is made to pass through the feeding channel and contact the lower feeding roller 4. The positioning rod 6 is unlocked by the locking member, the return spring 3 returns to a natural state, the adjusting frame 2 slides down to a near-limit position, and the adjusting frame 2 drives the upper feeding roller 5 and the positioning rod 6 to move down together. The upper feeding roller 5 contacts the cigarette packaging paper, the size of the conveying channel is reduced, and it automatically adapts to the thickness of the cigarette packaging paper. Then the positioning rod 6 is locked by the locking member, and the lower feeding roller 4 and the upper feeding roller 5 are driven to rotate synchronously in opposite directions by the driving member, thereby conveying the cigarette packaging paper.

[0025] In summary, this application allows for flexible adjustment of the feeding process for cigarette packaging paper according to its dimensions, improving adaptability and reducing the probability of paper jams and inaccurate feeding, thus meeting the needs of printing cigarette labels of different specifications and making it more practical.

[0026] like Figure 3As shown, in some embodiments, the locking element includes multiple clamping plates 7 that are slidably disposed on the frame 1 and abut against the positioning rod 6. The portion of the clamping plate 7 that abuts against the positioning rod 6 is arc-shaped. The multiple clamping plates 7 are slidably disposed in a horizontal direction and are arranged in a circular array. A tension spring 8 is provided between the clamping plate 7 and the frame 1. The tension spring 8 is horizontal and its two ends are fixedly connected to the clamping plate 7 and the frame 1, respectively.

[0027] Referring to the above, in the initial state, the locking screw 10 is threaded onto multiple clamping plates 7, which are close to each other and all abut against the positioning rod 6. Multiple tension springs 8 are all in a stretched state. The multiple clamping plates 7 together apply clamping force to the positioning rod 6, thereby locking the positioning rod 6. In use, the locking screw 10 is rotated away from the multiple clamping plates 7, and the multiple tension springs 8 return to their natural state. The multiple clamping plates 7 slide away from each other and away from the positioning rod 6 due to elastic potential energy, thereby unlocking the positioning rod 6. Conversely, the locking screw 10 is rotated until it is threaded onto the multiple clamping plates 7. During this process, the locking screw 10 first abuts against multiple guide cone surfaces 9. Through the transition action of the guide cone surfaces 9, the multiple clamping plates 7 are driven to slide synchronously to abut against each other and all abut against the positioning rod 6. The multiple tension springs 8 are stretched, thereby locking the positioning rod 6.

[0032] As shown in Figure 1 some embodiments, the lower feeding roller 4 and the upper feeding roller 5 are both provided with anti-skid lines 19;

[0033] With reference to the foregoing, when the lower feeding roller 4 and the upper feeding roller 5 feed together, the anti-skid lines 19 can increase the friction between the cigarette packaging paper and prevent slipping, so as to ensure the smoothness of the feeding process.

[0034] As shown in Figures 1-5 some embodiments, the rack 1 is provided with two limiting plates 20 in sliding manner, the limiting plates 20 slide in the horizontal direction, the rack 1 is provided with a forward and reverse screw rod 21 in rotating manner, the forward and reverse screw rod 21 is in the horizontal direction, the two limiting plates 20 are in thread fit with the forward and reverse thread segments of the forward and reverse screw rod 21 respectively;
