[0042] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0043] During the operation of the ZB48 packaging equipment, the inner liner paper may malfunction and cause the machine to stop. After analysis, the inventor found that the main reason is that the inner liner paper pieces detach during the conveying process, which leads to abnormalities such as blockage, missing pieces, and deviation of the inner liner paper. At the same time, the detached inner liner paper pieces may also get stuck inside the cigarette pack, which greatly increases the product quality risk.

[0044] like Figures 1-5As shown, the intermittent tensioning conveying and cutting device for inner lining paper provided in this embodiment includes: a first guide roller assembly 3, an inner lining paper embossing device 9, an intermittent tensioning roller 7, an inner lining paper cutting roller 4, and an inner lining paper adsorption roller 5 arranged sequentially; the first guide roller assembly 3 is close to the inner lining paper roll 1; the inner lining paper embossing device 9 is used to extrude the inner lining paper 2 into embossed inner lining paper 8, and the inner lining paper embossing device 9 includes an embossing driven roller 91 and an embossing driving roller 92, the embossing driven roller 91 and the embossing driving roller 92 rolling in opposite directions. The embossing drive roller 92 is connected to an embossing drive roller drive gear 93; the intermittent tension roller 7 is used to tension and relax the embossing inner lining paper, and the intermittent tension roller 7 includes a first bridge gear 71, a second bridge gear 72 and an intermittent tension roller drive gear 73; wherein, the embossing drive roller drive gear 93 and the first bridge gear 71 mesh and drive each other; the first bridge gear 71 and the second bridge gear 72 mesh and drive each other; the second bridge gear 72 and the intermittent tension roller drive gear 73 mesh and drive each other.

[0045] The first paper guide roller assembly 3 includes a plurality of first paper guide rollers. It should be noted that the present invention does not specifically limit the number and distribution of the second paper guide rollers.

[0046] Furthermore, the outer surface of the inner lining paper cutting roller 4 is provided with a first vacuum adsorption hole, through which the inner lining paper cutting roller 4 adsorbs the embossed inner lining paper and rotates the embossed inner lining paper into shape; the outer surface of the inner lining paper adsorption roller 5 is provided with a second vacuum adsorption hole.

[0047] Furthermore, the inner liner paper cutting roller 4 cuts by shearing; as... Figure 2 and Figure 3 As shown, the inner lining paper cutting roller 4 includes an inner lining paper dotted line cutting knife 41 and an inner lining paper separation cutting knife 42. The inner lining paper dotted line cutting knife 41 is used to cut the dotted lines of the embossed inner lining paper when the embossed inner lining paper is rotated and formed, and the inner lining paper separation cutting knife 42 is used to separate and cut the embossed inner lining paper when the embossed inner lining paper is rotated and formed.

[0048] Furthermore, the intermittent tensioning roller 7 is connected to the intermittent tensioning roller drive gear 73 via a drive shaft, as shown below. Figure 4 As shown, the intermittent tension roller 7 has a groove at its bottom; the intermittent tension roller 7 is fastened to the drive shaft by two screws; furthermore, the intermittent tension roller 7 is fastened to the drive shaft by two screws, and the screws can be loosened to adjust the relative position of the drive shaft and the intermittent tension roller 7, which facilitates the corresponding adjustment of the phase of the intermittent tension roller 7 and the inner liner paper cutting roller 4.

[0049] Furthermore, such as Figures 1-3As shown, the intermittent tension roller 7 is connected to the inner liner paper cutting roller 4 through the second paper guide roller assembly. The second paper guide roller assembly includes multiple second paper guide rollers. It should be noted that the present invention does not specifically limit the number and distribution of the second paper guide rollers.

[0050] Furthermore, the power for the intermittent tensioning roller 7 is derived from the drive gear 93 of the embossing drive roller. Specifically, as... Figure 5 As shown, the intermittent tensioning roller drive gear 73 achieves synchronous operation with the embossing drive roller drive gear 93 through the transmission of the first bridge gear 71 and the second bridge gear 72.

[0051] Among them, such as Figure 5 As shown, the first bridging gear 71 has the same number of teeth as the embossing drive roller drive gear 93; the second bridging gear 72 has the same number of teeth as the first bridging gear 71; and the intermittent tension roller drive gear 73 has the same number of teeth as the second bridging gear 72. Therefore, the number of teeth of the embossing drive roller drive gear 93, the first bridging gear 71, the second bridging gear 72, and the intermittent tension roller drive gear 73 are all equal, so as to achieve a 1:1 transmission between the embossing drive roller drive gear 93 and the intermittent tension roller drive gear 73, thereby ensuring that the intermittent tension roller 7 is normally tensioned during the normal feeding of the inner lining paper. After the inner lining paper 2 is cut by the dotted line, the inner lining paper 2 is instantly relaxed and kept in a relaxed state before separation and cutting. The tension is restored the instant the inner lining paper separation and cutting blade 42 cuts.

[0052] The intermittent tensioning roller 7 of this invention employs an intermittent tensioning method for the inner liner paper. During normal inner liner paper feeding, it is normally tensioned. After the inner liner paper is cut along the dotted line, it is momentarily relaxed and held in a relaxed state until the separation cut. The tension is restored the instant the separation cutter makes the cut. This tensioning and relaxation of the inner liner paper controls the longitudinal tension, ensuring that the longitudinal tension is less than the tear-joint force between the dotted line cut and the forming cut. This prevents the tear-joints from detaching, reducing the number of cigarette packs rejected due to inner liner paper detachment. It also reduces liner paper blockage caused by detachment, thus minimizing equipment downtime, improving equipment efficiency, and preventing damage to equipment components due to frequent liner paper blockage.

[0053] The intermittent tensioning and conveying cutting device for inner lining paper provided in this invention is ingeniously designed, simple in structure, and highly practical. It enables the inner lining paper to be intermittently tensioned during conveying and cutting. By controlling the tension and relaxation of the inner lining paper, the longitudinal tension is controlled, ensuring that the longitudinal tension is less than the tearing force of the inner lining paper during the period from the dotted line cutting to the forming cutting. This prevents the tearing of the inner lining paper from detaching, reducing the number of cigarette packs rejected due to inner lining paper detachment, thereby reducing inner lining paper consumption and cigarette consumption. It also reduces the phenomenon of inner lining paper blockage caused by detachment, thus reducing equipment downtime, improving equipment efficiency, ensuring product quality, and preventing damage to equipment components due to frequent inner lining paper blockage, extending the service life of equipment components.

[0054] like Figure 6 As shown, the intermittent tensioning, conveying, and cutting method for inner lining paper provided in this embodiment includes the following steps in actual implementation:

[0055] Step S1: The inner lining paper 2 is extruded into shape by the inner lining paper embossing device 9 to become embossed inner lining paper 8, and the embossed inner lining paper is conveyed to the intermittent tension roller 7.

[0056] In one embodiment of the intermittent tensioning conveying and cutting method for inner lining paper of the present invention, step S1 may specifically include:

[0057] Step S11: Unroll the inner liner paper roll 1 using the guide roller 3, so that the inner liner paper 2 is fed into the inner liner paper embossing device 9 via the first guide roller assembly 3 (e.g., ...). Figure 1 (As shown).

[0058] Step S12: The inner lining paper 2 is extruded and shaped by the embossing driven roller 91 and embossing active roller 92 in the inner lining paper embossing device 9, becoming the embossed inner lining paper 8 (e.g., Figure 1 (As shown).

[0059] Step S13: The embossing driven roller 91 and the embossing driving roller 92 in the inner lining paper embossing device 9 convey the embossed inner lining paper downward to the intermittent tension roller 7 (e.g., ...) through friction. Figure 1 (As shown).

[0060] Step S2: After passing through the intermittent tension roller 7, the embossed inner lining paper 8 is adsorbed onto the inner lining paper cutting roller 4, and the embossed inner lining paper is cut with dotted lines and separated on the inner lining paper cutting roller 4.

[0061] like Figure 5As shown, the embossing drive roller drive gear 93 is driven by the first bridge gear 71 and the second bridge gear 72, synchronously driving the intermittent tension roller drive gear 73 to rotate, thereby realizing the synchronous rotation of the embossing drive roller 92 and the intermittent tension roller 7; in one embodiment of the intermittent tensioning conveying and cutting method for inner lining paper of the present invention, step S2 may specifically include:

[0062] Step S21: After passing through the intermittent tension roller 7, the embossed inner lining paper 8 passes through the second guide roller assembly and is adsorbed onto the inner lining paper cutting roller 4 by the vacuum effect of the first vacuum adsorption hole on the outer surface of the inner lining paper cutting roller 4.

[0063] Step S22: The embossed inner lining paper rotates clockwise with the inner lining paper cutting roller 4, and the dotted line cutting of the embossed inner lining paper 8 is completed by the inner lining paper dotted line cutting knife 41, and the separation cutting of the embossed inner lining paper 8 is completed by the inner lining paper separation cutting knife 42.

[0064] Step S3: During the cutting process of the inner liner paper cutting roller 4, the longitudinal tension of the inner liner paper 2 is controlled by the tensioning and relaxation of the inner liner paper 2, so that the longitudinal tension of the inner liner paper during the period from the inner liner paper dotted line cutting to the inner liner paper forming cutting is less than the inner liner paper tearing bond force.

[0065] In one embodiment of the intermittent tensioning conveying and cutting method for inner lining paper of the present invention, step S3 may specifically include:

[0066] Step S31: The intermittent tension roller 7 rotates clockwise, maintaining normal tension during the normal feeding of the embossed inner lining paper 8 (e.g., Figure 1 (As shown).

[0067] Step S32: The intermittent tension roller 7 rotates clockwise, and the embossed inner lining paper 8 is instantly released after the inner lining paper dotted line cutting knife 41 cuts it (as shown in the image). Figure 2 (As shown).

[0068] Step S33: The intermittent tension roller 7 rotates clockwise, and the embossed inner lining paper 8 is instantly tensioned after the inner lining paper separation cutter 42 cuts it (e.g., ...). Figure 3 (As shown).

[0069] This invention controls the longitudinal tension of the inner liner paper 2 by tensioning and relaxing the inner liner paper 2, so that the longitudinal tension of the inner liner paper is less than the bonding force of the inner liner paper tear pieces during the period from the inner liner paper dotted line cutting to the inner liner paper forming cutting, thus ensuring that the inner liner paper tear pieces will not detach.

[0070] Step S4: The inner lining paper adsorption roller 5 uses vacuum adsorption to cut and shape the embossed inner lining paper 8, and rotates counterclockwise to transport the cut and embossed inner lining paper to the cigarette pack packaging position (e.g., Figure 1 (As shown).

[0071] The inner lining paper adsorption roller 5 adsorbs the cut and shaped embossed inner lining paper 8 through the vacuum effect of the second vacuum adsorption hole provided on the outer surface of the inner lining paper adsorption roller 5.

[0072] In step S5, the cigarette pack 6 moves from right to left, passes under the inner lining paper adsorption roller 5, and is then wrapped and folded into shape by the embossed inner lining paper 8.

[0073] Specifically, such as Figure 1 As shown, the cigarette pack 6 moves from right to left, is wrapped and folded into shape by the embossed inner lining paper 8, and then proceeds to the next process.

[0074] The intermittent tensioning and conveying cutting method for inner lining paper provided in this invention is ingeniously designed, simple in structure, and highly practical. It enables the inner lining paper to be intermittently tensioned during conveying and cutting. By controlling the tension and relaxation of the inner lining paper, the longitudinal tension is controlled, ensuring that the longitudinal tension is less than the tearing force of the inner lining paper during the period from the dotted line cutting to the forming cutting. This prevents the tearing of the inner lining paper from detaching, reducing the number of cigarette packs rejected due to inner lining paper detachment, thereby reducing inner lining paper consumption and cigarette consumption. It also reduces the phenomenon of inner lining paper blockage caused by detachment, thus reducing equipment downtime, improving equipment efficiency, ensuring product quality, and preventing damage to equipment components due to frequent inner lining paper blockage, extending the service life of equipment components.
