[0037] As Figure 1 shown, this embodiment provides a cigarette packing machine, which includes two symmetrically arranged cigarette pack transparent film folding devices for folding the transparent films at both ends of the cigarette pack.

[0038] Specifically, the cigarette pack transparent film folding device includes a folding block 1, a fixed block (not shown in the figure), and at least two adjusting components 2. A folding groove 12 extending in the first direction is provided on the first side wall 11 of the folding block 1 for folding the transparent film of the cigarette pack; a boss 14 is provided at the bottom of the folding block 1, and a second side wall 15 is provided on the side of the boss 14 close to the first side wall 11; the bottom of the folding block 1 is lapped on the top surface of the fixed block, and the boss 14 is located on one side of the fixed block; at least two adjusting components 2 are arranged at intervals in the first direction between the second side wall 15 and the side wall of the fixed block for adjusting the distance between the second side wall 15 and the side wall of the fixed block. During installation, the bottom of the folding block 1 is lapped on the top surface of the fixed block, and the distance between the second side wall 15 of the boss 14 and the side wall of the fixed block is adjusted through at least two adjusting components 2, thereby adjusting the relative position between the folding block 1 and the fixed block to make the first side wall 11 of the folding block 1 parallel to the end face of the cigarette pack and the first side walls 11 of the folding blocks 1 of the two cigarette pack transparent film folding devices parallel. The whole adjustment process is simple to operate and has high precision, without the need for repeated confirmation and adjustment. During processing, the transparent film of the cigarette pack slides into the folding groove 12, and the folding groove 12 folds the transparent film, improving the product quality and equipment efficiency.

[0039] Preferably, a chamfer 13 is provided at the feeding end of the folding groove 12 to guide the transparent film and facilitate the movement of the transparent film into the folding groove 12.

[0040] Specifically, the adjusting assembly 2 includes an adjusting bolt 21, an adjusting nut 22, and a first elastic member 23. The boss 14 is provided with at least two first through holes, and the first through holes correspond to the adjusting assembly 2 one by one. The adjusting bolt 21 passes through the first through hole and is threadedly connected to the adjusting bolt 21. The adjusting bolt 21 is provided with a head. The first elastic member 23 is disposed between the head and the second side wall 15, and one end of the head away from the second side wall 15 abuts against the side wall of the fixed block. When the screwing depth of the adjusting bolt 21 and the adjusting nut 22 is increased, the adjusting bolt 21 compresses the first elastic member 23 to reduce the distance between the second side wall 15 and the side wall of the fixed block. On the contrary, when the screwing depth of the adjusting bolt 21 and the adjusting nut 22 is decreased, under the action of the first elastic member 23, the adjusting bolt 21 is fixed to reduce the distance between the second side wall 15 and the side wall of the fixed block.

[0041] In this embodiment, the first elastic member 23 is a disc spring. The disc spring is sleeved on the rod portion of the adjusting bolt 21, and one end of the disc spring abuts against the head, and the other end abuts against the second side wall 15. The disc spring ensures the fixation of the adjusting bolt 21 and prevents the adjusting bolt 21 from moving in the first through hole.

[0042] Preferably, a connecting groove 16 is provided at the bottom of the boss 14. Two adjusting assemblies 2 are symmetrically disposed on both sides of the connecting groove 16. The connecting groove 16 is connected to the side wall of the fixed block through a fastener. In this embodiment, the fastener includes a screw rod and a fastening nut. The first end of the screw rod is connected to the fixed block, and the second end is embedded in the connecting groove 16 and extends out of the second side wall 15. The fastening nut is threadedly connected to the second end of the screw rod to realize the fixation of the folding block 1 and the fixed block, and the relative position of the folding block 1 and the fixed block is adjusted by the two adjusting assemblies 2.

[0043] Further, as Figure 1 and Figure 2As shown in the figure, the cigarette pack transparent film folding device further includes a support assembly 3. The support assembly 3 includes a support block 31 and a second elastic member 32. A groove 17 is provided on the first side wall 11. The groove 17 is located above the folding groove 12. The bottom end of the support block 31 is hinged to the groove 17 so that the support block 31 is in a first working position and a second working position. When the support block 31 is in the first working position, the top end of the support block 31 protrudes from the groove 17, and the bottom end of the support block 31 does not protrude from the groove 17. When the support block 31 is in the second working position, neither the top end nor the bottom end of the support block 31 protrudes from the groove 17. The second elastic member 32 is located between the support block 31 and the bottom of the groove 17. The second elastic member 32 is used to drive the support block 31 to the first working position. During processing, after the transparent film of the cigarette pack is folded by the folding groove 12, the end face of the cigarette pack fits against the first side wall 11. Then the cigarette pack moves upward. When passing through the support assembly 3, the end face of the cigarette pack abuts against the outer wall of the support block 31, driving the support block 31 to move from the first working position to the second working position against the elastic force of the second elastic member 32. At this time, the cigarette pack can pass through the support assembly 3 smoothly. After the cigarette pack passes through the support assembly 3, the support block 31 moves from the second working position to the first working position under the elastic force of the second elastic member 32. At this time, the part of the top end of the support block 31 protruding from the groove 17 supports the cigarette pack, facilitating the movement of the cigarette pack to the next working position.

[0044] In this embodiment, a hinge rod 33 is provided in the groove 17, and the support block 31 is rotatably connected to the hinge rod 33.

[0045] In this embodiment, the second elastic member 32 includes a first magnet 321 and a second magnet 322. The first magnet 321 is installed at the bottom of the groove 17. The second magnet 322 is located on the side of the support block 31 close to the bottom of the groove 17. The first magnet 321 and the second magnet 322 repel each other with the same polarity. The repulsive force between the first magnet 321 and the second magnet 322 can drive the support block 31 to move from the second working position to the first working position.

[0046] In other embodiments, the second elastic member 32 is a torsion spring. A hinge rod 33 is provided in the groove 17. The support block 31 is hinged to the hinge rod 33, and a torsion spring is provided between the support block 31 and the hinge rod 33. The elastic force of the torsion spring can drive the support block 31 to move from the second working position to the first working position.

[0047] Further, as Figures 1 - 3 shown, the cigarette pack transparent film folding device further includes an extension block 4. The extension block 4 is installed at the top end of the folding block 1. The extension block 4 is provided with an extension wall 41 flush with the first side wall 11. By providing the extension wall 41, multiple cigarette packs can be stacked above the support block 31. The extension wall 41 plays a role in stopping and blocking the end face of the cigarette pack, improving production efficiency.

[0048] In this embodiment, the extension block 4 is provided with a second through hole, and the top end of the folding block 1 is provided with a threaded hole. The screw passes through the second through hole and is threadedly connected to the threaded hole to fix the extension block 4 to the top end of the folding block 1. Since there is a gap between the screw and the second through hole, the installation accuracy of the extension block 4 is reduced. In this embodiment, the cigarette pack transparent film folding device further includes a positioning block 5. The positioning block 5 is installed on the folding block 1, and the side of the extension block 4 away from the extension wall 41 abuts against the positioning block 5 to prevent the extension block 4 from moving relative to the folding block 1 and improve the product quality.

[0049] Note that the above is only a preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments, and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention.
