[0002] The main functions of a cigarette packaging machine include automatically completing the packaging film application, precise sealing, rapid adjustment, saving labor and time. Cigarette packaging machines can significantly improve production efficiency, reduce labor costs and intensity, ensure a neat and uniform packaging appearance, and enhance the product image.

[0003] After the packaging film is sealed, an easy-tear edge is usually set on the packaging film to facilitate tearing. A hole is punched in the easy-tear edge to form an easy-tear opening so that users can tear the packaging film along the easy-tear edge. However, the easy-tear edge opening of existing cigarette packaging machines is usually designed for specific specifications and sizes of products. The position of the easy-tear edge opening is relatively fixed, which still cannot improve the adaptability and flexibility of the production line. Moreover, the cutter head of the existing cigarette packaging machine is prone to dulling after a period of use, and the cutter head needs to be replaced frequently, which cannot guarantee the opening quality.

[0049] like Figures 1-4 As shown, this embodiment provides a punching mechanism for a cigarette packaging machine, which has a first direction X, a second direction Y, and a third direction Z that intersect each other.

[0050] In some implementations, the first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0051] In a specific embodiment, the punching mechanism of the cigarette packaging machine includes a frame, a drive assembly, a mounting plate 1, a first drive unit 3, and a cutter holder 4. The drive assembly is connected to the frame, the mounting plate 1 is connected to the drive assembly, and the drive assembly can drive the mounting plate 1 to move along a first direction X. The mounting plate 1 has a through-film window 11 extending along the first direction X. The first drive unit 3 is connected to the mounting plate 1, and the output end of the first drive unit 3 has a piston 32. The first drive unit 3 is configured to drive the piston 32 to move along a third direction Z. The cutter holder 4 is detachably connected to the piston 32. The blade holder 4 is provided with a blade head 41 for cutting the packaging film 100 on the side away from the piston 32. By setting a drive assembly, the mounting plate 1 can be driven to move along the first direction X, thereby adjusting the position of the blade head 41 in the first direction X. The position of the blade head 41 can be adjusted according to different specifications and sizes of products. Then, the first drive unit 3 drives the blade head 41 to move along the third direction Z to cut and punch holes in the packaging film 100. In addition, the blade holder 4 is connected to the piston 32, and different blade heads can be replaced at any time according to the size of the tear edge, improving the adaptability and flexibility of the cigarette packaging machine.

[0052] In some embodiments, to ensure the cutting and punching effect and protect the blade 41, the punching mechanism of the cigarette packaging machine also includes a support 5. The support 5 is connected to the mounting plate 1. The blade holder 4 and the support 5 are respectively located on opposite sides of the film-passing window 11 in the third direction Z. A buffer pad 51 is provided at the end of the support 5 facing the blade holder 4. The buffer pad 51 and the blade 41 are opposite each other in the third direction Z. When the first driving unit 3 drives the blade 41 to approach the buffer pad 51, it can make a cut at the easy-tear edge of the packaging film 100. The buffer pad 51 can protect the blade 41, extend the service life of the blade 41, and ensure the quality of product packaging.

[0053] Additionally, it should be noted that in the cigarette packaging machine, the frame is equipped with an unwinding mechanism and multiple conveyor rollers. Bundled packaging films are installed on the unwinding mechanism for unwinding. The unwound packaging film is then conveyed to a designated position by multiple conveyor rollers for product packaging. The packaging film can pass horizontally through the film window 11 along the second direction Y. During the cutting process of the cutter head 41, the packaging film 100 is in a static and taut state to ensure cutting accuracy.

[0054] In some embodiments, the film-passing window 11 has a semi-closed structure to meet the punching requirements of packaging films 100 of different widths. That is, it is only necessary to ensure that the side of the packaging film 100 with the easy-tear edge is placed inside the film-passing window 11, while the other side of the packaging film 100 is allowed to extend to the outside of the mounting plate 1. This setting can not only meet the requirements of the packaging film 100 passing through, but also adjust the position of the cutter head 41 according to the position of the easy-tear edge of the packaging film, so as to match the practicality of packaging films 100 of different sizes and improve applicability.

[0055] In some embodiments, to further improve the cutting and punching effect, the buffer pad 51 is provided with an opening that matches the shape of the blade head 41. The blade of the blade head 41 can be fitted into the opening along the third direction Z to cut the packaging film 100. The buffer pad 51 with the opening can cooperate with the blade head 41 to effectively cut and punch the easy-to-tear edge, thereby improving the punching efficiency and quality.

[0056] In some embodiments, the punching mechanism of the cigarette packaging machine also includes a bracket 2, which is detachably connected to the first drive unit 3 and the mounting plate 1, thereby enabling the first drive unit 3 to be quickly disassembled and assembled, which is beneficial for later maintenance and replacement.

[0057] In some embodiments, to further achieve position adjustment of the first drive unit 3 and ensure the accuracy of cutting and punching, the punching mechanism of the cigarette packaging machine also includes a first fixing member 22. The bracket 2 is provided with an adjustment slot 21 extending in the third direction Z. The first fixing member 22 passes through the adjustment slot 21 and is used to connect the bracket 2 and the mounting plate 1. The design of the adjustment slot 21 allows the bracket 2 to be adjusted relative to the mounting plate 1 in the third direction Z, thereby adjusting the position of the cutter head 41 to meet the cutting and punching requirements of packaging films of different specifications.

[0058] In some embodiments, the punching mechanism of the cigarette packaging machine further includes a second fixing member 31, which is used to connect the first drive unit 3 and the bracket 2 to facilitate the assembly and disassembly of the first drive unit 3 and the bracket 2.

[0059] In some embodiments, the first drive unit 3 is preferably a cylinder.

[0060] In some embodiments, the first fixing member 22 and / or the second fixing member 31 are bolt fasteners to facilitate the assembly and disassembly of the mounting plate 1, the bracket 2 and the first drive unit 3.

[0061] In some embodiments, the mounting plate 1 includes a connecting portion 12 and an extension portion 13 connected to the connecting portion 12. There are two extension portions 13, and the two extension portions 13 are disposed opposite each other at both ends of the membrane window 11 in the third direction Z. Further, the drive assembly includes a guide block 14 and a guide rail 15. The guide block 14 is disposed on the extension portion 13, and the guide rail 15 extends along the first direction X and is disposed on the frame. The guide block 14 is slidably disposed on the guide rail 15. The mounting plate 1 is moved in the first direction X by means of the guide block 14 and the guide rail 15, thereby realizing the position adjustment of the cutter head 41.

[0062] In some embodiments, to ensure the balance and stability of the mounting plate 1 in the first direction X, at least two guide blocks 14 are provided at intervals along the third direction Z in the extension 13. The number of guide rails 15 is the same as the number of guide blocks 14, and one guide rail 15 corresponds to one guide block 14.

[0063] In some embodiments, the drive assembly further includes a screw slider 16, a screw 17, and a second drive unit. The screw slider 16 is connected to the extension 13, and the screw 17 extends along the first direction X and is mounted on the frame. The screw slider 16 and the screw 17 are threadedly connected. The second drive unit is connected to the frame, and one end of the screw 17 is connected to the output end of the second drive unit. The second drive unit is configured to drive the screw 17 to rotate, so that the screw slider 16 can move along the first direction X, thereby driving the mounting plate 1 to move in the first direction X, and realizing precise adjustment of the cutter head 41 in the first direction X.

[0064] In some implementations, the second drive unit is preferably a servo motor to improve adjustment accuracy.

[0065] The working process of this utility model is as follows: Please refer to... Figures 1-4 After unwinding, the packaging film 100 passes through the film window 11 along the second direction Y. According to the position of the easy-tear edge of the packaging film 100, the second drive unit drives the screw 17 to rotate, causing the screw slider 16 to move along the first direction X. Then, the mounting plate 1 moves along the first direction X under the action of the guide block 14 and the guide rail 15 until the cutter head 41 and the easy-tear edge of the packaging film 100 are opposite each other in the third direction Z. The relative position of the bracket 2 and the mounting plate 1 in the third direction Z can also be adjusted by the first fixing member 22, thereby adjusting the position of the cutter holder 4 in the third direction Z to meet the packaging requirements of products of different specifications or sizes. After the adjustment, the first drive unit 3 drives the cutter holder 4 to move downward along the third direction Z through the piston 32, thereby driving the cutter head 41 to approach the buffer pad 51 to make a hole in the packaging film 100. After the hole is made, the first drive unit 3 drives the cutter head 41 to reset.

[0066] In summary, this utility model embodiment provides a punching mechanism for a cigarette packaging machine. By setting a driving component, the mounting plate 1 can be moved along the first direction X, thereby adjusting the position of the cutter head 41 in the first direction X. The position of the cutter head 41 can be adjusted according to different specifications and sizes of products. Furthermore, a semi-enclosed film-passing window 11 is opened on the mounting plate 1, which not only allows the packaging film 100 to pass through but also allows adjustment of the cutter head 41 position according to the position of the easy-tear edge of the packaging film, improving applicability. In addition, the cutter holder 4 is connected to the piston 32, allowing for the replacement of different cutters at any time according to the size of the easy-tear edge, improving the adaptability and flexibility of the cigarette packaging machine. A buffer pad 51 is provided at the end of the support 5 facing the cutter holder 4, and the buffer pad 51 is opposite the cutter head 41 in the third direction Z. When the first driving unit 3 drives the cutter head 41 close to the buffer pad 51, it can make a cut at the easy-tear edge of the packaging film 100. The buffer pad 51 can protect the cutter head 41, extend its service life, and ensure product packaging quality.
