[0032] This application proposes improvements and innovations, and presents the following embodiments.
[0033] In some implementations, please refer to Figures 1 to 5A cigarette pack paper folding structure 3 is provided. The folding structure 3 is used to fold a faceted cigarette pack paper 1. The cigarette pack paper 1 has a rectangular bottom surface 11. The bottom surface 11 has two first side edges and two second side edges. A first side surface 12 is fixedly connected to each first side edge. A first end surface 13 and a second end surface 14 are fixedly connected to the two second side edges respectively. A first top surface 15 and a second top surface 16 are fixedly connected to the first end surface 13 and the second end surface 14 respectively. The folding structure 3 is fixedly connected to a substrate 2. The folding structure 3 has a first bending member 31 for bending the first end surface 13 relative to the bottom surface 11 and a second bending member 32 for bending the first top surface 15 relative to the first end surface 13.
[0034] The bending of the bottom surface 11 and the first side surface 12, as well as the second end surface 14 and the second top surface 16, can be completed by other folding mechanisms 4, or by workers by hand, ultimately achieving the complete folding and shaping of the cigarette pack paper 1. The sheet-like cigarette pack paper 1 is placed on the folding mechanism 4, and the folding structure 3 and the folding mechanism 4 work together to fold the sheet-like cigarette pack paper 1 into a rectangle.
[0035] By placing the sheet-like cigarette pack 1 on the folding mechanism 4, the first bending member 31 bends the first end face 13 of the sheet-like cigarette pack 1 relative to its bottom face 11, and the second bending member 32 bends the first top face 15 relative to the first end face 13. Then, in conjunction with other folding mechanisms 4 or by manual bending, the first side face 12 is bent relative to the bottom face 11, and the second end face 14 and the second top face 16 are bent, thus finally achieving the folding of the cigarette pack 1.
[0036] Thanks to the folding structure 3 that assists in folding the cigarette pack, the bending of the two key surfaces of the cigarette pack paper 1 is automatically completed by the first bending component 31 and the second bending component 32. This frees workers from some repetitive manual folding, reducing labor intensity and fatigue, and also improving the folding efficiency of the cigarette pack paper 1.
[0037] The mechanical structure ensures that the angle and position of each bend are basically consistent, which helps to improve the overall neatness of the cigarette pack folding and the product appearance quality, and reduces defects caused by differences in manual operation.
[0038] In one embodiment, the folding structure 3 includes a bracket 33 and a slider 34; the slider 34 is fixedly connected to the substrate 2; the sliding end of the slider 34 is fixedly connected to the bracket 33; the first bending member 31 and the second bending member 32 are both fixedly connected to the bracket 33.
[0039] The first and second bending components 32 are integrated into a single module by the bracket 33. The structure is compact and has good rigidity, which can ensure that the two bending components maintain stable and coordinated relative positions during operation.
[0040] The entire folding structure 3 is connected to the base plate 2 via a slider 34, allowing for overall positional adjustment. This enables the module to adapt to cigarette packs 1 of different sizes or to be precisely aligned with different workstations on the production line, improving the equipment's versatility and ease of debugging.
[0041] In one embodiment, the first bending member 31 includes a first driving cylinder 311, a first rotating shaft 312, and a first folding plate 313; the first driving cylinder 311 is fixedly connected to the bracket 33, and the output end of the first driving cylinder 311 is connected to the first rotating shaft 312 in a transmission manner; the first rotating shaft 312 is rotatably connected to the bracket 33; one end of the first folding plate 313 is fixedly connected to the first rotating shaft 312, and the other end can be rotatably fastened to abut against the next-level folding mechanism 4 to bend the first end face 13 relative to the bottom face 11, and the first folding plate 313 is located at one end of the folding mechanism 4.
[0042] The first drive cylinder 311 (such as a motor) drives the first rotating shaft 312, which can provide stable and controllable rotational torque and angle, and realize the precision and repeatability of the bending action of the first end face 13.
[0043] The first folding plate 313 is designed to rotatably snap together and abut against the next stage mechanism. This not only completes the bending action, but also applies a holding force to the bent part to ensure that the crease is stable in subsequent processes, prevents springback, and improves the reliability of folding.
[0044] In one embodiment, the second bending member 32 includes a second drive cylinder 321, a second rotating shaft 322, and a second folding plate 323; the second drive cylinder 321 is fixedly connected to the bracket 33, and the output end of the second drive cylinder 321 is drively connected to the second rotating shaft 322; the second rotating shaft 322 is rotatably connected to the bracket 33; one end of the second folding plate 323 is fixedly connected to the second rotating shaft 322, and the other end can be rotatably fastened to abut against the folding mechanism 4 to bend the first top surface 15 relative to the first end surface 13.
[0045] The second bending component 32 is similar to the first bending component 31 (drive cylinder + rotating shaft + folding plate), realizing modularity and standardization in design, which helps to reduce manufacturing, assembly and maintenance costs.
[0046] The second bending element 32 is used to bend the first top surface 15 relative to the already erected first end surface 13, which is a crucial step in forming the three-dimensional package shape. The mechanized operation is fast and accurate, ensuring the forming quality of the top of the packaging.
[0047] In one embodiment, the bracket 33 includes a support member 331 and a support block 332 fixedly connected to the support member 331; the support member 331 is fixedly connected to the sliding end of the slider 34; the first bending member 31 and the second bending member 32 are both fixedly connected to the support member 331; a sliding track 333 is provided on the substrate 2, and the support block 332 is slidably connected to the sliding track 333.
[0048] The added support block 332 cooperates with the sliding track 333 on the base plate 2 to provide precise linear motion guidance for the entire bracket 33 module, which greatly enhances the load-bearing capacity and stability during movement, and prevents the module from shaking or shifting during operation.
[0049] The support block 332 distributes the weight and reaction force of the bracket 33 onto the solid base plate 2 track, improving the stress state of the structure and increasing the overall rigidity and service life of the equipment.
[0050] In one embodiment, the support member 331 includes a first plate 3311, a connecting block 3312, a second plate 3313, a first fixing block 3314, and a second fixing block 3315; one end of the first plate 3311 is fixedly connected to the sliding end of the slider 34, and the other end is fixedly connected to the support block 332; the bottom of the connecting block 3312 is fixedly connected to the first plate 3311, and the top is fixedly connected to the second plate 3313; the first fixing block 3314 is fixedly connected to the second plate 3313, and the first rotating shaft 312 is rotatably connected to the first fixing block 3314; the first drive cylinder 311 is fixedly connected to the first fixing block 3314; the second fixing block 3315 is fixedly connected to the top of the first fixing block 3314, and the second rotating shaft 322 is rotatably connected to the second fixing block 3315; the second drive cylinder 321 is fixedly connected to the second fixing block 3315.
[0051] Specifically, the first drive cylinder 311 is an electric motor, and the second drive cylinder 321 is a cylinder driven to rotate.
[0052] The hierarchical layout, from sliding connection to bending component installation, is achieved through components such as the first plate 3311, connecting block 3312, and second plate 3313. This design ensures clear force transmission, high space utilization, and a stable overall structure.
[0053] The first fixing block 3314 and the second fixing block 3315 provide dedicated and robust mounting bases for the drive cylinder and the shaft. The components are highly modular, which facilitates independent assembly, debugging and replacement maintenance.
[0054] In one embodiment, there are two first fixing blocks 3314 and two second fixing blocks 3315; the two first fixing blocks 3314 are spaced apart, and the two second fixing blocks 3315 are spaced apart. The spaced-apart first fixing blocks 3314 and second fixing blocks 3315 provide dual support points for the first rotating shaft 312 and the second rotating shaft 322, forming a stable "bearing seat" structure. This effectively prevents the rotating shafts from bending or vibrating under stress, ensuring smooth and precise movement of the folding plate and extending the lifespan of the rotating shafts and drive components.
[0055] In one embodiment, the sliding member 34 includes a fixed frame 341, a drive motor 342, a lead screw 343, a sliding block 344, and a slide rail 345; the fixed frame 341 is fixedly connected to the base plate 2, and the drive motor 342 is fixedly connected to the fixed frame 341; the output end of the drive motor 342 is drively connected to the lead screw 343; the lead screw 343 is rotatably connected to the fixed frame 341; the sliding block 344 is threadedly engaged with the lead screw 343, the sliding block 344 is slidably connected to the slide rail 345, the slide rail 345 is fixedly connected to the fixed frame 341, and the extension direction of the slide rail 345 is parallel to the extension direction of the lead screw 343; the bracket 33 is fixedly connected to the sliding block 344.
[0056] Employing a classic linear module design consisting of a drive motor 342, a lead screw 343, a slider 344, and a slide rail 345, it enables precise and controllable automatic adjustment of the overall position of the folding structure 3. It boasts high displacement accuracy and excellent repeatability.
[0057] The lead screw 343 provides good self-locking and smooth transmission; the slide rail 345 ensures load-bearing and guiding accuracy. This combination enables the sliding component 34 to withstand the load of the folding structure 3 during operation and maintain stability during high-speed or frequent movement, which is key to achieving cycle synchronization in automated production lines.
