[0002] The segmented calendering conveyor for tobacco lining paper is mainly used in the tobacco packaging industry. Its purpose is to perform segmented calendering on the tobacco lining paper and achieve precise conveying to meet the quality and process requirements of tobacco packaging.

[0003] Tobacco packaging is a crucial component of the tobacco industry. As the packaging material that comes into direct contact with tobacco products, inner lining paper must not only possess excellent moisture-proof and aroma-preserving properties but also maintain a certain level of aesthetic appeal and processing adaptability. The application of segmented calendering and conveying technology helps improve the quality of inner lining paper and packaging efficiency, thus occupying an important position in the tobacco packaging industry.

[0004] When it is necessary to change to a different pattern or repair the worn roller surface, the movable embossing roller needs to be completely disassembled, resulting in a long replacement cycle and low maintenance efficiency. Therefore, there is an urgent need for an improved device that can achieve quick replacement of the embossing roller.

[0005] Furthermore, when adjustments are needed based on the thickness of the inner lining paper for different brands of cigarettes, existing equipment often cannot adjust the thickness and can only replace calendering parts of different diameters to adapt to the processing of inner lining paper of different thicknesses, which is inconvenient to use. However, existing calendering conveyor equipment is used in a certain way. Summary of the Invention

[0006] The purpose of this invention is to provide a segmented calendering and conveying device for inner lining paper, so as to solve the technical problems mentioned in the background art, such as the low replacement efficiency of existing inner lining paper calendering rollers and the inconvenience of adjusting the position according to different inner lining papers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] The segmented calendering conveyor for tobacco lining paper is mainly used in the tobacco packaging industry. Its purpose is to perform segmented calendering on the tobacco lining paper and achieve precise conveying to meet the quality and process requirements of tobacco packaging.

[0024] Tobacco packaging is a crucial component of the tobacco industry. As the packaging material that comes into direct contact with tobacco products, inner lining paper must not only possess excellent moisture-proof and aroma-preserving properties but also maintain a certain level of aesthetic appeal and processing adaptability. The application of segmented calendering and conveying technology helps improve the quality of inner lining paper and packaging efficiency, thus occupying an important position in the tobacco packaging industry.

[0025] Currently, when tobacco companies are embossing inner lining paper, they typically have multiple cigarette models, and the inner lining paper patterns for each brand are different. When processing one model of cigarette, and then switching to another model, different embossing rollers 202 are needed to process different inner lining papers. Furthermore, when changing to different patterns or repairing worn roller surfaces, the entire movable embossing roller needs to be disassembled. This results in long replacement cycles and low maintenance efficiency. Therefore, there is an urgent need for an improved device that can quickly change embossing rollers.

[0026] To resolve the above technical issues, please refer to Figures 1 to 5As shown, an embodiment of the present invention provides a segmented calendering and conveying device for inner lining paper, comprising two mounting plates 1, with two spindles 2 rotatably connected between the two mounting plates 1. The two spindles 2 are connected by a transmission mechanism 3. Two sets of positioning grooves 201 are provided on each spindle 2 along its axial direction. Two calendering rollers 202 are detachably connected to each spindle 2. Each calendering roller 202 is provided with multiple positioning elements 203 that can be inserted into the corresponding positioning grooves 201. A connecting element 204 is fixedly provided at one end of each calendering roller 202 near the mounting plate 1, and two corresponding connecting elements 204 are connected by bolts 205. The top spindle 2 is movable. The transmission mechanism 3 includes a first gear 301 set at one end of the spindle 2 extending out of the mounting plate 1. Two meshing second gears 302 are provided on the outer side of one of the mounting plates 1. The two second gears 302 mesh with the corresponding first gears 301 individually. Multiple mounting holes are provided on both mounting plates 1. Sliding members 103 are slidably provided on both mounting plates 1. A tensioning roller 104 is rotatably provided between the two sliding members 103. A second lead screw 105 is threadedly connected to both mounting plates 1. The second lead screw 105 is rotatably connected to the corresponding sliding member 103.

[0027] In use, the mounting plate 1 is installed on the corresponding cigarette equipment through the mounting holes and corresponding screws and other components. This technology is existing technology and will not be described in detail here. Two calendering rollers 202 mounted on the same spindle 2 form a cylindrical shape, thereby forming a complete calendering roller 202. When calendering and conveying the inner liner paper, the inner liner paper is located between the two complete calendering rollers 202. Grooves distributed along its axial direction can be opened on one of the calendering rollers 202. When the groove moves to the position directly opposite the inner liner paper, calendering is not performed at this position.

[0028] After stopping at this point, the conveying roller next to the calendering roller 202 can choose to continue conveying, or convey a short distance to move the position where calendering is not needed, so that the calendering roller 202 can continue to rotate, thereby achieving the effect of segmented calendering. This technology can be implemented using existing technology, such as using the control system of the corresponding equipment to realize the rotation and stopping of the mandrel 2, and the rotation and stopping of the conveying roller, to jointly control and achieve the effect of segmented calendering of the inner lining paper. The rotation and stopping of the conveying roller and the mandrel 2 are all based on existing technology and will not be described in detail here. The groove is set to leave a gap when the inner lining paper is conveyed and calendered, thereby achieving segmented calendering, which is not shown in the figure.

[0029] When the embossing roller 202 wears out, or when it is necessary to replace it with a different type of embossing roller 202, rotate the bolt 205 so that the bolt 205 and nut no longer restrict the connecting part 204. Then, remove the embossing roller 202 from the mandrel 2 so that the positioning part 203 moves out of the positioning groove 201. Then, install the new embossing roller 202 on the mandrel 2 so that the positioning part 203 on the new embossing roller 202 is inserted into the corresponding positioning groove 201. This prevents the embossing roller 202 from twisting or shifting during operation. The embossing roller 202, the positioning part 203, and the mandrel 2 are all made of rigid materials, which can meet the working requirements of not twisting or shifting during embossing.

[0030] Subsequently, the end faces of the two corresponding connectors 204 come into contact, and the contact position between the connector 204 and the spindle 2 is semi-circular, which can completely cover this part of the spindle 2. Friction pads and shock-absorbing pads can be added between the connector 204 and the spindle to reduce vibration during transmission and increase the stability of the connection between the spindle 2 and the connector 204. Then, the bolts 205 are used to fix the connector 204, completing the installation of the embossing roller 202.

[0031] During equipment operation, the motor drives one of the spindles 2, causing the corresponding calendering roller 202 to rotate. The spindle 2 at the bottom is driven by the first gear 301 to rotate the adjacent second gear 302. The second gear 302 drives another second gear 302 to rotate, and the other second gear 302 drives the top first gear 301 to rotate. The top first gear 301 drives the spindle 2 to rotate, thereby causing the top calendering roller 202 to rotate. This allows the inner lining paper located between the two calendering rollers 202 to be conveyed and calendered. The height of the tension roller 104 can be adjusted by rotating the second lead screw 105, which drives the sliding member 103 to move, thus adjusting the tension of the inner lining paper to different degrees.

[0032] By designing the calendering roller 202 to be individually detachable and separable, it can be replaced separately when the outer surface of the calendering roller 202 is worn or when different types of inner lining paper need to be changed. This allows for quick replacement when different types of inner lining paper need to be processed, thus avoiding the cumbersome steps of replacing the entire mandrel 2 and calendering roller 202, reducing replacement time, thereby reducing downtime and improving work efficiency.

[0033] Example 2

[0034] In actual use, it was found that when the thickness of the inner lining paper needs to be adjusted according to different brands of cigarettes, the existing equipment often cannot adjust the thickness. It can only replace the embossing parts of different diameters to adapt to the processing of inner lining paper of different thicknesses, which causes many inconveniences in use.

[0035] Based on the above embodiments, in order to solve the above technical problems, please refer to... Figures 1 to 5 As shown, the technical solution adopted includes a mounting plate 1, with a connecting plate 101 slidably mounted on each of the two mounting plates 1. The top spindle 2 is rotatably connected to the two connecting plates 101. Each mounting plate 1 is threadedly connected to a first lead screw 102, which is rotatably connected to the corresponding connecting plate 101.

[0036] Based on the above embodiments, when it is necessary to adjust the distance between the two ginning rollers 202 according to different cigarette types, the first lead screw 102 is rotated, and the first lead screw 102 drives the corresponding connecting plate 101 to move, thereby realizing the adjustment of the top mandrel 2. The adjustment process is a fine-tuning process. As can be seen from the attached drawings of the specification, when fine-tuning the top mandrel 2, the meshing between the corresponding first gear 301 and second gear 302 can still be guaranteed.

[0037] Furthermore, the first lead screw 102 can be replaced with an electric telescopic column, which is fixedly connected to the connecting plate 101. This allows the controller on the cigarette equipment to control the extension and retraction of the electric telescopic column, thus avoiding the inner lining paper that does not need to be embossed without creating grooves on the embossing roller 202. The extension and retraction accuracy of the electric telescopic column can be achieved by setting corresponding displacement sensors, etc. The feedback from the displacement sensors allows the controller of the cigarette equipment to control the extension and retraction of the electric telescopic column, thereby ensuring that the circular end faces of both ends of the top mandrel 2 are at the same horizontal plane and the same height, thus ensuring the accuracy of height adjustment.

[0038] By using the first lead screw 102 and the connecting plate 101, the height of the top mandrel 2 can be adjusted according to the different thicknesses of the inner lining paper of different types of cigarettes, thereby changing the distance between the two embossing rollers 202. This makes it suitable for processing inner lining paper of different thicknesses, without needing to change the diameter of the embossing rollers 202 according to the processing of inner lining paper of different thicknesses.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
