Technical Field

[0001] This invention relates to the field of tobacco packaging machine technology, and more specifically, to a packaging platform adjustment device for a tobacco packaging machine. Background Technology

[0002] Tobacco is an annual herbaceous plant belonging to the genus Nicotiana in the family Solanaceae. Besides being used to make cigarettes, tobacco, pipe tobacco, and cigars for human consumption, tobacco also has various medicinal uses. The entire tobacco production process is quite complex, often designed as an assembly line. Tobacco packaging machines are mechanical equipment that can package tobacco products, greatly reducing the labor intensity of workers and significantly improving work efficiency.

[0003] Currently, since tobacco packaging is mostly long and narrow, when packaging and shipping, the cigarette packs usually need to be stacked together and then wrapped with film. However, during the use of existing tobacco packaging machine platforms, due to the significant differences in height and length between different types of cigarette packs, and the fact that their stacking procedures are often fixed, it is inconvenient to adjust them according to different types of cigarette packs. This makes it difficult to accurately achieve neat stacking of cigarette packs, which greatly affects the effectiveness of the equipment.

[0045] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0046] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0049] like Figures 1 to 15 As shown, an embodiment of the present invention provides a tobacco packaging machine packaging platform adjustment device, including: a cigarette conveying assembly 1, a fixed base 2, a rotating assembly 3, a cigarette stacking assembly 4, an extension assembly 5, and a lifting adjustment assembly 6.

[0050] The rotating assembly 3 includes a first motor 31 and a turntable 32. The first motor 31 is mounted on the top of the fixed base 2, and its output end is connected to the turntable 32. Specifically, the first motor 31 is used to drive the turntable 32 to rotate.

[0051] The cigarette stacking assembly 4 includes a storage slot 41, a movable seat 42, a fixing rod 43, a fixing plate 44, a shelf 45, and a first baffle 46. The storage slot 41 is symmetrically located at both ends of the turntable 32. The movable seats 42 are movably disposed within the storage slots 41. The fixing rods 43 are symmetrically disposed on the movable seats 42, passing through the first end of the movable seat 42 and the first end of the fixing plate 44 respectively. The fixing rods 43 are slidably connected to the movable seat 42 and fixedly connected to the fixing plate 44. The second end of the fixing plate 44 is connected to the first end of the shelf 45. The first baffles 46 are respectively disposed on both sides of the first end of the shelf 45. It should be noted that there can be one or more cigarette stacking assemblies 4. In this embodiment, there are two cigarette stacking assemblies 4, which are respectively disposed on opposite sides of the turntable 32.

[0052] The cigarette conveying assembly 1 is located on one side of the turntable 32 and is used to convey cigarettes to the shelf 45; the extension assembly 5 is located between the two movable seats 42 and is used to move the cigarette stacking assembly 4; the lifting adjustment assembly 6 is connected to the shelf 45 and is used to adjust the height of the shelf 45.

[0053] Specifically, the cigarette conveying assembly 1 conveys one pack of cigarettes onto the shelf 45. At this time, the lifting and adjusting assembly 6 moves the shelf 45 toward the fixed base 2. Then, the cigarette conveying assembly 1 conveys another pack of cigarettes onto the shelf 45, thus stacking the cigarettes on the shelf 45. When one cigarette stacking assembly 4 has finished stacking the cigarettes, the first motor 31 drives the turntable 32 to rotate, thereby aligning other cigarette stacking assemblies 4 with the cigarette conveying assembly 1.

[0054] During operation, the first motor 31 drives the turntable 32 to rotate, causing the turntable 32 to rotate the two cigarette stacking assemblies 4. The unloaded cigarette stacking assembly 4 rotates to the tail end of the cigarette conveying assembly 1, which then conveys the cigarettes to the shelf 45. The first baffle 46 provides a limiting function for the cigarettes, preventing them from slipping off the shelf 45. Simultaneously, the lifting and adjusting assembly 6 lowers the shelf 45, stacking the cigarette stacks on it. Once one cigarette stacking assembly 4 has finished stacking, the extension assembly 5 moves the movable seat 42 toward the center of the turntable 32, causing both cigarette stacking assemblies to move simultaneously toward the center of the turntable 32. Then, the first motor 31 drives the turntable 32 to rotate, aligning the other cigarette stacking assembly 4 with the cigarette conveying assembly 1, thus stacking the cigarettes sequentially.

[0055] This invention allows two stacking cigarette components 4 to switch between workstations, enabling a fully loaded shelf 45 to move the cigarette packs away for manual or robotic removal and transfer to another workstation for roll wrapping. The empty shelf 45 can then be transferred back to the cigarette pack conveying component 1 and the cigarette packs can be stacked again, thus achieving fast and accurate neat stacking of cigarette packs. The operation is simple and convenient, with strong applicability, improving the effectiveness of the device.

[0056] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 2 As shown, the cigarette conveying assembly 1 includes a frame 11, a conveyor 12 and a fixed frame 13. The frame 11 is located on one side of the turntable 32, and the conveyor 12 is located on the top of the frame 11 for conveying cigarettes. The fixed frame 13 is located on the top of the frame 11 and is located close to the cigarette stacking assembly 4.

[0057] A distance sensor 9 for detecting the height of cigarette strips is installed on the mounting bracket 13.

[0058] The present invention places the frame 11 on one side of the turntable 32, and the conveyor 12 on the top of the frame 11 for conveying cigarette packs; the fixed frame 13 is placed on the top of the frame 11 and close to the cigarette stacking assembly 4, and a distance sensor 9 for detecting the height of the cigarette packs is set on the fixed frame 13. By detecting the height of the cigarette packs by the distance sensor 9, the number of cigarette packs stacked on the shelf is kept consistent.

[0059] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 11 As shown, the lifting and adjusting assembly 6 includes a first cavity 61, a second motor 62, a first gear 63, a connecting plate 64, a first support column 65, and a first toothed plate 66. The first cavity 61 is disposed inside the movable seat 42. The second motor 62 is disposed inside the first cavity 61. The output end of the second motor 62 extends to the outside of the movable seat 42 and is connected to the first gear 63. The two ends of the connecting plate 64 are respectively connected to the two first baffles 46, and the connecting plate 64 is respectively disposed at the top and bottom of the first baffles 46. There are two first support columns 65, which are respectively disposed close to the two first baffles 46. The two ends of the first support columns 65 are respectively connected to the connecting plate 64. The first toothed plate 66 is disposed on the side wall of the first support column 65 and meshes with the first gear 63.

[0060] Specifically, under the rapid conveying of the conveyor 12, the first pack of cigarettes falls from the conveyor 12 and, with the obstruction of the first baffle 46, lands stably on the shelf 45. Simultaneously, the second motor 62 starts, driving the first gear 63 to rotate. The first gear 63 then drives the first toothed plate 66 to move, which in turn drives the first support column 65. The first support column 65 then lowers the shelf 45 via the connecting plate 64 and the first baffle 46. Each time a pack of cigarettes falls, the shelf 45 lowers by a certain distance, the height of which corresponds to the detected height of the cigarette pack. This allows the cigarette packs to be neatly stacked layer by layer on the shelf 45. The present invention uses the lifting adjustment component 6 to adjust the height of the shelf 45, facilitating the stacking of cigarette packs on it.

[0061] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 11 As shown, a material trough 48 is provided at the second end of the shelf 45, and the material trough 48 is located on both sides of the shelf 45.

[0062] The present invention provides a material trough 48 at the second end of the storage plate 45 and places the material trough 48 on both sides of the storage plate 45, so that after the cigarette packs are stacked on the storage plate 45, it is convenient for the operator to take out the stacked cigarette packs.

[0063] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 10 As shown, a stop 49 is fixedly provided at the bottom end of the fixing rod 43, and the diameter of the stop 49 is larger than the diameter of the fixing rod 43.

[0064] The present invention prevents the fixing plate 44 from falling off the fixing rod 43 by fixing a stop 49 at the bottom end of the fixing rod 43, and making the diameter of the stop 49 larger than the diameter of the fixing rod 43.

[0065] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, the extension component 5 includes a second cavity 51, a fourth motor 52, a second gear 53, a second support column 54, and a second toothed plate 55. The second cavity 51 is located in the middle position inside the turntable 32 and is connected to two receiving slots 41. The fourth motor 52 is located on the top of the turntable 32, and the output end of the fourth motor 52 extends into the second cavity 51 and is connected to the second gear 53. The second support columns 54 are symmetrically and slidably arranged on both sides inside the second cavity 51. The second toothed plates 55 are respectively arranged on the inner sidewalls of the two second support columns 54 and mesh with the second gear 53. The first ends of the two second support columns 54 are respectively fixedly connected to two movable seats 42.

[0066] Specifically, after the cigarettes on the shelf 45 of a stacking cigarette assembly 4 are stacked, the second gear 53 is driven to rotate by the fourth motor 52, so that the second gear 53 simultaneously drives the two second tooth plates 55 to move in opposite directions. Then the second tooth can drive the second support column 54 to move, so that the second support column 54 drives the movable seat 42 to move in the storage groove 41, thereby causing the movable seat 42 to drive the stacking cigarette assembly 4 to extend outward and abut against the conveyor belt of the conveyor 12.

[0067] The present invention drives the second support column 54 to move by the fourth motor 52, which in turn drives the movable seat 42 to move within the collection slot 41. This causes the stacked cigarette assembly 4 to move toward or away from the conveyor 12, thereby facilitating the replacement of multiple stacked cigarette assemblies 4 to collect cigarettes.

[0068] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 11 As shown, symmetrical limiting grooves 56 are provided on both sides of the inner wall of the second cavity 51, and the second end of the second support column 54 is fixedly connected to the limiting column 57, which is slidably fitted in the limiting groove 56.

[0069] The present invention provides symmetrically arranged limiting grooves 56 on both sides of the inner wall of the second cavity 51, so that the second end of the second support column 54 is fixedly connected to the limiting column 57. The limiting column 57 is slidably fitted in the limiting groove 56. By setting the limiting column 57 and the limiting groove 56, the second support column 54 can be limited to prevent the movable seat 42 from falling off the turntable 32.

[0070] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 13 As shown, the cigarette stacking assembly 4 also includes two second baffles 47, which are symmetrically arranged on both sides of the shelf 45.

[0071] The tobacco packaging machine's packaging platform adjustment device also includes a distance adjustment component 7, which is located at the bottom of the placement plate 45 and is connected to two second baffles 47 respectively. The distance adjustment component 7 is used to adjust the distance between the two second baffles 47.

[0072] This invention further limits the movement of cigarette packs onto the shelf 45 by symmetrically arranging two second baffles 47 on both sides of the shelf 45. The adjusting component 7 is located at the bottom of the shelf 45 and connected to the two second baffles 47 respectively. By adjusting the distance between the two second baffles 47 through the adjusting component 7, different types of cigarette packs can be stacked, thus improving the practicality of the tobacco packaging machine packaging platform adjustment device of this invention.

[0073] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 15 As shown, the adjustable distance assembly 7 includes a mounting plate 71, a threaded rod 72, a moving block 73, a third motor 74, a sliding groove 75, a sliding column 76, a connecting frame 77, and a connecting arm 78. The mounting plates 71 are symmetrically fixed at both ends of the bottom middle of the shelf 45. The threaded rod 72 is rotatably connected between the two mounting plates 71 through bearings. The moving block 73 is threadedly connected to the threaded rod 72. The third motor 74 is located at the bottom of the first end of the shelf 45, and the output end of the third motor 74 is fixedly connected to the threaded rod 72. The sliding groove 75 is located on both sides of the shelf 45 and extends towards the center of the shelf 45. The sliding column 76 is slidably located in the sliding groove 75, and the second baffle 47 is connected to the sliding column 76. The bottom of the sliding column 76 is connected to the first end of the connecting frame 77, and the second end of the connecting frame 77 is connected to the moving block 73.

[0074] Specifically, when it is necessary to change to a different type of cigarette pack, the third motor 74 is driven to rotate the threaded rod 72. Then, the threaded rod 72 drives the moving block 73 to move, which in turn drives the two connecting arms 78 to rotate. After that, the connecting arms 78 drive the sliding column 76 to slide in the sliding groove 75 through the connecting frame 77. This allows the sliding column 76 to drive the two second baffles 47 to move towards or away from each other. In this way, the distance between the two second baffles 47 can be adjusted according to the width of the cigarette pack, so that the cigarette packs can be accurately and neatly stacked. The operation is simple and quick, greatly improving the applicability of the device.

[0075] The present invention controls the spacing between the two second baffles 47 by adjusting the width of the cigarette packs to be placed on the placement plate 45, thereby enabling the tobacco packaging machine platform adjustment device of the present invention to collect different types of cigarette packs, effectively improving the practicality of the tobacco packaging machine platform adjustment device of the present invention.

[0076] In one embodiment of the tobacco packaging machine packaging platform adjustment device of the present invention, such as Figures 1 to 15 As shown, the tobacco packaging machine packaging platform adjustment device also includes a positioning component 8, which is disposed on the second baffle 47.

[0077] The positioning assembly 8 includes a cylinder 81, a slide rail 82, and a positioning plate 83. The cylinder 81 is located on the outside of the second baffle 47 and is fixed on the placement plate 45. The slide rail 82 is located on the second baffle 47 and extends along the length of the second baffle 47. The positioning plate 83 is slidably located in the slide rail 82. The cylinder 81 is connected to the positioning plate 83.

[0078] Specifically, after the cigarette packs on the shelf 45 are stacked to a set height, the positioning plate 83 can be driven by the cylinder 81 to slide in the slide rail 82, so that the positioning plate 83 moves up and down along the second baffle 47. Thus, the height of the positioning plate 83 can be adjusted according to the stacking height of the cigarette packs, so that the positioning plate 83 can be pressed tightly on top of the cigarette packs, thereby effectively positioning the loaded cigarette packs and greatly ensuring the stability and reliability of the stacked cigarette packs.

[0079] The operation procedure of the tobacco packaging machine packaging platform adjustment device of the present invention is as follows: Figures 1 to 15 As shown, during the operation, the cigarette packs are continuously conveyed by the conveyor 12, and when the cigarette packs pass through the fixed frame 13, the distance sensor 9 on the fixed frame 13 can measure the distance of the cigarette packs below to detect the height of the cigarette packs.

[0080] Next, the first motor 31 drives the turntable 32 to rotate, causing the turntable 32 to drive the two stacked cigarette components 4 to rotate, and causing the unloaded stacked cigarette components 4 to rotate to the tail end of the conveyor 12. At the same time, the fourth motor 52 drives the second gear 53 to rotate, causing the second gear 53 to drive the two second toothed plates 55 to move in opposite directions. Then, the second toothed plates 55 can drive the second support column 54 to move, causing the second support column 54 to drive the movable seat 42 to move within the receiving groove 41, thereby causing the movable seat 42 to drive the stacked cigarette components 4 to extend outward and abut against the conveyor belt of the conveyor 12.

[0081] Next, under the rapid conveyor 12, the first pack of cigarettes falls from the conveyor 12. With the obstruction of the first baffle 46 and the second baffle 47, the cigarettes land stably on the shelf 45. At the same time, the second motor 62 starts, causing the second motor 62 to drive the first gear 63 to rotate. Then, the first gear 63 drives the first toothed plate 66 to move, which in turn drives the first support column 65 to move. Afterward, the first support column 65 drives the shelf 45 to descend through the connecting plate 64 and the first baffle 46. Each time a pack of cigarettes falls, the height of the shelf 45 decreases by a certain amount. The height of the descent corresponds to the height of the detected cigarette pack, thus allowing the cigarette packs to be neatly loaded layer by layer on the shelf 45.

[0082] Next, by driving the third motor 74, the third motor 74 drives the threaded rod 72 to rotate. Then, the threaded rod 72 drives the moving block 73 to move, which in turn drives the two connecting arms 78 to rotate. After that, the connecting arms 78 drive the sliding column 76 to slide in the sliding groove 75 through the connecting frame 77. This allows the sliding column 76 to drive the two second baffles 47 to move towards or away from each other. In this way, the distance between the two second baffles 47 can be adjusted according to the width of the cigarette pack, so that the cigarette packs can be accurately and neatly stacked. The operation is simple and quick, greatly improving the applicability of the device.

[0083] Next, after the cigarette packs on the shelf 45 are stacked to the set height, the positioning plate 83 can be driven by the cylinder 81 to slide in the slide rail 82, so that the positioning plate 83 moves up and down along the second baffle 47. Thus, the height of the positioning plate 83 can be adjusted according to the stacking height of the cigarette packs, so that the positioning plate 83 can be pressed tightly on top of the cigarette packs, thereby effectively positioning the loaded cigarette packs and greatly ensuring the stability and reliability of the stacked cigarette packs.

[0084] Next, the first motor 31 is driven again, causing the fourth motor 52 to drive the turntable 32 to rotate. At the same time, the fourth motor 52 drives the second gear 53 to rotate in the opposite direction, causing the movable seat 42 to drive the two cigarette stacking components 4 to quickly retract and reset. This allows the turntable 32 to drive the two cigarette stacking components 4 to switch positions. That is, the fully loaded shelf 45 moves away with the cigarette packs, and the empty shelf 45 rotates back to the end of the conveyor 12. At this time, the cigarette packs stacked on the shelf 45 can be removed manually or by a robotic arm and moved to another position for roll film packaging. The empty shelf 45 can also be used to stack cigarette packs again. With the cooperation of the above structures, tobacco packaging can be achieved quickly and continuously. It is simple and convenient to use, highly applicable, and greatly improves the effectiveness of the device.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
