Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing equipment, and more particularly to a device for conveying cut cigarette packages. Background Art

[0002] In tobacco processing, tobacco leaves need to be packed into bundles and sent to the tobacco factory after being roasted. The tobacco factory needs to divide the bundles into small pieces to take advantage of subsequent processes such as vacuum rehydration of the tobacco blocks, and finally make finished tobacco products.

[0003] The bundled cigarette bales generally delivered to the cigarette factory have standard length, width and height dimensions, which are generally 1115×690×725 (mm) respectively. The standard weight of the cigarette bales is about 200kg. They are made by compressing re-roasted tobacco strips through a hydraulic press.

[0004] Therefore, the density of cigarette packs is relatively large. Generally, after passing through a slitting machine, a cigarette pack is cut into 4-5 pieces. Even after being cut into small pieces by a slitting machine, the weight of each piece will be about 40-50kg.

[0005] When the cigarette packs divided into small pieces are sent to the next-level conveyor through the conveyor, due to the design of the production line, there is a certain height difference between the upstream conveyor and the downstream conveyor. When the upstream conveyor is higher than the downstream conveyor, if the cigarette packs on the upstream conveyor fall onto the downstream conveyor by free fall, the fallen cigarette packs will cause serious impact on the downstream conveyor and cause damage to the downstream conveyor.

[0047] This application makes improvements and innovations and proposes the following embodiments.

[0048] In some embodiments, please refer to Figures 1 to 7 , a slitting cigarette pack conveying device is provided, including:

[0049] An upstream conveyor 1, wherein the upstream conveyor 1 is provided with a slitting machine 11 for slitting cigarette packs;

[0050] A downstream conveyor 2, wherein the downstream conveyor 2 is located below the upstream conveyor 1;

[0051] A connecting frame 3, wherein the connecting frame 3 is fixedly connected to the discharge end of the upstream conveyor 1; the connecting frame 3 is mounted on the downstream conveyor 2;

[0052] The deceleration mechanism 4 has a bearing portion 41 that can convey the cigarette packs on the upstream conveyor 1 to the downstream conveyor 2 . The deceleration mechanism 4 also has a reducer 42 that is transmission-connected to the bearing portion 41 . The reducer 42 is mounted on the connecting frame 3 .

[0053] The slitting machine 11 is a slitting machine 11 on the market.

[0054] When a large cigarette pack passes through the upstream conveyor 1, it is cut into small cigarette packs by the slitting machine 11 and enters the bearing part 41 of the speed reduction mechanism 4. The cigarette pack moves downward along the bearing part 41 to the downstream conveyor 2. Due to the speed reducer 42, the cigarette pack on the bearing part 41 slowly moves downward to the downstream conveyor 2. The soft landing of the cigarette pack on the downstream conveyor 2 is achieved, and the service life of the downstream conveyor 2 is increased.

[0055] In one embodiment, the reducer 42 is provided with a brake pad 421 for decelerating the bearing portion 41, and the brake pad 421 is driven by a pusher 422 to move closer to or away from the bearing portion 41. The brake pad 421 can improve the deceleration effect on the bearing portion 41.

[0056] Specifically, the pushing member 422 is a rod with threads. The pushing member 422 is threadedly matched with the reducer 42 . The pushing member 422 can push the brake pad 421 to abut against the bearing portion 41 , thereby increasing the resistance to the movement of the bearing portion 41 .

[0057] In one embodiment, the bearing portion 41 includes a conveyor belt 411, and the brake pad 421 can be in contact with the roller 412 of the conveyor belt 411. The cigarette pack is located on the conveyor belt 411 and moves to the downstream conveyor 2 along the conveying direction of the conveyor belt. The brake pad 421 abuts against the roller 412 to reduce the moving speed of the conveyor belt. This reduces the speed at which the cigarette pack moves downward, and enables the cigarette pack to land softly on the downstream conveyor 2. This reduces the impact on the downstream conveyor 2 and increases the service life of the downstream conveyor 2.

[0058] In one solution, the bearing part 41 further includes a support plate 413; the support plate 413 is located within the area enclosed by the conveyor belt 411, the support plate 413 is rotatably connected to the roller 412, and the support plate 413 is slidably limited to the connecting frame 3. The support plate 413 can provide support for the cigarette packs, ensuring that the cigarette packs can move on the conveyor belt 411 to the downstream conveyor 2.

[0059] Specifically, the number of rollers 412 is two, located at both ends of the support plate 413; the support plate 413 has a slider 414, and the connecting frame 3 is provided with an arc-shaped groove 31 for the slider 414 to slide and engage. A spring 32 is provided in the arc-shaped groove 31. One end of the spring 32 abuts against the slider 414 and the other end abuts against one end of the arc-shaped groove 31. By providing the slider 414, the arc-shaped groove 31 and the spring 32, when there is no cigarette pack on the conveyor belt 411, the spring 32 pushes the support plate 413 to be perpendicular to the conveying direction of the upstream conveyor 1 to receive the cigarette packs from the upstream conveyor 1, that is, to fit against the side of the cigarette pack. As the cigarette pack moves, the cigarette pack pushes the conveyor belt 411 to rotate onto the downstream conveyor belt 411, and the cigarette pack then moves along the conveyor belt 411 to the upstream conveyor 1. This avoids the cigarette pack rotating at the discharge port of the upstream conveyor 1 and falling onto the conveyor belt 411, causing damage to the conveyor belt 411.

[0060] In one solution, the bearing part 41 includes a conveyor chain 416 having a bearing frame 415. The conveyor chain 416 is drivingly connected to a runner 418, and the runner 418 is rotatably connected to the connecting frame 3; the brake pad 421 can be fitted and abutted against the runner 418; the reducer 42 is fixedly connected to the connecting frame 3. The cigarette packs enter the bearing frame 415 from the upstream conveyor 1 and move downward along the bearing frame 415 to the downstream conveyor 2. Since the brake pad 421 is fitted and abutted against the runner 418, the falling speed of the bearing frame 415 is reduced, realizing the soft landing of the cigarette packs on the downstream conveyor 2.

[0061] Specifically, the number of runners 418 is two, and the two runners 418 are spaced apart in the vertical direction. The conveyor chain 416 is meshed and driven with the runner 418. An arc-shaped sliding surface 5 for the cigarette packs to slide into the downstream conveyor 2 is provided at the feeding end position of the downstream conveyor 2. The arc-shaped sliding surface 5 is spaced apart from the bearing frame 415. When the cigarette packs in the bearing frame 415 move to the lower part of the upstream conveyor 1, the upper ends of the cigarette packs slide along the arc-shaped sliding surface 5 to coincide with the conveying direction of the downstream conveyor 2, avoiding the situation where the cigarette packs directly fall from the bearing frame 415 onto the downstream conveyor 2.

[0062] In one embodiment, a guide plate 6 is provided below the deceleration mechanism 4; the guide plate 6 has two opposite ends, wherein one end edge of the guide plate 6 is connected to the discharge end of the upstream conveyor 1, and the other end edge of the guide plate 6 is located above the downstream conveyor 2. The guide plate 6 can assist the cigarette packs to move along the guide plate 6 to the downstream conveyor 2.

[0063] Specifically, the guide plate 6 is in an arc shape and has a certain elastic deformation. The elastic deformation can buffer the cigarette packs and reduce the impact of the cigarette packs on the downstream conveyor 2.

[0064] In one solution, a buffer 61 is provided below the guide plate 6, the lower end of the buffer 61 is hinged to the connecting frame 3, and the upper end of the buffer 61 is fixedly connected to the lower end surface of the guide plate 6. The buffer 61 can eliminate the kinetic energy of the cigarette pack and reduce the impact on the downstream conveyor 2.

[0065] Specifically, the buffer 61 is a shock absorber used in the suspension of an automobile. The shock absorber used in an automobile can be convenient or material, and the market is widely divided.

[0066] In one embodiment, one end of the rotating roller 21 of the downstream conveyor 2 is fixedly connected to a round table 22; the roller 412 is connected to the round table 22 through a belt 23, and the round table 22 is connected to a driving motor 24. The kinetic energy of the cigarette pack can be fully utilized through the drive of the belt 23, and the kinetic energy is transmitted to the downstream conveyor 2 to drive the rotation of the downstream conveyor 2.

[0067] Specifically, the driving motor 24 is fixedly connected to a support frame of the downstream conveyor 2 .

[0068] In one embodiment, the driving motor 24 is fixedly connected to a cylinder 7, and the output end of the cylinder 7 is connected to a pull plate 71 for pulling the belt 23. The cylinder 7 is used to pull the belt 23 to move on the round table 22 to adjust the tension of the connection between the belt 23 and the round table 22, thereby realizing the driving and separation of the round table 22 by the belt 23. When no cigarette pack moves down to the downstream conveyor belt, the connection between the belt 23 and the round table 22 can be disconnected.

[0069] Specifically, a rotating rod 72 is provided on the pulling plate 71 , and the rotating rod 72 abuts against the belt 23 to reduce the wear of the belt 23 .

[0070] In one solution, it further includes a processor 8; a laser sensor 9 is provided on the connecting frame 3; the laser sensor 9, the cylinder 7, the slitter 11, and the drive motor 24 are all electrically connected to the processor 8. When the laser sensor 9 detects that there is a cigarette pack on the carrying part 41, the processor 8 controls the cylinder 7 to contract and move, and the pull plate 71 pulls the belt 23 to move, improving the tension degree of the connection between the belt 23 and the frustum 22. The degree of automation is improved.

[0071] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, replacements, and variations to the above embodiments within the scope of the present invention.
