[0026] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] Example:
[0030] refer to Figure 1 and Figure 2 As shown, a double-layer cigarette pack conveying device includes a turret 4, which is circular. Multiple cigarette pack molds 5 are evenly arranged on the outer edge of the turret 4. Each pair of cigarette pack molds 5 can hold or place cigarette packs. A driven shaft 1 is located above the turret 4. One end of the driven shaft 1 is fixedly connected to the upper end of a vertical connecting rod 2. The ends of the driven shaft 1 and the vertical connecting rod 2 are connected end-to-end to an external main transmission component, used to drive the driven shaft 1 to complete reciprocating linear motion. The ends of the vertical connecting rod 2 and the driven shaft 1 are connected end-to-end to a push rod 3. The centerline of the cigarette pack mold 5 and the centerline of the push rod 3 are on the same horizontal plane. The driven shaft 1 drives the push rod 3 to perform reciprocating linear motion through the vertical connecting rod 2. The push rod 3 pushes the cigarette packs located between the pairs of cigarette pack molds 5. The fact that the centerline of the cigarette pack mold 5 and the centerline of the push rod 3 are on the same horizontal plane ensures that the push rod 3 can accurately act on each cigarette pack during each operation, thereby achieving efficient and consistent operation.
[0031] Among them, a push plate 32 is installed on the end of the connection between the push rod 3 and the vertical connecting rod 2. The push plate 32 is designed in a cross shape. The cross-shaped push plate 32 can increase the contact area between the push rod and the cigarette pack or mold box, ensuring that the push force can be distributed more evenly and improving the efficiency of push force transmission. The larger contact surface reduces the pressure per unit area and reduces the risk of damage to the surface of the cigarette pack. The cross-shaped push plate 32 can better adapt to cigarette packs of different sizes and shapes, increasing the application flexibility of the equipment.
[0032] Among them, the push plate 32 is made of flexible material. The flexible material can effectively buffer the contact force between the push plate 32 and the cigarette pack, preventing indentations, scratches or other physical damage to the surface of the cigarette pack during the pushing process. Flexible materials usually have good wear resistance, reducing wear during long-term use and extending the service life of the push plate 32.
[0033] The cigarette pack mold box 5 has slots 51 on both sides. The slots 51 can facilitate the placement of cigarette packs, ensure the stability of cigarette packs during transportation, prevent cigarette packs from falling off, and facilitate the movement of cigarette packs to the next process.
[0034] It should be noted that the diameter of the turret 4 and the width, size, and spacing of the cigarette pack mold 5 should be designed according to the different specifications and sizes of cigarette packs so that they can be applied to more scenarios.
[0035] refer to Figures 2-4 As shown, a connecting rod 21 is provided on the end opposite to the connection between the vertical connecting rod 2 and the drive driven shaft 1. The connecting rod 21 is provided with a groove 211 that is slidably connected to the push rod 3. Both ends of the groove 211 pass through the connecting rod 21. A stop 6 is provided on one end of the groove 211. A spring piece 7 is provided on the end of the stop 6 located inside the groove 211. One end of the push rod 3 passes through the groove 211 from the other end. The end of the push rod 3 located inside the groove 211 abuts against the end of the connection between the spring piece 7 and the stop 6. The spring piece 7 gives the push rod 3 a certain self-adjustment ability when it encounters resistance. When the pressure on the push rod 3 is greater than usual, the spring piece 7 can be temporarily compressed to protect the cigarette pack and prevent indentations from appearing on the cigarette pack.
[0036] refer to Figure 4 and Figure 5 As shown, the overload detection mechanism includes a spring 81, an overload button 82, and a steel ball 83. The resist 6 is located within the slide groove 211, and one end of the resist 6 is also provided with a groove 61. The groove 61 is located below the spring piece 7, and one end of the groove 61 passes through the resist 6 within the slide groove 211. A limiting edge 611 is provided at the opening of the groove 61. The groove 61 contains the spring 81, the overload button 82, and the steel ball 83. The overload button 82 is located at the bottom of the groove 61. One end of the push rod 3 abuts against the groove 61, and the other end abuts against the steel ball 83. The steel ball 83 abuts against the overload button 82. When the push rod 3 encounters abnormal resistance or overload, the spring 7 will apply pressure to the steel ball 83. The steel ball 83 will compress the spring 81 under pressure and trigger the overload button 82, causing the equipment to stop and wait for the operator to handle it. Once the overload situation is relieved, the spring 81 will return to its original state and push the steel ball 83 back to the initial position. The system can resume normal operation without manual intervention.
[0037] The limiting edge 611 at the opening of the groove 61 can prevent the steel ball 83 from being ejected.
[0038] refer to Figure 6As shown, slide rails 212 are provided on both sides of the slide groove 211. The push rod 3 is provided with a limiting block 31 that is slidably connected to the slide rail 212 at one end of the slide groove 211. The length of the slide rail 212 is the height of the spring piece 7 plus the height of the limiting block 31. One end of the slide rail 212 is flush with the end of the stop 6 located in the slide groove 211, which enables the push rod 3 to make precise linear movement on a predetermined path. When the push rod 3 is not overloaded, the limiting block 31 on the push rod 3 is pressed by the spring piece 7 at the end of the slide rail 212, which prevents the push rod 3 from not completely following the movement of the driven shaft 1.
[0039] The operation process of this utility model is as follows:
[0040] S1. The cigarette packs produced in the previous process are smoothly conveyed into the middle of the two cigarette pack mold boxes 5. The rotating turret 4 drives the cigarette packs in the middle of the two cigarette pack mold boxes 5 to rotate until they are transported to the push plate 32.
[0041] S2. When the cigarette pack reaches the cigarette pushing station, the external main transmission component drives the driven shaft 1 to push it outward. The vertical connecting rod 2 drives the push rod 3 and the push plate 32 to push the cigarette pack out from between the two cigarette pack mold boxes 5 and send the cigarette pack to the next process.
[0042] S3. Repeat the appeal steps S1-S2 to complete the cigarette pack delivery;
[0043] S4. When performing the above steps, if the pushing force of the push plate 32 reaches a certain threshold, that is, the cigarette pack may be indented, the spring 7 can be temporarily compressed to protect the cigarette pack and avoid indentation on the cigarette pack.
[0044] S5. In S4, if the pushing force of the push plate 32 reaches a certain threshold, the spring 7 will apply pressure to the steel ball 83. The steel ball 83 will compress the spring 81 under pressure and trigger the overload button 82, causing the equipment to stop and wait for the operator to handle it.
[0045] S6. The device continues to work, executing steps S1-S5 to continuously complete the optimized conveying of the tobacco packages.
[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
