[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] In related technologies, cigarette pack sorting equipment is used in cigarette production lines to flexibly sort and transport formed cigarette packs. It uses conveyor belts to transport and divert the cigarette packs, ensuring the continuity and efficiency of subsequent packaging and boxing processes. It is one of the key pieces of equipment in cigarette production to guarantee the processing quality and production efficiency of cigarette packs. Currently, cigarette pack sorting equipment experiences issues such as cigarette pack slippage or loosening between the packs and the conveyor belt, leading to pack jamming or deviation in the transport posture, thus affecting the transport efficiency.

[0026] Please refer to Figure 1 As shown, an embodiment of this application provides a cigarette pack repackaging device 100, which includes two transmission components 110.

[0027] Specifically, in combination Figure 1 and Figure 2 As shown, two transmission components 110 are arranged opposite to each other and a gap 140 is formed between the two transmission components 110 for moving the cigarette pack. Each transmission component 110 includes a first transmission belt 111, a plurality of flexible connectors 112 and an adjusting member 113. Each flexible connector 112 abuts against the side of the first transmission belt 111 away from the cigarette pack, and each flexible connector 112 moves relative to the first transmission belt 111 along a direction perpendicular to the transmission direction to adjust the clamping force on the cigarette pack.

[0028] In this embodiment, the adjusting member 113 is installed on the flexible connector 112, and the end of the adjusting member 113 away from the flexible connector 112 abuts against the first conveyor belt 111. The adjusting member 113 can extend or retract perpendicular to the transmission direction to adjust the tension of the first conveyor belt 111. The first conveyor belts 111 of the two transmission components 110 are synchronously driven along the transmission direction. Correspondingly, a gap 140 is formed between the two transmission components 110 so that the cigarette pack can be transmitted through the gap 140. The flexible connector 112 of the two transmission components 110 can extend perpendicular to the transmission direction after being squeezed by the cigarette pack. The relative movement adjusts the clamping force on the cigarette pack, allowing it to pass smoothly through the gap 140 for transmission. The relative movement of the flexible connector 112 avoids hindering the transmission of the cigarette pack. The adjusting member 113 can adjust the tension of the first conveyor belt 111 by extending or retracting, achieving the purpose of fine-tuning the tension of the first conveyor belt 111. This reduces the possibility of slippage or separation between the cigarette pack and the first conveyor belt 111, prevents the cigarette pack from getting stuck or shifting its transmission posture, reduces the impact on the elasticity of the first conveyor belt 111 and the spacing accuracy of the gap 140, thereby improving the transmission effect of the first conveyor belt 111.

[0029] It is easy to understand that the first conveyor belts 111 of the two opposing conveyor components 110 have opposite conveying directions so as to drive the cigarette packs to be conveyed synchronously in the gap 140. After the cigarette pack dispensing device 100 of this application has been used for a long time, the adjusting member 113 can finely adjust the tension of the first conveyor belt 111, so that the flexible connector 112 can easily clamp the cigarette packs and convey them, reducing the dependence on the elasticity of the conveyor belt itself and the accuracy of the initial gap 140.

[0030] refer to Figure 2 and Figure 6 As shown, the cigarette pack dispensing device 100 has a first direction X and a second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other. For example, the first direction X, taking the transmission direction of the cigarette pack dispensing device 100 as an example, is the length direction of the cigarette pack dispensing device 100; the second direction Y, taking it perpendicular to the transmission direction of the cigarette pack dispensing device 100 as an example, is the height direction of the cigarette pack dispensing device 100. It is understood that the above definitions are only for the convenience of understanding the relative positional relationships of the various parts in the cigarette pack dispensing device 100 and should not be construed as a limitation of this application.

[0031] Optionally, refer to Figure 2As shown, the flexible connector 112 includes a fixed block 1121, an elastic sheet 1122, and a tension roller 1123. One end of the elastic sheet 1122 is connected to the fixed block 1121, and the other end of the elastic sheet 1122 away from the fixed block 1121 abuts against the tension roller 1123. The tension roller 1123 is used to abut against the first conveyor belt 111. The fixed block 1121 is used to support and connect the elastic sheet 1122. When the cigarette pack abuts against the first conveyor belt 111 and presses the tension roller 1123, the tension roller 1123, in conjunction with the elastic sheet 1122, can adjust the clamping force on the cigarette pack, so that the tension roller 1123 can clamp the cigarette pack and achieve the purpose of flexibly clamping the cigarette pack.

[0032] Optionally, refer to Figure 2 and Figure 3 As shown, the tension roller 1123 is provided with a mounting groove 1124, and the adjusting member 113 is provided in the mounting groove 1124. The adjusting member 113 can extend out of the mounting groove 1124 toward the opening of the mounting groove 1124 to tension the first conveyor belt 111. The adjusting member 113 can be used to adjust the tension of the first conveyor belt 111. When the cigarette pack squeezes the first conveyor belt 111 and the first conveyor belt 111 squeezes the tension roller 1123, the adjusting member 113 can press against the first conveyor belt 111 and be used to adjust the first conveyor belt 111. The adjusting member 113 can finely adjust the tension of the first conveyor belt 111 in real time to reduce slippage caused by belt slack and ensure continuous and smooth transmission of the cigarette pack.

[0033] In summary, a gap 140 is formed between the two transmission components 110 of the cigarette pack dispensing device 100 to facilitate the transmission of cigarette packs through the gap 140. The flexible connectors 112 of the two transmission components 110 can move relative to each other in a direction perpendicular to the transmission direction after being squeezed by the cigarette packs to adjust the clamping force on the cigarette packs, so that the cigarette packs can be clamped and transmitted through the gap 140 more smoothly. The relative movement of the flexible connectors 112 can avoid hindering the transmission of cigarette packs. The adjusting component 113 can adjust the tension of the first transmission belt 111 by extending or retracting, so as to achieve the purpose of fine-tuning the tension of the first transmission belt 111, reducing the slippage or separation of the contact position between the cigarette packs and the first transmission belt 111, preventing the cigarette packs from getting stuck or deviating in the transmission posture, thereby improving the transmission effect of the first transmission belt 111.

[0034] refer to Figure 1 As shown, an embodiment of this application provides another cigarette pack repackaging device 100, which includes two transmission components 110.

[0035] Specifically, in combination Figure 1 and Figure 2As shown, two transmission components 110 are arranged opposite to each other and a gap 140 is formed between the two transmission components 110 for moving the cigarette pack. Each transmission component 110 includes a first transmission belt 111, a plurality of flexible connectors 112 and an adjusting member 113. Each flexible connector 112 abuts against the side of the first transmission belt 111 away from the cigarette pack, and each flexible connector 112 moves relative to the first transmission belt 111 along a direction perpendicular to the transmission direction to adjust the clamping force on the cigarette pack. The adjusting member 113 is installed on the flexible connector 112, and the end of the adjusting member 113 away from the flexible connector 112 abuts against the first conveyor belt 111. The adjusting member 113 can extend or retract perpendicular to the transmission direction to adjust the tension of the first conveyor belt 111. The first conveyor belts 111 of the two transmission assemblies 110 are synchronously driven along the transmission direction. Correspondingly, a gap 140 is formed between the two transmission assemblies 110 so that the cigarette pack can be transmitted through the gap 140. The flexible connector 112 of the two transmission assemblies 110 can move relative to each other perpendicular to the transmission direction after being squeezed by the cigarette pack. The clamping force on the cigarette pack is adjusted to allow the cigarette pack to pass through the gap 140 smoothly. The relative movement of the flexible connector 112 can avoid hindering the transmission of the cigarette pack. The adjusting member 113 can adjust the tension of the first conveyor belt 111 by extending or retracting, so as to achieve the purpose of fine adjustment of the tension of the first conveyor belt 111, reduce the slippage or separation of the cigarette pack at the contact position with the first conveyor belt 111, prevent the cigarette pack from getting stuck or the transmission posture of the cigarette pack from deviating, reduce the impact on the elasticity of the first conveyor belt 111 and the spacing accuracy of the gap 140, and thus improve the transmission effect of the first conveyor belt 111.

[0036] For example, the cigarette pack dispensing device 100 also includes two housings 150, two transmission components 110 are respectively disposed in the two housings 150, the two housings 150 are disposed opposite each other and form a gap 140, and the first transmission belts 111 of the two transmission components 110 are exposed in the housings 150 to facilitate carrying and transmitting the cigarette packs.

[0037] In one embodiment, alternatively, referencing Figure 2As shown, the flexible connector 112 includes a fixed block 1121, an elastic sheet 1122, and a tension roller 1123. One end of the elastic sheet 1122 is connected to the fixed block 1121, and the other end of the elastic sheet 1122 away from the fixed block 1121 abuts against the tension roller 1123. The tension roller 1123 is used to abut against the first conveyor belt 111. The fixed block 1121 is used to support and connect the elastic sheet 1122. When the cigarette pack abuts against the first conveyor belt 111 and presses the tension roller 1123, the tension roller 1123, in conjunction with the elastic sheet 1122, can adjust the clamping force on the cigarette pack, so that the tension roller 1123 can clamp the cigarette pack and achieve the purpose of flexibly clamping the cigarette pack. In addition, when the cigarette pack leaves the corresponding position of the tension roller 1123, the elastic sheet 1122 can generate a reverse elastic force after being pressed, and the elastic sheet 1122 drives the tension roller 1123 to reset.

[0038] In one embodiment, alternatively, such as Figure 2 As shown, multiple flexible connectors 112 are spaced apart along the transmission direction, and multiple adjusting members 113 are provided, each of which corresponds to one flexible connector 112. The multiple flexible connectors 112 are spaced apart along the transmission direction of the cigarette pack, so that the cigarette pack is uniformly clamped throughout the transmission process, avoiding local stress concentration. The multiple flexible connectors 112 maintain flexible clamping of the cigarette pack throughout the transmission process. The flexible connectors 112 allow the first conveyor belt 111 to self-adapt to displacement within a certain range, which facilitates the transfer of the cigarette pack and helps the cigarette pack maintain a relatively accurate position and posture during the transmission process. This reduces the requirements for the accuracy of the initial gap 140 and the elasticity of the conveyor belt itself, and improves the adaptability of the cigarette pack dispensing device 100.

[0039] Optionally, refer to Figure 2 and Figure 3 As shown, the tension roller 1123 is provided with a mounting groove 1124, and the adjusting member 113 is provided in the mounting groove 1124. The adjusting member 113 can extend out of the mounting groove 1124 toward the opening of the mounting groove 1124 to tension the first conveyor belt 111. The adjusting member 113 can be used to adjust the tension of the first conveyor belt 111. When the cigarette pack squeezes the first conveyor belt 111 and the first conveyor belt 111 squeezes the tension roller 1123, the adjusting member 113 can press against the first conveyor belt 111 and be used to adjust the first conveyor belt 111. The adjusting member 113 can finely adjust the tension of the first conveyor belt 111 in real time to reduce slippage caused by belt slack and ensure continuous and smooth transmission of the cigarette pack.

[0040] For example, such as Figure 3As shown, the adjusting member 113 includes a telescopic rod 1131, a connecting shaft 1132, and an adjusting rod 1133. The telescopic rod 1131 is connected to the connecting shaft 1132, and the adjusting rod 1133 is rotatably connected to the connecting shaft 1132. When the telescopic rod 1131 extends or retracts, it can drive the connecting shaft 1132 to move relative to it, so that the adjusting rod 1133 extends out of the mounting groove 1124, or the adjusting rod 1133 is received in the mounting groove 1124. The mounting groove 1124 can be used to store the adjusting rod 1133 and can drive the telescopic rod 1131 to move, so that the telescopic rod 1131 drives the adjusting rod 1133 to extend or retract through the connecting shaft 1132, so that the adjusting rod 1133 extends out of the mounting groove 1124 and abuts against the first conveyor belt 111.

[0041] In the long-term continuous operation of existing cigarette packing equipment, the conveyor belt is always in a state of dynamic tension and friction. With the accumulation of operating time, the elastic sheet 1122 is prone to aging phenomena such as material fatigue and elasticity decay, which leads to a decrease in its clamping performance on the cigarette packs. This may not only cause problems such as cigarette pack conveying posture deviation and packing disorder, but also increase the failure rate and replacement frequency of the conveyor belt, affecting production continuity and increasing equipment operation and maintenance costs.

[0042] In one embodiment, optionally, combining Figure 2 and Figure 4 As shown, the cigarette pack dispensing device 100 also includes a movable component 120, which is installed on the flexible connector 112. The movable component 120 can abut against the side of the elastic sheet 1122 away from the tension roller 1123 to drive the elastic sheet 1122 to switch between a reset state and a compressed state. The movable component 120 can drive the elastic sheet 1122 to move when it is deformed. The elastic sheet 1122 can still switch between the reset state and the compressed state to compensate for the fatigue deformation of the elastic sheet 1122. This allows the elastic sheet 1122 to drive the tension roller 1123 to move and clamp the cigarette pack, always maintaining a certain elasticity of the elastic sheet 1122. This reduces the impact of deformation or damage to the elastic sheet 1122 on the cigarette pack transmission, reduces the frequency of replacement of the elastic sheet 1122, ensures the reliability of the structure, and thus improves the performance of the cigarette pack dispensing device 100.

[0043] Optionally, such as Figure 4 and Figure 5As shown, the movable component 120 is provided with a first bearing cavity 121, a second bearing cavity 122, a liquid regulating component 123, and a movable rod 124. The first bearing cavity 121 and the second bearing cavity 122 are connected to form a liquid channel. The liquid regulating component 123 is connected to the first bearing cavity 121 through a regulating valve. The elastic plate 1122 is used to abut one end of the movable rod 124. The end of the movable rod 124 away from the elastic plate 1122 is inserted into the first bearing cavity 121. When the movable rod 124 moves relative to the first bearing cavity 121, it can change the volume of the first bearing cavity 121, so that the liquid flows between the first bearing cavity 121 and the second bearing cavity 122, thus regulating the liquid flow. Component 123 can be used to regulate the total amount of liquid in the liquid channel via a regulating valve. When the movable component 120 is in use, the liquid channel has sufficient liquid. The movable rod 124 compresses the first bearing cavity 121, allowing liquid to enter the second bearing cavity 122 from the first bearing cavity 121. This maintains hydraulic balance between the first bearing cavity 121 and the second bearing cavity 122, so that the relative movement of the movable rod 124 can be driven by the liquid changes in the first bearing cavity 121 and the second bearing cavity 122. This causes the movable rod 124 to push the elastic plate 1122 to move, keeping the elastic plate 1122 in the reset and compressed states even when it is deformed or damaged, thus improving the stability of the cigarette pack's transmission posture.

[0044] For example, refer to Figure 5As shown, the movable component 120 further includes a carrier box 125, a first elastic element 127, a push plate 126, and a second elastic element 128. The first elastic element 127 is disposed in the first carrier cavity 121 and is connected to the movable rod 124. The first elastic element 127 provides a certain elastic restoring effect to the movable rod 124. The push plate 126 is disposed in the carrier box 125 and isolating it into a second carrier cavity 122 and a third carrier cavity 129. The second elastic element 128 is disposed in the third carrier cavity 129 and is connected to the push plate 126. The second elastic element 128 provides a certain elastic restoring effect to the push plate 126. The push plate 126 can change the volume of the second carrier cavity 122 and the third carrier cavity 129. Correspondingly, when the cigarette pack stops squeezing the conveyor belt, the elastic sheet 11... 22 Reset, the elastic sheet 1122 stops driving the tension roller 1123, the second elastic element 128 is compressed and drives the push plate 126 to move, so that the push plate 126 compresses the volume of the second bearing cavity 122, the liquid flows from the second bearing cavity 122 to the first bearing cavity 121, so that the volume of the first bearing cavity 121 increases to push the movable rod 124 to move, so that the movable rod 124 drives the elastic sheet 1122 back to its original position, which plays a certain auxiliary role in preventing the elastic sheet 1122 from being deformed and damaged and unable to return to its original position. The push plate 126 squeezes the liquid in the bearing box 125, so that the liquid in the bearing box 125 flows into the first bearing cavity 121. The tension roller 1123 has a certain elastic movement space, so that the tension roller 1123 keeps in contact with the conveyor belt. The conveyor belt can always have a better clamping force on the cigarette pack, thereby improving the product service life of the cigarette pack dispensing device 100.

[0045] In this process, after the cigarette pack is squeezed by the tension roller 1123, the elastic sheet 1122 is compressed, the movable rod 124 compresses the first bearing cavity 121, and the liquid flows into the second bearing cavity 122. After the cigarette pack leaves the corresponding tension roller 1123, the second elastic element 128 pushes the push plate 126 to make the liquid flow back to the first bearing cavity 121, lifts the movable rod 124, and assists the elastic sheet 1122 to reset. This improves the stability and reliability of the cigarette pack transmission, reduces maintenance requirements, and is suitable for high-speed and continuous tobacco production lines.

[0046] In one embodiment, alternatively, referencing Figure 2 and Figure 6As shown, the cigarette packing device 100 further includes a drive assembly 130, which includes a first drive wheel 131, a second drive wheel 132, a second transmission belt 133, and a drive member 134.
