Description

Technical Field

[0001] This utility model relates to a packaging device, and more particularly to a multifunctional packaging device for tobacco logistics, belonging to the field of tobacco packaging technology. Background Technology

[0002] After tobacco is processed into the shape commonly used for smoking, the processed cigarettes need to be packaged into small boxes, and then a certain number of boxes are packed into a carton. After being packaged into cartons, the cartons are transported in two ways. One method is to pack the cartons directly into cigarette boxes and transport the boxes directly; the other method is to stack the cartons together and wrap them with a protective film, which facilitates later transportation and also provides sealing, moisture protection, and pollution prevention. Currently, fully automated carton stacking and wrapping devices are widely used, which can complete a series of processes including stacking, wrapping, and unloading of the cartons.

[0003] Existing tobacco pack wrapping and sealing equipment typically includes a tobacco pushing and feeding mechanism. However, in practical use, it has been found that one type of existing tobacco pushing and feeding mechanism, such as... Figure 9-10 As shown, it includes a smoke-pushing plate 25, a lifting smoke-receiving plate 26, a transfer chain conveyor, and a lifting smoke-blocking plate 27. In use, the stack of cigarettes to be wrapped enters the lifting smoke-receiving plate. Then, the smoke-pushing plate pushes the stack of cigarettes on the lifting smoke-receiving plate from one side of the transfer chain conveyor onto the transfer chain conveyor. During this process, the lifting smoke-blocking plate limits the stack of cigarettes on the other side of the transfer chain conveyor. A single-entry structure can be formed by setting the smoke-pushing plate only on one side of the transfer chain conveyor, or a double-entry structure can be formed by setting smoke-pushing plates on opposite sides of the transfer chain conveyor. Because the smoke-pushing plate is a single plate, the lifting smoke-receiving plate can only be lowered to its lowest position after each smoke reception to meet the conditions for pushing the stack of cigarettes onto the transfer chain conveyor. When smoke-pushing plates are set on both sides of the transfer chain conveyor, and the stacks of cigarettes at both inlets are originally from the same household, they cannot be pushed together for wrapping. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a multifunctional packaging device for tobacco logistics.

[0005] The technical solution adopted in this utility model is as follows: a multifunctional packing device for tobacco logistics is designed, which includes a push fork, a lifting fork, and a transfer chain conveyor. The push fork and the lifting fork are arranged on one side of the transfer chain conveyor. The push fork can perform horizontal telescopic movement relative to the transfer chain conveyor, and the lifting fork can perform lifting movement relative to the transfer chain conveyor. The forks of the push fork and the lifting fork are staggered. After the tobacco stack enters the lifting fork, the push fork pushes the tobacco stack on the lifting fork onto the transfer chain conveyor.

[0006] With the above structure, the cigarette stack on the lifting fork can be pushed onto the transfer chain conveyor by the push fork at any height. It can also be used for combined packing. In combined packing, a cigarette stack A of a certain height is fed into the lifting fork. The lifting fork is lowered to its lowest position, and the push fork pushes the cigarette stack A onto the transfer chain conveyor. Then, the lifting fork receives another cigarette stack B and raises it until the height of the other cigarette stack B on the transfer chain conveyor is higher than the height of the cigarette stack A on the transfer chain conveyor. Finally, the push fork pushes the cigarette stack B on the lifting fork onto the transfer chain conveyor to combine it with the cigarette stack A into a single pack.

[0007] Furthermore, the transfer chain conveyor is equipped with push forks and lifting forks on both the left and right sides, forming a dual-inlet structure. Similarly, this structure allows the push forks to be used to push the tobacco stacks on the lifting forks onto the transfer chain conveyor at any height. It can also be used for packing. In this case, assuming the lifting fork on the left side of the transfer chain conveyor receives tobacco stack A and the lifting fork on the right side receives tobacco stack B, the lifting fork on the left side of the conveyor conveyor lowers to its lowest position, and the lifting fork on the right side rises until tobacco stack B is higher than tobacco stack A. Then, the push forks on both sides of the transfer chain conveyor push tobacco stacks A and B onto the conveyor conveyor for packing. During the process of pushing the tobacco stacks onto the transfer chain conveyor, the lifting forks on opposite sides can act as smoke deflectors, reducing tobacco loss.

[0008] Furthermore, the cigarette pusher includes a cigarette pusher plate and an integrated base. Multiple cigarette pusher plates are arranged in an array on the integrated base. The integrated base is made of rectangular tube, and the cigarette pusher plate is made of hollow plate. The overall structure is relatively light, ensuring a large contact area and making the cigarette stack bear force evenly. Furthermore, the integrated base has a socket, and the lower end of the smoke pusher plate has a slot. The lower end of the smoke pusher plate is inserted into the integrated base on one side of the socket through the slot. The socket penetrates the integrated base, and the lower end of the smoke pusher plate is flush with the lower surface of the integrated base. The socket and slot cooperate to achieve quick assembly and disassembly, facilitating the replacement of worn smoke pusher plates. The through-hole enhances the connection rigidity between the smoke pusher plate and the integrated base, preventing displacement and offset.

[0009] Furthermore, the lifting cigarette receiving fork includes a rectangular cigarette receiving frame and an integrated rod. Multiple rectangular cigarette receiving frames are arranged in an array to form a rectangular frame, the upper surface of which is used to receive the cigarette stack. All rectangular cigarette receiving frames are connected by the integrated rod. The integrated base is disposed within the rectangular frame. The cigarette pushing plate is staggered with the rectangular cigarette receiving frame to avoid mechanical interference. The lower end of the cigarette pushing plate is provided with a clearance notch to allow the cigarette pushing fork to completely push out the cigarette stack, while ensuring that the cigarette pushing fork does not interfere with the transfer chain conveyor, thus ensuring that the cigarette stack is completely transferred to the transfer chain conveyor.

[0010] Furthermore, the rectangular smoke receiving frame includes a C-shaped frame and a partition beam disposed at the opening of the C-shaped frame. Both the C-shaped frame and the partition beam are made of rectangular tubing, taking into account both lightweight and load-bearing requirements.

[0011] Furthermore, the integrated rod is a screw rod, and a connecting hole is provided at the connection between the rectangular smoke receiving frame and the integrated rod. A nut sleeve is provided in the connecting hole, and the nut sleeve is threadedly connected to the integrated rod, which ensures a stable and reliable connection and facilitates replacement and maintenance.

[0012] Furthermore, the integrated rod includes a first integrated rod, a second integrated rod, and a third integrated rod respectively disposed at three corners of the lifting and receiving cigarette fork. The first integrated rod is also provided with a spacer, and a spacer is provided between each pair of rectangular cigarette receiving frames to ensure stable spacing and prevent interference with the pushing cigarette fork.

[0013] Furthermore, this design also includes a frame, a traverse motor, and a transmission belt. The traverse motor and transmission belt are mounted on the frame. The output end of the traverse motor is connected to the transmission belt and can drive it to rotate. The push fork is provided with a traverse connecting seat, which is connected to the transmission belt. A boss is provided under the push fork, and a guide rail is provided on the frame. A slider is provided on the guide rail, and the boss is connected to the slider. The traverse motor and transmission belt drive the push fork to achieve high-precision horizontal positioning; the guide rail and slider ensure smooth movement.

[0014] Furthermore, this design also includes a lifting linear module. Two sets of lifting linear modules are mounted on the frame. A lifting connecting seat is located on one side of each lifting linear module near the lifting fork, and the lifting connecting seat is connected to the output end of the lifting linear module. The lifting linear module provides stable lifting power, with fast response and accurate positioning. The dual modules synchronously control the lifting fork, avoiding the risk of the tobacco stack slipping due to tilting.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model improves both the smoke pusher and the smoke receiving plate into a forked type to achieve staggered action. It can not only achieve the functions of the original but also adds a forked smoke receiving plate (lifting smoke receiving fork). The smoke pusher can push smoke at any height when the smoke is stopped, thus realizing the closing of the pack.

[0016] 2. This utility model can achieve the minimum number of cigarette packs per household, indirectly improving energy efficiency and reducing packaging material costs.

[0017] 3. For sorting lines, it allows for more convenient and flexible layout (you can have all customers use one entrance, or you can have two separate entrances for even distribution of smoke).

[0018] 4. The fork of the cigarette pusher always stays within the fork of the lifting and lowering mechanism, achieving a non-interference and durable effect.

[0019] 5. The lifting and lowering smoke fork adopts a frame structure. When it is at its upper limit, the frame against the side of the transfer chain conveyor can act as a smoke barrier to reduce smoke damage, providing a multi-functional effect. At the same time, the original smoke baffle is eliminated, reducing two actions, increasing efficiency, and reducing malfunctions. Attached Figure Description

[0034] Example 1 like Figure 1-8 As shown, a multifunctional packing device for tobacco logistics includes a push fork 1, a lifting fork 2, and a transfer chain conveyor 3. The push fork 1 and the lifting fork 2 are arranged on one side of the transfer chain conveyor 3. The push fork 1 can perform horizontal telescopic movement relative to the transfer chain conveyor 3, such as by hydraulic telescopic movement or linear module drive. The lifting fork 2 can perform lifting movement relative to the transfer chain conveyor 3, such as by screw structure, hydraulic structure, or gear and rack structure drive. The forks of the push fork 1 and the lifting fork 2 are staggered. The fork of the push fork 1 enters between the forks of the lifting fork 2. After the tobacco stack enters the lifting fork 2, the push fork 1 pushes the tobacco stack on the lifting fork 2 onto the transfer chain conveyor 3.

[0035] Another preferred structural arrangement is that the push fork 1 and the lifting fork 2 are respectively provided on the left and right sides of the transfer chain conveyor 3, forming a double-inlet structure at the feed inlet of the transfer chain conveyor 3.

[0036] Example 2 This embodiment provides a specific structure for a cigarette pusher 1 based on Embodiment 1. The cigarette pusher 1 includes a cigarette pusher plate 4 and an integrated base 5. Multiple cigarette pusher plates 4 are arrayed on the integrated base 5. The integrated base 5 is made of a rectangular tube, such as a square tube, and the cigarette pusher plate 4 is made of a hollow rectangular thin plate. An insertion hole 6 is provided on the integrated base 5, and an insertion slot 7 is provided at the lower end of the cigarette pusher plate 4. The lower end of the cigarette pusher plate 4 is inserted into the side wall of the integrated base 5 on one side of the insertion hole 6 through the insertion slot 7. The insertion hole 6 penetrates the integrated base 5, and the lower end of the cigarette pusher plate 4 is flush with the lower surface of the integrated base 5, forming a stable connection structure.

[0037] Example 3 This embodiment provides a specific structure for a lifting cigarette fork 2 based on embodiment 2. The lifting cigarette fork 2 includes a rectangular cigarette receiving frame and an integrated rod. Multiple rectangular cigarette receiving frames are arranged in an array to form a rectangular frame (or a rectangular tube structure). All rectangular cigarette receiving frames are connected by the integrated rod. The integrated base 5 is disposed within the rectangular frame. The cigarette pusher 4 is staggered with the rectangular cigarette receiving frames to form a staggered structure. The lower end of the cigarette pusher 4 is provided with a clearance notch 8.

[0038] More specifically, the rectangular smoke receiving frame includes a C-shaped frame 9 and a partition beam 10 disposed at the opening of the C-shaped frame 9. The partition beam 10 is disposed on one side of the C-shaped frame 9. When multiple rectangular smoke receiving frames are arranged in an array, the partition beam 10 acts as a partition to separate adjacent C-shaped frames 9 into a gap array structure. Both the C-shaped frame 9 and the partition beam 10 are made of rectangular tubing. The integrated rod is a screw (thread not shown in the attached figure). A connecting hole is provided at the connection between the rectangular smoke receiving frame and the integrated rod. A nut sleeve 11 is disposed in the connecting hole, and the nut sleeve 11 is threadedly connected to the integrated rod.

[0039] Preferably, the integrated rod includes a first integrated rod 12, a second integrated rod 13, and a third integrated rod 14 respectively disposed at three corners of the lifting cigarette fork 2. The first integrated rod 12 is also provided with a spacer 15, and a spacer 15 is provided between each pair of rectangular cigarette forks to ensure stable separation between each pair of rectangular cigarette forks.

[0040] Example 4 This embodiment, based on embodiment 3, provides a specific telescopic structure for the push fork 1 and a lifting structure for the lifting connecting fork 2. In this embodiment, the multi-functional packing device further includes a frame 16, a transverse motor 17, and a transmission belt 18. The transverse motor 17 and transmission belt 18 are mounted on the frame 16. The output end of the transverse motor 17 is connected to the transmission belt 18 and can drive it to rotate in both directions (this is achievable with existing technology and will not be elaborated further). The push fork 1 is provided with a transverse connecting seat 19, which is fixedly connected to the transmission belt 18. The forward and reverse rotation of the transmission belt 18 drives the transverse connecting seat 19 to reciprocate, thereby realizing the horizontal telescopic movement of the push fork 1 relative to the transfer chain plate machine 3. A boss 20 is provided under the push fork 1, a guide rail 21 is provided on the frame 16, and a slider 22 is provided on the guide rail 21. The boss 20 is connected to the slider 22.

[0041] More specifically, it also includes a lifting linear module 23. Two sets of lifting linear modules 23 are provided on the frame 16. Two lifting connecting seats 24 are respectively provided on the side of the lifting connecting cigarette fork 2 near each set of lifting linear modules 23. The lifting connecting seats 24 are connected to the output end of the lifting linear module 23 (the existing linear module can be used for this purpose).

[0042] When using the dual-inlet structure for combined packing, assuming that the lifting fork 2 on the left side of the transfer chain conveyor 3 receives tobacco stack A, and the lifting fork 2 on the right side of the transfer chain conveyor 3 receives tobacco stack B, the lifting fork 2 on the left side of the transfer chain conveyor 3 is lowered to its lowest position, and the lifting fork 2 on the right side of the transfer chain conveyor 3 is raised until the tobacco stack B is higher than the tobacco stack A. Then, the pushing forks 1 on the left and right sides of the transfer chain conveyor 3 push tobacco stack A and tobacco stack B into the transfer chain conveyor 3 for combined packing. During the process of pushing the tobacco stacks into the transfer chain conveyor 3, the lifting forks 2 on the opposite side can be used as smoke baffles to reduce tobacco loss.

[0043] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
