Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging, and in particular to a dual-inlet full-specification cigarette packaging machine. Background Technology

[0002] One type of packaging machine, as commonly known, is used to stack rectangular packages of items such as cigarettes according to a set quantity, then place a label on the stacked items, and finally seal the stack with film. (Reference) Figure 1 , Figure 2 This type of packaging machine includes a frame 6' and a conveying device 1', a counting device 2', a palletizing device 3', a film sealing device 4', a label dispensing device 5', and a flipping device 7' mounted on the frame 6'. The conveying device 1' uses an upper pressure pulley 11' and a lower pressure pulley 12' to clamp and convey strip-shaped items onto the flipping device 7'. After receiving a set number of items to be packaged, the flipping device 7' rotates one position, causing the strip-shaped items to flip downwards and fall onto the receiving device 8' of the palletizing device 3'. The counting... Device 2' is located at the outlet of conveying device 1' and is used to count the strip-shaped items entering the flipping device 7'. The film sealing device 4' is used to cover the stacked strip-shaped items with a layer of plastic film, and at the same time, cut and seal the plastic film at the joint position. The above-mentioned mechanisms and their relative positions are clearly described in the patent document disclosed in Chinese Patent CN2595676, published on December 31, 2003, namely, Automatic Film Sealing Heat Shrink Packaging Machine with Precision Guiding Mechanism, and will not be described in detail here.

[0003] In the current cigarette packaging industry, there are numerous specifications for cigarette cartons, covering both standard and irregularly shaped cigarettes. The main differences between these different specifications lie in their width and thickness. The industry generally refers to packaging that covers such diverse specifications as full-specification cigarette carton packaging. Under certain specific market demands, it is often necessary to combine cartons of cigarettes of different lengths into a single, complete product unit for sale. However, conventional packaging machines simply cannot meet this special packaging requirement.

[0004] Currently, the standard packaging process for all types of cigarette cartons typically involves first stacking regular cigarettes according to requirements, then using a multi-axis robot to pick up irregularly shaped cigarettes and precisely place them on top of the stacked regular cigarettes. Finally, the assembled cartons are sent to a sealing device to complete the sealing process. However, this packaging method has significant drawbacks. Not only is the overall work efficiency relatively low, but the use of multi-axis robots and other equipment also leads to higher packaging costs. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a dual-inlet full-size cigarette packaging machine, which solves the technical problems of low working efficiency and high cost of existing full-size cigarette packaging machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dual-inlet full-specification cigarette packaging machine, comprising a frame and a first input conveyor belt for inputting cigarettes, a first buffer conveyor belt for buffering and collecting cigarettes, a first stacking device for conveying cigarettes from top to bottom, a first receiving device for receiving cigarettes located below the first stacking device, and an output conveyor belt for outputting cigarettes after palletizing. A first baffle mechanism is provided on the side of the first buffer conveyor belt near the first stacking device. The first stacking device includes a stacking support, two sets of rotating mechanisms rotatably mounted on the stacking support, and a rotating drive mechanism for driving the rotating mechanisms. The rotating mechanism includes two rotating shafts, two tracks, and multiple blades. The corresponding blades on the two rotating mechanisms cooperate to receive and convey cigarettes.

[0007] The frame is provided with a second input conveyor belt, a second buffer conveyor belt, a second stacking device and a second receiving device on one side of the first input conveyor belt in the order of the production line. The second stacking device is located on one side of the first stacking device, and a second material blocking mechanism is provided on the side of the second buffer conveyor belt close to the second stacking device.

[0008] The second receiving device is provided with a pushing mechanism for pushing the cigarette packs on the second receiving device to the first receiving device;

[0009] The blade is provided with at least one stepped portion, and the stepped portions of the corresponding blades on the two rotating mechanisms form a restricting structure for restricting the cigarette strip.

[0010] Furthermore, the first stacking device and / or the second stacking device are provided with a stacking buffer mechanism for buffering when cigarettes are input, the stacking buffer mechanism including a stacking buffer baffle and a stacking buffer sponge disposed inside the buffer baffle.

[0011] Furthermore, an anti-jump guide plate is provided on the stacked buffer baffle extending towards the stacked buffer sponge. The free end of the anti-jump guide plate is provided with an arc segment, and the anti-jump guide plate is inclined upward with an inclination angle of less than 5°.

[0012] Furthermore, a material blocking and buffering mechanism is provided on the frame below the first stacking device and on one side of the first receiving device. The material blocking and buffering mechanism is used to buffer the cigarettes input by the second receiving device. The material blocking and buffering mechanism includes a material blocking plate and a material blocking and buffering sponge provided on the material blocking plate.

[0013] Furthermore, the number of stepped sections is two, and the blades are made of engineering plastic.

[0014] Furthermore, the pushing mechanism includes an electric cylinder and a push plate disposed on the electric cylinder.

[0015] Furthermore, the first and / or second blocking mechanisms include a blocking cylinder and a blocking plate disposed on the piston rod of the blocking cylinder.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] 1. A second input conveyor belt, a second buffer conveyor belt, a second stacking device, and a second receiving device are installed on the frame along the production line, forming a dual-inlet structure. This allows the packaging machine to process cigarettes from two input production lines simultaneously. The second stacking device is located next to the first stacking device; the two stacking devices operate independently yet cooperate with each other. The second receiving device is equipped with a pushing mechanism that pushes the cigarettes from the second receiving device onto the first receiving device, achieving centralized output of cigarettes from both production lines and facilitating subsequent palletizing and packaging processes.

[0018] At least one step is provided on the blade, and the steps on the corresponding blades on the two rotating mechanisms form a restraining structure for the cigarette packs. This structure can more stably receive and transport the cigarette packs, preventing them from sliding or shifting during transport. Especially when packaging cigarette packs of different lengths, a single stacking device can be reasonably shared.

[0019] 2. A stacking buffer mechanism is provided on the first stacking device and / or the second stacking device, including a stacking buffer baffle and a stacking buffer sponge disposed inside the buffer baffle. When the cigarette packs are input into the stacking device, the stacking buffer sponge can act as a buffer, absorbing the impact force of the cigarette packs, thereby achieving better arrangement and stability. An anti-jump guide plate is provided on the stacking buffer baffle extending towards the stacking buffer sponge, and the free end of the anti-jump guide plate is provided with an arc segment and tilted upwards at an angle of less than 5°. This can guide the cigarette packs when they are input into the stacking device, preventing the cigarette packs from jumping during the input process, allowing the cigarette packs to enter the stacking device more smoothly, and further improving the stability of the cigarette packs during the stacking process.

[0020] 3. The material blocking and buffering mechanism can effectively buffer the tobacco strips input from the second receiving device to the first receiving device, thereby achieving stacking stability.

[0021] 4. There are two steps, which can accommodate both long and short cigarettes, thus achieving effective restriction. That is, the two ends of the long cigarette are restricted by one step, and the two ends of the short cigarette are restricted by the other step.

[0022] 5. The first and second baffle mechanisms are mainly used to restrict the movement of cigarette packs. Attached Figure Description
