Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging machine technology, and in particular to a cigarette protection conveying channel at the outlet of a carton packaging machine. Background Technology

[0002] During the production process of the ZB25 / 45 cigarette packaging machine, cigarette packs sometimes become clogged as they are conveyed through the output channel at the CV packing machine outlet. Once clogged, the cigarette packs are pressed together and block the entire channel. Due to the high height of the side walls and their non-removable nature, cleaning after the clog is difficult, with an average processing time of 15 minutes, which affects the effective operating rate of the equipment. If not handled in time, it can also cause a large number of cigarette packs to pile up, resulting in damage to the appearance of the cigarette packs and increasing the production costs of the enterprise. In severe cases, the stacking of cigarette packs can even damage the equipment. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a smoke protection conveying channel at the outlet of a packing machine, which solves the problem that the side walls of the conveying channel in the prior art are too high and cannot be disassembled, making it difficult to clean after blockage.

[0004] This utility model solves the above-mentioned technical problems through the following technical means: a cigarette packing machine outlet protective conveying channel, including a bottom conveying surface for conveying cigarette packs, a fixed guide plate on one side of the bottom conveying surface, and a movable guide plate assembly on the other side, the movable guide plate assembly including a base and a flow guide plate, one end of the flow guide plate being rotatably connected to the base in the horizontal direction, and the other end being rotatable along an arc groove opened on the base, the flow guide plate being provided with at least three detachable guide strips, the bottom edge of the guide strips being flush with the bottom edge of the cigarette pack, and the top edge of the guide strips being lower than the top edge of the cigarette pack.

[0005] Optionally, the guide plate is fixedly connected to a vertical shaft corresponding to the bottom of the arc-shaped groove, and a roller is rotatably connected to the vertical shaft, the roller being able to roll along the arc-shaped groove.

[0006] Optionally, the base may also have an elastic element at one end with an arc-shaped groove to allow the flow guide plate to return to its initial position.

[0007] Optionally, it also includes a detection module and a controller, the detection module comprising:

[0008] A first sensor is installed at the entrance of the conveyor channel to detect the stacking height;

[0009] The second sensor is a set of two sets of through-beam sensors arranged at intervals along the cigarette conveying direction, with the interval being greater than the width of a preset number of individual cigarettes.

[0010] A third sensor is installed at the outlet of the conveying channel to detect the lateral pressure on the cigarette stick;

[0011] The first sensor, the second sensor, and the third sensor are all connected to the controller via signal connection.

[0012] Optionally, the first sensor is installed at a height higher than the top edge of the cigarette bar and lower than the height of the two cigarette bars stacked together.

[0013] Optionally, the third sensor is a pressure sensor, which is embedded in the inner wall of the last guide strip and flush with the contact surface of the cigarette strip.

[0014] Optionally, the controller is connected to an audible and visual alarm device.

[0015] Optionally, the arc-shaped groove is further provided with a limiting block that can be adjusted and fixed in position along the arc-shaped groove. This is used to adjust and limit the movable range of the flow guide plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model solves the problem of difficult cleaning after blockage caused by the high and non-removable sidewalls of the conveying channel in existing technologies by designing a movable guide plate assembly and detachable guide strips. When the conveying channel becomes blocked, operators can quickly remove the guide strips or rotate the guide plate to expand the operating space, making it easier to clean the blocked smoke bars, greatly shortening the blockage handling time and improving the effective operating rate of the equipment.

[0018] 2. When the cigarette sticks are slightly stacked (i.e., two layers of cigarette sticks are stacked), the top edge of the guide bar is lower than the top edge of the cigarette sticks, so the operator can directly remove the stacked cigarette sticks from above without disassembling the equipment, which further improves the processing efficiency.

[0019] 3. This utility model, through the combined use of the detection module and the controller, can promptly detect and handle abnormal situations in the conveying channel. Specifically, the first sensor can detect the stacking height of the cigarette sticks, the second sensor can monitor the conveying speed of the cigarette sticks, and the third sensor can detect the lateral pressure on the cigarette sticks. When any parameter is abnormal, the controller can issue an alarm or take corresponding measures, thereby reducing production costs, reducing the risk of equipment damage, and improving production efficiency.

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0027] like Figures 1-4 As shown, this utility model provides a cigarette packing machine outlet cigarette conveying channel, including a bottom conveying surface 1 for conveying cigarettes. The bottom conveying surface 1 can be an existing conveyor belt structure. A fixed guide plate 21 is provided on one side of the bottom conveying surface 1, and a movable guide plate assembly is provided on the other side. The bottom conveying surface 1, the movable guide plate assembly, and the fixed guide plate 21 together form a cigarette conveying channel.

[0028] In this embodiment, the movable guide plate assembly includes a base 22 and a flow guide plate 23. One end of the flow guide plate 23 is rotatably connected to the base 22 in the horizontal direction, and the other end can rotate along the arc groove 221 opened on the base 22. The flow guide plate 23 is provided with at least three detachable guide strips 231. The bottom edge of the guide strip 231 is flush with the bottom edge of the cigarette bar, and the top edge of the guide strip 231 is lower than the top edge of the cigarette bar.

[0029] In this embodiment, the flow guide base plate 23 is fixedly connected to the bottom of the arc groove 221 with a vertical shaft 232. A roller is rotatably connected to the vertical shaft 232. The roller can roll along the arc groove 221. For example, the roller is made of nylon material, with a diameter of 15-20 mm and a thickness of 8-10 mm. It is equipped with bearings to ensure flexible rotation. The roller can roll along the arc groove 221, so that the flow guide base plate 23 can be adjusted smoothly.

[0030] In this embodiment, one end of the base 22 with the arc-shaped groove 221 is also provided with an elastic element for restoring the flow guide plate 23 to its initial position. For example, the elastic element is a tension spring, one end fixed to the base 22 and the other end fixed to the flow guide plate 23. The tension spring has moderate elasticity, allowing the flow guide plate 23 to flexibly adjust its position when subjected to external force, and automatically return to its initial position after the external force disappears. The tension spring is made of stainless steel, with a wire diameter of 0.8-1.2 mm and a free length of 30-50 mm.

[0031] In this embodiment, a limiting block that can be adjusted and fixed along the arc groove 221 is also provided on the arc groove 221. Specifically, the limiting block is a rectangular block with a size larger than the width of the arc groove 221. A threaded hole is provided in the middle of the limiting block. The hexagonal head of one end of the bolt is larger than the width of the arc groove 221, and the other end is fitted with a nut. The limiting block is fastened by the bolt passing through the threaded hole. The setting of the limiting block is used to limit the range of motion of the guide plate 23.

[0032] In this embodiment, the smoke-protecting conveying channel further includes a detection module and a controller. The detection module includes:

[0033] A first sensor 31 is installed at the entrance of the conveyor channel to detect the stacking height. For example, the first sensor 31 is a photoelectric sensor, installed above the entrance of the conveyor channel, at a height higher than the top edge of the tobacco sticks but lower than the height of two tobacco sticks stacked together. Specifically, if the height of a single tobacco stick is 50 mm, the installation height of the first sensor 31 is 65-85 mm. This design aims to detect whether tobacco sticks are stacked. The first sensor 31 can be fixed to the frame of the conveyor channel by a bracket, and its position can be finely adjusted to accommodate tobacco sticks of different sizes.

[0034] A second sensor 32, positioned in the middle of the conveying channel to detect the speed of the cigarette packs, consists of two sets of through-beam sensors spaced apart along the conveying direction. The distance between these sensors is greater than the width of a preset number of individual cigarette packs; typically, it is the width of 3-5 cigarette packs. For example, if the width of an individual cigarette pack is 125 mm, the distance between the two sets of sensors would be 375-625 mm. The second sensor 32 can also be fixed to both sides of the conveying channel by brackets, at a height flush with the middle of the cigarette packs, to ensure accurate detection of the cigarette packs' passage.

[0035] A third sensor 33 is installed at the outlet of the conveying channel to detect the lateral pressure on the tobacco sticks. For example, the pressure sensor is a thin-film type with a thickness not exceeding 1 mm and a sensing area of ​​20 × 20 mm, capable of accurately detecting the lateral pressure on the tobacco sticks. The selected pressure sensor has a range of 0-10 Newtons and an accuracy of 0.1 Newtons, enabling it to sensitively detect changes in lateral pressure on the tobacco sticks during conveying.

[0036] The first sensor 31, the second sensor 32, and the third sensor 33 are all connected to the controller. The controller is a programmable logic controller (PLC), which can be set up independently or integrated into the control cabinet of an existing cigarette packing machine. It typically has multiple input / output interfaces and can receive and process signals from each sensor in real time. Based on the received signals, the controller determines the cigarette pack conveying status and issues an alarm or adjusts the conveying parameters when necessary.

[0037] Specifically: the controller determines whether the tobacco strips are stacked based on the signal from the first sensor 31; it calculates the conveying speed of the tobacco strips based on the signal from the second sensor 32; and it monitors the lateral pressure on the tobacco strips based on the signal from the third sensor 33, issuing an alarm or reminder to adjust the position of the guide plate 23 when the pressure exceeds a preset threshold. The controller is also connected to common audible and visual alarm devices. It typically also has data storage and analysis functions, recording various parameters during the conveying process to provide a basis for equipment maintenance and process optimization, which will not be elaborated upon here.

[0038] The working principle of this utility model is as follows:

[0039] When in use, the cigarette packing conveying channel of this utility model allows the cigarette sticks to enter the conveying channel from the cigarette packing machine outlet and be conveyed forward along the channel between the fixed guide plate 21 and the movable guide plate assembly on the bottom conveying surface 1.

[0040] When the number of cigarette sticks increases or the conveying speed changes, causing an increase in the lateral pressure on the cigarette sticks in the channel, the guide plate 23 in the movable guide plate assembly will rotate along the arc-shaped groove 221 under the action of external force, increasing the channel width, reducing the lateral pressure on the cigarette sticks, and preventing the cigarette sticks from deforming or being damaged. When the number of cigarette sticks decreases or the conveying speed returns to normal, the guide plate 23 will automatically return to its initial position under the action of the elastic element.

[0041] During this process, the first sensor 31 monitors the stacking of cigarette sticks at the entrance of the conveying channel in real time. If stacking is detected, the controller will trigger an alarm to remind the operator to adjust the conveying speed of the upstream equipment. The second sensor 32 monitors the conveying speed of the cigarette sticks. If an abnormal conveying speed is detected, the controller will issue an alarm or adjust the conveying parameters. The third sensor 33 monitors the lateral pressure on the cigarette sticks. If the pressure exceeds a preset threshold, the controller will issue an alarm or remind the operator to adjust the position of the guide plate 23.

[0042] Through the above design, the cigarette packing machine's outlet cigarette conveying channel can adapt to the cigarette packing needs under different working conditions, effectively preventing the cigarette packs from deforming, being damaged, or stacking during the conveying process, thus improving the stability and reliability of cigarette pack conveying.
