Description

Technical Field

[0001] This application relates to the field of cigarette pack paper positioning technology, and in particular to a cigarette pack paper positioning device and a cigarette packaging machine. Background Technology

[0002] In the cigarette production process, cigarette wrapping paper is used to wrap cigarettes, and its positioning accuracy directly affects the appearance quality and packaging efficiency of the finished cigarette pack. To ensure that the cigarette wrapping paper remains stable during conveying and folding, a cigarette wrapping paper positioning device is usually required to reduce skewing and slippage caused by mechanical vibration or conveying deviation during high-speed movement.

[0003] In existing technologies, common cigarette pack positioning methods mainly rely on paper hooks for fixation. Specifically, these hooks are placed along the movement path of the cigarette pack to position it. However, this structure only provides contact constraint in one direction and cannot effectively suppress the skewing and movement of the cigarette pack in other directions. Due to the limited contact area between the paper hook and the cigarette pack, the pack is still prone to shifting and moving when affected by airflow disturbances or mechanical vibrations, leading to inaccurate positioning. Utility Model Content

[0004] Therefore, it is necessary to provide a cigarette pack positioning device and a cigarette packaging machine that can solve the above problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A cigarette packing paper positioning device is used to position the end of the cigarette packing paper in a first direction during cigarette packaging. The cigarette packing paper positioning device includes:

[0007] The motherboard has a first end and a second end that are opposite to each other in a first direction, a first side and a second side that are opposite to each other in a second direction, and a mating surface in a third direction. The first direction, the second direction and the third direction constitute a three-dimensional coordinate system.

[0008] The positioning block includes a first positioning block and a second positioning block, wherein the first positioning block is disposed on the first side and the second positioning block is disposed on the second side;

[0009] A paper receiving hook is disposed at the second end of the main board and spaced apart between the mating surface and the third-party upward direction;

[0010] A negative pressure adsorption system is installed on the main board and is able to create negative pressure on the mating surface;

[0011] A limiting space is formed between the mating surface, the first positioning block, the second positioning block, and the paper receiving hook, and the limiting space is used to limit the end of the cigarette pack paper.

[0012] Understandably, this application, by setting up a main board, positioning blocks, paper hooks, and a negative pressure adsorption system, positions the cigarette pack paper when it enters the cigarette pack paper positioning device. This is achieved by utilizing the limiting space formed by the mating surfaces on the main board, the first positioning block, the second positioning block, and the paper hook. Specifically, the first positioning block, the second positioning block, and the paper hook position the cigarette pack paper at both ends in the second direction and at the end in the first direction, respectively. The negative pressure adsorption system then adsorbs the cigarette pack paper, causing it to adhere to the main board and move within the limiting space along the first direction. This prevents the cigarette pack paper from tilting or shifting during positioning, thereby enhancing the positioning accuracy and stability of the cigarette pack paper and reducing the defect rate when packaging cigarettes.

[0013] In one embodiment, two negative pressure adsorption systems are provided, with the two negative pressure adsorption systems correspondingly disposed at the first and second ends of the motherboard.

[0014] Understandably, by setting two adsorption systems at the first and second ends of the motherboard, the negative pressure adsorption system at the first end can guide the cigarette pack paper into the limiting space and move along the mating surface in the first direction, while the negative pressure adsorption system at the second end can guide the cigarette pack paper to smoothly contact the paper receiving hook. The setting of the two negative pressure adsorption systems can guide the cigarette pack paper to move stably along the mating surface, prevent the cigarette pack paper from bending or shifting, and improve the accuracy of the cigarette pack paper positioning.

[0015] In one embodiment, the negative pressure adsorption system includes an air inlet channel, an air outlet, an air return channel, and a groove formed on the mating surface, wherein the air inlet channel is located on the main board.

[0016] The groove has a first groove wall and a second groove wall that are arranged opposite to each other in the first direction. The air outlet is opened on the first groove wall and communicates with the air inlet channel and can discharge air in the first direction. The air return hole is opened on the second groove wall.

[0017] In one embodiment, the number of air outlets is set to multiple, and the multiple air outlets are spaced apart in the second direction.

[0018] In one embodiment, the number of the return air holes is set to multiple, and the multiple return air holes are spaced apart in the second direction.

[0019] In one embodiment, an air outlet is arranged between two adjacent air return holes.

[0020] In one embodiment, the groove extends along the second direction and penetrates the motherboard.

[0021] In one embodiment, the angle between the second groove wall and the first direction is A, where 180° > A ≥ 150°.

[0022] In one embodiment, in the first direction, both the first positioning block and the second positioning block are provided with a first guide slope at the end position near the first end, and the two first guide slopes form a funnel-shaped opening; wherein, the larger diameter end of the funnel-shaped opening is provided facing the first end.

[0023] And / or, the paper hook has a second guide ramp, which is inclined in the direction away from the mating surface in the third direction.

[0024] This application also provides the following technical solutions:

[0025] A cigarette packaging machine includes a cigarette pack paper positioning device as described in any of the above embodiments.

[0026] Compared with existing technologies, the cigarette pack positioning device, by setting up a main board, positioning blocks, paper hooks, and a negative pressure adsorption system, positions the cigarette pack when it enters the device. This is achieved by utilizing the limiting space formed by the mating surfaces on the main board, the first positioning block, the second positioning block, and the paper hook. Specifically, the first positioning block, the second positioning block, and the paper hook position the cigarette pack at both ends in the second direction and at the end in the first direction, respectively. The negative pressure adsorption system adsorbs the cigarette pack, causing it to adhere to the main board and move within the limiting space along the first direction. This prevents the cigarette pack from tilting or shifting during positioning, thereby enhancing the positioning accuracy and stability of the cigarette pack and reducing the defect rate when packaging cigarettes.

[0038] Please see Figures 1 to 3 This application provides a cigarette wrapping paper positioning device 100, which is used to position the end of the cigarette wrapping paper in a first direction X during cigarette packaging. Here, the cigarette wrapping paper is generally aluminum foil.

[0039] Specifically, the cigarette pack paper positioning device 100 includes a main board 10, a positioning block 20, a paper receiving hook 30, and a negative pressure adsorption system 40. The main board 10 has a first end 11 and a second end 12 arranged opposite to each other in the first direction X, a first side 13 and a second side 14 arranged opposite to each other in the second direction Y, and a mating surface 15 in the third direction Z. The first direction X, the second direction Y, and the third direction Z constitute a three-dimensional coordinate system. The positioning block 20 includes a first positioning block 21 and a second positioning block 22. The first positioning block 21 is located on the first side 13, and the second positioning block 22 is located on the second side 14. The paper receiving hook 30 is located at the second end 12 of the main board 10 and is spaced apart from the mating surface 15 in the third direction Z. The negative pressure adsorption system 40 is located on the main board 10 and can form a negative pressure on the mating surface 15. A limiting space 50 is formed between the mating surface 15, the first positioning block 21, the second positioning block 22, and the paper receiving hook 30. The limiting space 50 is used to limit the end of the cigarette pack paper. Thus, by setting up the main board 10, positioning block 20, paper hook 30, and negative pressure adsorption system 40, when the cigarette pack paper enters the cigarette pack paper positioning device 100, the limiting space 50 formed by the mating surface 15 on the main board 10, the first positioning block 21, the second positioning block 22, and the paper hook 30 is used to position the cigarette pack paper. Specifically, the first positioning block 21, the second positioning block 22, and the paper hook 30 are used to position the two ends of the cigarette pack paper in the second direction Y and the end in the first direction X, respectively. The negative pressure adsorption system 40 is used to adsorb the cigarette pack paper, so that it is attached to the main board 10 and moves along the first direction X within the limiting space 50. This can prevent the cigarette pack paper from being skewed or moving during positioning, thereby improving the positioning accuracy and stability of the cigarette pack paper and reducing the defect rate of the cigarette pack paper when packaging cigarettes.

[0040] like Figure 1 and Figure 2 As shown, in the first direction X, both the first positioning block 21 and the second positioning block 22 are provided with a first guide slope 23 at their ends near the first end 11, and the two first guide slopes 23 form a funnel-shaped opening 24; wherein, the larger diameter end of the funnel-shaped opening 24 faces the first end 11. In this way, by providing the first guide slope 23 to guide the cigarette pack paper, the cigarette pack paper can be stably moved to the limiting space 50 along the first direction X.

[0041] In one embodiment, the paper receiving hook 30 has a second guiding slope 31, which is inclined in the third direction Z away from the mating surface 15. When the cigarette pack paper moves quickly to the second end 12, the second guiding slope 31 can continue to guide the cigarette pack paper, thereby enabling it to move into place well.

[0042] Furthermore, the number of paper-receiving hooks 30 is set to multiple, and the multiple paper-receiving hooks 30 are arranged at intervals along the second direction Y, so that the end of the cigarette pack paper can be supported at multiple points in the changed position, thereby more stably limiting the position of the cigarette pack paper. Here, the number of paper-receiving hooks 30 can be two, three, or four, etc.

[0043] In one embodiment, one end of the paper hook 30 can be fixed to the second end 12 of the main board 10 by means of a screw or other component. The other end of the paper hook 30 extends to the mating surface 15 on the front side in the third direction Z, and forms a gap therebetween.

[0044] In one embodiment, two negative pressure adsorption systems 40 are provided, correspondingly located at the first end 11 and the second end 12 of the main board 10. By providing two adsorption systems at the first end 11 and the second end 12 of the main board 10, the negative pressure adsorption system 40 located at the first end 11 can guide the cigarette pack paper into the limiting space 50 and move along the mating surface 15 in the first direction X, while the negative pressure adsorption system 40 located at the second end 12 can guide the cigarette pack paper to smoothly contact the paper receiving hook 30. The arrangement of the two negative pressure adsorption systems 40 can guide the cigarette pack paper to move stably along the mating surface 15, preventing the cigarette pack paper from bending or shifting, and improving the accuracy of the cigarette pack paper positioning.

[0045] Of course, this is not the only option; the number of negative pressure adsorption systems 40 can be set to other quantities, depending on actual needs.

[0046] Please continue to refer to this. Figure 1 and Figure 2 The negative pressure adsorption system 40 includes an air inlet channel 41, an air outlet 42, an air return hole 43, and a groove 44 formed on the mating surface 15. The air inlet channel 41 is located on the main board 10. The groove 44 has a first groove wall 441 and a second groove wall 442 arranged opposite to each other in the first direction X. The air outlet 42 is located on the first groove wall 441 and communicates with the air inlet channel 41, and can exhaust air in the first direction X. The air return hole 43 is located on the second groove wall 442. By setting the groove 44 and opening the air outlet 42 on its first groove wall 441, the airflow is blown out in the first direction X, which can make the cigarette pack paper adhere to the mating surface 15. At the same time, the second groove wall 442 has an air return hole 43, and the airflow from the air outlet 42 can be discharged through the air return hole 43. Thus, a negative pressure is formed near the mating surface 15, which can make the cigarette pack paper fall against the mating surface 15.

[0047] In one embodiment, the number of air outlets 42 is set to multiple, and the multiple air outlets 42 are spaced apart in the second direction Y. In this way, by setting multiple air outlets 42, the airflow can be dispersed, avoiding excessive airflow at a single point that could cause local deformation or uneven adsorption of the cigarette pack paper, thereby improving the stability of the adhesion between the cigarette pack paper and the mating surface 15. Here, the number of air outlets 42 can be 3, 5, 7, 8, etc.

[0048] Preferably, the multiple air outlets 42 are evenly spaced along the second direction Y, so that the airflow can be evenly distributed.

[0049] In one embodiment, the number of return air holes 43 is set to multiple, and the multiple return air holes 43 are arranged at intervals in the second direction Y. In this way, by providing multiple air outlet holes 42, an airflow circulation can be formed with the airflow blown out of the air outlet holes 42, and the airflow blown out of the air outlet holes 42 can flow out from the nearby return air holes. Here, the number of air outlet holes 42 can be 4, 6, 8, 9, etc.

[0050] In one embodiment, an air outlet 42 is arranged between two adjacent air return holes 43. Furthermore, the number of air return holes 43 is greater than the number of air outlet holes 42. This arrangement allows the airflow from the air outlet holes 42 to be discharged promptly through the nearby air return holes 43, preventing uneven local negative pressure that could lead to poor adhesion between the cigarette wrapping paper and the mating surface 15. On the other hand, the cooperation between the air outlet holes 42 and the air return holes 43 creates multiple circulation points for adsorbed airflow in the second direction Y, improving the stability of the cigarette wrapping paper's adhesion.

[0051] like Figures 1 to 3 As shown, the groove 44 extends along the second direction Y and penetrates the main board 10. With this configuration, the groove 44 as a whole also forms a return air channel, allowing the gas discharged from the vent 42 to be discharged in a timely manner, thereby improving the stability of the cigarette pack paper's adhesion.

[0052] In one embodiment, reference Figure 3 The second groove wall 442 is set as an inclined surface, and the angle between the inclined surface and the first direction X is A, where 180°>A≥150°. In this way, while ensuring that the second groove wall 442 is inclined relative to the main board 10 to form a groove 44, it can prevent the cigarette pack paper from bending along the second groove wall 442 due to the angle between the inclined surface and the first direction X being too small. Therefore, while meeting the return air requirement, the cigarette pack paper will not bend due to the angle of the second groove wall 442 being too small, so that the cigarette pack paper can maintain a stable fit with the mating surface 15 and move downward.

[0053] Optionally, the value of A can be 150°, 160°, 165°, 170°, 179°, etc. Of course, it is not limited to these values; the value of A can be set according to actual needs and is not restricted here.

[0054] Furthermore, the negative pressure adsorption system 40 also includes an air inlet pipe (not shown) and a speed control valve (not shown). One end of the air inlet pipe is connected to the air inlet channel 41, and the other end is connected to the air pump for supplying air to the air inlet channel 41. The speed control valve is installed on the air inlet pipe and can control the amount of airflow provided by the air inlet pipe to provide a suitable gas flow rate to achieve negative pressure adsorption between the cigarette pack paper and the mating surface 15.

[0055] like Figures 1 to 3 As shown, the cigarette pack positioning device 100 also includes a mounting bracket 60. The main board 10 is connected to the mounting bracket 60 by screws and is installed in a preset position through the mounting bracket 60.

[0056] This application also provides the following technical solutions:

[0057] A cigarette packaging machine includes a cigarette pack paper positioning device 100 as described in any of the above embodiments.

[0058] In actual use, the cigarette pack paper positioning device 100 is located below the cigarette pack paper cutter. A cigarette pusher plate and a forming chamber are provided between the cigarette pack paper cutter and the cigarette pack paper positioning device 100. After the cigarette pack paper is cut by the cigarette pack paper cutter, the cigarette pack paper enters the cigarette pack paper positioning device 100 at one end along the first direction X. Then, the cigarette pusher plate pushes the cigarette pack and the cigarette pack paper together into the forming chamber, so that the cigarette pack paper is folded into a U-shape and enters the next process.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
