[0001] The present application relates to the technical field of tobacco machinery, and particularly relates to a paper lifting roller limit adjusting mechanism, a tipping paper gluing system, and a cigarette making machine. Background Art

[0002] The tipping paper gluing system is an important part of a cigarette making machine. It uses a rotatable paper lifting roller to lift or lower the tipping paper, controls whether the tipping paper contacts the gluing roller, and further controls whether the gluing roller applies glue to the tipping paper. Generally, the rotation stroke of the paper lifting roller is adjusted by a paper lifting roller limit adjusting mechanism.

[0003] In the related art, the paper lifting roller limit adjusting mechanism generally uses an adjusting screw to adjust the stroke of the paper lifting roller. However, this paper lifting roller limit adjusting mechanism has the problem of inconvenient use, which affects the convenience of adjusting the rotation stroke of the paper lifting roller. Summary of the Invention

[0004] One technical problem to be solved by the present application is to improve the convenience of adjusting the rotation stroke of the paper lifting roller.

[0005] To solve the above technical problem, the present application provides a paper lifting roller limit adjusting mechanism, which includes:

[0006] A mounting seat for connecting to the frame of the tipping paper gluing system; and

[0007] A rotating assembly, including a connecting shaft, a rotating member, and a locking member. The connecting shaft connects the rotating member and the mounting seat to realize the rotatable connection between the rotating member and the mounting seat, so that the rotating member can rotate relative to the mounting seat around the connecting shaft. The locking member connects the rotating member and the mounting seat to lock the rotating member when the rotating member rotates in place around the connecting shaft, so that the rotating member can limit the rotatably arranged paper lifting roller of the tipping paper gluing system on the frame at different angular positions, and realize the adjustment of the rotation stroke of the paper lifting roller.

[0008] In some embodiments, an arc-shaped groove is provided on the rotating member, and a locking hole is provided on the mounting seat. The locking member passes through the arc-shaped groove and the locking hole to connect the rotating member and the mounting seat.

[0009] In some embodiments, the rotating member includes a first rotating portion, a second rotating portion, and a third rotating portion. The second rotating portion is connected between the first rotating portion and the third rotating portion, and protrudes at least on one side in a direction intersecting the sequentially connected direction of the first rotating portion, the second rotating portion, and the third rotating portion in a plane perpendicular to the axial direction of the connecting shaft. The connecting shaft passes through the first rotating portion, and the arc-shaped groove is provided on the second rotating portion.

[0010] In some embodiments, the edge of the protruding portion of the second rotating portion relative to the first rotating portion and the third rotating portion is arc-shaped.

[0011] In some embodiments, the locking hole is a threaded hole, and the locking member is threadedly connected to the locking hole.

[0012] In some embodiments, the paper lifting roller limiting and adjusting mechanism further includes a dial, and the connecting shaft is also connected to the dial to achieve rotatable connection between the rotating member and the dial, so that the rotating member rotates around the connecting shaft and can align with different scales on the dial.

[0013] In some embodiments, the rotating member is provided with a mark, and the mark is used to indicate the scale on the dial aligned by the rotating member.

[0014] In some embodiments, the mark includes a triangle or an arrow.

[0015] In some embodiments, elongated holes are provided on both the mounting base and the dial, and the first connecting member passes through the elongated holes on the mounting base and the dial to connect the dial and the mounting base.

[0016] In some embodiments, the elongated hole is a U-shaped hole.

[0017] In some embodiments, the dial and the rotating member are located on opposite sides of the mounting base.

[0018] In addition, the present application also provides a tipping paper gluing system, which includes a frame and a paper lifting roller. The paper lifting roller is rotatably arranged on the frame, and moreover, it further includes the paper lifting roller limiting and adjusting mechanism according to any embodiment of the present application. The paper lifting roller limiting and adjusting mechanism is arranged on at least one side in the rotation direction of the paper lifting roller, and the rotating member of the paper lifting roller limiting and adjusting mechanism is used to contact the paper lifting roller to limit the rotational displacement of the paper lifting roller on the frame.

[0019] In some embodiments, the axial direction of the connecting shaft of the paper lifting roller limiting and adjusting mechanism is parallel to the rotation axis of the paper lifting roller.

[0020] Furthermore, the present application also provides a cigarette making machine, which includes the tipping paper gluing system according to any embodiment of the present application.

[0021] In the present application, the paper lifting roller limiting and adjusting mechanism no longer relies on adjusting screws to adjust the rotation stroke of the paper lifting roller, but instead relies on a rotating member that can rotate around the connecting shaft to adjust the rotation stroke of the paper lifting roller, which can effectively improve the convenience of adjusting the rotation stroke of the paper lifting roller.

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0039] For technologies, methods, and devices known to those of ordinary skill in the relevant art, they may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification.

[0040] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", and "top, bottom" are usually based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0041] In the description of the present application, it should be understood that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meanings and therefore cannot be understood as a limitation on the protection scope of the present application.

[0042] In addition, the technical features involved in different implementation manners of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] A cigarette usually includes a cigarette section and a filter section. The cigarette section is formed by wrapping tobacco leaves with cigarette paper, and the filter section is formed by wrapping a filter element with tipping paper. The tipping paper is pasted to the cigarette paper. It can be seen that the tipping paper is an important part of the cigarette, and tipping paper gluing is one of the important processes in cigarette production.

[0044] In a cigarette-making machine, a tipping paper gluing system is usually provided to complete the tipping paper gluing process. The glued tipping paper continues to be conveyed downstream and is cut into the required size for wrapping the filter element.

[0045] Figure 1 Exemplarily shows the structure of the tipping paper gluing system.

[0046] Refer to Figure 1 , the tipping paper gluing system 100 includes a frame 40, a tipping paper roller 20 and a gluing roller 30. Among them, the tipping paper roller 20 and the gluing roller 30 are both arranged on the frame 40. The gluing roller 30 is used to transfer glue onto the tipping paper 50. The tipping paper roller 20 is rotatably arranged on the frame 40, which guides the tipping paper 50 to pass through the gluing roller 30, and through its own rotation, raises or lowers the tipping paper 50 to control whether the tipping paper 50 is pressed onto the gluing roller 30, and further controls whether the glue on the gluing roller 30 is applied to the tipping paper 50.

[0047] Generally, the tipping paper roller 20 rotates between a first position and a second position. The rotational displacement of the tipping paper roller 20 between the first position and the second position is called the rotational stroke of the tipping paper roller 20. The rotational stroke of the tipping paper roller 20 affects the pressing degree of the tipping paper roller 20 on the tipping paper 50, and further affects the glue application amount.

[0048] Therefore, the tipping paper gluing system 100 usually also sets a tipping paper roller limit adjusting mechanism 10 to adjust the rotational stroke of the tipping paper roller 20. And, as Figure 1 shown, generally, the tipping paper roller limit adjusting mechanisms 10 are provided on both sides of the rotational direction of the tipping paper roller 20, so that the rotational stroke of the tipping paper roller 20 can be adjusted by restricting and adjusting the bilateral rotational displacement of the tipping paper roller 20.

[0049] In Figure 1 , the tipping paper roller limit adjusting mechanisms 10 are provided on both sides of the rotational direction of the tipping paper roller 20. Figure 1 The two tipping paper roller limit adjusting mechanisms 10 shown both adopt the structural forms in the related art. The structure of the corresponding tipping paper roller limit adjusting mechanism 10 is further shown in Figure 2 and Figure 3 .

[0050] Refer to Figure 2 and Figure 3 , in the related art, the tipping paper roller limit adjusting mechanism 10 includes an adjusting screw 1', a fastening screw 2', a nut 3' and a base 4'. The adjusting screw 1' is used to contact the tipping paper roller 20 to limit the rotational displacement of the tipping paper roller 20. It passes through the base 4' and is threadedly connected to the base 4'. A through hole 5' is provided on the base 4', and the axial direction of the through hole 5' is perpendicular to the axial direction of the adjusting screw 1'. The fastening screw 2' is inserted into the base 4' through the through hole 5' and is threadedly connected to the through hole 5' for fastening the adjusting screw 1'. The nut 3' is sleeved on the adjusting screw 1' and is used to fasten the adjusting screw 1' together with the fastening screw 2'.

[0051] Back to Figure 1, during installation, the axis of the adjusting screw 1' is perpendicular to the rotation axis of the paper lifting roller 20 and is substantially flush with the surface of the machine frame 40 for installing the paper lifting roller limit adjusting mechanism 10 (referred to as the installation surface for short). Moreover, the fastening screw 2' is located on the side of the adjusting screw 1' close to the installation surface of the machine frame 40, and the part of the through hole 5' that is not penetrated by the fastening screw 2' is located on the side of the adjusting screw 1' away from the installation surface of the machine frame 40. That is to say, the part of the through hole 5' that is not penetrated by the fastening screw 2' and the fastening screw 2' are respectively located on the upper side and the lower side of the adjusting screw 1'.

[0052] During the working process, if it is necessary to adjust the rotation stroke of the paper lifting roller 20, it is necessary to first loosen the fastening screw 2' and the nut 3', and then turn the adjusting screw 1' to change the length of the adjusting screw 1' extending from the base 4', so that the adjusting thread 1' can contact the paper lifting roller 20 at different positions in the rotation direction of the paper lifting roller 20, and limit the rotational displacement of the paper lifting roller 20, thereby realizing the adjustment of the rotation stroke of the paper lifting roller 20.

[0053] It has been found in practice that the paper lifting roller limit adjusting mechanism 10 in the above related technologies has the following problems:

[0054] (1) The operation is relatively complex. As mentioned above, when it is necessary to adjust the rotation stroke of the paper lifting roller 20, it is necessary to first loosen two components, namely the fastening screw 2' and the nut 3', with more steps and a relatively complex operation.

[0055] (2) It is not convenient to use tools. Since the axis of the adjusting screw 1' is perpendicular to the rotation axis of the paper lifting roller 20 and is substantially flush with the installation surface of the machine frame 40, in this case, if tools such as a wrench or an Allen key are used to turn the adjusting screw 1', the tools are likely to interfere with other structural components around the paper lifting roller limit adjusting mechanism 10. Therefore, it is not convenient to use tools and the operation is inconvenient.

[0056] (3) The adjustment accuracy is relatively poor. When adjusting the rotation stroke of the paper lifting roller 20, it is impossible to accurately judge whether the adjusting screw 1' has been turned in place, and often multiple adjustments are required to meet the requirements, which affects the efficiency.

[0057] (4) The adjusting screw 1' is easily stuck by glue, causing difficulties in adjustment and disassembly. As mentioned above, during the working process, the through hole 5' faces upward and the adjusting screw 1' is exposed. In this case, the glue splashed during the gluing process is likely to enter the through hole 5', sticking the thread of the adjusting screw 1' and causing the adjusting screw 1' to be stuck and difficult to turn, resulting in difficulties in adjustment and disassembly.

[0058] It can be seen that the paper lifting roller limit adjusting mechanism 10 in the related technologies has the problem of inconvenient use, which affects the convenience of adjusting the rotation stroke of the paper lifting roller.

[0059] Based on the above findings, the present application improves the structure of the paper lifting roller limit adjusting mechanism 10, and provides a more convenient paper lifting roller limit adjusting mechanism 10 to improve the convenience of adjusting the rotation stroke of the paper lifting roller.

[0060] Figures 4 - 6 Exemplarily, the structure of the paper lifting roller limit adjusting mechanism 10 in the present application is shown.

[0061] See Figures 4 - 6 , in the present application, the paper lifting roller limit adjusting mechanism 10 includes a mounting base 1 and a rotating assembly 2. The mounting base 1 is used to connect with the frame 40 of the tipping paper gluing system 100. The rotating assembly 2 includes a connecting shaft 21, a rotating member 23 and a locking member 22. The connecting shaft 21 connects the rotating member 23 and the mounting base 1 to realize the rotatable connection between the rotating member 23 and the mounting base 1, so that the rotating member 23 can rotate relative to the mounting base 1 around the connecting shaft 21. The locking member 22 connects the rotating member 23 and the mounting base 1 to lock the rotating member 23 when the rotating member 23 rotates in place around the connecting shaft 21, so that the rotating member 23 can limit the paper lifting roller 20 rotatably arranged on the frame 40 of the tipping paper gluing system 100 at different angular positions, and realize the adjustment of the rotation stroke of the paper lifting roller 20.

[0062] Based on the above settings, the paper lifting roller limit adjusting mechanism 10 no longer relies on the adjusting screw 1' to adjust the rotation stroke of the paper lifting roller 20, but instead relies on the rotating member 23 that can rotate around the connecting shaft 21 to adjust the rotation stroke of the paper lifting roller 20.

[0063] When adjustment is needed, just loosen the locking member 22, and then the rotating member 23 can be rotated to adjust the rotation stroke of the paper lifting roller 20. Since there is no need to pre-loosen the two components of the fastening screw 2' and the nut 3' as in the related art, the steps are reduced, the operation is simplified, and it is more convenient to use, which can effectively improve the convenience of adjusting the rotation stroke of the paper lifting roller 20.

[0064] Moreover, since the rotation of the rotating member 23 around the connecting shaft 21 does not rely on threads, rotating the rotating member 23 is more labor-saving and easier compared to screwing the adjusting screw 1, which is also beneficial to the convenient use of the paper lifting roller limit adjusting mechanism 10 and improves the convenience of adjusting the rotation stroke of the paper lifting roller 20. At the same time, since the rotation of the rotating member 23 around the connecting shaft 21 does not rely on threads, the rotating member 23 will not have the problem that the thread is stuck by glue like the adjusting screw 1' in the related art, and the adjustment and disassembly of the rotating member 23 are relatively convenient. From this perspective, it is also beneficial to improve the convenience of adjusting the rotation stroke of the paper lifting roller 20.

[0065] Moreover, when the above-mentioned paper-lifting roller limit adjusting mechanism 10 is installed on the machine frame 40, the axial direction of the connecting shaft 21 of the paper-lifting roller limit adjusting mechanism 10 can be parallel to the rotation axis of the paper-lifting roller 20 and substantially perpendicular to the installation surface of the machine frame 40. In this case, the rotation axis of the rotating member 23 and the axis of the locking member 22 are also parallel to the rotation axis of the paper-lifting roller 20 and perpendicular to the installation surface of the machine frame 40, rather than like the adjusting screw 1' in the related art, whose axis is perpendicular to the rotation axis of the paper-lifting roller 20 and parallel to the installation surface of the machine frame 40. Therefore, even when using tools, it is not easy for the tools to interfere with other structural components around the paper-lifting roller limit adjusting mechanism 10, which is more convenient for using tools, especially when it is more convenient to use tools in the case where the position where the paper-lifting roller limit adjusting mechanism 10 is located is relatively narrow. From this perspective, it is also beneficial to improve the convenience of adjusting the rotation stroke of the paper-lifting roller 20.

[0066] It can be seen that the paper-lifting roller limit adjusting mechanism 10 provided by the present application has fewer adjustment steps, is convenient for using tools, and is not easily stuck by glue. Therefore, it can effectively improve the convenience of adjusting the rotation stroke of the paper-lifting roller 20 and improve the efficiency.

[0067] See Figures 4 - 6 , in some embodiments, an arc-shaped groove 28 is provided on the rotating member 23, and a locking hole 14 is provided on the mounting seat 1. The locking member 22 passes through the arc-shaped groove 28 and the locking hole 14 to connect the rotating member 23 and the mounting seat 1.

[0068] The provided arc-shaped groove 28 is adapted to the rotation characteristics of the rotating member 23. It can cooperate with the locking member 22 to restrict the rotation path and rotation range of the rotating member 23, and it is convenient for the locking member 22 to lock the rotating member 23 at any angular position within the rotation range, so that the paper-lifting roller limit adjusting mechanism 10 can stably and reliably adjust the rotation stroke of the paper-lifting roller 20.

[0069] Specifically, continue to refer to Figures 4 - 6 , in some embodiments, the rotating member 23 includes a first rotating portion 24, a second rotating portion 25, and a third rotating portion 26. The second rotating portion 25 is connected between the first rotating portion 24 and the third rotating portion 26 and protrudes at least on one side in a direction intersecting with the sequential connection direction of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26 in a plane perpendicular to the axial direction of the connecting shaft 21. The connecting shaft 21 passes through the first rotating portion 24, and the arc-shaped groove 28 is provided on the second rotating portion 25. At this time, the connecting shaft 21 passes through the first rotating portion 24 of the rotating member 23, the locking member 22 passes through the second rotating portion 25 of the rotating member 23, and the connecting shaft 21 and the locking member 22 are arranged in sequence along the sequential connection direction of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26.

[0070] Since the second rotating part 25 protrudes at least on one side in a direction intersecting the sequential connection direction of the first rotating part 24, the second rotating part 25, and the third rotating part 26 in a plane perpendicular to the axial direction of the connecting shaft 21, and the width of the second rotating part 25 is greater than the widths of the first rotating part 24 and the third rotating part 26, it is more convenient to arrange the arc-shaped groove 28. At this time, the length of the arc-shaped groove 28 can be longer, enabling the rotating member 23 to rotate within a larger range, so that the paper lifting roller limit adjusting mechanism 10 can adjust the rotation stroke of the paper lifting roller 20 within a larger range and more flexibly meet more diverse adjustment requirements.

[0071] More specifically, referring to Figures 4 - 6 , in some embodiments, the edge of the part of the second rotating part 25 that protrudes relative to the first rotating part 24 and the third rotating part 26 is arc-shaped. Structuring the second rotating part 25 as arc-shaped is more convenient for arranging the arc-shaped groove 28 and also more convenient for achieving the smooth rotation of the rotating member 23.

[0072] In the foregoing embodiments, the paper lifting roller limit adjusting mechanism 10 may further include a scale disk 3, and the connecting shaft 21 is also connected to the scale disk 3 to realize the rotatable connection between the rotating member 23 and the scale disk 3, so that the rotating member 23 rotates around the connecting shaft 21 and can be aligned with different scales 31 on the scale disk 3.

[0073] By providing the scale disk 3, during the adjustment process, the rotation angle of the rotating member 23 can be accurately determined, effectively improving the adjustment accuracy, enhancing the convenience of adjusting the rotation stroke of the paper lifting roller 20, and achieving the accurate and rapid adjustment of the rotation stroke of the paper lifting roller 20.

[0074] Among them, in order to further facilitate determining the rotation angle of the rotating member 23, referring to Figures 4 - 6 , in some embodiments, the rotating member 23 is provided with a mark 29 (such as a triangle or an arrow), and the mark 29 is used to indicate the scale 31 on the scale disk 3 that the rotating member 23 is aligned with. In this way, during the adjustment process, just by looking at which scale 31 on the scale disk 3 the mark 29 points to, the rotation angle of the rotating member 23 can be accurately determined, which is more intuitive and convenient.

[0075] In each embodiment where the paper lifting roller limit adjusting mechanism 10 includes a dial 3, the dial 3 and the rotating member 23 can be located on the same side of the mounting base 1, or they can also be located on opposite sides of the mounting base 1. When the dial 3 and the rotating member 23 are located on opposite sides of the mounting base 1, the locking member 22 can be connected only to the rotating member 23 and the mounting base 1, without connecting to the dial 3. In this way, not only is it more convenient to disassemble and assemble the locking member 22, but it is also more convenient to loosen and tighten the locking member 22 during the adjustment process, effectively improving the convenience of adjustment, disassembly, and assembly. And when the dial 3 and the rotating member 23 are located on opposite sides of the mounting base 1, the rotating member 23 and the dial 3 can be respectively arranged on the upper side and the lower side of the mounting base 1, and the dial 3 is used to realize the connection between the paper lifting roller limit adjusting mechanism 10 and the frame 40. In this way, it is both convenient for the rotation of the rotating member 23 and convenient for the installation and fixation of the paper lifting roller limit adjusting mechanism 10 on the frame 40.

[0076] See Figures 4 - 6 , in some embodiments, elongated holes 16 are provided on both the mounting base 1 and the dial 3, and the first connecting member 4 passes through the elongated holes 16 on the mounting base 1 and the dial 3 to connect the dial 3 and the mounting base 1. Among them, it is not difficult to understand that the elongated hole 16 refers to an elongated circular hole, an elongated arc-shaped hole, a U-shaped hole 17, etc., with a length greater than the width. The elongated hole 16 has a long axis and a short axis, and the long axis is longer than the short axis.

[0077] Based on the above settings, the connection between the dial 3 and the mounting base 1 can be conveniently achieved, and it is also beneficial to the convenient installation and fixation of the paper lifting roller limit adjusting mechanism 10 on the frame 40. For example, in some embodiments, the elongated hole 16 can be matched with the mounting hole on the frame 40, so that after the first connecting member 4 passes through the elongated holes 16 on the mounting base 1 and the dial 3, it is inserted into the mounting hole on the frame 40, and the paper lifting roller limit adjusting mechanism 10 can be connected to the frame 40. In this case, since the elongated hole 16 can adapt to mounting holes with different positions, it is beneficial to reduce the precision requirements for the relative position between the paper lifting roller limit adjusting mechanism 10 and the frame 40, and it also enables the paper lifting roller limit adjusting mechanism 10 to meet the installation requirements of different models, effectively expanding the usage range of the paper lifting roller limit adjusting mechanism 10.

[0078] Next, in combination with Figures 4 - 6 the embodiments shown, the paper lifting roller limit adjusting mechanism 10 of the present application will be further described.

[0079] As Figures 4 - 6 shown, in this embodiment, the paper lifting roller limit adjusting mechanism 10 includes a mounting base 1, a rotating assembly 2, a dial 3, a first connecting member 4, and a second connecting member 5, and the rotating assembly 2 includes a connecting shaft 21, a locking member 22, and a rotating member 23.

[0080] Among them, the mounting base 1 is used to provide a mounting foundation for other components of the paper lifting roller limiting and adjusting mechanism 10. As Figure 4 shown, in this embodiment, the mounting base 1 includes a first body 11 and a second body 12. The first body 11 is generally semi-cylindrical, and is provided with a first shaft hole 13 for the connecting shaft 21 to pass through. The first shaft hole 13 is circular and is a threaded hole, which penetrates the first body 11 along the axial direction (also the thickness direction) of the first body 11. The second body 12 is generally cubic, and is connected to the non-arc side of the first body 11, and is provided with a locking hole 14 for the locking member 22 to be inserted, a connecting hole 15 for the second connecting member 5 to pass through, and a long hole 16 for the first connecting member 4 to pass through. The connecting hole 15, the locking hole 14, and the long hole 16 all penetrate the second body 12 along the thickness direction of the second body 12, and the three are arranged in sequence along the length direction of the second body 12, so that the connecting hole 15 and the long hole 16 are located at both ends of the length direction of the second body 12, while the locking hole 14 is located in the middle of the length direction of the second body 12, between the connecting hole 15 and the long hole 16. Specifically, in this embodiment, the long hole 16 is a U-shaped hole 17, and the locking hole 14 and the connecting hole 15 are both circular, and are a threaded hole and a non-threaded smooth hole respectively.

[0081] The rotating member 23 is located on the upper side of the mounting base 1 and is rotatably connected to the mounting base 1 through the connecting shaft 21, and is used to contact the paper lifting roller 20 at different angular positions by rotating around the connecting shaft 21, limit the paper lifting roller 20, and further realize the adjustment of the rotation stroke of the paper lifting roller 20 by the paper lifting roller limiting and adjusting mechanism 10.

[0082] As Figure 4As shown, in this embodiment, the rotating member 23 is generally block-shaped as a whole, and includes a first rotating portion 24, a second rotating portion 25, and a third rotating portion 26. The first rotating portion 24, the second rotating portion 25, and the third rotating portion 26 are sequentially connected along the length direction of the rotating member 23. Moreover, the first rotating portion 24 is generally semi-cylindrical, and is provided with a second shaft hole 27 for the connecting shaft 21 to pass through. The second shaft hole 27 is circular and is a smooth hole, and it penetrates the first rotating portion 24 along the axial direction (also the thickness direction) of the first rotating portion 24. The second rotating portion 25 is in an irregular arc shape, and it protrudes towards one side in the width direction of the rotating member 23 (i.e., the direction intersecting with the sequential connection direction of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26) relative to the first rotating portion 24 and the third rotating portion 26, and is provided with an arc-shaped groove 28 for the locking member 22 to pass through. The inner wall of the arc-shaped groove 28 is smooth and no threads are provided. And, the length of the arc-shaped groove 28 is greater than the diameter of the locking hole 14. In this way, during the rotation of the rotating member 23 around the connecting shaft 21, the arc-shaped groove 28 can always communicate with the locking hole 14, facilitating the locking member 22 to pass through the arc-shaped groove 28 and insert into the locking hole 14 at any position within the rotation range of the rotating member 23 to lock the rotating member 23 and prevent the rotating member 23 from continuing to rotate. The third rotating portion 26 is generally rectangular, and one end thereof away from the first rotating portion 24 is arc-shaped. A mark 29 is provided on the third rotating portion 26. The mark 29 is used to indicate the scale 31 on the dial 3 aligned with the rotating member 23 during the rotation of the rotating member 23. As Figure 4 can be seen, in this embodiment, the mark 29 is provided at one end of the third rotating portion 26 away from the first rotating portion 24, and is a groove in the shape of a triangle (specifically, an isosceles triangle).

[0083] The connecting shaft 21 is used to pass through the rotating member 23 and the mounting base 1 and insert into the dial 3 to connect the rotating member 23, the mounting base 1, and the dial 3, so as to realize the rotation of the rotating member 23 relative to the mounting base 1 and the dial 3. In this embodiment, the connecting shaft 21 is a threaded connector such as a screw. It passes through the second shaft hole 27 on the rotating member 23 and the first shaft hole 13 on the mounting base 1, and inserts into the third shaft hole 32 on the dial 3, and is threadedly connected to the mounting base 1 and the dial 3, and is rotatably connected to the rotating member 23, so that the connecting shaft 21 forms the rotation axis of the rotating member 23, and the rotating member 23 can rotate around the connecting shaft 21 relative to the mounting base 1 and the dial 3.

[0084] The locking member 22 is used to pass through the rotating member 23 and insert into the mounting base 1 to connect the rotating member 23 and the mounting base 1, thereby locking the rotating member 23. In this embodiment, the locking member 22 is a threaded connection member such as a screw. It passes through the arc-shaped groove 28 on the rotating member 23 and inserts into the locking hole 14 on the mounting base 1. The part of its rod body that cooperates with the arc-shaped groove 28 is a smooth rod without threads, while the part of its rod body that cooperates with the locking hole 14 is a threaded rod. In this way, the locking member 22 is threadedly connected to the locking hole 14 and slidably cooperates with the arc-shaped groove 28. After loosening the locking member 22, the rotating member 23 can freely rotate around the connecting shaft 21. After the rotating member 23 rotates to the target angular position, the locking member 22 can be tightened again to prevent the rotating member 23 from continuing to rotate, locking the rotating member 23 at each target angular position.

[0085] The dial 3 is used to mark the rotation angle of the rotating member 23. As Figure 4 shown, in this embodiment, the dial 3 is arranged below the mounting base 1, and it is provided with graduations 31 and a third shaft hole 32. The graduations 31 include graduation lines and also graduation numbers. The third shaft hole 32 is circular and is a threaded hole for the connecting shaft 21 to insert, realizing the threaded connection between the connecting shaft 21 and the dial 3. And, as Figure 4 shown, in this embodiment, the dial 3 is also provided with a connecting hole 15 and an elongated hole 16. The connecting hole 15 and the elongated hole 16 on the dial 3 respectively correspond to the connecting hole 15 and the elongated hole 16 on the mounting base 1, and are used to cooperate with the mounting holes that are threaded holes on the frame 40. Under the action of the first connecting member 4 and the second connecting member 5, the dial 3, the mounting base 1 and the frame 40 are connected to realize the installation and fixation of the paper lifting roller limiting and adjusting mechanism 10 on the frame 40.

[0086] The first connecting member 4 and the second connecting member 5 are used to pass through the mounting base 1 and the dial 3 and insert into the frame 40 to connect the mounting base 1, the dial 3 and the frame 40 together, so as to realize the installation and fixation of the paper lifting roller limiting and adjusting mechanism 10 on the frame 40. In this embodiment, both the first connecting member 4 and the second connecting member 5 are threaded connection members (such as screws). The first connecting member 4 passes through the elongated hole 16 which is a U-shaped hole 17 on the mounting base 1 and the dial 3, and inserts into one mounting hole on the frame 40, and is threadedly connected to the frame 40. The second connecting member 5 passes through the connecting hole 15 on the mounting base 1 and the dial 3, and inserts into another mounting hole on the frame 40, and is threadedly connected to the frame 40. Due to the provision of the elongated hole 16, for different models with different distances between the two mounting holes on the frame 40, the paper lifting roller limiting and adjusting mechanism 10 can also be installed.

[0087] Based on the paper lifting roller limiting and adjusting mechanism 10 of this embodiment, refer to Figure 1, it can be arranged on one or both sides of the rotation direction of the paper lifting roller 20. And when installing the paper lifting roller limit adjusting mechanism 10 of this embodiment on the machine frame 40, the axial direction of the connecting shaft 21 can be parallel to the rotation axis of the paper lifting roller 20, with the rotating member 23 on the upper side and the scale disk 3 on the lower side. Using the first connecting member 4 and the second connecting member 5, the paper lifting roller limit adjusting mechanism 10 is fixed on the machine frame 40.

[0088] During the working process, if it is necessary to adjust the rotation stroke of the paper lifting roller 20, first loosen the locking member 22, and then rotate the rotating member 23 around the connecting shaft 21 to the target angular position (for example, rotate from the Figure 5 shown 0 angular position to the Figure 6 shown 40° angular position), and then tighten the locking member 22 to lock the rotating member 23 at the target angular position, so that the rotating member 23 can contact the paper lifting roller 20 at the target angular position to limit the paper lifting roller 20 and achieve the limitation of the rotation stroke of the paper lifting roller 20. Among them, the rotation of the rotating member 23 does not rely on threads and is not easily stuck due to glue scale. Therefore, even if the glue enters through the arc-shaped groove 28, the rotating member 23 will not have the phenomenon of thread jamming and inability to rotate. Therefore, the adjustment and disassembly are convenient.

[0089] It can be seen that the paper lifting roller limit adjusting mechanism 10 of this embodiment, by changing the adjustment method using an adjusting screw to the adjustment method of the rotating member 23 rotating around a point and adding a scale disk 3, can achieve accurate and rapid adjustment of the rotation stroke of the paper lifting roller 20, and at the same time facilitate the disassembly, maintenance, installation and maintenance of the paper lifting roller limit adjusting mechanism 10. In this way, the effective operation rate can be greatly improved during the production process. Especially for the machines that often change the grades, when changing the tipping paper 50 of different grades, accurate adjustment can be carried out through the scale disk 3, and the adjustment angles can be recorded multiple times, and finally the best adjustment angle can be determined, saving time for future adjustments and shortening the brand change time.

[0090] The above are only exemplary embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
