Cigarettes typically comprise a cigarette section formed from tobacco wrapped with cigarette paper and a filter section formed from a tipping paper wrapped filter element, the tipping paper being affixed to the cigarette paper. It can be seen that tipping paper is an important component of cigarettes, and tipping paper gluing is one of the important procedures for producing cigarettes.

In cigarette making machines, a tipping paper gluing system is typically provided to complete the tipping paper gluing process. The glued tipping paper is continuously conveyed downstream and sheared into the required size for wrapping the filter element.

Fig. 1 exemplarily shows a structure of a tipping paper gluing system.

Referring to fig. 1, the tipping paper gumming system 100 includes a frame 40, a lift roller 20, and a gumming roller 30. Wherein, the paper lifting roller 20 and the glue spreading roller 30 are arranged on the frame 40. The glue applicator 30 is used to transfer glue to the tipping paper 50. The paper lifting roller 20 is rotatably disposed on the frame 40, and guides the tipping paper 50 through the glue spreading roller 30, and lifts or drops the tipping paper 50 by rotating itself, so as to control whether the tipping paper 50 is pressed onto the glue spreading roller 30, and thus control whether glue on the glue spreading roller 30 is coated onto the tipping paper 50.

Typically, the lift roller 20 rotates between a first position and a second position. The rotational displacement of the lift roller 20 between the first position and the second position is referred to as the rotational travel of the lift roller 20. The rotation stroke of the lifting roller 20 influences the compaction degree of the lifting roller 20 on the tipping paper 50, and further influences the gluing amount.

Accordingly, the tipping paper gluing system 100 is also typically provided with a lift roller limit adjustment mechanism 10 to adjust the rotational travel of the lift roller 20. Further, as shown in fig. 1, in general, both sides of the rotation direction of the lift roller 20 are provided with lift roller limit adjustment mechanisms 10 so that the adjustment of the rotation stroke of the lift roller 20 can be achieved by limiting and adjusting the rotation displacement of both sides of the lift roller 20.

In fig. 1, both sides of the rotation direction of the lift roller 20 are provided with lift roller limit adjustment mechanisms 10. The two lift roller limit adjustment mechanisms 10 shown in fig. 1 are all constructed in the related art. The structure of the corresponding lift roller limit adjustment mechanism 10 is further shown in fig. 2 and 3.

Referring to fig. 2 and 3, in the related art, the lift roller limit adjustment mechanism 10 includes an adjustment screw 1', a fastening screw 2', a nut 3', and a base 4'. The adjusting screw 1' is adapted to contact the lift roller 20 to limit the rotational displacement of the lift roller 20, passes through the base 4', and is screw-coupled with the base 4'. The base 4 'is provided with a through hole 5', 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 screw-coupled with the through hole 5' for fastening the adjusting screw 1 '. The nut 3 'is sleeved on the adjusting screw 1' and is used for fastening the adjusting screw 1 'together with the fastening screw 2'.

Returning to fig. 1, when installed, the axial direction of the adjusting screw 1 'is perpendicular to the rotation axis of the lift roller 20, is substantially flush with the surface of the frame 40 (simply referred to as the installation surface) for installing the lift roller limit adjusting mechanism 10, and the fastening screw 2' is located on the side of the adjusting screw 1 'near the installation surface of the frame 40, and the portion of the through hole 5' not penetrated by the fastening screw 2 'is located on the side of the adjusting screw 1' away from the installation surface of the frame 40, that is, the portion of the through hole 5 'not penetrated by the fastening screw 2' and the fastening screw 2 'are located on the upper side and the lower side of the adjusting screw 1', respectively.

In the working process, if the rotation stroke of the lifting roller 20 needs to be adjusted, the fastening screw 2 'and the nut 3' need to be loosened first, then the adjusting screw 1 'needs to be screwed, the length of the adjusting screw 1' extending out of the base 4 'is changed, the adjusting screw 1' can be contacted with the lifting roller 20 at different positions of the rotation direction of the lifting roller 20, the rotation displacement of the lifting roller 20 is limited, and accordingly the rotation stroke of the lifting roller 20 is adjusted.

In practice, it has been found that the lifting roller limit adjusting mechanism 10 in the related art described above has the following problems:

(1) The operation is complicated. As described above, when the rotation stroke of the lift roller 200 needs to be adjusted, the two components of the fastening screw 2 'and the nut 3' need to be loosened first, which requires more steps and more operations.

(2) The tool is inconvenient to use. Since the axial direction of the adjusting screw 1 'is perpendicular to the rotation axis of the lift roller 20 and is substantially flush with the mounting surface of the frame 40, in this case, if the adjusting screw 1' is screwed by using a wrench or a tool such as a hexagon socket, the tool is liable to interfere with other structural parts around the lift roller limit adjusting mechanism 10, and therefore, the tool is inconvenient to use and operate.

(3) The adjustment accuracy is poor. When the rotation stroke of the lifting roller 20 is adjusted, whether the adjusting screw 1' is screwed in place cannot be accurately judged, and multiple adjustments are often needed to meet the requirement, so that the efficiency is affected.

(4) The adjusting screw 1' is easily seized by glue, which makes adjustment and disassembly difficult. As mentioned before, during operation, the through hole 5' is upward and exposes the adjusting screw 1' outside, in this case, the glue thrown out during the gluing process easily enters the through hole 5', and the threads of the adjusting screw 1' are stuck, so that the adjusting screw 1' is blocked and difficult to screw, and the adjusting and the disassembling are difficult.

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

Based on the above findings, the structure of the paper lifting roller limit adjusting mechanism 10 is improved, and the adjusting convenience of the paper lifting roller rotating stroke is improved by providing the paper lifting roller limit adjusting mechanism 10 which is more convenient to use.

Fig. 4 to 6 exemplarily show the structure of the lift roller limit adjustment mechanism 10 in the present application.

Referring to fig. 4-6, in the present application, the lift roller limit adjustment mechanism 10 includes a mount 1 and a rotating assembly 2. The mounting block 1 is adapted to be coupled to a frame 40 of a 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, and realizes rotatable connection of the rotating member 23 and the mounting base 1, so that the rotating member 23 can rotate around the connecting shaft 21 relative to the mounting base 1. The locking piece 22 is connected with the rotating piece 23 and the mounting seat 1, so that when the rotating piece 23 rotates around the connecting shaft 21 to be in place, the rotating piece 23 is locked, and the rotating piece 23 can limit the paper lifting roller 20 of the tipping paper gluing system 100, which is rotatably arranged on the frame 40, at different angle positions, so that the adjustment of the rotating stroke of the paper lifting roller 20 is realized.

Based on the above arrangement, the lift roller limit adjustment mechanism 10 no longer relies on the adjustment screw 1' to achieve adjustment of the rotational travel of the lift roller 20, but instead relies on the rotation member 23 rotatable about the connection shaft 21 to achieve adjustment of the rotational travel of the lift roller 20.

When the adjustment is needed, the locking piece 22 is only needed to be loosened, the rotating piece 23 can be rotated to adjust the rotating stroke of the paper lifting roller 20, and as two parts, namely the fastening screw 2 'and the nut 3', are not needed to be loosened in advance as in the related art, the steps are reduced, the operation is simplified, the use is more convenient, and the adjustment convenience of the rotating stroke of the paper lifting roller 20 can be effectively improved.

In addition, the rotation of the rotating member 23 around the connecting shaft 21 is not dependent on threads, so that compared with the screwing of the adjusting screw 1, the rotating member 23 is more labor-saving and easier, which is also beneficial to the use of the paper lifting roller limit adjusting mechanism 10, and the adjustment convenience of the rotation stroke of the paper lifting roller 20 is improved. Meanwhile, the rotating piece 23 can rotate around the connecting shaft 21 without depending on threads, so that the rotating piece 23 is not stuck and blocked by glue like the adjusting screw 1' in the related art, the adjusting and dismounting of the rotating piece 23 are convenient, and the adjusting convenience of the rotating stroke of the lifting roller 20 is improved from the aspect.

In addition, when the above-mentioned lifting roller limit adjusting mechanism 10 is mounted on the frame 40, the axial direction of the connecting shaft 21 of the lifting roller limit adjusting mechanism 10 can be parallel to the rotation axis of the lifting roller 20 and is approximately perpendicular to the mounting surface of the 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 lifting roller 20 and are perpendicular to the mounting surface of the frame 40, unlike the adjusting screw 1' in the related art, the axis is perpendicular to the rotation axis of the lifting roller 20 and is parallel to the mounting surface of the frame 40, therefore, even if a tool is used, the tool is not easy to interfere with other structural components around the lifting roller limit adjusting mechanism 10, the tool is more convenient to use, especially, the tool is more convenient to use under the condition that the position of the lifting roller limit adjusting mechanism 10 is narrow, and the convenience of adjusting the rotation stroke of the lifting roller 20 is also facilitated from this angle.

Therefore, the paper lifting roller limit adjusting mechanism 10 provided by the application is less in adjusting steps, tools are convenient to use, and the paper lifting roller limit adjusting mechanism is not easy to be bitten by glue, so that the convenience in adjusting the rotating stroke of the paper lifting roller 20 can be effectively improved, and the efficiency is improved.

Referring to fig. 4-6, in some embodiments, the rotating member 23 is provided with an arc-shaped slot 28, the mounting base 1 is provided with a locking hole 14, and the locking member 22 passes through the arc-shaped slot 28 and the locking hole 14 to connect the rotating member 23 and the mounting base 1.

The arc-shaped groove 28 is suitable for the rotation characteristic of the rotating member 23, can be matched with the locking member 22 to restrain the rotation path and the rotation range of the rotating member 23, and is convenient for the locking member 22 to lock the rotating member 23 at any angle position in the rotation range, so that the paper lifting roller limit adjusting mechanism 10 can adjust the rotation stroke of the paper lifting roller 20 stably and reliably.

Specifically, with continued reference to fig. 4 to 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 with respect to the first rotating portion 24 and the third rotating portion 26 in a plane perpendicular to an axial direction of the connecting shaft 21 toward at least one side in a direction intersecting a connecting direction of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26 in order, the connecting shaft 21 passes through the first rotating portion 24, and the arc-shaped groove 28 is provided in the second rotating portion 25. At this time, the connection 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 connection shaft 21 and the locking member 22 are sequentially arranged along the sequential connection direction of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26.

Since the second rotating portion 25 protrudes toward at least one side of the direction intersecting the sequential connection directions of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26 with respect to the first rotating portion 24 and the third rotating portion 26 in a plane perpendicular to the axial direction of the connection shaft 21, the width of the second rotating portion 25 is larger than the widths of the first rotating portion 24 and the third rotating portion 26, and thus, the arrangement of the arc-shaped groove 28 is facilitated, at this time, the length of the arc-shaped groove 28 can be longer, so that the rotating member 23 can be rotated in a larger range, and thus, the lift roller limit adjusting mechanism 10 can realize adjustment of the rotation stroke of the lift roller 20 in a larger range, and more flexibly meet more diverse adjustment demands.

More specifically, referring to fig. 4-6, in some embodiments, the edges of the portions of the second rotating portion 25 that protrude with respect to the first rotating portion 24 and the third rotating portion 26 are arcuate. The second rotating portion 25 is constructed in an arc shape, which is more convenient for the arrangement of the arc-shaped groove 28 and for the smooth rotation of the rotating member 23.

In the foregoing embodiments, the lift roller limit adjustment mechanism 10 may further include a dial 3, and the connecting shaft 21 is further connected to the dial 3, so as to implement rotatable connection of the rotating member 23 and the dial 3, so that the rotating member 23 rotates around the connecting shaft 21 and can be aligned with different scales 31 on the dial 3.

Through setting up calibrated scale 3 for in the adjustment process, can accurately confirm the rotation angle of rotating member 23, effectively improve and adjust the accuracy, promote the regulation convenience to lifting roller 20 rotation stroke, realize lifting roller 20 rotation stroke's accurate quick adjustment.

Therein, for further convenience in determining the rotation angle of the rotation member 23, see fig. 4-6, in some embodiments, a logo 29 (e.g. triangle or arrow) is provided on the rotation member 23, the logo 29 being used to indicate the scale 31 on the scale 3 to which the rotation member 23 is aligned. In this way, in the adjusting process, only the marks 29 need to be seen to point to which scale 31 on the dial 3, so that the rotating angle of the rotating member 23 can be accurately determined, and the adjusting device is more visual and convenient.

In embodiments in which the lift roller limit adjustment mechanism 10 includes the dial 3, the dial 3 and the rotary member 23 may be located on the same side of the mount 1, or may be located on opposite sides of the mount 1. When the calibrated scale 3 and the rotating piece 23 are positioned on two opposite sides of the mounting seat 1, the locking piece 22 can be only connected with the rotating piece 23 and the mounting seat 1, but not connected with the calibrated scale 3, so that the locking piece 22 is more convenient to assemble and disassemble, and the locking piece 22 is more convenient to loosen and tighten in the adjusting process, and the adjusting and assembling and disassembling convenience is effectively improved. Moreover, when the dial 3 and the rotating member 23 are located on two opposite sides of the mounting seat 1, the rotating member 23 and the dial 3 can be respectively arranged on the upper side and the lower side of the mounting seat 1, and the dial 3 is utilized to realize connection of the paper lifting roller limit adjusting mechanism 10 and the frame 40, so that the rotation of the rotating member 23 is facilitated, and the installation and the fixation of the paper lifting roller limit adjusting mechanism 10 on the frame 40 are also facilitated.

Referring to fig. 4-6, in some embodiments, the mount 1 and the dial 3 are each provided with an elongated hole 16, and the first connector 4 passes through the elongated holes 16 of the mount 1 and the dial 3 to connect the dial 3 and the mount 1. It is to be understood that the elongated hole 16 is a hole having a length larger than the width, such as an oblong hole, an elongated arc hole, or a U-shaped hole 17. The elongated aperture 16 has a major axis and a minor axis, with the major axis being longer than the minor axis.

Based on the above arrangement, the dial 3 and the mounting base 1 can be conveniently connected, and the roller lifting limiting and adjusting mechanism 10 is also convenient to mount and fix on the frame 40. For example, in some embodiments, the elongated hole 16 may be matched with a mounting hole on the frame 40, so that after the first connecting piece 4 passes through the mounting seat 1 and the elongated hole 16 on the dial 3, it is inserted into the mounting hole on the frame 40, and the lifting roller limit adjusting mechanism 10 may be connected to the frame 40, in this case, since the elongated hole 16 may adapt to the mounting holes with different positions, it is beneficial to reduce the accuracy requirement on the relative position between the lifting roller limit adjusting mechanism 10 and the frame 40, and in addition, the lifting roller limit adjusting mechanism 10 may meet the mounting requirement of different models, so as to effectively enlarge the application range of the lifting roller limit adjusting mechanism 10.

The lift roller limit adjustment mechanism 10 of the present application will be further described with reference to the embodiments shown in fig. 4 to 6.

Wherein, mount pad 1 is used for providing the installation basis for lifting other parts of the spacing adjustment mechanism of paper roll 10. As shown in fig. 4, in this embodiment, the mount 1 includes a first housing 11 and a second housing 12. The first housing 11 is substantially semi-cylindrical and is provided with a first shaft hole 13 for passing the connection shaft 21 therethrough. The first shaft hole 13 is circular and is a screw hole that penetrates the first housing 11 in the axial direction (also the thickness direction) of the first housing 11. The second housing 12 has a substantially cubic shape, is connected to the non-arc-shaped side of the first housing 11, and is provided with a locking hole 14 for inserting the locking member 22, a connecting hole 15 for passing the second connecting member 5, and an elongated hole 16 for passing the first connecting member 4. The connecting hole 15, the locking hole 14 and the elongated hole 16 penetrate through the second seat body 12 along the thickness direction of the second seat body 12, and the connecting hole 15, the locking hole 14 and the elongated hole 16 are sequentially arranged along the length direction of the second seat body 12, so that the connecting hole 15 and the elongated hole 16 are positioned at two ends of the second seat body 12 in the length direction, and the locking hole 14 is positioned at the middle of the second seat body 12 in the length direction and is positioned between the connecting hole 15 and the elongated hole 16. Specifically, in this embodiment, the elongated hole 16 is a U-shaped hole 17, and the locking hole 14 and the connecting hole 15 are circular, and are a threaded hole and an unthreaded light hole, respectively.

The rotating piece 23 is located on the upper side of the mounting seat 1 and is rotatably connected to the mounting seat 1 through the connecting shaft 21, and is used for contacting with the lifting roller 20 at different angle positions through rotating around the connecting shaft 21 to limit the lifting roller 20, so that the lifting roller limit adjusting mechanism 10 can adjust the rotating stroke of the lifting roller 20.

And, the first rotating portion 24 is substantially semi-cylindrical, and is provided with a second shaft hole 27 for passing the connection shaft 21 therethrough. The second shaft hole 27 is circular and is a light hole, and penetrates the first rotating portion 24 in the axial direction (also the thickness direction) of the first rotating portion 24. The second rotating portion 25 is irregularly curved, protrudes toward one side of the width direction of the rotating member 23 (i.e., the direction intersecting the sequential connection direction of the first rotating portion 24, the second rotating portion 25, and the third rotating portion 26) with respect to the first rotating portion 24 and the third rotating portion 26, and is provided with an arc-shaped groove 28 through which the locking member 22 passes. The inner wall of the arcuate slot 28 is smooth and is not threaded. And, the length of the arc-shaped groove 28 is greater than the diameter of the locking hole 14, so that the arc-shaped groove 28 can be always communicated with the locking hole 14 in the process of rotating the rotating piece 23 around the connecting shaft 21, the locking piece 22 can conveniently penetrate through the arc-shaped groove 28 at any position in the rotating range of the rotating piece 23 and is inserted into the locking hole 14, the rotating piece 23 is locked, and the rotating piece 23 is prevented from continuing to rotate. The third rotating portion 26 is substantially rectangular, and an end thereof remote from the first rotating portion 24 is arc-shaped. The third rotating portion 26 is provided with a logo 29. The index 29 is used to indicate the scale 31 on the scale 3 with which the rotator 23 is aligned during rotation of the rotator 23. As can be seen from fig. 4, in this embodiment, the mark 29 is disposed at an end of the third rotating portion 26 away from the first rotating portion 24, and is a triangular (specifically, isosceles triangle) groove.
