[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without carrying out creative work are within the scope of protection of this application.

[0058] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0059] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0060] In the description of the present application, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present application.

[0061] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0062] During the cigarette production process, arranged cigarettes usually need to be packaged in sequence with aluminum paper, inner frame paper, trademark paper and transparent paper to form cigarette packs.

[0063] Therefore, the inner frame paper is an important component of the cigarette pack, which is also called cardboard and plays the role of supporting the internal frame of the cigarette pack.

[0064] In order to realize the automatic conveying of inner frame paper, a supply system is usually provided in cigarette packaging machines such as the GDX2 hard box packaging machine. The corresponding supply system is mainly used to cut the inner frame paper into single sheets and convey it to the packaging position. During operation, the rolled inner frame paper is unrolled under the action of the unwinding mechanism, and then passes through the paper guide roller and the guide plates on both sides, and then flows to the downstream scoring roller with the cutting device to enter the scoring and cutting process.

[0065] The two side guide plates are located between the paper roll holder and the scoring roller in the conveying direction and are arranged opposite to each other on both sides of the conveying path of the inner frame paper, and mainly play a conveying guide role. Of the two guide plates, the one located on the outside of the conveying path is usually called the outer guide plate, and the one located on the inside of the conveying path is usually called the inner guide plate. The scoring roller is used to carve folding lines on the inner frame paper to facilitate folding the inner frame paper in the subsequent packaging process. The cutting device is located downstream of the scoring roller and is used to cut the inner frame paper into single sheets of inner frame paper that meet the length requirements.

[0066] In practice, it is found that the inner frame paper is unstable when being transported to the scoring roller, which is not only not conducive to the smooth progress of subsequent processes, affecting the packaging effect and efficiency, but also increases the waste of auxiliary materials to a certain extent. It is mainly manifested in the following two aspects:

[0067] (1) After unfolding, the inner frame paper still has a certain degree of curling, and the conveying smoothness is poor. It is easy to be blocked and piled up, and paper squeezing occurs at the notched roller, etc., which will cause the downstream suction arm to fail to suck the inner frame paper, causing the "No. 4 wheel has no inner frame paper" fault, resulting in equipment shutdown and affecting efficiency;

[0068] (2) The inner frame paper is conveyed intermittently. During the intermittent conveying process, the inner frame paper will vibrate left and right (i.e., in the lateral direction of the conveying direction), which affects the recognition of the centering mark by the centering mark detector, resulting in frequent "centering mark error" failures, an increase in the number of unqualified inner frame paper packaging products, and an increase in the number of unqualified cigarette packs rejected at the exit of the eighth wheel, resulting in a waste of auxiliary materials. In addition, three consecutive "centering mark errors" will cause the equipment to shut down, affecting efficiency.

[0069] Among them, the centering mark is a mark set on the inner frame paper and used to identify the pattern on the inner frame paper.

[0070] Some inner frame papers, such as medium and thin inner frame papers, carry patterns such as QR codes. This kind of inner frame paper with patterns needs to be positioned during transportation and cutting in order to ensure that the pattern is accurately positioned in the cigarette pack. For this reason, the inner frame paper with patterns is usually printed with a centering mark. The centering mark is generally a dark (e.g., black) color block, which is located on the opposite side of the pattern and corresponds to the pattern one by one, so that the pattern positioning function can be achieved by identifying the centering mark.

[0071] During the transportation process of the inner frame paper supply system, the side of the inner frame paper with the centering mark is usually located on the outside, that is, usually close to the outer guide plate. In addition, in order to realize the automatic recognition of the centering mark, a centering mark detector is usually provided in the inner frame paper supply system. The corresponding centering mark detector is generally set at a position in front of the inner and outer guide plates, and the pattern positioning is realized by recognizing the centering mark within a certain period. If the centering mark detector fails to detect the centering mark within the set period, it will issue a "centering mark error" alarm and reject the unqualified products. If there are three consecutive "centering mark errors", the machine will be shut down.

[0072] The detection result of the centering mark detector affects the accuracy of the position of the pattern on the inner frame paper in the cigarette pack. If the recognition is inaccurate, the position of the pattern on the inner frame paper in the cigarette pack may deviate, affecting the wrapping effect of the inner frame paper, resulting in an increase in defective products, resulting in waste and increased costs.

[0073] In addition, the detection result of the centering mark detector will be used as the basis for the inner frame paper conveying distance each time, that is, the distance of each advance during the inner frame paper conveying process will be determined based on the recognition result. If the recognition is inaccurate, the conveying distance may be too large or too small, resulting in too much or too little single conveying length, which will further aggravate the paper squeezing phenomenon at the notch roller and reduce efficiency.

[0074] During the transportation process, the left and right shaking of the inner frame paper is not conducive to the accurate identification of the centering mark by the centering mark detector, which will cause the frequent occurrence of "centering mark error" failures, which will not only increase the number of defective products and cause waste, but also may cause equipment shutdown and affect efficiency.

[0075] It can be seen that there is a problem of unstable conveying during the conveying of the inner frame paper to the scoring roller, which is not only not conducive to the smooth progress of subsequent processes, affecting the packaging effect and packaging efficiency, but also increases the waste of auxiliary materials and increases costs to a certain extent.

[0076] In view of the above situation, the present application provides an inner frame paper guiding device, an inner frame paper guiding assembly, an inner frame paper supply system and a cigarette packaging machine to improve the conveying stability of the inner frame paper.

[0077] Figure 1-Figure 9 The structures of the inner frame paper supply system, the inner frame paper guide assembly and the inner frame paper guide device in the present application are exemplarily shown.

[0078] in, Figure 1 The structures of the inner frame paper supply system and the inner frame paper guide assembly are exemplarily shown.

[0079] See also Figure 1 In the present application, the inner frame paper supply system 100 includes a scoring roller and an inner frame paper guide assembly 101.

[0080] The scoring roller is located at Figure 1 The corresponding scoring roller is used to score folding lines on the inner frame paper to facilitate folding the inner frame paper at the folding lines during subsequent packaging.

[0081] The inner frame paper guide assembly 101 is arranged along the conveying direction of the inner frame paper (such as Figure 1 The inner frame paper is transported from the paper reel to the scoring roller. Figure 1 The inner frame paper guide assembly 101 includes an inner frame paper guide device 10 and a fixed seat 6. The inner frame paper guide device 10 is arranged on the fixed seat 6 and is located on one side of the conveying path of the inner frame paper to the scoring roller, and is used to guide the inner frame paper during the conveying process of the inner frame paper to the scoring roller.

[0082] The number of the inner frame paper guide devices 10 may be two. In this case, the inner frame paper guide assembly 101 includes two inner frame paper guide devices 10, which are located on opposite sides of the inner frame paper conveying path. That is, an inner frame paper guide device 10 is provided on opposite sides of the inner frame paper conveying path. At this time, the two inner frame paper guide devices 10 can also replace the inner and outer guide plates in the related art to guide the inner frame paper conveyed to the scoring roller on both sides; or, see Figure 1 , the number of the inner frame paper guide device 10 can also be one. In this case, the inner frame paper guide assembly 101 includes only one inner frame paper guide device 10, and the inner frame paper guide device 10 is located on one side of the inner frame paper conveying path. In other words, the inner frame paper guide device 10 is only provided on one side of the inner frame paper conveying path, and the inner frame paper guide device 10 is not provided on the other side. At this time, the inner frame paper guide device 10 can be located on the inner side of the inner frame paper conveying path, replacing the inner guide plate in the related art, and guiding the inner frame paper conveyed to the scoring roller on the inner side, or it can also be located on the outer side of the inner frame paper conveying path, replacing the outer guide plate in the related art, and guiding the inner frame paper conveyed to the scoring roller on the outer side. Among them, since the centering mark is usually located on the outside, therefore, when the inner frame paper guide device 10 is located on the outside, the inner frame paper guide device 10 and the centering mark are located on the same side, which is more conducive to improving the conveying stability by improving the recognition accuracy of the centering mark, which will be further explained later.

[0083] In the case where the inner frame paper guide assembly 101 includes only one inner frame paper guide device 10, in order to guide both sides of the inner frame paper, see Figure 1In some embodiments, the inner frame paper guide assembly 101 further includes a second guide plate 4, and the second guide plate 4 and the inner frame paper guide device 10 are arranged on opposite sides of the inner frame paper conveying path. For example, when the inner frame paper guide device 10 is located on the outside, the second guide plate 4 is located on the inside and acts as an inner guide plate. For another example, when the inner frame paper guide device 10 is located on the inside, the second guide plate 4 is located on the outside and acts as an outer guide plate. In this way, the inner frame paper can be better conveyed and guided.

[0084] Figure 2-Figure 8 The structure of the inner frame paper guide device 10 is further shown.

[0085] See also Figure 2-Figure 8 , and combined with Figure 1 It can be seen that in the present application, the inner frame paper guiding device 10 includes a first guide plate 1 and a rolling device 2. The first guide plate 1 is used to be installed on the fixed seat 6 and is located on one side of the conveying path of the inner frame paper to the scoring roller to guide the inner frame paper conveyed to the scoring roller. The rolling device 2 includes a rolling member 21 and a support shaft 22, and the rolling member 21 is rotatably arranged on the first guide plate 1 through the support shaft 22 to roll the inner frame paper.

[0086] The inner frame paper guiding device 10 provided by the above scheme is improved on the basis of the guide plate in the related art.

[0087] Among them, the first guide plate 1 is the same as the inner and outer guide plates in the related art, and is located on one side of the conveying path of the inner frame paper to the scoring roller, and guides the inner frame paper conveyed to the scoring roller. However, the inner and outer guide plates in the related art are not provided with a rolling device 2, and the inner frame paper has a large curling property. The above scheme further provides a rolling device 2 on the first guide plate 1, and uses the rolling member 21 of the rolling device 2 to roll the inner frame paper conveyed to the scoring roller, which can effectively reduce the curling property of the inner frame paper, improve the flatness of the inner frame paper before entering the scoring roller, improve the conveying stability of the inner frame paper, reduce the risk of conveying blockage, and reduce the accumulation of the inner frame paper, which is conducive to solving the problem of paper squeezing at the scoring roller, etc., and preventing the inner frame paper from being missing due to paper squeezing, resulting in equipment shutdown, and therefore, is conducive to improving packaging efficiency.

[0088] In addition, the rolling member 21 is pressed on the inner frame paper, which can limit the inner frame paper and reduce the left and right shaking of the inner frame paper. Therefore, it can effectively solve the problem of poor inner frame paper conveying stability caused by the left and right shaking of the inner frame paper, improve the conveying stability of the inner frame paper, and improve the recognition accuracy of the centering mark. In particular, when the inner frame paper guiding device 10 is arranged on the side of the inner frame paper with the centering mark, the rolling member 21 can roll the side of the inner frame paper with the centering mark to better prevent the centering mark from moving. Therefore, it can more effectively improve the recognition accuracy of the centering mark, thereby reducing the probability of defective products and shutdowns due to inaccurate recognition of the centering mark, improving the packaging effect of the inner frame paper, improving the packaging efficiency of the inner frame paper, reducing the amount of waste, saving auxiliary material consumption, and reducing costs.

[0089] Among them, saving auxiliary material consumption is particularly important for medium and thin cigarettes. Because, compared with conventional cigarettes, the overall size of the cigarette pack of medium and thin cigarettes is smaller, including the size of small box trademark paper, lining paper, inner frame paper and cigarette box and other tobacco materials are also smaller, which also makes the absolute value of the position deviation of auxiliary materials in the production process smaller. Therefore, in order to ensure product quality, the single box consumption of auxiliary materials for medium and thin cigarettes is relatively higher than that of auxiliary materials for conventional cigarettes in the entire production process, and it is even more necessary to reduce the consumption of auxiliary materials. In this sense, the inner frame paper guiding device 10 of the present application is particularly suitable for guiding the inner frame paper (called medium and thin inner frame paper) used for medium and thin cigarettes. In other words, the inner frame paper supply system 100 of the present application can be particularly a medium and thin inner frame paper supply system.

[0090] It can be seen that the above scheme, by arranging a rolling device 2 having a rolling part 21 capable of rolling the inner frame paper on the first guide plate 1 located on one side of the conveying path of the inner frame paper to the scoring roller, can effectively solve the problem of poor inner frame paper conveying stability caused by the large curling of the inner frame paper and the left and right shaking of the inner frame paper. By improving the flatness of the inner frame paper before it enters the scoring roller and reducing the left and right shaking of the inner frame paper during the conveying process, the conveying stability of the inner frame paper is improved, the risk of paper squeezing and inaccurate recognition of the centering mark is reduced, thereby improving the packaging effect and packaging efficiency of the inner frame paper, reducing the amount of waste, saving auxiliary material consumption, reducing costs, and realizing an efficient, high-quality and low-cost inner frame paper supply and packaging process.

[0091] The number of the rolling devices 2 in the inner frame paper guide device 10 is not limited and can be one, two or more. When the inner frame paper guide device 10 includes at least two rolling devices 2, see Figure 2The at least two rolling devices 2 can be arranged at intervals along the length direction of the first guide plate 1 (which is also the conveying direction of the inner frame paper). In this way, the at least two rolling devices 2 can roll and limit the inner frame paper at at least two positions in the conveying direction, more effectively improve the flatness of the inner frame paper, and more reliably reduce the left and right shaking of the inner frame paper. Therefore, the conveying stability of the inner frame paper can be more effectively improved, and the probability of paper squeezing and inaccurate recognition of the centering mark can be more reliably reduced, thereby achieving a more efficient, high-quality and low-cost inner frame paper supply and packaging process.

[0092] It can be seen that by arranging at least two rolling devices 2 spaced apart along the length direction on the first guide plate 1, the conveying stability of the inner frame paper can be further improved.

[0093] It can be understood that in order to realize the rolling effect of the rolling member 21 of the rolling device 2 on the inner frame paper, the rolling member 21 of the aforementioned embodiments needs to be in contact with the inner frame paper.

[0094] In order to achieve the contact between the rolling member 21 and the inner frame paper, the rolling member 21 can be arranged at the edge of the first guide plate 1 (for example, the edge in the length direction), so that the rolling member 21 is not blocked by the first guide plate 1, contacts the inner frame paper, and rolls the inner frame paper; or, as an alternative, see Figure 2 and Figure 3 A through hole 14 may also be provided on the first guide plate 1, and the rolling member 21 may be located at the through hole 14, so that the rolling member 21 may pass through the through hole 14, contact the inner frame paper, and roll the inner frame paper.

[0095] Among them, by setting a through hole 14 on the first guide plate 1, when the rolling member 21 contacts the inner frame paper, the structure of the inner frame paper guide device 10 is more compact, and the first guide plate 1 is lighter, and the material consumption in making the first guide plate 1 is less and the cost is lower. Therefore, it is beneficial to improve the conveying stability of the inner frame paper based on a more compact structure and lower cost.

[0096] In the case where the inner frame paper guide device 10 includes at least two rolling devices 2, in order to allow the rolling members 21 of the at least two rolling devices 2 to contact the inner frame paper through the through hole 14, a larger through hole 14 can be provided on the first guide plate 1, and the rolling members 21 of the at least two rolling devices 2 are all located at the larger through hole 14. In this case, all the rolling members 21 contact the inner frame paper through the same through hole 14; or, as an alternative, see Figure 2 and Figure 3At least two through holes 14 can also be set on the first guide plate 1, and the at least two through holes 14 can correspond one by one to the at least two rolling devices 2 of the inner frame paper guide device 10. In this case, the rolling member 21 of each rolling device 2 is no longer located at the same through hole 14, but is located at different through holes 14. Each rolling member 21 contacts the inner frame paper through its corresponding through hole 14. At this time, different rolling members 21 are less likely to affect each other, and each through hole 14 can also play a certain limiting role on its corresponding rolling member 21, so the structural stability is stronger and the rolling effect is better.

[0097] In the aforementioned embodiments, the rolling member 21 of the rolling device 2 is connected to the first guide plate 1 through the support shaft 22. The support shaft 22 can be directly connected to the first guide plate 1, or a support seat 3 can be provided in the inner frame paper guide device 10 so that the support shaft 22 is connected to the first guide plate 1 through the support seat 3.

[0098] By setting up the support seat 3, it is more convenient to connect the support shaft 22 with the first guide plate 1. In particular, it is more convenient to connect the support shaft 22 of at least two rolling devices 2 with the first guide plate 1, so that different rolling devices 2 can be supported by the same support seat 3 above the first guide plate 1. In this way, not only is the structure simpler and more compact, but also different rolling devices 2 can be supported more stably.

[0099] In addition, when the support base 3 is provided, more diverse functions can be realized by designing the support base 3.

[0100] For example, in some embodiments, the support seat 3 is constructed so that the position of the rolling device 2 in the height direction of the first guide plate 1 (also in the up and down direction of the whole machine) can be adjusted. In this way, the conveying stability of the inner frame paper can be more effectively improved, and it is easy to take into account both the conveying stability and replacement convenience of the inner frame paper.

[0101] Because, when the support seat 3 makes the position of the rolling device 2 in the height direction of the first guide plate 1 adjustable, the rolling device 2 can flexibly adjust its own height position during the normal conveying of the inner frame paper, so that the rolling member 21 always maintains good contact with the inner frame paper and effectively rolls, thereby helping to further improve the conveying stability of the inner frame paper.

[0102] In addition, as mentioned above, during the normal conveying process of the inner frame paper, the rolling member 21 needs to contact the inner frame paper, so in this case, the height position of the rolling device 2 is relatively low. During the packaging process, if a roll of inner frame paper is used up, it is necessary to replace it with a new inner frame paper and splice the new and old inner frame paper. In the corresponding process, the new inner frame paper needs to pass through the space under the first guide plate 1. Therefore, in this case, it is hoped that the rolling device 2 is raised so that the new paper can pass smoothly.

[0103] It can be seen that the height position of the rolling device 2 required for the normal conveying process and the replacement process of the inner frame paper is different. The support seat 3 is constructed so that the position of the rolling device 2 in the height direction of the first guide plate 1 is adjustable, which can facilitate the rolling device 2 to flexibly adjust its own height position to meet the different needs of the normal conveying process and the replacement process of the inner frame paper. On the one hand, during the normal conveying process, the rolling device 2 can be at a lower height position, and the rolling member 21 contacts the inner frame paper to roll and improve the conveying stability of the inner frame paper. On the other hand, during the replacement process, the rolling device 2 can be adjusted to a higher height position to reserve sufficient space for the new paper to pass through, which is convenient for the smooth replacement of the inner frame paper.

[0104] It can be seen that constructing the support seat 3 to make the position of the rolling device 2 in the height direction of the first guide plate 1 adjustable can not only more effectively improve the conveying stability of the inner frame paper, but also effectively take into account the conveying stability and replacement convenience of the inner frame paper, so that the conveying stability of the inner frame paper can be improved by using the rolling device 2 without affecting the replacement convenience of the inner frame paper, or in other words, the conveying stability of the inner frame paper can be improved without affecting the replacement convenience of the inner frame paper.

[0105] As an example of a support seat 3, see Figure 2 The support seat 3 includes a first support plate 31 and a second support plate 32. The first support plate 31 is connected to the first guide plate 1 and is connected to the support shaft 22 through the second support plate 32. In this case, in order to realize the height adjustment function of the support seat 3 on the rolling device 2, in some embodiments, the thickness of the second support plate 32 is 0.1-1 mm. At this time, the thickness of the second support plate 32 is relatively thin and has a certain elasticity, so that the position of the rolling device 2 in the height direction of the first guide plate 1 can be adjusted.

[0106] Of course, in addition to making the second support plate 32 thinner to make the second support plate 32 elastic, the second support plate 32 can also be made of an elastic material to make the second support plate 32 elastic, thereby making the position of the rolling device 2 in the height direction of the first guide plate 1 adjustable.

[0107] Also, see Figure 2 as well as Figure 4-Figure 5 In some embodiments, a notch 33 is provided on the support seat 3, and the rolling member 21 is at least partially located in the notch 33. In this way, the connection between the rolling device 2 and the support seat 3 is more convenient, and the structure is more compact.

[0108] Further, see Figure 2 and Figure 5In the embodiment where the inner frame paper guide device 10 includes at least two rolling devices 2, at least two notches 33 may be provided on the support seat 3, and the at least two notches 33 correspond to the rolling members 21 of the at least two rolling devices 2 of the inner frame paper guide device 10. In this way, each rolling member 21 corresponds to a notch 33, which makes the connection more convenient and the structure more compact.

[0109] It is understood that in the present application, the shape of the notch 33 can be varied. For example, see Figure 2 and Figure 5 The notch 33 is U-shaped, which is more suitable for accommodating the rotatable circular rolling element 21.

[0110] In the above embodiments, the rolling element 21 can have various structural forms. Figure 6 In some embodiments, the rolling member 21 includes a bearing 24. Since the bearing 24 has a reliable structure and is flexible in rotation, when the rolling member 21 includes the bearing 24, a better rolling effect can be achieved, and the conveying stability of the inner frame paper can be more effectively improved.

[0111] In addition, as a further improvement of the above-mentioned embodiments, the rolling device 2 includes not only a rolling member 21 and a support shaft 22, but also a stopper 23, which is arranged on the support shaft 22 and located axially outside the rolling member 21 to axially limit the rolling member 21. In this way, the rolling member 21 is not easily displaced axially and can be more stably arranged on the support shaft 22, so that the structural reliability is higher and the rolling effect is better.

[0112] The limiting member 23 may adopt various structural forms. Figure 2 as well as Figure 6-Figure 8 In some embodiments, the limiting member 23 includes a clamping spring 25. In this case, a clamping groove 26 is provided on the support shaft 22, and the clamping spring 25 is clamped in the clamping groove 26 and clamped with the support shaft 22. The clamping spring 25 is used to axially limit the rolling member 21, which has a simple structure and a good limiting effect. Of course, when the limiting member 23 adopts other structural forms, a clamping groove 26 can also be provided on the support shaft 22, so that the limiting member 23 is clamped in the clamping groove 26, thereby enhancing the setting reliability of the limiting member 23.

[0113] In addition, the number of the limiting members 23 in the rolling device 2 is not limited, and can be one, two, or more. For example, in some embodiments, the rolling device 2 includes two limiting members 23, and the two limiting members 23 are arranged on both sides of the axial direction of the rolling member 21, so that the limiting of both sides of the axial direction of the rolling member 21 can be achieved, and the rolling member 21 can be reliably prevented from moving to any side of the axial direction. Therefore, it is more conducive to improving the setting stability of the rolling member 21, thereby better rolling, and further improving the conveying stability of the inner frame paper.

[0114] As an example of the first guide plate 1 in the aforementioned embodiments, see Figure 2 as well as Figure 3 The first guide plate 1 includes a first plate segment 11 and a second plate segment 12 connected to each other. The first plate segment 11 is provided with a first opening 13, and the first opening 13 is used to avoid the cutter 103, so that the cutter 103 cuts the inner frame paper at the first opening 13. The second plate segment 12 is located upstream of the first plate segment 11 along the conveying direction of the inner frame paper, and the rolling device 2 is arranged on the second plate segment 12.

[0115] The cutter 103 is not the cutter of the cutting device mentioned above for cutting the inner frame paper into individual sheets, but another cutter. Figure 1 The cutter 103 is arranged upstream of the scoring roller and is mainly used to cut off the inner frame paper to be replaced so as to splice the new and old inner frame papers.

[0116] The first guide plate 1 comprises a first plate section 11 having a first opening 13 for avoiding the cutter 103, so that the cutter 103 can smoothly cut the old inner frame paper.

[0117] In fact, the inner and outer guide plates in the related art are provided with a first opening 13 for avoiding the cutter 103 . However, the inner and outer guide plates in the related art are not provided with a rolling device 2 .

[0118] In the above scheme, the first guide plate 1 not only includes a first plate segment 11 having a first opening 13 for avoiding the cutter 103, but also includes a second plate segment 12 connected upstream of the first plate segment 11, and a rolling device 2 is arranged on the second plate segment 12, so that the rolling device 2 is located upstream of the cutter 103, which can effectively improve the conveying stability of the inner frame paper without affecting the old paper cutting function.

[0119] In addition, the inner and outer guide plates in the related art are both short, generally less than 20 mm. In this case, the guiding distance is short, the guiding effect is poor, and it is not convenient to set the rolling device 2. In view of this, in some embodiments, the first guide plate 1 is extended and the length becomes 20-100 mm. In this way, not only the guiding distance is longer and the guiding effect is better, but also the setting of the rolling device 2 is more convenient, especially, it is more convenient to set two or more rolling devices 2, which is conducive to better improving the conveying stability of the inner frame paper.

[0120] In addition, see Figure 2 and Figure 3 In some embodiments, an observation window 15 is provided on the first guide plate 1 to observe the inner frame paper. In this way, it is more convenient to observe the state of the inner frame paper, and at the same time, the weight of the first guide plate 1 can be further reduced, the material consumption of the first guide plate 1 can be reduced, and the cost can be saved.

[0121] As mentioned above, when the inner frame paper guiding assembly 101 includes only one inner frame paper guiding device 10 , in order to guide the inner frame paper on both sides, in some embodiments, the inner frame paper guiding assembly 101 further includes a second guide plate 4 . Fig. 9 That is, the structure of the second guide plate 4 is shown as an example.

[0122] See also Fig. 9 , and combined with Figure 1 It can be seen that in some embodiments, the second guide plate 4 includes a third plate segment 41 and a fourth plate segment 42 connected to each other, and a second opening 43 is provided on the third plate segment 41. The second opening 43 is used to avoid the cutter 103, so that the cutter 103 cuts the inner frame paper at the second opening 43. The fourth plate segment 42 is located upstream of the third plate segment 41 along the conveying direction of the inner frame paper. The third plate segment 41 and the fourth plate segment 42 are respectively opposite to the first plate segment 11 and the second plate segment 12 of the first guide plate 1. In this way, the second guide plate 4 is equal in length to the first guide plate 1 having the first plate segment 11 and the second plate segment 12, and has a substantially similar structure. The two are symmetrically arranged on both sides of the inner frame paper, which can better guide the inner frame paper for conveying. In particular, the two are equal in length, and can guide the inner frame paper of equal length, so that the guiding effect is better.

[0123] Also, see Fig. 9 , and combined with Figure 1 In some embodiments, the second guide plate 4 is provided with an observation port 44 for observing the inner frame paper. In this way, it is more convenient to observe the state of the inner frame paper, and at the same time, the weight of the second guide plate 4 can be further reduced, the material consumption of the second guide plate 4 can be reduced, and the cost can be saved.

[0124] Next, Figure 1-Figure 9 The illustrated embodiment is further described.

[0125] like Figure 1-Figure 9 As shown, in this embodiment, the inner frame paper supply system 100 is a medium and thin cigarette inner frame paper supply system, which includes a scoring roller (not shown, located at Figure 1 The inner frame paper guide assembly 101 is located in the middle box 102 and is located upstream of the scoring roller.

[0126] The inner frame paper guide assembly 101 includes a fixed seat 6, an inner frame paper guide device 10 and a second guide plate 4 arranged on the fixed seat 6. The inner frame paper guide device 10 is located on the outer side of the conveying path of the inner frame paper and is on the same side as the centering mark of the inner frame paper. The second guide plate 4 is located on the inner side of the conveying path of the inner frame paper and is opposite to the inner frame paper guide device 10. The two cooperate to realize the conveying guidance of both sides of the inner frame paper, so that the inner frame paper can be smoothly conveyed to the scoring roller.

[0127] Among them, Figure 1-Figure 8As shown, the inner frame paper guiding device 10 of this embodiment includes a first guide plate 1, a support seat 3 and two rolling devices 2.

[0128] The first guide plate 1 is connected to the fixing seat 6 to guide the inner frame paper, and the first guide plate 1 is connected to the two rolling devices 2 through the supporting seat 3 to support the two rolling devices 2.

[0129] like Figure 1-Figure 3 As shown, in this embodiment, the first guide plate 1 is used as an outer guide plate, which is located outside the conveying path of the inner frame paper and guides the inner frame paper to be conveyed on the outside. The cross section of the first guide plate 1 is L-shaped, that is, the first guide plate 1 is an L-shaped plate, which includes a vertically extending upright plate 17 and a horizontally extending horizontal plate 18, the horizontal plate 18 is connected to the top end of the upright plate 17, and is bent toward the other side of the inner frame paper relative to the upright plate 17, specifically, is bent toward the inside relative to the upright plate 17.

[0130] A plurality of (specifically three) first mounting holes 16 are provided on the vertical plate 17 of the first guide plate 1, and correspondingly, a first mounting hole 16 is provided on the fixing seat 6, so that the first guide plate 1 can be connected to the fixing seat 6 by passing through the vertical plate 17 of the first guide plate 1 and the first mounting holes 16 on the fixing seat 6, thereby realizing the installation and fixation of the first guide plate 1 on the fixing seat 6.

[0131] There is a certain gap between the transverse plate 18 of the first guide plate 1 and the support surface (not shown) for supporting the inner frame paper located below the transverse plate 18. During transportation, the inner frame paper is located in the gap between the transverse plate 18 of the first guide plate 1 and the support surface (not shown) below, and under the drive of the rotating conveying roller (not shown, located in the box 102, downstream of the scoring roller) and the guiding action of the rotating paper guide roller (not shown), the inner frame paper passes through the gap between the transverse plate 18 of the first guide plate 1 and the support surface below, and flows toward the scoring roller, thereby realizing the conveying and guiding action of the first guide plate 1 on the outside of the inner frame paper.

[0132] Although the first guide plate 1 of this embodiment can guide the inner frame paper on the outside like the outer guide plate in the related art, its structure is not completely the same as the outer guide plate in the related art.

[0133] For example, the length of the first guide plate 1 of this embodiment is greater than that of the outer guide plate in the related art. In other words, the length of the first guide plate 1 is extended compared with that of the outer guide plate in the related art. Specifically, in this embodiment, the length of the first guide plate 1 is 85 to 95 mm, which is longer, and can not only achieve a longer distance of guidance, but also facilitate the setting of the rolling device 2.

[0134] For another example, the first guide plate 1 of this embodiment, in terms of the length direction, not only includes a first plate section 11 provided with a first opening 13 for avoiding the cutter 103, but also includes a second plate section 12 connected to the upstream end of the first plate section 11 along the conveying direction of the inner frame paper. The second plate section 12 is provided with a second mounting hole 19 for connecting with the support seat 3, a through hole 14 for exposing the rolling device 2 and making the rolling device contact with the inner frame paper, and an observation window 15 for observing the state of the inner frame paper. In this way, not only the length of the first guide plate 1 is extended compared with the outer guide plate in the related art, but also the first guide plate 1 has an additional rolling device support function and an inner frame paper observation function compared with the outer guide plate in the related art.

[0135] Specifically, by Figure 2 and Figure 3 It can be seen that in this embodiment, two second mounting holes 19 are provided on the vertical plate 17 of the second plate segment 12, and two second mounting holes 19 are provided on the support seat 3. In this way, the connecting member 5 such as a screw can pass through the vertical plate 17 of the first guide plate 1 and the first mounting hole 16 on the support seat 3 to connect the support seat 3 to the first guide plate 1, so as to achieve the installation and fixation of the support seat 3 on the first guide plate 1. Two through holes 14 are provided on the cross plate 18 of the second plate segment 12. The two through holes 14 are arranged at intervals along the length direction of the first guide plate 1, so that the rolling parts 21 of the two rolling devices 2 can pass through the two through holes 14 respectively and contact the inner frame paper. At the same time, an observation window 15 is provided on the cross plate 18 of the second plate segment 12, and the observation window 15 is located between the two through holes 14, so that the space of the cross plate 18 of the second plate segment 12 is fully utilized.

[0136] The support seat 3 is used to connect the first guide plate 1 and the two rolling devices 2, and support the two rolling devices 2 above the first guide plate 1. Figure 2 as well as Figure 4-Figure 5 As shown, in this embodiment, the support seat 3 includes a first support plate 31 and a second support plate 32. The two second mounting holes 19 on the support seat 3 mentioned above are both arranged on the first support plate 31, so that the support seat 3 is connected to the first guide plate 1 through the first support plate 31. The second support plate 32 is connected to the top of the first support plate 31 and extends along the length direction of the first guide plate 1, and is used to connect with the two rolling devices 2, so that the support seat 3 is connected to the two rolling devices 2 through the second support plate 32.

[0137] Specifically, Figure 2 as well as Figure 4 As shown in FIG. 1 , in this embodiment, the first support plate 31 includes a first plate 34 and a second plate 35. The first plate 34 is vertically arranged and includes a wide section 36 and a narrow section 37 connected in sequence from bottom to top. The length of the narrow section 37 is less than that of the wide section 36 and is connected to the top of the wide section 36, so that Figure 2As shown, when the support seat 3 is installed on the first guide plate 1, the first support plate 31 can avoid the observation window 15 on the first guide plate 1 in the length direction, so that the observation window 15 is not completely blocked, but partially exposed, so as to facilitate the observation of the state of the inner frame paper through the observation window 15. The second plate 35 is connected to the top of the narrow section 37, has the same length as the narrow section 37, and is bent toward the other side of the inner frame paper relative to the first support plate 31. Specifically, it is bent toward the inner side of the inner frame paper relative to the first support plate 31 to support the second support plate 32. Figure 4 As shown, the second plate 35 is provided with two assembly holes 38. Figure 5 As shown, two assembly holes 38 are provided on the second support plate 32 , so that the connection between the first support plate 31 and the second support plate 32 can be achieved by passing two connecting members 5 such as two screws through the corresponding two groups of assembly holes 38 .

[0138] like Figure 2 As shown, in this embodiment, the second support plate 32 is connected to the second plate 35 of the first support plate 31, and extends along the length direction of the first guide plate 1, and is longer than the second plate 35. Figure 2 and Figure 5 As shown, in this embodiment, the two assembly holes 38 on the second support plate 32 mentioned above are located in the middle of the length direction of the second support plate 32. In addition, a notch 33 and two connecting holes 27 are provided at both ends of the length direction of the second support plate 32 for cooperating with the rolling device 2, so that the two rolling devices 2 are located at both ends of the length of the second support plate 32 and are arranged at intervals along the length direction of the first guide plate 1. Among them, the two notches 33 are both U-shaped and are respectively located directly above the two through holes 14 on the first guide plate 1 to accommodate the rolling parts 21 of the two rolling devices 2. The two connecting holes 27 located at the same end of the length direction of the second support plate 32 are located on both sides of the notch 33 along the width direction of the second support plate 32 to achieve connection with the support shaft 22 of the rolling device 2. In this embodiment, the thickness of the second support plate 32 is relatively thin, which is 0.1-1 mm, so as to adjust the height position of the two rolling devices 2.

[0139] Two rolling devices 2 are connected to the second support plate 32 at intervals along the length direction of the first guide plate 1, and are used to roll the inner frame paper at different positions in the conveying direction of the inner frame paper to improve the conveying stability of the inner frame paper. Figure 2 as well as Figure 6-Figure 8As shown, in this embodiment, the two rolling devices 2 are respectively located at the two through holes 14, and each includes a rolling member 21, a support shaft 22 and two limiting members 23. Among them, the axial direction of the support shaft 22 is along the width direction of the second support plate 32 (also the width direction of the first guide plate 1, or the transverse direction of the conveying direction of the inner frame paper), and two connecting holes 27 corresponding to the pair of connecting holes 27 at one end of the length direction of the second support plate 32 are provided thereon, so that the two connecting members 5 can pass through the corresponding connecting holes 27 to connect the support shaft 22 to the second support plate 32, thereby realizing the installation and fixation of the rolling device 2 on the support seat 3. The rolling member 21 is a bearing 24, which is sleeved on the support shaft 22 and axially limited by the two limiting members 23. The two limiting members 23 are both retaining springs 25, which are clamped in the two clamping grooves 26 on the support shaft 22 and are located outside the axial ends of the bearing 24 to limit the bidirectional axial movement of the bearing 24.

[0140] Based on the above-mentioned structural setting, the inner frame paper guide device 10 of this embodiment can effectively improve the conveying stability of the inner frame paper. Because, during the conveying process of the inner frame paper, the lowest points of the two bearings 24 are in contact with the inner frame paper, rolling friction between the inner frame paper and the inner frame paper is rolled, so that the curling degree of the inner frame paper can be effectively reduced, the flatness of the inner frame paper can be improved, and the left and right shaking of the inner frame paper can be reduced, thereby improving the conveying stability of the inner frame paper, reducing the risk of paper squeezing, and improving the accuracy of centering mark recognition, which is conducive to achieving a more efficient, high-quality, low-consumption, and low-cost inner frame paper supply and packaging process. In addition, the second support plate 32 is elastic, so that the height position of the two bearings 24 is adjustable, which is convenient for the two bearings 24 to always maintain good contact with the inner frame paper during normal conveying, and convenient for meeting the different requirements of the normal conveying process and the replacement process of new and old paper.

[0141] In order to guide the inner frame paper on the opposite side of the inner frame paper guide device 10, as shown in FIG. Figure 1 As shown, the second guide plate 4 is arranged on the opposite side of the first guide plate 1, and is used to guide the inner frame paper on the inner side. Therefore, the second guide plate 4 of this embodiment can play the same role as the inner guide plate in the related art, that is, the second guide plate 4 is used as the inner guide plate.

[0142] However, if Figure 1 , Figure 2 and Fig. 9As shown, the second guide plate 4 of this embodiment is not the same in structure as the inner guide plate in the related art, but has a structure substantially the same as the first guide plate 1. Specifically, in this embodiment, the length of the second guide plate 4 is the same as that of the first guide plate 1. In this case, the length of the second guide plate 4 is also extended relative to the inner guide plate in the related art. Moreover, the second guide plate 4 has a third plate segment 41 directly opposite to the first plate segment 11 of the first guide plate 1 and a fourth plate segment 42 directly opposite to the second plate segment 12 of the first guide plate 1. At the same time, the third plate segment 41 is provided with a second opening 43 equivalent to the first opening 13 of the first plate segment 11, and the fourth plate segment 42 is provided with an observation port 44 equivalent to the observation window 15 on the second plate segment 12. In this way, the second guide plate 4 is substantially symmetrically arranged on the inner and outer sides of the inner frame paper with the first guide plate 1, so as to better guide the inner frame paper.

[0143] Of course, by Figure 1 , Figure 2 and Fig. 9 It can be seen that in this embodiment, the structure of the second guide plate 4 is not exactly the same as that of the first guide plate 1. The main difference between the two is that the second guide plate 4 is not provided with a rolling device 2, and accordingly, a through hole 14 and a support seat 3 that cooperate with the rolling device 2 are not provided. In this way, the structure can be simplified and the cost can be reduced on the basis of meeting the requirement of stable transportation of the inner frame paper.

[0144] In summary, the inner frame paper guide assembly 101 of this embodiment can effectively improve the conveying stability of the inner frame paper by extending the inner and outer guide plates and providing a rolling device 2 on the outer guide plate.

[0145] The above description is only an exemplary embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
