Description

Technical Field

[0001] This utility model relates to the field of splicing paper correction technology, and in particular to a splicing paper correction adjustment structure. Background Technology

[0002] In cigarette production, the tipping paper conveying system is crucial for ensuring the quality of cigarette packaging, and the stability of tipping paper conveying directly affects the appearance and quality of the cigarettes. Currently, a limiting roller is usually installed at the tipping paper inlet of the cigarette machine, with two limiting rings spaced apart on the limiting roller. The distance between the two limiting rings is adapted to the width of the tipping paper. After the tipping paper passes through the area clamped by the two limiting rings on the limiting roller to calibrate the conveying path, it is conveyed to the tipping paper inlet.

[0003] Currently, tipping paper is supplied by roll paper trays. Due to the influence of production process, storage environment and processing precision, the surface of the roll paper trays is prone to unevenness. Moreover, when splicing new and old roll paper trays, the tension control of the cigarette machine and the thickness change at the joint of the new and old paper cause fluctuations in the tipping paper conveying, which can cause the edges to flip, resulting in a large number of waste cigarettes, reducing efficiency and increasing costs.

[0004] Therefore, a paper alignment and adjustment structure is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tipping paper correction and adjustment structure to ensure that the tipping paper always remains flat, avoid tipping paper offset and flipping due to fluctuations, avoid generating a large number of waste cigarettes, significantly improve cigarette production efficiency, and reduce production costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A tipping paper correction and adjustment structure is provided in a cigarette machine. The cigarette machine has a limiting roller extending in a first direction at the tipping paper inlet. The tipping paper is conveyed into the tipping paper inlet along a second direction via the limiting roller. The first direction and the second direction are perpendicular to each other. The tipping paper correction and adjustment structure includes:

[0008] The bracket and two limiting rings are connected to the same side of the bracket and are spaced apart along the first direction. The two limiting rings are sleeved on the limiting roller. The distance between the two limiting rings is the first limiting gap. The first limiting gap is adapted to the width of the splicing paper. The two limiting rings can move synchronously along the limiting roller, driving the bracket to move along the first direction to a preset position and then locking it.

[0009] Two limiting blocks are spaced apart on the bracket along the first direction and extend along the second direction. Each limiting block is a quadrangular prism with a right trapezoidal cross-section. Each limiting block has an inclined surface. The two inclined surfaces of the two limiting blocks are symmetrically arranged facing the inner side of the conveying path of the splicing paper. The distance between the two inclined surfaces and the two connecting ends of the bracket is the second limiting distance. The second limiting distance is adapted to the width of the splicing paper to guide and constrain the edge of the splicing paper that is offset along the first direction, thereby correcting the conveying position of the splicing paper.

[0010] As an optional solution for the paper splicing correction and adjustment structure, the surface of the lower base of the right trapezoid in the cross-section of the limiting block is in contact with the surface of the bracket.

[0011] As an alternative solution for the paper splicing correction adjustment structure, the surfaces of the two inclined surfaces of the two limiting blocks are coated with a wear-resistant and smooth coating.

[0012] As an optional solution for the splice paper correction adjustment structure, the splice paper correction adjustment structure further includes a guide fastener. The limiting block is provided with an oblong hole extending along the first direction. The guide fastener can pass through the oblong hole and connect with the bracket. When the limiting block moves toward or away from the splice paper along the first direction, the guide fastener can slide in the oblong hole. The guide fastener is configured to lock the relative position between the limiting block and the bracket to fix the adjusted second limiting distance.

[0013] As an optional solution for the paper splicing correction adjustment structure, the limiting block is provided with at least two of these waist-shaped holes at intervals.

[0014] As an optional solution for the paper feeding correction adjustment structure, the bracket has a scale mark extending along the first direction corresponding to the position of the limiting block, and the limiting block has an indicator needle pointing to the scale mark, so as to visualize the adjustment amount of the limiting block along the first direction.

[0015] As an optional solution for the splicing paper correction adjustment structure, the splicing paper correction adjustment structure also includes a first fastener. The limiting ring is an open ring, and there are connecting holes on both sides of the opening on the open ring. The opening direction of the two connecting holes is parallel to the radial direction of the open ring, and the axes of the two connecting holes are collinear. The first fastener can be inserted through the two connecting holes in sequence and then locked to fix the relative position of the limiting ring and the limiting roller.

[0016] As an optional solution for the paper feeding correction and adjustment structure, both inner ring surfaces of the two limiting rings are provided with a rubber anti-slip layer.

[0017] As an alternative solution for the splicing paper correction and adjustment structure, the support is a plate-shaped structure.

[0018] As an optional solution for the splice paper correction adjustment structure, the splice paper correction adjustment structure also includes a position detection element configured to detect the splice paper conveying position and to issue an alarm when the detected splice paper conveying position deviates from the correct conveying path along the first direction.

[0019] Beneficial effects:

[0020] This utility model provides a tipping paper correction and adjustment structure. During installation, two limiting rings are connected to the same side of the bracket and are spaced apart along a first direction. The two limiting rings are sleeved on the limiting roller at the tipping paper inlet of the cigarette machine. After the two limiting rings are moved to a preset position along the axial direction of the limiting roller, they are locked to drive the bracket to move to the preset position along the first direction and fix it. The distance between the two limiting rings is a first limiting distance adapted to the width of the tipping paper. Two limiting blocks with a right trapezoidal cross-section extending along a second direction are spaced apart on the bracket along the first direction. The two inclined surfaces of the two limiting blocks are symmetrically arranged facing the inner side of the tipping paper conveying path. The distance between the two connecting ends of the two inclined surfaces and the bracket is a second limiting distance adapted to the width of the tipping paper to guide and constrain the edge of the tipping paper that is offset along the first direction, thereby correcting the conveying position of the tipping paper. In use, the tipping paper first passes through the area clamped by two limiting blocks along the second direction. When it deviates along the first direction, it is guided and corrected by symmetrical inward inclined surfaces on both sides. Then, it is conveyed to the tipping paper inlet through the area clamped by two limiting rings, ensuring accurate and stable tipping paper delivery. This tipping paper correction and adjustment structure has a dual limiting and guiding synergy, ensuring that the tipping paper always remains flat, preventing wrinkles due to excessive constraint or edge flipping due to large deviations. Even when the tipping paper delivery fluctuates, the dynamic adjustment of the inclined surfaces ensures that the tipping paper gradually returns to the correct delivery position, ensuring stable and accurate delivery of the tipping paper to the tipping paper inlet along the second direction. This avoids tipping paper flipping, which generates a large number of waste cigarettes, significantly improving cigarette production efficiency and reducing production costs.

[0031] This embodiment discloses a paper splicing correction and adjustment structure, such as Figures 1-4As shown, the tipping paper correction and adjustment structure is installed in a cigarette machine. A limiting roller 100 extending in a first direction is provided at the tipping paper inlet of the cigarette machine. The tipping paper is conveyed into the tipping paper inlet along a second direction via the limiting roller 100. The first direction and the second direction are perpendicular to each other. The tipping paper correction and adjustment structure includes a support 1, two limiting rings 2, and two limiting blocks 3. The two limiting rings 2 are connected to the same side of the support 1 and are spaced apart along a first direction. The two limiting rings 2 are sleeved on the limiting roller 100, and the distance between the two limiting rings 2 is the first limiting distance, which is adapted to the width of the tipping paper. The two limiting rings 2 can move synchronously along the limiting roller 100, driving the support 1 to move along the first direction to a preset position and then locking it. The two limiting blocks 3 are spaced apart on the support 1 along the first direction and both extend along a second direction. The limiting blocks 3 are quadrangular prisms with a right trapezoidal cross-section. Each of the two limiting blocks 3 has an inclined surface 31. The two inclined surfaces 31 of the two limiting blocks 3 are symmetrically arranged facing the inner side of the tipping paper conveying path, and the distance between the two inclined surfaces 31 and the two connecting ends of the support 1 is the second limiting distance, which is adapted to the width of the tipping paper, so as to guide and constrain the edge of the tipping paper that is offset along the first direction and correct the conveying position of the tipping paper.

[0032] During installation, two limiting rings 2 are connected to the same side of the bracket 1 and are spaced apart along the first direction. The two limiting rings 2 are fitted onto the limiting roller 100 at the paper receiving inlet of the cigarette machine. The two limiting rings 2 are moved along the axial direction of the limiting roller 100 to a preset position and then locked, so as to drive the bracket 1 to move along the first direction to the preset position and fix it. The distance between the two limiting rings 2 is the first limiting distance adapted to the width of the receiving paper. Two limiting blocks 3, which are quadrangular prisms extending along the second direction and have a right trapezoidal cross section, are spaced apart on the bracket 1 along the first direction. The two inclined surfaces 31 of the two limiting blocks 3 are symmetrically arranged facing the inner side of the receiving paper conveying path. The distance between the two inclined surfaces 31 and the two connecting ends connected to the bracket 1 is the second limiting distance. The second limiting distance is adapted to the width of the receiving paper, so as to guide and constrain the edge of the receiving paper that is offset along the first direction and correct the conveying position of the receiving paper. In use, the tipping paper first passes through the area clamped by two limiting blocks 3 along the second direction. When it deviates along the first direction, it is guided and corrected by the symmetrical inward inclined surfaces 31 on both sides. Then, it is conveyed to the tipping paper inlet through the area clamped by two limiting rings 2, ensuring accurate and stable tipping paper delivery. This tipping paper correction and adjustment structure has a dual limiting and guiding synergy, ensuring that the tipping paper always remains flat, preventing wrinkles due to excessive constraint or edge flipping due to large deviations. Even when the tipping paper delivery fluctuates, the dynamic adjustment of the inclined surfaces 31 ensures that the tipping paper gradually returns to the correct delivery position, ensuring stable and accurate delivery of the tipping paper to the tipping paper inlet along the second direction. This avoids tipping paper flipping and the generation of a large number of waste cigarettes, significantly improving cigarette production efficiency and reducing production costs.

[0033] like Figure 3 As shown, in this embodiment, the surface of the lower base of the right trapezoid in the cross-section of the limiting block 3 is in contact with the surface of the bracket 1. This creates a structure where the upper space is larger than the lower space within the area enclosed by the two limiting blocks 3. Combined with the two inclined surfaces 31, this guides the tipping paper, which may have shifted, to slide naturally into the lower space. This design actively regulates the position of the tipping paper, reduces shifting in the first direction, prevents the tipping paper from flipping over and producing defective cigarettes, and ensures that the tipping paper is stably and accurately delivered to the tipping inlet in the second direction, thereby improving cigarette production efficiency and reducing production costs.

[0034] In practical applications, when the fluctuation range of the splice paper is large, the splice paper can deviate onto the inclined surface 31, but will not flip over there. When the fluctuation disappears, the tension on the inclined surface 31 will cause the splice paper to automatically return to the normal feeding position of the splice paper. Therefore, while correcting the deviation, the situation of the splice paper flipping over during the production process is avoided.

[0035] like Figures 3-4 As shown, the extension direction of the inclined plane 31 is from the connection end of the inclined plane 31 and the support 1 to the free end of the inclined plane 31 away from the support 1; the third direction is from the surface of the support 1 away from the tipping paper to the surface of the tipping paper being conveyed, and the third direction is perpendicular to the support 1. The first direction, the second direction, and the third direction are mutually perpendicular, and the extension direction of the inclined plane 31 forms a preset angle with the third direction, which is an acute angle. This allows the tipping paper edge, which is offset along the first direction, to fit more smoothly with the inclined plane 31. The inclined plane 31 accurately guides the tipping paper to correct its position, reduces the impact of tipping paper conveying fluctuations on the tipping paper, avoids edge flipping leading to defective cigarettes, and ensures that the tipping paper is stably and accurately conveyed to the tipping paper inlet along the second direction, thus helping to improve cigarette production efficiency and reduce costs.

[0036] It is worth noting that in this tipping paper correction and adjustment structure, the two inclined surfaces 31 of the two limiting blocks 3 are symmetrically arranged facing the inner side of the tipping paper conveying path. When the tipping paper deviates along the first direction and contacts the inclined surface 31, the positive pressure generated by the inclined surface 31 can be decomposed into a vertical component in the third direction and a horizontal component in the first direction. The vertical component increases the contact friction between the tipping paper and the inclined surface 31, effectively suppressing the tipping paper from flipping over; the horizontal component forms a guiding force along the first direction, helping the tipping paper to reset. At the same time, the directional tension generated by the compression of the two inclined surfaces 31 is opposite to the direction of deviation. Combined with the elastic deformation brought about by the flexibility of the tipping paper, it is transformed into a stable "self-resetting force", which pushes the tipping paper to smoothly return to the correct conveying position along the inclined surface 31. With the constraint of the first limiting distance of the two limiting rings 2, the tipping paper conveying problem caused by fluctuation is reduced, the cigarette waste is reduced, and production stability is ensured.

[0037] Optionally, the preset included angle can be 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, etc., without specific limitations.

[0038] In addition, in this embodiment, the upper base of the right trapezoid in the cross-section of the limiting block 3 is chamfered on both sides to prevent the splicing paper from being damaged or jammed by bumping against the corners during conveying, thus ensuring smooth conveying. The lower base of the right trapezoid in the cross-section of the limiting block 3 is not chamfered on both sides to accommodate the normal fluctuation of the splicing paper edge, avoid the chamfer from obstructing the splicing paper and causing it to flip over, ensure that the splicing paper is conveyed smoothly along the second direction, reduce the generation of waste cigarettes, and help maintain the stable efficiency of cigarette production.

[0039] In this embodiment, the surfaces of the two inclined surfaces 31 of the two limiting blocks 3 are coated with a wear-resistant and smooth coating. On the one hand, the smooth inclined surfaces 31 allow the splice paper to be guided and corrected more smoothly when it deviates, avoiding jamming or edge damage, reducing splice paper deviation and edge flipping caused by fluctuations, ensuring stable and accurate feeding of the splice paper along the second direction, and helping to improve cigarette production efficiency and reduce costs. On the other hand, the enhanced wear resistance of the inclined surfaces 31 can extend the service life of the limiting blocks 3 and reduce the friction when the edge of the splice paper contacts the inclined surfaces 31.

[0040] Alternatively, the wear-resistant and smooth coating can be a ceramic wear-resistant coating, an ultra-hard nano coating, a molybdenum disulfide coating, etc., without specific limitations.

[0041] like Figures 1-3 As shown, the tipping paper correction and adjustment structure also includes a guide fastener 4. The limiting block 3 has a waist-shaped hole 32 extending along the first direction. The guide fastener 4 can pass through the waist-shaped hole 32 and connect to the bracket 1. When the limiting block 3 moves towards or away from the tipping paper along the first direction, the guide fastener 4 can slide within the waist-shaped hole 32. The guide fastener 4 is configured to lock the relative position between the limiting block 3 and the bracket 1 to fix the adjusted second limiting distance. When the limiting block 3 moves along the first direction, the guide fastener 4 can slide within the waist-shaped hole 32, facilitating flexible adjustment of the second limiting distance between the two inclined surfaces 31 to accommodate tipping papers of different widths. After adjustment, the guide fastener 4 locks the relative position between the limiting block 3 and the bracket 1, ensuring the stability of the second limiting distance, effectively preventing tipping paper offset and folding, ensuring accurate feeding of the tipping paper along the second direction, improving the adaptability and efficiency of cigarette production, and reducing costs.

[0042] Specifically, the first limiting distance between the two limiting rings 2 is greater than the width of the splice paper, achieving initial coarse adjustment and limiting of the splice paper. This quickly standardizes the splice paper within the approximate conveying range, reserving safe conveying space for the splice paper while effectively limiting large fluctuations of the splice paper along the first direction over a wide range. This rapidly reduces the fluctuation amplitude and controls the splice paper's movement range within a reasonable range, laying a solid foundation for subsequent precise correction. Based on the real-time conveying status of the splice paper, the second limiting distance between the two inclined planes 31 can be precisely adjusted to be slightly greater than the width of the splice paper. This achieves fine-tuning and precise limiting of the splice paper, accurately correcting minor offsets and limiting its fluctuations within a small range. This further narrows the splice paper's movement space along the first direction, compressing the offset to a minimal extent. The coarse and fine adjustment of the tipping paper correction and adjustment structure not only reduces the difficulty of debugging and eliminates quality risks in the conveying process, but also provides a reliable guarantee for the efficient and stable conveying of tipping paper at the tipping paper inlet. It significantly reduces the offset and folding of tipping paper along the first direction, significantly improves the stability of subsequent processing and the product qualification rate, avoids defective cigarettes, and significantly improves cigarette production efficiency and reduces production costs.

[0043] It is worth noting that the two limit blocks 3 can be adjusted independently or synchronously, allowing for more efficient and precise adjustment of the second limit distance. This flexibly adapts to the fine-tuning requirements of the second limit distance for different widths of tipping paper. Combined with the guiding effect of the inclined surface 31 of the limit block 3, it effectively reduces tipping paper offset and ensures stable and precise feeding of the tipping paper along the second direction, thereby helping to improve cigarette production efficiency and reduce costs.

[0044] like Figure 1 and Figure 3 As shown, the limiting block 3 is provided with at least two oblong holes 32 spaced apart. In this embodiment, the limiting block 3 is provided with two oblong holes 32 spaced apart. On the one hand, the two oblong holes 32 make the limiting block 3 more stable when adjusted along the first direction, ensuring the accurate adjustment of the second limiting distance; on the other hand, the two guide fasteners 4 can respectively position and fix the two points of the limiting block 3, improve the stability of the limiting block 3 on the bracket 1, avoid displacement, effectively reduce the offset and flipping of the splice paper, ensure the stable conveying of the splice paper along the second direction, and help improve the efficiency of cigarette production and reduce costs.

[0045] In other embodiments, the number of waist-shaped holes 32 spaced apart on the limiting block 3 can be three, four, five, etc., and no specific limitation is made here. The number of waist-shaped holes 32 is determined according to the actual length of the limiting block 3 to ensure that the second limiting distance is adjusted accurately and stably, and to ensure the guiding constraint effect of the paper loading.

[0046] In this embodiment, the bracket 1 has a scale mark (not shown) extending along the first direction at the position corresponding to the limiting block 3. The limiting block 3 has an indicator needle (not shown) pointing to the scale mark, so that the adjustment amount of the limiting block 3 along the first direction is visualized. This allows for precise control of the adjustment accuracy of the second limiting distance between the two inclined planes 31, avoiding errors caused by experience-based adjustments, quickly adapting to tipping paper of different widths, ensuring stable and accurate feeding of the tipping paper along the second direction, improving cigarette production efficiency and reducing costs.

[0047] like Figures 1-2 As shown, the tipping paper correction and adjustment structure also includes a first fastener 5. The limiting ring 2 is an open ring, and both sides of the opening 22 on the open ring are provided with connecting holes 21. The opening direction of the two connecting holes 21 is parallel to the radial direction of the open ring, and the axes of the two connecting holes 21 are collinear. The first fastener 5 can be inserted through the two connecting holes 21 in sequence and locked to fix the relative position of the limiting ring 2 and the limiting roller 100. This design allows the two limiting rings 2 to be reliably positioned after synchronous adjustment along the axial direction of the limiting roller 100, ensuring the stability of the first limiting distance and the stable position of the bracket 1, ensuring that the tipping paper is accurately fed to the tipping inlet along the second direction, improving cigarette production efficiency and reducing costs.

[0048] In this embodiment, the inner ring surfaces of the two limiting rings 2 are provided with rubber anti-slip layers. The rubber anti-slip layers can increase the friction between the limiting rings 2 and the limiting rollers 100, prevent them from sliding relative to each other, make the position of the limiting rings 2 more stable after locking, ensure the stability of the first limiting distance, reduce the offset of the tipping paper conveying, ensure the accurate conveying of the tipping paper along the second direction, and help improve the efficiency of cigarette production and reduce costs.

[0049] like Figures 1-4 As shown, the bracket 1 has a plate-like structure. On the one hand, the flat surface of the plate-like structure facilitates its contact with the surface of the tipping paper, reducing frictional resistance during tipping paper conveying and promoting smoother conveying. On the other hand, the flat surface of the plate-like structure provides a stable and compatible mounting base for the limiting block 3, allowing the limiting block 3 to be firmly assembled and more accurately and smoothly adjusted along the first direction when adjusting the second limiting distance. Combined with the limiting effect of the limiting ring 2, it can effectively reduce tipping paper offset and ensure stable and accurate conveying of the tipping paper along the second direction, helping to improve cigarette production efficiency and reduce costs.

[0050] In this embodiment, the tipping paper correction and adjustment structure also includes a position detection component. This component is configured to detect the tipping paper conveying position and issue an alarm when the detected tipping paper conveying position deviates from the correct conveying path along a first direction. The position detection component can detect the tipping paper conveying position in real time and issue an alarm promptly when the tipping paper deviates from the correct conveying path along the first direction, facilitating quick problem detection and handling by staff. This position detection component, together with the coarse adjustment limit of the limit ring 2 and the fine adjustment guide of the limit block 3, achieves tipping paper correction and adjustment, avoiding problems such as tipping paper edge flipping and increased waste cigarettes caused by increased deviation. It ensures stable and accurate conveying of the tipping paper along a second direction, helping to improve the continuity and efficiency of cigarette production and reduce production costs.

[0051] Optionally, the position detection component can be a photoelectric sensor, which has a fast response speed and high detection accuracy, and can accurately capture the position of the splice paper in real time. The position detection component can also be an ultrasonic sensor, which has strong anti-interference ability and can stably detect the position of the splice paper. The type of position detection component is not specifically limited here.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
