Description

Technical Field

[0001] This utility model relates to the field of cigarette coating technology, and in particular to a splicing paper auxiliary coating mechanism and a splicing paper coating device. Background Technology

[0002] In the field of cigarette coating, cigarette machines are equipped with a tipping paper coating device, which includes a paper guide, a paper lifting roller, and a coating roller. The tipping paper is guided by the paper guide, passes above the paper lifting roller, and is coated with adhesive at the coating roller. The paper lifting roller can reciprocate relative to the cigarette machine. When the cigarette machine starts, the paper lifting roller descends, and the tipping paper contacts the surface of the coating roller, which then coats the tipping paper with adhesive. When the cigarette machine stops, the paper lifting roller rises, and the tipping paper is removed from the surface of the coating roller, thus preventing the tipping paper from breaking due to prolonged rotation of the coating roller.

[0003] Currently, the paper guide and the glue coating roller are at the same height. After the paper lifting roller descends, the splicing paper is straightened between the paper guide and the glue coating roller. Some of the splicing paper relies on the tension to lean against the glue coating roller for glue coating. The glue coating area is small, the glue coating effect is poor, and the glue coating area cannot be adjusted, which easily causes air leakage in the cigarette due to insufficient glue coating.

[0004] Therefore, there is an urgent need for a splicing paper auxiliary gluing mechanism and a splicing paper gluing device to solve the above problems. Utility Model Content

[0005] The first objective of this invention is to provide an auxiliary gluing mechanism for splicing paper, which makes the gluing area adjustable, expands the gluing area, improves the uniformity of gluing, and avoids air leakage in the packaged cigarettes due to insufficient gluing.

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

[0007] A tipping paper auxiliary gluing mechanism is used to assist in gluing the tipping paper on a cigarette rolling machine. The cigarette rolling machine is also equipped with a guide and a gluing roller. After being guided and centered by the guide, the tipping paper is conveyed to the gluing roller where its surface is coated with glue. The tipping paper auxiliary gluing mechanism includes:

[0008] The bracket and the drive component are provided. The bracket is located downstream of the guide and upstream of the coating roller. The fixed end of the drive component is fixedly connected to the cigarette machine, and the movable end of the drive component is connected to the bracket for transmission. The drive component can drive the bracket to reciprocate along a first direction.

[0009] The device includes a lifting roller, a guide roller shaft, and a pressing roller. The guide roller shaft and the lifting roller both extend along a second direction and are spaced apart on the bracket along a first direction, which is perpendicular to the second direction. The pressing roller is sleeved on the guide roller shaft and is rotatable relative to the guide roller shaft about its axial direction. The lifting roller is located below the receiving paper, and the pressing roller is located above the receiving paper. The receiving paper passes through the area between the lifting roller and the pressing roller.

[0010] When the support moves in the positive direction of the first direction, the pressure roller presses down the splice paper so that the splice paper comes into contact with the glue coating roller; when the support moves in the opposite direction of the first direction, the lifting roller lifts the splice paper so that the splice paper moves away from the glue coating roller and breaks the contact between the two.

[0011] As an optional solution for the splicing paper auxiliary gluing mechanism, the splicing paper auxiliary gluing mechanism further includes a first fastener. The bracket is provided with a waist-shaped hole extending along the first direction. The guide roller shaft passes through the waist-shaped hole and can slide within the waist-shaped hole and be locked by the first fastener, so that the distance between the pressure roller and the lifting roller is adjustable, and the downward pressure of the splicing paper is adjustable.

[0012] As an optional solution for the splicing paper auxiliary gluing mechanism, the splicing paper auxiliary gluing mechanism further includes a first bearing and a second bearing. The inner ring of the first bearing is connected to the first end of the guide roller shaft, and the outer ring of the first bearing is connected to the first end of the pressure roller. The inner ring of the second bearing is connected to the second end of the guide roller shaft, and the outer ring of the second bearing is connected to the second end of the pressure roller.

[0013] As an optional solution for a splicing paper auxiliary gluing mechanism, the splicing paper auxiliary gluing mechanism further includes a positioning cover, a limiting ring, and a second fastener. The positioning cover is disposed at the first end of the guide roller shaft, and the second fastener passes through the positioning cover and is fixedly connected to the guide roller shaft, with the side of the positioning cover abutting against the first end of the pressure roller. The limiting ring is sleeved on the second end of the guide roller shaft and abuts against the second end of the pressure roller to limit the relative position of the pressure roller and the guide roller shaft.

[0014] As an optional solution for the splicing paper auxiliary gluing mechanism, the splicing paper auxiliary gluing mechanism also includes a drive shaft, one end of which is connected to the movable end of the drive member, and the other end of which is connected to the bracket. The drive member can drive the drive shaft to reciprocate along the first direction, so as to drive the bracket to reciprocate along the first direction.

[0015] As an optional solution for the splicing paper auxiliary gluing mechanism, the driving component is a cylinder, and the piston rod inside the cylinder can reciprocate relative to the cylinder. The piston rod is connected to the transmission shaft, and the movement of the piston rod drives the transmission shaft to reciprocate along the first direction.

[0016] As an optional solution for the paper feeding auxiliary gluing mechanism, the end of the paper lifting roller is provided with an external thread, and the bracket is provided with an internal thread that mates with the external thread, so that the paper lifting roller is threadedly connected to the bracket.

[0017] As an optional solution for the splicing paper auxiliary gluing mechanism, the splicing paper auxiliary gluing mechanism also includes a position detection element configured to detect the position of the bracket.

[0018] As an alternative to the splicing paper auxiliary gluing mechanism, the outer periphery of the pressure roller is covered with an elastic layer.

[0019] The second objective of this invention is to provide a tipping paper gluing device. By employing the aforementioned tipping paper auxiliary gluing mechanism, the contact state between the tipping paper and the gluing roller is stably controlled, the wrapping angle between the tipping paper and the gluing roller is increased, the gluing area is expanded, the gluing uniformity is improved, and air leakage is avoided in the packaged cigarettes due to insufficient gluing.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0021] A tipping paper gluing device is installed on a cigarette machine for applying glue to the surface of tipping paper. The tipping paper gluing device includes a guide, a gluing roller, and the aforementioned tipping paper auxiliary gluing mechanism. After being guided and centered by the guide, the tipping paper passes through the clamping area between the lifting roller and the pressing roller of the tipping paper auxiliary gluing mechanism, and is then conveyed to the gluing roller to apply glue to the surface of the tipping paper. The tipping paper auxiliary gluing mechanism is configured to make the tipping paper contact or move away from the gluing roller.

[0022] Beneficial effects:

[0023] This invention provides a splicing paper auxiliary gluing mechanism. When a cigarette machine using this mechanism starts up, the drive unit drives the support to move in the positive direction of the first direction. The support drives the lifting roller, the guide roller shaft, and the pressure roller on the guide roller shaft to move synchronously. The pressure roller presses down on the splicing paper that passes through the area between the pressure roller and the lifting roller, so that the splicing paper contacts the gluing roller for smooth gluing. When the cigarette machine using this mechanism stops, the drive unit drives the support to move in the opposite direction of the first direction. The lifting roller lifts the splicing paper, moving the splicing paper away from the gluing roller and breaking the contact. This tipping paper auxiliary gluing mechanism can precisely control the contact state between the tipping paper and the gluing roller, ensuring that the tipping paper can stably and fully adhere to the surface of the gluing roller, increasing the wrapping angle between the tipping paper and the gluing roller. By adjusting the distance of the pressure roller pressing down on the tipping paper, the gluing area can be adjusted, significantly expanding the gluing area, improving the uniformity of gluing, and preventing air leakage in the packaged cigarettes due to insufficient gluing. At the same time, when gluing is not required, the tipping paper can be lifted by the lifting roller, moving the tipping paper away from the gluing roller, effectively preventing the tipping paper from breaking due to prolonged rotation of the gluing roller.

[0024] This invention provides a tipping paper gluing device. During operation, the tipping paper is guided and centered by a guide, passes through the area between the lifting roller and the pressing roller of the tipping paper auxiliary gluing mechanism, and is then conveyed to the gluing roller for gluing. The tipping paper auxiliary gluing mechanism, through the movement of a drive bracket, causes the pressing roller to press down on the tipping paper to contact the gluing roller, or the lifting roller to lift the tipping paper away from the gluing roller. This tipping paper gluing device can stably control the contact state between the tipping paper and the gluing roller, increase the wrapping angle between the tipping paper and the gluing roller, significantly expand the gluing area, improve gluing uniformity, and prevent air leakage in the packaged cigarettes due to insufficient gluing. Simultaneously, when gluing is not required, the lifting roller can lift the tipping paper away from the gluing roller, effectively preventing the tipping paper from breaking due to prolonged gluing rotation.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment discloses a splicing paper auxiliary gluing mechanism and a splicing paper gluing device, such as Figures 1-4 As shown, the tipping paper gluing device is installed on the cigarette machine and is used to apply glue to the surface of the tipping paper 400. The tipping paper gluing device includes a guide 100, a gluing roller 200, and a tipping paper auxiliary gluing mechanism in this embodiment. After the tipping paper 400 is guided and centered by the guide 100, it passes through the area between the lifting roller 2 and the pressing roller 4 of the tipping paper auxiliary gluing mechanism, and is then conveyed to the gluing roller 200 to apply glue to the surface of the tipping paper 400. The tipping paper auxiliary gluing mechanism is used to make the tipping paper 400 contact with or move away from the gluing roller 200.

[0041] like Figure 1 As shown, when the cigarette machine starts, the lifting roller 2 and the pressing roller 4 effectively limit the tipping paper 400 passing between them. The lifting roller 2 moves, and the pressing roller 4 moves synchronously to press down on the tipping paper 400. This ensures that the tipping paper 400, after being guided to the center by the guide 100, can stably and fully adhere to the surface of the coating roller 200, significantly expanding the coating area and improving the coating effect. Figure 2 As shown, when the cigarette machine stops, the paper lifting roller 2 resets and lifts the splice paper 400 so that the splice paper 400 is separated from the glue coating roller 200, thus preventing the splice paper 400 from breaking due to prolonged glue coating. This can be flexibly adjusted according to the glue coating requirements.

[0042] like Figures 1-4As shown, the tipping paper auxiliary gluing mechanism of this embodiment is used to assist in the gluing of tipping paper 400 on a cigarette machine. The tipping paper auxiliary gluing mechanism includes a bracket 1, a drive component, a lifting roller 2, a guide roller shaft 3, and a pressing roller 4. The bracket 1 is located downstream of the guide 100 and upstream of the gluing roller 200. The fixed end of the drive component is fixedly connected to the cigarette machine, and the movable end of the drive component is drivenly connected to the bracket 1. The drive component can drive the bracket 1 to reciprocate along a first direction. The guide roller shaft 3 and the lifting roller 2 both extend along a second direction and are spaced apart on the bracket 1 along the first direction. The first direction and the second direction are perpendicular to each other. The pressing roller 4 is sleeved on the guide roller shaft 3, and the pressing roller 4 can rotate relative to the guide roller shaft 3 around the axial direction of the guide roller shaft 3. The lifting roller 2 is located below the tipping paper 400, and the pressing roller 4 is located above the tipping paper 400. The tipping paper 400 passes through the area where the lifting roller 2 and the pressing roller 4 are clamped. When the support 1 moves in the positive direction of the first direction, the pressure roller 4 presses down the splice paper 400 so that the splice paper 400 contacts the glue coating roller 200; when the support 1 moves in the opposite direction of the first direction, the lifting roller 2 lifts the splice paper 400 so that the splice paper 400 moves away from the glue coating roller 200 and breaks the contact between the two.

[0043] like Figure 1 As shown, when the cigarette machine using this tipping paper auxiliary gluing mechanism starts, as the drive component drives the support 1 to move in the positive direction of the first direction, the support 1 drives the lifting roller 2, the guide roller shaft 3, and the pressure roller 4 on the guide roller shaft 3 to move synchronously. The pressure roller 4 presses down on the tipping paper 400 that passes through the area between the pressure roller 4 and the lifting roller 2, so that the tipping paper 400 contacts the gluing roller 200 for smooth gluing. Figure 2 As shown, when the cigarette machine using this tipping paper auxiliary coating mechanism stops, as the drive component drives the support 1 in the opposite direction of the first direction, the lifting roller 2 lifts the tipping paper 400, causing the tipping paper 400 to move away from the coating roller 200 and break the contact. This tipping paper auxiliary coating mechanism can precisely control the contact state between the tipping paper 400 and the coating roller 200, ensuring that the tipping paper 400 can stably and fully adhere to the surface of the coating roller 200, increasing the wrapping angle between the tipping paper 400 and the coating roller 200. By adjusting the distance the pressure roller 4 presses down on the tipping paper 400, the coating area can be adjusted, significantly expanding the coating area, improving coating uniformity, and preventing air leakage in the packaged cigarettes due to insufficient coating. At the same time, when coating is not required, the lifting roller 2 can lift the tipping paper 400, moving it away from the coating roller 200, effectively preventing the coating roller 200 from rotating and coating for a long time, which could cause the tipping paper 400 to break.

[0044] When the tipping paper gluing device is working, the tipping paper 400 is guided to the center by the guide 100, passes through the area between the lifting roller 2 and the pressing roller 4 of the tipping paper auxiliary gluing mechanism, and is then conveyed to the gluing roller 200 for gluing. The tipping paper auxiliary gluing mechanism moves by driving the bracket 1, causing the pressing roller 4 to press down on the tipping paper 400 to contact the gluing roller 200, or the lifting roller 2 to lift the tipping paper 400 away from the gluing roller 200. This tipping paper gluing device can stably control the contact state between the tipping paper 400 and the gluing roller 200, increase the wrapping angle between the tipping paper 400 and the gluing roller 200, significantly expand the gluing area, improve the gluing uniformity, and prevent air leakage in the packaged cigarettes due to insufficient gluing. At the same time, when gluing is not required, the tipping paper 400 can be lifted by the lifting roller 2 to move it away from the gluing roller 200, effectively preventing the tipping paper 400 from breaking due to prolonged rotation of the gluing roller 200.

[0045] like Figure 3 As shown, the splicing paper auxiliary gluing mechanism also includes a first fastener 51. The bracket 1 is provided with a waist-shaped hole 11 extending along a first direction. The guide roller shaft 3 passes through the waist-shaped hole 11 and can slide within the waist-shaped hole 11 and be locked by the first fastener 51, so that the distance between the pressure roller 4 and the lifting roller 2 is adjustable, and the downward pressure of the splicing paper 400 is adjustable. The guide roller shaft 3 can slide within the waist-shaped hole 11 of the bracket 1. By locking it with the first fastener 51, the distance between the pressure roller 4 and the lifting roller 2 can be adjusted, thereby adjusting the downward pressure of the splicing paper 400 to adapt to different needs. This controls the contact point between the pressure roller 4 and the splicing paper 400, stably controls the contact between the splicing paper 400 and the gluing roller 200, controls the gluing area on the splicing paper 400, and improves the gluing effect.

[0046] In this embodiment, the first fastener 51 is an M10 hexagonal nut. The internal thread of the M10 hexagonal nut is adapted to the external thread at the end of the guide roller shaft 3. When the guide roller shaft 3 slides along the waist-shaped hole 11 on the bracket 1 to the target position, the guide roller shaft 3 can be securely locked to the bracket 1 by tightening the M10 hexagonal nut, thereby accurately fixing the distance between the paper pressure roller 4 and the paper lifting roller 2, ensuring the stability of the downward pressure of the paper loading 400, and making it convenient to loosen the M10 hexagonal nut when adjusting the distance later, thus improving the ease of operation and work adaptability.

[0047] In other embodiments, the first fastener 51 can also be an M8 hexagonal nut, an M12 hexagonal nut, etc., which can be adapted to the end of the guide roller shaft 3, and no specific limitation is made here.

[0048] like Figure 3As shown, the splicing paper auxiliary gluing mechanism also includes a first bearing 61 and a second bearing 62. The inner ring of the first bearing 61 is connected to the first end of the guide roller shaft 3, and the outer ring of the first bearing 61 is connected to the first end of the pressure roller 4. The inner ring of the second bearing 62 is connected to the second end of the guide roller shaft 3, and the outer ring of the second bearing 62 is connected to the second end of the pressure roller 4. On the one hand, the cooperative structure of the first bearing 61 and the second bearing 62 allows the pressure roller 4 to rotate smoothly and flexibly relative to the guide roller shaft 3, which significantly reduces the frictional resistance during the conveying of the splicing paper 400, preventing damage to the splicing paper 400 due to excessive resistance, and also reduces the wear of the guide roller shaft 3 and the pressure roller 4. On the other hand, in conjunction with the spacing adjustment function, the spacing between the pressure roller 4 and the lifting roller 2 can be stably controlled, ensuring the gluing effect of the splicing paper 400.

[0049] like Figure 3 As shown, the splicing paper auxiliary gluing mechanism also includes a positioning cover 71, a limiting ring 72, and a second fastener 52. The positioning cover 71 is located at the first end of the guide roller shaft 3, and the second fastener 52 passes through the positioning cover 71 and is fixedly connected to the guide roller shaft 3. The side of the positioning cover 71 presses against the first end of the pressure roller 4. The limiting ring 72 is sleeved on the second end of the guide roller shaft 3 and presses against the second end of the pressure roller 4 to limit the relative position of the pressure roller 4 and the guide roller shaft 3. On the one hand, the positioning cover 71 and the limiting ring 72 work together to accurately limit the relative position of the pressure roller 4 and the guide roller shaft 3, preventing the pressure roller 4 from shifting and affecting the pressing effect of the splicing paper 400. On the other hand, combined with the structure of the first bearing 61 and the second bearing 62, it ensures that the pressure roller 4 rotates flexibly, reduces the conveying resistance and component wear of the splicing paper 400, and can stably control the distance between the pressure roller 4 and the lifting roller 2, ensuring the gluing effect of the splicing paper 400.

[0050] In this embodiment, the splicing paper auxiliary gluing mechanism also includes a drive shaft. One end of the drive shaft is connected to the movable end of the drive component, and the other end of the drive shaft is connected to the bracket 1. The drive component can drive the drive shaft to reciprocate along a first direction, thereby driving the bracket 1 to reciprocate along the first direction. This makes the force on the bracket 1 more uniform and the movement more stable. By stably driving the bracket 1 to move, the positions of the lifting roller 2 and the pressing roller 4 can be precisely controlled, thereby stably adjusting the contact or separation state between the splicing paper 400 and the gluing roller 200. This ensures the stability of the gluing process to improve the gluing effect, and also reliably allows the splicing paper 400 to detach from the gluing roller 200 when the machine stops, preventing the splicing paper 400 from breaking.

[0051] In this embodiment, the driving component is a cylinder. The piston rod inside the cylinder can reciprocate relative to the cylinder. The piston rod is connected to the transmission shaft, and the movement of the piston rod drives the transmission shaft to reciprocate along the first direction. Through the stable transmission of the transmission shaft, the support 1 is subjected to uniform force and moves smoothly, so as to accurately control the position of the lifting roller 2 and the pressing roller 4, thereby reliably adjusting the contact or separation state between the splice paper 400 and the glue coating roller 200. This ensures the stability of the glue coating process to improve the glue coating effect, and also allows the splice paper 400 to reliably detach from the glue coating roller 200 when the machine stops, effectively preventing the splice paper 400 from breaking.

[0052] like Figures 3-4 As shown, in this embodiment, the end of the paper lifting roller 2 is provided with an external thread, and the bracket 1 is provided with an internal thread that mates with the external thread, so that the paper lifting roller 2 and the bracket 1 are threadedly connected. At the same time, the threaded connection has strong stability, which can ensure that the position of the paper lifting roller 2 is stable during operation and will not deviate and affect the feeding of the splice paper 400. This ensures that the glue is applied evenly when the splice paper 400 contacts the glue coating roller 200, improving the glue coating effect. It can also reliably cooperate to detach the splice paper 400 from the glue coating roller 200 when the machine stops, preventing breakage.

[0053] In this embodiment, the splicing paper auxiliary gluing mechanism also includes a position detection component, which is used to detect the position of the support 1. The position detection component can provide real-time and accurate feedback on the movement state of the support 1 along the first direction, preventing the support 1 from affecting the lifting roller 2 to lift the splicing paper 400 or the pressing roller 4 to press down the splicing paper 400 due to excessive movement or position deviation. It can promptly detect abnormal positions of the support 1, prevent the splicing paper 400 from being deviated or broken due to malfunction of the support 1, and improve the stability and safety of the gluing process.

[0054] In this embodiment, the position detection component is a photoelectric sensor. The photoelectric sensor can provide real-time and accurate feedback on the movement state of the bracket 1 along the first direction, promptly detect abnormal positions of the bracket 1, prevent the bracket 1 from malfunctioning and causing the splicing paper 400 to deviate or break, and further improve the stability and safety of the gluing process.

[0055] In other embodiments, the position detection component can also be an electromagnetic position sensor, which has a fast response speed, can stably monitor the displacement of the bracket 1, and can promptly identify abnormal problems such as jamming or overtravel of the bracket 1, preventing the splicing paper 400 from being deviated or broken during transport.

[0056] In this embodiment, the outer periphery of the pressure roller 4 is covered with an elastic layer. When the pressure roller 4 presses down on the splice paper 400, the elastic layer can form a flexible contact, avoiding rigid contact that could cause damage or indentation to the splice paper 400, ensuring a tighter and more uniform contact between the splice paper 400 and the glue coating roller 200 during pressing, thus improving the glue coating effect.

[0057] Alternatively, the material of the elastic layer can be nitrile rubber, silicone rubber, etc., without specific limitations.

[0058] In this embodiment, the splicing paper gluing device also includes a paper guide roller 300, which is located downstream of the gluing roller 200. The paper guide roller 300 receives the splicing paper 400 after it has been coated with glue by the gluing roller 200 and guides and conveys the splicing paper 400 to avoid conveying deviation or wrinkles due to the glue layer on the surface of the splicing paper 400 after coating.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
