Description

Technical Field

[0001] This utility model relates to the technical field of cigarette rolling equipment, and in particular to a gluing device and a cigarette rolling machine. Background Technology

[0002] In the tobacco manufacturing industry, filter tip filling machines are key pieces of equipment used to precisely connect filter tips to cigarettes. Among them, the adhesive applicator, as an important component of the filter tip filling machine, directly affects the filling quality of cigarettes and production efficiency.

[0003] However, existing filter tip attaching machines generally face the challenge of controlling the amount of adhesive applied in practical applications. On the one hand, if too little adhesive is applied, the bond between the filter tip and the cigarette is insufficient, easily causing the cigarette to loosen and fall off during subsequent processing or transportation, severely affecting the overall quality of the cigarette. On the other hand, if too much adhesive is applied, excess glue will overflow from the attaching area, clogging the laser-drilled holes on the filter tip, also affecting the overall quality of the cigarette. Utility Model Content

[0004] The purpose of this invention is to provide an adhesive application device and a cigarette rolling machine that can precisely control the amount of adhesive applied, ensuring a firm bond between the filter and the cigarette, while avoiding clogging of the laser perforation, thereby improving cigarette quality and reducing production costs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The gluing device includes a frame, and a conveyor roller, a paper guide block, a gluing assembly, a paper lifting assembly, and a paper guiding assembly mounted on the frame. The gluing assembly includes:

[0007] The gluing roller is rotatably mounted on the frame and is used to apply glue to the splicing paper.

[0008] The control roller is rotatably mounted on the frame. The outer peripheral wall of the control roller is provided with a stepped glue groove extending along its own circumference. From the end of the control roller to the center, the stepped glue groove includes a first groove, a second groove, a third groove and a fourth groove in sequence. The third groove is flush with the end of the control roller. The depth of the second groove and the fourth groove is less than the depth of the first groove. The control roller is in contact with the top glue roller.

[0009] The glue cylinder is mounted on the frame and is used to store glue. The glue control roller is at least partially immersed in the glue cylinder.

[0010] The scraper is mounted on the frame and can abut against the outer peripheral wall of the control roller to scrape off excess glue.

[0011] Optionally, the position of the glue cylinder relative to the control roller is adjustable.

[0012] Optionally, the paper guide assembly includes:

[0013] The bracket is fixed to the frame and has slotted holes.

[0014] The paper guide roller is rotatably connected to the bracket via a paper guide roller shaft. The paper guide roller shaft is slidably disposed within the strip-shaped hole, and the paper guide roller shaft is set at an angle to the bracket.

[0015] Optionally, the bracket is clamped and fixed to the roller seat on the frame.

[0016] Optionally, the paper guide roller assembly further includes a first limiting member, which is clamped between the bracket and the paper guide roller, and the paper guide roller shaft is fixedly connected to the first limiting member;

[0017] A second limiting member is provided at the end of the paper guide roller shaft away from the first limiting member, and the paper guide roller is sandwiched between the first limiting member and the second limiting member.

[0018] Optionally, the inner wall of the strip hole is provided with a protrusion extending along the extension direction of the strip hole. The first fastener is inserted into the strip hole along the side opposite to the paper guide roller, and after the first fastener abuts against the protrusion, the paper guide roller shaft can be threadedly connected to the first fastener.

[0019] Optionally, the paper lifting assembly includes:

[0020] The drive unit is mounted on the rack;

[0021] The connecting arm has one end fixedly connected to the output end of the drive unit, and the other end fixedly connected to the paper lifting roller shaft. The drive unit can drive the connecting arm to rotate, and the paper lifting roller shaft is set at an angle to the connecting arm.

[0022] The pressure roller is rotatably connected to the lifting roller shaft;

[0023] The paper lifting rod is connected to the connecting arm. The paper lifting rod is set parallel to the paper lifting roller shaft and located below the paper lifting roller shaft. The gluing roller is located between the paper guide roller and the paper pressure roller.

[0024] Optionally, the paper lifting assembly further includes a connector, which includes a body and a first clamping part and a second clamping part connected to the body. The first clamping part and the second clamping part are opposite to each other and spaced apart. The body is provided with a first mounting hole for passing through the paper lifting roller shaft. The first mounting hole communicates with the gap between the first clamping part and the second clamping part. The first clamping part and the second clamping part are threadedly connected by a second fastener to clamp the paper lifting roller shaft. The body is clamped between the connecting arm and the pressure roller, and the paper lifting rod is fixed to the body.

[0025] Optionally, the paper lifting roller assembly further includes a third limiting member, which is clamped between the connecting arm and the paper lifting roller, and the paper lifting roller shaft is fixedly connected to the third limiting member;

[0026] A fourth limiting member is provided at the end of the paper lifting roller shaft away from the third limiting member, and the paper lifting roller is clamped between the third limiting member and the fourth limiting member.

[0027] A cigarette rolling machine, including the aforementioned adhesive applicator.

[0028] The beneficial effects of this utility model are:

[0029] The gluing device and cigarette machine provided by this utility model involve feeding paper being conveyed by a conveying roller, passing sequentially over a paper guide block, a paper lifting assembly, a gluing assembly, and a paper guiding assembly. Since the glue control roller is at least partially immersed in the glue cylinder, glue adheres to the outer circumference of the glue control roller during rotation, and the stepped glue groove is filled with glue. As the glue control roller rotates, the scraper can scrape off the excess glue on the outer wall of the glue control roller. Because the third groove of the stepped glue groove is flush with the end of the glue control roller, while the first, second, and fourth grooves are lower than the end of the glue control roller, the scraper can scrape off the glue in the third groove but cannot scrape off the glue in the first, second, and fourth grooves. During rotation, the glue in the first, second, and fourth grooves flows into the corresponding position of the gluing roller, which then rotates to apply the glue to the feeding paper. Finally, the glued feeding paper is conveyed out of the gluing device through the paper guiding assembly, completing the gluing process and allowing it to proceed to the next process.

[0030] By setting stepped glue grooves on the glue control roller, the amount of glue can be differentiated. A first groove is designed at the junction of the filter and the cigarette. This first groove is relatively deep, allowing for the pre-storage of more glue and ensuring a larger application amount. This guarantees proper adhesion and wrapping of the splicing paper to the filter and cigarette, preventing quality issues such as weak adhesion and air leakage due to insufficient glue. The laser-perforated area is a glue-free zone. A third groove is designed corresponding to this glue-free area. A second and fourth groove are designed on either side of the laser-perforated area. The second and fourth grooves are shallow, containing less glue, preventing glue from overflowing into the glue-free area and clogging the laser perforation when the glue roller applies glue to the splicing paper.

[0031] The stepped glue tank design allows for precise control of the amount of glue applied, ensuring a strong bond between the filter and the cigarette while preventing clogging of the laser drilling, thus improving cigarette quality and reducing production costs. Attached Figure Description

[0041] 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.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. 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.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. 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.

[0045] like Figure 1-4 As shown, an embodiment of this utility model provides a gluing device, including a frame 1, and a conveying roller 2, a paper guide block 3, a gluing assembly 4, a paper lifting assembly 6, and a paper guiding assembly 5 mounted on the frame 1. The gluing assembly 4 includes a gluing roller 41, a glue control roller 42, a glue cylinder 43, and a scraper. The gluing roller 41 is rotatably mounted on the frame 1 and is used to apply glue to the receiving paper. The glue control roller 42 is rotatably mounted on the frame 1, and its outer peripheral wall is provided with a stepped glue groove extending circumferentially. From the end to the center of the control roller 42, the stepped glue tank includes a first groove, a second groove, a third groove and a fourth groove in sequence. The third groove is flush with the end of the control roller 42, and the depth of the second groove and the fourth groove is less than the depth of the first groove. The control roller 42 is in contact with the top glue roller 41. The glue cylinder 43 is installed on the frame 1 and is used to store glue. The control roller 42 is at least partially immersed in the glue cylinder 43. The scraper is installed on the frame 1 and can abut against the outer peripheral wall of the control roller 42 to scrape off excess glue.

[0046] like Figure 1 , 2 As shown, the receiving paper 7 first passes over the guide block 3 via the conveyor roller 2. The guide block 3 is used to adjust the positional deviation of the receiving paper 7. Then, the receiving paper 7 passes through the lifting assembly 6. When the equipment is stopped, the lifting assembly 6 lifts the receiving paper 7 to separate the gluing roller 41 from the receiving paper 7. When the equipment is running, the lifting assembly 6 lowers to bring the receiving paper 7 into contact with the gluing roller 41. After that, the receiving paper 7 passes through the gluing roller 41 in the gluing assembly 4. Since the glue control roller 42 is at least partially immersed in the glue cylinder 43, glue will adhere to the outer circumference of the glue control roller 42 during rotation, and the stepped glue tank will be filled with glue. The rotation of 2 allows the scraper to remove excess glue from the outer wall of the glue control roller 42. Since the third groove of the stepped glue groove is flush with the end of the glue control roller 42, and the first, second, and fourth grooves are lower than the end of the glue control roller 42, the scraper can remove the glue in the third groove, but cannot remove the glue in the first, second, and fourth grooves. During the rotation, the glue in the first, second, and fourth grooves will flow into the corresponding position of the glue application roller 41, and then the glue application roller 41 will rotate to apply the glue to the splicing paper 7. Finally, the glued splicing paper 7 is conveyed out of the glue application device through the paper guide assembly 5 to complete the glue application work and enter the next process.

[0047] By setting stepped glue grooves on the glue control roller 42, the amount of glue can be differentiated. A first groove is designed at the junction of the filter and the cigarette. The first groove is relatively deep and can pre-store more glue to apply a larger amount of glue, ensuring that the splicing paper 7 adheres well to the filter and the cigarette, and avoiding quality problems such as weak adhesion and air leakage caused by insufficient glue. The laser-drilled area is a glue-free area. A third groove is designed in the glue-free area where the laser-drilled area is located. A second groove and a fourth groove are designed on both sides of the laser-drilled area. The second and fourth grooves are shallow grooves with less glue, which can prevent glue from overflowing into the glue-free area when the glue application roller 41 applies glue to the splicing paper 7, thus preventing glue from clogging the laser-drilled area.

[0048] The stepped glue tank design allows for precise control of the amount of glue applied, ensuring a strong bond between the filter and the cigarette while preventing clogging of the laser drilling, thus improving cigarette quality and reducing production costs.

[0049] It should be noted that, depending on the actual situation, different depths of stepped glue grooves can be made for cigarettes of different materials and brands. Different amounts of glue can be applied according to the glue application requirements of different positions, thereby achieving more convenient glue amount adjustment and reaching a more precise balance point.

[0050] Furthermore, the position of the glue cylinder 43 relative to the glue control roller 42 is adjustable. By adjusting the position of the glue cylinder 43, the gap between the glue control roller 42 and the glue application roller 41 can be adjusted, thereby adjusting the amount of glue applied.

[0051] Specifically, the bottom of the glue cylinder 43 is provided with a telescopic cylinder. The output end of the telescopic cylinder is fixedly connected to the glue cylinder 43. By controlling the telescopic cylinder to extend and retract, the position of the glue cylinder 43 relative to the glue control roller 42 can be adjusted, thereby adjusting the gap between the glue control roller 42 and the upper glue roller 41.

[0052] Furthermore, the paper guiding assembly 5 includes a bracket 51 and a paper guiding roller 52. The bracket 51 is fixed to the frame 1 and has a strip-shaped hole. The paper guiding roller 52 is rotatably connected to the bracket 51 through a paper guiding roller shaft 53. The paper guiding roller shaft 53 is slidably disposed in the strip-shaped hole and is set at an angle to the bracket 51.

[0053] like Figure 3 As shown, by sliding the guide roller shaft 53 within the strip hole, the guide roller 52 moves synchronously with the guide roller shaft 53. That is, the position of the guide roller 52 relative to the gluing roller 41 is adjustable, and the wrap angle of the receiving paper 7 around the gluing roller 41 is adjustable. The appropriate wrap angle can be selected according to actual needs to improve the gluing quality and gluing stability.

[0054] Optionally, the paper guide roller 53 is arranged perpendicularly to the bracket 51.

[0055] Furthermore, the bracket 51 is clamped and fixed to the roller seat on the frame 1.

[0056] The clamp fixing method is simple to install and easy to operate. The position of the bracket 51 relative to the glue roller 41 can be changed according to actual needs. That is, by loosening the bracket 51 from the frame 1, rotating the bracket 51 to a suitable angle and then tightening it, more adjustment methods can be provided for the relative position of the paper guide roller 52 and the glue roller 41, so that the adjustment range of the paper guide roller 52 is wider.

[0057] Optionally, the bracket 51 has two strip-shaped holes, each equipped with a paper guide roller shaft 53, and the two strip-shaped holes extend at an angle. By allowing the splicing paper 7 to bypass the paper guide roller shaft 53, the direction of the splicing paper 7 can be changed, facilitating subsequent processes for the operator.

[0058] Furthermore, the paper guide assembly 5 also includes a first limiting member 54, which is sandwiched between the bracket 51 and the paper guide roller 52, and the paper guide roller shaft 53 is fixedly connected to the first limiting member 54; a second limiting member 55 is provided at one end of the paper guide roller shaft 53 away from the first limiting member 54, and the paper guide roller 52 is sandwiched between the first limiting member 54 and the second limiting member 55.

[0059] By setting limiting components on both sides of the paper guide roller 52, the paper guide roller 52 can be axially limited, ensuring that the paper guide roller 52 does not move axially when rotating, thus ensuring the stability of the paper guide roller 52 during the conveying process and avoiding fluctuations caused by axial movement during the conveying and gluing of the paper 7.

[0060] Specifically, the first limiting member 54 is a flange, and the second limiting member 55 is a bolt.

[0061] Optionally, the first limiting member 54 and the paper guide roller shaft 53 are integrally formed.

[0062] Furthermore, the inner wall of the strip-shaped hole is provided with a protrusion extending along the extension direction of the strip-shaped hole. The first fastener can be inserted into the strip-shaped hole along the side opposite to the paper guide roller 52, and after the first fastener abuts against the protrusion, the paper guide roller shaft 53 can be threadedly connected to the first fastener. Specifically, the first fastener is an external hexagonal bolt.

[0063] After the first fastener is inserted into the slotted hole and abuts against the protrusion, the head of the external hexagonal bolt is confined to the inner wall of the slotted hole and cannot rotate. The threaded hole of the first limiting member 54 is aligned with the external hexagonal bolt, and the first limiting member 54 is turned with an open-end wrench to achieve a threaded connection with the external hexagonal bolt. This structure allows the first limiting member 54 to fit tightly against the bracket 51, ensuring its stable installation. Simultaneously, it allows the external hexagonal bolt to be embedded within the bracket 51 without affecting its installation. Furthermore, it facilitates the adjustment of the position of the paper guide roller 52, enabling the paper guide roller 52 to move within the slotted hole without disassembling the bracket 51.

[0064] Furthermore, the paper lifting assembly 6 includes a drive unit, a connecting arm 61, a pressure roller 63, and a paper lifting rod 64. The drive unit is mounted on the frame 1. One end of the connecting arm 61 is fixedly connected to the output end of the drive unit, and the other end is fixedly connected to the paper lifting roller shaft 62. The drive unit can drive the connecting arm 61 to rotate. The paper lifting roller shaft 62 and the connecting arm 61 are arranged at an angle. The pressure roller 63 is rotatably connected to the paper lifting roller shaft 62. The paper lifting rod 64 is connected to the connecting arm 61 and is arranged parallel to the paper lifting roller shaft 62 and located below the paper lifting roller shaft 62. The gluing roller 41 is located between the guide roller 52 and the pressure roller 63. Specifically, the drive unit is a rotary cylinder.

[0065] When it is necessary to apply glue to the connector paper 7, the connecting arm 61 is driven to rotate in the forward direction by the drive component. The connecting arm 61 drives the pressure roller 63 to rotate until the pressure roller 63 presses down onto the surface of the connector paper 7, ensuring that the connector paper 7 can effectively and smoothly contact the glue roller 41. Under the pressure of the pressure roller 63, the wrap angle between the connector paper 7 and the glue roller 41 increases, which enhances the stability and uniformity of glue application, thereby making the glue application of the connector paper 7 more uniform.

[0066] When the equipment stops operating, the connecting arm 61 is driven to rotate in the opposite direction via the drive component. The connecting arm 61 drives the pressure roller 63 to rotate until the pressure roller 63 separates from the splice paper 7. The lifting rod 64 then rises, lifting the splice paper 7 and causing it to detach from the glue roller 41. This method shortens the path of the splice paper 7 between the guide block 3 and the guide assembly 5, improving the conveying stability of the splice paper 7.

[0067] Optionally, the paper lifting roller 62 is arranged perpendicularly to the connecting arm 61.

[0068] Optionally, the connecting arm 61 is clamped and fixed to the output end of the drive component, and then the connection is tightened by bolts.

[0069] Furthermore, the paper lifting assembly 6 also includes a connector 65, which includes a body and a first clamping portion 651 and a second clamping portion 652 connected to the body. The first clamping portion 651 and the second clamping portion 652 are arranged opposite to each other and spaced apart. The body has a first mounting hole for the paper lifting roller shaft 62 to pass through. The first mounting hole communicates with the gap between the first clamping portion 651 and the second clamping portion 652. The first clamping portion 651 and the second clamping portion 652 are threadedly connected by a second fastener to clamp the paper lifting roller shaft 62. The body is clamped between the connecting arm 61 and the pressure roller 63, and the paper lifting rod 64 is fixed to the body. Specifically, the connector 65 is a connecting block.

[0070] The connector 65 is clamped to the paper lifting roller shaft 62, and the paper lifting rod 64 is interference-fitted onto the body of the connector 65. The connector 65 can rotate around the paper lifting roller shaft 62, allowing adjustment of the position of the connector 65 relative to the connecting arm 61, and consequently, the position of the paper lifting rod 64 relative to the connecting arm 61. After adjustment to the appropriate position, the connector 65 is threaded to the first clamping part 651 and the second clamping part 652 via a second fastener, thus fixing the connector 65 to the paper lifting roller shaft 62.

[0071] Furthermore, the paper lifting roller assembly also includes a third limiting member 66, which is sandwiched between the connecting arm 61 and the paper lifting roller, and the paper lifting roller shaft 62 is fixedly connected to the third limiting member 66; a fourth limiting member 67 is provided at the end of the paper lifting roller shaft 62 away from the third limiting member 66, and the paper lifting roller is sandwiched between the third limiting member 66 and the fourth limiting member 67.

[0072] By setting limiting components on both sides of the paper pressure roller 63, the paper pressure roller 63 can be axially limited, ensuring that the paper pressure roller 63 does not move axially when rotating, thus ensuring the stability of the paper pressure roller 63 during the feeding and splicing process, and avoiding fluctuations in the feeding and gluing of the splicing paper 7 due to axial movement.

[0073] This utility model provides a cigarette rolling machine, including the above-mentioned glue application device.

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.
