[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] In existing technology, operators use glue buckets to add adhesive to cigarette rolling and packaging machines. However, the adhesive in the bucket becomes viscous and may even solidify in certain areas after prolonged standing, deteriorating its physical properties. Adhesive solidification affects the bonding of paper rolls, label paper, or outer packaging, reducing product yield. The applicant's research has found that the viscosity and solidification are caused by the increased intermolecular forces in the adhesive due to prolonged stagnation, leading to increased viscosity and reduced fluidity. The adhesive near the inner wall of the bucket has particularly strong adhesion to the bucket, resulting in higher viscosity there. Furthermore, the rapid heat exchange between the inner wall of the bucket and the external environment causes the adhesive near the inner wall to dissipate heat more quickly, making it more prone to thickening.

[0041] To solve the above-mentioned technical problems, the present invention provides an adhesive supply device for conveying adhesive to a cigarette rolling machine, such as... Figure 1 and Figure 2As shown, the glue supply device includes a glue tank 1, a stirring mechanism 2, and a drive mechanism 5. The glue tank 1 is used to hold the glue liquid. The stirring mechanism 2 is partially located inside the glue tank 1 and includes a scraper 3 that can move within the glue tank 1. The scraper 3 has a scraping edge 4 that contacts the inner wall of the glue tank 1. The drive mechanism 5 is located outside the glue tank 1 and connected to the stirring mechanism 2. The drive mechanism 5 drives the scraper 3 to move.

[0042] By adopting the above technical solution, a stirring mechanism 2 is installed inside the glue bucket 1, and the scraper of the stirring mechanism 2 moves inside the glue bucket 1, driving the glue liquid inside the glue bucket 1 to keep it in motion. This keeps the molecules in the glue liquid active, preventing them from combining, thus maintaining the fluidity of the glue liquid and preventing it from becoming viscous and solidifying. In this application, the edge of the scraper is set to contact the inner wall of the glue bucket 1. The scraper 3 separates the glue bucket 1 from the glue liquid, preventing the glue liquid from sticking to the inner wall of the glue bucket 1 and solidifying on the inner wall, ensuring the stability of the physical properties of the glue liquid. Furthermore, during the stirring process, the stirring mechanism 2 generates friction with the glue liquid and the inner wall of the glue bucket 1, converting mechanical energy into heat energy. While driving the movement of the glue liquid, it also increases the temperature of the glue liquid, preventing the glue liquid from dissipating heat too quickly and becoming viscous and solidifying.

[0043] Furthermore, such as Figure 1 As shown, the glue bucket 1 is cylindrical, and the stirring mechanism 2 also includes a rotating shaft 6 and a connecting piece 17. The axis of the rotating shaft 6 coincides with the axis of the glue bucket 1, and the rotating shaft 6 is connected to the drive end of the drive mechanism 5, allowing it to rotate around its own axis. A connecting frame 7 is connected to the rotating shaft 6 and can rotate with it. Scrapers 3 are mounted on the connecting frame 7, and the scraping edge 4 extends axially along the glue bucket 1. Specifically, there are four scrapers 3, evenly distributed around the circumference of the rotating shaft 6. The scrapers 3 are made of silicone rubber, and they press against the inner wall of the glue bucket 1, with the scraping edge 4 adhering to the inner wall to improve the effect of scraping off the glue.

[0044] Furthermore, such as Figure 2 As shown, the connecting frame 7 includes multiple connecting plates 8. Each connecting plate 8 includes a first edge 9 and a second edge 10 extending axially along the rotating shaft 6. The first edge 9 is welded to the rotating shaft 6, and the second edge 10 is detachably connected to the scraper 3. A glue leakage hole 11 is also provided on the connecting plate 8 between the first edge 9 and the second edge 10. The glue leakage hole 11 is elongated, allowing the glue to pass through during the rotation of the stirring mechanism 2, thereby reducing the resistance to the rotation of the connecting frame 7 and improving the agitation of the glue.

[0045] Furthermore, such as Figure 2As shown, a plurality of clamping plate assemblies 12 are provided on the second edge 10. Each clamping plate assembly 12 includes two clamping plates 13, which are respectively welded to two parallel surfaces of the connecting plate 8. Each clamping plate 13 has a first connecting hole 14. The scraper 3 is provided with a plurality of connecting blocks 15, each connecting block 15 being accommodated one-to-one between two clamping plates 13 in each clamping plate assembly 12. Each connecting block 15 has a second connecting hole. Each first connecting hole 14 and the second connecting hole are connected by bolts. By clamping the connecting blocks 15 on the scraper 3 with the plurality of clamping plate assemblies 12, the scraper 3 can be kept extending along the axial direction of the glue bucket 1, preventing the scraper 3 from tilting and separating from the glue bucket 1, thereby improving the scraping effect.

[0046] Furthermore, such as Figure 1 As shown, the drive mechanism 5 includes a connector 17, a gear ring 20, a gear 22, and a motor 21. The connector 17 has a first connecting portion 18 and a second connecting portion 19. The first connecting portion 18 is connected to the end of the rotating shaft 6. The gear ring 20 is fitted around the outer circumference of the glue container 1 and can rotate relative to the glue container 1 around its axis. The axis of the gear ring 20 coincides with the axis of the rotating shaft 6. The second connecting portion 19 is connected to the gear ring 20. The drive end of the motor 21 has a gear 22, which meshes with the gear ring 20. The motor 21 drives the gear ring 20 to rotate. Specifically, as shown... Figure 1 As shown, the connector 17 has a cross-shaped structure, including a first connecting part 18, a second connecting part 19, and rods. There are four rods and four connecting parts 19. The first connecting part 18 is disc-shaped and located at the center of the connector 17. The first connecting part 18 is detachably connected to the rotating shaft 6. The rods are positioned between the first connecting part 18 and the second connecting part 19. Each second connecting part 19 is welded to the end face of the gear ring 20. When the motor 21 drives the gear ring 20 to rotate, it can drive the second connecting part 19 to rotate around the axis of the rotating shaft 6, thereby driving the stirring mechanism 2 to rotate.

[0047] Furthermore, such as Figure 1 As shown, the glue supply device also includes a water replenishment mechanism 23, which is used to add water to the glue tank 1. Since the water in the glue will evaporate naturally, adding water to the glue tank 1 through the water replenishment mechanism 23 can prevent the glue from becoming viscous due to water loss. In addition, the water replenishment mechanism 23 can also provide clean water to the glue tank 1 when cleaning it.

[0048] Furthermore, such as Figure 1As shown, the water replenishment mechanism 23 includes a water tank 24, a water supply pipe 25, and a water pump 26. The water tank 24 is located below the glue container 1 and is detachably connected to it. The inlet of the water supply pipe 25 is connected to the water tank 24, and the outlet extends above the glue container 1, with a nozzle 16 facing inwards. The water pump 26 is mounted on the water supply pipe 25 and drives the water in the water tank 24 into the glue container 1. Specifically, the water tank 24 also has a heating unit inside, which heats the water in the tank. The water tank 24 can transfer heat to the glue container 1 above it to heat the glue liquid inside, preventing the glue liquid from cooling down and solidifying.

[0049] Furthermore, such as Figure 1 As shown, the glue supply device also includes a mounting plate 27, on which the water tank 24 and glue bucket 1 are mounted. The bottom of the mounting plate 27 is equipped with casters 31. This facilitates the operator's movement of the glue supply device for use in different work locations.

[0050] Furthermore, such as Figure 1 As shown, the glue tank 1 has an output interface 28 on its side wall, which is located near the bottom of the glue tank 1. The glue supply device also includes a glue supply pipe 29 and a glue supply pump 30. Its input end is connected to the output interface 28, and its output end is provided with a glue supply nozzle 32. The glue supply nozzle 32 is used to supply glue to the outside. The glue supply pump 30 is located on the glue supply pipe 29 and is used to drive the glue in the glue supply pipe 29 to flow out from the glue supply nozzle 32.

[0051] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
