Description

Technical Field

[0001] This utility model belongs to the field of latex production technology, and specifically relates to a device for repolymerization reaction of latex for slim cigarette packaging. Background Technology

[0002] Slim cigarette packaging latex mainly refers to water-based adhesives used in the manufacturing process of cigarette hard pack packaging to bond various components. Cigarette factories generate large amounts of waste adhesive, residual adhesive, and tailings when cleaning equipment, changing adhesive types, disposing of expired adhesive, or starting / stopping glue coating machines. Direct disposal not only causes waste but also increases environmental treatment costs. Repolymerization technology provides an effective way to recycle these "waste materials," achieving resource recycling and reducing costs.

[0003] During the collection and temporary storage of expired latex, contaminants can easily be introduced due to poor sealing of storage containers (such as aging of sealing rings or insufficient closure of the cap). If the impure latex is directly subjected to a repolymerization reaction, it will interfere with the reaction process, producing uncontrollable large-particle-size polymers, which will lead to quality defects. Utility Model Content

[0004] In view of the fact that during the collection and temporary storage of expired latex, contaminants are easily introduced due to poor sealing of storage containers (such as aging of sealing rings, insufficient closure of the cap, etc.). If the latex containing impurities is directly subjected to a repolymerization reaction, it will interfere with the reaction process and produce uncontrollable large-particle-size polymers, which will cause quality defects. This utility model proposes a repolymerization reaction device for latex in slim cigarette packaging to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a device for the repolymerization reaction of latex in slim cigarette packaging, comprising a stirring assembly, a preheating assembly disposed on the outer surface of the stirring assembly, a filtration assembly disposed inside the preheating assembly, and an adjusting assembly disposed on the outer surface of the filtration assembly. The stirring assembly is used to disperse latex particles, the preheating assembly is used to preheat the recycled latex, the filtration assembly is used to filter impurities in the latex, and the adjusting assembly is used to adjust the filtration size of the filtration assembly.

[0007] Furthermore, the stirring assembly includes a tank, a motor is fixedly mounted on the top of the tank, a flange is fixedly connected to the outer surface of the motor, the motor is fixedly mounted on the top of the tank via the flange, a stirring shaft is fixedly connected to the output shaft of the motor, the stirring shaft is rotatably connected to the inside of the tank, a discharge pipe is fixedly connected to the bottom of the tank, and a valve is fixedly mounted on the outer surface of the discharge pipe.

[0008] Furthermore, the preheating assembly includes a feed pipe, the lower end of which is fixedly connected to a cap, the bottom of which is fixedly connected to a pressure pipe, a preheating tank fixedly installed at the bottom of the cap, a connecting pipe fixedly connected to the bottom of the preheating tank, the connecting pipe being fixedly connected to the tank body, and an electric heating wire fixedly connected inside the preheating tank.

[0009] Furthermore, the filtration assembly includes a cone located inside the preheating tank, and a first filter screen and a second filter screen are fixedly connected inside the cone screen, wherein the mesh size of the first filter screen is larger than that of the second filter screen.

[0010] Furthermore, the adjustment assembly includes an adjustment ring, a rotating ring is fixedly connected to the bottom of the adjustment ring, the rotating ring is rotatably connected inside the cone, and a third filter screen is fixedly connected inside the adjustment ring.

[0011] Furthermore, the outer surfaces of both the flange and the cover are threaded with multiple sets of bolts. The flange is fixedly installed on the top of the tank body by bolts, and the cover is fixedly installed on the top of the preheating tank by bolts.

[0012] Furthermore, a support leg is fixedly connected to the bottom of the tank, a circular plate is fixedly connected to the bottom of the support leg, a bracket is fixedly connected to the outer surface of the tank, and a square plate is fixedly connected to the top of the bracket.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects a preheating component and a filtering component. The filtering component is located inside the preheating component. The failed latex is poured into the preheating component for heating, which improves the fluidity of the latex and facilitates its passage through the filtering component. Since the size of the contaminants in the latex is larger than the pore size of the filtering component, the contaminants remain on the surface of the filtering component, preventing them from entering the stirring component with the latex.

[0015] 2. This utility model connects the adjusting ring and the cone. The adjusting ring is located at the top of the cone, and the rotating ring at the bottom of the adjusting ring acts as a limit to prevent it from separating from the cone. Pushing the adjusting ring drives the third filter screen to rotate, so that the mesh of the third filter screen is staggered with the mesh of the first filter screen, which can reduce the mesh gap and improve the fineness of filtration. It can be adjusted as needed during use, which is more flexible.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 the utility model.

[0030] Please see Figures 1-8 As shown, this utility model is a device for repolymerization reaction of latex in slim cigarette packaging, including a stirring assembly 1, a preheating assembly 2 disposed on the outer surface of the stirring assembly 1, a filtering assembly 3 disposed inside the preheating assembly 2, and an adjusting assembly 4 disposed on the outer surface of the filtering assembly 3. The stirring assembly 1 is used to disperse the latex particles, the preheating assembly 2 is used to preheat the recycled latex, the filtering assembly 3 is used to filter impurities in the latex, and the adjusting assembly 4 is used to adjust the filter size of the filtering assembly 3.

[0031] The expired latex is poured into preheating component 2 and activated to heat the latex, improving its fluidity. As the latex passes through filter component 3 within preheating component 2, the filter component 3 blocks contaminants in the latex. The filtration fineness of filter component 3 can be adjusted by adjusting component 4. After filtration, the latex in preheating component 2 enters stirring component 1. Stirring component 1 is activated, and it uses high shear force to break up aggregated latex particles, gel clumps, or pre-cured agglomerates, restoring particle fineness. Subsequently, deionized water is added to stirring component 1 to adjust the solid content to the target range and improve fluidity. At the same time, stirring component 1 promotes thorough mixing of deionized water and latex particles, ensuring uniform mixing.

[0032] This invention connects the preheating component 2 and the filtering component 3. The filtering component 3 is located inside the preheating component 2. The failed latex is poured into the preheating component 2 and heated to improve the fluidity of the latex, making it easier for the latex to pass through the filtering component 3. Because the size of the contaminants in the latex is larger than the pore size of the filtering component 3, the contaminants remain on the surface of the filtering component 3, preventing the contaminants from entering the stirring component 1 with the latex.

[0033] In one embodiment, the stirring assembly 1 includes a tank 101, a motor 102 is fixedly mounted on the top of the tank 101, a flange 103 is fixedly connected to the outer surface of the motor 102, the motor 102 is fixedly mounted on the top of the tank 101 via the flange 103, a stirring shaft 104 is fixedly connected to the output shaft of the motor 102, the stirring shaft 104 is rotatably connected to the inside of the tank 101, a discharge pipe 105 is fixedly connected to the bottom of the tank 101, and a valve 106 is fixedly mounted on the outer surface of the discharge pipe 105.

[0034] After the motor 102 is installed on the top of the tank 101 via the flange 103, the stirring shaft 104 on the output shaft of the motor 102 is inserted into the inside of the tank 101. When the motor 102 is started, the output shaft of the motor 102 drives the stirring shaft 104 to rotate inside the tank 101, which allows the latex and deionized water inside the tank 101 to be fully mixed.

[0035] In one embodiment, the preheating component 2 includes a feed pipe 201, a cap 202 fixedly connected to the lower end of the feed pipe 201, a pressure pipe 203 fixedly connected to the bottom of the cap 202, a preheating tank 204 fixedly installed at the bottom of the cap 202, a connecting pipe 205 fixedly connected to the bottom of the preheating tank 204, the connecting pipe 205 being fixedly connected to the tank body 101, and a heating wire 206 fixedly connected inside the preheating tank 204.

[0036] The expired latex is poured into the feed pipe 201. The latex passes through the feed pipe 201 and the cap 202 into the preheating tank 204. The heating wire 206 in the preheating tank 204 is activated to heat the latex and improve its fluidity. The heated latex then enters the interior of the tank 1 through the connecting pipe 205.

[0037] In one embodiment, the filter assembly 3 includes a cone 301 located inside the preheating tank 204. A first filter screen 302 and a second filter screen 303 are fixedly connected inside the cone 301, and the mesh size of the first filter screen 302 is larger than that of the second filter screen 303.

[0038] The heated latex passes through the first filter screen 302 above the cone 301, where the first filter screen 302 performs initial filtration. Subsequently, the latex passes through the second filter screen 303 for secondary filtration. After secondary filtration, the latex enters the tank 1 through the connecting pipe 205.

[0039] In one embodiment, the adjustment component 4 includes an adjustment ring 401, a rotating ring 402 fixedly connected to the bottom of the adjustment ring 401, the rotating ring 402 being rotatably connected inside the cone 301, and a third filter 403 fixedly connected inside the adjustment ring 401.

[0040] Rotate the adjusting ring 401, which rotates at the top of the cone 301 via the rotating ring 402. The third filter 403 inside the adjusting ring 401 rotates accordingly, causing the mesh of the third filter 403 to be staggered from the mesh of the first filter 302, which reduces the mesh gap and makes it easier to adjust the coarseness of the filter.

[0041] In one embodiment, for the flange 103, the outer surfaces of both the flange 103 and the cover 202 are threaded with multiple sets of bolts 5. The flange 103 is fixedly installed on the top of the tank body 101 by the bolts 5, and the cover 202 is fixedly installed on the top of the preheating tank 204 by the bolts 5.

[0042] After passing the bolt 5 through the flange 103, it is threaded to the tank body 101, which can fix the flange 103 to the top of the tank body 101. Similarly, when fixing the cover 202, after fixing the cover 202 to the top of the preheating tank 204, the pressure pipe 203 at the bottom of the cover 202 presses down on the adjusting ring 401 to prevent the adjusting ring 401 from rotating unnecessarily.

[0043] In one embodiment, for the tank 101, a support leg 6 is fixedly connected to the bottom of the tank 101, a circular plate 7 is fixedly connected to the bottom of the support leg 6, a bracket 8 is fixedly connected to the outer surface of the tank 101, and a square plate 9 is fixedly connected to the top of the bracket 8.

[0044] The support legs 6 and the circular plate 7 provide support for the tank body 101. The circular plate 7 increases the ground contact area of ​​the support legs 6. The bracket 8 and the square plate 9 provide a mounting position for the preheating tank 204, allowing the preheating tank to be installed and fixed.

[0045] Through the above technical solution, 1. By connecting the preheating component 2 and the filtering component 3, with the filtering component 3 located inside the preheating component 2, the failed latex is poured into the preheating component 2 for heating, which improves the fluidity of the latex and facilitates its passage through the filtering component 3. Since the size of the contaminants in the latex is larger than the pore size of the filtering component 3, the contaminants remain on the surface of the filtering component 3, preventing them from entering the stirring component 1 with the latex; 2. By connecting the adjusting ring 401 and the cone 301, with the adjusting ring 401 located at the top of the cone 301 and the rotating ring 402 at the bottom of the adjusting ring 401 acting as a limit to prevent it from separating from the cone 301, the adjusting ring 401 drives the third filter screen 403 to rotate, causing the mesh of the third filter screen 403 to be staggered with that of the first filter screen 302, which reduces the mesh gap and improves the fineness of filtration. It can be adjusted as needed during use, making it more flexible.
