Description

Technical Field

[0001] This application relates to the field of cigarette machinery and equipment technology, and in particular to a cigarette machine adhesive filtration device. Background Technology

[0002] In the cigarette manufacturing process, the adhesive plays a crucial role. It not only bonds the cigarette paper to form a perfectly circumferential cigarette, but also firmly bonds the filter rod, tipping paper, and cigarette itself together to create the finished product. However, in actual cigarette manufacturing, tobacco shreds, tobacco dust, and other impurities can easily fall into the adhesive, or the surface of the adhesive can easily form a rubbery film due to prolonged exposure to air. These impurities and films can contaminate the adhesive. If these impurities adhere to the cigarette along with the adhesive flow, it will reduce the cigarette's bonding strength, leading to quality defects such as cracked or detached filter tips.

[0003] Currently, cigarette factories also install glue tank filtration devices. For example, patent publication number CN222324414U discloses a filtration device for a cigarette machine glue supply system, including: a glue storage tank; a filter assembly, which includes a trapezoidal filter screen and an annular support plate. The trapezoidal filter screen has evenly spaced filter holes, and the trapezoidal filter screen includes a lower end face and an upper end face. The lower end face of the trapezoidal filter screen is open, and the top of the annular support plate is connected to the lower end face of the trapezoidal filter screen. The top of the annular support plate is located at the bottom of the glue storage tank; a fixing assembly is provided at least on opposite sides of the trapezoidal filter screen to fix the trapezoidal filter screen inside the glue storage tank. However, the above-mentioned filtration device cannot filter the rubber residue generated in the glue tank during the glue addition process in a timely manner.

[0004] For example, patent CN204656103U discloses a filter device for a cigarette machine glue container, including a glue container body with a glue outlet at the center of the bottom, and a hollow built-in filter. The built-in filter is located inside the glue container body and has multiple micropores on its surface for filtering the glue. The bottom of the built-in filter is connected to the glue outlet. This filter device increases the filter screen area, reducing the probability of filter screen clogging. Furthermore, the filter adopts a conical design to prevent impurities in the glue from remaining on the filter screen surface when the glue is poured into the glue container. A certain height is reserved at the bottom of the filter to prevent impurities in the glue from settling and clogging the filter screen. However, the built-in filter in the above-mentioned filter device is a single-stage filter and cannot effectively filter the oxidized glue residue in the glue container. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a cigarette machine glue filtration device, which can effectively and timely filter impurities such as tobacco and rubber in the glue, and avoid glue contamination.

[0006] To achieve the above objectives, this utility model provides a cigarette machine adhesive filtration device, including a support frame installed inside the cigarette machine adhesive tank, and a first filter element and a second filter element sequentially installed on the support frame along the adhesive flow direction. Both the first filter element and the second filter element have an open barrel-shaped structure, and the opening directions of the first filter element and the second filter element are opposite, while the opening direction of the second filter element faces the adhesive flow direction.

[0007] Furthermore, the first filter element is detachably mounted on the support frame near the glue inlet of the glue tank to filter impurities introduced during the glue addition process.

[0008] Furthermore, the second filter element is detachably mounted on the support frame near the glue outlet of the glue tank, and is used to filter impurities generated during the flow of the glue liquid in the glue tank.

[0009] Furthermore, the barrel walls and bottoms of both the first and second filter elements are provided with a number of filter mesh holes.

[0010] Furthermore, the support frame includes a hand-held ring, a second mounting ring for mounting the second filter element, and at least three connecting rods. The hand-held ring is connected to the second mounting ring via the connecting rods, making the support frame a cylindrical truss structure.

[0011] Furthermore, the support frame also includes a first mounting ring for mounting the first filter element, the first mounting ring being mounted on the connecting rod and located between the handheld ring and the second mounting ring.

[0012] Furthermore, the outer edge of the opening end of the first filter element extends radially outward to form a first annular boss, and is mounted on the first mounting ring through the first annular boss.

[0013] Furthermore, the outer edge of the opening end of the second filter element extends radially outward to form a second annular boss, and is mounted on the second mounting ring through the second annular boss.

[0014] Furthermore, mounting holes are provided on the first annular boss and the second annular boss.

[0015] Furthermore, the filter meshes of the first and second filter elements have the same pore size.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This utility model has a simple structure and is easy to install and disassemble. After the filter device has been used for a period of time, it can be easily removed from the plastic bucket, and the first and second filter elements can be disassembled for cleaning. This avoids clogging of the first and second filter elements during long-term use, thereby extending the service life of the filter device.

[0018] This invention utilizes the installation position and structure of the first filter element to filter impurities introduced during the process of adding glue to the glue tank, such as tobacco shreds and a very small amount of tobacco dust; and utilizes the installation position and structure of the second filter element to filter impurities generated during the flow of the glue liquid in the glue tank, such as the glue liquid oxidizing and producing rubber skin during slow flow, which is effectively intercepted by the second filter element to prevent it from entering the subsequent glue tube.

[0019] This invention utilizes a first filter element and a second filter element to achieve two-stage filtration of the adhesive liquid, which can effectively prevent impurities in the adhesive liquid from entering the adhesive tube, reduce potential quality risks in the finished product, and improve the quality of the finished product.

[0030] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, terms such as “installation,” “connection,” and “linkage” used in the description of this application should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand its specific meaning in this application according to the specific circumstances.

[0031] like Figure 1 As shown, this utility model provides a cigarette machine adhesive filtration device, including a support frame 1 installed inside the cigarette machine adhesive tank, and a first filter element 2 and a second filter element 3 sequentially installed on the support frame 1 along the adhesive flow direction. The first filter element 2 and the second filter element 3 are both open barrel-shaped structures, and the opening directions of the first filter element 2 and the second filter element 3 are opposite, while the opening direction of the second filter element 3 faces the adhesive flow direction.

[0032] Furthermore, the filtration device of this application is used in the glue-adding process in cigarette factories. It is installed inside the glue tank of the cigarette machine and is installed in a pull-out manner. Specifically, the support frame 1 of this application matches the size of the glue tank, and the outer diameter of the support frame 1 is smaller than the inlet diameter of the glue tank. When it is necessary to filter the glue liquid, the support frame 1 is inserted into the glue tank from the inlet; when filtration is completed and the filtration device needs to be cleaned, the support frame 1 can be pulled out of the glue tank by hand. Furthermore, the first filter element 2 and the second filter element 3 of this application share the same support frame 1, making the filtration device compact and suitable for scenarios where the internal space of the glue tank is limited. Furthermore, this application utilizes a first filter element 2 with its opening facing away from the direction of glue flow to intercept impurities introduced during the glue application process, such as tobacco shreds, tobacco fragments, and glue lumps. Its barrel-shaped structure can form a bottom-catching effect, preventing impurities from directly entering the glue container. A second filter element 3 with its opening facing the direction of glue flow intercepts rubber skin or secondary scaling generated during the glue flow process. The reverse-opening barrel-shaped structure facilitates the glue flowing to the glue tube by gravity, preventing viscous glue from accumulating at the bottom of the second filter element 3.

[0033] Furthermore, the first filter element 2 of this application is detachably mounted on the support frame 1 near the glue filling port of the glue tank, for filtering impurities introduced during the glue filling process. The opening of the first filter element 2 faces the glue filling port. When the operator adds glue to the glue tank, the glue enters the first filter element 2 and is intercepted by the first filter element 2 to prevent impurities such as tobacco that fall into the glue during the glue filling process from directly entering the glue tank.

[0034] Furthermore, the second filter element 3 of this application is detachably mounted on the support frame 1 near the glue outlet of the glue tank, and is used to filter impurities generated during the flow of the glue liquid in the glue tank. After the glue liquid enters the glue tank, it flows slowly in the glue tank. During the flow, the glue liquid surface is in contact with air for a long time, which easily forms a rubber film. The rubber film flows with the glue liquid by gravity. When it comes into contact with the second filter element 3, the rubber film is intercepted by the second filter element 3, while the remaining glue liquid continues to flow towards the glue tube by gravity through the second filter element 3. Since the installation position of the second filter element 3 of this application is located at the glue outlet of the glue tank, the glue liquid filtered by the second filter element 3 directly enters the glue tube and will not come into contact with air again to form a rubber film.

[0035] Furthermore, the first filter element 2 and the second filter element 3 of this application both have a plurality of filter mesh holes on their walls and bottoms. The evenly distributed filter mesh holes on the walls and bottoms of this application enable multi-directional filtration of the adhesive, improving filtration efficiency. Moreover, the numerous filter mesh holes can disperse the impurity load, preventing localized clogging of the first filter element 2 and the second filter element 3. For example, the filter mesh holes at the bottom can prevent the accumulation of sediment, while the filter mesh holes on the walls utilize fluid dynamics to intercept suspended impurities. In addition, this structural design allows the adhesive to pass through the first filter element 2 and the second filter element 3 from all directions, reducing dead zones caused by unidirectional flow.

[0036] Furthermore, the filter meshes of the first filter element 2 and the second filter element 3 in this application have the same pore size. The pore size is not specifically limited here; it can be designed specifically according to the dimensions of tobacco shreds, tobacco dust, and rubber sheets in the actual production process, for example, a pore size of 1mm. Moreover, by utilizing the first filter element 2 and the second filter element 3 with the same pore size, this application can repeatedly intercept target impurities. Even if the first filter element 2 experiences partial failure due to impurity accumulation, the second filter element 3 can still guarantee the filtration effect, improving the fault tolerance of the device.

[0037] Furthermore, such as Figure 2As shown, the support frame 1 of this application includes a handheld ring 12, a second mounting ring 14 for mounting the second filter element 3, and at least three connecting rods 11. The handheld ring 12 is connected to the second mounting ring 14 via the connecting rods 11, making the support frame 1 a cylindrical truss structure. It also includes a first mounting ring 13 for mounting the first filter element 2, which is mounted on the connecting rods 11 and located between the handheld ring 12 and the second mounting ring 14. The handheld ring 12 of this application has an annular structure, and its inner and outer diameters are the same as those of the first mounting ring 13 and the second mounting ring 14. The outer diameter of the handheld ring 12 is smaller than the diameter of the glue bucket inlet. Three connecting rods 11 are fixedly connected to the handheld ring 12, and the three connecting rods 11 are evenly distributed along the circumference of the handheld ring 12. The fixing methods include, but are not limited to, welding, bonding, and riveting. Three connecting rods 11 are evenly inserted and fixed in the first mounting ring 13 and the second mounting ring 14. The first mounting ring 13 has three first threaded holes 131, and the second mounting ring 14 has three second threaded holes 141. Through the cooperation of the first threaded holes 131, the second threaded holes 141 and the screws, the first mounting ring 13 is installed together with the first filter element 2, and the second mounting ring 14 is installed together with the second filter element 3. Furthermore, in this application, the distance between the first mounting ring 13 and the handheld ring 12 is less than the distance between the first mounting ring 13 and the second mounting ring 14. The distance between the first mounting ring 13 and the second mounting ring 14 is the effective liquid chamber depth of the glue container. This design can shorten the first filtration path and reduce the glue retention time, while the greater distance of the second mounting ring 14 provides sufficient second filtration space. Through the structural design of the support frame 1 described above, the support frame 1 of this application can form a stable spatial support system. The evenly distributed connecting rods 11 can convert the axial load into the axial stress of the rods, and disperse the pressure through the first mounting ring 13 and the second mounting ring 14. This cylindrical truss structure has the advantages of high strength and lightweight, and is suitable for frequent disassembly and assembly conditions, such as disassembling and cleaning the first filter element 2 and the second filter element 3.

[0038] Furthermore, such as Figure 3 As shown, the outer edge of the open end of the first filter element 2 extends radially outward to form a first annular boss 21, which is then mounted on the first mounting ring 13. The first annular boss 21 has first mounting holes 211. Furthermore, the first annular boss 21 has multiple first mounting holes 211 evenly distributed along its circumference, and these holes connect it to the first mounting ring 13. The contact surface between the first annular boss 21 and the first mounting ring 13 is tightened with bolts to form a planar seal, preventing leakage of adhesive from the connection point. The width of the first annular boss 21 is designed to match the width of the first mounting ring 13 to ensure sufficient sealing area. In addition, the multiple first mounting holes 211, when connected by threads, allow for quick assembly and disassembly, facilitating cleaning or replacement of the first filter element 2.

[0039] Furthermore, such as Figure 4 As shown, the outer edge of the open end of the second filter element 3 extends radially outward to form a second annular boss 31, which is then mounted on the second mounting ring 14. The second annular boss 31 has second mounting holes 311. Furthermore, the second annular boss 31 has multiple second mounting holes 311 evenly distributed along its circumference, and these holes connect it to the second mounting ring 14. The contact surface between the second annular boss 31 and the second mounting ring 14 is tightened with bolts to form a planar seal, preventing leakage of adhesive from the connection point. The width of the second annular boss 31 is designed to match the second mounting ring 14 to ensure sufficient sealing area. In addition, the multiple second mounting holes 311, when connected by threads, allow for quick assembly and disassembly, facilitating cleaning or replacement of the second filter element 3.

[0040] Furthermore, the working principle of the filtration device of this application is as follows:

[0041] When the filtration device of this application is required, the device is first assembled. The first filter element 2 and the second filter element 3 are fixed to the support frame 1 by threaded connection. Then the support frame 1 is placed into the glue bucket through the glue bucket inlet. At this time, the device is installed.

[0042] When the glue-adding staff adds glue to the glue bucket, the glue liquid first passes through the first filter element 2 before entering the glue bucket. At this time, impurities such as tobacco shreds, glue blocks, and a small amount of millimeter-sized smoke dust that fall into the glue liquid during the glue-adding process are intercepted in the bucket by the first filter element 2, thus achieving the first filtration of the glue liquid.

[0043] During the continuous glue addition process, the glue enters the effective liquid chamber of the glue tank. As the glue flows slowly, its surface comes into contact with the air, forming a rubber sheet. Under the action of gravity, the rubber sheet falls onto the second filter element 3 and is intercepted by the second filter element 3, thus achieving a second filtration of the glue. At this time, the filtered glue enters the glue tube under the action of gravity, completing the glue addition.

[0044] When there are foreign objects on the first filter element 2 and / or the second filter element 3, the filter device can be removed from the glue bucket by holding the ring 12. Then, loosen the screws to remove the first filter element 2 and / or the second filter element 3, clean them, and then reinstall them in the glue bucket after the above steps are completed for filtration again.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
