Description

Technical Field

[0001] This utility model relates to the field of tobacco production equipment technology, and in particular to a latex filtration device for a cigarette making machine. Background Technology

[0002] In the cigarette manufacturing process, latex in the cigarette splicing machine is mainly used in the splicing process. By being applied to the splicing paper, it firmly bonds the filter tip to the cigarette, ensuring the stability of the cigarette structure. However, impurities such as solid particles and agglomerates may be introduced into the latex during production and storage. These impurities can clog the equipment, leading to uneven coating and interrupted glue supply, thus affecting equipment stability and the bonding effect of the cigarette. Therefore, in the splicing process of the cigarette splicing machine, the latex must be filtered before use and added to the splicing unit to prevent impurities in the latex from affecting product quality.

[0003] Currently used latex filtration devices involve horizontally mounting a filter screen on a support, which is then placed inside a storage tank. During use, latex is added from the top of the tank, and gravity forces it through the filter screen. The latex is then discharged from the bottom of the tank, thus filtering the latex. However, due to the high viscosity of latex, frequent cleaning of the filter screen is necessary to maintain filtration efficiency. The side walls of the storage tank are typically made of thin steel plates, which can cause the support and storage tank to bump against each other during filter placement and removal. Over time, this can lead to slight deformation of the storage tank, widening the gaps between the support and the tank side walls. This allows some impurities from the latex to pass through these gaps, affecting the filtration effect.

[0004] Therefore, there is an urgent need to design a latex filtration device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a latex filtration device for a winding machine, which can reduce the gap between the filter plate and the housing to ensure filtration effect.

[0038] like Figures 1 to 6As shown, this embodiment provides a latex filtration device for a winding machine, which includes a housing 1 and a filter plate 3. The top of the housing 1 is open, and two sets of slide rail structures 2 are symmetrically arranged on opposite inner sidewalls of the housing 1. One end of each slide rail structure 2 is flush with the edge of the opening, and the other end abuts against the inner wall of the housing 1. Each slide rail structure 2 includes a first guide rail 21 and a second guide rail 22, with a guide groove 23 formed between the first guide rail 21 and the second guide rail 22. The end of the filter plate 3 can be inserted into the guide groove 23, and the filter plate 3 can be slidably disposed within the housing 1 via the slide rail structure 2. The filter plate 3 can divide the interior of the housing 1 into a feed chamber 11 and a discharge chamber 12. Optionally, a first protruding rib 24 is provided on the side of the first guide rail 21 near the filter plate 3, and a sliding groove 321 is formed on the filter plate 3 at a position opposite to the first protruding rib 24, with a guide clearance fit between the first protruding rib 24 and the sliding groove 321.

[0039] Specifically, such as Figure 3 As shown, the first guide rail 21 and the second guide rail 22 are roughly elongated block structures. The first guide rail 21 and the second guide rail 22 are arranged in parallel and spaced apart, and the gap between them forms a guide groove 23. Figure 2 and Figure 4 As shown, the filter plate 3 is roughly rectangular in shape and includes a filter screen 31 and a filter frame 32. The filter screen 31 is disposed inside the frame of the filter frame 32. The two side frames of the filter frame 32 can be inserted into the guide groove 23. The sliding groove 321 is opened on the side of the two side frames opposite to the first guide rail 21.

[0040] The latex filtration device for a winding machine provided in this embodiment adopts a box structure with a top opening and a slide rail structure 2 inside the box 1, with one end flush with the edge of the opening and the other end abutting against the inner wall of the box 1. This allows the filter plate 3 to slide between two sets of slide rail structures 2, facilitating the placement and removal of the filter plate 3. Furthermore, the small gap at the connection between the filter plate 3 and the slide rail structure 2 prevents impurities in the latex from passing through the connection, thus ensuring a good filtration effect. Compared to the prior art, the filter plate 3 in the latex filtration device for a winding machine provided in this embodiment can be directly connected to the box 1 without the need for a support bracket, thereby preventing collisions between the support bracket and the box 1 that could cause deformation of the box 1. Meanwhile, a first protruding ridge 24 is provided on the slide rail structure 2, and a slide groove 321 is opened on the filter plate 3. Through the guide gap between the first protruding ridge 24 and the slide groove 321, even if the box body 1 undergoes slight deformation, the two sides of the box body 1 can be tightened again by the filter plate 3 to prevent large gaps from appearing between the end of the filter plate 3 and the slide rail structure 2, thereby further ensuring the filtration effect.

[0041] It is understood that in some other embodiments, a first protruding rib 24 may be provided on the side of the second guide rail 22 near the filter plate 3, or a first protruding rib 24 may be provided on both the first guide rail 21 and the second guide rail 22 near the filter plate 3. The filter plate 3 may be provided with a groove 321 at the position opposite to the first protruding rib 24, and no limitation is made here.

[0042] like Figure 1 and Figure 5 As shown, the box body 1 has an inlet 13 and a outlet 14 on its opposite side walls. The inlet 13 is connected to the feed chamber 11, and the outlet 14 is connected to the discharge chamber 12. The height of the inlet 13 is higher than the height of the outlet 14. The slide rail structure 2 is inclined from bottom to top away from the inlet 13. Specifically, after the filter plate 3 is installed in the box body 1, unfiltered latex enters the feed chamber 11 through the inlet 13, and is then filtered by the filter plate 3. Impurities remain in the feed chamber 11, and the filtered latex enters the discharge chamber 12. Finally, the filtered latex is discharged from the chamber through the outlet 14. By setting the slide rail structure 2 to be inclined from bottom to top away from the inlet 13, the filter plate 3 is also inclined from bottom to top away from the inlet 13 in the box body 1. This allows the latex falling from the inlet 13 to directly land on the inclined surface of the filter plate 3, increasing the contact area between the latex and the filter plate 3 and improving the filtration efficiency.

[0043] Furthermore, such as Figure 2 and Figure 5 As shown, a first handle 33 is provided at the end of the filter plate 3 away from the housing 1, and the first handle 33 can be accommodated in the discharge chamber 12. Optionally, in this embodiment, the first handle 33 is installed on the end face of the top of the filter frame 32 near the discharge chamber 12, and the installation direction of the first handle 33 is perpendicular to the tilt direction of the filter plate 3. By providing the first handle 33, it is not only convenient for operators to disassemble and assemble the filter plate 3, but also, by placing the first handle 33 in the discharge chamber 12, it is possible to prevent unfiltered latex from adhering to the first handle 33 during the filtration process. It is understood that in some other embodiments, the first handle 33 can also be installed at other angles on the end face of the top of the filter frame 32 near the discharge chamber 12, as long as it is ensured that the first handle 33 is accommodated in the discharge chamber 12, and there is no limitation here.

[0044] like Figure 1 As shown, the housing 1 is also equipped with a feed pipe 8 and a discharge pipe 9. The feed pipe 8 is installed at and connected to the feed inlet 13, and the discharge pipe 9 is installed at and connected to the discharge outlet 14. The feed pipe 8 and discharge pipe 9 facilitate connection to external feeding and receiving equipment. Furthermore, a valve 10 is installed on the discharge pipe 9 to facilitate control of the discharge of filtered latex. Optionally, in this embodiment, the valve 10 is a solenoid valve.

[0045] Furthermore, such as Figure 1 As shown, an observation window 6 is also provided on the side wall of the housing 1. The observation window 6 is used to observe the latex in the discharge chamber 12. Specifically, the observation window 6 has a long structure and is set on the side wall where the slide rail structure 2 is provided. The observation window 6 is located on the side near the discharge port 14, which makes it convenient for the operator to observe the amount of filtered latex in the discharge chamber 12. When the amount of filtered latex is large, the valve 10 is opened to discharge the filtered latex.

[0046] Optionally, the observation window 6 is a structural component made of transparent glass. Transparent glass has a lower manufacturing cost and a smoother surface, which reduces the adhesion between the latex and the observation window 6. This not only prevents the latex from obstructing the view but also avoids waste. It is understood that in some other embodiments, the observation window 6 may also be a structural component made of other transparent materials, and this is not a limitation.

[0047] Furthermore, the observation window 6 is also equipped with scale lines. Specifically, the scale lines are set along the height direction of the observation window 6, and the scale lines are used to mark the corresponding amount of filtered latex at different heights, thereby facilitating operators to accurately control the amount of latex discharged.

[0048] like Figure 1 As shown, a lid 7 is also provided on the top of the housing 1, and the lid 7 is detachably connected to the housing 1. Specifically, during filtration, the lid 7 is placed over the opening at the top of the housing 1 to prevent dust in the air from mixing into the latex and affecting the latex's adhesive properties and filtration efficiency. Furthermore, a second handle 71 is provided on the lid 7, making it easy for operators to open or close the lid 7. It is understood that since the first handle 33 on the filter plate 3 can be accommodated within the discharge chamber 12, the first handle 33 will not affect the closing or closing of the lid 7.

[0049] like Figure 5 and Figure 6 As shown, a base 4 is also provided at the bottom of the housing 1. The filter plate 3 can abut against the base 4. A second protruding rib 41 is provided on the side of the base 4 near the filter plate 3. A groove 322 is provided on the filter plate 3 at the position opposite to the second protruding rib 41, and the second protruding rib 41 can be inserted into the groove 322. Specifically, the groove 322 is provided on the bottom edge of the filter frame 32 on the side opposite to the base 4. By providing the second protruding rib 41 and the groove 322, when the filter plate 3 is installed, the second protruding rib 41 is inserted into the groove 322, which can reduce the connection gap between the filter plate 3 and the base 4 and ensure the filtration effect.

[0050] Furthermore, such as Figure 5As shown, the top surface of the base 4 is an inclined surface, and the end of the top of the base 4 located in the feed chamber 11 is higher than the end of the top of the base 4 located in the discharge chamber 12. This arrangement facilitates the flow of unfiltered latex in the feed chamber 11 to the discharge chamber 12, and the discharge of filtered latex in the discharge chamber 12 from the discharge port 14, thereby improving the filtration efficiency.

[0051] Furthermore, such as Figure 5 As shown, a heating plate 5 is also provided on the base 4, and the heating plate 5 is located inside the discharge chamber 12. The heating plate 5 can heat the filtered latex in the discharge chamber 12 to keep it at a constant temperature for convenient subsequent use.

[0052] The specific operation procedure of the latex filtration device for the winding machine provided in this embodiment is as follows:

[0053] First, the filter plate 3 is installed inside the housing 1 through the slide rail structure 2 from the opening at the top of the housing 1, and the housing cover 7 is placed on the housing 1. Then, the feed pipe 8 is connected to the external feeding equipment, and the discharge pipe 9 is connected to the external receiving equipment, with the valve 10 on the discharge pipe 9 closed. The feeding equipment is started, and the unfiltered latex is transported through the feed pipe 8 to the feed chamber 11 inside the housing 1. The unfiltered latex in the feed chamber 11 is filtered by the filter plate 3 and enters the discharge chamber 12. The filtered latex in the discharge chamber 12 is heated by the heating plate 5 to maintain a constant temperature. The operator checks the amount of filtered latex in the discharge chamber 12 through the observation window 6. When a sufficient amount is reached, the operator opens the discharge valve 10, allowing the filtered latex in the discharge chamber 12 to be discharged from the discharge pipe 9. After a period of operation, when the filter plate 3 needs cleaning, simply open the housing cover 7 and pull the filter plate 3 out of the slide rail structure 2 for cleaning.

[0054] The latex filtration device for a winding machine provided in this embodiment adopts a box structure with a top opening and a slide rail structure 2 inside the box 1, with one end flush with the edge of the opening and the other end abutting against the inner wall of the box 1. This allows the filter plate 3 to slide between two sets of slide rail structures 2, facilitating the placement and removal of the filter plate 3. Furthermore, the small gap at the connection between the filter plate 3 and the slide rail structure 2 prevents impurities in the latex from passing through the connection, thus ensuring a good filtration effect. Compared to the prior art, the filter plate 3 in the latex filtration device for a winding machine provided in this embodiment can be directly connected to the box 1 without the need for a support bracket, thereby preventing collisions between the support bracket and the box 1 that could cause deformation of the box 1. Meanwhile, a first protruding ridge 24 is provided on the slide rail structure 2, and a slide groove 321 is opened on the filter plate 3. Through the guide gap between the first protruding ridge 24 and the slide groove 321, even if the box body 1 undergoes slight deformation, the two sides of the box body 1 can be tightened again by the filter plate 3 to prevent large gaps from appearing between the end of the filter plate 3 and the slide rail structure 2, thereby further ensuring the filtration effect.

[0055] 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.
