[0038] Reference Figure 2 and Figure 5 The connecting mechanism 3 includes two connecting rings 301 for fixed connection with the inlet 5 and the outlet 6. The two connecting rings 301 are fixedly connected to one end of the corresponding inlet 5 and outlet 6, respectively, which serves to stabilize the connection between the inlet and outlet of the filter device. A connecting ring 302 is provided on the opposite side of the two connecting rings 301 for connection with the external conveying pipe. A sealing groove 303 is provided on the opposite side of the two connecting rings 301, which can cooperate with the sealing ring 305 to form a sealing structure and prevent glue leakage. A circular ring 304 is fixedly connected inside the two connecting rings 302 to enhance the structural strength and stability of the connecting rings 302. A sealing ring 305 is slidably connected inside the two sealing grooves 303. When it cooperates with the sealing groove 303, it can effectively seal the connection. The opposite side of the two sealing rings 305 is fixedly connected to the adjacent side of the corresponding connecting ring 302 to ensure the relative position of the sealing ring 305 and the connecting ring 302 is stable.

[0039] Both connecting rings 302 have a fixing component 306 on their outer walls for fastening connecting ring 301 and connecting ring 302, thereby enhancing the stability of the connection. The fixing component 306 includes multiple fixing blocks 3061, which are fixed to the outer wall of connecting ring 301, providing a basic structure for the fixing operation and providing a fixing force point. One side of each fixing block 3061 is fixedly connected to the outer wall of the corresponding connecting ring 301, which plays a role in providing stable support for the fixing component 306 and ensuring the stability of the fixing component 306. One side of each fixing block 3061 has a fixing groove 3062, which cooperates with the limiting block 3064 to achieve positioning.

[0040] Multiple fixing blocks 3063 are fixedly connected to the outer walls of both connecting rings 302, which cooperate with fixing block 3061 to achieve a tight connection. Limiting blocks 3064 are fixedly connected to one side of each of the multiple fixing blocks 3063, which can be inserted into the fixing groove 3062 to achieve initial positioning of the connection and realize the function of precise positioning of the connecting components. Fixing bolts 3065 are rotatably connected to one side of each of the multiple fixing blocks 3061. By tightening the fixing bolts 3065, connecting ring 301 and connecting ring 302 are firmly fixed, thereby further enhancing the stability of the connection.

[0041] Specifically, the sealing groove 303 is located on the side of the connecting ring 301 away from the filter box 4, and slides in conjunction with the sealing ring 305. The sealing ring 305 is fixed inside the connecting ring 302. When the connecting ring 302 approaches the connecting ring 301, the sealing ring 305 is embedded in the sealing groove 303, forming a sealing structure, effectively preventing leakage of the adhesive during transportation. The fixing component 306 further ensures the stability of the connection. Multiple fixing blocks 3061 are fixed on the outer wall of the connecting ring 301, and their fixing grooves 3062 are matched with the limiting blocks 3064 on the fixing blocks 3063 on the outer wall of the connecting ring 302. After insertion, the connection mechanism 3 achieves positioning. Then, the fixing bolt 3065 on one side of the fixing block 3061 is rotated to make it tightly connected with the fixing block 3063. The connecting ring 301 and the connecting ring 302 are firmly fixed by mechanical fastening, which can withstand the pressure of glue delivery and prevent the connection from loosening. When disassembling, simply rotate the fixing bolt 3065 in the opposite direction and pull out the limiting block 3064 to separate the connecting ring 301 and the connecting ring 302. This facilitates equipment maintenance and component replacement. Overall, the connecting mechanism 3 achieves reliable connection and convenient operation through a dual design of sealing and fixing.

[0042] Reference Figure 3 , Figure 4 and Figure 5The outer walls of the two circular rings 304 are slidably connected to the interior of the corresponding connecting ring 301, ensuring good alignment between the connecting ring 302 and the connecting ring 301 during connection. The sizes of the circular rings 304 and the connecting ring 301 are matched to ensure a compact structure and enhance connection stability. Sliding grooves 7 are provided on both the front and rear sides of the moving groove 204, providing sliding tracks for the sliders 8 on the connecting block 206, thus guiding the movement. Sliding sliders 8 are fixedly connected to both the front and rear sides of the connecting block 206, cooperating with the sliding grooves 7 to ensure the smooth movement of the connecting block 206. 6. When the filter screen 202 moves, it is stable and does not deviate, thus ensuring the smoothness of movement. Multiple limit blocks 3064 are slidably connected to the interior of the corresponding fixing grooves 3062, realizing the initial positioning of connecting ring 1 301 and connecting ring 2 302, which facilitates subsequent fixing operations and realizes the function of auxiliary installation positioning. One end of multiple fixing bolts 3065 passes through fixing block 1 3061 and limit block 3064 in sequence. By tightening the fixing bolts 3065, connecting ring 1 301 and connecting ring 2 302 are firmly fixed together, thus realizing the function of strengthening the connection tightness.

[0043] Specifically, the circular ring 304 is fixed inside the connecting ring 2 302, slides against the inner wall of the connecting ring 1 301 and matches its size, enhancing the structural strength of the connecting ring 2 302 and preventing deformation of the connecting ring 2 302 during connection and adhesive delivery. The slider 8 on the connecting block 206 slides in the sliding groove 7 in the moving groove 204, providing guidance for the connecting block 206, making the movement of the filter screen 202 by the connecting block 206 more stable and smooth, and facilitating the position adjustment of the filter screen 202 during filtration and cleaning. The limiting block 3064 is inserted into the fixing groove 3062 to achieve the initial positioning of the connecting ring 1 301 and the connecting ring 2 302. The fixing bolt 3065 passes through the fixing block 1 3061 and the limiting block 3064 and is tightened, further strengthening the connection strength of the connecting ring 1 301 and the connecting ring 2 302.

[0044] Working Principle: When using this adhesive filtration device for decorative paper production, the adhesive enters the filter box 4 through the inlet 5 and is filtered by the filter screen 202. Impurities are intercepted on the filter screen 202, and the filtered adhesive flows out from the outlet 6. The bottom of the filter screen 202 slides against the top of the filter box 4 and slides in cooperation with the inside of the groove 201 to ensure a stable filtration process. When it is necessary to clean the impurities on the filter screen 202, the motor 2101 starts, and its output end drives the right rotating rod 208 to rotate. The roller 2102 at the rear end of the right rotating rod 208 drives the left roller 2102 and the left rotating rod 208 to rotate through the transmission belt 2103. When the rotating rod 208 rotates, multiple cleaning plates 209 fixed on its outer wall clean the impurities on the filter screen 202, causing the impurities to fall off the filter screen 202. During the rotation of the rotating rod 208, the transmission assembly 210 also cleans the impurities. When the cleaning assembly 211 is driven to work, the rotating rod 208 rotates, which drives the cleaning plate 2112 to slide in the cleaning groove 2111. The cleaning plate 2112 can clean any impurities that may remain on the outside of the hollow box 207, preventing the accumulation of impurities from affecting the operation of the equipment. At the same time, the telescopic rod 205 and the connecting block 206 can assist the filter screen 202 in moving up and down and fixing its position to a certain extent. When the cleaning plate 209 cleans the filter screen 202, the telescopic rod 205 can extend and retract, so that the filter screen 202 can adapt to the cleaning action and ensure the cleaning effect. During the filtration process, the telescopic rod 205 can also keep the filter screen 202 in a suitable filtration position. The bracket 203 provides stable support for the entire filtration mechanism 2. The moving groove 204 provides guidance and space for the movement of the connecting block 206 and the telescopic rod 205, realizing effective filtration of the adhesive and automatic cleaning of the filter screen 202.

[0045] Two connecting rings 301 are fixed to one end of the inlet 5 and the outlet 6, respectively. A connecting ring 302 is located on the side of connecting ring 301 away from the filter box 4. Connecting ring 302 is used to connect to the external conveying pipe. During connection, connecting ring 302 moves close to connecting ring 301, causing the sealing ring 305 to slide into the sealing groove 303 to achieve a seal. At the same time, the ring 304 inside connecting ring 302 can enhance the structural strength of connecting ring 302. Then, it is further fixed by fixing component 306: the limiting block 3064 on fixing block 3063 is aligned with the fixing groove 3062 of fixing block 3061 and inserted. After initial positioning, the fixing bolt 3065 is rotated to make it fit with fixing block 3063. The 3063 mechanism tightens the fixing blocks 3061 and 3063, ensuring a tight fit between the connecting rings 301 and 302. The sliding fit between the sealing ring 305 and the sealing groove 303, along with the multiple fixations of the fixing component 306, guarantees the sealing of the connection and prevents glue leakage. During disassembly, the fixing bolt 3065 is rotated in the opposite direction, and the limiting block 3064 is pulled out to separate the connecting rings 301 and 302, facilitating equipment maintenance and component replacement. The entire connection mechanism 3, through the sealing design of the sealing ring 305 and the sealing groove 303, and the mechanical fixing method of the fixing component 306, achieves a reliable connection and convenient disassembly / removal between the filter device and the conveying pipe.
