[0022] This utility model provides a screen cleaning mechanism for a screen cleaning machine, the structure of which is as follows: Figures 1-4As shown, the device includes a connector 1 connected to a screen cleaning machine. The connector 1 contains a screen 2 with a straight groove 3 on its top side and a connecting box 4. A movable plate 5 is located in the straight groove 3. Two first connecting blocks 8 are fixed to the top of the movable plate 5, and two first cylinders 7 are installed thereon. Both first connecting blocks 8 are movably connected to drive rods 10 via first rotating shafts 9. A drive motor 6 is installed on the side of the connecting box 4, with its output end extending into the connecting box 4 and connected to a first screw 11. A second screw 13, threadedly opposite to the first screw 11, is fixed to the other end of the first screw 11 via a stop block 12. Movable blocks 14 are threaded onto both the first screw 11 and the second screw 13. Second connecting blocks 15 are fixed to the bottom ends of both movable blocks 14. The two second connecting blocks 15 are respectively connected to the other ends of the two drive rods 10. Both ends are movably connected via a second rotating shaft 16; the piston rods of the two first cylinders 7 extend below the moving plate 5 and are connected to a bearing plate 17. Two horizontally positioned second cylinders 18 are mounted at the bottom of the bearing plate 17, their piston rods connected to brush plates 19. A steel brush 31 is fixed to the brush plate 19 near the screen 2. The output of the drive motor 6 drives the first screw 11 and the second screw 13 to rotate, causing the two moving blocks 14 to move one end of the drive rod 10 inward. At this time, the other ends of the two drive rods 10 move the steel brush 31 downward. Then, the piston rods of the two first cylinders 7 drive the bearing plate 17 and the steel brush 31 to continue moving downward. Finally, the piston rods of the two second cylinders 18 move the brush plate 19 towards the screen 2, causing the steel brush 31 to contact the screen 2 for cleaning. Using the screen cleaning mechanism of the screen cleaning machine, the screen 2 can be cleaned thoroughly without disassembly, making it convenient for the operator.

[0023] Furthermore, the movable plate 5 is connected to the top surface inside the connecting box 4 by several first telescopic rods 20, which are used to support the horizontal up and down movement of the movable plate 5 and prevent it from shifting.

[0024] Furthermore, limit blocks 21 are fixed around the inner wall of connector 1, and screws 22 are connected around the screen 2. The number of screws 22 is the same as that of limit blocks 21 and they correspond one-to-one. One end of the screw 22 also passes through the limit block 21 and is threaded with a nut 23.

[0025] Furthermore, a fixing block 24 is fixed to the bottom of the support plate 17. The fixing block 24 is connected to the brush plate 19 through the second telescopic rod 25 and is used to support the horizontal linear movement of the brush plate 19.

[0026] Furthermore, two first mounting blocks 26 are fixed on both sides of the bottom of the connecting box 4. Several first mounting blocks 26 are connected to the connector 1 by screws 27 to install the connecting box 4.

[0027] Furthermore, a bearing 28 is fixed to the inner side wall of the connecting box 4. The bearing 28 is connected to the other end of the second screw 13 to support the rotation of the second screw 13.

[0028] Furthermore, a second mounting block 29 is fixed on both sides of the connector 1, and each of the two second mounting blocks 29 has a mounting hole 30 to facilitate the installation of the connector 1 on the screen cleaning machine.

[0029] The working principle of this utility model is as follows: First, start the drive motor 6, the two first cylinders 7 and the two second cylinders 18. The output end of the drive motor 6 drives the first screw 11 and the second screw 13 to rotate, so that the two moving blocks 14 drive one end of the drive rod 10 to move inward. At this time, the other end of the two drive rods 10 drives the steel brush 31 to move downward. At the same time, the piston rods of the two first cylinders 7 drive the bearing plate 17 and the steel brush 31 to continue to move downward. Finally, the piston rods of the two second cylinders 18 drive the brush plate 19 to move towards the screen 2, so that the steel brush 31 contacts the screen 2 for cleaning.

[0030] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
