[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a composite mesh cleaning device comprises a cleaning pool 1, a cover plate 2 with an opening on one side is arranged above the cleaning pool 1, an electric push rod 3 is arranged between the cleaning pool 1 and the cover plate 2, the electric push rod 3 is arranged on the inner wall of the side of the cleaning pool 1, and the output end of the electric push rod 3 is fixedly connected to the cover plate 2; at least four groups of fixed frames 7 are arranged in the cleaning pool 1, and every two groups of fixed frames 7 are symmetrically arranged, and a variable pitch structure 4 for driving two fixed frames 7 to move closer to or away from each other is arranged on the inner wall of the cover plate 2, and a driving structure 5 is arranged on the variable pitch structure 4, and the driving structure 5 is respectively arranged on one side of each fixed frame 7,

[0032] The variable pitch structure 4 includes a first slide plate 403, at least three sets of second slide plates 405 are arranged in parallel on one side of the first slide plate 403, and the four fixing frames 7 correspond to the first slide plates 403 and the second slide plates 405 one by one respectively;

[0033] It also includes cleaning brushes 6, at least four groups of cleaning brushes 6 are respectively arranged on the driving structure 5, and are used to brush the screen;

[0034] The fixing assembly 8 is arranged inside the first slide plate 403 and the second slide plate 405 .

[0035] In this embodiment, the cover plate 2, the variable pitch structure 4 and the structure arranged on the variable pitch structure 4 are pushed upward by the electric push rod 3, and then the side plate of the cleaning pool 1 is opened. After the side plate is opened, the screen to be cleaned can be placed between the two fixed frames 7, and then the electric push rod 3 is started to drive the cover plate 2 to descend. When the cover plate 2 drives the variable pitch structure 4 to descend, the first slide plate 403 and the second slide plate 405 are provided with vertical grooves corresponding to the mounting columns 701 on the fixed frame 7. During the descent process, the mounting columns 701 slide into the first slide plate 403 or the second slide plate 405. 05, the fixed frame 7 and the variable pitch structure 4 are fixed by the fixing assembly 8, and then the servo motor 401 is started to drive the first screw 402 to rotate, so that the first slide plate 403 can move left and right, and then the second slide plate 405 can be driven to move through the connecting rod 404, so that the two fixed frames 7 can be close to each other to fix the screen placed between the fixed frames 7, and then water is added to the cleaning pool 1 to initially soak and clean the screen, and at the same time, the driving structure 5 is started to drive two oppositely arranged cleaning brushes 6 to brush the screen from both sides of the screen, so that the cleaning of the screen is more thorough;

[0036] The opening position of the side panel of the cleaning tank 1 is higher than the position of the mounting column 701, so that the side panel does not affect the fixed position of the fixing frame 7 when opened.

[0037] Preferably, the variable pitch structure 4 includes a servo motor 401, which is arranged in the side wall of the cleaning tank 1. The output end of the servo motor 401 is fixedly connected to a first screw 402 that penetrates the side wall of the cleaning tank 1. The outer wall of the first screw 402 is threadedly connected to the first slide 403. The two sides of the first slide 403 are respectively slidably connected to slide rods 406. The second slide 405 is slidably connected to the outer wall of the slide rod 406. The upper surfaces of the first slide 403 and the second slide 405 are fixedly connected to a fixed column, and the outer wall of the fixed column is rotatably connected to a connecting rod 404; every two connecting rods 404 are rotatably connected, and the rightmost connecting rod 404 is rotatably connected to the top of the cover plate 2.

[0038] Specifically, after the screen to be cleaned is placed on a fixed frame 7, the servo motor 401 is started. When the servo motor 401 rotates, the first screw rod 402 can be driven to rotate, and then the first slide plate 403 can be driven to move horizontally on the first screw rod 402. When the first slide plate 403 moves, the connecting rod 404 fixed thereto can be driven to rotate, wherein the rightmost connecting rod 404 is fixed to the cover plate 2, so that when the first slide plate 403 moves, the connecting rod 404 can be driven to shrink toward the side of the fixed connecting rod 404, and when the connecting rod 404 shrinks, the three second slide plates 405 fixed to the connecting rod 404 can be driven to move to one side. When the second slide plate 405 moves, the fixed frame 7 can be driven to move synchronously, so that the gap between two adjacent fixed frames 7 becomes smaller until the two fixed frames 7 contact to fix the screen between the two fixed frames 7, and the screen is cleaned;

[0039] The distance between the second fixed frame 7 and the third fixed frame 7 is greater than the gap between the first and second fixed frames 7, so that when the fixed frames 7 are driven by the variable distance structure 4 to approach each other, there is a gap between every two pairs of fixed frames 7 for the cleaning brush 6 to move.

[0040] Preferably, the driving structure 5 includes a driving motor 501, which is fixedly connected to the outer wall of the first slide 403 or the second slide 405, and the output end of the driving motor 501 is fixedly connected to the second screw 502, which is rotatably connected to the side wall of the first slide 403 or the second slide 405, and the slider 503 is threadedly connected to the second screw 502, and the cleaning brush 6 is fixedly connected to the lower surface of the slider 503.

[0041] Specifically, after the screen between the two fixed frames 7 is fixed under the drive of the variable pitch structure 4, the drive motor 501 is started. When the drive motor 501 is working, it can drive the second screw 502 to rotate. When the second screw 502 rotates, it can drive the slider 503 set on the second screw 502 to move left and right. When the second screw 502 drives the slider 503 to move, it can drive the cleaning brush 6 fixed to the slider 503 to move. The initial positions of each two sliders 503 are different, and are respectively set at the leftmost and rightmost sides of the second screw 502. Therefore, when the cleaning brush 6 moves, the two cleaning brushes 6 move oppositely on both sides of the screen to clean the screen. The cleaning brush 6 can be moved back and forth by driving the motor 501 forward and reversely, so that the screen is brushed multiple times and the screen holes are thoroughly cleaned.

[0042] Preferably, the fixing assembly 8 includes a spring 801, two springs 801 are symmetrically arranged on the inner wall of the first slide 403 or the second slide 405, one end of the spring 801 is fixedly connected with a card bead 802, and two groups of fixing assemblies 8 are arranged in the first slide 403 or the second slide 405; two mounting posts 701 are arranged on the upper surface of the fixing frame 7, and vertical grooves matching the mounting posts 701 are arranged at positions corresponding to the mounting posts 701 on the first slide 403 or the second slide 405, and the two groups of fixing assemblies 8 are symmetrically arranged on both sides of the vertical grooves; two grooves matching the card bead 802 are arranged at the mounting posts 701 corresponding to the card bead 802, and the mounting posts 701 are slidably connected to the outer wall of the card bead 802;

[0043] Specifically, when the electric push rod 3 drives the cover plate 2 and the variable pitch structure 4 to move downward, the initial position of each fixed frame 7 corresponds to the first slide plate 403 or the second slide plate 405 one by one. During the descent process, the mounting column 701 provided on the fixed frame 7 will slide into the vertical groove opened at the bottom of the first slide plate 403 or the second slide plate 405. During the downward movement of the variable pitch structure 4, the mounting column 701 gradually slides into the inside of the vertical groove. When sliding to the top of the mounting column 701 and contacting the card bead 802 in the vertical groove, the mounting column 701 continues to move inward, squeezing the springs 801 on both sides toward both sides. At the same time, the spring 801 also retracts due to the squeezing force. When the mounting column 701 slides to the innermost part, the grooves opened on both sides of the mounting column 701 correspond to the height of the card bead 802. At this time, the spring 801 rebounds and the card bead 802 is stuck in the groove opened on the mounting column 701, so that the variable pitch structure 4 and the fixed frame 7 can be connected, so that the variable pitch structure 4 can drive the fixed frame 7 to move when working.

[0044] Preferably, two slide grooves 101 are provided at the bottom of the inner cavity of the cleaning tank 1 for the fixing frame 7 to slide in the cleaning tank 1 .

[0045] Specifically, when the variable pitch structure 4 drives the fixed frame 7 to slide, the two sides of the bottom end of the fixed frame 7 slide in the slide groove 101. When the variable pitch structure 4 is separated from the fixed frame 7 and the screen is placed in the cleaning tank 1, the fixed frame 7 is stuck in the slide groove 101 through the bottom end to prevent the fixed frame 7 from tilting and falling without support.

[0046] Preferably, a circular hole with a diameter larger than that of the first screw rod 402 is provided in the middle of the second slide plate 405 for the second slide plate 405 to slide.

[0047] Specifically, when the second slide plate 405 is driven to slide by the first slide plate 403, the second slide plate 405 slides through the first screw rod 402. If the first slide plate 403 and the second slide plate 405 are threadedly connected, the first slide plate 403 and the second slide plate 405 will maintain the same distance and move to one side, and the effect of making the two fixed frames 7 close to each other and contacting each other cannot be achieved.
