The sliding hole 408 is a vertical hole. The cross-sectional dimensions of the sliding hole 408 are adapted to the cross-sectional dimensions of the rotating base 411.

[0047] The effect achieved by the entire adjustment device 4 is that the moving frame 405 reciprocates on the main body 1 of the cleaning machine, and the rack 409 at the bottom of the moving frame 405 drives the toothed ring 412 on the surface of the rotating base 411 to rotate, while cleaning the valve block that limits the surface of the bearing plate 413.

[0048] like Figure 7 and Figure 8As shown, the auxiliary device 5 includes a fixed rod 510, both ends of which are fixedly connected with the bearing plate 413, and the arc surface of the fixed rod 510 is rotatably connected with a rotating plate 501, the cross section of the rotating plate 501 is in the shape of "L", the inner wall of the mounting frame 414 is fixedly connected with a connecting plate 503, the surface of the connecting plate 503 is fixedly connected with a plurality of clamping blocks 504, the cross section size of the plurality of clamping blocks 504 is adapted to the cross section size of the rotating plate 501, the bottom end of one side of the rotating plate 501 is provided with an inlay groove 506, the inner wall of the inlay groove 506 is slidably connected with a sliding rod 509, the side wall of the bearing plate 413 is provided with a connecting hole 507, the inner wall of the connecting hole 507 is slidably connected with the arc surface of the sliding rod 509, the arc surface of the sliding rod 509 is threadedly connected with a rotating shaft 508, one side of the rotating shaft 508 is in abutment with the bearing plate 413, both ends of the fixed rod 510 are sleeved with a coil spring 505, both ends of the coil spring 505 are fixedly connected with the bearing plate 413 and the rotating plate 501 respectively, the upper end surface of the rotating plate 501 is fixedly connected with a friction pad 502, and the friction pad 502 is a rubber pad.

[0049] The whole auxiliary device 5 achieves the effect that when the position between the bearing plate 413 and the mounting frame 414 is clamped and limited, the clamping and limiting can be achieved by means of the rotating plate 501 and the clamping blocks 504 on the surface of the connecting plate 503 in the mounting frame 414, so that the adjustment and movement are facilitated.

[0050] As shown in Figure 9 and Figure 10 As shown, the limiting device 6 includes four limiting frames 61, the bottom ends of the four limiting frames 61 are fixedly connected with the upper surface of the bearing plate 413, the inner wall of each of the four limiting frames 61 is clamped with the same limiting frame 62, the cross section of the limiting frame 62 is in the shape of cross, the surface of the limiting frame 62 is clamped with the inner wall of the limiting frame 61, the surface of the limiting frame 62 is provided with a moving groove 63, the cross section size of the moving groove 63 is adapted to the cross section size of the limiting frame 62, the inner wall of the moving groove 63 is slidably connected with a limiting column 65, the bottom end of the limiting column 65 is rotatably connected with a limiting block 64, the cross section of the limiting block 64 is in the shape of "L", the arc surface of the limiting column 65 is threadedly connected with an extrusion shaft 66, the limiting block 64 is a hard alloy block for improving the use strength, the surface of the bearing plate 413 is provided with a plurality of clamping grooves 67, and the plurality of clamping grooves 67 are uniformly distributed on the surface of the bearing plate 413.

[0051] The whole limiting device 6 achieves the effect that when the valve block is supported by the bearing plate 413, the position of the valve block of different sizes can be fixed and regulated by clamping and limiting between the limiting frame 62 and the limiting frame 61.

[0052] The overall working principle is that when the valve block is cleaned by the cleaning machine body 1, multiple valve blocks are easily stacked and overlapped, and it is not convenient to separate and clean the valve block. At this time, the moving frame 405 can reciprocate in the cleaning machine body 1, the servo motor 402 is started, the eccentric block 403 drives the protrusion 404 on one side of the moving frame 405 to abut, the position of the entire moving frame 405 is moved, and then the rack 409 at the bottom of the moving frame 405 drives the gear ring 412 on the surface of the rotating base 411 to rotate, and the valve block on the surface of the bearing plate 413 is rotated. Since there is a gap between the bearing plates 413, the position of the valve block is effectively separated, which facilitates better cleaning of the surface of the valve block.

[0053] When the position between the bearing plate 413 and the mounting frame 414 is limited and fixed, the connecting plate 503 and the clamping block 504 in the mounting frame 414 are connected with the rotating plate 501 on one side of the bearing plate 413 through the fixed rod 510 at this time. In this process, the slide rod 509 slides along the inlaid groove 506 and the connecting hole 507, and the rotating shaft 508 on the surface of the slide rod 509 is rotated and extruded, so that the position of the entire rotating plate 501 is offset. At this time, the position of the entire rotating plate 501 will be adjusted, which is convenient and fast for fixing and limiting between the mounting frame 414, so as to fix and control the position of the bearing plate 413.

[0054] When the bearing plate 413 supports the pump valve block, in order to avoid the position of the valve block from being offset, the limiting frame 61 on the surface of the bearing plate 413 is connected with the limiting frame 62, and then the limiting column 65 and the limiting block 64 are moved by the moving groove 63 on the surface of the limiting frame 62. Then the limiting block 64 extrudes and fixes the valve block.

[0055] The above is only a preferred embodiment of the present application, and does not limit the form of the present application. Any person skilled in the art can modify or change the above disclosed technology content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments without departing from the technical solution content of the present application, according to the technical essence of the present application, still belongs to the protection scope of the technical solution of the present application.
