A plurality of cleaning ports 103 are arranged at intervals on the upper end surface of the cleaning tray 1 and are respectively connected to the two groups of independent areas. The lower end surface of the cleaning tray 1 is nested with connection ports 102 that are respectively connected to the two groups of independent areas. refer to Figure 7 The pipeline part includes two sets of first pipelines 2 nested inside and outside, and the two sets of first pipelines 2 nested inside and outside are respectively connected to the two sets of connection ports 102. In order to realize the rotation of the cleaning disc 1, the first pipeline 2 is a "Z"-shaped structure, so that when one end of the first pipeline 2 is used as the rotation center axis, it can drive the cleaning disc 1 to make a circular motion; refer to Figure 8The driving part includes a fifth rotating ring 7 connected to the bracket part, the upper end of the fifth rotating ring 7 is rotatably connected to the fourth rotating ring 6, and the inner and outer end surfaces of the fourth rotating ring 6 are both provided with second meshing grooves 601 for meshing transmission, and the second meshing grooves 601 are used for meshing transmission with the connection between the cleaning disc 1 and the first pipeline 2, so that the cleaning disc 1 can be driven to move in a circular motion; refer to Figure 2 The bracket part includes a sliding bracket 8, a mounting bracket 801 for rotating and fixing the pipeline part is installed at the free end of the sliding bracket 8, a transmission belt 9 is arranged on one side of the bracket part, and a transmission member 901 for driving the cleaning disc 1, the pipeline part, and the driving part assembly to move along the sliding bracket 8 and a gear box 902 that acts on the driving part to achieve a transmission effect; Based on the above content, the matching structure of the cleaning disc 1 and the pipeline part enables the cleaning disc 1 to rotate by itself, and the rotational movement will not drive the external water supply pipeline to produce synchronous movement, thereby avoiding the water supply blockage caused by the large-scale movement of the external water supply pipe, and the structure is easy to realize a large-area, rotating, and circulating scrubbing structure, thereby improving the cleaning effect; the matching structure of the pipeline part and the driving part enables the cleaning disc 1 to rotate by itself and to rotate in a circle, thereby further increasing the cleaning area and scrubbing effect, and is conducive to improving the cleaning effect of stubborn ink; Furthermore, a scrubbing cloth is provided on the outer periphery of the upper end of the cleaning disc 1, and the water circulation function of the cleaning disc 1 continuously circulates and cleans the scrubbing cloth, while the scrubbing cloth contacts the nozzle of the printing press for cleaning; Further, bristles are inserted into the upper end surface of the cleaning disc 1, and the water circulation function of the cleaning disc 1 continuously circulates and cleans the bristles, while the bristle printer nozzle contacts and cleans; Furthermore, a sealing gasket is rotatably abutted between the first pipeline 2 and the connection port 102 .

[0020] Reference Figure 3-9 Here is an example of the connection structure between the cleaning plate 1 and the pipeline part: In order to realize the rotation connection between the cleaning disk 1 and the pipeline part, a first rotating ring 3 is sleeved on the periphery of the connecting port 102, an annular rotating groove 301 is opened inside the first rotating ring 3, a second rotating ring 4 is rotatably installed inside the rotating groove 301, and the inner end face of the second rotating ring 4 is threadedly connected with the outer end face of the connecting port 102. The outer end face of the first pipeline 2 is integrally formed with a limiting ring 202 that is useful for abutting against the first rotating ring 3 and the connecting port 102. The combined effect of the above structure is referred to Fig. 9 The enlarged part of area B in the figure; Furthermore, in order to reduce friction resistance, multiple sets of ball structures are rotatably mounted on both upper and lower end surfaces of the limit ring 202; Furthermore, a positioning protrusion 104 and a positioning groove 302 are respectively provided on the inner end surface of the first rotating ring 3 and the outer end surface of the connection port 102, so that the first rotating ring 3 and the connection port 102 cannot rotate after being assembled in place. The overall installation method is to insert the connection port 102 into the first rotating ring 3 and connect the positioning protrusion 104 and the positioning groove 302 in place, and the lower end of the connection port 102 abuts against the limit ring 202. At this time, the second rotating ring 4 is rotated to be threadedly connected to the connection port 102 to complete the assembly; For further reference, Figure 4 A window communicating with the rotating groove 301 is provided on the outer end surface of the first rotating ring 3 for moving the second rotating ring 4 from the outside.

[0021] Reference Figure 6-9 Here is an example of the transmission structure implementation of the pipeline part and the drive part: The third rotating ring 5 is sleeved on the outer periphery of the lower end of the first rotating ring 3, and the outer periphery end surface of the third rotating ring 5 is provided with a first meshing groove 502 for meshing and transmitting with the second meshing groove 601. In order to further improve the cleaning effect, the outer periphery end surface of the third rotating ring 5 is provided with multiple groups of locking grooves 503, and the outer periphery of the fourth rotating ring 6 is provided with multiple groups of placement grooves 602, and the inner part of the placement groove 602 is elastically installed with a locking part 603, and one end of the locking part 603 is movably plugged with the locking groove 503, and one end of the fifth rotating ring 7 is circumferentially provided with multiple groups of permanent magnets 701 cooperating with the locking part 603; Based on the above content, when the placement groove 602 provided on the fourth rotating ring 6 rotates to the position of the permanent magnet 701 installed on the fifth rotating ring 7, the permanent magnet 701 magnetically attracts the locking part 603 to generate displacement. At this time, the locking part 603 is disengaged from the locking groove 503, and the third rotating ring 5 and the fourth rotating ring 6 are released from the locking relationship. At this time, the fourth rotating ring 6 will drive the cleaning disk 1 to rotate along the connection between itself and the first pipeline 2 when rotating; when the placement groove 602 provided on the fourth rotating ring 6 is away from the position of the permanent magnet 701 installed on the fifth rotating ring 7, the locking part 603 returns to its position. At this time, the locking part 603 contacts the locking groove 503, and periodically drives the cleaning disk 1 to rotate along the lower end of the first pipeline 2; therefore, the above structure enables the cleaning disk 1 to have two rotation modes; Furthermore, due to the non-negligible friction between objects, when the connection between the first pipeline 2 and the cleaning disc 1 and the lower end of the first pipeline 2 are both free ends, when the fourth rotating ring 6 rotates, it can always drive the cleaning disc 1 to rotate on its own and in a circular motion; Furthermore, the permanent magnet 701 may be replaced with a ring-shaped electromagnet, and the magnetic force of the electromagnet may be controlled by current to change the state of the locking portion 603; Furthermore, a plug-in port 501 for fixing is provided inside the third rotating ring 5, and a plug-in rod 303 which can be plugged into the plug-in port 501 is integrally formed at the lower end of the first rotating ring 3 to play a plug-in fixing role.

[0022] Reference Fig. 9 Here is an example of the connection structure between the pipeline part and the bracket part: The lower end of the first pipeline 2 is rotatably sleeved with the second pipeline 201, and the lower end of the second pipeline 201 is provided with a pipeline port 203 which is connected to the inner and outer groups of the second pipelines 201 respectively. The pipeline port 203 is used to connect external water supply and water suction pipelines. The mounting bracket 801 is fixedly connected to the outer end face of the second pipeline 201, and the second pipeline 201 and the first pipeline 2 have the same inner and outer outer mounting structure.

[0023] Last addition: In order to realize the rotation effect of the transmission belt 9 on the fourth rotating ring 6, a group of transmission parts 901 should be slidably sleeved with the transmission belt 9, and a pulley that can mesh with the convex teeth on the transmission belt 9 should be rotatably installed inside the transmission part 901. The pulley is connected to the input end of the gear box 902, and the output end of the gear box 902 is transmission-installed with a worm. The second meshing groove 601 opened on the outer end surface of the fourth rotating ring 6 is a worm gear tooth structure. At this time, a worm gear transmission structure can be formed. Refer to Figure 1 There are two groups of transmission members 901, one of which is fixed to the transmission belt 9, and the other is slidably sleeved with the transmission belt 9. The transmission member 901 fixed to the transmission belt 9 is used to drive the cleaning disc 1, the pipeline part, and the driving part assembly to move along the sliding bracket 8; A filter, a heater and other devices may also be installed at the pipeline port 203 to increase the water temperature and water quality, reduce scratches on the printer nozzle caused by particulate matter, and the heated water temperature may also facilitate the cleaning of ink.

[0024] Based on the above-mentioned embodiments, when assembling: Insert the connection port 102 of the cleaning disk 1 into the interior of the first rotating ring 3, and make the positioning groove 302 and the positioning protrusion 104 be inserted and positioned, and the lower end of the connection port 102 abuts against the limit ring 202, and then the second rotating ring 4 can be rotated, and the second rotating ring 4 is threadedly connected with the connection port 102, and finally the limit ring 202 is placed between the connection port 102 and the first rotating ring 3. It should be noted that the second rotating ring 4 cannot be rotated too tight to avoid locking the limit ring 202; The first pipeline 2 is rotatably connected to the second pipeline 201, and the second pipeline 201 is fixed to the mounting bracket 801, and the fourth swivel 6 and the fifth swivel 7 combination is sleeved on the outer periphery of the third swivel 5, and then the third swivel 5 is plugged and fixed to the first swivel 3, and the fourth swivel 6 and the fifth swivel 7 combination is fixed to the free end of the sliding bracket 8 by bolts or the like to complete the main assembly; During use, the attachments on the upper surface of the cleaning plate 1 can be changed according to needs, and a scrubbing cloth or a soft brush can be set to assist in cleaning.

[0025] Based on the above implementation examples, when used: Start the transmission belt 9, and a group of transmission parts 901 fixed to the transmission belt 9 will drive the cleaning disc 1, the pipeline part, and the driving part assembly to move along the sliding bracket 8. A group of transmission parts 901 slidingly matched with the transmission belt 9 drives the fourth rotating ring 6 to rotate through the gear box 902. When the fourth rotating ring 6 rotates, it can drive the cleaning disc 1 to rotate on its own or in a circular motion. The two groups of pipeline ports 203 are respectively connected to an external water supply device and a pumping device. Clean water is supplied through one group of pipeline ports 203, flows through the second pipeline 201 and the first pipeline 2 and enters a group of connecting ports 102. The clean water entering the connecting port 102 is output through the cleaning port 103 connected thereto, and then is pumped back through another group of cleaning ports 103 to achieve a water circulation cleaning effect.
