[0029] In this embodiment, by starting the slider 3 , the slider drives the scraper 14 to move left and right on the transverse movement assembly 5 .

[0030] Existing screen printing machines lack cleaning equipment. After printing, the screen will adhere to a lot of ink. If it is not cleaned in time, the ink adhered to the screen will dry up. The dried ink is not only difficult to clean, but may also cause permanent damage to the screen, affecting the service life of the screen and the printing effect. To solve the above technical problems, please refer to Figure 1-5 As shown,

[0031] The bracket 6 is provided with a hydraulic cylinder 13, which is a HOBRD6310025LB+Y series hydraulic cylinder. The protruding end of the hydraulic cylinder 13 extends out of the bracket 6 and is fixedly provided with a scraper 14. When the hydraulic cylinder 13 is activated, the protruding end of the hydraulic cylinder 13 extends out, thereby driving the scraper 14 to move longitudinally.

[0032] A frame is fixedly installed on the side end face of the bracket 6 by fastening screws, and an air jet end 8 is provided on the frame. The air jet end 8 includes an air inlet port 081 for inputting the gas, and the air inlet port 081 is connected to the air supply system (not annotated in the figure). The air supply system can use common equipment on the market and will not be described in detail here.

[0033] In this embodiment, by starting the gas supply system, the gas can be delivered to the air injection end 8 through the air inlet port 081 and output through the air injection end 8.

[0034] Furthermore, a water tank 7 is provided on the end face of the slider 3 away from the transverse movement assembly 5, and the water tank 7 and the slider 3 are detachably connected. The water outlet of the water tank 7 is connected to the pipeline, and is connected to the nozzle 9 through the pipeline, and a control valve is provided on the pipeline.

[0035] Furthermore, the nozzle 9 includes a sleeve 091, a groove body for the adjustment ring 12 to extend into is provided on the sleeve 091, and at least one set of connecting rods 092 is provided on the outer wall of the adjustment ring extending into the sleeve 091, and the base of the water inlet 093 is connected through the connecting rod 092, the outer wall of the base of the water inlet 093 conflicts with the inner wall of the sleeve 091, and an external thread is provided on the outer wall of the top seat of the water inlet 093, which is used in conjunction with the internal thread of the sleeve 091 for spiral transmission.

[0036] In this embodiment, the water inlet 093 can be driven to rotate by rotating the adjustment ring 12.

[0037] Furthermore, a baffle 095 is provided on the top seat of the water inlet 093 away from the position of the connecting rod 092 and is integrated therewith, and the baffle 095 is provided in a semicircular shape, and an outlet end is provided on the top seat of the water inlet 093 near the position of the baffle 095.

[0038] Furthermore, a spiral water guide 094 is provided on the inner wall of the water inlet 093. The spiral water guide 094 is provided to guide the water so that the water flows out through the outlet end of the top seat of the water inlet 093.

[0039] Furthermore, the nozzle 9 also includes a nozzle outlet 097, and a spray plate 096 is installed in the nozzle housing near the nozzle outlet 097, the spray plate 096 is provided with an arc-shaped water outlet groove 091, and a blocking plate 098 is installed at the end of the nozzle outlet 097, the blocking plate 098 is provided with a water outlet hole with a diameter of 0.2 mm, and an elastic sealing piece 099 is provided on the side of the blocking plate 098 away from the spray plate, and the elastic sealing piece 099 is provided with multiple groups of rectangular grooves 0991, and the elastic sealing piece 099 is divided into multiple groups of sectors by the multiple groups of rectangular grooves 0991.

[0040] In this embodiment, by rotating the adjustment ring 12, the baffle 095 on the water inlet 093 can be driven to rotate, and then the water outlet area of ​​the water outlet groove 0961 on the spray plate 096 can be adjusted, so that when the water flows through the water outlet groove 0961, it can be sprayed out in a high-pressure manner, thereby reducing the risk of blockage of the elastic sealing piece 099 at the nozzle outlet 097.

[0041] The utility model adds an elastic blocking piece 099 and uses it in conjunction with a blocking plate 098 with a hole diameter of 0.2mm, so that the water flow first passes through the narrow water outlet with a hole diameter of 0.2mm, so that the water flow is sprayed out at high pressure. In addition, multiple groups of rectangular grooves 0991 are formed on the elastic blocking piece 099, and the elastic blocking piece 099 is divided into multiple groups of fan shapes by the multiple groups of rectangular grooves 0991, thereby ensuring that the high-pressure water flow is sprayed out at multiple angles, thereby increasing the water flow coverage area.

[0042] The use process and working principle of this utility model:

[0043] When the utility model is in use, after completing the printing task, first connect the pipe group, then open the control valve set on the pipeline, so that water flows into the nozzle 9 and is sprayed out through the nozzle 9 to clean the screen. After the cleaning is completed, close the control valve, and then start the air supply system to transport the gas to the jet end 8 through the air inlet port 081 and output it through the jet end 8 to blow dry the water on the screen.

[0044] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to be limiting.
