Therefore, we propose a spray gun nozzle cleaning device to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a spray gun nozzle cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spray gun nozzle cleaning device includes: a base plate, an inlet pipe connected to the interior of the base plate, a cavity connected to the top of the inlet pipe, a housing on one side of the cavity, a rotating shaft rotatably mounted inside the housing, a worm gear fixedly mounted on the outer side of the rotating shaft, a turntable fixedly mounted on one side of the rotating shaft, a lead screw rotatably mounted inside the housing, a worm wheel fixedly mounted on the outer side of the lead screw rotatably mounted, a moving block threadedly connected to the outer side of the lead screw rotatably mounted, a throttling rod fixedly mounted on one side of the moving block, an outlet pipe connected to one side of the cavity, a throttling valve and a ring fixedly mounted inside the outlet pipe, a circular rotating ring rotatably mounted inside the circular ring, multiple sets of fan blades fixedly mounted inside the circular rotating ring, and a cleaning brush fixedly mounted on one side of the circular rotating ring.

[0008] Preferably, a frame is fixedly installed on the top of the base plate, a motor is fixedly installed on the top of the frame, a lead screw is fixedly installed on the output end of the motor, two sets of movable plates are threadedly connected to the outer side of the lead screw, and a clamp is fixedly installed on one side of each set of movable plates.

[0009] Preferably, a guide rod is fixedly installed inside the housing, and the movable block is slidably installed on the outside of the guide rod.

[0010] Preferably, a limiting rod is fixedly installed between the bottom of the frame and the base plate, and two sets of movable plates are slidably installed on the outside of the limiting rod.

[0011] Preferably, the throttling rod is disposed inside the cavity, and a sealing ring is provided inside the cavity, with the throttling rod slidably installed within the sealing ring.

[0012] Preferably, the worm gear meshes with the worm.

[0013] In this utility model, a spray gun nozzle cleaning device is described. The water flow drives the fan blades and the circular rotating ring to rotate within the ring, thereby driving the cleaning brush to rotate. This achieves the goal of driving the cleaning brush to operate through the water flow. The water flow can disperse large stains, while the cleaning brush can remove stubborn attached substances. The two work together to improve the thoroughness of cleaning.

[0014] In this utility model, a spray gun nozzle cleaning device is provided. A motor drives a lead screw to rotate, which in turn drives a moving plate to move relative to each other under the restriction of a limit rod. This causes the clamps to move relative to each other, thereby clamping the nozzle. Through clamping, the position and posture of the clamps can be kept relatively fixed during each cleaning, thus ensuring a high degree of consistency in cleaning conditions and effects.

[0015] This utility model has a reasonable structural design. By setting a turntable to drive the rotating shaft and worm gear to rotate, it drives the worm wheel and lead screw two to rotate. By setting a moving block and a throttling rod, the moving block drives the throttling rod to move under the guidance of lead screw two and guide rod, thereby regulating the water flow through the throttling valve in the cavity. The impact force of the water flow combined with the physical wiping of the cleaning brush can more comprehensively and deeply remove dirt from the nozzle. The water flow can break up large stains, while the cleaning brush can remove stubborn attached substances. The synergistic effect of the two improves the thoroughness of cleaning.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A spray gun nozzle cleaning device includes: a base plate 1, an inlet pipe 7 connected to the inside of the base plate 1, a cavity 8 connected to the top of the inlet pipe 7, a box 15 disposed on one side of the cavity 8, a rotating shaft 17 rotatably mounted inside the box 15, a worm gear 18 fixedly mounted on the outside of the rotating shaft 17, a turntable 16 fixedly mounted on one side of the rotating shaft 17, a lead screw 19 rotatably mounted inside the box 15, a worm wheel 20 fixedly mounted on the outside of the lead screw 19, a moving block 21 threadedly connected to the outside of the lead screw 19, a throttling rod 22 fixedly mounted on one side of the moving block 21, an outlet pipe 9 connected to one side of the cavity 8, a throttling valve 25 and a ring 10 fixedly mounted inside the outlet pipe 9, a circular rotating ring 12 rotatably mounted inside the ring 10, multiple sets of fan blades 13 fixedly mounted inside the circular rotating ring 12, and a cleaning brush 14 fixedly mounted on one side of the circular rotating ring 12.

[0024] In this embodiment, a frame 2 is fixedly installed on the top of the base plate 1, a motor 3 is fixedly installed on the top of the frame 2, a lead screw 11 is fixedly installed at the output end of the motor 3, two sets of moving plates 4 are threaded to the outer side of the lead screw 11, and a clamp 5 is fixedly installed on one side of each set of moving plates 4. By clamping the clamp 5, the position and posture of the clamp 5 can be kept relatively fixed during each cleaning, thereby ensuring that the cleaning conditions and effects are highly consistent.

[0025] In this embodiment, a guide rod 24 is fixedly installed inside the housing 15, and a moving block 21 is slidably installed on the outside of the guide rod 24. The guide rod 24 provides a clear and precise path for the displacement of the moving block 21, enabling it to move along a predetermined straight line direction and avoiding offset and deviation during the movement process.

[0026] In this embodiment, a limiting rod 6 is fixedly installed between the bottom of the frame 2 and the base plate 1. Two sets of movable plates 4 are slidably installed on the outside of the limiting rod 6. The limiting rod 6 can precisely limit the movement range of the movable plates 4, ensuring that they move within the designed stroke, thereby achieving precise control of the cleaning position of the spray gun nozzle.

[0027] In this embodiment, the throttle rod 22 is disposed inside the cavity 8, and a sealing ring 23 is disposed inside the cavity 8. The throttle rod 22 is slidably installed inside the sealing ring 23, thereby regulating the water flow of the throttle valve 25 within the cavity 8. The impact force of the water flow combined with the physical wiping of the cleaning brush can more comprehensively and thoroughly remove dirt from the nozzle. The water flow can disperse large stains, while the cleaning brush can remove stubborn attached substances. The two work together to improve the thoroughness of cleaning.

[0028] In this embodiment, the worm gear 20 meshes with the worm 18, and the transmission between the worm gear 20 and the worm 18 has high transmission accuracy, enabling fine and precise adjustment of the water flow.

[0029] In this embodiment, during use, the nozzle is placed between the clamps 5, and the motor 3 is started to drive the lead screw 11 to rotate, thereby causing the moving plate 4 to move relative to the limiting rod 6, which in turn causes the clamps 5 to clamp the nozzle. Through the clamping of the clamps 5, the position and orientation of the clamps 5 can remain relatively fixed during each cleaning, thus ensuring a high degree of consistency in cleaning conditions and effects. Rotating the turntable 16 drives the rotating shaft 17 and the worm gear 18 to rotate, which in turn drives the worm wheel 20 and the lead screw 19 to rotate, thereby causing the moving block 21 and the throttling rod 22 to move on the guide rod 24. The throttling rod 22 moves via the lead screw 19. The adjustment of the outlet between 22 and throttle valve 25 regulates the water flow, thereby adjusting the water flow size during the cleaning process. Different types, specifications, or degrees of contamination of the spray gun nozzles may require different water flow intensities to achieve the ideal cleaning effect. By setting a closed ring 23 to prevent water leakage, when the water flows through the outlet, due to the inclined setting of the fan blade 13, the impact force of the water flow drives the fan blade 13 and the circular rotating ring 12 to rotate within the ring 10, thereby driving the cleaning brush 14 to rotate, thus cleaning the nozzle. The water flow can disperse large stains, while the cleaning brush can remove stubborn attached substances. The two work together to improve the thoroughness of cleaning.

[0030] The above provides a detailed description of the spray gun nozzle cleaning device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
