Description

Technical Field

[0001] This utility model relates to the field of cleaning and drying technology, specifically to an ultrasonic cleaning device for nozzles. Background Technology

[0002] Currently, ultrasonic nozzle cleaning devices are specifically designed for plasma cutting gun nozzles. Their purpose is to remove contaminants such as metal residue and oil that accumulate after long-term operation. These contaminants not only affect cutting accuracy but can also damage the nozzle and system. This device uses high-frequency ultrasonic vibration to form microbubbles in the cleaning fluid. These bubbles rapidly expand and close to generate shock waves, effectively stripping contaminants from the nozzle surface and interior, ensuring that the nozzle is clean and free of dirt, without compromising its original accuracy.

[0003] For example, the patent with announcement number CN116727356A discloses a ten-slot fully automatic intelligent ultrasonic cleaning equipment and method for tool processing. The tool is placed in a mesh box, and then the mesh box is placed in ten cleaning chambers by a drive mechanism. The tool is cleaned and dried by the ten slots on the ten cleaning chambers. There is no need to transfer the tool during the process, which saves a lot of manpower and material resources and greatly improves the processing efficiency of the tool.

[0004] In the aforementioned patent, the ultrasonic cleaning equipment uses a ten-tank cleaning chamber and a drive mechanism to work together to make product cleaning without the need for transfer. However, after the cleaning equipment has finished cleaning once, the impurities dissolved in the water are easily re-attached to the surface of the workpiece during the lifting process of the mesh box. Direct transfer to the next cleaning tank can easily cause secondary pollution and affect the cleaning effect.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

A drive shaft is rotatably mounted inside the side plate. A drive gear is fixedly sleeved on the drive shaft. The drive shaft and the rotating shaft are connected by a synchronous belt through a synchronous pulley set.

[0008] Furthermore, two symmetrically arranged movable blocks are fixedly connected to one side of the screen frame, and two symmetrically arranged grooves are opened on the movable rod. The grooves are connected to the cavity, and the movable blocks are slidably connected in the corresponding grooves. Two symmetrically arranged connecting plates are fixedly connected inside the cavity, and the connecting plates and the corresponding movable blocks are connected to a spring.

[0009] Furthermore, the drying chamber is fixedly connected to the main body of the device, a dryer is installed on one side of the drying chamber, and two sets of symmetrically arranged grilles are provided on the drying chamber. The air outlet of the dryer is connected to one of the grilles.

[0022] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] like Figure 1-5As shown, this application provides a nozzle ultrasonic cleaning device, including a device body 1 and a drying chamber 3. The device body 1 is provided with a cleaning chamber, and a fixed rack 9 is fixedly installed inside the cleaning chamber. Two symmetrically arranged electric guide rail assemblies 6 are installed inside the cleaning chamber. Each set of electric guide rail assemblies 6 is equipped with a movable rod 7. The movable rod 7 is adapted to be driven by the electric guide rail assembly to move vertically or horizontally upward. The two movable rods 7 are movably connected to a screen frame 12. A water tank 5 is fixedly installed on the device body 1. A spray rod 8 is movably connected to the movable rod 7. A water pipe is connected between the spray rod 8 and the water tank 5. The spray rod 8 is provided with a plurality of water outlet holes arranged in a row at equal intervals.

[0024] The electric guide rail assembly 6 can have the following structure: a vertical electric guide rail and a horizontal electric guide rail. The vertical electric guide rail is mounted on the horizontal slider of the corresponding horizontal electric guide rail, and the movable rod 7 is mounted on the vertical slider of the vertical electric guide rail.

[0025] Both vertical and horizontal electric guide rails are existing technologies, mainly consisting of a base, a slider, a lead screw and nut pair, and a drive motor. The lead screw of the lead screw and nut pair is connected to the drive motor, the nut of the lead screw and nut pair is connected to the slider, and the lead screw is rotatably connected to the base.

[0026] One of the movable rods 7 is a mounting rod. The mounting rod has a cavity inside, and a support rod 13 is rotatably mounted inside the cavity. The support rod 13 is fixedly connected to the spray rod 8. A transmission gear 14 is rotatably mounted on the outer circumference of the support rod 13. A rotating shaft 22 is rotatably mounted inside the cavity. A turntable 18 and a cam 20 are fixedly sleeved on the outer circumference of the rotating shaft 22. A sliding rack 15 is slidably arranged inside the cavity. The sliding rack 15 and the turntable 18 are movably hinged together by a crank rod 17. The sliding rack 15 is meshed with the transmission gear 14. A side plate 10 is fixedly mounted on one side of the mounting rod. A drive shaft 25 is rotatably mounted inside the side plate 10. A drive gear 26 is fixedly sleeved on the drive shaft 25. The drive shaft 25 and the rotating shaft 22 are connected by a synchronous belt 21 through a synchronous pulley set.

[0027] like Figure 1-5 As shown, two symmetrically arranged movable blocks 19 are fixedly connected to one side of the screen frame 12. Two symmetrically arranged grooves are opened on the movable rod 7. The grooves are connected to the cavity. The movable blocks 19 are slidably connected in the corresponding grooves. Two symmetrically arranged connecting plates 23 are fixedly connected inside the cavity. The connecting plates 23 and the corresponding movable blocks 19 are connected together by a spring 24.

[0028] like Figure 1-5As shown, the drying chamber 3 is fixedly connected to the device body 1. A dryer 2 is installed on one side of the drying chamber 3. Two sets of symmetrically arranged grilles 11 are opened on the drying chamber 3. The air outlet of the dryer 2 is connected to one of the grilles 11. A straight groove 16 is opened inside the cavity. A sliding rack 15 is slidably connected inside the straight groove 16. A transmission groove is opened inside the side plate 10. The transmission groove is connected to the cavity. The synchronous belt 21 is located inside both the transmission groove and the cavity.

[0029] The working principle of this utility model is as follows: This device is used to clean the nozzles on a plasma cutting gun. During cleaning, the nozzles are first placed inside the sieve frame 12. Then, the cleaning device is connected to the power supply and started. The vertical electric guide rail simultaneously drives the two movable rods 7 and the sieve frame 12 to move. The sieve frame 12 moves vertically downward and is immersed in the cleaning chamber filled with cleaning fluid. Inside the cleaning chamber, the high-frequency vibration generated by the ultrasonic generator acts on the cleaning fluid, forming microbubbles that rapidly expand and close, generating impact force to peel off the dirt on the nozzle surface, achieving deep cleaning.

[0030] After a period of ultrasonic cleaning, the screen frame 12 rises under the drive of the vertical electric guide rail. The drive gear 26 moves upward along with the side plate 10. After the screen frame 12 is completely separated from the cleaning liquid, the drive gear 26 moves to the side of the fixed rack 9 and meshes with it. The drive gear 26 rotates and drives the drive shaft 25 and the synchronous belt 21 to rotate together. The rotating shaft 22, the turntable 18 and the cam 20 also rotate. The cam 20 rotates and pushes the movable block 19 located on its side. The movable block 19 drives the screen frame 12 to move back and forth. The nozzles inside the screen frame 12 also vibrate, which promotes the removal of dirt.

[0031] Furthermore, the crank 17, which is movably hinged on the turntable 18, moves together with the turntable 18 and drives the sliding rack 15 to move back and forth, thereby causing the transmission gear 14 and the support rod 13 to rotate back and forth. A pump is installed between the water tank 5 and the spray bar 8. The pump introduces the clean cleaning liquid in the water tank 5 into the spray bar 8 through the pipe and sprays it onto the nozzles in the screen frame 12. This effectively washes away the dirt particles that are peeled off and suspended in the cleaning liquid during the ultrasonic vibration. At the same time, it can further clean away the dirt that has been dissolved in the cleaning liquid in the cleaning chamber, reducing the risk of secondary pollution. This ensures the cleanliness of the nozzles after cleaning and avoids the problem of incomplete cleaning requiring manual intervention, providing good conditions for subsequent drying.

[0032] Finally, the screen frame 12 moves into the drying chamber 3 under the drive of the horizontal electric guide rail. The dryer 2 starts and blows out hot air, which is then evenly sent into the screen frame 12 through the grille 11 to dry the nozzles. After drying, the nozzles have completed the entire cleaning process, and then the staff takes them out.

[0033] In addition, the cleaning chamber needs to be cleaned after a period of use. First, the cleaning liquid and stains are drained through the drain pipe on one side of the cleaning chamber. Then, the cleaning chamber is rinsed. Opening the chamber door 4 can further improve the cleaning efficiency. It should be noted that during the drying process, the nozzle will drip cleaning liquid. This cleaning liquid will flow out smoothly through the drain pipe on one side of the cleaning chamber. In order to facilitate the discharge of the cleaning liquid, the interior of the cleaning chamber is set to be inclined.

[0034] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
