Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic cleaning equipment, specifically relating to ultrasonic cleaning equipment for surface treatment of plastic products. Background Technology

[0002] Ultrasonic cleaning equipment mainly consists of an ultrasonic generator and an ultrasonic transducer. The ultrasonic generator produces high-frequency oscillation signals, typically above 20kHz. These electrical signals are converted into mechanical vibrations by the transducer, which can quickly and effectively remove grease, dust, pigments, mold release agents, and other contaminants from the surface of plastic products. The cleaning effect is excellent, which can greatly improve production efficiency.

[0003] Traditional ultrasonic cleaning equipment typically uses a simple rectangular design for its cleaning tanks. While this standardized construction facilitates manufacturing and cost control, it reveals significant limitations when dealing with complex contaminants such as grease and dust on the surfaces of plastic products. This is because the rectangular tank inherently contains acoustic blind zones at the corners, bottom, and sidewalls. Furthermore, the complex structures of plastic products, such as snap-fit ​​seams and threaded holes, create a "shadow effect" in these areas, rendering the cavitation effect ineffective.

[0004] When plastic products with stubborn grease or optical lenses with deposited precision dust are immersed in a cleaning tank, the parallel sound waves generated by the rectangular tank struggle to penetrate the physical barrier formed by its complex contours. This is especially true for plastic parts with internal cavities or inverted structures, where the reflection and refraction of ultrasound further weakens the energy density, making it impossible for dirt hidden in corners to withstand sufficient cavitation impact. These cleaning blind spots not only increase rework rates, but residual grease can also contaminate subsequent painting processes, and dust particles can scratch high-precision plastic optical surfaces. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic cleaning device for the surface treatment of plastic products, aiming to solve the problem in existing ultrasonic cleaning devices where, when plastic products with stubborn grease or optical lenses with deposited precision dust are immersed in the cleaning tank, the parallel sound waves generated by the rectangular tank are difficult to penetrate the physical barrier formed by the complex contours. Especially for plastic parts with internal cavities or inverted structures, the reflection and refraction of ultrasonic waves further weaken the energy density, making it impossible for dirt hidden in dead corners to withstand sufficient cavitation impact. This cleaning blind spot not only increases the rework rate, but residual grease may contaminate subsequent spraying processes, and dust particles can scratch high-precision plastic optical surfaces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning device for surface treatment of plastic products, comprising an ultrasonic cleaner and an ultrasonic generator controller mounted on one side of the ultrasonic cleaner, wherein a waterproof valve is mounted on the outer side wall of the ultrasonic cleaner;

[0007] A drive motor is connected to the opening on the inner wall of the ultrasonic cleaner. A mounting plate is connected to the bottom of the drive motor. Mounting screws are connected to the surface of the mounting plate. A fan blade is connected to the output end of the drive motor. A protective cover is installed on the inner wall of the ultrasonic cleaner near the fan blade.

[0008] To facilitate ultrasonic cleaning of plastic products, the preferred ultrasonic cleaning equipment for surface treatment of plastic products according to this utility model has a cover plate connected to the top of the ultrasonic cleaner, a holding rack connected inside the ultrasonic cleaner, and a bottom support plate installed on the inner wall of the ultrasonic cleaner.

[0009] To facilitate quick assembly of the drive motor, in the preferred embodiment of the ultrasonic cleaning equipment for surface treatment of plastic products according to this utility model, the drive motor is electrically connected to the ultrasonic cleaner, and the mounting screws pass through the mounting plate and are threadedly connected to the ultrasonic cleaner.

[0010] In order to improve the cleaning effect of dirt on the surface of plastic products, the ultrasonic cleaning equipment for surface treatment of plastic products of this utility model is preferably provided in which the output shaft of the drive motor is sealed to the opening of the inner wall of the ultrasonic cleaner through a sealed bearing, and the surface of the protective cover is provided with water seepage holes.

[0011] To facilitate quick assembly of the cover plate, in the preferred embodiment of the ultrasonic cleaning equipment for surface treatment of plastic products according to this utility model, the cover plate is connected to both sides with mating blocks, and the ultrasonic cleaner is connected to a mating seat on the side near the mating blocks, and the mating blocks and the mating seat are fitted together.

[0012] To facilitate stable installation of the cover plate, in the preferred embodiment of the ultrasonic cleaning equipment for surface treatment of plastic products according to this utility model, a positioning spring is connected to the opening of the inner wall of the docking seat, and a positioning buckle is connected to the other end of the positioning spring. A positioning groove is provided on the side of the docking block near the positioning buckle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves installing a mounting plate at the bottom of the drive motor at the opening on the inner wall of the ultrasonic cleaner, while placing the fan blades inside the protective cover. When the ultrasonic cleaner is started to clean the plastic products placed inside the rack, the drive motor runs, causing the fan blades to rotate. This causes the cleaning fluid inside the ultrasonic cleaner to vortex and rotate, which in turn causes the water flow to form a complex and uniform flow path. This allows the ultrasonic energy to be distributed more evenly in the cleaning tank, reducing cleaning dead corners and improving the removal effect of dirt from the surface of the plastic products.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 The present invention provides the following technical solution: an ultrasonic cleaning device for surface treatment of plastic products, including an ultrasonic cleaner 1 and an ultrasonic generator controller 2 installed on one side surface of the ultrasonic cleaner 1, and a waterproof valve 3 installed on the outer side wall of the ultrasonic cleaner 1.

[0025] An ultrasonic cleaner 1 has a drive motor 6 connected to the opening on its inner wall. A mounting plate 7 is connected to the bottom of the drive motor 6. Mounting screws 8 are connected to the surface of the mounting plate 7. A fan blade 9 is connected to the output end of the drive motor 6. A protective cover 10 is installed on the inner wall of the ultrasonic cleaner 1 near the fan blade 9.

[0026] Preferably, the top of the ultrasonic cleaner 1 is connected to a cover plate 4, the inside of the ultrasonic cleaner 1 is connected to a holding rack 5, and the inner wall of the ultrasonic cleaner 1 is installed with a bottom support plate 101.

[0027] Preferably, the drive motor 6 is electrically connected to the ultrasonic cleaner 1, and the mounting screw 8 passes through the mounting plate 7 and is threadedly connected to the ultrasonic cleaner 1. In actual use, by quickly assembling the drive motor 6 inside the ultrasonic cleaner 1, it is easy to create eddies inside the ultrasonic cleaner 1 with the fan blades 9, thereby improving the cleaning quality.

[0028] Preferably, the output shaft of the drive motor 6 is sealed to the opening in the inner wall of the ultrasonic cleaner 1 via a sealed bearing, and the surface of the protective cover 10 is provided with water seepage holes. In actual use, the use of a sealed bearing ensures the safe operation of the drive motor 6, avoids seepage, and guarantees the normal operation of the drive motor 6.

[0029] Preferably, the cover plate 4 is connected to both sides with mating blocks 11, and the ultrasonic cleaner 1 is connected to a mating seat 12 on the side near the mating blocks 11. The mating blocks 11 and the mating seats 12 are fitted together. In actual use, by fitting the mating blocks 11 and the mating seats 12 together, the cover plate 4 can be quickly assembled, avoiding the phenomenon of falling off during the surface treatment of plastic products and improving the cleaning effect.

[0030] Preferably, a positioning spring 13 is connected to the opening on the inner wall of the docking seat 12, and a positioning buckle 14 is connected to the other end of the positioning spring 13. A positioning groove 15 is provided on the side of the docking block 11 near the positioning buckle 14. In actual use, as the cover plate 4 is closed on the surface of the ultrasonic cleaner 1, the positioning spring 13 is easily driven to reciprocate and extend, and at the same time, the positioning buckle 14 is driven to engage with the positioning groove 15 on the surface of the docking block 11, so that the cover plate 4 is closed and stable, preventing liquid splashing caused by the vibration of the cleaning fluid.

[0031] The working principle of this utility model is as follows: The mounting plate 7 at the bottom of the drive motor 6 is installed at the opening on the inner wall of the ultrasonic cleaner 1, while the fan blade 9 is placed inside the protective cover 10. When the ultrasonic cleaner 1 is started, the ultrasonic generator controller 2 on one end of the ultrasonic cleaner 1 drives the ultrasonic generator to generate high-frequency oscillation signals. These electrical signals are converted into mechanical vibrations by the transducer inside the ultrasonic cleaner 1. The mechanical vibrations propagate into the cleaning fluid, causing the cleaning fluid to form alternating dense and sparse radiation, thereby ultrasonically cleaning the plastic products placed inside the rack 5. At this time, the drive motor 6 operates, driving the fan blade 9 to rotate, which in turn causes the cleaning fluid inside the ultrasonic cleaner 1 to vortex and rotate. The complex and uniform flow path of the water flow allows the ultrasonic energy to be distributed more evenly within the cleaning tank, reducing cleaning dead zones and improving the removal of dirt from the surface of plastic products. Furthermore, by placing the cover plate 4 on the surface of the ultrasonic cleaner 1, the mating blocks 11 on both sides of the cover plate 4 engage with the mating seat 12. At this time, the positioning buckle 14 compresses the positioning spring 13. When the cover plate 4 is stably closed, the compressed positioning spring 13 returns to its original position, causing the positioning buckle 14 to engage with the positioning groove 15 on one side of the mating block 11. This ensures that the cover plate 4 is stably placed on the surface of the ultrasonic cleaner 1, preventing it from falling off or being accidentally opened during ultrasonic cleaning and preventing liquid splashing caused by the vibration of the cleaning fluid.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
