Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning technology, specifically a cleaning chamber and ultrasonic cleaning equipment. Background Technology

[0002] Ultrasonic cleaning equipment utilizes the cavitation effect, acceleration effect, and direct flow effect of ultrasound in liquids to directly and indirectly act on liquids and dirt, causing the dirt layer to be dispersed, emulsified, and peeled off to achieve the purpose of cleaning. Ultrasonic waves form tiny bubbles in the liquid, and when the bubbles burst, they release energy, generating violent shock waves and eddies, which peel off dirt from the surface of objects.

[0003] Most ultrasonic cleaning equipment currently in use lacks a positioning and adjustment structure, making it difficult to accurately adjust the position of the material feeding box within the cleaning chamber. For products of different sizes and shapes, it is impossible to accurately place the material feeding box in the most suitable position for ultrasonic cleaning, which may affect the cleaning effect. Furthermore, the ultrasonic transducer is generally fixed inside the equipment, resulting in a fixed ultrasonic propagation range, which also affects the ultrasonic cleaning effect. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning chamber and an ultrasonic cleaning device to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning chamber, comprising a chamber body, a material feeding cage, side support arms, and ultrasonic transducers. A chamber cover is provided on the top of the chamber body, and an ultrasonic generator is connected to the outside of the chamber body. An electric telescopic rod is provided on the top of the chamber cover. A positioning mechanism is provided inside the chamber body. The positioning mechanism adjusts the installation height of the side support arms according to the specifications of the material feeding cage to meet the immersion cleaning treatment of workpieces of different specifications. A cleaning mechanism is provided at the inner end of the chamber cover. The cleaning mechanism adjusts the height of the ultrasonic transducers and the distance between the two sets of ultrasonic transducers according to the cleaning requirements and the height of the material feeding cage, so as to avoid the ultrasonic transducers being too close, which would weaken the cavitation effect, or too far, which would reduce the cleaning efficiency.

[0006] As a preferred technical solution, the positioning mechanism includes a material feeding cage, side support arms, guide blocks, screws, and nuts. The material feeding cage is located inside the silo body. Side support arms are symmetrically arranged inside the silo body. Guide blocks are welded to the outer sides of the side support arms. Screws are symmetrically connected through the outer sides of the guide blocks. The bottom end of the screw is connected to the inner end of the silo body. Nuts are threadedly connected to the outer side of the screw. Nuts are arranged parallel to the bottom of the guide blocks.

[0007] As a preferred technical solution, the hopper body is connected to the guide block through symmetrically opened grooves inside, and the hopper body is connected to the guide block through symmetrically arranged screws.

[0008] As a preferred technical solution, the material feeding cage is connected to the guide block through side support arms symmetrically arranged on both sides.

[0009] As a preferred technical solution, the cleaning mechanism includes a bracket, an ultrasonic transducer, a linear guide rail, a slider, and fasteners. The bracket is located at the inner end of the compartment cover, and the linear guide rail is located directly below the bracket. The slider is connected to the outer side of the linear guide rail, and the ultrasonic transducer is connected to the bottom end of the slider. The linear guide rail is connected through a fastener, and the tail end of the fastener is connected to the outer side of the slider.

[0010] As a preferred technical solution, the linear guide rail is connected to the top of the ultrasonic transducer via a slider at the bottom. The distance between the two sets of ultrasonic transducers is less than the width of the material feeding box. The ultrasonic transducer and the ultrasonic generator are connected by wires.

[0011] As a preferred technical solution, the bracket is connected to the top of the compartment cover via an electric telescopic rod connected to the top.

[0012] As a preferred technical solution, an ultrasonic cleaning device includes the aforementioned cleaning chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides lateral support to the material storage basket through the side support arm. The guide block cooperates with the groove opened inside the basket to provide stable lateral positioning for the material storage basket. Rotating the nut causes the guide block to move up and down along the screw, thereby driving the side support arm and the material storage basket to adjust to the appropriate height and position. This positioning method ensures that the material storage basket will not easily shake or shift during the cleaning process, ensuring the stability of the product during cleaning and avoiding damage caused by the product colliding with each other due to shaking. It is especially suitable for cleaning some precision and fragile products.

[0014] 2. This utility model connects the ultrasonic generator to the bin cover via a bracket and an electric telescopic rod, enabling the ultrasonic generator to be raised and lowered vertically. During cleaning, the ultrasonic generator descends, bringing it closer to the material feeding bin, thus enhancing the efficiency of ultrasonic energy transmission and improving the cleaning effect. The layout of the ultrasonic generators can be flexibly adjusted according to the width of the material feeding bin, since the spacing between the ultrasonic generators is known to be less than the width of the bin, ensuring that the ultrasonic waves cover the entire bin area and avoiding blind spots in the cleaning process.

[0017] 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.

[0018] Example: Figures 1 to 5 As shown, this utility model provides the following technical solution: a cleaning chamber, including a chamber body 1, a material feeding net box 6, side support arms 7, and an ultrasonic transducer 13. A chamber cover 2 is provided on the top of the chamber body 1. An ultrasonic generator 3 is connected to the outside of the chamber body 1. An electric telescopic rod 4 is provided on the top of the chamber cover 2. A positioning mechanism 5 is provided inside the chamber body 1. The positioning mechanism 5 adjusts the installation height of the side support arms 7 according to the specifications of the material feeding net box 6 to meet the immersion cleaning treatment of workpieces of different specifications. A cleaning mechanism 11 is provided at the inner end of the chamber cover 2. The cleaning mechanism 11 adjusts the height of the ultrasonic transducer 13 and the distance between the two sets of ultrasonic transducers 13 according to the cleaning requirements and the height of the material feeding net box 6, so as to avoid the ultrasonic transducers 13 being too close, which would weaken the cavitation effect, or too far, which would reduce the cleaning efficiency.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, the positioning mechanism 5 includes a material feeding mesh box 6, side support arms 7, guide blocks 8, screws 9, and nuts 10. The material feeding mesh box 6 is located inside the hopper body 1. The side support arms 7 are symmetrically arranged inside the hopper body 1. Guide blocks 8 are welded to the outer side of the side support arms 7. Screws 9 are symmetrically connected through the outer side of the guide blocks 8. The bottom end of the screws 9 is connected to the inner end of the hopper body 1. Nuts 10 are threadedly connected to the outer side of the screws 9. Nuts 10 are arranged parallel to the lower part of the guide blocks 8. The hopper body 1 is connected to the guide blocks 8 through symmetrically opened grooves inside. The hopper body 1 is connected to the guide blocks 8 through symmetrically arranged screws 9. The material feeding mesh box 6 is connected to the guide blocks 8 through symmetrically arranged side support arms 7 on both sides.

[0020] Specifically, the position of the guide block 8 can be precisely adjusted through the cooperation of the screw 9 and the nut 10. When it is necessary to clean products of different sizes, shapes, or placement requirements, the nut 10 can be rotated to move the guide block 8 up and down along the screw 9, thereby driving the side support arm 7 and the material feeding box 6 to adjust to the appropriate height and position to meet diverse cleaning needs, ensure that the products in the material feeding box 6 are in the optimal position for ultrasonic cleaning, and improve the cleaning effect.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning mechanism 11 includes a bracket 12, an ultrasonic transducer 13, a linear guide rail 14, a slider 15, and a fastener 16. The bracket 12 is located at the inner end of the bin cover 2. The linear guide rail 14 is located directly below the bracket 12. The slider 15 is connected to the outer side of the linear guide rail 14. The ultrasonic transducer 13 is connected to the bottom end of the slider 15. The fastener 16 is connected through the linear guide rail 14. The tail end of the fastener 16 is connected to the outer side of the slider 15. The linear guide rail 14 is connected to the top end of the ultrasonic transducer 13 through the slider 15 located at the bottom end. The distance between the two sets of ultrasonic transducers 13 is less than the width of the material feeding box 6. The ultrasonic transducer 13 is connected to the ultrasonic generator 3 by wires. The bracket 12 is connected to the top end of the bin cover 2 through an electric telescopic rod 4 connected to the top end.

[0022] Among them, the spacing and position of multiple ultrasonic transducers 13 can be adjusted by linear guide rails 14 to ensure that the sound waves form a uniform coverage area inside the material feeding box 6, avoiding excessive local energy that could damage the product or insufficient cleaning due to weak local energy. To clean workpieces of different specifications, the fasteners 16 can be loosened and the sliders 15 can be slid to reposition the ultrasonic transducers 13, or the overall height can be adjusted by raising and lowering the electric telescopic rod 4. During maintenance, the bracket 12 can be raised directly to facilitate the removal of the material feeding box 6 or the replacement of the ultrasonic transducers 13.

[0023] The working principle of this utility model is as follows: The interior of the bin 1 is symmetrically equipped with grooves that connect to the guide blocks 8. The screw 9 passes through the guide blocks 8 and connects to the inner end of the bin 1. The operator places the guide blocks 8 into the bin 1 along the grooves, then passes the screw 9 through the guide blocks 8 and connects it to the bin 1. Finally, the nut 10 is installed to complete the initial installation of the positioning mechanism 5. During use, by rotating the nut 10, the height of the top of the guide blocks 8 on both sides can be adjusted by the two sets of nuts 10. In this way, the cleaning depth of the material feeding box 6 can be controlled according to the size of the feeding box 6 and the specifications of the workpiece, so as to ensure that the cleaning fluid and hydrocarbon solvent immerse the workpiece in cleaning. During the cleaning process, the operator adds hydrocarbon solvent to the interior of chamber 1 in a specific ratio. The high-frequency AC signal generated by the ultrasonic generator 3 is transmitted to the ultrasonic transducer 13 through wires. The ultrasonic transducer 13 vibrates through piezoelectric ceramics. Piezoelectric ceramics have a special piezoelectric effect. When a high-frequency electric field is applied to its two ends, i.e., the high-frequency AC signal output by the ultrasonic generator 3, the piezoelectric ceramics will undergo mechanical deformation as the electric field changes. The reverse energy can be absorbed through the back plate inside the ultrasonic transducer 13, reducing energy loss, while the radiation plate effectively transmits the vibration to the surrounding medium, causing the medium to produce alternating compression and sparsity fluctuations, forming ultrasonic waves. At the same time, it makes it easier for the hydrocarbon solvent to penetrate into the tiny gaps and holes of the object being cleaned, thoroughly cleaning parts with complex shapes. Before batch cleaning of workpieces, the position of slider 15 on linear guide rail 14 is manually or electrically adjusted according to the specific size of the workpiece to control the horizontal spacing and coverage of ultrasonic transducers 13, and the position is locked by fasteners 16; then the height of bracket 12 is adjusted by electric telescopic rod 4 so that ultrasonic transducers 13 maintain the optimal distance from the cleaning liquid surface or workpiece surface. The bracket 12 is installed inside the bin cover 2, and its top is connected to the top of the bin cover via an electric telescopic rod 4. The electric telescopic rod 4 can drive the bracket 12 to rise and fall vertically as a whole, thereby driving all the ultrasonic transducers 13 below to rise and fall synchronously. The bracket 12 and the ultrasonic transducers 13 symmetrically arranged at the bottom are moved vertically downward by the electric telescopic rod 4, so that the ultrasonic transducers 13 are inserted into the cleaning fluid inside the material feeding box 6. After the cleaning of the workpiece is completed, the bracket 12 and the ultrasonic transducers 13 symmetrically arranged at the bottom are moved into the bin cover 2 to facilitate the opening of the bin cover 2.
