Description

Technical Field

[0001] This invention relates to the field of chrome-plated product cleaning equipment, specifically a multi-tank ultrasonic cleaning device for cleaning chrome-plated products. Background Technology

[0002] Although chromium plating itself is corrosion resistant, oil, polishing paste residue, electrolyte salts, or fingerprints may adhere to the surface during the electroplating process. These contaminants can affect the appearance of the plating, its corrosion resistance, and the adhesion of subsequent treatments. Ultrasonic cleaning utilizes the "cavitation effect" to thoroughly clean the surface and tiny pores of chromium-plated parts.

[0003] Existing ultrasonic cleaning tanks include single-tank ultrasonic cleaning tanks and multi-tank ultrasonic cleaning tanks. Single-tank ultrasonic cleaning tanks are the most basic and common type, with a relatively simple structure, mainly composed of a cleaning tank, an ultrasonic generator, and a transducer. They are suitable for scenarios with simple cleaning steps or a single type of workpiece. Multi-tank ultrasonic cleaning tanks have two or more tanks, usually including an ultrasonic cleaning tank and a rinsing tank. Chrome-plated products are first immersed in the ultrasonic cleaning tank and then taken out and placed in the rinsing tank for rinsing. The advantage is that the cleaning efficiency is high and it is suitable for large-scale continuous production.

[0004] Regarding the aforementioned technologies, existing multi-tank ultrasonic cleaning tanks employ a multi-stage counter-current cleaning system to rinse chrome-plated products after ultrasonic cleaning. The chrome-plated products are sequentially immersed in the ultrasonic cleaning tank and the multi-stage rinsing tanks. The water flows in reverse between each rinsing tank, with the final rinsing tank replenished with purified water, overflowing progressively forward. This improves rinsing cleanliness while achieving efficient water resource utilization. However, this system requires the chrome-plated products to be removed from each rinsing tank and transferred to the next tank sequentially, which is cumbersome, prone to secondary contamination, has low automation, and affects production efficiency.

[0005] In summary, existing multi-tank ultrasonic cleaning equipment still suffers from problems such as inconvenient workpiece transfer and high risk of secondary contamination in practical applications. In particular, it is difficult to achieve efficient and stable cleaning results in continuous production. Therefore, there is an urgent need for an improved solution that is compact, highly automated, and can effectively guarantee cleaning quality. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide a multi-tank ultrasonic cleaning device for cleaning chrome-plated products, so as to solve the technical problem of inconvenient workpiece transfer in the practical application of existing multi-tank ultrasonic cleaning devices.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-tank ultrasonic cleaning device for cleaning chrome-plated products, comprising a tank body, the tank body including an ultrasonic cleaning tank and five rinsing tanks arranged in stages, and a frame, the frame being slidably connected to a lifting conveyor frame in the vertical direction, the lifting conveyor frame being equipped with a circulating hanging bracket, the spacing of the hanging bracket being the same as the spacing of the ultrasonic cleaning tank and the rinsing tank, and a movable box, the movable box being slidably connected to the hanging bracket, and the bottom end being rotatably connected to a mounting box for hanging a hanging basket, the connection between the mounting box and the movable box being provided with a damping component.

[0008] By adopting the above technical solution, the hanging baskets are hung on the cyclically moving brackets on the conveyor frame. When the lifting conveyor frame completes one lifting, the brackets simultaneously move one hanging basket position forward, allowing the hanging baskets to be immersed one by one into the corresponding multi-stage cleaning pools of the pool body. This automatically realizes the transfer of chrome-plated products between multi-stage cleaning pools, and can also effectively reduce the risk of secondary pollution caused by human interference.

[0009] The invention is further configured such that multiple vertical guide columns are connected between the two sides of the pool body and the frame, and guide blocks that cooperate with the guide columns are fixedly connected to both sides of the lifting conveyor frame. A rotating shaft is provided at the top of the frame along the length direction, and multiple sets of winding reels are coaxially arranged on the rotating shaft. The winding reels are used to wind up the slings, and one end of the slings is fixedly connected to the connecting plate on the side of the lifting conveyor frame.

[0010] Preferably, the guide column and guide block work together to make the lifting conveyor move smoothly up and down.

[0011] The present invention is further configured such that each sling of the frame is provided with a fixed pulley, the slings that pass around the fixed pulleys are in a vertical state and connected to the connecting plate, and the multiple winding reels can simultaneously wind up and unwind the slings.

[0012] Preferably, the sling applies force to the lifting conveyor frame in a vertical direction.

[0013] The present invention is further configured such that an aeration pipe and a water supply pipe are provided in both the ultrasonic cleaning tank and the last rinsing tank, a first return water pipe is connected to the bottom of the ultrasonic cleaning tank, a second return water pipe is connected to the first rinsing tank, and an overflow channel is provided between the multiple rinsing tanks.

[0014] Preferably, the chrome-plated product is first immersed in an ultrasonic cleaning tank for ultrasonic cleaning, and then rinsed step by step.

[0015] The invention is further configured such that a top cover is fixedly connected to the top of the mobile box, and a spring telescopic column is provided on the top cover facing the hanging bracket. A first friction plate is adhered to the inner wall of the top of the mobile box. When no hanging basket is hung below the mobile box, the first friction plate does not contact the hanging bracket, and vice versa.

[0016] Preferably, the mobile box can be smoothly adjusted in position when the hanging basket is not attached.

[0017] The invention is further configured such that: a mounting shaft is fixedly connected to the bottom end of the movable box; a rotating block is rotatably connected to the mounting shaft; a plurality of insertion holes are arranged in a ring at intervals on the top end of the rotating block; an insertion post is slidably connected to the bottom end of the movable box toward the rotating block; the insertion post is fixedly connected to a fixing plate; when the head of the insertion post is inserted into the insertion hole, the fixing plate contacts the rotating block; an elastic band sleeved on the mounting shaft is fixedly connected to the edge of the fixing plate; and a hanging box for hanging a hanging basket is fixedly connected to the bottom end of the rotating block.

[0018] Preferably, when the basket accelerates and decelerates, the rotating block will rotate slightly. During the rotation of the rotating block, the frictional resistance between the elastic band and the mounting shaft will reduce the shaking of the basket, so as to ensure the smooth movement of the basket.

[0019] The invention is further configured such that a second friction plate is provided between the inner side of the elastic band and the mounting shaft, and the fixing plate does not contact the movable box.

[0020] Preferably, the second friction pad can further increase the frictional resistance between the elastic band and the mounting shaft, while replacing the wear of the elastic band, thereby extending the service life of the elastic band.

[0021] The present invention is further configured such that the cross-section of the part of the mounting box used to mount the hanging basket is trapezoidal, the hook at the top of the hanging basket is adapted to the position of the trapezoidal structure on the mounting box, and the direction of picking up and placing the hanging basket is orthogonal to the direction of conveying the hanging basket.

[0022] Preferably, the direction in which the hook of the hanging basket is put on and taken off is not the same as the direction in which the hanging box shakes, so as to facilitate the taking on and taking off of the hanging basket and also to avoid relative shaking between the hanging box and the hanging basket.

[0023] The present invention is further configured such that an infrared transmitter and an infrared receiver are respectively provided on both sides of the lifting conveyor frame at the end away from the ultrasonic cleaning tank, the infrared transmitter and the infrared receiver are at the same height and both correspond to the height of the hanging basket.

[0024] Preferably, the lifting conveyor can be activated to move the various hanging racks only after the chrome-plated products to be cleaned have been removed.

[0025] The present invention is further configured such that when the hanging basket mounted on the hanging frame is immersed in the pool, there is at least one hanging frame at each end of the pool, and anti-collision frames are fixedly connected to the sides of both ends of the frame.

[0026] Preferably, the hanging racks located at both ends of the pool are used for picking up and putting down the hanging baskets, while the anti-collision racks can effectively prevent the lifting conveyor from bumping into the staff during the lifting process.

[0027] In summary, the present invention has the following main beneficial effects:

[0028] 1. This invention provides a lifting conveyor frame above the multi-stage cleaning tank. The frame uses a hanging rack that moves cyclically to carry the baskets. When the lifting conveyor frame completes one lifting cycle, the hanging rack simultaneously moves one basket forward, allowing the baskets to be immersed one by one into the corresponding multi-stage cleaning tanks. This automatically realizes the transfer of chrome-plated products between the multi-stage cleaning tanks and effectively reduces the risk of secondary pollution caused by human interference.

[0029] 2. This invention sets up an ultrasonic cleaning tank at the beginning of the pool body and sets up five rinsing tanks in sequence. Aeration components are set up in both the ultrasonic cleaning tank and the last rinsing tank. The microbubbles generated by the aeration components enhance the cleaning effect and also facilitate the reverse overflow of water in the rinsing tank. This achieves efficient replacement and cleaning of residual chemicals on the surface of chrome-plated products in the hanging basket, further improving the cleaning quality.

[0030] 3. This invention, by sliding a movable box on the rack, can adaptively adjust the spacing between the hanging baskets according to the size of the chrome-plated products hanging on them, preventing the chrome-plated products from colliding with each other. At the same time, the top cover connected to the top of the movable box is also equipped with a spring telescopic column that contacts the rack. When no hanging basket is hanging below the movable box, it can move smoothly on the rack. When a hanging basket is hanging below the movable box, the weight of the hanging basket will cause the friction plate to contact the rack, thereby preventing the movable box from accidentally sliding on the rack and improving the stability of the hanging basket during transportation.

[0031] 4. By setting a damping pivot structure under the moving box, the present invention reduces the shaking of the hanging basket during acceleration and deceleration, and prevents the hanging basket from hitting the pool or the chrome-plated products on the hanging basket from falling off, thus effectively improving the safety and stability of the transfer process.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The embodiments of the present invention will now be described.

[0049] First embodiment:

[0050] A multi-tank ultrasonic cleaning device for cleaning chrome-plated products, please refer to [link / reference]. Figures 1-13 The system includes a tank body 1, which includes an ultrasonic cleaning tank 101 and five rinsing tanks 102 arranged in stages. The ultrasonic cleaning tank 101 is equipped with an ultrasonic generating component 103. The single-tank ultrasonic cleaning tank is a mature existing technology, and the specific ultrasonic generation principle will not be described in detail here. The ultrasonic cleaning tank 101 and the rinsing tanks 102 are not connected to each other, but the five rinsing tanks 102 are connected to each other. Specifically, an overflow port is provided at the top between two adjacent rinsing tanks 102, and a baffle plate is arranged parallel to the overflow port in the direction of the ultrasonic cleaning tank 101. The baffle plate and the bottom of the rinsing tank 102 have a channel for water to flow through.

[0051] Specifically, both the ultrasonic cleaning tank 101 and the final rinsing tank 102 are equipped with aeration pipes 104 and water supply pipes 105. The microbubbles generated by the aeration components enhance the cleaning effect. At the same time, the aeration components in the final rinsing tank 102 can also fully mix the water in the rinsing tank 102, preventing contaminated water from settling in the final rinsing tank 102 and being unable to flow into the adjacent rinsing tank 102. The bottom of the ultrasonic cleaning tank 101 is connected to a first return water pipe 106, and the first rinsing tank 102 is connected to a second return water pipe 107. When the water in the ultrasonic cleaning tank 101 needs to be replaced, the wastewater can be discharged through the first return water pipe 106, and then water can be replenished into the ultrasonic cleaning tank 101 through the water supply pipe 105.

[0052] Furthermore, overflow channels are provided between the multi-stage rinsing tanks 102. The chrome-plated product is first immersed in the ultrasonic cleaning tank 101 for ultrasonic cleaning, and then rinsed in stages. In the multi-stage rinsing tanks 102, the rinsing tank 102 closest to the ultrasonic cleaning tank 101 has the highest degree of contamination, and the degree of contamination gradually decreases. The water in the last rinsing tank 102 has the highest degree of cleanliness. In the multi-stage rinsing tanks 102, the specific direction of water flow is that the water in the last rinsing tank 102 flows into the penultimate rinsing tank 102 through the overflow port, and then flows downward, bypassing the bottom of the baffle plate and entering the penultimate rinsing tank 102. This flow continues until the first rinsing tank 102, and finally flows out through the second return water pipe 107, and is transferred to the water purification equipment for filtration and regeneration. This can significantly reduce water consumption, while also achieving a good cleaning effect.

[0053] It also includes a frame 2, which is slidably connected to a lifting conveyor frame 3 in the vertical direction. A cyclically moving hanger 301 is installed on the lifting conveyor frame 3. Specifically, the lifting conveyor frame 3 is equipped with a cyclically moving conveyor chain, and the two ends of the hanger 301 are respectively connected to two chains. The hanger 301 will also cyclically move synchronously during the cyclical movement of the chains.

[0054] Furthermore, the spacing of the hangers 301 is the same as the spacing of the ultrasonic cleaning tank 101 and the rinsing tank 102. When the hanging basket 4 mounted on the hanger 301 is immersed in the tank body 1, there is at least one hanger 301 at each end of the tank body 1. This ensures that after the hangers 301 move the same distance, each hanging basket 4 can be smoothly immersed in the corresponding ultrasonic cleaning tank 101 or rinsing tank 102. The hangers 301 located at both ends of the tank body 1 make it convenient for staff to pick up and put down the hanging basket 4.

[0055] Specifically, when the lifting conveyor 3 descends and the hanging basket 4 located above the ultrasonic cleaning tank 101 or rinsing tank 102 is immersed in the water, the staff can then pick up and put down the hanging basket 4 at both ends of the tank 1.

[0056] It also includes a movable box 5, which is slidably connected to the hanger 301, and has a hanging box 8 for hanging the hanging basket 4 rotatably connected to its bottom end. A damping component is provided at the connection between the hanging box 8 and the movable box 5 to reduce the shaking of the hanging basket 4 during its movement, thereby improving the stability of the hanging basket 4.

[0057] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 , Figures 6-7The pool body 1 is connected to the frame 2 by multiple vertical guide columns 201 on both sides. The lifting conveyor frame 3 is fixedly connected to both sides by guide blocks 302 that cooperate with the guide columns 201. The top of the frame 2 is provided with a rotating shaft 10 along the length direction. Multiple sets of winding reels 11 are coaxially provided on the rotating shaft 10. The winding reels 11 are used to wind up the sling 12. Specifically, the frame 2 is equipped with a drive motor and a gearbox for driving the rotating shaft 10 to rotate. When the drive motor works in both directions, the rotating shaft 10 can rotate in both directions. By controlling the rotation of the rotating shaft 10, the winding reels 11 can be controlled to wind up and unwind the sling 12.

[0058] Specifically, one end of the sling 12 is fixedly connected to the connecting plate 303 on the side of the lifting conveyor frame 3. The guide column 201 and the guide block 302 work together to make the lifting conveyor frame 3 move up and down smoothly. In this embodiment, a total of three sets of take-up reels 11 are provided. Each set of take-up reels 11 has two rolls of sling 12 wound up. The ends of these two rolls of sling 12 are respectively connected to the connecting plates 303 on both sides of the lifting conveyor frame 3, while the other ends are located at the top and bottom of the take-up reel 11, thereby realizing that the take-up reel 11 rotates to simultaneously wind up or release the sling 12.

[0059] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 , Figure 5 The sides of both ends of the frame 2 are fixedly connected with anti-collision frames 202. The length of the anti-collision frames 202 is greater than the length of the lifting conveyor frame 3 that extends beyond the pool body 1. The hanging frames 301 located outside both ends of the pool body 1 are used to pick up and put down the hanging basket 4. The anti-collision frames 202 can effectively prevent the lifting conveyor frame 3 from bumping into the staff during the lifting process.

[0060] For details regarding the above embodiments, please refer to [link / reference]. Figures 7-13 The bottom of the movable box 5 is fixedly connected to the mounting shaft 502, and the mounting shaft 502 is rotatably connected to the rotating block 7. The top of the rotating block 7 is provided with multiple insertion holes 701 in a ring. The bottom of the movable box 5 is slidably connected to the insertion post 901 in the direction of the rotating block 7. The insertion post 901 is fixedly connected to the fixing plate 9. When the head of the insertion post 901 is inserted into the insertion hole 701, the fixing plate 9 contacts the rotating block 7.

[0061] Furthermore, the edge of the fixing plate 9 is fixedly connected to an elastic band 902 that is sleeved on the mounting shaft 502, and the bottom end of the rotating block 7 is fixedly connected to a mounting box 8 for hanging the hanging basket 4. When the hanging basket 4 accelerates and decelerates, the rotating block 7 will rotate slightly due to the inertia of the hanging basket 4 itself.

[0062] Specifically, when the rotating block 7 rotates, the head of the insertion post 901 will exit from the insertion hole 701, and at the same time, the elastic band 902 will undergo elastic deformation. As the rotating block 7 continues to rotate, when the insertion post 901 is aligned with the next insertion hole 701, the insertion post 901 will be inserted into the next insertion hole 701 due to the elastic force of the elastic band 902. During the rotation of the rotating block 7, the frictional resistance between the elastic band 902 and the mounting shaft 502 reduces the shaking of the hanging basket 4 to ensure the smooth movement of the hanging basket 4. When the hanging basket 4 is stationary, the rotating block 7 will rotate back to the vertically downward state due to the gravity of the hanging basket itself.

[0063] Second embodiment:

[0064] A multi-tank ultrasonic cleaning device for cleaning chrome-plated products, please refer to [link / reference]. Figures 1-13 Based on the first embodiment, the difference from the first embodiment is that the top of the movable box 5 is fixedly connected to the top cover 6, and the top cover 6 is provided with a spring telescopic column 601 facing the bracket 301. Specifically, one end of the spring telescopic column 601 is in contact with the bracket 301, while the other end is provided with a compression spring in a compressed state between it and the top cover 6.

[0065] Furthermore, the inner wall of the top of the movable box 5 is bonded with a first friction plate 501. In this embodiment, the hanging bracket 301 is provided with a chamfer in the direction of the top cover 6, and the first friction plate 501 is parallel to the chamfer. When the hanging basket 4 is not hung below the movable box 5, the first friction plate 501 does not contact the hanging bracket 301. On the contrary, the weight of the hanging basket 4 exerts a downward force on the movable box 5, further compressing the compression spring in the top cover 6, thereby making the first friction plate 501 contact the hanging bracket 301, so that the movable box 5 can be smoothly adjusted in position when the hanging basket 4 is not hung, and is not easy to slide after the hanging basket 4 is hung.

[0066] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 , Figures 6-7 Each sling 12 in the frame 2 is equipped with a fixed pulley 203. The sling 12 that passes over the fixed pulley 203 is in a vertical state and connected to the connecting plate 303. Multiple reel 11 can simultaneously reel in and out the sling 12, so that the sling 12 applies force to the lifting conveyor 3 in the vertical direction, so as to prevent the sling 12 from tilting or deviating during the reeling and unwinding process, and ensure that the lifting conveyor 3 can be lifted and lowered smoothly.

[0067] For details regarding the above embodiments, please refer to [link / reference]. Figures 10-13A second friction plate 903 is provided between the inner side of the elastic band 902 and the mounting shaft 502. The fixing plate 9 does not contact the moving box 5 to avoid the fixing plate 9 interfering with the sliding of the insertion post 901. The second friction plate 903 can further increase the frictional resistance between the elastic band 902 and the mounting shaft 502, and at the same time replace the wear of the elastic band 902, thereby extending the service life of the elastic band 902.

[0068] For details regarding the above embodiments, please refer to [link / reference]. Figures 8-10 The section of the mounting box 8 used to hang the hanging basket 4 has a trapezoidal structure. The hook at the top of the hanging basket 4 is matched with the position of the trapezoidal structure on the mounting box 8. The direction of picking up and putting down the hanging basket 4 is orthogonal to the direction of conveying the hanging basket 4. The direction of picking up and putting down the hook of the hanging basket 4 is not in the same direction as the swing of the mounting box 8. This makes it easy to pick up and put down the hanging basket 4, and also avoids relative swaying between the mounting box 8 and the hanging basket 4.

[0069] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 , Figure 7 Infrared transmitters 304 and infrared receivers 305 are respectively installed on both sides of the lifting conveyor 3 at the end away from the ultrasonic cleaning tank 101. The infrared transmitters 304 and infrared receivers 305 are at the same height and correspond to the height of the hanging baskets 4. The lifting conveyor 3 can only be started to move each hanging rack 301 after the cleaned chrome-plated product is removed. This prevents the hanging baskets 4 from flipping when the lifting conveyor 3 starts conveying before the hanging baskets 4 on the hanging racks 301 are removed, thus ensuring the safe operation of the chrome-plated product cleaning work.

[0070] In the specific cleaning of chrome-plated products, the present invention:

[0071] When the lifting conveyor 3 is in the lowering state, at the end of the pool body 1 near the ultrasonic cleaning pool 101, adjust the position of the moving box 5 on the hanger 301 so that the distance between adjacent moving boxes 5 is sufficient to prevent the chrome-plated products on adjacent hanging baskets 4 from contacting each other. Hang the hanging basket 4 with the chrome-plated products on the hanging box 8. At the other end of the pool body 1, directly remove the cleaning hanging basket 4.

[0072] The lifting conveyor 3 rises so that the bottom of the hanging basket 4 is higher than the top of the pool body 1. Then, the lifting conveyor 3 begins to circulate and transport the hanging rack 301, causing the hanging rack 301 to move as a whole by one hanging basket 4 position. The hanging basket 4, which was not originally above the pool body 1, moves to above the ultrasonic cleaning pool 101, while the hanging basket 4, which was originally above the ultrasonic cleaning pool 101, moves to above the first-stage rinsing pool 102, and so on. Then, the height of the lifting conveyor 3 decreases. This cycle can realize the automated and efficient transfer of the hanging basket 4 between the ultrasonic cleaning pool 101 and the multi-stage rinsing pool 102, thereby reducing the risk of secondary contamination while performing ultrasonic cleaning of chrome-plated products.

[0073] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
