Description

Technical Field

[0001] The present invention relates to the field of cleaning chromium-plated products, and specifically to a cleaning device and a cleaning method for chromium-plated products. Background Art

[0002] Electroplating solutions usually contain acidic or alkaline components. If not thoroughly removed, the residual liquid will continuously corrode the coating and the base metal, resulting in problems such as yellowing of the coating and rust spots. Cleaning is not only related to the appearance and performance of the coating, but also closely related to production costs and environmental compliance.

[0003] In the prior art, ultrasonic cleaning tanks are generally used for cleaning chromium-plated products. After loading the chromium-plated products into the cleaning basket, they are placed in the cleaning tank for ultrasonic cleaning. After cleaning, they are taken out and another basket of chromium-plated products to be cleaned is replaced. In the prior art, multiple cleaning tanks are also arranged side by side, and a linear walking mechanism is used in cooperation with a grasping component to sequentially place the cleaning baskets containing chromium-plated products into the multiple side-by-side cleaning tanks for multi-stage gradient cleaning according to the characteristics of the chromium-plated products, further improving the cleaning quality of the chromium-plated products.

[0004] In view of the above related technologies, the existing chromium-plated product cleaning equipment needs to use a linear walking mechanism in cooperation with a lifting grasping component to realize the transfer of each cleaning basket in different cleaning tanks. The grasping component can only grasp one cleaning basket at a time. When it is desired to move the cleaning baskets in multiple cleaning tanks one position backward to the subsequent cleaning tank, it is necessary to move the cleaning baskets in multiple cleaning tanks one by one, which easily affects the cleaning efficiency of the chromium-plated products. In summary, the cleaning efficiency of the existing chromium-plated product cleaning equipment needs to be improved. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a cleaning device and a cleaning method for chromium-plated products to solve the technical problem that the cleaning efficiency of the existing chromium-plated product cleaning equipment needs to be improved.

[0006] To achieve the above object, the present invention provides the following technical solution: A cleaning device for chromium-plated products, including a main body. A plurality of cleaning boxes for cleaning chromium-plated products are arranged at intervals inside the main body. Loading platforms are installed on both sides inside the main body close to the cleaning boxes. A transfer box is further included. The transfer box is arranged between adjacent cleaning boxes and is also provided between the loading platform and the cleaning box. A receiving basket for containing chromium-plated products can be placed inside the cleaning box. A telescopic rod is connected inside the transfer box. The top end of the telescopic rod is connected to a transfer rack for clamping the top end of one side of the receiving basket. The bottom end of the telescopic rod is provided with a driving structure for driving the telescopic rod to rotate along the axis of the telescopic rod. When the telescopic rod is fully extended, the bottom end of the receiving basket is higher than the top end of the cleaning box.

[0007] By adopting the above technical solution, after the transfer mechanism hangs the accommodation basket, it is lifted and rotated above the cleaning tank of the subsequent process and then lowered, completing the convenient transfer of the accommodation basket between adjacent cleaning tanks. Multiple cleaning tanks in the cleaning equipment can simultaneously transfer the accommodation basket, greatly improving the cleaning efficiency of chromium-plated products.

[0008] The present invention is further configured such that a bearing plate is slidably provided in the cleaning tank in the vertical direction. The bottom end of the bearing plate is connected to a floating box, and a locking structure for positioning the accommodation basket is provided on the top surface.

[0009] Preferably, by adjusting the buoyancy of the floating box, the reciprocating adjustment of the height of the accommodation basket is realized, further improving the cleaning quality of chromium-plated products.

[0010] The present invention is further configured such that the floating box is composed of an upper shell and a lower shell spliced oppositely. Through grooves and drainage cavities are arranged at intervals in the length direction in the floating box, and the space in the floating box except for the drainage cavity is a sealed cavity filled with air.

[0011] Preferably, injecting air into the drainage cavity can realize the rising of the accommodation basket.

[0012] The present invention is further configured such that exhaust holes are arranged at intervals in the width direction at the top end of each drainage cavity of the upper shell, and drainage holes are arranged at intervals in the width direction at the bottom end of each drainage cavity of the lower shell. All the drainage cavities are connected through air guide pipes arranged in the floating box. An air inlet pipe penetrating through the outside of the floating box is connected to the drainage cavity in the middle of the floating box. Vertical through holes are arranged at the positions of the bearing plate corresponding to the through grooves.

[0013] Preferably, the air injected into the drainage cavity leaves the drainage cavity through the exhaust holes and generates dense small bubbles. The small bubbles can further improve the removal efficiency of dirt on the surface of chromium-plated products during the rising process.

[0014] The present invention is further configured such that a cylinder is installed in the transfer box. A push rod extending upward out of the cylinder is coaxially connected in the cylinder. The bottom end of the push rod is connected to a piston, and the top end is fixedly connected to a pressing plate. An elastic reset mechanism is arranged between the pressing plate and the cylinder. The bottom end of the cylinder is connected to the air inlet pipe through an air delivery pipe located in the accommodation basket. The transfer rack can press down the pressing plate during the process of rotating above the pressing plate and then descending.

[0015] Preferably, the transfer rack presses down the pressing plate through the contraction of the telescopic rod, exhausting the air in the cylinder, and making the air be injected into the drainage cavity through the air delivery pipe.

[0016] The present invention is further configured such that the middle parts of the four sides of the top surface of the supporting plate are rotatably connected with locking blocks of an L-shaped structure, and the supporting plate is provided with an insert block at the end of the locking block's rotating shaft away from the containing basket, and the bottom end of the insert block is fixedly connected with a floating block. When the supporting plate sinks below the liquid surface, the insert block is tightly attached to the side of the locking block away from the containing basket. At this time, the locking block is restricted by the containing basket and the insert block and cannot rotate. After the supporting plate leaves the water surface, the insert block cannot restrict the rotation of the locking block.

[0017] Preferably, the receiving basket is locked while being lowered, and when the receiving basket is lifted, the lock between the receiving basket and the carrying plate is automatically released when the carrying plate leaves the liquid surface.

[0018] The present invention is further configured such that the bottom end of the transfer box is rotatably connected to a rotating drum, and a driving structure for driving the rotating drum to rotate is arranged inside; the rotating drum is rotatably connected to a telescopic rod in a radial direction, and a driving structure for driving the telescopic rod to rotate is also arranged inside.

[0019] Preferably, the inclination angle of the telescopic rod can be adjusted by rotating the rotating drum.

[0020] The present invention is further configured such that two parallel hanging rods are arranged on the same plane on both sides of the top of the accommodating basket, and support rods parallel to the hanging rods are fixedly connected below the hanging rods, the top of the transfer rack is fixedly connected with a first protrusion for clamping one of the hanging rods, and the bottom end is fixedly connected with an extension plate extending downward, and the bottom end of the extension plate is fixedly connected with a second protrusion for contacting the support rod.

[0021] Preferably, the receiving basket is lifted from one side of the receiving basket by means of multi-point support, so as to avoid the receiving basket from tilting when being lifted.

[0022] The present invention is further configured such that when the telescopic rod is in a vertical state, its own axis is located in the middle of two adjacent receiving baskets, and both sides of all the receiving baskets are symmetrical to each other. After the rotating drum rotates, the transfer rack can leave or extend into the cleaning box without interfering with the receiving baskets.

[0023] Preferably, the containing basket is prevented from restricting the movement of the transport rack.

[0024] A method for cleaning chrome-plated products, the process comprising the following steps: After the cleaning box has finished cleaning the chrome-plated products in the receiving basket, the transfer rack cooperates with the top of one side of the receiving basket, and the telescopic rod in a vertical state extends to make the receiving basket leave the water surface until the bottom end of the receiving basket rises to a height exceeding the top of the cleaning box; After the telescopic rod rotates 180 degrees, the accommodating basket is positioned above the cleaning tank or the loading table in the subsequent process, and then the telescopic rod contracts to lower the accommodating basket. The rotating cylinder rotates to adjust the inclination angle of the telescopic rod, enabling the transfer rack to disengage from the current accommodating basket. The telescopic rod rotates 180 degrees in the reverse direction and contracts and resets to the state where it contacts the top end of the side of the accommodating basket on the cleaning tank or the loading table in the previous process.

[0025] In summary, the present invention mainly has the following beneficial effects: 1. By arranging a transfer mechanism between adjacent cleaning tanks, the present invention uses the transfer mechanism to lift and rotate the accommodating basket after hanging it and then lower it above the cleaning tank in the subsequent process, completing the convenient transfer of the accommodating basket between adjacent cleaning tanks. Multiple cleaning tanks in the cleaning equipment can transfer the accommodating baskets simultaneously, greatly improving the cleaning efficiency of chromium-plated products.

[0026] 2. By slidably arranging a bearing plate vertically in the cleaning tank and providing a locking structure on the bearing plate for locking and cooperating with the accommodating basket, when the accommodating basket is placed on the bearing plate and lowered, the buoyancy of the liquid in the cleaning tank is used to conveniently lock the accommodating basket. When the accommodating basket is lifted upward until the bearing plate is out of the liquid surface, the unlocking of the locking structure can be conveniently completed, effectively improving the stability of the accommodating basket during the cleaning process in the cleaning tank, avoiding the chromium-plated products in the accommodating basket from colliding with each other, and also facilitating the transfer mechanism to conveniently transfer each accommodating basket.

[0027] 3. By fixedly connecting a floating box structure to the bottom surface of the bearing plate and controlling the reciprocating floating and sinking of the floating box by injecting air into the drainage cavity in the floating box, the chromium-plated products in the bearing frame can be fully contacted with the cleaning liquid. At the same time, the dense bubbles generated by the air discharged from the drainage cavity can further improve the cleaning quality of the chromium-plated products, shorten the cleaning time of the chromium-plated products, and thus improve the cleaning efficiency of the chromium-plated products.

[0028] 4. By sequentially arranging a hanging rod and a supporting rod from high to low on both sides of the accommodating basket for cooperating with the first convex block and the second convex block on the transfer rack respectively, when the telescopic rod extends to lift the accommodating basket out of the water surface, the transfer rack is clamped with the two hanging rods through the first convex block, and the second convex block presses the supporting rod, which can effectively ensure the stability of the accommodating basket during the transfer process and avoid excessive inclination of the accommodating basket due to its own weight and the weight of the chromium-plated products during the transfer process.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0032] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0033] The first embodiment: A cleaning device for chromium-plated products, please refer to Figure 1-17 , including a main machine 1, and a plurality of cleaning tanks 2 for cleaning chromium-plated products are arranged at intervals in the main machine 1. Specifically, in this embodiment, the cleaning tank 2 is an ultrasonic cleaning tank. On both sides of the main machine 1 near the cleaning tank 2, a feeding table 20 is installed. On both sides of the feeding table 20, guide bars 2001 for guiding the accommodating basket 4 are fixedly connected, and a blocking bar 2002 for positioning the accommodating basket 4 is fixedly connected at the rear end. Pushing the accommodating basket 4 from the front end to the rear end of the feeding table 20 can realize the positioning of the accommodating basket 4, facilitating the transfer mechanism in the transfer box 3 to accurately transfer the accommodating basket 4 into the subsequent cleaning tank 2.

[0034] It further includes a transfer box 3 which is arranged between adjacent cleaning boxes 2 and is also arranged between the loading table 20 and the cleaning box 2. A receiving basket 4 for holding chromium-plated products can be placed in the cleaning box 2. Specifically, a plurality of partition plates 16 for separating chromium-plated products are arranged at intervals along the length direction inside the receiving basket 4. A plurality of groups of partition blocks 404 are arranged at intervals along the length direction in the middle of the receiving basket 4. Both ends of the partition plate 16 are fixedly connected with side bars 1601, and the bottom end is fixedly connected with plugs 1602 for inserting between the partition blocks 404. When the plugs 1602 of the partition plate 16 are inserted into the partition blocks 404, combined with the side bars 1601, it can effectively prevent the partition plate 16 from tilting inside the receiving basket 4, playing a role in stabilizing the partition plate 16.

[0035] Furthermore, a telescopic rod 8 is arranged in the space in the middle of the transfer box 3. The top end of the telescopic rod 8 is connected with a transfer rack 9 for clamping the top end of one side of the receiving basket 4. The bottom end of the telescopic rod 8 is installed with a driving structure for driving the telescopic rod 8 to rotate along the axis direction of the telescopic rod 8. When the telescopic rod 8 is fully extended, the bottom end of the receiving basket 4 is higher than the top end of the cleaning box 2.

[0036] In the above embodiment, specifically, please refer to Figure 2-5 , a bearing plate 5 is slidably arranged vertically inside the cleaning box 2. Four vertical guide rods 201 are fixedly connected inside the cleaning box 2. The bearing plate 5 is slidably connected to the guide rods 201. The bottom end of the bearing plate 5 is connected with a floating box 6, and a locking structure for positioning the receiving basket 4 is arranged on the top surface. The locking structure can ensure that there is no relative horizontal sliding between the receiving basket 4 and the bearing plate 5, thereby ensuring the stability of the receiving basket 4. By adjusting the buoyancy of the floating box 6, the height of the receiving basket 4 can be reciprocally adjusted, so that the chromium-plated products in the receiving basket 4 can reciprocally move up and down in the cleaning liquid, further improving the cleaning quality of the chromium-plated products.

[0037] Specifically, the floating box 6 is composed of an upper shell 601 and a lower shell 602 spliced oppositely. Inside the floating box 6, a through groove 607 and a drainage cavity 604 are arranged at intervals along the length direction. The space inside the floating box 6 except for the drainage cavity 604 is a sealed cavity 603 filled with air. At the bottom end of each drainage cavity 604 in the lower shell 602, drainage holes 605 are arranged at intervals along the width direction. All the drainage cavities 604 are connected through an air duct 15 arranged inside the floating box 6. Injecting air into the drainage cavity 604 can realize the rising of the receiving basket 4. Specifically, when chromium-plated products are placed in the receiving basket 4 and placed on the bearing plate 5, the gravity of the receiving basket 4, the bearing plate 5 and the floating box 6 is slightly greater than the buoyancy in the state where the drainage cavity 604 is filled with water. When air is injected into the drainage cavity 604, the whole receiving basket 4 will float. During the floating process, the air in the drainage cavity 604 is discharged through the exhaust holes 606, and the buoyancy decreases and it will sink again. Injecting an appropriate amount of air into the drainage cavity 604 at intervals can realize the reciprocating up and down movement of the whole receiving basket 4.

[0038] Furthermore, drainage holes 605 are arranged at the positions of the lower shell 602 corresponding to the drainage cavities 604. When the pressure in the drainage cavity 604 increases due to the injection of air, the original water in the drainage cavity 604 can be quickly discharged through the drainage holes 605, so that the air can be quickly and evenly conducted into each drainage cavity 604 through the air duct 15. Specifically, the two ends of the air duct 15 are respectively connected to two drainage cavities 604, and air guide holes 1501 for connecting each drainage cavity 604 are arranged at the positions of the drainage cavities 604 passed by the middle section.

[0039] In the above embodiment, specifically, please refer to Figure 9-12 , on both sides of the top end of the receiving basket 4, two parallel hanging rods 401 are arranged on the same plane, and a support rod 402 parallel to the hanging rods 401 is fixedly connected below the hanging rods 401. A first convex block 902 for clamping one of the hanging rods 401 is fixedly connected to the top end of the transfer rack 9, and an extension plate 901 extending downward is fixedly connected to the bottom end. Specifically, the top end of the transfer rack 9 can support the two hanging rods 401 at the same time. A second convex block 903 for contacting the support rod 402 is fixedly connected to the bottom end of the extension plate 901. The receiving basket 4 is lifted from one side by means of multi-point support, avoiding the situation that the receiving basket 4 tilts when it is lifted.

[0040] Furthermore, two positioning blocks 403 are connected between two adjacent hanging rods 401. The distance between the positioning blocks 403 is the same as the length of the first convex block 902 on the transfer rack 9. Chamfered corners are also arranged at the ends of the positioning blocks 403 close to each other. Specifically, the two positioning blocks 403 between two adjacent hanging rods 401 play a guiding role for the transfer rack 9 to ensure that the transfer rack 9 can be aligned with the correct position of the receiving basket 4.

[0041] In the above embodiment, specifically, please refer to Figure 2-5 , a rotating cylinder 7 is rotatably connected to the bottom end inside the transfer box 3, and a driving structure for driving the rotation of the rotating cylinder 7 is arranged inside. Specifically, in this embodiment, a large gear is arranged at the end of the rotating cylinder 7, and a driving motor is arranged inside the transfer box 3. The transmission component connected to the driving motor extends out of the transfer box 3 and is connected to a small gear that meshes with the large gear. By operating the driving motor located inside the transfer box 3, the rotation angle of the rotating cylinder 7 is adjusted, and thus the inclination angle of the telescopic rod 8 is adjusted.

[0042] Furthermore, the rotating cylinder 7 is rotatably connected to the telescopic rod 8 in the radial direction, and a driving structure for driving the rotation of the telescopic rod 8 is also arranged inside. Specifically, the telescopic rod 8 can be a telescopic component such as an electric telescopic rod or a hydraulic telescopic rod. In this embodiment, the telescopic rod 8 is specifically an electric telescopic rod, and the driving structure of the telescopic rod 8 is specifically installed inside the rotating cylinder 7. The driving motor located inside the rotating cylinder 7 directly drives the telescopic rod 8 to rotate around its own axis. When the rotating cylinder 7 rotates, the inclination angle of the telescopic rod 8 can be adjusted.

[0043] In the above embodiment, specifically, please refer to Figure 2-5 , when the telescopic rod 8 is in the vertical state, its own axis is located exactly in the middle between two adjacent receiving baskets 4. Both sides of all the receiving baskets 4 are symmetric with each other, ensuring that the telescopic rod 8 can cooperate with the transfer rack 9 to accurately transfer each receiving basket 4. After the rotating cylinder 7 rotates, the transfer rack 9 can leave or extend into the cleaning tank 2 without interfering with the receiving baskets 4, avoiding the restriction of the movement of the transfer rack 9 by the receiving baskets 4.

[0044] Please refer in detail to Figure 1 , the cleaning tank 2 at the front end where the main machine 1 first cleans the chromium-plated products in the receiving basket 4 is the cleaning tank 2 at the front end. Similarly, the cleaning tank 2 at the end where the chromium-plated products are finally cleaned is the cleaning tank 2 at the end. A drain pipe 22 is connected to the cleaning tank 2 at the front end of the main machine 1, and a liquid inlet pipe 21 is connected to the cleaning tank 2 at the end. A liquid transfer pipe 23 is connected between adjacent cleaning tanks 2. A water pump is arranged in the middle of the liquid transfer pipe 23. The water in the cleaning tank 2 at the end of the main machine 1 is the cleaning water in the last stage of the cleaning process, and the water in the cleaning tank 2 at the front end is the cleaning water that first cleans the chromium-plated products in the cleaning process. When the quality of the cleaning water in the cleaning tank 2 at the front end does not meet the standard, the water in this cleaning tank 2 is discharged through the drain pipe 22. The cleaning water in each cleaning tank 2 is transferred in a gradient manner by using the liquid transfer pipe 23. Finally, clean cleaning water is injected into the cleaning tank 2 at the end through the liquid inlet pipe 21, achieving the gradient utilization of wastewater, improving the cleaning efficiency of chromium-plated products, and saving the cleaning cost of chromium-plated products.

[0045] The second embodiment: A cleaning device for chromium-plated products, please refer to Figure 1-17, on the basis of the first embodiment, which is different from the first embodiment in that exhaust holes 606 are arranged at intervals in the width direction at the top end of each drainage cavity 604 of the upper housing 601. An air inlet pipe 14 that penetrates to the outside of the floating box 6 is connected in the drainage cavity 604 in the middle of the floating box 6. Vertical through holes are arranged at the positions of the carrier plate 5 corresponding to the through slots 607. The air injected into the drainage cavity 604 leaves the drainage cavity 604 through the exhaust holes 606 to generate dense small bubbles. The small bubbles can further improve the removal efficiency of dirt on the surface of the chrome-plated product during the rising process.

[0046] Further, an air cylinder 10 is installed in the transfer box 3. A pressure rod 11 that extends upward out of the air cylinder 10 is coaxially connected in the air cylinder 10. A piston is connected to the bottom end of the pressure rod 11, and a pressing plate 12 is fixedly connected to the top end. An elastic reset mechanism is arranged between the pressing plate 12 and the air cylinder 10. Specifically, in this embodiment, the elastic reset mechanism is a spring. When the pressing plate 12 is not subjected to a downward pressure, it will be reset by the elastic force of the spring. During the reset process of the pressure rod 11, the piston rises to suck the outside air into the air cylinder 10, and its specific principle is similar to that of a pump.

[0047] Furthermore, the bottom end of the air cylinder 10 is connected to the air inlet pipe 14 through an air delivery pipe 13 located in the receiving basket 4. Specifically, the air delivery pipe 13 is a flexible pipe, which makes a U-shaped bend in the cleaning box 2 to ensure stable air delivery during the up and down floating of the floating box 6. When the transfer rack 9 rotates above the pressing plate 12 and then descends, it can press down the pressing plate 12. The transfer rack 9 presses down the pressing plate 12 through the contraction of the telescopic rod 8 to discharge the air in the air cylinder 10, so that the air is injected into the drainage cavity 604 through the air delivery pipe 13.

[0048] The third embodiment: A cleaning device for chrome-plated products, please refer to Figure 1-17 , on the basis of the second embodiment, which is different from the second embodiment in that L-shaped locking blocks 17 are rotatably connected to the middle parts of the four sides of the top surface of the carrier plate 5. The carrier plate 5 is provided with insertion blocks 19 at the ends of the rotating shafts of the locking blocks 17 away from the receiving basket 4. A floating block 18 is fixedly connected to the bottom end of the insertion block 19. When the carrier plate 5 sinks below the liquid level, the insertion block 19 closely adheres to the side of the locking block 17 away from the receiving basket 4. At this time, the locking block 17 is restricted by the receiving basket 4 and the insertion block 19 and cannot rotate. After the carrier plate 5 leaves the water surface, the insertion block 19 cannot restrict the rotation of the locking block 17. The locking of the receiving basket 4 is realized while putting down the receiving basket 4, and when the receiving basket 4 is lifted, the locking between the receiving basket 4 and the carrier plate 5 can be automatically released when the carrier plate 5 leaves the liquid level.

[0049] Specifically, the supporting plate 5 is provided with a first receiving groove 501 for the locking block 17 to rotate and a second receiving groove 502 for the floating block 18 to move up and down. The bottom end of the second receiving groove 502 is provided with a water hole 503. When the supporting plate 5 leaves the water surface, the water in the second receiving groove 502 flows out through the water hole 503, so that the floating block 18 and the insert block 19 can slide down to the position where the locking block 17 cannot be restricted from rotating due to their own gravity, thereby conveniently realizing the unlocking of the receiving basket 4.

[0050] A method for cleaning chrome-plated products, the process comprising the following steps: After the cleaning box 2 has finished cleaning the chrome-plated products in the receiving basket 4, the transfer frame 9 cooperates with the top of one side of the receiving basket 4, and the telescopic rod 8 in a vertical state extends to make the receiving basket 4 leave the water surface until the bottom end of the receiving basket 4 rises to a height exceeding the top of the cleaning box 2; After the telescopic rod 8 rotates 180 degrees, the receiving basket 4 is placed above the cleaning box 2 or the loading platform 20 of the next process, and then the telescopic rod 8 is retracted to put the receiving basket 4 down; The rotating drum 7 rotates to adjust the inclination angle of the telescopic rod 8 so that the transfer frame 9 can be out of contact with the current receiving basket 4. The telescopic rod 8 rotates 180 degrees in the opposite direction and shrinks and resets to the state where the cleaning box 2 or the loading platform 20 of the previous process contacts the top of one side of the receiving basket 4.

[0051] When the present invention specifically cleans chrome-plated products: The hopper 9 is moved upwards to the top of the loading platform 20, and the hopper 9 is moved downwards to the bottom of the loading platform 20, and the hopper 9 is moved downwards to the top of the loading platform 20, and the hopper 9 is moved upwards to the bottom of the loading platform 20, and the hopper 9 is moved downwards to the top of the loading platform 20, and the hopper 9 is moved downwards to the bottom ... bottom of the loading platform 20, and the hopper 9 is moved downwards to the bottom of the loading platform 20, and the hopper 9 is moved When the telescopic rod 8 is retracted to make the height of the receiving basket 4 drop, the bottom end of the receiving basket 4 contacts the supporting plate 5 floating on the water surface, and the edge of the receiving basket 4 presses down the locking block 17, causing the locking block 17 to rotate, and then the receiving basket 4 continues to move downward to press the supporting plate 5 below the water surface, and the floating block 18 floats up to make the plug block 19 rise, and the plug block 19 pushes the locking block 17 away from the side of the receiving basket 4 to make the locking block 17 further rotate, until the locking block 17 presses the receiving basket 4 while leaning against the plug block 19, and the plug block 19 and the receiving basket 4 are used to limit the rotation of the locking block 17 at the same time, thereby completing the horizontal limit of the receiving basket 4, and preventing the receiving basket 4 from moving horizontally during the cleaning process. Similarly, when the receiving basket 4 is lifted and the supporting plate 5 is out of the water, the floating block 18 falls down due to its own gravity, causing the plug block 19 to be out of contact with the part above the rotating shaft of the locking block 17. At this time, the receiving basket 4 continues to move upward to push the locking block 17 to rotate, so as to conveniently realize the locking and unlocking of the receiving basket 4; During the cleaning process of the chrome-plated products in the receiving basket 4, the telescopic rod 8 in the transfer box 3 rotates so that the transfer frame 9 is directly above the pressure plate 12. The telescopic rod 8 reciprocates and retracts a fixed number of times at a fixed interval, and the transfer frame 9 presses down the pressure plate 12 to squeeze out the air in the air cylinder 10, and transmits it to the drainage chamber 604 of the float box 6 through the air supply pipe 13. After discharging part of the water in the drainage chamber 604, the overall buoyancy formed by the float box 6, the supporting plate 5 and the receiving basket 4 is greater than the gravity and rises. The water in the cleaning box 2 will continuously enter the drainage chamber 604 from the exhaust hole 606, causing the receiving basket 4 to sink after rising. In this way, the reciprocating up and down movement of the receiving basket 4 is realized, thereby improving the cleaning quality of the chrome-plated products. At the same time, the bubbles discharged from the exhaust hole 606 will also pass through the chrome-plated products in the receiving basket 4 during the rising process, thereby further improving the cleaning quality of the chrome-plated products and improving the cleaning efficiency of the chrome-plated products. After the chrome-plated products are cleaned, all the receiving baskets 4 are synchronously transported again, and the cleaning work of the chrome-plated products is efficiently achieved in this reciprocating manner.
