Description

A steel plate phosphating cleaning device Technical Field

[0001] This invention relates to the technical field of steel plate cleaning devices, and particularly to a steel plate phosphate cleaning device. Background Technology

[0002] Steel plates are the raw materials used to manufacture the body, top cover, and bottom cover of steel drums. The traditional steel plate processing method involves cutting, welding, stamping, and then phosphate cleaning. This means that phosphate cleaning can only clean the body of the drum and cannot clean the inside of the drum at the same time. Furthermore, cleaning can only be done one at a time, resulting in low cleaning efficiency. Therefore, to solve the above defects, a phosphate cleaning device for steel plates can be designed. This phosphate cleaning device first performs phosphate cleaning on the steel plate, ensuring that the steel plate is clean in subsequent processes (cutting, welding, stamping, etc.). Summary of the Invention

[0003] The purpose of this invention is to provide a steel plate phosphating cleaning device that has the advantages of good cleaning effect after multiple cleanings and continuous cleaning that significantly improves cleaning efficiency.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a feeding mechanism, a cleaning mechanism, and a discharging mechanism are sequentially connected. The cleaning mechanism includes a first cleaning tank, a second cleaning tank, and a third cleaning tank, sequentially arranged on a supporting base plate. Two sets of drive components for transferring previously processed steel plates to subsequent cleaning tanks are spaced apart on the supporting base plate above the first, second, and third cleaning tanks. Each drive component includes two parallel, vertically placed picking plates, a connecting horizontal plate vertically fixed to the top of the picking plates, and a drive rod slidably connected to the connecting horizontal plate. A short rod is provided on the top side of the drive rod, and the short rod is slidably connected to a groove 1 outside the drive cylinder. The center of the upper end face of the drive cylinder is fixed to the bottom surface of the drive shaft. A drive gear is sleeved on the upper end of the drive shaft. The drive gear is an incomplete gear. Fixed racks 1 and 2 are symmetrically arranged on the support frames on both sides of the drive gear. The drive gear can intermittently mesh with racks 1 and 2.

[0005] A further provision of the present invention is that the first chute comprises two chute segments connected in the same order, the chute segments comprising a descending segment, a horizontal segment one, an ascending segment, and a horizontal segment two.

[0006] By adopting the above technical solution, cleaning tank 1, cleaning tank 2, and cleaning tank 3 can respectively soak and degrease, and phosphate the steel plates that need to be cleaned. The combination of multiple steps can significantly improve the cleanliness after cleaning. Two sets of drive components are set up so that the first set of drive components, after picking up materials from the feeding mechanism and cleaning tank 1, slides towards the discharging mechanism, placing the steel plates from the two picking plates into cleaning tanks 1 and 2. The steel plates in the feeding mechanism are then moved for the first cleaning, and the steel plates after the first cleaning are moved for the second cleaning. When the picking plates of the first set of drive components are in the feeding mechanism and cleaning tank 1, the picking plates of the second set of drive components are simultaneously located in cleaning tanks 2 and 3. As the picking plates of the first set of drive components move, the picking plates of the second set of drive components transfer the steel plates from cleaning tanks 2 and 3 to cleaning tank 3 and the discharging mechanism, placing the steel plates after the second cleaning into the third cleaning. The steel plates after the third cleaning are then discharged through the discharging mechanism. When the drive shaft rotates counterclockwise, the steel plates are then removed from the tank. The short rod is engaged in the first chute, which is further divided into a descending section, a horizontal section one, an ascending section, and a horizontal section two. Therefore, when the driving cylinder rotates to the descending section, the driving rod (i.e., the material-collecting plate) descends and enters the cleaning tank to collect material. Subsequently, the short rod is in the horizontal section one, soaking in the cleaning tank. Then, the short rod is in the ascending section, lifted out of the cleaning tank. Finally, the short rod is in the horizontal section two. At this point, the toothed part of the driving gear meshes with the rack on one side, causing the driving gear to rotate counterclockwise, moving to the right, closer to the discharge mechanism. The short rod slides and then enters the next trough section, including the descending section, horizontal section one, ascending section, and horizontal section two, repeating the above process once more. This allows the steel plate to descend and be placed, while the unloaded material plate rises. At this point, the drive gear rotates to mesh with rack two. The drive gear rotates counterclockwise, and after meshing with rack two, it moves to the left, sliding closer to the unloading mechanism to complete the transfer of the steel plate. By setting two sets of drive components, each steel plate can be continuously and stably cleaned in multiple steps, ensuring a good cleaning effect and improving cleaning efficiency.

[0007] A further configuration of the present invention is as follows: the descending segment, the first horizontal segment, and the ascending segment occupy the same arc surface of the driving cylinder, each occupying 1 / 12 of the arc surface of the driving cylinder; the second horizontal segment occupies 1 / 4 of the arc surface of the driving cylinder; and the toothed portion of the driving gear occupies 1 / 4 of the arc surface of the driving gear.

[0008] By adopting the above technical solution, the central angle corresponding to the arc edge formed by the sum of the descending segment, the first horizontal segment, and the ascending segment is 90°. When the drive rod is located in the above three segments of the drive cylinder, the toothless part of the drive gear contacts rack one and rack two, thus realizing only the material picking or unloading process of the picking plate. When the drive rod is located in the second horizontal segment of the drive cylinder, the toothed part of the drive gear contacts rack one or rack two, and the drive gear drives the picking plate to translate, realizing the process of unloading after translation and returning to the initial position after unloading.

[0009] A further feature of the present invention is that each of the first, second, and third cleaning tanks is provided with a stirring mechanism, the stirring mechanism including a stirring shaft, the number of stirring shafts being three, which are evenly spaced and fixed on the periphery of the first rotating circular plate, the center of the first rotating circular plate being fixed with a stirring shaft, and the stirring shaft being rotatably connected to the periphery of the second rotating circular plate.

[0010] A further configuration of the present invention is as follows: the center of the second rotating circular plate is coaxially and fixedly connected to the output shaft of the second motor; a synchronous pulley is fixedly fitted over the stirring shaft located between the first rotating circular plate and the second rotating circular plate; a synchronous belt is fitted over the three synchronous pulleys; the first motor is fixedly fitted on the periphery of the second rotating circular plate; and the output shaft of the first motor passes through the second rotating circular plate and is coaxially and fixedly connected to the stirring shaft on one side.

[0011] By adopting the above technical solution, when the steel plate is placed in the cleaning tank, the first motor rotates, driving the first rotating disc to rotate, and the stirring shaft rotates. At the same time, the second motor rotates, and the second rotating disc rotates, so that the stirring shaft can revolve, increasing the stirring of the soaking solution in the cleaning tank, making the soaking solution flow, and enhancing the soaking effect of the steel plate.

[0012] A further configuration of the present invention is as follows: the feeding mechanism includes a carrier frame, the bottom surface of the carrier frame is provided with a through groove, a push block is slidably connected in the through groove, the bottom surface of the push block is connected to one end of a spring, the other end of the spring is connected to a hollow slider, the hollow slider is slidably connected to a slide rail supporting a vertical plate, a connecting rod is hinged to the side of the slider, the other end of the connecting rod is hinged to the supporting vertical plate, a slot is provided on the connecting rod, a rotating rod is slidably connected in the slot, and the rotating rod is coaxially and fixedly connected to the output shaft of the feeding motor.

[0013] By adopting the above technical solution, when multiple steel plates are placed in the carrier frame, the feeding motor rotates, driving the rotating rod to rotate. The rotating rod further drives the connecting rod to slide back and forth, that is, drives the hollow slider to slide back and forth on the slide rail, which can push the steel plate at the bottom of the carrier frame into the subsequent operation, realizing the intermittent and gradual feeding of individual steel plates.

[0014] A further feature of the present invention is that the side of the carrier frame is connected to the carrier platform via an inclined plate.

[0015] A further feature of the present invention is that the discharge mechanism includes discharge belts disposed on three sides of the cleaning tank.

[0016] By adopting the above technical solution, the thoroughly cleaned steel plate is transported to the next step via a discharge conveyor belt.

[0017] A further feature of the present invention is that stirring rods are provided at equal intervals on the stirring shaft.

[0018] By adopting the above technical solution, the stirring rod is designed to agitate the soaking solution, allowing the flowing soaking solution to come into greater contact with the steel plate, thereby improving cleaning efficiency and ensuring cleaning effect.

[0019] A further feature of the present invention is that a material-grabbing suction cup is provided on the bottom surface of the material-grabbing plate.

[0020] By adopting the above technical solution, the material suction cup can stably grip the steel plate.

[0021] The beneficial effects of this invention are: by setting two sets of drive components, it is possible to continuously and stably perform multi-step cleaning on each steel plate, which not only ensures the cleaning effect but also improves the cleaning efficiency. Attached Figure Description

[0029] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] An embodiment of a steel plate phosphating cleaning device, as shown in Figures 1-5, includes a feeding mechanism, a cleaning mechanism, and a discharging mechanism connected in sequence. The cleaning mechanism includes cleaning tank 1, cleaning tank 2, and cleaning tank 3 arranged sequentially on a supporting base plate 4. Two sets of drive components 5 are spaced apart on the supporting base plate 4 above cleaning tanks 1, 2, and 3 for transferring previously treated steel plates to subsequent cleaning tanks. Each drive component 5 includes two parallel vertically placed picking plates 501, a connecting horizontal plate 502 vertically fixed to the top of the picking plates 501, and a drive rod 503 slidably connected to the connecting horizontal plate 502. A short rod 504 is provided on the top side of the drive rod 503, and the short rod 504 is engaged and slidably connected to a groove 506 outside a drive cylinder 505. The center of the upper end face of the drive cylinder 505 is fixed to the bottom surface of a drive shaft 507. A drive gear 508 is sleeved on the upper end of the drive shaft 507. The drive gear 508 is an incomplete gear. Fixed racks 509 and 510 are symmetrically arranged on the support frames on both sides of the drive gear 508. The drive gear 508 can intermittently mesh with racks 509 and 510. The slide 506 includes two groove sections connected in the same sequence: a descending section, a horizontal section one, an ascending section, and a horizontal section two. Cleaning tanks 1, 2, and 3 can respectively soak, degrease, and phosphate the steel plates to be cleaned. The combination of multiple cleaning steps significantly improves the cleanliness after cleaning. Two sets of drive components 5 are provided. The first set of drive components 5 can slide close to the discharge mechanism after taking materials from the feeding mechanism and cleaning tank 1, placing the steel plates on the two picking plates 501 back into cleaning tanks 1 and 2. The steel plates in the feeding mechanism are then moved for the first cleaning, and the steel plates after the first cleaning are moved for the second cleaning.When the material-retrieving plate 501 of the first drive assembly 5 is in the feeding mechanism and the first cleaning box 1, the material-retrieving plate 501 of the second drive assembly 5 is simultaneously located in the second and third cleaning boxes 2 and 3. As the material-retrieving plate 501 of the first drive assembly 5 moves, the material-retrieving plate 501 of the second drive assembly 5 transfers the steel plates in the second and third cleaning boxes 2 and 3 to the third cleaning box 3 and the discharge mechanism. This allows the steel plates after the second cleaning to be placed in for the third cleaning. The steel plates after the third cleaning are then discharged through the discharge mechanism. When the drive shaft 507 rotates counterclockwise, the short rod 504 is engaged in the first slide 506, which is divided into a descending section, a horizontal section 1, an ascending section, and a horizontal section 2. Therefore, when the drive cylinder 505 rotates to the position of the short rod 504 in the descending section, the drive rod 503, i.e., the material-retrieving plate 501, descends and enters the cleaning box to retrieve the material. Subsequently, the short rod 504 is located in the horizontal section 1. The steel plate is soaked in the cleaning tank, and then the short rod 504 is in the rising section, lifted out of the cleaning tank. Finally, the short rod 504 is in the second horizontal section. At this time, the toothed part of the drive gear 508 meshes with the rack 509 on one side. The drive gear 508 rotates counterclockwise, sliding to the right, closer to the discharge mechanism. Then the short rod 504 enters the next trough section, the lowering section, the first horizontal section, the rising section, and the second horizontal section again, repeating the above process to lower the steel plate and release it. The material pick-up plate 501 rises unloaded. At this time, the drive gear 508 rotates to mesh with the rack 510. The drive gear 508 rotates counterclockwise, and after meshing with the rack 510, it drives itself to move to the left, closer to the unloading mechanism, completing the transfer of the steel plate. By setting two sets of drive components 5, each steel plate can be continuously and stably cleaned in multiple steps, which not only ensures the cleaning effect but also improves the cleaning efficiency.

[0031] Furthermore, the descending segment, horizontal segment one, and ascending segment occupy the same arc surface of the driving cylinder 505, each occupying 1 / 12 of the arc surface of the driving cylinder 505. Horizontal segment two occupies 1 / 4 of the arc surface of the driving cylinder 505. The toothed portion of the driving gear 508 occupies 1 / 4 of the arc surface of the driving gear 508. The central angle corresponding to the arc edge formed by the sum of the descending segment, horizontal segment one, and ascending segment is 90°. When the driving rod 503 is located on the driving cylinder 505... In the above three segments, the toothless part of the drive gear 508 contacts the rack 509 and rack 510, thus only realizing the material picking or unloading process of the picking plate 501. When the drive rod 503 is located in the second horizontal segment of the drive cylinder 505, the toothed part of the drive gear 508 contacts the rack 509 or rack 510, and the drive gear 508 drives the picking plate 501 to translate, realizing the process of unloading after translation and returning to the initial position after unloading.

[0032] Furthermore, each of the three cleaning tanks (1, 2, and 3) is equipped with a stirring mechanism. Each stirring mechanism includes three stirring shafts 6, evenly spaced and fixed to the periphery of the rotating circular plate 7. A stirring shaft is fixed at the center of the rotating circular plate 7. These stirring shafts are rotatably connected to the periphery of the rotating circular plate 8. The center of the rotating circular plate 8 is coaxially and fixedly connected to the output shaft of the motor 10. A synchronous pulley is fixedly fitted around the stirring shaft located between the rotating circular plates 7 and 8. Synchronous belts 11 are fitted around three synchronous pulleys. A motor 9 is fixed on the periphery of the rotating circular plate 8. The output shaft of the motor 9 passes through the rotating circular plate 8 and is coaxially and fixedly connected to the stirring shaft on one side. When the steel plate is placed in the cleaning tank, the motor 9 rotates, driving the rotating circular plate 7 to rotate. The stirring shaft 6 rotates on its own axis. At the same time, the rotating circular plate 8 rotates after the motor 10 rotates, and the stirring shaft 6 revolves, increasing the stirring of the soaking solution in the cleaning tank, making the soaking solution flow, and enhancing the soaking effect of the steel plate.

[0033] Furthermore, the feeding mechanism includes a carrier frame 12, with a through groove on the bottom surface of the carrier frame 12. A push block 13 is slidably connected in the through groove. The bottom surface of the push block 13 is connected to one end of a spring, and the other end of the spring is connected to a hollow slider 14. The hollow slider 14 is slidably connected to a slide rail 16 supporting the vertical plate 15. A connecting rod 17 is hinged to the side of the slider, and the other end of the connecting rod 17 is hinged to the supporting vertical plate 15. A slot is provided on the connecting rod 17, and a rotating rod 18 is slidably connected in the slot. The rotating rod 18 is coaxially fixedly connected to the output shaft of the feeding motor. When multiple steel plates are placed in the carrier frame 12, the feeding motor rotates, driving the rotating rod 18 to rotate. The rotating rod 18 further drives the connecting rod 17 to slide back and forth, that is, drives the hollow slider 14 to slide back and forth on the slide rail 16, thus pushing the steel plate at the bottom of the carrier frame 12 into subsequent operations, realizing the intermittent and gradual feeding of a single steel plate.

[0034] Furthermore, the side of the carrier frame 12 is connected to the carrier platform 19 via an inclined plate.

[0035] Furthermore, the discharge mechanism includes a discharge belt 20 located on the side of the cleaning tank 3. The fully cleaned steel plate is output and transported to the next step via the discharge belt 20.

[0036] Furthermore, stirring rods are evenly spaced on the stirring shaft 6. The stirring rods are used to agitate the soaking solution, so that the flowing soaking solution has more contact with the steel plate, thereby improving cleaning efficiency and ensuring cleaning effect.

[0037] Furthermore, a material-grabbing suction cup 21 is provided on the bottom surface of the material-grabbing plate 501, which stably grips the steel plate.

[0038] Working principle of a steel plate phosphating and cleaning device:

[0039] Cleaning tank 1, cleaning tank 2, and cleaning tank 3 can respectively soak and degrease, and phosphate the steel plates that need cleaning. The combination of multiple cleaning steps can significantly improve the cleanliness after cleaning. Two sets of drive components 5 are provided. The first set of drive components 5 can slide near the discharge mechanism after picking up materials from the feeding mechanism and cleaning tank 1, placing the steel plates on the two picking plates 501 back into cleaning tanks 1 and 2. The steel plates in the feeding mechanism are then moved for the first cleaning, and the steel plates after the first cleaning are moved for the second cleaning. When the picking plates of the first set of drive components 5... When 501 is in the feeding mechanism and cleaning box 1, at the same time, the picking plate 501 of the second set of drive components 5 is located in cleaning box 2 and cleaning box 3. When the picking plate 501 of the first set of drive components 5 moves, the picking plate 501 of the second set of drive components 5 transfers the steel plates in cleaning box 2 and cleaning box 3 to cleaning box 3 and the discharge mechanism. The steel plates after the second cleaning are just placed into the third cleaning. The steel plates after the third cleaning are then discharged through the discharge mechanism. When the drive shaft 507 rotates counterclockwise, because the short rod 504 is engaged in the slide groove 506, the slide... The trough 506 is further divided into a descending section, a horizontal section one, an ascending section, and a horizontal section two. Therefore, when the driving cylinder 505 rotates until the short rod 504 is in the descending section, the driving rod 503, i.e., the material-collecting plate 501, descends and enters the cleaning tank to collect material. Subsequently, the short rod 504 is in the horizontal section one, soaking in the cleaning tank. Then, the short rod 504 is in the ascending section, lifted out of the cleaning tank. Finally, the short rod 504 is in the horizontal section two. At this time, the toothed part of the driving gear 508 meshes with the rack 509 on one side, causing the driving gear 508 to rotate counterclockwise, moving to the right, i.e., closer to the discharge mechanism. The slide proceeds, and then the short rod 504 re-enters the next slot section, including the descending section, horizontal section one, ascending section, and horizontal section two, repeating the above process once more. This lowers the steel plate and releases it, while the material pick-up plate 501 rises unloaded. At this time, the drive gear 508 rotates until it meshes with the rack 2 510. The drive gear 508 then rotates counterclockwise, and after meshing with the rack 2 510, it drives itself to move to the left, i.e., to slide closer to the unloading mechanism, completing the transfer of the steel plate. By setting two sets of drive components 5, each steel plate can be continuously and stably cleaned in multiple steps, which not only ensures the cleaning effect but also improves the cleaning efficiency.
