[0034] The scooping mechanism includes a fixed frame 42, and a plurality of groups of circular holes 43 are provided at the bottom end of the fixed frame 42. The left and right sides of the fixed frame 42 are fixed to the connecting rod 41 by welding. The fixed frame 42 is designed in a trapezoidal shape so that the oxide layer can be concentrated at the bottom end of the fixed frame 42. The connecting rod 41 is inserted on the plug rod 37 away from the fixed frame 42. The bottom end of the plug rod 37 is welded and fixed to the protrusion 36. The protrusion 36 is fixed to the galvanizing tank 1 by welding. The outer side of the plug rod 37 is sleeved with a first spring 38. The top and bottom ends of the first spring 38 are welded and fixed to the connecting rod 41 and the protrusion 36 respectively. The bottom end of the connecting rod 41 away from the fixed frame 42 abuts against the fixed rod 34. The bottom end of the fixed rod 34 is welded and fixed to the second moving block 32. The second moving block 32 is threadedly connected to the second rotating rod 33.

[0035] The flip assembly includes a long rod 48, which is inserted into the interior of the moving rod 20, and the long rod 48 is welded and fixed to the moving rod 20. Gears 49 are welded and fixed on both the left and right sides of the long rod 48, and the gears 49 are meshed with racks 50. The racks 50 are welded and fixed on the inner wall of the galvanizing tank 1. The left and right sides of the long rod 48 are slidably connected in U-shaped chutes 51, and the U-shaped chutes 51 are opened on the inner walls of the left and right sides of the galvanizing tank 1.

[0036] During operation, the oxide layer on the surface of the zinc liquid is automatically scraped off by the rotating plate 23 on the bottom end of the moving rod 20 to reduce the input of manpower. When it is necessary to scrape off the oxide layer on the surface of the zinc liquid inside the galvanizing tank 1, the second rotating rod 33 is first driven to rotate by the driving motor 35, and the worm 31 connected to the top of the second rotating rod 33 will rotate synchronously. The worm 31 drives the worm wheel 30 to rotate by meshing with the worm wheel 30 during the rotation process. The worm wheel 30 is sleeved on the middle part of the first rotating rod 29, so the worm wheel 30 can drive the first rotating rod 29 to rotate inside the mounting shell 28. Since the threads on the left and right sides of the first rotating rod 29 have opposite rotation directions, the first moving blocks 26 threadedly connected to the left and right sides of the first rotating rod 29 will move in the opposite direction. During the movement of the first moving block 26, the connecting rod 25 connected to its top will be driven to move. The bottom end of the other side of the rod 25 is connected with the collar 24, and the collar 24 is sleeved on the connecting groove 21. Driven by the two groups of collars 24 on the left and right sides of the moving rod 20, the moving rod 20 can move on the surface of the galvanizing tank 1. During the movement of the moving rod 20, the rotating plate 23 at the bottom end thereof can scrape off the oxide layer on the surface of the zinc liquid and push the oxide layer to the front and rear sides of the galvanizing tank 1. Similarly, the reverse rotation of the driving motor 35 can move the moving rod 20 back to its original position. At this point, the operation of scraping off the oxide layer on the surface of the zinc liquid is completed. The side of the connecting rod 25 close to the first moving block 26 slides in the through groove 27 and keeps in contact with the inner wall of the through groove 27, so as to guide the first moving block 26 through the abutment between the connecting rod 25 and the inner wall of the through groove 27, thereby ensuring that the first moving block 26 can stably move on the first rotating rod 29.

[0037] Through the structural design of the scooping mechanism, after the rotating plate 23 scrapes off the oxide layer on the surface of the zinc liquid, the oxide layer will be pushed by the rotating plate 23 to gather on the front and rear sides of the galvanizing tank 1. At this time, by moving the fixed frame 42 upward, the oxide layer gathered on the front and rear sides of the galvanizing tank 1 can be salvaged for cleaning. While the driving motor 35 drives the worm 31 to rotate, the second moving block 32 threadedly connected to the second rotating rod 33 will also move upward. When the second moving block 32 moves, it will drive the fixed rods 34 fixed on its front and rear sides to rise synchronously. When the fixed rod 34 rises to the position of the bottom end of the connecting rod 41, the fixed rod 34 continues to move upward to push the connecting rod 41 to move upward, and the first spring 38 It will be stretched, and the other side of the connecting rod 41 is inserted into the inside of the galvanizing tank 1 and connected to the fixed frame 42. Therefore, when the connecting rod 41 moves upward, it will drive the fixed frame 42 to move upward, and the fixed frame 42 can scoop up the oxide layer. The fixed frame 42 is trapezoidal in design and has multiple groups of round holes 43 on the fixed frame 42, so that the zinc liquid can flow back to the inside of the galvanizing tank 1 through the round holes 43 to reduce the loss of zinc liquid. At this time, it is only necessary to scrape the oxide layer on the fixed frame 42. Since the rotating plate 23 is rotatably connected to the fixed plate 22, when the fixed frame 42 starts to move upward, the fixed frame 42 will not abut against the rotating plate 23 to ensure that the fixed frame 42 can smoothly return to its original position.

[0038] Through the structural design of the flipping assembly, the function of flipping the moving rod 20 when the moving rod 20 moves on the galvanizing tank 1 is realized. After a group of rotating plates 23 on the bottom end of the moving rod 20 scrapes off the oxide layer on the surface of the zinc liquid, an oxide layer will inevitably adhere to the rotating plate 23. The rotating plate 23 is flipped up to facilitate scraping and cleaning the attached oxide layer. In the process of the moving rod 20 driven by the ring 24, the gear 49 fixed on the long rod 48 will mesh with the rack 50 and rotate, so that the group of rotating plates 23 originally located at the bottom end of the moving rod 20 can be flipped up to facilitate scraping off the oxide layer attached to the rotating plate 23, so that the rotating plate 23 can be kept clean for the next scraping operation. Example

[0039] See also Figure 1 - Fig. 9 As shown, compared with Example 1, as another embodiment of the present invention, a first fixing hole 39 is opened on the side of the connecting rod 41 away from the fixing frame 42, a fixing column 44 is inserted in the first fixing hole 39, a ring 45 is welded and fixed on the fixing column 44, a side of the fixing column 44 away from the connecting rod 41 is inserted on the connecting rod 25, a side of the ring 45 away from the connecting rod 41 is welded and fixed with a second spring 46, a side of the second spring 46 away from the ring 45 is fixed to the connecting rod 25 by welding, and the second spring 46 is sleeved on the outer side of the fixing column 44;

[0040] During operation, when the connecting rod 41 drives the fixed frame 42 to move upward to the maximum height, in order to avoid pushing the connecting rod 41 downward to move when scraping the oxide layer in the fixed frame 42, the fixed column 44 inserted on the connecting rod 25 is inserted into the first fixing hole 39, and the fixing column 44 is abutted against the inner wall of the first fixing hole 39 to prevent the connecting rod 41 from moving downward. A second spring 46 is sleeved on the fixing column 44, so that the fixing column 44 can slide in the connecting rod 25 to avoid interference between the fixing column 44 and the connecting rod 41 during the rising process.

[0041] The fixed plate 22 and the rotating plate 23 are both L-shaped, and the rotating plate 23 is provided with an inclined surface;

[0042] During operation, the fixed plate 22 and the rotating plate 23 are both L-shaped. When the moving rod 20 returns to its original position, the two sets of rotating plates 23 will contact each other to ensure that the rotating plates 23 can scrape off the oxide layer on the entire surface of the zinc liquid, avoiding dead angles between the two sets of moving rods 20. In addition, a slope is provided on the bottom end of the rotating plate 23 to better scrape off the oxide layer on the surface of the zinc liquid.

[0043] The rotating plate 23 is provided with a mounting groove 56, and a counterweight 55 is welded and fixed inside the mounting groove 56;

[0044] During operation, the counterweight block 55 is fixed inside the mounting groove 56. The design of the counterweight block 55 allows a set of rotating plates 23 at the bottom to quickly rotate to the correct position under the action of gravity, so as to scrape off the oxide layer on the surface of the zinc liquid.

[0045] A second fixing hole 40 is formed at the top of the connecting rod 41, and the second fixing hole 40 is located directly above the insertion rod 37;

[0046] During operation, the second fixing hole 40 is located directly above the insertion rod 37. When the connecting rod 41 moves downward, the top portion of the insertion rod 37 can be inserted into the second fixing hole 40, so that the connecting rod 41 is fixed by the abutment between the insertion rod 37 and the inner wall of the second fixing hole 40, so that the connecting rod 41 can remain stable and will not shake easily.

[0047] A plurality of connecting columns 52 are inserted on the fixing rod 34, and the spacing between the plurality of connecting columns 52 is the same. The bottom ends of the connecting columns 52 are fixed to the supporting bottom plate 53 by welding, and the supporting bottom plate 53 is fixed to the galvanizing tank 1 by welding.

[0048] During operation, the top end of the connecting column 52 is inserted into the fixing rod 34 . When the fixing rod 34 rises or falls, the connecting column 52 ensures the stability of the fixing rod 34 during the movement.

[0049] The connecting rod 25 is designed in a U-shaped shape, and a supporting pulley 47 is welded and fixed to the middle of the connecting rod 25, and the supporting pulley 47 is in contact with the top of the galvanizing tank 1;

[0050] During operation, a support pulley 47 is fixed at the middle position of the connecting rod 25. The supporting pulley 47 slides on the galvanizing tank 1 to support the connecting rod 25, so that the connecting rod 25 can move more smoothly on the galvanizing tank 1.

[0051] Working principle: First, the hanger moves the processed metal parts to the top of the galvanizing tank 1. Since the surface of the zinc liquid inside the galvanizing tank 1 is in contact with the air for a long time, an oxide layer will inevitably be produced. In order to ensure that the metal parts will not contact the oxide layer, the second rotating rod 33 inside the mounting housing 28 is driven to rotate by starting the driving motor 35. The top of the second rotating rod 33 is connected to the worm 31. Therefore, when the second rotating rod 33 rotates, the worm 31 will also rotate synchronously. When the worm 31 rotates, it will drive the worm wheel 30 meshing with it to rotate, and the first moving blocks 26 threadedly connected to the left and right sides of the first rotating rod 29 will move in the opposite direction. In the process of gradually moving away from each other, the two groups of first moving blocks 26 will move in the opposite direction. Since the left and right sides of the moving rod 20 are connected together with the first moving block 26 through the collar 24 and the connecting rod 25, the two groups of moving rods 20 will gradually move away from each other. During the movement of the moving rod 20, the rotating plate 23 on the bottom end of the moving rod 20 can scrape off the oxide layer on the surface of the zinc liquid and push it to the front and rear sides of the galvanizing tank 1. At this time, the zinc liquid that has not been oxidized by the air can be exposed again, and then the metal parts are slowly placed into the interior of the galvanizing tank 1 through the hanger until the metal parts are completely submerged in the zinc liquid. After a period of time, the metal parts can be taken out of the zinc liquid. At this time, the drive motor 35 is started again to rotate it in the opposite direction, and the moving rod 20 will return to its original position for the next scraping operation.

[0052] When the oxide layer on the surface of the zinc liquid is pushed to the front and rear sides of the galvanizing tank 1 by the rotating plate 23, in order to prevent the oxide layer from continuing to accumulate on the surface of the zinc liquid, the connecting rod 41 will drive the fixed frame 42 to move upward, and the fixed frame 42 will be initially below the zinc liquid surface. When the fixed frame 42 moves upward, the oxide layer can be salvaged. The fixed frame 42 is designed as a trapezoid as a whole, so that the oxide layer can be concentrated at the bottom of the fixed frame 42, and the excess zinc liquid will flow back to the galvanizing tank 1 through the multiple groups of circular holes 43 opened on the fixed frame 42 to reduce the loss of zinc liquid. At this time, it is only necessary to scrape off the oxide layer in the fixed frame 42.

[0053] When the moving rod 20 is moving, a group of rotating plates 23 located at the bottom end will inevitably be attached with an oxide layer. When the moving rod 20 moves to the rack 50, the gear 49 can be engaged with the rack 50 to drive the moving rod 20 to rotate as a whole, so that the group of rotating plates 23 originally located at the bottom end of the moving rod 20 can be flipped upwards, and the group of rotating plates 23 originally located at the top end will rotate to the bottom end of the moving rod 20, so as to scrape off the oxide layer attached to the rotating plates 23, so that in the next scraping operation of the rotating plates 23, the oxide layer attached to the rotating plates 23 will not fall back into the galvanizing tank 1.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
