Description

Technical Field

[0001] This application relates to the field of bolt galvanizing technology, and more specifically to a galvanizing device for bolts. Background Technology

[0002] When bolts are used, they may undergo rapid electrochemical corrosion due to exposure to air or prolonged exposure to humid or salty environments, which can lead to rust and affect their long-term service life.

[0003] After bolts are manufactured, bolt galvanizing technology is usually used to form a protective layer on the metal surface of the bolts, isolating the steel substrate inside the bolts from the external environment, thereby delaying the corrosion and rusting of the bolts. When galvanizing bolts, the bolts need to be collected, and the collected bolts are pickled to remove rust and treated with flux. Then they are put into molten zinc, so that the steel substrate reacts with zinc to form a zinc-iron alloy layer on the surface of the bolts, and then covered with a layer of pure zinc.

[0004] Referring to Chinese patent document CN219907814U entitled "A Bolt Surface Galvanizing Machine", this device uses the rotation of a zinc tank to make liquid zinc flow, which effectively solves the problem of low galvanizing effect at the bolt accumulation point, further improves the uniformity of galvanizing, thereby improving the galvanizing effect. In addition, the heating plate obstructs the flow direction of liquid zinc, making the flow direction of liquid zinc more irregular, so that the liquid zinc will hit the surface of the bolt, thereby further improving the galvanizing effect of the bolt.

[0005] Regarding the above technical solutions, when galvanizing the surface of bolts, the hot-dip galvanizing process requires immersing or retrieving the bolts from the zinc bath. During the retrieval process, the disturbance of the zinc bath causes some zinc dross remaining on the surface of the zinc bath to fall into the material frame and adhere to the surface of the bolts, affecting the quality of the bolts. Furthermore, during the process of immersing the bolts into the zinc bath, the zinc bath reacts rapidly with oxygen in the air to generate zinc oxide. As the bolts are immersed, the zinc oxide adheres to the surface of the bolts, preventing the zinc bath from making sufficient contact with the bolt substrate, resulting in discontinuous coatings or rough surfaces. Summary of the Invention

[0006] In view of this, this application provides a galvanizing apparatus for bolts, which aims to solve the problem that zinc oxide on the surface of the galvanizing bath adheres to the surface of the bolts during galvanizing.

[0007] This application provides a galvanizing device for bolts, comprising a galvanizing bath and a sliding plate slidably connected to the galvanizing bath; an adjusting plate is slidably connected to the sliding plate, a disturbance plate is fixedly connected to the adjusting plate, a disturbance gear is rotatably connected to one end of the disturbance plate near the adjusting plate, and two disturbance gears are provided; a connecting block is fixedly connected to the eccentric end of the disturbance gear, a disturbance block is rotatably connected to the connecting block, a flipping rod is rotatably connected to the disturbance block, and a collecting frame is slidably connected to the flipping rod, the collecting frame being used to load bolts that need to be galvanized.

[0008] During the process, the sliding plate slides along the galvanizing bath, driving the whole body to move. The adjusting plate slides on the sliding plate to fine-tune the position. When the disturbance gear rotates, it drives the connecting block to make a circular motion through the eccentric structure, which in turn drives the disturbance block and the flipping rod to produce complex disturbance actions, so that the collection frame disperses the zinc oxide on the surface of the zinc liquid in the galvanizing bath. The collection frame slides on the flipping rod and swings with it, so that the internal bolts are fully turned over, thereby achieving uniform galvanizing.

[0009] By driving the tilting rod and the collection frame to rotate continuously through the perturbed gear, the bolts in the collection frame are constantly tumbling and agitated during the galvanizing process. This ensures that all surfaces of the bolts can fully contact the molten zinc, avoiding uneven coating caused by accumulation or stillness, and significantly improving the uniformity and coverage quality of the galvanizing.

[0010] Optionally, a flipping wheel is fixedly connected to the end of the flipping rod away from the collection frame, a locking block is fixedly connected to the flipping wheel, a locking groove is provided on the disturbance block, and a push spring is fixedly connected to the flipping rod. The push spring is used to push the collection frame to move toward the end closer to the flipping wheel.

[0011] Optionally, an abutment block is fixedly connected to the collection frame, and the abutment block is configured as a ramp. A shaking baffle is fixedly connected to the galvanizing tank, and the shaking baffle is provided with multiple inclined ramps. The shaking baffle can drive the collection frame to move up and down.

[0012] After galvanizing, excess molten zinc often adheres to the bolt surface, which can easily form zinc nodules or drips after cooling, affecting appearance and dimensional accuracy. By shaking the collection frame up and down, excess molten zinc on the bolt surface can be effectively shaken off, resulting in a more uniform and smooth coating and avoiding interference problems during subsequent processing or assembly.

[0013] Optionally, a connecting rod is fixedly connected to the collection frame, the connecting rod and the flipping rod are slidably connected, and a connecting spring is fixedly connected to the connecting rod. The connecting spring is used to push the collection frame to move toward the side away from the flipping rod.

[0014] Optionally, a disturbance motor is fixedly connected to the disturbance block, and a transmission gear is fixedly connected to the output shaft of the disturbance motor. The transmission gear is located at one end of the disturbance block near the adjustment plate, and the transmission gear meshes with the disturbance gear.

[0015] Optionally, an upward motor is fixedly connected to the sliding plate, and an upward lead screw is fixedly connected to the output shaft of the upward motor. The upward lead screw and the adjusting plate are connected by a threaded connection, and the upward lead screw can drive the adjusting plate to move up and down.

[0016] Optionally, a movable motor is fixedly connected to the galvanizing tank, and a movable lead screw is fixedly connected to the output shaft of the movable motor. The movable lead screw is connected to the sliding plate by a threaded connection, and the movable lead screw is used to drive the sliding plate to move in the horizontal direction.

[0017] Optionally, the side wall and bottom wall of the collection frame are provided with connecting ports, which are used to allow molten zinc to enter the collection frame.

[0018] Immersing the bolt in molten zinc while it is in continuous motion helps the zinc to better wet the bolt surface and form a strong coating. This dynamic zinc plating method effectively improves the adhesion between the coating and the bolt substrate, reducing the risk of coating peeling or flaking.

[0019] Optionally, the galvanizing pool is provided with a collection tank for collecting the bolts after soaking.

[0020] Optionally, a sensor is provided on the galvanizing bath to sense the position of the adjusting plate and adjust the position of the disturbance block according to the position of the adjusting plate.

[0021] By integrating dynamic disturbance, rotary immersion, precise shaking, and intelligent control, a comprehensive innovation has been achieved in the traditional hot-dip galvanizing process for bolts. Its core advantage lies in the fact that, through the revolution and rotation of the collection frame, combined with the real-time dispersion of the zinc oxide layer by the disturbance system and the powerful drive of the internal vortex, an unprecedentedly uniform, dense, and highly adhesive coating is formed on the surface of each bolt. This fundamentally solves the quality pain points of uneven coating, missed coating, and easy peeling in traditional processes. Simultaneously, the continuous operation of the automated process, the improved zinc liquid utilization rate, and the recovery of excess zinc liquid through precise shaking significantly improve production efficiency and substantially reduce overall costs.

[0022] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0023] 1. By driving the tilting rod and the collection frame to rotate continuously through the perturbed gear, the bolts in the collection frame are constantly tumbling and agitated during the galvanizing process, thereby ensuring that all surfaces of the bolts can fully contact the molten zinc, avoiding uneven coating caused by accumulation or stillness, and significantly improving the uniformity and coverage quality of galvanizing.

[0024] 2. Before and during galvanizing, the rotation of the collection frame disperses the zinc oxide layer on the surface of the molten zinc, preventing zinc oxide from hindering the contact between the molten zinc and the bolts. This design not only improves the efficiency of galvanizing but also reduces coating defects caused by zinc oxide impurities.

[0025] 3. It achieves "zinc vibration" treatment for galvanized bolts, which not only optimizes the coating quality and improves the product appearance, but also reduces zinc liquid consumption and subsequent processing difficulty, making the entire galvanizing process more refined and controllable, and is particularly suitable for production scenarios with high requirements for bolt surface quality.

[0026] 4. By integrating dynamic disturbance, rotary immersion, precise shaking, and intelligent control, a comprehensive innovation has been achieved in the traditional hot-dip galvanizing process for bolts. Its core advantage lies in the fact that, through the revolution and rotation of the collection frame, combined with the real-time dispersion of the zinc oxide layer by the disturbance system and the powerful drive of the internal vortex, an unprecedentedly uniform, dense, and highly adhesive coating is formed on the surface of each bolt. This fundamentally solves the quality pain points of uneven coating, missed coating, and easy peeling in the traditional process. Simultaneously, the continuous operation of the automated process, the improved zinc liquid utilization rate, and the recovery of excess zinc liquid through precise shaking significantly improve production efficiency and substantially reduce overall costs.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 1-7 The technical solutions of the embodiments of this application are clearly and completely described herein. All other embodiments obtained by those skilled in the art based on the described embodiments are within the scope of protection of this application.

[0036] like Figure 1 As shown, this embodiment provides a bolt galvanizing device including a galvanizing tank 1, a transverse sliding mechanism, a longitudinal sliding mechanism, a disturbance mechanism, and a tilting mechanism. The galvanizing tank 1 is set on a horizontal surface and is used to store molten zinc. The transverse sliding mechanism is used to move the bolts to be galvanized laterally, the longitudinal sliding mechanism is used to move the bolts to be galvanized vertically, the disturbance mechanism is used to store the bolts and disperse the zinc oxide on the surface of the galvanizing tank 1 before immersion, and the tilting mechanism is used to facilitate the collection of the galvanized bolts.

[0037] like Figure 1 As shown, the lateral sliding mechanism includes a sliding plate 2, a moving motor 21, and a moving screw 22. The sliding plate 2 is slidably connected to the galvanizing tank 1, the moving motor 21 is fixedly connected to the galvanizing tank 1, and the moving screw 22 is fixedly connected to the output shaft of the moving motor 21. The moving screw 22 is connected to the sliding plate 2 by a threaded connection, and the moving screw 22 is used to drive the sliding plate 2 to move in the horizontal direction.

[0038] When it is necessary to move the bolt horizontally, start the moving motor 21, so that the output shaft of the moving motor 21 rotates, which drives the moving lead screw 22 to rotate. The moving lead screw 22 drives the sliding plate 2, which is threaded to it, to move horizontally on the galvanizing tank 1.

[0039] like Figure 2As shown, the longitudinal sliding mechanism includes an adjusting plate 3, an upward moving motor 31, and an upward moving lead screw 32. The upward moving motor 31 is fixedly connected to the sliding plate 2, and the upward moving lead screw 32 is fixedly connected to the output shaft of the upward moving motor 31. The adjusting plate 3 is threadedly connected to the upward moving lead screw 32, and the upward moving lead screw 32 can drive the adjusting plate 3 to move upward after rotation.

[0040] When it is necessary to move the position of the adjustment plate 3, the upward motor 31 is started, causing the output shaft of the upward motor 31 to rotate, which in turn causes the upward lead screw 32 to rotate. The upward lead screw 32 drives the adjustment plate 3 to move up and down, thereby realizing the up and down adjustment of the adjustment plate 3.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the disturbance mechanism includes a disturbance plate 4, a disturbance gear 41, a connecting block 42, a disturbance block 43, a flipping rod 44, and a collection frame 45. The disturbance plate 4 is fixedly connected to the adjusting plate 3. The disturbance gear 41 is rotatably connected to the disturbance plate 4, and the disturbance gear 41 is located at one end of the disturbance plate 4 near the adjusting plate 3. There are two disturbance gears 41, and each of the two disturbance gears 41 is provided with a connecting block 42. The connecting block 42 is fixedly connected to the disturbance gear 41. The disturbance block 43 is rotatably connected to the connecting block 42. The flipping rod 44 is rotatably connected to the disturbance block 43. The collection frame 45 is slidably connected to the flipping rod 44, and the collection frame 45 is used to load bolts that need to be galvanized. The bottom wall and side wall of the collection frame 45 are provided with a connecting port 46, which is used to allow molten zinc to enter the collection frame 45.

[0042] When galvanizing the bolts is required, the two perturbed gears 41 are rotated simultaneously, causing the connecting block 42 to rotate and the perturbed block 43 to revolve. During the circular motion of the perturbed block 43, the flipping rod 44 and the collecting frame 45 are rotated. The upward moving motor 31 is started, causing the upward moving screw 32 to rotate, moving the adjusting plate 3 above the galvanizing tank 1. The moving motor 21 is then started, causing the sliding plate 2 to move to the galvanizing tank. At the location where zinc liquid exists in zinc bath 1, the upward motor 31 is reversed, causing the adjusting plate 3 to move downward. The collecting frame 45 located on the adjusting plate 3 moves to a position above the zinc liquid. During the rotation of the agitator gear 41, the collecting frame 45 disperses the zinc oxide on the surface of the zinc liquid in zinc bath 1. As it continues to move downward, the bolts are immersed in the zinc liquid. The zinc liquid enters the collecting frame 45 from the connecting port 46 to galvanize the bolts. During the galvanizing process, due to the continuous rotation of the collecting frame 45, multiple bolts are evenly contacted with the zinc liquid.

[0043] After galvanizing is completed, the rotation of the collection frame 45 causes the zinc oxide on the surface of the zinc bath 1 to be dispersed, and drives the adjusting plate 3 to move upward.

[0044] Among them, such as Figure 3 and Figure 4 As shown, a disturbance motor 8 is fixedly connected to the disturbance block 43, and a transmission gear 81 is fixedly connected to the output shaft of the disturbance motor 8. The transmission gear 81 is located at one end of the disturbance block 43 near the adjustment plate 3, and the transmission gear 81 and the disturbance gear 41 mesh.

[0045] When it is necessary to drive the disturbance gear 41 to rotate, the disturbance motor 8 is started, causing the output shaft of the disturbance motor 8 to rotate. When the output shaft of the disturbance motor 8 rotates, it drives the transmission gear 81 to rotate, causing the transmission gear 81 to drive the disturbance gear 41 to rotate, thus causing the disturbance block 43 and the collection frame 45 to rotate.

[0046] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the flipping mechanism includes a flipping wheel 5, a locking block 51, a locking groove 52, a push spring 53, and a collection groove 9. The flipping wheel 5 is fixedly connected to the flipping rod 44 and is located on the side of the flipping rod 44 away from the collection frame 45. The locking block 51 is fixedly connected to the flipping wheel 5. The locking groove 52 is opened on the disturbance block 43. The push spring 53 is fixedly connected to the flipping rod 44 and is located at the end of the flipping rod 44 near the collection frame 45. The end of the push spring 53 away from the flipping rod 44 is fixedly connected to the collection frame 45. The collection groove 9 is opened on the galvanizing tank 1.

[0047] After the bolts are galvanized, pull the rotating wheel 5 to move it, so that the rotating wheel 5 drives the locking block 51 to move out of the locking groove 52 on the disturbance block 43, and drives the rotating wheel 5 to rotate, so that the collection frame 45 rotates and the bolts located in the collection frame 45 fall into the collection groove 9.

[0048] like Figure 1 and Figure 3 As shown, a stop block 6 is fixedly connected to the collection frame 45, and the stop block 6 is set in the shape of a ramp. A shaking baffle 61 is fixedly connected to the galvanizing tank 1. The shaking baffle 61 is provided with multiple inclined ramps. The shaking baffle 61 can drive the collection frame 45 to move up and down. A connecting rod 7 is fixedly connected to the collection frame 45. The connecting rod 7 and the flipping rod 44 are slidably connected. A connecting spring 71 is fixedly connected to the connecting rod 7. The connecting spring 71 is used to push the collection frame 45 to move toward the side away from the flipping rod 44.

[0049] When the collection frame 45 moves horizontally, the abutment block 6 on the collection frame 45 abuts against the inclined platform on the shaking baffle 61, and after abutting, the abutment block 6 moves upward, causing the connecting rod 7 to slide on the flipping rod 44. After sliding, the connecting rod 7 moves away from the flipping rod 44 by the push of the connecting spring 71. During this up-and-down movement, the collection frame 45 shakes up and down. During this shaking, the bolts in the collection frame 45 shake, and during this shaking, excess zinc liquid adhering to the surface of the bolts falls off.

[0050] like Figure 1 As shown, a sensor 91 is installed on the galvanizing tank 1. The sensor 91 is used to sense the position of the adjustment plate 3 and adjust the position of the disturbance block 43 according to the position of the adjustment plate 3.

[0051] When the adjusting plate 3 undergoes vertical displacement due to the upward movement of the lead screw 32, the sensor 91 captures its position information and transmits it to the control system. The control system calculates the change in the contact depth between the adjusting plate 3 and the molten zinc according to a preset program, and generates a corresponding position compensation command for the disturbance plate 4. For example, when the adjusting plate 3 drives the collection frame 45 into the molten zinc, the sensor 91 detects that the adjusting plate 3 has moved downward. At this time, the control system drives the disturbance motor 8 to increase the speed of the transmission gear 81, so that the disturbance gear 41 drives the flipping rod 44 to enhance the flow intensity of the molten zinc and counteract the accumulation of oxide layer on the surface of the molten zinc caused by the increased immersion depth. When the adjusting plate 3 moves horizontally, the sensor 91 simultaneously detects the displacement and moves the lead screw 22 to link the lateral position of the disturbance plate 4, ensuring that the disturbance area of ​​the molten zinc always covers the position of the collection frame 45.

[0052] When in use, the movable motor 21 is started, causing the output shaft of the movable motor 21 to rotate, which drives the movable lead screw 22 to rotate. The movable lead screw 22 drives the sliding plate 2, which is threadedly connected to it, to move horizontally on the galvanizing bath 1.

[0053] Start the upward moving motor 31, so that the output shaft of the upward moving motor 31 rotates, causing the upward moving lead screw 32 to rotate. The upward moving lead screw 32 drives the adjusting plate 3 to move up and down, thereby realizing the up and down movement adjustment of the adjusting plate 3.

[0054] When galvanizing bolts is required, the disturbance motor 8 is started, causing its output shaft to rotate. This rotation drives the transmission gear 81, which in turn drives the disturbance gear 41, causing the disturbance block 43 and the collection frame 45 to rotate. By driving the disturbance gear 41 to rotate, both gears rotate simultaneously. This rotation of the disturbance gear 41 drives the connecting block 42 to rotate, and causes the disturbance block 43 to revolve. During this circular motion, the disturbance block 43 drives the flipping rod 44 and the collection frame 45 to rotate. The upward moving motor 31 is then started, causing the upward moving screw 32 to rotate, moving the adjusting plate 3 above the galvanizing tank 1. Finally, the moving motor 21 is started, causing the sliding plate 2 to move onto the galvanizing tank 1. The zinc liquid is positioned so that the upward motor 31 reverses, causing the adjusting plate 3 to move downward. The collecting frame 45 on the adjusting plate 3 moves to a position above the zinc liquid. As the agitator gear 41 rotates, the collecting frame 45 disperses the zinc oxide on the surface of the zinc liquid in the galvanizing tank 1. As it continues to move downward, the bolts are immersed in the zinc liquid. The zinc liquid enters the collecting frame 45 from the connecting port 46 to galvanize the bolts. During the galvanizing process, due to the continuous rotation of the collecting frame 45, multiple bolts are evenly contacted with the zinc liquid.

[0055] After galvanizing is completed, the rotation of the collection frame 45 causes the zinc oxide on the surface of the zinc bath 1 to be dispersed, and drives the adjusting plate 3 to move upward.

[0056] When the collection frame 45 moves horizontally, the abutment block 6 on the collection frame 45 abuts against the inclined platform on the shaking baffle 61, and after abutting, the abutment block 6 moves upward, causing the connecting rod 7 to slide on the flipping rod 44. After sliding, the connecting rod 7 moves away from the flipping rod 44 by the push of the connecting spring 71. During this up-and-down movement, the collection frame 45 shakes up and down. During this shaking, the bolts in the collection frame 45 shake, and during this shaking, excess zinc liquid adhering to the surface of the bolts falls off.

[0057] After the bolts are galvanized, pull the rotating wheel 5 to move it, so that the rotating wheel 5 drives the locking block 51 to move out of the locking groove 52 on the disturbance block 43, and drives the rotating wheel 5 to rotate, so that the collection frame 45 rotates and the bolts located in the collection frame 45 fall into the collection groove 9.

[0058] The control system calculates the change in the contact depth between the adjustment plate 3 and the molten zinc according to a preset program, and generates a corresponding position compensation command for the disturbance plate 4. For example, when the adjustment plate 3 moves the collection frame 45 into the molten zinc, the sensor 91 detects that the adjustment plate 3 has moved downward. At this time, the control system drives the disturbance motor 8 to increase the speed of the transmission gear 81, so that the disturbance gear 41 drives the flipping rod 44 to enhance the flow intensity of the molten zinc and counteract the accumulation of oxide layer on the surface of the molten zinc caused by the increase in immersion depth. When the adjustment plate 3 moves horizontally, the sensor 91 simultaneously detects the displacement and moves the lead screw 22 to link the lateral position of the disturbance plate 4, ensuring that the disturbance area of ​​the molten zinc always covers the position of the collection frame 45.

[0059] In this embodiment, the present application achieves continuous removal of the oxide layer and active separation of zinc dross during the galvanizing process. The combined motion mode of the collection frame 45 ensures full contact between the molten zinc and the bolt surface, eliminating discontinuities in the coating. The centrifugal force generated by the tumbling motion removes the zinc dross instantly upon detachment from the molten zinc, avoiding the problem of difficult removal after solidification in traditional processes, and significantly improving the surface finish and corrosion resistance of the coating.

[0060] In this embodiment, the present application effectively solves the problems of zinc dross adhesion and discontinuous coating caused by positional displacement during the flipping and moving of the collection frame 45. The cooperation between the locking block 51 and the locking groove 52 constrains the vertical displacement of the collection frame 45, and the continuous pressing action of the push spring 53 eliminates the horizontal gap. The dual action ensures that the movement trajectory of the collection frame 45 in the zinc liquid is precise and controllable, avoids zinc liquid splashing and zinc oxide adhesion caused by mechanical vibration, and allows the bolt base to fully contact the zinc liquid to form a continuous and uniform coating.

[0061] In this embodiment, the present application generates controllable vibrations simultaneously during the movement of the collection frame 45, causing the zinc dross to separate from the bolt surface. Simultaneously, the vibrations break down the oxide layer on the zinc liquid surface, ensuring full contact between the zinc liquid and the base metal. This solution completes surface cleaning and coating optimization during the material transfer stage, avoiding secondary adhesion of zinc dross and coating defects caused by zinc oxide in traditional processes, thus improving coating continuity and surface smoothness.

[0062] In this embodiment, the present application can automatically adjust the working state of the disturbance plate 4 according to the actual position of the adjustment plate 3, so that the zinc liquid forms a directional flow during the immersion of the collection frame 45, effectively stripping the oxide layer on the surface of the zinc liquid and inhibiting zinc dross deposition. At the same time, the position compensation mechanism of the disturbance plate 4 avoids the zinc liquid flow blind zone caused by the movement of the adjustment plate 3, ensuring that the zinc liquid is in full contact with the bolt substrate to form a continuous and uniform coating.

[0063] The implementation principle of the bolt galvanizing device in this embodiment is as follows: The moving motor 21 is started, and its output shaft rotates, driving the moving lead screw 22 to rotate. Since the sliding plate 2 is threadedly connected to the moving lead screw 22, the rotational motion of the lead screw is converted into the linear motion of the sliding plate 2, causing the sliding plate 2 to move horizontally above the galvanizing bath 1 to a preset working position.

[0064] Start the upward moving motor 31, its output shaft rotates and drives the upward moving lead screw 32 to rotate. The adjusting plate 3 is threadedly connected to the upward moving lead screw 32, and the rotational motion of the lead screw is converted into the linear motion of the adjusting plate 3, thereby realizing the up and down movement adjustment of the adjusting plate 3 and its attached components.

[0065] The disturbance motor 8 is started, and its output shaft rotates, driving the transmission gear 81 to rotate. The transmission gear 81 meshes with the disturbance gear 41, thereby driving the two disturbance gears 41 to rotate synchronously. The rotation of the disturbance gear 41 causes the connecting block 42 connected to it to revolve, and this revolve motion is transmitted to the collection frame 45 through the flipping rod 44, causing the collection frame 45 to also revolve.

[0066] While the disturbance system is running, the upward motor 31 is started, driving the adjustment plate 3 to move above the galvanizing tank 1.

[0067] The moving motor 21 is activated, driving the sliding plate 2 precisely to the position in the galvanizing bath 1 containing molten zinc. The upward moving motor 31 is then reversed, causing the adjusting plate 3 to move the collecting frame 45 (containing bolts to be galvanized) downwards. During its revolution, the edges of the collecting frame 45 first contact and disperse the zinc oxide on the surface of the galvanizing bath 1. The adjusting plate 3 continues to move downwards, eventually ensuring that the bolts inside the collecting frame 45 are completely submerged in the molten zinc. The molten zinc enters the collecting frame 45 through the connecting port 46, making full contact with the bolt surface. Throughout the galvanizing process, the continuous revolution of the collecting frame 45 ensures that multiple bolts inside the frame can evenly contact the molten zinc, thus guaranteeing the uniformity of the galvanized layer.

[0068] After galvanizing, the upward motor 31 starts, driving the adjusting plate 3 and the collecting frame 45 upward to detach them from the molten zinc. During the lifting process, the continuous revolution of the collecting frame 45 helps to further disperse the zinc oxide on the surface of the molten zinc. The moving motor 21 starts again, driving the collecting frame 45, which is fitted with bolts, to move horizontally. During the movement, the abutment block 6 on the collecting frame 45 abuts against the inclined platform on the fixed shaking baffle 61. After abutting, the abutment block 6 is forced to move upward along the inclined platform, causing the connecting rod 7 connected to it to slide on the tilting rod 44. When the abutment block 6 slides past the highest point of the inclined platform, the connecting rod 7 quickly moves away from the tilting rod 44 under the elastic force of the connecting spring 71. This process causes the collecting frame 45 to shake up and down, thereby shaking off excess molten zinc adhering to the surface of the bolts.

[0069] After the excess zinc liquid on the surface of the bolts is removed, manually pull the tilting wheel 5. This action causes the tilting wheel 5 to disengage the locking block 51 from the locking groove 52 on the disturbance block 43, releasing the lock on the collection frame 45. Then, rotating the tilting wheel 5 will cause the collection frame 45 to tilt, pouring the galvanized bolts inside into the collection tank 9 below.

[0070] The control system calculates the change in the contact depth between the adjustment plate 3 and the molten zinc according to a preset program. When the sensor 91 detects that the adjustment plate 3 drives the collection frame 45 into the molten zinc, the control system drives the disturbance motor 8 to increase its speed, thereby increasing the speed of the transmission gear 81 and the disturbance gear 41. This enhances the revolution speed of the collection frame 45 driven by the flipping rod 44, thereby enhancing the flow intensity of the molten zinc and effectively counteracting the accumulation of oxide layer on the surface of the molten zinc caused by the increased immersion depth.

[0071] When sensor 91 detects that the adjustment plate 3 is moving horizontally, it simultaneously feeds the displacement data back to the control system. The control system drives the moving lead screw 22 to adjust the lateral position of the disturbance plate 4 in conjunction, ensuring that the disturbance area of ​​the zinc liquid always accurately covers the location of the collection frame 45, thus guaranteeing the continuity and effectiveness of the disturbance effect.

[0072] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
