Description

Technical Field

[0001] This utility model relates to the field of metal surface zinc plating technology, and in particular to a metal surface zinc plating device. Background Technology

[0002] Metals are prone to oxidation and corrosion in humid air and acidic or alkaline environments, which can lead to structural damage and performance degradation, making them unusable for extended periods and posing significant safety hazards during use. To address these issues, metal surface galvanizing technology is employed.

[0003] Metal surface galvanizing technology is a widely used surface treatment technology. Its purpose is to improve the performance and service life of metals by forming a zinc coating on the metal surface. The zinc coating will evenly cover the metal surface, forming a dense protective film that isolates the metal from external water, oxygen and corrosive substances, preventing them from directly contacting the metal surface, thereby slowing down corrosion. Therefore, metal surface galvanizing equipment can be used.

[0004] Current metal surface galvanizing equipment is divided into hot-dip galvanizing and cold galvanizing, with hot-dip galvanizing being more commonly used. Hot-dip galvanizing equipment includes a pretreatment system, a galvanizing system, a post-treatment system, and auxiliary systems. The galvanizing system further includes a galvanizing bath, heating equipment, hoisting equipment, and zinc dross treatment. During operation, parts pass through the pretreatment system and are then immersed in the molten zinc in the galvanizing bath for galvanizing. After a period of settling, the parts are removed and cooled by the post-treatment system. However, metal items of different specifications may be stacked, preventing sufficient contact between the metal surfaces and the molten zinc, resulting in incomplete galvanizing and reduced quality in subsequent metal processing.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, the controller turns on the dual-head motor, which drives the first synchronous pulley to rotate. Then, through the belt drive, the second synchronous pulley rotates simultaneously, causing the rotating shaft to drive the shelf to rotate in the zinc liquid. This allows the internal parts of the shelf to tumble, preventing the metal parts from stacking during galvanizing. At this time, the metal surface can fully contact the zinc liquid, allowing a uniform zinc layer to form on the surface of the parts, thus ensuring the quality of subsequent metal processing.

[0024] In this invention, the controller turns on the motor, which drives the gear to rotate and move it on the gear track. The fixed sleeve moves at the same time. Then, the telescopic rod moves the U-shaped scraper on the surface of the zinc bath. When the parts are galvanized in the zinc bath, a large amount of zinc dross will be generated on the surface of the zinc bath. The U-shaped scraper can scrape off the zinc dross on the surface of the zinc bath and collect it in the collection tank through the water tank. This makes the surface of the parts smooth and free of impurities when they are removed from the zinc bath, which improves the convenience of the device. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a metal surface galvanizing device, including a galvanizing tank 1, a rotating mechanism 2 fixedly connected to the bottom of the left and right sides of the outer wall of the galvanizing tank 1, the rotating mechanism 2 is used to facilitate the metal surface to fully contact the zinc liquid, and a cleaning mechanism 3 is fixedly connected to the top right side of the galvanizing tank 1, the cleaning mechanism 3 is used to facilitate the collection of zinc dross on the surface of the zinc liquid.

[0035] The rotating mechanism 2 includes a lifting frame 21 and a belt 28. The lifting frame 21 is fixedly connected to the outside of the galvanizing tank 1. A hydraulic rod 22 is fixedly connected to the top of the inner side of the lifting frame 21. A U-shaped frame 23 is connected to the bottom end of the hydraulic rod 22. This structure is used for lifting equipment. Protective shells 24 are fixedly connected to the left and right sides of the bottom of the U-shaped frame 23. A support frame 25 is fixedly connected between adjacent protective shells 24. A dual-head motor 26 is fixedly connected inside the support frame 25 to provide power to the equipment. The front and rear ends of the dual-head motor 26 are both connected to the belt. The protective shell 24 is fixedly connected to the synchronous pulley 27. The lower inner part of the two protective shells 24 is rotatably connected to the rotating shaft 210. The outer side of the two rotating shafts 210 is fixedly connected to the synchronous pulley 29. The two synchronous pulleys 29 are respectively connected to the corresponding synchronous pulley 27 through the belt 28. This mechanism drives the rotation of the lower shelf 211. The adjacent ends of the two rotating shafts 210 pass through the corresponding protective shell 24 and are fixedly connected to the same shelf 211. The rear top of the shelf 211 is rotatably connected to the iron frame cover 212.

[0036] Specifically, the controller 5 turns on the dual-head motor 26, which drives the rotation of the first synchronous pulley 27. Then, through the transmission of the belt 28, the second synchronous pulley 29 rotates simultaneously. This mechanism enables the first synchronous pulley 27 and the second synchronous pulley 29 to rotate simultaneously, so that the rotating shaft 210 drives the shelf 211 to rotate in the zinc bath 1, causing the parts inside the shelf 211 to tumble. In this way, the parts can rotate in the shelf 211, and the metal surface can fully contact the zinc liquid to form a zinc layer evenly, thereby ensuring the quality of subsequent metal processing.

[0037] Reference Figure 2 , Figure 5 and Figure 6 The cleaning mechanism 3 includes two support columns 31, which are fixedly connected to the front and rear ends of the top right side of the galvanizing tank 1, respectively. A hollow plate 32 is fixedly connected to the top of the two support columns 31. Sliding grooves 33 are provided on both the upper and lower sides of the hollow plate 32. A U-shaped sliding rod 34 is slidably connected inside the upper sliding groove 33. A motor 35 is fixedly connected to the right end of the U-shaped sliding rod 34. The output end of the motor 35 passes through the lower sliding groove 33 and is fixedly connected to a gear 36. A toothed rail 37 is fixedly connected to the bottom inside of the core plate 32. The toothed rail 37 meshes with the gear 36. This mechanism allows the motor 35 to slide on the hollow plate 32. A fixed sleeve 38 is fixedly connected to the left end of the U-shaped slide rod 34. The front side of the gear 36 passes through the lower sliding groove 33 and is rotatably connected to the fixed sleeve 38. A telescopic rod 39 is fixedly connected to the bottom of the fixed sleeve 38. A U-shaped scraper 310 is provided at the bottom end of the telescopic rod 39, which allows the U-shaped scraper 310 to slide back and forth on the surface of the zinc liquid.

[0038] Specifically, by turning on the control panel 5 to turn on the rotation of motor 35, the gear 36 on its left end will also rotate. When it rotates, it will slide on the gear rail 37, and at the same time drive motor 35 to slide in the lower sliding groove 33, so that the U-shaped slide rod 34 slides in the upper sliding groove 33. At the same time, the fixing sleeve 38 on the left end of the U-shaped slide rod 34 will also slide, and the telescopic rod 39 fixed on its bottom side can also slide, so that the U-shaped scraper 310 fixed at its bottom end will slide on the zinc liquid surface, thereby scraping off the zinc dross on the surface and avoiding many impurities on the surface of the parts.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A water tank 4 is fixedly connected to the top of the galvanizing tank 1. A water flow hole 9 is opened on the rear side of the interior of the water tank 4. This mechanism is used to collect zinc dross. A diversion plate 7 is fixedly connected to the front side of the interior of the water tank 4. Multiple diversion grooves 8 are opened at the top of the diversion plate 7. A collection tank 6 is fixedly connected to the rear side of the outer wall of the galvanizing tank 1. The inner size of the U-shaped scraper 310 matches the size of the fixed shelf 211. This mechanism is used to draw the zinc dross in the water tank 4 into the collection tank 6 for centralized collection.

[0040] Specifically, the U-shaped scraper 310 slides on the surface of the molten zinc, thereby scraping off the zinc dross. The zinc dross flows into the water tank 4, and the guide plate 7 causes the flowing molten zinc to flow to both sides through the guide channel 8. All the molten zinc eventually flows into the collection pool 6 through the water outlet 9 and is collected. This can avoid many impurities on the surface of the parts, and collecting zinc dross can also avoid wasting resources and reuse.

[0041] Reference Figure 2 , Figure 4 and Figure 6 The upper side of the shelf 211 is provided with an iron frame cover 212. The top right end of the iron frame cover 212 is fixedly connected with a latch 10. The iron frame cover 212 is rotatably connected to the shelf 211 through the latch 10. This mechanism is used to fix the shelf 211 and the iron frame cover 212 to prevent internal parts from falling. The middle right side of the outer wall of the lifting frame 21 is fixedly connected with a control panel 5. The control panel 5 is electrically connected to the dual-head motor 26 and motor 35 respectively. This mechanism is used to control the dual-head motor 26 and motor 35. The front right side of the U-shaped scraper 310 is threaded with a screw 311. The rear end of the screw 311 passes through the U-shaped scraper 310 and is threadedly connected to the telescopic rod 39, which facilitates the disassembly and replacement of the scraper.

[0042] Specifically, when using the device, the shelf 211 and the iron frame cover 212 are fixed by the latch 10 to prevent parts from falling off during use. The control panel 5 can control the operation of the device as needed, and the U-shaped scraper 310 can also be replaced and cleaned at any time.

[0043] Working principle: First, before use, the galvanizing tank 1 needs to be filled with zinc liquid for galvanizing. Then, put parts of different sizes into the rack 211. After putting them in, close the iron frame cover 212 and use the lock 10 to fix the rack 211 so that the parts inside the rack 211 cannot fall out. Then, use the hydraulic rod 22 in the middle of the bottom side of the lifting frame 21 to put the rack 211 into the galvanizing tank 1. Then, turn on the double-head motor 26 through the control panel 5. When the double-head motor 26 starts to rotate, it will drive the first synchronous wheel 27 at the front and rear ends to rotate. The belt 28 will also rotate. Then, the second synchronous wheel 29 will also rotate at the same time, and the shaft 210 on it will also rotate, so that the rack 211 rotates in the galvanizing tank 1. The parts inside will shake in the rack 211, which can make the surface of the parts fully galvanized. After galvanizing is finished, use the hydraulic rod 22 to pull up the rack 211 and open the lock 10 to take out the parts.

[0044] Furthermore, during galvanizing, the motor 35 can be turned on via the control panel 5, causing the gear 36 on its left end to rotate as well. As it rotates, it slides on the gear rail 37, simultaneously driving the motor 35 to slide in the lower sliding groove 33. This causes the U-shaped slide rod 34 to slide in the upper sliding groove 33. At the same time, the fixing sleeve 38 on the left end of the U-shaped slide rod 34 also slides, and the telescopic rod 39 fixed on its bottom side can also slide, causing the U-shaped scraper 310 fixed at its bottom end to slide on the surface of the molten zinc, thereby scraping off the zinc dross. The zinc dross will flow into the water tank 4, and the guide plate 7 will cause the flowing molten zinc to flow to both sides through the guide groove 8. All the molten zinc will eventually flow into the collection tank 6 through the water outlet 9 and be collected, thus avoiding the presence of many impurities on the surface of the parts.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
