Description

Technical Field

[0001] This utility model relates to the field of galvanizing equipment technology, and in particular to a hot-dip galvanizing equipment. Background Technology

[0002] Galvanizing is a metal surface treatment process that primarily aims to coat the surface of metal products with a layer of zinc, thereby enhancing their corrosion resistance and aesthetics. Common methods in practice include hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing, as you mentioned earlier, involves immersing the metal product in molten zinc. Through a series of chemical reactions, zinc forms a zinc-iron alloy layer and a pure zinc layer on the metal surface. This effectively prevents corrosion of the metal substrate by air and moisture, making it suitable for large steel products and structural components.

[0003] A search revealed a hot-dip galvanizing apparatus disclosed in patent publication number CN213652614U. This apparatus includes a base plate with support frames fixedly connected to both its front and rear sides. A fixing block is fixedly connected to the middle of the upper, facing sides of the two sets of support frames. A sliding groove is formed on the lower side wall of each fixing block, which is slidably connected to a plate box. A motor is fixedly installed at the bottom of the plate box's inner cavity. By employing a double-headed motor, gears, and partitions, the plate box can move left and right, allowing workers to better hang and retrieve original parts.

[0004] The aforementioned technology only allows for vertical descent galvanizing of materials, preventing material rotation. During this vertical descent process, only a portion of the surface can fully contact the molten zinc. Areas with complex shapes, such as recesses and corners, may not receive sufficient zinc coverage, resulting in uneven galvanized layer thickness. This negatively impacts the product's corrosion resistance and aesthetics. The single vertical descent galvanizing method requires multiple adjustments to the material's position or repeated galvanizing operations to ensure the material meets galvanizing standards, significantly extending the galvanizing time for each piece. Furthermore, this technology only allows for material suspension. Suspension devices are ineffective for fixing irregularly shaped materials without suitable suspension points. For example, some blocky, sheet-like, and smooth-surfaced materials cannot be galvanized by suspension, severely limiting the types of materials that can be processed. Utility Model Content

[0005] The purpose of this invention is to provide a hot-dip galvanizing apparatus that solves the problems of the above-mentioned technologies, which only allow galvanizing of materials by vertical descent without rotation. During the vertical descent galvanizing process, only a portion of the surface can fully contact the molten zinc. For some complex-shaped materials, such as recesses and corners, it is difficult to obtain sufficient zinc coverage, resulting in uneven galvanized layer thickness, which affects the product's corrosion resistance and aesthetics. The single vertical descent galvanizing method requires multiple adjustments to the material position or repeated galvanizing operations to ensure that the material meets the qualified galvanizing standards, which greatly prolongs the galvanizing time for each piece of material. At the same time, the above-mentioned technologies can only suspend the material. Devices that can only suspend are difficult to fix materials with irregular shapes or without suitable suspension points, such as some blocky, sheet-like, and smooth-surfaced materials, which cannot be galvanized by suspension, severely limiting the types of materials that can be processed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot-dip galvanizing apparatus, comprising a housing and a processing mechanism disposed on the outer side of the end of the housing;

[0007] The processing mechanism includes a connecting plate, which is fixedly connected to the inner top of the housing. A support leg is fixedly connected to the lower surface of the housing. A first motor is installed on one side of the connecting plate. A gear is fixedly connected to the outer side of the main shaft of the first motor. A second motor is installed on the inner top of the housing. A rod sleeve is provided on one side of the second motor. A connecting rod is fixedly connected to one side of the rod sleeve. A clamping assembly is provided on the outer side of the end of the connecting rod. A galvanized box is provided below the clamping assembly.

[0008] In a preferred embodiment, a rotating shaft is fixedly connected to the outer side of the main shaft of the second motor. The rotating shaft is slidably connected to the inner side of the sleeve. A limit strip is fixedly connected to the outer side of the rotating shaft in an annular shape. A rectangular groove matching the limit strip is provided on the inner side of the sleeve.

[0009] In a preferred embodiment, the outer side of the gear is in contact with the outer surface of the sleeve.

[0010] In a preferred embodiment, the clamping assembly includes a clamping head, which is fixedly connected to the outer side of one end of the connecting rod. Four clamping blocks are slidably connected to the inner side of the end of the clamping head, and a gripper is fixedly connected to one side of each clamping block.

[0011] In a preferred embodiment, a limiting block is slidably connected to the inner side of one end of the clamping block, and the trapezoidal structure on the outer side of the end of the limiting block matches the trapezoidal through groove on the inner side of one end of the clamping block.

[0012] In a preferred embodiment, a rubber pad is fixedly connected to one side of the gripper.

[0013] In a preferred embodiment, a telescopic cylinder is installed on the inner side of the top of the clamping head, and one end of the telescopic cylinder is fixedly connected to one side of the limiting block.

[0014] In a preferred embodiment, a hook is fixedly connected to one side of the gripper.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In use, this utility model, by starting the first motor to drive the gear to rotate, and with the help of the ring tooth structure between the gear and the outer side of the rod sleeve, the rod sleeve can slide on the outside of the rotating shaft, causing the material held at the end of the connecting rod to move vertically downward and be accurately fed into the galvanizing box. This design can achieve stable and accurate material entry into the tank, reduce human operation errors, and improve production efficiency. Starting the second motor to drive the rotating shaft to rotate, and through the limit strip to drive the rod sleeve to rotate, so that the material on the outside of the end of the connecting rod rotates inside the galvanizing box. The material can come into full contact with the zinc liquid, achieving full galvanizing, effectively improving the uniformity and integrity of galvanizing, and improving product quality.

[0017] 2. In use, this utility model moves the limiting block by activating the telescopic cylinder. The trapezoidal structure on one side of the limiting block causes multiple clamping blocks to slide towards the center, which in turn causes the grippers on the outer side of the clamping block to clamp the material. The operation is simple and can quickly fix the material. It can adapt to the clamping needs of materials of different shapes and sizes, improve the convenience of operation, and hang the material on the inside of the hook for galvanizing. Four materials can be operated at the same time, which greatly improves the efficiency of galvanizing operations. Compared with galvanizing one by one, more materials can be galvanized in a shorter time, thus increasing production capacity. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a hot-dip galvanizing device, comprising: a housing 1, and a processing mechanism 2 disposed on the outer side of the end of the housing 1. The processing mechanism 2 includes a connecting plate 21, which is fixedly connected to the inner side of the top of the housing 1. A support leg 24 is fixedly connected to the lower surface of the housing 1. A first motor 22 is installed on one side of the connecting plate 21. A gear 23 is fixedly connected to the outer side of the main shaft of the first motor 22. A second motor 25 is installed on the inner side of the top of the housing 1. A sleeve 26 is provided on the side, and a connecting rod 27 is fixedly connected to one side of the sleeve 26. A clamping assembly is provided on the outer side of the end of the connecting rod 27. A galvanized box 28 is provided below the clamping assembly. A rotating shaft 29 is fixedly connected to the outer side of the main shaft of the second motor 25. The rotating shaft 29 is slidably connected to the inner side of the sleeve 26. A limit strip 210 is fixedly connected to the outer side of the rotating shaft 29 in an annular shape. A rectangular groove matching the limit strip 210 is opened on the inner side of the sleeve 26. The outer side of the gear 23 is in contact with the outer surface of the sleeve 26.

[0027] When using this device, the user can heat the zinc block inside the galvanizing box 28. The user can then fix the material to be galvanized using the clamping assembly. After fixing, the user starts the first motor 22, which drives the gear 23 to rotate. The gear 23 then contacts the annular tooth structure on the outside of the sleeve 26, causing the sleeve 26 to slide on the outside of the rotating shaft 29. This causes the material fixed by the clamping assembly at the end of the connecting rod 27 to move vertically downwards until it is fed into the galvanizing box 28 for galvanizing. Simultaneously, the user starts the second motor 25, which drives the rotating shaft 29 to rotate. This, in turn, causes the sleeve 26 to rotate via the limit bar 210, thus driving the connecting rod 27... The material on the outer side of the end rotates inside the galvanizing box 28 for thorough galvanizing. By starting the first motor 22, the gear 23 rotates. With the help of the ring tooth structure between the gear 23 and the outer side of the sleeve 26, the sleeve 26 can slide outside the rotating shaft 29, causing the material held at the end of the connecting rod 27 to move vertically downward and be accurately fed into the galvanizing box 28. This design can achieve stable and accurate material entry into the tank, reduce human operation errors, and improve production efficiency. Starting the second motor 25 drives the rotating shaft 29 to rotate, and through the limit bar 210, drives the sleeve 26 to rotate, causing the material on the outer side of the end of the connecting rod 27 to rotate inside the galvanizing box 28. The material can come into full contact with the zinc liquid, achieving thorough galvanizing, effectively improving the uniformity and integrity of galvanizing, and improving product quality.

[0028] like Figure 1 - Figure 5 As shown, the clamping assembly includes a clamping head 211, which is fixedly connected to the outer side of one end of the connecting rod 27. Four clamping blocks 212 are slidably connected to the inner side of the end of the clamping head 211. A gripper 213 is fixedly connected to one side of the clamping block 212. A limit block 214 is slidably connected to the inner side of one end of the clamping block 212. The trapezoidal structure on the outer side of the end of the limit block 214 matches the trapezoidal through groove on the inner side of one end of the clamping block 212. A rubber pad 216 is fixedly connected to one side of the gripper 213. The rubber pad 216 is made of rubber. A telescopic cylinder 215 is installed on the inner side of the top of the clamping head 211. The outer side of one end of the telescopic cylinder 215 is fixedly connected to one side of the limit block 214. A hook 217 is fixedly connected to one side of the gripper 213.

[0029] When the user places the material on one side of the telescopic clamping head 211, the telescopic cylinder 215 can be activated. The telescopic cylinder 215 drives the limiting block 214 to move, which in turn drives multiple clamping blocks 212 to slide towards the center through the trapezoidal structure on one side of the limiting block 214. This, in turn, causes the grippers 213 on the outer side of the clamping block 212 to clamp the material. At the same time, the rubber pad 216 can reduce damage to the material. When clamping is not required, the material can be hung on the inside of the hook 217 for galvanizing. By suspending the material, four pieces of material can be operated simultaneously. The telescopic cylinder 215 is activated to move the limiting block 214. The trapezoidal structure on one side of the limiting block 214 causes multiple clamping blocks 212 to slide towards the center, which in turn causes the grippers 213 on the outer side of the clamping block 212 to clamp the material. The operation is simple and can quickly fix the material. It can adapt to the clamping needs of materials of different shapes and sizes, improve the convenience of operation, and hang the material on the inside of the hook 217 for galvanizing. Four materials can be operated at the same time, which greatly improves the efficiency of galvanizing operations. Compared with galvanizing one by one, more materials can be galvanized in a shorter time, thus increasing production capacity.

[0030] Working Principle: When using this device, the user can heat the zinc block inside the galvanizing box 28. The user can then fix the material to be galvanized using the clamping assembly. After fixing, the first motor 22 is started, driving the gear 23 to rotate. The gear 23 then contacts the annular tooth structure on the outside of the sleeve 26, causing the sleeve 26 to slide on the outside of the rotating shaft 29. This causes the material fixed by the clamping assembly at the end of the connecting rod 27 to move vertically downwards until it is fed into the galvanizing box 28 for galvanizing. Simultaneously, the user can start the second motor 25, which drives the rotating shaft 29 to rotate. This, in turn, causes the sleeve 26 to rotate via the limiting bar 210, causing the material on the outside of the connecting rod 27 to rotate inside the galvanizing box 28, thus allowing the material to be galvanized.

[0031] For thorough galvanizing, the first motor 22 drives the gear 23 to rotate. The ring-shaped tooth structure between the gear 23 and the outer side of the sleeve 26 allows the sleeve 26 to slide outside the rotating shaft 29, causing the material held at the end of the connecting rod 27 to move vertically downwards and precisely feed into the galvanizing box 28. This design ensures stable and accurate material entry into the galvanizing tank, reducing human error and improving production efficiency. The second motor 25 then drives the rotating shaft 29 to rotate, which in turn drives the sleeve 26 to rotate via the limiting strip 210. This allows the material on the outer side of the connecting rod 27 to rotate inside the galvanizing box 28, ensuring all-around contact with the molten zinc for thorough galvanizing. This effectively improves the uniformity and integrity of the galvanizing process, enhancing product quality. When the user places the material on one side of the telescopic clamping head 211, the telescopic cylinder 215 can be activated. The telescopic cylinder 215 moves the limiting block 214, which in turn moves multiple clamps through the trapezoidal structure on one side of the limiting block 214. The holding block 212 slides towards the center, thereby driving the gripper 213 on the outer side of the clamping block 212 to clamp the material. At the same time, the rubber pad 216 can reduce damage to the material. When clamping is not required, the material can be hung on the inside of the hook 217 for galvanizing. Four materials can be operated at the same time by suspension. By activating the telescopic cylinder 215, the limiting block 214 is moved. The trapezoidal structure on one side of the limiting block 214 causes multiple clamping blocks 212 to slide towards the center, driving the gripper 213 on the outer side of the clamping block 212 to clamp the material. The operation is simple and can quickly fix the material. It can adapt to the clamping needs of materials of different shapes and sizes, improve the convenience of operation, and hang the material on the inside of the hook 217 for galvanizing. Four materials can be operated at the same time, which greatly improves the efficiency of galvanizing operation. Compared with galvanizing one by one, more materials can be galvanized in a shorter time, increasing production capacity.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
