Abstract

This invention relates to the field of steel wire galvanizing technology and discloses a pretreatment device for steel wire galvanizing, including a galvanizing bath. An adaptive scraping mechanism is arranged at one end of the galvanizing bath, and a recovery heating mechanism is arranged below the adaptive scraping mechanism. The adaptive scraping mechanism includes a mounting frame. As the scraping plate slides along an eccentric arc groove, it gradually pulls the folded spring at the bottom of the scraping plate to expand and deform. The scraping plate gradually extends from the arc-shaped rotating frame, ensuring that it remains in contact with the galvanized layer on the steel wire. The rotating scraping plate pushes the still-wet galvanizing liquid from the bottom surface of the steel wire back to the top surface, causing the galvanizing liquid accumulated on the top surface to flow again. This ensures that the thickness of the galvanized layer on both the upper and lower surfaces of the steel wire is as uniform as possible. By achieving uniform distribution of the galvanized layer thickness on the upper and lower surfaces of the steel wire through technical means, not only can the quality and durability of the product be improved, but production costs can also be effectively reduced.

Description

Technical Field

[0001] This invention relates to the field of steel wire galvanizing technology, and more specifically to a pretreatment device for steel wire galvanizing. Background Technology

[0002] Galvanized steel wire is carbon steel wire that has been galvanized on its surface using hot-dip galvanizing or electroplating methods. Its properties are the same as those of straightened and tempered steel wire. It can be used as unbonded prestressing tendons, but at least 200-300g of zinc must be plated per square meter. It is commonly used as parallel wire cables in cable-stayed bridges.

[0003] Chinese Patent CN114807807B discloses a pretreatment device for galvanizing steel wire. The replenishing flux is moved into a rotating shaft tube, and then from the rotating shaft tube into the treatment tank to mix with the flux in the treatment tank. By staying in the rotating shaft tube, the flux in the treatment tank adapts to its temperature, and the temperatures of the flux and the treatment tank are brought closer together through the heat conduction of the rotating shaft tube. The first stirring blade on the surface of the first rotating shaft rotates through a linkage mechanism, stirring the flux in the treatment tank, increasing its fluidity, and reducing rapid temperature changes of the flux near the rotating shaft tube. The replenishing flux inside the rotating shaft tube is then discharged from the rotating shaft tube through a moving liquid guiding mechanism. This effectively reduces the temperature difference between the flux in the treatment tank and the replenishing flux, preventing direct mixing from causing rapid temperature changes in certain areas of the flux, reducing the impact of flux temperature changes on the steel wire fluxing, and ensuring the effect of subsequent galvanizing processing of the steel wire.

[0004] When the above-mentioned steel wire galvanizing pretreatment device is used, when the steel wire is vertically lifted from the galvanizing bath, the galvanizing liquid attached to its surface will naturally flow downward under the action of gravity. This flow phenomenon causes the galvanizing liquid to accumulate in the bottom area of ​​the steel wire and eventually drip down, resulting in uneven distribution of the galvanized layer thickness. Specifically, the coating at the top of the steel wire is thinner and the coating at the bottom is thicker. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for the pretreatment of galvanized steel wire, which has advantages such as scraping the galvanizing liquid back onto the top surface, thus solving the problem of uneven galvanized layer thickness on the upper and lower surfaces of the steel wire.

The bottom end of the scraping plate is slidably connected to one end of the positive arc rotating frame.

[0011] As a preferred embodiment of the pretreatment device for galvanizing steel wire described in this invention, a fixing frame is fixedly connected to the lower surface of each of the two limiting plates, an arc-shaped frame is fixedly connected to the lower surface of the fixing frame, the two ends of the arc-shaped frame are fixedly connected to the bottom end of the mounting frame, an arc-shaped slider is fixedly connected to the surface of the arc-shaped rotating frame, and a matching groove is provided at the bottom end of the mounting frame, and the arc-shaped slider is slidably connected in the matching groove.

[0012] As a preferred embodiment of the pretreatment device for galvanizing steel wire according to the present invention, the alternating component includes a positioning shaft, which is fixedly connected to both sides of the arc-shaped rotating frame. A sliding rod is sleeved on the positioning shaft, and a storage cylinder is slidably connected to the top end of the sliding rod. A positive rack is fixedly connected to the top end of the storage cylinder, and the positive rack is slidably connected to the mounting frame.

[0013] As a preferred embodiment of the pretreatment device for galvanizing steel wire described in this invention, a limit slider is fixedly connected to one side of the positive rack, a transverse sliding groove is provided on one side of the mounting frame, a coordinating gear is rotatably connected to the mounting frame, a reverse rack is meshed on the lower surface of the coordinating gear, the reverse rack drives the lower reverse arc-shaped rotating frame to rotate, a support frame is fixedly connected to the top of the mounting frame, and a cooling cylinder is fixedly connected to the bottom of the support frame.

[0014] As a preferred embodiment of the pretreatment device for galvanizing steel wire described in this invention, the uniform component includes a lifting slider, which is fixedly connected to one end of the heating sleeve. The inner wall of the collection box is provided with a lifting groove, and the lifting slider is slidably connected in the lifting groove.

[0016] As a preferred embodiment of the pretreatment device for galvanizing steel wire described in this invention, a gate is fixedly connected to the bottom surface of the sliding frame, the gate is slidably connected to the inner wall of the collection box, sliding tracks are symmetrically opened on both sides of the collection box, and cylinders are provided at both ends of the blocking frame, the cylinders being fixedly installed on the collection box.

[0017] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0018] 1. As the scraper slides along the eccentric arc groove, it gradually pulls the folded spring at the bottom of the scraper to expand and deform. The scraper will gradually extend out from the positive arc rotating frame, so that the scraper is always in contact with the galvanized layer on the steel wire. The rotating scraper will push the still wet galvanized liquid on the bottom surface of the steel wire back to the top surface of the steel wire, so that the galvanized liquid flows down from the top surface of the steel wire again, so that the thickness of the galvanized layer on the upper and lower surfaces of the steel wire is as uniform as possible. By using technical means to achieve a uniform distribution of the galvanized layer thickness on the upper and lower surfaces of the steel wire, it can not only improve the quality and durability of the product, but also effectively reduce the production cost.

[0019] 2. By driving the arc-shaped slider on the positive arc rotating frame to slide along the matching groove, the positive arc rotating frame rotates 180° along the bottom of the mounting frame. The positive rack and the negative rack slide along the transverse groove and exchange positions, so that the positive arc rotating frame rotates from one side of the mounting frame to the other side, so that the positive arc rotating frame rotates to the same initial state as the negative arc rotating frame, and the negative arc rotating frame rotates to the same initial position as the positive arc rotating frame. Using multiple sets of alternating reciprocating methods to apply zinc plating solution helps to ensure that the thickness of the zinc plating layer is evenly distributed on the entire steel wire surface, thereby improving the consistency of corrosion resistance.

[0020] 3. The coordinated spring sheet compressed inside the heating sleeve will push the heating rod out of the heating sleeve under the reaction force. The extended heating rod will push the sliding block to slide along the inclined groove, so that the height of the heating rod and the heating sleeve will also rise. By increasing the contact area between the heating rod and the galvanizing liquid, the heat transfer process can be accelerated, so that the galvanizing liquid can reach the required temperature more quickly, thereby improving production efficiency.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only 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.

[0034] The present invention will be further described below with reference to embodiments. Example 1

[0035] Reference Figures 1-3 and Figure 5This is the first embodiment of the present invention, which provides a device for pre-treatment of steel wire galvanization, including a galvanizing pool 100. An adaptive scraping mechanism 200 is arranged at one end of the galvanizing pool 100, and a recovery heating mechanism 300 is arranged below the adaptive scraping mechanism 200. The core function of the recovery heating mechanism 300 is to treat the residual galvanizing liquid dripping during the scraping process of the steel wire. Its heating logic is clearly distinguished from the conventional heating function of the galvanizing pool 100: the galvanizing pool 100 adopts an existing electric heating and insulation structure, which can maintain a large amount of galvanizing liquid in the pool in a molten state, meeting the basic requirements for steel wire galvanization. This application does not need to repeat the description of this conventional structure. The residual galvanizing liquid treated by the recovery heating mechanism 300 is small in quantity and dispersed. After leaving the galvanizing pool 100, its temperature drops rapidly, easily cooling and solidifying into clumps, and cannot flow back naturally. The heating sleeve 302 and the heating rod 303 are electrically heated, which can maintain the temperature of the recycled zinc plating solution at a molten state similar to that of the zinc plating solution pool 100, ensuring that it always remains liquid. When a certain amount is collected, it can be returned to the zinc plating solution pool 100 through the return pipe for reuse.

[0036] Meanwhile, the complete process flow of steel wire galvanizing pretreatment is as follows: the external traction equipment transports the steel wire to the galvanizing bath 100 to complete the surface galvanizing, then to the adaptive scraping mechanism 200 to scrape the unsolidified coating, then to the recycling heating mechanism 300 to collect the galvanizing liquid dripping during the scraping process, and finally to the heated galvanizing liquid returning to the galvanizing bath 100 through the return pipe, forming a closed-loop production process.

[0037] The adaptive scraping mechanism 200 includes a mounting frame 201, with a positive arc rotating frame 202 rotatably connected to the bottom end of the mounting frame 201. A scraping plate 203 is provided at one end of the positive arc rotating frame 202. An adaptive component is provided between the positive arc rotating frame 202 and the scraping plate 203 for adhering to the galvanized layer on the surface of the steel wire. An alternating component is provided between the mounting frame 201 and the positive arc rotating frame 202 for pushing the galvanized liquid from the bottom surface of the steel wire back to the top surface from both sides.

[0038] The recycling heating mechanism 300 includes a collection box 301, with heating sleeves 302 slidably arranged on the inner wall of the collection box 301. A heating rod 303 is slidably connected to one end of the heating sleeve 302. A uniform component is provided between the heating sleeve 302 and the heating rod 303 for uniformly heating the zinc plating liquid collected in the collection box 301. A motor is installed in the mounting frame 201, and a detector is installed in the collection box 301, both driven by a controller. A wire traction device is provided on one side of the zinc plating liquid pool 100 to pull the wire through the limit of the roller into the zinc plating liquid. Example 2

[0039] Reference Figures 1-8In the second embodiment of the present invention, a device for galvanizing steel wire is provided. The adapting component includes a limiting plate 204, which is symmetrically arranged at the bottom end of the mounting frame 201. A limiting groove is provided on one side of the limiting plate 204. A positive arc rotating frame 202 is slidably connected between the two limiting plates 204. The two sides of the scraping plate 203 slide along the limiting plate 204.

[0040] The limiting groove includes an eccentric arc groove 205, a vertical groove 206, and a concentric arc groove 207. The concentric arc groove 207 and the limiting plate 204 are at the same center. The eccentric arc groove 205 is located on one side of the concentric arc groove 207, and the center of the eccentric arc groove 205 is located below the center of the concentric arc groove 207. The depth of the eccentric arc groove 205 on the limiting plate 204 is deeper than that of the concentric arc groove 207. The tops of the eccentric arc groove 205 and the concentric arc groove 207 are connected by the vertical groove 206. The eccentric arc groove 205, the vertical groove 206, and the concentric arc groove 207 are connected end to end to form the eccentric arc groove 205, the vertical groove 206, and the concentric arc groove 207.

[0041] Both sides of the scraping plate 203 are fixedly installed with elastic sliding columns 208. The two elastic sliding columns 208 are slidably connected in the limiting slide groove. The bottom end of the scraping plate 203 is provided with a folding spring piece 209. The folding spring piece 209 is set on the inner wall of the positive arc rotating frame 202. The bottom end of the scraping plate 203 is slidably connected to one end of the positive arc rotating frame 202. The elastic sliding column 208 is composed of a sliding column and a sliding sleeve. An elastic element is provided between the sliding column and the sliding sleeve to push the sliding column at one end to slide along the limiting slide groove.

[0042] A fixing frame 210 is fixedly connected to the lower surface of each of the two limiting plates 204. An arc-shaped frame 211 is fixedly connected to the lower surface of the fixing frame 210. The two ends of the arc-shaped frame 211 are fixedly connected to the bottom end of the mounting frame 201. An arc-shaped slider 212 is fixedly connected to the surface of the arc-shaped rotating frame 202. A matching groove 213 is provided at the bottom end of the mounting frame 201. The arc-shaped slider 212 is slidably connected in the matching groove 213. The arc-shaped slider 212 has the same shape as the arc-shaped rotating frame 202 and is arc-shaped. The matching groove 213 has the same cross-sectional shape as the arc-shaped slider 212. The arc-shaped slider 212 fits and slides in the matching groove 213.

[0043] The alternating component includes a positioning shaft 214, which is fixedly connected to both sides of the arc-shaped rotating frame 202. A sliding rod 215 is sleeved on the positioning shaft 214. A storage tube 216 is slidably connected to the top of the sliding rod 215. A positive rack 217 is fixedly connected to the top of the storage tube 216. The positive rack 217 is slidably connected to the mounting frame 201.

[0044] A limiting slider 218 is fixedly connected to one side of the spur rack 217. A transverse groove 219 is provided on one side of the mounting bracket 201. The limiting slider 218 and the transverse groove 219 are in clearance fit. The limiting slider 218 can only slide horizontally along the length of the transverse groove 219, limiting its vertical and horizontal offset. This ensures that the overall movement trajectory of the spur rack 217 and the storage cylinder 216 remains horizontal, avoiding the generation of lateral torque during transmission. This ensures that the arc-shaped rotating frame 202 smoothly completes a 180° arc rotation along the matching groove 213. A coordinating gear 220 is rotatably connected to the mounting bracket 201. The lower surface of the coordinating gear 220 meshes with... The reverse rack 221 drives the lower reverse arc-shaped rotating frame 222 to rotate. The top of the mounting frame 201 is fixedly connected to the support frame 223, and the bottom of the support frame 223 is fixedly connected to the cooling cylinder 224. The reverse arc-shaped rotating frame 222 rotates in the opposite direction to the positive arc-shaped rotating frame 202. The structure on the reverse arc-shaped rotating frame 222 is the same as the structure on the positive arc-shaped rotating frame 202. Both the positive rack 217 and the reverse rack 221 are equipped with limit sliders 218. The number of mounting frames 201 disclosed is two sets. The actual number used depends on the actual use. The cooler installed in the cooling cylinder 224 can accelerate the solidification of the galvanized liquid on the steel wire.

[0045] Specifically, initially, when the positioning shafts 214 on both sides of the positive arc rotating frame 202 abut against the bottom end of the mounting frame 201, one end of the positive arc rotating frame 202 is located inside the mounting frame 201, while the other end is suspended outside the mounting frame 201. The two ends of the positive arc rotating frame 202 and the reverse arc rotating frame 222 on one side are aligned. The positive arc rotating frame 202 and the reverse arc rotating frame 222 are staggered and set on the mounting frame 201 at different positions. Furthermore, the rotation directions of the positive arc rotating frame 202 and the reverse arc rotating frame 222 are also opposite. The elastic sliding columns 208 on both sides of the scraping plate 203 are located at the bottom end of the eccentric arc groove 205.

[0046] The motor output within the mounting bracket 201 drives the coordinating gear 220 to rotate. The rotation of the coordinating gear 220 causes the meshing positive rack 217 and negative rack 221 on both sides to slide simultaneously. The positive rack 217 and negative rack 221, respectively, drive the positive arc-shaped rotating frame 202 and the negative arc-shaped rotating frame 222 to move via their respective storage cylinders 216 and sliding rods 215. When the positive rack 217 slides along the transverse groove 219 to the other end, it drives the sleeved positioning shaft 214 to move together via the bottom end of the sliding rod 215. Because the arc-shaped slider 212 on the surface of the positive arc-shaped rotating frame 202 slides within the fitting groove 213, the sliding rod 215 drives the positioning shaft 214... When the 14 moves, the stress will cause the positioning shaft 214 to rotate at the bottom end of the sliding rod 215, and the sliding rod 215 will retract into the storage cylinder 216, causing the arc-shaped slider 212 on the positive arc-shaped rotating frame 202 to slide along the matching groove 213, so that the positive arc-shaped rotating frame 202 rotates 180° along the bottom end of the mounting frame 201, and the positive rack 217 and the negative rack 221 slide and exchange positions along the transverse groove 219, so that the positive arc-shaped rotating frame 202 rotates from one side of the mounting frame 201 to the other side, so that the positive arc-shaped rotating frame 202 rotates to the same initial state as the negative arc-shaped rotating frame 222, while the negative arc-shaped rotating frame 222 rotates to the same initial position as the positive arc-shaped rotating frame 202;

[0047] During this process, as the arc-shaped rotating frame 202 drives the scraper plate 203 at one end to rotate along the bottom end of the mounting frame 201, the elastic sliding columns 208 on both sides of the scraper plate 203 will slide along the eccentric arc groove 205 because the eccentric arc groove 205 is deeper than the concentric arc groove 207 on the limiting plate 204. Since the galvanizing liquid on the steel wire will converge towards the bottom surface of the steel wire under the action of gravity, the galvanized layer on the bottom surface of the steel wire is thicker than that on the top surface. The scraper plate 203, along the eccentric arc groove 205... When the eccentric arc groove 205 slides, it will gradually pull the folded spring piece 209 at the bottom of the scraper plate 203 to expand and deform. The scraper plate 203 will gradually extend out from the positive arc rotating frame 202, so that the scraper plate 203 is always in contact with the galvanized layer on the steel wire. The rotating scraper plate 203 will push the galvanized liquid that is not yet dry on the bottom surface of the steel wire back to the top surface of the steel wire, so that the galvanized liquid flows down from the top surface of the steel wire again, so that the thickness of the galvanized layer on the upper and lower surfaces of the steel wire is kept as uniform as possible.

[0048] When the elastic sliding columns 208 on both sides of the scraper plate 203 slide to the top of the eccentric arc groove 205, the deformed folding spring 209 will pull the scraper plate 203 back into the positive arc rotating frame 202 under the reaction force. The elastic sliding columns 208 on both sides of the scraper plate 203 will slide from the vertical groove 206 at the top of the eccentric arc groove 205 to the top of the concentric arc groove 207. The scraper plate 203 will no longer contact the galvanized layer on the surface of the steel wire. At this time, the galvanized liquid pushed to the top surface will flow downward and diffuse again. When the motor output end drives the coordinating gear 220 to rotate in the opposite direction, the positive rack 217 will slide along the transverse groove. 219 Reverse sliding reset causes the positive arc rotating frame 202 to rotate and reset along the bottom end of the mounting frame 201. The elastic sliding columns 208 on both sides of the scraping plate 203 will slide along the concentric arc groove 207, sliding from the top end of the concentric arc groove 207 to the bottom end. When the elastic sliding columns 208 on both sides of the scraping plate 203 reach the intersection of the eccentric arc groove 205 and the concentric arc groove 207, the elastic sliding columns 208 will fall from the concentric arc groove 207 into the deeper eccentric arc groove 205, until the elastic sliding columns 208 slide back to the bottom end of the eccentric arc groove 205, so that the scraping plate 203 slides and resets to the bottom surface of the steel wire. Example 3

[0052] Specifically, initially, the output end of the cylinder 314 is in a fully extended state, the two ends of the coordinating spring 306 inside the heating sleeve 302 are in contact with the inner wall of the heating sleeve 302 and one end of the heating rod 303, the heating sleeve 302 and the heating rod 303 are located at the bottom of the lifting slide 305 and the inclined slide 308, and are blocked and limited by the lower surface of the blocking frame 309. At this time, the blocking column 310 is not in contact with the sliding frame 311, and the gate 312 is in a closed state.

[0053] As the galvanized liquid collected in the collection box 301 gradually covers the heating sleeve 302 and the heating rod 303, the level of the galvanized liquid in the collection box 301 continues to rise. When the output end of the cylinder 314 pulls the two ends of the stop frame 309 to slide along the sliding track 313, the height of the stop frame 309 changes as it slides from the bottom to the middle of the sliding track 313. Under the reaction force, the compressed coordinating spring 306 inside the heating sleeve 302 pushes the heating rod 303 out of the heating sleeve. The heating rod 303 extends out from inside 302 and pushes the sliding block 307 to slide along the inclined groove 308, so that the height of the heating rod 303 and the heating sleeve 302 also rises. When the blocking posts 310 at both ends of the blocking frame 309 contact the sliding frame 311, the output end of the cylinder 314 pushes the two ends of the blocking frame 309 to slide down along the sliding track 313, and then pushes the arranged heating sleeve 302 and heating rod 303 down, heating the zinc plating liquid in the collection box 301 in a reciprocating manner on one side.

[0054] When the monitor in the collection box 301 detects that the temperature of the galvanizing liquid is the same as that in the galvanizing liquid pool 100, the output end of the cylinder 314 pulls the baffle 309 to slide along the sliding track 313 to the top. When the baffle posts 310 at both ends of the baffle 309 come into contact with the surface of the sliding frame 311, the baffle posts 310 will push the sliding frame 311 to move along the sliding track 313 together, so that the gate 312 on the lower surface of the sliding frame 311 opens, and the heated galvanizing liquid is discharged back into the galvanizing liquid pool 100, and so on. Example 4

[0055] Reference Figures 1-10This is the fourth embodiment of the present invention. This embodiment aims to fully present the overall workflow of a pretreatment device for galvanizing steel wire, realizing the coordinated operation of uniformly scraping the galvanized layer of the steel wire and recycling the galvanizing solution. The specific steps are as follows:

[0056] First, initial state preparation is performed, that is, before the device is started, all components are in the preset initial position; at this time, the positioning shafts 214 on both sides of the arc-shaped rotating frame 202 of the scraping mechanism 200 abut against the bottom end of the mounting frame 201, one end of the arc-shaped rotating frame 202 is located inside the mounting frame 201, and the other end is suspended outside the mounting frame 201, the elastic sliding columns 208 on both sides of the scraping plate 203 are at the bottom end of the eccentric arc groove 205; the limiting slider 218 on one side of the positive rack 217 is embedded in the transverse sliding groove 219, and can only move along the... The slide rail slides horizontally to ensure the stability of the movement trajectory of the spur rack 217 and the storage cylinder 216; at the same time, the output end of the cylinder 314 of the recycling heating mechanism 300 is in a fully extended state, and the two ends of the coordinating spring 306 in the heating sleeve 302 are in contact with the inner wall of the heating sleeve 302 and one end of the heating rod 303. The heating sleeve 302 and the heating rod 303 are located at the bottom of the lifting slide rail 305 and the inclined slide rail 308 respectively, and are limited by the lower surface of the baffle 309, and the gate 312 remains in a closed state.

[0057] Following this, the galvanized layer of the steel wire undergoes a scraping and evening process. The complete pretreatment process for galvanizing the steel wire is as follows: the external traction equipment transports the steel wire to the galvanizing bath 100, then to the adapting scraping and evening mechanism 200, then to the recovery heating mechanism 300, and finally back to the galvanizing bath 100. After the steel wire completes galvanizing in the galvanizing bath 100, it is transported by the external traction equipment to the area below the adapting scraping and evening mechanism 200, which is located directly above the outlet of the galvanizing bath 100. At this time, the motor inside the mounting frame 201 starts, and the motor output drives the coordinating gear 220 to rotate, driving the meshing positive rack 217 and negative rack 221 to slide along the transverse slide groove 219. The positive rack 217 drives the positive arc-shaped rotating frame 202 to move through the storage tube 216, the sliding rod 215 and the positioning shaft 214. The arc-shaped slider 212 on the surface of the positive arc-shaped rotating frame 202 slides along the matching groove 213 to achieve 180° arc rotation. At the same time, the negative rack 221 drives the negative arc-shaped rotating frame 222 to rotate in the opposite direction, forming an alternating scraping action. During the rotation of the arc-shaped rotating frame 202, the elastic sliding columns 208 on both sides of the scraping plate 203 slide along the eccentric arc groove 205, pulling the folding spring piece 209 to expand and deform. The scraping plate 203 extends out from the arc-shaped rotating frame 202 and adheres to the surface of the steel wire, pushing the undried zinc plating liquid on the bottom surface of the steel wire to the top surface of the steel wire, so that the coating thickness is uniform. When the elastic sliding column 208 slides to the top of the eccentric arc groove 205, the folding spring piece 209 resets, pulling the scraping plate 203 to retract. The elastic sliding column 208 enters the concentric arc groove 207 through the vertical groove 206. The scraping plate 203 temporarily leaves the surface of the steel wire. When the coordinating gear 220 rotates in the opposite direction, all components reset and enter the next scraping cycle.

[0058] Simultaneously, the galvanizing solution is recovered and uniformly heated. During the scraping process, the dripping galvanizing solution falls into the collection tank 301 below. The galvanizing solution tank 100 adopts an existing electric heating and insulation structure to maintain the galvanizing solution in a molten state. After the recovered galvanizing solution leaves the tank, its temperature drops rapidly, requiring heating and insulation by the heating sleeve 302 and heating rod 303. When the galvanizing solution level in the collection tank 301 covers the heating sleeve 302 and heating rod 303, the temperature sensor inside the collection tank 301 triggers the heating element to start; at the same time, the output end of the cylinder 314 pulls the baffle 309 upward along the sliding track 313. After the baffle 309 rises, the coordinating spring 306 inside the heating sleeve 302 resets, pushing the heating rod 303 to extend out of the heating sleeve 302. The sliding block 307 slides along the inclined groove 308, causing the heating sleeve 302 and the heating rod 303 to rise and fall synchronously, changing the contact position between the heating element and the zinc plating liquid, avoiding temperature stratification, and ensuring that the temperature of the recycled zinc plating liquid is maintained in the molten state.

[0059] Finally, the galvanizing solution is returned and the device is reset. When the temperature sensor in the collection tank 301 detects that the temperature of the galvanizing solution is the same as the temperature in the galvanizing solution pool 100, and the liquid level sensor detects that the collection volume has reached the preset value, the output end of the cylinder 314 continues to pull the stop frame 309 to the top of the sliding track 313. At this time, the end face of the stop column 310 is in contact with the end face of the sliding frame 311, applying an axial pulling force to the sliding frame 311, causing the sliding frame 311 to rise along the sliding track 313. The gate 312 opens, and the heated galvanizing solution returns to the galvanizing solution pool 100 through the return pipe. Subsequently, the output end of the cylinder 314 extends, pushing the stop frame 309 down to the middle stroke. The stop column 310 contacts the side of the sliding frame 311 and applies vertical downward pressure, pushing the heating sleeve 302 and heating rod 303 to reset. The sliding frame 311 falls back, causing the gate 312 to close. The entire device returns to its initial state, waiting for the pretreatment of the next batch of steel wire.
