Description

Technical Field

[0001] The invention relates to the technical field of steel plate production, and in particular to a high-efficiency hot-dip galvanized pickling plate surface treatment process and a device thereof. Background Art

[0002] In the metal processing industry, hot-rolled steel plates are important raw materials and are widely used in many fields such as automobiles, construction, and home appliances. In order to improve its corrosion resistance and aesthetics, the steel plates are often hot-dip galvanized. However, in the existing hot-dip galvanizing production process, the hot-rolled steel plates have significant operational complexity and low efficiency during the pickling and galvanizing process.

[0003] The traditional hot-dip galvanizing process for hot-rolled steel plates mainly includes the following steps: 1. Pickling in the pickling tank: The steel plate first enters the pickling tank, and the acid solution is used to remove the oxide scale, rust and other impurities on the surface to improve the adhesion of the galvanized layer; 2. Rinsing in the rinsing tank: The steel plate after pickling enters the rinsing tank to remove the residual acid to prevent adverse effects on the subsequent galvanizing process; 3. Surface drying: The steel plate needs to be dried after rinsing to ensure that the surface of the steel plate is dry to avoid bubbles or affect the quality of the coating during the galvanizing process; 4. Galvanizing in galvanizing pool: Finally, the dried steel plate enters the galvanizing pool, and a dense zinc layer is formed on the surface of the steel plate through the hot-dip galvanizing process to achieve the purpose of corrosion protection and aesthetics.

[0004] In the above process, the tanks are usually far apart, which means that workers need to use transfer vehicles to transfer steel plates after each operation. This operation method has the following significant problems: 1. Low work efficiency: Frequent transfer increases operation time and reduces overall production efficiency; 2. High labor intensity: Workers need to constantly carry steel plates, which is labor-intensive and poses safety risks; 3. Difficulty in quality control: New pollution and damage may be introduced during the transportation process, affecting the quality of the galvanized layer; 4. High equipment investment and maintenance costs: Multiple independent tanks and transfer equipment increase equipment investment and maintenance costs. Summary of the invention

[0005] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, the purpose of the present invention is to propose an efficient hot-dip galvanized pickling plate surface treatment process and a device thereof. The present invention realizes the integrated integration of key processes such as pickling, rinsing, drying and galvanizing by optimizing the process layout. This innovation not only greatly reduces the total cost of equipment investment and subsequent maintenance expenses, but also greatly improves the continuity and efficiency of the production process by eliminating unnecessary transfer steps. At the same time, it reduces the exposure and operation of materials during the transfer process, effectively reduces the risk of environmental pollution and product damage caused by transfer, thereby ensuring a significant improvement in production quality and enhanced stability.

When the self-clamping mechanism reaches the initial clamping point, it quickly and firmly clamps the steel plate, and then, under the continuous push of the first annular guide rail circulating conveying mechanism, the steel plate is carried through the pickling tank, the rinsing tank, the drying tank and the galvanizing tank in sequence; S3: Automatic unloading and repositioning: When the self-clamping mechanism carries the galvanized hot-rolled steel plates to the preset unloading area, the automatic release mechanism is triggered, and the steel plates fall smoothly onto the unloading conveying mechanism equipped with the integrated processing equipment. Subsequently, the unloading conveying mechanism is started to convey the first batch of processed steel plates to the specified direction, reserving space for subsequent steel plate processing and unloading operations; S4: Intelligent unloading system: Under the coordinated action of the unloading and conveying mechanism, the intelligent unloading robot accurately identifies and extracts the galvanized hot-rolled steel plates on the material holder, completes the unloading operation in a predetermined order, and realizes the intelligent closed loop of the entire pickling and galvanizing process, further improving the automation level and operation efficiency of the production line.

[0024] It should be noted that the intelligent loading robot (not shown in the figure) and the intelligent unloading robot (not shown in the figure) are respectively arranged on the outside of the loading conveying mechanism 31 and the outside of the unloading conveying mechanism 32.

[0025] Specifically, the pre-treated hot-rolled steel plates are efficiently, orderly and accurately loaded through the intelligent loading robot, and are placed one by one on the loading and conveying mechanism 31 in the integrated processing equipment 1. Subsequently, the loading and conveying mechanism 31 is started to smoothly and accurately convey the first batch of steel plates to the preset precise clamping position. The first ring guide rail circulating conveying mechanism 22 built into the integrated processing equipment 1 is activated, driving multiple groups of self-clamping mechanisms 23 to efficiently circulate along the track. When the self-clamping mechanism 23 reaches the initial clamping point, it quickly and firmly clamps the steel plate. Subsequently, under the continuous push of the first ring guide rail circulating conveying mechanism 22, the steel plate is carried through the pickling tank body 11, the rinsing tank body 12, the drying tank body 13 and the galvanizing tank body 14 in turn. When the self-clamping mechanism 23 carries the galvanized hot-rolled steel plate to the preset discharge area, the automatic release mechanism is triggered, and the steel plate falls smoothly onto the unloading conveying mechanism 32 equipped with the integrated processing equipment 1. Subsequently, the unloading The conveying mechanism 32 is started to convey the first batch of processed steel plates in the specified direction, reserving space for subsequent steel plate processing and unloading operations. Under the coordinated action of the unloading conveying mechanism 32, the intelligent unloading robot accurately identifies and extracts the galvanized hot-rolled steel plates on the material holder, and completes the unloading operation in a predetermined order, realizing the intelligent closed loop of the entire pickling and galvanizing treatment process, further improving the automation level and operation efficiency of the production line. During the operation of the first annular guide rail circulating conveying mechanism 22, the first annular guide rail circulating conveying mechanism 22 also synchronously drives the transmission component 42 to operate through the transmission rod 43. After receiving the synchronous power from the first annular guide rail circulating conveying mechanism 22, the transmission component 42 accurately controls the rinser 44 and the dryer 45 to perform efficient V-shaped trajectory motion inside the rinsing tank body 12 and the drying tank body 13, and maintains a constant and optimal set spacing with the steel plates entering their respective tank bodies to ensure rinsing and drying effects.

[0026] In one embodiment of the present invention, Figure 3 As shown, the self-clamping mechanism 23 includes a first lifting guide frame mechanism 231, a double clamping block mechanism 232 and a trigger gear rod 233, wherein the first lifting guide frame mechanism 231 is fixedly connected to the surface of the driving seat 221 in the first annular guide rail circulating conveying mechanism 22 and contacts with the V-shaped continuous track system 24, the double clamping block mechanism 232 is threadedly connected to the bottom of the first lifting guide frame mechanism 231, the trigger gear rod 233 is symmetrically fixedly connected to the inner wall of the fixed frame 21 and is located on the outside of the V-shaped continuous track system 24, and the double clamping block mechanism 232 is respectively connected to the two groups of trigger gear rods 233.

[0027] Specifically, the self-clamping mechanism 23 and its connection relationship are further explained. The first annular guide rail circulating conveying mechanism 22 is activated, driving multiple groups of self-clamping mechanisms 23 to circulate efficiently along the track. When the self-clamping mechanism 23 reaches the initial clamping point, the double clamping block mechanism 232 and the trigger gear rod 233 cooperate with each other to quickly and firmly clamp the steel plate. Then, under the continuous push of the first annular guide rail circulating conveying mechanism 22, one end of the first lifting guide frame mechanism 231 enters the V-shaped continuous track system 24, and drives the double clamping block mechanism 232 to rise and fall according to the shape of the V-shaped continuous track system 24. During the lifting process, the double clamping block mechanism 232 synchronously carries the steel plate through the pickling tank body 11, the rinsing tank body 12, the drying tank body 13 and the galvanizing tank body 14 in turn, and performs pickling, rinsing, drying and galvanizing operations, with good use effect.

[0028] In one embodiment of the present invention, Figure 5-Figure 6 As shown, the first lifting guide frame mechanism 231 includes a mounting seat 2311, a vertical limiting guide cylinder 2312, a vertical lifting rod 2313, a spring 2314 and a guide shaft 2315, wherein the mounting seat 2311 is fixedly connected to the surface of the driving seat 221 by bolts, the vertical limiting guide cylinder 2312 is fixedly connected to the inner wall of the mounting seat 2311, the vertical lifting rod 2313 is vertically slidably connected to the inner wall of the vertical limiting guide cylinder 2312, and one end of the vertical lifting rod 2313 passes through the vertical limiting guide cylinder 23 12, and a spring 2314 is fixedly connected to the surface of the mounting seat 2311, the other end of the vertical lifting rod 2313 passes through the bottom of the vertical limit guide cylinder 2312, and is threadedly connected to the double clamping block mechanism 232, the guide shaft 2315 is threadedly connected to the surface of one end of the vertical lifting rod 2313 passing through the bottom of the vertical limit guide cylinder 2312, and is slidably connected to the inner wall of the V-shaped continuous track system 24; the double clamping block mechanism 232 includes a clamping seat 2321, a first bidirectional reciprocating threaded screw 232 2. A first worm wheel 2323, a first worm 2324, a clamping block 2325 and a first driving gear 2326, wherein the clamping seat 2321 is threadedly connected to the surface of one end of the vertical lifting rod 2313 that passes through the bottom of the vertical limiting guide cylinder 2312, the first bidirectional reciprocating threaded screw 2322 is rotatably connected to the inner wall of the clamping seat 2321, the first worm wheel 2323 is fixedly connected to the center of the surface of the first bidirectional reciprocating threaded screw 2322, and the first worm 2324 is rotatably connected to the clamping seat 232 1 inner wall, and meshing with the first worm gear 2323, the clamping blocks 2325 are symmetrically slidably connected to the surface of the clamping seat 2321, one end of the two sets of clamping blocks 2325 respectively penetrate into the inside of the clamping seat 2321, and are threadedly connected to the outer surface of the first bidirectional reciprocating threaded screw 2322, the first driving gear 2326 is rotatably connected to the surface of the clamping seat 2321, and is fixedly connected to one end of the central axis of the first worm 2324, and the first driving gear 2326 is meshed with the teeth on the surface of the trigger gear rod 233.

[0029] It should be noted that in order to facilitate the clamping block 2325 to clamp and release the steel plate, the length of the steel plate needs to be greater than the length of the material seat.

[0030] Specifically, the structure and connection relationship of the first lifting guide mechanism 231 and the double clamping block mechanism 232 are further explained. When in use, when the double clamping block mechanism 232 moves to the initial clamping position, the two groups of clamping blocks 2325 on the clamping seat 2321 are in an open state and are respectively located on the top side and the bottom side of the steel plate. As the clamping seat 2321 continues to move, the first driving gear 2326 accurately contacts and smoothly meshes with the teeth on the surface of the trigger gear rod 233 on the left, and then the first driving gear 2326 immediately rotates synchronously, and the rotation of the first driving gear 2326 synchronously drives the first worm 2324 to rotate, and the first worm The rotation of rod 2324 synchronously drives the first worm gear 2323 and the first bidirectional reciprocating threaded screw 2322 to rotate. The rotation of the first bidirectional reciprocating threaded screw 2322 drives the two sets of clamping blocks 2325 to move inward synchronously. When the first driving gear 2326 is separated from the teeth on the surface of the trigger gear rod 233, the two sets of clamping blocks 2325 have clamped the steel plate and kept their positions unchanged. As the clamping seat 2321 moves forward steadily, the two sets of clamping blocks 2325 work together to firmly clamp and drive the steel plate to move smoothly out of the material seat of the feeding conveying mechanism 31. As the double clamping block mechanism 232 continues to move forward, the guide shaft 2315 accurately moves from the V-shaped continuous track system 24 The entrance enters the V-shaped continuous track system 24. During the movement of the guide shaft 2315 along the inner wall of the V-shaped continuous track system 24, the guide shaft 2315 is affected by the structure of the V-shaped continuous track system 24 and synchronously drives the vertical lifting rod 2313 to vertically lift along the inner wall of the vertical limit guide cylinder 2312. The lifting of the vertical lifting rod 2313 synchronously drives the lifting of the double clamping block mechanism 232, and synchronously drives the lifting of the steel plate, so that it successively enters the pickling tank 11, the rinsing tank 12, the drying tank 13 and the galvanizing tank 14 for pickling, rinsing, drying and galvanizing operations. When the galvanizing operation of the double clamping block mechanism 232 is completed and reaches the preset discharge area, the clamping seat 2321 is held. The first drive gear 2326 continues to move, and the first drive gear 2326 accurately contacts and meshes with the teeth on the surface of the trigger gear rod 233 on the right side, and then the first drive gear 2326 rotates synchronously.

[0040] Specifically, the structure and connection relationship of the bidirectional reciprocating parallel conveying mechanism 423 are further explained.
