Description

Technical Field

[0001] The present invention belongs to the technical field of strip galvanizing, and particularly relates to an automatic strip galvanizing device. Background Art

[0002] As a narrow and long steel plate, strip steel is widely used in the production of welded steel pipes. Strip steel galvanizing is to coat a layer of zinc raw material on the surface of strip steel. The strip steel substrate and the plating solution undergo complex physical and chemical reactions to form a corrosion-resistant and tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the strip steel substrate, so it has strong corrosion resistance. The application effect of galvanized strip steel meets modern requirements and is now widely used as building materials. Galvanized strip steel has the characteristics of not rusting for many years and being corrosion-resistant. It can be free from the influence of external adverse environments and always maintain its own performance and appearance.

[0003] However, when the currently widely used traditional galvanizing equipment processes strip steel galvanizing, it faces a significant technical challenge, that is, it is difficult to effectively eliminate the bubbles generated on the surface of strip steel during the galvanizing process. Specifically, during the process of galvanizing the surface of strip steel by traditional galvanizing equipment, due to factors such as the possible surface unevenness, microscopic defects of the strip steel raw material itself or residues in the pretreatment process, when the zinc liquid contacts the strip steel, air is likely to be retained around these uneven areas. With the rapid cooling and solidification of the galvanized layer, these retained air is enclosed inside the coating to form bubbles. The presence of bubbles not only destroys the continuity and uniformity of the galvanized layer, but more critically, it weakens the bonding strength between the galvanized layer and the strip steel substrate, reduces the protective effect and service life of the galvanized layer. At the same time, the bubbles may also cause uneven defects on the surface of the galvanized layer, affecting the appearance quality and market acceptance of the product. Therefore, there are deficiencies and it cannot meet the production and use requirements of manufacturers. Thus, it is necessary to further improve.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide an automatic strip galvanizing device, with the expectation of achieving a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an automatic strip galvanizing device, which is achieved by the following specific technical means:

[0006] An automatic strip galvanizing device includes a frame, two conveying components arranged on the frame, and further includes a galvanizing component and a vibration mechanism arranged inside the frame;

[0007] There are two galvanized bases fixedly installed inside the frame. The galvanizing component is located between the two galvanized bases and is used for galvanizing the strip steel through the galvanizing component. The vibration mechanism is located above the left galvanized base and is used for vibrating and exhausting air during the strip steel galvanizing operation.

[0008] The vibration mechanism includes a vibration frame, and a channel for the movement of the strip steel is provided in the vibration frame. Fixed brackets are arranged on both the front and rear sides of the vibration frame. The side of the fixed bracket away from the vibration frame is fixedly connected to the inner wall of the frame. A fixing plate is fixedly installed on the side of the vibration frame facing the fixed bracket. Vibration springs are fixedly installed on both the upper and lower sides of the fixing plate, and the ends of the vibration springs away from the fixing plate are connected to the inner wall of the fixed bracket. Vibration components for vibrating the strip steel are provided on the upper and lower inner walls of the vibration frame, and air blowing components for cleaning impurities on the strip steel are provided on the front and rear inner walls of the vibration frame. The vibration frame drives the vibration components to vibrate up and down to exhaust air from the strip steel, and drives the air blowing components to clean the surface of the strip steel.

[0009] As a further description of the above technical solution: Through the cooperative action of the vibration mechanism and the knocking component, the vibration frame is caused to vibrate up and down under the action of the vibration spring, and the vibration components are used to drive the strip steel to shake, so that the strip steel generates a slight vibration frequency synchronously during galvanizing, thereby promoting the rapid and efficient detachment of the bubbles generated during the strip steel galvanizing process from the surface of the strip steel, effectively avoiding the galvanized layer defects caused by the retention of bubbles, and the vibration also promotes the microscopic contact between the zinc liquid and the surface of the strip steel, enhances the bonding force between the coating and the substrate, makes the coating more firm and durable, prolongs the service life of the strip steel product, and through this setting, not only the quality of the strip steel galvanized layer is optimized, the generation of defects is reduced, but also the production efficiency and product reliability are improved.

[0010] Further, the vibration component includes a vibration housing fixedly assembled on the inner wall of the vibration frame. A sliding block is slidably installed on the vibration housing. A vibration plate is fixedly installed on the outer side of the sliding block, and a cleaning cotton for cleaning dust on the surface of the strip steel is fixedly assembled on the side of the vibration plate away from the sliding block.

[0011] Among them, an elastic corrugated rubber ring is fixedly connected between the vibration plate and the outer wall of the vibration housing, and the elastic corrugated rubber ring is located on the outer periphery of the sliding block.

[0012] As a further description of the above technical solution: While the vibration component drives the strip steel to vibrate up and down, the cleaning cotton is used to contact the surface of the strip steel, and the cleaning cotton can effectively remove impurities such as tiny dust, oil stains, and rust adhering to the surface of the strip steel, making the impurities on the surface of the strip steel cleaned up, which is beneficial to the galvanizing of the strip steel.

[0013] Further, the vibration assembly further includes a cleaning airbag disposed inside the vibration housing. One side of the sliding block away from the vibration plate is fixedly assembled with a pressing plate for pressing the cleaning airbag, and an inflation valve for automatically inflating the cleaning airbag is provided on the inner wall of the vibration housing.

[0014] As a further description of the above technical solution: The automatic inflation of the cleaning airbag can be realized through the setting of the inflation valve, further improving its use effect.

[0015] Further, the blowing assembly includes a cleaning spray head fixedly assembled on the inner wall of the vibration frame. One side of the cleaning spray head is fixedly installed with a cleaning air pipe, and the end of the cleaning air pipe away from the cleaning spray head extends into the vibration housing and is connected to the cleaning airbag. The cleaning airbag is communicated with the cleaning spray head through the cleaning air pipe.

[0016] As a further description of the above technical solution: By jetting and cleaning the surface of the strip steel through the cleaning spray head, the tiny dust, oil stains and stubborn impurities attached to the surface of the strip steel can be deeply removed, ensuring extremely high cleanliness of the strip steel surface before galvanizing.

[0017] Further, a blowing hole is formed inside the cleaning spray head. The blowing hole includes a first hole channel and a second hole channel, and the inner diameter of the first hole channel is larger than that of the second hole channel.

[0018] As a further description of the above technical solution: Since the inner diameter of the first hole channel in the cleaning spray head is larger than that of the second hole channel, when the air flow passes through the smaller inner diameter of the second hole channel, the cross-sectional area gradually becomes smaller, and the flow velocity of the air flow will gradually increase, so as to effectively accelerate the flow velocity of the air flow, and further enhance the cleaning effect on the strip steel.

[0019] Further, the galvanizing assembly includes a galvanizing bath fixedly assembled inside the frame. A leveling roller is arranged inside the galvanizing bath, and fixing rings are fixedly assembled on both the front and rear sides of the leveling roller. Uniform blades for leveling the zinc liquid are fixedly installed on the fixing rings.

[0020] As a further description of the above technical solution: The uniform blades can drive the zinc liquid in the galvanizing bath to flow rapidly, thereby accelerating the fluidity of the zinc liquid and further enhancing the galvanizing effect on the strip steel.

[0021] Further, the conveying assembly includes a conveying seat fixedly assembled on the frame. A driving motor is arranged outside the conveying seat, and a conveying roller is rotatably installed inside the conveying seat. One side of the driving motor facing the conveying seat is fixedly connected to the conveying roller by a driving shaft;

[0022] Above the conveying roller, a correcting roller is provided. There is a transmission channel for the movement of the strip steel between the conveying roller and the correcting roller. The front and rear ends of the correcting roller are slidably connected to the conveying seat through correcting sliders, and an elastic support pad is connected between the upper side of the correcting slider and the conveying seat.

[0023] As a further description of the above technical solution: The automatic feeding of the strip steel is realized through the conveying roller. At the same time, the elastic force of the elastic support pad is used to push the correcting roller to always press against the surface of the strip steel, correct the bent strip steel, and press it flat, which is beneficial to the galvanizing operation of the strip steel.

[0024] Further, a transmission component is provided on the conveying component. The transmission component includes a first transmission gear disk fixedly assembled on the driving shaft, and a fixing frame fixedly assembled on the conveying seat. A second transmission gear disk is movably installed on the fixing frame. A transmission belt is provided between the first transmission gear disk and the second transmission gear disk. On the second transmission gear disk, a driving ratchet wheel is also fixedly assembled on the second transmission gear disk.

[0025] As a further description of the above technical solution: When the driving motor drives the conveying roller to feed the strip steel by means of the driving shaft, the driving shaft simultaneously drives the first transmission gear disk to rotate, and through the transmission action of the first transmission gear disk, the transmission belt and the second transmission gear disk, the driving ratchet wheel drives the driven ratchet wheel to rotate.

[0026] Further, a knocking component is provided on the vibration mechanism. The knocking component includes a rotating shaft rotatably assembled on the fixing bracket. A driven ratchet wheel is fixedly installed at the left end of the rotating shaft. The driven ratchet wheel is meshed with the driving ratchet wheel. A plurality of knocking pieces are provided on the rotating shaft, and the knocking pieces are located above the fixing plate.

[0027] As a further description of the above technical solution: By setting the knocking pieces in different directions, the knocking pieces can continuously knock and push the fixing plate, thereby strengthening the vibration frequency of the vibration frame.

[0028] Further, guide rollers for guiding the strip steel are provided inside both the machine frame and the galvanizing tank. An air knife for air cooling the strip steel after galvanizing is provided inside the machine frame.

[0029] As a further description of the above technical solution: After galvanizing is completed, the air knife is started through program control. The cold air is blown out at high speed by the air knife, so that the high-speed air flow impacts the surface of the strip steel, quickly blows off the excess zinc liquid on the surface of the strip steel. At the same time as the air flow takes away the excess zinc liquid, it also takes away the residual heat on the surface of the steel, thereby accelerating its cooling process, and then quickly cooling the galvanized strip steel, protecting the material performance and improving the work efficiency.

[0030] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0031] 1. For this strip steel automatic galvanizing equipment, through the combined action of the vibration mechanism and the knocking component, the rotating knocking part knocks and pushes the fixed plate, prompting the vibration frame to vibrate up and down under the action of the vibration spring, and the vibration component drives the strip steel to shake, so that the strip steel generates a slight vibration frequency synchronously during galvanizing, thereby promoting the rapid and efficient detachment of the bubbles generated during the strip steel galvanizing process from the strip steel surface, effectively avoiding the galvanized layer defects caused by the retention of bubbles, and the vibration also promotes the microscopic contact between the zinc liquid and the strip steel surface, enhancing the bonding force between the coating and the substrate, making the coating more firm and durable, extending the service life of the strip steel product, and through this setting, not only the quality of the strip steel galvanized layer is optimized, the generation of defects is reduced, but also the production efficiency and product reliability are improved.

[0032] 2. For this strip steel automatic galvanizing equipment, while the vibration component vibrates the strip steel up and down, it drives the air flow in the cleaning air bag to be transmitted along the cleaning air pipe to the cleaning nozzle, and the cleaning nozzle sprays the air flow at high speed towards the strip steel, thereby improving the cleaning effect of the cleaning nozzle on the impurities on the strip steel surface. And through the jet cleaning of the strip steel surface by the cleaning nozzle, it can deeply remove the tiny dust, oil stains and stubborn impurities attached to the strip steel surface, ensuring that the strip steel surface reaches a very high cleanliness before galvanizing. And through the synergistic effect of the air blowing component and the cleaning cotton, it effectively avoids the surface scratches or damages that may be caused by traditional mechanical cleaning, thereby effectively protecting the original surface quality of the strip steel, laying a solid foundation for the uniform adhesion and good combination of the subsequent galvanized layer, and at the same time realizing the efficient and non-destructive cleaning of the impurities on the strip steel surface, which has a significant positive impact on improving the product quality of galvanized strip steel, optimizing the production process, reducing production costs, etc. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating leveling blades 322 can drive the zinc liquid in the galvanizing tank 31 to flow quickly, thereby accelerating the fluidity of the zinc liquid and enhancing the galvanizing effect on the strip.

[0061] Please refer to Figures 1 to 3 , Figure 6, guide rollers 12 for guiding the strip are provided inside both the frame 10 and the galvanizing tank 31, and an air knife 13 for air-cooling the strip after galvanizing is provided inside the frame 10; after galvanizing is completed, the air knife 13 is started through program control, and cold air is blown out at high speed by the air knife 13 to prompt the high-speed air flow to impact the surface of the strip, quickly blow off the excess zinc liquid on the surface of the strip, and while the air flow takes away the excess zinc liquid, it also takes away the waste heat on the surface of the steel, thereby accelerating its cooling process, and then quickly cooling the galvanized strip, protecting the material properties and improving the work efficiency.

[0062] Please refer to Figures 7 to 8 , a knocking component 60 is provided on the vibration mechanism 50. The knocking component 60 includes a rotating shaft 61 rotatably assembled on the fixed bracket 52. A driven ratchet 62 is fixedly installed at the left end of the rotating shaft 61.

And because the knocking members 63 are arranged in different directions, the knocking members 63 can continuously knock and push the fixing plate 53, thereby strengthening the vibration frequency of the vibration frame 51.

[0063] Please refer to Figures 9 to 14 , the vibration assembly 55 includes a vibration housing 551 fixedly assembled on the inner wall of the vibration frame 51. A sliding block 552 is slidably installed on the vibration housing 551.

The inner diameter of the first hole channel 5631 is larger than that of the second hole channel 5632; since the inner diameter of the first hole channel 5631 in the cleaning nozzle 561 is larger than that of the second hole channel 5632, when the air flow passes through the smaller inner diameter of the second hole channel 5632, due to the gradually decreasing cross-sectional area, the flow velocity of the air flow will gradually increase, thereby effectively accelerating the flow velocity of the air flow and further enhancing the cleaning effect on the strip steel.

[0067] The specific usage mode and function of this embodiment:

[0068] Working principle: During use, the drive motor 22 is started through program control. The drive shaft 221 is used to drive the conveying roller 23 to rotate, and then the strip steel is driven to move through the conveying roller 23, realizing the automatic feeding of the strip steel. During the feeding process of the strip steel, the elastic support pad 242 uses its elastic force to push the straightening roller 24 to always press against the surface of the strip steel, straightening the bent strip steel and pressing it flat, which is beneficial to the galvanizing operation of the strip steel. When the strip steel passes through the galvanizing bath 31, the strip steel is galvanized using the zinc liquid in the galvanizing bath 31. At the same time as the strip steel passes through the galvanizing bath 31, the uniform roller 32 and the uniform blades 322 are driven to rotate synchronously based on the acting force when the strip steel contacts the uniform roller 32. The rotating uniform blades 322 can drive the zinc liquid in the galvanizing bath 31 to flow rapidly, thereby accelerating the fluidity of the zinc liquid and further enhancing the galvanizing effect on the strip steel. After galvanizing is completed, the air knife 13 is started through program control. The air knife 13 blows out cold air at high speed, causing the high-speed air flow to impact the surface of the strip steel, quickly blowing off the excess zinc liquid on the surface of the strip steel. At the same time as the air flow takes away the excess zinc liquid, it also takes away the residual heat on the surface of the steel, thereby accelerating its cooling process, and then quickly cooling the galvanized strip steel, protecting the material properties and improving work efficiency;

[0069] In addition, during the process of the drive motor 22 using the drive shaft 221 to drive the conveying roller 23 to feed the strip steel, the drive shaft 221 simultaneously drives the first transmission gear disk 41 to rotate. Through the transmission of the first transmission gear disk 41, the transmission belt 43, and the second transmission gear disk 42, the driving ratchet 45 drives the driven ratchet 62 to rotate. Then, the rotating shaft 61 is used to drive the knocking member 63 to rotate. The rotating knocking member 63 knocks and pushes the fixed plate 53, causing the vibration frame 51 to vibrate up and down under the action of the vibration spring 54. Since the knocking member 63 is arranged in different directions, the knocking member 63 can continuously knock and push the fixed plate 53, thereby strengthening the vibration frequency of the vibration frame 51. While the vibration frame 51 vibrates up and down, the vibration assembly 55 is used to drive the strip steel to shake, causing the strip steel to generate a slight vibration frequency synchronously during galvanizing, thereby promoting the bubbles generated during the galvanizing process of the strip steel to quickly and efficiently separate from the surface of the strip steel, effectively avoiding the galvanized layer defects caused by the retention of bubbles;

[0070] While the vibration assembly 55 drives the strip to vibrate up and down, the cleaning cotton 558 is in contact with the surface of the strip. Through the cleaning cotton 558, tiny dust, oil stains, rust and other impurities attached to the surface of the strip can be effectively removed, making the impurities on the strip surface cleaned up, which is beneficial to the galvanizing of the strip. Moreover, the cleaning cotton 558 can gently and thoroughly clean the strip surface, avoiding excessive damage to the base material, which is beneficial to maintaining the original mechanical properties and surface flatness of the strip, creating ideal conditions for subsequent galvanizing treatment. While the vibration plate 553 on the vibration assembly 55 drives the strip to vibrate up and down, the vibration plate 553 is pushed based on the reaction force when it contacts the strip, prompting the vibration plate 553 to squeeze the elastic corrugated rubber ring 555, and using the sliding block 552 to drive the extrusion plate 554 to squeeze the cleaning airbag 556, driving the air flow in the cleaning airbag 556 to be transmitted along the cleaning air pipe 562 to the cleaning nozzle 561. Since the inner diameter of the first channel 5631 in the cleaning nozzle 561 is larger than the inner diameter of the second channel 5632, when the air flow passes through the smaller inner diameter of the second channel 5632, due to the gradually decreasing cross-sectional area, the flow rate of the air flow will gradually increase, thus effectively accelerating the flow rate of the air flow, prompting the cleaning nozzle 561 to spray the air flow at high speed towards the strip, thereby improving the cleaning effect of the cleaning nozzle 561 on the impurities on the strip surface. And through the jet cleaning of the strip surface by the cleaning nozzle 561, the tiny dust, oil stains and stubborn impurities attached to the strip surface can be deeply removed, ensuring that the strip surface reaches a very high cleanliness before galvanizing. And through the synergistic effect of the blowing assembly 56 and the cleaning cotton 558, the surface scratches or damages that may be caused by traditional mechanical cleaning are effectively avoided, thus effectively protecting the original surface quality of the strip and laying a solid foundation for the uniform adhesion and good combination of the subsequent galvanized layer.
