Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment of galvanized steel strips, in particular to coating processing equipment for galvanized steel strips. Background Art

[0002] Galvanized steel strip is made by coating cold-rolled or hot-rolled, long, narrow steel strips with varying degrees of zinc and aluminum. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and long service life. A complex physical and chemical reaction occurs between the hot-dip galvanized steel strip substrate and the molten bath, forming a corrosion-resistant, tightly structured zinc-iron alloy layer. This alloy layer blends seamlessly with the pure zinc layer and the steel strip substrate.

[0003] A Chinese patent application (authorization announcement number: CN217628619U) discloses a galvanized steel strip surface treatment device, comprising a protective assembly for storing the galvanized steel strip to be treated; a support assembly located at the top of the protective assembly and slidably connected to the protective assembly; a drive assembly located on one side of one end of the top of the protective assembly; and a limit assembly located on one side of one end inside the protective assembly. The beneficial effect of the present invention is that when the first latch on the right side of the turntable moves to the left side of the turntable, the first latch directly engages with the second latch on the left side of the first linkage frame, generating an upward force to move the first linkage frame and the second linkage frame upward, thereby causing the first and second arc-shaped toggle plates to move the liquid inside the treatment tank up and down, causing the water flow to diffuse outward with the first and second arc-shaped toggle plates as the center, thereby improving the mixing effect of the purified liquid with the liquid inside the treatment tank.

[0004] However, in the actual application of this patented technology, the existing galvanized steel strip needs to be cleaned during the production process, and needs to be dried after cleaning. During the drying process, since the dryer is fixed and cannot be adjusted, it cannot be dried according to the size of the galvanized steel strip, which will affect the drying speed of the galvanized steel strip. At the same time, the conveying effect of the galvanized steel strip is poor during the cleaning process, thereby affecting the surface treatment speed of the galvanized steel strip.

[0027] As Figures 1 to 4 shown, this embodiment proposes a coating processing device for galvanized strip steel, including <>

[0028] an outer shell 1, a chassis 2, and a pair of inlet and outlet conveying rollers 3. The chassis 2 is fixed at the bottom of the outer shell 1, and the inlet and outlet conveying rollers 3 are installed on both sides outside the outer shell 1;

[0029] Surface treatment component 4 is arranged on the outer shell 1. The surface treatment component 4 includes a pair of clamping plates 4-1, and the clamping plates 4-1 are installed at both ends of the inner bottom of the outer shell 1. A connecting block 4-2 is rotatably connected between the clamping plates 4-1. A telescopic cylinder 4-3 is installed at the bottom of the outer shell 1, and the output end of the telescopic cylinder 4-3 is located inside the outer shell 1. A cross frame 4-4 is installed at the output end of the telescopic cylinder 4-3. Both ends of the surface of the cross frame 4-4 are rotatably connected with fixing plates 4-5 through pin shafts. An inclined roller 4-18 is rotatably connected between the fixing plate 4-5 and the connecting block 4-2. A driving motor 4-6 is installed on the surface of the fixing plate 4-5, and the output end of the driving motor 4-6 is connected to the inclined roller 4-18. A plurality of rotating seats 4-7 are arranged on the inner bottom surface of the outer shell 1, and a supporting roller 4-8 is rotatably connected inside the rotating seat 4-7. A cavity pipeline 4-9 is arranged on the side end surface of the fixing plate 4-5, and a connecting pipe 4-10 is arranged on the outer surface of the cavity pipeline 4-9. The connecting pipe 4-10 is located outside the outer shell 1. A plurality of flushing nozzles 4-11 are arranged at both the upper and lower ends of the side surface of the cavity pipeline 4-9. An air inlet pipeline 4-12 is installed on the side surface of the outer shell 1, and one end of the air inlet pipeline 4-12 is connected with a blowing hood 4-13. A plurality of air ports 4-14 are arranged on both opposite surfaces inside the blowing hood 4-13. A collecting groove 4-15 is opened at the inner bottom of the outer shell 1, and a discharge pipeline 4-16 is installed at the bottom of the outer shell 1. The discharge pipeline 4-16 is communicated with the collecting groove 4-15, and the lower end of the discharge pipeline 4-16 is connected with a recycling box 4-17.

[0030] In this embodiment, in order to achieve the conveying effect of cleaning and drying the surface of the strip steel, the surface treatment component 4 is designed. Two clamping plates 4-1 are fixed inside the outer shell 1, and a connecting block 4-2 is rotatably connected between the clamping plates 4-1. A telescopic cylinder 4-3 is installed at the bottom of the outer shell 1, and the output end of the telescopic cylinder 4-3 is connected with a cross frame 4-4. Both ends of the surface of the cross frame 4-4 are rotatably connected with fixing plates 4-5. An inclined roller 4-18 is rotatably connected between the fixing plate 4-5 and the connecting block 4-2. A driving motor 4-6 is installed on one side surface of the fixing plate 4-5, and the output end of the driving motor 4-6 is connected to and drives the rotation of the inclined roller 4-18. The inclined roller 4-18 cooperates with the incoming and outgoing conveying rollers 3 to convey the strip steel. A cavity pipeline 4-9 is fixed on one side of the fixing plate 4-5 and is provided with a connecting pipe 4-10. The connecting pipe 4-10 can be connected to a flushing device, and the flushing device can supply water through the flushing nozzles 4-11 to flush the strip steel. An air inlet pipeline 4-12 is also fixed and is connected with a blowing hood 4-13. A plurality of air ports 4-14 are arranged on both surfaces inside the blowing hood 4-13. The air inlet pipeline 4-12 can be connected to a high-pressure blowing device, and air is blown to the surface of the strip steel through the air ports 4-14 to dry the flushing liquid, so that the strip steel reaches a dry state. A collecting groove 4-15 is opened at the inner bottom of the outer shell 1, and a discharge pipeline 4-16 and a recycling box 4-17 are connected at the bottom, which can receive the water used for flushing and collect it.

[0031] Further, the upper surface height of the inlet and outlet conveying roller 3 is slightly lower than that of the inclined roller 4-18.

[0032] In this embodiment, due to the lower height position of the inlet and outlet conveying roller 3, when the strip steel moves, it can be conveyed by adhering to the surface of the inclined roller 4-18.

[0033] Further, the overall shape of the air blowing hood 4-13 is a U-shaped structure, and the bottom part of the air blowing hood 4-13 has a certain inclination angle.

[0034] In this embodiment, due to the U-shaped structure, the gas blown out inside the air blowing hood 4-13 can cover both the upper surface and the lower surface of the strip steel at the same time, and can be fully cleaned.

[0035] Further, the inner bottom of the outer shell 1 has a certain inclination angle, and the lowest part of the inner bottom surface of the outer shell 1 is concentrated at the collection tank 4-15.

[0036] In this embodiment, due to the inclined surface, the rinsing liquid can flow concentratedly into the collection tank 4-15.

[0037] Further, a pair of heating tubes 5 are installed inside the intake pipe 4-12.

[0038] In this embodiment, by installing the heating tubes 5 inside the intake pipe 4-12, the gas blown out through the intake pipe 4-12 can be heated, improving the drying effect on the rinsing liquid.

[0039] Further, the inclined roller 4-18 can be controlled by the telescopic cylinder 4-3 to descend to a horizontal angle.

[0040] In this embodiment, due to the liftable inclined angle effect, the inclined roller 4-18 can be restored to a horizontal angle state and can be adjusted according to strip steel of different thicknesses.

[0041] When surface treatment of the strip steel is required, the strip steel is conveyed by the inlet and outlet conveying roller 3. After being conveyed to the surface of the inclined roller 4-18, it will generate an inclined angle. The lower position abuts against the support roller 4-8, keeping the strip steel moving in a straight line. During the conveying process, the rinsing nozzle 4-11 is turned on to wash both surfaces of the strip steel. At the same time, air blowing is started, and the gas blown out from the air outlet 4-14 is heated by the heating tube 5 and then covers the surface of the strip steel, blowing off the liquid on the surface through the inclined angle and achieving sufficient drying. The treated strip steel can be discharged at the other end.

[0042] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
