Description

Technical Field

[0001] This utility model relates to the technical field of steel coil processing, and in particular to a passivation treatment device for galvanized steel coils. Background Technology

[0002] As is well known, in order to improve the corrosion resistance of galvanized steel coils, a passivation film is often coated on the surface of the galvanized steel coils using a passivation solution to isolate the galvanized steel coils from the corrosive media, thereby improving the durability of the galvanized steel coils.

[0003] Existing passivation treatment devices for galvanized steel coils, such as the passivation film roller coating machine for galvanized steel coils disclosed in utility model patent application number 202323015769.4, mainly include a frame and two passivation liquid storage tanks fixedly installed on the frame. A galvanized steel coil strip is driven between the two passivation liquid storage tanks. An unwinding drum for unwinding the galvanized steel coil strip is rotatably installed on the bottom side of the frame via a mounting plate. In use, the drive motors on both sides drive the liquid-taking roller to rotate. The liquid-taking roller takes the passivation liquid stored in the passivation liquid storage tank while rotating. After taking the liquid, the liquid-taking roller is also rolled and conveyed with the coating roller, thereby transferring the passivation liquid on the liquid-taking roller to the coating roller. Subsequently, the coating roller, while rotating, rolls the passivation liquid onto the galvanized steel coil strip.

[0004] However, most existing steel coil passivation treatment devices only use coating rollers to coat the steel coils, which makes it difficult to guarantee the coating effect. This can easily lead to substandard passivation film thickness in some areas, and the residual liquid on the surface of the steel coils is difficult to remove completely, affecting the subsequent drying effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a passivation treatment device for galvanized steel coils that not only enhances the coating effect of passivation liquid by spraying and smearing to ensure that the passivation film thickness meets the standard, but also scrapes off the residual passivation liquid after coating and dries the surface of the steel coil, thereby improving work efficiency.

[0006] This utility model discloses a passivation treatment device for galvanized steel coils, including a conveying mechanism; it also includes a liquid storage mechanism, a driving mechanism, a spraying mechanism, and a treatment mechanism. The liquid storage mechanism is installed on the conveying mechanism and stirs the passivation liquid. The driving mechanism is installed on the liquid storage mechanism and drives the stirring shaft to rotate. The spraying mechanism is installed on the driving mechanism and conveys and sprays the passivation liquid. The treatment mechanism is installed on the conveying mechanism and applies and dries the passivation liquid. The operator stores the passivation liquid in the liquid storage mechanism, the driving mechanism drives the stirring shaft to stir the passivation liquid to prevent sedimentation, the spraying mechanism is activated to spray the passivation liquid in the liquid storage mechanism onto the surface of the steel coil, and then the treatment mechanism applies and dries the passivation liquid on the surface of the steel coil to facilitate subsequent winding.

The bottom end of the worktable is connected to the ground. The unwinding roller is mounted on the worktable. Both sets of positioning rollers are mounted on the worktable. Both sets of guide rollers are rotatably mounted on the worktable. The winding roller is mounted on the worktable. The steel coil on the unwinding roller is released, and the steel strip passes through the two sets of positioning rollers, passes around the two sets of guide rollers, and is wound onto the winding roller. The positioning rollers facilitate clamping of the steel strip and prevent the steel coil from deviating.

The liquid storage tank is mounted on a workbench, the stirring shaft is rotatably mounted on the liquid storage tank, the multiple sets of stirring rods are all mounted on the stirring shaft, and the first pulley is mounted on the stirring shaft. The passivation liquid is stored in the liquid storage tank. The drive mechanism drives the first pulley to rotate, and the first pulley drives the stirring shaft and the multiple sets of stirring rods to rotate. The multiple sets of stirring rods stir the passivation liquid to prevent the passivation liquid from settling.

[0009] Preferably, the drive mechanism includes a motor, a dual-output-shaft reducer, a first drive shaft, a second pulley, and a belt. The motor is mounted on the workbench, and its output end is connected to the input end of the dual-output-shaft reducer. The output end of the dual-output-shaft reducer is connected to the input end of the first drive shaft. The second pulley is mounted on the first drive shaft, and the belt is tensioned between the first pulley and the second pulley. When the motor is started, it drives the first drive shaft to rotate via the dual-output-shaft reducer. The first drive shaft drives the second pulley to rotate, and the second pulley drives the first pulley to rotate via the belt.

The delivery pump extracts the passivation liquid from the storage tank through the liquid extraction pipe and delivers the passivation liquid to the multiple sets of nozzles through the liquid delivery pipe. The multiple sets of nozzles spray the passivation liquid onto the surface of the steel strip.

[0011] Preferably, the processing mechanism includes two sets of coating rollers, two sets of gears, two sets of hot air blowers, and two sets of scrapers.
