[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a hot-dip galvanized steel strip continuous cleaning equipment, including an installation wall 1 and a steel strip 2, and also including a winder and an unwinder, the winder is arranged on the left side of the installation wall 1, the unwinder is arranged on the right side of the installation wall 1, and a pickling tank 4 is arranged at the front end of the installation wall 1, a transfer roller 3 is installed on the installation wall 1, and a pickling tank 4 is also arranged on the installation wall 1, there are two transfer rollers 3, which are respectively located at the upper end of the right side of the pickling tank 4 and in the inner wall of the pickling tank 4, and the steel strip 2 passes over the transfer roller 3.

[0023] It also includes a cleaning assembly of the mounting wall 1, which includes a cleaning roller 5. The steel belt 2 collides with the cleaning roller 5 after passing through the pickling tank 4. There are two groups of cleaning rollers 5 symmetrically arranged on both sides of the steel belt 2. There are ten cleaning rollers 5 divided into two groups, which are symmetrically arranged on both sides of the steel belt 2 in a linear array with equal spacing. A limiting block 7 is slidably connected in the mounting wall 1, and a mounting plate 6 is fixedly connected to the limiting block 7. The cleaning roller 5 is rotatably connected to the mounting plate 6. A cleaning groove is opened on the cleaning roller 5, and the cleaning groove is opened on the side of the cleaning roller 5 in a circular array with equal spacing.

[0024] By adopting the above design, after the steel strip 2 is immersed and cleaned in the pickling tank 4, although acid and residue may remain on its surface, the acid and residue will be scraped off from its surface by the cleaning rollers 5 that are in contact with the steel strip 2 when the steel strip 2 passes between the two groups of cleaning rollers 5. In this way, after the steel strip 2 is immersed and cleaned, the surface impurities of the steel strip 2 are scraped off again, which can more thoroughly remove the acid and residue on the surface of the steel strip 2 and avoid damaging the surface of the steel strip 2.

[0025] Further, refer to Figure 1 and Figure 3 A limiting groove 8 is provided in the installation wall 1, and a limiting block 7 passes through the limiting groove 8 and is arranged on the back of the installation wall 1. An adjustment component is also provided on the back of the installation wall 1, and the adjustment component includes a mounting platform 9. The mounting platform 9 has two symmetrical upper and lower portions of the limiting groove 8. A motor 11 is installed on the top surface of the mounting platform 9. A bidirectional screw rod 10 threadedly connected to the limiting block 7 is rotatably connected in the mounting platform 9, and the bidirectional screw rod 10 is fixedly connected to the output shaft of the motor 11.

[0026] When it is necessary to adjust the spacing between the cleaning rollers 5, the bidirectional screw 10 can be driven to rotate by starting the motor 11, so that the two limit blocks 7 threadedly connected to the bidirectional screw 10 and limited by the limit groove 8 move toward or away from each other, and then the distance between the cleaning rollers 5 and the steel belt 2 on both sides can be adjusted in a mirror-image manner with the steel belt 2 as the axis.

[0027] By adopting the above design, the distance between the two groups of cleaning rollers 5 can be adjusted, so that the cleaning rollers 5 can be suitable for surface cleaning operations of steel strips 2 of different thicknesses, thereby further improving the practicability of the device.

[0028] refer to Figure 1 and Figure 4 Furthermore, a cleaning component is provided between the cleaning component and the winding machine, and the cleaning component includes a spray component 12 fixedly connected to the mounting wall 1, and eight spray components 12 are symmetrically arranged in two groups on the upper and lower sides of the winding path of the steel strip 2, and a mounting rod 13 is provided behind each spray component 12, and a flexible scraper 14 is provided in the mounting rod 13.

[0029] After the cleaning assembly completes cleaning of the steel strip 2, the cleaning assembly starts to work as the steel strip 2 continues to move toward the winder.

[0030] Specifically, the spraying member 12 sprays the steel strip 2 , which helps to further remove the acid or other residues that may remain on the surface of the steel strip 2 .

[0031] A flexible scraper 14 is installed on the mounting rod 13 arranged behind each spraying member 12. The flexible scraper 14 will gently but effectively scrape the surface of the steel strip 2 to ensure that the surface of the steel strip 2 is as clean as possible without residue before entering the winder.

[0032] Through the dual effects of spraying and scraping, the residues on the surface of the steel strip 2 can be removed more thoroughly, ensuring the cleanliness of the steel strip 2 before entering the winder.

[0033] The design of the flexible scraper 14 can avoid scratching or damaging the surface of the steel strip 2, ensuring that the quality of the steel strip 2 is not affected.

[0034] Due to the improved cleaning effect, the surface condition of the steel strip 2 is better when entering the next process (such as galvanizing), which is beneficial to improving the quality and stability of the final product.

[0035] In addition, a water collection tank 15 is provided at the lower end of the installation wall 1 and below the cleaning and washing components.

[0036] The water collecting tank 15 is provided to collect waste water and waste liquid, which provides convenience for subsequent waste water treatment, helps to reduce the pollution of waste water discharge to the environment, and better meets the requirements of modern industry for environmental protection.

[0037] Working principle:

[0038] When in use, the unwinder unwinds and the reeler reels, driving the steel strip 2 to pass over the transfer roller 3. During this process, the steel strip 2 will enter the pickling tank 4 for immersion and cleaning. After the immersion is completed.

[0039] The steel strip 2 will pass through the cleaning and washing components in turn. When passing through the cleaning component, the acid and residue on its surface will be scraped off by the cleaning roller 5. When passing through the washing component, the spray part 12 will spray the steel strip 2, which will help to further remove the acid or other residue that may remain on the surface of the steel strip 2. The flexible scraper 14 will gently but effectively scrape the surface of the steel strip 2 to ensure that the surface of the steel strip 2 is as clean as possible without residue before entering the winder.
