Description

Technical Field

[0001] The utility model relates to the technical field of steel strip surface treatment, in particular to a passivation treatment device for the surface of hot-dip galvanized steel strips. Background Technique

[0002] Galvanized strip steel is a long and narrow strip steel plate that is cold-rolled or hot-rolled and coated with a layer of raw materials called zinc and aluminum to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The matrix of hot-dip galvanized strip steel undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant and tightly structured zinc-iron alloy layer. The alloy layer, pure zinc layer, and strip steel matrix are integrated, so it has strong corrosion resistance.

[0003] In the prior art, the usual passivation treatment device for the surface of hot-dip galvanized steel strips does not have a component that can well adjust the direction and angle of the air knife. If the air knife cannot be well adjusted in angle, it will have an adverse impact on the production quality of hot-dip galvanized strip steel. Since the direction and strength of the airflow sprayed by the air knife are affected, the coating thickness at the middle and edge parts of the strip steel will be inconsistent. Usually, the middle part is thinner and the two sides are thicker, which will lead to a decline in the quality of the finished product, affect its competitiveness in the market, and may also cause defects such as zinc grains and streaks on the surface of the zinc layer. These defects not only reduce the surface quality of the galvanized sheet but may also affect its subsequent processing and use performance. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution for a surface passivation treatment device for hot-dip galvanized steel strips:

[0026] In the embodiments of the present invention, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, a support arm 2 is installed on one side of the outer wall of the cabinet body 1, and an adjustment component 3 is installed on one side of the top end of the support arm 2. The adjustment component 3 includes a motor 301 fixedly connected to the support arm 2. A first rotating shaft 302 is installed in the middle of the motor 301. One end of the first rotating shaft 302 extends from the bottom end of the motor 301. The bottom end of the first rotating shaft 302 is rotatably connected to a rotating block 303. A connecting rod 304 is installed on one side of the outer wall of the rotating block 303. One end of the connecting rod 304 is fixedly connected to a fixing block 305. A telescopic rod 306 is installed inside the fixing block 305. The bottom end of the telescopic rod 306 is installed with a first mounting block 307. A first spherical joint 308 is installed in the middle of the bottom end of the first mounting block 307. A pipeline 309 is installed on the outer wall of the first spherical joint 308. A second spherical joint 310 is installed in the middle of the pipeline 309. An air knife 311 is installed at one end of the pipeline 309 away from the first spherical joint 308. A rectangular fixing ring is installed on the outer wall of the second spherical joint 310. A support column 312 is fixedly connected to one side of the rectangular fixing ring. A control panel 6 is installed on one side of the outer wall of the cabinet body 1. A plurality of control buttons are installed on the surface of the control panel 6. The control buttons are electrically connected to the motor 301. An activity port 7 is opened on one side of the top end of the cabinet body 1. The activity port 7 is circular. The diameter of the activity port 7 is adapted to the activity range of the pipeline 309.

[0027] It should be noted that: the motor 301 is electrically connected to the control panel 6, ensuring that the motor 301 can make corresponding responses when the staff operates the control panel 6. At the same time, an air pump is arranged inside the telescopic rod 306, and the air pump is electrically connected to the control panel 6. When the air pump inside the telescopic rod 306 is started by pressing the control panel 6, it exhausts air outward. Thus, the air flow circulates through the air channels opened inside the first spherical joint 308, the pipeline 309, and the second spherical joint 310, and is ejected from the air ports opened at the bottom end of the air knife 311. And when the motor 301 is started, it drives the first rotating shaft 302 to start rotating. The first rotating shaft 302 is fixedly connected to the rotating block 303, and the rotating block 303 will drive the fixing block 305 to start rotating through the connecting rod 304. The telescopic rod 306 is fixedly connected to the first mounting block 307. Therefore, when the fixing block 305 drives the telescopic rod 306 to rotate around the first rotating shaft 302 as the center, it drives the first mounting block 307. The telescopic rod 306 will move horizontally on the fixing block 305 to provide a certain activity space for the adjustment component 3 to prevent jamming. The first spherical joint 308 and the second spherical joint 310 can rotate within a spherical link, and the 360-degree angle adjustment of the air knife 311 can be achieved, achieving the effect of controlling the air flow outlet angle to avoid defects such as over-galvanizing at the edges.

[0028] Refer to Figure 3, a detection component 4 is installed on one side of the top end of the cabinet body 1. The detection component 4 includes a fixed rod 401 installed on one side of the top end of the cabinet body 1. A slide rail 402 is opened at the top end of the fixed rod 401. A bidirectional lead screw 403 is installed on the inner wall of the slide rail 402. The bidirectional lead screw 403 is rotationally connected to a sliding block 404. A probe 405 is installed at the bottom end of the sliding block 404.

[0029] It should be noted that: by rotating the bidirectional lead screw 403, the two sliding blocks 404 start to move towards the opposite sides, driving the probe 405 to adjust the detection width according to the requirements of different working surfaces.

[0030] Refer to Figure 4 , a transmission component 5 is arranged on the cabinet body 1. The transmission component 5 includes two second mounting blocks 501 fixedly connected to the outer wall of the cabinet body 1. A first transmission shaft 502 is installed on the opposite sides of the two second mounting blocks 501. A first roller 503 is sleeved on the outer wall of the first transmission shaft 502. A first transmission wheel 504 is installed at one end of the first transmission shaft 502. A transmission belt 505 is rotationally connected to the outer wall of the first transmission wheel 504. The first transmission wheel 504 is connected to a second transmission wheel 506 through the transmission belt 505. A second transmission shaft 507 is installed in the middle of the second transmission wheel 506. A second roller 508 is sleeved on the outer wall of the second transmission shaft 507. Second rotating shafts 509 are installed at the bottoms of the first roller 503 and the second roller 508. A third roller 510 is sleeved on the outside of the two second rotating shafts 509.

[0031] It should be noted that: through the first transmission wheel 504, the transmission belt 505, and the second transmission wheel 506, the speed of the transmission steel belt of the equipment can be ensured to be consistent, ensuring that the material is uniformly processed during the processing, thereby avoiding the phenomenon of uneven performance caused by speed fluctuations.

[0032] Working principle: The motor 301 is electrically connected to the control panel 6, ensuring that the motor 301 can respond accordingly when the operator manipulates the control panel 6. At the same time, an air pump is provided inside the telescopic rod 306, and the air pump is electrically connected to the control panel 6. When the air pump inside the telescopic rod 306 is started by pressing the control panel 6, it exhausts air outward. Thus, the air flow circulates through the air channels opened inside the first spherical joint 308, the pipeline 309, and the second spherical joint 310, and is ejected from the air ports opened at the bottom of the air knife 311. And when the motor 301 is started, it drives the first rotating shaft 302 to start rotating. The first rotating shaft 302 is fixedly connected to the rotating block 303, and the rotating block 303 will drive the fixed block 305 to start rotating through the connecting rod 304. The telescopic rod 306 is fixedly connected to the first mounting block 307. Therefore, when the fixed block 305 drives the telescopic rod 306 to rotate around the first rotating shaft 302 as the center, it drives the first mounting block 307. The telescopic rod 306 will move horizontally on the fixed block 305 to provide a certain movement space for the adjusting component 3 to prevent jamming. The first spherical joint 308 and the second spherical joint 310 can rotate within a spherical joint, achieving a 360-degree angle adjustment of the air knife 311, and achieving the effect of controlling the air flow outlet angle to avoid defects such as over-galvanizing at the edges.
