[0002] Cold-rolled steel sheet is a product made by rolling hot-rolled coils at room temperature below the recrystallization temperature. It is widely used in automobile manufacturing, electrical products, etc. Pickling of cold-rolled steel sheet is an indispensable step in steel processing. Its main purpose is to remove iron oxide scale, rust and contaminants from the surface of the steel sheet to improve the surface smoothness and corrosion resistance.

[0003] When pickling cold-rolled steel sheets, they need to be placed in a cleaning machine. Under the action of hydrochloric acid solution, the iron oxide scale is dissolved through a chemical reaction. However, during the use of existing hydrochloric acid cleaning machines, impurities attached to the surface of the cold-rolled steel sheets during production will remain in the cleaning machine. As a result, when cleaning the residue in the cleaning machine, the height of the cleaning tank makes it difficult for workers to enter and exit the tank, and the cleaning and transportation of impurities is time-consuming and labor-intensive, affecting the efficiency of the operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A hydrochloric acid cleaning machine for pickling cold-rolled steel sheets includes a cleaning tank 1. A connecting plate 2, a tank cover 3, and a drive assembly 4 are mounted on the outer surface of the cleaning tank 1. An outer frame 5 is rotatably connected to the inner surface of the cleaning tank 1. A cover plate 6 is bolted to the surface of the outer frame 5. An inner frame 7 is mounted on the inner surface of the outer frame 5. A partition 8 is fixedly connected to the inner surface of the inner frame 7. A cold-rolled steel sheet 9 is inserted into the surface of the partition 8. A fixing block 10, a mounting plate 14, and a mounting frame 20 are fixedly connected to the surface of the cleaning tank 1. A movable block 11 and a side plate 15 are fixedly connected to the surface of the connecting plate 2. A rotating hole 12 is formed on the surface of the fixing block 10. A rotating block 13 is fixedly connected to the surface of the movable block 11. A mounting hole 16 is formed on the surface of the mounting plate 14. A sliding groove 17 is formed on the surface of the side plate 15. A support rod 18 is movably connected to the surface of the cleaning tank 1. A movable block 19 is fixedly connected to the surface of the support rod 18. The surface of the 20 is provided with a slot 21. The surface of the mounting frame 20 is fixedly connected with a screw 22. The surface of the screw 22 is equipped with a nut 23. When cleaning the cold-rolled plate, multiple sets of cold-rolled plate bodies 9 are first inserted into the inner frame 7 between two adjacent partitions 8 and then placed together into the outer frame 5 after alignment. The cover plate 6 is then fixed to the surface of the inner frame 7 with bolts to achieve the effect of placing the cold-rolled plate body 9 inside the cleaning machine. After that, hydrochloric acid solution is added to the cleaning tank 1 and the drive assembly 4 is started to drive the outer frame 5 to rotate. The surface of the cold-rolled plate body 9 and the hydrochloric acid solution react chemically to achieve the effect of pickling. The drive assembly 4 is an existing structure and consists of a motor, a pinion gear and a large gear. The motor is fixed to the outer surface of the cleaning tank 1 and connected to the pinion gear to drive its rotation. The pinion gear and the large gear are engaged. The rotating shaft fixed on the large gear is fixed to the outside of the outer frame 5.

[0025] Furthermore, there are two sets of fixed blocks 10 and movable blocks 11. The two sets of fixed blocks 10 are installed on both sides of the cleaning tank 1, and the two sets of movable blocks 11 are installed on both sides of the connecting plate 2. The movable blocks 11 are movably connected to the surface of the fixed blocks 10. The diameter of the rotating hole 12 is the same as the diameter of the rotating block 13. The rotating block 13 is rotatably connected to the surface of the rotating hole 12. With the connection of the rotating hole 12 and the rotating block 13, the connection effect of the fixed blocks 10 and the movable blocks 11 can be achieved, thereby enabling the connecting plate 2 to rotate around the rotating block 13.

[0026] Furthermore, there are two sets of mounting plates 14 and side plates 15. The two sets of mounting plates 14 are installed on both sides of the cleaning tank 1, and the two sets of side plates 15 are installed on both sides of the connecting plate 2. The diameter of the mounting hole 16 is the same as the inner diameter of the moving block 19. The surface of the slide groove 17 is "L" shaped. The support rod 18 can be installed through the mounting plates 14 and side plates 15, and the moving block 19 can be installed through the mounting hole 16 and slide groove 17. The width of the slide groove 17 is the same as the inner diameter of the moving block 19.

[0027] Furthermore, one end of the support rod 18 is attached to the surface of the mounting plate 14, and the other end of the support rod 18 is attached to the surface of the side plate 15. The moving block 19 has a "T" shaped cross section, and two sets of moving blocks 19 are provided. The two sets of moving blocks 19 are installed at both ends of the support rod 18. Under the action of the support rod 18, the mounting plate 14 and the side plate 15 can be connected, thereby realizing the connection between the cleaning tank 1 and the connecting plate 2. Under the action of the moving block 19, both ends of the support rod 18 can be movably limited to the surfaces of the mounting plate 14 and the side plate 15, respectively.

[0028] Furthermore, one set of movable blocks 19 is rotatably connected to the surface of the mounting hole 16, and another set of movable blocks 19 is movably connected to the surface of the slide groove 17. The outer diameter of the movable blocks 19 is larger than the diameter of the mounting hole 16. With the connection between the movable blocks 19 and the mounting hole 16, the support rod 18 can rotate around the set of movable blocks 19. With the engagement between the movable blocks 19 and the slide groove 17 at the end away from the movable block 11, the support rod 18 can support the connecting plate 2.

[0029] Furthermore, the surface of the mounting frame 20 is U-shaped, and the inner surface dimension of the mounting frame 20 is larger than the surface dimension of the connecting plate 2. The connecting plate 2 can be installed through the mounting frame 20, so that the connecting plate 2 abuts against the surface of the mounting frame 20 when it is in the closed state.

[0030] Furthermore, the slot 21 engages with the surface of the screw 22. One end of the screw 22 is fixedly connected to the surface of the mounting frame 20, and the other end of the screw 22 is threadedly connected to the inner surface of the nut 23. The nut 23 abuts against the surface of the connecting plate 2. The slot 21 and the screw 22 are linearly arrayed on the surfaces of the connecting plate 2 and the screw 22, respectively. The slot 21 ensures that the connecting plate 2 is not obstructed by the screw 22 when connected to the mounting frame 20, and the screw 22 passes through the surface of the connecting plate 2 through the slot 21. With the connection of the screw 22, the slot 21, and the nut 23, the rotation of the connecting plate 2 can be limited.

[0031] Working principle: When the hydrochloric acid cleaning machine finishes pickling the cold-rolled plate 9 and cleans the inside, first rotate the nut 23 so that it moves on the surface of the screw 22 through the thread and cancels the engagement with the connecting plate 2. Then push the connecting plate 2 out from the inside of the cleaning tank 1 to separate it from the mounting frame 20. The screw 22 then cancels the engagement with the slot 21, so that the connecting plate 2 rotates outward from the cleaning tank 1 around the rotating block 13. The rotating block 13 rotates on the surface of the rotating hole 12 and drives the support rod 18 to rotate around the moving block 19 on the mounting plate 14. This set of moving blocks 19 rotates on the surface of the mounting hole 16. At the same time, another set of moving blocks 19 slides along the surface of the slide groove 17 and engages at the end away from the moving block 11, so that the connecting plate 2 is in an open state and is supported. At this time, the worker can enter the cleaning tank 1 from the open part of the connecting plate 2 to clean the residue.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
