Technical Field
[0001] This utility model relates to the field of galvanized steel strip processing technology, specifically to a device for cleaning and degreasing the surface of galvanized steel strip. Background Technology
[0002] Steel corrodes when it comes into contact with air and water during actual use. Therefore, galvanizing is usually performed on steel strips during the steel production process to prevent corrosion. This is how galvanized steel strips came to be. Steel strips are usually transported in coils. The galvanizing process involves several steps: uncoiling the coiled steel strip, conveying, galvanizing, cooling, and recoiling into galvanized steel coils. During the processing, galvanized steel strips are prone to leaving some grease residue on their surface, requiring cleaning with appropriate equipment to facilitate storage.
[0003] However, the adhesion between the upper and lower rollers of the cleaning device and the galvanized steel strip is not easy to adjust. It can usually only be adjusted when the machine is stopped, resulting in poor equipment efficiency. Moreover, the installation and disassembly are time-consuming and labor-intensive, which greatly reduces work efficiency.

[0013] The beneficial effects of this utility model are:
[0014] 1. This utility model utilizes a crank handle to rotate an active turntable. The active turntable, driven by a conveyor belt, rotates two driven turntables. These driven turntables, in turn, rotate two sets of bidirectional screws. These bidirectional screws, through threaded connections with corresponding slide blocks, slide the slide blocks outwards. The slide blocks then move one end of each set of hinge rods outwards, and the other end of each hinge rod moves a connecting plate upwards. This allows the connecting plates to bring the corresponding cleaning brushes closer together, facilitating adjustment of the contact force between the upper and lower cleaning brushes and the galvanized steel strip. This design effectively improves work efficiency.
[0015] 2. This utility model, by pressing two sets of pressing heads, causes two sets of connecting rods to slide downwards. Simultaneously, the two sets of pressing heads compress two sets of springs. As the connecting rods slide downwards, they also cause two sets of contact heads to move downwards. After the contact heads move downwards, the corresponding two sets of balls lose their contacting effect and are placed inside the placement slot. Then, the two sets of insertion cylinders are inserted into the two sets of insertion slots. By releasing the two sets of pressing heads, under the reaction force of the two sets of springs, the two sets of pressing heads can cause the two sets of connecting rods and contact heads to move upwards. The two sets of contact heads can push the corresponding two sets of balls outwards from the placement slot, thereby allowing the corresponding two sets of balls to engage with the insertion slot, thus completing the installation and fixing of the cleaning brush. The reverse operation facilitates the disassembly of the cleaning brush, and thus, through this design, work efficiency is further improved. Attached Figure Description

Through the above structure, the contact force between the upper and lower sets of cleaning brushes 18 and the galvanized steel strip can be easily adjusted, while the installation and disassembly of the cleaning brushes 18 are also facilitated, improving work efficiency.
[0028] The adjustment mechanism includes a crank handle 20. Two sets of sliding rods 11 are located near the top and bottom of the inner side of the cleaning pool 1. Two sets of sliding seats 12 are slidably connected to each set of sliding rods 11. Both sets of sliding seats 12 are threadedly connected to bidirectional screws 13 rotatably connected to the inner side of the cleaning pool 1. Hinges 15 are rotatably connected to both sides of each set of sliding seats 12. The other end of each set of hinges 15 is hinged to the bottom of a connecting plate 16. One end of each set of bidirectional screws 13 extends to the outside of the cleaning pool 1 and is connected to a driven turntable 14. A driving turntable 19 is rotatably connected to one side of the cleaning pool 1. The driving turntable 19 is connected to the two sets of driven turntables 14 via a conveyor belt 21. A crank handle 20 is installed on one side of the driving turntable 19. By cranking the crank handle 20... The active turntable 19 can be driven to rotate. Under the action of the conveyor belt 21, the active turntable 19 can drive the two driven turntables 14 to rotate. The two driven turntables 14 can drive the two sets of bidirectional screws 13 to rotate. The two sets of bidirectional screws 13, through the threaded connection with the corresponding two sets of slides 12, can drive the two sets of slides 12 to slide outward. The two sets of slides 12 can drive one end of the corresponding two sets of hinge rods 15 to move outward.

Thus, the two sets of connecting plates 16 can drive the corresponding two sets of cleaning brushes 18 to move closer to each other, so as to adjust the contact force between the upper and lower sets of cleaning brushes 18 and the galvanized steel strip. In this way, the work efficiency is effectively improved.
[0029] The connecting mechanism includes a plug-in cylinder 28 and a plug-in slot 32. A cleaning brush 18 is positioned on the top of a mounting plate 17.

By pressing the two sets of pressing heads 25, the two sets of pressing heads 25 can... The two sets of connecting rods 24 slide downwards, and at the same time, the two sets of pressing heads 25 can compress the two sets of springs 26. As the two sets of connecting rods 24 slide downwards, they can also drive the two sets of contact heads 27 to move downwards. After the two sets of contact heads 27 move downwards, the corresponding two sets of balls 30 can lose their contact effect and be placed inside the placement groove 29. Then, the two sets of plug-in tubes 28 are plugged into the two sets of plug-in grooves 32. Then, by releasing the two sets of pressing heads 25, the two sets of pressing heads 25 can drive the two sets of connecting rods 24 and contact heads 27 to move upwards under the action of the reaction force of the two sets of springs 26. The two sets of contact heads 27 can squeeze the corresponding two sets of balls 30 outwards from the placement groove 29, so that the corresponding two sets of balls 30 can abut and engage with the plug-in groove 32, thereby completing the installation and fixing of the cleaning brush 18. The cleaning brush 18 can be easily disassembled by reversing the operation, and thus the work efficiency is further improved by setting it up.

The torsion spring 36 allows one end of each set of scrapers 35 to adaptively fit against the surface of the strip steel through which it passes, so that the residual solution on the surface of the strip steel can be easily scraped off during the strip steel winding process.
[0031] The drying mechanism includes a hot air box 39. A fixed frame 37 is provided on the top of the extension plate 2 on one side of the upright frame 33.

An air supply pipe 40 is provided on one side of the hot air box 39. One end of each set of exhaust pipes 38 extends to the outside of the fixed frame 37 and is connected to the air supply pipe 40. Through the hot air box 39 and the air supply pipe 40, hot air can be discharged through the two sets of exhaust pipes 38, so that the surface of the strip can be dried during the strip coiling process.
[0032] The locking component includes a fixing seat 5, which is sleeved on the outer ring of the rotating shaft 4. The fixing seat 5 is threadedly connected to a locking screw 6. The fixing seat 5 allows for easy installation and disassembly of the steel coil, and the locking screw 6 allows for easy fixation of the fixing seat 5 and the steel coil. A discharge pipe 41 is provided on one side of the cleaning pool 1 near the bottom. The discharge pipe 41 allows for easy discharge of the cleaning solution after cleaning.
[0033] Working principle: First, by pressing the two sets of pressing heads 25, the two sets of pressing heads 25 can drive the two sets of connecting rods 24 to slide downward. At the same time, the two sets of pressing heads 25 can compress the two sets of springs 26. As the two sets of connecting rods 24 slide downward, they can drive the two sets of abutment heads 27 to move downward. After the two sets of abutment heads 27 move downward, the corresponding two sets of balls 30 can lose their abutment effect and be placed inside the placement groove 29. Then, the two sets of plug-in tubes 28 are plugged into the two sets of plug-in grooves 32. Then, by releasing the two sets of pressing heads 25, the two sets of pressing heads 25 can drive the two sets of connecting rods 24 and abutment heads 27 to move upward under the action of the reaction force of the two sets of springs 26. The two sets of abutment heads 27 can squeeze the corresponding two sets of balls 30 outward to the outside of the placement groove 29, so that the corresponding two sets of balls 30 can abut and engage with the plug-in groove 32, thereby completing the installation and fixing of the cleaning brush 18.
[0034] Then, by cranking the crank handle 20, the crank handle 20 can drive the drive turntable 19 to rotate. The drive turntable 19, under the action of the conveyor belt 21, can drive the two sets of driven turntables 14 to rotate. The two sets of driven turntables 14 can drive the two sets of bidirectional screws 13 to rotate. The two sets of bidirectional screws 13, through their threaded connection with the corresponding two sets of slide blocks 12, can drive the two sets of slide blocks 12 to slide outwards. The two sets of slide blocks 12 can drive one end of the corresponding two sets of hinge rods 15 to move outwards. The other end of the corresponding two sets of hinge rods 15 can, as the slide blocks 12 move, drive the connecting plate 16 to move upwards, thereby... The two sets of connecting plates 16 can drive the corresponding two sets of cleaning brushes 18 to move closer to each other, so as to adjust the contact force between the upper and lower sets of cleaning brushes 18 and the galvanized strip steel, which facilitates the cleaning of oil stains on the surface of the strip steel. The torsion spring 36 can make one end of the two sets of scrapers 35 adaptively contact the surface of the strip steel through which they pass, so that the residual solution on the surface of the strip steel can be easily scraped off during the strip steel winding process. The hot air box 39 and the air supply pipe 40 can discharge hot air through the two sets of exhaust pipes 38, so as to dry the surface of the strip steel, thereby completing the entire operation process.
