DETAILED DESCRIPTION

[0020] 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.

[0021] Example: Figure 1-4 As shown, the utility model provides a pickling device for wear-resistant cold-rolled steel strip for spring pads, including a cold-rolled steel strip body 6, and a heat insulation layer 61 is provided on the surface of the cold-rolled steel strip body 6. The heat insulation layer 61 specifically adopts ceramic fiber material. The ceramic fiber material adopted in the heat insulation layer 61 has a high high temperature resistance effect, and the cold-rolled steel strip body 6 is heat-protected. A protective layer 62 is provided on the side of the heat insulation layer 61 away from the cold-rolled steel strip body 6 through an adhesive. The specific materials of the protective layer 62 are cast nylon and silicon carbide. The cast nylon and silicon carbide used in the protective layer 62 have a high hardness, thereby increasing the wear resistance of the surface of the cold-rolled steel strip body 6.

[0022] A pickling device for wear-resistant cold-rolled strip steel with spring pads comprises a processing box 1, wherein both ends of the outer wall of the processing box 1 are penetrated with through holes 11, and two symmetrically distributed bottom plates 12 are fixedly arranged on the inner wall of the processing box 1 near one of the through holes 11, and the two bottom plates 12 are respectively located above and below the through holes 11, and a rotating rod 13 is rotatably arranged at the middle end of the bottom plate 12, and a brush plate 14 is fixedly arranged at one end of the rotating rod 13 near the through hole 11, and a connecting component is arranged between the two rotating rods 13, and a cross plate 2 is fixedly installed near the bottom plate 12 at the upper part of the processing box 1, and a U-shaped bracket 21 is fixedly arranged on the lower surface of the cross plate 2, and a first vacuum cleaner 22 is installed on both sides of the bracket 21, and a second vacuum cleaner 23 is arranged at the bottom of the processing box 1 directly below the bracket 21, and a vibration component is arranged on the bracket 21, and a pickling box 5 is arranged at one end of the outer wall of the processing box 1 away from the bottom plate 12, and a pickling spray head is arranged in the pickling box 5 to perform pickling operation on the cleaned cold-rolled strip steel.

[0023] The vibration assembly includes a rotating shaft 24, both ends of which rotate and penetrate the bracket 21. The rotating shaft 24 is located in the bracket 21 and is fixed with a circular top plate 25. The rotating shaft 24 is fixed at the eccentric position of the top plate 25. Both ends of the bracket 21 slide up and down together with a movable plate 26. The lower surface of the movable plate 26 is fixed with a vertically arranged top rod 27. The bottom of the top rod 27 penetrates the bracket 21. A reset spring 28 is provided on the top rod 27 between the movable plate 26 and the bottom surface of the bracket 21.

[0024] By adopting the above technical solution, when the rotating shaft 24 drives the eccentrically arranged top plate 25 to rotate, the top plate 25 cooperates with the return spring 28 to make the cold-rolled strip vibrate, so that impurities that are not easy to adhere to after being cleaned by the brush plate 14 are vibrated away from the cold-rolled strip, making it convenient for the subsequent first vacuum cleaner 22 and the second vacuum cleaner 23 to clean the dust and impurities.

[0025] The connecting assembly includes a connecting rod 15, and the connecting rod 15 is arranged in two numbers, corresponding to one end of the two rotating rods 13 away from the bottom plate 12 respectively. The rotating rod 13 and the connecting rod 15 are connected by two meshing bevel gears 16. The ends of the two connecting rods 15 away from the rotating rods 13 pass through the processing box 1 and are jointly driven by a first belt 17.

[0026] By adopting the above technical solution, the connection rod 15, the bevel gear 16 and the first belt 17 are arranged so that the two rotating rods 13 can simultaneously drive the brush plate 14 to rotate, thereby cleaning impurities attached to the surface of the cold-rolled strip and increasing the linkage of the device.

[0027] One end of the rotating shaft 24 close to the connecting rod 15 passes through the processing box 1, and a second belt 18 is provided on a common transmission sleeve between the rotating shaft 24 and one of the connecting rods 15.

[0028] By adopting the above technical solution, the second belt 18 can make the rotating rod 13 and the rotating shaft 24 rotate at the same time, thereby increasing the linkage of the device. At the same time, the connection between the first belt 17 and the second belt 18 in the text is driven by a pulley, which is specifically drawn in the figure, so no further details are given.

[0029] A motor 29 is disposed on the outer wall of the processing box 1 near the rotating shaft 24 , and an output end of the motor 29 is coaxially fixedly disposed on the rotating shaft 24 .

[0030] By adopting the above technical solution, the motor 29 is provided to provide power for the rotation of the rotating rod 13 and the rotating shaft 24, and at the same time it is convenient for the staff to operate.

[0031] Two symmetrically distributed transmission rollers 4 are installed on the outer wall of the processing box 1 near the opening 11.

[0032] By adopting the above technical solution, the driving roller 4 can be connected through two meshing gears so as to rotate towards each other, thereby limiting the position of the cold-rolled steel strip and providing a certain amount of power to move the cold-rolled steel strip.

[0033] Working principle: In actual use, the motor 29 is started, and the motor 29 can directly drive the rotating shaft 24 to rotate. The rotating shaft 24 can drive one of the connecting rods 15 to rotate through the second belt 18. At this time, the two rotating rods 13 can be driven to rotate at the same time through the connecting rod 15, the bevel gear 16 and the first belt 17 in the connecting assembly. At this time, the rotating rod 13 will drive the brush plate 14 to rotate. The brush plate 14 will clean the impurities attached to the surface of the cold-rolled strip and detach them from the cold-rolled strip or loosen them and no longer stick to the cold-rolled strip. Then the cold-rolled strip will move to the positions of the first vacuum cleaner 22 and the second vacuum cleaner 23. When the motor 29 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the eccentrically arranged top plate 25 to rotate. When the side wall of the top plate 25 contacts the movable plate 26, the movable plate 26 will be forced to move downward, thereby the top rod 27 fixed at the bottom of the movable plate 26 The top plate 25 is moved downward to make contact with the cold-rolled strip to push the cold-rolled strip. At the same time, as the top plate 25 continues to rotate, the top plate 25 will no longer squeeze the movable plate 26. At this time, the movable plate 26 will move upward under the push of the reset spring 28, driving the push rod 27 to separate from the cold-rolled strip. As the top plate 25 squeezes the movable plate 26 again, the push rod 27 pushes the cold-rolled strip again. This is repeated, which can make the cold-rolled strip vibrate, so that impurities that are not easy to adhere to after being cleaned by the brush plate 14 are vibrated and separated from the cold-rolled strip. At this time, the first vacuum cleaner 22 and the second vacuum cleaner 23 can directly absorb and store the detached dust and impurities to avoid adhering to the cold-rolled strip before pickling. Through the above operation, the impurities attached to the surface of the cold-rolled strip can be cleaned before pickling, thereby ensuring that the acid used for pickling reduces the accumulation of impurities during subsequent recycling, thereby ensuring the effect of pickling.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
