Description

Technical Field

[0001] The utility model relates to the technical field of pickling and leveling machines, in particular to a leveling structure for pickling and leveling machines. Background Art

[0002] The flattening machine is especially suitable for the strip flattening machine and cold rolling skin pass machine. After recrystallization annealing and galvanizing, the strip often needs to be flattened so that the strip can obtain the necessary performance and surface quality to meet the requirements of the subsequent processing. In the flattening machine on the continuous hot-dip galvanizing unit, flattening is essentially a rolling deformation with a small reduction.

[0003] Pickling plate is a metal plate treated by pickling process, which is usually used to remove oxides, rust, oil and other impurities on the surface of steel plates. After use and transportation, the pickling plate will bend to a certain extent. In order not to affect the subsequent use, it will be placed in a flattening machine for flattening. However, the existing flattening machine has the following problems during use:

[0004] First, the leveling machine mainly relies on the rotation of the upper and lower rollers to correct the pickling plate. Long-term use will cause wear, but the space between the rollers is small, making it difficult to maintain and clean the rollers.

[0005] In addition, the plates need to be manually supported when feeding, and the plates are relatively thin and can easily scratch the skin, which poses a certain risk. In addition, if the leveled plates can only be fed out by hand, it is difficult to maintain the flatness of the plates, and the plates are still prone to bending under the influence of gravity. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a leveling structure for a pickling and leveling machine, which overcomes the deficiencies in the prior art and effectively solves the problems that the roller body is not easy to clean, feeding is risky and the material is easy to bend during discharge.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A leveling structure for a pickling and leveling machine, comprising a frame, a symmetrically distributed chain conveying box is installed on the top outer wall of the frame, and bottom pressure rollers distributed at equal distances are connected between two chain conveying boxes, a first gear is installed on the outer wall of one end of the bottom pressure roller, a top frame is hingedly connected to the outer wall of one end of the chain conveying box, and top pressure rollers distributed at equal distances are rotatably connected to the inner wall of the top frame, a second gear is installed on the outer wall of one end of the top pressure roller, and a cylinder is hingedly connected between the frame and the top frame;

[0009] A symmetrically distributed feed rack is welded on one side of the outer wall of the top of the frame, and feed rollers equidistantly distributed are rotatably connected between the two feed racks;

[0010] A discharging rack is welded on the other side of the outer wall at the top of the frame, and a supporting plate is slidably connected to the inner wall of the discharging rack.

[0028] In this embodiment, a cylinder 8 is arranged between the upper and lower leveling structures composed of the chain conveyor box 2, the bottom pressure roller 3 and the first gear 4, the top frame 5, the top pressure roller 6 and the second gear 7. Through the hinge connection between the chain conveyor box 2 and the top frame 5, the cylinder 8 can drive the top frame 5 to rotate, and an opening is formed between the bottom pressure roller 3 and the top pressure roller 6, which increases the operating space and reduces the difficulty of maintenance and cleaning.

[0029] Example 2, refer to Figure 1 A leveling structure for a pickling and leveling machine, wherein a symmetrically distributed feed rack 9 is welded to one side of the top outer wall of a frame 1, and feed rollers 10 distributed at equal distances are rotatably connected between the two feed racks 9.

[0030] In this embodiment, a feed rack 9 and a feed roller 10 are provided at the feeding position. The feed rack 9 and the feed roller 10 are assembled to form a certain slope, which can better meet the feeding requirements of the pickling plate with a certain curvature. The pickling plate can be placed directly on the feed roller 10, freeing both hands, with a high safety factor to prevent scratches on the skin.

[0031] Example 3, refer to Figure 2 A leveling structure for a pickling and leveling machine, a discharging frame 11 is welded on the other side of the top outer wall of the frame 1, and a support plate 12 is slidably connected to the inner wall of the discharging frame 11.

[0032] In this embodiment, a discharging rack 11 and a support plate 12 are provided at the discharging position. The support plate 12 can slide along the inner wall of the discharging rack 11. After the pickling plate is leveled, the support plate 12 can directly support the pickling plate without holding the discharging with hands, thereby maintaining the flatness of the plate and avoiding the problem of the plate bending under the influence of gravity.

[0033] Reference Figure 3 , the first gear 4 and the second gear 7 are meshed with each other.

[0034] Reference Figure 2 A first handle 13 is welded to the outer wall of one side of the support plate 12 .

[0035] Reference Figure 2 A pulley set 15 is installed on the outer wall of one side of one chain conveyor box 2, and a servo motor 14 is installed on the pulley of the pulley set 15.

[0036] Reference Figure 1 The outer wall of the feed roller 10 is slidably connected with symmetrically distributed positioning pieces 16.

[0037] Reference Figure 1-3 A second handle 17 is welded to the top outer wall of the top frame 5 .

[0040] Working principle: First, adjust the distance between the two positioning pieces 16 according to the size of the pickling plate, and then feed the pickling plate into the leveling structure along the slope formed by multiple feed rollers 10. As the servo motor 14 drives the bottom pressure roller 3 to rotate, the first gear 4 on the bottom pressure roller 3 and the second gear 7 on the top pressure roller 6 will engage and rotate with each other. With the continuous rotation of the bottom pressure roller 3 and the top pressure roller 6, the pickling plate can be leveled. Then, the pickling plate coming out of the leveling structure will move to the support plate 12. As the pickling plate is continuously discharged, the support plate 12 will slide along the inner wall of the discharge frame 11 until it is completely discharged. After a period of use, the machine can push the top frame 5 to rotate through the cylinder 8, so that an opening is formed between the bottom pressure roller 3 and the top pressure roller 6, thereby maintaining and cleaning the roller body.
