Description

Technical Field

[0001] The utility model relates to the technical field of steel strip descaling, in particular to a steel strip high-efficiency descaling device. Background Art

[0002] During the production and storage of steel strips, the surface is oxidized by contact with air, forming an oxide layer, which needs to be removed, that is, descaling.

[0003] The descaling treatment of steel strips can be carried out by sandblasting or chemical cleaning. Sandblasting is expensive and easily forms small pits on the surface of the steel strip. Chemical cleaning of steel strips is also easy to damage the steel strip body. In the prior art, the utility model patent with application number 2022209615336 discloses a three-roller descaling brush roller device, which can bend and brush the steel strip to remove the oxide layer on the surface. However, during the brushing process, the hard bristles are also easy to form scratches on the surface of the steel strip, affecting the quality of the steel strip surface, which needs to be improved.

[0007] Wherein, the first guide roller and the third guide roller are located at the same height.

[0008] Among them, the position height of the scale breaking roller is higher than the position height of the first guide roller and the third guide roller.

[0009] Wherein, the third guide frame is provided with a first reduction motor for driving the third guide roller to rotate.

[0010] Wherein, a second reduction motor for driving the descaling roller to rotate is arranged on the second guide frame.

[0011] The steel strip is transported through the first guide roller, the second guide roller and the third guide roller in sequence, and the rubber roller intermittently strikes the steel strip as the descaling roller rotates.

[0012] The beneficial effects of the utility model include: a highly efficient steel strip descaling device, which bends the steel strip during conveying through the first guide frame, the second guide frame and the third guide frame, and conveys it in a wave shape, so as to achieve the peeling or loosening of the oxide layer on the surface of the steel strip, and utilizes the rubber roller on the descaling drum to intermittently strike the steel strip, thereby inducing the oscillation of the steel strip, promoting the shedding of the oxide layer, and avoiding damage to the surface of the steel strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] Figure 2 yes Figure 1 A partial enlarged view of part A. DETAILED DESCRIPTION

[0015] Combine the following Figure 1-2 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1 The steel strip efficient descaling device shown is used for descaling the steel strip 5, and comprises: a fixed seat 4, a first guide frame 1, a second guide frame 2, a third guide frame 3 and a descaling roller 6. The first guide frame 1, the second guide frame 2 and the third guide frame 3 are sequentially arranged on the fixed seat 1 in a front-to-back arrangement. The bottoms of the first guide frame 1, the second guide frame 2 and the third guide frame 3 can be fixed to the fixed seat 1 with screws, and the structure is relatively stable.

[0017] A first guide roller 7 is arranged on the first guide frame 1, a second guide roller 8 is arranged on the second guide frame 2, and a third guide roller 9 is arranged on the third guide frame. The steel belt 5 is transported through the first guide roller 7, the second guide roller 8 and the third guide roller 9 in sequence. A first reduction motor 11 for driving the third guide roller 9 to rotate is arranged on the third guide frame 3, and the third guide roller 9 actively rotates to pull the steel belt 5.

[0018] In this embodiment, the first guide roller 7 and the third guide roller 9 are located at the same height, and the second guide roller 8 is located at a higher height than the first guide roller 7 and the third guide roller 9, so that the steel belt 5 is bent during the conveying process and conveyed in a wave shape, causing the oxide layer on the surface of the steel belt 5 to warp or loosen.

[0019] The descaling roller 6 is disposed on the second guide frame 2 and is located below the second guide roller 8. In the present embodiment, a second reduction motor 10 for driving the descaling roller 6 to rotate is disposed on the second guide frame 2 to actively rotate the descaling roller 6.

[0020] like Figure 2 As shown, ear seats 14 are circumferentially spaced apart at both ends of the descaling roller 6, and a rubber roller 13 is arranged between the ear seats at both ends of the descaling roller 6. The surface of the rubber roller 13 is wrapped with a rubber sleeve, which has abundant elasticity. The rubber roller 13 intermittently strikes the steel strip 5 as the descaling roller 6 rotates, which can induce the oscillation of the steel strip 5 and promote the shedding of the oxide layer, and can also avoid the damage to the surface of the steel strip 5.

[0021] A slide groove 12 extending radially along the descaling roller 6 is provided in the ear seat 14, and a bearing 15 corresponding to the end of the rubber roller 13 is provided in the slide groove 12 to support the rotation of the rubber roller 13 and the movement along the radial direction of the descaling roller 6. During the rotation of the descaling roller 6, the rubber roller 13 moves outward under the action of centrifugal force, and moves inward when encountering resistance when hitting the steel strip 5, thereby avoiding the problem of excessive impact force on the steel strip 5.

[0022] like Figure 1 As shown, the position height of the descaling roller 6 is higher than the position height of the first guide roller 7 and the third guide roller 9, and the height difference between the second guide roller 8 and the first guide roller 7 is relatively large. The impact of the rubber roller 13 on this section of the steel strip can induce high-frequency oscillation to promote the shedding of the oxide layer.

[0023] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
