[0002] Steel plate is a flat steel material made by pouring molten steel and pressing it after cooling. It is flat and rectangular and can be directly rolled or cut from wide steel strip. Thin plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates according to the type of steel.

[0003] Steel plates are prone to rust after being left for a long time, so rust removal equipment is needed to treat the steel plates. Current rust removal equipment usually uses a motor to drive a brush roller to rotate, so that the brush on the brush roller contacts the surface of the steel plate to remove rust. However, after a period of use, the wear of the brush will cause the thickness to decrease, resulting in less contact with the surface of the steel plate, which in turn affects the rust removal effect. Therefore, a steel plate rust removal device is urgently needed to be developed. Utility Model Content

During the entire process of each brush strip contacting the upper surface of the steel plate, under the action of a pair of compression springs, the brush strip can always abut against the upper surface of the steel plate. When the thickness of the brush strip is thinned, the contraction and extension of the compression spring will also be reduced accordingly. Under the elastic force of the compression spring, the thinned brush strip can still contact the upper surface of the steel plate to ensure the rust removal effect.

[0016] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0017] In the present invention, the motor 2 is connected to the external electric control system through a wire. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0018] According to the instruction manual Figure 1-2 It can be seen that when the present invention is in use, the steel plate is transported by the conveyor belt 13, so that the steel plate moves slowly under the cover body 1, the motor 2 is started, and the output end of the motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the rotating drum 4 to rotate, and the rotating drum 4 drives the multiple groups of rust removal components arranged thereon to rotate. When the rotating drum 4 drives the brush strip 12 in the rust removal component to abut against the upper surface of the steel plate, the brush strip 12 makes the connected fixed strip 11 move toward the direction inside the rotating drum 4, and the fixed strip 11 drives the connected transmission plate 10 to move, and the transmission plate 10 drives the connected pair of sliding strips 9 to slide in a pair of limit shells 5, thereby compressing the compression spring. When the transmission plate 10 is in a vertical state, the compression amount of the compression spring reaches the maximum. When the motor 2 continues to drive the rotating drum 4 to rotate, the compression spring extends, and the compression The compression springs enable a pair of slide bars 9 to drive the transmission plate 10, the fixed bar 11 and the brush bar 12 to move toward the outside of the rotating drum 4. The slide bar 9 can always be in contact with the upper surface of the steel plate during the entire movement process, and the motor 2 drives the multiple brush bars 12 on the rotating drum 4 to rotate to remove rust from the upper surface of the steel plate on the transmission belt 13; the utility model drives the multiple brush bars 12 to rotate through the motor 2. During the entire process when each brush bar 12 contacts the upper surface of the steel plate, under the action of a pair of compression springs, the brush bar 12 can always abut against the upper surface of the steel plate. When the thickness of the brush bar 12 is thinned, the contraction and extension of the compression spring will also be reduced accordingly. Under the elastic force of the compression spring, the thinned brush bar 12 can still be in contact with the upper surface of the steel plate to ensure the rust removal effect.

[0019] There is a possible implementation, where each rotating rod 6 is provided with a threaded portion of the rotating rod 6 located inside the limit housing 5 and close to the limit block 7, and the threaded portion of the rotating rod 6 is threadedly connected to a slider 8, and one end of the compression spring abuts against the side of the slider 8 away from the limit block 7. The cross-sections of the limit housing 5 and the slider 8 are both rectangular. When the threaded rod is rotated, the slider 8 moves inside the limit housing 5, thereby adjusting the clamping force of the compression spring. A locking member can be provided on the rotating drum 4 to prevent the rotating rod 6 from rotating.

[0020] In one possible implementation, the brush strip 12 is fixed to the fixing strip 11 by means of bolts, so that the brush strip 12 can be easily replaced when it is severely worn.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
