DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a steel material pretreatment device that is convenient for unloading, comprising a base 1, a conveying frame 2 is fixedly installed on the top of the base 1, a mounting frame 3 is fixedly installed on the top of the base 1 on one side of the conveying frame 2, a grinding roller 4 is rotatably installed inside the mounting frame 3, and a conveying wheel 1 5 is fixedly installed on one end of the grinding roller 4 through the mounting frame 3. A grinding motor 6 is fixedly installed at the bottom of the conveying wheel 1 5 in the bottom of the base 1, a conveying wheel 2 7 is fixedly installed at the output end of the grinding motor 6, and two sets of conveying belts 8 are arranged between the conveying wheel 1 5 and the conveying wheel 2 7. By providing the conveying wheel 1 5 and the conveying wheel 2 7, the grinding motor 6 is started to drive the conveying wheel 2 7 to rotate, and the grinding roller 4 is driven to rotate under the friction between the conveying belt 8 and the conveying wheel 1 5 and the conveying wheel 2 7, so as to grind the surface of the steel plate located on the top surface of the grinding roller 4.

[0020] A concave frame 9 is fixedly installed on the top of the mounting frame 3, and clamping rods 10 are slidably installed at the four corners of the top inside the concave frame 9, and the top ends of the four groups of clamping rods 10 pass through the concave frame 9 and are fixedly installed with a top plate 11, and one end of the four groups of clamping rods 10 located at the bottom of the concave frame 9 is fixedly installed with a clamping frame 12, and the surface of the clamping rod 10 located between the concave frame 9 and the clamping frame 12 is provided with a clamping spring 13, and two groups of mounting columns 14 are fixedly installed at the bottom of the clamping frame 12, and a clamping roller 15 is rotatably installed on the surface of the mounting column 14. Because a clamping spring 13 is provided, when steel plates of different thicknesses pass through the bottom of the clamping frame 12, the clamping frame 12 is pressed down under the rebound action of the clamping spring 13, so that the clamping roller 15 is pressed down and tightly against the top of the steel plate, thereby pressing the steel plate against the top of the grinding roller 4 to ensure that the steel plate located at the top of the grinding roller 4 will not tilt when the steel plate is ground.

[0021] A rectangular groove 16 is provided at the central position of the top of the conveying frame 2. The conveying frame 2 is symmetrically fixed with multiple sets of mounting shafts 17 on both sides of the rectangular groove 16, and a conveying roller 18 is rotatably installed on the surface of the mounting shaft 17. Because the conveying roller 18 is provided, the steel plate is controlled to slide on the conveying roller 18, so that the conveying roller 18 rolls on the bottom of the steel plate, thereby reducing the friction between the conveying roller 18 and the steel plate.

[0022] A conveying screw 19 is rotatably installed inside the rectangular groove 16, and a limiting slide bar 20 is fixedly installed at the bottom of the conveying screw 19 inside the rectangular groove 16. A moving seat 21 is provided on the surface of the conveying screw 19 and the limiting slide bar 20 located inside the rectangular groove 16. By providing the moving seat 21, the moving seat 21 is controlled to push the steel plate to move on the top of the conveying roller 18, thereby controlling the steel plate to pass through the top of the grinding roller 4 for grinding.

[0023] One end of the conveying screw 19 passes through the conveying frame 2 and is fixedly installed with a bevel gear 1 22. A conveying motor 23 is fixedly installed on one side of the base 1 located at the bottom of the bevel gear 1 22, and a bevel gear 2 24 is fixedly installed on the output end of the conveying motor 23, and the bevel gear 2 24 is meshed with the bevel gear 1 22. Because the conveying motor 23 is provided, the forward and reverse rotation of the conveying motor 23 is controlled, and the rotation drives the bevel gear 1 22 to rotate through the bevel gear 2 24, thereby controlling the moving seat 21 to move on the conveying screw 19.

[0024] The working principle of the utility model is:

[0025] The conveying motor 23 is controlled to reverse, so that the movable seat 21 moves on the surface of the conveying screw 19 to the end of the rectangular groove 16 away from the grinding roller 4, and the steel plate is placed on the top of the conveying roller 18 and stuck on one side of the movable seat 21. The conveying motor 23 is controlled to rotate forward, and the rotation is transmitted to the bevel gear 1 22 through the bevel gear 2 24, so that the movable seat 21 pushes the steel plate to move between the grinding roller 4 and the clamping roller 15. Under the elastic action of the clamping spring 13, the clamping frame 12 is pressed down, so that the clamping roller 15 is pressed against the top of the steel plate, and the steel plate is pressed against the top of the grinding roller 4. At the same time, the grinding motor 6 is started, and the conveying wheel 1 5 and the conveying wheel 2 7 are rotated synchronously under the drive of the conveying belt 8, and the grinding roller 4 is controlled to rotate at the bottom of the steel plate, so as to grind the surface of the bottom of the steel plate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
