Strip steel, also known as steel belt, is up to 1300mm wide, with lengths varying slightly depending on the size of the coil.

[0003] After the strip steel goes through hot rolling production, there will be excess burrs and oxidized iron sheets on the surface of the initial finished product. The grinder can grind the upper and lower surfaces of the strip steel, but the side edges of the strip steel are not easy to grind due to their thickness and small area. Manual grinding is inefficient.

[0004] Therefore, it is necessary to propose a strip edge grinding device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a strip edge grinding device to solve the problem that after the strip is hot rolled, there will be excess burrs and oxidized iron scale on the surface of the preliminary finished product. The grinder can grind the upper and lower surfaces of the strip, but the edge of the side of the strip is not easy to grind due to its small thickness and area, and manual grinding is used with low efficiency.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1 - Figure 3 The strip edge grinding device shown includes a conveyor frame 1, and the conveyor frame 1 is internally driven with a conveyor belt 2, on which a strip body 3 is conveyed. Since the strip body 3 is generally long and heavy, the strip body 3 needs to be conveyed by the conveyor belt 2.

[0021] After the strip steel body 3 is produced, burrs will likely appear on the edge. Therefore, connecting frames 5 are fixed on both sides of the conveyor frame 1. Grinding mechanisms 4 are installed on the opposite sides of the two connecting frames 5. The bottom ends of the two grinding mechanisms 4 are attached to the edge of the upper surface of the strip steel body 3. The grinding mechanisms 4 include side plates 9. A motor 8 is fixed on the side of the side plate 9 close to the corresponding connecting frame 5. The other side of the side plate 9 is rotatably connected to three rotating shafts 13. The three rotating shafts 13 are distributed in a herringbone shape. One of the rotating shafts 13 arranged at the top is connected to the drive shaft of the motor 8. The outer sides of the three rotating shafts 13 are connected to the grinding crawlers 15. When the motor 8 is started, it drives the movable rotating shaft 13 to rotate, thereby rotating the grinding crawlers 15. A grinding effect is achieved.

[0022] A bottom plate 16 is fixed to the bottom end of the side plate 9 close to the strip steel body 3 , and a sandpaper 10 is fixed to the side of the bottom plate 16 close to the strip steel body 3 , and the sandpaper 10 rubs against the edge of the strip steel body 3 .

[0023] A clamping frame 11 is provided in the middle of the grinding track 15, and a clamping roller 12 is connected to the inner rotation of the clamping frame 11. The outer ring of the clamping roller 12 is pressed against the inner side of the grinding track 15, and the lower surface of the grinding track 15 is attached to the upper surface of the strip steel body 3. The clamping roller 12 is used to clamp the grinding track 15 to prevent the grinding track 15 from loosening during rotation.

[0024] Two electric push rods 7 are fixed to the top of the connecting frame 5 , and a lifting block 14 is fixed to the bottom of the two electric push rods 7 . One side of the side plate 9 is fixed to the lifting block 14 .

[0025] In the actual operation of the present invention, when the strip steel body 3 moves close to the grinding mechanism 4, the electric push rod 7 can be started and extended downward to drive the grinding mechanism 4 to descend, so that the lower surface of the rotating grinding track 15 can fit and rub against the upper surface of the strip steel body 3 to grind the edge of the upper surface of the strip steel body 3. At the same time, since the grinding track 15 is distributed in a herringbone shape, the contact area between the lower surface and the strip steel body 3 is large. After grinding the burrs and oxidized iron sheets, it can be lowered to press and fix the strip steel body 3 to avoid the strip steel body 3 from deflecting during grinding.

[0026] Furthermore, the descent of the grinding mechanism 4 will drive the sandpaper 10 to descend, and since the strip steel body 3 moves on the conveyor belt 2, the edge of the strip steel body 3 will rub against the sandpaper 10 during the movement, completing the grinding of burrs and iron oxide scale on the side of the conveyor belt 2. Moreover, since the grinding work is carried out during the movement and transportation of the strip steel body 3, production efficiency can be improved and time can be saved.

[0027] It should be noted that the steel strip body 3 itself is heavy and long. During the grinding process, the downward pressure of the grinding track 15 will not affect the forward and backward transportation of the steel strip body 3 on the conveyor belt 2.

[0028] Fixed blocks 6 are fixed on both sides of the long side of the conveyor frame 1, and the connecting frame 5 is fixed to one side of the corresponding fixed block 6. The two grinding mechanisms 4 are of the same height and are parallel to each other along the short side of the conveyor belt 2.
