[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Reference Figure 1-5, a steel belt grinder disclosed in the utility model, including a steel belt grinder body 1, a fixed frame 2, a top roller 3, a side roller 4, a horizontal rod 5, a stabilizing hole 6, an extension plate 7, a bottom bolt 8, a pulley support leg 9, a side limit groove 10, a horizontal bolt 11, a locking nut 12, a movable frame 13, a top threaded rod 14, a top plate 15, a vertical limit roller 16, a side threaded rod 17, a side plate 18 and a horizontal limit roller 19, a horizontal rod 5 is fixed on one side of the steel belt grinder body 1, and the horizontal rod 5 is in contact with the inner wall of the stabilizing hole 6, and the stabilizing hole 6 is arranged on the horizontal plane where the center of the extension plate 7 is located, a bottom bolt 8 is threadedly installed on one end of the bottom surface of the extension plate 7, and a pulley support is fixed on the other end of the bottom surface of the extension plate 7 The support legs 9 and the side of the extension plate 7 are provided with a side limit groove 10, the inner wall of the side limit groove 10 is fitted with one end of the horizontal bolt 11, and the other end of the horizontal bolt 11 is installed with a locking nut 12, and the middle part of the horizontal bolt 11 passes through the hole opened at the bottom of the movable frame 13, the top of the movable frame 13 is threadedly installed with a top threaded rod 14, and the bottom end of the top threaded rod 14 is rotatably connected to the top surface of the top plate 15 through a bearing seat, and a vertical limit roller 16 is rotatably installed at the bottom of the top plate 15, a side threaded rod 17 is threadedly installed in the middle of the vertical part of the movable frame 13, and the side threaded rod 17 is rotatably connected to one side of the side plate 18 through the end bearing seat, and a horizontal limit roller 19 is rotatably installed on the other side of the side plate 18.

[0026] In this example, fixed frames 2 are symmetrically installed at both ends of the top surface of the steel belt grinder body 1, and a top roller 3 is rotatably installed on the inner top surface of the fixed frame 2, and a side roller 4 is rotatably installed on the inner side surface of the fixed frame 2. The above-mentioned structural design can limit and guide the steel belt from the inlet and outlet ports on both sides of the steel belt grinder body 1 to prevent the movement of the steel belt from causing damage to nearby operators.

[0027] The horizontal rod 5 and the stabilizing hole 6 are slidably connected, and the horizontal rod 5 and the stabilizing hole 6 are horizontally symmetrically distributed about the center of the extension plate 7, and the horizontal rod 5 and the bottom bolt 8 are on the same vertical plane. The above structural design enables the extension plate 7 to carry the stabilizing hole 6 to perform stable horizontal displacement along the horizontal rod 5, thereby adjusting the distance between the extension plate 7 and the feed port of the steel belt grinder body 1.

[0028] The side view sections of the side limit groove 10 and the horizontal bolt 11 are both "T"-shaped, and the side limit groove 10 and the horizontal bolt 11 are both horizontally symmetrically distributed about the center of the movable frame 13. The above-mentioned structural design can prevent the horizontal bolt 11 from slipping off the side limit groove 10, and ensure that the horizontal bolt 11 can carry the movable frame 13 along the side limit groove 10 for stable horizontal sliding displacement.

[0029] The bottom of the inner side surface of the vertical part of the movable frame 13 is in contact with the side surface of the extension plate 7, and the movable frame 13 is distributed at equal intervals. The above structural design ensures the stability of the movable frame 13 during use and adjustment. The equal-interval distribution allows the vertical limiting roller 16 and the horizontal limiting roller 19 to perform multi-point extrusion and limiting on the steel belt, thereby improving the flattening and limiting effects on the steel belt.

[0030] The top threaded rods 14 are horizontally symmetrically distributed about the center of the top plate 15, and vertical limiting rollers 16 are installed at equal intervals at the bottom of the top plate 15. The above-mentioned structural design enables the top threaded rods 14 to push the top plate 15 and the vertical limiting rollers 16 to move vertically stably when rotating, so that the vertical limiting rollers 16 can stably flatten the steel strip vertically.

[0031] The length of the vertical limiting roller 16 is smaller than that of the top roller 3, and horizontal limiting rollers 19 are symmetrically distributed on both sides of the vertical limiting roller 16. The above structural design can avoid the collision between the vertical limiting roller 16 and the horizontal limiting roller 19, and stably limit the steel belt vertically and horizontally.

[0032] The side threaded rods 17 are vertically symmetrically distributed about the center of the side plate 18, and horizontal limiting rollers 19 are installed at equal intervals on the sides of the side plate 18. The above-mentioned structural design enables the side threaded rods 17 to push the side plate 18 and the horizontal limiting rollers 19 to perform stable horizontal displacement when rotating, so that the horizontal limiting rollers 19 symmetrically distributed about the vertical limiting rollers 16 can perform stable horizontal limiting on steel strips of different widths.

[0033] The working principle and beneficial effects of the utility model are as follows: when using the device, firstly adjust the horizontal position of the extension plate 7 according to the specifications of the steel strip to be processed; if the overall size of the steel strip is long and the bending degree after unwinding is large, Figure 2 The bottom bolt 8 in the middle is screwed down, and the bottom bolt 8 no longer squeezes the horizontal rod 5 and is fixed to the extension plate 7, pushing the extension plate 7 to move horizontally away from the steel belt grinding machine body 1, and the extension plate 7 with the stabilizing hole 6 slides stably along the horizontal rod 5 until the position of the extension plate 7 is appropriate, and the bottom bolt 8 is screwed up to reset, and the bottom bolt 8 squeezes the horizontal rod 5 and is fixed to the extension plate 7;

[0034] Then will Figure 4 The locking nuts 12 installed at the ends of the horizontal bolts 11 symmetrically distributed in the middle rotate away from the outer side of the bottom of the movable frame 13, and the locking nuts 12 no longer squeeze the movable frame 13 and are tightly fixed to the side of the extension plate 7, and then the movable frame 13 is pushed along with the horizontal bolts 11 Figure 1 The side limit groove 10 in the middle slides horizontally until the spacing between adjacent movable frames 13 is appropriate, and the locking nut 12 is rotated to reset, and the locking nut 12 squeezes the movable frame 13 to fix it;

[0035] Then the steel strip to be processed is passed from right to left through the inner side of the movable frame 13 and Figure 1 On the inner side of the fixed frame 2 on the right side, the end of the steel strip is fed into the steel strip grinder body 1, and then the side threaded rod 17 installed on one side of the movable frame 13 is rotated in the same direction at the same time, so that the side threaded rod 17 is screwed into the movable frame 13, and the side threaded rods 17 symmetrically distributed on the left and right sides stably push the symmetrically distributed side plates 18 and the horizontal limiting rollers 19 to move horizontally toward the center of the movable frame 13 until the horizontally symmetrically distributed horizontal limiting rollers 19 are in contact with both sides of the steel strip, stop rotating the side threaded rods 17, and use the thread self-locking to fix the horizontal positions of the side threaded rods 17, the side plates 18 and the horizontal limiting rollers 19, so as to stably limit the horizontal position of the steel strip;

[0036] Then, the symmetrically distributed top threaded rods 14 rotate in the same direction at the same time, and the top threaded rods 14 rotate downward to push the top plate 15 and the vertical limiting roller 16 to move vertically downward. During the downward movement, the bottom end of the vertical limiting roller 16 contacts the top surface of the bent steel strip and continues to press downward to squeeze the bent steel strip downward to make the steel strip flat. The rotation of the top threaded rod 14 is stopped, and the height of the top plate 15 and the vertical limiting roller 16 is fixed by thread self-locking. The vertical limiting rollers 16 installed in the multiple movable frames 13 continue to stably squeeze the steel strip vertically to keep the steel strip flat. The steel strip grinder body 1 is started, and the steel strip grinder body 1 grinds the surface of the steel strip and outputs the steel strip horizontally to the left. The steel strip passes through the inside of the fixed frame 2 on the left and is stably output to the left under the action of the top roller 3 and the side roller 4, thereby achieving continuous and efficient steel strip grinding.

[0037] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
