[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, 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.

[0030] See also Figure 1-5 In the embodiment of the present utility model, the automatic deviation-correcting device for the conveyor belt includes a transmission rod 1, a positioning mechanism 2, an adjustment mechanism 3, and a connecting block 5;

[0031] The transmission rod 1 can support the conveyor belt, and the positioning mechanism 2 is arranged at one end of the transmission rod 1, and the positioning mechanism 2 can limit the position of one end of the transmission rod 1;

[0032] The adjustment mechanism 3 is provided at the other end of the transmission rod 1 and includes a second positioning seat 31. A driving assembly 33 is provided on one side of the second positioning seat 31. A fixing frame 32 capable of supporting the driving assembly 33 is fixedly connected to the side of the second positioning seat 31. The output end of the driving assembly 33 is transmission-connected to an elastic coupling 34. The elastic coupling 34 is transmission-connected to an adjusting screw 36. The side of the adjusting screw 36 is screwed and connected to a sliding block 35 that is slidably connected to the inner side of the second positioning seat 31.

[0033] The connecting block 25 is slidably connected to the inner side surface of the positioning seat 231, and the side surface of the connecting block 25 is rotatably connected to the inner side surface of the other end of the transmission rod 1. A circular hole 252 is opened on the side surface of the connecting block 25. The top and bottom inner sides of the connecting block 25 are rotatably connected to the rotating shaft 251 that is rotatably connected to the inner side surface of the sliding block 35. The connecting block 25 and the sliding block 35 can be connected to each other through the rotating shaft 251, and the adjusting screw 36 passes through the inside of the circular hole 252.

[0034] When the adjusting screw rod 36 rotates, the sliding block 35 can move along the adjusting screw rod 36. Since the adjusting screw rod 36 and the driving assembly 33 are connected by the elastic coupling 34, the adjusting screw rod 36 can be offset by a certain angle relative to the output shaft of the driving assembly 33, and the sliding block 35 and the connecting block 2 5 are rotatably connected by the rotating shaft 2 51, the sliding block 35 can push the connecting block 2 5 to move, so that the driving rod 1 and the connecting block 2 5 can rotate smoothly. When the conveyor belt deviates, the positive and negative rotation of the adjusting screw rod 36 can be used to make the sliding block 35 drive the connecting block 2 5 to move back and forth, thereby making the driving rod 1 swing back and forth in a small range to correct the deviation of the conveyor belt, thereby realizing automatic deviation correction of the conveyor belt, which is beneficial to the normal use of the conveyor belt.

[0035] The aperture of the cylindrical section of the sliding block 35 corresponding to the inside of the circular hole 52 can be set larger, so that there is a certain gap between the cylindrical section of the sliding block 35 and the inner wall of the circular hole 52. In this way, the connecting block 2 5 can rotate in a small range relative to the sliding block 35, so that the transmission rod 1 and the connecting block 2 5 can rotate smoothly. The adjustment mechanism 3 includes a motor and a gear box. The gear box is fixedly connected to the fixed frame 32. The output end of the motor is connected to the input end of the gear box. The output end of the gear box is connected to the elastic coupling 34. There is a set of two bevel teeth inside the gear box.

[0036] Example 1

[0037] like Figure 1-2 As shown, in this embodiment, the transmission rod 1 is equipped with a deviation correction sensor 6.

[0038] During specific implementation, the correction sensor 6 can be set on the cutting machine so that the edge of the conveyor belt passes through the inside of the correction sensor 6. The correction sensor 6 detects whether the conveyor belt is deviated. After the correction sensor 6 detects that the conveyor belt is deviated, the transmission rod 1 is swung back and forth through the adjustment mechanism 3 to correct the conveyor belt.

[0039] like Figure 2-3 As shown, in this embodiment, the inner side surface of one end of the transmission rod 1 is rotatably connected to a connecting block 4, a circular hole 42 is opened on the side surface of the connecting block 4, and the inner side surface of the connecting block 4 is rotatably connected to a rotating shaft 41;

[0040] The positioning mechanism 2 includes a positioning seat 21 and a positioning screw 22;

[0041] The positioning seat 21 is located at one end of the transmission rod 1. The inner side of the positioning seat 21 is slidably connected to the side of the connecting block 4. The positioning screw 22 is arranged inside the positioning seat 21. The positioning screw 22 passes through the inside of the circular hole 42 and is screwed together with the inner side of the rotating shaft 41. The positioning screw 22 can pass through the inside of the circular hole 42. The connecting block 4 is restricted inside the positioning seat 21 by the positioning screw 22 and the rotating shaft 41.

[0042] The diameter of the first circular hole 42 is larger than the diameter of the positioning screw 22 , and the diameter of the second circular hole 52 is larger than the diameter of the adjusting screw 36 .

[0043] During specific implementation, the positioning seat 21 can be fixed on the cutting machine, and the position of the rotating shaft 41 can be limited by the positioning screw 22, and the connecting block 4 can rotate around the rotating shaft 41. When the sliding block 35 pushes the connecting block 25 to move, the connecting block 25 and the transmission rod 1 can rotate around the rotating shaft 41. In this way, the transmission rod 1 can be swung back and forth by adjusting the forward and reverse rotation of the screw 36, thereby adjusting the position of the conveyor belt. The aperture of the circular hole 42 is larger than the diameter of the positioning screw 22, so that the connecting block 4 can rotate smoothly relative to the positioning screw 22.

[0044] Example 2

[0045] Based on the first embodiment, Figure 3 As shown, in this embodiment, the positioning mechanism 2 further includes a nut 23 and a torsion block 24;

[0046] The nut 23 is screwed onto the positioning screw 22, and the torsion block 24 is fixedly connected to one end of the positioning screw 22 outside the positioning seat 21. The torsion block 24 can be against the side of the positioning seat 21, and the nut 23 can be against the inner side of the positioning seat 21.

[0047] During specific implementation, the positioning screw 22 can be restricted on the positioning seat 21 by the positioning seat 21 and the nut 23. After the nut 23 is loosened, the positioning screw 22 can be rotated by the torsion block 24. When the positioning screw 22 rotates, the rotating shaft 41 can drive the connecting block 4 to move, so that one end of the transmission rod 1 can be adjusted to a suitable position as needed. At the same time, the adjusting screw 36 can be driven to rotate by the driving component 33, so that the sliding block 35 pushes the connecting block 25 to move, and the other end of the transmission rod 1 is adjusted to the corresponding position, so that the transmission rod 1 tightens the conveyor belt. After the adjustment is completed, the nut 23 can be tightened so that the torsion block 24 and the nut 23 clamp the side wall of the positioning seat 21, thereby limiting the position of the positioning screw 22, and limiting the position of the connecting block 4 by the rotating shaft 41, thereby limiting one end of the transmission rod 1.
