DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3 The conveyor belt deviation correction device shown in the figure includes a connecting plate 1 and a rotating roller 2 (the rotating roller 2 is driven by a driving motor, which is a prior art and will not be repeated here). Two connecting plates 1 are provided, and a conveyor belt 3 is sleeved on the rotating roller 2. A first groove 4 is provided on the connecting plate 1. The connecting plate 1 is located on one side of the first groove 4 and is fixedly connected to a first motor. A first screw 5 is fixedly connected to the output end of the first motor. A first slider 6 is threadedly connected to the first screw 5. The first motor stops running synchronously, and can control the two first screws 5 to rotate synchronously, and drive the first sliders 6 to be relatively close or relatively far away. Auxiliary rollers 7 are rotatably connected to the two opposite first sliders 6. A second groove 8 is provided on the connecting plate 1. The connecting plate 1 is located on the upper side of the second groove 8 and is fixedly connected to the second motor The output end of the second motor is fixedly connected with a second screw rod 9, and a second slider 10 is threadedly connected to the second screw rod 9. The second motor drives the second screw rod 9 to rotate and moves the second slider 10. Both sides of one end of the second slider 10 that are away from each other are fixedly connected with forward and reverse motors. The output ends of the forward and reverse motors are fixedly connected with thread rollers 11, and the thread rollers 11 are in contact with the conveyor belt 3. Both sides of the upper end of the connecting plate 1 are fixedly connected with fixed frames 12, and both sides of the bottom end of the fixed frame 12 are fixedly connected with distance sensors 13. The distance sensor 13 monitors the edge position of the conveyor belt 3. When the conveyor belt 3 deviates, it will generate an electrical signal to the controller of the forward and reverse motors, and control the forward and reverse motors to rotate forward or reverse, so as to achieve the effect of correcting the deviation. The distance sensor 13 corresponds to the conveyor belt 3.

[0018] Among them, the pressure roller 17 is rotatably connected between the two opposite third sliders 16, the third slider 16 is sleeved with the plug rod 15, the plug rod 15 is fixedly connected in the third groove 14 of the connecting plate 1, and the third groove 14 is located on the connecting plate 1. By setting the pressure roller 17, a buffer limit can be provided on the upper side of the conveyor belt 3, so as to facilitate the wrinkles generated during the deviation correction to affect the transmission of the conveyor belt 3.

[0019] The third slider 16 and the third groove 14 are fixedly connected to the two ends of the spring respectively. The spring is sleeved on the insertion rod 15 to apply a force to the third slider 16 to improve the stability of the pressure roller 17.

[0020] Among them, the conveyor belt 3 is in contact with the buffer sleeve 18, and the buffer sleeve 18 is sleeved on the pressure roller 17. The buffer sleeve 18 is made of rubber material. By setting the buffer sleeve 18, the buffer effect can be increased, so that the force generated during the deviation correction affects the operation stability of the conveyor belt 3.

[0021] Among them, a cushion block 19 is fixedly connected to the upper side of the connecting plate 1, and the cushion block 19 is in contact with the inner side of the conveyor belt 3. By setting the cushion block 19, the stability of the upper side of the conveyor belt 3 when being rotated by the rotating roller 2 can be improved.

[0022] Working principle: The rotating roller 2 rotates to drive the conveyor belt 3 to move. When the distance sensor 13 detects a distance change (when the distance sensor 13 detects the distance between it and the pad 19), it will control the first motor to rotate so that the two first screws 5 rotate, and the first slider 6 moves relatively. At this time, the bottom side of the conveyor belt 3 is in a loose state. At this time, the second motor drives the second screw 9 to rotate, and moves the second slider 10 upward, controlling the conveyor belt 3 to tighten again. At this time, the two forward and reverse motors drive the threaded rollers 11 to rotate relatively, which can realize the deviation correction of the conveyor belt 3.
