DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Example 1, please refer to Figure 1-7 The utility model provides a technical solution: an anti-belt deviation device, including a fixed frame 1, a motor 4 is fixedly connected to the surface of the fixed frame 1, the output end of the motor 4 is rotatably connected to the inside of the fixed frame 1, the inside of the fixed frame 1 is rotatably connected to a conveying roller 8, and two conveying rollers 8 are provided, the output end of the motor 4 is fixedly connected to one of the conveying rollers 8, the surfaces of the two conveying rollers 8 are transmission-connected to a conveying belt 5, a fixed plate 6 is fixedly connected to the surface of the fixed frame 1, a fixed block 9 is fixedly connected to the surface of the fixed plate 6, a limiting groove 10 is provided on the surface of the fixed block 9, a threaded rod 7 is rotatably connected to the surface of the fixed block 9, and the threaded rod 7 penetrates into the inside of the limiting groove 10, a sliding block 11 is slidably connected to the inner wall of the limiting groove 10, the inside of the sliding block 11 is threadedly connected to the surface of the threaded rod 7, a conveying roller 2 12 is rotatably connected to the surface of the sliding block 11, and the conveying roller 2 12 is transmission-connected to the conveying belt 5.

[0025] When the staff rotates the threaded rod 7, due to the setting of the limiting groove 10, the sliding block 11 does not rotate with the threaded rod 7, but slides inside the limiting groove 10 as the threaded rod 7 rotates, and then the sliding block 11 drives the conveying roller 2 12 to move, and the movement of the conveying roller 2 12 stretches the conveying belt 5, so that the conveying belt 5 is tightened, and then the threaded rod 7 is rotated to drive the conveying roller 2 12 to move, so as to adjust the tightness of the conveying belt 5, so as to avoid the conveying belt 5 being too loose during use and affecting the use of the device, thereby improving the use effect of the device.

[0026] Two baffles 2 are fixedly connected to the surface of the fixed frame 1, and the two baffles 2 are respectively located on both sides of the conveyor belt 5. The surface of the baffle 2 is rotatably connected with equidistantly arranged rotating rods 3, and then the position of the conveyor belt 5 is limited by the setting of the baffle 2 and the rotating rod 3, thereby avoiding the conveyor belt 5 from running off the track during the rotation process. At the same time, due to the setting of the rotating rod 3, the friction of the conveyor belt 5 during rotation is reduced, the damage to the conveyor belt 5 is reduced, and the service life of the conveyor belt 5 is extended.

[0027] The surfaces of the two conveying rollers 8 are fixedly connected with gears 13, and the gears 13 are set as incomplete gears, that is, the surfaces of the gears 13 are not fully covered with teeth. The surface of the fixed frame 1 is fixedly connected with a fixed block 2 16, and the fixed block 2 16 is internally slidably connected with a rack 14 and a rack 2 15, and the rack 14 and the rack 2 15 are respectively meshed and connected with the gears 13 on the surfaces of the two conveying rollers 8. The fixed block 2 16 is internally fixedly connected with two springs 18, and the ends of the two springs 18 away from the fixed block 2 16 are respectively fixedly connected with the rack 14 and the rack 2 15. The fixed block 2 16 is internally slidably connected with a movable rod 17, and both sides of the top of the movable rod 17 are set in an inclined shape. The fixed block 2 16 is internally fixedly connected with a spring 2 19, and the end of the spring 2 19 away from the fixed block 2 16 is fixedly connected with the movable rod 17. When the rack 14 blocks the movable rod 17, the spring 2 19 is in a compressed state. The fixed frame 1 is internally fixedly connected with a gong 20.

[0028] When the motor 4 is started, the output end of the motor 4 drives the conveying roller 8 to rotate, and the conveying roller 8 rotates to drive the conveying belt 5 to rotate, and then the conveying belt 5 drives another conveying roller 8 to rotate. When the two conveying rollers 8 rotate, the gear 13 on the surface thereof is driven to rotate accordingly, and the two gears 13 rotate to drive the rack 14 and the rack 2 15. When the rack 14 and the rack 2 15 move, the spring 18 on the surface thereof will be compressed. Since the gear 13 is set as an incomplete gear, when the two gears 13 rotate to separate from the rack 14 and the rack 2 15, the rack 14 and the rack 2 15 will be automatically reset under the elastic force of the spring 18. At the same time, since the two conveying rollers 8 rotate synchronously, the rack 14 and the rack 2 15 move together to block the movement of the movable rod 17, so that when the device is operating normally, the movable rod 17 will not strike the gong 20, thereby ensuring the normal operation of the device.

[0029] When the conveyor belt 5 is loose, it will cause the conveyor belt 5 and the two conveyor rollers 8 to slip, so that the two conveyor rollers 8 will not rotate synchronously. Since one of the conveyor rollers 8 is fixedly connected to the output end of the motor 4, the motor 4 will drive the conveyor roller 8 fixed to the output end to rotate. The movement of the conveyor roller 8 drives the rack 14 to move. The movement of the rack 14 compresses the spring 18 fixed on its surface. At this time, the surface of the other conveyor roller 8 slides with the conveyor belt 5 and will not move synchronously with the other conveyor roller 8, so that the rack 14 is separated from the rack 2 15. The movement of the rack 14 no longer blocks the movable rod 17. Under the elastic force of the spring 2 19, the movable rod 17 moves toward the inner side of the fixed block 2 16 The part moves and strikes the gong 20. After the gear 13 of the rack 14 rotates and disengages, it will move to the inside of the fixed block 16 and reset under the action of the spring 18. Due to the inclined setting of the movable rod 17, the rack 14 squeezes the inclined surface of the movable rod 17, and then the movable rod 17 moves to the outside of the fixed block 16. At the same time, the movable rod 17 moves to squeeze the spring 2 19 again, and then the motor 4 drives the conveying roller 8 to rotate, so that the gear 13 drives the rack 14, and then under the elastic force of the spring 2 19, the movable rod 17 will strike the gong 20 again to repeat the above process, so that the gong 20 makes a sound to remind outsiders to check the conveying belt 5 to avoid the loosening of the conveying belt 5 affecting the operation of the equipment.

[0030] Working principle: When the staff rotates the threaded rod 7, due to the setting of the limiting groove 10, the sliding block 11 will not rotate with the threaded rod 7, but will slide inside the limiting groove 10 as the threaded rod 7 rotates, and then the sliding block 11 drives the conveying roller 2 12 to move, and the movement of the conveying roller 2 12 stretches the conveying belt 5, so that the conveying belt 5 is tightened, and then the threaded rod 7 is rotated to drive the conveying roller 2 12 to move, so as to adjust the tightness of the conveying belt 5.
