DETAILED DESCRIPTION

[0020] The present application will be further described below in combination with the drawings and specific embodiments. Embodiment 1

[0021] A highly sensitive and powerful belt deviation automatic correction structure, such as Figure 1 As shown, it includes a first longitudinal beam 1 and a second longitudinal beam 2 aligned front to back, a first crossbeam 3 and a second crossbeam 4 perpendicular to the first longitudinal beam 1 are fixed in sequence from left to right between the first longitudinal beam 1 and the second longitudinal beam 2, a roller frame 5 is rotatably connected to the middle of the first crossbeam 3, the roller frame 5 is U-shaped, and rollers 6 are installed on the roller frame 5; the number of rollers 6 is set to two, and the two rollers 6 are in an inverted eight shape.

[0022] like Figure 1 As shown, a hinged rod 8 is hinged in the middle of the second crossbeam 4, and the middle part of the hinged rod 8 is hinged to the second crossbeam 4 through a hinged seat 12. A first fixed plate 7 facing horizontally to the right is fixed to the right side of the lower part of the roller frame 5. The first fixed plate 7 is fixed to the left end of the hinged rod 8 by bolts. A running idler frame 9 is fixed to the other end of the hinged rod 8. A running idler 10 is installed on the running idler frame 9. The running idler frame 9 is bow-shaped. The number of the running idlers 10 is set to two and they are respectively installed on the inner sides of the two ends of the running idler frame 9. The two running idlers 9 are in an eight-shape.

[0023] like Figure 1 As shown, it also includes a pull rod 11, one end of the pull rod 11 is hinged to the second cross beam 4, and the other end of the pull rod 11 is hinged to the deviation roller frame 9.

[0024] In this embodiment, a hinged rod 8 is provided, and the belt idler frame 5 and the deviation idler frame 9 are respectively arranged at the left and right ends of the hinged rod 8. When the belt deviates, the deviation idler frame 9 is driven to deviate. The idler frame 5 swings in the opposite direction due to the action of the hinged rod 8, continuously and automatically correcting the position of the belt on the idler 6, thereby realizing the automatic belt deviation prevention function. The function of the pull rod 11 is to limit the swing amplitude of the deviation idler frame 9 and improve the stability of the device.

[0025] When in use, fix the deviation roller frame 9 under the belt and do not let the deviation roller frame 9 contact the bottom of the friction belt. Example 2

[0026] Due to the vibration during belt transportation, when the belt is not deviating, the deviation roller frame 9 will rotate a certain angle due to the vibration of the belt, increasing the resistance of the belt transportation. Therefore, when the belt is not deviating, the deviation roller frame 9 needs to be fixed, and when the belt is deviating, the deviation roller frame 9 needs to be able to rotate.

[0027] The difference between Example 2 and Example 1 is that:

[0028] like Figures 2-3As shown, the pressure sensor 13 is arranged on the side of the running deviation roller 10 which is in contact with the belt, the number of the pressure sensor 13 is set to two and is arranged on the two running deviation rollers 10 respectively, the hinged seat 12 is an electromagnet, the lower end of the hinged rod 8 is fixed with the bolt shaft 14 which is hinged with the hinged seat 12, the bolt shaft 14 is a permanent magnet, the pressure sensor 13 is electrically connected with the electromagnet through the controller. When the hinged seat 12, i.e. the electromagnet, is powered, the hinged seat 12, i.e. the electromagnet, will attract the bolt shaft 14, i.e. the permanent magnet, when the hinged seat 12, i.e. the electromagnet, is powered off, the bolt shaft 14, i.e. the permanent magnet, can rotate relative to the hinged seat 12, i.e. the electromagnet.

[0029] In the initial state, the running deviation roller frame 9 is located in the middle of the two longitudinal beams, the pressure sensor 13 controls the electromagnet to be powered through the controller, and the hinged seat 12 attracts the bolt shaft 14. Avoiding the increase of the resistance of the stable conveying of the belt caused by the rotation of the running deviation roller frame 9 by a certain angle due to the vibration of the belt in the process of the deviation of the belt;

[0030] When the belt deviates, one of the pressure sensors 13 will be pressed, the pressed pressure sensor 13 makes the electromagnet powered off through the controller, and the bolt shaft 14 can rotate relative to the hinged seat 12, so that the running deviation roller frame 9 can rotate; allowing the belt to automatically correct.

[0031] When the belt is automatically corrected, the pressure sensor 13 is no longer pressed by the belt, at this time, the running deviation roller frame 9 is located in the middle of the two longitudinal beams again, the pressure sensor 13 makes the electromagnet powered again through the controller to attract the hinged bolt shaft 14.

[0032] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be limited by the protection scope of the claims.
