[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] Detailed Implementation: As shown in Figures 1-3, an electric alignment device includes a frame 1 of a belt conveyor and a self-aligning idler 2. The self-aligning idler 2 is rotatably connected to a crossbeam 22, and both ends of the crossbeam 22 are connected to the frame 1. A side arm 21 is provided at the lower part of the self-aligning idler 2. The self-aligning idler 2 includes a rotating frame and three idlers disposed thereon. The side arm 21 is disposed on the rotating frame and is hinged to the piston rod end of an electric push rod 3. The bottom end of the electric push rod 3 is hinged to the crossbeam 22 or the frame 1. The electric push rod 3 can push the self-aligning idler 2 to rotate for alignment. Support seats 6 are provided on both sides of the frame 1 in the width direction of the belt conveyor. The support seats 6 are located on one side of the self-aligning idler 2 in the length direction of the belt conveyor. A deviation switch 5 is provided on the support seat 6. A controller 4 is provided on one side of the frame 1. The electric push rod 3 and the deviation switch 5 are electrically connected to the controller 4.

[0017] Furthermore, the belt misalignment switch 5 includes a housing 51, within which a cavity 511 is provided. A pressure sensor 52 is disposed on one side of the cavity 511 and electrically connected to the controller 4. A slider 54 is also slidably connected to the housing 51. The portion of the cavity 511 and the slider 54 that is slidably connected has an inverted T-shaped cross-section that extends through the upper surface of the housing 51. Sliding grooves are provided on both sides of the slider 54 to allow it to slide and connect with the upper part of the inverted T-shaped cavity 511. The slider 54 penetrates the housing 51 and extends into the cavity 511. A spring 53 is disposed between the slider 54 and the pressure sensor 52. A vertical roller 541 is rotatably connected to the slider 54. When the belt misalignment pushes the vertical roller 541 and the slider 54 to move, the spring 53 is compressed. The controller 4 can calculate the displacement of the slider 54 based on the pressure obtained by the pressure sensor 52 (the difference between the measured pressure and the initial pressure divided by the spring constant k). Compared with the traditional deflection roller type belt misalignment switch, the belt misalignment switch of this application does not deflect the roller 541. This is because after the roller 541 deflects, the belt moves outward (towards the upper end of the roller 541) in the axial direction of the roller 541. As the roller 541 deflects, the deflection angle of the roller 541 increases by the same amount of belt misalignment, resulting in inaccurate measurement of the amount of misalignment. However, since the roller 541 of this application does not deflect, this problem does not exist.

[0018] Furthermore, the support base 6 includes a base 61, on which a column 62 is provided, and at the upper end of the column 62 is a mounting base 63. The tilt angle of the mounting base 63 is the same as the tilt angle of the rollers on both sides of the self-aligning roller 2, and the deviation switch 5 is mounted on the mounting base 63.

[0019] Furthermore, the vertical roller 541 is perpendicular to the plane where the mounting base 63 is located.

[0020] Furthermore, as shown in Figure 1, the base 61 has elongated holes on both sides and also includes a clamping plate located below the frame 1. Bolts pass through the elongated holes and through holes on the clamping plate and are connected to nuts, thereby allowing the position of the support base 6 to be adjusted in the left and right directions.

[0021] Furthermore, as shown in Figure 1, the mounting base 63 has elongated holes on both sides, and the deviation switch 5 has ear plates on both sides with through holes. The bolts pass through the through holes and elongated holes and are connected to the nuts. By adjusting the position of the support base 6, the position of the deviation switch 5 in the vertical and horizontal directions can be adjusted, so that the vertical roller 541 is in a suitable position.

[0022] When the belt deviates from its designated path during use, it will contact the belt deviation switch 5 on one side. The controller 4 can determine the belt deviation value based on the signal from the belt deviation switch 5, and then control the electric push rod 3 to push the self-aligning idler 2 to rotate at the corresponding angle, so that the belt returns to normal.
