[0021] The utility model is further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Example 1

[0023] like Figure 1-4 As shown, the automatic deviation adjustment device of the belt conveyor disclosed by the utility model includes a deviation adjustment base 1 and a middle roller frame 2, the middle roller frame 2 is rotatably connected to the top of the deviation adjustment base 1, and a guide roller 10 is embedded in the middle roller frame 2. The middle roller frame 2 is vertically fixed with a side roller frame 7 near the two side edges, and the side roller frame 7 is rotatably connected with a guide roller group 8, and the guide roller group 8 is vertically arranged with the guide roller 10; a supporting rotating mechanism is provided between the bottom of both sides of the middle roller frame 2 and the deviation adjustment base 1.

[0024] The utility model aims at the technical problems that the deflection adjusting frame in the prior art does not take into account the deflection of the belt during operation, causing excessive load on one side of the deflection adjusting frame, making it easy to be damaged, and the accuracy of controlling the deflection angle is difficult to control. By arranging a middle roller frame 2, a guide roller 10 is arranged on the middle roller frame 2, and the belt is guided and conveyed; by arranging the middle roller frame 2 to be rotatable on the deflection adjusting base 1, the overall rotating conveying axis is deflected, and combined with the supporting rotating mechanism arranged between the bottom of both sides of the middle roller frame 2 and the deflection adjusting base 1, the rotational deflection adjustment of the overall device is realized, and the supporting performance of the middle roller frame 2 is improved.

[0025] Example 2

[0026] In this embodiment, a bearing 3 is embedded in the deviation adjustment base 1 , a rotating shaft 4 is rotatably connected in the bearing, and the end of the rotating shaft 4 extending out of the bearing 3 is connected to the bottom of the middle roller frame 2 .

[0027] The rotating shaft 4 is rotatably connected to the inner ring of the bearing 3. The upper end of the rotating shaft 4 is connected to the middle roller frame 2, and the lower end of the rotating shaft 4 is inserted into the inner ring of the bearing 3. In practical applications, the rotating shaft 4 can be made of 45# steel. The rotating shaft 4 cooperates with the bearing 3, rotates sensitively, is not easy to be damaged, and has good stability.

[0028] Furthermore, the longitudinal section of the middle roller frame 2 is an inverted trapezoidal structure. The middle roller frame 2 includes a middle plate and two side plates. The middle plate is horizontally arranged, and the two side plates are symmetrically inclined relative to the middle plate. The guide roller 10 is rotatably arranged on the middle plate and the two side plates.

[0029] In this embodiment, the middle roller frame 2 is set to be an inverted trapezoid. Firstly, it can prevent the belt from deviating from both sides. Secondly, the deviation can be adjusted by rotating the middle roller frame 2.

[0030] Furthermore, the supporting rotation mechanism includes mutually connected deviation adjustment pillars 5 and bottom balls 6, and the bottoms of the two side plates are fixedly connected to the deviation adjustment pillars 5; a slide groove 9 is provided on the deviation adjustment base 1, and the bottom ball 6 moves in the slide groove 9.

[0031] The utility model improves the strength of the deviation adjustment device by providing the deviation adjustment pillar 5 and the bottom ball 6, so that the main force points of the deviation adjustment device are concentrated on the deviation adjustment pillar 5 and the bottom ball 6, and the deviation adjustment angle can be controlled through the slide groove 9. Among them, when the slide groove 9 is designed, its center coincides with the axis of the rotating shaft 4, so that the angle of the rotation trajectory of the rotating shaft 4 and the bottom ball 6 is consistent.

[0032] Furthermore, the longitudinal section of the slide groove 9 is an arc-shaped structure, and the slide groove 9 abuts against the bottom ball 6 .

[0033] The bottom ball 6 is embedded in the slide groove 9 and the two are fitted together. This structure can not only realize that the bottom ball 6 rotates with the middle roller frame 2 and then moves in the slide groove 9, but also the slide groove 9 is evenly stressed and has good wrapping performance. The bottom ball 6 moves smoothly, and the load received by the middle roller frame 2 can be better transferred to the deviation adjustment base 1; and the slide groove 9 and the bottom ball 6 are in line contact, the resistance during movement is small, the movement is more flexible, and further the deviation can be accurately adjusted; the slide groove 9 can be manufactured separately and embedded in the deviation adjustment base 1, or it can be integrally formed with the deviation adjustment base 1 and milled directly on the deviation adjustment base 1. In order to ensure the smoothness of the bottom ball 6 and the slide groove 9 during movement, lubricating oil can be applied to the surface of the slide groove 9 and the bottom ball in the above two forms.

[0034] Example 3

[0035] On the basis of Example 2, the guide roller group 8 includes two guide rollers, the two guide rollers are parallel to each other, and the two guide rollers are perpendicularly arranged to the guide rollers 10 arranged on the side plate.

[0036] Different from the prior art, the two guide rollers of the utility model are arranged in parallel. Compared with the single guide roller in the prior art, the double guide roller structure of the utility model can be considered that its contact length with the tape is the distance between the center lines of the two guide rollers. Compared with the line contact of the single guide roller in the prior art, the tape can be adjusted through a longer contact length, and only the line contact friction of a guide roller is added on the original basis.

[0037] Furthermore, the guide roller is a tapered guide roller, and the outer diameter of the tapered guide roller gradually decreases from an end away from the guide roller 10 to an end close to the guide roller 10 .

[0038] Two parallel guide rollers are provided to play a guiding and limiting role, and the guide rollers are all provided in the form of conical guide rollers, which can actively prevent the tape from deviating upward when the tape deviates to the side roller frame 7. The conical guide rollers can provide a downward correction force to achieve further deviation adjustment.

[0039] The working principle of the utility model is:

[0040] During actual operation, the center line of the belt coincides with the center line of the middle roller frame 2. When the belt deviates, the center line of the belt deviates from the center line of the middle roller frame 2 and moves toward the side roller frame 7. At this time, the guide rollers on the side roller frame 7 will be subjected to force, further driving the rotating shaft 4 to rotate in the bearing 3. The rotating shaft 4 drives the middle roller frame 2 to rotate, further driving the bottom ball 6 to move in the slide groove 9. At this time, the guide rollers on the two side roller frames 7 will form an angle. Combined with the conical surface of the guide rollers, the belt is adjusted to move toward the original position.
