The specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] like Figure 1As shown, this embodiment exemplarily shows a tubular belt conveyor transition section variable groove angle correction roller group, including an upper crossbeam 2 and a lower crossbeam 1 installed on the belt conveyor frame, an intermediate roller frame 8 is fixed in the middle of the upper crossbeam 2, an intermediate roller 9 is rotatably installed in the intermediate roller frame 8, side rollers 11 are rotatably installed on both sides of the intermediate roller 9 through side roller frames 10, and a conveyor belt 15 is arranged between the side rollers 11 and the intermediate rollers 9; a rotating shaft 3 is fixed at the center of the lower end surface of the upper crossbeam 2, and the rotating shaft 3 is rotatably installed at the center of the upper end surface of the lower crossbeam 1. Specifically, a bearing 4 is installed at the center of the lower crossbeam 1, and the rotating shaft 3 is axially fixed in the inner ring of the bearing 4. The end of the rotating shaft 3 passes through the lower end surface of the lower crossbeam 1 and is provided with a first locking nut 5. The first locking nut 5 is used to adjust the rotation angle of the upper crossbeam 2 and then position it; the lower end surfaces of both ends of the upper crossbeam 2 are provided with rollers 7 , the upper end surfaces of both ends of the lower beam 1 directly below the roller 7 are provided with limiting slides 6, and when the upper beam 2 rotates around the rotating shaft 3, the roller 7 makes an arc motion on the limiting slide 6; one end of the side roller frame 10 is hinged with one end of the middle roller frame 8, and the other end is fixed with a first arc plate 14, and the upper end surfaces of both ends of the upper beam 2 are respectively fixed with second arc plates 12 matching the first arc plate 14, and the second arc plate 12 is provided with a first locking bolt 13 for positioning the first arc plate 14. The first arc plate 14 and the second arc plate 12 can adjust the groove angle of the transition section of the conveyor conveniently and quickly, and then use the first locking bolt 13 to quickly position them; a U-shaped frame 16 is fixed on one side of the upper beam 2, and two inclined rollers 17 are provided on the top of the U-shaped frame 16, and the ends of the rollers 17 face the conveyor belt 15 and the outer walls of the rollers 17 are in contact with the inner wall or outer wall of the conveyor belt 15.

[0014] like Figure 2 As shown, the limiting slide 6 is a U-shaped steel plate, and the two ends of the length of the U-shaped steel plate are limiting ends. The width of the U-shaped steel plate is determined according to the maximum angle that the upper crossbeam 2 can rotate to ensure that the roller 7 always rolls in the U-shaped steel plate during the rotation of the upper crossbeam 2 around the rotating shaft 3 and will not fall off.

[0015] See also Figure 1 and Figure 2In this embodiment, two rollers 17 are symmetrically arranged at the top of the U-shaped frame 16; specifically, the top of the rotating shaft of the roller 17 is installed on the U-shaped frame 16 through a slide 18, and the upper part of the slide 18 is slidably sleeved on the U-shaped frame 16. The rear end of the slide 18 is provided with a second locking bolt (not shown in the figure) for fixing the slide 18 on the U-shaped frame 16. The position of the roller 17 can be adjusted by moving the slide 18. After the adjustment is in place, the slide 18 can be positioned by using the second locking bolt. An arc-shaped through hole 21 is provided at the lower portion of the slide 18, and a third locking bolt 19 is vertically connected to the top end of the rotating shaft of the roller 17. The end of the third locking bolt 19 passes through the arc-shaped through hole 21 and is connected to the second locking nut 20. After the angle of the side roller 11 of the belt conveyor is adjusted, the roller 17 can be rotated to allow the third locking bolt 19 to rotate in the arc-shaped through hole 21 so that the roller 17 fits against the inner wall or outer wall of the conveyor belt 15, and then it can be fixed with the second locking nut 20.

[0016] like Figure 3 As shown, taking increasing the groove angle of the transition section of the conveyor (i.e., the conveyor belt of the tubular belt conveyor from a circular position to an unfolded position) as an example, first loosen the first locking bolt 13, rotate the two side rollers 11 outward by a certain angle, and use the first locking bolt 13 to position them after adjusting the angles of the two side rollers 11, rotate the roller 17 so that the third locking bolt 19 rotates in the arc-shaped through hole 21 so that the roller 17 fits the inner wall of the conveyor belt 15, and then fix it with the second locking nut 20 to facilitate better unfolding of the conveyor belt 15 and achieve a smooth transition of the belt; in addition, if the conveyor belt of the transition section of the tubular belt conveyor deviates, first loosen the first locking nut 5, and then rotate the entire upper crossbeam 2 around the rotating shaft 3 by a certain angle, and finally lock it with the first locking nut 5 to ensure that the side rollers on both sides fit the conveyor belt, so as to increase the length of the adjustment section and effectively correct the deviation.
