[0002] The belt conveyor deviation correction device is an important part of the belt conveyor. At present, there are many kinds of deviation correction devices with different structures, which can solve the belt deviation problems to a greater or lesser extent in use. However, it is difficult to achieve a good effect in some places where the belt deviation is serious or the belt speed is high, because all the deviation correction devices correct the belt deviation by using the friction between the belt and the roller on the deviation correction device and changing the direction of the friction force. The magnitude of the friction force depends on the friction coefficient between the roller and the belt and the magnitude of the positive pressure between the belt and the roller.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example

[0035] See also Figure 1-5 The present embodiment provides the following technical solutions: a return flat roller type automatic deviation correction system, comprising a roller shaft 1 and a swing angle roller 2 arranged on the roller shaft 1, end brackets 3 are arranged at both ends of the roller shaft 1, and the end brackets 3 are connected to the roller shaft 1 through a lifting and adjusting mechanism for adjusting the height of the roller shaft 1. The adjustment mechanism overcomes the space limitation problem encountered when adjusting the height of the swing angle roller 2, which is beneficial for the staff to adjust the height of the swing angle roller 2, and the operation is more time-saving and labor-saving, thereby increasing the efficiency of the normal use of the swing angle roller 2.

[0036] The adjusting mechanism includes a lifting groove 4, which is arranged on the end bracket 3, and a shaft plate 5 is slidably connected to the lifting groove 4, and a hole groove for the roller shaft 1 to pass through is arranged on the shaft plate 5; a fixing frame 6 fixedly arranged on the end bracket 3, and an adjusting groove 7 is arranged on the fixing frame 6; a lifting frame 8 fixedly arranged on the shaft plate 5, and the lifting frame 8 is slidably connected to the adjusting groove 7; a driving component 9 arranged on the fixing frame 6, which is used to drive the lifting frame 8 to move on the fixing frame 6, and through the driving component 9, the lifting frame 8 drives the shaft plate 5 to move upward or downward along the adjusting groove 7 on the fixing frame 6, so that the height of the swing angle roller 2 is adjusted by adjusting the height of the peripheral shaft plate 5.

[0037] In some embodiments, a sliding sleeve is fixedly connected to the side of the shaft plate 5 that is opposite to the swing angle roller 2. The sliding sleeve is movably connected to the roller shaft 1. A sixth locking bolt is threadedly connected to the sliding sleeve. The roller shaft 1 can be locked and fixed on the sliding sleeve and the shaft plate 5 through the sixth locking bolt. Therefore, the position of the shaft plate 5 and the end bracket 3 on the roller shaft 1 can be adjusted according to the working environment of the swing angle roller 2, thereby changing the distance between the end brackets 3 at both ends.

[0038] In some embodiments, the end bracket 3 is an inverted "L"-shaped structure.

[0039] In some embodiments, the shaft plate 5 is an "I"-shaped structure, and the end bracket 3 is located between the two sides of the shaft plate 5, which further increases the stability of the shaft plate 5 on the end bracket 3, thereby improving the smoothness of the rotation of the swing angle roller 2 on the end bracket 3.

[0040] The outer roller of the swing angle roller 2 includes a center roller 21 and an edge roller 22. The edge rollers 22 are fixedly arranged at both ends of the center roller 21. The center roller 21 is a cylindrical structure, and the edge roller 22 is a conical structure. The diameter of the outer end of the edge roller 22 is smaller than the diameter of the inner end of the edge roller 22. When the belt begins to deviate from the center, the force applied to it in contact with the conical surfaces at both ends of the swing angle roller 2 will change, causing the swing angle roller 2 to swing forward and rotate, thereby turning the belt back to the center, which can ensure that the belt always finds a balance between the forces on the taper.

[0041] A groove 23 is provided on the outer surface of the edge roller 22. The groove 23 can increase the friction between the edge roller 22 and the belt, which is more conducive to the deviation correction operation of the belt.

[0042] The top end of the end bracket 3 is arranged on the conveying equipment through a first locking bolt, and the first locking bolt facilitates the disassembly and assembly of the end bracket 3.

[0043] The fixing frame 6 is a "U"-shaped structure, and connecting plates 10 are fixedly provided at both ends of the fixing frame 6. The connecting plates 10 are fixed to the end bracket 3 by second locking bolts. The second locking bolts facilitate the disassembly and assembly of the fixing frame 6.

[0044] The lifting frame 8 includes a transverse plate 81, which is located in the adjustment groove 7 and is slidably connected to the adjustment groove 7; a side plate 82 is fixedly arranged at the end of the transverse plate 81, and the two side plates 82 are respectively located on the outer sides of the left and right side walls of the fixing frame 6 and are slidably connected to the side walls of the fixing frame 6, and the ends of the side plates 82 are fixedly connected to the shaft plate 5 through connecting pieces. In some embodiments, the transverse plate 81 and the two side plates 82 together form a "U"-shaped structure. Through the transverse plate 81 and the side plates 82, the lifting frame 8 can be better enabled to perform limited sliding on the fixing frame 6.

[0045] The connecting part includes a first fixing plate 83, one end of which is fixed to the shaft plate 5 by a third locking bolt; a second fixing plate 84, one end of which is fixed to the side plate 82 by a fourth locking bolt, and the second fixing plate 84 is fixedly connected to the other end of the first fixing plate 83 by a fifth locking bolt. The first fixing plate 83 and the second fixing plate 84 can be disassembled and assembled by the third locking bolt, the fourth locking bolt and the fifth locking bolt.

[0046] In some implementations, the first fixing plate 83 and the second fixing plate 84 are both “L” shaped structures.

[0047] The driving assembly 9 includes a screw 91, which is rotatably connected to the fixed frame 6; a nut 92, which is fixedly set at one end of the screw 91; a rotating plate 93, which is rotatably connected to the other end of the screw 91, and the rotating plate 93 is fixedly connected to the connecting plate 10; a threaded hole, which is set on the cross plate 81 and is adapted to the screw 91. In some embodiments, the nut 92 is set at the lower end of the screw 91, and the rotating plate 93 is set at the top end of the screw 91. Through the nut 92, the screw 91 can be rotated to make the lifting frame 8 reciprocate upward or downward on the fixed frame 6 to complete the adjustment of the height of the swing angle roller 2.

[0048] The working principle of the utility model is as follows: when the height of the swing angle roller 2 needs to be adjusted, it is only necessary to rotate the nut 92 to make the screw rod 91 rotate forward or reversely, which can drive the lifting frame 8 to move upward or downward along the adjustment groove 7, thereby driving the roller shaft 1 to move upward or downward along the lifting groove 4 through the shaft plate 5 to adjust the height of the swing angle roller 2.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
