Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a conveyor deviation correction device. Background Art

[0002] Belt conveyors are a type of conveying equipment that is widely used in the field of material transportation. Their safe and stable operation directly affects production operations. Therefore, they are generally equipped with deviation correction devices. The patent with application number 202010199909.X discloses a dynamically adjustable six-link deviation correction device for the bearing surface and return surface of a conveyor, wherein rollers 1, 2, and 4 are installed on a rotating frame, and the rotating shaft 1 is centered at the lower part of the rotating frame 1, penetrates into the bearing group 1, and is connected to the bottom support beam 1. Connecting rods 1, 2, and 3 are connected end to end, wherein connecting rod 1 is connected to the rotating frame, connecting rod 2 is connected to the measuring roller mounting seat 1, and connecting rod 3 is connected to the detection roller 1 and is installed on the conveyor frame, and the detection roller 1 is located on one side of the conveyor belt; connecting rods 4, 5, and 6 are connected end to end, wherein connecting rod 4 is connected to the rotating frame 1, and connecting rod 5 is connected to the measuring roller mounting seat 1. The detection roller 2 is located on the other side of the conveyor belt and has the advantage of not requiring power. However, when the belt deviates, it pushes the detection roller on the left to move outward (which will drive the rotating frame to rotate for deviation correction), and the detection roller on the right is also driven to move to the left. This causes the belt to move to the right when the rotating frame rotates for deviation correction. When the belt touches the detection roller on the right to the right, the detection roller on the right is not in its original position but to the left of its original position. At this time, it is easy to cause the detection roller on the right to push the rotating frame to rotate back, and the belt deviates to the left again. It takes several times to make the belt run completely in the center. Utility Model Content

DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0014] Specific implementation method: Combination Figure 1-3As shown, a conveyor deviation correction device includes a bottom supporting beam 1 and a rotating frame 5, and the two are rotatably connected. A rotating shaft can be set at the center of the bottom surface of the rotating frame 5, and a shaft cylinder is set at the center of the top surface of the bottom supporting beam 1. The rotating shaft and the shaft cylinder are rotatably connected. A roller group is set on the rotating frame 5 to support the bottom surface of the belt. Two blocking arms 11 are symmetrically arranged on one side of the bottom supporting beam 1 about its symmetry plane. A third rotating shaft 51 is arranged on both sides of the bottom of the rotating frame 5. The third rotating shaft 51 is located in the long hole on the connecting plate 3. The third rotating shaft 51 can rotate relative to the long hole and can slide along the long hole. It also includes a rotating arm 2. The rotating arm 2 includes a first flat arm 22, a second flat arm 23 is provided at one end of the first flat arm 22, and an inclined arm 21 is provided at the other end. A vertical blocking roller 211 is provided on the inclined arm 21. The first flat arm 22 is rotatably connected to the blocking arm 11, and the second flat arm 23 is rotatably connected to the connecting plate 3. A pulling plate 212 located on the outside of the blocking arm 11 is provided at the lower end of the inclined arm 21, and a tension spring 4 is provided between the pulling plate 212 and the blocking arm 11. The spring 4 can make the pulling plate 212 stick to the outside of the blocking arm 11. At this time, the third rotating shaft 51 is located at the end of the long hole away from the second flat arm 23. When in use, the belt runs from the direction of the rotating frame 5 to the direction of the vertical stop roller 211. When the belt deviates to the left, the edge of the belt contacts the vertical stop roller 211 on the left to push the rotating frame 5 to rotate for correction. At this time, the third rotating shaft 51 on the right will slide relative to the long hole and push the connecting plate 3 to rotate, but due to the action of the spring 4, the rotating arm 2 on the right remains stationary, so that the vertical stop roller 211 on the right remains stationary. At this time, two situations will occur: the first is that the belt just runs in the center (within a range, within which the belt will not touch the two vertical stop rollers 211). At this time, under the action of the spring 4, the vertical stop roller 211 on the left returns to its original position, and the correction is completed. It can be seen that since the vertical stop roller 211 that is not in contact with the belt will not move due to the rotation of the rotating frame 5 but remains in place, when the belt just runs in the center, the correction only needs one time, and the efficiency is relatively high; the second is that the belt deviates to the right and touches the vertical stop roller 211 on the right. At this time, the rotating frame 5 rotates to the left for correction. After repeated several times, the belt runs in the center. The working principle when the belt deviates to the right is the same as above.

[0015] Specifically, a first rotating shaft 111 is disposed on the upper side of the barrier arm 11 , and an end of the first flat arm 22 close to the second flat arm 23 is provided with an axial hole rotatably connected to the first rotating shaft 111 to achieve rotatable connection between the first flat arm 22 and the barrier arm 11 .

[0016] Specifically, a second rotating shaft 231 is disposed at one end of the second flat arm 23 away from the first flat arm 22 , and a through hole rotatably connected to the second rotating shaft 231 is disposed on the connecting plate 3 to achieve the rotatable connection between the second flat arm 23 and the connecting plate 3 .

[0017] Specifically, a convex plate protruding from the bottom surface of the barrier arm 11 is provided on one side of the barrier arm 11 away from the pull plate 212 , the lower end of the pull plate 212 protrudes from the bottom surface of the barrier arm 11 , and the spring 4 is arranged between the convex plate and the pull plate 212 .

[0018] The above embodiments are merely descriptions of preferred implementation schemes of the present invention, and are not intended to limit the protection scope of the present invention. Without departing from the design spirit of the present invention, any modification and improvement of the technical solution of the present invention made by a person of ordinary skill in the art shall fall within the protection scope of the present invention.
