[0001] The utility model relates to the technical field of belt conveyors, and particularly relates to a quick-disassembly device for a belt conveyor. Background Art

[0002] Belt conveyors have the advantages of large conveying capacity, simple structure, convenient maintenance, standardized components, etc., and are used to convey loose materials or finished items. The commonly used belt conveyors in the current market (such as the belt conveyor quick-disassembly device of CN218930667U) drive the link mechanism through a handle to finally realize the tensioning or loosening of the conveyor belt. However, it is rather difficult for people to drive the link mechanism during operation, which increases unnecessary labor intensity, and it is also not easy to achieve the overall quick disassembly and assembly of the belt conveyor. Therefore, there is an urgent need for a quick-disassembly device for a belt conveyor to solve the above problems. Summary of the Utility Model

[0003] In order to solve the technical problems that the conveyor belt of the existing belt conveyor is not easy to be tensioned or loosened, and the quick-disassembly device is not easy to be quickly disassembled and assembled, the utility model provides a quick-disassembly device for a belt conveyor. The tensioning or relaxation of the conveyor belt can be easily adjusted. At the same time, the quick-disassembly device, the conveyor belt and the driven shaft can be quickly disassembled and assembled on the belt conveyor, fundamentally reducing the manual labor intensity and also reducing the time for disassembling and assembling the conveyor belt of the belt conveyor and cleaning the equipment.

[0004] The utility model provides a quick-disassembly device for a belt conveyor. The belt conveyor includes a frame, a driving shaft and a driven shaft rotatably arranged on the frame. A conveyor belt is wound between the driving shaft and the driven shaft. The quick-disassembly device includes a first mounting frame and a second mounting frame. One end of the first mounting frame is arranged on the frame, and the other end is rotatably connected to the second mounting frame. The first mounting frame and the second mounting frame are located on one side of the frame far from the driving shaft. The driven shaft is rotatably connected to the second mounting frame.

[0005] Further, the first mounting frame includes two first mounting plates oppositely arranged at the end of the frame through a first reinforcing plate. The second mounting frame includes two second mounting plates. Both of the two second mounting plates are rotatably connected to the first reinforcing plate. Removable connectors are arranged on the outer sides of the two second mounting plates, and the two ends of the driven shaft are respectively rotatably connected to the two connectors. The two second mounting plates can rotate relative to the first reinforcing plate.

[0006] Further, the first reinforcing plate is disposed between two first mounting plates. Fixing plates are provided at both ends of the first reinforcing plate. Through holes are provided on the opposite end faces of the two fixing plates. Notches are provided at one ends of the two first mounting plates, and the two notches respectively correspond to the two fixing plates. Protruding heads are provided at positions corresponding to the notches on one ends of the two second mounting plates. The protruding heads are located at the notches. Fixing shafts are provided on the protruding heads. The ends of the fixing shafts pass through the through holes and the fixing shafts rotate in the through holes. The ends of the fixing shafts are limited by first nuts. The setting of the first reinforcing plate further enhances the structural strength between the two first mounting plates. And the first reinforcing plate is fixedly connected to the frame, so as to fix the two first mounting plates on the frame. When the second mounting bracket needs to rotate, the first nut is removed, and the fixing shaft rotates in the through hole. When the second mounting bracket needs to be fixed, the end of the fixing shaft is defined on the fixing plate by the first nut.

[0007] Further, the first reinforcing plate is fixedly connected to the frame; two second reinforcing plates are further provided on the two first mounting plates.

[0008] Further, each connecting member includes a connecting rod and a bearing sleeve provided on the connecting rod. Fixing sleeves are provided on the outer side surfaces of each of the second mounting plates. One end of the connecting rod away from the bearing sleeve passes through the fixing sleeve and is fixed to the fixing sleeve by a second nut. Both ends of the driven shaft are rotatably connected to the two bearing sleeves respectively. When the driven shaft needs to be installed, the connecting rod is first fixed to the fixing sleeve by the second nut, and then both ends of the driven shaft are respectively rotatably connected to the bearing sleeves on the two connecting rods.

[0023] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0024] As Figures 1 to 5As shown in the figure, a quick-release device for a belt conveyor, the belt conveyor includes a frame and a driving shaft 4 and a driven shaft 5 rotatably arranged on the frame. A conveyor belt 6 is wound around between the driving shaft 4 and the driven shaft 5. The quick-release device includes a first mounting bracket 1 and a second mounting bracket 2. One end of the first mounting bracket 1 is arranged on the frame, and the other end is rotatably connected to the second mounting bracket 2. The first mounting bracket 1 and the second mounting bracket 2 are located on one side of the frame away from the driving shaft 4, and the driven shaft 5 is rotatably connected to the second mounting bracket 2.

[0025] In this embodiment, the first mounting bracket 1 and the second mounting bracket 2 are mounted on the frame. The second mounting bracket 2 realizes the mounting of the driven shaft 5 on the frame, and the conveyor belt 6 is sleeved on the driving shaft 4 and the driven shaft 5. When the driving shaft 4 rotates, it drives the driven shaft 5 and the conveyor belt 6 to rotate, and the conveyor belt 6 rotates to perform the conveying operation. When the driven shaft 5 rotates with the conveyor belt 6, the driven shaft 5, the first mounting bracket 1 and the second mounting bracket 2 are parallel, and the first mounting bracket 1 and the second mounting bracket 2 do not rotate relative to each other.

[0026] When the second mounting bracket 2 rotates counterclockwise, it will drive the driven shaft 5 to rotate counterclockwise. The position of the driven shaft 5 changes, and the driven shaft 5 moves upward relative to the first mounting bracket 1. The driven shaft 5 is in an inclined state, and at this time the conveyor belt 6 is in a slack state. When the driven shaft 5 and the second mounting bracket 2 are perpendicular to the first mounting bracket 1, the second mounting bracket 2 and the driven shaft 5 no longer rotate counterclockwise. When the conveyor belt 6 is in a slack state, the conveyor belt 6 can be quickly disassembled and assembled. When the second mounting bracket 2 rotates clockwise, it drives the driven shaft 5 to rotate clockwise and returns to the state where the driven shaft 5, the first mounting bracket 1 and the second mounting bracket 2 are parallel. At this time, the conveyor belt 6 is in a tensioned state, and the conveyor belt 6 waits for the next conveying operation.

[0027] The structure of the quick-release device in this embodiment is simple. The tension or slack of the conveyor belt 6 can be easily adjusted. At the same time, the quick-release device, the conveyor belt 6 and the driven shaft 5 can be quickly disassembled and assembled on the belt conveyor, fundamentally reducing the manual labor intensity and also reducing the time for disassembling and assembling the conveyor belt 6 and cleaning the equipment of the belt conveyor.

A fixing shaft 22 is provided on the protruding head. The end of the fixing shaft 22 passes through the through hole and the fixing shaft 22 rotates in the through hole. The end of the fixing shaft 22 is limited by a first nut. The setting of the first reinforcing plate 12 further enhances the structural strength between the two first mounting plates 11. When the second mounting bracket 2 needs to rotate, the first nut is removed, and the fixing shaft 22 rotates in the through hole. When the second mounting bracket 2 needs to be fixed, the end of the fixing shaft 22 is limited on the fixing plate 13 by the first nut.
