Description

Technical Field

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

[0002] As we all know, the role of rollers is to support the weight of conveyor belts and materials. The operation of rollers must be flexible and reliable. Reducing the friction between the conveyor belt and the rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although rollers are a relatively small component in belt conveyors and their structure is not complicated, they play an extremely important role.

[0003] At present, the traditional roller is fixedly installed on the frame of the belt conveyor, and its main purpose is to indicate the weight of the material. However, it is found in practice that during the operation of the belt conveyor, the belt is offset due to different forces on the belt, and the belt often deviates. At this time, it is necessary to adjust the installation angle of the roller in time to correct the deviation of the belt. Since both ends of the roller are fixedly connected in traditional technology, the adjustment process is relatively cumbersome. Therefore, it is of great significance to design and develop a device that can quickly and conveniently adjust the angle of the roller. Utility Model Content

[0004] The utility model aims to solve the technical problems existing in the known technology and provides a return belt deviation adjustment device for a belt conveyor, which can quickly and conveniently adjust the angle of the roller and thus solve the technical problem of belt deviation.

[0005] The utility model aims to provide a belt conveyor return belt deviation adjustment device, comprising a roller and a belt conveyor frame located at both ends of the roller; an extension shaft is provided at one end of the roller. A lap shaft is provided at the other end of the roller, and the left end of the extension shaft is hinged to a fixed bracket, and the fixed bracket is installed on the left side of the belt conveyor frame; an adjustment bracket is installed on the right side of the belt conveyor frame, and a plurality of slots are opened on the upper surface of the adjustment bracket, and the outer diameter of the lap shaft is smaller than the width of the slot, and the lap shaft is overlapped in the slot.

[0006] Preferably, the slot is a rectangular slot or a U-shaped slot.

[0007] Preferably, the central axis, the extension axis and the lap axis of the roller are an integrally formed structure.

[0008] Preferably, the outer diameter of the roller is larger than the outer diameters of the extension shaft and the overlap shaft.

[0009] Preferably, the length of the overlap shaft is 150 mm.

[0010] Preferably, an anti-wear layer is provided in the card slot.

[0011] Preferably, the anti-wear layer is made of ceramic material.

[0012] The advantages and positive effects of the utility model are:

[0013] The utility model can quickly and conveniently adjust the angle of the roller, thereby solving the technical problem of belt deviation; the specific adjustment method is: according to the degree of belt deviation, determine the angle of the roller that needs to be adjusted, when the angle is determined, select a suitable target slot, and finally, lift one end of the lap shaft and place the other end of the lap shaft into the target slot.

[0018] In order to make the above-mentioned purpose, design control system and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] like Figures 1 to 3 As shown, the technical solution of the utility model is:

[0020] A return belt deviation adjustment device for a belt conveyor, comprising:

[0021] Roller 1; one end of the roller 1 is provided with an extension shaft. The other end of the roller 1 is provided with a lap shaft 1-1, the length of which is determined according to the actual width of the belt conveyor. In this embodiment, the length of the lap shaft 1-1 is 150 mm;

[0022] A belt conveyor frame 4 is located at both ends of the roller 1; the left end of the extended shaft is hinged to the fixed bracket 3, and the fixed bracket 3 is installed on the belt conveyor frame on the left; an adjusting bracket 2 is installed on the belt conveyor frame on the right, and a plurality of slots 2-1 are opened on the upper surface of the adjusting bracket 2, the outer diameter of the lap shaft 1-1 is smaller than the width of the slot 2-1, and the lap shaft 1-1 is overlapped in the slot 2-1.

[0023] In order to facilitate processing, the slot 2 - 1 is a rectangular slot or a U-shaped slot.

[0024] In order to improve the structural strength of the workpiece, the central axis, the extended axis and the lap axis 1-1 of the roller 1 are an integrally formed structure.

[0025] The outer diameter of the roller 1 is larger than the outer diameters of the extension shaft and the overlap shaft 1 - 1 .

[0026] In order to increase the service life of the device, an anti-wear layer is provided in the card slot 2-1. The anti-wear layer can be made of ceramic material.

[0027] The working principle of this preferred embodiment is:

[0028] During the operation of the belt conveyor, the return belt moves on the roller. When the return belt deviates, the staff will determine the need to adjust the inclination angle of the roller (that is, the angle between the roller and the running direction of the belt) based on the degree of belt deviation. Once the inclination angle is determined, the appropriate target slot can be selected. Finally, lift one end of the lap shaft and place it into the target slot. During operation, the roller rotates with the belt, and axial friction is generated through operation to return the belt to the correct position.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
