Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a large-load anti-sticking material conveying roller. Background Art

[0002] Materials are usually transported by belt conveyors. The power source of the belt conveyor is driven by a motor to drive the roller to carry the material back and forth. When the roller rotates, it drives the belt to rotate, thereby transporting the material. Due to various abnormal or sudden situations, material blockage often occurs. During transportation, the material may enter the gap between the roller and the belt and adhere to the outer wall of the roller. In this way, the outer circumference of the roller will change, that is, the contact surface between the roller and the belt will increase, which will cause the belt to slip, deviate, overload, or even tear when rotating, causing production interruption and very troublesome maintenance.

[0003] The anti-sticking conveyor roller disclosed in the publication number CN220097536U adopts a spiral structure to convey the materials falling into the inner side of the roller to the outer side of the roller. Its disadvantages are also obvious. The belt conveyor equipped with the conveyor roller can only meet the transmission of materials with a smaller load. If the load borne by the belt is too large, the outer wall of the conveyor roller will be subjected to a large force. Since there is a gap between the spiral structure and the inner wall of the roller, the support force of the entire roller is provided by the fixed plate, and the spiral structure does not provide support for the inner wall of the roller. Therefore, once the outer wall of the conveyor roller is subjected to too much force, the conveyor roller will be deformed, affecting the transmission of the belt. Utility Model Content

[0004] The utility model aims to solve the above problems and designs a large-load anti-sticking material conveying roller, which can prevent materials from adhering to the outer wall of the roller and provide support for the inner wall of the conveying roller to avoid affecting the movement of the belt.

[0005] The technical solution of the utility model to achieve the above-mentioned purpose is a large-load anti-sticking material conveying roller, comprising a conveying roller body, a plurality of feeding holes are opened on the outer wall of the conveying roller body along the circumferential direction, a rotating shaft is arranged on the inner side of the conveying roller body, the rotating shaft extends along the axial direction of the conveying roller body, and the two ends of the rotating shaft extend from the two ends of the conveying roller body;

[0006] At least three blades are arranged on the circumference of the rotating shaft, and the blades extend along the axial direction of the conveying roller body. At least three of the blades are fixedly connected to the inner wall of the conveying roller body on the side away from the rotating shaft, and divide the inner space of the conveying roller body into at least three leakage spaces. The feed hole is connected to the leakage space.

[0007] Preferably, at least one side of the blade is provided with an inclined surface, and the inclined surface is formed by obliquely extending from one end of the blade to the other end.

[0008] Preferably, at least one side of the blade is provided with two inclined surfaces, which extend obliquely from the middle of the blade to both ends to form the two inclined surfaces.

[0009] Preferably, the length of the blade does not exceed the axial length of the conveying roller body.

[0010] Preferably, each leakage space is communicated with at least one feed hole, and the feed hole extends along the axial direction of the conveying roller body.

[0011] Preferably, each leakage space is connected to two or more feed holes, wherein the two or more feed holes are distributed at equal intervals in the axial direction of the conveying roller body.

[0012] Preferably, the plurality of feed holes are distributed in a ring array in the circumferential direction of the conveying roller body.

[0013] Compared with the prior art, the beneficial effects are:

[0014] The utility model has the advantages of simple structure, strong practicality and large load. The blades respectively connected to the inner wall of the rotating shaft and the roller can support the inner wall of the conveying roller so that the conveying roller can bear a larger load. During the relative movement between the conveying roller and the belt, the conveying roller is not easily deformed due to excessive load. The material enters the inner side of the roller through the feed hole and is not easy to adhere to the outer wall of the roller. In this way, the size of the contact surface between the roller and the belt, that is, the outer circumference of the roller will not change, the roller can cooperate with the belt well, and the belt will not slip, deviate, be overloaded or even torn, thereby ensuring that the belt conveyor can work normally. At the same time, the material accumulated on the inner side of the roller can be naturally discharged from both ends of the roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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. Based on the embodiments of 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.

[0021] like Figure 1 and Figure 2 As shown, a preferred embodiment of the utility model proposes a large-load anti-sticking material conveying roller, which mainly includes a conveying roller body 1, and a rotating shaft 2 and blades 3 arranged inside the conveying roller body 1, wherein the two ends of the conveying roller body 1 are connected front and back, the rotating shaft 2 passes through the conveying roller body 1, and the two ends of the rotating shaft 2 extend from the two ends of the conveying roller body 1. One end of the rotating shaft 2 is generally rotatably connected to the bearing seat, and the other end is connected to the motor or gear. There are at least three blades 3, which are distributed in an annular array on the circumference of the rotating shaft 2, and one end of the blade 3 extends along the axial direction of the conveying roller body 1. The length of the blade 3 generally does not exceed the length of the conveying roller body 1.

[0022] refer to Figure 2 , Figure 3 The number of blades 3 must be at least 3, which plays a role of three-point support. In this embodiment, the number of blades 3 is 6. The more blades 3 there are, the stronger the support force is. One side of each blade 3 is fixedly connected to the rotating shaft 2, and the other side is fixedly connected to the inner wall of the conveying roller body 1, so that the inner space of the conveying roller body 1 is divided into multiple material leakage spaces 12. At the same time, multiple blades 3 can provide support for the inner wall of the conveying roller body 1. When the motor or gear drives the rotating shaft 2 to rotate, it will drive the conveying roller body 1 to rotate, thereby driving the belt to move.

[0023] refer to Figure 1 , Figure 4 A plurality of feed holes 11 are provided on the outer wall of the conveyor roller body 1. The plurality of feed holes 11 are distributed in a circular array, and each feed hole 11 is connected to a corresponding leakage space 12. The material adhered to the outer wall of the conveyor roller will enter the leakage space 12 inside the conveyor roller body 1 through the feed holes 11, thereby preventing the belt movement from being affected by the material adhered between the outer wall of the conveyor roller and the belt.

[0024] In this embodiment, several feed holes 11 are evenly distributed along the circumference of the conveyor roller body 1, and each leakage space 12 is connected to at least one feed hole 11. The feed hole 11 can extend along the axial direction of the conveyor roller, and the length of the feed hole 11 is slightly smaller than the length of the conveyor roller body 1. It is also possible to set multiple feed holes 11 in the axial direction of the conveyor roller body 1, and the multiple feed holes 11 are linearly and evenly spaced in the axial direction of the conveyor roller body 1 to ensure that the contact area between the feed hole 11 and the belt is as large as possible, and the material can enter the leakage space 12 through the feed hole 11 as much as possible.

[0025] The shape of the feed hole 11 is not limited, and can be square, oblong, or other shapes.

[0026] At least one side of each blade 3 is provided with an inclined surface 31, preferably both sides are provided with an inclined surface 31. After the material enters the leakage space 12, as the blade 3 rotates, the excess material will leak out from the end of the conveying roller body 1 along the inclined surface 31 of the blade 3.

[0027] If only one inclined surface 31 is provided on each side of the blade 3, the inclined surface 31 can extend obliquely from one end of the blade 3 to the other end, and the material can leak out from one end of the conveying roller along the inclined surface 31. Alternatively, two inclined surfaces 31 with opposite inclination directions can be provided on each side, and the two inclined surfaces 31 are symmetrically distributed and extend obliquely from the middle of the blade 3 to both ends, so that the material can leak out from both ends of the conveying roller body 1 along the inclined surface 31.

[0028] In other technical solutions, the inclined surface 31 may not be provided, and if too much material accumulates in the leakage space 12, it will naturally leak out from both ends of the conveying roller body 1. The inclined surface 31 is provided to guide the material to leak out from both ends of the conveying roller body 1.

[0029] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the utility model and fall within the protection scope of the utility model.
