[0020] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative labor are within the scope of protection of the present utility model.

[0021] Please refer to Figs. 1-4 The utility model embodiment provides a kind of shaft for preventing deviation of conveying belt, it include: installation axle stand 1, the inner side of installation axle stand 1 is equipped with conveying shaft 2, the surface of conveying shaft 2 is provided with one convex node 3, and the left side of one convex node 3 is integrally connected with one slope 4, the left side of one slope 4 is integrally connected with two concave nodes 5, the left side of two concave nodes 5 is integrally connected with three slopes 6, the left side of three slopes 6 is integrally connected with two convex nodes 7, one convex node 3, one slope 4, two concave nodes 5, three slopes 6 and two convex nodes 7 are integrally connected, one slope 4, two concave nodes 5, three slopes 6 and two convex nodes 7 are sequentially distributed in the left side of one convex node 3, and the corresponding slope, concave node and convex node are also set in the position of mutual symmetry about the center line of one convex node 3, one slope 4, two concave nodes 5, three slopes 6 and two convex nodes 7, and the corresponding slope, concave node and convex node set in the position of left-right symmetry about the center line of one convex node 3, each section is set one by one, one slope 4 and three slopes about the symmetry center line of two concave nodes 5 are symmetric;

[0022] Specifically, the surface of the conveying shaft 2 is provided with a first protrusion 3, a first slope 4, a second recess 5, a third slope 6 and a second protrusion 7, which are processed by adjusting the cutting depth and the cutting position of the cutting tool when the shaft body of the conveying shaft 2 is processed. Due to the different cutting positions and depths, the surface of the conveying shaft 2 is uneven, and the curved surface of the conveying shaft 2 is processed into a specific position, a specific width, an uneven, symmetrical and regular shape relative to the center line of the width of the conveying belt. The corresponding slopes, recesses and protrusions, such as the first protrusion 3, the first slope 4, the second recess 5, the third slope 6 and the second protrusion 7, are sequentially distributed on both sides of the center line of the width of the conveying belt, and the first protrusion 3 is the center of symmetry, and the left and right of the first slope 4, the second recess 5, the third slope 6 and the second protrusion 7 are symmetrical. In this way, the first protrusion 3, the first slope 4, the second recess 5, the third slope 6 and the second protrusion 7 are regularly distributed on the surface of the conveying shaft 2, and each section of the first protrusion 3, the first slope 4, the second recess 5, the third slope 6 and the second protrusion 7 on the surface of the conveying shaft 2 is correspondingly arranged. This shape can force the conveying belt to deform slightly along the center line of the shaft in a certain section or multiple sections when the conveying belt is under stress. The deformed conveying belt is always pulled by a certain section under a large tension in operation, and this tension can weaken or even eliminate the external force existing along the center line of the shaft.

[0023] In the process of processing the conveying shaft of the utility model, if two or more shafts apply the tension of the conveying belt, the modeling can be selected on one or more shafts. If the modeling is selected on one shaft, the driving shaft should be selected preferentially. If the modeling is selected on two or more shafts, the modeling of each section should be correspondingly arranged along the center line of the shaft. When the surface of the conveying shaft 2 is modeled, the cutting position of the cutting tool and the cutting depth of the corresponding cutting position are adjusted. For example, when the cutting tool is located at the protruding position of the conveying shaft 2, the cutting depth of the cutting tool is shallower. After the protrusion is cut and polished, the cutting tool is moved aside, the cutting depth of the cutting tool is deeper, and then the recess position is processed. After the recess is recessed, the protrusion on the surface of the conveying shaft 2 is more obvious. The curved surface of the conveying shaft 2 is processed into a specific position, a specific width, an uneven, symmetrical and regular shape relative to the center line of the width of the conveying belt, and the corresponding slopes, recesses and protrusions, such as the first slope 4, the second recess 5, the third slope 6 and the second protrusion 7, are symmetrically arranged on both sides of the center line of the width of the conveying belt.

[0024] In actual application, two or more groups of slopes, recesses and protrusions can be arranged according to the length of the conveying shaft as needed. In principle, each two groups need to be symmetrically arranged about the center line of the first protrusion.

[0025] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
