Description

Technical Field

[0001] This utility model relates to the technical field of conveying machinery and equipment, and in particular to a conveyor roller. Background Technology

[0002] Belt conveyors are primarily used for transporting materials. They mainly consist of rollers at both ends, idlers in the middle for support, a frame, and a rotating belt. The idlers are rotatably mounted on the frame, and the belt rotates around them. Traditional idler structures are relatively simple, consisting of just a plain shaft. This type of structure makes the belt prone to misalignment during operation, which can subsequently affect the normal use of the conveyor. Utility Model Content

[0003] The present invention aims to address the shortcomings of the prior art by providing a conveyor idler roller.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A conveyor idler includes an idler body with frustum-shaped expanded diameter ends at both ends. A rotating shaft is installed on the outer end face of the frustum-shaped expanded diameter ends. The idler body has threaded sections in opposite directions from the middle to both ends. An adjusting and pressing roller assembly is provided at the upper end of both ends of the idler body.

[0006] The adjusting pressure roller assembly includes a crossbeam. One end of the crossbeam has a connection hole for fixing to the conveyor frame, and the other end of the crossbeam has an adjusting screw. Adjusting nuts are screwed onto both the upper and lower surfaces of the crossbeam on the adjusting screw. An n-shaped frame is provided at the bottom of the adjusting screw, and a pressure roller is rotatably installed between the two side plates of the n-shaped frame.

[0007] One end of the shaft is provided with a connecting end plate, which is fixed to the outer end face of the frustum-shaped expanded diameter end by bolts.

[0008] The beneficial effects of this utility model are: the truncated cone-shaped expanded diameter ends at both ends of this utility model can form a certain obstruction on both sides of the belt, forming a first-level anti-deviation measure. Furthermore, through the oppositely spiraled threaded sections at both ends, the belt is always centered for conveying, forming a second-level anti-deviation measure. Additionally, the upper surfaces on both sides of the belt can be pressed by the pressure rollers, forming a third-level anti-deviation measure, thus having a very good deviation correction function.

[0012] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0013] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0014] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figure 1 As shown, a conveyor roller includes a roller body 1. The roller body 1 has frustum-shaped expanded diameter ends 2 at both ends. A rotating shaft 3 is installed on the outer end face of the frustum-shaped expanded diameter ends 2. A connecting end plate 6 is provided at one end of the rotating shaft 3. The connecting end plate 6 is fixed to the outer end face of the frustum-shaped expanded diameter ends 2 by bolts 7.

[0018] The roller body 1 and the truncated cone-shaped expanded end 2 have a weight-reducing through hole.

[0019] The roller body 1 has threaded sections 4 in opposite directions from the middle to both ends, and the upper ends of both ends of the roller body 1 are provided with adjusting and pressing roller assemblies 5.

[0020] This utility model can form a certain obstruction on both sides of the belt through the frustum-shaped expanded diameter ends 2 at both ends of the roller body 1, forming a first-level anti-deviation measure. Furthermore, through the threaded sections 4 at both ends with opposite directions of rotation, the belt supported by them is subjected to a guiding force pointing towards the center of the belt, ensuring that the belt does not deviate or slip, and that the belt is always transported in the center, forming a second-level anti-deviation measure.

[0021] The adjusting pressure roller assembly 5 includes a crossbeam 51. One end of the crossbeam 51 is provided with a connection hole 52 for fixing to the conveyor frame, and the other end of the crossbeam 51 is provided with an adjusting screw 53. Adjusting nuts 54 are screwed onto the upper and lower surfaces of the crossbeam 51 on the adjusting screw 53. An n-shaped frame 55 is provided at the bottom of the adjusting screw 53, and a pressure roller 56 is rotatably installed between the two side plates of the n-shaped frame 55.

[0022] The bottom of the crossbeam 51 is provided with an auxiliary connecting plate 57, which is sleeved on the rotating shaft 3.

[0023] The adjusting pressure roller assembly 5 can press the upper surfaces of both sides of the belt with the pressure roller 56, forming a third-level anti-deviation measure. The position of the pressure roller 56 can be adjusted by adjusting the adjusting nut 54.

[0024] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
