Description

Technical Field

[0001] This utility model relates to the field of conveying production technology, specifically to a roller with size adjustment function. Background Technology

[0002] Idler rollers are components used in belt conveyors, typically consisting of rollers, bearings, and shafts. They are widely used in mining, coal, ports, power, chemical, and many other fields. The main function of idler rollers is to support the conveyor belt and the material on it, ensuring stable belt operation, reducing belt sagging and friction during operation, lowering running resistance, and thus guaranteeing efficient and reliable material transport by the belt conveyor. They also help extend the service life of the conveyor belt.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Traditional idlers have many limitations in practical use. Regarding length adjustment, most existing idlers are of fixed size, lacking flexibility to meet different conveying needs. If the specifications of the conveying equipment change or the material distribution range changes, idlers that cannot be easily adjusted in length become unsuitable, often requiring complete replacement, which is time-consuming, labor-intensive, and costly. Furthermore, due to the inability to flexibly adjust length, in some special working conditions, such as fluctuations in the width of the conveyed material, the idlers cannot accurately match, easily causing material spillage, accelerated wear on the conveyor belt, and other problems, affecting conveying efficiency and equipment stability. Utility Model Content

[0005] The purpose of this invention is to provide a roller with size adjustment function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roller with size adjustment function, comprising a central housing, side end housings slidably mounted on both sides of the central housing, and the same drive motor rotatably mounted on the lower ends of the two central housings; two first overlapping components are fixedly mounted on both sides of the central housing, and two second overlapping components are fixedly mounted on one side of each of the two side end housings, wherein the second overlapping components and the first overlapping components are interlocked.

[0007] More preferably, an internal circular tube is fixedly installed inside the middle shell, and several positioning holes are opened on both sides of the internal circular tube.

[0008] More preferably, a first bearing is rotatably mounted inside each of the side end housings, and sealing rings are fixedly mounted on both sides of the first bearing.

[0009] More preferably, an inner baffle is fixedly installed inside the side end housing, and an outer baffle is fixedly installed inside the side end housing.

[0010] More preferably, a second bearing is fixedly installed on one side of each of the side end housings, and a connecting plate is fixedly installed on one side of each of the second bearings.

[0011] More preferably, each of the second overlapping components has a positioning tab slidably mounted on its inner wall, the positioning tab engaging with the positioning hole.

[0012] More preferably, threaded rotating rods are rotatably mounted on both sides of the drive motor, and one side of each threaded rotating rod is slidably mounted inside the connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This idler roller breaks through the limitations of fixed dimensions of traditional idlers, and can flexibly adjust its length according to the specifications of the conveying equipment, material distribution and working conditions. This greatly improves the adaptability to different conveying needs, reduces equipment replacement costs and downtime caused by incompatible specifications, and accurately matches the material width under special working conditions, effectively avoiding material spillage and conveyor belt wear, ensuring conveying efficiency and equipment stability, and improving the practicality of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a roller with size adjustment function, including a middle shell 1, side shells 2 slidably installed on both sides of the middle shell 1, and the same drive motor 3 rotatably installed at the lower ends of the two middle shells 1; two first overlapping components 11 are fixedly installed on both sides of the middle shell 1, and two second overlapping components 26 are fixedly installed on one side of each of the two side shells 2, and the second overlapping components 26 are interlocked with the first overlapping components 11.

[0022] In this embodiment, as Figure 1 As shown in the figure, an internal circular tube 12 is fixedly installed inside the middle shell 1, and several positioning holes 13 are opened on both sides of the internal circular tube 12.

[0023] In this embodiment, as Figure 1 As shown in the figure, a first bearing 21 is rotatably installed inside each side end housing 2, and a sealing ring 22 is fixedly installed on both sides of the first bearing 21.

[0024] In this embodiment, as Figure 1 As shown in the figure, an inner baffle 23 is fixedly installed inside the side end housing 2, and an outer baffle 24 is fixedly installed inside the side end housing 2.

[0025] In this embodiment, as Figure 1 As shown in the figure, a second bearing 25 is fixedly installed on one side of each side end housing 2, and a connecting plate 32 is fixedly installed on one side of each second bearing 25.

[0026] In this embodiment, as Figure 1 As shown in the figure, each second overlapping component 26 has a positioning tab 27 slidably installed on its inner wall, and the positioning tab 27 is engaged with the positioning hole 13.

[0027] In this embodiment, as Figure 1 As shown in the figure, threaded rods 31 are rotatably mounted on both sides of the drive motor 3, and one side of each threaded rod 31 is slidably mounted inside the connecting plate 32.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the idler roller with size adjustment function operates as follows during use:

[0029] Firstly, when using the device, the user places it at the designated position on the conveyor belt. When conveying parts or products of different specifications, the size of the device needs to be changed synchronously. By starting the drive motor 3, the threaded rotating rods 31 on both sides are rotated, which in turn moves the connecting plates 32 on both sides. Since the connecting plates 32 are fixedly installed on the sealing rings 22, the side end housings 2 on both sides are moved outward. The inner baffle 23 and the outer baffle 24 are fixedly installed inside the side end housings 2, so the positions of the first bearing 21 and the sealing rings 22 will move together with the side end housings 2. At this time, the second overlapping assembly 26 on one side of the two side end housings 2 and the first bearing 21 on both sides of the middle housing 1 are connected. When the overlapping component 11 detaches, care should be taken not to allow the movement distance to exceed the length of the first overlapping component 11, which would cause the second overlapping component 26 to completely separate from the first overlapping component 11. An internal circular tube 12 is installed inside to prevent waste material from entering the side end housing 2 and the middle housing 1 during transportation, thus affecting the accuracy of the first bearing 21 inside. Several positioning holes 13 of commonly used size distances are opened on the outer surface of the internal circular tube 12. The positioning paddle 27 can be moved to the corresponding positioning hole 13, or it can be moved to any position of the required length. When it is moved to the appropriate position, the drive motor 3 is turned off, and the required conveyor belt is replaced to complete the new transportation work.
