Description

Technical Field

[0001] This utility model belongs to the technical field of rollers for telescopic roller conveyors, specifically a robust telescopic roller conveyor roller. Background Technology

[0002] A roller is a cylindrical, rotatable object in machinery. Rollers are often driven by a power source (such as an electric motor) to move other materials forward or to process materials by generating pressure. They are common components of assembly lines.

[0003] Telescopic roller conveyors are conveyors that use extendable components as their frame. As a high-efficiency, high-reliability, easy-to-assemble, and simple-structure conveying equipment, roller conveyor lines are widely used in various industries for finished product and material conveying, sorting, and online operations.

[0004] In the existing technology, when the rollers of the telescopic roller conveyor are used, the adjusted rollers are often not on the same plane, which makes it impossible for the material to make complete contact with the roller. Uneven force can easily cause scratches and wear on the material surface. In addition, the adjusted roller has poor support strength and is prone to deformation and damage. Summary of the Invention

[0005] The purpose of this invention is to provide a robust telescopic roller conveyor roller that can improve the support strength of the first and second rollers; in addition, it can protect the conveyed material and prevent uneven compression or friction caused by the bottom surface of the material not being in contact with the roller on the same plane.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a robust telescopic roller conveyor roller, comprising a first roller and two second rollers slidably connected to the left and right sides inside the first roller. A rotating shaft is installed at the opposite ends of each of the two second rollers. A support structure is provided inside the first roller. The support structure includes a fixed rod disposed inside the first roller and extending to the interiors of the two second rollers at both ends. A first support plate, fixedly connected to the inner wall of the first roller, is fixedly connected to the middle of the outer wall of the fixed rod. Two second support plates are fixedly connected to the left and right ends of the outer wall of the fixed rod, and all four second support plates are slidably connected to the second rollers.

[0007] The outer wall of the second roller is threaded with multiple sleeves that are flush with the first roller.

[0008] To improve the support strength of the second roller, as a preferred type of robust telescopic roller conveyor of this utility model, multiple stabilizing plates arranged in a ring are fixedly connected between two second support plates located at the same end.

[0009] In order to fix the first roller and the second roller, preferably, the outer wall of the first roller and the two second rollers are connected by countersunk bolts, which is a type of robust telescopic roller conveyor according to this utility model.

[0010] In order to reduce the impact force on the first roller, the first roller, which is a preferred type of telescopic roller conveyor with a robust structure according to this utility model, is preferably equipped with a rubber pad on its outer wall.

[0011] In order to connect the sleeve to the outer wall of the second roller via external thread, preferably, the outer walls of both second rollers are provided with external threads, which is a robust telescopic roller conveyor according to this utility model.

[0012] To make the overall structure more aesthetically pleasing, the rollers used in the telescopic roller conveyor, which are a type of robust structure according to this utility model, are preferably of equal width.

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

[0014] This invention improves the support strength of the first and second rollers by providing a support structure inside the first and second rollers.

[0015] In addition, based on the length of the second roller that has been removed, multiple sleeves are selected and threaded onto the outer wall of the removed part of the second roller. This ensures that the second roller after the sleeves are installed is on the same plane as the first roller, which can protect the conveyed material and prevent the material from being subjected to uneven compression or friction due to the bottom surface of the material not being in contact with the roller on the same plane.

[0020] Please see Figures 1 to 3A robust telescopic roller conveyor roller includes a first roller 1 and two second rollers 2 slidably connected to the left and right sides inside the first roller 1. A rotating shaft 201 is installed at the opposite ends of the two second rollers 2. A support structure is provided inside the first roller 1. The support structure includes a fixed rod 4 disposed inside the first roller 1 and extending to the inside of the two second rollers 2 at both ends. A first support plate 401 fixedly connected to the inner wall of the first roller 1 is fixedly connected to the middle of the outer wall of the fixed rod 4. Two second support plates 402 are fixedly connected to the left and right ends of the outer wall of the fixed rod 4. All four second support plates 402 are slidably connected to the second rollers 2.

[0021] The outer wall of the second roller 2 is threaded with multiple sleeves 3 that are flush with the first roller 1.

[0022] In this embodiment: by setting the first roller 1 and the two second rollers 2 as a telescopic structure, the length of this utility model can be adjusted according to the actual use; and a support structure is provided inside the first roller 1 and the second roller 2, which can improve the support strength of the first roller 1 and the second roller 2. Specifically, the first support plate 401 can support the first roller 1 from the middle, and the second support plates 402 are respectively provided at both ends of the fixed rod 4 to support the second roller 2, thereby improving the bearing capacity of the first roller 1 and the second roller 2, and thus improving the support strength of the first roller 1 and the second roller 2.

[0023] After the first roller 1 and the second roller 2 are adjusted and extended, a height difference will appear between the first roller 1 and the second roller 2. Multiple sleeves 3 can be selected according to the length of the second roller 2 that is moved out and threadedly connected to the outer wall of the moved-out part of the second roller 2, so that the second roller 2 after the sleeves 3 are installed is located on the same plane as the first roller 1.
