Description

Technical Field

[0001] This utility model belongs to the field of idler roller technology, and in particular relates to a detachable idler roller. Background Technology

[0002] Idler rollers are one of the most common items in material transportation. On the one hand, they can carry materials, and on the other hand, they can push and transport the materials placed on them. Idler rollers are mainly composed of three parts: the roller body, the roller shaft, and the linkage. The linkage is mainly a combination of gears or pulleys and belts.

[0003] A Chinese patent application (or patent) with publication number CN221821067U discloses a combined idler roller, comprising: a connecting seat, a roller assembly on top of the connecting seat, the roller assembly including a rotating roller movably mounted on top of the connecting seat, compression holes on the surface of the rotating roller, a support assembly disposed inside the rotating roller, a connecting assembly disposed inside the rotating roller, heat dissipation assemblies disposed at both ends of the support assembly, a rotating shaft movably mounted inside the rotating roller, a support rod fixedly connected to the outer surface of the rotating shaft, and heat dissipation holes inside the support rod. This combined idler roller, by creating compression holes on the outer surface of the rotating roller, facilitates heat dissipation from the inside of the rotating roller. Furthermore, the connecting assembly movably connects the rotating roller to the support assembly, reducing the contact area between the rotating roller and the support assembly, thereby reducing heat generated by friction. The heat dissipation assembly further enhances the heat dissipation effect of the roller assembly by dissipating heat from the surface of the support assembly to the outside of the rotating roller through the compression holes.

[0004] The aforementioned combined idler roller includes an idler roller assembly consisting of a rotating roller and compression holes on its surface. The rotating roller itself is not modular, and its significant weight hinders assembly and disassembly. Furthermore, the rotating roller contains an internal support assembly composed of a rotating rod, a support rod, and ventilation holes. The rotating rod connects to the inner wall of the rotating roller via the support rod, with the end of the support rod inserted into the inner wall. The support rod has a cross-shaped structure and its length is the same as the rotating roller. Disassembly and assembly require lifting and leveling the support rod, and installation also necessitates maintaining its horizontal alignment with the rotating roller. However, the support rod's significant weight makes it difficult to sustainably lift and support its end during assembly. Therefore, we provide a detachable idler roller to address these problems.

Detailed Implementation

[0027] 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.

[0028] Example 1

[0029] Please see Figure 1-3 This utility model is a detachable idler roller, including an idler roller body 1 and a counterweight assembly 2. The weight of the idler roller body 1 can be increased or decreased by using the counterweight assembly 2, thereby realizing the disassembly and assembly of the idler roller body 1.

[0030] Specifically, a counterweight groove 101 is provided on the outer wall of the idler body 1, and the idler body 1 is connected to the counterweight assembly 2 through the counterweight groove 101. The counterweight assembly 2 includes a sealing plate 201 rotatably connected to the outside of the counterweight groove 101, and a counterweight block 202 disposed in the counterweight groove 101.

[0031] Furthermore, a limiting groove 101a is provided on the inner wall of one end of the counterweight groove 101, and a storage groove 202a is provided on the side wall of the counterweight block 202 corresponding to the limiting groove 101a. The inner wall of the storage groove 202a is connected to the positioning block 202b through a spring 202c. The positioning block 202b is located between the limiting groove 101a and the storage groove 202a. A rotating shaft 201a is inserted through one end of the sealing plate 201, and the sealing plate 201 is rotatably connected to the counterweight groove 101 through the rotating shaft 201a. A fixing pin 201b is inserted through the sealing plate 201 at the other end of the rotating shaft 201a.

[0032] The operation process of this embodiment is as follows: When in use, flipping the sealing plate 201 exposes the counterweight groove 101 on the idler body 1. Then, press the positioning block 202b. At this time, the spring 202c is compressed, and the positioning block 202b is also compressed into the storage groove 202a of the counterweight block 202. The counterweight block 202 can then be placed into the counterweight groove 101. When the counterweight block 202 enters the counterweight groove 101, the spring 202c loses its squeezing force and pushes the positioning block 202b into the limiting groove 101a on the side of the counterweight groove 101. That is, the counterweight block 202 is stably fixed in the counterweight groove 101. Finally, insert the fixing pin 201b from the side of the idler body 1 into the sealing block 201b. Repeat this process to install the other three counterweight components 2, thus completing the assembly of the idler body 1. Conversely, disassembling the idler body 1 is achieved by reversing the steps.

[0034] Please see Figure 4-5 Based on embodiment 1, a shaft assembly 3 is also provided. The connection between the round shaft 301 and the roller body 1 can be realized by using the support plate 303. Both the round shaft 301 and the support plate 303 are multi-segment splicing assembly structures, thereby realizing the assembly and disassembly of the shaft assembly 3.

[0035] Specifically, the roller body 1 has side grooves 102 at both ends and an inner sliding groove 103 on its inner wall. The roller body 1 is threadedly connected to the fixing ring 104 through the side grooves 102. The roller body 1 also has a shaft assembly 3 inside. The shaft assembly 3 includes a round shaft 301 that is threadedly connected to each other and a support block 303 that is slidably inserted into the outer wall of the round shaft 301. The other end of the support block 303 is slidably inserted into the roller body 1. Both ends of the round shaft 301 are fixedly connected to a linkage wheel 302.

[0036] Furthermore, one end of the round shaft 301 is provided with a shaft hole 301b, and the other end of the round shaft 301 is welded with a connecting post 301c. One round shaft 301 is threadedly connected to the connecting post 301c of another round shaft 301 through the shaft hole 301b. The outer wall of the round shaft 301 is provided with a insertion groove 301a, and the round shaft 301a is slidably connected to the insertion plate 303a through the insertion groove 301a. The insertion plate 303a is welded to both ends of the support plate 303. The other end of the support plate 303 is provided with a rod hole 303c, and the other end of the support plate 303 is welded with an abutment rod 303b. One support plate 303 is connected to the rod hole 303c on the other support plate 303 through the abutment rod 303b. The center of the linkage wheel 302 is provided with a wheel axle 302a, and the end of the wheel axle 302a is inserted into the end of the outermost round shaft 301 through a fixing block 302b.

[0037] The operation process of this embodiment is as follows: When in use, align the plug plate 303a on the support plate 303 with the inner groove 103 on the inner wall of the roller body 1, and push the support plate 303 into the inner groove 103. Then take out another support plate 303 and operate as above. At this time, the abutment rod 303b on the support plate 303 is inserted into the rod hole 303c of the previous support plate 303. Align the connecting post 301c on one round shaft 301 with the shaft hole 301b on another round shaft 301 and rotate the round shaft 301 to assemble multiple round shafts 301 together. After the assembly is completed, align the plug groove 301a on the round shaft 301 with the plug plate 303a on the other end of the support plate 303 and push it into it to complete the assembly between the roller body 1 and the peripheral assembly 3. Conversely, disassembly is achieved.
