Abstract

The utility model discloses an assembled roller mechanism capable of correcting a deviation, which comprises a central shaft, wherein at least two roller assemblies capable of rolling are arranged on the central shaft, and a spacing ring is arranged between the roller assemblies, so that grooves are formed between the roller assemblies. Compared with the prior art, the utility model has the advantages that: the roller is superior to the roller with the groove manufactured by the traditional machining after the thick-wall pipe is welded, and the bearing is arranged in the roller, so that the installation space of the bearing is saved, the structure is simple, and the maintenance is convenient; because the thin-wall pipe is welded, the weight is lighter, and the material cost is saved. The rollers having the corresponding number of grooves may be assembled according to the number of the deviation preventing guide bars of the conveyor belt.

Description

Assembled roller mechanism capable of correcting belt

Technical Field

The utility model relates to a conveyor roller, in particular to an assembled roller mechanism capable of correcting a belt.

Background

At present, most of traditional conveyor rollers in the market are integrally formed by welding, so that the manufacturing cost is high, and the bearings of the rollers occupy the extra length of the rollers, so that the roller equipment is longer. The roller with the grooves for limiting the belt deflection has thicker outer wall, larger overall weight and correspondingly increased material cost, and has higher requirements on equipment bearing weight. Meanwhile, the existing integrated grooved roller cannot be replaced after the bearing in the roller is damaged, so that the later maintenance is not facilitated. Therefore, developing an assembled roller mechanism with a belt capable of correcting deviation is a problem to be solved by those skilled in the art.

Disclosure of Invention

The utility model aims to solve the defects and provides an assembled roller mechanism capable of correcting a belt.

The above object of the present utility model is achieved by the following technical solutions: the utility model provides an assembled roller mechanism of belt can rectify, includes the center pin, install two at least rollable roller assembly on the center pin, be equipped with the spacer ring between the roller assembly, make the slot formed between the roller assembly.

Further, the roller assembly comprises a cylinder body and bearings, wherein the bearings are arranged at two ports of the cylinder body, and the bearings and the cylinder body are sleeved on the central shaft together.

Further, the bearings are fixed at two ends of the cylinder body through bearing support rings, the bearing support rings are welded at two ports of the cylinder body, and the bearing outer ring is welded at a central hole of the bearing support rings.

Further, positioning rings are arranged at two ends of the central shaft, and compress the bearing inner ring to limit the axial movement of the roller assembly.

Further, the cylinder is made of a thin-walled tube.

Compared with the prior art, the utility model has the advantages that:

1. the roller is superior to the roller with the groove manufactured by the traditional machining after the thick-wall pipe is welded, and the bearing is arranged in the roller, so that the installation space of the bearing is saved, the structure is simple, and the maintenance is convenient;

2. because the thin-wall pipe is welded, the weight is lighter, and the material cost is saved.

3. The rollers having the corresponding number of grooves may be assembled according to the number of the deviation preventing guide bars of the conveyor belt.

Detailed Description

The utility model is further described in detail below with reference to the accompanying drawings.

Example 1: as shown in fig. 1 to 3, an assembled roller mechanism of a belt capable of correcting deviation comprises a central shaft 1, wherein two roller assemblies 2 capable of rolling are arranged on the central shaft 1, each roller assembly 2 comprises a cylinder 201 and a bearing 202, each cylinder 201 is made of a thin-wall pipe, each bearing 202 is arranged at two ports of each cylinder 201, and each bearing 202 and each cylinder 201 are sleeved on the central shaft 1 together; the bearings 202 are fixed at two ends of the cylinder 201 through bearing support rings 203, the bearing support rings 203 are welded at two ports of the cylinder 201, and the outer ring of the bearings 202 is welded at the central hole of the bearing support rings 203; positioning rings 3 are arranged at two ends of the central shaft 1, and the positioning rings 3 press against the inner ring of the bearing 202 to limit the axial movement of the roller assembly 2. A spacer ring 4 is provided between the roller assemblies 2 to form a groove 5 between the roller assemblies 2.

Example 2: as shown in fig. 4, three rolling roller assemblies 2 are mounted on the central shaft 1, and the rest of the structure is the same as that of the embodiment 1.

The assembled roller of the utility model rotates by utilizing the outer ring of the roller to drive the outer ring of the bearing 202 to rotate, and the outer ring roller is assembled into a roller mechanism with the groove 5 through assembling, and can limit the belt from deviating when being used by matching with a conveying belt with an anti-deviation guide bar which can be embedded into the groove 5. Meanwhile, the utility model can assemble the rollers with corresponding grooves according to the number of the anti-deviation guide bars of the conveying belt.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
