Embodiment Construction

[0010] see figure 1 , 2 , The pneumatic roller includes a roller body 1 and support bearings 2 at both ends of the roller body 1 . There is a pneumatic assembly inside the roller body 1; It is a schematic structural diagram of a typical pneumatic assembly, which uses a double-hole eccentric motor and a three-stage planetary gear reducer.

[0011] Roller body 1 right-hand side bearing 2 middle part has air-intake pipeline 7, and air-intake pipeline 7 li ends are connected with air-intake guide piece 8, air-intake reversing piece 9 and air motor 4, and the bearing sleeve 10 has exhaust hole on it. The air intake guide block 8 guides the high-pressure air entering from the air intake line 7 into the air motor 4 air inlet on the edge, and the air intake reversing block 9 reverses the direction of the air inlet when the roller body 1 is operated in reverse. The air motor 4 includes a rotor 12 , a stator 13 , and a rear end cover 14 . The speed reducer 5 includes a speed reducer...

Abstract

The invention relates to a driving roller for a conveying mechanism, namely a pneumatic roller. The pneumatic roller comprises a roller body, support bearings at two ends of the roller body and a pneumatic assembly. The pneumatic assembly is composed of an air inflow pipeline, a pneumatic motor and a decelerator. An output wheel of the decelerator is connected with the inner wall of the roller body. The air inflow pipeline is in the middle of the bearing at one end of the roller body. The inner end of the air inflow pipeline is connected with an air inflow guide block, an air inflow reversing block and the pneumatic motor. An exhaust hole is arranged on a bearing sleeve. The pneumatic roller self finally rotates by taking compressed air as a power source through conversion and transfer of a series of force so that the purpose of transporting objects is achieved. The pneumatic roller can be used in special working environments, such as explosive working environments, corrosive working environments, high-temperature working environments, moisture working environments and the like. The pneumatic roller has the characteristics of long service life, less maintenance, continuous working, frequent starting, simple installation, convenience for disassembly and convenience for realizing stepless speed regulation and using clean energy.

Description

technical field [0001] The invention relates to a driving roller for a conveying mechanism, that is, a pneumatic roller (or a pneumatic roller). Background technique [0002] In the prior art, the driving roller of the conveyor is an electric roller, which has been widely used in mining, metallurgy, chemical industry, coal, building materials, electric power, food and transportation and other departments. Its advantages are simple and compact structure, small footprint, and simple and convenient installation. However, it also has many limitations, such as the use of special structures in explosive, corrosive, high-temperature and humid working environments; it cannot work continuously for a long time; the motor will burn out under overload, etc.; especially when explosion-proof is required Occasions and when continuous work is required, its structure is large in size, heavy in quality and high in cost. Contents of the invention [0003] The object of the present inventio...
