Packaging tape deviation self-checking device suitable for packaging tape conveyor

Abstract

The invention relates to a packaging tape deviation self-checking device suitable for a packaging tape conveyor. Two brackets are symmetrically distributed on the two sides of a packaging tape and arevertically and fixedly installed on a packaging tape conveyor rack, and a transverse beam is horizontally and fixedly connected between the two brackets and is located above the packaging tape; an encoder fixing frame is fixedly mounted at the end of the transverse beam, an encoder is horizontally and fixedly mounted on the encoder fixing frame, an encoder mandrel is fixedly connected to one endof a rotating shaft, and the center line of the encoder mandrel coincides with the axis of the rotating shaft; the rotating shaft is mounted on the transverse beam through a bearing and has the rotation freedom degree; the middle portion of the rotating shaft is provided with a through hole, and the through hole is perpendicular to the central axis of the rotating shaft; a detecting roller shaft is fixedly inserted in the through hole of the rotating shaft, and the center line of the detecting roller shaft is perpendicular to the central axis of the rotating shaft; a detecting roller body is in contact fit with the edge of the packaging tape in an abutting-against manner; a laser sensor is hoisted on the middle portion of the transverse beam, the measuring end of the laser sensor right faces the surface of the packaging tape, and the vibration frequency and the vibration amplitude of the packaging tape are measured through the laser sensor; and a spring and a force sensor are connectedin series between the detecting roller body and the transverse beam.

Description

technical field [0001] The invention belongs to the technical field of detection of belt conveyors, in particular to a belt deviation self-checking device suitable for belt conveyors. Background technique [0002] The belt conveyor plays an important role in coal mine transportation, and the working environment of the belt conveyor is relatively harsh. There is a large amount of coal dust and water vapor in its transportation route, and the long working hours and heavy workload will make the belt conveyor in the working process There are various problems in the process, among which the tape deviation is the most common. [0003] Belt deviation is the phenomenon that the center line of the belt deviates from the center line of the conveyor and deviates to one side during the operation of the belt conveyor. As an important part of the belt conveyor, the belt has the characteristics of large consumption and high price. The cost of the belt can account for 50% of the total cost...

Problems solved by technology

[0004] When the tape deviation is serious, materials are easily spilled on the tape on the return journey, causing waste. At the same time, it will also increase the friction between the roller and the tape, and at the same time cause the edge of the tape and the frame to wear each other, causing the tape to be damaged prematurely. And the service life of the roller is seriously reduced

[0005] There are many reasons for the deviation of the belt, among which the bending vibration of the belt is one of the reasons. The vibration of the belt is the result of the interaction between the idler and the belt, and this vibration will aggravate the wear of the belt and the idler, especially the easy damage to the idler bearing. , leading to the inflexible rotation of the idler roller, which in turn increases the running resistance of the belt conveyor, resulting in the deviation of the belt or even the scraping of the material.

[0006] Once the tape is separated from the idler roller or the tape is scratched, the belt conveyor will not work normally. Due to the continuity of the production process and the series connection between the equipment, if one belt conveyor fails, it will affect the operation of other equipment. Normal operation, resulting in the collapse of the entire production process

[0007] When the deviation of the belt occurs, on the one hand, it needs to be shut down for maintenance, thereby reducing the coal production efficiency; on the other hand, it is easy to cause more serious production accidents such as tearing of the belt and coal pile

[0008] Therefore, in order to avoid various consequences caused by tape deviation, maintenance personnel are required to regularly inspect the running state of the tape, and detect the degree of tape deviation through manual measurement. The traditional manual detection method is not only time-consuming and labor-intensive, but also efficient. It is also very low, and it is increasingly difficult to meet production needs
