Abstract
The invention relates to a cylinder entrainment detecting unit for belt conveyers. The cylinder entrainment detecting unit comprises a detecting roller; two ends of the detecting roller are rotatably connected to a moving support; the upper end of the moving support is rotatably fixed to a fixed support; being of certain height, the detecting roller can approach a cylinder; when the diameter of a rubber belt wrapping the cylinder increases, the detecting roller can be driven to swing around the fixed support in a direction leaving the cylinder; a position switch used for transmitting electrical signals to a control system if detected skewing of the moving support or the detecting roller reaches a set value is fixed on the fixed support. When material carried by the lower part of the rubber belt enlarges the tail part, at the tail cylinder, of the rubber belt and deviates the detecting roller, the detecting unit sends out electrical signals to allow timely stoppage and cleaning, deviation of the rubber belt is prevented, sharp parts of the material are avoided prickling the rubber belt and the surface of the cylinder, and the service life of the cylinder and that of the rubber belt are prolonged.
Description
Technical field
The present invention relates to a kind of for detecting with or without the detecting device being mingled with material between the stern barrel of belt conveyer and belt, specifically a kind of belt conveyor ' s pulley material folding detecting device.
Background technology
Belt conveyer is in the process of convey materials, adhesive tape material is caused to fall into lower tape surface from tape edge sometimes because a variety of causes is as excessive in mass transport amount, discharging point misaligns etc., and move to conveyer stern barrel place with lower adhesive tape, thus enter between stern barrel and adhesive tape, and the upper surface of lower adhesive tape is fallen again with rotation to the lower surface of adhesive tape of cylinder, enter between cylinder and adhesive tape.So repeatedly, tail wheel and adhesive tape are on the increase with being mingled with material, thus cause rubber belt from deviating, What is more, and the sharp parts in material can puncture adhesive tape and cylinder surface, and cause cylinder to cast glue and damage, adhesive tape is torn, and has a strong impact on enterprise and produces.
The above-mentioned material phenomenon that is mingled with has certain eventuality and hysteresis quality in adhesive tape operational process, controls and does not know, be found, but impact the production of enterprise until Shi Caihui torn by adhesive tape in when often occurring.
Summary of the invention
The object of this invention is to provide a kind of belt conveyor ' s pulley material folding detecting device, whether material folding can be detected between tail wheel and adhesive tape, and sends signal in time middle control according to material folding situation, shut down cleaning foreign matter to allow Central Control Room make arrangements.
