Regulating mechanism for stably regulating tension of carrier roller belt

Abstract

The invention discloses a regulating mechanism for stably regulating the tension of a carrier roller belt. The regulating mechanism comprises a regulating platform, a drawn wire, a supporting frame and a fence body. An air cylinder and a baffle which are connected with each other are arranged on the regulating platform. A pressure sensor is installed between the tail end of the air cylinder and the baffle. The pressure sensor is connected with a drive device of the air cylinder through a wire. An idler wheel is installed at the telescopic end of the air cylinder and connected with a pulley block through the drawn wire. A roller is rotationally arranged on the fence body. The regulating mechanism further comprises a winding mechanism arranged on the regulating platform. The start end of the drawn wire is fixed to the regulating platform and the tail end of the drawn wire is connected with the winding mechanism. The drawn line, similar to the belt is loosened after working for a long time and the air cylinder needs to move a longer distance to achieve the regulating function at this time. The loosened drawn wire can be tightened again through the winding mechanism arranged on the regulating platform, unnecessary output of the air cylinder is reduced, and meanwhile fine regulating efficiency of the air cylinder to the belt is improved.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to an adjustment mechanism for stably adjusting the tension force of the idler belt. Background technique [0002] Belt conveyors generally include traction parts, load-bearing components, driving devices, tensioning devices, redirection devices and support parts, etc. The traction parts are used to transmit traction, and conveyor belts, traction chains or wire ropes can be used; the load-bearing components are used to hold materials. , There are hoppers, brackets or spreaders, etc.; the driving device provides power to the conveyor, and is generally composed of an electric motor, a reducer and a brake (terminator); the tensioning device generally has two types of screw type and heavy hammer type, which can be used The traction parts maintain a certain tension and sag to ensure the normal operation of the belt conveyor; the support parts are used to support the traction parts or load-bearing compo...

AI Technical Summary

Problems solved by technology

[0003] After the ordinary belt conveyor is used for a long time, the belt will slack to a certain extent, which will cause the center of gravity of the material on the belt to be unstable, or the transmission efficiency will drop sharply. At this time, the usual method is to use a tensioning device to tension the belt. The adjustment of the tension makes the belt return to the normal working level, but in the adjustment process of the tensioning device, the belt is generally pulled to increase the tension of the belt, and when the belt is pulled, the pull If the pulling force is not well grasped, the belt will be too tight, which will increase the working load of the belt conveyor. If the pulling force is too small, the belt will be too loose, and the transmission efficiency of the belt will be low.
