Background

The conveyor belt is a belt-shaped conveying mechanism which is assembled on a conveyor and used for conveying objects, and the conveyor belt conveyor is continuously perfected under the influence of technical progress of mechanical manufacturing, motors, chemical industry and metallurgical industry, gradually develops from completion of conveying inside a workshop to completion of material conveying inside an enterprise, between enterprises and even between cities, and becomes an indispensable component part of mechanization and automation of a material conveying system.

Current conveyer usually need be with its tensioning to make its outer wall with the running roller have sufficient frictional force and carry out material transmission, avoid skidding, its structure sets up the conveyer roller wheel into adjustable mode more, or independently sets up the tensioning running roller, and no matter which kind of mode carries out the belt tensioning, and the belt still can take place to loosen and take off because self deformation after using the certain time, influences the transmission of belt, needs to carry out the tensioning many times to the belt and adjusts.

SUMMERY OF THE UTILITY MODEL

To the technical problem that above-mentioned exists, the utility model provides a belt straining device to solve current transmission belt and take place to take off because of deformation easily, need carry out the problem of tensioning when indefinite, this belt straining device can effectively adjust the tensile force to the belt, keeps the tensioning state of belt simultaneously for a long time.

The utility model discloses a belt tensioning mechanism, which comprises a belt, a driving motor, a supporting seat, a driving roller, a driven roller, a tensioning roller, an adjusting shaft, a base and a lifting device, wherein the driving roller and the driven roller are both rotationally arranged on the supporting seat, the driving motor is fixed on the supporting seat, an output shaft of the driving motor is connected with the driving roller, the belt surrounds the peripheries of the driving roller, the driven roller and the tensioning roller, the base is positioned below the supporting seat, the lifting device is connected with the bottom of the base, the lifting device is used for driving the up-and-down displacement of the base, the number of the adjusting shaft is two, two ends of the tensioning roller are respectively rotationally connected with one end of two adjusting shafts, and the other ends of the two adjusting shafts are rotationally connected with the base, the base is provided with a stress detection device, the stress detection device is provided with a spring, and the spring is connected to the middle of the adjusting shaft.

Furthermore, the driving roller and the driven roller are located on the same horizontal plane, and the tensioning roller is located at the bottom of the middle of the driving roller and the driven roller.

Furthermore, elevating gear includes bottom plate and screw rod, the screw rod rotate set up in on the bottom plate, the screw rod insert the base and with base threaded connection.

This belt straining device is when carrying out the tensioning operation of belt, accessible tensioning roller is to the belt stretching to exert the tensile force to the belt, make the belt with initiative running roller and passive running roller all have better attached effect, when carrying out the tensioning, the accessible elevating gear adjusts the height of base, thereby adjust tensioning roller is to the application of force of belt, through atress detection device can indirectly detect right the application of force of belt to can carry out the atress regulation in the certain limit, the regulating spindle with the lever structure that the spring formed can guarantee the tensile force that the belt received in the certain time is unchangeable, even the belt is because long-term the use takes place deformation, and it receives the tensile force also change not very much.
