Embodiment
A kind of embodiment of the present utility model shown in attached Fig. 1 and 2, it has base 1, upper bracket 2, medium-height trestle 3, expansion tightening wheel 4, tension shaft 5, tensioner axle bed 6, motor 7, electric control box 8, position limit switch 9, sensor 10, push rod 11, flexible adjustment device 12, slide block 13 and leading screw 14; The front end of upper bracket 2 is fixed with expansion tightening wheel 4, the nearly middle part of upper bracket 2 and the front end of medium-height trestle 3 are hinged, the rear end of the rear end of upper bracket 2 and medium-height trestle 3 is equipped with and makes both flexible adjustment devices 12 of trending towards fitting of upper bracket 2 and medium-height trestle 3, such connecting means also has the effect of damping simultaneously, coming off of each component of avoiding to shake and causing, the rear end of medium-height trestle 3 is hinged on the medium-height trestle support arm 1-1 of base 1, and the induction contact of sensor 10 is relative with sensor block to be separately fixed on medium-height trestle 3 and the upper bracket 2; The output shaft of motor 7 connects leading screw 14, and slide block 13 slides on leading screw 14, and the front end of the front end of push rod 11 and medium-height trestle 3 is hinged, and the rear end of push rod 11 is hinged on the slide block 13.Flexible adjustment device 12 is made up of spring leading screw 12-1, the spring 12-2 and the adjusting nut 12-3 that are enclosed within on the spring leading screw, spring leading screw 12-1 passes the rear end of upper bracket 2 and the rear end of medium-height trestle 3, and the both sides that are positioned at upper bracket 2 and medium-height trestle 3 on the spring leading screw 12-1 are provided with spring 12-2 and adjusting nut 12-3 respectively.Slide block 13 is provided with the limit switch 9 of its sliding stroke of control, and the shifting block of control position limit switch 9 also is installed on the slide block 13, and when motor 7 actions, shifting block can move along with the action of slide block 13.If belt is after continuous tensioner, shifting block pushes the limit switch 9 of a side, and the belt tension automatic controller is just no longer realized the tensioner function, so just is unlikely to make controller for belt tightening to damage; Continue to realize the tensioner function as need, the position that then needs to reinstall controller for belt tightening, thus the limit switch 9 that guarantees opposite side is unlikely to break controller for belt tightening self when spacing, and work is good.Also be provided with two slide bars 15 parallel with leading screw 14 on the belt tension automatic controller, slide block slides along leading screw 14 and slide bar 15, makes that the slip of slide block 13 is more firm.Upper bracket 2 front ends have opening, also are fixed with tensioner axle bed 6 on upper bracket 2, and expansion tightening wheel 4 just can be connected on the tensioner axle bed 6 by tension shaft 5 bearings easily.Motor 7 and electric control box 8 all are fixed on the base 1, and the circuit control system of belt tension automatic controller is flocked together, and make whole structure compact more, and occupation space is also littler.Expansion tightening wheel 4 is to adopt the hard aluminium alloy manufacturing, has light weight, advantages of high strength, considerably beyond common Cast Steel, the anodizing technology is adopted on the surface of expansion tightening wheel 4, makes hardness and degree of finish improve several times, because expansion tightening wheel 4 surface oxide layers are wear-resisting, non-conductive, can not produce static, guaranteed the working life of belt.
Introduce using process of the present utility model according to Figure of description more below:
Initial stage installs the belt tension automatic controller, and when belt was in running order, expansion tightening wheel 4 was in contact condition all the time with belt, and expansion tightening wheel 4 can be decided by regulating adjusting nut 12-3 with the size of belt contact pressure.Have suitable distance between the induction contact of sensor 10 and the sensor block, sensor 10 does not produce signal.After the elongation of belt work a period of time, the pressure of belt and expansion tightening wheel 4 can diminish gradually, when the pressure of belt and expansion tightening wheel 4 elastic pressure less than spring 12-2, flexible adjustment device 12 will the generation effect make the rotation of upper bracket 2 small angles, the induction contact of sensor 10 and the distance between the sensor block diminish, sensor 10 sends signal and transmits signals to electric control box 8,7 work of electric control box 8 commander's motors, under the effect of motor 7 (motor 7 is a reducing motor), slide block 13 slides to left side as shown in Figure 1 along leading screw 14 and slide bar 15, drive push rod 11 actions that are hinged on the slide block 13 thereupon, push rod 11 upwards pushes up upper bracket 2 and medium-height trestle 3, upper bracket 2 and medium-height trestle 3 are upwards also being rotated in the top by push rod 11, the expansion tightening wheel 4 that is installed on the upper bracket 2 is upwards raised, expansion tightening wheel 4 contacts more closely with belt like this, thereby the pressure between expansion tightening wheel 4 and the belt can increase gradually, when the pressure between expansion tightening wheel 4 and the belt during greater than the pressure of spring 12-2, flexible adjustment device 12 acts on upper bracket 2 the small angle rotation takes place, distance between the induction contact of sensor 10 and the sensor block becomes big, motor 7 quits work, thereby finished once tensioner work to belt, when belt extended once more, then the belt tension automatic controller repeated above-mentioned action.Shown in Figure of description 2, to stablize for making to connect between each component of controller for belt tightening, the upper bracket 2 and the medium-height trestle 3 of controller for belt tightening all are designed to frame structure.
This belt tension automatic controller, the induction contact of sensor 10 is relative with sensor block to be separately fixed on medium-height trestle 3 and the upper bracket 2, in the course of the work, because the small angle rotation takes place in upper bracket 2 under the effect of flexible adjustment device 12, the induction contact and the sensor block relative position that cause sensor 10 change, sensor 10 sends signal and gives electric control box 8, thereby control motor 7 startup and stop, so the utility model combines intelligent control system and mechanical structure, make this belt tensioner more reasonable, suitable.
Belt tension automatic controller of the present utility model can use case protected in part except that expansion tightening wheel 4, if when being installed in outside work, the rotary bearing of expansion tightening wheel 4 can also being installed in the wheel hub and with end cap and sealing.
The expanding force of belt tension automatic controller of the present utility model can adapt to various types of other belt transmission equipment in 5～100kg/cm scope, determine required expanding force according to the width of active power, speed and the belt of equipment.If expanding force is too high, can cause power consumption to increase, if expanding force is low excessively, can cause belt slippage inadequately, so very important of the size of adjustment expanding force because of the coefficient of waste.In practical operation,, be exactly constant in case set as long as it is non-slip to be transferred to belt.The utility model has solved the difficult problem in the belt transmission equipment, and the working efficiency of machinery improves, and prolong the working life of belt, and operator's labor intensity reduces, and cost descends, and output increases, because belt operates steadily, energy-saving effect is also comparatively obvious.
