Abstract
The utility model relates to a belt-tensioning and deviation-regulating device of a belt conveyer, which is installed below a machine frame and above a belt and is composed of a circular shaft rod, a movable frame, and a deviation-regulating gravity roller which supports on the belt by means of self weight. The utility model can lead a belt machine to keep definite values for belt tension when materials change continuously and runs, and consequently, the precision of an electronic belt scale can be ensured. Both ends of the utility model are provided with deviation-regulating gravities with inverse conical structures. The roller can automatically regulate the deviation of the belt, can ensure the normal running of the belt machine, and can improve the precision of a belt scale. The belt-tensioning and deviation-regulating device of a belt conveyer simple structure, strong practicality, and obvious effects of solving belt tension and regulating deviation.
Description
The utility model belongs to the regulating mechanism of band conveyor, specifically a kind of belt tension of proportioning belt conveyer and deviation correcting device.
Ingredients belt is in operational process, keep the constant tension force of belt very important, because the variation of belt tension directly has influence on the accuracy of the belted electronic balance in the ingredients belt, belt tension adjustment way commonly used at present is to adorn two to regulate bolt at roller two of belt feeder one end, as (6) among Fig. 1, the dependence bolt is in operation, manual operation is adjusted to optimum regime with belt tension, but because the weight of material of being carried on the belt is all changing at any time, cause the tension force of belt also to change at any time, thereby have influence on the accuracy of belted electronic balance.In order to prevent the belt deviation of belt feeder, usually at two edges of belt two edger rolls are installed and are stoped belt deviation, but because the length of ingredients belt is generally 3～5 meters, edger roll is too near apart from stoichiometric point, therefore, the metering influence to belt conveyer scale is bigger partially in upright rod resistance.
The purpose of this utility model is to provide a kind of belt tension and deviation correcting device of later-model ingredients belt, at the accuracy that does not influence belt conveyer scale, do not influence again on the basis of the normal operation of ingredients belt, belt tension and tuningout function are only finished with a device, and realized automatic dynamic adjustments.
Belt tension and deviation correcting device by a kind of ingredients belt that the utility model proposes, be installed on the below of belt feeder fixed mount, it is by round shaft bar, tressel and offset-regulating gravity roller are formed, round shaft bar is installed in the square hole of fixed mount, the outstanding fixed mount below that inserts in, be up and down cooperation, the welding of round shaft bar bottom is tressel fixedly, one axis hole is respectively arranged on the tressel two side wall panels, the main shaft of offset-regulating gravity roller is installed in the axis hole, is cylinder in the middle of the offset-regulating gravity roller, and cylinder length is slightly larger than belt width, two ends are relative inverted cone structure, and offset-regulating gravity roller is held load-bearing according to himself weight by the belt of belt feeder below.
Fig. 1 is for being equipped with ingredients belt structural representation of the present utility model.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model lateral plan.
Below in conjunction with embodiment the utility model is explained in detail.
In ingredients belt fixed mount (2) below, the utility model is housed, be belt tension and deviation correcting device, it is by round shaft bar (1), tressel (4) and offset-regulating gravity roller (3) are formed, round shaft bar (1) is inserted in the square hole of fixed mount (2), the welding of round shaft bar lower end is tressel (4) fixedly, on tressel (4) two side wall panels axis hole is arranged, offset-regulating gravity roller (3) is a metal solid roll, in the middle of it is cylinder, two ends are relative inverted cone structure, and the main shaft of offset-regulating gravity roller inserts in the axis hole of tressel (4) two side wall panels, are close to support by the belt (5) of band conveyor below the offset-regulating gravity roller.
Principle of the present utility model and move as follows: when the proportioning belt conveyer moves, this device since the deadweight of offset-regulating gravity roller the belt below the frame is pressed down, make belt keep a tension force, because contained weight of material changes on the belt of belt feeder top, therefore the automatic play up and down by offset-regulating gravity roller remains on certain numerical value the tension force of belt, thereby guarantees the accuracy of belted electronic balance (7).In addition, because the offset-regulating gravity roller both sides are relative inverted cones, therefore, when belt deviation moves towards the inclined-plane of cone, cause the overbalance of the tension force of belt two edges, can automatically belt be shifted to the tram of central authorities, play the automatic deflection adjusting effect, to guarantee the normal operation of belt feeder.
The utility model is simple in structure, only needs to increase a dingus and just can solve belt tension and sideslip problem on existing band conveyor, and practical, effect is obvious.
Claims (3)
1, a kind of belt tension of proportioning belt conveyer and deviation correcting device, it is characterized in that forming by round shaft bar, tressel and offset-regulating gravity roller, round shaft bar is installed on belt feeder fixed mount below, outstanding inserting in the square hole of fixed mount, the welding of round shaft bar bottom is tressel fixedly, one axis hole is respectively arranged on the tressel two side wall panels, the main shaft of offset-regulating gravity roller is installed in the axis hole, be close to support by the belt of band conveyor below the offset-regulating gravity roller.
2, by the belt tension and the deviation correcting device of the described belt feeder of claim 1, the centre that it is characterized in that offset-regulating gravity roller is a cylinder, and two ends are relative inverted cone structure.
