Description
Technical field
It the utility model is related to Belt Conveying technical field, more particularly to a kind of belt stretcher.
Background technology
Tensioning wheel is the tensioning apparatus of V belt translation, when the centre-to-centre spacing of band can not be adjusted, can use tensioning wheel will with
Tightly.Tensioning wheel is typically located at the inner side of slack list, so that band is only by bend in one direction；Meanwhile to ensure that small pulley cornerite will not
Reduce excessively, tensioning wheel should be installed close proximity to big belt wheel.Existing tensioning wheel cannot adjust the position of disk roller after mounting
Put, therefore, installation is not in place, and tension is smaller, it has not been convenient to adjusts.
China Patent No.：201020231557.3 disclosing a kind of belt stretcher, including adjusting screw and it is erected at
Support body on adjusting screw, adjusting screw are two and consolidated with tensioning wheel that tensioning wheel is described to be rotatably connected on mandrel
Support body can drive tensioning wheel to move.The device is arranged on the both ends of support body by clamping bolt and regulating bolt, on adjusting screw
Screwed hole is provided with, regulating bolt passes through the screwed hole, the length for adjusting regulating bolt by rotating regulating bolt and passing through screwed hole,
So as to drive tensioning wheel to move, move direction of the tensioning wheel away from or close to tail wheel, so as to adjust the tensioning degree of belt；
But need shutdown to be adjusted during regulation, while two regulation screw mandrels of adjustment cause tensioning wheel to tend to balance, adjust
Whole difficulty is high, regulation trouble.
China Patent No.：201420416246.2 disclose a kind of tensioning apparatus of belt, including belt, belt pulley,
Wheel shaft, roller bearing, holder and fixed support, belt bypass belt pulley and power connector, and belt pulley is pacified by roller bearing
On wheel shaft, belt pulley both sides step up to fix by holder limits its axial slip on wheel shaft, on the both ends of wheel shaft
L-type connecting plate is mounted on, the long portion of L-type connecting plate is fixed on wheel shaft, and the short portion of L-type connecting plate is fixed on horizontal stroke by adjustment bolt
Liang Shang, and adjustment bolt passes through the rebound for being welded on crossbeam bottom, crossbeam is arranged on fixed support, by turning adjustment spiral shell

Direct adjustment bolt can quickly adjust the elastic situation of belt, easy to adjust quick, while be welded with transition in crossbeam bottom
Plate, the adjusting range of adjustment bolt can be increased, so as to increase the scope of belt tension degree, while be provided with scale band and
Dial plate can accurately control the distance that the bolt at both ends is screwed into, and ensure that left and right synchronously avoids the inclination of belt pulley, ensure that
The stability of belt transmission；But belt pulley is frequently necessary to the situation by manually observing belt pulley in the course of the work, and
The employee's progress for needing working experience abundant manually turns adjustment bolt and is adjusted.
China Patent No.：201620598669.X disclose a kind of automatic belt tensioning device, including two backstands with
And the roller between the backstand, the roller axial direction are mutually perpendicular to belt movement direction, the backstand
On be provided with screw rod, the roller is enclosed on the screw rod and can moved up and down along the screw rod, and the screw rod passes through both ends
The screw rod is fixed on the backstand by nut, and the screw rod epimere is arranged with spring, the spring one end and the roller
Cylinder connection, the other end are connected with the backstand.The device relies on gravity, the elastic force of spring and the tension force of belt of roller itself
Between be in dynamic balance state, so as to prevent in course of conveying belt pine excessively to skid or tension and pull belt, so as to
Improve the service life of belt.And the automatic belt tensioning device cost, than relatively low, tensile force is constantly in steady state；But
It is that can only be finely adjusted by being in dynamic balance state between the tension force of the gravity of roller itself, the elastic force of spring and belt
It is whole, it can not play large range of adjustment for the more serious belt of aging.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model provides a kind of belt stretcher, and it mainly solves existing skill
It can only be finely adjusted in art by being in dynamic balance state between the tension force of the gravity of roller itself, the elastic force of spring and belt
It is whole, the problem of can not playing large range of adjustment for the more serious belt of aging.
To achieve the above object, the utility model employs following technical scheme：A kind of belt stretcher, including machine
