The utility model discloses a be in the dynamic balance state between the tension of the gravity of automatic belt tensioning device dependence roller self, the elasticity of spring and belt to prevent in transportation process the belt excessively the pine skid or tension and pull the belt, play a fine guard action to the belt, improve the life of belt.
Description
Technical field
This utility model is related to Belt Conveying technical field, particularly to a kind of automatic belt tensioning device.
Background technology
This automatic belt tensioning device is to be used in rubber machinery industry, above rubber production line.In these industries
On some belt transport units, belt can occur the length change of belt with the rotation of pivoted arm, different according to the angle rotating,
The length of production line is different, and the length change amount of belt is also different, when the length change amount of belt is very big, will pull
Belt, shortens the service life of belt, if the margin reserves of belt are excessive, make belt be in relaxed state, will make belt
Directly skid with roller.Above-mentioned two situations all can directly contribute economic loss, brings very big problem to production line.
Utility model content
The technical problems to be solved in the utility model is to provide one kind to prevent belt slippage and belt quilt in Belt Conveying
The automatic belt tensioning device pulled.
In order to solve above-mentioned technical problem, scheme of the present utility model is: a kind of automatic belt tensioning device, including two
Backstand and the roller between described backstand, described roller axial direction and belt movement direction are mutually perpendicular to, institute
State and be provided with screw rod on backstand, described roller is enclosed within described screw rod and can move up and down along described screw rod, described screw rod leads to
Described screw rod is fixed on described backstand the nut crossing two ends, and described screw rod epimere is arranged with spring, described spring one end
It is connected with described roller, the other end is connected with described backstand.
Preferably, described roller and described backstand junction are provided with back-up ring.
Preferably, described spring is all fixedly connected with described roller, backstand.
Preferably, described roller is made up of metal material.
Compared with prior art, the beneficial effects of the utility model are:
Automatic belt tensioning device of the present utility model relies on the tension force of the gravity, the elastic force of spring and belt of roller itself
Between be in dynamic balance state, thus prevent in course of conveying belt pine excessively to skid or tension and pull belt, to skin
Band plays a good protective effect, thus improving the service life of belt.And this automatic belt tensioning device cost compares
Low, tensile force is constantly in steady state, and therefore practicality is stronger.
Brief description
Fig. 1 is the structural representation of the automatic belt tensioning device of this utility model embodiment.
In figure: 81- backstand, 82- roller, 83- screw rod, 84- nut, 85- spring, 86- back-up ring.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.Here it should be noted that
Explanation for these embodiments is used to help understand this utility model, but does not constitute to restriction of the present utility model.This
Outward, as long as involved technical characteristic in each embodiment of this utility model disclosed below does not constitute conflict each other
Just can be mutually combined.
With reference to Fig. 1, automatic belt tensioning device, including two backstands 81 and between described backstand 81 by
The roller 82 that metal material is made, described roller 82 and the frame for carrying belt are vertically arranged, the axis direction of roller 82
It is mutually perpendicular to the direction of motion of belt.Screw rod 83 is provided with described backstand, described roller 82 is enclosed within described screw rod 83,
Described roller 82 can slide up and down along described screw rod 83.Described screw rod 83 is fixed on by described screw rod 82 by the nut 84 at two ends
On described backstand 81, described screw rod 83 epimere is arranged with spring 85, and described spring 85 one end is connected with described roller 82, another
End and described backstand 81 connect.
Described roller 82 is provided with back-up ring 86 with described backstand 81 junction.Described spring 85 all with described roller 82,
Backstand 81 is fixedly connected.
Operation principle of the present utility model is: when belt extends, the tension force of belt can make roller 82 move upwards, works as skin
When the tension force of band reaches a dynamic balance state with the gravity of roller 82 itself and spring 85 elastic force, roller 82 stops rising.
When roller 82 is moved upwards up to certain position, the gravity of roller 82 itself and the elastic force of spring 85 again can be with the tension force of belt 13
Keep a dynamic balance state.In the same manner, when belt tension reduces, the elastic force of the weight of roller 82 and spring 85 can be more than
The tension force of belt, at this moment roller 82 can move down.When roller 82 is moved down into certain position, roller 82 gravity of itself
A dynamic balance state can be kept with the elastic force of spring 85 with the tension force of belt, the process that roller 82 moves down is one again
Absorb the process of unnecessary belt.So go round and begin again, the gravity of the tension force of belt and roller 82 itself, the elastic force of spring 85 are eternal
Being in dynamic balance state, thus reaching protection belt, so that belt service life is not reduced.
Therefore, automatic belt tensioning device of the present utility model rely on the gravity of roller 82 itself, the elastic force of spring 85 with
It is in dynamic balance state, thus preventing the excessively loose skidding of belt in course of conveying or tension and pulling between the tension force of belt
Belt, plays a good protective effect, thus improving the service life of belt to belt.And this belt transportation system cost
Ratio is relatively low, and the tensioning of automatic belt tensioning device is constant, and practicality is stronger.
Above in association with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, in the case of without departing from this utility model principle and spirit, right
These embodiments carry out multiple changes, modification, replacement and modification, still fall within protection domain of the present utility model.
