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, Fig. 2, belt transportation system, including the frame 1 for carrying belt 13, described frame 1 is provided with
Leg 2, is provided with crossbeam 3 between described leg 2, described frame 1 one end is provided with swing arm 4, described swing arm 4 is wound with belt 13,
Described swing arm 4 is hinged with described frame 1, and described swing arm 4 is driven by the cylinder 5 being arranged on described crossbeam 3 and waves, described pendulum
The motor 14 of driving belt 13 motion is provided with arm 4.Described frame 1 other end is provided with the first driven roll bypassing for belt
6, described frame 1 is provided with described swing arm 4 junction and coordinates the second driven roll 7, described crossbeam 3 with described first driven roll 6
On be provided with across the automatic belt tensioning device 8 between described crossbeam 3 and described frame 1, belt 13 bypass described belt from
Dynamic tensioner 8.
With reference to Fig. 3, belt auto-tensioning fills 8 and includes two backstands 81 and the roller between described backstand
82, it is mutually perpendicular between described roller 82 and described frame 1, described roller 82 is provided with back-up ring with described backstand 81 junction
86.It is provided with screw rod 83, described screw rod 83 is fixed on institute by nut 84 by the two ends of described screw rod 83 in described backstand 81
State on backstand 81.Described screw rod 83 epimere is arranged with spring 85, and described spring 85 one end is connected with described roller 82, the other end
It is connected with described backstand 81.
In described frame 1, described automatic belt tensioning device 8 both sides are provided with the first carrying roller bypassing for belt 13
9,10, described frame 1 is connected side and is provided with the second carrying roller 11 bypassing for belt 13 with described swing arm 4, and described swing arm 4 sets
It is equipped with the 3rd carrying roller 12 bypassing for belt 13.
Operation principle of the present utility model is: the motor 14 above swing arm 4 drives belt 13 to move and then drive roller 82
Rotate.When cylinder 5 extends, swing arm 4 is in the position parallel with frame 1, as shown in figure 1, when cylinder 5 shrinks, at swing arm
In state orthogonal with frame 1.Swing arm 4 is by the change in location parallel with frame 1 to this mistake of the state vertical with frame 1
Cheng Zhong, the length that belt 13 is actually needed, to supply without unnecessary belt, then belt 13 can be made itself to draw
Long, thus pulling belt 13, reduce the service life of belt.In this utility model, the belt needing supply can be from belt
Obtain inside automatic takeup 8.When belt 13 extends, the tension force of belt 13 can make the roller in automatic belt tensioning device 8
Cylinder 82 moves upwards, when the tension force of belt 13 reaches a dynamic balance state with the gravity of roller 82 itself and spring 85 elastic force
When, roller 82 stops rising.During roller 82 rises, the length of belt 13 can be elongated, thus be supplied to swing arm 4 by with
The belt that the parallel change in location of frame 1 needs during this to the state vertical with frame 1.In the same manner, when swing arm 4 by with machine
To during with frame 1 parastate during this, required belt 13 can shorten the vertical change in location of frame 1, at this moment will be many
Remaining a part of belt is out.The tension force of belt 13 is made to reduce, belt is many, can cause belt slippage.When belt 13 tensile force reduces
When, in automatic belt tensioning device 8, the elastic force of the weight of roller 82 and spring 85 can be more than the tension force of belt 13, at this moment roller 82
Can move down.When roller 82 is moved down into certain position, the gravity of roller 82 itself and the elastic force of spring 85 again can and
The tension force of belt 13 keeps a dynamic balance state, and the process that roller 82 moves down is the mistake of a unnecessary belt of absorption
Journey.So go round and begin again, the gravity of the tension force of belt 13 and roller 82 itself, the elastic force of spring 85 are in dynamic equilibrium shape forever
State, thus reaching protection belt, makes belt service life not reduce.
Therefore, belt transportation system of the present utility model is opened automatically due to the belt being provided between crossbeam and frame
Tight device 8, automatic belt tensioning device 8 relies between the tension force of gravity, the elastic force of spring 85 and belt 13 of roller 82 itself
It is in dynamic balance state, thus preventing the excessively loose skidding of belt 13 in course of conveying or tension and pulling belt 13, to skin
Band 13 plays a good protective effect, thus improving the service life of belt.And this belt transportation system cost ratio is relatively low,
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.
