Description
Technical field
The utility model is related to ribbon conveyer building block technical field, more particularly, to a kind of self-centering idler
Group.
Background technology
Belt conveyor is a kind of important conveying equipment.In actual production running, belt is often because of stress
It is uneven and cause material to trickle down, great potential safety hazard is caused to production, so, people can use tune in course of conveying
Insensitive problem is acted and mostly there is tuningout in heart idler machining, existing idler machining.Therefore, it is possible to design a kind of tuningout action
Sensitive self-centering idler group is very necessary.
Utility model content
In order to make up the deficiencies in the prior art, the utility model provides a kind of self-centering idler group.
The technical solution adopted in the utility model is：
A kind of self-centering idler group, including frame, the frame are respectively fixedly connected with by left gyroaxis, right-hand rotation axle
It is fixed with left roller rack and right roller rack, the left roller rack on left carrying roller, left block roller, the right roller rack
It is fixed with right carrying roller, right block roller；The ring-type being gradually reduced from left to right provided with some diameters on the left end of the left block roller is convex
Play I；The annular projection II being gradually reduced from right to left provided with diameter on the right-hand member of the right block roller；The left roller rack lower end
It is fixed with left lug；The right roller rack lower end is fixed with right lug, is fixed between the left lug, right lug
Extension spring；The frame is additionally provided with cylindrical left limit part, right limit part for limiting extension spring activity, the left limit part,
Right limit part is located at left roller rack, the lower section of right roller rack respectively；The left roller rack, the lower end of right roller rack with
Extension spring is also fixed between frame respectively.
Compared with prior art, its advantage is the utility model：The ring that left block roller left end is provided with the utility model
The annular projection II that shape projection I and right block roller right-hand member are provided with, effectively can rectify a deviation in time to the belt of sideslip, tuningout action
It is sensitive；Moreover, when a side blocking roller, roller rack sideslip under the drive of belt, correction is also participated in the extension spring that offside is provided with；Together
When, the extension spring that left roller rack, right roller rack are respectively fixedly connected with can strengthen aligning effect again.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model self-centering idler group.
Embodiment
As shown in figure 1, a kind of self-centering idler group, including frame 1, frame 1 passes through 3 points of left gyroaxis 2, right-hand rotation axle
It is not fixedly connected on left roller rack 4 and right roller rack 5, left roller rack 4 and is fixed with left carrying roller 6, left block roller 7, right support
Right carrying roller 8, right block roller 9 are fixed with roller support 5；It is gradually reduced from left to right provided with some diameters on the left end of left block roller 7
Annular projection I 10；The annular projection II 11 being gradually reduced from right to left provided with diameter on the right-hand member of right block roller 9；Left carrying roller branch
The lower end of frame 4 is fixed with left lug 12；The right lower end of roller rack 5 is fixed with right lug 13, between left lug 12, right lug 13
It is fixed with extension spring 14；Frame 1 is additionally provided with cylindrical left limit part 15, right limit part 16 for limiting the activity of extension spring 14,
Left limit part 15, right limit part 16 are located at left roller rack 4, the lower section of right roller rack 5 respectively；Left roller rack 4, right carrying roller
Extension spring 14 is also fixed with respectively between the lower end of support 5 and frame 1.
When belt normal operation on carrying roller, belt is not contacted with annular projection I 10, annular projection II 11；Work as belt
On carrying roller slightly to the left sideslip when, annular projection I 10 that left block roller 7 is provided with can apply to belt one it is in opposite direction with sideslip
Active force, the active force in opposite direction with sideslip that belt is applied by the annular projection I 10 being subject to make belt adjust automatically
Partially；Due to the annular projection I 10 being gradually reduced from left to right provided with some diameters on the left end of left block roller 7, therefore, belt is to the left
Sideslip degree is bigger, and belt is bigger in the active force applied by the less annular projection I 10 of diameter being disposed below, simultaneously
The barrier force in opposite direction with belt deviation that the annular projection I 10 being relatively large in diameter positioned at its left side applies is also suffered from, is promoted
Belt automatic deflection adjusting, substantially, after belt is adjusted, the active force of belt and annular projection I 10 reduces tuningout effect again.
When belt, sideslip is to when driving left block roller 7, left roller rack 4 to be deflected along belt direction of travel to the left, in left block roller 7
I 10 pairs of belts of annular projection while rectify a deviation, the extension spring 14 that left roller rack 4 is fixedly connected can give left roller rack
4 applications move active force in opposite direction, and the sideslip of left roller rack 4 is corrected；Meanwhile, right roller rack 5 is consolidated
Surely the extension spring 14 connected can limit right roller rack 5 sideslip to the left, the extension spring being fixed between left lug 12, right lug 13 again
14 can occur elastic deformation because of the sideslip of left roller rack 4, and left limit part 15 can limit extension spring 14 again, extension spring 14 is bypassed left limit
Position part 15, so as to increase the pulling force of the left lug 12 of 14 pairs of extension spring, promotes the belt of sideslip to the left to increase the deformation quantity of extension spring 14
Homing, aligning effect is good.This reality when action principle of the present utility model is with belt sideslip to the left when belt sideslip to the right
It is consistent with new action principle.
