Abstract
The utility model relates to an aligning device for the deflection of a conveyer belt, comprising a left and a right support arms, a left and a right rollers. The left and the right support arms are welded on the tension wheel carrier of the conveyer belt and are vertical to the axis direction of a tension wheel. The other ends of the left and the right support arms are respectively provided with the left and the right rollers. When the conveyer belt deflects and touches the rollers, the rollers transmit pressure to the tension wheel carrier through the support arms to automatically adjust an included angle between the motion directions of the tension wheel and the conveyer belt into the vertical state, so that the conveyer belt does not deflect.
Description
The utility model relates to the adjusting mechanism of speed governing constant feed weigher belt conveyor, specifically, is a kind of automatic regulating apparatus that prevents that speed governing from quantitatively use for the scale belt deflection.
The belt conveyor of speed governing constant feed weigher usually can form " sideslip " because the running velocity on both sides is different, this be a kind of " common disease ".Light then make the material spilling that is transported, influence measuring accuracy, heavy then belt is rolled, break away from frame, and lead to grave accident.The common method that prevents is to install, when debugging, be strict with, guaranteeing precision.But because belt is to make with elastomeric material, after using after a while, the elasticity of each different sections will change; Add the material skewness on belt that is transported, load reasons such as weight is inconsistent are taken advantage of in each place, and deviation phenomenon still often has generation.
The purpose of this utility model is invented a kind of device exactly, can in time prevent when deviation phenomenon appears in belt conveyor, and is adjusted.
The utility model is by on the tensioning wheel carrier (12) of load-transfer device, burn-on left support arm (11) and right support arm (7), and left wheel (1) is installed at the other end of left support arm (11), at the other end of right support arm (7) right roller (4) is installed and is realized goal of the invention.
Left support arm of the present utility model (11) and right support arm (7) respectively with the axis normal of tension wheel (8), the distance between the wheel limit of left wheel (1) and right roller (4), more bigger than the fabric width of belt conveyor (2).Fulcrum shaft (9) is equipped with in the centre of tensioning wheel carrier (12), and the other end of fulcrum shaft (9) is connected with the middle of left socle (10) and right support (6).
When belt conveyor (2) when normally moving, tension wheel (8) makes belt conveyor (2) in tension because the weight of self is pushed down belt conveyor (2).Because tension wheel (8) is mounted on the tensioning wheel carrier (12), and tensioning wheel carrier (12) is connected with left socle (10), right support (6) by fulcrum shaft (9), left socle (10), right support (6) are fixed on the feed weigher frame by left support abutment (3) and right support abutment (5) respectively again.So tension wheel (8) can only rotate in the original place, can not do displacement.Because left socle (10) can rotate to left support abutment (3) and right support abutment (5) respectively with right support (6), so tension wheel (8) can be made bob according to the tightness of belt conveyor (2), be in suitable tensioning degree to guarantee belt conveyor (2).During normal operation, the working direction of belt conveyor (2) is vertical with the axis direction of tension wheel (8).At this moment, belt conveyor (2) sideslip can not occur.
When the both sides of belt conveyor (2) degree of tightness occurs when inconsistent because of certain reason, one side of pine (being assumed to the right) kinematic velocity will accelerate, and tight one side (being assumed to the left side) kinematic velocity will be slack-off, at this moment, belt conveyor (2) will be partial to the left side, " sideslip " phenomenon promptly occurs.This phenomenon is sideslip (otherwise then being called sideslip to the right) left.At this moment, the axis of the sense of motion of belt conveyor (2) and tension wheel (8) left side angle occurs less than 90 degree with regard to out of plumb, and the right angle is greater than the phenomenon of 90 degree.Belt conveyor (2) just is partial to the left side, so the pressure between the leftmost edge of belt conveyor (2) and the left wheel (1) strengthens, left wheel (1) is at this moment given tensioning wheel carrier (12) transmission of pressure by left support arm (11), force tensioning wheel carrier (12) to rotate around fulcrum shaft (9), the result of rotation makes the axis direction of tension wheel (8) become vertical with the sense of motion of belt conveyor (2).Thereby belt conveyor (2) has recovered normal operation again.
The utility model is made simple, and is easy for installation, do not need to add in addition power, also do not need manual shift, therefore uses also very convenient, respond well.
Accompanying drawing is a scheme drawing of the present utility model.
Among the figure: 1, left wheel, 2, belt conveyor, 3, left support abutment, 4, right roller, 5, right support abutment, 6, right support, 7, right support arm, 8, tension wheel, 9, fulcrum shaft, 10, left socle, 11, left support arm, 12, the tensioning wheel carrier.
Below in conjunction with accompanying drawing, a non-limiting examples is illustrated.
Left wheel (1) all is that diameter is 40 millimeters a roller with right roller (4), the Edge Distance of two-wheel edge and belt conveyor is 10 millimeters, left side support arm (11) is that length is 300 millimeters steel part with right support arm (7), one end is welded on the tensioning wheel carrier (12), tension wheel (8) is that a diameter is 47 millimeters, the steel wheel that length equates with the fabric width of belt conveyor (2), fulcrum shaft (9) are that a diameter is 16 millimeters a steel axle.Remaining parts all is the parts in the former stretching device.
The utility model is used for the material conveying mechanism of speed governing constant feed weigher, and the material metering precision that is transferred is improved, and feed is accurate.
Claims (1)
1, adjust the device of belt conveyor sideslip, by left support abutment (3), right support abutment (5), left socle (10), right support (6), tensioning wheel carrier (12), tension wheel (8) is formed, and it is characterized in that:
The top middle part of a, tensioning wheel carrier (12) is welded with fulcrum shaft (9), and the other end of fulcrum shaft (9) is installed in the middle part of left socle (10) and right support (6);
