Belt conveyor roller with anti-deviation self-adaptive correction function
Technical Field
The invention belongs to the technical field of mechanical equipment, and relates to a belt conveyor roller with an anti-deviation self-adaptive correction function.
Background
The deviation of the conveying belt refers to the phenomenon that the conveying belt runs abnormally due to the deviation of a conveying central line from the central line of the conveyor in the running process of the belt conveyor. According to the requirements of relevant national technical specifications, the belt conveyor is allowed to exceed the left and right sides of the end surface of the roller by +0.05B (B is the width of the conveying belt) in operation.
At present, the deviation rectifying modes of the belt conveyor of the domestic small factory mainly comprise the following three modes, and the deviation rectifying modes have some problems more or less. The utility model provides a, take supplementary side roller anti-running device of curve dish, theory of operation is when the belt takes place the skew to cylinder one end, and the curve dish of cylinder side produces thrust to the belt and makes the belt return to just, and the problem is that the belt breaks easily or splits, reduces the life of belt to difficult maintenance when breaking down. The second is that manual adjustment cylinder support height, and the theory of operation is through the manual work raise the cylinder support skew opposite side, makes the left and right sides have the difference in height, and the belt warp because of producing and appears tension and impel the belt self-correction, and the shortcoming consumes the manpower, and work efficiency reduces. The last one is that the material position is thrown in manual adjustment, through manual adjustment material position during throwing the material, makes the material be in on the belt central line, consequently the even difficult off tracking phenomenon that takes place of atress about the belt, but also has some problems, for example uses manpower resources in a large number and makes efficiency reduce, and economic benefits receives the suppression.
Disclosure of Invention
The invention aims to provide a belt conveyor roller with an anti-deviation self-adaptive correction function, which solves the problem of belt deviation caused by lateral component force perpendicular to the moving direction of a conveying belt due to unbalanced stress in the running process of the conveying belt.
The technical scheme includes that the belt conveyor roller with the anti-deviation self-adaptive correction function comprises a fixed main shaft, an outer shaft sleeve and a roller sleeve, wherein the fixed main shaft, the outer shaft sleeve and the roller sleeve are sequentially arranged from inside to outside on the same axis, end covers are arranged at two ends of the roller sleeve, two ends of the fixed main shaft penetrate through the end covers on the corresponding sides and extend outwards, a groove is formed in the middle of the fixed main shaft, an adjusting shaft perpendicular to the axis of the fixed main shaft is arranged in the groove of the fixed main shaft, and the adjusting shaft extends out of the groove and is fixedly connected with the outer shaft sleeve.
The present invention is also characterized in that,
the outer shaft sleeve is sleeved in the middle of the fixed main shaft, and the adjusting shaft penetrates through the outer shaft sleeve and is fixedly connected with the outer shaft sleeve through a screw a.
The adjusting shaft is a stepped shaft, a shoulder is arranged on the portion, located in the groove, of the adjusting shaft, the shape of the shoulder is matched with that of the groove, the adjusting shaft is not in contact with the fixed main shaft, a thrust bearing is arranged on the shoulder of the adjusting shaft, and the thrust bearing is located between the adjusting shaft and the fixed main shaft.
Two flanges are further sleeved on the fixed main shaft and are respectively positioned on two sides of the outer shaft sleeve, and the two flanges are respectively and fixedly connected with two end faces of the outer shaft sleeve through screws b.
The flange is the step shaft appearance, all is provided with angular contact bearing on the shoulder of flange, and angular contact bearing is located between flange and the cylinder cover.
The roller sleeve is fixedly connected with the end cover through a screw c.
The invention has the beneficial effects that:
the belt conveyor roller with the anti-deviation self-adaptive correction function has the advantages of simple and compact structure and flexible and convenient use; the efficiency of the roller is kept the same as that of the original roller in normal operation, and when the belt moves and deviates, the roller generates torque around an adjusting shaft with the center vertical to the main shaft through unbalance of stress on two sides of the roller, so that the roller deflects around the shaft, the tension of the belt is changed, and the automatic correction of the belt is finally realized; the belt abrasion is reduced to a certain extent, the labor cost is reduced, and the production efficiency is improved.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention relates to a belt conveyor roller with a deviation-resisting self-adaptive correction function, which comprises a fixed main shaft 3, an outer shaft sleeve 9 and a roller sleeve 5, wherein the fixed main shaft 3, the outer shaft sleeve 9 and the roller sleeve 5 are sequentially arranged from inside to outside on the same axis, two ends of the roller sleeve 5 are fixedly connected with end covers 1 through screws c7, two ends of the fixed main shaft 3 penetrate through the end covers 1 on the corresponding sides to extend outwards, two ends of the fixed main shaft 3 are fixed ends, the middle part of the fixed main shaft 3 is provided with a groove, an adjusting shaft 10 vertical to the axis of the fixed main shaft 3 is arranged in the groove of the fixed main shaft 3, and the adjusting shaft 10 extends out of the groove and is.
