Automatic aligning carrier roller set

Abstract

An automatic aligning carrier roller set comprises a vertical roller (1), two side carrier rollers (2), a middle carrier roller (4), a rotary beam (5), a rotary seat (6), a lower transverse beam (7) and a supporting wheel frame (9). The rotary beam (5) and the lower transverse beam (7) are formed by hinging bolts through the rotary seat (6), ejection motion stopping mechanisms (10) capable of enabling the carrier rollers (2) to be braked are welded to the two ends of the rotary beam (5), and each ejection motion stopping mechanism (10) comprises a shifting fork (11) hinged to the vertical roller (1), a rotary shaft (12), a swing shaft (13), an outer supporting column (14), a pull pin (15) and a spring (16) arranged at the small end of the pull pin (15) in a sleeved mode. According to the automatic aligning carrier roller set, when a rubber belt deviates, the automatic aligning carrier roller set has enough driving torque to easily push and rotate a carrier roller set frame, the movement of the automatic aligning carrier roller set is sensitive, the automatic deviation correction function is fully achieved, the effect of preventing the operation of a conveying belt from deviating is obvious, and the ejection type braking mechanisms guarantee the product service life.

Description

technical field [0001] The invention relates to the technical field of belt conveyor components, in particular to an automatic self-aligning roller set. Background technique [0002] During the production and operation of the belt conveyor, the conveying material often leaks due to the deviation of the conveyor belt from the center, which seriously affects the material conveying. The belt of the belt conveyor runs on its rollers with a characteristic: that is, the belt always runs along the axis of the vertical roller, so as long as the roller can be controlled to rotate an angle vertical to the axis of the roller under the plane of the belt, the belt can be controlled. direction. At present, various types of automatic self-aligning rollers on the belt conveyor use the characteristic that the belt runs on the roller. Through the additional power generated by the mechanism using the deviation belt, the roller frame rotates at an angle to achieve alignment of the belt. The p...

Problems solved by technology

However, the little additional power generated by the direct deviation of the tape cannot push the idler frame to rotate around its vertical axis, because the idler frame wants to rotate vertically under the tape, except for the need to overcome the mechanical mechanism inside the mechanism. In addition to frictional resistance, it is also necessary to overcome the frictional resistance caused by the positive pressure of the belt and the material on the roller, the resistance caused by the sag of the belt, the resistance caused by equipment corrosion, dust, falling materials, etc. It is necessary to overcome the resistance caused by the change of the groove angle. The sum of these resistances is far greater than the additional driving force generated by the deviation belt. If there is no action, it will cause the material to spill, wear the conveyor belt, reduce the service life of the conveyor belt and bring safety hazards
