No power roller in the belt conveyor application field is very wide, is an important component of components. Roller is an important part of belt conveyor. It has many kinds and large quantity and can support the conveyor belt and material weight. Compared with the traditional screw conveyor with shaft, the conveyor adopts the design without center shaft and uses the whole steel screw push material with certain flexibility, so it has the following outstanding advantages: strong winding resistance. No power roller plays a supporting and bearing role in the conveying equipment, which is mainly composed of a number of no power roller and conveyor belt combined, and can be used according to the different occasions, some belt conveyor chance is very long, and by several paragraphs of combination, the adjacent frame two there is a drop, when the upper section of the conveyor belt material falls to the beginning of the lower section, Due to the influence of the dead weight and speed of materials, the existing technology can realize the cushioning effect between the belt and the roller through the idler mechanism and several buffer rubber rings set on both sides of the idler, which can protect the rubber conveyor belt and the conveyor idler against the external impact to a certain extent. However, it has been found in the field application in the industry that, This structure can not fundamentally solve the conveyor belt and roller between the long-term work of the vulnerable problem.
We can solve the above technical problems by protecting the conveyor belt and groove roller in the complex material impact impact, A limit to reduce the impact of external force of A new conveyor buffer roller mechanism. In the industry, the buffer roller structure of belt conveyor developed by A mainly includes the conveyor bracket, the side roller on both sides of the middle roller. Its characteristic is that the engineer will be the middle roller at both ends of the shaft and the adjacent side roller shaft is hinged, fixed on the buffer of the belt conveyor beam, roller frame by the beam and the beam at both ends of the hinged side roller bracket, the side roller bracket between the movable parts are connected, and the assembled buffer is composed of a buffer shaft, buffer shaft sleeve and spring. After the lower end passes through the low hole of the shaft sleeve fixed on the beam, the preload is adjusted to the appropriate, and the buffer shaft is locked with two nuts. The step is fixed on the buffer shaft, whose diameter is greater than the diameter of the pressure spring and less than the inner diameter of the shaft sleeve. The movable connection adopted by this mechanism is composed of the nut, the spring pad and the threaded pin through the hole of the side roller support. One end of the thread pin is matched with the shaft pin of the side roller to ensure the realization of the functional structure of the whole component. Compared with the traditional screw conveyor with shaft, the conveyor adopts the design without center shaft and uses the whole steel screw push material with certain flexibility, so it has the following outstanding advantages: strong winding resistance.
The development and design of the above structure, in the field application under the impact of the material, the conveyor belt, the middle roller and the two sides of the roller flexible downward pressure, can overcome the hard collision and, so as to effectively protect the conveyor belt and a number of rollers in the service life, this structure is very suitable for the existence of large Angle drop belt conveyor at the beginning of the application of the field environment. No power roller technology finishing and release.
