By the end of the shaft offset extended roller roller can be adjusted under the condition of no stop angle, but the lift roller when the belt supporting lift in supporting the transport roller and the conveyor belt is laborious, movement, may be driven by the friction roller groove conditions appear off the fall. In this paper, a roller bracket with adjustable idler angle is introduced, which can be used to adjust the offset angle of the conveyor belt when the belt conveyor is running normally.
Adjustable roller offset angle roller rack comprises a base frame, a supporting seat, inside the outer supporting seat assembly and sliding holder; outer supporting seat is provided with a conveyor belt along the rail direction, a mounting hole is arranged; sliding seat assembly includes a slide deck, threaded shaft is provided with a slide deck unit, roller installation card the lower part is provided with a sliding groove, a downward opening, is arranged outside of the threaded hole; the slider seat in the slide chute set outside the supporting seat. Screw shaft unit is installed in the mounting hole of the outer supporting seat, and the outer supporting seat rotating pair; screw thread hole and threaded shaft with the slider seat. The thread wheel unit comprises a screw shaft, a spacing sleeve and a limit retainer ring, threaded shaft central thread section is respectively arranged at two ends of the shaft neck, one end is also provided with a collar and shaft. This thread shaft ends of the shaft supported in the mounting hole in the outer supporting seat, by the shoulder, collar, limit set limit etc.. With the above scheme, head rotation shaft screw, screw shaft will drive and screw slide deck movement along the rails.
Using the Bento roller frame, the roller end clamped on the roller supporting seat Bento card slot frame, the other end of the slider holder is clamped in the outer supporting seat on the roller installation slot, adjusting roller offset angle, the head rotation of the tool threaded shaft, the outer support slide deck seat slide along the track, to adjust the bias angle of the roller. The state of the idler after adjusting the offset angle.
The utility model can be used for a common groove shaped roller frame, and can also be used for a deep groove angle supporting roller frame and a lower supporting roller frame. Using the adjustable supporting roller rack and the bias angle of belt conveyor, only rotating screw shaft can realize stepless roller offset angle without stopping the regulation, avoids from a card slot to move to another slot, without lifting the conveyor belt, no supporting risk roll off, making the regulation more efficient, energy saving, safety.
