Function description: Spiral conveyor is mainly used for transmitting pipes spirally in pipe external coating production line. Its function conform to the pipe external FBE, PE, PP coating and winding process requirements, which is characterized by large transmission torque, precise pitch, high speed adjustment on site, and small center offset.

Dual tire roller conveyor include slid-type and pitch adjustment type; Slide-type spiral conveyor has the advantages of constant pipe bottom height, wheel track stepless adjustment, integrated assembly and easy installation.Pitch adjustable type spiral conveyor adopt ratchet adjustment; Two tire wrap angle is greater than 60 degrees, use the rod to connect between wheels, the rod is adjustable, ends of rod use the rod end joint bearing to connect, which ensure the simplicity and unity of tire angle adjustment, and make sure the smooth operation of the conveying line; The two mating surface between conveying wheel base and slide block is equipped with 1 ~ 2 mm ptfe sandwich, which is simple and save effort when adjusting the spacing between the wheels; the control accuracy in the control wheel set place are equipped with scale, in order to observe. After the adjustment the conveying line are locked with locking device, and ensure the control device can be taken down out.
