Abstract
A rotating-speed-adjustable pressing wheel assembly relates to the technical field of pressing wheels, and comprises a connecting rod, wherein the connecting rod is provided with a groove, and an idler wheel is sleeved on the groove. The pressing wheel assembly is characterized in that the two side faces of the groove are provided with inwards sunk half-sphere grooves, steel balls are placed in the half-sphere grooves, and the steel balls are abutted against the side faces of the idler wheel. The pressing wheel assembly is simple in structure, reasonable in design, simple and practical and has a good effect, and the steel balls are abutted against the two sides of the idler wheel, so that the effect of fixing the position of the idler wheel is played without influencing the rolling of the idler wheel, and the condition of left and right movement of a pressed object due to inaccurate positioning of the idler wheel caused by the fact that the idler wheel rolls in the groove back and forth is avoided.
