AI Technical Summary
In the existing technology, the opening degree of the drawing roller needs to be adjusted from both ends separately, which is cumbersome and can easily lead to insufficient parallelism between the upper and lower rollers and inconsistent adjustment ranges.
A drafting roller opening adjustment mechanism was designed. Through a knob, transmission components and a linkage gear system, the upper and lower rollers can be adjusted synchronously. By using a bevel gear connection between the connecting rod and the rotating rod, rotating the knob can drive the upper and lower rollers to move simultaneously, and the linkage gear and rack ensure synchronous action.
It enables rapid and synchronous adjustment of the upper and lower rollers, ensuring consistent opening adjustment between them, avoiding positional deviation, and improving the accuracy and efficiency of adjustment.
