In an embodiment of the present invention, the height coarse adjustment unit 3 includes:
the adjusting groove 31 is formed in the upper portion of the guide roller fixing seat 2, and the shaft head 11 penetrates through the adjusting groove 31;
the adjusting cushion block 32 is arranged between the bottom of the adjusting groove 31 and the lower surface of the shaft head 11;
and the locking bolt 33 is threaded on the guide roller fixing seat 2, and the bottom of the locking bolt 33 is abutted to the upper surface of the shaft head 11.
In this embodiment, through changing the adjustment cushion 32 of different thickness, then, rotatory locking bolt 33 locking spindle nose 11, just can adjust guide roller 1 relative with the height of guide roller fixing base 2 to accomplish the high coarse adjustment of guide roller 1, its regulation is simple and convenient.
In an embodiment of the present invention, the upper surface and the lower surface of the shaft head 11 are flat surfaces. Thus, the contact area of the stub shaft 11 with the setting block 32 and the locking bolt 33 can be increased, so that the structural stability can be improved.
In an embodiment of the present invention, the height fine adjustment unit 4 includes:
a fixed bracket 44;
the inclined sliding block 41 is horizontally and slidably arranged on the fixed bracket 44, the upper surface of the inclined sliding block 41 is provided with a first inclined surface, the lower surface of the guide roller fixing seat 2 is provided with a second inclined surface, and the first inclined surface is in contact with the second inclined surface;
