In this embodiment, as preferred, the two sides of the U-shaped through hole 11 are both extended outward to form the relief opening 15, so that the portion of the pinch roller mounting plate 1 located outside the U-shaped through hole 11 is deformed more easily under stress, and the magnitude of the required force during the angular adjustment is reduced.
In the above structure, the pinch roller mounting portion 12 is provided with a first mounting hole 13, and the pinch roller mounting plate 1 is provided with a first adjusting hole 14.
The adjusting sheet 2 is integrally formed by a fixing part 21, a vertical connecting part 22 and an adjusting part 23 to form a bent structure, namely, the fixing part 21 and the adjusting part 23 are respectively positioned at the upper right side and the lower left side of the vertical connecting part 22, wherein a second mounting hole 24 is formed on the fixing part 21, and a second adjusting hole 25 is formed on the adjusting part 23; the first mounting hole 13 and the second mounting hole 24 correspond to each other, and the first adjustment hole 14 and the second adjustment hole 25 correspond to each other. The upper surface of the adjusting sheet 2 is provided with a spherical groove 26 in the peripheral area of the second adjusting hole 25, and the second adjusting hole 25 is positioned in the middle of the spherical groove 26; correspondingly, the lower surface of the adjusting sheet 2 is provided with a spherical bulge 27; when the adjusting sheet 2 is processed, the spherical groove 26 and the spherical bulge 27 can be formed in one step, and the processing is simple.
The adjusting bolt assembly comprises an adjusting bolt 3, an upper gasket 4 and a lower gasket 5, wherein the adjusting bolt 3 comprises a nut 31, a bolt body 32 and a middle retaining ring 33, the nut 31 is integrally arranged at one end of the bolt body 32, and a hexagon socket is inwards arranged on the end surface of the nut 31. The middle retaining ring 33 is disposed on the middle outer circumferential surface of the bolt 32, and the middle retaining ring 33 may be integrally formed with the bolt 32 or may be screwed to the bolt 32.
The part above the middle baffle ring 33 (i.e. the end of the bolt body far away from the nut) is penetrated and installed in the first adjusting hole 14 of the pinch roller mounting plate 1 and is matched with the thread, the part between the middle baffle ring 33 and the nut 31 on the bolt body 32 is penetrated and installed in the second adjusting hole 25, so that the adjusting part 23 is positioned between the middle baffle ring 33 and the nut 31, and the upper gasket 4 and the lower gasket 5 are respectively tightly attached and installed above and below the adjusting part 23. Specifically, the lower surface of the upper pad 4 is a convex spherical surface matching the spherical groove 26, and the upper surface of the lower pad 5 is a concave spherical surface matching the spherical protrusion 27.
