[0051] To further illustrate the specific adjustment process of the roll gap opening gap provided by the roll gap opening gap adjustment of the present invention, the present invention also provides a roll gap opening gap adjustment method, which uses the aforementioned roll gap opening gap adjustment device 1 for adjustment, comprising:

[0052] Installing two rollers 2 to be adjusted and the roller gap opening gap adjustment device based on a preset transverse center line 10 and a longitudinal center line 9;

[0053] Connecting an adjustment component to the roller gap opening gap adjustment device;

[0054] The roller gap opening gap adjusting device is driven by the adjusting component to adjust the roller gap opening gap between the two rollers 2 .

[0055] Specifically, the installation of the two rollers 2 to be adjusted based on the preset transverse center line 10 and longitudinal center line 9 includes: installation of the track 4 and the rollers 2, and installation of the roller gap opening gap adjustment device.

[0056] The installation of the track 4 and the roller 2 includes: laying the track 4 based on the transverse center line 10 and the longitudinal center line 9, then slidingly connecting the pulley 3 on the track 4, and slidingly connecting the bearing seat 2.1 under the two rollers 2 to the track 4 through the pulley 3.

[0060] Align the center line of the adjusting body 1.6, the center line of the bearing seat 2.1 and the longitudinal center line 9;

[0061] Adjust the first worm 1.1 so that the lengths of the portions of the countersunk holes 1.5 at both ends of the second worm 1.2 exposed from the housing 1.7 are equal;

[0062] The distance between the bearing seats 2.1 is calculated according to the gap of the roller gap opening 11, and the two adjusting bodies 1.6 are adjusted based on the distance between the two bearing seats 2.1 so that the total length of the second worm 1.2 (the distance between the ends of the two adjusting bodies 1.6) is equal to the distance between the two bearing seats 2.1; and the adjusting body 1.6 is locked on the countersunk hole 1.5 with a locking ring 1.4 to match the roller gap opening.

[0068] It should be noted that before controlling the second worm 1.2 to drive the two bearing seats 2.1 to move their positions through the connecting rod 7, it is necessary to first use the hydraulic cylinder 5 to press the bearing seat 2.1 against the adjusting body 1.6 of the second worm 1.2, and then rotate the input connecting rod 7 of the steering gear 8 to move the second worm 1.2 to change the position of the bearing seat 2.1; and, in the specific adjustment process, it is necessary to use the lateral center as a reference to synchronously move the roller gap opening so that the center of the roller gap opening coincides with the lateral center.

[0069] According to the above specific embodiments, the roller gap opening gap adjustment device and adjustment method provided by the present invention have at least the following advantages:
