[0038] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] like Figures 1 to 6 As shown, a device for adjusting the height of an upper roller 1 comprises:

[0040] Top plate 8, top plate 8 is fixedly connected to upper frame 2, and the lower end surface of top plate 8 is an inclined surface; first adjustment plate 5, the upper end surface of first adjustment plate 5 is an inclined surface, the upper end surface of first adjustment plate 5 is fitted with the lower end surface of top plate 8, and the first adjustment plate 5 can be movably connected to upper frame 2; second adjustment plate 4, the upper end surface of second adjustment plate 4 is fitted with the lower end surface of first adjustment plate 5, a step structure is arranged on the lower end surface of second adjustment plate 4, and the second adjustment plate 4 can be movably connected to upper frame 2; adjacent step surfaces in the step structure adopt chamfered structure; support block 9, support block 9 is fixedly connected to bearing seat 3 of upper roller 1, and the upper end surface of support block 9 supports the step structure of second adjustment plate 4. The end surfaces on both sides of support block 9 adopt chamfered structure, and the chamfered structure of support block 9 matches the guide structure of the step structure. The difference of the upper end inclined surface of first adjustment plate 5 is greater than the height of each step in the step structure.

[0041] Each bearing seat 3 is fixed with a support block 9, and each support block 9 is correspondingly provided with a first adjustment plate 5, a second adjustment plate 4, and a top plate 8; the two first adjustment plates 5 are connected by a connecting component 6; the two second adjustment plates 4 are connected by a connecting component 6.

[0042] The connecting assembly 6 includes an adjusting tube 601 and a stud 602, wherein the number of the studs 602 is two, one of which has a left-handed thread and is fixedly connected to one of the first adjusting plates 5, and the other stud 602 has a right-handed thread and is fixedly connected to the other first adjusting plate 5; the two ends of the adjusting tube 601 are respectively threadedly connected to the two studs 602.

[0043] Each stud 602 is threadedly connected with a locking nut 604, and the locking nut 604 is pressed against the adjusting tube 601. A plug hole 603 is provided on the side wall of the adjusting tube 601, and the plug hole 603 is convenient for inserting a crowbar to rotate the adjusting tube 601.

[0044] By rotating the adjusting tube 601, the distance between the two first adjusting plates 5 can be adjusted, and the adjustment height of the two bearing seats 3 can be accurately controlled. The installation process is simple. In addition, if the wear amount at both ends of the roller is different during the use of the roller, it is necessary to adjust the height of the two ends of the roller by adjusting the distance between the two first adjusting plates 5.

[0045] The first adjustment plate 5 and the second adjustment plate 4 are respectively provided with a driving assembly 7, and the driving assembly 7 is a hydraulic cylinder. The shells of the two hydraulic cylinders are fixedly connected to the upper frame 2, the output shaft of one hydraulic cylinder is fixedly connected to the first adjustment plate 5, and the output shaft of the other hydraulic cylinder is fixedly connected to the second adjustment plate 4.

[0046] The moving directions of the first adjustment plate 5 and the second adjustment plate 4 are the same; guide plates 401 are fixedly provided on both sides of the second adjustment plate 4, and a guide channel is formed between the two guide plates 401. The guide channel is arranged along the moving direction of the first adjustment plate 5, and the width of the guide channel matches the width of the first adjustment plate 5. The first adjustment plate 5 is located on the inner side of the guide channel. The setting of the guide plate 401 guides the moving process of the first adjustment plate 5 to prevent the first adjustment plate 5 from shaking during the movement.

The sliding column 10 limits the movement of the second adjustment plate 4 and the first adjustment plate 5.

[0048] The width of the top plate 8 matches the width of the guide channel. The top plate 8 is located on the inner side of the guide channel. The top plate 8 guides and limits the movement of the guide channel to prevent the second adjustment plate 4 from sliding during movement.

[0049] The top plate 8, the first adjustment plate 5, the second adjustment plate 4, the support block 9, and the guide plate 401 are all structural parts made of wear-resistant steel, which increases the service life of the device.

[0050] During the working process, when this solution is implemented, the height is adjusted according to the target. The second adjusting plate 4 is moved by the hydraulic cylinder to roughly adjust the height of the upper roller 1. Then the hydraulic cylinder drives the first adjusting plate 5 to move. Under the support of the inclined surface, the height of the upper roller 1 can be accurately adjusted. The adjustment process is convenient and the work efficiency is improved.

[0051] By providing two guide plates 401 to guide the movement of the first adjustment plate 5 and the second adjustment plate 4, and providing the strip-shaped through hole 402 to limit the movement range of the first adjustment plate 5, the stability of the adjustment process is improved.
