[0020] Specifically, a U-shaped structure is disposed transversely on the mounting frame 5 , and upper and lower inner walls of the mounting frame 5 are movably fitted with upper and lower side surfaces of the movable plate 7 .

[0021] In this embodiment, the mounting frame 5 facilitates the installation and movement of the driving mechanism 6 and the moving plate 7. The moving plate 7 can stably move along the inner wall of the mounting frame 5, making the moving process of the moving plate 7 more stable.

[0022] Specifically, the driving mechanism 6 includes an electric linear module 601, a transmission rod 602, a hinge 603 and a connecting rod 604. The electric linear module 601 is provided with two upper and lower mirror images, and the upper and lower electric linear module 601 screw rods are connected by the transmission rod 602. The electric linear module 601 is respectively fixedly installed on the upper and lower side walls of the mounting frame 5. The front and rear sides of the slide of the electric linear module 601 and the upper part of the movable plate 7 are provided with hinges 603, and the front and rear corresponding hinges 603 are connected by a connecting rod 604.

[0023] In this embodiment, the up and down and front and back electric linear modules 601 use synchronous motors. The slide of the electric linear module 601 drives the connecting rod 604 to move through the hinge 603, and the connecting rod 604 drives the moving plate 7 to move back and forth.

[0024] Specifically, the outer surface of the slide of the electric linear module 601 is a rectangular structure, and the slide of the electric linear module 601 is movably fitted to the inner wall of the mounting frame 5 .

[0025] In this embodiment, the slide table of the electric linear module 601 moves stably up and down along the inner wall of the mounting frame 5 .

[0026] Specifically, the adjustment mechanism 8 includes a trapezoidal block 801, an inclined block 802, a slide groove 803 and a slider 804. The trapezoidal block 801 is fixedly mounted on the movable plate 7. The fixed roller assembly 2 and the movable roller assembly 3 corresponding to the trapezoidal block 801 are both provided with inclined blocks 802.

[0027] In this embodiment, when the trapezoidal block 801 moves toward the mounting frame 5, the distance between the left and right oblique blocks 802 becomes smaller. Conversely, when the trapezoidal block 801 moves toward the mounting frame 5, the distance between the left and right oblique blocks 802 becomes larger.

[0030] When in use, the movable roller assembly 3 is driven to move left and right along the slide rail 9 by the piston of the hydraulic cylinder 4, and at the same time, the slide table of the electric linear module 601 in the driving mechanism 6 drives the connecting rod 604 to move through the hinge 603, and the connecting rod 604 drives the movable plate 7 to move forward and backward, and the movable plate 7 drives the trapezoidal block 801 in the adjustment mechanism 8 to move forward and backward, and the trapezoidal block 801 moves toward the mounting frame 5, so that the distance between the left and right oblique blocks 802 becomes smaller, that is, the distance between the fixed roller assembly 2 and the movable roller assembly 3 becomes smaller, and vice versa. When the trapezoidal block 801 moves toward the mounting frame 5, the distance between the left and right oblique blocks 802 becomes larger, and the distance between the fixed roller assembly 2 and the movable roller assembly 3 is deformed. The oblique block 802 moves along the slide groove 803 on the trapezoidal block 801 through the slider 804, so that the left and right movement process of the left and right oblique blocks 802 is stable, and the roller gap between the fixed roller assembly 2 and the movable roller assembly 3 can be adjusted without stopping the machine, which greatly improves work efficiency. In addition, mechanical operation is adopted without manual operation, which greatly improves safety.

[0031] In summary, the roller gap adjustment device of the roller press can adjust the roller gap between the fixed roller assembly 2 and the movable roller assembly 3 without stopping the machine, which greatly improves work efficiency, and adopts mechanical operation without manual operation, which greatly improves safety.
