DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-7 As shown, an embodiment of the utility model provides a curved roller skin structure of a double-roller machine, including roller skin 1 and roller skin 2. The outer wall of roller skin 1 is integrally formed with evenly distributed convex rings 4, and a groove 3 is naturally formed between two adjacent convex rings 4. The outer wall of roller skin 2 is integrally formed with evenly distributed convex rings 5, and a groove 26 is naturally formed between two adjacent convex rings 25. The convex ring 14 is adapted to the groove 26, and the convex ring 25 is adapted to the groove 13. Roller skin 1 includes roller skin unit 14 and roller skin unit 2 15, and roller skin 22 includes roller skin unit 3 18 and roller skin unit 4 19.

[0025] Specifically, in this embodiment, it includes roller skin 1 and roller skin 2. The outer wall of roller skin 1 is integrally formed with evenly distributed convex rings 4. A groove 3 is naturally formed between two adjacent convex rings 4. The width of convex ring 14 is greater than the width of groove 3. The outer wall of roller skin 2 is integrally formed with evenly distributed convex rings 5. A groove 6 is naturally formed between two adjacent convex rings 5. The width of groove 6 is greater than the width of convex ring 5. Convex ring 14 is matched with groove 6. Convex ring 25 is matched with groove 3. The surfaces of roller skin 1 and roller skin 2 form a curved surface structure. When the stone is crushed, it will enter the gap between roller skin 1 and roller skin 2 for crushing. When the roller skin is a smooth cylindrical surface, the stone will be moved toward the roller skin due to factors such as the inclination of the installation of the roller machine and mechanical vibration. One end is offset, which causes uneven wear of the roller skin. Therefore, the curved roller skin can solve the problem of stone offset between the two roller skins. Roller skin 1 includes roller skin unit 14 and roller skin unit 2 15. Roller skin 2 includes roller skin unit 3 18 and roller skin unit 4 19. Roller skin unit 14 and roller skin unit 2 15 are connected to form roller skin 1, so that roller skin 1 can be assembled from small-volume roller skin unit 14 and roller skin unit 2 15, which makes it easier to process the roller skin. Because the larger the volume of the roller skin, the higher the performance requirements of the equipment for processing the roller skin, and the greater the processing difficulty, reducing the processing volume of the roller skin, thereby reducing the processing difficulty of the roller skin. Similarly, roller skin 2 is composed of roller skin unit 3 18 and roller skin unit 4 19.

[0026] The utility model provides a curved roller skin structure of a double-roller machine, in which a wider convex ring 14 on the roller skin 1 cooperates with a wider groove 26 on the roller skin 2, and at the same time a narrower groove 3 on the roller skin 1 cooperates with a narrower convex ring 25 on the roller skin 2, so that the curved roller skin of the double-roller machine forms a structure in which one narrow and one wide fit together, so that the stone is more evenly fed, and can effectively prevent the stone from deviating to one side, so that the stone material will not deviate, and at the same time, the effect of uniform wear of the roller skin of the double-roller machine is achieved.

[0027] In another embodiment provided by the utility model, a pin hole 17 is opened on the outer wall of the side where the roller skin unit 14 and the roller skin unit 2 15 are close to each other, and a pin column 16 is inserted into the interior of the pin hole 17, and the roller skin unit 14 and the roller skin unit 2 15 are assembled through the pin column 16; a pin hole 2 10 is opened on the outer wall of the side where the roller skin unit 3 18 and the roller skin unit 4 19 are close to each other, and a pin column 20 is inserted into the interior of the pin hole 20, and the roller skin unit 3 18 and the roller skin unit 4 19 are assembled through the pin column 20.

[0028] Furthermore, a central cavity 11 is opened inside the roller skin 1 and the roller skin 2, and a wear-resistant layer 9 is provided on the outer wall of the roller skin 1 and the roller skin 2. The wear-resistant layer 9 is a carburized layer. The roller skin is carburized, and the roller skin is increased to withstand wear, alternating contact stress and impact load. The surface hardness, wear resistance, contact fatigue strength and corrosion resistance of the roller skin are greatly improved; the inner wall of the central cavity 11 is welded with a connecting plate 7 distributed symmetrically with the center, and a connecting hole 8 is opened on the outer wall of one side of the connecting plate 7. The connecting plate 7 and the connecting hole 8 are structures used for installing and fixing the roller skin; a retaining ring 12 is integrally formed on the outer wall of one side of the roller skin 1, and a retaining ring 2 13 is integrally formed on the outer wall of the side of the roller skin 1 away from the retaining ring 12. The retaining ring 12 and the retaining ring 2 13 form a blocking structure at both ends of the roller skin 1, so that the overall width of the roller skin 1 is greater than that of the roller skin 2, so that the stones at both ends of the roller skin 1 can also be fully crushed.

[0029] Working principle: The wider convex ring 14 on the roller skin 1 cooperates with the wider groove 26 on the roller skin 2, and the narrower groove 3 on the roller skin 1 cooperates with the narrower convex ring 25 on the roller skin 2, so that the curved roller skin of the roller machine forms a narrow and wide structure that fits together, so that the stone is more evenly fed, and can effectively prevent the stone from deviating to one side, so that the stone material will not deviate, and at the same time achieve the effect of uniform wear of the roller skin of the roller machine; the roller skin unit 14 and the roller skin unit 2 15 are connected to form the roller skin 1, so that the roller skin 1 can be assembled from the small-volume roller skin unit 14 and the roller skin unit 2 15, thereby making the roller skin easier to process; the two ends of the pin column 16 are respectively inserted into the pin hole 17 of the roller skin unit 14 and the roller skin unit 2 15, so that the roller skin unit 14 and the roller skin unit 2 15 are more convenient to connect and assemble.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
