[0002] Roller presses are mainly used in cement manufacturing, metallurgy, mining and other industries. During long-term use, the roller shell surface and side edges are severely worn. Therefore, the roller shell and side edges of the roller press are required to have high hardness, strength and wear resistance.

[0003] Currently, alloy studs are embedded on the surface of the roller sleeve to ensure the service life of the roller surface. However, there has been no effective method to fix the side of the roller sleeve, resulting in a lower service life than other parts of the roller sleeve, affecting the service life of the entire roller sleeve. In addition, replacement of the roller sleeve requires a long downtime, large-scale replacement, and increased economic costs.

[0004] At present, the side protection structure of the roller sleeve is mainly surfacing with wear-resistant materials. The surfacing layer of wear-resistant materials is prone to fall off during use, and replacement requires long-term maintenance, which increases maintenance costs. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] A typical implementation of the present invention is as follows: Figure 1 As shown, a roller sleeve side protection structure of a roller press includes a wear-resistant base plate 1. The wear-resistant base plate 1 is fan-shaped. Multiple wear-resistant base plates 1 can be combined into a circular ring structure to cover the side of the roller sleeve, protect the side of the roller sleeve, and improve the wear resistance of the side of the roller sleeve.

[0031] like Figure 2 As shown, a plurality of U-shaped grooves 6 are provided on the top of the wear-resistant substrate 1, and the plurality of U-shaped grooves 6 are evenly arranged along the length direction of the top surface of the wear-resistant substrate 1. The two ends of the U-shaped groove 6 pass through the side walls of the wear-resistant substrate 1. The upper width of the U-shaped groove 6 is smaller than the lower width, so that the U-shaped groove 6 forms a structure that is narrow at the top and wide at the bottom. A plurality of alloy edge nails 2 are provided above the wear-resistant substrate 1, and the plurality of alloy edge nails 2 are arranged side by side along the top surface of the wear-resistant substrate 1, and the plurality of alloy edge nails 2 are arranged corresponding to the plurality of U-shaped grooves 6. The length of the alloy edge nail 2 is the same as the width of the wear-resistant substrate 1, so that the end faces of the alloy edge nails 2 are flush with the side walls of the wear-resistant substrate 1. Figure 3 As shown, a U-shaped protrusion 7 is provided on the bottom surface of the alloy edge nail 2, and the U-shaped protrusion 7 is adapted to the U-shaped groove 6, so that the U-shaped protrusion 7 can be inserted into the U-shaped groove 6 from both ends of the U-shaped groove 6. Since the U-shaped groove 6 is a structure that is narrow at the top and wide at the bottom, when the U-shaped protrusion 7 at the bottom of the alloy edge nail 2 is inserted into the U-shaped groove 6, the alloy edge nail 2 can be prevented from falling off from the U-shaped groove 6. By arranging multiple alloy edge nails 2 on the top surface of the wear-resistant base plate 1, the roller surface at the side position of the roller sleeve of the roller press is protected.

[0032] A plurality of mounting holes 4 are provided on the side of the wear-resistant base plate 1. The plurality of mounting holes 4 are located on the upper part of the side of the wear-resistant base plate 1. The plurality of mounting holes 4 are evenly arranged. Alloy side nails 3 are provided in the mounting holes 4. The ends of the alloy side nails 3 protrude from the side of the wear-resistant base plate 1. During installation, the side with the alloy side nails 3 is facing outward. By providing a plurality of alloy side nails 3 on the side of the wear-resistant base plate 1, the side end face of the roller sleeve is protected.

[0033] The side of the wear-resistant base plate 1 is also provided with multiple bolt holes 5, which are evenly arranged on the lower part of the side of the wear-resistant base plate 1. The side protection can be installed on the roller sleeve by bolts, and multiple wear-resistant base plates 1 are combined into a circular ring structure and fixed to the side of the roller sleeve of the roller press by bolts, thereby improving the side wear resistance and greatly extending the service life of the roller sleeve.

[0034] Furthermore, the alloy edge nails 2 and the alloy side nails 3 are fixed to the wear-resistant base plate 1 by welding or gluing, forming an integrated structure with the wear-resistant base plate 1 .

[0037] like Figure 5 As shown, a groove 8 is provided on the top of the wear-resistant substrate 1, and the groove 8 extends along the length direction of the top surface of the wear-resistant substrate 1. A plurality of alloy edge nails 2 are arranged in the groove 8, and the plurality of alloy edge nails 2 are arranged along the length direction of the groove 8. The width of the alloy edge nail 2 is the same as the width of the groove 8, so that the two sides of the alloy edge nail 2 are respectively in contact with the side walls of the groove 8, and the height of the alloy edge nail 2 is the same as the depth of the groove 8, so that the top of the alloy edge nail 2 does not protrude from the top of the groove 8. By arranging the groove 8 on the top of the wear-resistant substrate 1 and arranging a plurality of alloy edge nails 2 in the groove 8, the roller surface at the side position of the roller sleeve of the roller press is protected.

[0038] A plurality of mounting holes 4 are provided on the side of the wear-resistant base plate 1. The plurality of mounting holes 4 are located on the upper part of the side of the wear-resistant base plate 1. The plurality of mounting holes 4 are evenly arranged. Alloy side nails 3 are provided in the mounting holes 4. The ends of the alloy side nails 3 protrude from the side of the wear-resistant base plate 1. During installation, the side with the alloy side nails 3 is facing outward. By providing a plurality of alloy side nails 3 on the side of the wear-resistant base plate 1, the side end face of the roller sleeve is protected.

[0039] The side of the wear-resistant base plate 1 is also provided with multiple bolt holes 5, which are evenly arranged on the lower part of the side of the wear-resistant base plate 1. The side protection can be installed on the roller sleeve by bolts, and multiple wear-resistant base plates 1 are combined into a circular ring structure and fixed to the side of the roller sleeve of the roller press by bolts, thereby improving the side wear resistance and greatly extending the service life of the roller sleeve.
