[0002] Existing conveying equipment is widely used in various industrial production processes, with conveyor belts and drive rollers being crucial components. However, traditional rollers are prone to problems such as belt slippage, rapid wear, and short lifespan during use, affecting the stable operation of the equipment and production efficiency. These problems are particularly pronounced under high loads and harsh environments, leading to increased maintenance costs and prolonged equipment downtime.

[0003] For example, Chinese patent CN220148390U discloses a combined ceramic-coated roller. This patent has some shortcomings, such as a complex structure that increases the difficulty of production and installation; the complex structure makes daily maintenance inconvenient and affects production efficiency; and the drive component and locking component have insufficient durability under high load.

[0004] Therefore, an improved roller structure is needed to provide a higher coefficient of friction, longer service life, and better wear resistance to solve the problems existing in the use of traditional rollers. Ceramic-coated rollers not only effectively increase the coefficient of friction and eliminate belt slippage, but also significantly improve the service life of both the roller and the belt, reduce maintenance costs and equipment downtime, and increase production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1 to 6 As shown, this utility model provides a ceramic-coated roller, which includes a roller body 1, a coating body 2 fixed to the surface of the roller body 1, and a plurality of ceramic blocks 3 embedded in the coating body 2. The ceramic blocks 3 are arranged in an array along the outer peripheral wall of the coating body 2, and there is a coating gap between adjacent ceramic blocks 3. At least one ceramic protrusion 30 is provided on the surface of the ceramic block 3, and the ceramic protrusion 30 extends beyond the surface of the coating body 2.

[0030] In one embodiment, the roller body 1 is made of high-strength steel, and two shafts extend from both ends of the roller body 1. The shafts have notches and bearings that connect to the transmission device, providing torque input to the roller body 1. Multiple stepped protrusions are present at the connection between the shafts and the roller body 1 to prevent breakage and collisions on both sides during transmission.

[0031] Ceramic-coated rollers significantly increase the coefficient of friction between the conveyor belt and the drive roller, effectively preventing belt slippage. They also possess superior wear resistance, greatly extending the roller's service life. Furthermore, they extend the overall lifespan of both the belt and the roller, reducing replacement frequency and maintenance costs.

[0032] like Figure 3 As shown, the adhesive groove on the outer surface of the main shaft of the roller body 1 is provided with corrugated ribs or dotted ribs. The corrugated ribs are designed with a wave-shaped structure and are distributed throughout the entire outer surface of the adhesive groove. The dotted ribs are also distributed as small protrusions on the outer surface of the adhesive groove, with each dotted rib arranged in a linear and circular array. These dotted ribs further enhance the bonding force between the roller body 1 and the adhesive coating 2 by providing multi-point support.

[0033] Furthermore, the ceramic block 3 includes a ceramic body 31 and a bonding groove recessed from the lower surface of the ceramic body 31. The ceramic body 31 is made of a high-hardness ceramic material and is embedded in the encapsulated body 2 through the bonding groove. The ceramic body 31 is embedded in the encapsulated body 2, and at least a portion of the encapsulated body 2 adheres to the wall of the bonding groove. The ceramic protrusions 30 and the bonding groove are disposed back-to-back on the ceramic body 31.

[0034] like Figure 4 As shown, the rubber coating 2 is rolled and adhered to the surface of the roller body 1, completely covering the entire surface. The rubber coating 2 is made of a highly wear-resistant and heat-resistant rubber material.

[0035] In one embodiment, the coating body 2 includes two or more coating sheets 20, each coating sheet 20 is fitted with multiple ceramic blocks 3, and the coating sheets 20 are adhered one by one to the surface of the roller body 1 to form an integral coating layer.

[0036] In one embodiment, the overlapping portion of the rubber-coated sheets 20 is stepped and complementary, with adjacent rubber-coated sheets 20 at least partially overlapping and adhering. The rubber-coated sheets 20 can be flat or can be in the form of a clamping device with protrusions and adhesive grooves cooperating with each other. The length of the rubber-coated sheets 20 is the same as that of the roller body 1, and its inner diameter is slightly smaller than the maximum outer diameter of the roller body 1.

[0037] Specifically, during installation, the surface of the roller body 1 needs to be cleaned and pre-treated to ensure adhesion. To ensure strong adhesion in the overlapping area, a special compaction tool is used to compact the overlapping parts, ensuring that the adhesive is evenly distributed and firmly adhered. By adhering all the rubber sheets 20 one by one, the entire surface of the roller body 1 is evenly covered by the rubber sheet 2, with no obvious gaps between the rubber sheets 20.

[0038] like Figure 5 and Figure 6 As shown, the encapsulated body 2 includes a left encapsulated body 21 and a right encapsulated body 22, and the ceramic blocks 3 embedded in the left encapsulated body 21 and the right encapsulated body 22 have opposite tilt angles. The surface ceramic blocks 3 of the encapsulated body 2 can take various forms, such as herringbone or rhombus, and are not specifically limited to these.

[0039] In one embodiment, the ceramic block 3 is rectangular, the edges of the ceramic block 3 are distributed parallel to the axis of the roller body 1, and the ceramic block 3 is fitted along the outer peripheral wall of the coating body 2.

[0040] In one embodiment, the roller body 1, the rubber-coated body 2, and the ceramic block 3 are a three-in-one structure of ceramic, rubber, and steel plate, or a two-in-one structure of ceramic and rubber, integrally vulcanized. The ceramic roller coating is achieved by vulcanizing resistant ceramic sheets within the rubber in a specific arrangement, and then attaching them to the roller surface.

[0041] The ceramic block 3 can be divided into two shapes: spherical and planar. The impact surface with ceramic protrusions 30 is a spherical composite ceramic liner, while the other wear surfaces are planar composite ceramic liners.

[0042] In one embodiment, the ceramic blocks 3 are rhomboid in shape, with the line connecting the two acute angles of the ceramic blocks 3 parallel to the axis of the roller body 1, and the ceramic blocks 3 are fitted along the outer peripheral wall of the coating body 2. The arrangement direction of the ceramic blocks 3 is radial and axial along the roller body 1.

[0043] In one embodiment, the ceramic bumps 30 are configured as spherical bumps 300, and the number can be three or more. The spherical bumps 300 are located on the upper surface of the ceramic block 3, and their distribution on the upper surface can be rectangular or annular, etc., and the curvature of the sphere is not limited.

[0044] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of the present invention are indicated by the following claims.
