Description

Technical Field

[0001] The utility model relates to the technical field of transportation, in particular to a ceramic rubber coating layer for a roller. Background Art

[0002] The main raw material of a coal preparation plant is coal. After screening and crushing, the coal enters the washing and processing stage. The belt conveyor is the most ideal high-efficiency continuous transportation equipment for a coal preparation plant. It has the advantages of long distance, large capacity, and continuous transportation. It is reliable in operation and has become a key transportation equipment in the production environment of a coal preparation plant. Each belt conveyor is equipped with a certain number of metal rollers. In the past, when the outer surface of the metal roller was coated with a rubber sheet, the coating layer needed to be polished with a grinding wheel when it was ready for use. The process was cumbersome and the construction cost increased. In addition, the contact resistance of the wear-resistant surface of the rubber sheet was small, resulting in a small grip between the roller and the conveyor belt. Under the same load, the belt always maintains a large tension, the belt is seriously worn, and the service life of the belt is reduced. Utility Model Content

[0023] 1 is a ceramic block and 2 is a rubber groove. DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-6 , the technical solution of the utility model is further explained:

[0025] like Figure 1-Figure 6 As shown, a ceramic rubber coating layer for a roller includes a rubber plate, and a semi-vulcanized CN layer is provided on the bonding surface of the rubber plate. That is, the semi-vulcanized CN layer is added on the back side of the rubber plate, i.e., the bonding surface, and the CN layer can enhance the adhesion between the coating layer and the roller, and during on-site construction, there is no need to grind with a grinding wheel, and the coating layer can be directly glued to the roller, thereby reducing the number of processes and the construction cost.

[0026] Specifically, a plurality of ceramic blocks 1 are evenly arranged on the front of the rubber plate. That is, ceramic blocks 1 are arranged in an array and protrude outward on the wear-resistant surface of the rubber plate, i.e., the front of the rubber plate. The ceramic blocks can resist wear, reduce the frequency of downtime and maintenance, and save costs and labor.

[0027] In some embodiments, the ceramic blocks 1 are evenly spaced in a straight line along the axial direction of the rubber plate, and a plurality of linear arrays of ceramic blocks 1 are spaced in parallel in the horizontal direction of the rubber plate. In other words, rows of ceramic blocks are arranged in parallel on the front side of the rubber plate, and the ceramic blocks are arranged in regular rows and columns along the length and width directions of the rubber plate.

[0028] In some embodiments, the ceramic blocks 1 are evenly spaced in an arc shape along the axial direction of the rubber plate, and a plurality of arrays of arc-shaped ceramic blocks 1 are arranged in parallel and spaced in a horizontal direction of the rubber plate. That is, on the front side of the rubber plate, the ceramic blocks are evenly spaced in an arc shape along the length direction of the rubber plate, and the arrays of arc-shaped ceramic blocks are sequentially arranged along the width direction of the rubber plate.

[0029] It should be noted that the ceramic blocks 1 may also be arranged in an S-shape.

[0030] Specifically, rubber grooves 2 for enhancing the grip between the roller and the conveyor belt are provided between adjacent ceramic blocks 1 along the axial direction of the rubber plate. That is to say, a rubber groove having the same length as the rubber plate is provided between two adjacent rows of ceramic blocks, and different materials are discharged under different working conditions. In this embodiment, the description is made under harsh working conditions, i.e., muddy, humid and highly abrasive environments. The rubber grooves bear the responsibility of draining water, discharging mud and other debris during transportation, and can provide a strong grip between the roller and the conveyor belt.

[0031] It should be noted that the width of the rubber groove 2 is greater than the spacing between adjacent ceramic blocks 1 along the axial direction of the rubber plate. In other words, the width of the rubber groove is designed to be greater than the spacing between two adjacent ceramic blocks in a row, so that the rubber groove has a guiding effect, and the closely arranged ceramic blocks enhance the wear resistance.

[0032] Specifically, the spacing between adjacent ceramic blocks 1 along the axial direction of the rubber plate is 8 mm-12 mm, and the width of the rubber groove 2 is 15 mm-18 mm.

[0033] Embodiment 1

[0034] like Figure 1 and Figure 2 As shown, the inner wall of the rubber groove 2 is symmetrically provided with step sections on both sides, and the step sections include a first step and a second step, the first step is connected to the surface of the rubber groove 2, the bottom of the first step is connected to the top of the second step, the bottom of the second step is connected to the bottom surface of the rubber groove 2, and the first step and the second step as a whole form a step section that is continuously downward. That is to say, in this embodiment, the rubber groove is in a step shape with both sides that are continuously downward. When the muddy water flows, the accumulation in the rubber groove is increased, and the contact resistance between the rubber sheet and the muddy water can be increased. At the same time, the debris in the muddy water will be discharged outward in the stepped groove as the drum rotates, and will not be retained to cause the groove to be blocked.

[0035] It should be noted that, in this embodiment, the width of the rubber groove 2 is 15 mm, and the spacing between adjacent ceramic blocks along the axial direction of the rubber plate is 10 mm.

[0036] Embodiment 2

[0037] like Figure 3 and Figure 4 As shown, guide grooves extending toward the inner side of the rubber plate are respectively provided inside the rubber groove 2 near the ceramic blocks 1 on both sides, and the guide grooves are connected with the rubber groove 2. In other words, guide grooves extending downward are also provided on both sides inside the U-shaped rubber groove, and the internal storage volume can be increased by connecting the guide grooves with the rubber groove, thereby increasing the contact resistance of the rubber plate and thus enhancing the gripping force of the roller.

[0038] It should be noted that, in this embodiment, the width of the rubber groove 2 is 18 mm, and the spacing between adjacent ceramic blocks 1 along the axial direction of the rubber plate is 8 mm.

[0039] Embodiment 3

[0040] like Figure 5 and Figure 6 As shown, the cross-sectional shape of the rubber groove 2 is an arc. In other words, the shape of the rubber groove 2 is designed to be an arc to increase the internal storage capacity and enhance the gripping force between the roller and the conveyor belt.

[0041] It should be noted that, in this embodiment, the width of the rubber groove 2 is 16.2 mm, and the spacing between adjacent ceramic blocks 1 along the axial direction of the rubber plate is 10 mm.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
