Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying equipment technology, specifically to a ceramic wear-resistant roller. Background Technology
[0002] Ceramic wear-resistant rollers are key equipment components widely used in industries such as mining, power, building materials, and metallurgy. They are mainly used for conveying bulk materials. Their core advantage lies in the introduction of ceramic materials, which significantly improves the wear resistance, corrosion resistance, and service life of the roller surface, thereby reducing equipment downtime maintenance costs.
[0003] A search revealed a utility model patent in China, CN210762797U, which discloses an impact-resistant and wear-resistant ceramic rubber roller. The roller includes a connecting shaft, a roller body fixedly connected to the outer surface of the connecting shaft, an impact-resistant layer fixedly connected to the outer surface of the roller body, a slot inside the roller body, and a locking block fixedly connected to the side of the impact-resistant layer adjacent to the roller body. This impact-resistant and wear-resistant ceramic rubber roller, by providing an impact-resistant layer, gives the roller a certain degree of impact resistance, and the impact-resistant layer is made of rubber.
[0004] As mentioned above, the ceramic blocks in the outer rubber coating of ceramic wear-resistant rollers are usually embedded through a vulcanization process. However, rollers are easily subjected to significant stress in the working environment. Therefore, as the usage time increases, the ceramic blocks will gradually detach from the rubber coating due to stress, thus affecting the use. At this time, replacement is required, and there is room for improvement in terms of insufficient service life. Utility Model Content
[0005] The purpose of this invention is to provide a ceramic wear-resistant roller to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a ceramic wear-resistant roller, comprising a metal cylinder, wherein two rubber coating layers are bonded to the outside of the metal cylinder, and the two rubber coating layers completely cover the outer surface of the metal cylinder; a plurality of anti-slip components are installed inside each of the two rubber coating layers; the anti-slip components include a vulcanized ceramic block embedded inside the rubber coating layer, and the end of the ceramic block away from the metal cylinder extends out of the rubber coating layer; an extension head is coaxially fixed to the outer wall of the end of the ceramic block near the metal cylinder; and a limiting groove adapted to the extension head is formed on the outer surface of the metal cylinder.
[0007] The metal cylinder also provides leverage for the ceramic block, ensuring that it does not shift excessively due to excessive stress during use. This effectively prevents the ceramic block from detaching from the coating layer. During assembly, simply align the extension head of the ceramic block inside the coating layer with the limiting groove on the surface of the metal cylinder. The limiting groove provides a positioning effect, preventing the coating layer from shifting and ensuring a smooth coating process. When the roller is in use, if the ceramic block tends to shift due to stress, its extension head will also tend to move. The limiting groove restricts the position of the extension head, effectively preventing the ceramic block from detaching from the coating layer due to repeated movement.
[0008] As a further preferred embodiment of this technical solution, a transmission assembly is installed inside the metal cylinder. The transmission assembly includes a connecting disc one coaxially fixedly connected to one side of the inner circumference of the metal cylinder, and a connecting disc two coaxially fixedly connected to the other side of the outer circumference of the metal cylinder. The connecting disc one and the connecting disc two are coaxially fixedly connected to a horizontally arranged connecting shaft.
[0009] As a further preferred embodiment of this technical solution, the outer circumferences of the first connecting disc and the second connecting disc are jointly fixedly connected with a number of equally spaced connecting strips, and the inner circumference of the metal cylinder is provided with a number of sliding grooves that are adapted to the number of connecting strips.
[0010] As a further preferred embodiment of this technical solution, the same heat dissipation component is installed between the first connecting plate and the second connecting plate. The heat dissipation component includes several equally spaced mounting slots on the outer wall of one side of the first connecting plate. Each of the mounting slots has an L-shaped guide pipe fixedly connected inside. The guide pipe is perpendicular to the central axis of the connecting shaft, and the air inlet of the guide pipe is perpendicular to the first connecting plate. The second connecting plate has several air outlets inside.
[0011] When the roller rotates during operation, because the guide tube body is perpendicular to the central axis of the connecting shaft and the air inlet end face is perpendicular to the end face of the connecting plate one, external air will be drawn into the interior due to the rotation of the guide tube, and then enter the metal cylinder along its channel. The air pressure inside the metal cylinder increases, and it will flow out through the air outlet on the end face of the connecting plate two, ensuring that the air inside the metal cylinder is always kept close to the room temperature, which is beneficial to improving the heat dissipation efficiency of the roller and allowing the heat generated during the operation of the rubber coating layer to be conducted away more quickly.
[0012] As a further preferred embodiment of this technical solution, several heat sinks are fixedly connected between the first connecting plate and the second connecting plate, and the heat sinks are all in contact with the inner circumference of the metal cylinder.
[0013] As a further preferred embodiment of this technical solution, the heat sink is made of aluminum alloy.
[0014] As a further preferred embodiment of this technical solution, the extension head is configured in the shape of a frustum.
[0015] This utility model provides a ceramic wear-resistant roller, which has the following beneficial effects:
[0016] (1) By setting anti-slip components, this utility model enables the metal cylinder to provide leverage for the ceramic block, thereby ensuring that it will not displace excessively due to excessive stress during use, effectively preventing the ceramic block from falling off the coating layer. When connecting, simply align the extension head of the ceramic block inside the coating layer with the limiting groove on the surface of the metal cylinder. The limiting groove can play a positioning role, preventing the coating layer from shifting and allowing the coating process to proceed smoothly. When the roller is in use, if the ceramic block tends to shift due to stress, the extension head on its surface will also tend to move. The limiting groove can restrict the position of the extension head, effectively preventing the ceramic block from detaching from the coating layer due to repeated movement.
[0017] (2) By setting up a heat dissipation component, when the roller is rotating in operation, since the guide pipe body is perpendicular to the central axis of the connecting shaft and the air inlet end face is perpendicular to the end face of the connecting plate one, the external air will be injected into the interior due to the rotation of the guide pipe, and then enter the metal cylinder along its channel. The air pressure inside the metal cylinder increases and will flow out through the air outlet on the end face of the connecting plate two, ensuring that the air inside the metal cylinder is always kept close to the room temperature, which is conducive to improving the heat dissipation efficiency of the roller and allowing the heat generated during the working process of the rubber coating layer to be conducted out more quickly.

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a ceramic wear-resistant roller includes a metal cylinder 1. Two rubber coating layers 2 are bonded to the outside of the metal cylinder 1, and the two rubber coating layers 2 completely cover the outer surface of the metal cylinder 1. Several anti-slip components 3 are installed inside the two rubber coating layers 2 at equal intervals. The anti-slip components 3 include a ceramic block 301 vulcanized and embedded inside the rubber coating layer 2. The end of the ceramic block 301 away from the metal cylinder 1 extends out of the rubber coating layer 2. An extension head 302 is coaxially fixed to the outer wall of the end of the ceramic block 301 close to the metal cylinder 1. A limiting groove 303 adapted to the extension head 302 is opened on the outer surface of the metal cylinder 1.
[0025] During the connection process, simply align the extension head 302 of the ceramic block 301 inside the rubber layer 2 with the limiting groove 303 on the surface of the metal cylinder 1. The limiting groove 303 can play a positioning role, which can prevent the position of the rubber layer 2 from shifting, so that the coating process can proceed smoothly. When the roller is in use, if the ceramic block 301 tends to shift due to stress, the extension head 302 on its surface will also tend to move. The limiting groove 303 can restrict the position of the extension head 302, effectively preventing the ceramic block 301 from detaching from the rubber layer 2 due to repeated movement.
[0026] like Figure 2 and Figure 3 As shown, a transmission assembly 4 is installed inside the metal cylinder 1. The transmission assembly 4 includes a connecting disc 401 coaxially fixedly connected to one side of the inner circumference of the metal cylinder 1, and a connecting disc 402 coaxially fixedly connected to the other side of the outer circumference of the metal cylinder 1. A horizontally arranged connecting shaft 403 is coaxially fixed to the connecting disc 401 and the connecting disc 402.
[0027] The outer circumferences of connecting disc 1 (401) and connecting disc 2 (402) are fixedly connected with several equally spaced connecting strips 404. The inner circumference of the metal cylinder 1 is provided with several grooves that are adapted to the connecting strips 404, which helps to reduce the stress on the weld between the connecting disc and the metal cylinder 1.
[0028] When the drum rotates during operation, since the body of the guide pipe 502 is perpendicular to the central axis of the connecting shaft 403, and the end face of the air inlet is perpendicular to the end face of the connecting plate 401, external air will be drawn into the interior due to the rotation of the guide pipe 502, and then enter the metal cylinder 1 along its channel. The air pressure inside the metal cylinder 1 increases, and it will flow out through the air outlet 503 on the end face of the connecting plate 402, ensuring that the air inside the metal cylinder 1 is always kept close to the room temperature, which is beneficial to improving the heat dissipation efficiency of the drum and allowing the heat generated by the rubber coating layer 2 during operation to be conducted away more quickly.
[0029] like Figure 2 and Figure 3 As shown, a heat dissipation component 5 is installed between connecting plate 1 401 and connecting plate 2 402. The heat dissipation component 5 includes several equally spaced mounting slots 501 on the outer wall of one side of connecting plate 1 401. Each of the mounting slots 501 has an L-shaped guide pipe 502 fixedly connected inside. The guide pipe 502 is perpendicular to the central axis of the connecting shaft 403, and the air inlet of the guide pipe 502 is perpendicular to the connecting plate 1 401. Several air outlets 503 are opened inside the connecting plate 2 402.
[0030] Several heat sinks 504 are fixedly connected between connecting plate 1 401 and connecting plate 2 402, and the heat sinks 504 are all in contact with the inner circumference of the metal cylinder 1, which helps to increase the contact area between the metal cylinder 1 and the air, thereby further improving the heat dissipation effect.
[0031] like Figure 3 As shown, the heat sink 504 is made of aluminum alloy, which has good thermal conductivity and does not add too much weight to the roller.
[0032] like Figure 4 As shown, the extension head 302 is shaped like a frustum, which makes the docking process more convenient and has a higher fault tolerance.
[0033] This utility model provides a ceramic wear-resistant roller, the specific working principle of which is as follows:
[0034] During installation, glue is first applied to the surface of the metal cylinder 1, then glue is applied to the side of the rubber coating layer 2 that contacts the metal cylinder 1. The sheet-like rubber coating layer 2 is then placed over the outside of the metal cylinder 1. During assembly, the extension head 302 of the ceramic block 301 inside the rubber coating layer 2 is aligned with the limiting groove 303 on the surface of the metal cylinder 1. The limiting groove 303 provides a positioning effect, preventing the rubber coating layer 2 from shifting position and ensuring a smooth coating process. When the roller is in use, if the ceramic block 301 tends to shift position due to stress, the extension head 302 on its surface will also tend to move. The limiting groove 303 restricts the position of the extension head 302, effectively preventing the ceramic block 301 from detaching from the rubber coating layer 2 due to repeated movement. Furthermore, the frustum-shaped design of the extension head 302 makes the assembly process more convenient and has a higher fault tolerance.
[0035] When the drum rotates during operation, since the body of the guide pipe 502 is perpendicular to the central axis of the connecting shaft 403, and the end face of the air inlet is perpendicular to the end face of the connecting plate 401, external air will be drawn into the interior due to the rotation of the guide pipe 502, and then enter the metal cylinder 1 along its channel. The air pressure inside the metal cylinder 1 increases, and it will flow out through the air outlet 503 on the end face of the connecting plate 402, ensuring that the air inside the metal cylinder 1 is always kept close to the room temperature, which is beneficial to improving the heat dissipation efficiency of the drum and allowing the heat generated by the rubber coating layer 2 during operation to be conducted away more quickly.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
